Comparison of advantages and disadvantages between new oil filter and traditional oil filter

1、 First, introduce the structure of the traditional plate frame oil filter:

The traditional plate and frame oil filter is composed of alternating filter plates and filter frames, which are supported on a pair of cross beams and can slide on them. They are pressed or pulled apart by the pressing device. The surface structure of the filter plate is convex and grooved

2、 Working principle of traditional plate and frame oil filter:

The filtrate is pumped into each filter chamber from the feed hole of the rear top plate through the pump, and the solid impurities in the filtrate are trapped in the filter chamber through the filter cloth, and the filter cake is gradually formed; The liquid is discharged out of the machine through the discharge hole on the plate frame. The discharge of plate and frame oil filter can be divided into two forms: open flow and hidden flow. The filtrate is directly discharged outside the machine through the discharge holes on both sides of the plate frame. The advantage of open flow is that it can observe the discharge of each filter plate and directly find problems through the transparency of the discharged filtrate; If the filtrate is discharged through the undercurrent holes of the plate frame and the rear top plate, the form is called undercurrent. The disadvantages of the traditional plate frame oil filter are intermittent operation, high labor intensity, requiring two workers to operate, and low production efficiency.

3、 Introduction to the structure of a new type of automatic slag discharge oil filter

The new automatic slag discharge oil filter is developed by Xinxiang Gaofu Screening Machinery Co., Ltd. according to the common problems in solid-liquid separation and filtration in various industries and the introduction of international advanced technology in the industry. It is composed of tank body, lifting mechanism, vibrator, filter leaf, butterfly valve assembly, pressure indicator, etc. the filter leaf adopts special stainless steel filter, which has long service life, large output and high accuracy; The original oil pressing mechanism, with low oil content in the slag and pneumatic butterfly valve, is more easy to operate and discharge the slag. It is suitable for the filtration and separation process of discolored oil, clarification filtration and crystal in the production of oil, chemical industry, medicine and other industries, especially to solve the problems of cotton seed, vegetable seed, castor oil and other machine-made crude oil in the oil industry, such as difficult to filter and difficult to discharge the slag.

4、 Introduction to the working principle of the new automatic slag removal oil filter:

After the filtrate is pumped into the tank and filled, the solid impurities in the filtrate are intercepted by the stainless steel filter screen under the action of pressure, and a filter cake is formed on the filter screen. The filtrate enters the liquid outlet pipe through the filter screen and flows out of the tank to obtain clear filtrate.

With the increase of filtration time, more and more solid impurities are trapped on the filter screen, which increases the thickness of filter cake, the filtration resistance, and the pressure in the tank. When the pressure rises to a certain value, the slag needs to be discharged. Stop inputting the filtrate into the tank, and then blow the filter cake dry with steam. Close the steam, open the butterfly valve and start the vibrator to make the filter blade vibrate, and the filter cake on the filter screen will be vibrated and discharged through the slag discharge port under the tank.

5、 Features of the new automatic slag discharge oil filter:

1. Compact structure and small footprint;

2. Good filtering effect, high precision and low loss;

3. Vibration slag removal, avoiding manual slag removal, convenient operation and low labor intensity;

4. Stainless steel screen is used to avoid the disadvantage of replacing filter cloth or paper, reduce cost and improve production efficiency. Two parallel machines can realize continuous production.

5. Fully enclosed operation, environmental protection, low material consumption.

6： Application scope of the new automatic slag discharge oil filter:

Petrochemical Industry: diesel oil, lubricating oil, white oil, transformer oil, etc

Oil: peanut oil, soybean oil, rapeseed oil, sunflower oil, etc

Food: salad oil, starch, sugar juice, monosodium glutamate, milk, vinegar, etc

Pharmaceutical: hydrogen peroxide, vitamin C, glycerin, etc

Coatings: varnish, resin paint, dye, 685 varnish, etc

Organic chemical industry: various organic acids, methanol, ethanol, esters, benzene, aldehydes, etc

By comparing the above aspects of the two, the new automatic slag removal oil filter has more advantages than the traditional plate and frame type oil filter, and is the preferred equipment in the filtration industry.
