Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device that is easy to assemble and disassemble. Background Technology

[0002] In the PDCPD product processing flow, the Y-shaped filter is responsible for filtering the raw materials and preventing impurities from entering subsequent processes;

[0003] Existing Y-type filters lack an effective residue cleaning mechanism. After each material filtration, a large amount of residue remains in the filter valve body. Due to the active chemical properties of PDCPD raw materials, prolonged residue can easily lead to quality changes, resulting not only in material waste but also potential clogging of the filter, reducing equipment lifespan and increasing maintenance costs. Furthermore, traditional Y-type filters are extremely inconvenient to disassemble and assemble filter components. When it is necessary to replace the filter screen or clean and maintain the internal parts, operators often need to use a variety of complex tools, consuming a lot of time and effort to complete the disassembly. This greatly reduces production efficiency and cannot meet the needs of modern high-efficiency production. Utility Model Content

[0004] The purpose of this invention is to provide a filter device that is easy to assemble and disassemble, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A filter device that is easy to assemble and disassemble includes a vertical valve body, with fixed flanges fixedly installed at both ends of the vertical valve body. A filter valve body is fixedly installed on the outside of the vertical valve body. A fixed seat is fixedly installed at the end of the filter valve body away from the vertical valve body. A connecting seat is fixedly installed at the end of the fixed seat opposite to the filter valve body through a connecting cap. An insert is fixedly installed on the connecting seat. A filter tube is fixedly installed on the insert and the insert communicates with the filter tube channel. A mechanical seal is fixedly installed inside the connecting seat. A rotating shaft is rotatably installed inside the mechanical seal. A material lifting plug is also inserted inside the insert.

[0007] As a further preferred embodiment of this utility model, a positioning ring is fixedly installed on the inner side of the vertical valve body, and the positioning ring is obliquely placed in the vertical valve body. The positioning ring can be used to position the insertion tube and filter tube into the filter valve body, and the positioning ring can also close the gap between the insertion tube and the inner wall of the vertical valve body.

[0008] As a further preferred embodiment of this utility model, a limiting groove is provided at the end of the connecting seat opposite to the insertion tube, and the fixing ring on the inner side of the connecting cap is inserted into the limiting groove. The connecting cap located above the connecting seat is also threaded to the outer side of the fixing seat. By installing the connecting seat at the lower end of the fixing seat through the connecting cap, the connecting seat, insertion tube, and filter tube can be quickly disassembled and assembled.

[0009] As a further preferred embodiment of this utility model, multiple guide rails are fixedly installed on the inner side of the insertion tube and the filter tube.

[0010] As a further preferred embodiment of this utility model, one end of the rotating shaft extends through the mechanical seal to the lower part of the connecting seat, and the other end extends through the mechanical seal into the insertion tube and filter tube, and a spiral pattern is provided on the outer side of the rotating shaft located in the insertion tube and filter tube.

[0011] As a further preferred embodiment of this utility model, the lifting plug has a conical structure, with multiple sliding grooves on the outer side and a screw hole in the middle of the inner part of the lifting plug. The sliding grooves are slidably connected to the corresponding guide rails, and the screw hole is threadedly connected to the rotating shaft. By sliding the lifting plug to the corresponding guide rails through the multiple sliding grooves on the outer side, the axial movement of the lifting plug can be limited, so that when the rotating shaft rotates in the screw hole, the lifting plug can push the raw material in the filter valve body into the vertical valve body.

[0012] As a further preferred embodiment of this utility model, a base is fixedly installed at the lower end of the connecting seat, and a motor is fixedly installed at the lower end of the base. The motor is electrically connected to an external main controller through a connecting cable, and the output end of the motor is fixedly connected to one end of the rotating shaft through a coupling.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the raw material flowing through the vertical valve body can be filtered by installing the insert tube and filter tube in the filter valve body through the connecting seat. After a single raw material filtration is completed, the rotating shaft can be driven by the motor to rotate, so that the rotating shaft rotates in the screw hole in the lifting plug. The lifting plug can push the raw material remaining in the filter valve body back into the vertical valve body to flow out, avoiding the raw material from remaining in the filter valve body for too long and undergoing quality changes. With the help of the connecting cap, the connecting seat, insert tube and filter tube can be quickly disassembled and assembled in the filter valve body, improving the convenience of operation.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, the present invention provides a filter device that is easy to assemble and disassemble, including a vertical valve body 1, with fixed flanges 2 fixedly installed at both ends of the vertical valve body 1, a filter valve body 3 fixedly installed on the outside of the vertical valve body 1, a fixed seat 4 fixedly installed at the end of the filter valve body 3 away from the vertical valve body 1, a connecting seat 5 fixedly installed at the end of the fixed seat 4 opposite to the filter valve body 3 through a connecting cap 6, an insert tube 7 fixedly installed on the connecting seat 5, a filter tube 8 fixedly installed on the insert tube 7, and the insert tube 7 and the filter tube 8 are connected by a channel, a mechanical seal 9 fixedly installed inside the connecting seat 5, a rotating shaft 10 rotatably installed inside the mechanical seal 9, and a material lifting plug 16 inserted inside the insert tube 7.

