Description

Technical Field

[0001] The invention relates to the technical field of grain coolers, in particular to a condensed water recovery and cooling device for a grain cooler. Background Art

[0002] A grain cooler is a mobile refrigeration, humidity control and ventilation equipment used in the fields of agronomy and food science and technology for low-temperature storage of grains. When in use, the inhaled air is mainly heat-exchanged with a low-temperature refrigerant through an evaporator to lower its temperature and enter the grain pile through air supply ducts and air distributors. When the cooler is running, the evaporator will lower the temperature of the surrounding air and condense it into condensed water on the surface of the evaporator. In order to save energy and reduce consumption and improve refrigeration performance, a condensed water recovery and cooling device is usually provided on the cooler to recover and utilize the condensed water.

[0003] When a traditional grain cooler is in operation, a large amount of low-temperature condensed water will be generated on the surface of the evaporator inside it. The condensed water usually drips directly into the water storage pan at the bottom of the evaporator and is discharged to the outside through a pipe, which easily causes a waste of resources. In addition, since the condenser generates a lot of heat when working, the workload of the compressor is increased, thereby affecting the heat exchange efficiency of the condenser. At this time, the condensed water is not effectively recycled, affecting the overall refrigeration performance of the cooler, and the practicality is poor. When the condensed water is recovered, the water droplets condensed on the surface of the evaporator will drop into the water storage pan under the action of gravity. However, the cooler needs to continuously inhale the outside air when in use, and the dust particles will diffuse inside the cooler with the air flow and deposit on the surface of the evaporator. At this time, the dust will drop into the water storage pan with the condensed water and settle. After long-term use, it will cause the water outlet pipe to be blocked. Moreover, when the water storage pan is removed to clean the dust deposited inside, the internal space of the cooler is small, which makes it inconvenient to operate and has poor flexibility. When the grain cooler is working, outside air enters the equipment under the action of the fan, and the dust in the air will be blocked by the filter. If the dust accumulates too much, it will clog the filter, reducing the air volume passing through the condenser, causing the refrigerant to fail to liquefy normally in the condenser, affecting the refrigeration effect of the cooler. The filter is often removed and cleaned by dismantling the bolts, which requires repeated disassembly and tightening of the bolts. The operation process is cumbersome and the cleaning efficiency is low. Summary of the invention

