Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and in particular to a mixing equipment for hollow bricks that improves the void ratio. Background Technology

[0002] The raw material processing for hollow bricks typically includes crushing, mixing, and aging. In actual production, water is usually added during the mixing process after the crushed raw materials are crushed. The purpose of mixing is to ensure that the various raw materials are thoroughly mixed, while adding water is to promote the disintegration of the raw materials and soften the powder, thereby improving the quality of the finished hollow bricks. Current hollow brick mixing equipment has the following shortcomings:

[0003] 1. During the use of the mixing equipment, water is added all at once. Some of the raw materials absorb a large amount of water, resulting in uneven water distribution, which makes mixing difficult and leads to deviations in the quality of the mixture.

[0004] 2. The raw materials added to the mixing equipment are not screened, so there will be relatively large raw material particles mixed in, which will affect the quality of hollow bricks produced.

[0005] Therefore, it is necessary to design a mixing and stirring device for hollow bricks that can improve the void ratio to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hollow brick mixing and stirring device that improves the void ratio.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mixing device for improving the void ratio of hollow bricks includes a mixing drum. Multiple support legs are fixedly connected to the lower side wall of the mixing drum. A feed pipe and a discharge pipe are respectively connected to the top and side wall of the mixing drum. A material box is connected to the upper end of the feed pipe. A drain outlet is provided at the top of the mixing drum. A water tank is fixedly connected to the outer top of the mixing drum. The bottom of the water tank is connected to the drain outlet. 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 passes through the fixing plate and the top of the mixing drum and extends to the bottom of the mixing drum. Multiple stirring blades are evenly spaced on the side wall of the stirring rod inside the mixing drum. A control mechanism is provided inside the water tank, and a screening mechanism is provided inside the feed pipe.

[0009] Preferably, the control mechanism includes a movable plate disposed at the bottom of the water tank, the movable plate having an opening, one end of the movable plate penetrating through the side wall of the water tank, the end of the movable plate located inside the water tank being elastically connected to the inner wall of the water tank via a spring, and the stirring rod being fixedly connected to a cam on the side wall outside the stirring tank.

[0010] Preferably, the screening mechanism includes a screen fixedly connected to the inner wall of the feed pipe, a first bevel gear fixedly connected to the side wall of the stirring rod outside the stirring tank, a vertical plate fixedly connected to the lower wall of the fixed plate, a rotating shaft passing through the side wall of the vertical plate, one end of the rotating shaft passing through the side wall of the feed pipe and extending into the feed pipe, a rotating rod fixedly connected to the end of the rotating shaft inside the feed pipe, and a second bevel gear fixedly connected to the end of the rotating shaft away from the rotating rod.

[0011] Preferably, the top of the material box is provided with a feeding port, and the top of the water tank is provided with a water filling port.

[0012] Preferably, the movable plate is fitted to the inner bottom of the water tank, and the movable plate and the cam are in the same plane.

[0013] Preferably, the first bevel gear meshes with the second bevel gear, and the opening has the same diameter as the drain outlet.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention is equipped with a control mechanism. During stirring, the cam on the stirring rod will intermittently push the moving plate into the water tank, so that the water in the water tank will intermittently flow into the stirring bucket from the opening. In this way, the intermittent addition of water during stirring will make the raw materials and water fully mixed, avoid the difficulty of stirring due to uneven water absorption of the raw materials, and speed up the stirring rate.

