Technical Field
[0001] This utility model relates to the technical field of calcium salt production equipment, and in particular to a pressure filter device for calcium salt production. Background Technology
[0002] Most existing filter presses are horizontal in structure, using lateral pressure to drive all the filter plates to stack horizontally. After the liquid is squeezed out, the filter cake is scraped off by directional movement and manual assistance. However, horizontal filter presses are large in size and have a large footprint, requiring more space in the factory or workshop.
[0003] A search revealed that existing technology CN218357685U describes a filter press device for calcium salt production, comprising a body and a drive cylinder. The body has a feed inlet and includes a vertical filter cylinder. A height adjuster is located at the top of the filter cylinder, and the drive cylinder is mounted on the height adjuster. The filter cylinder has a main chamber and three vertical chambers inside. The main chamber contains a main piston body connected to the drive cylinder and three auxiliary piston bodies connected to the main piston body. Several water filtration holes are located near the bottom of the filter cylinder. A water tank is arranged around the filter cylinder outside the water filtration holes, and a drain pipe is installed on the water tank. A slag box is connected to the bottom of the filter cylinder. A lifting cylinder is located at the center of the bottom of the slag box, and a top plate is located at the movable end of the lifting cylinder. A slag outlet is located at the top of the slag box, which is movably sealed to the top plate. This device has a reasonable design, simple structure, high space utilization, and helps reduce space and labor costs, making it suitable for large-scale promotion.
[0004] However, when the applicant used the above device, he found that: there are several water filter holes on the filter cylinder near its bottom, and water tanks are arranged around the filter cylinder outside the water filter holes. However, in actual filter pressing, material residue easily enters the water filter holes and causes blockage. Moreover, the water filter holes are located inside the water tank and are an integral structure with the filter cylinder, making subsequent cleaning very cumbersome and inconvenient to use. Utility Model Content
[0005] The purpose of this invention is to provide a pressure filter device for calcium salt production, which aims to solve the problem of inconvenient cleaning of the existing pressure filter device's filtration structure.
[0006] To achieve the above objectives, this utility model provides a filter press device for calcium salt production, including a frame, a receiving box placed at the bottom of the frame, a filter press cylinder welded to the top, and auxiliary components.
[0007] The auxiliary components include a support base, a filter disc, a first driving component, a pull rod, a support column, a drain pipe, a guide frame, a sliding frame, a piston, a feeding component, and a downward component. The support base is slidably connected to the filter cylinder and is located at the bottom of the filter cylinder. The filter disc is fixed to the top of the support base by two pull rods and has multiple filter holes at the bottom. The pull rods are threaded to the filter disc and have a T-shaped structure. The first driving component is installed below the rear side of the filter cylinder, and its output end is connected to the connecting ear on the rear side of the support base. The support column is integrally set at the bottom of the filter disc and abuts against the bottom of the inner cavity of the support base. The drain pipe is welded to the outlet of the support base and connected to a flexible hose at the bottom, which extends into the receiving box. The guide frame is welded to the left and right sides of the support base. The sliding frame is detachably connected to the frame and slidably connected to the guide frame. The piston is slidably connected to the filter cylinder. The feeding component is located on one side of the filter cylinder. The downward component is located at the top of the filter cylinder and is connected to the connecting rod of the piston.
[0008] The feeding component includes a fixed plate and a feeding pipe. The feeding pipe is welded to the fixed plate and is slidably inserted into the feed inlet of the filter press cylinder, and its discharge outlet is located below the lowest point of the piston. The fixed plate is detached and installed on the frame.
[0009] The downward component includes a gantry frame and a power unit. The gantry frame is mounted on the cover plate at the top of the filter press cylinder. The power unit is located on the side of the gantry frame near the piston.
[0010] The power component includes a second drive member and a T-shaped screw. The second drive member is mounted on the gantry frame, and the T-shaped screw is detachably mounted on its output end. The T-shaped screw is connected to the threaded cavity on the connecting rod of the piston.
