Description

A diesel storage device with good sealing performance and convenient access

Technical Field

The invention relates to the technical field of diesel storage devices, and in particular to a diesel storage device with good airtightness and convenient access.

Background Art

As an important industrial fuel, the safety and convenience of diesel storage and use have always attracted much attention. At present, there are special diesel storage devices on the market for storing diesel, which are designed to ensure the safe, stable and efficient storage of diesel. These devices are usually designed with a tight sealing structure to prevent diesel from volatilizing, leaking or being contaminated by the outside. They are also usually equipped with various safety features, such as explosion-proof, fire-proof and anti-leakage measures to ensure personnel safety and environmental protection during storage and retrieval. There are some problems with traditional diesel storage methods, such as poor airtightness, which can easily lead to diesel volatilization and environmental pollution; inconvenient access, and unable to quickly and accurately meet the use needs; at the same time, it has high requirements for the storage environment and is difficult to adapt to various climatic conditions.

Patent No. CN 217647084 U discloses a biodiesel storage device with good airtightness and convenient access, including a biodiesel storage device and a motor, wherein the biodiesel storage device includes a tank body, a storage bin is provided inside the tank body, an oil filling port is provided at the top of the tank body, a sealing cover is provided inside the oil filling port, a gear is provided inside the sealing cover, a plurality of groups of measuring cups are placed inside the support frame, and a cleaning mechanism is installed on the surface of the tank body. The utility model can ensure a good sealing environment, so that users can proportion the biodiesel usage in advance, so that users can use different amounts of biodiesel, and users can use biodiesel in batches, and can create a low temperature environment for the biodiesel in the storage bin, reduce the impact of the external temperature on the biodiesel, and can easily clean the used measuring cups.

Since diesel itself may contain trace amounts of water and may absorb external water during storage due to factors such as environmental humidity and temperature changes, and the density of water is greater than that of diesel, it will inevitably accumulate a certain amount of water and impurities at the bottom of the storage tank during long-term storage. For the diesel storage device of the utility model, due to its relatively simple structural design, no special oil-water separation structure is set. When taking diesel, if the operator is careless or fails to make an accurate judgment, the diesel containing water and impurities at the bottom is introduced into the device. These water and impurities may have an adverse effect on the normal operation of the equipment and even cause damage to the equipment. In addition, during the long-term storage of diesel, a certain amount of impurities may still gradually accumulate on the inner wall of the tank. These impurities may include precipitates produced by diesel oxidation, metal corrosion products, etc. As time goes by, these impurities will continue to accumulate, which not only affects the cleanliness of the storage tank, but may also cause pollution to the diesel stored subsequently. In response to the above problems, the present invention document proposes a diesel storage device with good airtightness and easy access.

Summary of the invention

The purpose of the present invention is to solve the shortcomings of the prior art and to propose a diesel storage device that can effectively avoid the problem of moisture and impurities accumulated at the bottom, avoid affecting the normal operation of subsequent equipment, and has high safety, good sealing and easy access.

In order to achieve the above object, the present invention adopts the following technical solutions:

The oil-water separation structure includes at least two limit rods fixedly connected to the inside of the storage barrel, the outer wall of the limit rod is slidably connected to a mounting frame, and a buoyancy ball is installed on the top of the mounting frame, all of the mounting frames are commonly fixedly connected to the same collecting cover, the bottom of the collecting cover is connected to a conduit, the discharge structure includes a water pump body installed at the bottom of the storage barrel, the water outlet of the water pump body is connected to a drain pipe, and the water inlet of the water pump body is connected to an end of the conduit away from the collecting cover.

Preferably, a discharge valve is provided at the bottom of the storage barrel, and the shape of the bottom of the storage barrel is set to be a truncated cone, and a feed cylinder is provided at the top of the storage barrel.

Preferably, the driving structure includes a motor installed on the top of the storage barrel, a winding frame is fixedly connected to the output end of the motor, and the conduit is folded in half and wound around the outer wall of the winding frame, and the cross-sectional shape of the winding frame is set to be an I-shape.

Preferably, the cleaning structure comprises a rotating frame fixedly connected to the outer wall of the motor output end, and at least one cleaning scraper is fixedly connected to the rotating frame, and the cleaning scraper fits with the inside of the storage barrel.

Preferably, the winding frame, the rotating frame and the cleaning scraper are all located inside the storage barrel, and the rotating frame is located on the top of the winding frame.

Preferably, the limiting structure includes a limiting frame fixedly connected to the inside of the storage barrel, and the limiting frame is shaped as an L-shape, and a plurality of first limiting rings are fixedly connected to the side of the limiting frame, and the folded conduit passes through all the first limiting rings.

