Description

Technical Field

[0001] This invention relates to the field of double-layer explosion-proof electrical isolation technology, specifically to an explosion-proof compressor and a jet loom. Background Technology

[0002] In certain specialized fields, such as coal mines and chemical industries, there are challenges related to high temperatures, high humidity, and extremely harsh working environments. To improve the quality of working conditions, the market demand for refrigeration technologies in these specialized fields is constantly growing. Therefore, highly reliable explosion-proof air conditioning products are a new area that urgently needs to be addressed and resolved. Currently, only large-scale central air conditioning refrigeration equipment and related compressors are available for high-risk environments such as mines. There are no relevant air conditioning technologies or explosion-proof compressors suitable for small caverns and tunnels.

[0003] Specifically, explosion-proof compressors are pressure vessels inside equipment such as air conditioners. They are typically welded to prevent external gases from entering, thus preventing hazardous media from contacting ignition sources and achieving explosion protection. However, traditional explosion-proof compressors have two main problems: first, relying solely on the compressor casing for explosion protection is ineffective with a single layer and can easily spread to the outside environment in the event of an explosion; second, the efficiency of exhausting air through the exhaust pipe in traditional explosion-proof compressors is low, resulting in high temperatures in the compressor casing and internal components that cannot be cooled quickly enough, making them prone to explosion. In summary, existing technologies for electrical explosion protection of explosion-proof compressors have limitations. Summary of the Invention

[0004] This invention proposes an explosion-proof compressor, which solves the problem of poor electrical explosion-proof performance of explosion-proof compressors in related technologies.

[0005] The technical solution of the present invention is as follows:

[0006] An explosion-proof compressor includes: a compressor core and a compressor housing sleeved outside the compressor core, wherein a hollow terminal and an exhaust pipe are coupled to the outer wall of the compressor housing;

[0007] The compressor housing is provided with a cable protection shell and a sealing cover that is sealed to the outer ring of the cable protection shell.

[0008] A rigid gasket is placed between the sealing cap and the cable protection shell;

[0009] An explosion-proof medium is filled between the rigid gasket and the cable protective shell;

[0010] The space between the rigid gasket and the sealing cap is filled with an airtight elastic medium;

[0011] By screwing on the sealing cap, the elastic medium is compressed between the rigid gasket and the sealing cap to form a sealing structure;

[0012] When the compressor core explodes, the explosive gas enters the cable protection shell through the hollow terminal. The explosion-proof medium and the elastic medium provide double buffering for the explosive gas, reducing the impact of the explosion.

[0013] Preferably, the cable protection shell has a double-hole stepped configuration.

[0014] Preferably, the sealing cap, the cable protection shell, and the rigid gasket are all made of metal materials, including stainless steel.

[0015] Preferably, the explosion-proof medium is epoxy resin, and the elastic medium is rubber material, wherein the rubber material includes a rubber ring.

[0016] Preferably, a spherical wall is provided between the compressor inner core and the compressor housing;

[0017] An opening is provided at the top of the sphere, through which the exhaust pipe is connected;

[0018] When the temperature of the compressor housing is too high, the high-temperature gas inside the compressor housing is discharged and cooled by connecting to the exhaust pipe through the opening in the spherical wall.

[0019] Preferably, the sphere wall is made of a metallic material, wherein the metallic material includes stainless steel.

[0020] Preferably, the spherical wall has a hemispherical structure.

[0021] Preferably, an annular wall is provided above the compressor housing for monitoring the temperature and pressure of the compressor core;

[0022] The ring wall is a device in which several metal rings are connected by a flexible material, and the ring wall is a stretchable tubular structure.

[0023] When the temperature and pressure inside the compressor core reach a certain value, the gas inside the compressor core is discharged through the metal ring of the ring wall, thereby achieving cooling and pressure reduction.

[0024] Preferably, the metal ring is made of stainless steel, and the flexible material is made of rubber.

[0025] Furthermore, the present invention provides an air-jet loom comprising the explosion-proof compressor as described above, characterized in that the air-jet loom is provided with a detachable explosion-proof compressor.

[0026] The working principle and beneficial effects of this invention are as follows:

[0027] 1. In this invention, the space between the rigid gasket and the cable protection shell of the double-layer explosion-proof device inside the explosion-proof compressor is filled with an explosion-proof medium, and the space between the rigid gasket and the sealing cover is filled with an elastic medium. By screwing the sealing cover, the elastic medium is compressed between the rigid gasket and the sealing cover to form a sealing structure. When the compressor core explodes, the explosion-proof medium and the elastic medium form a double explosion-proof barrier, which can reduce the impact of the explosion and improve the effect and efficiency of electrical explosion-proof.

[0028] 2. In this invention, many components of the compressor are made of stainless steel, which has the characteristics of corrosion resistance, high temperature strength, and aesthetics. The connection of many components is made by welding, which can improve the stability during installation and has good practical performance.

[0029] 3. In this invention, the explosion-proof compressor, which is composed of the compressor core, compressor housing, exhaust pipe, ring wall, ball wall, double-layer explosion-proof device and hollow terminal block, can achieve double electrical explosion protection compared with traditional compressors, so that when an explosion occurs inside the compressor, it will not affect the outside world, and can solve the problem of high temperature of compressor housing and compressor exhaust pipe.

