Description

Technical Field

[0001] The invention relates to the technical field of granary equipment, in particular to a buoy-type grain surface air-conditioning humidifier. Background Art

[0002] The grain surface refers to the surface area of ​​bulk grain stored in a granary, a sensitive zone to changes in temperature and humidity. Low-temperature grain storage has become a trend, and grain air conditioning systems play a key role in improving grain quality and preventing pests. However, existing grain air conditioners lack humidification. While cooling the granary, these air conditioners also remove moisture from the grain, reducing its moisture content and increasing storage losses. As the moisture evaporates from the grain, the hot and humid air rises. Upon encountering the cold metal ceiling, it rapidly cools below the dew point, condensing into water droplets. Experimental results show that when the temperature difference between the inside and outside of the silo is ≥3°C, the metal ceiling can produce dew condensation of 0.5-1.2L / m² / day.

[0003] Existing grain air conditioning units lack space for installing a complete humidifier due to their compact structure and weight limitations. Furthermore, adding a humidification function to ordinary grain air conditioners requires connecting the air conditioner to a water pipe and installing a complete humidification system inside the air conditioning unit. However, in reality, grain warehouses do not have the conditions to connect each air conditioner to a water pipe, and water leakage accidents are prone to occur, which are fatal to the grain stored in the granary. At the same time, because most grain air conditioners are hoisted on the outer wall of the granary, installing a complete humidification system will increase the size and weight of the air conditioning unit itself, which will not only affect the overall appearance but also create a safety hazard to the wall.

[0004] Upon investigation, a Chinese invention patent discloses a grain air-conditioning device that recycles evaporated condensed water and has its own ultrasonic atomization plate (publication number: CN114857704A), which includes a heat exchanger, a blower and a water tank. The device also includes a water tank recess, an overflow port, a liquid level alarm switch and an ultrasonic atomization plate; a water tank recess is provided in the middle of the water tank for storing evaporated condensed water and increasing space; an ultrasonic atomization plate is detachably provided on the bottom surface of the inner part of the water tank recess for atomizing the liquid using ultrasonic waves to achieve humidification; the liquid level alarm switch is movably provided on the left side surface of the inner part of the water tank recess for turning on and off the humidification function.

[0005] Although the above patent realizes the condensation water collection and humidification functions by redesigning the internal structure of the water tank of the grain air conditioner and improving the electrical control system, and has safety, the water evaporated from the grain pile will condense into water droplets when it encounters the iron ceiling of the granary. The water droplets will flow into the grain along the silo wall and concentrate at the edge of the grain pile, causing the grain at the edge to mold. If the condensation water is collected and processed, it can not only solve the problem of grain mold at the edge of the grain pile, but also replenish water for the humidifier of the granary. However, this device does not have the ability to process the condensation water on the granary ceiling, and the treatment of the condensation water on the ceiling is imminent.

[0006] Therefore, the present invention provides a buoy-type grain surface air-conditioning humidifier to solve the above problems. Summary of the Invention

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The present invention provides a buoy type grain surface air conditioning humidifier, such as Figures 1-10As shown, the technical solution includes a granary 1, a metal roof 9 and a wet film humidifier 20. The metal roof 9 is fixedly connected to the granary 1. A water supply pipe 4 is provided on the outer wall of the granary 1.

A water inlet pipe 18 is sealed between the top of the water tank 8 and the water supply pipe 4. It should be noted that a 5μm filter and UV sterilizer are provided at the mouth of the water inlet pipe 18. 5μm precision filtration is a separation technology that efficiently intercepts micron-sized particles through filter materials with specific pore sizes. UV sterilization technology uses ultraviolet rays to destroy the DNA / RNA structure of microorganisms, causing them to lose their reproductive ability, thereby achieving non-chemical contact sterilization. 5μm filtration and UV sterilizers are both existing technologies and will not be elaborated on here. A water outlet pipe 19 is sealed between the side wall of the water tank 8 and the wet film humidifier 20. A quantity control mechanism is provided in the water tank 8, which includes a float 16, a metal ball 31, a connecting plate 28 and two metal blocks 29. A connecting rod 30 is fixedly connected between the metal ball 31 and the float 16, and the connecting rod 30 is rotatably connected to the connecting plate 28. The condensed water at the metal ceiling 9 is collected into the water tank 8 through the guide groove 36 and the water supply pipe 4. When the liquid level in the water tank 8 reaches the height of the float 16, the float 16 drives the metal ball 31 to offset the metal block 29, which can drive the circulating water pump 17 and the first motor 12 to start, humidifying the grain in the granary 1, which not only solves the problem of grain moldy at the edge of the grain pile due to condensed water, but also replenishes water for the wet film humidifier 20 and controls the timing of grain humidification. Symmetrical mounting holes are provided on the side walls of the granary 1, and a mounting box 2 is fixedly connected to the mounting holes. A dustproof net 5 is fixedly installed on the side walls of the mounting box 2. A cleaning mechanism is provided between the dustproof net 5 and the mounting box 2. The cleaning mechanism includes a mounting plate 7, a brush plate 37, two striking blocks 26, multiple round rods 42 and a spring 43. The spring 43 is sleeved on the round rod 42, and the round rod 42 is fixedly connected to the mounting plate 7. The dust on the dustproof net 5 is cleaned by the cooperation of the striking block 26 and the brush plate 37. The resetting ability of the spring 43 is used to drive the striking block 26 to knock on the dustproof net 5, and the brush plate 37 rotates to clean the dust on the dustproof net 5 to prevent the dustproof net 5 from being blocked, so as not to affect the air passing through the wet film humidifier 20 to humidify the grain in the granary 1.

