[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A drying and curing device with exhaust gas purification function includes a workbench 1, a drying shell 2 fixedly connected to the top of the workbench 1, a purification mechanism 3 fixedly connected to the top of the drying shell 2, a drying mechanism 4 fixedly connected to the inner side of the drying shell 2, inlets and outlets 5 on both sides of the drying shell 2, support plates 6 fixedly connected to both sides of the inlets and outlets 5, a conveyor belt 7 arranged on the inner side of the support plate 6, a servo motor 8 installed on the front side of the right side of the right support plate 6, and the output end of the left side of the servo motor 8 passing through the support plate 6 and fixedly connected to the front side of the right side of the conveyor belt 7.

[0028] The purification mechanism 3 includes an exhaust shell 31, a purification shell 32, a filter frame 33, a top cover 34, and an exhaust pipe 35. The exhaust shell 31 is fixedly connected to the top of the drying shell 2, the purification shell 32 is fixedly connected to the top of the exhaust shell 31, the filter frame 33 is snapped into the inner side of the purification shell 32, the top cover 34 is slidably connected to the top of the exhaust shell 31, and the exhaust pipe 35 is fixedly connected to the top of the top cover 34.

[0029] In this embodiment: by setting the workbench 1 as the drying shell 2 and the purification mechanism 3, the drying shell 2 forms a relatively enclosed drying space, reducing heat loss and improving energy utilization efficiency, while preventing exhaust gas from leaking into the workshop environment. The inlet and outlet 5 facilitates the conveyor belt 7 to send the material to be dried into and out of the drying shell 2, realizing continuous production. The support plate 6 provides stable support for the conveyor belt 7, ensuring its smooth operation. The conveyor belt 7 allows hot air to penetrate the material, improving drying efficiency. The servo motor 8 drives the conveyor belt 7 through the connecting shaft 10, which can control the conveying speed and adapt to the drying process requirements of different materials. The exhaust shell 31 can expel the exhaust gas generated in the drying shell 2 upwards. The air is guided to the inside of the purification shell 32. The purification shell 32 can support and limit the filter frame 33 and the top cover 34. The filter frame 33 can limit the activated carbon particles 11. At the same time, the surface of the filter frame 33 is set as a filter mesh, so that the exhaust gas can pass through the filter frame 33 and come into contact with the activated carbon particles 11, and continue to move upward through the top of the filter frame 33. The top cover 34 can support and limit the exhaust pipe 35, and after the activated carbon particles 11 have been used for a long time, it is convenient for the user to open the purification shell 32 to maintain the filter frame 33 and the activated carbon particles 11. The exhaust pipe 35 can discharge the air purified by the activated carbon particles 11 to the outside.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, the drying mechanism 4 includes a fixed plate 41, several semiconductor heating plates 42, several ventilation holes 43, an air inlet pipe 44, a fan 45, an air duct 46, a PLC controller 47, and a temperature sensor 48. The fixed plate 41 is welded to the bottom of the inner side of the drying shell 2.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the semiconductor heating plate 42 is installed on the top of the fixed plate 41, the ventilation hole 43 is opened on the inner side of the fixed plate 41, the air inlet pipe 44 is fixedly connected to the front side of the drying shell 2, the fan 45 is fixedly connected to the front side of the top of the workbench 1, and the air duct 46 is fixedly connected to the front side of the air inlet pipe 44.

[0032] Specifically, such as Figure 4 , Figure 5As shown, the front side of the air duct 46 is fixedly connected to the rear side of the fan 45, the PLC controller 47 is installed on the right side of the drying shell 2, the temperature sensor 48 is installed on the left side of the drying shell 2, and the detection end of the right side of the temperature sensor 48 penetrates through the drying shell 2 and extends to the inside of the drying shell 2.