[0030] 4. In this invention, one end of the cable protection shell in the double-layer explosion-proof device has a double-hole stepped structure, which can meet the wiring operation space requirements. At the same time, the stepped surface serves as the compressor's built-in grounding platform, realizing functions such as compressor grounding nearby, built-in grounding, and grounding isolation, avoiding the safety hazards of external grounding. The other end has an external thread structure, which can better fix, connect, and transmit force, with good reliability and durability.

[0031] 5. In this invention, the space between the rigid gasket and the cable protection shell in the double-layer explosion-proof device is filled with an explosion-proof medium, wherein the explosion-proof medium is epoxy resin, which has excellent chemical resistance, strong paint film adhesion, good heat resistance, electrical insulation and good paint film color retention, and can better achieve electrical explosion protection.

[0032] 6. In this invention, the ring wall is a stretchable tubular structure, which is connected by a number of rigid metal rings arranged at equal intervals with flexible material to achieve the purpose of stretchability. The flexible material includes high temperature resistant and flame retardant rubber material, including silicone rubber or foamed rubber, which has the characteristics of being sticky, soft, compressible, and waterproof, and can achieve the flame retardancy and oxidation resistance when the metal rings are connected.

[0044] Example 1:

[0045] Please see Figure 1 An explosion-proof compressor, comprising:

[0046] Compressor core 1;

[0047] The compressor housing 2 is disposed outside the compressor inner core 1 and is connected to the compressor inner core 1 by fasteners;

[0048] The exhaust pipe 3 is located on the left side of the compressor housing 2, and is connected to the compressor housing 2 by welding and to the ball wall 4 by connecting wire.

[0049] A spherical wall 4 is provided between the compressor inner core 1 and the compressor housing 2, and is connected to the compressor inner core 1 and the compressor housing 2 by welding;

[0050] An annular wall 5 is provided above the compressor housing 2 for monitoring the temperature and pressure of the compressor core, and is connected to the compressor housing 2 by welding.

[0051] A double-layer explosion-proof device 6 is located on the upper left side of the compressor housing 2 and is connected to the compressor housing 2 by welding.

[0052] Hollow terminal 7 is disposed between the compressor housing 2 and the double-layer explosion-proof device 6.

[0053] In detail, the compressor core 1 includes components such as a compressor cylinder, crankshaft, connecting rod, piston, piston rings, and motor; wherein, the compressor cylinder is the component that isolates the compression chamber of the compressor from the external environment, and is mostly made of cast iron with a smooth surface; the crankshaft is responsible for converting the linear motion of the piston into rotational motion, so as to realize the compression process, and is commonly made of steel, cast iron, or copper alloy, with sufficient strength, rigidity, and wear resistance.

[0054] Furthermore, the connecting rod is a component that converts the rotational motion of the crankshaft into the reciprocating motion of the piston. One end is connected to the piston, and the other end is connected to the crankshaft. It is generally made of alloy steel. The piston is located inside the cylinder and is mainly responsible for compressing and releasing gas. The piston is the core component of the directional cylinder and is mostly made of high-strength aluminum alloy. The piston ring is an annular structure and is installed on the piston to prevent compressed gas leakage. The motor can convert electrical energy into mechanical energy and mainly serves to drive the compressor to rotate.

[0055] Furthermore, the cast iron material refers to the general term for alloys composed of iron, carbon, and silicon, that is, iron-carbon alloys with a carbon content of more than 2.11%, including gray cast iron, white cast iron, and mottled cast iron.

[0056] In detail, the term "steel" refers to the general term for steel and pig iron. Iron-carbon alloys with a carbon mass fraction greater than 2% are called pig iron, while iron-carbon alloys with a carbon mass fraction between 0.02% and 2.11% are called steel. The term "copper alloy" refers to the material made by using pure copper or red copper as the base material, then adding other alloy materials in proportion, and finally processing them through various processes.

[0057] In detail, the compressor housing 2 is disposed outside the compressor inner core 1 and is connected to the compressor inner core 1 by fasteners. The fasteners can be bolts, which are mechanical parts consisting of a head and a screw (a cylinder with external threads), and are detachable.

[0058] Furthermore, the compressor housing 2 can be made of cast aluminum alloy, steel plate or ABS. Cast aluminum alloy is one of the most commonly used materials for compressor housings. It has the characteristics of light weight, high strength, high precision, corrosion resistance and good durability. It is also easy to process and surface treat, so it has a high aesthetic appeal.

[0059] Specifically, the steel plate is also a commonly used compressor housing material, which has the characteristics of high strength, corrosion resistance, wear resistance and heat resistance, and is suitable for making large high-pressure compressor housings. It also has good plasticity. The ABS is a plastic material, which has the characteristics of light weight, impact resistance, corrosion resistance and good insulation performance. It is suitable for making small, lightweight compressor housings and can be treated with painting, electroplating and other processes.

[0060] Specifically, the exhaust pipe 3 refers to the pipe that discharges the high-pressure gas generated by the compressor. It is located on the left side of the compressor housing 2, which is the outlet of the compressor. The exhaust pipe is generally made of metal material and has high temperature resistance and corrosion resistance to ensure the safe and stable operation of the compressor.

