Description

Technical Field

[0001] This invention relates to the field of ventilation, specifically to an energy-saving blower. Background Technology

[0002] In modern chicken farming, large-scale chicken flocks are raised in chicken houses, making environmental control within these houses crucial. Ventilation is one method of controlling the chicken house environment. In a closed environment, blowers are installed to extract air from the chicken house, creating negative pressure. Fresh air from outside then flows into the chicken house due to this pressure difference, providing the chickens with sufficient oxygen and helping them cool down. The blowers also remove stale air, keeping the chicken house dry and carrying away waste gases. However, a large amount of dust and feathers are also expelled with the stale air. Pathogens in the chicken house may be expelled with secretions, which dry and form fine particles that adhere to the dust. Marek's disease virus can also be found in the feathers of infected chickens. If these pathogens and viruses develop in one chicken house in a farm, then these pathogens and viruses will spread rapidly. The toxins will be discharged outside the chicken coop with the exhaust gas, causing large-scale cross-infection among chickens in different coops. Moreover, the odor inside the chicken coop will also be discharged outside. In large-scale farms, there are more than one chicken coop. These pathogens, viruses, and odors are discharged outside the chicken coop with the polluted air by the blowers, and then enter other chicken coops through their exhaust systems, causing infection in other chicken coops and affecting air quality. In the current exhaust technology, axial flow blowers are generally used to exhaust the chicken coop. Axial flow blowers have a simple structure, are easy to install, and have a large air volume, which is very suitable for the exhaust requirements of chicken coops. However, the axial flow blowers used in the current technology directly discharge the polluted gas from the chicken coop outside without treating the polluted gas, which leads to the above problems.

[0003] Therefore, in order to ensure that the air discharged by the blower is clean and odorless, prevent the spread of viruses in the chicken house, and improve the air quality of the farm, an energy-saving blower is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving blower that filters the exhaust gas by setting a filtration device, so that dust and feathers with attached viruses are retained in the chicken coop, thereby making the exhaust gas from the blower clean gas, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An energy-saving blower includes a blower duct. A motor is threadedly connected to the blower duct, and fan blades for exhaust are rotatably mounted on the motor. An installation plate is threadedly connected to the air inlet of the blower duct. A fixing plate and a fixing plate are threadedly connected above and below the air inlet on the installation plate, respectively. A protective plate is threadedly connected to the left end of the fixing plates and the right end of the fixing plates. Multiple rotating shafts are rotatably mounted on the fixing plate. Gears are keyed to the rotating shafts, and gears are keyed to the top of the rotating shafts. A motor is fixedly mounted on the installation plate. Gears are connected to the motor via a chain and synchronous belt. A filter is fitted onto the gear. When the blower is operating, [the following text appears to be unrelated and possibly a separate document:] chicken coop. Dust and chicken feathers inside the chicken house are collected at the air inlet of the ventilation duct by the airflow. The filter cotton filters and intercepts the dust and chicken feathers. By intercepting the dust and chicken feathers at the air inlet, the air discharged from the chicken house is ensured to be clean, preventing pathogens and viruses from spreading outside the chicken house through dust and chicken feathers and causing infection to the chickens outside the chicken house. When the dust and chicken feathers collect to a certain amount, they will clog the filter cotton, reducing the air intake of the exhaust fan. In order to ensure the exhaust volume inside the chicken house, motor two starts. Under the action of the chain, it drives gear two at the top of the rotating shaft to rotate. Gear two rotates the rotating shaft, which in turn rotates gear one. The rotation of gear one moves the filter cotton. The movement of the filter cotton moves the clean filter cotton to the air inlet, ensuring the exhaust volume inside the chicken house.

[0007] Preferably, a baffle is threadedly connected to the left side of the air inlet on the fixed plate 2, and a baffle is threadedly connected to the right side of the air inlet on the fixed plate 2. Both ends of the baffle 1 and baffle 2 are threadedly connected to a solenoid valve 1. A pressure plate 1 is movably mounted on each of the solenoid valve 1. A solenoid valve 2 is fixedly mounted on both the baffle 1 and baffle 2, located on one side of the air inlet. A pressure plate 2 is movably mounted on each of the solenoid valve 2. When the filter cotton filters the extracted air, solenoid valves 1 and 2 are closed. At this time, pressure plates 1 and 2 press the filter cotton tightly. This pressing of the filter cotton around the air inlet by pressure plates 1 and 2 ensures that the filter cotton is tightly attached, reducing the chance of fine dust entering the air duct and escaping outside the chicken coop through the gaps in the filter cotton installation. When the filter cotton needs to be replaced, the motor 2 starts, and both solenoid valves 1 and 2 open, causing pressure plates 1 and 2 to move away from the filter cotton, reducing the sliding friction of the filter cotton and ensuring smooth movement and replacement of the filter cotton.

