[0005] Preferably, the filter bladder comprises a ring cover and a cup-shaped filter screen, the cup mouth of the filter screen is connected to the ring cover, and the ring cover is connected to the lower flow port of the pipe rack.

[0006] Preferably, a bracket is installed on the ring cover, and a spiral is rotatably installed between the bracket and the cup bottom of the filter screen.

[0007] Preferably, the rotation axis of the spiral body coincides with the pipeline axis of the pipe rack.

[0008] Preferably, the pipe rack is provided with a socket, the ring cover is provided with a clamping strip installed corresponding to the socket, and the ring cover is fixed to the pipe rack at a position away from the socket by screws.

[0009] Preferably, the pipe rack and the discharge pipe are fixed by a clamp.

[0010] Compared with the prior art, the filter device for a paint storage tank proposed in the utility model adopts the above technical solution and achieves the following technical effects:

[0011] In the utility model, the discharge pipe of the storage tank can filter solids when discharging materials and store the solids between the filter screen and the pipe rack. When discharging liquid, the tank body can flush the solids to dissolve the solids in the liquid. At the same time, when filtering the solids, it can avoid blocking the pipeline and keep the pipeline unobstructed. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
