Description

Technical Field

[0001] The invention relates to the field of filtering devices, in particular to a white oil rapid filtering device. Background Art

[0002] White oil generally refers to mineral oil, which is a colorless and odorless mixture obtained from crude oil fractionation. It is widely used in the fields of chemistry, textile, chemical fiber, petrochemical, electricity, agriculture, etc., and is a basic raw material. In order to ensure the purity of white oil, it is necessary to remove impurities in the white oil stock solution through a filtering device. Patent application number: CN201820411793.X discloses a white oil filtering device, including white oil filtration, white oil filtration inlet, white oil filtration outlet, and white oil filter net. The white oil is filtered through the filter net, but this type of white oil rapid filtering device filters through the natural flow of white oil. Since white oil is relatively viscous, the flow speed of white oil is slow when passing through the filter hole, which affects the filtering efficiency of white oil.

[0003] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a white oil rapid filtering device.

[0005] The present invention can be implemented by the following technical solutions:

[0006] The invention discloses a white oil rapid filtering device, comprising a tank body fixed on a frame, a water inlet pipe fixed on the top of the tank body, a drain pipe fixed on the bottom of the tank body, a mounting plate fixed in the tank body, a liquid discharge port penetrating the mounting plate arranged on the mounting plate, a filter tube fixed above the liquid discharge port, filter holes evenly arranged on the filter tube, a piston slidably connected with the filter tube arranged in the filter tube, a push rod fixed on the top of the piston, a slide groove fixed on the push rod, a motor fixed on the tank body, a A turntable, a fixed column is fixed on the turntable, the end of the fixed column is arranged in a slide groove and is slidably connected to the slide groove, a scraper is also arranged in the tank body, the scraper is arranged around the filter tube, the scraper is fixed to the push rod, two fixed blocks are fixed on the mounting plate below the drain port, a rotating shaft rotatably connected to the fixed blocks is also arranged between the two fixed blocks, a baffle used in conjunction with the drain port is fixed on the rotating shaft, a torsion spring is also arranged on the rotating shaft, one end of the torsion spring is fixed to the fixed block, and the other end of the torsion spring is fixed to the baffle. The white oil to be filtered is discharged into the tank body through the water inlet pipe, the turntable is driven by the motor to rotate, and the fixed column on the turntable rotates with the turntable. When the fixed column rotates, the fixed column slides in the slide groove, and the fixed column drives the slide groove to move up and down, and the slide groove drives the push rod to move up and down, and the piston moves up and down with the push rod. When the push rod moves up, due to the action of the torsion spring, the baffle covers the discharge port to seal the bottom of the filter tube, and the piston moves upward. A negative pressure is formed in the filter tube below the piston. Through the traction of the negative pressure, the white oil outside the filter tube quickly enters the filter tube below the piston. When the piston moves downward, the pressure at the baffle position increases, the baffle rotates around the rotating shaft, and the baffle is separated from the discharge port. The white oil in the filter tube below the piston is discharged into the tank body below the mounting plate through the discharge port and discharged through the drain pipe. The device drives the piston up and down by the motor to achieve rapid filtration of the white oil through the filter tube, which greatly improves the filtration speed of the white oil. When the push rod moves up and down, the scraper moves up and down with the push rod, which can effectively prevent impurities from clogging the filter holes on the filter tube.

[0007] Preferably, the mounting plate is evenly provided with through holes penetrating the mounting plate.

[0008] Preferably, a sewage pipe is fixed on the tank body above the mounting plate. Impurities are collected in the tank body above the mounting plate and discharged through the sewage pipe for collection and treatment.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The device drives the piston to move up and down by a motor to quickly filter the white oil through the filter tube, which greatly improves the filtering speed of the white oil. When the push rod moves up and down, the scraper moves up and down with the push rod, which can effectively prevent impurities from clogging the filter holes on the filter tube.