[0008] Preferably, a filter chamber is formed between the second baffle and the first guard plate, and a cleaning chamber is formed between the second guard plate and the second guard plate. A rotating shaft 1 and a rotating shaft 2 are rotatably mounted on the second fixed plate and located within the cleaning chamber. A cam is fixedly mounted on each of the first and second rotating shafts. A gear 3 is mounted on the top of each of the first and second rotating shafts. The gear 3 is connected to the second motor via a synchronous belt. When the filter cotton is moved and replaced, the dirty filter cotton, which has absorbed dust and feathers, enters the cleaning chamber from the filter chamber under the pushing action of the gear 1. When the filter cotton passes through the first and second rotating shafts in the cleaning chamber, the gear 3, which is keyed to the first and second rotating shafts, causes the first and second rotating shafts to rotate under the chain drive of the second motor. The rotation of shaft one and shaft two causes the cams keyed to them to rotate. The rotation of the cams causes them to beat the dirty filter cotton that has moved to the cam position. The beating of the dirty filter cotton by the cams causes the filter cotton to vibrate. The vibration of the filter cotton causes the dust and feathers attached to it to fall off, thus cleaning the filter cotton. By cleaning the dirty filter cotton, it can be reused without frequent replacement, improving the working efficiency of the equipment and reducing labor costs. By setting gear three at the top of shaft one and shaft two, it can be directly driven by motor two without the need for additional drive equipment, simplifying the structure of the equipment and reducing the operating cost of the equipment.

[0009] Preferably, a rotating shaft three is fixedly installed between and above the two rotating shafts in the cleaning chamber. A roller is rotatably installed on the rotating shaft three. By setting the rotating shaft three, the filter cotton entering the cleaning chamber is not on the same straight line as the filter cotton in the filter chamber. When the cam vibrates and cleans the filter cotton in the cleaning chamber, the vibration of the filter cotton in the cleaning chamber is blocked by the rotating shaft three, ensuring that the vibration of the filter cotton in the cleaning chamber is not transmitted to the filter cotton in the filter chamber, causing the dust on the filter cotton to fall off and enter the exhaust fan and escape outside the chicken house.

[0010] Preferably, a protective plate three is fixedly installed between the fixed plate one and the fixed plate two, and the protective plate three covers the entire cleaning chamber. A protective plate four is fixedly installed at the front end of the baffle one, and a spring is installed inside the protective plate four. The spring connects the protective plate four and the pressure plate three, and the pressure plate three is in close contact with the filter cotton. A protective plate five is fixedly installed between the protective plate three and the protective plate four, and the protective plate five is in close contact with the filter cotton. When the filter cotton is moved and replaced, the spring inside the protective plate four keeps the pressure plate three in close contact with the filter cotton. By setting the spring to keep the pressure plate three in close contact with the filter cotton, dust and feathers are prevented from entering the cavity formed by the baffle one and the protective plate three through the gap between the protective plate three and the filter cotton, thus contaminating the clean filter cotton, reducing the amount of dust and feathers filtered by the filter cotton in the chicken house, and improving the use effect of the filter cotton.

[0011] Preferably, the fixing plate 2 is threaded with multiple guide plates 1. The guide plates 1 are installed on both sides of the filter cotton. The right end of the fixing plate 2 is fixedly installed with guide plates 2 and 3. The gap between guide plates 2 and 3 allows the filter cotton to pass through. By setting guide plates 2 and 3, when installing the filter cotton, the filter cotton is passed through the gap between guide plates 2 and 3, and under the limiting action of guide plates 2 and 3, the filter cotton directly enters the gear 1. The rotation of the gear 1 causes the filter cotton to move. The moving filter cotton enters the guide rail formed by the guide plates 1 and continues to move forward in the guide rail to the next gear 1. By setting the guide rail formed by the guide plates 1, when installing the filter cotton, only the front end of the filter cotton needs to be placed into the gap between guide plates 2 and 3. The filter cotton can be automatically installed by the gear 1 and guide plates 1 without disassembling the equipment, which reduces the manual operation cost.

[0012] Preferably, a collection box is threadedly connected to the lower part of the fixing plate and to one side of the cleaning chamber. A filter bag is installed in the collection box. When the dust and feathers on the dirty filter cotton are vibrated and cleaned, the dust and feathers vibrated off the dirty filter cotton are collected on the collection box and the filter bag. Then the filter bag is removed and the dust and feathers are centrally processed. By setting up the collection box and filter bag, the dust and feathers in the room can be collected and centrally processed, thus cleaning the air in the chicken house.