[0061] Furthermore, the exhaust pipe 3 is connected to the compressor housing 2 by welding. Welding refers to fusion welding, which is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Commonly used methods include electric arc welding, argon arc welding, and laser welding.

[0062] In detail, the exhaust pipe 3 is connected to the ball wall 4 by means of a connecting wire. This means that the ball wall 4 has an opening at its top, and the line of the exhaust pipe 3 can be led out from the opening at the top of the ball wall 4 to achieve the connection.

[0063] Specifically, the spherical wall 4 is located between the compressor inner core 1 and the compressor housing 2, and is connected to the compressor inner core 1 and the compressor housing 2 by welding; the spherical wall is made of stainless steel, wherein stainless steel refers to steel with rust resistance and corrosion resistance as its main characteristics, and a chromium content of at least 10.5% and a carbon content of no more than 1.2%. Specifically, stainless steel is an abbreviation for stainless and acid-resistant steel. Steels that are resistant to weak corrosive media such as air, steam, and water or have rust resistance are called stainless steel; while steels that are resistant to chemical corrosion media (acids, alkalis, salts, etc.) are called acid-resistant steel.

[0064] Furthermore, the structure of the spherical wall 4 is a hemispherical structure, wherein the top of the sphere has an opening for the exhaust pipe 3 to pass through the motor lead wire in the compressor inner core 1; after the exhaust pipe 3 and the compressor inner core 1 pass through the wire, the opening of the spherical wall 4 is sealed with a sealing ring.

[0065] Specifically, the sealing ring refers to a rubber product mainly used to fill leaks or prevent the leakage of substances such as gas and liquid. It has the characteristics of good elasticity, corrosion resistance, and high temperature resistance, and includes O-rings, V-rings, Y-rings, and X-rings.

[0066] In detail, since the compressor is constantly venting, some abnormal working conditions may cause the compressor interior to reach high temperatures due to the exhaust pressure. By setting the ball wall 4, the high temperature inside the compressor caused by the exhaust pressure is isolated from the external wiring, reducing the high temperature problem of the compressor casing caused by the exhaust pressure and avoiding the explosion-proof safety hazards caused by the high temperature of the compressor casing.

[0067] Furthermore, a temperature and pressure sensor is securely mounted on the spherical wall 4, which can monitor the temperature and pressure values ​​of the compressor core 1 in real time. The temperature and pressure are transmitted to the annular wall 5 through the compressor housing 2. When the compressor is operating abnormally, abnormal pressure and temperature values ​​inside the compressor are detected, and the annular wall 5 is controlled to expand and contract to prevent the exhaust pipe from exploding and posing a safety risk to the outside world.

[0068] Specifically, the annular wall 5 is a retractable tubular structure, which is connected to the compressor housing 2 by welding, such as... Figure 2 The diagram shows a specific structural schematic of the ring wall 5. It is constructed by connecting several rigid metal rings arranged at equal intervals with flexible materials to achieve the purpose of stretchability. The metal rings are made of stainless steel, and the flexible materials include high-temperature resistant and flame-retardant rubber materials.

[0069] Furthermore, the rubber material can be silicone rubber or foamed rubber, wherein both silicone rubber and foamed rubber belong to silicone elastomers; the silicone rubber is made from silanes and other main raw materials, and has properties such as high-temperature crack resistance and wear resistance; the foamed rubber is made from chemical raw materials such as dimethylsiloxane (PDMS), vinyl ethylamide (VEOVA), and tert-butyl carbonyl peroxide (POBO), and has properties such as viscosity, softness, compressibility, and good water resistance; both can be used as flexible thermal conductive materials to achieve flame retardancy and oxidation resistance when the metal rings are connected.

[0070] Specifically, one end of the annular wall 5 is welded to the boss of the compressor housing 2. The temperature and pressure values ​​inside the compressor are transmitted to the annular wall 5 in real time through the temperature and pressure sensor of the inner ball wall 4 of the compressor. When the temperature and pressure inside the compressor reach the limit value, the annular wall 5 is controlled to extend and retract to the condenser boss to form a heat insulation annular wall. This prevents the risk of explosion of the exhaust pipe 3 caused by excessive pressure from the exhaust pipe 3 from threatening the environment outside the compressor, and provides explosion-proof protection for the exhaust pipe 3.

[0071] Specifically, the double-layer explosion-proof device 6 is located on the upper left side of the compressor housing 2. The double-layer explosion-proof device 6 includes a cable protection housing 61, a sealing cover 62, and a rigid gasket 63. Figure 3 The diagram shown illustrates the specific structure of the double-layer explosion-proof device 6.

[0072] Furthermore, a cable protection shell 61 and a sealing cover 62 that are sealed to the outer ring of the cable protection shell 61 are provided on the upper part of the compressor housing 2; a rigid gasket 63 is provided between the sealing cover 62 and the cable protection shell 61; an explosion-proof medium is filled between the rigid gasket 63 and the cable protection shell 61; and an airtight elastic medium is filled between the rigid gasket 63 and the sealing cover 62.

