Technical Field
[0001] This utility model relates to the field of heat exchange component technology, and in particular to an oxygen compression stage cooling heat exchange component. Background Technology
[0002] Oxygen generates heat during compression, and the cooling heat exchange components are responsible for lowering the oxygen temperature to ensure normal equipment operation and improve system efficiency.
[0003] As a strong oxidizing gas, oxygen's safety during compression is paramount. Old coolers may pose potential safety hazards, such as leaks and overheating, which not only affect the safe operation of the equipment itself but may also cause serious safety accidents such as fires and explosions, posing risks to personnel and the surrounding environment. Therefore, regular maintenance and repair are necessary. However, the disassembly and assembly of sealed heat exchanger components is cumbersome and time-consuming due to the large number of bolts used for fastening. To address this issue, we propose an oxygen compression stage cooling heat exchange component to solve the existing problems. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an oxygen compression stage cooling heat exchange component.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxygen compression stage cooling heat exchange component, comprising an annular seat, a closed cover, a housing, a spiral plate, a travel plate, and a motor. The housing contains a spiral plate forming a spiral channel with the housing. A closed cover is located at one end of the housing. An annular seat is fitted onto the outer side of one end of the housing. Screws arranged in a circular array are rotatably mounted on the outer side of the housing. Nuts threaded onto the outer wall of the screws are embedded within the travel plate. Driven gears located inside the annular seat are fitted onto the outer wall of each screw. A motor is located at one end of the housing, and a drive gear is located at one end of the motor. A rotating ring is rotatably mounted on the inner wall of the annular seat, and a gear ring meshing with the drive gear and the driven gear is located on the inner wall of the rotating ring.
[0006] When using one of the oxygen compression interstage cooling heat exchange components in this solution, during the oxygen compression process, oxygen is input into the spiral channel through the inlet pipe, and the heat exchange fluid is transported to the spiral plate through the water inlet pipe. The oxygen flows along the spiral channel formed between the spiral plate and the shell, forming a spiral flow. During the spiral flow, heat is transferred from one fluid to another. This flow path increases the contact area between the fluid and the plate, accelerating the heat transfer rate. Compared with traditional heat exchangers, the spiral plate heat exchanger has a more compact design, saves space, has a large heat transfer surface area, and enhances heat transfer efficiency. The heat-exchanged fluid is output through the water outlet, and the heat-exchanged oxygen is further transported through the air outlet.
[0007] Preferably, a hydraulic rod is fixed to one end of the housing, and a pressure plate is provided at the lower end of the hydraulic rod directly above the drive gear. When the hydraulic rod is in operation, it drives the pressure plate to press against the upper end of the drive gear. When the drive gear is not in use, the drive gear is locked.
[0008] Preferably, a connecting rod arranged in a circular array is provided between the ring seat and the housing, and a base is provided at the lower end of the housing. The ring seat is fixed to the housing by the connecting rods, thereby supporting the ring seat, and the ring seat is firmly attached to the outer side of one end.
[0009] Preferably, the outer wall of the housing is provided with guide rails arranged in a circular array, one end of the travel plate is connected to the closing cover, and the lower end of the travel plate is provided with a slider that is slidably sleeved on the outer wall of the guide rails. The slider slides on the outer wall of the guide rails, and the travel plate is slidably supported by the slider as it moves outside the housing.
[0010] Preferably, a sealing gasket is provided at one end of the closed cover, and the sealing gasket is in contact with the outer wall of one side of the spiral plate and the outer wall of the shell opening. When the closed cover is in contact with the shell opening and the outer wall of the spiral plate, the sealing gasket improves the sealing performance at the contact point.
[0011] Preferably, one end of the spiral plate is provided with a water inlet pipe penetrating the shell, and the other end of the spiral plate is provided with a water outlet pipe penetrating the shell. The cooling medium is transported into the spiral plate through the water inlet pipe and exited from the spiral plate through the water outlet pipe.
[0012] Preferably, an outlet pipe is connected to one end of the housing, and an inlet pipe is connected to the center of one end of the housing. Oxygen is input into the spiral channel through the inlet pipe and output from the spiral channel through the outlet pipe.
[0013] Preferably, the outer walls of the water inlet pipe, air outlet pipe, and air inlet pipe are all fitted with flanges, and each flange has an installation hole inside. The water inlet pipe, air outlet pipe, and air inlet pipe are connected to external pipelines through flanges, and fasteners are installed through the installation holes.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. In this utility model, the heat exchange medium is transported through a spiral plate. The medium flowing inside the shell does not directly contact the inner wall of the shell. The spiral channel formed between the spiral plate and the shell transports the oxygen. The oxygen is transported in a spiral manner. During the transport process, the spiral channel continuously impacts the outer wall of the spiral plate, thereby improving the heat exchange efficiency when the spiral plate and oxygen exchange heat.
