Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a novel sealing structure for an air compressor waste heat recovery machine. Background Technology

[0002] Air compression is the process of increasing the pressure and density of air using a compression device, namely a compressor. A compressor increases the pressure of a gas while reducing its volume. This allows air to be compressed into a smaller space, increasing its ease of storage and transportation.

[0003] Air compressors generate a significant amount of heat during operation, primarily due to the mechanical motion within the compressor and the friction and compression heat produced during gas compression. Waste heat recovery machines use heat exchangers or other technologies to capture this waste heat from the cooling air discharged from the air compressor and transfer it to water or other fluids, thereby converting the waste heat into usable thermal energy or hot water.

[0004] Waste heat recovery machines transport water through pipelines during heat exchange. Existing waste heat recovery machine pipelines are connected by flanges, and a sealing ring is installed between the two flanges for sealing. However, the sealing ring is exposed to the external environment and is susceptible to environmental corrosion, which reduces the service life of the sealing ring. Therefore, a new sealing structure for air compressor waste heat recovery machines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel sealing structure for an air compressor waste heat recovery machine, aiming to improve the problem that the sealing ring is easily corroded in the prior art, resulting in a reduced service life of the sealing ring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel sealing structure for a waste heat recovery machine for air compressors includes a first pipe and a second pipe. The bottom end of the second pipe is slidably connected to the inside of the first pipe. A sealing component is provided inside the first pipe. A plurality of evenly distributed protrusions are slidably connected to the inside of the top end of the first pipe. One side of each protrusion is slidably connected to the inside of the bottom end of the second pipe. A sliding sleeve is slidably connected to the outer periphery of the first pipe. The inner side of the sliding sleeve abuts against the outer periphery of the protrusions. A spring is sleeved on the outer periphery of the first pipe, and the top end of the spring abuts against the inside of the sliding sleeve.

[0008] As a further description of the above technical solution:

[0009] The sealing assembly includes a sealing ring, which is slidably connected to the inner side of a bottom end of the pipe. A support ring is fixedly connected to the inner side of a bottom end of the pipe, and the support ring abuts against the bottom side of the sealing ring.

[0010] As a further description of the above technical solution:

[0011] A baffle is fixedly connected to the outer periphery of the pipe, and the top side of the sliding sleeve abuts against the bottom side of the baffle.

[0013] A limiting plate is fixedly connected to the outer periphery of the protrusion, and a plurality of evenly distributed limiting grooves are opened inside the pipe. The limiting plate is slidably connected inside the limiting grooves.

[0014] As a further description of the above technical solution:

[0015] A fixing ring is fixedly connected to the outer periphery of the pipe, and the bottom end of the spring abuts against the top side of the fixing ring.

[0016] As a further description of the above technical solution:

[0017] A storage groove is provided on the inner side of the top side of the sliding sleeve;

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The sealing ring is provided with a metallized coating on its outer periphery, and a silicone coating is provided on its outer periphery.

[0022] This utility model has the following beneficial effects:

[0023] In this invention, pipe two is inserted into pipe one to connect the two pipes. A spring pushes a sliding sleeve to move, which restricts the movement of multiple protrusions. The protrusions are fixed inside pipe one and pipe two, which can fix pipe two inside pipe one. The sliding sleeve slides inside pipe one to protect the connection structure between pipe one and pipe two, thereby maintaining the sealing between pipe one and pipe two.