The two ends of the connecting plate 28 are fixedly connected with sliders 27, and the screw rod 25 passes through the slider 27 and is threadedly connected to the slider 27. The top of the water tank 8 is rotatably connected with two third pulleys 32, and the third pulley 32 is coaxially fixed with the screw rod 25. A third transmission belt 33 is connected between the two third pulleys 32 for transmission. A circulating water pump 17 is provided in the water tank 8, and the circulating water pump 17 is sealed with the water outlet pipe 19. A deflector 24 is provided below the water inlet pipe 18, and the deflector 24 is fixedly connected to the water tank 8. The deflector 24 is provided to prevent water entering the water tank 8 from hitting the float 16, causing the metal ball 31 to accidentally touch the metal block 29. A second motor 34 is fixedly connected to the top of the water tank 8, and the output end of the second motor 34 is coaxially fixed with the screw rod 25. When in use, the second motor 34 is started, and the two screw rods 25 are driven to rotate synchronously under the action of the third pulley 32 and the third transmission belt 33. The rotating screw rod 25 drives the slider 27 and the connecting plate 28 to move, and then drives the float 16 to rise and fall, and adjusts the height of the float 16. The evaporation amount of water in the grain is estimated according to the area of ​​the granary 1 and the amount of grain stacked, and the height of the float 16 in the water tank 8 is adjusted. After the water in the grain evaporates to a certain amount, the water in the water tank 8 can use the buoyancy to push the float 16 to move, so that the metal ball 31 contacts the metal block 29, and the grain in the granary 1 is humidified in time to avoid excessive evaporation of water in the grain, failure to replenish water in time, or too little evaporation of water, or too much replenishment of water.

[0025] Reference Figure 3 and Figure 8As shown, a protective net 10 is fixedly installed in the mounting hole, and the protective net 10 is provided to protect the wet film humidifier 20 and prevent food from entering the mounting hole. The wet film humidifier 20 is installed in the mounting hole, and a mounting frame 11 is fixedly connected to the mounting box 2. One side of the mounting frame 11 is rotatably connected to the mounting shaft 35, and the mounting shaft 35 passes through the dustproof net 5 and is fixedly connected to the mounting plate 7. A first U-shaped plate 38 is fixedly connected to the brush plate 37, and a second U-shaped plate 40 is fixedly connected to the striking block 26. The first U-shaped plate 38 and the second U-shaped plate 40 are both slidably connected to the mounting plate 7, and a plurality of round rods 42 slide through the first U-shaped plate 38 and the second U-shaped plate 40 respectively. One end of a plurality of springs 43 is fixed to the mounting plate 7 The first U-shaped plate 38 and the second U-shaped plate 40 are fixedly connected, and the other ends of the multiple springs 43 are fixedly connected to the first U-shaped plate 38 and the second U-shaped plate 40 respectively. A limiting groove 39 is provided on the side wall of the first U-shaped plate 38, and a limiting block 41 is fixedly connected to the side wall of the second U-shaped plate 40, and the limiting block 41 is slidably connected in the limiting groove 39; the cross section of the striking block 26 is arranged in an isosceles trapezoid. When the inclined surface of the striking block 26 is squeezed, the striking block 26 is pushed to move toward the mounting plate 7. When any striking block 26 moves toward the mounting plate 7, under the action of the limiting block 41 and the limiting groove 39, the brush plate 37 can be driven to move toward the mounting plate 7. A plurality of partitions 6 are fixedly connected to the side wall of the dustproof net 5, and the striking block 26 is against the partition 6; During use, the mounting shaft 35 is rotated, and the mounting shaft 35 drives the mounting plate 7 to rotate. The brush plate 37 on the mounting plate 7 cleans the dust on the dustproof net 5. When the inclined surface of the striking block 26 contacts the partition 6, the striking block 26 and the brush plate 37 respectively drive the second U-shaped plate 40 and the first U-shaped plate 38 to squeeze the spring 43 and move toward the mounting plate 7. When the striking block 26 no longer contacts the partition 6, the spring 43 resets and pushes the striking block 26 to knock on the dustproof net 5, thereby removing dust from the dustproof net 5 and preventing the dustproof net 5 from being blocked, so as not to affect the air passing through the wet film humidifier 20 to humidify the grain in the granary 1.

