At the same time, by setting the installation component 11, the second filter screen 13 inside the ventilation pipe 5 can be quickly installed and disassembled, so as to facilitate the cleaning of the first filter screen 7 and the second filter screen 13 more conveniently. At the same time, the exhaust fan 9 is mainly turned on and off through the console.

[0030] Sliding blocks 1006 are symmetrically installed on both sides of the connecting sleeve 1005. Sliding grooves 1007 are symmetrically opened on both sides of the through groove 1003. The sliding grooves 1007 are slidably connected to the sliding blocks 1006. A first spring 1008 is sleeved on one side of the surface of the support rod 1004 near the bottom. The bottom surface of the first spring 1008 is fixedly connected to a pressing plate 1009. The top surface of the first spring 1008 is fixedly connected to the connecting plate 1002.

[0031] Installation components 11 are symmetrically arranged on both sides of the ventilation pipe 5. The installation component 11 includes a sliding rod 1101 fixedly connected to the ventilation pipe 5. The surface of the sliding rod 1101 is penetrated and connected with a sliding plate 1102. A stabilizing plate 1103 is fixedly connected to one side surface of the sliding plate 1102 near the top. A limiting rod 1104 is penetrated and connected to the side surface of the stabilizing plate 1103 away from the sliding plate 1102. A second spring 1105 is sleeved on one side of the surface of the limiting rod 1104 near the bottom. The bottom surface of the second spring 1105 is fixedly connected to a fitting plate 1106. The top surface of the second spring 1105 is fixedly connected to the stabilizing plate 1103. The bottom surface of the fitting plate 1106 is in fit connection with the sliding rod 1101. The fitting plate 1106 is penetrated and connected with the limiting rod 1104. A plurality of limiting grooves 1107 are opened on the top surface of the sliding rod 1101. The limiting grooves 1107 are engaged with the limiting rod 1104. As Figure 4 、 5As shown, by pulling the limit rod 1104 again, after the limit rod 1104 is separated from the limit slot 1107 again, by pushing the sliding plate 1102, the sliding plate 1102 slides on the sliding rod 1101. After the sliding plate 1102 slides a certain distance, one side of the sliding plate 1102 penetrates through the ventilation pipe 5, and one side of the sliding plate 1102 is located above the second filter screen 13, so that the sliding plate 1102 can limit and stabilize the second filter screen 13. After the sliding plate 1102 limits the second filter screen 13, by loosening the limit rod 1104, the limit rod 1104 descends under the action of the second spring 1105, so that the limit rod 1104 is re-engaged with the limit slot 1107, thus completing the installation of the second filter screen 13, so that the second filter screen 13 can also filter dust. At the same time, the second spring 1105 is a rubber composite spring in the prior art, and the rubber composite spring has a large elastic force.

[0032] Chutes 12 are symmetrically opened inside the ventilation pipe 5. A second filter screen 13 is slidably connected inside the chutes 12. A block 14 is attached to the bottom surface of the second filter screen 13. One side surface of the block 14 is fixedly connected to the ventilation pipe 5. The sliding plate 1102 is away from the stabilizing plate 1103 and passes through one side surface of the ventilation pipe 5 and is attached to the second filter screen 13, as Figure 4 、 5 shown. Through the action of the chutes 12 and the block 13, it is convenient to take out the second filter screen 13 from the inside of the ventilation pipe 5 for cleaning.

[0033] The first filter screen 7 is connected through the air outlet pipe 4. As Figure 3 shown, a gasket is provided between the first filter screen 7 and the air outlet pipe 4 to prevent air leakage between the first filter screen 7 and the air outlet pipe 4.

[0034] Working principle: Before using this ring roller mill that is convenient for heat dissipation, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 5As shown in the figure, when the first filter screen 7 needs to be disassembled and cleaned, by rotating the support rod 1004, the support rod 1004 can drive the rotation of the connecting sleeve 1005 and the sliding block 1006, so that the sliding block 1006 rotates inside the circular sliding groove 1007. After rotating the support rod 1004 by 90°, the pressing plate 1009 can be driven to rotate by 90°, so that the pressing plate 1009 no longer limits and presses the first filter screen 7, so that the staff can pull out the first filter screen 7. At the same time, a sealing gasket is provided between the first filter screen 7 and the air outlet pipe 4 to avoid air leakage between the first filter screen 7 and the air outlet pipe 4. When installing the cleaned first filter screen 7, after passing the first filter screen 7 through the air outlet pipe 4 and making the first filter screen 7 snap into the card slot 6, by rotating it 90° in the reverse direction, the pressing plate 1009 fits with the first filter screen 7 again, thus completing the limiting function of the first filter screen 7, improving the installation and disassembly efficiency of the first filter screen 7, and also better filtering dust. At the same time, through the action of the exhaust fan 9, the inside of the body 2 can be assisted in heat dissipation.

[0035] Secondly, when it is necessary to clean the second filter screen 13, by pulling the limit rod 1104, after the limit rod 1104 is separated from the limit groove 1107, by pulling the sliding plate 1102, the sliding plate 1102 slides on the sliding rod 1101. After the sliding plate 1102 slides a certain distance, one side of the sliding plate 1102 is separated from the second filter screen 13. By loosening the limit rod 1104, the limit rod 1104 descends under the action of the second spring 1105, so that the limit rod 1104 is re-engaged with the limit groove 1107, thereby limiting the sliding plate 1102. At the same time, when the sliding plate 1102 is separated from the second filter screen 13, the staff can take out the second filter screen 13 inside the ventilation pipe 5, so that the second filter screen 13 can be cleaned. At the same time, when installing the cleaned second filter screen 13, after placing the second filter screen 13 on the chute 12 inside the ventilation pipe 5, the second filter screen 13 descends due to its own gravity. When the second filter screen 13 descends a certain distance, the stop block 14 limits the second filter screen 13. At the same time, by pulling the limit rod 1104 again, after the limit rod 1104 is separated from the limit groove 1107 again, by pushing the sliding plate 1102, the sliding plate 1102 slides on the sliding rod 1101. After the sliding plate 1102 slides a certain distance, one side of the sliding plate 1102 penetrates through the ventilation pipe 5, so that one side of the sliding plate 1102 is located above the second filter screen 13, so that the sliding plate 1102 can limit the second filter screen 13 stably. After the sliding plate 1102 limits the second filter screen 13, by loosening the limit rod 1104, the limit rod 1104 descends under the action of the second spring 1105, so that the limit rod 1104 is re-engaged with the limit groove 1107, thus completing the installation of the second filter screen 13, so that the second filter screen 13 can also filter dust.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described 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 invention shall be included in the protection scope of the present invention.
