A filter press for papermaking wastewater Technical Field

[0001] This utility model relates to the field of filter press equipment technology, and in particular to a filter press for papermaking wastewater. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. Plate and frame filter presses are commonly used in the paper industry.

[0003] However, in the existing technology, some filter presses used for papermaking wastewater treatment usually involve opening the filter plates after filtration to clean the remaining paper solids. But most of the time, the cleaning work is done on a single filter plate, so the work efficiency is low and needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the existing technology that some filter presses used for papermaking wastewater treatment typically involve opening the filter plates after filtration to clean the remaining paper solids. However, this cleaning is mostly done on individual filter plates, resulting in low work efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a filter press for papermaking wastewater, comprising: a support base and multiple filter plates; multiple sets of sliders fixedly disposed on the surfaces of the multiple filter plates at symmetrical locations; and further comprising:

[0006] A hydraulic cylinder is fixedly installed on the inner wall of the support base. The output end of the hydraulic cylinder is provided with a squeezing plate. The squeezing plate is movably connected to the surface of one of the filter plates. Multiple sliders are slidably sleeved on the inner wall of the support base. The multiple sliders are connected to each other by steel cables.

[0007] Hydraulic cylinder two is fixedly installed on the inner wall of the support base. The output end of hydraulic cylinder two is provided with a movable frame. Hydraulic cylinder three is fixedly installed on the surface of the movable frame at a symmetrical position. The output ends of the two hydraulic cylinder three are provided with protrusions. One side surface of the two protrusions is movably connected to the surface of the slider.

[0008] An electric push rod is disposed on the surface of the support base. The output end of the electric push rod is provided with a limit frame, and multiple slide rods are slidably embedded inside the limit frame.

[0009] Preferably, bolts are threaded on the surfaces of the plurality of sliding rods at symmetrical locations, and one end of the plurality of bolts is movably connected to the surface of the limiting frame.

[0010] The technical effect of adopting the above-mentioned further solution is that when the bolt inside the slide rod is rotated, the slide rod is locked by one end of the bolt against the surface of the limit frame.

[0011] Preferably, the inner walls of the plurality of sliding rods are provided with slots, and spray plates are movably embedded inside the plurality of slots.

[0012] The technical advantage of adopting the above-mentioned further solution is that the spring can be installed through the slot opened inside the slide bar.

[0013] Preferably, positioning grooves are formed on the surfaces of the plurality of spray plates at symmetrical locations, and a transmission hose is connected to one side surface of the plurality of positioning grooves.

[0014] The technical advantages of adopting the above-mentioned further solution are: the positioning groove opened on the surface of the spray plate facilitates the positioning work, and the transmission hose on the surface facilitates the transmission of water flow.

[0015] Preferably, brushes are provided on the surfaces of the plurality of positioning grooves at symmetrical locations, and springs are fixedly provided on the surfaces of the slide rods at symmetrical locations.

[0016] The technical effect of adopting the above-mentioned further solution is that: the positioning groove is equipped with a brush, and when the positioning groove moves, the brush comes into contact with the surface of the filter plate to clean the stubborn impurities remaining on the surface.

[0017] Preferably, one end of each of the multiple springs is fixedly provided with a positioning pin, and one end of each positioning pin is movably embedded inside the positioning groove.

[0018] The technical effect of adopting the above-mentioned further solution is that when the positioning pin on the surface of the spring is pulled, the positioning pin can move inside the positioning groove, which facilitates positioning and release of the limit.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, wastewater from papermaking is transported to the interior of the filter plates via a pump and pipeline. Hydraulic cylinder one is activated, causing the extrusion plate to contact the adjacent filter plates and press them together, separating the wastewater inside the filter plates. After the operation is completed, hydraulic cylinder one resets, and hydraulic cylinder two is activated, moving the moving frame to the bottom of the filter plates. Hydraulic cylinder three then works, causing the protrusions to contact the sliders on the filter plate surface, causing hydraulic cylinder two to reset. Multiple steel cables connect two adjacent sliders, causing multiple filter plates to unfold, facilitating the cleaning of internal residues.