[0016] 2. At the same time, a closing cover that can be easily opened and closed is provided on one side of the housing, so that the inside of the housing is directly open, making maintenance and repair of the inside of the housing easy and convenient. Attached Figure Description

[0023] 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.
[0024] like Figures 1-5 As shown, the present invention proposes an oxygen compression stage cooling heat exchange component, including a ring seat 1, a closed cover 6, a shell 7, a spiral plate 9, a stroke plate 11 and a motor 20. The spiral plate 9 is provided inside the shell 7, and a spiral channel is formed between the spiral plate 9 and the shell 7. The closed cover 6 is provided at one end of the shell 7, and the ring seat 1 is sleeved on the outer side of one end of the shell 7.
[0025] A connecting rod 17 arranged in a ring array is provided between the ring seat 1 and the housing 7, and a base 5 is provided at the lower end of the housing 7;
[0026] One end of the spiral plate 9 is provided with an inlet pipe 2 that penetrates the shell 7, and the other end of the spiral plate 9 is provided with an outlet pipe 13 that penetrates one end of the shell 7.
[0027] An air outlet pipe 3 is connected to one end of the housing 7, and an air inlet pipe 12 is connected to the center of one end of the housing 7.
[0028] The outer walls of the water inlet pipe 2, the air outlet pipe 3, the water outlet pipe 13, and the air inlet pipe 12 are all fitted with flanges 4, and each flange 4 has an installation hole inside.
[0029] Based on the implementation steps of Example 1: Water inlet pipe 2, air outlet pipe 3, water outlet pipe 13 and air inlet pipe 12 are connected to external pipes through flange 4. The insertion bolts are rotated inside the mounting hole to fix the external pipes of water inlet pipe 2, air outlet pipe 3, water outlet pipe 13 and air inlet pipe 12. Air inlet pipe 12 and water inlet pipe 2 respectively transport oxygen and cooling fluid. The cooling fluid is transported to spiral plate 9. Oxygen flows inside the spiral channel. The cooling medium exchanges heat with oxygen. The oxygen compression process achieves efficient heat exchange.
[0030] like Figures 1-5 As shown, compared with Embodiment 1, the oxygen compression stage cooling heat exchange component proposed in this utility model further includes: screws 8 arranged in a ring array are rotatably mounted on the outer side of the housing 7; nuts 19 threaded to the outer wall of the screws 8 are embedded in the stroke plate 11; driven gears 14 located inside the ring seat 1 are sleeved on the outer wall of each screw 8; a motor 20 is provided at one end of the housing 7; a drive gear 23 is provided at one end of the motor 20; a rotating ring 15 is rotatably mounted on the inner wall of the ring seat 1; and a gear ring 16 meshing with the drive gear 23 and the driven gear 14 is provided on the inner wall of the rotating ring 15.
[0031] A hydraulic rod 21 is fixed at one end of the housing 7, and a pressure plate 22 located directly above the drive gear 23 is provided at the lower end of the hydraulic rod 21.
[0032] The outer wall of the housing 7 is provided with guide rails 18 arranged in a ring array. One end of the stroke plate 11 is connected to the closing cover 6. The lower end of the stroke plate 11 is provided with a slider that is slidably sleeved on the outer wall of the guide rail 18.
[0033] A sealing gasket 10 is provided at one end of the closed cover 6, and the sealing gasket 10 is in contact with the outer wall of one side of the spiral plate 9 and the outer wall of the opening of the shell 7.
[0034] In this embodiment, after the heat exchange component is used, the motor 20 operates and the output end rotates, driving the drive gear 23 to rotate. Because the gear ring 16 rotates inside the ring seat 1 through the rotating ring 15, the drive gear 23 pushes the gear ring 16, causing the rotating ring 15 to rotate. The gear ring 16 pushes the driven gear 14, thereby driving the screw 8 to rotate. Because the slider slides and guides the stroke plate 11, the nut 19 is also slides and guided. The nut 19 is pushed by the rotational power of the screw 8, thereby driving the closing cover 6 to move, and the inside of the housing 7 is opened, thus enabling convenient inspection and maintenance of the inside of the housing 7.
[0035] After maintenance, the heat exchanger assembly closes the opening through the closing cover 6. Because multiple travel plates 11 apply a pulling force to the closing cover 6 at the same time, the closing cover 6 is supported at multiple points at the closing point of the shell 7, making the closing cover 6 stable. The sealing gasket 10 is squeezed and effectively fits against the opening of the shell 7 on the outer wall of the spiral plate 9.
[0036] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
