Description

Technical Field

[0001] This utility model belongs to the field of oxygen production equipment cooling technology, and specifically relates to a cooling water circulation mechanism for oxygen production. Background Technology

[0002] The oxygen generator cooling water circulation system is a system designed to provide cooling for components in oxygen generators that generate heat, such as compressors. This prevents the compressor lubricating oil from deteriorating due to high temperatures during operation, which can increase mechanical wear, reduce compressor efficiency and lifespan, and in severe cases, even cause equipment failure. The system also allows for the recycling of cooling water.

[0003] Current oxygen production cooling water circulation systems generally consist of a circulating water pump, cooling chamber, heat exchanger, water storage tank, pipes, and valves. Their working principle is as follows: First, air needs to be compressed, then cooled and liquefied to separate oxygen, nitrogen, and other gases. During storage and transportation, liquid oxygen usually needs to be vaporized into gaseous oxygen for user use.

[0004] However, existing cooling water circulation mechanisms are generally fixed to one side of the compressor when cooling it. This results in a limited contact area between the cooling water circulation mechanism and the compressor during use, making it impossible to completely enclose the compressor. Consequently, some areas still cannot fully contact the cooling water circulation mechanism, and the uncontacted parts are relatively difficult to dissipate heat, easily forming localized high-temperature areas, which will affect the performance and lifespan of the equipment in the long term. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling water circulation mechanism for oxygen generation. Its advantage is that by using air cooling and cooling water circulation mechanisms in combination, a dual-circulation heat dissipation is formed inside the oxygen generator, so that the compressor inside the oxygen generator can be fully cooled.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cooling water circulation mechanism for oxygen production, including a mounting frame, wherein a water circulation cooling component is movably connected to the front and rear sides of the bottom of the mounting frame via a pivot pin, the water circulation cooling component includes two mounting plates, the top of the two mounting plates on opposite sides are snapped into the mounting frame, and an air-cooling component is snapped into the opposite sides of the two mounting plates, the air-cooling component includes a ventilation shell, and the side of the ventilation shell near the mounting plate is snapped into the mounting plate.

[0007] Using the above technical solution: When cooling is required inside the oxygen generator housing, which consists of a mounting frame, mounting plate, and positioning plate, the user simultaneously starts water pump one and water pump two. Cooling water, cooled by cooling pipes installed in the two cooling shells, circulates within the water circulation cooling assembly. This cools the air around the cooling pipes, creating cold air. The user then starts the motor to drive the fan blades, blowing the cold air from the surface of the cooling pipes into the oxygen generator housing through the through-holes in the mounting plate, completing a dual-circulation heat dissipation process. When maintenance of the water circulation cooling assembly is required after prolonged use, the user removes the air-cooled assembly from the mounting plate, then moves the positioning plate and mounting plate away from the mounting frame via the pivot pins. The water circulation cooling assembly is then removed from the mounting plate surface, allowing for gradual disassembly of the components for inspection, maintenance, or replacement.

[0008] The present invention is further configured such that the two water storage shells and the two cooling shells are movably connected at their opposite ends away from the mounting plate by a pivot pin; a water pump 1 and a water pump 2 are respectively snapped into the top and bottom of the two water storage shells and the two cooling shells; a cooling pipe is connected between the bottom of the two cooling shells and the water pump 1; a connecting pipe is connected to the top of the two water storage shells and the water pump 2; and a filter shell is snapped into the opposite side of the two connecting pipes.

[0009] The above technical solution employs a pin-connected design that allows the water storage tank and cooling tank to be opened and closed. When closed, the pin is locked to ensure the airtightness of the cooling water circulation and prevent leakage. When opened, scale and impurities inside the tank can be cleaned directly without disassembling the entire pipeline, improving maintenance convenience. Pump 1 provides power for the cooling circulation from the cooling tank to the cooling pipe to the water storage tank. The cooled water directly exchanges heat with the air inside the oxygen generator through the cooling pipe, quickly reducing the temperature of the compartment formed by the mounting bracket, mounting plate, and positioning plate, while providing a low-temperature air source for air cooling. Pump 2 drives the cooling water in the filtration circulation from the water storage tank to the connecting pipe to the filter tank to the cooling tank. The filter tank, together with internal filter screens 1, 2, and 3, intercepts impurities in the circulating water, preventing blockage of the cooling pipe or pump 1 or pump 2, and ensuring that the cooling water always maintains efficient cooling capacity.

