TECHNICAL FIELD
[0001] The utility model relates to condensing cycle equipment technical field, especially relate to a kind of cascade condensing cycle device. BACKGROUND
[0002] Condensing cycle device realizes heat transfer and temperature control by the circulation of refrigerant between compressor, condenser, expansion valve and evaporator. During the circulation process, the compressor compresses the refrigerant into high-temperature and high-pressure gas, which enters the condenser to release heat and becomes liquid, then passes through the expansion valve to reduce pressure and enters the evaporator to absorb heat and evaporate, completing the entire refrigeration process. This structure is widely used in air conditioning, refrigeration and heat pump systems, and can efficiently exchange heat to achieve the purpose of cooling or heating.
[0003] In the condensing cycle device, cascade refrigeration refers to a refrigeration device composed of two or more single-stage (or double-stage) compression refrigeration cycle systems using two or more refrigerants. It is commonly used in low-temperature facilities such as ultra-low-temperature cold storage, rapid freezing process facilities, biological and chemical industries requiring ultra-low-temperature processes, and low-temperature boxes. The traditional cascade refrigeration structure mainly includes a high-temperature part and a low-temperature part. The high-temperature part uses a medium-temperature refrigerant, and the low-temperature part uses a low-temperature refrigerant. The two parts are connected by a condenser-evaporator to form a whole. However, in the cascade refrigeration structure, the condenser-evaporator, as a device capable of low-temperature condensation and high-temperature evaporation of air, needs to have good heat dissipation and refrigeration effect. However, due to the presence of static electricity during use, it is easy to accumulate dust on the surface, reducing the heat transfer coefficient of the condenser-evaporator and weakening the refrigeration or heating effect. At the same time, the accumulation of dust and dirt can accelerate the corrosion and aging of the equipment, shortening the service life of the equipment.
[0004] Therefore, the utility model provides a novel cascade condensing cycle device to solve the problems existing in the prior art. UTILITY MODEL CONTENTS

[0041] The cascade condensation cycle device is used for improving refrigeration efficiency, and is usually used for low-temperature refrigeration and air conditioning systems. It works by multiple condensation and evaporation levels, so that the refrigerant works in different temperature ranges, thereby realizing more efficient heat exchange. The system comprises multiple compressors, condensers, expansion valves and evaporators, and the refrigerant of each level is compressed, condensed, expanded and evaporated, so that the temperature is gradually reduced. Through the cascade design, the system can cover a wide temperature range, and is suitable for low-temperature storage, chemical cooling and the like, and has the advantages of high efficiency, energy saving and adaptation to various temperature control requirements.
[0042] As shown in the accompanying drawings of the specification, Figures 1-7 The utility model provides a technical scheme:
[0043] A cascade condensation cycle device, comprising: a condenser body 1, a fan 2 arranged beside the condenser body 1 and a guide assembly 3 arranged on the other side of the condenser body 1.
[0044] It should be noted that the condenser body 1 is a device that is relatively mature in application of the prior art, and the specific model can be selected according to actual needs. Meanwhile, the condenser body 1 can be powered by a built-in power supply or a commercial power supply, and the specific power supply mode is selected as appropriate, which will not be described here. In use, the fan 2 and the guide assembly 3 are used to clean the surface of the condenser body 1, so as to prevent dust from adhering to the surface of the condensing pipe 11 of the condenser body 1, thereby ensuring the heat dissipation and condensation effect of the condenser body 1 in use.
[0045] In a preferred embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the guide assembly 3 comprises a guide shell 302 arranged beside the condenser body 1, the air outlet end of the guide shell 302 is communicated with a pipeline 303, the air outlet end of the pipeline 303 is communicated with a cleaning pipe 304, a booster valve 305 is arranged at the connection between the pipeline 303 and the cleaning pipe 304; the guide assembly 3 further comprises a filter plate 301 arranged inside the guide shell 302, the area of the filter plate 301 is consistent with the condenser body 1; the guide shell 302 is arranged in a rectangular hollow shape, which facilitates fixing the filter plate 301 to the side close to the condenser body 1 through the guide shell 302; the cleaning pipe 304 is fixedly connected above the condenser body 1, and the air outlet at the lower part of the cleaning pipe 304 is arranged in an inclined manner.
[0046] It should be noted that in this embodiment, when it is necessary to clean the dust on the surface of the condensing pipe 11 in the condenser body 1, the fan 2 is first turned on, the fan 2 blows gas to the surface of the condensing pipe 11 of the condenser body 1, which can blow the dust on the surface of the condensing pipe 11 into the filter plate 301 along with the airflow, and the filter plate 301 can adsorb the dust in the gas, while the gas passing through the filter plate 301 enters the cleaning pipe 304 through the guide shell 302 and the pipeline 303. Since the pipeline 303 connected to the cleaning pipe 304 is narrow and the booster valve 305 is arranged at the connection between the pipeline 303 and the connecting pipe, the gas can be subjected to pressure boosting treatment through the booster valve 305, so that when the gas continuously enters the pipeline 303, the gas pressure will increase, and then the gas enters the cleaning pipe 304 and is sprayed downwardly and obliquely from the cleaning pipe 304, which can blow and clean the other side of the condensing pipe 11 in the condenser body 1, and the blown dust can be guided to the surface of the filter plate 301 again by the wind of the fan 2, which is cycled to achieve the effect of fully cleaning the condensing pipe 11 in the condenser body 1; the filter plate 301 can be detachably installed on the guide shell 302, and the filter plate 301 can be replaced when the surface of the filter plate 301 has too much dust.
