It includes a grain storage silo, a metal roof, and a wet film humidifier. The metal roof is fixedly connected to the grain storage silo. A water supply pipe is provided on the outer wall of the grain storage silo. A guide channel is provided between the metal roof and the water supply pipe.

Description

Technical Field

[0001] This invention relates to the field of grain storage equipment technology, specifically a buoy-type grain surface air conditioning humidifier. Background Technology

[0002] The grain surface refers to the surface area of ​​the bulk grain pile inside a grain silo. It is a sensitive zone to changes in temperature and humidity within the silo. Currently, low-temperature grain storage has become a trend, and grain air conditioning systems play a crucial role in improving grain quality and preventing pests. However, existing grain air conditioning systems do not have humidification functions. While cooling the grain silo, these systems also remove moisture from the grain, reducing its moisture content and increasing storage losses. After the moisture in the grain evaporates, the humid and hot air formed by the evaporation rises and rapidly cools below the dew point when it encounters the low-temperature metal roof, condensing into water droplets. Experiments show that when the temperature difference between inside and outside the silo is ≥3℃, the condensation on the metal roof can reach 0.5-1.2 L / m²·day.

[0003] Existing grain air conditioning units, due to their compact structure and weight limitations, lack the space to install a complete humidifier. Furthermore, adding humidification to ordinary grain air conditioners requires connecting the air conditioner to a separate water pipe and installing a complete humidification system within the air conditioning unit. However, in reality, grain depots do not have the conditions to connect water pipes to every air conditioner, and leaks are prone to occur, posing a fatal threat to grain storage. At the same time, since most grain air conditioners are suspended on the outer walls of the grain depot, adding a complete humidification system would increase the size and weight of the air conditioning unit itself, affecting the overall aesthetics and creating safety hazards for the walls.

[0004] An investigation revealed that a Chinese invention patent (publication number: CN114857704A) discloses a grain air conditioning device that recovers evaporated condensate and has a built-in ultrasonic atomizing plate. The device includes a heat exchanger, a blower, and a water tank. It also includes a water tank recess, an overflow outlet, a liquid level alarm switch, and an ultrasonic atomizing plate. The water tank has a recess in the middle for storing evaporated condensate and increasing space. The ultrasonic atomizing plate is detachably mounted on the bottom surface inside the recess for atomizing the liquid using ultrasound to achieve humidification. The liquid level alarm switch is movably mounted on the left side inside the recess for turning the humidification function on and off.

[0005] Although the aforementioned patent achieves condensate collection and humidification functions and is safe by redesigning the internal structure of the water tank of the grain air conditioner and improving the electrical control system, the moisture evaporated from the grain pile will condense into water droplets when it encounters the iron roof of the grain silo. The water droplets will flow into the grain along the silo wall, and the water droplets will concentrate at the edge of the grain pile, causing the grain at the edge to mold. If the condensate is collected and treated, not only can the problem of mold on the grain pile edge be solved, but the water source for the grain silo humidifier can also be replenished. However, this device does not have the ability to treat the condensate on the grain silo roof, and the treatment of roof condensate 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

[0013] As a preferred technical solution of this application, a limiting groove is formed on the side wall of the first U-shaped plate, and a limiting block is fixedly connected to the side wall of the second U-shaped plate, and the limiting block is slidably connected in the limiting groove.

[0014] As a preferred technical solution of this application, a rotating rod is provided above the mounting box, and a second pulley is coaxially fixed on both the rotating rod and the mounting shaft, and a second transmission belt is connected between the two second pulleys.

