Description

Technical Field

[0001] This utility model relates to a quick filter replacement device, specifically a quick filter replacement device for screening equipment, belonging to the technical field of screening equipment. Background Technology

[0002] In industrial production, screening equipment is a key component widely used for material grading and impurity removal. Its core working part—the filter screen—directly determines screening efficiency, product quality, and equipment operational stability. Under the long-term effects of material impact, friction, corrosion, and mechanical vibration, the filter screen inevitably experiences wear, blockage, deformation, and even breakage. This leads to decreased screening accuracy, reduced processing capacity, and increased energy consumption, ultimately affecting the continuity of the production line and product quality.

[0003] Currently, most screening equipment filters are either directly fixed to the equipment or secured with bolts. This requires manual disassembly of the components or loosening of the bolts one by one, which is time-consuming and results in prolonged downtime for the screening equipment, affecting screening efficiency.

[0004] Therefore, a quick filter replacement device for screening equipment is proposed here. Utility Model Content

[0018] Please refer to this carefully. Figure 2 and Figure 4The main body 1 of the screening equipment has a placement groove 103 on its surface. A fixing plate 307 is installed inside the placement groove 103. A moving rod 306 is fixed to the lower surface of the fixing plate 307. The main body 1 of the screening equipment has a second movable chamber 104 and a third movable chamber 105. The third movable chamber 105 is located below the placement groove 103. The lower end of the moving rod 306 is vertically inserted into the third movable chamber 105. A fixing groove 308 is installed on the upper surface of the fixing plate 307. The fixing groove 308 corresponds to the second connecting rod 304. A second spring 309 is sleeved on the outer periphery of the moving rod 306. The two ends of the second spring 309 are respectively fixed to the inner wall of the placement groove 103 and the fixing plate. 307 lower surface; the fixing assembly 3 also includes a top rod 312 passing through the second movable chamber 104, the moving rod 306 has a groove 310 on its side, the other end of the top rod 312 passes through the third movable chamber 105 and has an inclined surface corresponding to the groove 310, one end of the top rod 312 is engaged in the groove 310, a baffle 311 is fixed on the surface of the moving rod 306, a third spring 313 is sleeved on the outer periphery of the top rod 312, the two ends of the third spring 313 are respectively fixed to the inner wall of the second movable chamber 104 and the side of the top rod 312, the end of the top rod 312 near the filter screen 2 has an inclined surface, and the top rod 312 and the moving rod 306 are perpendicular to each other.

[0019] The third spring 313 is in a stretched state when the filter screen 2 is installed, and the second spring 309 is in a compressed state when the filter screen 2 is installed.

[0020] When using this utility model: First, install the device at the designated position on the main body 1 of the screening equipment. When it is necessary to disassemble the filter screen 2, the operator only needs to pull the second connecting rod 304 to both sides. The second connecting rod 304 drives the first connecting rod 303 fixed at both ends to move. The first connecting rod 303 drives the limiting rod 302 fixed at its lower end to move, so that one end of the limiting rod 302 retracts into the first movable chamber 101. After the filter screen 2 is no longer restricted by the limiting rod 302, under the reaction of the fourth spring 503, the telescopic rod 501 and the top plate 502 can push the filter screen 2 upward. Then, the operator pulls the handle 4 to remove the filter screen 2 from the main body 1 of the screening equipment.

[0021] When the filter screen 2 is pushed upward by the telescopic rod 501, the fourth spring 503 and the top plate 502, the filter screen 2 is no longer restricted to the top rod 312. Under the rebound force of the third spring 313, the top rod 312 is moved, causing one end of the top rod 312 to disengage from the inclined groove 310, thereby removing the restriction on the moving rod 306. Subsequently, under the rebound force of the second spring 309, the moving rod 306 and the fixing block fixed at the top of the moving rod 306 are pushed upward, so that the second connecting rod 304 is engaged in the fixing groove 308 opened on the surface of the fixing block.

[0022] When the filter screen 2 needs to be installed, the operator only needs to push the filter screen 2 downwards using the handle 4. When the filter screen 2 contacts the top rod 312, the filter screen 2 can push the top rod 312 to move because the top rod 312 has an inclined surface near the filter screen 2. Also, because the top rod 312 has an inclined surface corresponding to the inclined groove 310 at the end near the moving rod 306, and the top rod 312 and the moving rod 306 are perpendicular, the top rod 312 can drive the moving rod 306 to move downwards during its movement inside the inclined groove 310. This causes the fixing block fixed at the top of the moving rod 306 to move downwards synchronously, causing the second connecting rod 304, which is locked inside the fixing groove 308, to disengage and remove the restriction on the second connecting rod 304. Then, under the rebound force of the first spring 305, the limiting rod 302 can be pushed to move, pushing one end of the limiting rod 302 out of the first movable chamber 101 and locking it onto the upper surface of the filter screen 2 to limit the filter screen 2.