[0010] The present invention is further configured such that positioning frames are slidably connected to the inner cavities of the two water storage shells and the two cooling shells on the side near the mounting plate, and the side of the positioning frame near the mounting plate is engaged with the mounting plate.

[0011] The above technical solution is adopted: the water storage tank, cooling tank and mounting plate are firmly connected by the positioning frame to prevent the water circulation cooling components from shifting when they are working, and to ensure that the positions of the cooling pipe, cooling tank and oxygen generator inside will not shift.

[0012] The present invention is further configured such that, from left to right, filter screen one, filter screen two, and filter screen three are fixedly installed in the inner cavity of the filter shell, and the materials of filter screen one, filter screen two, and filter screen three are stainless steel filter screen, polypropylene filter screen, and nylon filter screen, respectively.

[0013] The above technical solution employs a three-layer gradient filtration structure: a stainless steel filter screen first intercepts large particles of impurities, a polypropylene filter screen filters medium-sized particles of impurities, and a nylon filter screen captures fine suspended matter. This triple filtration ensures the cleanliness of the circulating water, prevents impurities from clogging key components such as cooling pipes and water pumps, and guarantees continuous and stable water circulation and heat dissipation.

[0014] The present invention is further configured such that a motor is fixedly installed on the side of the ventilation housing away from the mounting plate, and the output end of the motor extends through the inner cavity of the ventilation housing and is fixedly installed with fan blades.

[0015] The above technical solution is adopted: the fan blades are driven by a motor to rotate at high speed, generating a directional airflow. The low-temperature air on the surface of the cooling pipe is blown into the oxygen generator through the through holes of the mounting plate, accelerating the air circulation inside the machine. This forms a dual heat dissipation mode of water cooling and air cooling circulation with the water circulation cooling components, which efficiently removes the heat generated by the compressor.

[0016] The present invention is further configured such that a positioning frame is fixedly installed on the side of the ventilation shell away from the mounting plate, and a dustproof mesh is fixedly installed in the inner cavity of the positioning frame.

[0017] The above technical solution is adopted to prevent external dust and debris from entering the ventilation shell and oxygen generator through the dustproof net, thereby avoiding dust from adhering to the fan blades, cooling pipes or compressor surface, which would lead to reduced heat dissipation efficiency and component wear, ensuring smooth air intake of the air-cooled components and maintaining the efficient operation of dual-cycle heat dissipation.

[0018] The present invention is further configured such that positioning rods are slidably connected to both sides of the ventilation shell, and the side of the positioning rod closest to the mounting plate is engaged with the mounting plate.

[0019] The above technical solution is adopted: the connection position between the ventilation shell and the mounting plate is quickly locked by the positioning rod to prevent the air-cooling component from shifting during use, ensuring that the airflow generated by the fan blades is accurately blown into the oxygen generator through the through hole. In addition, the sliding design of the positioning rod facilitates quick disassembly and assembly. During maintenance, the ventilation shell can be removed by pulling out the positioning rod without disassembling other parts, thus improving the maintenance efficiency of the air-cooling component.

[0020] The present invention is further configured such that both sides of the mounting bracket are movably connected to positioning plates via pivot pins, and the opposite sides of the two positioning plates are engaged with the mounting plate.

[0021] The above technical solution involves connecting the positioning plate, mounting plate, and mounting bracket to form a closed oxygen generator casing, creating a relatively sealed heat dissipation space. This prevents cold air leakage and ensures that the cold air generated by the dual-cycle cooling system is concentrated on the internal components, improving heat dissipation efficiency. The pin connection between the positioning plate and the mounting bracket facilitates opening and closing. During maintenance, opening the positioning plate allows access to the internal water circulation cooling components and subsequent installed compressors, without disassembling the entire casing, providing convenient operating space for component maintenance.

