Description

Quick-install quick-release filter

technical field

The utility model relates to a filter for conveying oil, in particular to a quick-installation and quick-disassembly filter.

Background technique

The filter is a very important oil equipment in the oil depot. It is used to remove impurities in the oil. It is necessary to open the cover frequently to clean the dirt filter. At present, the pump room of the oil depot uses a filter with the function of filtering oil in front of the pump. The top cover of this traditional filter is equipped with a peeper in front of the pump to check whether the vacuum system of the pump room is working normally. This structure makes it very difficult to clean the filter, and most of the peeper pipelines installed in the pump room of the oil depot are connected by threads, and the threads of the connecting parts are filled with sealing oil to seal, and the sealing effect is not good , often in the process of transporting oil, due to the operation and vibration of the oil pump, leakage occurs at the joints of the threads. At the same time, the traditional filter cylinder and the gland are all bolted, and it is very inconvenient to remove and install the cover every time it is cleaned. If the cleaning of the filter is carried out, the peeper must be removed at first, and then the bolts of the filter top cover can be removed with tools and a certain strength before cleaning. In short, the traditional filter is difficult to install and disassemble, difficult to clean, poor sealing effect, and may cause damage to the gaskets of various joints during the operation process.

The operation is simple, and it is convenient to clean the dirt and filter screen in the filter, thereby improving work efficiency, reducing the labor intensity of operators, and reducing The cost of cleaning operations also ensures that the filter is cleaned on time and the quality of the oil is guaranteed;

2. The sealing device adopts an inward-facing V-shaped sealing ring, which has good and reliable sealing performance, and both positive and negative pressure seals can be guaranteed;

3. At the outlet of the short oil inlet pipe of the filter, there is a deflector leading to the bottom of the filter, which can change the flow direction of the liquid, reduce the generation of static electricity and prevent the filter from breaking through.

4. A telescopic bracket is installed at the bottom of the short oil inlet and outlet pipes to reduce the damage to the cleaning workers during operation and improve the aesthetics.

5. The sewage pipeline at the bottom of the filter is bent into a 90° elbow, and a joint for installing a short rubber sewage pipe is installed at the outlet.

Detailed ways

As shown in Figures 1 and 2, the quick-installation and quick-release filter includes a cylinder body 5, which is characterized in that: the upper end of the cylinder body 5 is provided with a flange 4 with a toothed inner edge, which is pressed The cover 1 is installed on the flange 4, a sealing ring 3 is provided between the gland 1 and the flange 4, an ear plate 4-1 is provided on one side of the flange 4, and one end of the pressure rod 2 passes through the ear plate 4-1 and the flange The flange 4 is connected, the other end of the pressure rod 2 is provided with a ball handle 2-1, the pressure rod 2 is provided with a pressing device, the left and right sides of the cylinder 5 are respectively provided with an oil inlet pipe 8 and an oil outlet pipe 9, and the cylinder 5 There is a filter screen compartment 10 inside, a filter screen 7 is provided on the filter screen compartment, a deflector 6 is provided at the oil inlet pipe 8 of the cylinder body 5, a sewage discharge pipe 11 is provided at the bottom of the cylinder body 5, and a peeper 12 is located in the cylinder body. side of body 5.

The outer shape of the gland 1 is a gear shape. The sealing ring 3 is an inward V-shaped sealing ring. The lower part of the ball handle 2-1 on the compression bar 2 is provided with a bolt 2-2, and the compression bar 2 is connected with the flange 4 through the bolt 2-2. The pressing device includes a disc spring 13 , which is arranged in the disc spring sleeve 14 through a pressing block 19 and a pressing plate 15 , and the pressing device is connected to the pressing bar 2 through a leakage-proof bolt 16 . The sewage pipe 1 is provided with a 90° elbow structure, the sewage pipe 11 is provided with a valve 17 , and the outlet of the sewage pipe 11 is provided with a rubber hose joint 18 . The guide direction of the deflector 6 is set to lead to the bottom of the cylinder 5 .

The sealing device adopts an inward V-shaped sealing ring, which is used on the top cover of the filter, so that the filter can withstand large positive and negative pressures. During positive pressure, when there is pressure in the filter, part A of the sealing ring expands outward. The greater the pressure, the tighter the A part of the sealing ring fits the upper and lower planes, and the better the sealing effect, so that the sealing is guaranteed and more reliable under positive pressure. Under negative pressure, that is, when the pump pumps oil, negative pressure will be generated in the filter. At this time, the pressure rod on the filter will make part A of the sealing ring press the upper and lower planes, thereby achieving a negative pressure sealing effect.

The oil passes through the oil inlet, and the flow direction of the liquid is changed through the deflector, so that the oil passes to the bottom of the filter. The oil passes through the filter to eliminate impurities and flows out through the oil outlet. The filtered impurities are discharged from the sewage pipe. The peeper at the axis of the side of the filter is used to check whether the vacuum system of the pump room is working properly.

When performing cleaning operations, the ball handle and pin shaft are removed, the pressing rod and pressing plate can be removed, and then the pressing cover is pressed down and rotated to complete the disassembly, and the filter screen can be easily taken out for cleaning.