[0021] 2. In this utility model, based on the length of the steel cable, the rotating bolt positions the sliding rod between two adjacent filter plates. The electric push rod is then activated, causing the limiting frame to move the sliding rod downwards. This moves the spray plate inside the slot between the two adjacent filter plates. The pump body, through the transmission hose, transmits liquid to clean the filter plate surface. Simultaneously, a brush contacts the filter plate surface. During the downward movement and resetting process of the electric push rod, stubborn residues are cleaned. Furthermore, when a spray plate is damaged, the spring is pulled to disengage the positioning pin from the positioning groove, allowing the spray plate to be replaced, thus improving the functionality of the device.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, as shown in Figures 1-4, provides a filter press for papermaking wastewater, comprising: a support base 1 and multiple filter plates 101; multiple sets of sliders 1011 fixedly disposed on the surfaces of the multiple filter plates 101 at symmetrical locations; it also includes: a hydraulic cylinder 102 fixedly disposed on the inner wall of the support base 1, the output end of the hydraulic cylinder 102 being provided with a pressing plate 1021, the pressing plate 1021 being movably connected to the surface of one of the filter plates 101, and the multiple sliders 1011 being slidably sleeved on the inner wall of the support base 1, the multiple sliders 1011 being connected by steel cables 1012. Connected; hydraulic cylinder 2 103, fixedly mounted on the inner wall of support base 1, with a movable frame 1031 at the output end of hydraulic cylinder 2 103, and hydraulic cylinder 3 1032 fixedly mounted on the surface of the movable frame 1031 at a symmetrical position, with protrusions 1033 at the output ends of the two hydraulic cylinders 3 1032, and one side surface of the two protrusions 1033 movably connected to the surface of the slider 1011 therein; electric push rod 104, mounted on the surface of support base 1, with a limit frame 1041 at the output end of electric push rod 104, and multiple slide rods 1042 slidably embedded inside the limit frame 1041.

[0031] In this embodiment, wastewater from papermaking is transported to the interior of filter plate 101 via a pump and pipeline. Hydraulic cylinder 102 is activated, causing the extrusion plate 1021 to contact the adjacent filter plate 101 for pressing, thus separating the wastewater inside the filter plate 101. After the operation is completed, hydraulic cylinder 102 resets, and hydraulic cylinder 103 is activated, moving the moving frame 1031 to below the filter plate 101. In conjunction with hydraulic cylinder 1032, the protrusion 1033 contacts the slider 1011 on the surface of the filter plate 101, causing hydraulic cylinder 103 to reset. Multiple steel cables 1012 connect two adjacent sliders 1011, causing multiple filter plates 101 to unfold, facilitating the cleaning of internal residues.

[0032] In Example 2, bolts 1043 are threaded onto the surfaces of multiple sliding rods 1042 at symmetrical locations. One end of each bolt 1043 is movably connected to the surface of a limiting frame 1041. The inner walls of the multiple sliding rods 1042 have slots 1044, and spray plates 105 are movably embedded inside the slots 1044. Positioning grooves 1051 are formed on the surfaces of the multiple spray plates 105 at symmetrical locations. A transmission hose 1052 is connected to one side of each positioning groove 1051. Brushes 1053 are provided on the surfaces of the multiple positioning grooves 1051 at symmetrical locations. Springs 1045 are fixedly installed on the surfaces of the sliding rods 1042 at symmetrical locations. Positioning pins 1046 are fixedly installed on one end of each spring 1045, and one end of each positioning pin 1046 is movably embedded inside the positioning grooves 1051.

[0033] In this embodiment, based on the length of the steel cable 1012, the rotating bolt 1043 is used to position the slide rod 1042 between two adjacent filter plates 101. The electric push rod 104 is activated, causing the limiting frame 1041 to move the slide rod 1042 downwards, so that the spray plate 105 inside the slot 1044 moves down between the two adjacent filter plates 101. In conjunction with the pump body, liquid is transmitted through the transmission hose 1052 to clean the surface of the filter plate 101. At the same time, the brush 1053 contacts the surface of the filter plate 101. During the process of the electric push rod 104 moving down and resetting, stubborn residues are cleaned. At the same time, when the spray plate 105 is damaged, the spring 1045 is pulled to disengage the positioning pin 1046 from the inside of the positioning slot 1051, allowing the spray plate 105 to be replaced, thus improving the functionality of the device.

[0034] Working Principle: During operation, wastewater from papermaking is transported to the interior of filter plate 101 via a pump and pipeline. Hydraulic cylinder 102 is activated, causing the pressing plate 1021 to contact the adjacent filter plate 101 for pressing, separating the wastewater inside the filter plate 101. After operation, hydraulic cylinder 102 resets, and hydraulic cylinder 103 is activated, moving the moving frame 1031 to below the filter plate 101. Hydraulic cylinder 1032 then works, causing the protrusion 1033 to contact the slider 1011 on the surface of the filter plate 101, causing hydraulic cylinder 103 to reset. Multiple steel cables 1012 connect two adjacent sliders 1011, causing multiple filter plates 101 to unfold, facilitating the cleaning of internal residue. Additionally, according to the steel cables 1012... With a length of 012, rotating bolt 1043 positions slide rod 1042 between two adjacent filter plates 101. Activating electric push rod 104 causes limit bracket 1041 to move slide rod 1042 downwards, allowing spray plate 105 inside slot 1044 to move between two adjacent filter plates 101. This, combined with pump body and transmission hose 1052, cleans the surface of filter plate 101. Simultaneously, brush 1053 contacts the surface of filter plate 101. During the downward movement and resetting process of electric push rod 104, stubborn residue is cleaned. Furthermore, if spray plate 105 is damaged, pulling spring 1045 disengages positioning pin 1046 from the positioning slot 1051, allowing replacement of spray plate 105 and improving device functionality.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
