Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent production, in particular to a mixing device for concrete water reducing agent production with an internal cleaning structure. Background Technique

[0002] Concrete water reducing agent is a surfactant. When added to concrete, it can reduce the water consumption under the condition of keeping the slump (fluidity) unchanged, or improve the fluidity when the water consumption remains unchanged. During its production process, various raw materials need to be put into a mixing tank and then stirred and mixed.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN201811066937.3 discloses a water reducing agent mixing and configuring device, which includes a bracket. Above the bracket, there is an outer shell. Horizontally arranged on the left side of the outer shell is a water inlet pipe, and horizontally arranged on the right side of the outer shell is a water outlet pipe. Vertically arranged inside the outer shell is a mixing tank. The mixing tank and the outer shell share a bottom plate. Vertically arranged inside the outer shell is a spiral heater, and the spiral heater is located outside the mixing tank. A tank cover is installed on the mixing tank. Vertically arranged on the tank cover is a solution inlet pipe, and the solution inlet pipe is connected and communicated with the tank cover. Vertically arranged on the tank cover is a material inlet pipe, and the material inlet pipe is connected and communicated with the tank cover. Vertically penetrating through the tank cover is a connecting pipe, and vertically arranged on the connecting pipe is a bearing box. Inside the bearing box is a rotating shaft; the upper end of the rotating shaft is installed in the rotating shaft through a bearing, and its lower end is arranged inside the mixing tank. At the lower end of the rotating shaft, there is a mixing blade connected.

[0004] Combined with the above materials, it can be seen that in the prior art, generally, the purpose of mixing water reducing agent is achieved by stirring. However, in the actual use process, the mixed water reducing agent needs to be discharged from the mixing tank for storage or enter the next process. When discharging, the water reducing agent in the mixing tank cannot be completely discharged. Without cleaning, it will affect the production quality of the next time. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mixing device for concrete water reducing agent production with an internal cleaning structure, so as to solve the problem of inconvenient cleaning of the interior of the device proposed in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A mixing device for the production of concrete water reducing agent with an internal cleaning structure, including a mixing tank in a cylindrical structure. A control panel is fixedly installed on the outer surface of the front side of the mixing tank. A first feed pipe and a second feed pipe are fixedly installed on the upper surface of the mixing tank, and a discharge pipe is fixedly installed on the lower surface of the mixing tank. A horizontally arranged support ring is installed at the upper end inside the mixing tank, and a plurality of flushing nozzles arranged at equal intervals are installed on the lower surface of the support ring. A water tank is fixedly installed on the outer surface of the left side of the mixing tank, and the water tank is interconnected with the support ring through a first connecting pipe.

[0007] Preferably, a pressure pump for conveying clear water is installed outside the first connecting pipe, and a fixing frame is fixedly installed on the upper surface of the support ring, and the fixing frame is fixedly installed with the inner wall of the mixing tank.

[0008] Preferably, the support ring is arranged in a hollow structure, and the support ring is interconnected with the flushing nozzles through a second connecting pipe.

[0009] Preferably, the flushing nozzle is rotatably connected to the support ring, a torsion spring is arranged at the position of the rotating shaft of the flushing nozzle, and a second magnetic block is fixedly installed on the outer surface of the flushing nozzle.

[0010] Preferably, a diffusion plate is fixedly installed on the upper surface of the fixing frame, and the diffusion plate is integrally arranged in a conical structure.

[0011] Preferably, a central rotating shaft is rotatably installed at the middle position inside the mixing tank, and the central rotating shaft is driven to rotate by a driving motor fixedly installed on the upper surface of the mixing tank.

[0012] Preferably, a stirring rod is fixedly installed outside the lower end of the central rotating shaft, a horizontally arranged connecting rod is fixedly installed outside the upper end of the central rotating shaft, and a first magnetic block is fixedly installed at the top end of the connecting rod. The first magnetic block and the second magnetic block are magnetically repellent to each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: The mixing device for the production of concrete water reducing agent with an internal cleaning structure adopts a novel structural design, and the specific content is as follows: 1. The raw materials for producing the water reducing agent are injected into the mixing tank through the first feed pipe and the second feed pipe for mixing. After mixing, they are discharged from the discharge pipe. Then, the clear water in the water tank is conveyed to the support ring through the first connecting pipe by the pressure pump and finally sprayed out from the flushing nozzles to achieve the purpose of flushing and cleaning the inside of the mixing tank. Furthermore, a diffusion plate is arranged above the fixing frame. When adding raw materials through the first feed pipe and the second feed pipe, the raw materials are more evenly dispersed under the blocking effect of the diffusion plate, which is convenient for subsequent mixing operations.

[0014] 2. During the mixing process, start the drive motor to drive the central shaft to rotate, so that the central shaft drives the stirring rod to rotate, achieving the stirring of the water reducing agent and accelerating the mixing speed. Furthermore, during flushing, the drive motor continues to drive the central shaft to rotate, so that the central shaft drives the connecting rod to rotate, and the connecting rod is used to drive the first magnetic block to move. When the first magnetic block moves to the position corresponding to the second magnetic block, the magnetic repulsive force is used to push the flushing nozzle to rotate, and then under the action of the torsion spring, the flushing nozzle resets, so that the flushing nozzle rotates reciprocally, expanding the overall flushing range.
