Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor structure. Background Art

[0002] When the compressor is running, the bearings generate a lot of heat due to high-speed rotation, and lubricating oil is needed for lubrication and cooling. However, the lubricating oil is circulated. As the number of cycles increases, the temperature of the lubricating oil gradually rises. When the temperature of the lubricating oil is too high, it will affect the viscosity of the lubricating oil and the lubrication effect, reducing the bearing capacity of the bearing. At the same time, because the oil temperature is too high, the lubricating oil cannot cool the bearing. Therefore, it is necessary to cool the lubricating oil so that the lubricating oil is kept at a suitable temperature for use and to play the best lubrication and cooling role.

[0003] When the centrifugal refrigeration unit is running, the high-power centrifugal compressor is running. Due to the large suction force of the air intake port, it is easy to suck the gas-liquid mixed gas in the evaporator into the compressor impeller, resulting in the phenomenon of air intake with liquid. The small droplets of liquid in the air intake will continuously impact the high-speed rotating impeller, which is easy to damage the impeller. For this reason, a gas-liquid filter and a liquid baffle are set in the conventional evaporator shell near the shell and tube air intake port to separate the small droplets of refrigerant in the mixed gas to prevent the impeller from being damaged by the air intake with liquid. However, since the temperature at the air intake port of the evaporator is relatively low, according to the inherent characteristics of the refrigerant, the lower the temperature, the easier it is for the refrigerant to turn into a liquid state; therefore, although a gas-liquid filter and a liquid baffle are set near the air intake port of the evaporator, a small amount of air intake with liquid is inevitable. In this case, can we also use the inherent characteristics of the refrigerant to set a heating device at the air intake port to appropriately heat the air intake mixed gas, so that the refrigerant droplets in the mixed gas directly absorb heat and turn into a gas state, eliminating the phenomenon of air intake with liquid.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0037] According to an embodiment of the present utility model, a compressor structure is provided. Figures 1 to 7, compressor component 1; an exhaust pipeline 2, the exhaust pipeline 2 is connected to the exhaust port 11 of the compressor component 1; an intake pipeline 3, the intake pipeline 3 is connected to the air inlet 12 of the compressor component 1; a heat exchange component 4, the heat exchange component 4 has a heat exchange cavity 41, the heat exchange cavity 41 is communicated with the exhaust pipeline 2, and the heat exchange cavity 41 is communicated with the air inlet 12 of the compressor component 1; a filtering structure 5, the filtering structure 5 is arranged in the heat exchange cavity 41, and the filtering structure 5 is used to filter the liquid in the fluid; a heating structure 6, including an oil tank 61, the oil tank 61 is connected to the oil supply system of the compressor component 1, and the heating structure 6 is arranged corresponding to the filtering structure 5, so that the fluid discharged from the exhaust port 11 of the compressor component 1 passes through the filtering structure 5 and the heating structure 6 and enters the air inlet 12 of the compressor component 1.

[0038] With the above arrangement, in the compressor structure of this embodiment, a heating structure 6 is provided in the heat exchange component 4, and the suction of the compressor component 1 is used to cool the lubricating oil in the oil tank 61, and at the same time, the high temperature of the lubricating oil in the oil tank 61 is used to heat the suction air to eliminate small droplets. The resulting effect can not only effectively cool the lubricating oil, ensure that the lubricating oil is maintained at a suitable temperature for operation, ensure the viscosity of the lubricating oil, increase the bearing capacity of the bearing and ensure the effect of the lubricating oil on cooling the bearing; but also, it can eliminate small droplets of refrigerant in the suction of the compressor component 1, eliminate the phenomenon of suction carrying liquid, protect the impeller, ensure the long-term and reliable operation of the unit, and solve the technical problem in the related technology that liquid easily enters the compressor during suction.

[0039] In the compressor structure of this embodiment, the heating structure 6 includes: an oil tank 61, the oil tank 61 has a flow cavity 611, the oil tank 61 includes an oil return port 612 and an oil outlet 613 connected to the flow cavity 611, and the oil return port 612 and the oil outlet 613 are both connected to the oil supply system 13 of the compressor component 1. In this way, when the oil flows in the flow cavity 611, heat exchange can be completed, thereby improving the heating efficiency.

[0040] In order to ensure the working effect, in this embodiment, the heating structure 6 includes a heater for heating the oil tank 61. In this way, when the oil temperature in the oil tank 61 is low, the oil is heated by the heater, which can ensure the normal oil supply of the system and the effect of removing droplets.

[0041] See also Figure 2 , Figure 3 In the compressor structure of this embodiment, the oil tank 61 is provided with an air hole 614, and the air hole 614 is set through the oil tank 61. In this way, the fluid discharged from the exhaust port 11 of the compressor component 1 passes through the air hole 614, exchanges heat with the oil in the oil tank 61, and then enters the air inlet 12 of the compressor component 1, so that the heat exchange effect is carried out in the flow of air, thereby improving the circulation efficiency of the fluid.