Preferably, a second limiting ring is fixedly connected to the bottom of the storage barrel, and one end of the conduit close to the collecting cover passes through the second limiting ring.

Preferably, the protective structure includes a first filter screen fixedly connected to the top of the collecting cover, and a connecting plate fixedly connected to the tops of all the limiting rods.

Preferably, a second filter screen is fixedly connected inside the connection disk, and a diameter of the connection disk is larger than a diameter of the first filter screen.

Compared with the prior art, the present invention provides a diesel storage device with good sealing performance and convenient access, which has the following beneficial effects:

1. The diesel storage device with good airtightness and easy access is provided with an oil-water separation structure and a discharge structure. During the long-term storage of diesel, the water contained in the diesel will be separated and collected at the bottom of the storage barrel, and the diesel will be collected at the top, resulting in stratification. When the diesel stored in the storage barrel is large, the collection cover can only be located in the middle of the storage barrel under the limiting action of the connecting plate. When the diesel stored in the storage barrel is small, the collection cover can always be located near the diesel liquid surface under the buoyancy of the buoyancy ball, thereby ensuring that after the diesel stored in the storage barrel is stratified, the pure diesel at the top still enters the conduit through the collection cover, and is then discharged through the water pump body and the drain pipe, thereby effectively avoiding the problem of introducing the water and impurities accumulated at the bottom, avoiding affecting the normal operation of subsequent equipment, and having high safety. The diesel in the storage barrel is discharged through the water pump body, and there is no need for the operator to open the discharge valve or the feed barrel, thereby ensuring the sealing of the storage barrel.

2. The diesel storage device with good sealing performance and convenient access is provided with a driving structure and a cleaning structure. Since a small amount of solid impurities may be mixed inside the diesel, the impurities will still accumulate on the inner wall of the storage barrel during the long-term use of the storage barrel. When the motor is working, it can drive the rotating frame to rotate. The rotating frame scrapes the inner wall of the storage barrel through the cleaning scraper, thereby cleaning the impurities adhering to the inner wall of the storage barrel, avoiding the impurities from contaminating the diesel subsequently stored in the storage barrel, thereby ensuring the quality of the diesel discharged after the storage by the device, and when the motor drives the winding frame to rotate, it can wind the conduit, thereby preventing the conduits accumulated at the bottom of the storage barrel from obstructing the collecting cover when the capacity of the diesel stored in the storage barrel is reduced and the height of the collecting cover is reduced, thereby ensuring that when the capacity of the diesel stored in the storage barrel is small, the collecting cover can still collect the diesel normally and complete the access process.

3. The diesel storage device with good sealing performance and easy access is provided with a limit structure and a second limit ring. The limit frame, the first limit ring and the second limit ring cooperate with each other, so as to play a certain limiting role on the conduit, ensuring that the position of the conduit inside the storage barrel is guaranteed to be within a certain range, thereby avoiding the conduit from affecting the movement of the collecting cover and the cleaning scraper, and ensuring that the device can work normally.

4. The diesel storage device with good sealing performance and easy access is provided with a protective structure. When a large amount of diesel is stored in the storage barrel, the buoyancy of the buoyancy ball allows the first filter to fit tightly with the connecting plate. As the capacity of the diesel stored in the storage barrel decreases, the buoyancy of the buoyancy ball allows the first filter to always be located above the liquid level, so that the first filter and the second filter can filter the diesel entering the collection cover and remove impurities mixed in the diesel, thereby providing certain protection for equipment that uses the diesel subsequently.

Embodiment 1: Referring to Figures 1-5, a diesel storage device with good sealing performance and convenient access includes a storage barrel 1, an oil-water separation structure 2 is installed inside the storage barrel 1, and a discharge structure 3 that cooperates with the oil-water separation structure 2 is arranged on the storage barrel 1, a driving structure 4 is arranged on the top of the storage barrel 1, and a cleaning structure 5 for cleaning the inside of the storage barrel 1 is installed on the driving structure 4, a limiting structure 6 is arranged inside the storage barrel 1, and a protective structure 7 is installed on the oil-water separation structure 2;

The oil-water separation structure 2 includes at least two limit rods 201 fixedly connected to the inside of the storage barrel 1, the outer wall of the limit rod 201 is slidably connected to a mounting frame 202, and a buoyancy ball 203 is installed on the top of the mounting frame 202, all the mounting frames 202 are commonly fixedly connected to the same collecting cover 204, and the bottom of the collecting cover 204 is connected to a conduit 205, and the discharge structure 3 includes a water pump body 301 installed at the bottom of the storage barrel 1, the water outlet of the water pump body 301 is connected to a drain pipe 302, and the water inlet of the water pump body 301 is connected to the end of the conduit 205 away from the collecting cover 204.