[0022] In summary, this utility model has the following beneficial effects: 1. When it is necessary to cool the inside of the oxygen generator housing, which consists of a mounting frame, mounting plate, and positioning plate, the user should simultaneously start water pump one and water pump two. The cooling water, which is cooled by the cooling pipes installed in the two cooling shells, circulates within the water circulation cooling assembly. After cooling the air around the cooling pipes to form cold air, the user should start the motor to drive the fan blades and blow the cold air from the surface of the cooling pipes into the inside of the oxygen generator housing through the through holes in the mounting plate, thus completing the dual-circulation heat dissipation. 2. When the water circulation cooling component needs maintenance after long-term use, the user should remove the air-cooling component and the mounting plate, then move the positioning plate and the mounting plate away from the mounting bracket in sequence via the pivot pin. Then, remove the water circulation cooling component from the surface of the mounting plate. After that, the structure in the water circulation cooling component can be gradually disassembled for inspection or maintenance and replacement. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A cooling water circulation mechanism for oxygen production includes a mounting frame 1. The front and rear sides of the bottom of the mounting frame 1 are movably connected to a water circulation cooling assembly 2 via pivot pins. The water circulation cooling assembly 2 includes two mounting plates 201, and the top of the two mounting plates 201 on opposite sides are snapped together with the mounting frame 1.

[0027] Furthermore, the two water storage shells 202 and the two cooling shells 203 are movably connected at their opposite ends away from the mounting plate 201 via a pivot pin. The top and bottom of the two water storage shells 202 and the two cooling shells 203 are respectively secured with a water pump 1 204 and a water pump 205. A cooling pipe 206 connects the bottom of the two cooling shells 203 and the water pump 1 204. The tops of the two water storage shells 202 and the water pump 2 205 are connected with a connecting pipe 207. A filter shell 208 is secured between the opposite sides of the two connecting pipes 207.

[0028] Furthermore, positioning frames 209 are slidably connected to the inner cavities of the two water storage shells 202 and the two cooling shells 203 on the side near the mounting plate 201, and the side of the positioning frame 209 near the mounting plate 201 is engaged with the mounting plate 201.

[0029] Furthermore, the inner cavity of the filter housing 208 is fixedly installed with filter screen 1 210, filter screen 211 and filter screen 3 212 from right to left. The materials of filter screen 1 210, filter screen 211 and filter screen 3 212 are stainless steel filter screen, polypropylene filter screen and nylon filter screen, respectively.

[0030] Brief description of usage: When cooling is required inside the oxygen generator housing consisting of mounting bracket 1, mounting plate 201, and positioning plate 4, the user, before the mounting plate 201 forms the housing with the mounting bracket 1 and positioning plate 4, engages the water circulation cooling assembly 2 with the inner cavity of the two mounting plates 201, and activates the cooling pipes in the cooling chamber composed of two cooling shells 203 to cool the internal cooling water. After cooling is complete, simultaneously activate water pump 1 204 and water pump 205 to circulate the cooling water within the cooling structure composed of cooling pipe 206, water storage shell 202, connecting pipe 207, filter shell 208, and cooling shell 203. After cooling the air around the cooling pipe 206 to form cold air, the air-cooling component 3 is installed on the mounting plate 201 and positioned by the positioning rod 306. Then, the user starts the motor 302 to drive the fan blades 303, blowing the cold air on the surface of the cooling pipe 206 into the oxygen generator shell composed of the mounting bracket 1, mounting plate 201 and positioning plate 4 through the through hole in the mounting plate 201, thus completing the dual-cycle heat dissipation. The water storage shell 202 and the cooling shell 203 are designed to be openable and closable through the shaft pin connection. When closed, the locking and fixing ensures the sealing of the cooling water circulation and avoids leakage. When opened, the scale and impurities inside the shell can be cleaned directly without disassembly. The overall piping system is designed to improve maintenance convenience. Pump 204 provides power for the cooling circulation from cooling shell 203 to cooling pipe 206 to water tank 202. The cooled water directly exchanges heat with the air inside the oxygen generator via cooling pipe 206, rapidly reducing the temperature of the compartment formed by mounting bracket 1, mounting plate 201, and positioning plate 4, while simultaneously providing a low-temperature air source for air cooling. Pump 205 drives the cooling water in a filtration circulation from water tank 202 to connecting pipe 207, to filter shell 208, and back to cooling shell 203. Filter shell 208, in conjunction with internal filters 210, 211, and 212, intercepts impurities in the circulating water, preventing blockages. Cooling pipe 206, or water pump 1 204, or water pump 2 205, ensure that the cooling water always maintains efficient cooling capacity; the positioning bracket 209 securely connects the water storage tank 202, cooling tank 203, and mounting plate 201 to prevent displacement of the water circulation cooling assembly 2 during operation, and ensure that the cooling pipe 206, cooling tank 203, and the position inside the oxygen generator do not shift; through a three-layer gradient filtration structure, the stainless steel filter screen first intercepts large particle impurities, the polypropylene filter screen filters medium-sized particle impurities, and the nylon filter screen captures fine suspended matter. The triple filtration ensures the cleanliness of the circulating water, prevents impurities from clogging key components such as the cooling pipe 206 and water pump, and ensures continuous and stable water circulation heat dissipation.

