Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a high-pressure press filter press. Background Technology

[0002] The working principle of a high-pressure filter press is to separate solid particles from liquid in a mixture by applying pressure and using the filtration effect of filter cloth. It is particularly suitable for processing materials that are highly viscous, have fine particles, and are difficult to separate, such as sludge, mud, and oil sludge. It is widely used in many fields such as chemical, petroleum, pharmaceutical, light industry, food, mineral processing, water treatment, electroplating, and metallurgy.

[0003] A search revealed Chinese patent publication number CN218784624U, which discloses a high-pressure diaphragm filter press filtration device, including a mounting base plate. A pressing system control cabinet is mounted on the top of the mounting base plate. A hydraulic cylinder mounting box is located on one side of the pressing system control cabinet. A pressing hydraulic cylinder is installed inside the hydraulic cylinder mounting box. A hydraulic cylinder drive shaft is located on one side of the pressing hydraulic cylinder. A filter press pressing plate is located on one side of the hydraulic cylinder drive shaft. A filter press filter plate is located on one side of the filter press pressing plate.

[0004] The aforementioned patent has the following shortcomings: after filtration, manual walking back and forth is required to pull apart the overlapping filter plates one by one so that the pressed filter cake can be removed, which makes the operation steps cumbersome and labor-intensive.

[0005] Therefore, a high-pressure pressing filter press is proposed. Utility Model Content

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example 1:

[0034] like Figure 1-7 As shown, a high-pressure press filter press includes a support 4 and two vertical plates 1 and 2 that are bolted to the top of the support 4.

[0035] Two symmetrically arranged guide rails 3 are fixedly connected to the opposite side of the upright plate 1 and upright plate 2. The opposite side of the two guide rails 3 is slidably fitted with pressure plate 1 5, pressure plate 2 7 and multiple filter plates 6. Elastic membranes 16 are provided on the opposite side of the pressure plate 1 5 and pressure plate 2 7 and on both sides of the inner wall of the filter plates 6. A hopper is formed between two adjacent elastic membranes 16. Hanging rings 13 are fixedly connected to the outer wall of the pressure plate 1 5, pressure plate 2 7 and all the filter plates 6. Two adjacent hanging rings 13 are connected by connecting ropes 14.

[0036] The pressure plate 5 and filter plate 6, filter plate 6 and pressure plate 7, as well as two adjacent filter plates 6, are all connected by connecting ropes 14. After pressure plate 7 moves to contact the first filter plate 6, it continues to move, which can drive the filter plate 6 to move until the filter plate 6 contacts the next filter plate 6, which can also drive the next filter plate 6 to move. When pressure plate 5, pressure plate 7 and all filter plates 6 have been overlapped, the movement of pressure plate 7 is stopped. At this time, mud can be poured into the silo to complete the filter pressing process. Conversely, after the filter pressing is completed, pressure plate 7 moves in the opposite direction to pull all the filter plates 6 apart one by one, so that the filter cake in the silo can fall off automatically.

[0037] By setting up hanging rings 13 and connecting ropes 14, the pressure plate 1 5, filter plate 6 and pressure plate 2 7 are connected together, so that only the pressure plate 2 7 needs to be pulled to drive all the filter plates 6 to separate or merge step by step, thus eliminating the need to operate each filter plate 6 separately and simplifying the operation steps.

[0038] In this embodiment, the outer wall of the pressure plate 2 7 is fixed with a slider 8 by bolts. The slider 8 is slidably fitted to the outer wall of the guide rail 3, and the inner wall of the slider 8 is connected with a lead screw 9 by thread. The lead screw 9 is rotatably connected to the inner walls of the vertical plate 1 and the vertical plate 2.

[0039] The outer wall of the second vertical plate 2 is fixed with a motor 10 by bolts, and the output shaft of the motor 10 is fixedly connected to the lead screw 9 by a coupling.

[0040] The motor 10 drives the lead screw 9 to rotate, and the screw thread drives the slider 8 to move horizontally along the outer wall of the guide rail 3. The slider 8 drives the pressure plate 7 to move, and the pressure plate 7 drives all the filter plates 6 to separate or merge step by step.

[0041] In this embodiment, the inner wall of the pressure plate 5 is fixedly connected to and connected to the conveying pipe 15, and the inner walls of all the filter plates 6 are fixedly connected to the through pipe 18. The conveying pipe 15, the through pipe 18 and the hopper are interconnected. One end of the conveying pipe 15 passes through the vertical plate 1 and is fixedly connected to the feeding pump. The input end of the feeding pump is connected to the storage tank through a pipe.