[0013] Preferably, the collection box is connected to the air duct via an exhaust pipe. The exhaust pipe is connected to the air inlet of the air duct. Since dust and feathers are relatively light, it would take a long time for them to fall freely. Therefore, by setting an exhaust pipe at the bottom of the collection box and the air inlet of the air duct, the suction at the air inlet is used to quickly draw the scattered dust into the filter bag, thereby accelerating the collection of dust and feathers and preventing dust and feathers from floating in the cleaning chamber for a long time and adhering to the inner wall of the cleaning chamber, which would affect the cleaning effect of the filter cotton.

[0014] Preferably, the cleaning chamber is threaded with a baffle three, which is threaded onto a fixed plate two, and its two ends are respectively connected to the baffle two and the guide plate one. A germicidal lamp is threaded onto the side of the baffle three near the mounting plate. When the dirty filter cotton is vibrated and cleaned, dust and feathers are scattered in the cleaning chamber, and both the dirty filter cotton and the cleaned filter cotton are in the cleaning chamber. After the filter cotton is cleaned by the vibration of the cam, it moves to the other side of the baffle three. At this time, the germicidal lamp sterilizes the cleaned filter cotton. In order to prevent the dust and feathers that are cleaned from adhering to the clean filter cotton, the baffle three is set so that the dust and feathers that are cleaned will not adhere to the clean filter cotton, thereby affecting the filtration effect of the filter cotton. The germicidal lamp installed on the side of the baffle three near the mounting plate can kill most of the bacteria remaining on the filter cotton, thereby preventing pathogens and viruses from multiplying and breeding on the filter cotton, and then being drawn out of the chicken house by the blower, causing infection to the chickens outside the chicken house.

[0015] Preferably, a pressure detector is threadedly connected to the baffle and located in the filter chamber. When the filter cotton collects a certain amount of dust and feathers, the filter pores of the filter cotton will be blocked, resulting in a reduction in ventilation. In order to ensure the ventilation of the chicken house, the pressure detector is set to detect the change in air pressure in the filter chamber and replace the filter cotton in time. When the filter cotton is blocked, the airflow velocity in the filter chamber decreases and the air pressure increases. When the pressure detector detects the increase in air pressure, it controls the second motor to rotate to replace the filter cotton.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The energy-saving blower of the present invention, by setting filter cotton at the air inlet of the blower, filters dust and feathers, so that the exhaust air is clean air, preventing pathogens and viruses from spreading outside the chicken house through dust and feathers and infecting the chickens outside the chicken house, thereby improving the virus prevention and control effect of the chicken farm.

[0018] 2. The energy-saving blower of the present invention, by setting a rotating shaft, an air pressure detector and a motor, when the blower is working, dust and feathers in the chicken house continuously accumulate at the filter cotton, causing the filter cotton to become clogged. The air pressure detector detects the air pressure change in the filter chamber and controls the replacement device to automatically replace the filter cotton. The automatic replacement of the filter cotton ensures the ventilation in the chicken house and prevents the chickens from being harmed due to insufficient ventilation.

[0019] 3. The energy-saving blower described in this invention uses two rotating shafts to drive a cam to rotate. The rotating cam beats and vibrates the dirty filter cotton that has been adsorbed with dust and feathers. The beating and vibration remove the dust and feathers from the filter cotton, thus cleaning it. This cleaning allows the filter cotton to be recycled within the equipment, saving on the cost of using the filter cotton. Attached Figure Description

Therefore, the feathers in the collection box 36 are processed and the filter bag 37 is replaced weekly, as detailed below:

[0030] An energy-saving blower includes a blower 3, a motor 1 internally threaded into the blower 3, fan blades 2 rotatably mounted on the motor 1 for ventilation, a mounting plate 4 threadedly connected to the air inlet of the blower 3, a fixing plate 5 and a fixing plate 6 threadedly connected above and below the air inlet on the mounting plate 4 respectively, a guard plate 7 threadedly connected to the left end of the fixing plate 5 and the fixing plate 6, and a guard plate 8 threadedly connected to the right end of the fixing plate 5 and the fixing plate 6, multiple rotating shafts 18 rotatably mounted on the fixing plate 5, gears 15 keyedly connected to each rotating shaft 18, and gears 15 keyedly connected to the top of the rotating shafts 18, a motor 2 14 fixedly mounted on the mounting plate 4, gears 2 16 connected to the motor 2 14 via a synchronous belt, and a filter cotton 19 sleeved on the gears 15.

