[0002] The star-shaped discharger is used to be installed at the discharge port of the discharger working under negative pressure. The upper part receives the material discharged by the discharger, and relies on the rotating impeller to convey the material. It also plays a sealing role to prevent air from being sucked in from the discharge port during pneumatic conveying, ensuring the normal discharge of the discharger. As a special unloading equipment, it plays a great role in cleaning and washing work. It is often used in dust removal systems as one of the important equipment of dust removal systems, and it is particularly suitable for dust and small particles.

[0003] In the prior art, the star-shaped discharger for dust collector needs to be cleaned regularly during use. However, when removing the impeller of the existing star-shaped discharger, the impeller needs to be taken out from the side of the star-shaped discharger. Since the impeller is mostly made of metal and is heavy, and the internal operating space of the star-shaped discharger is small, it is not convenient for the operator to take out the impeller. Disassembly is troublesome and inconvenient for personnel to operate, the work efficiency is low, and the practicability is not strong.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a star-shaped discharger for a dust collector. Utility Model Content

[0020] like Figure 1-3As shown, the utility model provides a star-shaped discharger for a dust collector, comprising a shell 1 and a front cover 2 and a rear cover 3 respectively arranged on both sides of the shell 1, a side of the front cover 2 is connected to a connecting plate 11, and the other side of the connecting plate 11 is connected to a motor 4, and two sides of the shell 1 adjacent to the rear cover 3 are symmetrically provided with sliding components 6, and the sliding component 6 includes a fixed block 601 connected to the position of the side of the shell 1 near the front cover 2 and the rear cover 3, and a sliding rod 602 is slidably arranged in the fixing block 601, and the sliding rod 602 is away from the rear cover. One end of the end cover 3 is connected to a limit ring 606, a sealing cover 5 is connected to the outer side of the rear end cover 3, and a connecting block 605 is arranged on the outer side of the sealing cover 5 at a position corresponding to the fixing block 601, an end of the sliding rod 602 close to the sealing cover 5 is inserted into the connecting block 605 and is slidably connected to the connecting block 605, and the end of the sliding rod 602 is located at the side of the connecting block 605 away from the rear end cover 3 and is connected to a threaded column 603, a nut 604 is threadedly connected to the threaded column 603, and the sliding rod 602 is located at the connecting block 605 close to the rear end cover 3 The side of the impeller 9 is provided with a fixing ring 607, and the effect is that when the impeller 9 needs to be cleaned, the fastening bolt 501 is first removed from the sealing cover 5, the fixing of the sealing cover 5 and the rear end cover 3 is cancelled, and the handle 8 is held and pulled outward, so that the sealing cover 5 and the bearing 7 move outward synchronously, thereby driving the rotating shaft 10 and the impeller 9 to move outward, and at the same time, the sealing cover 5 drives the connecting blocks 605 on both sides to move outward, and under the limiting action of the nut 604, the connecting block 605 drives the slide bar 602 to move between the fixing block 60 1 slides from the inside to the outside. When the impeller 9 moves to the outside of the housing 1 as a whole, the limit ring 606 arranged at the end of the slide bar 602 away from the connecting block 605 abuts against the side of the fixing block 601 close to it, thereby preventing the slide bar 602 from being separated from the fixing block 601. The impeller 9 is synchronously and smoothly moved outward through the sliding components 6 arranged on both sides of the housing 1, which is convenient for personnel to clean. In addition, the supporting force generated by the sliding component 6 on the impeller 9 saves the force of personnel when taking out the impeller 9, which is convenient for personnel to operate and improves work efficiency.

[0021] The output shaft of the motor 4 passes through the connecting plate 11 and the front end cover 2 to the inside of the casing 1 and is connected to a rotating shaft 10, and the rotating shaft 10 is located inside the casing 1 and is connected to an impeller 9, a bearing 7 is installed at the center position of the sealing cover 5, and the other end of the rotating shaft 10 passes through the bearing 7 to the outside of the sealing cover 5 and is connected to a handle 8.

[0022] A plurality of fastening bolts 501 are arranged on the side of the sealing cover 5 away from the rear end cover 3. The fastening bolts 501 ensure the airtightness between the sealing cover 5 and the rear end cover 3, and facilitate the disassembly of the sealing cover 5 by the later personnel, thereby facilitating the cleaning or replacement of the impeller 9.

[0023] The diameter of the impeller 9 is smaller than the inner diameter of the rear end cover 3 , thereby ensuring that the impeller 9 is not hindered by the rear end cover 3 when moving toward the outside of the housing 1 , and facilitating quick removal of the impeller 9 .

[0024] The diameters of the nut 604 and the fixing ring 607 are both larger than the diameter of the through hole on the connecting block 605, and the diameter of the limiting ring 606 is larger than the diameter of the through hole on the fixing block 601, thereby ensuring that the connecting block 605 and the sliding rod 602 are firmly connected, improving the stability when removing the impeller 9, and by setting the limiting ring 606, it is ensured that the sliding rod 602 will not separate from the fixing block 601 when sliding the sliding rod 602 outward, ensuring the normal use of the device.

[0025] The surface of the handle 8 is provided with anti-slip textures. By providing the anti-slip textures on the surface of the handle 8, the friction force on the surface of the handle 8 is increased, making it easier for people to grip firmly and reducing the risk of sliding.

[0026] Working principle: When the impeller 9 needs to be cleaned, first remove the fastening bolt 501 from the sealing cover 5, cancel the fixation between the sealing cover 5 and the rear end cover 3, hold the handle 8 and pull it outward, so that the sealing cover 5 and the bearing 7 move outward synchronously, thereby driving the rotating shaft 10 and the impeller 9 to move outward, and at the same time, the sealing cover 5 drives the connecting blocks 605 on both sides to move outward, and under the limiting action of the nut 604, the connecting block 605 drives the sliding rod 602 to slide outward in the fixing block 601, and when the impeller 9 moves to the outside of the shell 1 as a whole, the limiting ring 606 set at the end of the sliding rod 602 away from the connecting block 605 hits the fixing block 601 close to it. The side surface is prevented from the slide bar 602 being separated from the fixed block 601. The sliding components 6 arranged on both sides of the shell 1 make the impeller 9 move smoothly and synchronously to the outside, which is convenient for personnel to clean. The supporting force generated by the sliding component 6 on the impeller 9 saves the force of personnel when taking out the impeller 9, which is convenient for personnel to operate and improves work efficiency. When the impeller 9 needs to be replaced, the above operation is repeated to move the impeller 9 out of the outside of the shell 1, and then the nut 604 is removed from the threaded column 603, and the fixation of the connecting block 605 and the slide bar 602 is cancelled, so that the sealing cover 5, the rotating shaft 10 and the impeller 9 are disassembled, which is convenient for personnel to replace the impeller 9 and improves practicality.
