Technical Field
[0001] The utility model relates to the technical field of inner floating plates of oil tanks, in particular to an inner floating plate sealing device. Background Art
[0002] Various petrochemical liquids such as diesel and gasoline are easy to evaporate. In order to reduce the evaporation loss of the liquid medium stored in the oil storage tank and prevent the oil gas formed by evaporation from emitting to the outside of the oil storage tank, which causes serious environmental pollution and safety hazards, at present, an inner floating plate sealing device is mostly used to seal the oil storage tank. The inner floating plate is a floating top cover floating on the liquid surface of the oil tank and rising and falling with the oil. Using this inner floating top cover to cover the liquid surface is currently recognized as the most ideal, most economical and simple method to reduce the evaporation loss of oil products. By setting an inner floating plate on the liquid medium in the oil tank, the inner floating plate rises and falls accordingly with the liquid level of the liquid medium, which can effectively prevent the volatilization of the liquid medium in the oil storage tank.
[0003] Although the existing inner floating plate sealing device can solve the problem of volatilization of oil stored in the oil storage tank, there are still some problems that need to be solved. For example, during the sealing process of the existing inner floating plate sealing device, the gap between the inner floating plate and the barrel mouth of the oil storage tank cannot be tightly combined, which easily leads to the risk of internal oil overflowing from the gap or volatilizing; at the same time, when the oil storage tank is filled with oil, the existing inner floating plate sealing device is not smooth enough to discharge the gas from the oil storage tank, and the exhaust pipe cannot be closed in time as the oil is filled, and external impurities may enter the oil storage tank from the exhaust pipe, causing pollution to the oil in the tank. Therefore, an inner floating plate sealing device is proposed.
[0004] The existing patent (publication number: CN207671033U) discloses a floating plate inside an oil tank, which includes: a main body, a pressure relief device installed on the middle part of the main body, and a sealing ring installed on the outer edge of the main body. A pressure relief air chamber is formed between the pressure relief device and the main body. The main body is a disc-shaped structure with a through hole in the middle, and a sealing ring groove is provided on the outer edge of the main body. The pressure relief device includes a gas relief hood installed on the main body and relatively matched with the through hole, and a hinged door installed on the gas relief hood. A rubber sealing sleeve is sleeved on the outer edge of the hinged door. A sealing ring strip is provided on the inner wall of the sealing ring, and the sealing ring strip is adapted to be installed in the sealing ring groove. In the floating plate inside the oil tank, low-density gas will be discharged through the hinged door, and part of the oil-gas mixture will stay in the pressure relief air chamber for recycling, which is energy-saving and environmentally friendly. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The existing design of the inner float sealing device is unable to handle the tiny gap between the inner float and the mouth of the oil storage tank, which easily causes the oil to overflow or evaporate from the gap; 2. The existing design of the inner float sealing device is unable to close the exhaust pipe in time when the oil is full, which causes external impurities to easily enter from the exhaust pipe and contaminate the oil.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1 to 5 The utility model provides a technical solution: an inner floating plate sealing device, comprising an oil storage barrel 1, a barrel mouth component 2 is welded and installed on the top of the oil storage barrel 1, and an inner floating plate component 3 is attached to the inner wall of the oil storage barrel 1.
[0023] The inner floating plate assembly 3 includes a conical floating plate 301, a sealing ring 302 is sleeved on one side of the surface of the conical floating plate 301, an exhaust pipe 303 passes through the middle of the surface of the conical floating plate 301, a one-way valve plate 304 is movably connected to one end of the inner wall of the exhaust pipe 303, and four slide grooves 305 are provided at the other end of the inner wall of the exhaust pipe 303, a slide rod 306 is fitted on the inner wall of the slide groove 305, and a floating valve 307 is welded and installed on the bottom of the slide rod 306.
[0024] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the barrel mouth assembly 2 includes a ring cover 201, an inner ring baffle 202 is welded to one side of the bottom of the ring cover 201, a sealing spring 203 is welded to the bottom of the ring cover 201, an inner cone ring 204 is welded to one end of the bottom of the sealing spring 203, the distance between the inner wall of the oil storage barrel 1 and the inner ring baffle 202 is consistent with the ring diameter of the inner cone ring 204, and the inner ring baffle 202 and the ring cover 201 form an integrated structure, this structure can enter the gap between the oil storage barrel 1 and the inner ring baffle 202 after the inner cone ring 204 is squeezed, and fill the gap to ensure the sealing effect.
[0025] In this embodiment, Figure 2 and Figure 3 As shown, the inner cone ring 204 forms an elastic structure with the ring cover 201 through the sealing spring 203. This structure can help the inner cone ring 204 to have space to move upward after being squeezed by the conical floating plate 301 from the bottom, so as to form a closed sealing structure.
[0026] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the one-way valve plate 304 is set to open in one direction, and the exhaust pipe 303 and the conical floating plate 301 form an integrated structure. This structure can automatically close the one-way valve plate 304 when the gas inside the oil storage barrel 1 is no longer discharged, thereby isolating the oil storage barrel 1 from the external environment.
[0027] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the floating valve 307 forms a sliding structure through the sliding rod 306, the sliding groove 305 and the inner wall of the exhaust pipe 303. When the oil inside the oil storage barrel 1 is almost full, this structure can push the floating valve 307 upward through buoyancy, and slide on the inner wall of the exhaust pipe 303 through the sliding rod 306 and the sliding groove 305, and finally block and close the bottom of the exhaust pipe 303.
[0028] In this embodiment, Figure 2 and Figure 3 As shown, the shape of the upper outer wall of the conical floating plate 301 is consistent with the shape of the inner wall of the inner cone ring 204, and the conical floating plate 301 and the inner wall of the oil storage barrel 1 form a split structure. When the internal oil of the oil storage barrel 1 is injected, this structure can make the conical floating plate 301 float upward continuously until it hits the inner cone ring 204, forming a tightly fitted sealing device.
[0029] The use method and advantages of the utility model: When the inner floating disc sealing device is used, the working process is as follows:
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, oil is poured into the oil storage barrel 1 from the top, and the buoyancy of the oil will float the inner float assembly 3 to the top layer of the oil. When the oil injection is nearly completed, the oil pushes the inner float assembly 3 to the bottom of the inner cone ring 204, and the surface of the conical float 301 fits with the inner wall of the inner cone ring 204. The buoyancy of the oil squeezes the sealing spring 203 at the top of the inner cone ring 204, so that the inner cone ring 204 moves up along the gap formed by the inner ring baffle 202 and the inner wall of the oil storage barrel 1, until the top of the sealing ring 302 fits with the bottom of the inner cone ring 204, so that there is no gap between the inner float assembly 3 and the barrel mouth assembly 2. As the oil is continuously filled, the floating valve 307 continuously floats up through the action of the slide rod 306 and the slide groove 305. When the oil is not full, the air in the oil storage barrel 1 can be squeezed into the exhaust pipe 303 and then discharged through the one-way valve plate 304. When the oil is full, the floating valve 307 is pushed into the inner wall of the exhaust pipe 303, blocking and sealing the inner wall of the exhaust pipe 303, so that the oil cannot be discharged from the exhaust pipe 303. At the same time, since no gas is discharged from the exhaust pipe 303, the one-way valve plate 304 is automatically closed, preventing external impurities from entering the interior of the oil storage barrel 1 through the exhaust pipe 303, thereby ensuring that the oil quality is not contaminated.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
