Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter press technology, specifically a plate and frame filter press. Background Technology
[0002] A filter press is an intermittent filtration device for solid-liquid separation of suspensions. It is widely used in industries such as chemical, petroleum, dye, metallurgy, and environmental protection. The filter press mainly uses a feed pump to transport the liquid material to be filtered into each filter chamber. The filter medium forms filter residue on the filter cloth until the filter chamber is filled and a filter cake is formed.
[0003] According to the patent application website (authorization announcement number: CN 212283040 U), this utility model relates to a plate and frame filter press, specifically to the technical field of filter presses. It includes a filter press frame, a liquid collection tank installed below the frame, and a filter device mounted on the tank. The filter device includes a mounting plate and a filter screen. The mounting plate is interlocked into the liquid collection tank, and the frame is equipped with a locking element for locking the mounting plate. The mounting plate has an installation opening, and the filter screen is installed in the installation opening. This utility model, through the filter device, performs secondary filtration on the liquid after solid-liquid separation, further filtering and removing solid particles from the liquid, thereby improving the quality of the recovered liquid.
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In the process of using this utility model, during the solid-liquid separation of the suspension, the separated liquid falls from the filter press frame into the mounting plate on the liquid collection tank. The filter screen in the mounting plate further performs secondary fine filtration on the liquid, further removing solid particles from the liquid. The filtered liquid enters the liquid collection tank for collection. In actual use, because the discharge box of this device is always open, the filtered liquid raw material cannot be evenly introduced into the liquid collection tank during the filtration process, which can easily lead to the accumulation of solid impurities and cause accidents such as overflow. At the same time, when cleaning the filtered solid impurities, the filter plate needs to be removed as a whole, which increases the workload of the operator. Therefore, it is necessary to improve the plate and frame filter press to solve the above problems. Utility Model Content

[0032] Furthermore, the slider 817 is fixedly connected to the filter plate 814, and the connecting box 816 is provided with a groove at the corresponding position of the slider 817, and the slider 817 is slidably connected inside the groove.

[0035] Example 2:
[0036] Based on Embodiment 1, in the prior art, when cleaning the filtered solid impurities, the entire filter plate needs to be removed, increasing the workload for workers. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 6 Furthermore, in conjunction with Embodiment 1, the adjusting feeding mechanism 9 includes an electric telescopic rod 91, which is fixedly connected to the back of the discharge box 7.

[0038] In actual operation, when this device is used, the operator first places the raw material to be filtered inside the chamber plate frame 5. The hydraulic cylinder 4 is then activated to start the filtration process. Under gravity, the filtered liquid raw material is introduced into the collection tank 6 through the discharge box 7. The electric telescopic rod 91 is activated, causing the toothed plate 92 to slide inside the guide rail 93. In conjunction with the gear 95, the guide plate 94 rotates inside the discharge box 7. The filter plate 814, in conjunction with the baffle 815, filters the liquid entering the collection tank 6. The liquid raw material is filtered by the operation of the motor 811, which, together with the rotating shaft 812, causes the cam 813 to rotate, thereby moving the filter plate 814. With the help of the first spring 818, the slider 817 slides inside the connecting box 816, thus realizing the up-and-down reciprocating motion of the filter plate 814. After filtration is completed, the operator pulls the slide plate 824. The movement of the slide plate 824, together with the second spring 826, causes the locking block 825 to move, which, together with the fixing plate 823, realizes the limiting and installation between the cover plate 821 and the liquid collection tank 6.
