Description

Technical Field

[0001] This application relates to the field of chamber filter press technology, and in particular to an automated water-washing chamber filter press. Background Technology

[0002] In the fields of chemical industry, pharmaceutical industry, food processing, and environmental protection, chamber filter presses are an important solid-liquid separation device. They apply pressure to multiple filter plates through a pressing plate, causing the slurry to be squeezed between the filter plates, thereby achieving solid-liquid separation. The solid filter residue is trapped on the filter cloth, while the liquid passes through the filter cloth and is discharged, achieving the purpose of separation and purification.

[0003] However, some existing chamber filter presses, such as the FBXY-X80 / 1000-U chamber filter press, do not have automatic cleaning functions. After the filter press completes a solid-liquid separation operation, a large amount of filter residue will remain on the filter plates. If this filter residue is not removed in time, it will affect the efficiency and effect of the next filter press operation, resulting in a slower filtration speed. Currently, the common way to deal with these filter presses that do not have automatic cleaning functions is to manually remove the plates for cleaning.

[0004] In practice, operators first need to manually loosen the pressure plates, then remove each filter plate from the crossbeam one by one, and move the filter plates to a dedicated cleaning area. High-pressure water guns or other cleaning tools are then used to rinse the filter plates and remove the filter residue. After cleaning, the filter plates are reinstalled and re-pressed. This process is labor-intensive and inefficient.

[0005] To address the aforementioned issues, an automated water-washing chamber filter press is now designed. Utility Model Content

[0006] This application provides an automated water-washing chamber filter press to solve the problem that some models of existing chamber filter presses do not have automatic cleaning functions, and manual cleaning of the plates is required after the filter press completes a solid-liquid separation operation.

[0012] In some embodiments, the flushing pipe includes a water storage plate with a cavity for storing cleaning fluid inside. Two infusion pipes are arranged opposite each other below the water storage plate in a U-shape, and a plurality of nozzles are arranged on opposite sides of the two infusion pipes.

[0013] In some embodiments, the lifting unit includes two guide rods that are inserted into a fixed base, an electric push rod II disposed on the fixed base, the piston rod of the electric push rod II being connected to the water storage plate, and the bottom end of the guide rod being connected to the water storage plate.

[0014] In some embodiments, a liquid supply mechanism is also included for injecting liquid into the water storage plate; The liquid supply mechanism includes a liquid supply tank and a pump body. The outlet end of the pump body is connected to a hose, the other end of which is connected to the water storage plate. The inlet end of the pump body is connected to the liquid supply tank.

Through the combined use of the pusher plate mechanism and the cleaning mechanism, the filter press plates can be cleaned automatically without the need for manual removal and cleaning, which greatly saves cleaning time and labor costs and improves overall production efficiency.

[0016] The coordinated movement of the traveling and lifting units allows the nozzles to move flexibly in both horizontal and vertical directions, achieving comprehensive and uniform rinsing of the filter plates, ensuring a more thorough cleaning and further improving cleaning efficiency.

[0017] The push plate mechanism can separate adjacent filter plates, allowing the nozzle to contact the surface of the filter plates more directly, effectively removing filter residue from the filter plates and avoiding incomplete cleaning caused by the close contact of the filter plates, thus ensuring the cleaning quality.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application provides an automated water-washing chamber filter press, which solves the problem in the related art that some models of existing chamber filter presses do not have automatic cleaning functions, and that manual cleaning of the plates is required after the filter press completes a solid-liquid separation operation.

[0023] Please see Figures 1-3 An automated water-washing chamber filter press includes: a body 1 with two crossbeams 2 arranged opposite each other on it; a head plate 3, multiple filter plates 4, and a pressing plate 5 arranged sequentially along the length of the body 1 on the two crossbeams 2; handles 41 are provided on both sides of the filter plates 4; a hydraulic mechanism 6 is provided at one end of the body 1, which is used to push the pressing plate 5 to squeeze the multiple filter plates 4; and a slurry supply valve 7 is provided at the other end of the body 1, which is used to supply slurry to the filter plates 4. The crossbeam 2 is provided with a push plate mechanism 8 for separating the filter press plate 4. It includes a driving member 81 provided at the bottom of the crossbeam 2 and a pushing member 82 arranged in the crossbeam 2. The pushing member 82 pushes the handle 41 on the filter press plate 4. The driving member 81 is connected to the pushing member 82 and is used to drive the pushing member 82 to move along the length of the crossbeam 2 and push the filter press plate 4. The machine body 1 is provided with a cleaning mechanism 9 for rinsing the filter press plate 4. It includes a mounting frame 91 on the machine body 1, a traveling unit 92 on the mounting frame 91, a lifting unit 93 connected to the traveling unit 92, and a rinsing pipe 94 arranged below the lifting unit 93. Multiple nozzles 95 for rinsing the filter press plate 4 are arranged opposite each other on the rinsing pipe 94.

