Description

Technical Field

[0001] The utility model relates to the technical field of waste oil discharge and collection, in particular to a mobile closed oil tank retractable device. Background Art

[0002] Waste oily water is a kind of waste that is extremely harmful to the environment. If it is not treated, it will cause serious pollution to the environment. Recycling waste oily water can not only reduce environmental pollution, but also make full use of useful materials and save energy. At present, the recycling of waste oily water, especially viscous oily water, mainly relies on manual recycling. However, there are the following shortcomings in the actual recycling process:

[0003] 1. Manually carry buckets to various discharge points for recycling on site. Open the sewage valve of the tanker truck, and the viscous oil and water will directly enter the bucket through the process pressure. However, there are some problems: when recycling the viscous oil and water, the process pressure will cause it to splash out of the bucket during recycling. In addition, this method also has pollution problems in actual application.

[0004] 2. There are also some problems when recycling viscous oil and water on site and pouring them into the sewage recovery pool: this process requires manual pouring into the sewage pool. Since the recycled oil and water are viscous and adhere to the whole body, the bucket will not be emptied cleanly, thereby reducing on-site work efficiency.

[0005] Therefore, it is necessary to design a mobile closed oil tank retracting and releasing device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies and design a mobile closed oil tank retractable device, which solves the problem of on-site pollution, avoids the problems of oil and water falling to the ground and the problem of viscous oil and water not being drained cleanly, improves work efficiency and saves labor costs. The specific technical solution is as follows:

[0007] A mobile closed oil tank retractable device comprises a closed oil tank and a trolley. The closed oil tank is placed on the trolley. A liquid inlet valve, a three-way valve and a pressure gauge are provided on the top of the closed oil tank, a drain valve is provided on the bottom, an air pump is provided on one side, and a liquid level gauge is provided on the other side. The liquid inlet valve and the on-site sewage discharge process are connected through a hose quick connector. When the switches of the three-way valve and the drain valve are opened, the dirty oil and water are transported into the closed oil tank by the process pressure. The drain valve discharges the oil and dirt in the closed oil tank to an external sewage pool through the hose quick connector. The air pipe of the air pump is connected to the three-way valve. By turning on the air pump, the closed oil tank is pressurized, and the viscous oil and dirt inside the tank body of the closed oil tank are discharged to the external sewage pool through the drain valve by the tank pressure.

[0008] Preferably, the specific model of the pressure gauge is a stainless steel shock-resistant pressure gauge Y-60BF with a measuring range of 0-1.6 MPa. The pressure gauge displays the internal pressure of the closed retractable oil tank. When the pressure on the pressure gauge reaches 0.5-0.8 MPa, the drain valve is opened to discharge the oil.

[0009] Preferably, the liquid level gauge is an explosion-proof and pressure-resistant liquid level gauge, the specific model is the explosion-proof and pressure-resistant liquid level gauge B42X-2.5, the measuring range L=330mm, and the liquid level inside the tank body of the closed retractable oil tank is monitored by the liquid level gauge. When the liquid level of the liquid level gauge reaches the 2 / 3 position displayed, the drain valve is opened to discharge the oil.

[0010] Preferably, the air pump is a rechargeable air pump, which is used to increase the pressure inside the closed retractable oil tank.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1 , the utility model provides a technical solution:

[0017] A mobile closed oil tank retractable device comprises a closed oil tank 3 and a trolley 8. The closed oil tank 3 is placed on the trolley 8. A liquid inlet valve 2, a three-way valve 5 and a pressure gauge 4 are provided on the top of the closed oil tank 3, a drain valve 7 is provided on the bottom, an air pump 6 is provided on one side, and a liquid level gauge 1 is provided on the other side; the liquid inlet valve 2 and the on-site sewage discharge process are connected through a hose quick connector, and the switches of the three-way valve 5 and the drain valve 7 are opened to transport the dirty oil and water into the closed oil tank 3 through the process pressure; the drain valve 7 discharges the oil and dirt in the closed oil tank 3 to an external sewage pool through a hose quick connector; the air pipe of the air pump 6 is connected to the three-way valve 5, and the closed oil tank 3 is pressurized by opening the air pump 6, and the viscous oil and dirt inside the tank body of the closed oil tank 3 are discharged to the external sewage pool through the drain valve 7 through the tank pressure. The device is fully automated in the process of recovering and discharging oil, saving labor costs. When recovering oil and water on site, they are directly connected to the liquid inlet valve through a hose quick connector, and closed recovery effectively solves the pollution problem, ensuring that the oil and water do not fall to the ground. When the oil is discharged into the sewage pool, the tank is pressurized through the device's rechargeable air pump, and the viscous oil and water inside the tank are automatically discharged into the sewage pool by the internal pressure of the tank, thereby improving work efficiency.

[0018] Furthermore, the specific model of the pressure gauge 4 is a stainless steel shock-resistant pressure gauge Y-60BF with a measuring range of 0-1.6 MPa. The pressure inside the closed retractable oil tank 3 is displayed by the pressure gauge 4. When the pressure of the pressure gauge 4 reaches 0.5-0.8 MPa, the drain valve 7 is opened to discharge the oil.

[0019] Furthermore, the liquid level gauge 1 is an explosion-proof and pressure-resistant liquid level gauge, the specific model is the explosion-proof and pressure-resistant liquid level gauge B42X-2.5, the measuring range L=330mm, and the liquid level inside the tank body of the closed retractable oil tank 2 is monitored by the liquid level gauge 1. When the liquid level of the liquid level gauge 1 reaches the displayed 2 / 3 position, the drain valve 7 is opened to discharge the oil.

[0020] Furthermore, the air pump 6 is a rechargeable air pump, which is used to increase the pressure inside the closed retractable oil tank 3 .

[0021] The working principle of the on-site oil and water collection of the utility model is as follows: the on-site sewage discharge process and the liquid inlet valve 2 of the closed retractable oil tank 3 are connected through a hose quick connector. At this time, the three-way valve 5 (for exhaust) for air inlet and outlet on the top of the tank body is opened, and the sewage valve 7 is opened to transport the dirty oil and water into the tank body of the closed retractable oil tank 3 through the process pressure.

[0022] The working principle of the on-site oil-water discharge of the present invention is as follows: since the oil and water collected on-site are deposited at the bottom of the tank and have a certain viscosity that is difficult to discharge, the air pipe of the air pump 6 is connected to the three-way valve 5, and the air pump 6 is turned on to pressurize the tank body of the closed retractable oil tank 3 to a certain pressure (the pressure can be set). At this time, the drain valve 7 is opened, and the viscous oil and water inside the tank body are automatically discharged into the sewage pool through the tank pressure. The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field can still modify or make equivalent substitutions to the specific implementation methods of the present invention.
