Description

Technical Field

[0001] The invention relates to the technical field of grain depot ventilation, and in particular to an energy-saving grain depot ventilation and dust removal adjustment system. Background Art

[0002] In the past, grain warehouse ventilation mainly relied on natural ventilation or simple mechanical ventilation equipment. However, natural ventilation was limited by weather conditions, and it was difficult to ensure the stability and controllability of the ventilation effect. Early mechanical ventilation equipment often had limited performance and could not meet the ventilation needs of large-scale grain warehouses. With the continuous development of grain storage technology, the requirements for grain warehouse ventilation are getting higher and higher. Centrifugal fans have gradually become the mainstream choice for grain warehouse ventilation due to their unique performance advantages.

[0003] At present, the centrifugal fan used in grain warehouse ventilation has its air inlet end in the axial direction of the fan and its air outlet end in the radial direction of the fan, which means that the air enters along the axial direction of the fan and then blows out in the radial direction perpendicular to the axis. This method is usually suitable for situations where the demand for wind pressure is large and the demand for air volume is small. In order to ensure the dust removal effect during ventilation, a filter is generally installed in the axial direction to filter the dust. At the same time, a scraper is used to repeatedly scrape the dust on the filter to avoid clogging of the filter. However, when the space of the grain warehouse is large, it is necessary to achieve fast and large-scale ventilation. When the accumulated air is ventilated, a larger air volume is required. Although this requirement can be achieved by controlling the reverse rotation of the centrifugal impeller through a motor, the radially installed filter cannot filter the dust and clean the filter as well as the above-mentioned axial filtration. In addition, the filter is frequently scratched repeatedly, which will cause the mesh of the filter to deform and break, reducing its filtration accuracy and failing to effectively block fine dust particles, thereby weakening the overall filtration effect and having an adverse effect on the ventilation quality of the grain warehouse, thereby affecting its service life, increasing the cost of use, and affecting the subsequent filtration effect.

[0004] Therefore, it is necessary to provide an energy-saving grain warehouse ventilation and dust removal adjustment system to solve the above problems. Summary of the invention

[0011] One of the fixing seats is fixedly connected to the centrifugal fan and the air inlet duct respectively, and the other fixing seat is fixedly connected to the adapter seat. A motor is fixedly mounted on the fixing seat near one end of the adapter seat.

[0012] As a further improvement of the above scheme, the spray assembly includes a movable disk rotatably connected to the top of the cyclone separator, the cyclone separator is internally rotatably connected to a driving disk, a connecting rod is evenly fixedly connected between the movable disk and the driving disk, four sliders are slidably connected to the inside of the driving disk, the sliders are all slidably connected to fixed rods, the fixed rods are all fixedly connected to the inner wall of the driving disk, the four sliders are fixedly connected to the adjacent ends of the nozzles, the inner side of the fixed tube is slidably connected to a sliding sleeve, the outer side of the sliding sleeve is symmetrically fixedly connected to sliding rods, the inner side of the movable disk is fixedly connected to a movable sleeve, the inner wall of the movable sleeve is provided with two partial spiral grooves, and the sliding rods are all slidably connected to the partial spiral grooves.

[0013] As a further improvement of the above scheme, a worm gear is rotatably connected inside the air intake duct, a gear sleeve is fixedly connected to one end of the sealing ring sleeve close to the centrifugal fan, a worm is fixedly connected to one end of the mounting shaft located inside the centrifugal fan, and the worm gear is meshingly connected to the worm and the gear sleeve respectively.

