Horizontal Tubular Chain Conveyor

The Horizontal Tubular Chain Conveyor (standard configuration: food/chemical grade; custom options available: explosion-proof/aseptic/high-temperature resistant) is a closed-loop horizontal conveying system designed specifically for powders, granules, and small lumps. Leveraging the company's years of experience in material handling and fluid system integration, it utilizes a core design of "closed-loop tubular chain traction + modular assembly + safety interlock protection." Employing flange quick-installation/floor-mounted/support integrated structures, it boasts advantages such as compact footprint, stable conveying, dust-free operation, low energy consumption, convenient maintenance, and ample safety redundancy. Manufactured in strict accordance with GB 12476, GB/T 19815, ISO 14644, and 3A hygiene standards, it is suitable for temperatures from room temperature to 80℃ (a 120℃ high-temperature version is available upon customization), with conveying lengths up to 100m and conveying capacities from 1 to 50 tons. With a capacity of m³/h, this multi-condition conveyor is widely used in horizontal material conveying in industries such as food processing, biopharmaceuticals, fine chemicals, lithium battery materials, feed processing, plastic granules, and mining powders. It completely solves the industry pain points of traditional screw conveyors, such as high dust levels, excessive material residue, material jamming, and inability to adapt to clean/explosion-proof conditions. It achieves **zero dust leakage, residue-free material conveying, and fully controllable closed horizontal conveying**, helping companies pass various stringent certifications and environmental inspections such as GMP, explosion-proof certificates, and food hygiene and safety certifications.

As a core material horizontal conveying equipment for clean, explosion-proof, and dust-free production scenarios, this product focuses on the dual functions of "closed-loop tubular chain horizontal conveying + full-process safety protection." These three functions work together to connect upstream and downstream equipment such as raw material warehouses, mixing equipment, metering units, packaging lines, and silos, achieving triple protection of materials being dust-free, residue-free, and free from cross-contamination. It balances conveying efficiency and operational stability, and is suitable for demanding conditions such as aseptic production, explosion-proof workshops, and fine powder processing.

Closed-loop zero-leakage material conveying : Adopting a fully sealed steel/stainless steel pipe cavity, with built-in high-strength wear-resistant chain + special disc/scraper, the material is continuously and smoothly pushed in the pipeline, with no dust spillage throughout the process and a powder leakage rate of <0.01%, eliminating workshop dust, material moisture, and cross-contamination problems; It can convey a variety of materials from ultrafine powders (such as flour, pharmaceutical powders, lithium battery cathode materials) to small particles (such as plastic particles, nuts, granular medicines), and the materials are almost undamaged and residue-free. The inner wall of the pipeline is smooth and has no dead corners, meeting the high purity and cleanliness requirements of the food and pharmaceutical industries.

Differential pressure/blockage/temperature linkage early warning + low energy consumption and long-term operation and maintenance : The standard PLC online monitoring system has preset three thresholds for differential pressure, blockage, and over-temperature. Abnormalities will trigger an automatic alarm and emergency shutdown. It adopts a low-resistance chain drive and load-equalizing disc design, and its operating energy consumption is 25%~30% lower than that of traditional screw conveyors. The discs/chains/pipes adopt a quick-release buckle + sealing ring structure, which can be disassembled, cleaned and replaced by a single person without tools. The service life of vulnerable parts can reach 1~2 years under normal temperature and clean working conditions. The pre-filtered dustproof end cover can be repeatedly cleaned, which greatly reduces operation and maintenance costs and downtime losses.

Explosion-proof and sterile dual safety protection + wear-resistant design : Utilizing a tenon-and-mortise seal + double silicone rubber sealing ring structure, the enclosure and piping are integrally welded, ensuring excellent sealing performance. The explosion-proof model is equipped with an explosion-proof motor, anti-static chain, and spark detection and extinguishing system, complying with GB3836 standards and suitable for flammable and explosive dust/gas environments. The sterile and hygienic model is made of 316L stainless steel, polished without dead corners, and can withstand CIP/SIP online cleaning and sterilization, meeting GMP and FDA hygiene requirements. It also features overload protection, chain breakage detection, and anti-reverse device to prevent abnormal system damage and ensure long-term safe and stable operation of the equipment.

1. Compact footprint and highly adaptable

With its horizontal modular layout, it can be flexibly assembled according to the workshop layout, without the need for complex transfer equipment. It occupies only 40% of the area of traditional belt conveyors, making it particularly suitable for space-constrained scenarios such as clean rooms, small workshops, and multi-level production lines. It can achieve straight horizontal conveying, and can also be equipped with corner modules to achieve 90°~180° turning conveying, directly connecting to upstream and downstream equipment. The flange interface complies with GB/T 9113 standard, and can be directly connected to existing silos and production lines without large-scale modifications, adapting to various workshop layout requirements.

2. Modular customization, covering all material types.

We can flexibly customize pipe diameter, chain material, disc type (flexible/rigid), and conveying length according to customer material characteristics and working conditions; materials include 304 stainless steel, 316L stainless steel, and carbon steel with anti-corrosion coating; anti-stick coating pipes are available for viscous materials, and wear-resistant ceramic lining is available for abrasive materials; from ultrafine powders to small particles, from room temperature to high temperature, from ordinary working conditions to explosion-proof/sterile conditions, we provide full coverage and can meet the personalized conveying needs of different industries.

3. Low energy consumption and low noise, resulting in outstanding economic efficiency in operation.

The optimized chain drive and lightweight disc design significantly reduce motor power requirements, resulting in energy consumption that is more than 25% lower than traditional horizontal conveyor equipment. The sealed pipeline structure effectively isolates operating noise, with operating noise ≤65dB(A) (floor-mounted model), far below workshop noise standards. The lifespan of vulnerable parts is clearly defined, and the replacement cycle can be precisely controlled through online monitoring, reducing downtime and consumable procurement costs, resulting in outstanding long-term economic efficiency.

4. Materials are compliant, testing is complete, and certification is worry-free.

Components in contact with materials can be made of 316L food-grade stainless steel, meeting 3A hygiene standards; explosion-proof components have all passed GB3836 third-party testing and certification; each unit undergoes no-load/load test operation, sealing leakage test, chain tension test, and safety interlock function test before leaving the factory; third-party testing reports, material certificates (MTC), explosion-proof certificates, and hygiene certification reports can be provided, fully complying with various stringent certification requirements and helping companies successfully pass environmental and hygiene audits.
