Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filtering equipment, in particular to a filtering device. Background Art
[0002] The filter device is a mechanical separation device widely used in chemical production, and is mainly used in the separation process of heterogeneous liquid-solid mixtures. The current filter devices are mainly filter element type, stacking filter, mesh type, and centrifugal type. The structure of these devices is relatively complex, and they are mainly fixed installation structures. They have neither rotation function nor are easy to move. The filter device is usually installed in the same workshop as the reaction and crystallization equipment, and is often used as a supporting device for fixed products or fixed equipment. However, in the process of unloading the filtered product and cleaning the filter medium, a lot of disassembly work is required for the equipment, which is not only labor-intensive but also occupies a large area. Chemical plants usually use organic solvents when cleaning the filter device. If the disassembly and cleaning operations are frequently performed in the comprehensive workshop, it is very easy to collide and produce sparks, which poses a great safety hazard. On the other hand, for some small and medium-sized chemical companies, their production sites are mainly rented factories, and fixed filter devices occupy a large area, so a large area of factory buildings is required. Moreover, each reaction and crystallization equipment needs to be equipped with a dedicated filter device, which increases the investment in equipment and the production cost. Utility Model Content

[0039] The working principle of the utility model is:
[0040] Open valve 25, and the non-homogeneous liquid-solid mixture is added to the filter from the material feed pipe 24 of the filter cover 2 through an external pipe. Under the action of gravity, the liquid mother liquor flows through the filter plate 31 to the position of the lower cover 3 and flows out of the filter from the discharge pipe 32, and flows out from the pipe 34 to the receiving container through the elbow 33 and valve 25. During the filtering process, the filter is shaken or rotated left and right by operating the worm gear reducer 6, and the filtering situation is observed from the window 22 of the filter cover 2 (one of the two windows is used for observation, and the other is used to provide light source). Of course, in order to have a better filtering effect, nitrogen can be introduced at the air pipe joint 23 and then rotated. The other air pipe joint can be connected to a pressure gauge. Under the action of nitrogen pressure, a pressure difference is formed on both sides of the filter plate 31, so that the filtering effect is better.
[0041] When a batch of materials is filtered, disconnect the material pipeline, close the valve at the feed pipe 24, move the filter device to the product unloading area, open the upper cover 2, shake or rotate the filter left and right to pour the solid material into the receiving tray, then install the upper cover 1 and move the filter device to the cleaning area. After moving to the cleaning area, rotate the filter so that the discharge port (discharge pipe) faces upward and the feed port (feed pipe) faces downward, connect the cleaning solvent from the discharge port, and then adjust the filter to a vertical position so that the solvent is evenly distributed in the gap between the sintering plate and the lower cover for reverse flushing. Then detect the cleaning solvent flowing out of the feed port to determine the washing condition until the cleaning standard is met.
[0042] After cleaning, the filter device is moved to the storage area outside the production workshop for next filtration use.
