[0002] Negative pressure filter is a device that uses vacuum negative pressure as a driving force to achieve solid-liquid separation. Under the action of vacuum negative pressure (0.04-0.07MPa), the liquid in the suspension is pumped away through the filter medium (filter cloth), while the solid particles are retained by the medium, thus achieving the separation of liquid and solid.

[0003] In terms of structure, the filter sections are arranged along the horizontal length direction, and can continuously complete the operations of filtering, washing, drying, filter cloth regeneration, etc. The rubber belt filter has the advantages of high filtering efficiency, large production capacity, good washing effect, low filter cake moisture, flexible operation, and low maintenance cost. The rubber belt filter can be widely used in solid-liquid separation in the fields of metallurgy, mining, chemical industry, papermaking, food, pharmaceuticals, environmental protection, etc.

[0004] At present, when a negative pressure filter is used for cutting fluid, the filtrate after filtering by the negative pressure filter will be collected through a clean liquid tank, but a large amount of bacteria and viruses will be produced in the filtrate, which will in turn produce odor, etc., and further improvements to the negative pressure filter are needed.

[0031] Reference Figure 1 In this embodiment, a sterilization mechanism of a cutting fluid negative pressure filter is installed in the negative pressure filter to collect the filtrate. Figure 1 As shown, the negative pressure filter includes a filter membrane transfer mechanism 1, a negative pressure filter mechanism 2, a dirty liquid storage box 3 and a filter storage box 4. The filter membrane transfer mechanism 1 passes through the negative pressure filter mechanism 2 to replace the filter membrane therein. The dirty liquid storage box 3 is located above the negative pressure filter mechanism 2, and the filter storage box 4 is located below the negative pressure filter mechanism 2. The clean liquid tank 5 is installed on one side of the dirty liquid storage box 3 and is connected to the filter storage box 4 through a pipeline. The dirty liquid in the negative pressure filter is first stored in the dirty liquid storage box 3, filtered by the negative pressure filter mechanism 2, and when the obtained filtrate is collected in the filter storage box 4, it is transferred to the clean liquid tank 5 through a pipeline.

[0032] Among them, refer to Figure 2 The sterilization mechanism of the cutting fluid negative pressure filter includes a clean liquid tank 5 and a clean liquid device disposed on the clean liquid tank 5, and the clean liquid device includes a purification component 52 and an oil removal component 53. Since the filtrate filtered by the negative pressure filter will be collected through the clean liquid tank 5, a large amount of bacteria and viruses will be generated in the filtrate, thereby generating odor, etc. In this embodiment, the clean liquid tank 5 is disinfected and sterilized by using the purification component 52 and the oil removal component 53.

[0033] Among them, the purification component 52 includes a fixing plate 521 and a purification lamp 522 arranged on the fixing plate 521.

[0034] Specifically, the purification lamp 522 is an ultraviolet lamp. Ultraviolet sterilization uses ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA or RNA in microbial cells, causing growth cell death or regenerative cell death, thereby achieving the effect of sterilization.

[0035] In terms of the structural installation of the purification lamp 522, the purification lamp 522 is evenly spaced and arranged on the fixing plate 521. The installation portion of the purification lamp 522 passes through the fixing plate 521 and is located above the fixing plate 521. In addition, a switch 523 for turning the purification lamp 522 on or off is provided on the installation portion, which helps to control the turning on or off of the purification lamp 522.

[0036] On the other hand, the present application also discloses an oil removal assembly 53 installed in the clean liquid tank 5, wherein the oil removal assembly 53 includes an oil removal disc 531 and a sealing cover 532 arranged on the clean liquid tank 5, and a connecting hole 5321 for the oil removal disc 531 to pass through is opened on the sealing cover 532, the lower half of the oil removal disc 531 is penetrated by the connecting hole 5321 to extend into the clean liquid tank 5 and contact the liquid surface, and the upper half of the oil removal disc 531 is penetrated by the connecting hole 5321 to extend out of the clean liquid tank 5, and the rotation direction of the oil removal disc 531 is perpendicular to the plane of the sealing cover 532. When the oil removal disc 531 rotates, the upper half of the oil removal disc 531 and the lower half of the oil removal disc 531 are continuously alternated. Then, the oil in the clean liquid tank 5 is taken out of the clean liquid tank 5 by the rotation of the oil removal disc 531, reducing the chance of bacterial and viral breeding.

[0037] Specifically, the axis of the de-oiling plate 531 is connected to a motor 5311, and the motor 5311 is installed on the sealing cover 532, thereby realizing the automatic rotation of the de-oiling plate 531. In addition, two scraping blades 5322 are provided on the sealing cover 532, and one end of each scraping blade 5322 is tightly against the upper half of the de-oiling plate 531, and the other end of the scraping blade 5322 is fixed on the sealing cover 532. When the de-oiling plate 531 rotates, the scraping blade 5322 scrapes off the oil stains adhered to the de-oiling plate 531, thereby improving the efficiency of the de-oiling plate 531 in removing oil stains in the clean liquid tank 5, thereby improving the clean liquid effect of the clean liquid tank 5, and reducing the chance of bacterial and viral breeding.
