[0016] The present invention provides a double-intake adjustable guide vane high-efficiency sulfuric acid blower, which has the following beneficial effects:

[0017] 1. The air intake chamber of the present invention is composed of two separate and independent air intake boxes to eliminate the mutual interference of the intake airflows, and guide vanes are arranged on both sides of the impeller. When the airflow enters from the air intake box, the inclined guide vanes are used to pre-deflect the airflow before it contacts the impeller, thereby avoiding the airflow from causing a large impact interference to the impeller. At the same time, when it is necessary to adjust the angle of the guide vane according to the demand, it is only necessary to control the rotation of the worm through the stabilizing component, and the worm wheel will drive the double gear ring to rotate inside the casing through the transmission shaft and the driving gear, so that all the driven gears drive the guide vanes to deflect through the adjusting shaft at the same time, so that the airflow enters the impeller at an ideal angle, thereby improving the intake efficiency and impeller efficiency, and meeting the requirements of different working conditions.

[0018] 2. According to the present invention, when the worm rotates, the rotation of the screw sleeve can be limited by the limit groove and the limit plate, so as to control the horizontal movement of the screw sleeve on the worm. At this time, the indicator plate will be driven to move on the scale, so that when adjusting the angle of the guide vane, there is a certain reference vertebra to improve the accuracy of the adjustment process. At the same time, the limit groove will limit the stroke of the limit plate, thereby limiting the maximum rotation angle of the guide vane to avoid over-rotation of the guide vane during adjustment. Before adjustment, the positioning rod and the positioning hole can be used to place the baffle at the specified scale. Therefore, during the adjustment process, there is no need to observe while adjusting, and the worm can be rotated mindlessly. When the indicator plate moves to the specified position, the baffle will limit the indicator plate from continuing to move, and the worm can no longer be rotated, making the adjustment faster.

[0019] 3. Before the present invention is rotated, one side of the hand wheel can be pulled or the other side of the hand wheel can be pushed. At this time, the movable end gear discs on the outer sides of the left and right transmission sleeves can be separated from the fixed end gear discs in the fixed sleeve through the push rod. At this time, when the hand wheel is turned, the worm gear will be driven to rotate through the transmission sleeve and the transmission column to control the working state of the adjustment component. After adjustment, when the hand is released, the spring will squeeze the movable end gear disc to make it engage with the fixed end gear disc. At this time, the position of the hand wheel can be limited, thereby avoiding accidental rotation of the hand wheel to cause the guide vane angle to deflect, which is beneficial to enhance the stability of the guide vane after adjustment.

[0020] 4. The present invention can rotate the iron handle before adjustment to make it fit and absorb with the magnet on one side. At this time, the driving plate can drive the sliding column to slide in the straight groove on the top surface of the control box, thereby driving the gear sleeve to move horizontally through the limit sleeve to connect the ends of the two worms. Therefore, when the hand wheel on one side is turned, the two worms will rotate at the same time through the tooth groove and the gear sleeve, so that the angles of the guide blades on both sides can be adjusted at the same time, which is beneficial to improve the efficiency of adjustment. When the guide blades do not need to be adjusted at the same time according to needs, it is only necessary to rotate the handle to make it fit and absorb with the other magnet. At this time, the driving plate, sliding column and limit sleeve will drive the gear sleeve to separate from one of the worms, so that the two worms will not rotate synchronously, and they can be quickly switched to meet different usage requirements.

[0032] The specific operation is as follows: when adjusting, first pull the hand wheel 1103 on one side or push the hand wheel 1103 on the other side, then the movable end toothed disc 1106 on the outer side of the transmission sleeve 1102 on the left and right sides can be separated from the fixed end toothed disc 1108 in the fixed sleeve 1101 through the push rod 1104, and then when the hand wheel 1103 is turned, the worm 1201 will be driven to rotate through the transmission sleeve 1102 and the transmission column 1105, and the worm wheel 1202 will drive the transmission shaft 1203 and the driving gear 1204 to rotate. The double tooth ring 1205 rotates inside the casing 1, so that all the driven gears 1206 drive the guide vanes 1208 to deflect through the adjustment shaft 1207 at the same time, so that the airflow enters the impeller 404 at an ideal angle, thereby improving the intake efficiency and the efficiency of the three-dimensional flow impeller 404 to meet the requirements of different working conditions.

