Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figure 1 and Figure 2 As shown, a filter press device for lithium magnesium silicate production includes a support 1, a filter box 2, a pressure plate 3, and a collection tank 4. The support has a placement trough 5 at its upper end, and a collection port 6 at its bottom. The filter box is placed inside the placement trough and is a hollow structure with an open top. A filter screen 7 is located at its bottom, directly above the collection port. The collection tank is located directly below the collection port. The filter box has a pressure plate and an electric push rod 8 for driving the pressure plate's lifting and lowering movement at its upper end. A gantry frame 15 spanning the filter box is located at the upper end of the support. The electric push rod is installed vertically downwards on the upper part of the gantry frame. The output shaft of the electric push rod is equipped with a connector 9. The pressure plate and the connector are detachably connected. The pressure plate and the filter box cooperate with each other. The electric push rod drives the pressure plate to move downwards, pressing and filtering the material in the filter box. Under the action of the filter screen, the filtrate enters the collection tank through the collection port, achieving the purpose of solid-liquid separation. Since the pressure plate and the connector are detachably connected, and the filter box can be removed from the placement tank, the pressure plate and filter box can be disassembled and cleaned, making it convenient to use.

[0020] Combination Figure 2 and Figure 3 As shown, the lower end of the connector is provided with a positioning groove 10, and the upper end of the pressure plate is provided with a protrusion 11 that matches the positioning groove. The protrusion is embedded in the positioning groove, and the protrusion and the connector are assembled and connected by a positioning pin 12 to realize the detachable assembly connection between the connector and the pressure plate. The positioning pin is threadedly connected to the positioning hole 13 on the connector, and one end of the positioning pin is engaged with the slot 14 on the protrusion. When the positioning pin is tightened, one end of the positioning pin is embedded in the slot to fix the position of the protrusion; conversely, when the positioning pin is removed, the protrusion can be taken out from the positioning groove to disassemble the pressure plate.

[0021] like Figure 1 As shown, in order to improve the stability of the filter box during the filtration process, this embodiment adds a filter box clamping and fixing mechanism. Positioning strips 16 for clamping and fixing the filter box are provided on both the front and rear sides of the filter box. Each positioning strip is slidably connected to the sliding groove 17 provided on the side wall of the gantry frame. Fixing blocks 18 are provided on the outer walls on both sides of the gantry frame. The fixing blocks are located between the two positioning strips and are assembled and connected to them by locking screws 19. After the two positioning strips clamp the filter box, the locking screws can be tightened.

[0022] The working principle of this utility model is as follows:

[0023] like Figures 1 to 3 As shown, before use, place the filter box 2 in the placement slot 5 of the support 1, then slide and adjust the positioning strips 16 on both sides of the filter box 2 to clamp the filter box 2 and tighten the locking screw 19. The two positioning strips 16 are used to fix the filter box 2. After adding the material to be filtered into the filter box 2, start the electric push rod 8 to drive the pressure plate 3 to move downward, squeezing the material in the filter box 2. Under the action of the filter screen 7, the filtrate enters the collection tank 4 through the collection port 6, realizing solid-liquid separation. After use, screw the positioning pin 12 to separate it from the protrusion 11, and screw the locking screw 19 to remove the positioning strips 16. The pressure plate 3 and the filter box 2 can then be removed for regular cleaning and maintenance.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
