Description

Technical Field

[0001] This utility model relates to the technical field of reclaimed rubber production equipment, and in particular to a sealing structure for a reclaimed rubber desulfurization tank that is resistant to high-temperature oxidation. Background Technology

[0002] In the process of reclaimed rubber production, the sealing performance of desulfurization tanks is crucial. Traditional desulfurization tank sealing structures are prone to sealing failure when facing high-temperature oxidizing environments, leading to exhaust gas leakage, which not only pollutes the environment but also affects product quality and production efficiency.

[0003] For example, some sealing materials lose elasticity at high temperatures and cannot effectively fill gaps, causing harmful gases to escape; some sealing structures are poorly designed and are easily damaged during frequent loading and unloading, increasing equipment maintenance costs and downtime; therefore, developing a high-temperature oxidation resistant and reliable sealing structure for desulfurization tanks made of recycled rubber is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor sealing effect and easy damage of traditional desulfurization tank sealing structures in high-temperature oxidizing environments, and to propose a high-temperature oxidation-resistant reclaimed rubber desulfurization tank sealing structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature oxidation-resistant desulfurization tank sealing structure for recycled rubber includes a cylindrical fixed tank interface and a movable tank. The movable tank is detachably installed at one end of the fixed tank interface. A sealing seat is coaxially fixedly connected to the lower end of the movable tank. A trapezoidal annular groove is provided in the inner cavity of the top of the fixed tank interface. The inner cavity of the trapezoidal annular groove and the lower surface of the sealing seat fit together.

[0007] The top of the trapezoidal annular groove is connected to a sealing groove with an enlarged diameter. A sealing gasket is fitted onto the inner wall of the sealing groove, and the upper surface of the sealing seat and the lower surface of the sealing gasket are in contact with each other.

[0008] The movable tank and the sealing seat are provided with a second annular inner cavity that is interconnected. The top two sides of the second annular inner cavity are respectively connected to a first connecting pipe and a second connecting pipe. The vertical cross-section of the second annular inner cavity is L-shaped. The second annular inner cavity is located between the sealing seat and the interface cavity of the fixed tank. The inlet of the first connecting pipe is connected to a water source.

[0009] Preferably, the outer periphery of the movable tank is movably connected with an annular fastener. The outer wall of the annular fastener is detachably installed on the fixed tank interface. The bottom of the vertical cross-section of the annular fastener is convex arc-shaped and is assembled above the sealing groove and sealing seat. The upper end of the sealing gasket is fitted and installed on the convex arc-shaped surface of the annular fastener.

[0010] Preferably, a first annular inner cavity is provided at the top of the fixed tank interface near the sealing seat. A water inlet pipe is fixedly connected to the lower side of one side of the first annular inner cavity, and a water outlet pipe is fixedly connected to the upper side of the other side of the first annular inner cavity. The water source is connected to the inlet of the water inlet pipe.

[0011] Preferably, a plurality of evenly arranged straight rollers are fixedly installed on the outer ring of the annular fastener.

[0012] Preferably, the sealing groove is coaxially connected to an internally threaded groove with an enlarged diameter above it, and the annular fastener has an external thread on its outer ring in the middle. The annular fastener is installed on the fixed tank interface through the internally threaded groove and the externally threaded groove.

[0013] Preferably, the sealing gasket is made of silicone rubber material that is resistant to high temperature and oxidation and has good elasticity.

[0014] Compared with the prior art, this utility model provides a high-temperature oxidation-resistant sealing structure for a desulfurization tank made of recycled rubber, which has the following advantages:

[0015] 1. The high-temperature oxidation-resistant reclaimed rubber desulfurization tank sealing structure allows tap water or circulating water to flow through the first and second annular inner cavities. Utilizing the characteristic that water's boiling point does not exceed 100 degrees Celsius, a thermal barrier is formed between the sealing gasket and the interface of the fixed tank body and the high temperature of the moving tank inner cavity. Through the principles of heat conduction and heat convection, heat is transferred to and carried away by the circulating water, essentially ensuring that the temperature of the sealing gasket does not exceed 100 degrees Celsius. This significantly improves the stability of the sealing structure in high-temperature environments and extends the service life of the sealing gasket.

