Description

Technical Field

[0001] The present invention relates to the technical field of mixers, and particularly to a fine mixer for wear-resistant materials for the inner lining of thermal energy equipment. Background Art

[0002] The inner lining materials of thermal energy equipment (such as boilers, heat exchangers, etc.) need to have excellent wear resistance, high temperature resistance and corrosion resistance.

[0003] In the production process of traditional inner lining materials, an ordinary mixer is usually used for mixing. However, in the area near the mixing cylinder wall during mixing, the material flow rate is relatively slow because the mixing effect of the mixing paddle in the central area is stronger, and the area near the cylinder wall is less directly affected by the paddle, resulting in insufficient mixing of the material here with the material in the central area. It is difficult for an ordinary mixer to achieve uniform mixing of the materials, resulting in unstable performance of the inner lining materials, affecting the service life and efficiency of thermal energy equipment. In addition, during the process of transporting materials to the mixer, the materials cannot quickly disperse in the mixing cylinder, and the materials are prone to accumulation and jamming. For this reason, we propose a fine mixer for wear-resistant materials for the inner lining of thermal energy equipment to solve the above problems. Summary of the Invention

Detailed implementation manners

[0018] 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.

[0019] The embodiments of the present invention provide three technical solutions, specifically including the following embodiments: Embodiment 1: Please refer to Figures 1 - 4 , a fine mixer for wear-resistant materials for the inner lining of a thermal energy device, including a cylinder body 1, a cylinder cover 2 is arranged at the top of the cylinder body 1, a stirring rod 3 is rotatably connected to the bottom of the cylinder cover 2, and a rotary shrinking stirring mechanism 4 is arranged between the bottom end of the stirring rod 3 and the bottom wall of the cylinder body 1. The rotary shrinking stirring mechanism 4 is used for stirring and mixing the materials close to the cylinder wall; The rotary contraction stirring mechanism 4 includes a mounting seat 41 fixed on the bottom wall of the cylinder body 1. Five sleeves 42 are fixed on the mounting seat 41. A contraction arm 43 is slidably connected inside each of the five sleeves 42. A limit post 44 is fixed at the top of each of the five contraction arms 43. A gear 45 is rotatably connected to the top of the mounting seat 41. Five arc grooves 46 are formed through the top of the gear 45. The arc grooves 46 are adapted to the size of the limit posts 44. The top ends of the five limit posts 44 all penetrate through the arc grooves 46 and extend to the outside of the arc grooves 46. The outer surface of the limit post 44 is slidably connected to the inner surface of the arc groove 46. The bottom end of the stirring rod 3 is fixed to the top of the gear 45. A stirring plate 48 is rotatably connected to the top of each of the five contraction arms 43 through a rotating rod 47. The stirring plate 48 is fixed on the rotating rod 47. A first motor 49 is fixed at the bottom of the contraction arm 43. The first motor 49 is a three-phase asynchronous motor, which can rotate forward and backward, is controlled by an external switch, and is electrically connected to an external power supply. The first motor 49 drives the rotating rod 47 and the stirring plate 48 to rotate. The output end of the first motor 49 is fixed to the bottom end of the rotating rod 47.

[0020] Through the setting of the rotary contraction stirring mechanism 4, while using the stirring rod 3 to stir, it can synchronously drive the five stirring plates 48 to expand close to the cylinder wall or contract away from the cylinder wall. And during this process, the five stirring plates 48 stir simultaneously, which can fully and evenly stir the wear-resistant materials in the area close to the cylinder wall, solving the problems that the direct action of the paddle on the area near the cylinder wall is small, the mixing of the materials here and the materials in the central area is insufficient, and it is difficult for ordinary mixers to achieve uniform mixing of the materials.

[0021] A box cover 5 is fixed between the tops of the five contraction arms 43. The setting of the box cover 5 is to prevent materials from entering the arc grooves 46 and causing jamming of the gear 45. The bottom end of the stirring rod 3 penetrates through the box cover 5 and extends to the outside of the box cover 5. The outer surface of the stirring rod 3 is rotatably connected to the inner surface of the box cover 5. A second motor 6 is fixed to the top of the cylinder cover 2.

