Description

Technical Field

[0001] This utility model belongs to the technical field of chip conveyor filtration equipment, and more specifically, it relates to a cylindrical filter suitable for chip conveyors. Background Technology

[0002] Currently, in industries such as machining, chip conveyors are essential equipment for cleaning the mixture of chips and coolant generated during processing. Existing chip conveyors are typically equipped with filter cartridges to filter the coolant, ensuring its recycling.

[0003] However, existing chip conveyor filter cartridges have some obvious shortcomings. Most current filter cartridges use filter cloth as the filter medium. After a period of use, the filter cloth will be clogged by impurities and needs to be replaced. However, the process of replacing the filter cloth is very cumbersome. It not only requires machine shutdown and consumes a lot of time and manpower, but also may result in improper operation during the replacement process, which may lead to the new filter cloth not being installed tightly, affecting the filtration effect. In addition, frequent replacement of filter cloth also increases the operating cost. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a cylindrical filter suitable for chip conveyors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical filter suitable for a chip conveyor, comprising a filter cylinder body, a cover plate installed on the top of the filter cylinder body, a handle provided on the top of the cover plate, and an air inlet valve installed on the cover plate to allow air to enter the filter cylinder body to blow away chips. A pressure switch is installed on one side of the filter cylinder body to detect the internal pressure. A positioning frame is welded inside the filter cylinder body, dividing the interior of the filter cylinder body into an upper filter chamber and a lower filter chamber. A liquid outlet is connected to one side of the upper filter chamber. The cutting fluid is filtered and discharged. Symmetrical limiting blocks are provided on the inner wall of the upper filter chamber. A clamping assembly is provided below the limiting blocks. A positioning plate is clamped at the bottom of the clamping assembly. The positioning plate is provided with multiple positioning holes, through which the cutting fluid flows. A filter screen is provided at the bottom of the positioning plate and is engaged with the positioning frame. A drain port is provided at the bottom of the filter body, which is connected to the lower filter chamber. Impurities and cutting fluid are discharged into the chip conveyor module through the drain port. A liquid inlet is provided on one side of the lower filter chamber, through which the cutting fluid is supplied.

[0006] As an optional solution of this utility model, the top of the filter cylinder body is provided with an annular groove, and a sealing ring is installed inside the annular groove. The sealing ring is pressed by the cover plate to achieve waterproof sealing.

[0007] As an optional solution of this utility model, the clamping assembly includes an adjusting plate, a nut is provided on the adjusting plate, an adjusting screw is engaged with the internal thread of the nut, an adjusting handle is provided at the top of the adjusting screw, the adjusting handle is rotated for adjustment, and an adjusting block is provided at the bottom of the adjusting screw, the adjusting block is in contact with the positioning plate.

[0008] As an optional solution of this utility model, the filter cylinder is made of SUS304 material.

[0009] As an optional solution of this utility model, the inlet, drain, and outlet are all equipped with switching valves.

[0010] As an optional solution of this utility model, a flange base is welded to the bottom of the filter cartridge body.

[0011] This utility model provides a cylindrical filter suitable for chip conveyors, which has the following advantages:

[0012] The chip removal and filtration system is independently controlled by setting up an inlet, outlet, and drain port. The positioning plate is tightened by adjusting the screw to ensure stable operation of the stainless steel filter cylinder. The filter cylinder is blocked and an alarm is triggered by a pressure switch. Air is introduced through the air inlet valve to blow off iron filings and other debris adsorbed on the outside of the filter cylinder. Impurities and cutting fluid are discharged into the chip conveyor module through the drain port. No replacement or disassembly is required, which improves the filtration sealing performance.
