Description

Technical Field

[0001] The utility model relates to the technical field of desulfurizer processing, and specifically, to a novel mixing device for emulsified desulfurizer. Background Technique

[0002] Desulfurizer generally refers to a reagent for removing free sulfur or sulfur compounds in fuels, raw materials or other materials. In the control and treatment of pollutants, it mainly refers to a reagent that can remove sulfur oxides in waste gas. Various alkaline compounds can be used as desulfurizers. The desulfurizer for removing sulfur dioxide in flue gas is mostly cheap lime, limestone and alkaline solutions prepared with lime-based reagents. In the process of desulfurizer processing, solid materials need to be mixed with liquid materials. To improve the mixing efficiency between materials, the materials are often put into the mixing device for stirring and mixing. Since the solid materials are prone to caking when contacting the liquid materials, it is difficult to crush the caked materials only by stirring and mixing, which affects the processing of emulsified desulfurizer. In view of this, we propose a novel mixing device for emulsified desulfurizer. Summary of the Invention

[0003] The purpose of the utility model is to provide a novel mixing device for emulsified desulfurizer to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, one of the purposes of the utility model is to provide a novel mixing device for emulsified desulfurizer, including a stirring cylinder. A plurality of filter plates are fixedly arranged inside the stirring cylinder. A stirring mechanism is arranged inside the stirring cylinder. The stirring mechanism is used to cooperate with the filter plates to crush the caked materials. The stirring mechanism includes a rotating shaft rotatably connected inside the stirring cylinder. A plurality of stirring components are fixedly arranged on the circumferential surface of the rotating shaft along its axial direction. The stirring components are composed of a plurality of stirring rods fixedly arranged on the circumferential surface of the rotating shaft. When the stirring rod is at the lowest position, its bottom contacts the upper surface of the filter plate. The cross-section of the stirring rod is triangular. When the stirring rod rotates, it is used to stir and mix the materials and change the internal flow direction of the materials. A transmission mechanism is arranged on the upper surface of the stirring cylinder. The transmission mechanism is used to drive the rotating shaft to rotate.

[0005] As a further improvement of the technical solution, a top block is fixedly arranged on the circumferential surface of one end of the top of the rotating shaft penetrating through the upper surface of the stirring cylinder. A limiting ring is rotatably connected to the middle of the upper surface of the stirring cylinder. The limiting ring is coaxially sleeved outside the rotating shaft. The upper surface of the limiting ring is provided with a stepped inclined surface with different slopes from low to high and then decreasing. The top block is slidably connected to the upper surface of the limiting ring. When the top block rotates and slides along the upper surface of the limiting ring, the rotating shaft moves up and down.

[0006] As a further improvement of the technical solution, a fixing ring is fixedly arranged at a position near the middle on the upper surface of the mixing drum. The fixing ring is coaxially sleeved outside the limiting ring. A coil spring is coaxially sleeved between the limiting ring and the fixing ring. The inner end and the outer end of the coil spring are respectively fixedly arranged on the surfaces of the limiting ring and the fixing ring. The coil spring is used to drive the limiting ring to rotate and reset.

[0007] As a further improvement of the technical solution, an installation frame is fixedly arranged on the upper surface of the mixing drum. A motor is fixedly arranged on the top of the installation frame. The output shaft of the motor is coaxially driven and connected with a cross-shaped insertion rod through a coupling. The motor is used to drive the cross-shaped insertion rod to rotate.

[0008] As a further improvement of the technical solution, the cross-shaped insertion rod is coaxially and slidably connected to the top of the rotating shaft. The rotating cross-shaped insertion rod is used to drive the rotating shaft to rotate. A compression spring is coaxially sleeved outside the cross-shaped insertion rod. The two ends of the compression spring are respectively fixedly arranged on the surfaces of the cross-shaped insertion rod and the rotating shaft. The compression spring is used to drive the rotating shaft to descend and reset.

