Description

Technical Field

[0001] This utility model relates to the field of filter machines, and in particular to a diatomaceous earth filter machine. Background Technology

[0002] Currently, diatomaceous earth filters are widely used in solid-liquid separation processes for beverages such as alcoholic beverages. Because diatomaceous earth is in powder form, it needs to adhere to a carrier to achieve its filtering effect. Existing filter components used as diatomaceous earth carriers primarily consist of a stainless steel mesh wrapped with cotton bags, with filter discs horizontally stacked inside the filter.

[0003] A search revealed Chinese Patent Publication No. CN221513616U, which discloses a diatomaceous earth microporous filter, including a body and a cleaning brush. The cleaning brush is disposed within the inner cavity of the body, and a limiting mechanism is provided on the outside of the cleaning brush. The limiting mechanism includes a receiving groove, a limiting block, a rotating wheel, and a telescopic component. This utility model utilizes the combination of the limiting mechanism and the vertical mechanism to allow the cleaning brush to move into the receiving groove via the limiting block, enabling the cleaning brush to be detached from the body. This allows for individual cleaning or maintenance of the cleaning brush, providing convenience and effectiveness for cleaning and maintenance. Furthermore, the rotating wheel reduces frictional wear between the limiting block and the sliding groove, extending the service life of the limiting block and reducing the cost of limiting the movement of the limiting block and the cleaning brush. Additionally, the vertical mechanism allows for detachable assembly and disassembly of the vertical rod and the cleaning brush, further enhancing the flexibility of cleaning brush assembly and disassembly.

[0004] By utilizing a combination of limiting and vertical mechanisms, the cleaning brush can move into the receiving slot using the limiting block, allowing it to be detached from the machine body for individual cleaning or maintenance. This provides convenience and effectiveness for cleaning and maintenance. Furthermore, the rotating wheel design reduces frictional wear between the limiting block and the sliding groove, extending the service life of the limiting block and lowering the cost of limiting the movement of the limiting block and cleaning brush. The vertical mechanism also allows for detachable assembly and disassembly of the vertical rod and cleaning brush, further enhancing the flexibility of brush assembly and disassembly. However, the design does not consider the labor-intensive issue of manually removing, cleaning, and drying the filter sheets one by one for reuse when the machine is stopped. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a diatomaceous earth filter, which aims to improve the problem of the large workload in the existing technology that does not take into account the manual removal, cleaning and drying of the filter plates one by one under the condition of machine shutdown.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a diatomaceous earth filter, comprising a filter box, a limiting track fixedly connected to the outer wall of the filter box, a motor fixedly connected to the outer wall of the limiting track, a threaded rod provided at the output end of the motor, a threaded block threadedly connected to the outer wall of the threaded rod, a fixed column fixedly connected inside the threaded block, a connecting handle provided on the outer wall of the fixed column, a connecting plate fixedly connected to the outer wall of the connecting handle, a semi-ring fixedly connected to the outer wall of the connecting plate, a filtering mechanism provided on the outer wall of the semi-ring, and an inlet / outlet assembly provided on the outer wall of the filter box, the inlet / outlet assembly being used to control the inlet and outlet of water.

[0007] The above technical solution involves using a drive motor to rotate a threaded transmission rod, which in turn moves a threaded slider and a fixed bracket. This causes the connecting frame to move synchronously along a semi-circular guide rail, allowing the entire filter structure to be moved out of the filter box. Rotating the handle causes the connecting frame, semi-circular guide rail, and filter module to rotate around the axis of the fixed bracket. Ultimately, this allows for one-click removal of the entire filter assembly when the machine is stopped, significantly reducing the amount of manual disassembly work and operation time.

[0008] As a further description of the above technical solution:

[0009] The feeding and discharging assembly includes a water inlet pipe, the outer wall of which is disposed on the inner wall of the filter box, and the outer wall of the filter box is provided with a liquid outlet valve.

[0010] The above technical solution involves adding liquid through an inlet pipe and then discharging the liquid through an outlet valve.

[0011] As a further description of the above technical solution:

[0012] The distance the threaded block moves inside the limiting track is equal to the distance the filter mechanism moves inside the filter box, and the outer surface of the filter mechanism is attached to the inner wall of the filter box.

