Description

Technical Field

[0001] This utility model relates to the technical field of high-temperature sintering equipment for powder materials, and in particular to a double-track fully automatic pusher plate sintering furnace for continuous sintering of raw material powder. Background Technology

[0002] High-temperature sintering of raw material powders is a key process in powder metallurgy, ceramics, and the preparation of new energy materials. By heating at high temperatures, diffusion, flow, and reactions occur between powder particles, ultimately obtaining a dense bulk material with specific microstructure and properties. This process requires extremely high precision in temperature profiles and stability of the furnace atmosphere, directly affecting the final performance and consistency of the product.

[0003] Currently, the commonly used equipment for this process is the pusher plate sintering furnace, which continuously sinters by pushing refractory pushers carrying raw materials through the preheating, sintering, and cooling zones of the furnace body. To improve efficiency, the industry has developed a dual-channel pusher plate sintering furnace, which sets up two sintering channels in parallel within a single furnace body. However, during long-term continuous operation, the high-temperature friction between the refractory plates and the guide grooves of such existing equipment continuously generates debris and dust. This debris accumulates in the guide grooves and cannot be discharged in time, which not only significantly aggravates abnormal wear on the track and pushers but also increases the running resistance of the pushers and may even cause jamming, seriously affecting the continuity and stability of production. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a double-channel fully automatic pusher plate sintering furnace for continuous firing of raw material powder, which solves the problem of track jamming and abnormal wear caused by debris accumulation in the existing double-channel pusher plate sintering furnace.

[0005] This utility model also provides a double-track fully automatic pusher plate sintering furnace for continuous firing of raw material powder, as described above. Two guide blocks are fixedly connected to the upper surface of the frame, each guide block having a guide groove. A separation plate is fixedly installed on the frame, and two guide grooves are provided on the side surface of the separation plate. Multiple discharge holes are provided on the inner surfaces of both guide grooves. A sintering plate is slidably connected between each of the guide grooves. Two mounting blocks are fixedly connected to the rear surface of each of the two sintering plates, and brush heads are fixedly connected to the bottom surface of each mounting block. An internal drive shaft is rotatably connected to the frame. Two drive rollers are fixedly mounted on the outer surface of the drive shaft, and a conveyor belt is provided on the outer surface of each drive roller. Several driven shafts are rotatably connected to the frame on one side of the drive shaft. Two driven rollers are fixedly mounted on the outer surface of each driven shaft, and both driven rollers are connected to the conveyor belt. The brush head can automatically clean the debris and dust in the track during the movement of the push plate and discharge it through the discharge hole. This effectively solves the jamming problem caused by debris accumulation in traditional equipment, significantly reduces track wear, and the dual channels can achieve synchronous and stable material conveying.

[0006] Preferably, a drive gear is fixedly connected to one end of the drive shaft that passes through the frame, and a number of driven shafts are fixedly connected to driven gears at one end that passes through the frame. A transmission belt meshes with the outer surfaces of the drive gears and the driven gears. The mechanical structure ensures the synchronous operation of all driven shafts, fundamentally solving the technical problem of asynchronous movement of the dual-channel push plate.

[0007] Preferably, a limiting plate is fixedly connected to the side surface of the frame, and the limiting plate is movably connected to the drive shaft and the driven shaft; the limiting plate can effectively limit the transmission belt surrounding the drive gear and the driven gear radially, fundamentally preventing the transmission belt from falling off or running off track under high speed or load fluctuation.

[0008] Preferably, a rotating motor is fixedly mounted on the side surface of the frame, and the output end of the rotating motor is fixedly connected to the drive shaft; this simplifies the transmission chain, improves power transmission efficiency, and reduces equipment complexity and manufacturing costs.

[0009] Preferably, multiple fixing blocks are fixedly installed on the bottom surface of the frame, and a collection box is movably connected to the inner surface of the multiple fixing blocks. A handle is fixedly connected to the side surface of the collection box. The handle structure facilitates the operator to quickly pick up and put down the collection box, realizing centralized processing and regular cleaning of debris, greatly improving the convenience of equipment maintenance and ensuring the cleanliness of the production environment.

[0010] Both preferred conveyor belts have multiple limiting blocks on their outer surfaces; the limiting blocks directly contact the push plate to generate propulsion force, effectively avoiding slippage that may occur in traditional friction propulsion methods, and ensuring the accuracy of the push plate's travel distance and the reliability of the propulsion action.

[0011] Preferably, an insulation shell is fixedly installed on the upper surface of the frame, and a protective shell is fixedly installed on the side surface of the frame; the insulation shell effectively reduces heat loss and improves thermal efficiency; the protective shell isolates the moving parts, preventing foreign objects from entering and ensuring operational safety, thus jointly improving the overall performance of the equipment.