[0016] 2. The sealing structure of this high-temperature oxidation-resistant reclaimed rubber desulfurization tank, through the precise matching of the sealing seat and the trapezoidal annular groove, coupled with the use of a high-temperature resistant, oxidation-resistant, and highly elastic silicone rubber sealing gasket, can tightly fit the sealing surface, effectively preventing exhaust gas leakage, ensuring the sealing performance of the desulfurization tank, and providing a stable environment for reclaimed rubber desulfurization.

[0017] 3. The annular fasteners in the sealing structure of the high-temperature oxidation-resistant recycled rubber desulfurization tank are threaded and connected to the internal thread groove of the fixed tank interface through the external thread, which makes the installation stable and easy to disassemble. The straight roller on the outer ring of the annular fastener makes it easy for operators to rotate the annular fastener, reducing labor intensity, improving work efficiency, and making equipment maintenance and repair easier.

[0018] 4. The high-temperature oxidation-resistant reclaimed rubber desulfurization tank sealing structure, with ring fasteners made of high-strength alloy steel, has good compressive strength and wear resistance. It can not only apply stable pressure to the sealing components to enhance the sealing effect, but also protect the sealing components from damage by external factors to a certain extent, enhance the stability of the entire sealing structure, and reduce the sealing failure caused by external forces and other factors.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Reference Figures 1-4A high-temperature oxidation-resistant reclaimed rubber desulfurization tank sealing structure includes a cylindrical fixed tank interface 1 and a movable tank 2. The fixed tank interface 1 is the connection port of the fixed part of the desulfurization tank, which is usually welded to the main body of the desulfurization tank or fixedly connected by other reliable means. The movable tank 2 is detachably installed at one end of the fixed tank interface 1 to facilitate equipment inspection and maintenance. The movable tank 2 is a part that can be detached from the fixed tank interface 1, and is generally used as the tank cover or an openable side of the tank to facilitate material loading and unloading operations. A sealing seat 15 is coaxially fixedly connected to the lower end of the movable tank 2. A trapezoidal annular groove 9 is provided in the inner cavity of the top of the fixed tank interface 1. The inner cavity of the trapezoidal annular groove 9 and the lower surface of the sealing seat 15 fit together. This structural design allows the sealing seat 15 to be accurately installed in the fixed tank interface 1, initially forming a sealing structure and providing a foundation for subsequent sealing measures.

[0027] refer to Figure 2 The top of the trapezoidal annular groove 9 is connected to a sealing groove 10 with an enlarged diameter. A sealing gasket 12 is fitted onto the inner wall of the sealing groove 10. The upper surface of the sealing seat 15 and the lower surface of the sealing gasket 12 are fitted together. The sealing gasket 12 is made of silicone rubber material that is resistant to high temperature and oxidation and has good elasticity. In a high-temperature oxidation environment, the silicone rubber material can maintain good elasticity and sealing performance, effectively filling the gap between the sealing seat 15 and the fixed tank interface 1 to prevent exhaust gas leakage.

[0028] refer to Figure 3 and Figure 4 The movable tank 2 and the sealing seat 15 are provided with a second annular inner cavity 14 that is interconnected. The top two sides of the second annular inner cavity 14 are respectively connected to a first connecting pipe 5 and a second connecting pipe 6. The vertical cross-section of the second annular inner cavity 14 is L-shaped and is located between the sealing seat 15 and the inner cavity of the fixed tank interface 1. The inlet of the first connecting pipe 5 is connected to a water source. By introducing cooling water into the second annular inner cavity 14, the temperature of the sealing structure can be reduced, the impact of high temperature on the sealing material can be reduced, and the high temperature resistance of the sealing structure can be further improved. At the same time, the top of the fixed tank interface 1 is provided near the sealing seat 15 with a first annular inner cavity 13. The lower side of one side of the first annular inner cavity 13 is fixedly connected to a water inlet pipe 7, and the upper side of the other side is fixedly connected to a water outlet pipe 8. The water source and the inlet of the water inlet pipe 7 are connected to form another cooling circulation system. The dual cooling ensures the stability of the sealing structure in a high temperature environment.

