Description

Technical Field

[0001] The present invention relates to the technical field of oil tank exhaust technology, and in particular to an oil tank exhaust device. Background Art

[0002] Gasoline is a colorless liquid with a peculiar odor. It is flammable and explosive and has strong volatility. When the concentration of gasoline in the air reaches a certain value, safety accidents are very likely to occur. Therefore, oil tanks used to store gasoline in oil depots must pay special attention to the problem of gasoline volatilization.

[0003] Publication number CN211033812U discloses an exhaust device for a gasoline tank depot, which includes an oil depot, wherein the upper end of the side wall of the oil depot is connected to a horizontally arranged exhaust pipe, and the volatilized gas in the oil depot is discharged from the exhaust pipe. A gas flow sensor for detecting the gas flow through the exhaust pipe is installed on the exhaust pipe, and the other end of the exhaust pipe is connected to an air guide pipe composed of a continuous positive U-shaped pipe and an inverted U-shaped pipe, and silicone oil is filled in the internal cavity at the bend of the positive U-shaped pipe. The device uses silicone oil in the air guide pipe, which has heat resistance and electrical insulation, etc., and can well isolate the air in the oil depot from the outside air, so that the oil depot does not come into contact with the outside air; however, when the patent application is in use, the volatilized gas in the oil depot is only discharged through the exhaust pipe alone, and the air is not simultaneously transported into the oil depot to maintain the pressure balance in the oil depot, which can easily cause a negative pressure situation inside the oil depot, and then cause the gasoline in the oil depot to become unstable, posing a great safety hazard.

[0012] Preferably, a limiting assembly is provided on the collection tank, and the limiting assembly includes a limiting rod and a pad.

[0013] The at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects: First, when the oil tank exhaust device in the prior art is in operation, the volatilized gas in the oil tank is only discharged through the exhaust pipe alone, and air is not simultaneously supplied into the oil tank to maintain the pressure balance in the oil tank. This can easily cause a negative pressure inside the oil tank, which in turn causes the gasoline in the oil tank to become unstable, posing a great safety hazard. The exhaust component in this device can separate the interior of the collection tank into two spaces, upper and lower. Over time and due to external factors, some of the gasoline in the oil tank will evaporate and produce a certain amount of gas. When the pressure sensor detects that the pressure inside the oil tank is above atmospheric pressure, it can start the drive mechanism to drive the control component to operate. At the same time, the control component can drive the exhaust component to rise a certain distance in the collection tank, and the adjustment component will rise synchronously with the movement of the exhaust component, and control the four sealing components to push up at the same time, so that the two sealing components on the left side of the collection tank will form a blocking effect on the air inlet pipe and the exhaust gas outlet pipe, while the two sealing components on the right side of the collection tank will not form a blocking effect on the air outlet pipe and the exhaust gas inlet pipe. At the same time, the volatilized gas in the oil tank will be drawn into the lower half of the space in the collection tank as the exhaust component rises, and the air originally in the upper half of the space in the collection tank will be sent into the oil tank by the exhaust component, filling the space in the oil tank after the gas is extracted, so that the pressure in the oil tank remains balanced; When the driving mechanism drives the control component to continue running, the control component can drive the exhaust component and the adjustment component to descend a certain distance. At this time, the control component can push the four sealing components downward at the same time, so that the two sealing components on the left side of the collection tank will not form a blocking effect on the air inlet pipe and the exhaust gas exhaust pipe, while the two sealing components on the right side of the collection tank will form a blocking effect on the air outlet pipe and the exhaust gas inlet pipe. At the same time, as the exhaust component descends, air will be sucked into the upper half of the space in the collection tank from the air inlet pipe, and the volatile gas drawn into the lower half of the space in the collection tank will be transported by the exhaust component from the exhaust gas exhaust pipe to the exhaust gas reservoir, and finally the volatile gas in the exhaust gas reservoir will be centrally treated; This device can cooperate with the control component through the driving mechanism to drive the exhaust component and the adjustment component to rise and fall, so that the adjustment component can control the four sealing components to switch the opening or closing states of the air inlet pipe, the air outlet pipe, the exhaust gas inlet pipe and the exhaust gas outlet pipe respectively, and then cooperate with the exhaust component to compress the space in the collection tank in different states, so that the volatile gas in the oil tank can be extracted while air can be transported into the oil tank to fill the space in the oil tank after the gas is extracted, so that the pressure in the oil tank remains balanced, avoiding negative pressure inside the oil tank, and thus preventing safety hazards caused by unstable pressure in the oil tank.

