[0002] Existing oil pumping and material isolators are mainly simple sealed box structures that only provide a simple sealed environment for the oil tank that needs to be pumped or filled. The entire oil pumping process is manually operated. When pumping oil, the oil pumping pipe needs to be manually installed. The entire process is relatively cumbersome. When the oil releases harmful gases, the existing oil pumping and material isolators have no control measures for the passive discharge of gases, which can easily pollute the surrounding environment and further damage the health of the operators. At the same time, due to the large size of the oil drum and the heavy oil loaded, the oil drum needs to be placed in the isolator for extraction. This process is not easy to operate and requires more operators to assist to complete, which is very inconvenient. Therefore, an automated control structure is urgently needed to solve the problems existing in the above background. Summary of the Invention

[0030] The present application is further described in detail below with reference to the accompanying drawings. In the description of this embodiment, unless otherwise specified, the terms "left" and "right" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the product structure referred to in this application must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] In one embodiment, Figure 1 and Figure 4As shown, the automatic oil extraction and material discharging isolation device provided by the present invention mainly includes a box body 400, a feeding component 100, a discharging component 300, an electrically controlled exhaust component 200 and an oil extraction pipe 305. Specifically, a accommodating chamber 403 is provided in the box body 400. The accommodating chamber 403 is used to place an oil barrel 402. The oil barrel 402 is generally used to load liquids such as benzene, formalin or methanol. Such liquids are easy to volatilize harmful gases or gases with pungent odors. When the material is extracted, the box body 400 is in a sealed state and does not circulate with the outside air; the feeding component 100 is provided with a lifting platform 104. During the placement of the oil barrel 402, the oil barrel 402 is first placed on the lifting platform 104, and then raised to a preset height by the lifting platform 104. Then, the oil barrel 402 is moved from the lifting platform 104 to the accommodating chamber 403 of the box body 400. The oil pumping pipe 305 is mainly used for pumping oil and is movably arranged on the box body 400. The oil pumping pipe 305 can move up and down relative to the oil tank 402 and the box body 400. The up and down directions referred to here are the axial directions of the oil pumping pipe 305. One end of the oil pumping pipe 305 can be fully extended to the bottom of the oil barrel 402. At the same time, one end of the oil pumping pipe 305 can also be completely separated from the oil barrel 402, which is convenient for the replacement of the oil barrel 402.

[0032] The feeding assembly 300 is fixedly connected to the end of the oil extraction pipe 305 away from the oil barrel 402, driving the oil extraction pipe 305 to move up and down so that one end of the oil extraction pipe 305 can be moved out of the oil barrel 402 under the automated equipment or one end of the oil extraction pipe 305 can be inserted into a newly replaced oil barrel 402; the electrically controlled exhaust assembly 200 is arranged on the outer surface of the box body 400 and is connected to the accommodating cavity 403 in the box body 400 to monitor the gas in the box body 400, mainly including the oxygen content of the gas in the box body 400 and the air pressure detection in the box body 400, and diluting, filtering and discharging the harmful gas in the box body 400 to prevent the harmful gas from flowing out of the box body 400 and directly convecting with the air, causing harm to the operator and environmental pollution. In this embodiment, by setting up a loading component 100, the oil barrel 402 can be lifted and lowered, and the oil barrel 402 can be pushed to any position, and the height of the lifting platform 104 is adjustable. After adjusting to a suitable height, it is more convenient for the operator to replace the oil barrel 402 into the box body 400, without the need for multiple people to lift it, the required operating space is smaller, and the operability is flexible and strong; by arranging the oil extraction pipe 305 movably and connecting it to the feeding component 300, the feeding component 300 drives the oil extraction pipe 305 to be raised and lowered, so that the oil extraction pipe 305 can be automatically lifted and lowered. Compared with traditional manual operation, the efficiency is higher and more convenient, and the operator can be protected to avoid direct contact with the oil extraction pipe 305; by setting up an electrically controlled exhaust component 200, the gas in the box body 400 can be effectively monitored, and the harmful gas in the box body 400 can be diluted and filtered, and discharged outside the box body 400 after reaching a safe value, without affecting the health of the operator and playing a certain protective role in the environment.

