[0039] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0040] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0041] like Figures 1 to 10As shown, a filter press device includes a movable component 1, which includes a movable frame 11. A filter press component 2 is connected to the movable frame 11. The filter press component 2 includes a liquid collection housing 21 connected to the movable frame 11 and a filter press housing 22 connected to the inner side of the liquid collection housing 21. The filter press housing 22 is connected to a filter hole 221, which is used to communicate with the inner cavity of the filter press housing 22 and the liquid collection housing 21. A filter press drive 23 is connected inside the filter press housing 22, which is used to filter the raw material to be filtered inside the filter press housing 22.

[0042] In this embodiment, the device adopts an integrated design of the moving component 1 and the filter press component 2, with the moving frame 11 serving as a supporting structure, enabling the entire filter press device to move flexibly and be quickly deployed between different production areas or process flows. Simultaneously, the tight integration of the liquid collection shell 21 and the filter press shell 22 reduces space occupation and allows for the simultaneous separation of filter liquid and waste. The design of the filter press drive 23 allows for precise pressure control during the filter press process, ensuring the filter press effect, avoiding raw material loss or equipment damage due to excessive pressure, and improving the stability and controllability of the production process.

[0043] In some embodiments, the lower end of the liquid collection housing 21 is connected to a liquid outlet port 211, and a switch valve 212 is connected to the liquid outlet port 211; the lower end of the filter press housing 22 is connected to a discharge port 222, and the upper end of the filter press housing 22 is connected to a feed port 223.

[0044] In this embodiment, the liquid outlet port 211 and the matching switch valve 212 connected to the lower end of the liquid collection housing 21 are designed to allow the liquid separated during the filtration process to be discharged quickly and centrally, avoiding liquid accumulation within the device and ensuring the continuity and efficiency of the filtration operation. The flexible control of the switch valve 212 allows the liquid outlet port 211 to be opened or closed as needed, facilitating operation and maintenance. The feed port 223 located at the upper end of the filter press housing 22 facilitates the rapid and accurate feeding of the raw material to be filtered into the filter press housing 22, improving loading efficiency. Simultaneously, the discharge port 222 connected at the lower end allows the filtered solid material to be smoothly discharged, facilitating subsequent processing or collection; the entire feeding and discharging process is smooth and efficient.

[0045] In addition, the installation of a heating element at the discharge port 222 to heat and melt solid substances and discharge them should fall within the scope of protection of this application.

[0046] In some embodiments, the filter press housing 22 is funnel-shaped, the filter holes 221 are located on the inclined surface of the funnel-shaped filter press housing 22, and the filter press drive 23 includes a spiral rod 231 rotatably connected inside the funnel-shaped filter press housing 22, the spiral rod 231 being correspondingly arranged with the funnel-shaped filter press housing 22.

[0047] In this embodiment, the filter press housing 22 is designed in a funnel shape. Its inclined surface helps the raw material to be filtered to slide down naturally under gravity. Simultaneously, the filter holes 221 located on the inclined surface allow the liquid to flow more smoothly through the filter holes 221 into the collection housing 21, while the solid material gradually accumulates at the bottom of the funnel due to gravity, facilitating subsequent discharge. This design significantly improves the efficiency and effect of solid-liquid separation. The spiral rotor 231 in the filter press drive 23 is rotatably connected inside the funnel-shaped filter press housing 22 and is configured to correspond to the shape of the funnel. During rotation, the spiral rotor 231 can uniformly apply pressure to the raw material inside the filter press housing 22, ensuring a uniform filtration process and avoiding uneven filtration or filter hole blockage caused by excessive or insufficient local pressure. The rotation of the spiral rotor 231 not only provides the pressure required for filtration but also promotes the flow of material within the filter press housing 22 through its spiral structure, helping to reduce material residue within the housing and improve the utilization rate of the raw material. At the same time, this design also facilitates the discharge of solid materials by rotating the spiral rod 231 after the filter press is completed, further reducing residue.

[0048] In some embodiments, the lower end of the funnel-shaped filter press housing 22 is connected to a port connecting rod 224, and the lower end of the spiral rotating rod 231 is rotatably connected to the port connecting rod 224.

[0049] In this embodiment, the port connecting rod 224 connected to the lower end of the funnel-shaped filter press housing 22 provides a stable support point for the spiral rotating rod 231, ensuring that the spiral rotating rod 231 remains stable during rotation and avoiding uneven filtration or equipment damage caused by shaking or deviation. This design allows the spiral rotating rod 231 to be accurately positioned at the center of the filter press housing 22, optimizing the filtration effect. In addition, the port connecting rod 224 can also fix the heating component. Since the heating component is a well-known technical means, it will not be described in detail here.

[0050] In some embodiments, a rotating rod bearing 225 is connected to the upper end of the filter press housing 22, and the spiral rotating rod 231 is rotatably connected to the filter press housing 22 through the rotating rod bearing 225.

[0051] In this embodiment, by providing a rotating shaft bearing 225 at the upper end of the filter press housing 22, the spiral rotating shaft 231 can achieve stable and low-friction rotation under the support of the rotating shaft bearing 225. This design reduces energy loss of the spiral rotating shaft 231 during rotation, improves the filter press drive efficiency, and at the same time reduces heat and wear caused by friction, extending the service life of the equipment.