[0073] Specifically, the compressor housing 2 and the cable protection housing 61 are connected by welding. Welding refers to fusion welding, which is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Commonly used methods include electric arc welding, argon arc welding and laser welding.

[0074] Furthermore, the cable protection shell 61 is designed with a double-hole stepped configuration. The first hole is used to pass through the hollow terminal 7, and the second stepped hole meets the space requirements for wiring operations. At the same time, the stepped surface serves as the compressor's built-in grounding platform, realizing functions such as compressor grounding nearby, built-in grounding, and grounding isolation, thus avoiding the safety hazards of external grounding.

[0075] In detail, after the cable protection shell 61 is welded, the compressor cable is assembled onto the hollow terminal 7. After assembly, the outer ring of the cable protection shell 61 is sealed with the sealing cover 62. The cable protection shell 61 and the sealing cover 62 are both made of stainless steel, which refers to steel that is corrosion-resistant in the atmosphere and in weakly corrosive media.

[0076] Furthermore, the outer ring of the cable protection shell 61 is sealed to the sealing cover 62, and the cable protection shell 61 can be designed with an external thread structure. The thread structure refers to a spiral shape structure, commonly found in mechanical parts such as threaded steel, screws, and nuts. A spiral is a curve formed by a point continuously rotating around an axis in space, and has a certain degree of straightness and rotation. An external thread refers to the thread on a threaded rod, which is often used to connect parts and transmit force. Its main purpose is to fix, connect, and transmit force, and its advantages are good reliability and durability.

[0077] Specifically, a rigid gasket 63 is provided between the sealing cover 62 and the cable protection shell 61. The rigid gasket 63 is made of stainless steel and is used to bear the compressive force of the rubber ring.

[0078] Furthermore, the space between the rigid gasket 63 and the cable protective shell 61 is filled with an explosion-proof medium, which refers to epoxy resin. Epoxy resin is a high molecular polymer with the molecular formula (C11H12O3)n. It is a general term for a class of polymers containing two or more epoxy groups in their molecules. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of epoxy groups, it can be opened by various compounds containing active hydrogen, and cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin.

[0079] Specifically, the epoxy resin possesses excellent physical, mechanical, and electrical insulation properties, adhesion to various materials, and flexibility in its application process, which are not found in other thermosetting plastics. It also exhibits excellent chemical resistance, especially alkali resistance, strong paint film adhesion, good heat resistance and electrical insulation, and good color retention of the paint film.

[0080] Furthermore, the space between the rigid gasket 63 and the sealing cap 62 is filled with an airtight elastic medium, wherein the elastic medium refers to a rubber ring of appropriate size. The rubber ring is made of rubber, which is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed.

[0081] In detail, after the cable protection shell 61 is welded, the compressor cable is assembled onto the hollow terminal 7. After assembly, the cable protection shell 61 is filled with explosion-proof medium. After the explosion-proof medium dries, a hard gasket 63 of appropriate size and an elastic medium are placed on the top in sequence. Then, the sealing cap 62 is fitted into the cable protection shell 61 and connected by threads. During the tightening of the metal sealing cap 62, the elastic medium is squeezed to achieve the purpose of locking and sealing the cable, and the hard gasket 63 bears the squeezing force of the elastic medium.

[0082] Specifically, the double-layer explosion-proof device 6 refers to the explosion-proof medium as the first layer of explosion protection, and the sealing cover 62 as the second layer of explosion protection, which locks the cable by squeezing the elastic medium during the tightening process. Electrical explosion protection is achieved through the above two layers of explosion protection, so that an explosion inside the compressor will not affect the outside world through the wiring device.

[0083] Specifically, the hollow terminal 7 is disposed between the compressor housing 2 and the double-layer explosion-proof device 6. The hollow terminal 7 refers to an electrical connection device used to connect two or more wires or cables to facilitate current or signal transmission. The hollow terminal 7 is made of stainless steel, which has excellent corrosion resistance and high strength. When the compressor core 1 explodes, the explosive gas is transmitted into the cable protection housing through the hollow terminal 7, so that the explosion-proof medium and the elastic medium provide double buffering for the explosive gas, reducing the impact of the explosion.

[0084] Working principle and usage process:

[0085] First, the compressor housing 2 cannot operate normally when the compressor inner core 1 is not installed, and the compressor inner core 1 needs to be installed inside the compressor housing 2. Otherwise, if the compressor inner core 1 explodes, it will easily have a huge impact on the outside world. When the compressor inner core 1 and the compressor housing 2 are connected by fasteners, the compressor can operate normally.

[0086] However, the compressor also needs to include an exhaust pipe 3. When the compressor does not have the exhaust pipe, the generated gas cannot be discharged well. Therefore, the exhaust pipe 3 needs to be installed on the left side of the compressor housing 2 by welding. At this time, the gas generated by the compressor can be discharged in a preliminary manner.