[0020] 2. By setting up striking blocks and brush plates to clean the dust on the dustproof screen, when the striking blocks abut against the partition, the striking blocks compress the spring. When the striking blocks separate from the partition, the spring returns to its original position, causing the striking blocks to strike the dustproof screen. At the same time, the rotating brush plates can clean the dust on the dustproof screen and prevent the dustproof screen from becoming clogged, so as not to affect the air passing through the wet film humidifier to humidify the grain in the grain silo.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides a buoy-type grain surface air conditioning humidifier, such as... Figures 1-10As shown, the technical solution includes a grain silo 1, a metal roof 9, and a wet film humidifier 20. The metal roof 9 is fixedly connected to the grain silo 1. A water supply pipe 4 is provided on the outer wall of the grain silo 1. A guide channel 36 is opened between the metal roof 9 and the water supply pipe 4. A water tank 8 is fixedly connected to the side wall of the grain silo 1. An 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 a UV sterilization device are provided at the inlet of the inlet pipe 18. The 5μm precision filter is a separation technology that efficiently intercepts micron-sized particles through filter media with specific pore sizes. The UV sterilization technology uses ultraviolet light to destroy the DNA / RNA structure of microorganisms, causing them to lose their reproductive ability and achieving non-chemical contact sterilization. The 5μm filter and the UV sterilization device are 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. The water tank 8 is equipped with a flow control mechanism, which includes a float ball 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 ball 16, and the connecting rod 30 is rotatably connected to the connecting plate 28. The condensate at the metal roof 9 is collected into the water tank 8 through the guide channel 36 and the water supply pipe 4. When the liquid level in the water tank 8 reaches the height of the float ball 16, the float ball 16 drives the metal ball 31 to abut against the metal blocks 29, which can drive the circulating water pump 17 and the first motor 12 to start, humidifying the grain in the grain bin 1. This not only solves the problem of mold on the edge of the grain pile caused by condensate, but also replenishes the water source for the wet film humidifier 20, and controls the timing of grain humidification.

[0035] The grain silo 1 has symmetrically arranged installation holes on its side wall, and an installation box 2 is fixedly connected to the installation holes. A dustproof net 5 is fixedly installed on the side wall of the installation box 2. A cleaning mechanism is provided between the dustproof net 5 and the installation box 2. The cleaning mechanism includes an installation 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 rods 42, and the round rods 42 are fixedly connected inside the installation plate 7. The dust on the dustproof net 5 is cleaned by the interaction of the striking blocks 26 and the brush plate 37. The spring 43 drives the striking blocks 26 to strike the dustproof net 5, and the brush plate 37 rotates to clean the dust on the dustproof net 5, preventing the dustproof net 5 from becoming clogged, so as not to affect the air passing through the wet film humidifier 20 to humidify the grain in the grain silo 1.

[0036] Reference Figure 2 , Figure 3 and Figure 5As shown, two metal blocks 29 are symmetrically fixed on the connecting plate 28. Two lead screws 25 are rotatably connected inside the water tank 8. Slider 27s are fixedly connected to both ends of the connecting plate 28, and the lead screws 25 pass through the sliders 27 and are threadedly connected to the sliders 27. Two third pulleys 32 are rotatably connected to the top of the water tank 8, and the third pulleys 32 are coaxially fixed with the lead screws 25. A third transmission belt 33 is connected between the two third pulleys 32. A circulating water pump 17 is provided inside the water tank 8, and the circulating water pump 17 is sealed to the outlet pipe 19. A guide plate 24 is provided below the inlet pipe 18. The guide plate 24 is fixedly connected inside the water tank 8. By setting the guide plate 24, the water entering the water tank 8 is prevented from hitting the float 16, causing the metal ball 31 to accidentally contact the metal block 29. A second motor 34 is fixedly connected to the top of the water tank 8. The output end of the second motor 34 is coaxially fixed with the lead screw 25.

[0037] In use, the second motor 34 is started, which drives the two lead screws 25 to rotate synchronously under the action of the third pulley 32 and the third transmission belt 33. The rotating lead screws 25 drive the slider 27 and the connecting plate 28 to move, which in turn drives the float 16 to rise and fall. The height of the float 16 is adjusted. The amount of moisture evaporation in the grain is estimated based on the area of ​​the grain silo 1 and the amount of grain piled up. The height of the float 16 in the water tank 8 is adjusted so that after a certain amount of moisture evaporates from the grain, the water in the water tank 8 can use buoyancy to push the float 16 to move, so that the metal ball 31 contacts the metal block 29, and timely humidifies the grain in the grain silo 1, avoiding the situation where too much moisture evaporates from the grain and water is not replenished in time, or where too little moisture evaporates and too much moisture is replenished.

