Chemical plate and frame filter press

Abstract

This utility model discloses a chemical plate and frame filter press, including a filter press body with two parallel slide rails mounted on it. Multiple filter plates are disposed between the two slide rails, and sliders are mounted on both sides of each filter plate. The sliders on both sides of the filter plate slide on the two slide rails respectively. The filter press also includes a demolding mechanism, which includes two oppositely arranged mounting seats. During demolding, a first driving device drives a buffer seat to rise, lifting the sliders and thus lifting the filter plates. After the filter plates are raised to a certain height, a second driving device drives a lifting block to rise or fall, lifting or placing the sliders on the buffer seat. This causes the filter plates to vibrate, removing the filter cake from the filter plates. Simultaneously, the buffer seat has a buffering and shock-absorbing function, preventing the various bolted connections on the filter press body from loosening due to vibration, thus reducing the maintenance burden on workers.

Description

[0001] This utility model relates to the field of filter press technology, and in particular to a chemical plate and frame filter press. Background Technology

[0002] Plate and frame filter presses are traditional solid-liquid separation equipment widely used in chemical, food, pharmaceutical, and environmental protection (such as sludge dewatering) industries. Their working principle involves pressure-driven solid particles in a suspension being trapped on a filter cloth to form a filter cake, while the liquid (filtrate) passes through the filter cloth and is discharged. Most existing plate and frame filter presses are equipped with a vibrating mechanism to improve the filter cake removal rate; however, the various bolted connections on the filter press body can loosen rapidly due to vibration, increasing the maintenance burden on operators. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a chemical plate and frame filter press. This solves the problem that existing plate and frame filter presses are mostly equipped with filter plate vibration mechanisms to improve the filter cake demolding rate, but various bolted connecting parts on the filter press body will loosen rapidly due to vibration, increasing the maintenance burden on the staff.

[0004] To achieve the above technical objectives, the present invention provides a chemical plate and frame filter press, comprising a filter press body, two parallel slide rails mounted on the filter press body, multiple filter plates disposed between the two slide rails, sliders mounted on both sides of the filter plates, the sliders on both sides of the filter plates slidingly disposed on the two slide rails respectively, the filter press further comprising a demolding mechanism, the demolding mechanism comprising two mounting seats disposed opposite to each other, the mounting seats being connected to a drive mechanism for driving them to move along the sliding direction of the sliders, the mounting seats having locking claws at both ends of the top of the mounting seats, a buffer seat being disposed between the two locking claws, the buffer seat being connected to a first drive device for driving its lifting and lowering, and a lifting block being disposed between the two locking claws, the lifting block being connected to a second drive device for driving its lifting and lowering.

[0005] Furthermore, the slide rail has a long strip structure, and the bottom of the slider is provided with a groove, through which the slider slides on the slide rail.

[0006] Furthermore, the drive mechanism adopts either a lead screw drive mechanism or a conveyor belt drive mechanism.

[0007] Furthermore, the engaging claw includes a hinge block mounted on the top of the mounting base, on which an engaging rod is hinged, and the engaging rod is connected to the mounting base by a first spring.

[0008] Furthermore, the buffer seat includes a lower seat plate connected to the first drive device and an upper seat plate disposed above the lower seat plate, with the top of the lower seat plate and the bottom of the upper seat plate connected by a second spring.

[0009] Furthermore, a limiting groove is provided at the top of the upper seat plate.

