Description

Technical Field

[0001] The utility model relates to the technical field of preheating machines, in particular to a preheating machine provided with a dust-proof structure. Background Art

[0002] Preheating machines are usually used to increase the temperature of materials during subsequent processing, so as to reduce energy consumption and improve processing performance. In some environments or usage scenarios, preheating machines require a dust-proof structure to ensure the long-term stable operation of the equipment and materials, and reduce failures and pollution caused by dust.

[0003] After retrieval, a high-frequency preheating machine with a dust-proof structure with the publication number CN216087053U, specifically related to the field of high-frequency preheating machines, includes a preheating machine body. The upper surface and one side surface of the preheating machine body are fixedly installed with heat dissipation ports, and a slider is slidably connected inside the slide rail. When the utility model is in normal use, first remove the heat dissipation port on the top surface of the preheating machine body, then grind out a fixing groove according to the size of the first dust-proof net, and then put the first dust-proof net into the fixing groove from top to bottom. When the first dust-proof net enters the fixing groove, it will squeeze the insertion block to move towards the inside of the chute. When the insertion block and the limiting groove are at the same horizontal line, it will pop out and lock the first dust-proof net for positioning. At the same time, when the insertion block is squeezed, the slider will slide inside the slide rail to ensure the balance of the insertion block. When the first dust-proof net needs to be disassembled and cleaned, only need to hold the moving block and slide to release the positioning of the insertion block and then take out the first dust-proof net.

[0004] Based on the above patent, by setting the first dust-proof net, the preheating machine body can have a dust-proof effect, and it is also convenient to disassemble for cleaning and replacement. When the device is in normal use, first remove the heat dissipation port on the top surface of the preheating machine body, then grind out a fixing groove according to the size of the first dust-proof net, and then put the first dust-proof net into the fixing groove from top to bottom. When the first dust-proof net enters the fixing groove, it will squeeze the plug block to move inside the chute. When the plug block and the limiting groove are at the same horizontal line, it will pop out and lock the first dust-proof net for positioning. At the same time, when the plug block is squeezed, the slider will slide inside the slide rail to ensure the balance of the plug block. When the first dust-proof net needs to be disassembled and cleaned, just hold the moving block and slide it to release the limit of the plug block and then take out the first dust-proof net. By setting the heat dissipation fan and the adhesion mesh cloth, the preheating machine body can quickly clean the scattered ash that drifts into the interior of the preheating machine body while dissipating heat. When the first dust-proof net is dust-proof, the heat dissipation fan can be driven to dissipate heat from top to bottom. While the heat dissipation fan is blowing, in order to prevent dust from entering the heat dissipation fan, a metal frame is installed on the front and back sides of the heat dissipation fan. At the same time, a second dust-proof net is fixedly connected in the gap of the metal frame. Finally, when the heat dissipation fan is blowing, part of the scattered ash floating in the interior of the preheating machine body can be blown onto the adhesion mesh cloth on the bottom surface of the preheating machine body. However, when using the heat dissipation fan to filter dust in the air and using the filter screen to filter particulate matter in the air in this patent, when large particulate dust in the air is on the filter screen, it will block the filter screen, thereby affecting the air dust filtering effect of the device, resulting in insufficient air flow kinetic energy of the preheating machine and affecting the preheating effect and operation efficiency.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 1-6, an embodiment provided by the present utility model: a preheating machine with a dust-proof structure, including a device housing 1, a switching plate 2 is rotatably connected to the rear side of the top end of the device housing 1, a connecting door 3 is rotatably connected to the left front side of the device housing 1, a preheating table 4 is fixedly connected to the inner wall of the device housing 1, a preheating module 5 is fixedly connected to the top end of the preheating table 4. In the device, the preheating module 5 can preheat the material to perform temperature treatment on the material. When the cooling fan 8 is started, the temperature inside the device is reduced. A conveying module 6 is fixedly connected to the rear end of the inner wall of the device housing 1, a fixing plate 7 is fixedly connected to the top end of the inner wall of the device housing 1, and a connecting shell 9 is fixedly connected to the middle of the top end of the fixing plate 7.