[0029] refer to Figure 3 and Figure 4The movable tank body 2 is movably connected to an annular fastener 3. The annular fastener 3 is made of high-strength alloy steel and has good pressure resistance and wear resistance. The outer wall of the annular fastener 3 is detachably installed on the fixed tank body interface 1. Its vertical cross-section bottom is convex arc-shaped and is assembled above the sealing groove 10 and the sealing seat 15. The upper end of the sealing gasket 12 is fitted and installed on the convex arc-shaped surface of the annular fastener 3. The annular fastener 3 can not only apply pressure to the sealing seat 15 and the sealing gasket 12 to enhance the sealing effect, but also protect the sealing assembly to a certain extent from damage. Damage caused by external factors; in addition, several evenly arranged straight rollers 4 are fixedly installed on the outer ring of the annular fastener 3, mainly used to assist manual rotation of the annular fastener 3, making it convenient for operators to install and disassemble, and improving work efficiency. The upper part of the sealing groove 10 is coaxially connected to an internal thread groove 11 with an enlarged diameter. The outer ring of the middle part of the annular fastener 3 is provided with an external thread 16. The annular fastener 3 is threaded onto the fixed tank interface 1 through the internal thread groove 11 and the external thread 16. This threaded connection method makes the installation more stable and facilitates disassembly and adjustment.

[0030] The installation steps of this utility model for the high-temperature oxidation-resistant reclaimed rubber desulfurization tank sealing structure are as follows:

[0031] Before installation, carefully clean the fixed tank interface 1, the movable tank 2 and the surface of each component to ensure that there are no impurities, oil stains, etc., so as to avoid affecting the sealing effect and connection stability.

[0032] Accurately embed the sealing gasket 12 into the sealing groove 10, gently press it to make it fit tightly against the inner wall of the sealing groove 10, check for wrinkles or misalignment, and ensure the installation quality of the sealing gasket 12.

[0033] Align the sealing seat 15 of the movable tank 2 with the trapezoidal annular groove 9 of the fixed tank interface 1, and slowly and steadily insert the movable tank 2 until the sealing seat 15 and the trapezoidal annular groove 9 are completely matched, thus completing the initial assembly of the sealing structure.

[0034] The annular fastener 3 is threaded to the internal thread groove 11 on the fixed tank interface 1 via the external thread 16. During the connection process, the operator can use the straight roller 4 to assist in rotating the annular fastener 3 and slowly tighten it in a clockwise direction until the sealing gasket 12 is tightly pressed between the sealing seat 15 and the annular fastener 3 to achieve a good sealing state. During this period, the installation can be ensured by observation or a simple sealing test.

[0035] Connect the first connecting pipe 5 and the second connecting pipe 6 to the water source, such as a tap water pipe or a circulating water system, to ensure that the water circuit connection is firm and there is no risk of leakage. At the same time, connect the inlet pipe 7 and the outlet pipe 8 so that the cooling circulation system of the first annular inner cavity 13 can also operate normally. Open the water valve to check whether the water flow is smooth and whether each connection is well sealed.

[0036] In this embodiment, the high-temperature oxidation-resistant reclaimed rubber desulfurization tank sealing structure is used as follows:

[0037] Before the desulfurization tank for recycled rubber is put into use, the water valve is opened first, and tap water or circulating water is introduced into the second annular inner cavity 14 and the first annular inner cavity 13 through the first connecting pipe 5 and the water inlet pipe 7 respectively. The water flow and pressure are adjusted to ensure that the cooling system works normally and effectively reduce the temperature of the sealing structure.

[0038] During normal production, closely monitor the operation of the cooling system and regularly check parameters such as water temperature and flow to ensure stable cooling performance. At the same time, periodically check the sealing structure for signs of leakage, such as by applying soapy water to the joints and observing for bubbles. If any abnormalities are found, immediately stop the machine for repair.

[0039] When the desulfurization tank needs to be inspected or maintained, first turn off the cooling water source, open the drain valve, and drain the cooling water in the second annular inner cavity 14 and the first annular inner cavity 13. Then, with the help of the straight roller 4, rotate the annular fastener 3 in the opposite direction to separate it from the fixed tank interface 1 in the counterclockwise direction. Carefully remove the movable tank 2 and carry out subsequent maintenance operations. Take care to avoid damaging any components during the operation.

[0040] 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.
