Description

Technical Field

[0001] The utility model relates to the technical field of filtering and collecting devices, in particular to a printed circuit board film residue filtering and collecting device. Background Art

[0002] The existing patent publication number is CN209490529U, which discloses a printed circuit board film residue filtering and collecting device in the field of filtering and separation technology, including a box body, the box body includes a filter box and a film residue storage box, and the film residue storage box is located on the right side of the filter box, and a screw conveyor and two groups of filter plates are arranged in the inner cavity of the filter box from top to bottom, and the two groups of filter plates are communicated with the film residue storage box. The utility model has a simple structure and a novel design. Through the mutual cooperation of the screw conveyor and the filter plate, the film residue is automatically discharged into the film residue storage box after the film residue waste liquid is filtered, and then the film residue is automatically discharged under the cooperation of the pressure sensor and the electric push rod. At the same time, under the action of the fan, the slide rail and the screw rod, the filter plate can be directly cleaned. The setting of the two groups of filter plates can clean the filter plate without stopping the machine, thereby reducing the number of shutdowns and improving production efficiency.

[0003] However, its structural design is complex, the cost is high, and its closed structure is not convenient for maintenance and cleaning. The cleaning by rotating the auger will cause the membrane to be pressed on the filter screen, resulting in blockage and making it more difficult to clean. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a printed circuit board film residue filtering and collecting device is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A printed circuit board membrane residue filtering and collecting device comprises a filter cabin supported by supporting feet, a filter drum rotatably arranged in the filter cabin, a plurality of filter holes are arranged on the side wall of the filter drum, and a plurality of paddles are fixedly arranged at annular intervals on the side wall of the filter drum, a driving motor for driving the filter drum to rotate is fixedly arranged on the upper end surface of the filter cabin, a synchronous belt assembly is used for transmission between the driving motor and the rotating shaft of the filter drum, a membrane concentration cabin connected to the filter cabin is also arranged on the side of the filter cabin, a drain pipe is fixedly arranged at the bottom of the filter cabin, the upper end of the drain pipe extends into the filter drum, and the drain pipe and the filter drum are connected by a dynamic sealing bearing so that the filter drum can be sealed while rotating relative to the drain pipe.

[0007] Preferably, the bottom plate of the filter chamber is in the form of an upwardly protruding conical boss structure, so that the membrane is not easily wound around the rotating shaft of the filter drum and can be thrown into the membrane concentration chamber more conveniently.

[0008] Preferably, an obliquely arranged guide filter plate is welded and fixed on the inner wall of the filter cabin, and the guide filter plate is used to guide the rotating membrane into the membrane concentration cabin, and the membrane is thrown to the outside by centrifugal force and rotates along the inner wall of the filter cabin, so that it can enter the membrane concentration cabin under the guidance of the guide filter plate, which is convenient for subsequent regular processing.

[0009] Preferably, a plurality of through holes are provided at intervals on the guide filter plate for allowing the filtrate to pass through, so as to form a continuous circulation.

[0010] Preferably, the height of the paddle plate is consistent with the height of the filter drum.

[0011] Preferably, the width of the paddle plate is not less than the radius length of the filter drum.

[0012] The advantages and positive effects of the utility model are: when the mixed liquid is added from above, it rotates under the action of the filter drum, the membrane is thrown outward under the action of centrifugal force and then enters the membrane concentration cabin under the guidance of the guide filter plate, which is convenient for subsequent regular cleaning, and the liquid passes through the filter drum and is discharged from the drain pipe. Compared with the existing design, this structure uses centrifugal force to completely keep the membrane away from the filter hole, avoiding clogging, and is more efficient and reasonable. The open structure is more convenient for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