[0033] In one embodiment, Figure 2 and Figure 3As shown, the loading assembly 100 also includes a base 106, a first driving mechanism 101, a first lifting link 102, and a second lifting link 103. Specifically, a universal wheel 1062 is provided below the base 106, which can facilitate the loading assembly 100 to drive the oil barrel 402 to move to any position. The first driving mechanism 101 is provided on the base 106, and the output end of the first driving mechanism 101 is movably connected to one end of the first lifting link 102, and the other end of the first lifting link 102 is movably connected to the lifting platform 104. In this embodiment, the other end of the first lifting link 102 is hinged to the lifting platform 104; the second lifting link 103 is hinged to the first lifting link 102, and the hinge point 105 is located in the middle position of the first lifting link 102 and the second lifting link 103; in this embodiment, the first lifting link 102 and the second lifting link 103 have the same structure. When the hinge point 105 is in the middle position, the first lifting link 102 and the second lifting link 103 are lifted and lowered synchronously, and both can effectively support the lifting platform 104; one end of the second lifting link 103 is movably connected to the base 106, and the other end of the second lifting link 103 is movably connected to the lifting platform 104. Specifically, the second lifting link 103 is hinged to the base 106, and the other end is in rolling contact with the lifting platform 104 through the first guide wheel 1031. A first guide groove 1042 that is adapted to the width of the first guide wheel 1031 is provided on the lifting platform 104, and the first guide wheel 1031 is clamped in the first guide groove 1042, wherein the direction of the first guide groove 1042 is consistent with the moving direction of the second guide wheel 1011. It should be pointed out that the support structure composed of the first lifting link 102 and the second lifting link 103 is symmetrically arranged about the lifting platform 104, and is located on both sides of the lifting platform 104, such as Figure 5As shown, the same supporting structure is provided on the other opposite side of the lifting platform 104. The output end of the first driving mechanism 101 is a hydraulic push rod, on which a second guide wheel 1011 is provided, a guide gear 1012 is provided at the front end of the second guide wheel 1011, and a guide rack 1061 is provided on the base 106 to be adapted to mesh with the guide gear 1012. The installation direction of the guide rack 1061 is consistent with the direction of the first guide groove 1042. Optionally, the matching structure of the first guide wheel 1031 and the first guide groove 1042 and the matching structure of the second guide wheel 1011, the guide gear 1012 and the guide rack 1061 can also be achieved by replacing the structure of the slider groove. By providing the guide gear 1012 and the matching guide rack 1061, when the position of the lifting platform 104 is adjusted to the preset position, the guide gear 1012 can play a certain positioning role and provide a certain resistance to prevent the second guide wheel 1011 from rotating and slipping, causing instability of the entire lifting mechanism. In this embodiment, the first lifting link 102 and the second lifting link 103 are both configured as rolling connections at the ends close to the first drive mechanism 101. Optionally, the ends of the first lifting link 102 and the second lifting link 103 away from the first drive mechanism 101 are configured as rolling connections, and the ends of the first lifting link 102 and the second lifting link 103 close to the first drive mechanism 101 are configured as hinged connections. In this embodiment, the first drive mechanism 101 is a hydraulic system that is symmetrically distributed on both sides of the lifting platform 104 to facilitate the operator's synchronous control of the lifting and lowering of the link assemblies on both sides of the lifting platform 104. Optionally, the hydraulic system can also be implemented by a servo motor or a steering gear combined with a screw slider structure. It is understandable that the type of the first driving mechanism 101 and the lifting method of the lifting platform 104 are not limited by the present invention, as long as the lifting platform 104 can be adjusted to a preset position.

[0034] In one embodiment, Figure 4As shown, in order to further facilitate the operator to move the oil drum 402 into the box body 400 or remove the oil tank 402 from the box body 400, a plurality of first guide rollers 1041 are provided on the lifting platform 104, and a plurality of second guide rollers 401 are provided on the placement position in the accommodating cavity 40 of the box body 400. When the lifting platform 104 is adjusted to a preset position, the position of the first guide roller 1041 corresponds to the position of the second guide roller 401, and the distance between adjacent first guide rollers 1041 and second guide rollers 401 is small, which meets the requirement of the oil drum 402 rolling back and forth on the first guide roller 1041 and the second guide roller 401; at the same time, the plurality of first guide rollers 1041 and the plurality of second guide rollers 401 are in the same plane, which is convenient for the operator to directly push the oil drum 402 to move on the first guide roller 1041 and the second guide roller 401. For the heavy oil drum 402 filled with materials, there is no need for multiple people to lift it at the same time, which reduces the number of operators required and the operation method is relatively safe. Optionally, rollers or guide rollers can be set at the bottom of the oil tank 402, that is, the lifting platform 104 and the placement position in the box 400 are planar structures. As long as the two are on the same plane, the purpose of easily moving the oil barrel 402 can be achieved.

