Abstract
Description
Technical Field
[0001] This utility model applies to the field of filter press technology, and in particular relates to an automatic unloading filter press. Background Technology
[0002] Currently, a filter press is a mechanical device that uses a special filter medium to apply a certain pressure to the object, causing the liquid to seep out. It is a commonly used solid-liquid separation device.
[0003] However, in current filter presses used for pressure filtration of slurry, solid impurities mixed in with the slurry accumulate on the outside of the filter screen under pressure. After filtration, the filter screens cannot automatically return to their original position and stick together under pressure. Consequently, the solid impurities accumulated on the outer wall of the filter screens cannot be cleaned quickly and promptly. The operator must manually remove the filter screens to clean the accumulated impurities, a time-consuming and labor-intensive process that reduces overall processing efficiency. Therefore, we propose an automatic unloading filter press. Utility Model Content
[0004] The main objective of this invention is to provide an automatic unloading filter press that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An automatic unloading filter press includes two sets of mounting plates. A grouting pipe is fixedly installed between the tops of the two sets of mounting plates. A guide rod is fixedly installed between the middle of the two ends of the side of the two sets of mounting plates. An installation frame is slidably installed between the outer sides of the two sets of guide rods. The number of installation frames is several sets. A filter screen is fixedly installed at both ends of the outer side of each installation frame.
[0007] Electric slide rails are fixedly installed on both sides of the mounting plate. A pushing mechanism is provided on the outer side of each electric slide rail, and the pushing mechanism is connected to the outer side of the mounting frame through a transmission.
[0008] An air injection mechanism is provided between the bottom of the mounting plate, and the air injection mechanism is connected to the inside of the mounting frame.
[0009] As an optional solution to the technical solution of this application, the pushing mechanism includes a limiting baffle and a reset torsion spring. Each of the electric slide rails is driven to a movable frame on its outer side. A fixed plate is installed on both sides of the top of the movable frame. A rotating rod is rotatably installed on the middle of the side of the fixed plate through a bearing. A limiting baffle is fixedly sleeved on the middle of the outer side of the rotating rod. A hollow frame is fixedly installed on the outer side of the fixed plate. A transmission rod is rotatably installed inside the hollow frame. The top of the side of the transmission rod and the top of the side of the rotating rod are fixedly connected. A reset torsion spring is movably sleeved on the outer side of each transmission rod. The two ends of the side of the reset torsion spring respectively abut against the outer side of the transmission rod and the inner side wall of the hollow frame.
[0010] By adopting the above technical solution, under the transmission action of the transmission rod, after the mounting frame moves horizontally, the limiting baffle can be provided with corresponding pressure force, and after it rotates, the return torsion spring can be provided with corresponding torsional force. This allows the limiting baffle to rotate and return to its original position after the external pressure force disappears, ensuring that the limiting baffle can abut against the mounting frame and make it move horizontally when the moving frame moves horizontally.
[0011] As an optional solution to the technical solution of this application, a fixed sleeve is fixedly sleeved on the side of the guide rod near the push plate, and a pressing block is fixedly installed on the outer side of each fixed sleeve. A sliding sleeve is slidably sleeved on the outer side of the guide rod, and the outer side of the sliding sleeve is fixedly connected to the outer side of the mounting frame. A push block is fixedly installed at the middle of the outer side of each sliding sleeve, and the bottom surface of the push block and the pressing block and the top surface of the limiting baffle are on the same horizontal plane.
[0012] By adopting the above technical solution, with a push block connected to the outside of the mounting frame and a pressing block provided at the top of the guide rod side, the limiting baffle can be provided with corresponding pressing force during the horizontal movement of the mounting frame, thereby allowing the limiting baffle to rotate and drive the mounting frame to move horizontally, thereby causing the two adjacent sets of mounting frames to move horizontally and separate from each other.
