Description

Technical Field

[0001] The invention relates to the field of white oil storage equipment, and in particular to a liquid inlet mechanism of a white oil storage tank. Background Art

[0002] At present, the existing white oil storage tanks do not have a preliminary filtering function and cannot filter out large particles of impurities in the white oil. Therefore, there is a white oil storage tank with a patent number of CN217806480U. However, after the tank has filtered the incoming liquid for a long time, a large amount of impurities will accumulate on the filter net and affect the filtering efficiency and liquid circulation. Therefore, it is necessary to unscrew the screws on the flange of the adapter tube, remove the adapter tube, take out the filter net, clean the filter net, put it into the filter cartridge, and install the adapter tube. However, this method is cumbersome, and the installation and disassembly of the adapter tube is not convenient, which affects its scope of application and also makes it inconvenient to clean the filter net. Summary of the invention

[0003] The purpose of the present invention is to provide a liquid inlet mechanism for a white oil storage tank.

[0004] The technical problem of the present invention is mainly solved by the following technical solutions:

DETAILED DESCRIPTION

[0018] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0019] A liquid inlet mechanism for a white oil storage tank includes a filter cartridge 2 disposed on a liquid inlet of a storage tank 1, wherein a transfer tube 3 is disposed on the filter cartridge 2:

[0020] A funnel-shaped filter cover 4 is arranged in the filter cylinder 2, wherein the bottom end of the mouth of the filter cover 4 is connected to a cylinder 6 above the storage tank 1 through an inclined tube 5, a transparent observation window is arranged on the side wall of the cylinder 6, and the cylinder 6 is connected to the storage tank 1 through a reflux pipe 7, and a filter screen 8 is arranged in the cylinder 6, wherein the filter screen 8 is connected to a cover plate 10 on the top of the cylinder 6 through a vertical rod 9;

[0021] The transfer tube 3 is provided with a rotating shaft 11 extending into the filter cover 4, wherein a mounting rod 12 for fixing the rotating shaft 11 is provided on the inner wall of the transfer tube 3, and a rolling bearing for fixing the rotating shaft 11 is provided on the mounting rod 12, and a plurality of scraper rods 14 in contact with the inner wall of the filter cover 4 are fixed to the rotating shaft 11 via a cross bar 13, and a gear 15 is also provided at the top of the rotating shaft 11, wherein a rack 16 meshing with the gear 15 is provided on one side of the gear 15, and one end of the rack 16 passes through a through hole on the side wall of the transfer tube 3, and a protrusion is provided in the middle of the back side of the rack 16, wherein the protrusion is fixedly connected to the corresponding side wall of the transfer tube 3 via a telescopic rod.

[0022] In this embodiment, a flow sensor is arranged in the filter cartridge 2 below the filter cover 4 .

[0023] like Figure 2 As shown, a buckle plate 17 for sealing the through hole is disposed on the outer side of the transfer tube 3 , wherein a handle is disposed on the back side of the buckle plate 17 , and one end of the rack 16 is connected to the buckle plate 17 .

[0024] In this embodiment, the top end of the inclined tube 5 is connected to the filter cover 4, wherein a solenoid valve is provided on the inclined tube 5.

[0025] like Figure 1 , 2 As shown, the filter screen 8 is an arc-shaped concave structure, wherein the filter screen 8 is located below the inclined tube.

[0026] The method of using the present invention is as follows: injecting white oil into the storage tank 1 through the connecting pipe, the transfer pipe 3 and the filter cartridge 2 for storage, wherein the filter cover 4 filters the impurities in the white oil to prevent the impurities from entering the storage tank 1, and when the filter cover 4 is used for a certain period of time, the flow rate of the liquid flowing through the filter cartridge 2 is detected by the flow sensor. When the flow rate is too small, it indicates that a large amount of impurities are deposited in the filter cover 4. At this time, there is no need to disassemble the transfer pipe 3, and only the solenoid valve on the inclined pipe 5 needs to be opened, the bolts on the lower buckle plate 17 need to be removed, and then the rack 16 needs to be pulled to slide in the through hole. The rack 16 is driven to reciprocate left and right in the transfer tube 3, so that the gear 15 drives the rotating shaft 11 to rotate in the rolling bearing. At this time, the rotating shaft 11 drives the scraper rod 14 to rotate clockwise and counterclockwise on the inner wall of the filter cover 4 through the cross bar 13 to scrape off the impurities on the inside, so that the scraped impurities are mixed with a small amount of liquid and flow into the cylinder 6 through the inclined tube 5. In the above process, when the rack 16 reciprocates, it drives the telescopic rod to shrink and stretch through the convex block, and the telescopic rod prevents the rack 16 from being skewed when it moves left and right;

[0027] When the liquid mixed with impurities enters the cylinder 6, it is filtered by the filter screen 8, wherein the liquid enters the storage tank 1 through the reflux pipe 7 for recovery, and at the same time, the filter screen 8 is taken out of the cylinder 6 through the cover plate 10 and the vertical rod 9 to clean the impurities obtained by filtering, so that the impurities on the filter cover 4 can be cleaned without disassembling the transfer tube 3.

[0028] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
