[0024] The following will be combined with the drawings in the embodiments of 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.

[0025] Example:

[0026] See also Figure 1-Figure 3 The utility model provides a filtering device for producing fluorocarbon coatings, including a pump 1, a filter housing 2 is fixedly installed at the feed inlet end of the pump 1, the top of the filter housing 2 is integrally connected to a lining shell 3, the lining shell 3 is provided with a material passing opening 4 around an axis, a material passing through hole 5 is provided at the bottom of the lining shell 3, a filter bag 6 is placed inside the lining shell 3, a hollow counterweight hollow ball 7 is placed below the filter bag 6 in the lining shell 3, and a clamping cover 8 is threadedly installed on the top of the lining shell 3.

[0027] Specifically, Figure 1As shown, an internal threaded opening is provided at the top of the filter housing 2, and the internal threaded opening is threadedly connected to the clamping cover 8. A spacing is left between the internal threaded opening and the opening of the liner shell 3. A ring piece is provided at the opening of the filter bag 6, and the ring piece is placed at the position of the spacing. The clamping cover 8 is pressed on the ring piece to facilitate the fixation of the filter bag 6. The sealing structure is a fixed structure, which simplifies the device design.

[0028] Specifically, the diameter of the hollow counterweight hollow ball 7 is larger than the diameter of the material passing hole 5 and smaller than the width of the material passing opening 4, so as to prevent the hollow counterweight hollow ball 7 from detaching from the liner shell 3.

[0029] Specifically, Figure 1 As shown, the bottom of the liner shell 3 is in an arc shape, which facilitates the hollow counterweight hollow ball 7 to automatically reset to the bottom center position of the filter bag 6.

[0030] Working principle:

[0031] Connect the paint input pipe at the position of the compression cover 8, start the pump 1, and the paint enters the filter bag 6 from the compression cover 8. The paint filtered by the filter bag 6 comes out from the material passing port 4 and the material passing hole 5 of the liner shell 3 and is discharged by the pump 1.

[0032] Replace the filter bag 6, separate the compression cover 8 and the pipe connected to the pump 1, remove the compression cover 8, invert the filter housing 2, and the hollow counterweight hollow ball 7 presses the filter bag 6 and falls rapidly to press the filter bag 6 out.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
