Description

A mortar uniform mixing device for mortar production Technical Field

[0001] This utility model belongs to the field of mortar production technology, specifically referring to a mortar uniform mixing device for mortar production. Background Technology

[0002] Mortar is a binding material used in bricklaying in construction. It is made by mixing sand and binders such as cement, lime paste, and clay with water in a certain proportion. Mortar needs to be mixed during the production process. There are generally two existing technologies: the first is manual mixing, which has low input costs but low mixing efficiency; the second is machine mixing, which uses mixing blades to mix the mortar.

[0003] In the mortar production process, the uniformity of mixing directly affects the product's strength, durability, and workability. From the addition of raw materials to the completion of mixing, factors affecting uniformity include raw material characteristics, equipment design, and process parameters.

[0004] In the mortar production process, materials that are prone to agglomeration, such as fibers, silica fume, and fly ash, tend to clump together. These clumps are difficult to break up by the mixing blades, resulting in excessively high local concentrations. Furthermore, they require higher shear forces or longer periods of time to disperse, increasing energy consumption. Summary of the Invention

[0005] The technical problem this invention aims to solve is that in the mortar production process, the addition of easily agglomerated materials affects the uniformity of mixing, and there is a lack of auxiliary equipment to optimize their dispersion.

[0006] The technical solution adopted by this utility model is as follows:

[0007] This utility model proposes a mortar uniform mixing device for mortar production, including a mixing drum body, a top seat above the mixing drum body, a motor passing through the top seat, a mixing rod fixedly connected to the output shaft of the motor, a plurality of mixing blades fixedly connected to the mixing rod, and a pneumatic conveying unit, the pneumatic conveying unit including a feed cylinder connected to the mixing drum body on the top seat, an L-shaped conveying pipe connected to the upper part of the feed cylinder, and an air compressor connected to the front end of the L-shaped conveying pipe to provide power for the pneumatic conveying of raw materials.

[0008] Furthermore, a feeding square tube extends through the upper part of the L-shaped conveying pipe, and a feeding hopper is provided on the upper part of the feeding square tube.

[0009] Furthermore, a movable groove is provided on the side wall of the feed cylinder, and a sealing baffle is movably inserted into the movable groove.

[0010] Furthermore, a U-shaped mounting frame is fixedly connected to the L-shaped conveying pipe, and an electric push rod passes through the U-shaped mounting frame. The output end of the electric push rod is fixedly connected to one side of the sealing baffle.

[0011] Furthermore, an equipment bracket is fixedly connected to the outer wall of the mixing drum body, and a support frame is fixedly connected to both sides of the lower part of the top seat on the upper part of the equipment bracket.

[0012] Furthermore, the top seat is provided with an agglomeration treatment cylinder located on the other side of the motor and connected to the mixing cylinder body. A roller is rotatably provided on the inner wall of the agglomeration treatment cylinder, and a dispersing toothed rod is fixedly connected to the outer wall of the roller.

[0013] Furthermore, a second motor is inserted through the outer wall of the roller, and the output shaft of the second motor is fixedly connected to the roller.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] 1. By using pneumatic conveying, compressed air is used to blow powdery or fibrous materials into the mixing equipment, so that they are dispersed in the airflow and then mixed. The impact of the airflow can initially break up the agglomerates and reduce the subsequent mixing pressure.

[0016] 2. For damp materials that are inconvenient to convey pneumatically, pretreatment by breaking up clumps can improve the dispersion effect. Attached Figure Description

[0023] Example 1:

[0024] As shown in Figures 1, 2, and 3, this utility model proposes a mortar uniform mixing device for mortar production, comprising a mixing drum body 1, a top seat 11 above the mixing drum body 1, a motor passing through the top seat 11, a stirring rod 13 fixedly connected to the output shaft of the motor 12 inside the mixing drum body 1, and several stirring blades 14 fixedly connected to the stirring rod 13. It also includes a pneumatic conveying unit, which includes a feed cylinder 2 connected to the mixing drum body 1 and located on the top seat 11. An L-shaped conveying pipe 21 is connected to the upper part of the feed cylinder 2, and an air compressor 22 is connected to the front end of the L-shaped conveying pipe 21 to provide power for the pneumatic conveying of raw materials. Powdered or fibrous materials are blown from the L-shaped conveying pipe 21 and the feed cylinder 2 into the mixing drum body 1 by compressed air, causing them to disperse in the airflow before mixing. The airflow impact can initially break up agglomerates, reducing the subsequent mixing pressure.

[0025] As shown in Figures 1 and 4, the upper part of the L-shaped conveying pipe 21 is penetrated by a feeding square cylinder 23. The upper part of the feeding square cylinder 23 is provided with a feeding hopper 24, which can be put into the feeding hopper 24 and enter the L-shaped conveying pipe 21 through the feeding square cylinder 23. A movable groove 25 is opened on the side wall of the feeding square cylinder 23. A sealing baffle 26 is movably inserted into the movable groove 25. After the material is fed into the L-shaped conveying pipe 21, the sealing baffle 26 is inserted into the movable groove 25 to seal the feeding square cylinder 23, and then the air compressor 22 is controlled to work.

[0026] A U-shaped mounting frame 3 is fixedly connected to the L-shaped conveying pipe 21. An electric push rod 31 passes through the U-shaped mounting frame 3. The output end of the electric push rod 31 is fixedly connected to one side of the sealing baffle 26. By controlling the operation of the electric push rod 31, the extension and retraction adjustment of the output end can be realized, and the sealing baffle 26 can be pulled to switch between the sealing and feeding states inside the feeding square cylinder 23.

[0027] The mixing drum body 1 is fixedly connected to the outer wall of the equipment support 4. The upper part of the equipment support 4 is provided with support frames 41 fixed to both sides of the lower part of the top seat 11, which plays a role in stabilizing the equipment.

[0028] Example 2:

[0029] As shown in Figures 2 and 5, the top seat 11 is provided with a clumping treatment cylinder 5 located on the other side of the motor 12 and connected to the mixing cylinder body 1. A roller 51 is rotatably provided on the inner wall of the clumping treatment cylinder 5, and a dispersing toothed rod 52 is fixedly connected to the outer wall of the roller 51. A motor passes through the outer wall of the roller 51, and the output shaft of the second motor 53 is fixedly connected to the roller 51.

[0030] In practical use, the user puts the wet material that is inconvenient to be pneumatically conveyed into the agglomeration treatment cylinder 5, and drives the roller 51 to rotate by the motor 53. In conjunction with the dispersing toothed rod 52, the material is broken up and agglomerated, realizing the pretreatment function and improving the dispersion effect.

[0031] The above is the entire usage process of a mortar uniform mixing device for mortar production.