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figure 2 , Figure 4-Figure 11As shown, a condensate recovery and cooling device for a grain cooler according to the present invention comprises a cooler body 1, a recovery structure 2 installed inside the cooler body 1, a monitoring structure 3 arranged on the recovery structure 2, a filtering structure 4 installed on the recovery structure 2, a driving structure 7 arranged at the bottom of the cooler body 1, and a cleaning structure 8 installed on the outer wall of the cooler body 1; the recovery structure 2 comprises a water storage pan 201 and a docking joint 202 fixedly connected to the bottom of the water storage pan 201, the top of the cooler body 1 is fixedly connected to the water storage pan 201, the bottom of the docking joint 202 is fixedly connected to a first connecting pipe 203, the bottom of the cooler body 1 is fixedly connected to a water storage tank 205, and the bottom of the cooler body 1 A water pump 206 is fixedly connected, a bend pipe 207 is fixedly connected to the water inlet of the water pump 206, a second connecting pipe 208 is fixedly connected to the water outlet of the water pump 206, a monitoring structure 3 is provided inside the water storage tank 205, an evaporator 5 is fixedly connected to the inside of the water storage pan 201, the top of the evaporator 5 is fixedly connected to the inner wall of the cooling machine body 1, an inclined surface is provided inside the water storage pan 201, a condenser 6 is fixedly connected to the inside of the water storage tank 205, the second connecting pipe 208 is fixedly connected to the side wall of the cooling machine body 1, an atomizing nozzle 209 is fixedly connected to the end of the second connecting pipe 208, and a plurality of drip heads 204 are fixedly connected to the end of the first connecting pipe 203 close to the condenser 6;During the use of the cooling machine body 1, the blower 10 inside the cooling machine body 1 transports the outside air to the inside of the evaporator 5. At this time, the compressor 9 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and sends it to the inside of the condenser 6 through a pipeline. In the condenser 6, the high-temperature and high-pressure gas dissipates heat to the outside and becomes a liquid at normal temperature and high pressure. Then, it is throttled and reduced in pressure by the expansion valve to become a low-temperature and low-pressure liquid refrigerant. Then, it is transported to the evaporator 5 again through a pipeline. At this time, the air and the low-temperature refrigerant perform heat exchange to reduce the temperature of the air. At the same time, the low-temperature refrigerant is once again converted into a low-temperature and low-pressure gas and is sucked into the compressor 9. This cycle repeats and the cold air after temperature and humidity control is transported to the inside of the ventilation pipe 801 through another blower 10, and is transported to the inside of the granary by the ventilation pipe 801, thereby achieving the effect of cooling the grains. However, during the operation of the cooling machine body 1, the evaporator 5 will reduce the temperature of the surrounding air and condense into water droplets on the surface of the evaporator 5 to form condensed water. At this time, the condensed water drops to the inside of the water storage pan 201 at the bottom of the evaporator 5. The inner bottom surface of the water storage pan 201 is an inclined surface, and the condensed water flows from the inclined surface to the docking joint 202 at the end of the water storage pan 201, and flows from the docking joint 202 into the inside of the first connecting pipe 203 at the bottom, and then drips from the drip head 204 at the end of the first connecting pipe 203 to the surface of the condenser 6 below, which not only has a cooling effect on the condenser 6, but also the excess condensed water slides from the surface of the condenser 6 to the inside of the water storage tank 205 at the bottom, and the cycle is repeated until enough condensed water is stored in the water storage tank 205. When the quality of the grain deteriorates or the flavor changes due to drying, the interior of the granary can be humidified. At this time, the power supply of the water pump 206 can be turned on. At this time, the water pump 206 absorbs the condensed water inside the water storage tank 205 through the bent pipe 207, and then transports it to the atomizing nozzle 209 at its end through the second connecting pipe 208. The atomizing nozzle 209 sprays the condensed water outward in the form of water mist. Since the atomizing nozzle 209 is arranged at the butt joint 802, the water mist can be blown into the granary with the cold wind, thereby achieving the effect of cooling and humidifying the grains in the granary, which is highly practical. ;

[0024] Specifically, Figure 4 , Figure 8 and Fig.11As shown, the monitoring structure 3 includes a bottom tube 301 and a driving rod 302 slidably connected to the bottom tube 301. The bottom tube 301 is fixedly connected to one end of the water storage tank 205 near the elbow 207. The bottom of the driving rod 302 is threadedly connected to a rubber plug 303. The rubber plug 303 is slidably connected to the inner wall of the bottom tube 301. The top of the driving rod 302 is fixedly connected to a connecting piece 306. The upper and lower surfaces of the connecting piece 306 are respectively fixedly connected to a floating ball 307 and a water quality detection probe 308. The bottom tube 301 is provided with a water outlet 309. A baffle 304 is fixedly connected to the center of the driving rod 302, and the side wall of the baffle 304 is slidably connected to the inner wall of the bottom tube 301, and a first spring 305 is fixedly connected between the upper surface of the baffle 304 and the inner wall of the bottom tube 301. A blower 10 is fixedly connected to the inside of the cooling machine body 1, and a compressor 9 is fixedly connected to the inside of the cooling machine body 1. Since condensed water is continuously generated on the surface of the evaporator 5 during the operation of the cooling machine body 1, when the liquid level of the condensed water reaches a certain height in the process of accumulating condensed water in the water storage tank 205, the floating ball Under the buoyancy of 307, the float 307 drives the connecting piece 306 and the driving rod 302 at the bottom to move upward, and the connecting piece 306 drives the water quality detection probe 308 to move upward. When the water pump 206 absorbs water, the liquid level will drop, and the float 307 will drive the water quality detection probe 308 to move downward, so that the water quality detection probe 308 can detect the water quality at different liquid levels, avoiding the deterioration or condensed water with more impurities from being transported to the interior of the granary, which is highly practical. At the same time, when the liquid level continues to rise, the float 307 continues to drive the driving rod 302 to move upward, and the driving rod 30 2 drives the rubber plug 303 at the bottom to move upward. When the rubber plug 303 moves to the top of the water outlet hole 309 on the bottom tube 301, the internal space of the water storage tank 205 is convenient for conduction to the outside. At this time, the condensed water is discharged to the outside through the bottom tube 301, which effectively avoids the problem of condensed water overflowing from the inside of the water storage tank 205. When the liquid level drops to a certain extent, it resists the baffle 304 downward under the reset action of the first spring 305. The baffle 304 drives the rubber plug 303 to slide downward until it slides to the bottom. At this time, the bottom tube 301 is sealed, which is convenient for the subsequent storage of condensed water and has strong flexibility.