[0042] To improve the heat exchange efficiency, see Figure 2 , Figure 3 In the compressor structure of this embodiment, there are multiple air holes 614, and the multiple air holes 614 are arranged at intervals.

[0043] See also Figure 2 In the compressor structure of this embodiment, the oil tank 61 includes: an oil return pipe 615, one end of which is connected to the oil return port 612, and the other end of which is connected to the flow chamber 611; an oil outlet pipe 616, one end of which is connected to the oil outlet port 613, and the other end of which is connected to the flow chamber 611; and the oil outlet pipe 616 is located above the oil return pipe 615. In this way, when the oil flows in the oil tank 61, the fluid flows from bottom to top, which increases the flow stroke of the oil, increases the heat exchange time, and makes the heat exchange more sufficient.

[0044] In the compressor structure of this embodiment, a mounting bracket 42 is provided in the heat exchange cavity 41, a mounting cavity 412 is provided in the mounting bracket 42, a filtering structure 5 is provided in the mounting cavity 412, a heating structure 6 is connected to the mounting bracket 42, and an oil tank 61 is located outside the mounting cavity 412. In this way, before the fluid passes through the heating structure 6, the filtering structure 5 is used to filter the droplets in the fluid first, and the fluid is filtered in the sealed mounting cavity 412, thereby improving the filtering efficiency and thus improving the effect of filtering the droplets.

[0045] See also Figure 4 In the compressor structure of this embodiment, the mounting bracket 42 includes: a first bracket 421, the first bracket 421 is fixed on the inner wall of the heat exchange chamber 41, and the first bracket 421 is connected to the filter structure 5; a second bracket 422, the second bracket 422 is fixed on the inner wall of the heat exchange chamber 41, and the second bracket 422 is connected to the filter structure 5; the second bracket 422 is arranged opposite to the first bracket 421; a mounting bracket 423, and the oil tank 61 is arranged on the mounting bracket 423; one end of the mounting bracket 423 is connected to the first bracket 421, and the other end of the mounting bracket 423 is connected to the second bracket 422. In this way, the mounting bracket 42 is arranged to fix the filter structure 5 and the oil tank 61 synchronously, thereby simplifying the structure.

[0046] In the compressor structure of this embodiment, the mounting frame 423 includes a protrusion 4231 for stopping the oil tank 61 and a mounting portion 4232 for carrying the oil tank 61. One end of the protrusion 4231 is connected to the mounting frame 423, and the other end of the protrusion 4231 is connected to the second bracket 422. The height of the protrusion 4231 in the horizontal direction gradually increases in the direction away from the mounting portion 4232. In this way, by setting the protrusion 4231, the oil tank 61 is limited, thereby ensuring the installation position of the oil tank 61 and ensuring the circulation and heat exchange of the fluid.

[0047] In the compressor structure of this embodiment, the first bracket 421 includes a receiving portion 4211 located below the mounting bracket 423 and a stopper 4212 located above the mounting bracket 423. The stopper 4212 is an arc-shaped structure; the stopper 4212 is used to abut against the oil tank 61. In this way, by setting the stopper 4212, the oil tank 61 is limited, thereby ensuring the installation position of the oil tank 61 and ensuring the circulation and heat exchange of the fluid.

[0048] In the compressor structure of the present embodiment, the oil tank 61 includes: a first oil pipe 617, the first oil pipe 617 is arranged to pass through the heat exchange component 4, and the oil return port 612 is located on the first oil pipe 617; a second oil pipe 618, the second oil pipe 618 is arranged to pass through the heat exchange component 4, and the oil outlet 613 is located on the second oil pipe 618; wherein, the protrusion 4231 and the stop portion 4212 are respectively located on opposite sides of the oil tank 61, and the second oil pipe 618 is located on the side of the first oil pipe 617 away from the stop portion 4212. With the above arrangement, the raised portion 4231 abuts against the bottom of the oil tank 61, and the stop portion 4212 abuts against the middle of the oil tank 61, and the oil flows from the portion of the flow chamber 611 close to the stop portion 4212 to the portion of the flow chamber 611 close to the raised portion 4231. In this way, when the oil flows, it can only generate a force on the oil tank 61 to push the oil tank 61 to move toward the raised portion 4231, thereby avoiding the oil tank 61 and the stop portion 4212 from colliding with each other, thereby damaging the structure of the oil tank 61.

[0049] Specifically, the first bracket 421 and the second bracket 422 are respectively integrally formed structures, and the protruding portion 4231 and the stopper portion 4212 are formed by bending. The above arrangement can reduce the bent portion as much as possible.