[0087] Next, since the compressor is constantly venting, the exhaust pipe 3 cannot promptly detect the high temperature of the compressor housing 2 caused by the abnormal operating conditions inside the compressor. Therefore, the efficiency of the exhaust pipe 3 is low. So, a ball wall 4 is designed between the compressor core 1 and the compressor housing 2. An opening is made at the top of the ball wall 4 to connect the exhaust pipe 3 and the motor of the compressor core 1. When the motor is malfunctioning or the temperature is high, the high-temperature gas is directly discharged through the exhaust pipe 3 connected to the ball wall 4, reducing the high temperature problem of the compressor housing 2 caused by the exhaust pressure and avoiding the explosion-proof safety hazard caused by the high temperature of the compressor housing 2.

[0088] Furthermore, since the compressor exhaust pipe 3 may experience temperature and pressure increases due to motor heating and elevated return gas temperature, potentially leading to an explosion risk, an annular wall 5 is designed. One end is welded to the compressor housing 2, and the other end is connected to the condenser. Temperature and pressure sensors transmit the internal temperature and pressure values ​​of the compressor to the annular wall 5 in real time. When the internal temperature and pressure of the compressor reach the specified values, the annular wall 5 is controlled to extend and retract onto the condenser protrusion, forming a heat-insulating annular wall. This prevents the risk of the compressor exhaust pipe 3 exploding due to excessive pressure from threatening the environment outside the compressor, thus providing explosion-proof protection for the exhaust pipe 3.

[0089] In addition, to prevent an explosion inside the compressor from affecting the outside world through the wiring device, a double-layer explosion-proof device 6 is designed. The double-layer explosion-proof device forms a double layer of electrical explosion protection through components such as the cable protection shell 61, the sealing cover 62, and the rigid gasket 63. Specifically, an explosion-proof medium is filled between the rigid gasket 63 and the cable protection shell 61 to form the first layer of explosion protection. An airtight elastic medium is filled between the rigid gasket 63 and the sealing cover 62. One end of the cable protection shell 61 is set with an external thread structure. Through the threaded connection, the elastic medium is squeezed during the tightening of the metal sealing cover 62 to lock and seal the cable. The rigid gasket 63 bears the squeezing force of the elastic medium to achieve the second layer of explosion protection.

[0090] Furthermore, since an explosion of the compressor core 1 will produce explosive gas, it is necessary to transfer the explosive gas generated by the compressor core 1 to the double-layer explosion-proof device 6. Therefore, a hollow terminal 7 is designed between the compressor housing 2 and the double-layer explosion-proof device 6 to transfer the explosive gas to the double-layer explosion-proof device 6, thereby preventing the explosive gas from affecting the outside world.

[0091] Finally, the operation of the explosion-proof compressor is as follows: the power supply is connected via the cable protection shell 61 in the double-layer explosion-proof device, and the electrical energy of the power supply is converted into mechanical energy to enable the explosion-proof compressor to run. The exhaust pipe 3 continuously discharges gas. When the motor is malfunctioning or the temperature is too high, the high-temperature gas is discharged directly through the ball wall 4 connected to the exhaust pipe 3. When the temperature of the compressor exhaust pipe 3 rises or the pressure is too high due to motor heating, return gas temperature increase, etc., the temperature and pressure values ​​inside the compressor are transmitted to the ring wall 5 in real time through the temperature and pressure sensor, and the ring wall 5 is controlled to extend and retract onto the condenser protrusion to form a heat insulation ring wall. When the compressor core 1 explodes, the generated explosive gas is transmitted to the double-layer explosion-proof device 6 through the hollow terminal 7. The explosion-proof medium and the elastic medium provide double buffering for the explosive gas to prevent the explosive gas from spreading and affecting the outside world.

[0092] Example 2:

[0093] Furthermore, the present invention provides a jet loom comprising the explosion-proof compressor as described above, characterized in that the explosion-proof compressor is detachably disposed within the jet loom.

[0094] The explosion-proof compressor inside the jet loom can be found in [reference]. Figure 1 ,include:

[0096] The compressor housing 2 is disposed outside the compressor inner core 1 and is connected to the compressor inner core 1 by fasteners;

[0097] The exhaust pipe 3 is located on the left side of the compressor housing 2, and is connected to the compressor housing 2 by welding and to the ball wall 4 by connecting wire.

[0101] Hollow terminal 7 is disposed between the compressor housing 2 and the double-layer explosion-proof device 6.

[0102] In detail, the compressor core 1 includes components such as a compressor cylinder, crankshaft, connecting rod, piston, piston rings, and motor; wherein, the compressor cylinder is the component that isolates the compression chamber of the compressor from the external environment, and is mostly made of cast iron with a smooth surface; the crankshaft is responsible for converting the linear motion of the piston into rotational motion, so as to realize the compression process, and is commonly made of steel, cast iron, or copper alloy, with sufficient strength, rigidity, and wear resistance.

[0103] Furthermore, the connecting rod is a component that converts the rotational motion of the crankshaft into the reciprocating motion of the piston. One end is connected to the piston, and the other end is connected to the crankshaft. It is generally made of alloy steel. The piston is located inside the cylinder and is mainly responsible for compressing and releasing gas. The piston is the core component of the directional cylinder and is mostly made of high-strength aluminum alloy. The piston ring is an annular structure and is installed on the piston to prevent compressed gas leakage. The motor can convert electrical energy into mechanical energy and mainly serves to drive the compressor to rotate.

