Technical Field

[0001] This utility model relates to the field of solid compound processing technology, specifically a preheating device for solid compound processing. Background Technology

[0002] A preheating device for solid compound processing is a device used to preheat solid compounds before they undergo major processing (such as chemical reactions, physical transformations, etc.). Its main function is to raise the solid compound from room temperature or initial temperature to a specific intermediate temperature range that is more conducive to subsequent processing. By preheating, the reaction time or conversion time of the main processing steps can be shortened, processing efficiency can be improved, and the processing process can be made more stable, reducing product quality problems caused by factors such as sudden temperature changes.

[0003] However, existing preheating devices for solid compound processing lack the function of breaking up agglomerated solid compound raw materials and controlling the falling speed of solid compounds of different particle sizes. During use, agglomerated solid compounds with larger particle sizes fall quickly and cannot be fully preheated, resulting in poor preheating effect. Utility Model Content

[0004] The purpose of this invention is to provide a preheating device for processing solid compounds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This preheating device for processing solid compounds comprises grinding blocks, grinding covers, grid plate one, grid plate two, and grid plate three. In use, the air supply pipe is opened to deliver hot air into the device. The hot air enters the device through the air diffuser and gradually rises. Solid compound raw materials are added into the device through the feed inlet. The motor is started, driving the grinding blocks and rotating rod to rotate. The raw materials are ground and squeezed by the grinding cover and grinding blocks, falling onto grid plate one, through slot one, onto grid plate two, and through slot two, onto grid plate three. During the descent, the raw materials exchange heat with the hot air. Finally, the preheated solid compound raw materials pass through the discharge port.

[0014] 2. This preheating device for processing solid compounds, through the arrangement of a rotating rod, a prying block, a fixed block, and a spring, is used such that when the motor drives the rotating rod to rotate, the prying block on the outer surface of the rotating rod contacts the fixed block and moves it, causing the grid plate to move into the annular groove, compressing the spring. Under the action of the spring, the grid plate returns to its position. The rotating rod rotates and repeats the above steps, continuously vibrating the grid plate to prevent some solid compounds from getting stuck in the groove, while cleaning the dust adhering to the inner wall of the device.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-Figure 4 As shown, this utility model provides a technical solution:

[0022] A preheating device for processing solid compounds includes a feed pipe 1, with a grinding cover 2 connected to the bottom of the feed pipe 1. A grinding block 3 is slidably connected to the lower surface of the grinding cover 2. A housing 4 is fixedly connected to the outer surface of the feed pipe 1. A motor 5 is fixedly connected to the inner wall of the housing 4 near the grinding block 3. One end of the output shaft of the motor 5 is fixedly connected to the grinding block 3, and the other end of the output shaft of the motor 5 is fixedly connected to a rotating rod 6. A grid plate 1 7 is fixedly connected to the inner wall of the housing 4 near the center. A grid plate 2 8 and a grid plate 3 9 are fixedly connected to the inner wall of the housing 4 near the grid plate 2 8. An air supply pipe 10 is inserted into the side of the housing 4 near the bottom. One end of the air supply pipe 10 near the housing 4 is connected to a diffuser pipe 11. In use, the air supply pipe 10 is opened to supply hot air into the device. The hot air passes through the diffuser pipe. The material enters the device through the hole 20 and gradually rises, allowing the solid compound raw material to be added into the device from the feed port. The motor 5 is started, driving the grinding block 3 and the rotating rod 6 to rotate. The raw material is squeezed and ground by the grinding cover 2 and the grinding block 3 and falls onto the grid plate 1 7, then falls onto the grid plate 2 8 through the hole groove 1 21, and finally falls onto the grid plate 3 9 through the hole groove 22. During the descent of the raw material, it exchanges heat with the hot air. Finally, when it passes through the discharge port 14, it is a preheated solid compound raw material. Grinding can break up the clumps of raw material. Different grid plates buffer the falling speed of solid compounds of different particle sizes, thereby making the preheating more uniform and effective. Small solid compounds have a larger specific surface area and can better contact with hot gas during the preheating process. At the same time, the shape of the grinding block 3 and the grinding cover 2 makes the raw material fall in a dispersed manner and can better contact with hot air.

[0023] In this embodiment, preferably, a plurality of protrusions 12 are fixedly connected to the lower surface of the grinding cover 2, and a plurality of protrusions 23 are fixedly connected to the upper surface of the grinding block 3. In use, the solid compound raw material is added into the device through the feed port, the motor 5 is started, and the grinding block 3 and the rotating rod 6 are driven to rotate. The raw material is crushed and ground by the grinding cover 2 and the grinding block 3 and falls onto the grid plate 7. The protrusions 12 and 23 collide and rub continuously during the rotation of the grinding block 3, crushing and breaking up the clumps of solid compound raw material, which facilitates better preheating of the raw material.