At this time, two separate and independent air intake box suction chambers are used to eliminate mutual interference of the intake air flow, and when the air flow enters the casing 1, the inclined guide vane 1208 is used to make the air flow pre-deflected before contacting the impeller 404, thereby avoiding the air flow from causing a large impact interference to the impeller 404.

[0034] The specific operation is as follows. Before use, use the positioning rod 1308 and the positioning hole 1309 to place the baffle 1307 at the specified scale, and then turn the iron handle 1401 to make it fit and adsorb with the magnet 1402 on one side. At this time, the driving plate 1403 can drive the sliding column 1404 to slide in the straight groove on the top surface of the control box 10, so as to drive the gear sleeve 1406 to move horizontally through the limiting sleeve 1405 to connect the ends of the two worms 1201. Therefore, when the worm 1201 rotates, the limiting groove 1304 and the limiting plate 1303 can limit the rotation of the screw sleeve 1302, so that the screw sleeve 1302 can be controlled to move horizontally on the worm 1201 through the thread groove 1301. At this time, the indicator plate 1305 will be driven to move on the scale 1306, so that when adjusting the angle of the guide vane 1208, there is a certain reference vertebra to improve the accuracy of the adjustment process. When the indicator plate 1305 moves to the specified position, the baffle 1307 will limit the indicator plate 1305 from moving further, and the worm 1201 can no longer be rotated. Therefore, during the adjustment process, there is no need to adjust and observe at the same time, which is more convenient. When the worm 1201 rotates, the two worms 1201 will also rotate at the same time through the tooth groove 1407 and the gear sleeve 1406, so that the angles of the guide blades 1208 on both sides can be adjusted at the same time, which is beneficial to improve the efficiency of adjustment. When there is no need to adjust the guide blades 1208 at the same time, it is only necessary to turn the handle 1401 so that it fits and adsorbs with the other magnet 1402. At this time, the drive plate 1403, the sliding column 1404, and the limit sleeve 1405 will drive the gear sleeve 1406 to separate from one of the worms 1201, so that the two worms 1201 will not rotate synchronously, and they can be quickly switched to meet different usage requirements.

[0035] In summary, when using this double-intake adjustable guide vane high-efficiency sulfuric acid blower, first, use the positioning rod 1308 and the positioning hole 1309 to place the baffle 1307 at the specified scale, and then turn the iron handle 1401 to make it fit and adsorb with the magnet 1402 on one side, then the driving plate 1403 can drive the sliding column 1404 to slide in the straight groove on the top surface inside the control box 10, so as to drive the gear sleeve 1406 to move horizontally through the limiting sleeve 1405 to connect the ends of the two worm gears 1201, and then pull the handwheel 1103 on one side or push the handwheel 1103 on the other side, at this time, the movable end gear disc 1106 on the outer side of the transmission sleeve 1102 on the left and right sides can be connected with the fixed end gear disc 1101 in the fixed sleeve 1101 through the top rod 1104. 08 is separated.

Then, when the worm 1201 rotates, the limiting groove 1304 and the limiting plate 1303 can limit the rotation of the screw sleeve 1302, so that the screw sleeve 1302 can be controlled to move horizontally on the worm 1201 through the thread groove 1301, and at this time, the indicator plate 1305 will be driven on the scale 1306. The guide vanes 1208 can be adjusted by the hand wheel 1103, and the guide vanes 1208 can be adjusted by the hand wheel 1103.

Then, after adjustment, let go, and the spring 1107 will squeeze the movable end gear disc 1106 to make it engage with the fixed end gear disc 1108. At this time, the position of the hand wheel 1103 can be limited, so as to avoid accidental rotation of the hand wheel 1103 causing the angle of the guide vane 1208 to deflect. Finally, the external driving source is connected to one end of the main shaft 401 through the coupling to drive the main shaft 401 to work. At this time, the support bearing box group 2, the support sliding bearing 3, the thrust sliding bearing 5 and the thrust bearing box group 6 are used to support and limit the main shaft 401, so that negative pressure is formed at both ends of the casing 1 through the impeller 404.
