[0027] The filter screen replacement device of the dust collector is used for replacing the filter screen body 12 in the dust collector body 11 after a period of use, and when the filter screen body 12 is installed in the dust collector body 11, the arc-shaped plate 13 is naturally arranged at the bottom side of the filter screen body 12 due to the design of the arc-shaped plate 13 on the inner wall of the dust collector body 11, and the mounting hole of the dust collector body 11 is in a matching form with the filter screen body 12, so that the arc-shaped plate 13 is tightly embedded in the dust collector body 11 by exerting an external force, and the arc-shaped plate 13 is designed with a horizontal rod 14 at the bottom side, and the horizontal rod 14 is integrated with the arc-shaped plate 13, and then the handle 110 on the dust collector body 11 is rotated by 90 degrees, and the angle of the movable arm 15 is changed in the process, and the movable arm 15 is finally in a vertical state, and the horizontal rod 14 is subjected to an external force when the movable arm 15 changes, and the horizontal rod 14 is moved in the original position due to the design of the horizontal rod 14 in two or more forms, so that the arc-shaped plate 13 gradually contacts the filter screen body 12, and the filter screen body 12 is tightly matched with the dust collector body 11, and the operator only needs to rotate the handle 110 on the dust collector body 11 to easily replace the filter screen, and the design avoids the complex disassembly steps in the traditional filter screen replacement process.

[0028] In the process of changing the movable arm 15, a connecting rod 16 is designed on one side of the horizontal rod 14, and the connecting rod 16 can slide on the horizontal rod 14, so that the connecting rod 16 is subjected to an external force to one side when the movable arm 15 changes, and one end of the connecting rod 16 is provided with a supporting rod 17, and the supporting rod 17 is in an inclined state when the connecting rod 16 is not moved, and the supporting rod 17 gradually becomes vertical when the connecting rod 16 moves, so as to provide support for the horizontal rod 14 from the end position, and further increase the tightness of the connection between the filter screen body 12 and the dust collector body 11, and ensure that the filter screen body 12 is stably installed in the dust collector body 11 in the vibration environment generated by the high-load operation of the dust collector or in the complex air flow impact;

[0029] Before rotating the handle 110, the limiting block 111 needs to be moved from one side of the handle 110, and after the 90-degree rotation is completed, the external force on the limiting block 111 is released, and the internal spring 112 is elastically released to push the limiting block 111 back, and then the limiting block 111 naturally corresponds to the recess hole on the handle 110 and enters the handle 110, so as to keep the position of the handle 110 after rotation unchanged, and ensure that all components are in a stable state;

[0030] Secondly, the arc-shaped plate 13 is provided with a side plate 19 on one side, when the arc-shaped plate 13 is in contact with the filter screen body 12, the side plate 19 is naturally located at the end of the filter screen body 12, avoiding the movement of the filter screen body 12 in the dust collector body 11, and ensuring that the position of the filter screen body 12 is always in a stable form.

[0031] Finally, the dust collector body 11 is designed with a conveying pipe 116 on one side, which is connected by welding, the other end of the conveying pipe 116 is installed with a fan 115, and belongs to a communication state, so when the fan 115 is running, a negative pressure environment will be formed inside the dust collector body 11, according to Bernoulli's principle, the pressure is inversely proportional to the flow rate when the gas flows, the negative pressure environment makes the air flow rate in the factory building accelerate, so as to suck the dust-containing air into the dust collector body 11.

[0032] Embodiment 2: please refer to Figure 5 The auxiliary mechanism 2 includes an inner block 21, the inner block 21 is provided with a spring piece two 22 on one side, the inner block 21 is fixedly connected with one end of the spring piece two 22, the other end of the spring piece two 22 is fixedly connected with the inner wall of the cross rod 14, the inner wall of the cross rod 14 is slidingly connected with the outer side of the inner block 21, and one end of the inner block 21 is fixedly connected with one side of the connecting rod 16.

[0033] When the movable arm 15 no longer causes external force to the connecting rod 16, since the inner block 21 is installed on the top side of the connecting rod 16, the inner block 21 can move in the cross rod 14 in a synchronous manner, once the external force disappears, the spring piece two 22 on one side of the inner block 21 will reset the connecting rod 16 by using the self-retraction, the automatic reset function can quickly make the equipment return to the initial state during the continuous filter screen replacement operation, and prepare for the next filter screen installation and fixation, effectively shorten the operation interval time, and the design of the inner block 21 ensures that the connecting rod 16 slides along the specified path when moving, avoiding the path deviation.

[0034] Please refer to Figures 1-6When the filter screen body 12 is installed in the dust collector body 11, because the arc-shaped plate 13 is designed on the inner wall of the dust collector body 11, and the arc-shaped plate 13 is naturally located at the bottom side of the filter screen body 12 when the filter screen is located in the dust collector body 11, because the mounting hole of the dust collector body 11 and the filter screen body 12 belong to the fitting form, at this time, in order to enable the arc-shaped plate 13 to tightly embed the filter body in the dust collector body 11 in the manner of exerting external force, first, the horizontal rod 14 is designed on the bottom side of the arc-shaped plate 13, and the two belong to an integral, and then, by rotating the handle 110 on the dust collector body 11 by 90 degrees, the movable arm 15 changes the angle in the process, and the movable arm 15 finally presents a vertical state, and the movable arm 15 changes to cause external force to the horizontal rod 14, so that the horizontal rod 14 moves on the original position, and then the arc-shaped plate 13 gradually contacts the filter screen body 12, so that the filter screen body 12 and the dust collector body 11 are tightly fitted, because the connecting rod 16 is designed on one side of the horizontal rod 14, the connecting rod 16 can slide on the horizontal rod 14, therefore, with the change of the movable arm 15, not only the external force is caused to the horizontal rod 14 upward or downward, but also the external force is caused to the connecting rod 16 to one side, at this time, one end of the connecting rod 16 is provided with the supporting rod 17, the supporting rod 17 is in an inclined state when the connecting rod 16 is not moved, and the supporting rod 17 gradually becomes a vertical state with the movement of the connecting rod 16, so as to provide support ability for the horizontal rod 14 from the end position, before rotating the handle 110, the limiting block 111 needs to be moved from one side of the handle 110, and after completing the 90-degree rotation, the external force on the limiting block 111 is released, and the elastic sheet 112 in the inside is elastically released to top the limiting block 111 back, and then the limiting block 111 naturally corresponds to the recess hole on the handle 110 and enters the handle 110, so as to keep the position of the handle 110 after rotation unchanged.

[0035] Because the inner block 21 is installed on the top side of the connecting rod 16, the inner block 21 can slide in the horizontal rod 14 in a synchronous manner when the connecting rod 16 moves, and once the external force disappears, the elastic sheet 22 on one side of the inner block 21 will reset the connecting rod 16 by using the retraction of itself, and the automatic reset function can quickly make the equipment return to the initial state when continuously replacing the filter screen, so as to prepare for the next filter screen installation and fixation.
