DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Any coating that uses water as a solvent or dispersion medium can be called a water-based coating. Based on the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings made from natural substances or minerals and petrochemical water-based coatings made from synthetic resins. Water-based coatings include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products. In addition, there are water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. In the production of water-based coatings, water-based coatings need to be filtered to ensure product quality, improve construction effects, reduce environmental pollution, and enhance product competitiveness.

[0023] See also Figure 1-Figure 5 As shown, the present embodiment provides a water-based paint filtering device, including a supporting base 1, a supporting frame 2 and an operating barrel 3, the upper surface of the supporting base 1 is fixedly connected to the lower surface of the supporting frame 2, the inner wall of the supporting frame 2 is fixedly connected to the outer wall of the operating barrel 3, considering that when the existing water-based paint filtering device filters the water-based paint, the filter screen may be blocked by impurities, affecting the filtration speed and effect, and the filtration may not be sufficiently uniform, and the quality of the filtered water-based paint is not high, therefore, the details are as follows: a filtering mechanism 4 is rotatably connected inside the operating barrel 3, the filtering mechanism 4 includes a mounting bracket 41 that rotates inside the operating barrel 3, a support rod 411 passes through the center of the upper surface of the mounting bracket 41, and a plurality of frame rings 412 are fixedly connected to the outer wall of the mounting bracket 41, and filter elements are movably arranged inside the plurality of frame rings 412, and a shaking mechanism for supporting the shaking of the filter element is provided between the inner wall of the mounting bracket 41 and the outer wall of the support rod 411.

[0024] The improvement of this embodiment is that:

[0025] In the water-based paint filtering device, a plurality of filter elements are provided to perform multi-layer filtration on the water-based paint, thereby improving the filtering effect; and a shaking mechanism is provided so that the filter element can shake horizontally and vertically by centrifugal force during rotation, without causing the filter screen to be blocked and affecting the filtering speed.

[0026] Taking into account that the water-based paint needs to be filtered evenly to improve the filtering effect, the mounting bracket 41 is a frame structure with a cross-shaped top, and the shaking mechanism includes a plurality of grooves 413 opened on the inner wall of the mounting bracket 41 and a limiting groove 4111 opened on the outer wall of the support rod 411, and one of the filter elements is movably provided between the relative grooves 413 and the limiting groove 4111, and the moving directions of the two adjacent filter elements are opposite. By setting the moving directions of the two adjacent filter elements to be opposite, the water-based paint can be shaken laterally and longitudinally respectively during filtering, so that the water-based paint can be filtered more evenly and fully.

[0027] In order to achieve the shaking of the filter element, a shaking gap is formed between the inner cavity of the filter element and the outer wall of the support rod 411, and a limiting block 4113 is fixedly connected to the inner wall of the filter element. The limiting block 4113 slides inside the limiting groove 4111, and a connecting spring 4112 is fixedly connected between the end of the limiting block 4113 and the end of the inner cavity of the limiting groove 4111;

[0028] A connecting block 4132 is fixedly connected to the outer wall of the filter element. The connecting block 4132 slides inside the groove 413, and an elastic spring 4131 is fixedly connected between the end of the connecting block 4132 and the end of the inner cavity of the groove 413. The centrifugal force is generated by the filter mechanism 4 during rotation, and the connecting spring 4112 and the elastic spring 4131 pull the filter element to make it swing left and right.

[0029] In order to filter the water-based paint more fully and reduce the mixing of impurities, several filter elements include a first filter plate 4121, a second filter plate 4122 and a third filter plate 4123. The filter holes of the first filter plate 4121, the second filter plate 4122 and the third filter plate 4123 decrease from bottom to bottom. The decreasing filter holes can improve the filtering effect of the water-based paint.

[0030] In order to make the filtering structure rotate more conveniently, the filtering mechanism 4 also includes a top cover 40 mounted on the top of the operating barrel 3, and a driving motor 401 is installed at the center of the surface of the top cover 40. The output end of the driving motor 401 is fixedly connected to the end of the support rod 411. The support rod 411 is driven to rotate by starting the driving motor 401, thereby rotating the filtering mechanism 4.

[0031] Secondly, a feed pipe 402 for feeding is connected to the top of the top cover 40, and a discharge pipe for discharging is connected to the bottom of the operating barrel 3. Materials are fed in through the feed pipe 402 and discharged through the discharge pipe.

[0032] When the water-based paint filtering device of the utility model is used, the user puts the filtering mechanism 4 into the operating barrel 3, the top cover 40 is sleeved with the operating barrel 3, and the water-based paint is put into the operating barrel 3 through the feeding pipe 402, and then the driving motor 401 is started to rotate the support rod 411 to drive the mounting bracket 41 to rotate, and centrifugal force is generated during the rotation, so that the first filter plate 4121, the second filter plate 4122 and the third filter plate 4123 connected by a plurality of connecting springs 4112 and elastic springs 4131 are shaken, wherein the shaking directions of two adjacent filter elements are opposite, and they are shaken horizontally or vertically respectively; while the filtering mechanism 4 is rotating, the outer wall of the mounting bracket 41 is fitted with the inner wall of the operating barrel 3, and the water-based paint that may be adhered to the inner wall of the operating barrel 3 can be scraped off, which is convenient for the subsequent cleaning of the inside of the operating barrel 3, and the water-based paint is filtered by a plurality of filter elements and finally discharged through the discharge pipe, and the user takes out the entire filtering mechanism 4, and the cleaning is quick and simple.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
