Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular to a filter press for solid-liquid separation. 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. It is a commonly used solid-liquid separation device. However, when using existing filter presses, the solid material at the filtration point is prone to accumulation, which is not conducive to the collection of solid material and reduces the ease of use of the filter press.

[0003] A filter press for solid-liquid separation is proposed. By spreading and scraping the collected material, the solid material is prevented from accumulating in a fixed position, and the solid material is evenly distributed in the collection tank. This increases the storage capacity of the collection tank for solid material, eliminates the need for frequent cleaning of the solid material in the collection tank, and improves the ease of use of the filter press. Utility Model Content

[0004] The purpose of this invention is to provide a filter press for solid-liquid separation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter press for solid-liquid separation, comprising: The filter press body used for solid-liquid separation has a collection chamber with an opening at the top at the bottom. The leveling assembly includes two positioning frames and positioning plates. The adjacent sides of the two positioning frames are welded to the collection bin. The inner sidewalls of the positioning frames are slidably connected to the positioning plates. The opposite sides of the two positioning plates are welded with connecting plates. The adjacent sides of the two connecting plates are welded with wedge plates for guiding materials. The bottom surface of the wedge plates is welded with a leveling plate that matches the inner cavity of the collection bin. The bottom surface of one of the connecting plates is bolted to the moving part of a linear motor. The linear motor is installed on the outer side wall of the collection bin.

[0006] Preferably, an mounting plate is slidably connected to the bottom surface of the collection chamber, and the top surface of the mounting plate is welded to the main body of the filter press.

[0007] Preferably, a sliding groove is provided on the bottom surface of the mounting plate, and a movable plate is slidably connected to the inner wall of the sliding groove.

[0008] Preferably, a stainless steel protective sleeve is embedded in the side of the movable plate and slidably connected, and the inner wall of the mounting plate is welded to the protective sleeve.

[0009] Preferably, a sliding connection with a limiting plate is embedded in the bottom surface of the protective sleeve, and a threaded sleeve is welded to the top surface of the limiting plate.

[0010] Preferably, the outer curved surface of the threaded sleeve is slidably connected to the inner cavity of the protective sleeve, and the threaded sleeve is threadedly connected to a threaded rod.

[0011] Preferably, both ends of the threaded rod are fixedly connected to connecting shafts, and the sides of the two connecting shafts are rotatably connected to the mounting plate through bearings. One end of the connecting shaft is connected to the output shaft of a rotary motor through a coupling.

[0012] Preferably, the fixed end of the rotary motor is connected to the mounting plate by bolts, and the lower part of the mounting plate is provided with four support plates arranged in an array.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This solid-liquid separation filter press, thanks to its collection chamber design, can collect the solid material filtered out by the main body of the filter press. Simultaneously, thanks to the design of the leveling component, it can level the solid material stored in the collection chamber, preventing solid material falling from the main body of the filter press from accumulating in a fixed position within the collection chamber. A linear motor powers the positioning plate to move along the path of the positioning frame. With the connection of the connecting plate and wedge plate, the leveling plate moves within the collection chamber, leveling the solid material and increasing the storage capacity of the collection chamber. This eliminates the need for frequent cleaning of the solid material in the collection chamber, improving the ease of use of the filter press. This solid-liquid separation filter press uses a rotary motor to power a threaded rod, which rotates. The threaded sleeve moves along the threaded path of the threaded rod. During transmission, the collection chamber slides on the top surface of the mounting plate, facilitating the cleaning of the solid materials collected and stored in the collection chamber. Simultaneously, thanks to the design of the protective sleeve, the threaded rod is protected, preventing solid materials from contacting it and affecting the threaded connection between the threaded rod and the threaded sleeve. The threaded sleeve slides within the inner cavity of the protective sleeve. The threaded sleeve is connected to the moving plate via a limiting plate, improving the structural stability of the filter press's components. Attached Figure Description

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0018] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0019] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0020] Please see Figures 1 to 6 A filter press for solid-liquid separation, in this embodiment including: The filter press body 1 is used for solid-liquid separation. The lower part of the filter press body 1 is provided with a collection chamber 2 with an opening at the top. The filter press body 1 is used to separate solids and liquids. The solid material filtered out by the filter press body 1 can fall into the inner cavity of the collection chamber 2 for collection. Since the filter press body 1 is an existing device, it is not part of the structure to be protected by this utility model and will not be described in detail. When the solid material filtered out by the filter press body 1 falls into the collection chamber 2, the solid material tends to accumulate in a fixed position. This results in some space within the collection chamber 2 not being fully utilized, reducing the storage capacity of the collection chamber 2 for solid material. It also requires frequent cleaning of the solid material in the collection chamber 2, reducing the ease of use of the filter press. Thanks to the design of the leveling component 3, the solid material in the inner cavity of the collection chamber 2 can be leveled, making full use of the internal space of the collection chamber 2, increasing the storage capacity of the collection chamber 2 for solid material, eliminating the need for frequent cleaning of the solid material in the collection chamber 2, and improving the ease of use of the filter press.