The bottom of the limit rod 406 is threadedly connected with a nut 407, and the upper surface of the nut 407 abuts against the bottom surface of the water storage tray 201. The end of the water storage tray 201 close to the holder 401 is fixedly connected with a filter element 408. Two guide bars 409, a sedimentation hopper 410 is slidably connected between the two guide bars 409, and the sedimentation hopper 410 is engaged between the base 401 and the inner wall of the water storage tray 201, and the limit rod 406 is an elliptical structure; before the condensed water flows from the water storage tray 201 to the water storage tank 205, the condensed water will first pass through the filter element 408 at the end of the water storage tray 201, and the dust will be deposited in the sedimentation hopper 410 in front of the filter element 408. The sedimentation hopper 410 is engaged between the two guide bars 409, which is convenient for disassembly. When the filter element 408 needs to be cleaned or replaced , just turn the nut 407 at the bottom of the limit rod 406 and rotate the nut 407 to the bottom of the limit rod 406. At this time, the push plate 403 pushes up the two mounting blocks 405 under the resetting action of the second spring 404, and the two mounting blocks 405 slide upward along the base 401 and the guide rod 402 until the filter element 408 completely slides out of the water storage tray 201, which is convenient for disassembly, cleaning and replacement. When the disassembly and cleaning is completed, just reverse the nut 407. The operation is simple, and the filter element 408 can effectively filter out dust, bacteria, etc. in the condensed water to ensure the safety of grain storage.

If it is not cleaned in time, it will hinder the air circulation. At the same time, the dust may be blown into the grain pile with the air flow and contaminate the grain. When it is necessary to clean the filter 806 inside the ventilation pipe 801, just turn on the power of the motor 810, and the motor 810 drives the cam 811 on the output shaft to rotate.

