Description

Technical Field

[0001] This utility model relates to the field of diatomaceous earth technology, and in particular to a tunnel drying device. Background Technology

[0002] Diatomaceous earth floor mats are environmentally friendly floor protection products made primarily from natural diatomaceous earth. They are mainly used in damp environments such as bathrooms and toilets, and feature water absorption, slip resistance, antibacterial properties, and deodorization. Diatomaceous earth itself is a porous material with good water absorption and drying capabilities. However, during the production process, diatomaceous earth, as the main siliceous material, undergoes modification. Drying removes organic matter and impurities from the raw material, improving its purity. Simultaneously, it removes moisture, making the material more stable during subsequent processing, thereby enhancing the product's strength and durability.

[0003] In existing technologies, traditional tunnel dryers generally use simple screw conveying or gravity feeding methods. Due to the lack of effective dispersion, diatomaceous earth is prone to local accumulation when entering the drying area, resulting in uneven material thickness. This not only affects the hot air penetration efficiency and leads to uneven drying, but also causes hardness differences and stress concentration on the finished product foot pads. Therefore, we propose a tunnel drying device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tunnel-type drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Both synchronous pulleys are meshed with the synchronous transmission belt, and the transmission assembly enables the feeding roller and the reciprocating screw to rotate synchronously.

[0008] Preferably, two arc-shaped guide plates are fixedly connected to the bottom inner wall of the hopper, and the outer walls of the two arc-shaped guide plates are slidably connected to the outer wall of the discharge roller. The two arc-shaped guide plates are used to assist the diatomaceous earth in falling into the arc-shaped discharge trough.

[0009] Preferably, the outer wall of the movable component has two guide holes, and the inner walls of the two guide holes are slidably connected with guide rods. The two ends of the guide rods are respectively fixedly connected to the outer walls of the two fixed plates, and the movable component is moved stably by setting the guide rods.

[0010] Preferably, the outer walls of the hopper and one of the fixed plates are provided with through holes. The inner walls of the two through holes are rotatably connected to one end of the feed roller and the reciprocating screw, respectively. The other ends of the reciprocating screw and the feed roller are fixedly fitted with bearings. The two bearings are respectively embedded in the fixed plate and the hopper to assist the reciprocating screw and the feed roller in stable rotation.

[0011] Preferably, a motor is fixedly connected to the outer wall of another fixed plate, and one end of the motor output shaft is fixedly connected to the outer wall of the reciprocating lead screw.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-6 As shown, a tunnel-type drying device is disclosed, including a dryer body 1 (SD-500). A conveyor belt 2 is rotatably connected inside the dryer body 1 (SD-500). The conveyor belt 2 is made of high-temperature resistant fluororubber and has anti-slip texture on its surface. Two side plates 3 are fixedly connected to the top of the dryer body 1 (SD-500). A hopper 4 is fixedly connected between the two side plates 3. A discharge roller 5 is rotatably connected inside the hopper 4. Two arc-shaped guide plates 6 are fixedly connected to the bottom inner wall of the hopper 4. The arc-shaped guide plates 6 are provided with a polytetrafluoroethylene wear-resistant layer. The outer walls of the two arc-shaped guide plates 6 are slidably connected to the outer wall of the discharge roller 5. Multiple arc-shaped discharge grooves 7 are opened on the outer wall of the discharge roller 5.

[0024] The top of the dryer body 1 (SD-500) is fixedly connected to two fixed plates 8, and a reciprocating screw 9 is rotatably connected between the two fixed plates 8. The hopper 4 and the outer wall of one of the fixed plates 8 are both provided with through holes. The inner walls of the two through holes are rotatably connected to the feeding roller 5 and one end of the reciprocating screw 9, respectively. The outer wall of the other fixed plate 8 is fixedly connected to a motor, and one end of the motor output shaft is fixedly connected to the outer wall of the reciprocating screw 9.

[0025] A movable part 10 is threaded on the outer wall of the reciprocating screw 9. A self-lubricating bearing is installed between the movable part 10 and the reciprocating screw 9. Two guide holes are opened on the outer wall of the movable part 10. Guide rods 11 are slidably connected to the inner walls of the two guide holes. The two ends of the guide rods 11 are fixedly connected to the outer walls of the two fixed plates 8 respectively. A T-shaped plate 12 is fixedly connected to the bottom of the movable part 10. Multiple comb teeth 13 are fixedly connected to the bottom of the T-shaped plate 12.

[0026] The outer wall of the hopper 4 is provided with a transmission assembly, which includes a synchronous transmission belt 15. One end of the feed roller 5 and the reciprocating screw 9 are both fixedly fitted with synchronous pulleys 14. Both synchronous pulleys 14 are meshed with the synchronous transmission belt 15, and there is sufficient tension between the synchronous transmission belt 15 and the two synchronous pulleys 14.

[0027] Working principle: During use, diatomaceous earth is conveyed into the hopper 4 via an existing conveyor. The motor then drives the connected synchronous pulley 14 to rotate, which in turn drives the synchronous transmission belt 15 to rotate, thereby driving another synchronous pulley 14 to rotate. The rotation of the two synchronous pulleys 14 drives the reciprocating screw 9 and the feeding roller 5 to rotate. The rotation of the feeding roller 5 drives multiple arc-shaped feeding troughs 7 to rotate, and the diatomaceous earth is discharged downwards along with the rotation of the multiple arc-shaped feeding troughs 7, falling onto the conveyor belt 2 inside the dryer body 1. When entering the drying area, the reciprocating screw 9 drives the moving part 10 to move back and forth, and the reciprocating movement of the moving part 10 drives the bottom T-shaped plate 12 to move back and forth. The reciprocating movement of the T-shaped plate 12 drives the comb teeth 13 to move back and forth, thereby dispersing the fallen diatomaceous earth and avoiding local accumulation.
