Description

Technical Field

[0001] This utility model relates to the field of filtration equipment, and in particular to a stirring device for a three-in-one filter. Background Technology

[0002] Industrial filtration often involves processes such as stirring, filtering, washing, and drying, which has led to the development of solid-liquid separation three-in-one filters.

[0003] Currently, the patent with authorization announcement number "CN219922193U" discloses a solid-liquid separation three-in-one filter. The filtration process is as follows: the raw material liquid is injected into the filter tank through the inlet under pressure or vacuum. Nitrogen or compressed air is introduced through the positive pressure port to pressurize the filter, so that the clear liquid flows out from the outlet. The solid filter cake accumulates on the five-layer sintered mesh filter plate. The filter cake is flat during filtration, and the solid-liquid separation effect is good. Washing process: A 360° rotating spray ball is installed below the spray washing port inside the container. Washing liquid is introduced and evenly distributed in the container under the action of the spray ball, realizing internal cleaning of the container and slurry washing of the filter cake. The lifting device makes the stirring blades rise and fall repeatedly in the tank to continuously stir, mixing the filter cake and washing liquid, so that the filter cake is thoroughly washed. Drying process: The filter cake is loosened layer by layer by the stirring blades. High-temperature steam is introduced into the equipment through the jacket cylinder, bottom coil inlet and outlet, stirring shaft and stirring blades. The high-temperature steam inside the stirring shaft and stirring blades can be directly introduced by the steam generator. The high-temperature steam at the inlet and outlet of the jacket cylinder and bottom coil needs to rely on other external equipment to be introduced. After the high-temperature steam is introduced in the above positions, it can evenly heat the filter cake layer. The hot gas is used to heat the wet material under vacuum, which accelerates evaporation and achieves the purpose of rapid and thorough drying.

[0004] However, since high-temperature steam needs to enter the impeller from the stirring shaft, the connection structure between the stirring shaft and the impeller needs to be further defined. Utility Model Content

The structure of the filter and the hollow blade 613 are disclosed in a solid-liquid separation three-in-one filter with the authorization announcement number "CN219922193U", and will not be described in detail here.

[0021] The stirring shaft 5 is cylindrical, and a ring-shaped fixing block 511 is fixed at the lower end of the stirring shaft 5. The stirring mechanism 6 includes a sleeve 611, an inner pull block 612, and several blades 613. The several blades 613 are arranged in an array and slidably inserted into the side wall of the sleeve 611. The sleeve 611 is fixedly located at the bottom of the stirring shaft 5. The inner pull block 612 is inserted into the sleeve 611. A first square slot is provided at the bottom of the stirring shaft 5. The upper end of the inner pull block 612 is fixedly inserted into the first square slot of the stirring shaft 5. The inner pull block 612 abuts against the lower inner end of the stirring shaft 5 and the lower inner end of the sleeve 611 respectively. The stirring shaft 5 is internally connected to the inner pulling block 612, the inner pulling block 612 is internally connected to the sleeve 611, and the sleeve 611 is connected to a plurality of blades 613.

The inner pulling block 612 includes a first block 614, a second block 615, a third block 616, and a fourth block 617 arranged in sequence from top to bottom. The first block 614 and the second block 615 are both square blocks, and the third block 616 and the fourth block 617 are both cylindrical blocks. The first block 614 is inserted into the first square slot. Since it is square, when the stirring shaft 5 drives the blade 613 to rotate, the first block 614 is抵靠 against the first square slot, making the connection more firm. A first square perforation is provided at the middle position of the inner top wall of the sleeve 611, and the upper end of the second block 615 is inserted into the first square perforation. A first chamfer is provided at the opening of the first square slot at the bottom of the stirring shaft 5. A second chamfer is provided between the first block 614 and the second block 615. The second chamfer fits with the first chamfer. By the second chamfer, the firmness of the connection between the first block 614 and the second block 615 is increased. At the same time, the second chamfer fits with the first chamfer, further strengthening the sealing performance of the first square slot. The lower end of the second block 615 and the third block 616 are located at the lower end inside the sleeve 611. Among them, the third block 616 fits with the inner side wall of the sleeve 611, and there is a space between the second block 615 and the inner part of the sleeve 611.