[0011] The calcium salt production filter press further includes a matching component, which includes a bent pipe and a conical hopper. The bent pipe is welded to the feed inlet side of the feed pipe. The conical hopper is detachably connected to the bent pipe and is located on the feed inlet side of the bent pipe.
[0012] This utility model discloses a filter press device for calcium salt production. When the filter mechanism of the device needs to be cleaned, the first driving component is controlled to move. After the first driving component moves, it pushes the support base to slide downward and finally slides out of the filter press cylinder. Then, the filter residue on the filter plate can be cleaned directly. At the same time, if the filter plate's water filtration holes are blocked and need to be removed for cleaning, the two pull rods can be removed directly, and the filter plate can be slid upward and removed for cleaning. In this application, when cleaning the filter plate, it can be quickly moved to the outside of the device by the first driving component and removed directly after removing the pull rods, achieving convenient disassembly and cleaning. This solves the problem of inconvenient cleaning of the existing filter press device's filter structure. Attached Figure Description

[0022] In this embodiment, a receiving box 102 is placed at the bottom of the frame 101, and a filter press cylinder 103 is welded to the top. A drain valve is provided on the rear side of the receiving box 102, and a detachable cover plate is provided on the top of the filter press cylinder 103. Meanwhile, all components in this application are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle areas of this device, all the aforementioned electrical components, referring to power elements, electrical components, and compatible distribution cabinets and power supplies, are connected by wires. The specific connection methods should refer to the working principle described below, where the electrical connections between each electrical component are completed in sequence. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, without describing the electrical control.
[0023] The support base 104 is slidably connected to the filter press cylinder 103 and located at the bottom of the filter press cylinder 103. The filter disc 105 is fixed to the top of the support base 104 by two pull rods 107. Multiple filter holes 118 are provided at the bottom. The pull rods 107 are threadedly connected to the filter disc 105 and have a T-shaped structure. The first drive member 106 is installed below the rear side of the filter press cylinder 103, and its output end is connected to the rear connecting lug of the support base 104. The support column 108 is integrally disposed at the bottom of the filter disc 105 and abuts against the support base. At the bottom of the inner cavity of 104, the drain pipe 109 is welded to the outlet of the support base 104, and a movable hose is connected to the bottom. The movable hose extends into the receiving box 102. The guide frame 110 is welded to the left and right sides of the support base 104. The sliding frame 111 is detachably connected to the frame 101 and slidably connected to the guide frame 110. The piston 112 is slidably connected to the filter cylinder 103. The feeding component is located on one side of the filter cylinder 103. The descending component is located on the top of the filter cylinder 103 and is connected to the connecting rod of the piston 112. The support base 104 has a T-shaped structure. During installation, an O-ring seal is fitted onto the mating part with the filter cylinder 103. Eight support columns 108 are evenly spaced in a ring around the bottom outer side of the filter disc 105 to form a support structure after installation. Multiple water-filtering holes 118 are provided at the bottom of the filter disc 105. The bottom of each water-filtering hole 118 forms a water storage cavity with the bottom of the support base 104. The drain pipe 109 is welded and fixed, and communicates with the water storage cavity. Two threaded holes are symmetrically provided at the bottom of the filter disc 105 to facilitate the installation of the T-shaped pull rod 107. The support base 104 has through holes for installing the pull rod 107. The first driving component 106 is a cylinder or hydraulic cylinder, fixed to a fixed part on the lower rear side of the filter cylinder 103. Its output end is connected to the connecting lug on the bottom rear side of the support base 104 by bolts. The guide frame 110 is symmetrically welded to the support base 104, and its round rod is slidably engaged with the detachable T-shaped sliding sleeve on the sliding frame 111. The sliding frame 111 is fixed to the frame 101 by bolts. The piston 112 has a T-shaped structure and a connecting rod with a threaded cavity at the top. The feeding component is used for adding materials. The downward component is used to drive the piston 112 downward to achieve material pressure filtration.