[0104] Furthermore, the cast iron material refers to the general term for alloys composed of iron, carbon, and silicon, that is, iron-carbon alloys with a carbon content of more than 2.11%, including gray cast iron, white cast iron, and mottled cast iron.

[0105] In detail, the term "steel" refers to the general term for steel and pig iron. Iron-carbon alloys with a carbon mass fraction greater than 2% are called pig iron, while iron-carbon alloys with a carbon mass fraction between 0.02% and 2.11% are called steel. The term "copper alloy" refers to the material made by using pure copper or red copper as the base material, then adding other alloy materials in proportion, and finally processing them through various processes.

[0106] In detail, the compressor housing 2 is disposed outside the compressor inner core 1 and is connected to the compressor inner core 1 by fasteners. The fasteners can be bolts, which are mechanical parts consisting of a head and a screw (a cylinder with external threads), and are detachable.

[0107] Furthermore, the compressor housing 2 can be made of cast aluminum alloy, steel plate or ABS. Cast aluminum alloy is one of the most commonly used materials for compressor housings. It has the characteristics of light weight, high strength, high precision, corrosion resistance and good durability. It is also easy to process and surface treat, so it has a high aesthetic appeal.

[0108] Specifically, the steel plate is also a commonly used compressor housing material, which has the characteristics of high strength, corrosion resistance, wear resistance and heat resistance, and is suitable for making large high-pressure compressor housings. It also has good plasticity. The ABS is a plastic material, which has the characteristics of light weight, impact resistance, corrosion resistance and good insulation performance. It is suitable for making small, lightweight compressor housings and can be treated with painting, electroplating and other processes.

[0109] Specifically, the exhaust pipe 3 refers to the pipe that discharges the high-pressure gas generated by the compressor. It is located on the left side of the compressor housing 2, which is the outlet of the compressor. The exhaust pipe is generally made of metal material and has high temperature resistance and corrosion resistance to ensure the safe and stable operation of the compressor.

[0110] Furthermore, the exhaust pipe 3 is connected to the compressor housing 2 by welding. Welding refers to fusion welding, which is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Commonly used methods include electric arc welding, argon arc welding, and laser welding.

[0111] In detail, the exhaust pipe 3 is connected to the ball wall 4 by means of a connecting wire. This means that the ball wall 4 has an opening at its top, and the line of the exhaust pipe 3 can be led out from the opening at the top of the ball wall 4 to achieve the connection.

[0112] Specifically, the spherical wall 4 is located between the compressor inner core 1 and the compressor housing 2, and is connected to the compressor inner core 1 and the compressor housing 2 by welding; the spherical wall is made of stainless steel, wherein stainless steel refers to steel with rust resistance and corrosion resistance as its main characteristics, and a chromium content of at least 10.5% and a carbon content of no more than 1.2%. Specifically, stainless steel is an abbreviation for stainless and acid-resistant steel. Steels that are resistant to weak corrosive media such as air, steam, and water or have rust resistance are called stainless steel; while steels that are resistant to chemical corrosion media (acids, alkalis, salts, etc.) are called acid-resistant steel.

[0113] Furthermore, the structure of the spherical wall 4 is a hemispherical structure, wherein the top of the sphere has an opening for the exhaust pipe 3 to pass through the motor lead wire in the compressor inner core 1; after the exhaust pipe 3 and the compressor inner core 1 pass through the wire, the opening of the spherical wall 4 is sealed with a sealing ring.

[0114] Specifically, the sealing ring refers to a rubber product mainly used to fill leaks or prevent the leakage of substances such as gas and liquid. It has the characteristics of good elasticity, corrosion resistance, and high temperature resistance, and includes O-rings, V-rings, Y-rings, and X-rings.

[0115] In detail, since the compressor is constantly venting, some abnormal working conditions may cause the compressor interior to reach high temperatures due to the exhaust pressure. By setting the ball wall 4, the high temperature inside the compressor caused by the exhaust pressure is isolated from the external wiring, reducing the high temperature problem of the compressor casing caused by the exhaust pressure and avoiding the explosion-proof safety hazards caused by the high temperature of the compressor casing.

[0116] Furthermore, a temperature and pressure sensor is securely mounted on the spherical wall 4, which can monitor the temperature and pressure values ​​of the compressor core 1 in real time. The temperature and pressure are transmitted to the annular wall 5 through the compressor housing 2. When the compressor is operating abnormally, abnormal pressure and temperature values ​​inside the compressor are detected, and the annular wall 5 is controlled to expand and contract to prevent the exhaust pipe from exploding and posing a safety risk to the outside world.

[0117] Specifically, the annular wall 5 is a retractable tubular structure, which is connected to the compressor housing 2 by welding, such as... Figure 2 The diagram shows a specific structural schematic of the ring wall 5. It is constructed by connecting several rigid metal rings arranged at equal intervals with flexible materials to achieve the purpose of stretchability. The metal rings are made of stainless steel, and the flexible materials include high-temperature resistant and flame-retardant rubber materials.

