Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory material drying technology, specifically to a refractory material drying device. Background Technology
[0002] In the production process of refractory materials, some granular raw materials need to be dried before processing, mainly to remove moisture, improve material performance, or avoid problems in subsequent processes. In order to extend the drying time of refractory materials in a limited space, some drying equipment has a special design for the movement trajectory of refractory materials.
[0003] For example, the patent with authorization announcement number CN220871381U discloses a refractory material drying device. By setting a shaking component, the conveyor cover slides on the surface of two trapezoidal slide rails, allowing the refractory material to slide on the surface of the conveyor cover. Under the action of multiple guide plates, the sliding time of the refractory material on the conveyor cover is increased, which enhances the drying effect. However, there are still areas for improvement.
[0004] Firstly, the refractory material particles slide down the guide plate layer by layer, and the drying efficiency of the bottom particles is lower than that of the top particles, resulting in poor drying uniformity.
[0005] Secondly, the granules may clump together due to moisture. Unbroken granule clumps have low drying efficiency due to the granules wrapped inside. Moreover, the clumps of granules need to be broken up before subsequent processes, which increases the number of work steps and reduces production efficiency. Utility Model Content
[0006] To address the aforementioned issues, this application provides a refractory material drying device that solves the problems of insufficient exchange of particle positions at different levels during particle descent, resulting in inconsistent drying efficiency and the failure to break up clumps of particles.
[0007] A refractory material drying device includes a bin body, an inclined feeding plate is movably installed on the inner side of the bin body, and multiple first inclined baffles and second inclined baffles are alternately installed on the top of the inclined feeding plate. Multiple horizontal through holes for bottom particle flow are opened through the middle of the first inclined baffles and second inclined baffles.
[0008] A screen plate for filtering particles is fixedly installed on the top of the inclined feeding plate, and a horn tube for feeding is movably installed on the top of the screen plate. The screen plate shakes and cooperates with the edge of the horn tube to squeeze the particle clusters.
[0009] Furthermore, the sieve plate and the side of the horn tube that are close to each other are both treated with a frosted finish.
[0010] Furthermore, a feed box is fixedly installed at the top of the horn tube, and the feed box is fixedly installed at the top of the silo body.
[0011] Furthermore, multiple hot air dryer bodies are installed on the outside of the silo.
[0012] Furthermore, a discharge port is provided through the end of the hopper, and the discharge port cooperates with the bottom of the inclined discharge plate.
[0013] Furthermore, the first inclined baffle and the second inclined baffle are inclined, with the lower end of both extending towards the middle of the inclined feed plate.
[0014] Furthermore, a motor is fixedly installed on the outside of the bin body, the motor output shaft passes through the outside of the bin body, a drive shaft is fixedly installed on the motor output shaft, a reciprocating lead screw is fixedly installed in the middle of the drive shaft, the reciprocating lead screw is coupled to the inclined feeding plate, and the end of the drive shaft away from the motor is rotatably installed inside the bin body.
[0015] Furthermore, a limiting post is slidably installed through the bottom of the inclined feeding plate, with both ends of the limiting post fixedly installed inside the hopper.
[0016] The beneficial effects of this utility model are as follows:
[0017] The refractory material drying device of this utility model has horizontal through holes in the middle of the first inclined baffle and the second inclined baffle. The particles slide down along the first inclined baffle and the second inclined baffle. Some particles at the bottom will pass through the horizontal through holes and reach the middle and upper layers of the particle layer. Moreover, due to the lack of particles in the lower layer, the particles in the middle and upper layers will also move down. This process is repeated many times, so that the layer in which the particles are located changes continuously. The drying efficiency of all particles is basically the same, thus optimizing the drying effect of the particles.
[0018] When the granules move along the screen plate to the narrow part of the screen plate and the trumpet tube, they are crushed and then pass through the screen plate mesh. The granules are crushed in advance, which makes the drying of the granules more uniform and eliminates the need to add a crushing mechanism in the subsequent process, thus improving the overall production efficiency.

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0028] First embodiment:
[0029] like Figure 1 , Figure 2 , Figure 4 As shown, this utility model embodiment provides a refractory material drying device, including a bin body 1. An inclined feeding plate 7 is movably installed inside the bin body 1. Multiple first inclined baffles 11 and second inclined baffles 12 are alternately installed on the top of the inclined feeding plate 7. Multiple horizontal through holes 14 for bottom particle flow are opened through the middle of the first inclined baffles 11 and second inclined baffles 12. The horizontal through holes 14 are horizontally arranged. The first inclined baffles 11 and second inclined baffles 12 are installed along the inclined feeding plate 7, therefore (as shown in the figure). Figure 2 As shown, the distance between the left opening of the horizontal through hole 14 and the inclined feed plate 7 is less than the distance between the right opening of the horizontal through hole 14 and the inclined feed plate 7.
