Description

Technical Field

[0001] The utility model relates to the technical field of gelatin production, and more specifically to a cotton cake filter for gelatin production. Background Art

[0002] In the process of gelatin production, the flocculated and settled materials need to be filtered to remove impurities in the materials to ensure the purity of the finished gelatin products. The cotton cake filter uses defatted cotton cake as the filter medium, which can effectively remove tiny impurities and particles in the liquid and ensure the purity of the filtrate. Therefore, in the gelatin production process, cotton cake filters are mostly used to filter the flocculated and settled materials.

[0003] The mesh numbers of the existing cotton cake filters are the same. During the filtration process, impurities in the material are easy to clog the filter at the front end, affecting the liquid output and the filtering effect. Therefore, the filter needs to be frequently disassembled for cleaning and maintenance. The existing filter is installed on the frame layer by layer. When disassembling, the front end needs to be completely disassembled before cleaning, which makes the entire cleaning and maintenance process more cumbersome and takes up a lot of time, making it inconvenient to maintain the cotton cake filter.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A cotton cake filter for gelatin production, combined with Figures 1 to 3 As shown, it includes a base plate 1, a front frame 3 and a rear frame 4 are vertically arranged at the front and rear ends of the base plate, connecting rods 5 are respectively arranged on both sides between the front frame 3 and the rear frame 4, an end cover 7 is arranged between the two connecting rods located on the inner side of the rear frame 4, and a plurality of filter plates 8 are arranged between the two connecting rods 5 on the inner side of the end cover 7 for filtering materials.

[0021] A filter screen 13 is provided on the filter plate 8, and the mesh number of the filter screen 13 on the filter plate 8 gradually increases from front to back, that is, the filtration aperture gradually decreases, which avoids clogging of the filter screen during the filtration process and can also improve the filtration effect.

[0022] A pressure plate 6 is provided at the front end of the filter plate 8 for applying pressure to the filter plate. A feed port is provided above the pressure plate 6, and a discharge port is provided at the bottom of the end cover 7. A hydraulic cylinder 10 is provided on the front frame 3. The telescopic rod of the hydraulic cylinder is connected to the outer side of the pressure plate to drive the pressure plate to move toward the filter plate side to achieve material filtering.

[0023] A pressure gauge 12 is provided on the end cover 7 for detecting the pressure applied by the pressure plate. A control box 11 is provided on the bottom plate 1 for controlling the operation of the cotton cake filter. The input end of the control box is connected to the output end of the pressure gauge, and the output end of the control box is connected to the input end of the hydraulic cylinder. The control box controls the action of the hydraulic cylinder according to the pressure detected by the pressure gauge to avoid damage to the cotton cake filter due to excessive pressure.

[0024] The filter plate 8 is detachably arranged on the connecting rod 5 through a connecting mechanism 9. The connecting mechanism 9 includes a lap plate 14 fixedly arranged on both sides of the filter plate 8 and a fixed plate 15 movably arranged at the bottom of the lap plate through a rotating shaft. The centers of the lap plate 14 and the fixed plate 15 are both provided with an arc for fixing the filter plate on the connecting rod. The outer sides of the lap plate 14 and the fixed plate 15 are both provided with a connecting plate 16. A bolt 17 is passed through the two connecting plates 16, and a nut 18 is sleeved on the bolt.

[0025] The bottom end of the bolt 17 is passed through the connecting plate 16 located on the fixing plate 15. A through groove is provided on the outer side of the connecting plate 16 located on the lap plate 14 for the bolt to enter and exit. Limiting plates are provided at the upper and lower ends of the bolt 17 to limit the bolt and prevent it from falling.

[0026] When installing the filter plate, place the filter plate on the connecting rod through the lap plates on both sides, rotate the fixing plates on both sides upwards, make the two connecting plates butt together, pass the upper end of the bolt through the upper connecting plate, and rotate the nut to fix it. When disassembling, loosen the nut to separate the fixing plate from the lap plate, and then the filter plate can be removed.

[0027] A groove 19 is provided on one side of the filter plate 8 facing the pressure plate 6, and a convex rib 20 is provided on the other side of the filter plate 8 to match the groove on the adjacent filter plate. The inner side of the pressure plate 6 is provided with a convex rib 20 to match the groove 19 on the adjacent filter plate 8. The inner side of the end cover 7 is provided with a groove 19 to match the convex rib 20 on the adjacent filter plate 8. The filter plate is positioned by matching the groove and the convex rib to avoid displacement of the filter plate when pressure is applied on the pressure plate, resulting in leakage of material and affecting the filtering effect.

[0028] In order to facilitate the movement of the cotton cake filter, four universal wheels 2 are arranged at the bottom of the bottom plate 1, and locking plates are arranged on the universal wheels to fix the universal wheels.

[0029] When the utility model is working, the material enters the filter plate from the feed port on the pressure plate, and the hydraulic cylinder applies pressure to the pressure plate to filter the material in the filter plate from front to back. Since the mesh number of the filter screen is gradually increased, the filtering accuracy is gradually increased, thereby improving the filtering effect. When cleaning and maintaining the filter plate, the filter plate can be removed by simply opening the nut on the side end of the filter plate, which is convenient for maintenance personnel to operate.
