Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning compressors, and in particular to a compressor with a cooling capacity threshold. Background Art

[0002] During grain storage, maintaining a suitable temperature is crucial to prevent grain deterioration and ensure its quality. The environmental conditions of granaries are complex and changeable, especially in seasons with high temperatures. How to effectively control the temperature in granaries becomes a major challenge. In order to achieve more efficient and accurate temperature control management, traditional granary air-conditioning systems generally set up a compressor with a cooling threshold function, which can automatically adjust the operating state when the preset cooling threshold is reached to improve energy efficiency and reduce unnecessary energy consumption. The specific principle is based on the PID (proportional-integral-differential) control algorithm, which collects data through temperature sensors installed at multiple locations inside and outside the granary, and calculates the required cooling capacity after processing by the controller. Subsequently, the compressor speed and the opening of the electronic expansion valve are adjusted according to the calculation result to change the refrigerant flow, thereby achieving precise control of the temperature in the warehouse.

[0003] However, in the prior art, this type of air-conditioning compressor generally adopts a scroll structure with a sealed structure inside.

[0033] Reference Figure 1-Figure 8A compressor with a cooling capacity threshold comprises a shell 1, a base 11 is installed at the bottom of the shell 1, a mounting hole 110 is opened on the surface of the base 11, an air outlet 12 is arranged on the top side of the shell 1, a refrigerant inlet 15 is arranged on the side wall of the shell 1, a driving member 14 is arranged inside the shell 1, and a rotating shaft 13 is connected and installed at one end of the driving member 14, and also comprises: a cavity 3, which is opened in the inner wall of the shell 1; a rotatable eccentric wheel 24, which is arranged in the cavity 3, and one end of which is connected to the rotating shaft 13 through a transmission member; symmetrically distributed air bags b58, which are arranged in the base 11; when the eccentric wheel 24 rotates, the bottom sound-absorbing liquid pre-stored in the cavity 3 is extracted by the extraction member, and then sprayed obliquely upward to accelerate the flow of the sound-absorbing liquid, and when the eccentric wheel 24 rotates ninety degrees clockwise, the air bag b58 is expanded to prevent the bottom installation part of the compressor from loosening and displacement when the compressor is in working state.

[0034] In the prior art, storage management of granaries is a very important link. Especially in high temperature seasons, the grain in the granary needs to be cooled to prevent it from spoiling. Generally, an air-conditioning system is set up, and the indoor temperature data is collected by sensors. The required cooling capacity is calculated after processing by the controller, and then the compressor in the air-conditioning system is used to deliver the required amount of refrigerant, which saves costs and accurately controls the temperature in the granary. Therefore, a compressor with a cooling capacity threshold is developed. However, this type of compressor, especially used in air-conditioning systems, generally adopts a scroll structure, because its interior is sealed, and it is easy to cause the internal parts to move during the movement. It is easy to generate heat, resulting in poor heat dissipation effect, and the noise generated by the operation of the compressor affects the working environment. In the scheme, a cavity 3 is provided on the inner wall of the shell 1, and the inside of the cavity 3 is filled with sound-absorbing liquid, so as to absorb and reduce the noise generated by the operation of the mechanical parts inside the shell 1. At the same time, a layer of protection is provided on the inner wall of the shell 1 to facilitate the conduction and heat dissipation of the heat generated inside and transfer it to the outside, without affecting the sealing performance inside the shell 1, and at the same time improving the heat dissipation effect of its equipment components. The driving part 14 includes a movable scroll, a fixed scroll, a bracket, a cross slip ring, a crankshaft, and a driving source stator and rotor. This is a prior art, and the working The principle is not elaborated here. The rotating shaft 13 is connected to the output end of the driving member 14 to drive the rotating shaft 13 to rotate. When the rotating shaft 13 rotates inside the shell 1 to compress the refrigerant, it also drives the transmission components to make the eccentric wheel 24 rotate synchronously, so that the sound-absorbing liquid at the bottom of the cavity 3 can be extracted through the connected components and then sprayed upward obliquely, so that the internal sound-absorbing liquid flows to avoid internal precipitation. At the same time, the liquid at the top can be exchanged with the liquid at the bottom to improve the heat absorption effect inside the shell 1, and the flow of the sound liquid can absorb and disperse the energy of the sound wave, reduce the propagation and reflection of the sound wave, thereby further reducing the noise, and the liquid in The flow in the cavity 3 will produce a certain damping effect, which helps to reduce the transmission of vibration inside the compressor to the outside and further reduce the noise level. When the eccentric wheel 24 rotates ninety degrees, it can drive the compression element to compress the gas, and then transport it to the air bag b58, causing one side of it to expand, thereby squeezing and limiting the screws installed and fixed at the mounting hole 110, increasing the friction force, and effectively preventing the screws in the fixed state from loosening and displacing due to vibration generated by the operation of the equipment, thereby improving the stability of the structure. The compressed refrigerant is discharged through the air outlet 12, and the refrigerant inlet 15 is convenient for connecting to the refrigeration output pipe to enter the interior of the shell 1.