[0024] In the initial state, the piston rod of the oil cylinder 61 of the hydraulic mechanism 6 is in the retracted state, and the pressing plate 5 is in contact with the multiple filter plates 4.

[0025] When the slurry supply valve 7 is opened, the slurry is supplied between two adjacent filter plates 4. As the slurry is continuously injected, the liquid flows out through the filter cloth under pressure, while the solid filter cake is trapped on the surface of the filter cloth and gradually forms a filter cake between the filter plates 4. When the set filtration time or pressure is reached, the hydraulic power station 62 of the oil pressure mechanism 6 is started to squeeze the multiple filter plates 4, further squeezing out the residual liquid in the filter cake and improving the solid-liquid separation effect.

[0026] After the filter press operation is completed, the piston rod of the oil cylinder 61 of the hydraulic mechanism 6 retracts, the push plate mechanism 8 starts to work, the pusher 82 starts and contacts the handle 41 of the outermost filter press plate 4. Then, the drive 81 starts and drives the pusher 82 to move, thereby pushing the corresponding filter press plate 4, so that the adjacent filter press plates 4 are separated to create a sufficient gap. The above steps are repeated to achieve the separation of multiple filter press plates 4.

[0027] During the separation process of the filter press plates 4, the cleaning mechanism 9 starts to operate and the traveling unit 92 is activated, causing the entire cleaning mechanism 9 to move along the length of the machine body 1, covering the positions of all filter press plates 4.

[0028] When the cleaning mechanism 9 moves to the appropriate position, the lifting unit 93 is activated, its piston rod extends, and drives the flushing pipe 94 to gradually descend, extending to the gap between two adjacent filter plates 4. At the same time, the cleaning liquid enters the flushing pipe 94, and the nozzle 95 sprays the cleaning liquid onto the surface of the filter plate 4 to flush the filter residue on the filter plate.

[0029] The traveling unit 92 and the lifting unit 93 work together to move the nozzle 95 in the horizontal and vertical directions, so as to thoroughly and evenly wash the multiple filter plates 4 and ensure that the filter residue is completely removed.

[0030] By using the push plate mechanism 8 and the cleaning mechanism 9 together, the cleaning of the filter press plate 4 can be completed automatically, eliminating the need for manual removal of the plates for cleaning, which greatly saves cleaning time and labor costs and improves overall production efficiency.

[0031] With the cooperation of the traveling unit 92 and the lifting unit 93, the nozzle 95 can move flexibly in the horizontal and vertical directions, so as to achieve a comprehensive and uniform rinsing of the filter plate 4, ensuring a more thorough cleaning and further improving the cleaning efficiency.

[0032] The push plate mechanism 8 can separate adjacent filter plates 4, allowing the nozzle 95 to contact the surface of the filter plate 4 more directly, effectively removing filter residue from the filter plate, avoiding incomplete cleaning caused by the tight fit of the filter plates, and ensuring cleaning quality.

[0033] like Figure 1 and Figure 2 As shown, the hydraulic mechanism 6 includes a cylinder 61 mounted on the machine body 1 and a hydraulic power station 62 mounted on one side of the machine body 1. The piston rod of the cylinder 61 contacts the pressure plate 5, and the hydraulic power station 62 and the cylinder 61 are connected by an oil pipe.

[0034] In the initial state, the hydraulic power station 62 is not started, there is no hydraulic oil pressure in the cylinder 61, and the piston rod of the cylinder 61 is in the retracted state.

[0035] When the slurry supply valve 7 is opened, the slurry begins to be supplied between the filter plates 4. After the initial solid-liquid separation, the filter plates 4 need to be further pressed to improve the solid-liquid separation effect. At this time, the hydraulic power station 62 is started, and the hydraulic pump in the hydraulic power station 62 starts to work, drawing hydraulic oil from the oil tank. After pressure regulation, filtration and other treatments, high-pressure hydraulic oil is delivered to the oil cylinder 61 through the oil pipe.