[0013] Through the above technical solution: when the threaded block is attached to the inner wall on the side closest to the motor, the filter mechanism is completely detached from the inside of the filter box. When the filter mechanism is completely attached to the inner wall of the filter box, the handle and connecting plate are completely attached to the inner wall of the filter box, thus achieving a seal.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the threaded block is slidably connected to the inner wall of the limiting track, and the lower surface of the connecting handle is attached to the upper surface of the threaded block.

[0016] With the above technical solution, when the motor drives the threaded rod to move the threaded block, the outer wall of the threaded block is in contact with the inner wall of the limiting track, so that the threaded block can only move in a straight line and will not rotate.

[0017] As a further description of the above technical solution:

[0018] The semi-rings are provided in four parts and are evenly arranged on the outer wall of the connecting plate. The outer wall of the semi-rings is slidably connected to the inner wall of the filter box.

[0019] The above technical solution involves evenly arranging the filtration mechanism inside the filter box by setting semi-rings on the outer wall of the connecting plate, thereby achieving liquid filtration. The semi-rings fit snugly against the inside of the filter box, resulting in a good seal.

[0020] As a further description of the above technical solution:

[0021] The filtration mechanism includes a frame, the outer wall of which is fixedly connected to the outer wall of a semi-ring, a cotton bag is provided on the outer wall of the frame, a filter sheet is provided on the outer wall of the frame, and a mesh structure is provided on the upper surface of the filter sheet.

[0022] The above technical solution involves the liquid flowing vertically through a cotton bag, filtering the liquid through diatomaceous earth, designing a mesh structure on the filter surface to increase the contact area between the diatomaceous earth and the filter, and setting the cotton bag to use a double-layered interwoven mesh to enhance the fixation ability of the diatomaceous earth and improve the filtration and separation effect.

[0023] As a further description of the above technical solution:

[0024] The cotton bag uses a double-layered interwoven mesh, and diatomaceous earth is placed between the cotton bag and the filter sheet.

[0025] The above technical solution uses a double-layered interwoven mesh in the cotton bag, combined with a mesh structure, to enhance the fixation ability of diatomaceous earth.

[0026] As a further description of the above technical solution:

[0027] The outer wall of the mesh structure is bonded to diatomaceous earth.

[0028] The above technical solution increases the contact area between diatomaceous earth and the filter sheet through the mesh structure.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the starting motor drives the threaded rod to rotate, which in turn moves the threaded block and the fixed column, thereby moving the connecting handle and the connecting plate, which in turn moves the half ring and the filter mechanism. Rotating the connecting handle allows the connecting plate, the half ring, and the filter mechanism to rotate around the fixed column, causing the filter mechanism to detach from the filter box. This allows all the filter mechanisms to be removed at once when the machine is stopped, reducing workload and time consumption.

[0031] 2. In this utility model, when the liquid flows through the cotton bag, it is filtered by diatomaceous earth. The surface of the filter is designed with a mesh structure, which can increase the contact area with the diatomaceous earth. At the same time, the cotton bag adopts a double-layer interlaced mesh, which can improve the fixation ability of the diatomaceous earth, thereby improving the filtration and separation effect.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 3 and Figure 4An embodiment of this utility model provides a diatomaceous earth filter, including a filter box 1. A limiting track 2 is fixedly connected to the outer wall of the filter box 1. A motor 3 is fixedly connected to the outer wall of the limiting track 2. A threaded rod 4 is provided at the output end of the motor 3. A threaded block 5 is threadedly connected to the outer wall of the threaded rod 4. A fixing column 6 is fixedly connected inside the threaded block 5. A connecting handle 7 is provided on the outer wall of the fixing column 6. A connecting plate 8 is fixedly connected to the outer wall of the connecting handle 7. A semi-ring 9 is fixedly connected to the outer wall of the connecting plate 8. A filter mechanism 10 is provided on the outer wall of the semi-ring 9. An inlet / outlet assembly 11 is provided on the outer wall of the filter box 1. The inlet / outlet assembly 11 is used to control the inlet and outlet of water.

[0041] Specifically, the motor 3 drives the threaded rod 4 to rotate, which in turn moves the threaded block 5 and the fixed column 6, thereby moving the connecting handle 7 and the connecting plate 8. The movement of the connecting plate 8 causes the semi-ring 9 to move synchronously, which in turn moves the filter mechanism 10. After the filter mechanism 10 has completely left the interior of the filter box 1, the connecting handle 7 is rotated to make the connecting plate 8, the semi-ring 9, and the filter mechanism 10 rotate around the fixed column 6, so that the filter mechanism 10 leaves the interior of the filter box 1. This achieves the effect of removing all the filter mechanisms 10 at the same time while the machine is stopped, reducing workload and time and effort.

