Technical Field

[0001] The utility model relates to the technical field of oil and gas recovery, and particularly relates to an oil and gas recovery device for gas stations. Background Art

[0002] In recent years, the number of motor vehicles in China has been growing rapidly, and the consumption of refined oil has also increased rapidly. Due to the strong volatility of the light components in refined oil, a large amount of oil vapor is volatilized in gas stations. These oil vapors are volatile organic compounds, which are one of the main causes of excessive PM2.5 and haze weather. In addition, due to the flammable and explosive characteristics of oil vapor, the emission of oil vapor also poses a threat to the safe operation of gas stations.

[0003] After retrieval, the patent document with the publication number of CN220032903U proposes a three - stage oil and gas recovery device: The utility model relates to the field of oil and gas recovery related equipment, and particularly to a mobile three - stage oil and gas recovery device. It aims to solve the problem that in the prior art, when the oil and gas recovery device is maintained once, the whole set of equipment must be shut down for diagnosis, which increases the operation cost of gas stations. In the utility model, a telescopic column is installed below the shell, a hanging buckle is arranged at the piston end of the telescopic column, and the hydraulic cylinder end is fixed on the mounting plate, and the mounting plate is fixed at the bottom of the side surface of the shell; on the outer side of the other side surface of the shell. Within the piston stroke, at least two lifting and lifting components are provided, and at least 1 anchoring cylinder is further provided outside the lifting and lifting components. The height of the anchoring cylinder is lower than the height of the hanging buckle, and an anchor rod is inserted into the anchoring cylinder, and the anchor rod and the hanging buckle are matched in shape and size. The advantages are as follows: Combined with a quick - release valve with good sealing effect, it realizes quick disassembly and maintenance and the temporary quick installation of a standby machine, and reduces the impact of equipment maintenance and repair on the operation cost of the whole gas station.

[0004] During the use of the above - mentioned technical solution, the outer shell itself can play a role in protection and ventilation. However, after long - term use, the equipment is often unable to be cleaned. Coupled with many cleaning dead corners and inevitable oil and gas leakage, a large amount of dust is easily adsorbed inside, resulting in the influence on the heat dissipation of the whole machine.

[0005] Therefore, it is very necessary to invent an oil and gas recovery device for gas stations to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an oil and gas recovery device for gas stations, which realizes the balance of heat dissipation and dust - proof functions through the cooperation of a mobile chassis and an adjusting mechanism, so as to solve the problem that in the prior art, the outer shell itself can play a role in protection and ventilation, but after long - term use, the equipment is often unable to be cleaned.

[0007] To achieve the above object, the present utility model provides the following technical solution: A gas recovery device for a gas station.

[0008] Preferably, a number of empty grooves are formed on the surface of the five-groove rotating wheel. A number of dust-proof and heat dissipation holes are installed on one side of the mobile chassis. The shape of the dust-proof and heat dissipation holes is the same as that of the empty grooves on the five-groove rotating wheel.

[0012] Preferably, an exhaust gas discharge pipe is fixedly connected to the top end of the air extraction pump and the exhaust gas discharge pipe penetrates and extends above the mobile chassis. A liquid discharge pipe is fixedly connected to one side of the air extraction pump away from the gas-liquid separator and the liquid discharge pipe penetrates and extends to one side of the mobile chassis away from the swivel arm tail. The cooperation of the air extraction pump and the liquid discharge pipe is used to separately transport different products.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are:

[0014] When the temperature inside the mobile chassis changes, the expansion liquid senses the heat inside the mobile chassis and expands, thereby driving the piston and the first transmission rod to rise along the inside of the sealing cylinder. Thus, the second transmission rod and the five-groove rotating wheel are driven to rotate by the first transmission rod, and then the coincidence degree between the five-groove rotating wheel and the empty groove of the dust-proof heat dissipation hole is changed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0024] The present utility model provides as Figures 1-5An oil and gas recovery device for gas stations shown in the figure includes a mobile chassis 1. An adjustment mechanism 2 is arranged inside the mobile chassis 1. The adjustment mechanism 2 includes a sealing cylinder 201 fixedly connected to the bottom wall of the mobile chassis 1. An expansion liquid 202 is filled inside the sealing cylinder 201. A heat insulation plate 203 is fixedly connected to one side of the sealing cylinder 201 close to the mobile chassis 1. The heat insulation plate 203 is used to prevent the expansion liquid 202 from being affected by the external temperature and increasing errors. A piston 204 is slidably connected inside the sealing cylinder 201. The top of the piston 204 is fixedly connected to a first transmission rod 205. The outer side of the top of the first transmission rod 205 is rotatably connected to a second transmission rod 206. A connection groove 207 is opened on one side of the second transmission rod 206 close to the first transmission rod 205. The top of the first transmission rod 205 is located inside the connection groove 207. One end of the second transmission rod 206 far from the first transmission rod 205 is rotatably connected to a five-groove rotating wheel 208. The piston 204 is used to drive the second transmission rod 206 and the five-groove rotating wheel 208 to move successively. The outer side of the five-groove rotating wheel 208 is rotatably connected to a rotating frame 209. The rotating frame 209 is fixedly connected to the inner side wall of the mobile chassis 1. The characteristics of the expansion liquid 202 are used to make the piston 204 and the first transmission rod 205 move to drive the five-groove rotating wheel 208 to rotate, so that the heat dissipation amplitude of the dust-proof and heat dissipation holes 210 can be adjusted according to the temperature inside the mobile chassis 1 to achieve the balance between heat dissipation and dust prevention. Several groups of empty grooves are opened on the surface of the five-groove rotating wheel 208. Several groups of dust-proof and heat dissipation holes 210 are installed on one side of the mobile chassis 1. The shape of the dust-proof and heat dissipation holes 210 is the same as the empty grooves on the five-groove rotating wheel 208. The overlapping part of the five-groove rotating wheel 208 and the dust-proof and heat dissipation holes 210 is used to control the size of the heat dissipation area. Through the cooperation of the mobile chassis 1 and the adjustment mechanism 2, when the temperature inside the mobile chassis 1 changes, the expansion liquid 202 senses the heat inside the mobile chassis 1 and expands, and then drives the piston 204 and the first transmission rod 205 to rise along the inside of the sealing cylinder 201. Thus, the second transmission rod 206 and the five-groove rotating wheel 208 are driven to rotate by the first transmission rod 205, and then the coincidence degree of the empty grooves of the five-groove rotating wheel 208 and the dust-proof and heat dissipation holes 210 is changed. The proportion of the heat dissipation and dust prevention functions is adjusted through the coincidence degree of the empty grooves to improve the service life of the structure.