[0012] Beneficial effects: The dual-track fully automatic pusher plate sintering furnace for continuous calcination of raw material powder in this technical solution achieves automatic cleaning and precise synchronization of equipment operation through the coordinated operation of the self-cleaning system of the guide groove and the gear synchronous transmission system.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-7 This utility model discloses a double-track fully automatic pusher plate sintering furnace for continuous sintering of raw material powder, which includes a frame 1. The frame 1 serves as an integral support structure and is formed by welding of structural steel. Two guide blocks 2 are symmetrically fixed to the upper surface of the frame 1 by bolts. The guide blocks 2 are made of wear-resistant alloy steel and have guide grooves 5. A separation plate 3 is vertically fixed in the middle of the frame 1 to divide the furnace space into two independent sintering channels. Guide grooves 4 are machined on both sides of the separation plate 3. The guide grooves 5 and 4 are precisely aligned in space to form a complete high-precision sliding track.

[0019] Multiple discharge holes 15 are evenly opened on the bottom surface of guide groove 1 5 and guide groove 2 4. The refractory plate 6 is made of high alumina refractory material, and its two sides are slidably embedded in the guide rail. Two mounting blocks 16 are fixed to the rear of the refractory plate 6 by bolts. High temperature resistant ceramic fiber brush head 22 is installed on the bottom surface of the mounting block 16.

[0020] A rotating motor 18 is fixed on the side of the frame 1 via a motor mount. A servo motor is preferred. The output end of the rotating motor 18 is directly connected to the drive shaft 9 via a coupling. The drive shaft 9 is rotatably connected inside the frame 1 via a bearing seat. One end of the drive shaft 9 extends out of the frame 1 and is fixed to the drive gear 8 via a key.

[0021] Multiple driven shafts 19 are arranged in parallel inside the frame 1 and are rotatably connected by bearing seats. A driven gear 21 is fixed at the corresponding end of each driven shaft 19. A drive gear 8 and the outer surface of the driven gear 21 are meshed with a transmission belt 10. A limiting plate 11 is provided on the side of the frame 1 and is movably connected to the transmission shaft 10 and the driven shaft 19.

[0022] Two driving rollers 12 are fixed on the driving shaft 9, and two driven rollers 20 are fixed on the driven shaft 19 respectively. Two annular conveyor belts 13 are respectively sleeved on the driving rollers 12 and driven rollers 20 to form an independent transmission circuit. Multiple heat-resistant steel limit blocks 7 are fixed at equal intervals on the outer surface of the conveyor belts 13.

[0023] Multiple fixing blocks 24 are fixed to the bottom surface of the frame 1 by bolts. A collection box 23 is movably connected inside the fixing block 24. The collection box 23 is located directly below the discharge hole 15. A handle 25 is fixed to the side of the collection box 23 for easy picking and putting. An insulation shell 14 is fixed to the upper surface of the frame 1 and filled with fire-resistant insulation material. A protective shell 17 is fixed to the side surface of the frame 1 to completely cover the transmission components.

[0024] Working principle: The power of the entire system begins with the start of the rotating motor 18. The rotational power output by the motor directly drives the drive shaft 9 to rotate. The drive gear 8, fixed at one end of the drive shaft, rotates accordingly, synchronously distributing the power to each driven shaft 19. Mechanically, this forces all driven shafts 19 to maintain the same speed and phase as the drive shaft 9, laying a solid foundation for subsequent synchronous transmission.

[0025] Based on the synchronous transmission of power, the two driving rollers 12 fixed on the driving shaft 9 and the driven rollers 20 fixed on each driven shaft begin to rotate synchronously, thereby precisely driving the two conveyor belts 13 to run at the same linear speed. The limiting block 7 fixed on the outer surface of the conveyor belt moves at a uniform speed. When the heat-resistant plate 6 is placed at the starting end of the track, its tail is reliably pushed by the limiting block 7 that has moved there.

[0026] During the advancement process, the two sides of the heat-resistant plate 6 are strictly confined within a closed high-precision track formed by the guide groove 5 on the guide block 2 and the guide groove 4 on the separation plate 3. When the heat-resistant plate 6 moves within the track, the brush head 22 fixed to the bottom of the mounting block 16 moves synchronously with the heat-resistant plate 6. The brush head 22 is designed with an arc-shaped structure that converges towards the center. The brush head 22 maintains contact with the bottom surface of the track at a specific angle. During the advancement process, it continuously scrapes away the debris and dust accumulated in the track. The cleaned debris moves along the track under the push of the brush head 22 and finally falls into the collection box 23 set below through the evenly distributed discharge holes 15.

[0027] The sintering plate 6, which is steadily pushed, carries the raw material powder and enters the furnace chamber composed of the heat insulation shell 14 at a uniform speed. The excellent heat insulation performance of the heat insulation shell 14 effectively reduces heat loss. The sintering plate 6 passes through the preset preheating zone, high-temperature sintering zone and cooling zone at a uniform speed in sequence. During this process, the raw material powder undergoes a precisely controlled temperature curve, completing the diffusion, bonding and densification between particles, and finally forming a product that meets the requirements.

[0028] The protective shell 17 completely covers moving parts such as gears and drive shafts, effectively preventing accidental contact by operators and ensuring personal safety during equipment operation, while also preventing the intrusion of dust and foreign objects.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
