Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a liquid carbon dioxide dust filter. Background Art

[0002] In the existing carbon dioxide purification process, the original gas filter plays a filtering role. It is a cap-shaped component made of fiber mesh with a filtration accuracy of 50um. When the gas enters the interior of the cap-shaped component, the dust impurities are intercepted and fall into the bottom of the filter cylinder and are discharged through the drain valve. The gas passes through the mesh and enters the next process from the filter outlet. The filter accumulates impurities after long-term use. It must be shut down and disassembled, and the filter mesh must be taken out to clean it, which affects production.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN209348307U discloses a filtering device, which achieves carbon dioxide filtering by setting a partition and a plain porcelain tube. The filter is easy to disassemble and assemble, has uniform filtering, and is easy to clean dust. The carbon dioxide filter described in the utility model includes a cylinder, a partition, and a plain porcelain tube. The cylinder includes an upper cylinder and a lower cylinder. The upper cylinder and the lower cylinder are fastened and sealed by fasteners. An air outlet is provided on the top of the upper cylinder, and an air inlet is provided on the lower part of the lower cylinder; a partition is provided between the upper cylinder and the lower cylinder to isolate the upper cylinder and the lower cylinder into two closed spaces, and a plurality of stepped holes are provided on the partition; the plain porcelain tube is adapted to the aperture and number of the stepped holes, the bottom end of the plain porcelain tube passes through the stepped holes, and the top end of the plain porcelain tube is fixedly connected to the partition.

[0005] However, the above patent still has problems that need to be improved in actual use. It is obvious that although the surface of the plain porcelain tube is smooth, after long-term use, a certain amount of dust will inevitably adhere to the surface of the plain porcelain tube, and cleaning of the dust is tedious and laborious.

[0006] To this end, we proposed a liquid carbon dioxide dust filter to solve the above disadvantages. Utility Model Content

[0015] 1. In the utility model, a cleaning brush is provided, and a driving motor drives the lifting plate to move downward, and the cleaning brush follows the movement, so that the dust on the outer wall of the plain porcelain tube can be scraped and cleaned, thereby reducing the risk of the plain porcelain tube being blocked by dust, ensuring the filtering effect and efficiency of the plain porcelain tube on dust, and saving time and effort during cleaning.

When in use, carbon dioxide containing impurities enters the cylinder 1 through the air inlet 2. Due to the isolation of the partition 5, the carbon dioxide can enter the upper part of the cylinder 1 only after being filtered by the plain porcelain tube 6, and is discharged from the air outlet 3 on the top of the upper cylinder 1 to complete the filtration. The plain porcelain tube 6 has high filtration accuracy and good filtration effect.

[0027] In this embodiment, the cleaning brush 15 is elastically fitted to the surface of the plain porcelain tube 6 .

[0028] Specifically, the elastic force of the spring 14 can push the cleaning brush 15 to always maintain a good elastic fit with the outer wall of the plain porcelain tube 6. It is not easy for a gap to form between the cleaning brush 15 and the plain porcelain tube 6, so that dust is not easy to remain on the outer wall of the plain porcelain tube 6, and the cleaning effect is more ideal.

[0029] In this embodiment, a plurality of through holes 13 are provided, and the plurality of through holes 13 are distributed on the surface of the lifting plate 12 in a rectangular array.

Due to the isolation of the partition 5, the carbon dioxide can enter the upper part of the cylinder 1 only after being filtered by the plain porcelain tube 6, and is discharged from the air outlet 3 on the top of the upper cylinder 1 to complete the filtration. The plain porcelain tube 6 has high filtration accuracy and good filtration effect. The driving motor 7 drives the lifting plate 12 to move downward, and the cleaning brush 15 follows the movement, which can scrape and clean the dust on the outer wall of the plain porcelain tube 6, reducing the risk of the plain porcelain tube 6 being blocked by dust, ensuring the filtering effect and efficiency of the plain porcelain tube 6 for dust, and saving time and effort during cleaning. Secondly, the elastic force of the spring 14 can push the cleaning brush 15 to always maintain a good elastic fit with the outer wall of the plain porcelain tube 6. It is not easy for the cleaning brush 15 to have a gap with the plain porcelain tube 6, so that it is not easy for dust to remain on the outer wall of the plain porcelain tube 6, and the cleaning effect is more ideal.

[0039] It should be noted that the model and specifications of the drive motor 7 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
