Description

Technical Field

[0001] This utility model relates to the field of oil storage tank technology, and in particular to an oil storage tank draining device. Background Technology

[0002] Oil storage tanks are containers used to store petroleum and its derivatives. They are widely used in the petroleum industry, chemical industry, and other fields that require the storage of liquid chemicals. Coal mines need to frequently take oil from oil storage tanks during the daily oil distribution process, so an oil tank draining device is required.

[0003] Because oil is stored in storage tanks, sediment or impurities may accumulate at the bottom of the tanks over a long period of time. These substances may be carried out when the oil is drained, affecting the quality of the oil and its subsequent use. Furthermore, the oil may release volatile organic compounds during the draining process, leading to air pollution and safety hazards. Therefore, there is an urgent need for an oil draining device for storage tanks to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an oil tank draining device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An oil storage tank discharge device includes an oil storage tank, a bottom plate at one end of the oil storage tank, an oil inlet tank fixed to the top of the bottom plate, a filter screen plate at the top of the inside of the oil inlet tank, a cleaning mechanism for cleaning the surface of the filter screen plate, a purification mechanism for purifying harmful gases released from the oil at the top of the oil inlet tank, and an oil outlet tank at the bottom of one end of the oil storage tank, with a control valve inside the oil outlet tank.

[0007] The cleaning mechanism includes grooves on both sides of the top inside the oil inlet tank. Sliding blocks are mounted inside each groove. A scraper is fixed to the side of each of the two sliding blocks that are close to each other, and the bottom of the scraper contacts the top of the filter screen. A through groove is provided on one side of the oil inlet tank, and a sealing block is provided inside the through groove. A U-shaped mounting bracket is fixed to the end of the sealing block away from the oil inlet tank. A fixing rod is fixed to the end of the U-shaped mounting bracket near the sliding block, and the other ends of the two fixing rods are fixedly connected to one end of the sliding block. Limiting mechanisms are provided on both sides of the oil inlet tank to limit the movement of the U-shaped mounting bracket. The U-shaped mounting bracket can drive the scraper to move and clean the surface of the filter screen.

[0008] Preferably, one end of the U-shaped mounting bracket is fixed with a handle, and the top and bottom of both sides of the U-shaped mounting bracket are provided with communicating limiting holes.

[0009] Preferably, the limiting mechanism includes a box fixed to one end of both sides of the oil inlet tank, and both sides of the U-shaped mounting bracket are adapted to the inside of the box. A limiting rod is slidably provided through the top of the two boxes, and the limiting rod is adapted to the limiting hole. When the limiting rod is inserted into the limiting hole, it will limit the U-shaped mounting bracket.

[0010] Preferably, a fixing block is fixed to the top of the limiting rod, one end of a spring is fixed to the bottom of the fixing block, the other end of the spring is fixedly connected to the top of the insertion box, and the spring is located on the outer surface of the limiting rod.

[0011] Preferably, the purification mechanism includes a cover plate fixed to the top of the oil inlet tank, an air pump installed on the top of the cover plate, the air inlet of the air pump being connected to and communicating with the interior of the oil inlet tank through a conduit, a purification box fixed to one end of the top of the cover plate, activated carbon layers being provided at both ends of the interior of the purification box, an adsorption layer being provided on the side of the two activated carbon layers that are close to each other, and an air outlet being provided at the other end of the purification box, the air outlet of the air pump being connected to an air outlet pipe, and the other end of the air outlet pipe being connected to and communicating with one end of the purification box.

[0012] Preferably, an oil pump is installed at one top end of the base plate, the oil pump is connected to an oil inlet pipe at its inlet end, the other end of the oil inlet pipe is connected to and communicates with an oil outlet tank, the oil pump is connected to an oil outlet pipe at its outlet end, and the other end of the oil outlet pipe is connected to and communicates with the top of one end of the oil inlet tank.

[0013] Preferably, a tie rod is fixed to the top end of the base plate away from the oil pump, and casters are installed at the four corners of the bottom of the base plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of a cleaning mechanism, after the filter screen filters impurities in the oil, some sediment and impurities will remain on the surface of the filter screen. Pulling the handle will move the fixed rod and slider, which in turn will move the scraper to clean the surface of the filter screen. The residue will then be discharged from the channel at one end of the oil inlet, thus cleaning the filter screen, ensuring its normal operation, improving the filtration efficiency of impurities in the oil, extending the service life of the filter screen, and improving the quality of the oil.

[0016] 2. Due to the adoption of a purification mechanism, harmful gases generated during oil discharge from the oil tank are extracted by an air pump and then transported to the purification chamber through an exhaust pipe. The gases are purified by the activated carbon layer and adsorption layer before being discharged. This effectively reduces the pollution of harmful gases to the environment, protects the surrounding environment, and improves the safety and reliability of the equipment.