[0042] The inner walls of the pressure plate 5, filter plate 6, and pressure plate 7 are all provided with multiple filter holes 19, and the inner walls of the pressure plate 5, filter plate 6, and pressure plate 7 are also provided with through grooves 20 that communicate with the filter holes 19. The outer walls of the pressure plate 5, filter plate 6, and pressure plate 7 are fixedly connected with drain pipes 12 that communicate with through grooves 20. The inner walls of the vertical plate 1 and vertical plate 2 are fixedly connected with water receiving grooves 11, and the water outlet of the drain pipe 12 is located above the water receiving grooves 11.

[0043] The storage tank and feeding pump are not shown in the figure. They can be arranged in appropriate positions according to actual needs. In this embodiment, the specific position of their setting is not limited. After all the filter plates 6 are overlapped, the feeding pump is started to draw mud from the storage tank and transport it to all the silos through the conveying pipe 15 until the silos are full of mud. Then the feeding pump continues to transport mud into the silos, so that the mud is squeezed and the water in the mud is squeezed out. It flows through the filter hole 19 into the channel 20 and is finally discharged through the drain pipe 12. The water tank 11 discharges all the water to the subsequent treatment stage.

[0044] In this embodiment, a filter cake conveying mechanism is provided inside the support 4. The filter cake conveying mechanism includes multiple rotating shafts 23 and transmission rollers 24. The transmission rollers 24 are rotatably connected to the inner wall of the support 4 through the rotating shafts 23, and all the transmission rollers 24 are connected to the same transmission belt 25 on their outer walls.

[0045] One of the rotating shafts 23 is fixedly connected to a motor 22 via a coupling, and the motor 22 is fixed to the outer wall of the bracket 4 by bolts.

[0046] The starter motor 22 drives one of the rotating shafts 23 and the transmission roller 24 to rotate. With the transmission cooperation of the other rotating shafts 23 and the transmission roller 24, the transmission belt 25 is driven to rotate, thereby transporting the produced filter cake to the subsequent processing stage.

[0047] Example 2:

[0048] A high-pressure press filter press is provided in this embodiment, which is based on embodiment 1 with the following improvements, such as... Figure 5 , 6 As shown:

[0049] The inner walls of the pressure plate 5, filter plate 6, and pressure plate 7 are all fixedly connected with partitions 17, and a cavity 21 is formed between the elastic membrane 16 and the partitions 17.

[0050] After the mud has undergone initial compression filtration, high-pressure gas can be supplied to all chambers 21 using equipment such as air pumps and pressure tanks, which increases the volume inside the chambers 21, causing the elastic membrane 16 to undergo elastic deformation and perform secondary compression filtration of the mud. After the secondary compression is completed, the pressure is released, allowing the elastic membrane 16 to return to its initial state for the next use.

[0051] By setting up cavity 21 and supplying high-pressure gas into cavity 21 to increase its internal volume, the elastic membrane 16 can undergo elastic deformation to achieve secondary extrusion of the mud, thereby further improving the water output rate of the device.

[0052] Working Principle: When using this device, firstly, motor 10 drives screw 9 to rotate, which in turn drives slider 8 to move horizontally along the outer wall of guide rail 3. Slider 8 drives pressure plate 7 to move, and pressure plate 7 causes all filter plates 6 to merge sequentially. Once all filter plates 6 overlap, the feeding pump is started to extract slurry from the storage tank and transport it through conveying pipe 15 to all silos until the silos are full. Then, the feeding pump continues to pump slurry into the silos, causing the slurry to be compressed. The water in the slurry is squeezed out and flows through filter holes 19 into the channel 20, finally being discharged through drain pipe 12. Water collection tank 11 discharges all the water to subsequent treatment stages. Then, air pumps, pressure tanks, and other equipment are used to pump water into all cavities. High-pressure gas is supplied into chamber 21, increasing its volume. This causes the elastic membrane 16 to deform elastically, performing secondary compression filtration of the slurry. After the secondary compression, the pressure is released, allowing the elastic membrane 16 to return to its initial state for future use. After filtration, motor 10 drives screw 9 to reverse, using pressure plate 7 to open all filter plates 6 in stages. This causes the filter cake to fall onto the transmission belt 25, which then transports the filter cake to subsequent processing stages. During the gradual opening of the filter plates 6, when the connecting rope 14 is fully taut, the load on motor 10 increases instantaneously, and its speed decreases, creating a speed difference. This speed difference generates a vibration that can dislodge the filter residue remaining on the surface of the elastic membrane 16.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
