Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, in particular to a hollow brick mixing and stirring equipment capable of improving the void ratio. Background Art

[0002] The raw material processing of hollow bricks usually includes crushing, mixing and aging. In actual production, the crushed raw materials are usually added with water during the mixing process. The purpose of mixing is to fully mix the various raw materials. The purpose of adding water is to promote the dissolution of the raw materials and soften the powder to improve the quality of the hollow brick products. The current hollow brick mixing equipment has the following shortcomings:

[0003] 1. When using the mixing equipment, water is added all at once. Part of the raw material absorbs a large amount of water, and the water is unevenly distributed, which makes mixing difficult and the quality of mixing is deviated;

[0004] 2. The raw materials added to the mixing equipment are not screened, so relatively large raw material particles will be mixed in the raw materials, affecting the quality of hollow brick production.

[0005] Therefore, it is necessary to design a hollow brick mixing and stirring equipment that can improve the void ratio to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a hollow brick mixing and stirring device with improved void ratio.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A hollow brick mixing and stirring device for improving the void ratio comprises a mixing barrel, a plurality of supporting feet are fixedly connected to the lower side wall of the mixing barrel, a feeding pipe and a discharging pipe are respectively connected to the top and the side wall of the mixing barrel, a material box is connected to the upper end of the feeding pipe, a water leakage port is provided on the top of the mixing barrel, a water tank is fixedly connected to the outer top of the mixing barrel, the bottom of the water tank is connected to the water leakage port, a fixing plate is provided on the side wall of the water tank, a motor is fixedly connected to the upper wall of the fixing plate, a stirring rod is fixedly connected to the output shaft of the motor, the stirring rod sequentially penetrates the fixing plate and the top of the mixing barrel and extends to the bottom of the mixing barrel, a plurality of stirring blades are evenly spaced on the side wall of the stirring rod located in the mixing barrel, a control mechanism is provided in the water tank, and a screening mechanism is provided in the feeding pipe.

[0010] Preferably, the screening mechanism includes a sieve mesh fixedly connected to the inner wall of the blanking pipe. A first bevel gear is fixedly connected to the side wall of the stirring rod outside the stirring barrel. A vertical plate is fixedly connected to the lower wall of the fixing plate. A rotating shaft is provided through the side wall of the vertical plate. One end of the rotating shaft penetrates the side wall of the blanking pipe and extends into the blanking pipe. A rotating rod is fixedly connected to one end of the rotating shaft located inside the blanking pipe.

DETAILED DESCRIPTION OF THE INVENTION

[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.

[0021] Referring to Figure 1-2 , a hollow brick mixing and stirring device for increasing the void ratio, including a stirring barrel 1. The bottom of the stirring barrel 1 is set as an inclined plane. In order to facilitate the outflow of the stirred material from the discharge pipe 4 and prevent residues inside, a plurality of support feet 2 are fixedly connected to the lower side wall of the stirring barrel 1. The top and side wall of the stirring barrel 1 are respectively communicated with a feeding pipe 12 and a discharge pipe 4. The upper end of the feeding pipe 12 is communicated with a material box 11. The top of the material box 11 is provided with a feeding port. The top of the stirring barrel 1 is provided with a water leakage port 8. The outer top of the stirring barrel 1 is fixedly connected with a water tank 3. The top of the water tank 3 is provided with a water filling port. The bottom of the water tank 3 is communicated with the water leakage port 8. The side wall of the water tank 3 is provided with a fixing plate 10. The upper wall of the fixing plate 10 is fixedly connected with a motor 9. The output shaft of the motor 9 is fixedly connected with a stirring rod 6. The stirring rod 6 sequentially passes through the fixing plate 10 and the top of the stirring barrel 1 and extends to the bottom of the stirring barrel 1. A plurality of stirring blades 5 are equidistantly arranged on the side wall of the stirring rod 6 located inside the stirring barrel 1. A control mechanism is arranged in the water tank 3, and a screening mechanism is arranged in the feeding pipe 12.

[0022] The control mechanism includes a moving plate 7 arranged at the bottom of the water tank 3. The moving plate 7 fits with the inner bottom of the water tank 3 to prevent water from flowing into the water leakage port 8 through the gap between the moving plate 7 and the water tank 3. The moving plate 7 is provided with an opening, and the caliber of the opening is the same as that of the water leakage port 8. Moreover, when the cam 17 pushes the moving plate 7 to the innermost position, the opening just coincides with the water leakage port 8 up and down. One end of the moving plate 7 passes through the side wall of the water tank 3. A sealing ring is arranged at the penetration of the moving plate 7 and the water tank 3 to avoid water leakage from the water tank 3. One end of the moving plate 7 located inside the water tank 3 is elastically connected with the inner wall of the water tank 3 through a spring. The cam 17 cooperates with the spring, and the moving plate 7 will reciprocate, and water will flow into the stirring barrel 1 intermittently. The side wall of the stirring rod 6 located outside the stirring barrel 1 is fixedly connected with a cam 17. The moving plate 7 and the cam 17 are in the same plane.

[0023] The screening mechanism includes a screen 13 fixedly connected to the inner wall of the feeding pipe 12. The screen 13 is made of a flexible material. The side wall of the stirring rod 6 located outside the stirring barrel 1 is fixedly connected with a first bevel gear. The lower wall of the fixing plate 10 is fixedly connected with a vertical plate 16. A rotating shaft 14 is arranged through the side wall of the vertical plate 16. One end of the rotating shaft 14 passes through the side wall of the feeding pipe 12 and extends into the feeding pipe 12. One end of the rotating shaft 14 located inside the feeding pipe 12 is fixedly connected with a rotating rod 15. When the rotating rod 15 rotates, it continuously beats the screen 13, and the raw materials will fall faster after being screened on the screen 13. The end of the rotating shaft 14 away from the rotating rod 15 is fixedly connected with a second bevel gear. The first bevel gear meshes with the second bevel gear.

[0024] In the present invention, raw materials and water are respectively added into the material box 11 and the water tank 3, and then the motor 9 is started. The output shaft of the motor 9 will drive the stirring rod 6 to rotate. The rotation of the stirring rod 6 will drive the stirring blades 5 to rotate, so as to stir the raw materials in the stirring barrel 1. The first bevel gear on the stirring rod 6 drives the second bevel gear to rotate, so that the rotating shaft 14 drives the rotating rod 15 to rotate. The rotating rod 15 will intermittently beat the flexible screen 13. The up-and-down shaking of the screen 13 will accelerate the falling of the raw materials into the stirring barrel 1. The large-particle raw materials are screened on the screen 13. The rotation of the rotating rod 15 will also accelerate the falling of the raw materials from the material box 11 into the feeding pipe 12.

[0025] The rotation of the stirring rod 6 will cause the cam 17 to intermittently push the moving plate 7 into the water tank 3, so that the opening on the moving plate 7 faces the water leakage port 8, and the water will flow down. When the cam 17 does not squeeze the moving plate 7, the spring will push the moving plate 7 back to the initial position, and the water will stop flowing in. In this way, intermittent water addition during stirring will enable the raw materials and water to be fully mixed, avoiding difficult stirring caused by uneven water absorption of the raw materials and accelerating the stirring rate and quality.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