[0009] As a further improvement of the technical solution, a plurality of scraping plates are fixedly arranged at the bottom of the circumferential surface of the rotating shaft. When the rotating shaft is at the lowest position, the bottom of the scraping plate is in close contact with the inner bottom wall of the mixing drum. The scraping plate is used to scrape the materials at the bottom of the mixing drum. A limiting rod is fixedly arranged in the middle of the inner bottom wall of the mixing drum. The rotating shaft is coaxially rotatably connected to the circumferential surface of the limiting rod. The limiting rod is used to limit the position of the bottom of the rotating shaft.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. In the novel mixing device for emulsified desulfurizer, during the process of mixing materials, the rotating shaft drives the stirring rod to rotate and drives the stirring rod to lift and lower. Cooperating with the filter plate, the caked solid materials can be ground and crushed, so as to improve the mixing effect of subsequent solid materials and liquid materials.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0021] Please refer to Figures 1-4 As shown, one of the purposes of this embodiment is to provide a new type of mixing device for emulsified desulfurizer, including a mixing drum 1. A plurality of filter plates 11 are fixedly arranged inside the mixing drum 1. A mixing mechanism 2 is arranged inside the mixing drum 1. The mixing mechanism 2 is used to cooperate with the filter plates 11 to crush caked materials. A transmission mechanism 3 is arranged on the upper surface of the mixing drum 1. The transmission mechanism 3 is used to drive the rotating shaft 21 to rotate. The mixing mechanism 2 includes a rotating shaft 21 rotatably connected inside the mixing drum 1. A plurality of mixing components are fixedly arranged on the circumferential surface of the rotating shaft 21 along its axis direction. The mixing components are composed of a plurality of mixing rods 22 fixedly arranged on the circumferential surface of the rotating shaft 21. When the mixing rod 22 is at the lowest position, the bottom of it contacts the upper surface of the filter plate 11. The cross section of the mixing rod 22 is triangular. When the rotating shaft 21 rotates, the rotating rotating shaft 21 drives the mixing rod 22 to rotate. Since the cross section of the mixing rod 22 is triangular, the mixing rod 22 is used to stir and mix the materials and change the internal flow direction when rotating. During the rotation of the mixing rod 22, the mixed solution is guided to flow upward through its inclined surface to cooperate with the filter plate 11 to continuously disperse the materials, so that the materials inside the mixing drum 1 are mixed with each other, thereby improving the mixing effect of the materials.

[0022] Meanwhile, a plurality of scraping plates 23 are fixedly arranged at the bottom of the circumferential surface of the rotating shaft 21. When the rotating shaft 21 is at the lowest position, the bottom of the scraping plate 23 is in close contact with the inner bottom wall of the mixing cylinder 1. When the rotating shaft 21 rotates, it drives the scraping plate 23 to rotate, and the scraping plate 23 scrapes the materials at the bottom of the mixing cylinder 1 away from the bottom of the mixing cylinder 1, so as to facilitate the discharge of the materials from the mixing cylinder 1. At the same time, in order to improve the stability of the rotating shaft 21 during rotation, a limiting rod is fixedly arranged in the middle of the inner bottom wall of the mixing cylinder 1, and the rotating shaft 21 is coaxially rotatably connected to the circumferential surface of the limiting rod, and the position of the bottom of the rotating shaft 21 is restricted by the limiting rod to improve the stability of the rotating shaft 21 during rotation.

[0023] An installation frame 31 is fixedly arranged on the upper surface of the mixing cylinder 1, and a motor 32 is fixedly arranged on the top of the installation frame 31. The output shaft of the motor 32 is coaxially driven and connected with a cross-shaped inserting rod 33 through a coupling. The motor 32 is used to drive the cross-shaped inserting rod 33 to rotate. The cross-shaped inserting rod 33 is coaxially and slidably connected to the top of the rotating shaft 21. When the motor 32 works, it drives the cross-shaped inserting rod 33 to rotate. During the rotation of the cross-shaped inserting rod 33, it drives the rotating shaft 21 to rotate. A compression spring 34 is coaxially sleeved outside the cross-shaped inserting rod 33, and both ends of the compression spring 34 are fixedly arranged on the surfaces of the cross-shaped inserting rod 33 and the rotating shaft 21 respectively. The compression spring 34 is used to drive the rotating shaft 21 to descend and reset.

[0024] A top block 24 is fixedly arranged on the circumferential surface of one end of the top of the rotating shaft 21 passing through the upper surface of the mixing cylinder 1. A limiting ring 25 is rotatably connected to the middle of the upper surface of the mixing cylinder 1. The limiting ring 25 is coaxially sleeved outside the rotating shaft 21. The upper surface of the limiting ring 25 is provided with a stepped inclined surface with different slopes from low to high and then decreasing. The top block 24 is slidably connected to the upper surface of the limiting ring 25. The top block 24 rotates and slides along the upper surface of the limiting ring 25 to lift and lower the rotating shaft 21. The initial position of the top block 24 is located in the middle area of the limiting ring 25. The rotating rotating shaft 21 drives the top block 24 to rotate. The bottom of the top block 24 is in contact with the inclined surface with a larger slope at a higher position of the limiting ring 25. As the rotating shaft 21 rotates, the top block 24 moves along the upper inclined surface, so that the rotating shaft 21 and the top block 24 rise. When the top block 24 moves to the top area of the limiting ring 25, as the rotating shaft 21 continues to rotate, the top block 24 separates from the limiting ring 25, and the elastic force of the compression spring 34 drives the rotating shaft 21 to descend to the bottom area of the limiting ring 25, so that the bottom of the stirring rod 22 is in contact with the upper surface of the filter plate 11. The rotating stirring rod 22 cooperates with the filter plate 11 to crush the agglomerated materials, which is convenient for the subsequent mixing of the materials. As the rotating shaft 21 rotates, the bottom of the top block 24 is in contact with the inclined surface with a smaller slope at a lower position of the limiting ring 25, so that the top block 24 moves along the lower inclined surface to drive the rotating shaft 21 to rise to the middle area of the limiting ring 25, so that the stirring rod 22 is away from the filter plate 11, avoiding the long-term contact and friction between the filter plate 11 and the stirring rod 22 and shortening the service life.