[0052] In some embodiments, the upper end of the spiral rod 231 is connected to a rotating gear 232, and the filter press drive 23 includes a drive motor 233 connected to the movable frame 11 and a motor gear 234 connected to the drive motor 233. The motor gear 234 is geared to the rotating gear 232.

[0053] In this embodiment, by connecting a rotor gear 232 to the upper end of the helical rotor 231 and a motor gear 234 to the drive motor 233, and achieving gear connection between the two, this design realizes efficient and precise power transmission. Gear transmission has the characteristics of high transmission efficiency and accurate transmission ratio, which can ensure that the power of the drive motor 233 is accurately transmitted to the helical rotor 231, realizing precise control of its speed and direction.

[0054] In some embodiments, an auxiliary gear 235 is rotatably connected to the movable frame 11. The auxiliary gear 235 is located on one side of the motor gear 234 and on the side away from the rotating rod gear 232.

[0055] In this embodiment, an auxiliary gear 235 is rotatably connected to the movable frame 11 and positioned on the side of the motor gear 234 away from the rotating gear 232. This arrangement optimizes the structure of the gear transmission system. The auxiliary gear 235 serves as a transition and support, making the force transmission between the motor gear 234 and the rotating gear 232 more uniform, reducing vibration and noise caused by uneven gear force, and improving the overall stability of the transmission system.

[0056] In some embodiments, the movable component 1 includes two symmetrically arranged bases 12 and a seat rod 13 connected between the two bases 12, and the movable frame 11 is connected to the seat rod 13.

[0057] In this embodiment, the movable component 1 is composed of two symmetrically arranged bases 12 and a support rod 13 connecting the two. This design provides a stable support structure. The symmetrical layout allows the bases 12 to evenly distribute the pressure from the filter press and the material above, enhancing the stability of the overall structure and reducing the risk of deformation or damage caused by uneven stress.

[0058] In some embodiments, the seat rod 13 includes a threaded seat rod 131 and a guide seat rod 132. The threaded seat rod 131 is threadedly connected to the movable frame 11, and the guide seat rod 132 is slidably connected to the movable frame 11.

[0059] In this embodiment, the threaded connection between the threaded seat rod 131 and the movable frame 11 allows the user to precisely adjust the height of the movable frame 11 by rotating the threaded seat rod 131. This adjustment method is highly accurate and repeatable, ensuring that the filter press maintains stable operation under different height requirements and meets the filter press height requirements of different processes.

[0060] In some embodiments, a movable motor 14 is connected to the base 12, a movable gear 15 is connected to the movable motor 14, a seat gear 16 is connected to the movable gear 15, and the seat gear 16 is connected to the threaded seat 131.

[0061] In this embodiment, by connecting a movable motor 14 to the base 12 and using the movable motor 14 to drive the movable gear 15, which in turn drives the seat rod gear 16 to rotate, the threaded seat rod 131 is rotated. This design achieves automated height adjustment of the movable frame 11. Operators do not need to manually rotate the threaded seat rod 131; they can easily adjust the height simply by controlling the movable motor 14, greatly improving the convenience and efficiency of operation.

[0062] Example 1:

[0063] First, place the two symmetrically arranged bases 12 on a flat, stable ground or work platform, ensuring that the bases 12 are placed horizontally and the spacing meets the design requirements.

[0064] Then, the seat rod 13 is connected between the two bases 12. The seat rod 13 consists of a threaded seat rod 131 and a guide seat rod 132. During installation, the two ends of the threaded seat rod 131 and the guide seat rod 132 are fixedly connected to the corresponding bases 12 to ensure a firm connection and avoid loosening or shaking.

[0065] Next, the moving motor 14 is installed on the base 12, and the moving motor 14 is securely fixed in the designated position on the base 12 using suitable fasteners such as bolts and nuts. The moving gear 15 is installed on the output shaft of the moving motor 14, ensuring that the moving gear 15 and the output shaft of the moving motor 14 are tightly fitted without relative slippage.

[0066] Next, the seat gear 16 is installed at one end of the threaded seat rod 131, so that the seat gear 16 and the moving gear 15 are connected, ensuring that the meshing depth and clearance between the gears meet the standards, so as to ensure the smoothness and stability of power transmission.

[0067] Finally, connect the movable frame 11 to the seat rod 13. The movable frame 11 is threadedly connected to the threaded seat rod 131 and slidably connected to the guide seat rod 132. During installation, pay attention to the direction and accuracy of the thread engagement to ensure that the movable frame 11 can move smoothly along the threaded seat rod 131 and the guide seat rod 132. At the same time, an appropriate amount of lubricant, such as lubricating oil or grease, can be applied to the sliding connection between the movable frame 11 and the guide seat rod 132 to reduce frictional resistance.