[0013] As an optional solution to the technical solution of this application, a connecting plate is fixedly installed at the bottom center of each mounting plate, an air blowing pipe is fixedly installed between the middle of the two sets of connecting plates, a fixed pipe is fixedly connected to the top of the air blowing pipe vertically, a corrugated hose is fixedly connected to the top of each fixed pipe, and the corrugated hose is fixedly connected to the bottom of the mounting frame, a connecting pipe is fixedly connected to the top of the side of the air blowing pipe, and exhaust holes are opened on both sides inside each mounting frame, and the number of exhaust holes is several sets, with the exhaust holes located between the inner sides of the two sets of filters.
[0014] By adopting the above technical solution, the mounting frame and the air blowing pipe are connected through a corrugated hose, so that the external air pump operates to pressurize and deliver the gas into the air blowing pipe. The gas can then be discharged from the inside of the mounting frame, and air can be blown from the side of the filter screen to separate the solid impurities adsorbed and accumulated on its surface, thereby further improving the cleaning efficiency of solid impurities adsorbed on the outside of the filter screen.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. An automatic unloading filter press according to the technical solution of this application, wherein a movable frame is slidably arranged on the outside of the mounting plate, and rotatable limiting baffles are arranged on both sides of the top of the movable frame, so that when the movable frame moves horizontally driven by the electric slide rail, the limiting baffle on one side of the top of the movable frame is pressed by a pushing block connected to the outside of the mounting frame, and rotates downward. As the movable frame continues to move to the right, the pushing block can move out from the top of the limiting baffle and loses the pressing force on the limiting baffle. Then, the movable frame is driven to the left. Under the blocking action of the limiting baffle on the right side, the movable frame can drive a single set of mounting plates. The frame and filter screen move synchronously to the left, allowing them to automatically separate. Then, under the pressure of the pressing block and the left-side cleaning push block, the limiting baffle on the top left of the moving frame remains in a downward rotating state. After cleaning a single set of mounting frames and its surface filter screen, the moving frame continues to move to the right, and the mounting frame and its side pressing block automatically move away from the top of the moving frame. This allows the moving frame to continuously drive subsequent mounting frames, facilitating the automatic pushing and separating of mounting frames that are stuck together, and thus facilitating the cleaning of solid impurities on the outside of the mounting frames.
[0017] 2. An automatic unloading filter press according to the technical solution of this application has an air blowing pipe at the bottom of the mounting plate, and the air blowing pipe is connected to the exhaust hole on the inner wall of the mounting frame through a corrugated hose at the bottom of the mounting frame. After the external air pump is operated to pressurize and deliver the gas into the air blowing pipe, the gas can be discharged from the inside of the mounting frame under the connecting and conveying action of the corrugated hose. Then, the gas can be blown from the side of the filter screen to blow away and separate the solid impurities adsorbed and accumulated on its surface, thereby further improving the cleaning efficiency of solid impurities adsorbed on the outside of the filter screen.

[0022] like Figure 1-3 As shown, this utility model provides a technical solution: an automatic unloading filter press, wherein a grouting pipe 15 is fixedly installed between the top of two sets of mounting plates 1, a guide rod 11 is fixedly installed between the middle of the two ends of the side of the two sets of mounting plates 1, and a mounting frame 12 is slidably installed between the outer sides of the two sets of guide rods 11, and the number of mounting frames 12 is several sets, and a filter screen 13 is fixedly installed at both ends of the outer side of each mounting frame 12.
[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), electric slide rails 2 are fixedly installed on both sides of the mounting plate 1. Each electric slide rail 2 is connected to a moving frame 21 on its outer side. Each moving frame 21 is fixedly installed on both sides of its top. A rotating rod 23 is rotatably installed on the middle side of the fixed plate 22 via a bearing. A limit baffle 24 is fixedly sleeved on the middle side of the rotating rod 23. A hollow frame 25 is fixedly installed on the outer side of the fixed plate 22. A transmission rod 26 is rotatably installed inside the hollow frame 25. The top side of the transmission rod 26 is fixedly connected to the top side of the rotating rod 23. A return torsion spring 27 is movably sleeved on the outer side of each transmission rod 26. The two ends of the return torsion spring 27 abut against the outer side of the transmission rod 26 and the inner side wall of the hollow frame 25, respectively.