[0030] Specifically, the first inclined baffle 11 and the second inclined baffle 12 are inclined, and the end of both extending toward the middle of the inclined feed plate 7 is the lower end.
[0031] In this embodiment, the particles bend and slide down along the first inclined baffle 11 and the second inclined baffle 12. Some particles at the bottom will pass through the horizontal through hole 14 to reach the middle and upper layers of the particle layer. Moreover, due to the lack of particles in the lower layer, the particles in the middle and upper layers will also move down. This process is repeated many times, so that the layer in which the particles are located changes continuously, and the drying efficiency of all particles is basically the same, thus optimizing the drying effect of the particles.
[0032] Second embodiment:
[0033] The difference from the above embodiments is that, as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a sieve plate 13 for filtering particles is fixedly installed on the top of the inclined feeding plate 7, and a horn tube 3 for feeding is movably installed on the top of the sieve plate 13. The sieve plate 13 shakes and cooperates with the edge of the horn tube 3 to squeeze the particle cluster.
[0034] Specifically, the sieve plate 13 and the trumpet tube 3 are both frosted on the side closest to each other to increase friction and prevent slippage.
[0035] Specifically, the top of the horn tube 3 is connected to and fixedly installed with a feed box 2, which is fixedly installed on the top of the silo body 1.
[0036] Specifically, a motor 6 is fixedly installed on the outside of the hopper 1. The output shaft of the motor 6 passes through the outside of the hopper 1. A drive shaft 8 is fixedly installed on the output shaft of the motor 6. A reciprocating screw 9 is fixedly installed in the middle of the drive shaft 8. The reciprocating screw 9 is coupled and connected to the inclined feeding plate 7. The end of the drive shaft 8 away from the motor 6 is rotatably installed on the inside of the hopper 1.
[0037] In this embodiment, the motor 6 rotates, driving the drive shaft 8 and the reciprocating screw 9 to rotate, which in turn drives the inclined feeding plate 7 to oscillate back and forth. The granular material falls from the feed box 2 and the trumpet tube 3 to the screen plate 13. Small particles fall through the mesh of the screen plate 13, while clumps of particles are blocked above the screen plate 13. The screen plate 13 and the side of the trumpet tube 3 that are close to each other are both treated with sandblasting. When the clump of particles moves with the screen plate 13 to the narrow part of the screen plate 13 and the trumpet tube 3, it is squeezed and broken. Then it passes through the mesh of the screen plate 13, which breaks the clump of particles in advance, making the drying of the particles more uniform. There is no need to add a crushing mechanism in the subsequent process, thus improving the overall production efficiency.
[0038] Specifically, a limiting post 10 is slidably installed through the bottom of the inclined feeding plate 7 to restrict the movement trajectory of the inclined feeding plate 7 and make the movement of the inclined feeding plate 7 smoother. Both ends of the limiting post 10 are fixedly installed inside the hopper body 1.
[0039] Specifically, multiple hot air dryer bodies 4 are installed on the outside of the silo 1 for drying particles.
[0040] Specifically, the end of the silo 1 is provided with a discharge port 5, which is matched with the bottom of the inclined feeding plate 7. The dried particles flow from the discharge port 5 to the next production process.
[0041] Specific working methods:
[0042] When the hot air dryer body 4 is working, it heats the inside of the chamber 1. The motor 6 rotates, which drives the drive shaft 8 and the reciprocating screw 9 to rotate, thereby causing the inclined feeding plate 7 to sway back and forth.
[0043] Granular material falls from the feed box 2 and the horn tube 3 onto the screen plate 13. Small particles fall through the mesh of the screen plate 13, while clumps of particles are blocked above the screen plate 13. The screen plate 13 and the horn tube 3 are both frosted on the side closest to each other. When the clumps of particles move with the screen plate 13 to the narrow part of the screen plate 13 and the horn tube 3, they are crushed and then pass through the mesh of the screen plate 13. The clumps of particles are crushed in advance, which makes the drying of the particles more uniform and eliminates the need to add a crushing mechanism in subsequent processes, thus improving the overall production efficiency.
[0044] The particles bend and slide down along the first inclined baffle 11 and the second inclined baffle 12. Some particles at the bottom will pass through the horizontal through hole 14 to reach the middle and upper layers of the particle layer. Moreover, due to the lack of particles in the lower layer, the particles in the middle and upper layers will also move down. This process is repeated many times, so that the layer in which the particles are located changes continuously. The drying efficiency of all particles is basically the same, thus optimizing the drying effect of the particles.
[0045] The dried granules flow from outlet 5 to the next production process.
[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