[0024] In this invention, a sealing ring is installed inside the first pipe. The contact between the second pipe and the sealing ring enhances the sealing performance between the first and second pipes. The outer surface of the sealing ring is coated with a silicone coating to improve its high temperature resistance and corrosion resistance. The outer surface of the sealing ring is coated with a metallized coating, which enhances the structural strength and stability of the sealing ring, making it more adaptable to the requirements of high pressure and high temperature working conditions.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2This utility model provides an embodiment of a novel sealing structure for a waste heat recovery machine for air compressors, comprising a first pipe 2 and a second pipe 4. The bottom end of the second pipe 4 is slidably connected to the inside of the first pipe 2. The first pipe 2 and the second pipe 4 are used to transport water flow. Multiple evenly distributed protrusions 9 are slidably connected to the inside of the top end of the first pipe 2. One side of each protrusion 9 is slidably connected to the inside of the bottom end of the second pipe 4. Inserting the protrusions 9 into the bottom end of the second pipe 4 can fix the bottom end of the second pipe 4 inside the first pipe 2. A limiting plate 5 is fixedly connected to the outer periphery of each protrusion 9. Multiple evenly distributed limiting grooves are provided inside the first pipe 2. The limiting plate 5 is slidably connected to the limiting grooves, and sliding within the limiting grooves can restrict the protrusions 9. The pipe 2 is slidably connected to a sliding sleeve 3, the inner side of which abuts against the outer side of the protrusion 9. The sliding sleeve 3 restricts the movement of the protrusion 9. A spring 8 is sleeved on the outer side of the pipe 2, the top of which abuts against the inside of the sliding sleeve 3. The spring 8 is used to push the sliding sleeve 3 to move. A fixing ring 7 is fixedly connected to the outer side of the pipe 2, the bottom end of which abuts against the top side of the fixing ring 7. The fixing ring 7 is used to fix the spring 8. A baffle 1 is fixedly connected to the outer side of the pipe 2, the top side of which abuts against the bottom side of the baffle 1. The baffle 1 is used to restrict the movement of the sliding sleeve 3. A storage groove 10 is opened on the inner side of the top side of the sliding sleeve 3, and the protrusion 9 can slide into the storage groove 10 for storage.

[0033] Reference Figure 3 , Figure 4 Pipe 1 2 is equipped with a sealing assembly, which includes a sealing ring 11. The sealing ring 11 enhances the sealing performance of the connection between pipe 1 2 and pipe 2 4. The sealing ring 11 is slidably connected to the inner side of the bottom end of pipe 1 2. A support ring 6 is fixedly connected to the inner side of the bottom end of pipe 1 2. The support ring 6 abuts against the bottom side of the sealing ring 11 and supports the sealing ring 11. The sealing ring 11 is made of rubber, which gives it good elasticity and sealing performance. The outer periphery of the sealing ring 11 is provided with a metallized coating 12. The metallized coating 12 enhances the structural strength and stability of the sealing ring 11, making it more adaptable to high pressure and high temperature working environments. The outer periphery of the metallized coating 12 is provided with a silicone coating 13, which can improve the high temperature resistance and corrosion resistance of the sealing ring 11.

[0034] Working principle: When pipe 2 4 is inserted into pipe 1 2, it pushes the sliding sleeve 3 to move, so that the sliding sleeve 3 no longer restricts the movement of multiple protrusions 9. When pipe 2 4 is inserted into pipe 1 2, pipe 2 4 pushes multiple protrusions 9 into the receiving groove 10, so that pipe 2 4 can be smoothly inserted into pipe 1 2. After the bottom end of pipe 2 4 contacts the sealing ring 11, the sliding sleeve 3 can be released. The sliding sleeve 3 is pushed by the spring 8 to move. During the movement of the sliding sleeve 3, it pushes multiple protrusions 9 into pipe 2 4. After one side of multiple protrusions 9 is inserted into pipe 2 4, pipe 2 4 can be fixed inside pipe 1 2. After the sliding sleeve 3 is pushed by the spring 8 to contact the baffle 1, it can restrict the movement of multiple protrusions 9. After pipe 1 (2) and pipe 2 (4) are connected, water can be transported. The contact between pipe 2 (4) and sealing ring 11 can increase the sealing performance at the connection between pipe 1 (2) and pipe 2 (4). The outer circumference of sealing ring 11 is coated with a metallized coating 12, which can enhance the structural strength and stability of sealing ring 11, making it more adaptable to high pressure and high temperature working environments. The outer circumference of metallized coating 12 is coated with a silicone coating 13, which can improve the high temperature resistance and corrosion resistance of sealing ring 11. The metallized coating 12 and silicone coating 13 can improve the stability and sealing performance of sealing ring 11, thereby enhancing the sealing effect and service life of sealing ring 11.