[0028] Referring to Figure 3 and Figure 4 , dust discharge channels 11 are fixedly connected to the front, back, left, and right ends of the fixing plate 7. Swirl tubes 12 are fixedly connected to the top ends of the dust discharge channels 11. Opposite ends of the outer walls of the swirl tubes 12 are fixedly connected to and penetrate through deflection ventilation pipes 13. After the deflection ventilation pipes 13 enter the swirl tubes 12, spiral airflows are generated, thereby generating centrifugal force on the airflows. Connecting tubes 14 are fixedly connected to and penetrate through the top ends of the swirl tubes 12. Worm wheel blades 15 are fixedly connected to the driving ends of the front and back of the bidirectional drive motor 10. When the bidirectional drive motor 10 is started, the worm wheel blades 15 rotate, and the worm wheel blades 15 rotate and suck air from the spiral offset holes at the swirl hole blocks 16. Swirl hole blocks 16 are fixedly connected to the bottom ends of the inner walls of the swirl tubes 12, allowing large-particle dust to flow from the inner wall near the swirl tubes 12 into the swirl hole blocks 16 and flow out from the dust discharge channels 11. After the cooling fan 8 generates wind force, the connecting tubes 14 suck the air in the swirl tubes 12 that has already discharged dust to the filter screen 17 for secondary filtration. Opposite ends of the dust discharge channels 11 corresponding to the bottom end of the fixing plate 7 are respectively fixedly connected to and penetrate through the left and right ends of the inner wall of the device housing 1. Opposite ends of the deflection ventilation pipes 13 corresponding to the top end of the fixing plate 7 are respectively fixedly connected to the left and right ends of the inner wall of the device housing 1. Opposite ends of the connecting tubes 14 are respectively fixedly connected to and penetrate through the front, back, left, and right sides of the left and right ends of the connecting shell 9. The outer walls of the worm wheel blades 15 are rotatably connected to the inner wall of the top end of the dust discharge channels 11, enabling the device to fully filter the dust in the inhaled air, thereby improving the dust filtering effect of the device, reducing the pollution and damage of dust to the equipment and materials, extending the service life of the equipment, and avoiding blockage of the filter screen 17 by large-particle dust, thereby extending the filtering time limit of the device.

[0029] Referring to Figure 5 and Figure 6, dust filter nets 17 are installed at both the left and right ends of the inner wall of the connection shell 9. The rear side of the top end of the connection shell 9 is rotatably connected to an installation door 18. The front end of the connection shell 9 is fixedly connected to a chute block 20. The front end of the installation door 18 is fixedly connected to a docking block 19. A clamping block 22 is slidably connected to the inner wall of the docking block 19 through a return spring 21. When the dust filter net 17 needs to be replaced, the clamping block 22 is toggled to compress the return spring 21. The top end of the return spring 21 is fixedly connected to the top end of the inner wall of the docking block 19, and the bottom end of the return spring 21 is fixedly connected to the top end of the clamping block 22, so that the clamping block 22 falls off from the chute block 20, enabling the installation door 18 to be opened within the connection shell 9 and replacing the dust filter nets 17 installed on both sides of the connection shell 9. The bottom outer wall of the clamping block 22 is detachably connected to the inner wall of the chute block 20 to ensure the filtering effect of the device. The continuously ensured filtering effect enables the device to operate under optimal conditions, reducing additional energy consumption and reducing performance degradation or failures caused by dust blockage.

[0030] Working principle: The preheating module 5 in the device can preheat the material to perform temperature treatment on the material. When the cooling fan 8 is started, it cools the temperature inside the device. When the bidirectional drive motor 10 is started to rotate the worm wheel blade 15, the worm wheel blade 15 rotates and sucks air from the spiral offset hole of the swivel hole block 16. After the air enters the swirl tube 12 through the deflecting ventilation pipe 13, a spiral air flow is generated, thereby generating a centrifugal force for the air flow, allowing large-particle dust to flow into the swivel hole block 16 from the inner wall near the swirl tube 12 and flow out from the dust discharge channel 11. After the cooling fan 8 generates wind power, the connecting pipe 14 sucks the air with dust already discharged from the upper layer of the swirl tube 12 to the dust filter net 17 for secondary filtration, enabling the device to fully filter the dust in the inhaled air, thereby improving the dust filtering effect of the device, reducing the pollution and damage of dust to the equipment and materials, extending the service life of the equipment, and avoiding blockage of the dust filter net 17 by large-particle dust, thereby extending the filtering time limit of the device. When the dust filter net 17 needs to be replaced, the clamping block 22 is toggled to compress the return spring 21, so that the clamping block 22 falls off from the chute block 20, enabling the installation door 18 to be opened within the connection shell 9 and replacing the dust filter nets 17 installed on both sides of the connection shell 9, thereby ensuring the filtering effect of the device. The continuously ensured filtering effect enables the device to operate under optimal conditions, reducing additional energy consumption and reducing performance degradation or failures caused by dust blockage.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