Gear 3 17 is connected to motor 2 14 via a synchronous belt. Shaft 3 28 is fixedly installed between and above the two rotating shafts 18 in the cleaning chamber 25. Roller 29 is rotatably installed on shaft 3 28. Guard plate 3 9 is fixedly installed between fixed plate 1 5 and fixed plate 2 6, covering the entire cleaning chamber 25. Guard plate 4 30 is fixedly installed at the front end of baffle 1 10. Spring 40 is installed inside guard plate 4 30. Spring 40 connects guard plate 4 30 and pressure plate 3 31. Pressure plate 3 31 is in close contact with filter cotton 19. Guard plate 5 32 is threadedly connected between guard plate 3 9 and guard plate 4 30.

[0031] Specific workflow.

[0032] During operation, motor 14 is started, causing gear 16 to rotate via a synchronous belt. The rotating shaft 18, keyed to gear 16, rotates, causing gear 15 to rotate. Once gear 15 starts rotating, guard plate 8 is opened, and filter cotton 19 is pushed through the gap between guide plate 34 and guide plate 35. Filter cotton 19 passes through the gap and enters the synchronous belt, connecting with synchronous belt 1. The rotation of gear 15 causes synchronous belt 1 to move filter cotton 19 forward. The filter cotton 19 is installed on both sides. The guide plate 33 causes the filter cotton 19 to move forward along the guide rail formed by the guide plate 33. Under the action of the guide plate 33, the filter cotton 19 will not deviate from the moving path. During the movement of the filter cotton 19, the solenoid valve 20 and the solenoid valve 21 are in the open state. When the filter cotton 19 reaches the air inlet of the air duct 3 of the filter chamber 24, the motor 14 shuts off, the gear 15 stops rotating, and the solenoid valves 20 and 21 close, causing the pressure plate 22 and the pressure plate 23 to press the filter cotton 19 tightly. After the filter cotton 19 is pressed tightly, the motor... When motor 1 is started, it rotates fan blade 2. The rotation of fan blade 2 forces polluted air from inside the chicken coop through filter cotton 19 and out through air duct 3. Simultaneously, air from the cleaning chamber 25 is also drawn out through the exhaust pipe 38. Dust and feathers in the polluted air are trapped by the filter cotton 19, resulting in clean air discharged from air duct 3. This prevents pathogens and viruses from spreading outside the chicken coop through dust and feathers. When the filter cotton 19 in the filter chamber 24 traps a certain amount of dust and feathers... Afterwards, the filter pores of the filter cotton 19 become clogged, reducing the air intake and increasing the flow rate in the filter chamber 24. At this point, when the air pressure detector 39 detects that the air pressure has increased to 150 kPa, solenoid valve 20 and solenoid valve 21 open, and pressure plates 22 and 23 loosen their pressure on the filter cotton 19. Then, control motor 14 starts to drive the rotating shaft 18, causing gear 15 to rotate. Through the rotation of gear 15, the filter cotton 19, which adsorbs dust and feathers, begins to move to the cleaning chamber 25. The moving speed of the filter cotton 19 is set to 0.The speed is 1 m / s, and the movement time is 10 seconds. After passing through the third rotating shaft 28, it reaches the first rotating shaft 26 and the second rotating shaft 27. Under the action of the cam 41, the dirty filter cotton 19 is beaten and vibrated, causing dust and feathers to fall off the filter cotton 19. The fallen dust and feathers are quickly collected on the filter bag 37 of the collection box 36 by the action of the suction pipe 38. The clean filter cotton 19 moves to the inlet of the second guide plate 34 and the third guide plate 35. Under the action of the rotation of the first gear 15, it moves to the baffle 13 near the safety gate. On one side of the mounting plate 4, when motor 2 14 starts, the germicidal lamp 11 simultaneously starts to sterilize the cleaned filter cotton 19. When motor 2 14 stops, the germicidal lamp 11 stops. The filter cotton 19, after being sterilized by the germicidal lamp 11, continues to participate in the next round of filtration. The filter bag 37 in the collection box 36 is set to be cleaned and replaced weekly. The collection box 36 is opened, the filter bag 37 is removed, a clean filter bag 37 is replaced, and the collection box 36 is reinstalled. At this point, the entire equipment is working.

[0033] Example 2, as Figures 1 to 8 As shown, in this embodiment, the blower is installed in the chicken house where chicks are raised. Since chicks molt a lot, the collection box 36 is processed and the filter bag 37 is replaced every three days, as detailed below:

[0034] In chicken houses where chicks are raised, chicks grow and develop quickly and can complete a molt within 15 days. Therefore, there is a lot of shed feathers in the chicken house. In order to deal with these feathers in a timely manner and ensure the air quality in the chicken house, the collection box 36 is cleaned and the filter bag 37 is replaced every three days.

[0035] For any implementation methods not mentioned in Example 2, they are the same as in Example 1, and will not be described in detail here.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