[0026] Reference Figure 4 and Figure 6As shown, a rotating rod 13 is provided above the installation box 2, and a second pulley 22 is coaxially fixed on the rotating rod 13 and the installation shaft 35, and a second transmission belt 23 is connected between the two second pulleys 22. A fan blade 21 is provided on one side of the wet film humidifier 20, and the fan blade 21 is rotatably connected to the installation frame 11, and a first pulley 14 is coaxially fixed on the fan blade 21 and the rotating rod 13, and a first transmission belt 15 is connected between the two first pulleys 14. A connecting shell 3 is provided above the metal ceiling 9, and an end of the connecting shell 3 is fixedly connected to the installation box 2, and a first motor 12 is fixedly connected in the connecting shell 3. The rotating rod 13 is rotatably connected in the connecting shell 3, and the output end of the first motor 12 is coaxially fixed with the connecting shell 3. The two metal blocks 29 are electrically connected to the circulating water pump 17 and the first motor 12. When the metal ball 31 is against the two metal blocks 29, the circuit of the circulating water pump 17 and the first motor 12 is closed. During use, water droplets on the metal ceiling 9 are collected and sent into the water tank 8, the liquid level in the water tank 8 rises, and the buoyancy of the water pushes the float 16 to rise. Under the action of the connecting rod 30, the float 16 drives the metal ball 31 on the connecting rod 30 to move. When the metal ball 31 is against the two metal blocks 29, the circuit of the circulating water pump 17 and the first motor 12 is closed, and the circulating water pump 17 transports the water in the water tank 8 to the wet film humidifier 20 through the outlet pipe 19. The first motor 12 drives the rotating rod 13 to rotate, and the rotating rod 13 drives the fan blades 21 to rotate through the first pulley 14 and the first transmission belt 15, and the air passes through the wet film humidifier 20 into and out of the granary 1. The rotating rod 13 drives the mounting shaft 35 and the mounting plate 7 to rotate through the second pulley 22 and the second transmission belt 23, thereby driving the cleaning mechanism to operate and clean the dust on the dustproof net 5.

[0027] It should be noted that the first motor 12 and the second motor 34 are both connected to an external power supply through a wire. The external power supply includes a battery for providing power to the first motor 12 and the second motor 34 and a control switch for controlling the start and stop thereof. The external power supply is a prior art. The second motor 34 is a servo motor, and its output end can achieve forward and reverse rotation by changing the direction of the current. The specific model specifications of the first motor 12 and the second motor 34 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. In summary: when working, the second motor 34 is started, and the two screw rods 25 are driven to rotate synchronously under the action of the third pulley 32 and the third transmission belt 33. The rotating screw rod 25 drives the slider 27 and the connecting plate 28 to move, and then drives the float 16 to rise and fall, and adjusts the height of the float 16. The water vapor evaporated from the grain in the granary 1 encounters the metal roof 9 and condenses into water droplets. The water droplets on the metal roof 9 flow into the water delivery pipe 4 through the guide groove 36, and then flow into the water tank 8 through the water inlet pipe 18. When the water in the water tank 8 rises to a certain height, the buoyancy of the water will push the float 16 to rise, and under the action of the connecting rod 30, the water vapor evaporated from the grain in the granary 1 encounters the metal roof 9 and condenses into water droplets. The water droplets on the metal roof 9 flow into the water delivery pipe 4 through the guide groove 36, and then flow into the water tank 8 through the water inlet pipe 18. When the water in the water tank 8 rises to a certain height, the buoyancy of the water will push the float 16 to rise. Under the action of the floating ball 16, the metal ball 31 on the connecting rod 30 moves. When the metal ball 31 contacts the two metal blocks 29, the circuit of the circulating water pump 17 and the first motor 12 is closed. The circulating water pump 17 transports the water in the water tank 8 to the wet film humidifier 20 through the outlet pipe 19. The first motor 12 drives the rotating rod 13 to rotate. The rotating rod 13 drives the fan blades 21 to rotate through the first pulley 14 and the first transmission belt 15, and the air passes through the wet film humidifier 20 and enters and exits the granary 1. The rotating rod 13 drives the mounting shaft 35 and the mounting plate 7 to rotate through the second pulley 22 and the second transmission belt 23. When the mounting plate 7 rotates, the brush plate 37 on the mounting plate 7 cleans the dust on the dustproof net 5. When the inclined surface of the striking block 26 contacts the partition 6, the striking block 26 drives the brush plate 37 to squeeze the spring 43 and move toward the mounting plate 7. When the striking block 26 no longer contacts the partition 6, the spring 43 returns to its original position and pushes the striking block 26 to knock on the dustproof net 5, thereby removing dust from the dustproof net 5.