[0014] As a further improvement of the above solution, the outer wall of the sealing ring sleeve is evenly provided with through grooves connected to the air intake duct, and the outer wall of the centrifugal fan is provided with an annular groove matched with the gear sleeve.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The motor can not only drive the movable seat to rotate, thereby controlling the connection between the radial part of the centrifugal fan and the exhaust duct and the cyclone separator, but also regulate the sealing component to achieve the sealing of the axial part of the centrifugal fan and the connection with the cyclone separator. When the radial part of the centrifugal fan is connected to the cyclone separator, the sealing component will prompt the axial part of the centrifugal fan to open. At this time, the centrifugal fan will inlet air radially and exhaust air axially. This mode can meet the needs of rapid and large-area ventilation when the grain warehouse space is large. Compared with traditional ventilation methods, this mode can achieve large-area air exchange in a shorter time, improve ventilation efficiency, and reduce ventilation time, thereby reducing the risk of grain deterioration due to untimely ventilation. When the radial part of the centrifugal fan is connected to the exhaust duct, the centrifugal fan will be inlet air radially and exhaust air axially. This mode can meet the needs of rapid and large-area ventilation when the grain warehouse space is large. Compared with traditional ventilation methods, this mode can achieve large-area air exchange in a shorter time, improve ventilation efficiency, and reduce ventilation time, thereby reducing the risk of grain deterioration due to untimely ventilation. When the pipelines are connected, the sealing assembly will realize the axial connection between the centrifugal fan and the cyclone separator. At this time, the centrifugal fan can intake air axially and exhaust air radially. This mode is suitable for grain storage with long air ducts and large resistance. Compared with previous ventilation designs, this mode can provide greater wind pressure, effectively overcome air duct resistance, ensure that air can penetrate into every corner of the grain storage, ensure uniformity and comprehensiveness of ventilation, and no matter which ventilation method is used, dust can be removed through the cyclone separator, and the cyclone separator can use the rotation of the centrifugal fan to drive the air flow to achieve dust removal, which greatly reduces energy loss. Compared with the method of separately configuring dust removal equipment in the prior art, this integrated design saves equipment cost and space, and reduces energy consumption caused by the operation of additional equipment.

[0021] 2. When the centrifugal fan is radially connected to the cyclone separator, the axial air intake from the centrifugal fan can enter the Venturi tube radially, and through the control of the solenoid valve at the bottom of the water pipe, based on Bernoulli's principle, the Venturi tube can draw water from the water tank and make it enter the fixed pipe. At the same time, the sliding sleeve in the fixed pipe will drive the movable disk and the driving disk to rotate, and the rotation of the driving disk will push the four sliders, thereby realizing the sealing of the bottom of the fixed pipe. In this way, the water entering the fixed pipe can only be sprayed out from the inside, thereby realizing the flushing of the inner wall of the cyclone separator. BRIEF DESCRIPTION OF THE DRAWINGS

When the straight groove of the movable seat 702 is connected with the fixed seat 701, the airflow generated by the operation of the centrifugal fan 3 can smoothly enter the cyclone separator 4 through the straight groove, thereby achieving ventilation and dust-containing gas separation operations. In this process, the separated impurities will naturally fall into the collecting barrel 10.

[0056] Axial sealing and ventilation mode switching: With the help of the transmission action between the worm 606 and the worm wheel 605, the sealing ring 604 and the sealing disk 603 are driven to rotate, so as to realize the axial sealing or opening operation of the centrifugal fan 3, and then complete the switching of the ventilation mode. When the actual demand is a larger wind pressure and a smaller air volume, the axial sealing is completed, and the centrifugal fan 3 is radially connected with the cyclone separator 4, so that the air flows into the centrifugal fan 3 through the radial direction; when a larger air volume and a smaller wind pressure are required, the axial direction is opened, and the centrifugal fan 3 is axially connected with the cyclone separator 4, so that the air flows into the centrifugal fan 3 through the axial direction.

[0057] Spray cleaning work: When there is a need to clean the inner wall of the cyclone separator 4, open the solenoid valve at the bottom of the water pipe 804 in the connecting assembly, and switch the ventilation mode to a larger wind pressure and a smaller air volume. At this time, start the centrifugal fan 3 to intake air from the axial direction. The generated airflow will generate negative pressure when passing through the venturi tube 803, thereby sucking water in the water tank 5 into the fixed pipe 802. The water flow will push the sliding sleeve 909 to move, and the sliding rod 910 on the sliding sleeve 909 will slide in the partial spiral groove of the movable sleeve 902, thereby driving the movable disk 901 and the driving disk 903 to rotate. The slider 905 inside the driving disk 903 will not only drive the nozzle 908 to rotate, but also realize the sealing of the bottom of the fixed tube 802, so that the water flow is sprayed out through the nozzle 908, realizing an all-round flushing valve for the inner wall of the cyclone separator 4.