[0010] Furthermore, the first drive device is one of a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0011] The second drive device is one of a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0012] Furthermore, the beneficial effects of this utility model include: This utility model provides a chemical plate and frame filter press. When demolding is performed, the first driving device can drive the buffer seat to rise, thereby lifting the slider and the filter plate. After the filter plate is raised to a certain height, the second driving device can drive the lifting block to rise and fall, thereby lifting the slider or placing it on the buffer seat, which can cause the filter plate to vibrate and remove the filter cake on the filter plate. At the same time, the buffer seat has a buffering and shock absorption function, which can prevent the various bolt connection parts on the filter press body from loosening due to vibration, and reduce the maintenance burden of the plate and frame filter press for the workers.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] This utility model embodiment provides a chemical plate and frame filter press, such as Figure 1-2As shown, the filter press includes a filter press body 1, on which two slide rails 11 are mounted in parallel. Multiple filter plates 2 are disposed between the two slide rails 11. Slider blocks 21 are mounted on both sides of each filter plate 2, and the sliders 21 on both sides of the filter plate 2 slide on the two slide rails 11 respectively. The filter press also includes a demolding mechanism 3, which includes two mounting seats 31 arranged opposite each other. The mounting seats 31 are connected to a drive mechanism 32 for driving them to move along the sliding direction of the sliders 21. The drive mechanism 32 is either a screw drive mechanism or a conveyor belt drive mechanism. Each mounting seat 31 has a locking claw 33 at both ends of its top. A buffer seat 34 is disposed between the two locking claws 33. The buffer seat 34 is connected to a first drive device 35 for driving its lifting and lowering. The first drive device 35 is either a cylinder, a hydraulic cylinder, or an electric telescopic rod. A lifting block 36 is also provided between the two locking claws 33. The lifting block 36 is connected to a second drive device 37 for driving its lifting and lowering. The second drive device 37 is one of a cylinder, a hydraulic cylinder or an electric telescopic rod. When demolding is performed, the first drive device 35 can drive the buffer seat 31 to rise, so as to lift the slider 21 and thus lift the filter plate 2. When the filter plate 2 is raised to a certain height, the second drive device 37 can drive the lifting block 36 to rise and fall, so as to lift the slider 21 or place it on the buffer seat 34, so that the filter plate 2 can vibrate and remove the filter cake on the filter plate 2. At the same time, the buffer seat 31 has a buffering and shock absorption function, which can prevent the various bolt connection parts on the filter press body 1 from loosening due to vibration, and reduce the burden of maintenance of the plate and frame filter press by the staff.

[0018] It should be noted that the slide rail 11 is a long strip-shaped mechanism, and the bottom of the slider 21 is provided with a sliding groove for sliding on the slide rail 11, so that the slider 21 can slide or rise and fall on the slide rail 11, thereby allowing the filter plate 2 to slide or rise and fall horizontally.

[0019] In this embodiment, the locking claw 33 includes a hinge block 331 mounted on the top of the mounting base 31. A locking rod 332 is hinged on the hinge block 331. The locking rod 332 is connected to the mounting base 31 by a first spring 333. At the same time, the locking rod 332 has an arc-shaped structure, which can effectively lock the slider 21 during the movement of the mounting base 31.

[0020] In this embodiment, the buffer seat 34 includes a lower seat plate 351 connected to the first driving device 35 and an upper seat plate 352 disposed above the lower seat plate 351. The top of the lower seat plate 351 and the bottom of the upper seat plate 352 are connected by a second spring 353. The structure is simple and the buffering effect is good. At the same time, the top of the upper seat plate 352 is provided with a limiting groove 3521. The limiting groove 3521 can restrict the slider 21, so that when the lifting block 36 lowers the slider 21, the slider 21 can fall stably onto the buffer seat 34.

[0021] Specifically, when demolding is performed, the drive mechanism 32 drives the mounting base 31 to move, engaging the slider 21 between the two engaging claws 33 and dragging the slider 21 to separate the filter press plate 2 from the adjacent filter press plate 2. After the two filter press plates 2 are separated, the first drive device 35 drives the buffer seat 31 to rise, lifting the slider 21 and thus lifting the filter press plate 2. When the filter press plate 2 is raised to a certain height, the second drive device 37 drives the lifting block 36 to rise and fall, lifting or placing the slider 21 on the buffer seat 34, thereby causing the filter press plate 2 to vibrate and remove the filter cake on the filter press plate 2. At the same time, the buffer seat 31 has a buffering and shock absorption function, which can prevent the various bolted connection parts on the filter press body 1 from loosening due to vibration, reducing the maintenance burden of the plate and frame filter press for the staff.

[0022] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
