[0018] In order to make the technical problems, technical solutions and advantages of the present application more clear, the following will be described in detail with reference to the drawings and specific embodiments.
[0019] As Figs. 1-3As shown, the embodiment of the utility model provides a pipeline filter for viscous material, including filter shell 103, filter core support and filter core. Wherein the both ends of filter shell 103 are feed inlet and discharge outlet respectively, is provided with feed flange 101 on feed inlet, is provided with discharge flange 102 on discharge outlet, multiple application can be connected by feed flange 101 and discharge flange 102 and realize head-to-tail connection. The aforementioned filter core support includes filter core outer cylinder 112, the side of filter core outer cylinder 112 is provided with hole, one end of filter core outer cylinder 112 is open end, is provided with support flange 111 in open end, the other end of filter core outer cylinder 112 is closed end, when needing to assemble filter core support in filter shell 103, closed end is inserted into filter shell 103 from feed inlet, and bolt is used between support flange 111 and feed flange 101 and is connected. The aforementioned filter core includes filter core framework 132 and filter screen 133, filter core framework 132 includes two oppositely arranged rings, is provided with support bone between two rings, and the support bone is fixed on the circumferential direction of two rings, and both ends are fixedly connected with ring, and the aforementioned filter screen 133 is arranged in the space formed by support ring, and the filter screen 133 is attached to the support bone, and the filter core is inserted into the filter core outer cylinder 112 from the open end.
[0020] Further, the framework pull rod 131 is arranged on the ring, and the framework pull rod 131 is arranged along the radial direction of the ring, and the both ends of the framework pull rod 131 are fixedly connected with the ring.
[0021] Preferably, the first sealing ring 142 is arranged between the support flange 111 and the ring.
[0022] Preferably, the second sealing ring 141 is arranged between the support flange 111 and the feed flange 101.
[0023] The filter shell gradually expands from the both ends of the filter shell 103 to the middle part of the filter shell 103.
[0024] When the viscous material enters from the feed inlet, the viscous material acts on the filter core framework 132 and the filter screen 133, and under the support of the filter core framework 132, the deformation of the filter screen 133 can be effectively avoided. Since the first sealing ring 142 is arranged between the ring and the support flange 111, a gap can be avoided between the ring and the support flange 111. The viscous material also acts on the filter core support, and the filter core support has a tendency to move downstream, and the second sealing ring 141 can avoid a gap between the support flange 111 and the feed flange 101. The filter core outer cylinder 112 protects the filter core framework 132, which can maintain the stability of the filter core in the case of temporary overpressure of the filter core, and can also prevent the filter core from deforming during long-term operation.
[0025] After filtering, the viscous material is extruded from the hole in the side of the filter core outer cylinder 112, the middle diameter of the filter housing 103 is larger than the diameter of the two ends to form a buffer cavity, which plays a role of capacity expansion to buffer the extruded viscous material, further ensuring the stability of the application.
[0026] When replacing the filter core, a large resistance is generated in the application, so a skeleton pull rod 131 is arranged on the ring, at this time, only the filter core skeleton 132 and the filter screen 133 need to be pulled out together, without pulling out the filter core outer cylinder 112, thereby facilitating the replacement of the filter core.
[0027] The above is the preferred embodiment of the application, it should be pointed out that for ordinary skilled in the art, without departing from the principles of the application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the application.