[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a fixed sleeve 3 is fixedly sleeved on the side of the guide rod 11 near the push plate 14. A pressing block 31 is fixedly installed on the outside of each fixed sleeve 3. A sliding sleeve 32 is slidably sleeved on the outside of the guide rod 11, and the outside of the sliding sleeve 32 is fixedly connected to the outside of the mounting frame 12. A pushing block 33 is fixedly installed at the middle of the outside of each sliding sleeve 32, and the bottom surface of the pushing block 33 and the pressing block 31 is on the same horizontal plane as the top surface of the limiting baffle 24.
[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a connecting plate 4 is fixedly installed at the bottom center of each mounting plate 1. An air blowing pipe 41 is fixedly installed between the middle of the two sets of connecting plates 4. A fixed pipe 45 is fixedly connected vertically to the top of the air blowing pipe 41. A corrugated hose 43 is fixedly connected to the top of each fixed pipe 45. The corrugated hose 43 is fixedly connected to the bottom of the mounting frame 12. A connecting pipe 42 is fixedly connected to the top of the side of the air blowing pipe 41. Exhaust holes 44 are opened on both sides inside each mounting frame 12. There are several sets of exhaust holes 44. The exhaust holes 44 are located between the inner sides of the two sets of filters.
[0026] During operation, when slurry needs to be pressure filtered, the slurry to be treated is delivered to the outer side of the mounting frame 12 through the injection pipe. Simultaneously, the external hydraulic cylinder is activated, providing a corresponding horizontal pushing force to the push plate 14. This allows the push plate 14 to push the mounting frame 12 during horizontal movement, causing the mounting frames 12 to press against each other during synchronous rightward movement. This pressure on the flowing slurry causes solid impurities mixed in with the slurry to accumulate on the outside of the filter screen 13, i.e., on the outside of the mounting frame 12. After the slurry is pressure filtered, the electric slide rail 2 is driven by the external central control computer. The electric slide rail 2 can drive the moving frame 21 to move continuously to the right. During the rightward movement of the moving frame 21, the limiting baffle 24 on one side of the top of the moving frame 21 will be pressed by the pushing block 33 connected to the outside of the mounting frame 12, causing it to rotate downward. At the same time, it will drive the transmission rod 26 to rotate inside the hollow frame 25, which can cause the return torsion spring 27 to twist. This allows the return torsion spring 27 to deform during rotation and have a restoring torsional force. As the moving frame 21 continues to move to the right, the pushing block 33 can move out from the top of the limiting baffle 24 and lose the pressing force on the limiting baffle 24, and the return torsion spring 27 will... Under the torsional recovery action, the limiting baffle 24 can be driven to rotate and recover its position, and then the moving frame 21 is driven to the left. Under the blocking action of the right limiting baffle 24, the moving frame 21 can drive the single set of mounting frames 12 and filter screen 13 to move to the left synchronously, so that the mounting frames 12 and filter screen 13 can be automatically separated. Then, under the pressing action of the pressing block 31 and the left side cleaning completion pushing block 33, the limiting baffle 24 on the top left side of the moving frame 21 can always be kept in a downward rotating state. After cleaning the single set of mounting frames 12 and its surface filter screen 13, the moving frame... After the moving frame 21 continues to move to the right, the mounting frame 12 and the pressing block 31 on its side can automatically move away from the top of the moving frame 21, so that the moving frame 21 can continuously drive the subsequent mounting frame 12, which facilitates the automatic pushing and separating of the mounting frames 12 that are attracted to each other. At the same time, the air pump connected to the external and connecting pipe 42 is started. During its operation, the gas is pressurized and delivered to the inside of the air blowing pipe 41. Under the connecting and conveying action of the corrugated hose 43, the gas can be discharged from the inside of the mounting frame 12, and then the air can be blown from the side of the filter screen 13 to blow away and separate the solid impurities adsorbed and accumulated on its surface.
