Description

Technical Field

[0001] This utility model relates to the field of compressors, and in particular to a gas replenishment device for a jet-induced enthalpy-enhancing compressor. Background Technology

[0002] Injection gas into a jet-type enthalpy compressor refers to a method of increasing enthalpy by injecting high-pressure gas into the intermediate pipeline of the compressor to increase the kinetic energy of the refrigerant flow and the compressor's cooling capacity. The main function of injection gas is to improve the compressor's cooling efficiency and cooling capacity, especially in low-temperature environments, where it can significantly enhance heating capacity.

[0003] The gas supply device for a jet-induced enthalpy-enhancing compressor mainly consists of a compressor as the driving source and a pipeline structure for gas conduction. Chinese Patent Publication No. CN 212457509 U describes a "gas supply pipeline structure for a jet-induced enthalpy-enhancing compressor," which includes a buffer device and pipe clamps. The buffer device buffers the rapidly flowing airflow to reduce the impact force of the gas on the pipeline; the pipe clamps fix the buffer device and also provide some shock absorption, resulting in stronger protection for the pipeline.

[0004] However, the following defects and shortcomings still exist in the application implementation process: Its protective effect on bends is relatively weak. Therefore, when the airflow passes through the bends of the entire pipeline system, it will have a certain impact on the pipeline, resulting in a shorter service life for the bends.

[0005] Therefore, it is necessary to provide a new jet-induced enthalpy-enhancing compressor gas supply device to solve the above-mentioned technical problems. Utility Model Content

[0013] Compared with related technologies, the jet enthalpy-enhancing compressor gas replenishment device provided by this utility model has the following beneficial effects: This utility model provides a jet enthalpy-enhancing compressor air supply device in which a connecting pipe is added between the air inlet of the bend and the straight pipe. The connecting pipe has a spiral plate inside, so when the airflow enters the spiral plate area, the spiral plate can be used to buffer the airflow, thereby reducing the impact of the airflow on the bend.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 6 The present invention provides a jet enthalpy-enhancing compressor gas supply device, which includes a bent pipe 1 and a straight pipe 2 located at the air inlet of the bent pipe 1. A connecting pipe 3 is flexibly installed between the bend 1 and the straight pipe 2, and a spiral plate 32 is fixed on the inner circumference of the connecting pipe 3. An auxiliary fixing bracket 5 is also fixed on the straight pipe 2, and the connecting pipe 3 is mounted on the auxiliary fixing bracket 5.

[0022] It should be noted that in this device, the straight pipe 2 is located at the air inlet of the bend pipe 1, so the airflow passes through the straight pipe 2 and then enters the interior of the bend pipe 1. The connecting pipe 3 is located between the bend 1 and the straight pipe 2. Therefore, when the airflow enters the bend 1, it will pass through the connecting pipe 3. Inside the connecting pipe 3, there is a spiral plate 32, which has a certain buffering effect on the airflow. Therefore, it can reduce the airflow velocity and reduce the impact force on the bend 1 after the airflow enters the bend 1, thereby reducing the erosion of the pipe by the airflow and improving the service life of the pipe. The connecting pipe 3 is flexibly installed between the bend 1 and the straight pipe 2, so that the connecting pipe 3 has a certain elastic floating amount, thereby further improving the buffering effect on the airflow. The auxiliary fixing bracket 5 is fixed on the straight pipe 2, and the connecting pipe 3 is also mounted on the auxiliary fixing bracket 5. Therefore, the auxiliary fixing bracket 5 can support the connecting pipe 3 to improve the stability of the connecting pipe 3, and will not affect the floating of the connecting pipe 3.

[0023] In the embodiments of this utility model, please refer to Figure 3 The inner circumference of the connecting tube 3 has symmetrical internal threads at a position away from the center. An inner fixing tube 31 is also threaded inside the connecting tube 3. The spiral plate 32 is welded and fixed to the inner circumference of the inner fixing tube 31.

[0024] It should be noted that the internal thread of the connecting tube 3 is connected to the internal fixing tube 31, and the spiral plate 32 is welded and fixed to the internal fixing tube 31. Therefore, the internal fixing tube 31 can be disassembled to facilitate the inspection and replacement of the spiral plate 32.

[0025] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 A rubber tube 4 is installed between the bend 1 and the connecting pipe 3, and between the straight pipe 2 and the connecting pipe 3. The rubber tube 4 is fixed to the bend 1 and the straight pipe 2 by bolts. A spring 41 is also installed and fixed inside the rubber tube 4.

[0026] It should be noted that: the rubber tube 4 is a pipe that connects the bend 1, the straight pipe 2 and the connecting pipe 3 to realize the connection of the pipes. The rubber tube 4 itself is a flexible pipe, so it has a certain degree of extensibility, which allows the connecting pipe 3 to have a certain amount of floating. At the same time, a spring 41 is also installed inside the rubber tube 4, which can further improve the pressure resistance of the rubber tube 4 and make the rubber tube 4 more stable.

[0027] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The auxiliary fixing bracket 5 includes a fixing ring 51, a positioning frame 52, a connecting plate 53, and a support roller 54; The fixing ring 51 is sleeved on the straight pipe 2 and welded to it. The positioning frame 52 is an inverted U-shape. The positioning frame 52 is sleeved on the outside of the connecting pipe 3 and does not contact the connecting pipe 3. The connecting plate 53 is bolted to the fixing ring 51 and the positioning frame 52. The support roller 54 is rotatably connected to the positioning frame 52. The support roller 54 and the positioning frame 52 form an arched closed frame. The connecting pipe 3 passes through the frame and is mounted on the support roller 54. A rubber sleeve 55 is sleeved on the outside of the support roller 54.

[0028] It should be noted that in the auxiliary fixing bracket 5, the fixing ring bracket 51 is fixed on the straight pipe 2 and connected to the positioning bracket 52 through the connecting plate 53 to position the positioning bracket 52. The positioning bracket 52 has multiple support rollers 54, and the connecting pipe 3 is mounted on the support rollers 54, which can support the connecting pipe 3 and further improve the stability of the connecting pipe 3. At the same time, the support rollers 54 can rotate without affecting the floating of the connecting pipe 3. The support roller 54 has a rubber sleeve 55 on its surface, which can reduce damage to the surface of the connecting pipe 3 and also reduce noise.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