[0016] 2. This invention features a screening mechanism. The rotating shaft causes the rotating rod to beat the screen, accelerating the dropping of raw materials for screening. Large particles of raw materials will not fall into the mixing tank. The rotation of the rotating rod also prevents the raw materials from clogging the feed pipe, thereby improving the quality of raw material mixing and enhancing the practicality of the equipment.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-2 A hollow brick mixing and stirring device for improving the void ratio includes a mixing tank 1. The bottom of the mixing tank 1 is set as an incline to facilitate the flow of the mixed material from the discharge pipe 4 and prevent residue inside. Multiple support legs 2 are fixedly connected to the lower side wall of the mixing tank 1. The top and side wall of the mixing tank 1 are respectively connected to the feed pipe 12 and the discharge pipe 4. The upper end of the feed pipe 12 is connected to the material box 11. The top of the material box 11 is provided with a feeding port. The top of the mixing tank 1 is provided with a drain outlet 8. The outer top of the mixing tank 1 is fixed. A water tank 3 is connected, with a water inlet at the top and a drain outlet 8 at the bottom. A fixing plate 10 is provided on the side wall of the water tank 3, and a motor 9 is fixedly connected to the upper wall of the fixing plate 10. A stirring rod 6 is fixedly connected to the output shaft of the motor 9. The stirring rod 6 passes through the fixing plate 10 and the top of the mixing tank 1 and extends to the bottom of the mixing tank 1. Multiple stirring blades 5 are provided at equal intervals on the side wall of the stirring rod 6 inside the mixing tank 1. A control mechanism is provided inside the water tank 3, and a screening mechanism is provided inside the discharge pipe 12.

[0022] The control mechanism includes a movable plate 7 located at the bottom of the water tank 3. The movable plate 7 fits snugly against the inner bottom of the water tank 3 to prevent water from flowing into the leak 8 through the gap between the movable plate 7 and the water tank 3. The movable plate 7 has an opening with the same diameter as the leak 8. When the cam 17 pushes the movable plate 7 to its innermost position, the opening is perfectly aligned with the leak 8. One end of the movable plate 7 penetrates the side wall of the water tank 3. A sealing ring is provided at the penetration point between the movable plate 7 and the water tank 3 to prevent water from leaking out of the water tank 3. The end of the movable plate 7 located inside the water tank 3 is elastically connected to the inner wall of the water tank 3 by a spring. The cam 17 cooperates with the spring, causing the movable plate 7 to reciprocate, and water will flow intermittently into the mixing tank 1. The stirring rod 6 is fixedly connected to the cam 17 on the side wall outside the mixing tank 1. The movable 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 feed pipe 12. The screen 13 is made of flexible material. A first bevel gear is fixedly connected to the side wall of the stirring rod 6 outside the mixing tank 1. A vertical plate 16 is fixedly connected to the lower wall of the fixing plate 10. A rotating shaft 14 is provided through the side wall of the vertical plate 16. One end of the rotating shaft 14 passes through the side wall of the feed pipe 12 and extends into the feed pipe 12. A rotating rod 15 is fixedly connected to the end of the rotating shaft 14 inside the feed pipe 12. When the rotating rod 15 rotates, it continuously beats the screen 13, and the raw material is screened on the screen 13 and falls to the ground faster. A second bevel gear is fixedly connected to the end of the rotating shaft 14 away from the rotating rod 15. The first bevel gear meshes with the second bevel gear.

[0024] In this invention, raw materials and water are added to the material bin 11 and water tank 3 respectively. Then, the motor 9 is started. The output shaft of the motor 9 drives the stirring rod 6 to rotate. The rotation of the stirring rod 6 drives the stirring blade 5 to rotate, stirring the raw materials in the mixing tank 1. The first bevel gear on the stirring rod 6 drives the second bevel gear to rotate, thereby 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 raw materials into the mixing tank 1. Large particles of raw materials are screened on the screen 13. The rotation of the rotating rod 15 will also accelerate the falling of raw materials from the material bin 11 into the feed pipe 12.

[0025] When the stirring rod 6 rotates, the cam 17 intermittently pushes the moving plate 7 into the water tank 3, so that the opening on the moving plate 7 is aligned with the drain 8, and water will flow down. When the cam 17 stops pressing the moving plate 7, the spring will push the moving plate 7 back to its initial position, and the water will stop flowing in. In this way, the intermittent addition of water during stirring will ensure that the raw materials and water are fully mixed, avoiding the difficulty of stirring caused by uneven water absorption of the raw materials, and speeding up the stirring rate and quality.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