[0021] The leveling assembly 3 includes two positioning frames 4 and positioning plates 5. The two positioning frames 4 are welded to the collection bin 2 on adjacent sides. The inner sidewall of the positioning frame 4 is slidably connected to the positioning plate 5. The two positioning plates 5 are welded to the opposite sides of the connecting plates 6. The two positioning frames 4 are in sliding friction contact with the connecting plates 6 on opposite sides. The two connecting plates 6 are welded to the adjacent sides of the connecting plates 7 for guiding materials. The wedge plate 7 is triangular in shape, with a sharp top and a flat bottom surface. The bottom surface of the wedge plate 7 is welded to a leveling plate 8 that is adapted to the inner cavity of the collection bin 2. Both ends of the leveling plate 8 are slidably connected to the collection bin 2. The bottom surface of one of the connecting plates 6 is bolted to the moving part of a linear motor 9. The linear motor 9 is installed on the outer sidewall of the collection bin 2. The fixed end of the linear motor 9 is bolted to the collection bin 2.

[0022] A mounting plate 10 is slidably connected to the bottom surface of the collection chamber 2. The top surface of the mounting plate 10 is welded to the filter press body 1. Sufficient space is reserved between the mounting plate 10 and the filter press body 1 to provide conditions for the placement and movement of the collection chamber 2, so that the collection chamber 2 can be located at the bottom of the filter press body 1 to collect the filtered solid material. A sliding groove is opened on the bottom surface of the mounting plate 10. A movable plate 12 is slidably connected to the inner wall of the sliding groove. A stainless steel protective sleeve 13 is slidably connected to the side of the movable plate 12. The inner wall of the mounting plate 10 is welded to the protective sleeve 13. The bottom surface of the protective sleeve 13 is embedded in the protective sleeve 13. A sliding connection is provided with a limiting plate 14. A threaded sleeve 15 is welded to the top surface of the limiting plate 14. The outer curved surface of the threaded sleeve 15 is slidably connected to the inner cavity of the protective sleeve 13. A threaded rod 16 is threadedly connected to the threaded sleeve 15. A connecting shaft is fixedly connected to both ends of the threaded rod 16. The sides of both connecting shafts are rotatably connected to the mounting plate 10 through bearings. The end face of one of the connecting shafts is connected to the output shaft of a rotary motor 17 through a coupling. The fixed end of the rotary motor 17 is connected to the mounting plate 10 through bolts. Four support plates 11 arranged in an array are provided at the lower part of the mounting plate 10.

[0023] For collection, the solid material filtered out by the filter press body 1 falls into the collection chamber 2 for collection. Thanks to the design of the leveling component 3, the solid material stored in the collection chamber 2 can be leveled, making full use of the internal space of the collection chamber 2. There is no need to frequently clean the solid material in the collection chamber 2, which improves the ease of use of the filter press. The linear motor 9 provides power, which moves the moving part of the linear motor 9, causing the two positioning plates 5 to move along the inner wall of the two positioning frames 4. With the connection of the connecting plate 6 and the wedge plate 7, the leveling plate 8 moves in the inner cavity of the collection chamber 2. During the movement of the leveling plate 8, the solid material in the inner cavity of the collection chamber 2 is leveled, making full use of the space in the collection chamber 2, increasing the collection chamber 2's ability to collect the solid material filtered out by the filter press body 1, and eliminating the need for frequent cleaning of the solid material in the collection chamber 2, which improves the ease of use of the filter press.

[0024] To facilitate cleaning, since the collection chamber 2 is located at the bottom of the filter press body 1, it is inconvenient to clean the solid materials inside the collection chamber 2. The rotary motor 17 provides power, and the output shaft of the rotary motor 17 drives the connecting shaft to rotate, causing the threaded rod 16 to rotate. The threaded sleeve 15 moves along the threaded path of the threaded rod 16. With the connection of the limiting plate 14 and the moving plate 12, the collection chamber 2 can be moved to the top surface of the mounting plate 10 to slide, so that the collection chamber 2 can be moved to the designated position for cleaning of solid materials. At the same time, the threaded sleeve 15 slides along the inner cavity of the protective sleeve 13, and the threaded rod 16 is set in the inner cavity of the protective sleeve 13 to protect the threaded rod 16, preventing the solid materials filtered out by the filter press body 1 from contacting the threaded rod 16 and affecting the threaded connection between the threaded rod 16 and the threaded sleeve 15, thereby improving the structural stability of the filter press components.

[0025] The filter press body 1, linear motor 9, and rotary motor 17 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0026] Working principle When the solid-liquid separation filter press is in use, the solid material filtered out by the filter press body 1 falls into the collection chamber 2 for collection and storage. When flattening, start the linear motor 9 so that the two positioning plates 5 slide along the inner walls of the two positioning frames 4. With the connection of the wedge plate 7 and the two connecting plates 6, the flattening plate 8 slides in the inner cavity of the collection bin 2. During the movement of the flattening plate 8, the solid material in the collection bin 2 is flattened. When cleaning is performed, since the collection chamber 2 is located at the bottom of the filter press body 1 and it is inconvenient to clean solid materials, the rotary motor 17 is started. During the rotation of the output shaft of the rotary motor 17, the connecting shaft is driven to rotate, so that the threaded sleeve 15 moves along the thread path of the threaded rod 16 in the inner cavity of the protective sleeve 13. With the connection of the limiting plate 14 and the moving plate 12, the collection chamber 2 is moved to the designated position for cleaning of solid materials.
