Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a high-efficiency pulling plate component used for separating filter cakes of a filter press. Background Art

[0002] The filter press uses a special filter medium and is widely used in municipal environmental protection, food and beverage, chemical pharmaceuticals, petrochemicals, printing and dyeing, papermaking and other related industrial industries. The filter plate and filter cloth are the filter elements of the filter press. After the filter plates are pressed tightly, they form a filter chamber. During filtration, the filter cloth intercepts the solid particles in the material and forms a filter cake in the filter chamber. The filtrate passes through the filter cloth and discharges from the filter chamber to achieve solid-liquid separation. When the filter press is unloading, the trolley pulls the filter plates apart one by one along the track. After the filter plates are pulled apart, the filter cake inside falls from the filter plates.

[0003] When the existing filter press performs a plate pulling operation after completing filtration, the plate pulling mechanism can only pull open one filter plate each time it reciprocates, which reduces the efficiency of the plate pulling. Utility Model Content

[0039] Slide grooves are bored on both sides of the interior of the fixed sleeve 202, and the slider 203 is embedded in the slide grooves and slidably connected to the slider 203. A spring 204 is arranged at the bottom of the slider 203, so that the spring 204 provides an upward elastic force to the slider 203, so that the slider 203 can move up and down inside the fixed sleeve 202. An inclined surface is arranged at one end of the slider 203, and a hook claw 205 is arranged at the top of the inclined surface. A groove is arranged on one side of the hook claw 205, so that the hook claw 205 can be connected with the limit column 301 arranged inside the limit block 3.

[0040] Embodiment 3

[0041] See also Figure 3 , Figure 4 and Figure 5 , the utility model provides a technical solution: an efficient pulling plate assembly for separating filter cakes of a filter machine, comprising a limiting block 3, a limiting column 301, a guiding block 302 and a filling block 303;

[0042] A limiting column 301 is arranged inside the limiting block 3. The limiting column 301 is cylindrical and is arranged horizontally in a groove excavated inside the limiting block 3. A guide block 302 is arranged at the front end of the limiting block 3. A notch is arranged in the middle of the guide block 302. A filling block 303 is arranged at the end of the limiting block 3. The size of the filling block 303 is consistent with the size of the notch in the middle of the guide block 302. There are several limiting blocks 3, and several limiting blocks 3 are arranged on both sides of the filter plate 103. The slider 203 can be driven to move by the transmission of the pulling plate part 2, so that the slider 203 abuts against the limiting column 301, thereby driving the limiting block 3 to move. The guide block 302 is slidably connected to the inclined surface set at one end of the slider 203, and the slider 203 can slide along the guide block 302 through the set inclined surface. During the filtration, multiple filter plates 103 are connected and squeezed together front to back. At this time, the filling block 303 and the gap set at the front end of the slider 203 can be assembled together to form a plane. Guide frames 4 are set on both sides of the clamping plate 102. The structure of the guide frame 4 is consistent with the structure of the front end of the guide block 302, so that the guide frame 4 can also be slidably connected to the slider 203, and assembled with the filling block 303 at the end of a limit block 3 in front of the clamping plate 102.

[0043] Working principle: First, the cylinder provided at one end of the filter press 1 provides power to drive the pressing plate 102 to slide on the slide rail 101, and squeeze a number of filter plates 103 between the stop plate 104 and the pressing plate 102 to complete the filter pressing operation. Then the cylinder controls the pressing plate 102 to move back. At this time, the motor on one side of the pulling plate part 2 is started to drive the transmission chain 201 in the pulling plate part 2 to rotate unidirectionally, which can drive the fixed sleeve 202 to move. The slider 203 inside the fixed sleeve 202 will be pushed by the spring 204. The filter plates 103 are connected together front and back, so that the limit blocks 3 are connected end to end, thereby pressing the slider 203 and preventing it from popping out. When the slider 203 moves to the side of the filter plate 103 at the front end, the slider 203 receives the elastic force of the spring 204 and slides upward, so that the hook 205 set on one side of the slider 203 is stuck and driven to operate, thereby completing the plate pulling operation, and the slider 203 on the transmission chain 201 will pull the filter plates 103 apart in turn, thereby improving the efficiency of the plate pulling.

[0044] Secondly, when the filter plate 103 is driven to the side of the clamping plate 102, the guide frame 4 set on the side of the clamping plate 102 will push the slider 203 to move down along the fixed sleeve 202, so that it retracts into the fixed sleeve 202, thereby allowing the hook 205 to disengage from the limit column 301, and the next slider 203 will be pushed by the guide block 302 set on the side of the previous filter plate 103, so that the filter plates 103 hooked by the hook 205 can be unlocked in turn, thereby facilitating the filter press 1 to complete the next filtration operation.
