As shown in fig. 1, the present invention provides an oil processing apparatus, which includes a vacuum generator 1, a compressed air source (not shown), an oil storage tank 6 and a visible oil storage chamber 61, wherein the visible oil storage chamber 61 is provided with an observation port (not shown), the bottom of the visible oil storage chamber is communicated with the top of the oil storage tank 6, when the oil storage tank 6 is filled with oil, the oil can enter the visible oil storage chamber 61, and a worker can observe whether oil enters the visible oil storage chamber 61 through the observation port to determine the oil amount in the oil storage tank 6, so as to prevent the oil from entering the vacuum generator 1. Two-two communication through communicating pipe between visual oil storage chamber 61, compressed air source and vacuum generator 1, and all be equipped with the stop valve on every communicating pipe. An oil pipe 3 is communicated with the oil storage tank 6, and a stop valve is also arranged on the oil pipe 3.
As shown in fig. 1 to 3, in an embodiment of the present invention, a compressed air source is communicated with a compressed air inlet 9, a first stop valve 11 is disposed on a communication pipe between the compressed air inlet 9 and the vacuum generator 1, a second stop valve 21 is disposed on a communication pipe 2 between the visible oil storage chamber 61 and the vacuum generator 1, a third stop valve 31 is disposed on the oil pipe 3, and a fourth stop valve 41 is disposed on a communication pipe 4 between the compressed air inlet 9 and the visible oil storage chamber 61.
In order to facilitate the oil replacement work at different places, the oil treatment device further comprises a moving trolley 7 with a plurality of rollers 71 arranged at the bottom, the vacuum generator 1 and the visible oil storage cavity 61 are respectively and fixedly arranged at the top of the oil storage tank 6, and the oil storage tank 6 is fixedly arranged on the moving trolley 7.
Preferably, the end of the vacuum generator 1 far away from the compressed air source is connected with an explosion-proof silencer 5, and the explosion-proof silencer 5 mainly plays two roles, namely, discharging a part of gas when the air pressure in the vacuum generator 1 exceeds a rated value, adjusting the internal pressure of the vacuum generator 1, ensuring the use safety, and reducing the noise generated by the high-speed flowing gas flow when the vacuum generator 1 works. The vacuum generator 1 is preferably a three-stage vacuum generator, and is connected with a negative pressure gauge, and the staff can judge the vacuum degree in the visible oil storage cavity 61 and the oil storage tank 6 by reading of the negative pressure gauge. The oil storage tank 6 is also connected with a digital display oil level sensor 8, and a worker can visually observe the liquid level in the oil storage tank 6 according to the numerical value of the digital display oil level sensor 8.
The invention also provides a using method of the oil treatment device, which comprises the following steps:
s1, pushing the movable trolley 7 to the position of an oil tank needing to replace waste oil, keeping all the stop valves closed, opening a compressed air source, opening the first stop valve 11 and the second stop valve 21, and starting to vacuumize the visible oil storage cavity 61 and the oil storage tank 6.
S2, when the reading of the negative pressure gauge on the vacuum generator 1 is smaller than the preset value, inserting the oil pipe 3 into an oil tank needing to replace waste oil, slowly opening the third stop valve 31 on the oil pipe 3, and observing the liquid level height in the oil storage tank 6 through the numerical value on the digital display oil level sensor 8 after the third stop valve 31 is completely opened. Specifically, the preset value is-0.04 MPa, and in the process of slowly opening the third stop valve 31 on the oil pipe 3, the reading on the negative pressure gauge is always kept less than-0.04 MPa, so that the oil absorption process is continuously and smoothly carried out.
S3, when the value on the display level sensor 8 is not changed or when an oil is introduced into the visual oil storage chamber 61 as seen from the observation port, the third stop valve 31, the second stop valve 21 and the first stop valve 11 are closed in this order, and the compressed air source is closed.
S4, pushing the moving trolley 7 to a container containing waste oil, keeping all the stop valves closed, opening a compressed air source, inserting the oil pipe 3 into the container containing the waste oil, and sequentially opening the third stop valve 31 and the fourth stop valve 41. Specifically, the oil discharge speed of the oil pipe 3 can be adjusted by adjusting the opening and closing amount of the fourth stop valve 41, and the larger the opening and closing amount of the fourth stop valve 41 is, the larger the gas flow rate in the visual oil storage cavity 61 and the oil storage tank 6 is in the same time period, the larger the pressure in the visual oil storage cavity 61 and the oil storage tank 6 is, the higher the oil discharge speed is, and otherwise, the slower the oil discharge speed is.
S5, when the oil pipe 3 does not discharge oil any more, the fourth stop valve 41 and the third stop valve 31 are closed in sequence, and then the oil pipe 3 is drawn out from the oil drum.
In step S3, if the numerical value on the digital display oil level sensor 8 does not change any more, it means that all the waste oil has been pumped out, and the operation is finished after step S5 is completed. If the oil is fed into the visible oil storage chamber 61 from the observation port, it means that the oil storage tank 6 is full of oil, but all the waste oil is not necessarily pumped out, so that after the step S5 is completed, the steps S1-S5 need to be repeated in sequence, and the operation cannot be finished until all the waste oil is pumped out.
In conclusion, the oil storage tank, the compressed air source and the vacuum generator are communicated in pairs, oil absorption and oil discharge are realized by utilizing negative pressure and positive pressure environments in the oil storage tank, the replacement efficiency of hydraulic oil is greatly improved, the device is simple in structure, safe and reliable, pollution caused by leakage in the hydraulic oil replacement process is reduced, the using method is simple and convenient, the labor intensity of workers is obviously relieved, and the working efficiency is improved; under the condition of arranging the visual oil storage cavity, whether the oil storage tank is full of oil or not can be observed visually, and the oil is prevented from entering the vacuum generator.