[0038] Reference Figure 3 and Figure 8As shown, a protective net 10 is fixedly installed inside the mounting hole to protect the wet film humidifier 20 and prevent grain from entering the mounting hole. The wet film humidifier 20 is installed inside the mounting hole. A mounting frame 11 is fixedly connected inside the mounting box 2. A mounting shaft 35 is rotatably connected to one side of the mounting frame 11, 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. Both the first U-shaped plate 38 and the second U-shaped plate 40 are slidably connected inside the mounting plate 7. Multiple round rods 42 slide through the first U-shaped plate 38 and the second U-shaped plate 40 respectively. One end of multiple springs 43 is fixedly connected to the mounting plate 7. The other ends of multiple springs 43 are fixedly connected to the first U-shaped plate 38 and the second U-shaped plate 40 respectively. The side wall of the first U-shaped plate 38 is provided with a limiting groove 39, and the side wall of the second U-shaped plate 40 is fixedly connected with a limiting block 41, which is slidably connected in the limiting groove 39. The cross-section of the striking block 26 is set in an isosceles trapezoid. When the inclined surface of the striking block 26 is squeezed, it will push the striking block 26 to move towards the mounting plate 7. When any striking block 26 moves towards the mounting plate 7, under the action of the limiting block 41 and the limiting groove 39, it can drive the brush plate 37 to move towards the mounting plate 7. Multiple partitions 6 are fixedly connected to the side wall of the dustproof net 5, and the striking block 26 abuts against the partitions 6.

[0039] In use, rotating the mounting shaft 35 causes 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 towards 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 strike the dustproof net 5, thereby removing dust from the dustproof net 5 and preventing the dustproof net 5 from becoming clogged, so as not to affect the air passing through the wet film humidifier 20 to humidify the grain in the grain bin 1.

[0040] Reference Figure 4 and Figure 6As shown, a rotating rod 13 is provided above the mounting box 2. A second pulley 22 is coaxially fixed on both the rotating rod 13 and the mounting shaft 35. 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. The fan blade 21 is rotatably connected to the mounting frame 11. A first pulley 14 is coaxially fixed on both the fan blade 21 and the rotating rod 13. A first transmission belt 15 is connected between the two first pulleys 14. A connecting shell 3 is provided above the metal canopy 9. The end of the connecting shell 3 is fixedly connected to the mounting box 2. A first motor 12 is fixedly connected inside the connecting shell 3. The rotating rod 13 is rotatably connected inside the connecting shell 3. The output end of the first motor 12 is coaxially fixed to the connecting shell 3. Two metal blocks 29 are electrically connected to the circulating water pump 17 and the first motor 12. When the metal ball 31 abuts against the two metal blocks 29, the circuit of the circulating water pump 17 and the first motor 12 is closed.

[0041] In use, water droplets on the metal canopy 9 are collected and sent into the water tank 8, causing the liquid level in the water tank 8 to rise. 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 comes into contact with 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 delivers the water in the water tank 8 to the wet film humidifier 20 through the water outlet pipe 19. The first motor 12 drives the rotating rod 13 to rotate. The rotating rod 13 drives the fan blade 21 to rotate through the first pulley 14 and the first transmission belt 15, allowing air to pass through the wet film humidifier 20 and enter and exit the grain bin 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.

[0042] It should be noted that both the first motor 12 and the second motor 34 are connected to an external power supply via wires. 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 their start and stop. The external power supply is existing technology. The second motor 34 is a servo motor, and its output 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 existing technology in this field, so it will not be described in detail here.

[0043] In summary: During operation, the second motor 34 is started, which, under the action of the third pulley 32 and the third transmission belt 33, drives the two lead screws 25 to rotate synchronously. The rotating lead screws 25 drive the slider 27 and the connecting plate 28 to move, thereby driving the float 16 to rise and fall. Adjusting the height of the float 16, the water vapor evaporated from the grain in the grain bin 1 condenses into water droplets when it encounters the metal roof 9. The water droplets on the metal roof 9 flow into the water supply pipe 4 through the guide channel 36, and then 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 connecting rod 30... When the float ball 16 moves the metal ball 31 on the connecting rod 30, when the metal ball 31 abuts against 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 delivers the water in the water tank 8 to the wet film humidifier 20 through the water outlet pipe 19. The first motor 12 drives the rotating rod 13 to rotate. The rotating rod 13 drives the fan blade 21 to rotate through the first pulley 14 and the first transmission belt 15, so that the air passes through the wet film humidifier 20 and enters and exits the grain bin 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.

[0044] 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 plate 6, the striking block 26 drives the brush plate 37 to squeeze the spring 43 together and move towards the mounting plate 7. When the striking block 26 no longer contacts the partition plate 6, the spring 43 returns to its original position and pushes the striking block 26 to strike the dustproof net 5, thereby removing dust from the dustproof net 5.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