[0050] In the compressor structure of this embodiment, the oil supply system 13 includes: an oil supply pipeline 131, which is connected to both the oil return port 612 and the oil outlet 613; an oil chamber 132, in which a bearing component 133 is arranged, and the bearing component 133 is connected to the rotor of the compressor component 1. In this way, the oil can achieve the functions of heating and lubrication, combining the performance of the heating structure 6 with the compressor structure, and improving the working efficiency of the compressor structure.

[0051] In the compressor structure of this embodiment, the compressor structure further includes: a heat exchange tube 7, which is arranged in the heat exchange component 4, and is located on the side of the filter structure 5 away from the heating structure 6, and has a refrigerant for heat exchange; a condenser 8, which is arranged on the exhaust pipeline 2, so that the fluid discharged from the exhaust port 11 of the compressor component 1 passes through the condenser 8 and then flows into the heat exchange component 4; a control valve 9 arranged in the exhaust pipeline 2, and the control valve 9 is used to control the flow rate of the fluid in the exhaust pipeline 2. In this way, the temperature of the fluid discharged from the compressor component 1 can be prevented from being too high.

[0052] Embodiment 1:

[0053] In the compressor structure of this embodiment, the oil tank 61 is built into the vicinity of the air intake port of the evaporator (i.e., the heat exchange component 4), such as Figure 1 As shown, the air suction of the compressor component 1 is used to cool the lubricating oil in the oil tank 61, and at the same time, the high temperature of the lubricating oil in the oil tank 61 is used to heat the suction air to eliminate small droplets. The resulting effect can not only effectively cool the lubricating oil, ensure that the lubricating oil is maintained at a suitable temperature for operation, ensure the viscosity of the lubricating oil, increase the bearing capacity of the bearing and ensure the effect of the lubricating oil on cooling the bearing; but also, it can eliminate small droplets of refrigerant in the suction air of the compressor component 1, eliminate the phenomenon of liquid in the suction air, protect the impeller, and ensure the long-term and reliable operation of the unit.

[0054] Embodiment 2:

[0055] The compressor structure of this embodiment is as follows Figure 2 , Figure 3 As shown, when the unit is running, the heat exchange tubes in the evaporator will exchange heat with the refrigerant liquid, and the refrigerant liquid soaking in the heat exchange tubes 7 will continue to boil. Part of the refrigerant will turn into gas after absorbing heat. At the same time, the centrifugal compressor component 1 is doing work, and the suction force is relatively large. Some small droplets of refrigerant that float up with the gas due to heat exchange boiling are also sucked toward the direction of the evaporator suction port by the compressor component 1 and enter the suction port of the compressor component 1. The small droplets hit the impeller of the compressor component 1 at high speed, which can easily damage the impeller. For this reason, a hot gas-liquid filter is provided to intercept the small droplets of refrigerant that float up with the gas, and most of the small droplets with larger volume can be blocked.

[0056] However, due to the inherent characteristics of the refrigerant, under a certain pressure and temperature environment, there will be some smaller droplets accompanying the gas, which is a state where gas and liquid coexist and can be transformed into each other; at this time, a simple gas-liquid filter or baffle structure cannot eliminate the small droplets; from the inherent characteristics of the refrigerant, we can also know that under the same conditions, increasing the temperature can transform the refrigerant from liquid to gas; therefore, it is only necessary to increase the temperature to eliminate the small droplets.

[0057] Therefore, when the air flow mixed with small droplets passes through the gas-liquid filter, it reaches the new built-in oil tank 61, which has a structure as shown in FIG. Figure 1As shown in the schematic diagram of the structure of the new built-in oil tank 61, the structure of the oil tank 61 is a hollow plate-shell structure, which can hold lubricating oil. The oil tank 61 body is penetrated with many air holes (heat exchange channels) for the suction gas to pass through the compressor component 1, and the suction gas passes through the holes from bottom to top; the oil tank 61 is provided with an oil return port and an oil outlet port; the oil return port is located at a side position at the lower part of the oil tank 61, and the oil outlet port is located at a side position at the upper part and diagonally opposite to the oil return port. The lubricating oil enters from the bottom and exits from the top, and the suction gas flows through the holes from the bottom to the top, so that the lubricating oil and the suction gas can fully exchange heat. When the small droplets in the air flow change from liquid to gas, a large amount of heat needs to be absorbed, which can significantly reduce the temperature of the lubricating oil. At the same time, the suction air flow velocity is large, which can accelerate the cooling speed of the lubricating oil; reducing the temperature of the lubricating oil allows the lubricating oil temperature to be at a suitable working temperature, ensures the viscosity of the lubricating oil, and improves the bearing bearing capacity. At the same time, the lubricating oil lubricates the bearing and is more likely to take away the heat generated by the bearing operation, effectively cooling the bearing and extending the service life of the bearing.

[0058] At the same time, the oil tank 61 is built into the vicinity of the air intake port of the evaporator, which can save space compared to the external oil tank 61 structure, make the unit structure compact, reduce the unit size, and improve the market competitiveness of the product.