At this time, the compressor 9 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and sends it to the inside of the condenser 6 through a pipeline. In the condenser 6, the high-temperature and high-pressure gas dissipates heat to the outside and becomes a liquid at normal temperature and high pressure. Then, it is throttled and reduced in pressure by the expansion valve to become a low-temperature and low-pressure liquid refrigerant. Then, it is transported to the evaporator 5 again through a pipeline. At this time, the air and the low-temperature refrigerant perform heat exchange to reduce the temperature of the air. At the same time, the low-temperature refrigerant is once again converted into a low-temperature and low-pressure gas and is sucked into the compressor 9. This cycle repeats and the cold air after temperature and humidity control is transported to the inside of the ventilation pipe 801 through another blower 10, and is transported to the inside of the granary by the ventilation pipe 801, thereby achieving the effect of cooling the grains. However, during the operation of the cooling machine body 1, the evaporator 5 will reduce the temperature of the surrounding air and condense into water droplets on the surface of the evaporator 5 to form condensed water. At this time, the condensed water drops to the inside of the water storage pan 201 at the bottom of the evaporator 5. The inner bottom surface of the water storage pan 201 is an inclined surface, and the condensed water flows from the inclined surface to the docking joint 202 at the end of the water storage pan 201, and flows from the docking joint 202 into the inside of the first connecting pipe 203 at the bottom, and then drips from the drip head 204 at the end of the first connecting pipe 203 to the surface of the condenser 6 below, which not only has a cooling effect on the condenser 6, but also the excess condensed water slides from the surface of the condenser 6 to the inside of the water storage tank 205 at the bottom, and the cycle is repeated until enough condensed water is stored in the water storage tank 205. When the quality of the grain deteriorates or the flavor changes due to drying, the interior of the granary can be humidified. At this time, the power supply of the water pump 206 can be turned on. At this time, the water pump 206 absorbs the condensed water inside the water storage tank 205 through the bent pipe 207, and then transports it to the atomizing nozzle 209 at its end through the second connecting pipe 208. The atomizing nozzle 209 sprays the condensed water outward in the form of water mist. Since the atomizing nozzle 209 is arranged at the docking pipe 802, the water mist can be blown into the granary with the cold wind, thereby achieving the effect of cooling and humidifying the grains in the granary, which is highly practical. Since condensed water is continuously generated on the surface of the evaporator 5 during the operation of the cooling machine body 1, and condensed water is accumulated inside the water storage tank 205, when the liquid level of the condensed water reaches a certain height, under the buoyancy of the float 307, the float 307 drives the connecting piece 306 and the driving rod 302 at the bottom to move upward, and the connecting piece 306 drives the water quality detection probe 308 to move upward, and when the water pump 206 absorbs water, the liquid level will drop, and the float 307 will drive the water quality detection probe 308 to move downward, so that the water quality detection probe 308 can detect the water quality at different liquid levels, so as to avoid the condensed water that is deteriorated or has more impurities being transported to the interior of the granary, which is practical. At the same time, when the liquid level During the continuous rising process, the float 307 continuously drives the driving rod 302 to move upward, and the driving rod 302 drives the rubber plug 303 at the bottom to move upward. When the rubber plug 303 moves to the top of the water outlet hole 309 on the bottom tube 301, the internal space of the water storage tank 205 is convenient for conduction to the outside. At this time, the condensed water is discharged to the outside through the bottom tube 301, which effectively avoids the problem of condensed water overflowing from the inside of the water storage tank 205. When the liquid level drops to a certain extent, it resists the baffle 304 downward under the reset action of the first spring 305, and the baffle 304 drives the rubber plug 303 to slide downward until it slides to the bottom. At this time, the bottom tube 301 is sealed, which is convenient for the subsequent storage of condensed water and has strong flexibility. Before the condensed water flows from the water storage tray 201 to the water storage tank 205, the condensed water will first pass through the filter element 408 at the end of the water storage tray 201, and at the same time, dust will be deposited in the sedimentation bucket 410 in front of the filter element 408. The sedimentation bucket 410 is engaged between the two guide bars 409 for easy disassembly. When it is necessary to clean or replace the filter element 408, it is only necessary to rotate the nut 407 at the bottom of the limit rod 406 and rotate the nut 407 to the bottom of the limit rod 406. At this time, the push plate 403 pushes up the two mounting blocks 405 under the reset action of the second spring 404, and the two mounting blocks 405 slide upward along the card seat 401 and the guide rod 402 until the filter element 408 completely slides out of the water storage tray 201, so as to facilitate disassembly, cleaning and replacement. When the disassembly and cleaning is completed, it is only necessary to reverse the nut 407, which is easy to operate, and the filter element 408 can effectively filter out dust, bacteria, etc. in the condensed water to ensure the safety of grain storage. During the long-term use of the cooling machine body 1, the air inlet and outlet installed on the cooling machine body 1 need to inhale or exhaust air for a long time, which may easily cause a large amount of dust to adhere to the internal filter 806. If it is not cleaned in time, the air circulation will be blocked. At the same time, the dust may be blown into the grain pile with the air flow and contaminate the grain. When it is necessary to clean the filter 806 inside the ventilation pipe 801, it is only necessary to turn on the power of the motor 810. The motor 810 drives the cam 811 on the output shaft to rotate. The cam 811 rotates one circle and will downwardly resist the rotating shaft on the connecting block 808. Wheel 809, and cam 811 continues to make circular motion, and a tension spring 805 is fixedly connected between the top surface of the mounting frame 804 and the inner wall of the ventilation pipe 801, and then the cam 811 drives the mounting frame 804 and the filter 806 to make reciprocating up and down motions, thereby achieving the effect of shaking the filter 806 up and down, so that the dust adhering to the surface of the filter 806 falls to the ground through the through groove 807, thereby realizing automatic cleaning of the dust on the filter 806, and the cleaning efficiency is high. In addition, since the mounting frame 804 slides up and down between the four positioning bars 803, it has strong flexibility.