In the present invention, a discharge valve 101 is provided at the bottom of the storage barrel 1, and the shape of the bottom of the storage barrel 1 is set to be a cone, and a feed tube 102 is provided at the top of the storage barrel 1. By setting the discharge valve 101, the moisture inside the storage barrel 1 is guaranteed, and the impurities cleaned by the cleaning scraper 502 inside the storage barrel 1 can be discharged normally, avoiding affecting the quality of the subsequent stored diesel.

In the present invention, the driving structure 4 includes a motor 401 installed on the top of the storage barrel 1, and a winding frame 402 is fixedly connected to the output end of the motor 401, and the conduit 205 is folded in half and wound around the outer wall of the winding frame 402. The cross-sectional shape of the winding frame 402 is set to an I-shape. By setting the motor 401 and the winding frame 402, the motor 401 drives the winding frame 402 to rotate, and the conduit 205 can be wound. When the capacity of diesel stored in the storage barrel 1 is reduced and the height of the collecting cover 204 is reduced, the conduit 205 accumulated at the bottom of the storage barrel 1 causes obstruction to the collecting cover 204, thereby ensuring that when the capacity of diesel stored in the storage barrel 1 is small, the collecting cover 204 can still collect the diesel normally and complete the emission treatment.

In the present invention, the cleaning structure 5 includes a rotating frame 501 fixedly connected to the outer wall of the output end of the motor 401, and at least one cleaning scraper 502 is fixedly connected to the rotating frame 501, and the cleaning scraper 502 is in contact with the inside of the storage barrel 1. The winding frame 402, the rotating frame 501 and the cleaning scraper 502 are all located inside the storage barrel 1, and the rotating frame 501 is located on the top of the winding frame 402. By arranging the rotating frame 501 and the cleaning scraper 502, since a small amount of solid impurities may be mixed inside the diesel, during the long-term use of the storage barrel 1, the impurities will still accumulate on the inner wall of the storage barrel 1. When the motor 401 is working, it can drive the rotating frame 501 to rotate, and the rotating frame 501 scrapes the inner wall of the storage barrel 1 through the cleaning scraper 502, thereby cleaning the impurities adhered to the inner wall of the storage barrel 1, avoiding the impurities from polluting the diesel subsequently stored in the storage barrel 1, and ensuring the quality of the diesel discharged after the storage of the device.

Embodiment 2: Referring to FIGS. 1-9 , a diesel storage device with good sealing performance and convenient access includes a storage barrel 1, an oil-water separation structure 2 is installed inside the storage barrel 1, and a discharge structure 3 that cooperates with the oil-water separation structure 2 is arranged on the storage barrel 1, a driving structure 4 is arranged on the top of the storage barrel 1, and a cleaning structure 5 for cleaning the inside of the storage barrel 1 is installed on the driving structure 4, a limiting structure 6 is arranged inside the storage barrel 1, and a protective structure 7 is installed on the oil-water separation structure 2;

The oil-water separation structure 2 includes at least two limit rods 201 fixedly connected to the inside of the storage barrel 1, the outer wall of the limit rod 201 is slidably connected to a mounting frame 202, and a buoyancy ball 203 is installed on the top of the mounting frame 202, all the mounting frames 202 are commonly fixedly connected to the same collecting cover 204, and the bottom of the collecting cover 204 is connected to a conduit 205, and the discharge structure 3 includes a water pump body 301 installed at the bottom of the storage barrel 1, the water outlet of the water pump body 301 is connected to a drain pipe 302, and the water inlet of the water pump body 301 is connected to the end of the conduit 205 away from the collecting cover 204.

In the present invention, a discharge valve 101 is provided at the bottom of the storage barrel 1, and the shape of the bottom of the storage barrel 1 is set to be a cone, and a feed tube 102 is provided at the top of the storage barrel 1. By setting the discharge valve 101, the moisture inside the storage barrel 1 is guaranteed, and the impurities cleaned by the cleaning scraper 502 inside the storage barrel 1 can be discharged normally, avoiding affecting the quality of the subsequent stored diesel.

In the present invention, the driving structure 4 includes a motor 401 installed on the top of the storage barrel 1, and a winding frame 402 is fixedly connected to the output end of the motor 401, and the conduit 205 is folded in half and wound around the outer wall of the winding frame 402. The cross-sectional shape of the winding frame 402 is set to an I-shape. By setting the motor 401 and the winding frame 402, the motor 401 drives the winding frame 402 to rotate, and the conduit 205 can be wound. When the capacity of diesel stored in the storage barrel 1 is reduced and the height of the collecting cover 204 is reduced, the conduit 205 accumulated at the bottom of the storage barrel 1 causes obstruction to the collecting cover 204, thereby ensuring that when the capacity of diesel stored in the storage barrel 1 is small, the collecting cover 204 can still collect the diesel normally and complete the emission treatment.

