Description

Technical Field

[0001] This utility model relates to the field of asphalt tank technology, and in particular to a hydraulic breather valve for asphalt storage tanks. Background Technology

[0002] An asphalt tank is a device specifically designed for storing and transporting asphalt. During use, the internal pressure of the gas increases due to the operation or shaking of the device. To ensure safety, the internal pressure needs to be released through a hydraulic breather valve. However, the gas released contains a large amount of oil and gas, which can contaminate the internal parts of the valve body and hinder its operation. Existing cleaning methods generally involve disassembling the device and cleaning it separately, which makes the cleaning process cumbersome and not conducive to the convenient use of the device.

[0003] Therefore, we provide a hydraulic breather valve for asphalt storage tanks. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a hydraulic breather valve for asphalt storage tanks, which achieves the effect of cleaning oil and gas while facilitating the replacement of components.

[0005] In view of this, the present invention provides a hydraulic breather valve for asphalt storage tanks, including a supporting tank body and a hydraulic breather valve body fixedly installed on the upper end of the supporting tank body. A negative pressure valve is fixedly connected to the outside of the hydraulic breather valve body. A limit groove is formed on the outside of the negative pressure valve. An arc-shaped rotating shell is inserted into the limit groove. An arc-shaped support block is fixedly connected inside the arc-shaped rotating shell. An adsorption plate is provided on the inner wall of the arc-shaped support block. A rotating support rod is rotatably connected to the outside of the arc-shaped rotating shell. Fixed support blocks are fixedly connected to both sides of the rotating support rod. The fixed support blocks are fixedly installed outside the negative pressure valve. The arc-shaped rotating shell is located between the two fixed support blocks.

[0006] Preferably, a number of fastening support blocks are fixedly connected to the outside of the adsorption plate, and the number of fastening support blocks are in two groups for operation.

[0007] Preferably, the arc-shaped support block is located between the two sets of fastening support blocks, and the fastening support block and the arc-shaped support block are connected by an outer fastening bolt.

[0008] Preferably, a sealing support ring is provided on each of the two sides of the arc-shaped support block, the sealing support ring is fixedly disposed on the inner wall of the arc-shaped rotating shell, and the sealing support ring is located above the adsorption plate.

[0009] Preferably, a movable handle is fixedly connected to the outer side of the arc-shaped rotating shell, and plug-in blocks are fixedly connected to the lower ends of both sides of the movable handle, with plug-in slots inserted into the plug-in blocks.

[0010] Preferably, the insertion groove is formed on one side of the inner wall of the limiting groove, a sealing ring is provided on one side of the insertion groove, the sealing ring is fixedly disposed on the inner wall of the limiting groove, and the sealing support ring is located in the middle of the sealing ring.

[0011] Preferably, at least two arc-shaped limiting plates are fixedly connected to the inner wall of the negative pressure valve, and the adsorption plate is located between the two arc-shaped limiting plates.

[0012] The beneficial effects of this utility model are as follows: Under the operation of the hydraulic breather valve, it can automatically adjust according to the changes in air pressure inside the support tank, improving the safety and stability of the internal pressure of the support tank during operation. Furthermore, under the operation of the negative pressure valve on one side of the hydraulic breather valve, a negative pressure effect is created within the flow of the hydraulic breather valve, causing the oil and gas in the flowing gas to flow towards the negative pressure valve under the guidance of the negative pressure. This allows for the adsorption of oil and gas in the gas through the adsorption support of the arc-shaped rotating shell inside the negative pressure valve. This ensures the cleanliness of the gas flow and improves the continuous operational stability of the upper components. Simultaneously, the stability of the arc-shaped rotating shell during rotation is ensured by the support of the rotating support rod by two fixed support blocks on the outside of the negative pressure valve. The rotation of the arc-shaped rotating shell and the support and guidance effect of the limiting groove allow for the removal of the adsorption plate, ensuring convenient replacement of the adsorption plate and further improving the stability of the adsorption of oil and gas in the gas flowing out of the arc-shaped support block by the hydraulic breather valve and the negative pressure valve.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0019] A hydraulic breather valve for asphalt storage tanks, such as Figure 1-4 As shown, the device includes a support tank 1 and a hydraulic breather valve body 2 fixedly mounted on the upper end of the support tank 1. A negative pressure valve 3 is fixedly connected to the outside of the hydraulic breather valve body 2. A limit groove 4 is formed on the outside of the negative pressure valve 3, and an arc-shaped rotating shell 10 is inserted into the limit groove 4. An arc-shaped support block 11 is fixedly connected inside the arc-shaped rotating shell 10. An adsorption plate 14 is provided on the inner wall of the arc-shaped support block 11. A rotating support rod 9 is rotatably connected to the outside of the arc-shaped rotating shell 10. Fixed support blocks 8 are fixedly connected to both sides of the rotating support rod 9. The fixed support blocks 8 are fixedly mounted on the outside of the negative pressure valve 3. The arc-shaped rotating shell 10 is located between the two fixed support blocks 8. When the device is running, the hydraulic breather valve body 2 can automatically adjust according to the changes in air pressure inside the support tank 1, improving the safety and stability of the internal pressure of the support tank 1 during operation. Furthermore, the hydraulic breather valve body 2 can automatically adjust according to the changes in air pressure inside the support tank 1. When the negative pressure valve 3 is in operation, it can create a negative pressure effect from the flow inside the hydraulic breather valve body 2, causing the oil and gas in the flowing gas to flow towards the negative pressure valve 3 under the guidance of the negative pressure. This allows the oil and gas in the gas to be adsorbed by the arc-shaped rotating shell 10 inside the negative pressure valve 3, ensuring the cleanliness of the gas flow and improving the continuous operation stability of the upper components. At the same time, the two fixed support blocks 8 on the outside of the negative pressure valve 3 support the rotating support rod 9, ensuring the stability of the arc-shaped rotating shell 10 when it rotates. This allows the adsorption plate 14 to be removed by rotating the arc-shaped rotating shell 10 and under the support and guidance of the limiting groove 4, ensuring the convenience of replacing the adsorption plate 14. This further improves the stability of the adsorption of oil and gas in the gas flowing out of the arc-shaped support block 11 by the hydraulic breather valve body 2 and the negative pressure valve 3.