[0035] In a preferred embodiment, referring to Figure 5 and Figure 7A sound absorbing board 31 is fixedly installed on the inner wall of the cavity 3, and the end of the fixed block 28 is fixedly connected to the sound absorbing board 31. A conductive member 4 is arranged in the cavity 3, and the conductive member 4 includes a guide block 41 fixed on the surface of the sound absorbing board 31. Both ends of the guide block 41 are provided with inclined surfaces 42, and a guide hole 43 is opened inside the guide block 41. A heat sink 44 is embedded and installed on the inner wall of the guide block 41. The end of the heat sink 44 passes through the shell 1 and extends to the outside. An injection pipe 7 is fixedly connected to the outer wall of the shell 1. The injection pipe 7 is connected to the cavity 3, and a sealing cap is arranged on the injection pipe 7.

[0036] The shell 1 is made of aluminum alloy, which has a good thermal conductivity, so that the heat generated by the operation of the internal parts of the shell 1 is transferred to the cavity 3. The cavity 3 is filled with sound-absorbing liquid, which is injected into the cavity 3 through the injection tube 7. The sound-absorbing liquid uses mineral oil or a special synthetic sound-absorbing liquid. After filling the cavity 3, the inner wall of the shell 1 is covered with a protective layer, and the conducted heat can be transferred and absorbed by the sound-absorbing liquid. Since the heat sink 44 runs through the cavity 3, the heat in the sound-absorbing liquid can be transferred to the outside of the shell 1 through the heat sink 44 to effectively conduct and dissipate heat. On the other hand, a sound-absorbing board 31 is arranged on the inner wall of the cavity 3, wherein a plurality of holes are arranged on the surface of the sound-absorbing board 31 to avoid obstruction of heat transfer on the inner wall of the shell 1. The sound-absorbing board 31 can be used to initially absorb and reduce the noise generated by the internal operation of the shell 1. At the same time, the sound-absorbing liquid filled in the cavity 3 can form an external protective layer to reduce the propagation and reflection of sound waves.

[0037] In a preferred embodiment, referring to Figure 5 , Figure 6 and Figure 7 , a side surface of the eccentric wheel 24 is fixedly connected with a connecting shaft 23, one end of the connecting shaft 23 penetrates the housing 1 and extends to the inside and is fixedly connected with a matching gear 22, the surface of the matching gear 22 is meshed with a helical gear 21, and the axis of the helical gear 21 is fixedly connected to the surface of the rotating shaft 13, a side surface of the eccentric wheel 24 is fitted with an arc block 25, a side surface of the arc block 25 is fixedly connected with a slide bar 26, an end of the slide bar 26 is fixedly connected with a piston 27, the piston 27 is slidably connected in the connecting cylinder 272, one side surface of the piston 27 and the inner wall of the connecting cylinder 272 are fixedly connected with an extrusion spring 271, the extrusion spring 271 is sleeved on the surface of the slide bar 26, the two side surfaces of the connecting cylinder 272 are fixedly connected with fixed blocks 28, a side surface of the connecting cylinder 272 is provided with a washing liquid tube 29, one end of the connecting cylinder 272 is provided with an infusion tube 291, and a one-way valve is provided at the connection between the infusion tube 291 and the washing liquid tube 29 and the connecting cylinder 272.