[0068] Preferably, the liquid collecting housing 21 is mounted on the movable frame 11, and the connection between the liquid collecting housing 21 and the movable frame 11 is ensured to be firm and well-sealed through welding, bolting, or other suitable fixing methods to prevent liquid leakage. The filter press housing 22 is installed inside the liquid collecting housing 21, and a reliable connection method is also used to ensure the stability and sealing of the connection between the two. The filter press housing 22 is funnel-shaped. During installation, attention should be paid to its installation direction to ensure that the filter hole 221 is located on the inclined surface of the funnel-shaped filter press housing 22, and that the filter hole 221 can accurately communicate with the inner cavity of the filter press housing 22 and the liquid collecting housing 21. A discharge port 222 is installed at the lower end of the filter press housing 22, and a feed port 223 is installed at the upper end, ensuring that the connection between the port and the filter press housing 22 is tight and there is no risk of leakage. A liquid outlet port 211 is connected to the lower end of the liquid collecting housing 21, and a switch valve 212 is installed on the liquid outlet port 211. The switch valve 212 is ensured to be correctly installed and can be flexibly opened and closed to control the flow of liquid. A port connecting rod 224 is installed at the lower end of the funnel-shaped filter press housing 22, and the lower end of the spiral rod 231 is rotatably connected to the port connecting rod 224. A bearing or other rotating component can be used to achieve this rotatable connection, ensuring that the spiral rod 231 can rotate freely on the port connecting rod 224. Simultaneously, a rotating rod bearing 225 is installed at the upper end of the filter press housing 22, allowing the spiral rod 231 to be rotatably connected to the filter press housing 22 via the rotating rod bearing 225, ensuring stable and smooth rotation of the spiral rod 231 within the filter press housing 22. A rotating rod gear 232 is installed at the upper end of the spiral rod 231, ensuring a secure connection between the rotating rod gear 232 and the spiral rod 231 without any loosening. A drive motor 233 is installed on the moving frame 11, and a motor gear 234 is installed on the output shaft of the drive motor 233, enabling gear engagement between the motor gear 234 and the rotating rod gear 232. The gear meshing is adjusted to ensure that power is effectively transmitted from the drive motor 233 to the spiral rod 231. The auxiliary gear 235 is rotatably connected to the movable frame 11. The auxiliary gear 235 is installed on the side of the motor gear 234 and located away from the rotating rod gear 232. The auxiliary gear 235 can play the role of auxiliary support and stabilization of the gear transmission system. During installation, it is necessary to ensure that the auxiliary gear 235 can rotate flexibly and that the positional relationship between it and the motor gear 234 meets the design requirements.

[0069] The specific implementation method of this application is as follows:

[0070] The drive motor 233 is started. The drive motor 233 is connected to the rotating rod gear 232 through the motor gear 234, which drives the spiral rotating rod 231 to rotate inside the filter press housing 22. Since the filter press housing 22 is funnel-shaped, the spiral rotating rod 231 is correspondingly arranged to the funnel-shaped filter press housing 22. The rotation of the spiral rotating rod 231 will apply downward pressure to the chemical raw material inside the filter press housing 22. At the same time, as the spiral rotating rod 231 rotates, the raw material will be continuously squeezed and moved towards the discharge port 222.

[0071] During the pressure filtration process, the squeezed liquid enters the liquid collection shell 21 from the filter housing 22 through the filter holes 221. Due to the filtering effect of the filter holes 221, only liquid can pass through, while solid particles are retained in the filter housing 22, thereby achieving solid-liquid separation.

[0072] When the liquid in the collection housing 21 reaches a certain amount, the switch valve 212 is opened, and the liquid is discharged from the collection housing 21 through the liquid outlet port 211. The discharged liquid can be collected into a designated container for further processing or storage.

[0073] In addition, to transport the filtered liquid to the appropriate location, the moving motor 14 on the base 12 is activated. The moving motor 14 drives the moving gear 15 to rotate, and the moving gear 15, through gear connection with the seat rod gear 16, drives the threaded seat rod 131 to rotate. Since the moving frame 11 is threadedly connected to the threaded seat rod 131, the moving frame 11 moves along the threaded seat rod 131 and the guide seat rod 132 while the threaded seat rod 131 rotates, thereby realizing the movement of the entire filter press device. During the movement, attention should be paid to observing the direction of movement and stability of the device to avoid collisions with surrounding equipment or objects. When the chemical raw material in the filter press housing 22 has been filtered and the solid particles have been fully compressed, the discharge port 222 is opened. Through the continued rotation of the screw rod 231, the filtered solid material is pushed out from the discharge port 222 and collected into a designated container or location for subsequent processing.

[0074] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0075] The device adopts an integrated design of moving parts and filter press components, with the moving frame serving as the supporting structure, allowing the entire filter press unit to move flexibly and be quickly deployed between different production areas or process flows. Simultaneously, the tight integration of the liquid collection shell and the filter press shell reduces space occupation. The filter press drive design allows for precise pressure control during the filtration process, ensuring filtration efficiency and preventing raw material loss or equipment damage due to excessive pressure. This improves the stability and controllability of the production process and enables simultaneous separation of filtration liquid and waste. It solves the problem of existing filter press technologies having a simple structure and the inability to perform filtration and cleaning operations simultaneously during the filtration process, resulting in relatively low filtration efficiency.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