[0035] In one embodiment, Figure 7 and Figure 8 As shown, the punching assembly 300 includes a second drive mechanism 306, a push rod 301 and a lifting cross bar 304. One end of the lifting cross bar 304 is fixedly connected to one end of the push rod 301, the other end of the lifting cross bar 304 is fixedly connected to the oil pumping pipe 305, and the other end of the push rod 301 is connected to the output end of the second drive mechanism 306. The second drive mechanism 306 drives the push rod 301 to rise and fall, thereby driving the lifting cross bar 304 to rise and fall, thereby driving the oil pumping pipe 305 to rise and fall. In this embodiment, the second drive mechanism 306 is a combination structure of a cylinder, a hydraulic cylinder or a servo motor combined with a screw slider, and the relative movement of the slider relative to the screw drives the push rod 301 to rise and fall. Furthermore, in order to strengthen the connection strength of the lifting cross bar 304, reinforcing ribs are provided on the lifting cross bar 304 to meet the lifting and lowering requirements of the oil pumping pipe 305.

[0036] Furthermore, if Figure 8As shown, since the oil extraction pipe 305 has a certain length, the stroke of the push rod 301 is relatively long. To ensure the structural stability of the entire punching assembly 300, a guide sleeve 302 and a guide shaft 303 are provided on the side of the push rod 301, which are parallel to the moving direction of the push rod 301. The guide sleeve 302 is fixedly provided on the housing 400, and the guide shaft 303 is provided in the guide sleeve 302. The guide sleeve 302 has a certain length, and the guide shaft 303 can move axially relative to the guide sleeve 302, moving synchronously with the push rod 301. Furthermore, to reduce the resistance of the oil extraction pipe 305 during the lifting process, the axis direction of the oil extraction pipe 305 is provided parallel to the axis direction of the push rod 301. In this embodiment, there are two guide shafts 303 and guide sleeves 302, which are symmetrically distributed on both sides of the push rod 301. One end of the guide shaft 303 is fixedly connected to the push rod 301 through a connecting piece and moves synchronously with the push rod 301. The other ends of the two guide shafts 303 are also fixedly connected into a whole through a connecting piece. Through this structural setting, the stability of the lifting and lowering action of the oil pumping pipe 305 is further improved.

[0037] In one embodiment, the extracted oil may be toxic, such as the aforementioned liquids such as benzene, formalin, and methanol. Figure 4 and Figure 5 As shown, when the oil extraction pipe 305 is raised from the oil tank 402, a portion of the oil extraction pipe 305 is exposed to the air. Therefore, a retractable sealing sleeve 3053 is provided on the portion of the oil extraction pipe 305 located outside the tank 400. One end of the sealing sleeve 3053 is fixedly connected to the oil extraction pipe 305, and the other end is fixedly connected to the outside of the tank 400. When the oil extraction pipe 305 is raised or lowered, the sealing sleeve 3053 can be retracted and retracted synchronously with the oil extraction pipe 305, ensuring that the oil extraction pipe 305 remains within the sealing sleeve 3053 and is not exposed to direct contact with the air. In this embodiment, the sealing sleeve 3053 is a polytetrafluoroethylene tube. Alternatively, the sealing sleeve 3053 can be made of another elastic sealing material that has a certain degree of corrosion resistance and does not chemically react with the oil or gas. It is understandable that the material of the sealing sleeve 3053 is not limited by the present invention. The actual function of the sealing sleeve 3053 is to prevent the oil pumping pipe 305 from being directly exposed to the air and to prevent the volatilization and leakage of harmful gases.

[0038] In one embodiment, again referring to Figure 4In order to further deal with the oil stains remaining outside the pipe wall when the oil extraction pipe 305 rises, an air drying component is set outside the oil barrel 402 in the box body 400. The air drying component mainly includes an air drying sleeve 3051 and an air blowing hole 3052 set on the air drying sleeve 3051. Under the action of the material breaking component 300, the oil extraction pipe 305 can move axially relative to the air drying sleeve 3051. Specifically, the air-drying sleeve 3051 is a cylindrical structure sleeve, the upper end of the air-drying sleeve 3051 is fixed to the upper side wall inside the box body 400, the diameter of the air-drying sleeve 3051 is larger than the diameter of the oil extraction pipe 305, and a through hole matching the diameter of the oil extraction pipe 305 is provided at the lower end of the air-drying sleeve 3051 to facilitate the insertion and movement of the oil extraction pipe 305. Furthermore, in order to facilitate disassembly and installation, and to facilitate regular cleaning of residual oil stains in the air-drying sleeve 3051, the air-drying sleeve 3051 is set into a detachable structure and is connected to the upper wall inside the box body 400 by threads. The air hole 3052 is arranged on the side of the air-drying sleeve 3051 close to the upper wall of the box body. The air hole 3052 is connected to the air pump through a quick-screw straight-through structure. In this embodiment, since the oil will emit toxic or irritating gases, the gas source is an inert gas such as nitrogen, which plays a protective role against harmful gases or gases with irritating odors and prevents high-concentration harmful gases from being directly discharged out of the boundary.