[0038] When the rotating shaft 13 rotates, the connecting shaft 23 is driven to rotate through the helical gear 21 and the matching gear 22, and then the eccentric wheel 24 is driven to rotate. The eccentric wheel 24 reciprocates to squeeze the arc block 25, so that the piston 27 slides reciprocatingly inside the connecting cylinder 272, and then the sound-absorbing liquid at the bottom of the cavity 3 is drawn into the interior of the connecting cylinder 272 through the washing tube 29, and then sprayed out through the infusion tube 291. Since the infusion tube 291 is set at an oblique angle and points to one end of the guide block 41, the sprayed sound-absorbing liquid is inside the cavity 3, so that the sound-absorbing liquid inside accelerates the flow, and the sound-absorbing liquid Through the guide hole 43, the vortex is enhanced in a narrow space, further accelerating the flow of the fluid. On the one hand, the sound-absorbing liquid at the top of the cavity 3 is exchanged with the sound-absorbing liquid at the bottom, thereby improving the uniformity of heat absorption. On the other hand, the flow of the liquid in the cavity 3 will produce a certain damping effect, which helps to reduce the transmission of vibration inside the compressor to the outside and further reduce the noise level. Secondly, the sound-absorbing liquid passes through the surface of the heat sink 44, and the heat in the sound-absorbing liquid can be re-conducted through the heat sink 44 to accelerate the dissipation of heat, which does not affect the effect of sound absorption and noise reduction.

[0039] In a preferred embodiment, referring to Figure 3 , Figure 6 and Figure 8 A movable plate 51 is attached to the surface of the eccentric wheel 24, a movable rod 52 is fixedly connected to the bottom of the movable plate 51, an extrusion plate 53 is fixedly connected to the end of the movable rod 52, a compression piece is arranged at the bottom of the extrusion plate 53, and the two side surfaces of the extrusion plate 53 are slidably connected to the sound absorbing plate 31, the compression piece comprises an air bag a54 arranged on the inner wall of the cavity 3, a return spring 55 is installed inside the air bag a54, a flat plate is fixed to the end of the return spring 55, the flat plate is attached to the inner wall of the air bag a54, an air inlet 56 is fixed at one end of the air bag a54, a valve is arranged on the air inlet 56, one end of the air inlet 56 passes through the shell 1 and extends to the outside, the end of the air bag a54 is connected to the air guide pipe 57, one end of the air guide pipe 57 is connected to the air bag b58, the air bag b58 is embedded and installed in the mounting hole 110, a chamber 6 is opened inside the base 11, and the air guide pipe 57 is arranged in the chamber 6.

[0040] Among them, when the eccentric wheel 24 rotates 90° clockwise, it squeezes the movable plate 51, so that the squeezing plate 53 compresses the airbag a54, so that the air inside the airbag a54 is transported to the airbag b58 through the air duct 57, and one side of the airbag b58 expands, squeezing the bolts installed at the mounting hole 110, increasing the friction of the bolts, and preventing the bolts from loosening due to vibration when the compressor is working for a long time.

[0041] It should be understood that the airbag b58 is made of wear-resistant rubber material with a certain thickness, and the structure of the airbag b58 is intermittent expansion. With the elastic rebound of the return spring 55 and the upward movement of the extrusion plate 53, the deformation of the airbag a54 is restored, which does not affect the normal operation of the structure. The elastic force of the return spring 55 is greater than the volume weight of the sound-absorbing liquid in the cavity 3, and has a certain supporting force in the initial state.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
