Description

Technical Field

[0001] This utility model relates to the technical field of powder shaking machines, and in particular to a smoke removal device and a powder shaking machine. Background Technology

[0002] The white ink heat transfer process mainly includes steps such as designing the pattern, printing, sprinkling and shaking the powder, heating, and transferring the pattern. In this process, the powder shaking machine is responsible for evenly sprinkling the hot melt powder onto the printed heat transfer film, and ensuring that the pattern is firmly bonded to the fabric through the powder shaking and heating steps.

[0003] The powder-shaking machine includes an oven and a smoke removal device. The powder-shaking machine evenly sprinkles hot melt powder onto the heat transfer film through vibration, and then shakes off the excess hot melt powder by releasing the film. The hot melt powder is on the heat transfer film and enters the oven of the powder-shaking machine as the heat transfer film moves. The heat transfer film and the hot melt powder on the film are heated, and the hot melt powder melts into the heat transfer film. The heat transfer film is then transferred to the clothing by pressing.

[0004] When an oven heats the heat transfer film and the hot melt powder inside the film, the hot melt powder generates oil fumes during the heating process. In existing technology, existing fume extraction devices include a housing and a liquefaction plate. The housing has a receiving cavity, and the liquefaction plate is housed in the receiving cavity and liquefies the oil fumes therein, outputting a portion of the oil and filtered fumes. Existing fume extraction devices only liquefy the oil fumes through the liquefaction plate, resulting in poor fume extraction efficiency. Utility Model Content

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] Please refer to the attached document. Figures 1-6 This application provides a smoke removal device 100, which is applied to a dust collector. The smoke removal device 100 is used to liquefy and electrolyze oil fumes in order to discharge clean gas to the external environment.

[0044] Please refer to the attached document. Figures 1-6In this embodiment, the smoke removal device 100 includes a housing 10, a liquefaction module 20, an electric field module 30, and a fan 40. The housing 10 is provided with a receiving cavity 10a and an oil fume inlet 10b. The oil fume inlet 10b is connected to the receiving cavity 10a and is used to allow oil fumes to enter. The liquefaction module 20 is housed within the receiving cavity 10a. The liquefaction module 20 includes multiple liquefaction elements 21, which are arranged sequentially along the length of the receiving cavity 10a. The oil fumes flow within the receiving cavity 10a and pass sequentially through the multiple liquefaction elements 21, so that the oil fumes are liquefied upon contact with the liquefaction elements 21, thereby outputting a portion of the oil and filtered oil fumes. The electric field module 30 is disposed within the liquefaction module 20. On one side, the electric field module 30 is provided with a honeycomb electric field 31, and the honeycomb electric field 31 is provided with a gas channel 31a. The gas channel 31a is used for the flow of filtered oil fumes. During the flow of the filtered oil fumes in the gas channel 31a, electrolysis is performed to output clean gas. The fan 40 is housed in the receiving cavity 10a and draws in the clean gas output by the honeycomb electric field 31. The exhaust end of the fan 40 is used to discharge the clean gas to the external environment of the housing 10, so that the oil fumes can be liquefied and electrolyzed by the liquefaction module 20 and the electric field module 30, thereby realizing the discharge of clean gas to the external environment, avoiding the oil fumes from polluting the external environment, and improving the smoke removal effect of the smoke removal device 100.

[0045] Please refer to the attached document. Figures 1-6 In this embodiment, the housing 10 serves as a support for the smoke removal device 100, supporting the liquefaction module 20, the electric field module 30, and the fan 40. The housing 10 has a receiving cavity 10a and an oil fume inlet 10b. The receiving cavity 10a serves as the internal space of the housing 10; the oil fume inlet 10b connects to the receiving cavity 10a and is used to allow oil fumes to enter, facilitating the entry of oil fumes into the receiving cavity 10a via the oil fume inlet 10b.

[0046] The liquefaction module 20 is housed within the receiving cavity 10a to fully utilize the internal space of the receiving cavity 10a. The liquefaction module 20 includes multiple liquefaction components 21, which are arranged sequentially along the length of the receiving cavity 10a. The fumes flow within the receiving cavity 10a and pass through the multiple liquefaction components 21 in sequence, so that the fumes are liquefied upon contact with the liquefaction components 21, thereby outputting a portion of the oil and filtered fumes. This ensures the liquefaction effect of the fumes by using multiple liquefaction components 21 to achieve liquefaction.

[0047] The electric field module 30 is located on the right side of the liquefaction module 20. The electric field module 30 is equipped with a honeycomb electric field 31, which is equipped with a gas channel 31a. The gas channel 31a is used to supply the filtered oil fume for flow. The filtered oil fume is electrolyzed during the flow of the gas channel 31a, so that the filtered oil fume can be electrolyzed through the honeycomb electric field 31, ensuring the electrolysis effect of the filtered oil fume and outputting clean gas.

[0048] The fan 40 is housed in the housing cavity 10a and draws in clean gas output through the honeycomb electric field 31. The exhaust end of the fan 40 is used to discharge the clean gas to the external environment of the housing 10 so that the oil fume can be liquefied and electrolyzed by the liquefaction module 20 and the electric field module 30, thereby achieving the discharge of clean gas to the external environment, avoiding the oil fume from polluting the external environment, and improving the smoke removal effect of the smoke removal device 100.