[0036] As high-pressure hydraulic oil enters the cylinder 61, the pressure inside the cylinder 61 increases. Under the action of the hydraulic oil pressure, the piston rod of the cylinder 61 begins to extend, pushing the pressing plate 5, which is in contact with the piston rod, to move towards the head plate 3. During the movement, the pressing plate 5 gradually squeezes multiple filter plates 4, making adjacent filter plates 4 fit tightly together. The pressure between the filter plates increases, thereby further squeezing out the residual liquid in the filter cake and achieving efficient solid-liquid separation.

[0037] When the pressing plate 5 presses the filter plate 4 to the set pressure value, the pressure control system in the hydraulic power station 62 starts to work. By adjusting the output flow of the hydraulic pump, the pressure in the oil cylinder 61 is kept at the set pressure value to maintain pressure.

[0038] When the filter press operation is completed, the hydraulic power station 62 changes the flow direction of the hydraulic oil, causing the oil pressure in the rod chamber and rodless chamber of the cylinder 61 to change. The piston rod of the cylinder 61 begins to retract, driving the pressing plate 5 to move away from the head plate 3, thus releasing the filter press plate 4.

[0039] like Figure 3 and Figure 4As shown, in one embodiment, the driving component 81 includes a housing 811 disposed below the crossbeam 2, the crossbeam 2 having a through hole 21 inside, and the crossbeam 2 communicating with the housing 811; a driving motor 812 is disposed inside the housing 811, the output shaft of the driving motor 812 is provided with a lead screw 813, the other end of the lead screw 813 being rotatably connected to the inner wall of the housing 811, a transmission block 814 is disposed on the outer side of the lead screw 813, and a threaded hole adapted to the lead screw 813 is opened in the transmission block 814; the pushing component 82 is connected to the transmission block 814.

[0040] The output shaft of the drive motor 812 starts to rotate, driving the lead screw 813 connected to it to rotate synchronously. Since the other end of the lead screw 813 is rotatably connected to the inner wall of the housing 811, the lead screw 813 can rotate stably inside the housing 811.

[0041] When the lead screw 813 rotates, according to the principle of lead screw transmission, the rotation of the lead screw 813 causes the transmission block 814 to move along the axial direction of the lead screw under the action of the thread, and the transmission block 814 will move linearly in the length direction of the lead screw 813. The linear motion of the transmission block 814 is directly transmitted to the pusher 82, which pushes the handle 41 on the filter press plate 4. As the pusher 82 moves, a gap is created between adjacent filter press plates 4, thereby achieving the purpose of separating two adjacent filter press plates 4.

[0042] like Figure 3 and Figure 4 As shown, in one embodiment, the pusher 82 includes an electric push rod 821 disposed in the through hole 21, the bottom of the electric push rod 821 being connected to the transmission block 814; the piston rod of the electric push rod 821 is provided with a lever 822.

[0043] The drive unit 81 is activated, causing the electric push rod 821 to move synchronously within the through hole 21 of the crossbeam 2.

[0044] When the electric push rod 821 moves between the two filter plates 4, the electric push rod 821 is activated, its piston rod extends, and drives the lever 822 to extend upward from the through hole 21. The drive unit 81 is activated again, causing the electric push rod 821 and the lever 822 to move in opposite directions. During the movement, the lever 822 will contact the handle 41 on the filter plate 4 and apply a pushing force to the handle 41, pushing the filter plate 4 to separate it from the adjacent filter plate 4. The above steps are repeated to gradually separate multiple filter plates 4.

[0045] After the separation operation of the filter press plate 4 is completed, the piston rod of the electric push rod 821 retracts, driving the lever 822 back into the through hole 21.

[0046] like Figure 3 and Figure 5 As shown, in one embodiment, the traveling unit 92 includes a linear electric slide rail 921 arranged on a mounting frame 91, and slide rails 922 arranged opposite to each other on the mounting frame 91 and located on both sides of the linear electric slide rail 921. Slider blocks 923 are provided on the slide rails 922. Fixed seats 924 are provided at the bottom of the two sliders 923. The movable block at the bottom of the linear electric slide rail 921 is connected to the fixed seat 924. The fixed seat 924 is a rectangular frame plate.

[0047] After receiving instructions from the control system, the linear electric slide rail 921 starts operating its internal drive motor. The motor converts the rotational motion into linear motion via a synchronous belt, driving the moving block at the bottom of the linear electric slide rail 921 to perform linear reciprocating motion. The linear motion of the moving block is transmitted to the fixed base 924, causing the fixed base 924 to move along the length of the linear electric slide rail 921 along with the moving block.

[0048] During the movement of the fixed seat 924, the slide rail 922 serves as a guide and support. The slider 923 is mounted on the slide rail 922 and slides on the slide rail 922 as the fixed seat 924 moves. The cooperation between the slide rail 922 and the slider 923 ensures the smoothness and straightness of the movement of the fixed seat 924 and reduces the offset and shaking during the movement.