[0042] Reference Figure 1 and Figure 2 The feed assembly 11 includes a water inlet pipe 1101, the outer wall of which is disposed on the inner wall of the filter box 1, and the outer wall of the filter box 1 is provided with a liquid outlet valve 1102.

[0043] Specifically, the liquid is added into the filter box 1 through the inlet pipe 1101, and after filtration is completed, it is discharged through the outlet valve 1102.

[0044] Reference Figure 3 and Figure 4 The distance that the threaded block 5 moves inside the limiting track 2 is equal to the distance that the filter mechanism 10 moves inside the filter box 1, and the outer surface of the filter mechanism 10 is attached to the inner wall of the filter box 1.

[0045] Specifically, when the threaded block 5 is attached to the inner wall on the side closest to the motor 3, the filter mechanism 10 is completely detached from the interior of the filter box 1. When the filter mechanism 10 is completely attached to the inner wall of the filter box 1, the handle 7 and the connecting plate 8 are completely attached to the inner wall of the filter box 1, thus achieving a seal.

[0046] Reference Figure 3 and Figure 4 The outer wall of the threaded block 5 is slidably connected to the inner wall of the limiting track 2, and the lower surface of the connecting handle 7 is attached to the upper surface of the threaded block 5.

[0047] Specifically, when the motor 3 drives the threaded rod 4 to move the threaded block 5, the outer wall of the threaded block 5 is in contact with the inner wall of the limiting track 2, so the threaded block 5 can only move in a straight line and will not rotate.

[0048] Reference Figure 2 There are four semi-rings 9 evenly arranged on the outer wall of the connecting plate 8, and the outer wall of the semi-rings 9 is slidably connected to the inner wall of the filter box 1.

[0049] Specifically, by setting semi-rings 9 evenly on the outer wall of the connecting plate 8, the filter mechanism 10 is evenly arranged inside the filter box 1 to achieve liquid filtration. The semi-rings 9 are in close contact with the inner wall of the filter box 1, thus providing a good sealing effect.

[0050] Reference Figure 2 and Figure 5 The filtration mechanism 10 includes a frame 12, the outer wall of the frame 12 is fixedly connected to the outer wall of the semi-ring 9, a cotton bag 13 is provided on the outer wall of the frame 12, a filter sheet 14 is provided on the outer wall of the frame 12, and a mesh structure 15 is provided on the upper surface of the filter sheet 14.

[0051] Specifically, when the liquid flows vertically through the cotton bag 13, it is filtered through diatomaceous earth. A mesh structure 15 is designed on the surface of the filter plate 14 to increase the contact area between the diatomaceous earth and the filter plate 14. The cotton bag 13 is set to adopt a double-layer interlaced mesh to improve the fixation ability of the diatomaceous earth and improve the filtration and separation effect.

[0052] Reference Figure 5 The cotton bag 13 uses a double-layered interwoven mesh, and diatomaceous earth is placed between the cotton bag 13 and the filter plate 14.

[0053] Specifically, the cotton bag 13 uses a double-layered interwoven mesh, which, together with the mesh structure 15, enhances the fixation ability of the diatomaceous earth.

[0054] Reference Figure 5 The outer wall of the mesh structure 15 is bonded to the diatomaceous earth.

[0055] Specifically, the mesh structure 15 increases the contact area between the diatomaceous earth and the filter sheet 14.

[0056] Working principle: After filtration is completed, start motor 3. Motor 3 drives threaded rod 4 to rotate, which in turn drives threaded block 5 and fixed column 6 to move, thereby driving handle 7 to move. The movement of handle 7 synchronously drives connecting plate 8 to move. The movement of connecting plate 8 drives half ring 9 to move. The movement of half ring 9 drives filter mechanism 10 to move, thereby pulling filter mechanism 10 out of the filter box 1. Rotating handle 7 drives filter mechanism 10 to rotate, thus achieving the effect of removing all filter sheets at the same time when the machine is stopped, reducing workload and time and effort.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