[0014] Secondly, the pressure plate in the present device can divide the interior of the collection tank into two spaces, an upper part and an lower part. When the motor drives the driving plate to rotate on the driving bracket, the driving shaft will move within a certain range in the guide groove of the adjusting member as the driving plate rotates. When the motor drives the driving shaft on the driving plate to rotate clockwise from bottom to top, the driving shaft will form a certain traction force on the adjusting member while moving in the guide groove, and pull the adjusting member upward, so that the pressure rod can drive the pressure plate to rise in the collection tank, thereby enabling the pressure plate to compress the upper half of the space in the collection tank, and cooperate with four sealing members to respectively control the air inlet pipe, the air outlet pipe, the exhaust gas inlet pipe and the exhaust gas outlet pipe, so as to realize the process of transporting air from the collection tank to the oil tank, and drawing volatile gases in the oil tank into the collection tank; Secondly, when the motor drives the drive shaft on the drive disk to rotate clockwise from top to bottom, the drive shaft will move in the guide groove while forming a downward thrust on the adjusting part, and pull the adjusting part downward, so that the pressure rod can drive the pressure plate to descend in the collection tank, so that the pressure plate can compress the lower half of the space in the collection tank, and again cooperate with the four seals to control the air inlet pipe, air outlet pipe, exhaust gas inlet pipe and exhaust gas outlet pipe respectively, to realize the process of sucking air into the collection tank and transporting the volatile gas drawn into the collection tank to the exhaust gas storage.

[0015] Third, the present invention is provided with an adjustment component. When the pressure rod is raised or lowered, the adjustment frame can drive the first support member and the second support member to rise or fall synchronously, and control each sealing component to maintain synchronous movement. Then, when only one driving force is used, each sealing component can respectively control the intake pipe and the exhaust gas discharge pipe, the outlet pipe and the exhaust gas inlet pipe to switch to the synchronous opening or closing state.

[0016] Fourthly, a return spring is provided between each of the sealing members and the corresponding first support member and the second support member. As the pressure rod rises, the adjustment frame can drive the first support member and the second support member to move synchronously. At this time, the two return springs on the first support member can push the corresponding two seals into the intake pipe and the exhaust pipe, and make the two seals on the first support member and the corresponding intake pipe and exhaust pipe form a closed state. As the pressure rod continues to rise, the pressure plate will compress the upper half of the space in the collection tank. At this time, the first support member will continue to rise for a distance and apply pressure to the two return springs at the intake pipe and the exhaust pipe. Under the tension of the two return springs, the corresponding two seals on the first support member can always be pressed against the intake pipe and the exhaust pipe. At the same time, the second support member will drive its corresponding two seals to be pulled out from the exhaust pipe and the exhaust gas inlet pipe, and the two return springs on the second support member will pull the corresponding two seals so that the corresponding two seals will not separate from the second support member. Through the mutual cooperation between the first support member and the second support member and the corresponding return springs, each seal can be controlled to switch the intake pipe, exhaust pipe, exhaust gas inlet pipe and exhaust gas discharge pipe to open and close states respectively while the pressure rod is raised and lowered, so that the pressure plate can control the collection tank to normally exchange the volatile gases in the air and oil tank.