[0039] In one embodiment, reference Figure 5 and Figure 6The electric control exhaust assembly 200 includes a control unit, a sensor, an air inlet 201, an air outlet 202 and an exhaust fan 203. The air inlet 201 is arranged on the outside of the box body 400 and communicates with the accommodating cavity 403 inside the box body 400. The air outlet 202 is arranged on the outside of the box body 400 and communicates with the accommodating cavity 403 inside the box body 400. The exhaust fan 203 is arranged on the outside of the box body 400 near the air outlet 202. The air inlet of the exhaust fan 203 is connected to the air outlet 202 on the box body 400, and the air outlet of the exhaust fan 203 is connected to the The outside world is connected, and the sensor is set in the box. The sensor is communicated with the control unit through the sensor interface 2014. The sensor is mainly used to detect the air pressure and oxygen content in the box, and feed back the measured data to the control unit. The control unit is used to receive the data detected by the sensor and send instructions to control the exhaust fan 203 to perform exhaust work or nitrogen replenishment. Among them, filtering devices are set on the air inlet 201 and the air outlet 202 to filter the gas volatilized by the oil during oil extraction, and it can be discharged out of the box only after reaching the safety threshold. Furthermore, a nitrogen inlet 2013 is provided on both the air inlet 201 and the air outlet 202. The nitrogen inlet 2013 is mainly used to supply nitrogen to the box body 400 to reduce the concentration of volatile gas from the oil. The sensor interface 2014 is mainly used to connect the sensor located in the box body to the control unit located outside the box body for communication. The data detected by the sensor is fed back to the control unit in a timely manner. The control unit compares the feedback data with the set threshold value to thereby control the exhaust fan 203 to exhaust air and replenish nitrogen in the box body 400.

[0040] In one embodiment, an air inlet 2011 is further provided on the air inlet 201, and a first valve 2012 is provided between the air inlet 2011 and the air inlet; specifically, the air inlet 2011 is a passive air intake, and when the air pressure in the box 400 is low, the first valve 2012 opens, and under the action of the pressure difference, air automatically flows into the box 400 through the air inlet 2011 to balance the air pressure in the box 400. The first valve 2012 is an electrically controlled valve or a pneumatic valve, and its automatic opening or closing is controlled by the control unit. Furthermore, a second valve 2023 is provided on the air outlet 202. The principle of the second valve 2023 is similar to that of the first valve 2012. It is also an automatic valve controlled by the control unit. When nitrogen is replenished, since the air inlet 201 and the air outlet 202 are in a normally open state, the entire box 400 needs to be sealed, so the first valve 2012 and the second valve 2023 need to be closed. After the concentration of harmful gases or gases with pungent odors is diluted, the air pressure in the box 400 increases, and the first valve 2012 and the second valve 2023 are opened to balance the air pressure in the box 400.

[0041] In one embodiment, the present invention further provides an operating procedure of an automated oil pumping and material separation device, which is specifically as follows:

[0042] The operator pushes the loading car with the oil drum 402, which is the aforementioned loading assembly 100, to the discharge port of the box body 400, opens the sealing door of the box body 400, adjusts the relative positions of the first guide roller 1041 and the second guide roller 401, so that the first guide roller 1041 and the second guide roller 401 are on the same plane, and then the operator pushes the oil tank 402, moves the oil tank 402 from the first guide roller 1041 to the second guide roller 401, closes the sealing door of the box body 400, and drives the oil pumping feeding pipe 305 to descend through the feeding assembly 300 until the oil pumping feeding pipe 305 reaches the bottom of the oil tank, and then extracts the oil. After the oil extraction is completed, the feeding assembly 300 drives the oil pumping feeding pipe 305 to rise until the oil pumping feeding pipe 305 reaches the bottom of the oil tank. The material pipe 305 is separated from the oil tank 402. During the rising process of the oil pumping and material feeding pipe 305, nitrogen is blown into the blowing hole 3052 to air-dry the oil pumping and material feeding pipe 305. At the same time, during the whole process, after the box body 400 is sealed, the electronically controlled exhaust component 200 starts to work to detect the gas in the box body 400. The detection index includes the oxygen content and the air pressure in the box body. Nitrogen is flushed into the electronically controlled exhaust component 200 to protect the harmful gas. At the same time, the air enters to dilute the harmful gas and discharge the harmful gas through the air outlet 202 with a filtering device. At the same time, the air pressure in the box body 400 is adjusted until it is in a normal preset state. Then, the sealed door of the box body 400 is opened, the empty oil tank 402 is pushed out, and the next cycle operation is entered.

[0043] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention. Such improvements and modifications should also be considered within the scope of protection of the present invention.