[0024] Secondly, the feeding pipe 114 is welded to the fixed plate 113 and slidably inserted into the feed inlet of the filter press cylinder 103, and its discharge port is located below the lowest point of the piston 112; the fixed plate 113 is detached and installed on the frame 101. The fixed plate 113 is fixed by bolts, and the feeding pipe 114 is installed at a certain tilt angle.
[0025] Then, the gantry frame 115 is installed on the cover plate at the top of the filter press cylinder 103; the power unit is located on the side of the gantry frame 115 near the piston 112. The gantry frame 115 is fixed by positioning pins and bolts, and the power unit is used to drive the piston 112 to move vertically reciprocating.
[0026] Finally, the second drive component 116 is mounted on the gantry frame 115, and the T-shaped screw 117 is detachably mounted on its output end; the T-shaped screw 117 is connected to the threaded cavity on the connecting rod of the piston 112. The second drive component 116 is a cylinder or hydraulic cylinder, fixed by bolts. A disc is mounted on the output end of the second drive component 116 by multiple countersunk bolts. The disc is connected to the disc of the T-shaped screw 117 by bolts. The external thread end of the T-shaped screw 117 is connected to the threaded cavity on the connecting rod of the piston 112, and an anti-loosening nut is provided for engagement.
[0027] When using this invention to solve the problem of inconvenient cleaning of existing filter press structures, the device is powered on, and then the material is fed into the feeding pipe 114, falling into the filter disc 105. Then, the second driving component 116 is controlled to move the piston 112 downwards to cooperate with the filter disc 105 for filtration. The residue is stored above the filter disc 105, and the liquid falls from the water filtration hole 118 into the internal cavity of the support base 104, finally being discharged through the drain pipe 109. When cleaning the filter mechanism is required, the first driving component 106 is first controlled to move. After the first driving component 106 moves, it pushes the support base 104 downwards, finally allowing it to completely slide out of the filter press cylinder 103. After sliding out, the filter disc 105 and the bottom of the filter press cylinder 103 have a suitable operating distance, and then the filter residue on the filter disc 105 can be cleaned directly. If the filter holes 118 of the filter disc 105 become clogged and need to be removed for cleaning, simply remove the two pull rods 107, then slide the filter disc 105 upwards and remove it for cleaning. During installation, the filter disc 105 has a detachable positioning pin at the bottom of its stepped top portion and a positioning hole on the support base 104. When the positioning pin and positioning hole are engaged, the through hole on the support base 104 aligns with the threaded hole at the bottom of the filter disc 105 during installation. In this application, when cleaning the filter disc 105, it can be quickly moved outside the device using the first driving component 106 and removed after the pull rods 107 are removed, achieving convenient disassembly and cleaning. When cleaning the filter disc 105, the liquid in the receiving box 102 must be completely drained, thus solving the problem of inconvenient cleaning of existing filter press structures.
[0028] Example 2:
[0029] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of a filter press device for calcium salt production. Based on the first embodiment, this utility model provides a filter press device for calcium salt production. The filter press device for calcium salt production also includes a matching component, which includes a bent pipe 201 and a conical hopper 202.
[0030] The bent pipe 201 is welded to the inlet side of the feeding pipe 114; the conical hopper 202 is detachably connected to the bent pipe 201 and is located on the inlet side of the bent pipe 201. The outlet end of the bent pipe 201 is welded to the inlet of the feeding pipe 114, and a mounting flange is provided on the inlet side. The mounting flange of the conical hopper 202 is connected to the mounting flange on the bent pipe 201 by a screw and nut.
[0031] In this embodiment, by setting the bend 201 and the conical hopper 202, the conical hopper 202 structure is more conducive to rapid feeding than feeding directly through the inclined feeding pipe 114.
