Description

Technical Field

[0001] The utility model relates to the technical field of coating production equipment, in particular to a coating production filtering device with multi-stage screening. Background Art

[0002] Various solid particle impurities may be mixed in during the production process, such as dust, sand, and inadequately dispersed pigment agglomerates. To ensure the purity of the coating, it is usually necessary to filter the coating to prevent impurities from affecting the appearance and performance of the coating.

[0003] However, existing paint filtering devices often only use a single-layer filtration method, which results in the overall filtration effect being unsatisfactory during the entire filtration process. In addition, when the filter screen of the equipment is clogged or the equipment needs to be cleaned and maintained, it is usually necessary to stop the machine to perform the corresponding processing operations, which greatly reduces the operating efficiency.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] like Figure 1-Figure 3 As shown, the utility model proposes a coating production filtering device with multi-stage screening, which includes an operation box 1, an installation column 10 is arranged in the operation box 1, and a plurality of filter components 2 are movably arranged at equal intervals on the installation column 10, and a plurality of first slots 12 are provided on the back side of the operation box 1 corresponding to the positions of the plurality of filter components 2, and a plurality of motors 3 are arranged on one side wall of the operation box 1, and the plurality of motors 3 respectively correspond to the plurality of filter components 2, and the corresponding motors 3 are connected to the filter components 2 through a chain 30 for transmission; a plurality of second slots 13 are provided on the side wall of the operation box 1 at positions corresponding to the array of transmission teeth 23, and gears 31 are provided on the transmission ends of the plurality of motors 3, and the gears 31 are connected to the transmission teeth 23 through the chain 30 for transmission, and the chain 30 is inserted in the second slot 13.

[0024] like Figure 4-Figure 5 As shown, in the filter assembly 2, a bearing 24 is arranged in the mounting sleeve 20, and the bearing 24 is arranged on the mounting column 10. A pair of connecting handles 21 are symmetrically arranged on the outer wall of the mounting sleeve 20. A filter frame 22 is arranged on the side of the two connecting handles 21 away from the mounting sleeve 20, and several filter frames 22 on the side of the back plate of the working box 1 pass through the first slot 12 and are located on the outside of the working box 1. A circle of transmission teeth 23 is also arranged on the mounting sleeve 20, and the transmission teeth 23 are located below the connecting handles 21; the apertures of the several filter frames 22 decrease successively from top to bottom.

[0025] like Figure 6As shown, a discharge port 14 is provided at the lower part of the side of the working box 1 away from the second slot 13, and a pair of slide grooves 15 are provided on the bottom plate of the discharge port 14. A loading box 16 is movably provided in the discharge port 14, and the loading box 16 is located below the filter frame 22 inside the working box 1. A pair of slide rails 17 are provided at the bottom of the loading box 16, and the slide rails 17 are movably provided in the slide grooves 15. The loading box 16 is convenient for collecting the filtered paint, and the movable setting of the loading box 16 is convenient for unloading; a lower hopper 11 is provided on the top of the working box 1, and the lower hopper 11 is located above the filter frame 22 inside the working box 1; an observation window 110 is provided on the front of the working box 1, and a transparent plate 111 is provided in the observation window 110 for convenient observation of the filtering condition inside the working box 1; a pair of mounting shells 18 are provided at the lower part of the back of the working box 1, and a dirt tray 19 is movably provided between the two mounting shells 18 for collecting and cleaning the dirt generated by the filter frame 22.