In the present invention, the cleaning structure 5 includes a rotating frame 501 fixedly connected to the outer wall of the output end of the motor 401, and at least one cleaning scraper 502 is fixedly connected to the rotating frame 501, and the cleaning scraper 502 is in contact with the inside of the storage barrel 1. The winding frame 402, the rotating frame 501 and the cleaning scraper 502 are all located inside the storage barrel 1, and the rotating frame 501 is located on the top of the winding frame 402. By arranging the rotating frame 501 and the cleaning scraper 502, since a small amount of solid impurities may be mixed inside the diesel, during the long-term use of the storage barrel 1, the impurities will still accumulate on the inner wall of the storage barrel 1. When the motor 401 is working, it can drive the rotating frame 501 to rotate, and the rotating frame 501 scrapes the inner wall of the storage barrel 1 through the cleaning scraper 502, thereby cleaning the impurities adhered to the inner wall of the storage barrel 1, avoiding the impurities from polluting the diesel subsequently stored in the storage barrel 1, and ensuring the quality of the diesel discharged after the storage of the device.

In the present invention, the limiting structure 6 includes a limiting frame 601 fixedly connected to the inside of the storage barrel 1, and the shape of the limiting frame 601 is set to be L-shaped. A plurality of first limiting rings 602 are fixedly connected to the side of the limiting frame 601. The folded conduit 205 passes through all the first limiting rings 602. A second limiting ring 8 is fixedly connected to the bottom of the storage barrel 1. One end of the conduit 205 close to the collecting cover 204 passes through the second limiting ring 8. By setting the limiting structure 6 and the second limiting ring 8, the limiting frame 601, the first limiting ring 602 and the second limiting ring 8 cooperate with each other, thereby playing a certain limiting role on the conduit 205, ensuring that the position of the conduit 205 inside the storage barrel 1 is guaranteed to be within a certain range, thereby avoiding the conduit 205 from affecting the movement of the collecting cover 204 and the cleaning scraper 502, and ensuring that the device can work normally.

In the present invention, the protective structure 7 includes a first filter screen 701 fixedly connected to the top of the collecting cover 204, and a connecting plate 702 fixedly connected to the top of all the limit rods 201. A second filter screen 703 is fixedly connected inside the connecting plate 702, and the diameter of the connecting plate 702 is larger than the diameter of the first filter screen 701. By arranging the first filter screen 701, the connecting plate 702 and the second filter screen 703, when the diesel stored in the storage barrel 1 is large, the buoyancy of the buoyancy ball 203 makes the first filter screen 701 fit tightly with the connecting plate 702. As the capacity of the diesel stored in the storage barrel 1 decreases, the buoyancy of the buoyancy ball 203 makes the first filter screen 701 still always located above the liquid level, so that the first filter screen 701 and the second filter screen 703 can filter the diesel entering the collecting cover 204, remove impurities mixed in the diesel, and provide a certain protection for the equipment that uses the diesel in the future.

Working principle: When diesel is stored for a long time, the water contained in it will be separated and collected at the bottom of the storage barrel 1, and the diesel will be collected at the top, resulting in stratification. When there is a lot of diesel stored in the storage barrel 1, the buoyancy of the buoyancy ball 203 makes the first filter 701 fit tightly with the connecting plate 702. As the capacity of diesel stored in the storage barrel 1 decreases, the buoyancy of the buoyancy ball 203 makes the first filter 701 always remain above the liquid level, so that the first filter 701 and the second filter 703 can filter the diesel entering the collection cover 204 and remove the impurities mixed in the diesel.

The operator opens the water pump body 301, so that the water pump body 301 transfers the pure diesel stored in the storage barrel 1 through the conduit 205 and the collecting cover 204, and then discharges it through the drain pipe 302, thereby completing the diesel removal and placement processing. When the collecting cover 204 is under the buoyancy of the buoyancy ball 203, as the liquid level of the diesel stored in the storage barrel 1 decreases, the motor 401 can work regularly. When the motor 401 drives the winding frame 402 to rotate, the folded conduit 205 is wound, and the motor 401 synchronously drives the cleaning scraper 502 to rotate through the rotating frame 501, so as to clean the impurities adhering to the storage barrel 1. When the diesel stored in the storage barrel 1 is taken out, the operator can open the discharge valve 101, so that the water in the storage barrel 1 and the impurities cleaned by the cleaning scraper 502 can be discharged through the discharge valve 101.

The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