[0024] In this embodiment, preferably, the bottom of the shell 4 is provided with a discharge port 14, and the top of the shell 4 is connected to an air outlet pipe 15 on the side away from the feed pipe 1. A filter plate 16 is fixedly connected to the inner wall of the air outlet pipe 15. In use, the air supply pipe 10 is opened to supply hot air into the device. The hot air enters the device through the air diffuser 20 and gradually rises. During the rising process, the solid compound is preheated. Then it rises to the air outlet pipe 15. Since some solid compound particles are extremely small, they are easy to rise with the hot air and flow out of the device, polluting the external environment of the device. The filter plate 16 with small-diameter holes and grooves can effectively solve this problem.

[0025] In this embodiment, preferably, the inner wall of the housing 4 is provided with several annular grooves 17. A spring 18 is fixedly connected to the inner wall of the annular groove 17. A grid plate 1 7, a grid plate 2 8, and a grid plate 3 9 are fixedly connected to the end of the spring 18 away from the housing 4, respectively. A fixing block 19 is fixedly connected to the side of the grid plate 1 7, the grid plate 2 8, and the grid plate 3 9 near the rotating rod 6. Several toggle blocks 24 are fixedly connected to the outer surface of the rotating rod 6. The fixing block 19 is slidably connected to the side of the toggle block 24 near the fixing block 19. In use, the motor 5 drives the rotating rod 6 to rotate. The toggle block 24 on the outer surface of the rotating rod 6 contacts the fixing block 19 and moves, causing the grid plate to move into the annular groove 17 and squeeze the spring 18. Under the action of the spring 18, the grid plate returns to its position. The rotating rod 6 rotates and repeats the above steps to continuously vibrate the grid plate, prevent some solid compounds from getting stuck in the groove, and clean the dust attached to the inner wall of the device.

[0026] In this embodiment, preferably, the air vent 11 has several air holes 20, the grid plate 7 has several slots 21, the grid plate 8 has several slots 22, and the grid plate 9 has several slots 23. In use, the raw material is crushed and ground by the grinding cover 2 and the grinding block 3 and falls onto the grid plate 7, passes through slots 21 and falls onto the grid plate 8, and passes through slots 22 and falls onto the grid plate 9. During the descent of the raw material, it exchanges heat with the hot air. The pore size limitation causes solid compound particles of different sizes to have different speeds when passing through the grid plate. Small particles can pass through quickly and their falling speed is relatively fast, but due to the layered obstruction of the grid plate, they will not pass through the entire device too quickly. Large particles stay on the grid plate for a relatively long time, thus buffering their falling speed.

[0027] In this embodiment, preferably, the diameters of slot 1 21, slot 22, and slot 3 23 decrease sequentially. During use, the raw material is crushed and ground by the grinding cover 2 and the grinding block 3 and falls onto grid plate 1 7, passes through slot 1 21 and falls onto grid plate 2 8, and passes through slot 2 22 and falls onto grid plate 3 9. During the descent of the raw material, it exchanges heat with hot air. The different diameters of the slots are set to different degrees to which the solid compound falls. Generally speaking, the solid compound particles that have not passed through the first layer of screening have a slightly larger diameter, while the solid compound particles that have passed through the last layer of grid plate have a smaller diameter.

[0028] Working principle: In this embodiment, a preheating device for processing solid compounds is used by opening the air supply pipe 10 to deliver hot air into the device. The hot air enters the device through the air diffuser 20 and gradually rises. The solid compound raw material is added into the device through the feed port. The motor 5 is started, which drives the grinding block 3 and the rotating rod 6 to rotate. The raw material is squeezed and ground by the grinding cover 2 and the grinding block 3 and falls onto the grid plate 1 7, then onto the grid plate 2 8 through the first slot 21, and onto the grid plate 3 9 through the second slot 22. During the descent of the raw material, it exchanges heat with the hot air. Finally, when it passes through the discharge port 14, it is the preheated solid compound raw material. The motor 5 drives the rotating rod 6 to rotate. The paddle 24 on the outer surface of the rotating rod 6 contacts the fixed block 19 and moves it, causing the grid plate to move into the annular groove 17, squeezing the spring 18. Under the action of the spring 18, the grid plate returns to its position. The rotating rod 6 rotates and repeats the above steps, continuously vibrating the grid plate.