[0047] Meanwhile, the booster valve 305 is arranged at the connection end of the pipeline 303 and the cleaning pipe 304, and the gas will be subjected to a certain pressure when passing through the booster valve 305. The flow channel design in the booster valve 305 slows down the gas flow and accumulates a certain pressure, until the pressure reaches the set value. When the gas flows through the booster valve 305, the speed of the gas will rapidly increase due to the narrowing of the flow channel, thereby realizing high-pressure and high-speed injection, so that the gas can be sprayed from top to bottom to the surface of the condensing pipe 11 to clean the dust on the other side of the condensing pipe 11, and the gas flow can not be disturbed by the fan 2.
[0048] In use, the pressure booster valve 305 can perform a pressure boosting operation every certain period of time, through the internal timer or program controller, automatically adjusting the opening degree or operating state of the pressure booster valve 305 within the set time interval, and every time the set time point is reached, the control system sends a signal to trigger the pressure booster valve 305 to perform a pressure boosting operation, and the pressure feedback control is monitored by the pressure sensor to monitor the pressure change in the pipeline 303, and when the pressure drops below the set threshold, the pressure booster valve 305 automatically activates the pressure boosting operation, and the valve driver is combined with the pneumatic system to periodically adjust the pressure through the pneumatic actuator and the pneumatic system for controlling the valve, so that the condenser body 1 can be periodically cleaned by the jet, and during daily use, the straight blowing airflow of the fan 2 will not be affected by the high-pressure airflow.
[0049] In a preferred embodiment, as shown in Figure 5 and Figure 7 The pipeline 303 is provided with a guide pipe 306 on the side close to the cleaning pipe 304, and the guide pipe 306 is provided with two; both of the guide pipes 306 are inverted, and both of the guide pipes 306 are flat mouth pipes; the angle of the guide pipe 306 is away from the side of the cleaning pipe 304, and the horizontal angle of the guide pipe 306 is inclined downward.
[0050] It should be noted that through the above-mentioned guide pipe 306, when the gas flows in the pipeline 303 to the cleaning pipe 304, the guide pipe 306 on the surface of the pipeline 303 can spray part of the gas in the pipeline 303, and since the guide pipe 306 is flat, the gas pressure of the guide pipe 306 is greater, and the flat-shaped nozzle can form a barrier to prevent dust falling from above from being guided to the surface of the filter plate 301, and prevent the dust from falling on the surface of the condenser body 1 again.
[0051] In a preferred embodiment, as shown in Figure 6 The lower side of the cleaning pipe 304 is provided with a plurality of flow guide holes in communication with the pipeline 303, and the airflow is guided to the surface of the condensing pipe 11 through the flow guide holes to clean the surface of the condensing pipe 11.
[0052] The working principle of the cascade condensation circulating device includes: when the condensation circulating device is running, dust will be generated on the surface of the condenser body 1, at this time the fan 2 is opened, the fan 2 blows the gas to the surface of the condensing pipe 11 of the condenser body 1, the dust on the surface of the condensing pipe 11 can be blown into the filter plate 301 along the airflow, the filter plate 301 can adsorb the dust in the gas, and the gas passing through the filter plate 301 enters the cleaning pipe 304 through the guide shell 302 and the pipeline 303, because the pipeline 303 of the cleaning pipe 304 is narrow and a booster valve 305 is arranged at the connection between the pipeline 303 and the connecting pipe, the booster valve 305 can perform pressure boosting treatment on the gas, so when the gas continuously enters the pipeline 303, the gas pressure will increase, then the gas enters the cleaning pipe 304 and is sprayed obliquely downward from the cleaning pipe 304, the other side of the condensing pipe 11 in the condenser body 1 can be blown and cleaned, and the blown dust can be directed to the surface of the filter plate 301 again by the wind of the fan 2, so that the effect of comprehensive cleaning is achieved; at the same time, the guide pipe 306 arranged on the surface of the pipeline 303 can spray part of the gas in the pipeline 303, because the guide pipe 306 is arranged in a flat mouth, the gas pressure of the guide pipe 306 is larger, and the flat mouth-shaped nozzle can form a barrier to guide the falling dust on the surface of the filter plate 301, preventing the dust from falling on the surface of the condenser body 1 again.
[0053] It should be noted that the condenser body 1, the condensing pipe 11, the fan 2, the booster valve 305 and the like in the above description are all relatively mature devices in the prior art, and the specific model can be selected according to actual needs, and the power supply of the condenser body 1, the fan 2 and the booster valve 305 can be built-in power supply or mains power supply, and the specific power supply mode is selected as needed, which will not be repeated here.
[0054] The above is only a preferred embodiment of the utility model, and is not used to limit the protection scope of the utility model.
