Problems solved by technology
At present, the shaking bag is lifted or lowered together with the fixed frame by shaking the handle up or down with manpower by the wire rope, which has the following disadvantages: the operator’s operation is intensive, inconvenient, and consumes a lot of physical strength; the positioning is not accurate; the force is applied Unbalanced, the frame used to fix the filter bag is easy to collide with the inner wall of the fluidized bed, affecting the smoothness of the inner wall of the fluidized bed, etc., and it is also more likely to cause the breakage of the wire rope; the disassembly and installation process of the shaking bag is very laborious

Embodiment Construction
[0041] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.
[0042] In order to achieve the purpose of automatically lifting or lowering the filter bag inside the fluidized bed, to solve the technical problems of the prior art that the manual shaking of the bag is intensive, inconvenient, and physically exhausting, such as Figure 1-3 As shown, the following technical solutions are provided:
[0043] An electric lifting structure for filter bags, applied to lift filter bags 1, comprising,
[0044] The spreader 2 is installed inside the fluidized bed in a liftable manner, and a plurality of filter bags 1 are suspended on the spreader 2;
[0045] A rope 3, one end of the rope 3 is fixedly connected with the spreader 2;
[0046] Also includes,
[0047] The hoist 4 is...

The invention relates to the field of fluidized beds, in particular to a filter bag electric lifting structure. The structure comprises a lifting appliance, which is mounted in a fluidized bed in a lifting mode, wherein multiple filter bags are hung on the lifting appliance; a rope, wherein one end of the rope is fixedly connected with the lifting appliance; a winch, which is fixedly mounted outside the fluidized bed, wherein the other end of the rope is fixedly connected with the output end of the winch; and a locking device, which is fixedly arranged in the fluidized bed and is used for locking the lifting appliance so that the lifting appliance cannot move. The full-automatic bag shaking function is achieved through the winch, the locking device, a guide mechanism and a sensor, and compared with the prior art, manpower is saved.
Description
technical field [0001] The invention relates to the field of fluidized beds, in particular to an electric lifting structure for a filter bag. Background technique [0002] Fluidized bed is one of the important equipment in industrial production, especially in the pharmaceutical industry, mainly used in drying, granulating, coating and other processes. In the above process, the dust particles gradually accumulate on the surface of the filter bag under the updraft of the fluidized bed, which reduces the filtration efficiency of the filter bag, causes the pressure difference inside and outside the fluidized bed to change, and affects the entire experiment and production process. . In addition, it may cause the loss of raw and auxiliary materials, which will affect the yield and inaccurate content, and may also cause the outer surface of the coating to be polluted, affecting the appearance or quality. Therefore, it is necessary to clean the filter bag in time to ensure the smo...
