Description

Technical Field

[0001] The utility model relates to an air filter, in particular to a cooling air filter, and belongs to the technical field of cooling filtering equipment. Background Art

[0002] Some chemical products are added in the paper production process. When the paper sheets pass through the high temperature of the drying section, these chemical products and paper scraps will stick to the dry net. These paper scraps are mixed with chemical products to form adhesives that adhere to the dry net. The adhesives attached to the dry net are cleaned by online cleaning. The online cleaning system uses 5MP pressure water to flush the dry net from the back. During the cleaning process, the cleaning nozzle has a water receiving bucket that runs synchronously with the nozzle. The water receiving bucket is connected to the vacuum fan, and the vacuum fan is coaxially connected to the impeller. The high-speed rotation of the impeller forms a negative pressure greater than -0.2MP, and the washed adhesives are sucked out to the storage tank to clean the adhesives on the dry net.

[0003] During the operation of the vacuum fan, the gap between the fan impeller and the shell is very small. If adhesives are brought into the rotating impeller area, the impeller will be stuck, which will cause the motor to overload. In addition, the vacuum fan is frequently started at full power frequency, which will cause the motor insulation to decrease. In addition, the hot air in the drying cylinder sucked out by the vacuum fan will also cause the motor temperature to rise, causing the vacuum fan to malfunction and affect its use.

[0004] Therefore, there is an urgent need for an improved cooling air filter to solve the above-mentioned problems. Utility Model Content

At the same time, a cooling water pipe 9 is also arranged on the filter screen 7. Injecting coolant into the cooling water pipe 9 can cool the inhaled hot air to prevent the vacuum fan 1 from overheating and causing failure to affect the use.

[0025] A fixing sleeve 10 is fixedly installed on the water inlet and water outlet ends of the cooling water pipe 9 extending to the outside of the fixed pipe 5, and a sleeve 11 connected by a thread is provided on the fixed sleeve 10. A plurality of push rods 12 are evenly fixedly installed on the surface of the sleeve 11, and the surface of the push rods 12 is provided with anti-slip grooves. Two electric telescopic rods 13 are symmetrically installed on the surface of the fixed pipe 5, and a support rod 14 extending to the inside of the filter 7 is fixedly installed on the output end of the electric telescopic rod 13, and a push plate 15 connected to the support rod 14 is provided inside the filter 7. By setting the fixing sleeve 10 and the sleeve 11, it is convenient to connect the water inlet and outlet of the cooling water pipe 9 with the external pipeline. After the external pipeline is docked on the water inlet and outlet of the cooling water pipe 9, the sleeve 11 is rotated to move it along the thread on the fixing sleeve 10 to the external pipeline, so that the sleeve 11 is combined with the thread on the external pipeline, and the cooling water pipe 9 and the external pipeline are connected and fixed. It is convenient to use and is strong enough. By setting the push rod 12, it is convenient to push the sleeve 11 to rotate and move. By setting the electric telescopic rod 13, the support rod 14 and the push plate 15, the two electric telescopic rods 13 are started at the same time to extend their output ends to drive the support rod 14 to rise.

Through the arrangement of the positioning block 20, since the positioning block 20 is conical in shape, the diameter of the bottom is smaller than the diameter of the top, so that the positioning rod 19 can be more easily inserted into the positioning block 20, which is convenient for use.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a cooling air filter provided in this embodiment is as follows:

[0028] A fixed pipe 5 is arranged on the air inlet pipe 2, and a filter screen 7 is arranged inside the fixed pipe 5. The inhaled gas and adhesives enter the filter screen 7 through the air inlet 6. The filter screen 7 can block and filter the adhesives to prevent the adhesives from entering the vacuum blower 1. At the same time, a cooling water pipe 9 is also arranged on the filter screen 7. Infusing coolant into the cooling water pipe 9 can cool the inhaled hot air to prevent the vacuum blower 1 from overheating and causing a malfunction that affects its use.

[0029] In summary, in this embodiment, according to a cooling air filter of this embodiment, the water inlet and outlet ends of the cooling water pipe 9 are conveniently connected to the external pipeline through the setting of the fixing sleeve 10 and the sleeve 11. After the external pipeline is docked on the water inlet and outlet ends of the cooling water pipe 9, the sleeve 11 is rotated to move it along the thread on the fixing sleeve 10 to the external pipeline, so that the sleeve 11 is combined with the thread on the external pipeline, and the cooling water pipe 9 and the external pipeline can be connected and fixed, which is convenient to use and firm enough. Through the setting of the push rod 12, it is convenient to push The movable sleeve 11 rotates and moves, and through the arrangement of the electric telescopic rod 13, the support rod 14 and the push plate 15, the two electric telescopic rods 13 are started at the same time to extend their output ends to drive the support rod 14 to rise. When the support rod 14 rises, the push plate 15 in the filter 7 is pulled. The push plate 15 rises and can eject the adhesives filtered and retained in the filter 7, thereby facilitating the cleaning of the inside of the filter 7. Through the arrangement of the flange 16 and the bolts 17, the fixed pipe 5 as a whole can be tightly connected to the intake pipe 2 to prevent it from falling off, and through the fixed block 18. The arrangement of the positioning rod 19 and the positioning block 20, before installing and connecting the fixing pipe 5 and the intake pipe 2, can position the fixing pipe 5 by inserting the positioning rod 19 into the positioning block 20, so that the threaded holes on the two flanges 16 can be accurately aligned, and it is convenient to insert the bolts 17 for fixing. Through the arrangement of the positioning block 20, since the positioning block 20 is conical in shape, the diameter of the bottom is smaller than the diameter of the top, so that the positioning rod 19 can be more easily inserted into the positioning block 20, which is convenient for use.
