Technical Field
[0001] This utility model relates to the field of solid-liquid separation, specifically to an automatic cleaning device for filter press discharge. Background Technology
[0002] A filter press is a device used for solid-liquid separation, commonly used in industry and laboratories. It forces liquid through a filter cloth by applying pressure, causing solids to remain on the cloth to form a filter cake, while the liquid flows out through the cloth. Filter presses are widely used in industries such as chemical, mining, environmental protection, food, and pharmaceuticals. They offer advantages such as effective separation of fine solid particles, simple operation suitable for various processes, and applicability to liquids of varying viscosities. However, they also have some drawbacks, such as relatively slow processing speed and the need for regular maintenance and filter cloth replacement. Therefore, reducing the frequency of filter cloth replacement to save costs is a practical problem that needs to be addressed when using a filter press. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Example 1
[0025] like Figures 1 to 3 As shown, an automatic cleaning device for filter press discharge is provided. This cleaning device is installed and connected to the filter press frame 1 of the filter press. It is used to clean the filter pressing mechanism after filtration. Structurally, the cleaning device can be implemented as follows: a movable support frame 2 is connected to the top of the filter press frame 1. A filter pressing mechanism (the filter pressing structure of a prior art filter press) for filtration of raw materials is installed on the filter press frame 2. Movable guide beams 21 are installed on both sides of the top of the movable support frame 2. A cleaning bracket 3 is movably connected to the movable guide beams 21 via a movable connection structure. A cleaning tank 4 is movably connected to the cleaning bracket 3 and is movably positioned above the filter pressing mechanism via the cleaning bracket 3. A cleaning nozzle for cleaning the filter pressing mechanism is installed at the bottom of the cleaning tank 4.
[0026] In this embodiment, after the raw material is filtered by the existing filter press mechanism, when it is necessary to clean the filter press mechanism, the cleaning tank 4 is controlled to move with the cleaning support 3, so that the filter press mechanism below the cleaning tank 4 is quickly cleaned by the water sprayed from the cleaning nozzle connected to the bottom of the cleaning tank 4.
[0027] Example 2
[0028] Based on Embodiment 1, an electrically controlled drag chain 33 is installed and connected to the cleaning support 3. The drag chain 33 is used to drive the cleaning support 3 to move flexibly along the movable support frame 2 at the top of the filter press frame 1 via a movable connection structure. The movable connection structure includes a movable rack 31 and two movable gears 32. The movable rack 32 is installed and connected to the movable guide beam 21. The two ends of the bottom side of the cleaning support 3 are respectively rotatably connected to the movable gears 32 via a rotating shaft. The two movable gears 32 are engaged with the movable rack 31 in a transmission configuration.
[0029] In this embodiment, when it is necessary to control the horizontal movement of the cleaning bracket 3, the cleaning bracket 3 is moved by controlling the electric drag chain 33. Then, under the action of the meshing and limiting action of the movable gear 32 and the movable rack 31, the cleaning bracket 3 moves horizontally along the movable support frame 2 at the top of the filter press frame 1 through the two movable connecting structures.
[0030] Example 3
[0031] The cleaning tank 4 of this setup is connected to a pump via a pipe, and the pump adds cleaning water to the cleaning tank 4. Simultaneously, a connecting slider 41 is connected to the bottom of the cleaning tank 4, and the connecting slider 41 is movable up and down via a guide rail to the cleaning bracket 3. A connecting pipe is also located at the bottom of the cleaning tank 4, with one end connected to the cleaning tank 4 and the other end passing through the connecting slider 41, with its end used to install a cleaning nozzle.
[0032] The existing filter press mechanism of this setup (to be briefly described) includes several filter press seats 5, which are located below the cleaning nozzle. Each filter press seat 5 is movably connected to the filter press frame 1 via guide rails, and the guide rails control the movement of the filter press seat 5 along the filter press frame 1. The filter press seat 5 is used to pass raw material for filtration, and it has several filtration holes for liquid passage. A filter press block is connected to the filter press seat 5, which is placed in the previous filter press seat to squeeze and filter the raw material in the filter press seat.
[0033] In this embodiment, after each filter press seat 5 in the filter press mechanism completes the filter press operation, the filter press seat 5 is separated by the guide rail and the raw material cake after filter press seat 5 is taken out. In order to avoid the filter press holes in the filter press seat 5 being blocked, the cleaning tank 4 is controlled to move horizontally and vertically on the cleaning support 3, thereby driving the cleaning nozzle connected to the bottom of the cleaning tank 4 to clean the filter press seat 5, so as to avoid the filter holes in the filter press seat 5 being blocked.
[0034] In this regard, the added cleaning device can reduce the frequency of later maintenance and replacement, thereby saving costs.