[0022] The second motor 6 drives the stirring rod 3 to rotate. The second motor 6 is controlled by an external switch and is electrically connected to an external power supply. The second motor 6 is a three-phase asynchronous motor that can rotate forward and backward. The output end of the second motor 6 is fixed to the top of the stirring rod 3 through a coupling. A plurality of stirring paddles 7 are fixed on the outer surface of the stirring rod 3. A polytetrafluoroethylene coating layer is hermetically arranged on both the stirring rod 3 and the stirring paddles 7. This coating layer is tightly pasted and wrapped around the stirring rod 3 and the stirring paddles 7. This coating layer plays an anti-corrosion and anti-wear role. It directly transmits the stirring impact to the stirring rod 3 and the stirring paddles 7, so it is not easy to form cracks and corrosion pinholes, and can effectively prevent and avoid the infiltration of corrosive reaction media, having an ideal anti-corrosion and anti-wear effect. At the same time, this coating layer utilizes the excellent corrosion resistance, super wear resistance and wide high and low temperature adaptability of polytetrafluoroethylene, making the stirrer almost able to withstand the corrosion of all chemical substances. This structure not only enables the stirrer to have a higher stirring intensity, but also can effectively prevent corrosion and resist wear, having a longer service life. The stirring paddle 7 is made of ceramic material, and the surface of the paddle blade is flat or curved. Since the stirring paddle 7 uses ceramic blades, the paddle blades obtain excellent wear resistance, corrosion resistance, high temperature resistance properties, as well as high hardness and high compressive strength. Sometimes, the ceramic paddle blades with flat or curved surfaces can adapt to a variety of stirring media with a wider adaptability. A feed pipe 8 is connected to the top of the cylinder cover 2, and the top end of the feed pipe 8 is connected to a hopper 9. External wear-resistant materials enter the cylinder body 1 through the hopper 9.

[0023] Embodiment 2: On the basis of Embodiment 1, as shown in Figures 5 - 6 As shown, an up-and-down vibration assembly 10 is arranged between the stirring rod 3 and the cylinder wall of the cylinder body 1. The up-and-down vibration assembly 10 includes a runner 101 fixed on the stirring rod 3. A wave groove 102 is formed in the runner 101. Two fixing plates 103 are fixed on the cylinder wall of the cylinder body 1. A first spring 104 is fixed to the top of each of the two fixing plates 103. A cross plate 105 is fixed between the top ends of the two first springs 104. The arrangement of the first spring 104 enables the cross plate 105 to be reset.

[0024] A side plate 106 is fixed to one side of the cross plate 105. A connecting rod 107 is fixed to one side of the side plate 106. One end of the connecting rod 107 extends into the wave groove 102. The outer surface of the connecting rod 107 is slidably connected to the inner surface of the wave groove 102. When the runner 101 rotates, the wave groove 102 rotates, and thus the connecting rod 107 slides up and down in the wave groove 102.

[0025] A rotary material spreading unit 11 is arranged on the transverse plate 105. The rotary material spreading unit 11 is used to quickly spread the materials discharged from the feed pipe 8 in the cylinder body 1. The rotary material spreading unit 11 includes a mounting plate 111 fixed to the top of the transverse plate 105. A vertical rod 112 is rotatably connected to the top of the mounting plate 111. A third motor 113 is fixed to the bottom of the mounting plate 111. The third motor 113 is controlled by an external switch and is electrically connected to an external power supply. The third motor 113 drives the vertical rod 112 to rotate. The output end of the third motor 113 is fixed to the bottom end of the vertical rod 112 through a coupling.

