Description

High-pressure continuous production waste oil filter device with automatic slag scraping and slag discharge

technical field

The utility model belongs to a waste oil filter device for high-pressure continuous production, which is a production device for physically purifying waste oil, in particular to a waste oil filter device for high-pressure continuous production with automatic scraping and slag discharge.

Background technique

Because waste oil contains a lot of dregs, natural sedimentation and centrifugal separation are often used for filtration, but for dregs with a density close to the density of waste oil, filter screens and filter cloth filters can only be used to filter, because the filtration pressure is limited to Within 0.6MPa, there are also certain shortcomings;

1. After a certain period of work, the meshes of the filter screen and filter cloth are clogged, and the filter cloth of the filter screen must be cleaned of dregs, and the filter machine needs to be disassembled to replace the filter cloth, which directly affects the normal production.

2. Cleaning the filter screen and filter cloth is time-consuming and laborious, and it is easy to cause damage to the filter screen and filter cloth;

3. Because the filtration pressure is limited within 0.6MPa, the filtration effect cannot be achieved for waste oil with high viscosity.

Utility model content

The purpose of the utility model is to provide a waste oil filter device for continuous high-pressure continuous production and automatic slag scraping and discharge. The dross on the Internet can be automatically removed, and it can be automatically and continuously produced, which can greatly improve production efficiency.

The purpose of this utility model is achieved in this way: a high-pressure continuous production of waste oil filtering device for automatic slag scraping and slag discharge, an inner tank with evenly distributed through holes is arranged in the vertical tank body, and the opening of the lower part of the inner tank is connected with the The bottom surface of the tank body is connected, and a filter screen is set on the outer wall of the inner tank, which divides the tank body into an oil inlet chamber and a filter chamber. An oil inlet pipe is arranged on the bottom surface of the oil inlet chamber of the tank body, and an An oil outlet pipe is set on the bottom surface of the tank body, and a vertical shaft driven by a motor, a reducer and a ratchet mechanism is set on the upper end of the tank body. The lower part of the tank is connected to the scraper frame through evenly distributed swing hinges, and a spring-controlled scraper is installed on the scraper frame. The top of the tank and the oil outlet pipe are respectively installed with pre-filtration and post-filtration pressure gauges.

The principle of this utility model is: when the equipment starts to work, the oil to be filtered is transported through the pump pressurization, and enters between the inner tank and the outer cylinder of the device at a certain pressure (≤3.0MPa) from the oil inlet pipe, and the oil to be filtered is passed through The small holes on the filter net, the bottom net and the liner enter the interior of the liner and flow out through the oil outlet pipe to achieve filtration. At the beginning, due to the very good permeability of the filter, the pressure difference between the inner tank and the outer tank was not very large. After a period of operation, a certain amount of dregs adhered to the surface of the filter, which reduced the passing capacity of the filter. , so that the pressure difference between the inside of the inner tank and the outside of the inner tank increases. When the pressure difference increases to 1.0MPa, it means that the filter screen has a poor passing capacity. The motor is energized and the transmission starts to work. Slowly drive the scraper frame on the rotating half-tank to work, and the rotating scraper cuts into the surface of the filter screen at a certain angle and pressure under the action of the compression spring and torsion spring, and scrapes the dross that clings to the surface of the filter screen and blocks the mesh. and the dross enters the round cavity of the scraper holder tube, preventing the scraped dross from being mixed into the oil to be filtered. Under the action of gravity, it gradually settles to the bottom of the device, and is scraped into the slag collection pool by the slag scraper. Because the rotation direction of the scraper is along the direction of the filter mesh, the filter mesh is also rolled tighter and tighter under the scraping of the scraper. , which is more conducive to the scraper to scrape off the dregs attached to the filter screen. In order to ensure the correct rotation direction, an anti-reverse ratchet mechanism is installed in the transmission assembly to prevent the reverse rotation of the scraper from causing damage and falling off of the filter screen. At the same time, under the balance of the swing hinge, the scraper does not tilt due to uneven force, but always maintains the overall contact between the scraper blade and the filter screen; after a period of cleaning, as the passing capacity of the filter screen gradually increases, When the pressure of the electric contact pressure gauge before filtering drops to 0.5MPa, the electric contact pressure gauge cuts off the power supply of the working motor, and the transmission device stops rotating. During the rotary cleaning process of the scraper, the dross first enters the dregs collection pool under the cleaning of the scraper. After the scraper frame rotates for 30 minutes, the timer sends an instruction, the upper slag discharge electric valve is opened first, and under the action of pressure, the slag flows into the transitional slag storage pool through the upper electric valve, and after 20 minutes, the upper slag discharge electric valve is closed , and then open the lower slag discharge electric valve to discharge the slag. Then the lower slag discharge electric valve is closed. Such repeated automatic removal of dregs and discharge enables the device to continuously filter waste oil.

The utility model has reasonable structure and reliable performance, realizes high-quality filtration of waste oil conveyed under high pressure, can not only automatically remove dregs on the filter net, automatically remove dregs, but also automatically and continuously produce, greatly improving production efficiency.