[0049] Please refer to the attached document. Figures 1-5 In this embodiment, the multiple liquefaction components 21 include a first partition 211. Multiple first partitions 211 are arranged along the width of the housing 10 and relative to the fume inlet 10b. Fumes entering through the fume inlet 10b pass through the multiple first partitions 211 and are liquefied upon contact with them. The arrangement of multiple first partitions 211 increases the contact area between the fumes and the first partitions 211, allowing more fume particles to simultaneously contact and liquefy with the first partitions 211. At this time, the temperature of the first partitions 211 is lower than the temperature of the fumes, so that the low-temperature surface of the first partitions 211 can rapidly cool the oil mist particles in the fumes upon contact with the partitions. When the temperature drops below the dew point of the oil mist, the oil mist particles liquefy, thus achieving the liquefaction effect of the first partitions 211 on the fumes.

[0050] Please refer to the attached document. Figures 2-5 In this embodiment, the first partition 211 has multiple air passages 211a arranged in an array for the passage of oil fumes. The smoke removal device 100 also includes a fan 50, which is located at the end of the housing 10 facing away from the fan 40. The fan 50 is installed in the housing 10, with its input end connected to the external environment and its output end facing the multiple first partitions 211. The gas output from the fan 50 cools the first partitions 211, making their temperature lower than that of the oil fumes. This increases the cooling efficiency of the first partitions 211 relative to the oil fumes, facilitating the rapid cooling and liquefaction of oil mist particles in the oil fumes. Simultaneously, the array arrangement of the multiple air passages 211a allows the gas to flow evenly through all parts of the first partitions 211, preventing localized overheating or underheating and achieving a more uniform cooling effect.

[0051] Please refer to the attached document. Figures 2-5 In this embodiment, the multiple liquefaction components 21 include a metal mesh 212, which is disposed on one side of the first partition 211. The oil fumes pass through the first partition 211 and the metal mesh 212 in sequence and are liquefied in sequence. This allows the first partition 211 and the metal mesh 212 to cooperate in liquefying the oil fumes simultaneously, thereby improving the liquefaction efficiency of the oil fumes. The filtered oil fumes discharged through the metal mesh 212 enter the gas channel 31a of the honeycomb electric field 31, so that the filtered oil fumes can be transferred to the gas channel 31a, thereby facilitating the electrolysis of the filtered oil fumes during the flow of the gas channel 31a.

[0052] Please refer to the attached document. Figures 1-3 In embodiment 6, the gas channel 31a has multiple channels arranged in an array and facing the same metal mesh 212; so that the multiple gas channels 31a arranged in an array can make the oil fume gas evenly distributed, increase the contact area between the oil fume and the honeycomb electric field 31, thereby improving the electrolysis efficiency.

[0053] The honeycomb electric field 31 generates a high-voltage electrostatic field during operation. The filtered oil fumes undergo electrolysis under the influence of this field, producing clean gas. During this process, the oil fume gas is ionized by the high-voltage electrostatic field, and the oil mist particles become charged. These charged particles move towards the electrode with the opposite charge under the influence of the electric field, thus achieving the electrolysis effect. Optionally, the voltage of the honeycomb electric field 31 is 15000V.

[0054] Please refer to the attached document. Figures 1-3 In embodiment 6 of this application, the input end of the fan 40 faces each gas channel 31a, and the output end of the fan 40 is connected to the external environment. When the fan 40 is in operation, it draws clean gas output through the honeycomb electric field 31 so that the clean gas output by the honeycomb electric field 31 can be discharged to the external environment through the fan 40, so as to output clean gas to the external environment.

[0055] Please refer to the attached document. Figure 1 and 3 In this embodiment of the application, the housing 10 is provided with a first oil drain pipe 10c. The input end of the first oil drain pipe 10c is connected to the receiving cavity 10a and is located below the first partition 211. The output end of the first oil drain pipe 10c is located below the housing 10 and is used to drain the oil dripping through the first partition 211, so that the oil dripping through the first partition 211 can flow from top to bottom through the receiving cavity 10a and the first oil drain pipe 10c to the external environment, thereby achieving the effect of draining the oil dripping through the first partition 211.

[0056] Please refer to the attached document. Figure 1 and 3In this embodiment, the housing 10 is provided with a second oil drain pipe 10d. The input end of the second oil drain pipe 10d is connected to the receiving cavity 10a and is located below the metal mesh 212. The output end of the second oil drain pipe 10d is located below the housing 10 and is used to drain the oil dripping from the metal mesh 212. This allows the oil dripping from the metal mesh 212 to flow downwards through the receiving cavity 10a and the second oil drain pipe 10d to the external environment, thereby achieving the effect of draining the oil dripping from the metal mesh 212. The second oil drain pipe 10d is connected to the first oil drain pipe 10c so that the oil can be discharged to the external environment along both the second oil drain pipe 10d and the first oil drain pipe 10c, ensuring the effective drainage of the oil.

[0057] In the second embodiment of the application, a powder shaker includes an oven and a smoke removal device 100. The smoke removal device 100 is part of the powder shaker, and it is connected to the oven to process the oil fumes output from the oven.

The liquefaction module 20 includes multiple liquefaction elements 21, which are arranged sequentially along the length of the receiving cavity 10a. Oil fumes flow within the receiving cavity 10a and pass sequentially through the multiple liquefaction elements 21, causing the oil fumes to liquefy upon contact with the liquefaction elements 21, thereby outputting a portion of the oil and filtered oil fumes.
