Description

Technical Field

[0001] This utility model relates to the field of pigment production technology, specifically to a filter press for pigment production. 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, widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection. Filter presses are also required in pigment production.

[0003] Currently, when filter presses process pigments, filter cake often adheres to the filter plates and screens when removing the filter cake between the filter plates. The removal of this filter cake is mostly done manually by scraping it off with tools, which increases the workload of workers and also has low efficiency. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1 to 7 A filter press for pigment production, as shown, includes:

[0028] Support frame 1, with multiple filter plates 2 inside the support frame 1, and filter screens 3 at both the front and rear ends of the filter plates 2. The filter screens 3 on the multiple filter plates 2 are in close contact. A support leg 4 is fixed at each of the four corners of the bottom end of the support frame 1.

[0029] Two first U-shaped connecting frames 5 are fixedly installed on both sides of the rear filter plate 2. The bottom end of the first U-shaped connecting frame 5 is fixedly connected to the top end of the support frame 1. A second U-shaped connecting frame 6 is fixedly installed on both sides of the multiple filter plates 2 in the middle. A third U-shaped connecting frame 7 is fixedly installed on both sides of the front filter plate 2. Multiple folding plates 8 are provided between the first U-shaped connecting frames 5, the multiple second U-shaped connecting frames 6 and the third U-shaped connecting frames 7. The two ends of the folding plates 8 are rotatably connected to the first U-shaped connecting frames 5, the second U-shaped connecting frames 6 and the third U-shaped connecting frames 7 through a pivot. A folding crease 9 is provided in the middle of the folding plate 8.

[0030] Multiple movable plates 10 are located on top of multiple filter plates 2 and filter screens 3. Two cleaning scrapers 11 are fixedly provided at the bottom of the movable plate 10. The width of the movable plate 10 is the same as the distance between the two filter plates 2 and filter screens 3 when they are unfolded. The two cleaning scrapers 11 are located on the top of the inner side of the two filter screens 3 after they are unfolded.

[0031] The support frame 1 has a movable slot 12 on both sides of the top. Multiple second U-shaped connecting frames 6 and third U-shaped connecting frames 7 are fixed with a movable block 13 at the bottom. Multiple movable blocks 13 are located inside the movable slot 12. A first multi-stage electric push rod 14 is fixedly installed at the front end inside the movable slot 12. One end of the first multi-stage electric push rod 14 is fixedly connected to the movable block 13 at the bottom of the third U-shaped connecting frame 7.

[0032] A U-shaped support frame 15 is fixedly installed at the top of the support frame 1. The U-shaped support frame 15 is located at the top of multiple movable plates 10. A movable rod 16 is fixedly installed at the middle of the top of the movable plate 10. The top of the movable rod 16 passes through the top of the U-shaped support frame 15 and extends to the top of the U-shaped support frame 15. A connecting plate 17 is fixedly installed at the top of the multiple movable rods 16. Two second multi-stage electric push rods 18 are fixedly installed between the bottom of the connecting plate 17 and the top of the U-shaped support frame 15. The two second multi-stage electric push rods 18 are respectively located on the front and rear sides of the multiple movable rods 16.

[0033] First, pigment slurry is introduced into multiple filter plates 2 and filter screens 3. The filter plates 2 and filter screens 3 then perform pressure filtration and dewatering of the pigment slurry. The pressure filtration and dewatering process is existing technology and will not be described in detail in this application. After pressure filtration is completed, two first multi-stage electric push rods 14 are activated. The two first multi-stage electric push rods 14 drive the multiple filter plates 2 and filter screens 3 to unfold. At this time, multiple folding plates 8 will limit the adjacent two filter plates 2 at equal intervals. Figure 2 As shown, when the two second multi-stage electric push rods 18 are activated, the second multi-stage electric push rods 18 drive the connecting plate 17 to move downward. The connecting plate 17 drives multiple movable rods 16 to move downward. The movable rods 16 drive the movable plate 10 and the cleaning scraper 11 to move downward. The cleaning scraper 11 at the bottom of the movable plate 10 will scrape off the pigment filter cake adhering to the inside of the filter screen 3. In this way, the filter cake adhering between multiple filter plates 2 and filter screen 3 can be scraped off and removed automatically and quickly.

[0034] This invention uses multiple folding plates 8 to equidistantly limit the multiple filter plates 2, and then uses multiple movable plates 10 and cleaning scrapers 11 to scrape off the filter cake adhering to the multiple filter plates 2 and filter screens 3. This makes the removal of filter cake adhering to the filter screens 3 faster and more convenient, effectively reducing the workload of workers and improving the efficiency of filter cake removal. This embodiment specifically solves the problem in the prior art that when a filter press is used to process pigments, filter cake often adheres to the filter plates and filter screens when removing the filter cake between the filter plates. The removal of these filter cakes is mostly done manually by using tools to scrape them off, which increases the workload of workers and has low efficiency.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