[0020] like Figure 1-4 As shown, several fastening support blocks 12 are fixedly connected to the outside of the adsorption plate 14, and the fastening support blocks 12 are in two groups. The arc-shaped support block 11 is located between the two groups of fastening support blocks 12. The fastening support blocks 12 and the arc-shaped support block 11 are connected by the outer fastening bolts. With the support of the arc-shaped support block 11 and the fastening support blocks 12 on both sides, and with the effect of fastening the two or more fastening support blocks 12 and the arc-shaped support block 11 at the same time by the outer fastening bolts, the position of the adsorption plate 14 and the arc-shaped support block 11 is fastened, thereby ensuring the stability of the adsorption plate 14 when it is used in a fixed position, and the reliability of the adsorption plate 14 when it is moved.

[0021] like Figure 1-4 As shown, sealing support rings 13 are provided on both sides of the arc-shaped support block 11. The sealing support rings 13 are fixedly installed on the inner wall of the arc-shaped rotating shell 10 and are located above the adsorption plate 14. By the sealing support rings 13 around the inner wall of the arc-shaped rotating shell 10 and the components below, the outer side of the adsorption plate 14 is sealed, thereby ensuring the sealing stability of the device during operation. Example 2

[0022] A hydraulic breather valve for asphalt storage tanks, such as Figure 1-4 As shown, a movable handle 16 is fixedly connected to the outer side of the arc-shaped rotating shell 10. Insertion blocks 15 are fixedly connected to the lower ends of both sides of the movable handle 16. Insertion blocks 15 are inserted into insertion grooves 6, which are located on one side of the inner wall of the limiting groove 4. A sealing ring 5 is provided on one side of the insertion groove 6 and is fixedly installed on the inner wall of the limiting groove 4. A sealing support ring 13 is located in the middle of the sealing ring 5. The arc-shaped rotating shell 10 can be rotated and moved out and installed under the support of the movable handle 16. Furthermore, the insertion of the insertion groove 6 and the sealing ring 5 ensures directional stability when the arc-shaped rotating shell 10 is placed. The sealing ring 5 and the sealing support ring 13 around the inner wall of the limiting groove 4 are pressed and tightened, achieving a stable seal between the arc-shaped rotating shell 10 and the limiting groove 4, thus ensuring stable and efficient gas flow within the device.

[0023] like Figure 1-4 As shown, at least two arc-shaped limiting plates 7 are fixedly connected to the inner wall of the negative pressure valve 3. The adsorption plate 14 is located between the two arc-shaped limiting plates 7. Under the support and limitation of the two arc-shaped limiting plates 7 on the inner wall of the negative pressure valve 3, the stability and efficiency of the adsorption plate 14 when it is placed are ensured, thereby improving the positional stability of the device when the adsorption plate 14 is placed and ensuring the stable support effect of the adsorption plate 14 when the gas flows.

[0024] Working principle: The hydraulic breather valve 2 automatically adjusts to changes in internal pressure within the support tank 1, improving the safety and stability of the internal pressure during operation. Furthermore, the operation of the negative pressure valve 3 on one side of the hydraulic breather valve 2 creates a negative pressure effect within the flow path, causing oil and gas in the circulating gas to flow towards the negative pressure valve 3. This oil and gas are then adsorbed by the arc-shaped rotating shell 10 inside the negative pressure valve 3, ensuring the gas... The cleanliness during flow improves the continuous operational stability of the upper components. At the same time, the support of the rotating support rod 9 by the two fixed support blocks 8 on the outside of the negative pressure valve 3 ensures the stability of the outer arc-shaped rotating shell 10 during rotation. Thus, by rotating the arc-shaped rotating shell 10 and under the support and guidance of the limiting groove 4, the adsorption plate 14 can be removed, ensuring the convenience of replacing the adsorption plate 14. This further improves the stability of oil and gas adsorption in the gas flowing out of the arc-shaped support block 11 by the hydraulic breather valve body 2 and the negative pressure valve 3.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
