In order to solve the technical problem, the utility model discloses a technical scheme is:

a pipeline filter comprises a feed inlet, a filter shell and a discharge outlet, wherein the filter shell is provided with the feed inlet and the discharge outlet which are communicated with an external pipe, the top of the filter shell is provided with a flange, two ends of the flange are fixed through quick-opening bolts, and the top of the flange is provided with a pressure gauge; the filter shell is characterized in that clamping grooves are formed in two sides of the middle of the inner wall of the filter shell, and a filter screen is clamped on the clamping grooves.

Preferably, the pipeline filter, wherein the inlet is arranged at one side of the upper end of the left side wall of the filter shell, and the outlet is arranged at the bottom of the filter shell.

Preferably, the pipeline filter, wherein the filter screen is a stainless steel filter screen with a pore size of 10-200 meshes.

Preferably, the pipeline filter, wherein the feed inlet, the discharge outlet and the external pipe are all connected through a connecting flange.

Preferably, the pipeline filter is provided with a handheld piece in the middle of the filter screen.

Preferably, the pipe filter, wherein the handle is in the shape of a bent pipe.

Has the advantages that:

the pipeline filter of the utility model has simple use method and convenient disassembly and installation, and can select filter discs with different filter mesh numbers according to the specific use requirements; by adding a simple clamping groove in the filter and then manufacturing and selecting different filter sheets, the pipeline filtering requirements of different product production can be met; by utilizing the blocking effect of the clamping groove and the pump pressure for liquid material flowing, a good sealing effect can be achieved.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, the utility model provides a pipeline filter, wherein, including feed inlet 1, filter housing 2 and discharge gate 3, filter housing 2 sets up feed inlet 1 and discharge gate 3 communicating with external pipe, the top of filter housing 2 is equipped with flange 4, flange 4 both ends are fixed through quick-opening bolt 5, the top of flange 4 is equipped with manometer 6; the filter shell 2 is characterized in that clamping grooves 7 are formed in two sides of the middle of the inner wall of the filter shell 2, and a filter screen 8 is clamped on the clamping grooves 7. By adding a simple clamping groove in the filter and then manufacturing and selecting different filter sheets, the pipeline filtering requirements of different product production can be met; the blocking effect of the clamping groove and the pump pressure for liquid material flowing are utilized, a good sealing effect can be achieved, and the processing cost of the circular filter disc is lower than that of the filter cylinder when the mesh number is high.

Specifically, wherein, feed inlet 1 sets up in the left side wall upper end one side of filter housing 2, discharge gate 3 set up in the bottom of filter housing 2.