[0025] To prevent the position where the stirring rod 22 descends and contacts the filter plate 11 from always being the same area, a fixing ring 26 is fixedly installed at a position near the middle on the upper surface of the mixing drum 1. The fixing ring 26 is coaxially sleeved outside the limiting ring 25. A coil spring 27 is coaxially sleeved between the limiting ring 25 and the fixing ring 26. The inner end and the outer end of the coil spring 27 are respectively fixedly installed on the surfaces of the limiting ring 25 and the fixing ring 26. When the rotating top block 24 contacts the inclined surface of the limiting ring 25, it drives the limiting ring 25 to rotate, and at the same time makes the coil spring 27 wind up. As the winding degree of the coil spring 27 increases, the required force gradually increases, resulting in a decrease in the rotation speed of the limiting ring 25. Therefore, when the rotation speed of the limiting ring 25 decreases, the top block 24 moves along the inclined surface of the limiting ring 25. And as the top block 24 and the limiting ring 25 are used, the frictional force between their contact surfaces is different. Therefore, the winding degree of the coil spring 27 by the rotation of the limiting ring 25 is different, so that the contact area between the stirring rod 22 and the filter plate 11 changes when the stirring rod 22 descends, which can reduce the damage between the stirring rod 22 and the filter plate 11 and extend the service life. When the top block 24 separates from the limiting ring 25, the coil spring 27 drives the limiting ring 25 to rotate and reset, facilitating the secondary use of the limiting ring 25 later.

[0026] In summary, the working principle of this solution is as follows: An inlet pipe driving a sealing cover is fixedly installed on the upper surface of the mixing drum 1. Open the sealing cover, pour solid materials and liquid materials into the interior of the mixing drum 1 through the inlet pipe, close the sealing cover, make the motor 32 work, drive the rotating shaft 21 to rotate through the cross-shaped insertion rod 33. When the rotating shaft 21 rotates, it drives the stirring rod 22 to rotate. Stir and mix the materials inside the mixing drum 1 through the stirring rod 22. Since the cross-section of the stirring rod 22 is triangular, during the rotation of the stirring rod 22, the mixed solution is guided to flow upward through its inclined surface, so that the mixed solution flows upward to cooperate with the filter plate 11 to continuously disperse the materials, making the materials inside the mixing drum 1 mix with each other, thereby improving the mixing effect of the materials.

[0027] During the process of the rotating shaft 21 and the stirring rod 22 rotating to stir and mix the materials, the initial position of the top block 24 is located in the middle area of the limit ring 25. The rotating rotating shaft 21 drives the top block 24 to rotate. The bottom of the top block 24 contacts the inclined surface with a larger inclination at a higher position of the limit ring 25. As the rotating shaft 21 rotates, the top block 24 moves along the upper inclined surface, so that the rotating shaft 21 and the top block 24 rise. When the top block 24 moves to the top area of the limit ring 25, as the rotating shaft 21 continues to rotate, the top block 24 separates from the limit ring 25, and the elastic force of the compression spring 34 drives the rotating shaft 21 to descend, so that the bottom of the stirring rod 22 contacts the upper surface of the filter plate 11. The rotating stirring rod 22 cooperates with the filter plate 11 to crush the agglomerated materials, which is convenient for the subsequent mixing of the materials. After the materials are crushed for a period of time, as the rotating shaft 21 rotates, the bottom of the top block 24 contacts the inclined surface with a smaller inclination at a lower position of the limit ring 25, so that the top block 24 moves along the lower inclined surface and drives the rotating shaft 21 to rise to the middle area of the limit ring 25, so that the stirring rod 22 moves away from the filter plate 11, avoiding the filter plate 11 and the stirring rod 22 contacting and rubbing for a long time and shortening the service life;

[0028] When the material mixing is completed, a discharge pipe with a discharge valve inside is fixedly arranged at the bottom of the circumferential surface of the mixing drum 1. The discharge valve is opened, and the materials inside the mixing drum 1 are discharged through the discharge pipe. When the rotating shaft 21 is in the lowest position, the bottom of the scraper 23 contacts the inner bottom wall of the mixing drum 1. When the rotating shaft 21 rotates, it drives the scraper 23 to rotate, and the materials at the bottom of the mixing drum 1 are scraped away from the bottom of the mixing drum 1 by the scraper 23, so as to facilitate the discharge of the materials from the mixing drum 1.
