Description
Technical Field
[0001] The utility model relates to the technical field of filter press unloading, in particular to a filter press unloading device. Background Art
[0002] A filter press is a device that uses filter plates to squeeze to achieve solid-liquid separation. Filter cloths are laid on both sides of the filter plates, and the filter plates are pressed by a pressing device to form filter chambers between the filter plates. During the filtration process, the slurry enters each filter chamber under the push of a feed pump, and solid-liquid separation is achieved through the filter cloth. The solid particles remain in the filter chamber to form a filter cake, while the filtrate passes through the filter cloth and is discharged from the liquid outlet, thereby achieving the purpose of solid-liquid separation.
[0003] Currently, in the operation of the filter press, during the unloading stage, since the filter cakes are compacted relatively tightly, they fall from the filter press onto the conveyor belt in a large block structure. This compact block structure is prone to blockage during the transportation of the conveyor belt. Once blockage occurs, the staff is required to immediately shut down the machine for processing. The shutdown not only prolongs the unloading time of the filter press and reduces production efficiency, but also requires the staff to manually break the filter cake when dealing with the blockage. This processing method is not only labor-intensive, but also cumbersome in the operation process, which increases labor costs. Therefore, it is necessary to provide a filter press unloading device to solve the above technical problems. Utility Model Content
[0004] The purpose of the utility model is to provide a filter press unloading device to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A filter press unloading device comprises a filter press, a placing frame and a crushing assembly, wherein the placing frame is arranged below the filter press, a conveyor belt is fixedly installed on the top of the placing frame, a limiting bucket is installed inside the placing frame, the crushing assembly is fixedly installed inside the limiting bucket, the crushing assembly comprises a mounting seat, two mounting seats are symmetrically fixedly installed at two ends of the limiting bucket, two groups of sliding rods are symmetrically and slidably connected inside the limiting bucket, one end of the two groups of sliding rods passes through the side wall of the limiting bucket respectively and is sleeved with springs, one end of the two groups of sliding rods are fixedly installed with an extrusion seat, one end of the spring is fixedly connected to one side of the extrusion seat, and the side of the spring away from the extrusion seat is in extrusion contact with the side wall of the limiting bucket.
[0007] A further improvement of the technical solution of the utility model is that: currently in the operation of the filter press, during the unloading stage, since the filter cakes are compacted more tightly, they fall from the filter press onto the conveyor belt in a large block structure. This compact block structure is prone to blockage during the transportation of the conveyor belt. Once blockage occurs, the staff is required to immediately shut down the machine for processing. The shutdown not only prolongs the unloading time of the filter press and reduces production efficiency, but also requires the staff to manually break the filter cake when dealing with the blockage. This processing method is not only labor-intensive, but also cumbersome in the operation process, increasing the labor cost. In the present solution, when the filter press needs to be unloaded, the filter cake falls from the filter press at this time, falls onto the crushing assembly through the limiting bucket, and at the same time, the crushing assembly works synchronously to crush the large block-shaped filter cake through the crushing assembly, breaks the filter cake into small pieces, and then falls onto the conveyor belt and is transported out through the conveyor belt.
[0008] The above technical solution is adopted, in which the top end of the limiting bucket is symmetrically inclined.
[0009] A further improvement of the technical solution of the utility model is that the inclination setting of the limiting bucket top can guide the filter cake discharged from the filter press in a standardized manner, so that the filter cake can stably enter the crushing component for the crushing component to crush the filter cake.
[0010] The above technical solution is adopted, in which the two mounting seats are diagonally arranged at the two ends of the limiting bucket.
[0011] A further improvement of the technical solution of the utility model is that the diagonally arranged mounting seats facilitate the installation of the crushing components, so that the crushing components can cooperate with each other when working, further improving the crushing effect.
[0012] The above technical solution is adopted, in which the end of the mounting seat is symmetrically provided with mounting grooves that are rotatably matched with the cam.
[0013] A further improvement of the technical solution of the utility model is that the mounting groove at the end of the mounting seat can increase the mounting stability of the cam, thereby making the operation of the cam more stable.
[0014] The above-mentioned technical scheme is adopted, and the crushing assembly in this scheme also includes a mounting rod, and the two mounting rods are respectively rotatably connected to the end of the two mounting seats away from the limiting bucket, and two cams are symmetrically fixedly installed on the two mounting rods, and a working motor is fixedly installed on one side of the two mounting seats, and the output ends of the two working motors pass through the side walls of the mounting seats and are respectively fixedly connected to one end of the two mounting rods, and a plurality of mounting plates are equidistantly fixedly installed on one side of the two groups of sliding rods, and a plurality of matching plates are equidistantly fixedly installed on the other side of the two groups of sliding rods, and crushing vertical plates are fixedly installed on the tops of the plurality of mounting plates.
[0015] A further improvement of the technical solution of the utility model is that when the filter cake falls onto the crushing assembly, the block-shaped filter cake will directly contact the crushing vertical plate, and the filter cake will be preliminarily crushed by the crushing vertical plate. At the same time, the working motor starts to work, and the working motor drives the mounting rod to rotate. As the mounting rod rotates, the mounting rod drives the cam to perform circular motion. As the cam performs regular circular motion, the cam will periodically squeeze the extrusion seat, and the extrusion seat is fixedly connected to the end of the sliding rod. As the extrusion seat is squeezed, the sliding rod will move a distance. At the same time, the extrusion seat will compress the spring when it is squeezed. Under the elastic force of the spring, the extrusion seat always fits against the outer ring of the cam, and can drive the sliding rod to reset. As the sliding rod moves, the mounting plate and the matching plate arranged on one side of the sliding rod will periodically be plugged and matched, so as to further crush the filter cake.
[0016] The above technical solution is adopted, in which a vertical rod is provided on one side of a plurality of the crushing vertical plates, and the bottom ends of the plurality of vertical rods are fixedly connected to the upper surface of the sliding rod.
[0017] A further improvement of the technical solution of the utility model is that the arrangement of the vertical rod can increase the connection strength between the crushing vertical plate and the sliding rod, so that the crushing vertical plate is more stable and more convenient to use when crushing the filter cake.
[0018] The above technical solution is adopted, in which the top end of the vertical rod is arranged in a conical shape.
[0019] A further improvement of the technical solution of the utility model is that the vertical rod of the conical design is convenient for cooperating with the crushing vertical plate to crush the filter cake.
[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0021] 1. The utility model provides a filter press unloading device. Through the setting of the crushing component, large block filter cakes can be quickly crushed to prevent the occurrence of blockage. In addition, the crushing component adopts a combination design of spaced mounting plates and matching plates, which can make the crushed filter cakes further broken and refined when passing through these spaced plates, greatly improving the crushing effect. Such a design not only improves the crushing efficiency, but also makes the unloading work of the filter press more convenient and efficient.
[0022] 2. The utility model provides a filter press unloading device, which can cooperate with each other through symmetrically arranged crushing components. The filter cakes that fall onto the crushing components can be directly crushed through the crushing vertical plates, and can also be squeezed against each other through the symmetrically arranged structures. After the filter cakes are initially crushed, the crushing effect of the filter cakes is further refined through the mutual squeezing of the crushing vertical plates, ensuring that the filter cakes are crushed more thoroughly. The setting of the crushing components not only improves the crushing efficiency, but also enhances the crushing effect, thereby greatly facilitating the subsequent unloading work of the filter press.

At the same time, the crushing assembly works synchronously to crush the large block-shaped filter cakes through the crushing assembly, breaking the filter cakes into small pieces, which then fall onto the conveyor belt 3 and are transported out through the conveyor belt 3.