[0026] A material spreading cone 114 is fixed to the top end of the vertical rod 112. The arrangement of the material spreading cone 114 can disperse the materials. The top end of the material spreading cone 114 extends into the interior of the feed pipe 8. A round box 115 is fixed to the outer surface of the vertical rod 112. Through holes 116 are formed through the inner wall of the round box 115. The arrangement of the through holes 116 allows the materials to be thrown out by centrifugal force.

[0027] Through the combined use of the up-and-down vibration assembly 10 and the rotary material spreading unit 11, when the up-and-down vibration assembly 10 vibrates up and down, it can drive the material spreading cone 114 to penetrate into the feed pipe 8 to quickly stab the materials, accelerating the feeding speed. At the same time, after the materials fall onto the material spreading cone 114, they can be quickly spread out. By utilizing the rotation of the round box 115, the materials are thrown out by centrifugal force, enabling the materials to be evenly dispersed in the cylinder body 1, thereby avoiding the phenomenon of material accumulation and material jamming.

[0028] Example 3: On the basis of Example 2, as shown in Figures 6 - 7 A scraping component 12 is arranged on the feed pipe 8 to scrape the materials that closely adhere to the inner wall of the round box 115 during rotation into the through holes 116. The scraping component 12 includes a fixed seat 121 fixed to one side of the feed pipe 8. A vertical groove 122 is formed inside the fixed seat 121. A sliding plate 123 is slidably connected to the inner surface of the vertical groove 122. A scraping plate 124 is fixed to the bottom of the sliding plate 123. The arrangement of the scraping plate 124 allows the materials on the inner wall of the round box 115 to be scraped into the through holes 116 for discharge. The bottom of the scraping plate 124 extends into the interior of the round box 115, and one side of the scraping plate 124 is slidably connected to the inner wall of the round box 115. A second spring 125 is fixed between the top of the sliding plate 123 and the inner wall of the vertical groove 122.

[0029] Through the arrangement of the scraping component 12, the materials that closely adhere to the inner wall of the round box 115 during the rotation of the round box 115 can be scraped by the scraping plate 124 into the through holes 116, accurately realizing the quick throwing out and spreading of the materials.

[0030] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] During operation, pour the wear-resistant material raw materials into the hopper 9, and then they fall into the cylinder body 1. Start the second motor 6, and the second motor 6 drives the stirring rod 3 and the stirring paddle 7 to rotate. The stirring paddle 7 stirs and mixes the raw materials. At the same time, the stirring rod 3 drives the gear 45 to rotate. Then, when the gear 45 rotates, the five limit posts 44 slide in the arc grooves 46, thereby driving the five contraction arms 43 to radially expand outwards, and then driving the five stirring plates 48 to approach the inner wall of the cylinder body 1. Start the first motor 49 to drive the stirring plates 48 to rotate. When the contraction arms 43 expand and extend to the maximum stroke, the second motor 6 rotates in reverse, driving the five contraction arms 43 to contract, and then driving the stirring plates 48 away from the inner wall. During the process of the expansion and contraction of the stirring plates 48, the raw materials at the outer edge close to the inner wall can be fully stirred. When the stirring rod 3 rotates, it synchronously drives the runner 101 to rotate, thereby driving the connecting rod 107 to slide up and down in the wave groove 102, and then driving the side plate 106 and the cross plate 105 to reciprocate up and down, and then driving the material spreading cone 114 to reciprocate up and down, so that the material spreading cone 114 reciprocally pokes the material into the feed pipe 8, thereby accelerating the falling speed of the material. At the same time, the raw materials falling on the material spreading cone 114 automatically spread outwards, and part of the raw materials fall into the round box 115. Start the third motor 113, and the third motor 113 drives the vertical rod 112 to rotate, thereby driving the round box 115 to rotate. Then, the materials in the round box 115 are pressed against the inner wall of the round box 115 by centrifugal force. With the scraping of the scraping plate 124, the raw materials on the inner wall of the round box 115 are thrown out through the through holes 116 for a wider range of material spreading.

[0032] The above has described the embodiments of the invention in detail, but the above content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