[0049] like Figure 5 and Figure 6 As shown in this embodiment, the flushing pipe 94 includes a water storage plate 941. The water storage plate 941 has a cavity for storing cleaning fluid. Two infusion pipes 942 are arranged opposite each other below the water storage plate 941. The two infusion pipes 942 are U-shaped. A plurality of nozzles 95 are arranged on the opposite side of the two infusion pipes 942.

[0050] The cavity inside the water storage plate 941 serves as a storage space for cleaning fluid, providing a reserve of cleaning fluid for subsequent rinsing operations.

[0051] When rinsing is required, the cleaning fluid flows from the cavity of the water storage plate 941 into the two oppositely arranged infusion pipes 942 below. Since the infusion pipes 942 are U-shaped, the cleaning fluid will flow inside the pipes and fill the entire infusion pipe 942. Multiple nozzles 95 spray the cleaning fluid in a mist to effectively rinse the filter press plate 4 area.

[0052] The U-shaped infusion tube 942 can increase the flow path of the cleaning fluid inside the tube, allowing the cleaning fluid to be better mixed and stabilized inside the tube, and ensuring that the pressure and flow rate of the sprayed cleaning fluid are more uniform.

[0053] Multiple nozzles 95 are arranged on opposite sides of the two infusion pipes 942, which enables the spray range of the nozzles 95 to cover the surface of the two filter plates 4, thereby improving cleaning efficiency.

[0054] like Figure 5 and Figure 6 As shown, in one embodiment, the lifting unit 93 includes two guide rods 931 that are inserted into a fixed base 924, and an electric push rod 932 disposed on the fixed base 924. The fixed base 924 has a through hole for the extension of the piston rod of the electric push rod 932 and a sliding hole for the extension of the guide rods 931. The piston rod of the electric push rod 932 is connected to the water storage plate 941, and the bottom end of the guide rod 931 is connected to the water storage plate 941.

[0055] When the electric push rod 932 receives the electrical signal from the control system, its piston rod extends and retracts. During the extension and retraction of the piston rod of the electric push rod 932, due to the guiding effect of the guide rod 931, the water storage plate 941 can only move in a straight line along the direction of the guide rod 931, thus avoiding the water storage plate 941 from shaking or deviating during the lifting and lowering process.

[0056] When the piston rod extends, it pushes the water storage plate 941 downward. When the piston rod retracts, it pulls the water storage plate 941 upward, thereby realizing the raising and lowering of the water storage plate 941 and the connected flushing pipe 94 and other components.

[0057] like Figure 7 As shown, it further includes a liquid supply mechanism 10, which is used to inject liquid into the water storage plate 941; the liquid supply mechanism 10 includes a liquid supply tank 101 and a pump body 102, the outlet end of the pump body 102 is connected to a hose 103, the other end of the hose 103 is connected to the water storage plate 941, the inlet end of the pump body 102 is connected to the liquid supply tank 101, and the liquid supply tank 101 is provided with a liquid injection port.

[0058] The liquid supply tank 101 serves as a storage container for the cleaning fluid. An appropriate amount of cleaning fluid is injected into the tank through the liquid injection port provided on it, in preparation for the liquid supply operation.

[0059] The pump body 102 starts working, drawing the cleaning fluid from the supply tank 101 into the pump body 102. Under the pressure of the pump body 102, the cleaning fluid drawn into the pump body is transported to the water storage plate 941 through the hose 103 connected to the outlet end of the pump body 102.

[0060] The water storage plate 941 has an internal cavity for storing the delivered cleaning fluid for use in flushing the pipe 94.

[0061] like Figure 7 As shown, the outlet end of the pump body 102 is provided with a filter tank, and the other end of the filter tank is connected to the hose 103.

[0062] When the pump body 102 is working, it draws out the cleaning fluid from the supply tank 101 and pressurizes it to the outlet end. When the cleaning fluid reaches the outlet end, it enters the filter tank. The filter tank is equipped with a filter medium filter element. When the cleaning fluid flows through the filter medium, the impurities in it are intercepted on the surface of the filter medium, while the clean cleaning fluid after filtration flows out through the other end of the filter tank.

[0063] To ensure that the filter tank can effectively intercept impurities and prevent cleaning fluid leakage, sealing rings or gaskets are provided at the connection between the filter tank and the outlet end of the pump body 102 and the hose 103 to achieve reliable sealing.
