Description

TECHNICAL FIELD

[0001] The utility model relates to material processing device field, especially a kind of mixed online shotcreting device. BACKGROUND

[0002] The mixing machine is a mechanical device that uses mechanical force and gravity to mix two or more materials evenly. During the mixing process, the contact surface area of the materials can be increased to promote chemical reactions and accelerate physical changes. However, when mixing materials with slurry, clumping and uneven mixing often occur, resulting in low quality of the mixed materials and poor performance. SUMMARY

[0003] The utility model aims at overcoming the shortcomings and deficiencies of the prior art and provides a mixed online shotcreting device.

[0004] A mixed online shotcreting device includes a mixing hopper, a mixing machine, and a shotcreting mechanism. The mixing hopper has an inlet at its upper end, and the shotcreting mechanism is installed at the inlet. The mixing machine is connected to the mixing hopper and drives it to move up and down in the axial direction. When the mixing hopper is at the highest position, the shotcreting mechanism sprays slurry. The slurry is atomized and evenly sprayed on the surface of the materials during the mixing process. Then, the materials and slurry are mixed. During the mixing process, the shotcreting mechanism is repeatedly started and stopped to atomize the slurry. The fine slurry is evenly attached to the surface of the materials, and then the materials are mixed again. This eliminates the phenomenon of material clumping and clumping caused by slurry dripping, greatly improving the uniformity of the mixed materials.

[0005] Preferably, the shotcreting mechanism includes a shotcreting trolley for transporting slurry, a peristaltic pump installed on the mixing hopper, a needle, a spray gun, a respirator, and a pneumatic butterfly valve. When the mixing hopper is at the highest position, the spray gun is opened to transport the atomized slurry and mix it with the materials. When the mixing hopper moves away from the highest position, the peristaltic pump, spray gun, air path, and pneumatic butterfly valve are closed in sequence. The slurry is atomized and evenly sprayed on the surface of the materials during the mixing process. Then, the materials and slurry are mixed. During the mixing process, the shotcreting mechanism is repeatedly started and stopped to atomize the slurry. The fine slurry is evenly attached to the surface of the materials, and then the materials are mixed again. This eliminates the phenomenon of material clumping and clumping caused by slurry dripping, greatly improving the uniformity of the mixed materials.

[0006] Further, the air path for slurry atomization is provided between the spray gun and the peristaltic pump, the through needle is used for controlling the opening and closing of the spray gun, and the peristaltic pump is used for conveying liquid to the spray gun. The peristaltic pump can accurately adjust the liquid flow, ensure that the slurry is supplied on demand, and avoid uneven mixing or waste caused by excessive or insufficient slurry flow. The combination of air path atomization and peristaltic pump can adjust the spray angle, particle size and flow, and adapt to different types of slurry and material mixing requirements. By optimizing the slurry spraying method, the slurry is more evenly wrapped on the surface of the material, ensuring the stability and consistency of the mixing process, thereby improving the product quality.

[0007] Further, a conduit is provided on the slurry spraying trolley, and the conduit is connected with the peristaltic pump, and the peristaltic pump is connected with the spray gun. By connecting the peristaltic pump through the conduit, the slurry spraying trolley can continuously and stably supply slurry during movement, ensuring consistent slurry spraying effect.

[0008] Further, a rotator is provided on the slurry spraying trolley, and the rotator is connected with the conduit. The rotating spray gun can adjust different rotating speeds and spraying modes to adapt to the mixing requirements of different fluid viscosities and particle sizes, and improve the application range of the equipment.

[0009] Further, the conduit is a flexible conduit. The flexible conduit has good bending adaptability and can freely swing with the movement of the trolley, avoiding the problem that the travel of the slurry spraying trolley is limited due to the limitation of the conduit.

[0010] Further, the pneumatic butterfly valve is connected with the peristaltic pump, and the pneumatic butterfly valve is arranged at the lower end of the peristaltic pump. The peristaltic pump is responsible for conveying slurry, but its flow adjustment range is limited, while the pneumatic butterfly valve can accurately control the opening and closing of the slurry spraying and the flow size, ensuring that the slurry spraying is more uniform and stable.

[0011] Further, the slurry spraying mechanism further comprises a breather, the breather is connected with the pneumatic butterfly valve, and the on-off state of the breather corresponds to the pneumatic butterfly valve one by one. The breather can supply air in time when the butterfly valve is closed, prevent slurry backflow and deposition, reduce the risk of pipeline blockage, and improve the stability of the system. The breather can adjust the pipeline pressure, so that the peristaltic pump is in a stable working state, reduces the loss of the hose, and improves the durability of the equipment.

[0012] The effect of the utility model is that the slurry is atomized, sprayed uniformly on the surface of the material during mixing, and then mixed with the material, the slurry is atomized repeatedly during the mixing process, the fine slurry is uniformly attached to the surface of the material, and then mixed, so that the phenomenon of material agglomeration and caking caused by slurry dripping is eliminated, and the uniformity of material mixing is greatly improved.