[0033] In this embodiment: the fixed plate 41 can support and limit the semiconductor heating plate 42 and the ventilation hole 43. The semiconductor heating plate 42 can heat the air at the bottom inside the drying shell 2. The ventilation hole 43 allows the air delivered by the air inlet pipe 44 to pass through and drive the hot air upward. The air inlet pipe 44 can guide the air generated by the fan 45 to the bottom inside the drying shell 2. The fan 45 forms a hot air closed loop through the air duct 46 and the air inlet pipe 44, shortening the drying time. The flared design of the air duct 46 reduces the air intake resistance and allows the air to enter the air inlet pipe 44 evenly. The PLC controller 47 can receive the data detected by the temperature sensor 48 and control the power of the semiconductor heating plate 42 and the fan 45. At the same time, it can control the speed of the servo motor 8. The temperature sensor 48 can monitor the temperature inside the drying shell 2 in real time and transmit the data to the PLC controller 47.

[0034] Specifically, such as Figure 5 As shown, reinforcing rods 9 are fixedly connected to both sides of the fan 45, and the side of the reinforcing rod 9 away from the fan 45 is fixedly connected to the top of the workbench 1.

[0035] Specifically, such as Figure 6 As shown, the conveyor belt 7 is configured as a filter mesh, and the surface of the conveyor belt 7 is coated with an anti-corrosion coating.

[0036] In this embodiment: by setting the reinforcing rod 9, the vibration generated by the fan 45 during operation is effectively dispersed, preventing the fan 45 from shifting or loosening due to vibration, reducing the probability of equipment failure, and extending the service life of the fan 45. By setting the conveyor belt 7 as a filter screen, the filter screen structure allows hot air to contact the material from the underside of the conveyor belt 7. By setting the anti-corrosion coating, the corrosive chemicals volatilized during the drying process can easily corrode the conveyor belt 7. The anti-corrosion coating can effectively resist the corrosion of these substances and extend the service life of the conveyor belt 7.

[0037] Specifically, such as Figure 6 As shown, the front right side of the conveyor belt 7 is connected to the connecting shaft 10 via a flat key, and the output end of the servo motor 8 on the left side passes through the support plate 6 and is fixedly connected to the right side of the connecting shaft 10.

[0038] Specifically, such as Figure 3 As shown, the surface of the filter frame 33 is set as a mesh, and the inner side of the filter frame 33 is filled with activated carbon particles 11.

[0039] In this embodiment: By setting the connecting shaft 10 as the connection hub between the servo motor 8 and the conveyor belt 7, the rotational power of the servo motor 8 is reliably transmitted to the conveyor belt 7, ensuring the smooth operation of the conveyor belt 7. By setting the surface of the filter frame 33 to be a mesh, exhaust gas can be allowed to pass through the filter frame 33 and come into contact with the activated carbon particles 11. By setting the activated carbon particles 11, the activated carbon has a rich pore structure and a huge specific surface area, which has a strong adsorption capacity for odor gases generated during the drying process.

[0040] Working Principle: First, the operator places the material to be dried and cured on the conveyor belt 7. Then, the operator controls the servo motor 8 to start via the PLC controller 47. The servo motor 8 drives the conveyor belt 7 through the connecting shaft 10. The material enters the equipment from the inlet / outlet 5 on the front side of the drying shell 2. Next, the PLC controller 47 controls the semiconductor heating plate 42 to start working, heating the air at the bottom inside the drying shell 2. At the same time, the fan 45 introduces external air through the air duct 46 and the air inlet pipe 44, driving the hot air upward through the ventilation hole 43, forming a hot air circulation inside the drying shell 2, realizing the heating and drying of the material. Then, the exhaust gas generated during the drying process is guided to the purification shell 32 through the exhaust shell 31. The filter frame 33, which is made of mesh, is in full contact with the activated carbon particles 11 filled inside. The activated carbon particles 11 adsorb odor gases and volatile organic compounds in the exhaust gas. At the same time, the temperature sensor 48 monitors the temperature inside the drying shell 2 in real time and transmits the data to the PLC controller 47. The PLC controller 47 controls the power of the semiconductor heating plate 42 and the fan 45 according to the preset program and the detection data, and adjusts the speed of the servo motor 8 to adapt to the drying process requirements of different materials. Finally, the air purified by the activated carbon particles 11 is discharged to the outside through the exhaust pipe 35, completing the exhaust gas treatment. The dried and solidified material is sent out of the equipment from the rear inlet and outlet 5 by the conveyor belt 7. The user can then take out the dried and solidified material.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