[0118] Furthermore, the rubber material can be silicone rubber or foamed rubber, wherein both silicone rubber and foamed rubber belong to silicone elastomers; the silicone rubber is made from silanes and other main raw materials, and has properties such as high-temperature crack resistance and wear resistance; the foamed rubber is made from chemical raw materials such as dimethylsiloxane (PDMS), vinyl ethylamide (VEOVA), and tert-butyl carbonyl peroxide (POBO), and has properties such as viscosity, softness, compressibility, and good water resistance; both can be used as flexible thermal conductive materials to achieve flame retardancy and oxidation resistance when the metal rings are connected.

[0119] Specifically, one end of the annular wall 5 is welded to the boss of the compressor housing 2. The temperature and pressure values ​​inside the compressor are transmitted to the annular wall 5 in real time through the temperature and pressure sensor of the inner ball wall 4 of the compressor. When the temperature and pressure inside the compressor reach the limit value, the annular wall 5 is controlled to extend and retract to the condenser boss to form a heat insulation annular wall. This prevents the risk of explosion of the exhaust pipe 3 caused by excessive pressure from the exhaust pipe 3 from threatening the environment outside the compressor, and provides explosion-proof protection for the exhaust pipe 3.

[0120] Specifically, the double-layer explosion-proof device 6 is located on the upper left side of the compressor housing 2. The double-layer explosion-proof device 6 includes a cable protection housing 61, a sealing cover 62, and a rigid gasket 63. Figure 3 The diagram shown illustrates the specific structure of the double-layer explosion-proof device 6.

[0121] Furthermore, a cable protection shell 61 and a sealing cover 62 that are sealed to the outer ring of the cable protection shell 61 are provided on the upper part of the compressor housing 2; a rigid gasket 63 is provided between the sealing cover 62 and the cable protection shell 61; an explosion-proof medium is filled between the rigid gasket 63 and the cable protection shell 61; and an airtight elastic medium is filled between the rigid gasket 63 and the sealing cover 62.

[0122] Specifically, the compressor housing 2 and the cable protection housing 61 are connected by welding. Welding refers to fusion welding, which is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Commonly used methods include electric arc welding, argon arc welding and laser welding.

[0123] Furthermore, the cable protection shell 61 is designed with a double-hole stepped configuration. The first hole is used to pass through the hollow terminal 7, and the second stepped hole meets the space requirements for wiring operations. At the same time, the stepped surface serves as the compressor's built-in grounding platform, realizing functions such as compressor grounding nearby, built-in grounding, and grounding isolation, thus avoiding the safety hazards of external grounding.

[0124] In detail, after the cable protection shell 61 is welded, the compressor cable is assembled onto the hollow terminal 7. After assembly, the outer ring of the cable protection shell 61 is sealed with the sealing cover 62. The cable protection shell 61 and the sealing cover 62 are both made of stainless steel, which refers to steel that is corrosion-resistant in the atmosphere and in weakly corrosive media.

[0125] Furthermore, the outer ring of the cable protection shell 61 is sealed to the sealing cover 62, and the cable protection shell 61 can be designed with an external thread structure. The thread structure refers to a spiral shape structure, commonly found in mechanical parts such as threaded steel, screws, and nuts. A spiral is a curve formed by a point continuously rotating around an axis in space, and has a certain degree of straightness and rotation. An external thread refers to the thread on a threaded rod, which is often used to connect parts and transmit force. Its main purpose is to fix, connect, and transmit force, and its advantages are good reliability and durability.

[0126] Specifically, a rigid gasket 63 is provided between the sealing cover 62 and the cable protection shell 61. The rigid gasket 63 is made of stainless steel and is used to bear the compressive force of the rubber ring.

[0127] Furthermore, the space between the rigid gasket 63 and the cable protective shell 61 is filled with an explosion-proof medium, which refers to epoxy resin. Epoxy resin is a high molecular polymer with the molecular formula (C11H12O3)n. It is a general term for a class of polymers containing two or more epoxy groups in their molecules. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of epoxy groups, it can be opened by various compounds containing active hydrogen, and cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin.

[0128] Specifically, the epoxy resin possesses excellent physical, mechanical, and electrical insulation properties, adhesion to various materials, and flexibility in its application process, which are not found in other thermosetting plastics. It also exhibits excellent chemical resistance, especially alkali resistance, strong paint film adhesion, good heat resistance and electrical insulation, and good color retention of the paint film.

[0129] Furthermore, the space between the rigid gasket 63 and the sealing cap 62 is filled with an airtight elastic medium, wherein the elastic medium refers to a rubber ring of appropriate size. The rubber ring is made of rubber, which is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed.

[0130] In detail, after the cable protection shell 61 is welded, the compressor cable is assembled onto the hollow terminal 7. After assembly, the cable protection shell 61 is filled with explosion-proof medium. After the explosion-proof medium dries, a hard gasket 63 of appropriate size and an elastic medium are placed on the top in sequence. Then, the sealing cap 62 is fitted into the cable protection shell 61 and connected by threads. During the tightening of the metal sealing cap 62, the elastic medium is squeezed to achieve the purpose of locking and sealing the cable, and the hard gasket 63 bears the squeezing force of the elastic medium.

[0131] Specifically, the double-layer explosion-proof device 6 refers to the explosion-proof medium as the first layer of explosion protection, and the sealing cover 62 as the second layer of explosion protection, which locks the cable by squeezing the elastic medium during the tightening process. Electrical explosion protection is achieved through the above two layers of explosion protection, so that an explosion inside the compressor will not affect the outside world through the wiring device.