[0031] Example 2: refer to Figure 1 , Figure 2 and Figure 4A cooling water circulation mechanism for oxygen production includes two mounting plates 201. Each mounting plate 201 has an air-cooling component 3 snapped onto its opposite side. The air-cooling component 3 includes a ventilation shell 301, with the side of the ventilation shell 301 closest to the mounting plate 201 snapped onto the mounting plate 201.

[0032] Furthermore, a positioning frame 304 is fixedly installed on the side of the ventilation shell 301 away from the mounting plate 201, and a dustproof mesh 305 is fixedly installed in the inner cavity of the positioning frame 304.

[0033] Furthermore, both sides of the ventilation housing 301 are slidably connected with positioning rods 306, and the side of the positioning rods 306 near the mounting plate 201 is engaged with the mounting plate 201.

[0034] Furthermore, the front and rear sides of the mounting bracket 1 are movably connected to positioning plates 4 via pivot pins, and the opposite sides of the two positioning plates 4 are engaged with the mounting plate 201.

[0035] Brief description of usage: When maintenance of the water circulation cooling component 2 is required after prolonged use, the user should turn off the air cooling component 3, remove it from the mounting plate 201, then unplug the positioning plate 4 from the mounting plate 201, and move the mounting plate 201 away from the mounting bracket 1 via the shaft pin. Then, remove the water circulation cooling component 2 from the surface of the mounting plate 201. Subsequently, the cooling pipe 206, water pump 1 204, filter shell 208, connecting pipe 207, and water pump 205 can be gradually disassembled for inspection or maintenance / replacement. If necessary, the internal parts of the two water storage shells 202 and the two cooling shells 203 can be inspected. During cleaning, after rotating the positioning ring to the designated position, the positioning frame 209 is disengaged from the water storage shell 202 and cooling shell 203. The interior of the water storage shell 202 and cooling shell 203 can then be cleaned. After cleaning or inspection, the structure is reset and re-engaged with the mounting plate 201. The motor 302 drives the fan blades 303 to rotate at high speed, generating a directional airflow. This airflow blows the low-temperature air from the surface of the cooling pipe 206 into the oxygen generator through the through-holes in the mounting plate 201, accelerating air circulation within the machine. This forms a dual heat dissipation mode of water cooling and air cooling circulation with the water circulation cooling component 2, efficiently removing air from the compressor. The generated heat is prevented from entering the ventilation housing 301 and the oxygen generator through the dustproof mesh 305, which blocks external dust and debris. This prevents dust from adhering to the fan blades 303, cooling pipes 206, or compressor surface, thus avoiding reduced heat dissipation efficiency and component wear. It also ensures smooth airflow into the air-cooled assembly 3 and maintains efficient dual-cycle cooling operation. The positioning rod 306 quickly locks the connection between the ventilation housing 301 and the mounting plate 201, preventing displacement of the air-cooled assembly 3 during use. This ensures that the airflow generated by the fan blades 303 is accurately blown into the oxygen generator through the through-holes. The sliding design of the positioning rod 306 facilitates quick disassembly and assembly, and allows it to be pulled out for maintenance. The ventilation shell 301 can be removed by positioning rod 306 without disassembling other parts, improving the maintenance efficiency of the air-cooled component 3. The positioning plate 4 is connected to the mounting plate 201 and mounting bracket 1 to form a closed oxygen generator shell, creating a relatively sealed heat dissipation space to prevent cold air leakage and ensure that the cold air generated by the dual-cycle heat dissipation is concentrated on the internal components, improving heat dissipation efficiency. The pin connection between the positioning plate 4 and the mounting bracket 1 facilitates opening and closing. During maintenance, opening the positioning plate 4 allows access to the internal water circulation cooling component 2 and subsequent installed components such as the compressor, without disassembling the entire shell, providing convenient operating space for component maintenance.

[0036] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0037] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
