Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter bag structure of a filter that is easy to replace. Background Art

[0002] A Chinese patent discloses a bag filter (publication number: CN216537305U). The device drives the connecting rod to rotate downward by pressing the push rod, and then pushes the movable plate to squeeze the spring through the connecting rod. When the movable plate moves outward, the telescopic rod contracts. The movable plate moves outward and drives the fixed rod and the positioning block to move outward together, so that the positioning block is separated from the positioning groove. After both positioning blocks are separated from the positioning groove, the filter bag can be taken out downward, so that the filter bag drives the plug block to take out the interface from the slot for replacement, avoiding excessive debris accumulation in the filter bag. However, the following problems may occur during the use of the device:

[0003] There are two positioning blocks for supporting and fixing the filter frame, which are respectively placed on both sides of the filter bag device. Therefore, when removing the filter bag, the operator needs to press the push rod downward at the same time. At this time, the positioning blocks on both sides are separated from the positioning grooves, and the filter frame equipped with the filter screen will lose support and fall onto the filter plate under the influence of gravity, which may cause the filtered material inside the filter screen to leak out and cause the filter plate to be blocked, and it is also more troublesome to recover the filter screen;

[0004] In addition, the filter plate in the device should be kept clean at all times during the use of the device. If the filter plate is clogged somewhere and is not cleaned in time, the filtration efficiency may be reduced due to the blockage of the filter plate. For this reason, a filter bag structure that is easy to replace for the filter machine is proposed to solve the above problem. Utility Model Content

[0005] The technical problems to be solved by the utility model are as follows:

[0006] When the operator uses the device, he presses the push rod downward at the same time. At this time, the positioning blocks on both sides are separated from the positioning grooves. The filter frame equipped with the filter mesh will lose its support and then fall onto the filter plate under the influence of gravity, which makes it more troublesome to recover the filter mesh. The filter plate in the device should be kept clean at all times during the use of the device. If the filter plate is blocked somewhere and is not cleaned in time, the filtration efficiency may be reduced due to the blockage of the filter plate.

[0036] The working principle of this utility model:

[0037] When the filter bag 202 of the device needs to be replaced, the operator first pulls the pull ring 105 to pull up the top cover 103 and separate it from the device housing 101. At this time, the operator holds the grips 203 on both sides with both hands and presses the control button 204 downward. When the control button 204 descends, the bottom inclined surface pushes the fixing pin 119. The fixing pin 119 is subjected to a horizontal force and moves away from the contact head 205. When the bottom end of the control button 204 is engaged with the middle groove of the contact head 205, the operator holds the grips 203 on both sides and lifts them up. At this time, there is no object blocking the contact head 205, and the support frame 201 can be separated from the support block 108.

[0038] Secondly, after replacing the filter bag 202, reset the top cover 103, insert the material pipe from the inside of the pipe opening 106, and start the motor 114. The output end of the motor 114 drives the turntable 115 to rotate. At this time, the push shaft 116 pushes the inner wall of the connecting frame 117, thereby driving the cleaning brush 118 to brush above the filter plate 109, and push the blockage above the filter plate 109 to above the guide plate 110. At this time, open the flip plate 111 regularly to push the blockage into the collection box 112 for subsequent centralized recovery.

[0039] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