[0023] like Figure 2 As shown, a positioning ring 13 is fixedly installed on the inner side of the vertical valve body 1, and the positioning ring 13 is obliquely placed inside the vertical valve body 1. The positioning ring 13 can be used to position the insertion tube 7 and the filter tube 8 into the filter valve body 3, and the positioning ring 13 can also close the gap between the insertion tube 7 and the inner wall of the vertical valve body 1.

[0024] like Figures 2-5As shown, a limiting groove 14 is provided at the end of the connecting seat 5 opposite to the insertion tube 7, and the fixing ring on the inner side of the connecting cap 6 is inserted into the limiting groove 14. The connecting cap 6 located above the connecting seat 5 is also threaded to the outer side of the fixing seat 4. By installing the connecting seat 5 at the lower end of the fixing seat 4 through the connecting cap 6, the connecting seat 5, insertion tube 7, and filter tube 8 can be quickly disassembled and assembled. Multiple guide rails 15 are fixedly installed on the inner side of the insertion tube 7 and the filter tube 8. One end of the rotating shaft 10 extends through the mechanical seal 9 to the lower part of the connecting seat 5, and the other end extends through the mechanical seal 9 into the insertion tube 7 and the filter tube 8. A spiral 19 is provided on the outer side of the rotating shaft 10 located in the insertion tube 7 and the filter tube 8. The lifting plug 16 has a conical structure, and the outer side of the lifting plug 16... Multiple sliding grooves 17 are provided, and a screw hole 18 is provided in the middle of the lifting plug 16. The sliding grooves 17 are slidably connected to the corresponding guide rails 15, and the screw hole 18 is threadedly connected to the rotating shaft 10. The lifting plug 16 can be slidably connected to the corresponding guide rails 15 through the multiple sliding grooves 17 on the outside to limit the axial movement of the lifting plug 16. Thus, when the rotating shaft 10 rotates in the screw hole 18, the lifting plug 16 can push the raw material in the filter valve body 3 into the vertical valve body 1. The lower end of the connecting seat 5 is fixedly installed with a base 11, and the lower end of the base 11 is fixedly installed with a motor 12. The motor 12 is electrically connected to the external main controller through a connecting cable, and the output end of the motor 12 is fixedly connected to one end of the rotating shaft 10 through a coupling.

[0025] It should be noted that this utility model is a filter device that is easy to assemble and disassemble. When the raw material passes through the vertical valve body 1, the raw material entering the vertical valve body 1 for the first time will impact the filter valve body 3. Thus, the filter tube 8 in the filter valve body 3 filters the raw material flowing through the vertical valve body 1, thereby intercepting and filtering impurities and raw material particles in the insertion tube 7 and filter tube 8. However, after a single batch of raw material passes through the vertical valve body 1, due to the inclined setting of the filter valve body 3, some raw material will remain in the filter valve body 3 and cannot be discharged in time. At this time, the motor 12 can be started by setting a program through an external main controller, and the output end of the motor 12 will drive the rotating shaft 10 to rotate. A certain process is initiated, causing the threaded portion of the rotating shaft 10 to rotate within the threaded hole 18 of the lifting plug 16. This allows the lifting plug 16, in conjunction with the outer sliding groove 17 and the guide rail 15 inside the insertion tube 7 and filter tube 8, to move in the direction perpendicular to the valve body 1. This allows the lifting plug 16 to push the material remaining in the filter valve body 3 into the filter tube 8 located in the vertical valve body 1, thus pushing the material remaining in the filter valve body 3 back into the vertical valve body 1 for discharge. Then, the motor 12 rotates in the reverse direction, causing the output end of the motor 12 to drive the rotating shaft 10 to rotate in the reverse direction within the threaded hole 18, thereby resetting the lifting plug 16.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
