Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and more specifically, to a washable filter press. 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. Filter presses were first used in chemical production and are now widely used in industries such as chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics, and environmental protection.

[0003] However, there are various types of filter presses in the existing technology. For example, utility model patent CN212491740U relates to a hydraulic continuous filter press. This utility model includes a bottom bracket, a push plate and several filter plates are installed on the upper side of the bottom bracket, side frames are provided on both sides of the filter plates, a housing is provided at one end of the side frames and the bottom bracket, a cylinder liner is installed at one end of the housing, a primary telescopic cylinder is installed inside the cylinder liner, a secondary telescopic cylinder is embedded inside the primary telescopic cylinder, a tertiary telescopic rod is embedded inside the secondary telescopic cylinder, a push rod is connected to the end of the tertiary telescopic rod, the right end of the push rod is connected to the push plate, and the left end of the push rod is embedded inside the housing. A hydraulic pump is installed on the upper side of the housing, and an oil pipe is connected between the hydraulic pump and the primary telescopic cylinder. This hydraulic continuous filter press occupies a small volume and has a long stroke.

[0004] Although this filter press has a small footprint and a long stroke, enabling it to meet the requirements of long-stroke high-pressure filtration, it lacks a self-cleaning function. This makes it difficult to clean impurities and particles from the filter plates in a timely manner, resulting in solid particles adhering to the filter cloth and affecting the filtration effect. Furthermore, manual cleaning is inefficient and increases the labor intensity for workers. To avoid this, it is essential to design a washable filter press. Utility Model Content

The present invention provides the following embodiments.

[0028] like Figure 1 , Figure 2 as well as Figure 7 As shown, this is a structural schematic diagram of the washable filter press in this embodiment. The filter press in this embodiment includes a support vertical plate 1, and two mounting beams 2 are fixedly connected between the two support vertical plates 1. The two mounting beams 2 are symmetrically distributed, and a number of filter plates 3 are arranged between the two mounting beams 2. Each filter plate 3 is provided with two symmetrical locking pieces 25, and the locking pieces 25 can slide on the two mounting beams 2. A slide rail 29 is fixedly connected to the mounting beam 2. An adjusting seat 30 is slidably installed on the surface of the slide rail 29, and the adjusting seat 30 can adjust the position of the locking pieces 25. During the cleaning process of the filter plate 3 of the filter press, the locking pieces 25 are locked by the adjusting seat 30 installed on the slide rail 29, so that the horizontally sliding adjusting seat 30 drives the filter plate 3 to be cleaned to move and move the filter plate 3 into the cleaning area.

[0029] like Figure 3 , Figure 4 as well as Figure 5As shown, in this embodiment, brackets 4 are fixedly connected to both vertical support plates 1. Two symmetrical mounting frames 5 are slidably installed between the two brackets 4. Movable seats 6 are raised and lowered inside the mounting frames 5. Two symmetrically distributed connecting columns 7 are fixedly connected between the two movable seats 6. Two mounting rods 8 are fixedly connected to the bottom of the connecting columns 7. A cleaning brush plate 10 is fixedly connected to one end of the mounting rod 8 through a fixing frame 9. The surfaces of the two symmetrical cleaning brush plates 10 that are close to each other are provided with bristles 11. Multiple nozzles 13 are provided through the fixing frame 9, and the nozzles 13 are set on the mounting branch pipe 12. When a single filter plate 3 to be cleaned moves to the area below the two mounting frames 5... After cleaning the filter plate 3, two movable seats 6 drive two connecting columns 7 to rise and fall. Using the connected mounting rod 8, two symmetrically distributed cleaning brush plates 10 move up and down, so that the two cleaning brush plates 10 are located on both sides of the filter plate 3. At the same time, the installed mounting branch pipe 12 will transport clean water, which will be rinsed on the filter plate 3 through multiple installed nozzles 13. With the setting of the brush bristles 11, the up and down moving brush bristles 11 brush both sides of the filter plate 3, thereby cleaning the impurities on the filter plate 3 to ensure the filtration effect of the filter plate 3.

By controlling the servo motor 15, one of the screws 14 is driven to rotate through the output end of the servo motor 15. After being positioned and guided by the guide rod, the rotating screw 14 causes the movable seat 6 to move up and down by utilizing the sliding fit between the screw 14 and the movable seat 6. Furthermore, by utilizing the two pulleys 16 and the belt drive, the other screw 14 is driven to rotate synchronously.

[0032] like Figure 4 as well as Figure 6 As shown, in this embodiment, two connecting plates 19 are fixedly connected between the two mounting frames 5.
