Specific implementation mode

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and the implementation mode.

[0024] Please refer to Figures 1 to 6 , a filter facilitating screen replacement includes a filter body 1, a box door 2 is rotatably installed on the front surface of the filter body 1, a feed pipe 3 is installed on the top of the filter body 1, a discharge pipe 4 is installed on the bottom of the filter body 1, a screen 5 is movably installed inside the filter body 1 through a sliding mechanism 6, a disassembly mechanism 11 is movably arranged on the top of the screen 5, a working chamber 8 is formed inside the rear side of the filter body 1, an adjusting mechanism 9 is received inside the working chamber 8, a moving mechanism 7 is arranged at the intersection of the adjusting mechanism 9 and the disassembly mechanism 11, and a driving mechanism 10 is arranged at the driving end of the adjusting mechanism 9.

[0025] During use, when it is necessary to disassemble the screen 5, first drive the driving motor 101 so that the driving rotating shaft 102 can rotate. The adjusting gear 91 installed on the outer wall of the end of the driving rotating shaft 102 will rotate synchronously inside the working chamber 8 as the driving rotating shaft 102 rotates. At this time, two adjusting racks 92 symmetrically engaged on the upper and lower sides of the adjusting gear 91 will move horizontally left and right, so that two moving slide plates 72 respectively installed at the front ends of the two adjusting racks 92 will move synchronously inside the two moving chutes 71 as the two adjusting racks 92 move, until the two clamping blocks 112 respectively installed at the front ends of the two moving slide plates 72 are respectively moved out of the two filter bodies 1. Then, the screen 5 is moved and disassembled from the inside of the filter body 1 through the sliding cooperation between the slide bar 62 and the slide rail 61, thereby realizing the convenient and rapid disassembly of the screen 5, facilitating the disassembly work of the staff on the screen 5, and improving the filtering effect and efficiency of the filter body 1.

[0026] During the specific implementation process, such as Figure 1 and Figure 3As shown, the driving mechanism 10 includes a driving motor 101 installed on the outer wall of the rear side of the filter body 1. A driving rotating shaft 102 is fixed to the driving end of the driving motor 101. One end of the driving rotating shaft 102 away from the driving motor 101 rotatably extends into the interior of the working chamber 8 and is connected to the front inner wall of the working chamber 8 by a bearing at the end.

[0027] During use, the provided driving motor 101 prepares for the subsequent rotation of the driving and adjusting mechanism 9, and the driving rotating shaft 102 is installed on the driving end of the driving motor 101. When the driving motor 101 operates, the driving rotating shaft 102 will be able to rotate in both the forward and reverse directions below, preparing for the subsequent left and right movement of the disassembly mechanism 11.

[0028] Reference Figure 3 and Figure 4 As shown, the adjusting mechanism 9 includes an adjusting gear 91 fixedly sleeved on the outer surface of the driving rotating shaft 102, and the adjusting gear 91 is inside the working chamber 8.

[0029] During use, the adjusting gear 91 is installed on the outer wall of the driving rotating shaft 102. When the driving rotating shaft 102 rotates, the adjusting gear 91 will also rotate accordingly.

[0030] Reference Figure 4 As shown, adjusting racks 92 are symmetrically meshed and connected to the upper and lower sides of the adjusting gear 91, and both of the two adjusting racks 92 are inside the working chamber 8.

[0031] During use, the two adjusting racks 92 are symmetrically meshed on the upper and lower sides of the adjusting gear 91. When the adjusting gear 91 rotates, the two adjusting racks 92 will move horizontally back and forth in the up and down directions of the adjusting gear 91 along with the rotation of the adjusting gear 91, and the two adjusting racks 92 will move horizontally closer to each other or away from each other.

[0032] Reference Figure 1 As shown,

[0033] Reference Figure 5 and Figure 6 As shown, the adjusting mechanism 9 further includes adjusting slide rails 93 symmetrically fixed to the upper and lower inner walls of the working chamber 8. Adjusting sliders 94 are slidably connected to the interiors of the two adjusting slide rails 93, and the outer wall of one end of the adjusting slider 94 away from the adjusting slide rail 93 is connected to the adjusting rack 92.

[0034] During use, through the sliding fit between the adjusting slide rail 93 and the adjusting slider 94, the meshing movement between the adjusting rack 92 and the adjusting gear 91 is made more stable, and the situation where one end of the adjusting rack 92 drops off will not occur.

[0035] ReferenceFigure 2 and Figure 5 As shown in Figure 5 and , the moving mechanism 7 includes moving chutes 71 symmetrically and oppositely formed on the rear inner wall of the filter body 1. A moving slide plate 72 is movably arranged inside each of the two moving chutes 71. One end of the moving slide plate 72 inside the working chamber 8 is connected to the adjusting rack 92.

[0036] During use, one end of the moving slide plate 72 is connected to the adjusting rack 92. When the adjusting rack 92 moves horizontally as the adjusting gear 91 rotates, the moving slide plate 72 will also move synchronously inside the moving chute 71 following the movement of the adjusting rack 92.

[0037] Reference Figure 5 and Figure 6 As shown in Figure 5 and Figure 6 , the disassembly mechanism 11 is provided with a clamping groove 111 on the outer wall of one side of the slide rail 61 and the slide rod 62. The clamping groove 111 is close to the rear inner wall of the filter body 1.

[0038] Reference Figure 5 As shown in Figure 5 , a clamping block 112 is clamped inside the clamping groove 111. One end of the clamping block 112 away from the clamping groove 111 is connected to the moving slide plate 72.

[0039] During use, the clamping block 112 is connected to the moving slide plate 72. When the moving slide plate 72 moves horizontally along with the adjusting rack 92, the clamping block 112 can be moved out of the inside of the clamping groove 111, so that the fixed state between the slide rail 61 and the slide rod 62 is opened, enabling the screen 5 to be slid out and disassembled from the inside of the box door 2 through the sliding between the slide rod 62 and the slide rail 61. Conversely, moving the clamping block 112 and clamping it into the inside of the clamping groove 111 can fix the sliding state of the slide rail 61 and the slide rod 62, preventing the screen 5 from sliding back and forth inside the filter body 1.

[0040] The working principle of a filter for facilitating the replacement of the screen provided by the present utility model is as follows:

[0041] When the screen mesh 5 needs to be disassembled, first drive the drive motor 101 so that the drive rotating shaft 102 can rotate. The adjusting gear 91 installed on the outer wall of the end of the drive rotating shaft 102 will rotate synchronously inside the working chamber 8 as the drive rotating shaft 102 rotates. At this time, the two adjusting racks 92 symmetrically meshed on the upper and lower sides of the adjusting gear 91 will move horizontally left and right, so that the two moving slide plates 72 respectively installed at the front ends of the two adjusting racks 92 will move synchronously inside the two groups of moving chutes 71 as the two adjusting racks 92 move, until the two clamping blocks 112 respectively installed at the front ends of the two moving slide plates 72 are respectively removed from the inside of the two groups of filter bodies 1. Then, the screen mesh 5 is disassembled from the inside of the filter body 1 through the sliding fit between the sliding rod 62 and the sliding rail 61, thereby realizing the convenient and rapid disassembly of the screen mesh 5, facilitating the disassembly work of the staff on the screen mesh 5, and improving the filtering effect and efficiency of the filter body 1.
