[0001] The utility model belongs to the technical field of wire enameled paint filtering equipment, and in particular relates to an environmentally friendly wire enameled paint filtering device. Background Art

[0002] Environmentally friendly wire enameling paint is very popular in the market because of its advantages such as good thermal stability and higher high temperature resistance, which meets the needs of the development of new application technologies for enameled wires.

[0003] At present, when using wire enameled paint, the paint purity is often insufficient, and it contains impurities such as soluble and insoluble particles remaining in the production process or generated in the later storage, which causes the adsorption capacity to decrease, resulting in the paint falling off, seriously affecting the product quality and normal use of the finished enameled wire. Therefore, it is necessary to filter the impurities of the wire enameled paint before painting.

[0004] However, the wire enamel itself is relatively viscous and has poor fluidity, which is not conducive to filtering work. At the same time, if the filter used for filtering is used for a long time, the impurities in the wire enamel will be deposited on the surface of the filter, affecting the smooth progress of subsequent filtration work. If it is frequently replaced and cleaned, it requires downtime, which will take up production time, affect production progress, and reduce production efficiency. In order to solve the above problems, it is necessary to develop an environmentally friendly wire enamel filtering device. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further specifically described below in conjunction with the accompanying drawings.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides an environmentally friendly enameled wire paint filtering device, comprising a filtering barrel 1, a feed port 2 arranged at the upper end of the filtering barrel 1, and a discharge port 11 arranged at the lower end of the filtering barrel 1.

[0022] The side wall of the filter barrel 1 is provided with a sandwich structure 7 for heating, and the sandwich structure 7 is filled with flowing constant temperature hot water. The constant temperature hot water is used to heat the wire enamel in the filter barrel 1. The heated wire enamel has good fluidity, fast filtration speed and high filtration efficiency. Heating can also dissolve the soluble particulate impurities contained therein and filter them out for use, thereby reducing waste of raw materials.

[0023] A fixed filter screen 9 having the same diameter as the inner diameter of the filter barrel 1 is provided at the lower part of the filter barrel 1, located above the discharge port 11; a stirring shaft 5 is provided at the center of the filter barrel 1, located above the fixed filter screen 9; a discharge pipe 10 extending vertically downward into the bottom of the fixed filter screen 9 is provided at the lower end of the stirring shaft 5; a plurality of stirring filters 6 that swing along with the stirring shaft 5 are evenly arranged around the stirring shaft 5; the stirring filter 6 can filter the wire paint while completing the stirring work, increase the filtering channel, and assist the fixed filter screen to further improve the filtering efficiency; the lower end of the stirring filter 6 is connected to the discharge pipe 10, and the wire paint filtered out of the stirring filter 6 falls from the discharge pipe 10 to the bottom of the stirring barrel 1, and then flows out from the discharge port 11.

[0024] The lower end of the stirring filter 6 is provided with a scraper 8 whose lower end abuts against the upper end of the fixed filter screen 9. The hanging plate 8 is used to remove impurities deposited on the upper end surface of the fixed filter screen 9 to prevent the impurities from clogging the filter screen over time and reducing the filtering effect.

[0025] Specifically, the stirring filter 6 includes two swinging filter screens 61 parallel to each other. During the swinging process, one of the two swinging filter screens 61 filters and the other removes impurities deposited on the surface. The two filter screens interchange their functions during the alternating swinging process to complete the designed function of the swinging filter 6. The inner ends of the two swinging filter screens 61 are fixedly connected to the stirring shaft 5 and the discharge pipe 10 arranged upper and lower. The upper, lower and outer end surfaces of the two swinging filter screens 61 are all closed by a closing plate 62.

The stirring filter 6 is connected to the discharge pipe 10 through the connecting port 101. The scraper 8 is provided on the closing plate 62 located at the lower end of the two swinging filter screens 61.

[0026] The outer end of the closing plate 62 located at the lower end of the two swinging filters 61 is higher than the inner end and is inclined to be provided with the scraper 8. After the outer end of the closing plate 62 is set higher than the inner end, it is beneficial for the enameled wire paint filtered by the swinging filter 61 to quickly flow into the discharge pipe 10, avoiding the filtered enameled wire paint to be retained and accumulated between the two swinging filters 61, affecting the filtering effect.

[0027] The lower ends of the two swing filter screens 61 are arranged against the upper end of the fixed filter screen 9 .

[0028] The cross section of the closing plate 62 is in a straight line, an arc or a V shape.

[0029] The stirring shaft 5 and the discharge pipe 10 are an integrated structure with the same outer diameter, which facilitates the installation of the stirring filter 6.

[0030] A gas pressurizing device 4 is provided at the upper end of the filter barrel 1 for pressurizing the inside of the filter barrel 1 to help speed up the filtering speed of the wire enamel in the filter barrel 1 .

[0031] A driving motor 3 is provided at the upper end of the filter barrel 1 for driving the stirring shaft 5 to swing around its central axis.

[0032] After completing the above installation, the utility model can be put into use. The wire varnish to be filtered is added into the filter barrel 1 from the feed port 2, circulating constant temperature hot water is introduced into the sandwich structure 7, the drive motor 3 is turned on, the stirring shaft 5 is driven to swing left and right in the horizontal direction at a preset angle, the gas pressurizing device 4 is turned on, the fixed filter screen 9 and the two swinging filter screens 61 are used to heat and pressurize the wire varnish, and the filtered wire varnish flows out from the discharge port 11.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