[0132] Specifically, the hollow terminal 7 is disposed between the compressor housing 2 and the double-layer explosion-proof device 6. The hollow terminal 7 refers to an electrical connection device used to connect two or more wires or cables to facilitate current or signal transmission. The hollow terminal 7 is made of stainless steel, which has excellent corrosion resistance and high strength. When the compressor core 1 explodes, the explosive gas is transmitted into the cable protection housing through the hollow terminal 7, so that the explosion-proof medium and the elastic medium provide double buffering for the explosive gas, reducing the impact of the explosion.

[0133] Working principle and usage process:

[0134] First, the compressor housing 2 cannot operate normally when the compressor inner core 1 is not installed, and the compressor inner core 1 needs to be installed inside the compressor housing 2. Otherwise, if the compressor inner core 1 explodes, it will easily have a huge impact on the outside world. When the compressor inner core 1 and the compressor housing 2 are connected by fasteners, the compressor can operate normally.

[0135] However, the compressor also needs to include an exhaust pipe 3. When the compressor does not have the exhaust pipe, the generated gas cannot be discharged well. Therefore, the exhaust pipe 3 needs to be installed on the left side of the compressor housing 2 by welding. At this time, the gas generated by the compressor can be discharged in a preliminary manner.

[0136] Next, since the compressor is constantly venting, the exhaust pipe 3 cannot promptly detect the high temperature of the compressor housing 2 caused by the abnormal operating conditions inside the compressor. Therefore, the efficiency of the exhaust pipe 3 is low. So, a ball wall 4 is designed between the compressor core 1 and the compressor housing 2. An opening is made at the top of the ball wall 4 to connect the exhaust pipe 3 and the motor of the compressor core 1. When the motor is malfunctioning or the temperature is high, the high-temperature gas is directly discharged through the exhaust pipe 3 connected to the ball wall 4, reducing the high temperature problem of the compressor housing 2 caused by the exhaust pressure and avoiding the explosion-proof safety hazard caused by the high temperature of the compressor housing 2.

[0137] Furthermore, since the compressor exhaust pipe 3 may experience temperature and pressure increases due to motor heating and elevated return gas temperature, potentially leading to an explosion risk, an annular wall 5 is designed. One end is welded to the compressor housing 2, and the other end is connected to the condenser. Temperature and pressure sensors transmit the internal temperature and pressure values ​​of the compressor to the annular wall 5 in real time. When the internal temperature and pressure of the compressor reach the specified values, the annular wall 5 is controlled to extend and retract onto the condenser protrusion, forming a heat-insulating annular wall. This prevents the risk of the compressor exhaust pipe 3 exploding due to excessive pressure from threatening the environment outside the compressor, thus providing explosion-proof protection for the exhaust pipe 3.

[0138] In addition, to prevent an explosion inside the compressor from affecting the outside world through the wiring device, a double-layer explosion-proof device 6 is designed. The double-layer explosion-proof device forms a double layer of electrical explosion protection through components such as the cable protection shell 61, the sealing cover 62, and the rigid gasket 63. Specifically, an explosion-proof medium is filled between the rigid gasket 63 and the cable protection shell 61 to form the first layer of explosion protection. An airtight elastic medium is filled between the rigid gasket 63 and the sealing cover 62. One end of the cable protection shell 61 is set with an external thread structure. Through the threaded connection, the elastic medium is squeezed during the tightening of the metal sealing cover 62 to lock and seal the cable. The rigid gasket 63 bears the squeezing force of the elastic medium to achieve the second layer of explosion protection.

[0139] Furthermore, since an explosion of the compressor core 1 will produce explosive gas, it is necessary to transfer the explosive gas generated by the compressor core 1 to the double-layer explosion-proof device 6. Therefore, a hollow terminal 7 is designed between the compressor housing 2 and the double-layer explosion-proof device 6 to transfer the explosive gas to the double-layer explosion-proof device 6, thereby preventing the explosive gas from affecting the outside world.

[0140] Finally, the operation of the explosion-proof compressor is as follows: the power supply is connected via the cable protection shell 61 in the double-layer explosion-proof device, and the electrical energy of the power supply is converted into mechanical energy to enable the explosion-proof compressor to run. The exhaust pipe 3 continuously discharges gas. When the motor is malfunctioning or the temperature is too high, the high-temperature gas is discharged directly through the ball wall 4 connected to the exhaust pipe 3. When the temperature of the compressor exhaust pipe 3 rises or the pressure is too high due to motor heating, return gas temperature increase, etc., the temperature and pressure values ​​inside the compressor are transmitted to the ring wall 5 in real time through the temperature and pressure sensor, and the ring wall 5 is controlled to extend and retract onto the condenser protrusion to form a heat insulation ring wall. When the compressor core 1 explodes, the generated explosive gas is transmitted to the double-layer explosion-proof device 6 through the hollow terminal 7. The explosion-proof medium and the elastic medium provide double buffering for the explosive gas to prevent the explosive gas from spreading and affecting the outside world.