[0025] Refer to the attached drawings of the specification Figures 1-5, one side of the mobile chassis 1 is fixedly connected with a swivel pipe tail 3. The bottom end of the swivel pipe tail 3 is fixedly connected with an elastic corrugated pipe 8. A spring is installed on the inner side wall of the elastic corrugated pipe 8. The elasticity of the elastic corrugated pipe 8 is used to buffer the connection of the swivel pipe tail 3. The bottom end of the elastic corrugated pipe 8 is fixedly connected with a vertical plug pipe 10. The bottom end of the vertical plug pipe 10 is fixedly connected with a filter rubber clamp 9. The filter rubber clamp 9 is used to reinforce the sealing performance of the structure, and the connection strength is reinforced through the vertical plug pipe 10 to prevent deformation. The bottom end of the filter rubber clamp 9 is fixedly connected with a gas-liquid separator 5. The gas-liquid separator 5 is fixedly connected to the bottom wall of the mobile chassis 1. One side of the gas-liquid separator 5 is fixedly connected with an air extraction pump 6. Oil-gas separation is realized through the gas-liquid separator 5. The top end of the air extraction pump 6 is fixedly connected with an exhaust gas discharge pipe 4, and the exhaust gas discharge pipe 4 penetrates and extends above the mobile chassis 1. One side of the air extraction pump 6 away from the gas-liquid separator 5 is fixedly connected with a liquid discharge pipe 7, and the liquid discharge pipe 7 penetrates and extends to the side of the mobile chassis 1 away from the swivel pipe tail 3. The cooperation of the air extraction pump 6 and the liquid discharge pipe 7 is used to separately transport different products. Through the cooperation of the swivel pipe tail 3, the elastic corrugated pipe 8, the filter rubber clamp 9 and the vertical plug pipe 10, the connection pressure between the swivel pipe tail 3 and the elastic corrugated pipe 8 is reduced by their cooperation. Through the cooperation of the filter rubber clamp 9 and the vertical plug pipe 10, the connection strength between the swivel pipe tail 3 and the filter rubber clamp 9 is reinforced, thereby preventing its deformation and further improving its compressive capacity.

[0026] The working principle of this utility model:

[0027] Refer to the attached instruction Figures 1-5 , when the temperature inside the mobile chassis 1 changes according to the working state, the expansion liquid 202 expands by sensing the heat inside the mobile chassis 1, and then drives the piston 204 and the transmission rod 205 to rise along the inside of the sealing cylinder 201. Thus, the second transmission rod 206 and the five-groove rotating wheel 208 are driven to rotate through the first transmission rod 205, and then the coincidence degree between the five-groove rotating wheel 208 and the empty groove of the dust-proof heat dissipation hole 210 is changed. When the temperature inside the mobile chassis 1 rises, the coincidence degree between the five-groove rotating wheel 208 and the empty groove of the dust-proof heat dissipation hole 210 is increased, thereby strengthening the heat dissipation function. When the temperature inside the mobile chassis 1 drops, the coincidence degree between the five-groove rotating wheel 208 and the empty groove of the dust-proof heat dissipation hole 210 is reduced, so that the five-groove rotating wheel 208 blocks the dust-proof heat dissipation hole 210, strengthening its dust-proof function to improve the service life of the structure. When the gas-liquid separator 5 is working, the oil-gas is introduced into the inside of the gas-liquid separator 5 through the cooperation of the swivel pipe tail 3 and the air extraction pump 6, and finally the exhaust gas and the oil liquid are discharged through the exhaust gas discharge pipe 4 and the liquid discharge pipe 7 respectively, so as to achieve the purpose of oil liquid recovery.

Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model.
