Technical Field

[0001] The utility model relates to the technical field of concrete mixing equipment, in particular to a fast and efficient concrete mixing system. Background Art

[0002] In places such as concrete mixing plants, the recycling of sewage and fine sand has always been a difficult problem. Traditional mixing systems have problems such as uneven mixing, high energy consumption, and low fine sand recovery rate. In order to solve the above technical problems, technicians in this field have made the following efforts. For example, the Chinese patent authorization announcement number is CN215311702U, which discloses an automatic sewage mixing system and a sewage treatment system, which can fully mix the sewage generated by the concrete cleaning equipment and concrete to prevent precipitation and achieve short-term storage and treatment. However, the above scheme still exists: the bottom sewage cannot be regularly or effectively transported to the cyclone sedimentation tank, resulting in the sewage concentration cannot be effectively reduced; high-concentration sewage may increase the difficulty and cost of subsequent treatment, which is not conducive to environmental protection and resource recovery. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a fast and efficient concrete mixing system, and solve the problems of bottom particle deposition and low fine sand recovery efficiency after sewage is stored in the mixing tank on site of the engineering station.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A fast and efficient concrete mixing system includes a control system, and a fast mixing system, an automatic water discharge system and a cyclone separation system connected to the control system, wherein:

[0006] The rapid stirring system is arranged inside the stirring tank, and includes a stirring motor, a stirring shaft and a pressure flow blade; the edge of the pressure flow blade is bent downward and installed at a certain angle to the stirring shaft; the stirring motor drives the stirring shaft to rotate, thereby driving the pressure flow blade to stir rapidly;

[0007] The automatic water discharge system is arranged at the bottom of the mixing tank, and includes a water discharge pipe, a pneumatic butterfly valve and an air compressor; one end of the water discharge pipe is connected to the bottom of the mixing tank, and the other end is connected to the conical pool through the pneumatic butterfly valve. The air compressor provides an air source for the pneumatic butterfly valve. The control system controls the operation of the air compressor, thereby controlling the action of the pneumatic butterfly valve, and regularly transports the high-concentration sewage at the bottom of the mixing tank to the conical pool;

[0008] The cyclone separation system includes a conical tank, a slurry pump and a cyclone sedimentation tank; one end of the slurry pump is connected to the conical tank, and the other end is connected to the cyclone sedimentation tank. The high-concentration sewage in the conical tank is washed by the cyclone sedimentation tank, and the sand aggregate is transported to the silo, and the low-concentration sewage is returned to the mixing tank through the pipeline;

[0009] In addition, the stirring tank comprises a tank body and a guide plate, and the guide plate is arranged on the tank body at an inclined angle.

[0010] This technical solution reduces the sewage concentration in the mixing tank and improves the efficiency of fine sand recovery on site by combining an efficient and fast mixing device with a cyclone sedimentation tank. This technical solution achieves automation, efficiency and intelligence of the mixing process by constructing a fast and efficient concrete mixing system including a control system, a fast mixing system, an automatic water discharge system and a cyclone separation system; wherein a fast mixing system is set inside the mixing tank, an automatic water discharge system is set at the bottom, and a cyclone separation system is set on one side, and through the coordinated work of pressure flow blades, water discharge pipes, pneumatic butterfly valves, air compressors, slurry pumps and other components, efficient mixing of materials, automatic discharge of sewage and separation of sand and aggregates are achieved. Specifically, the edge of the pressure flow blade is set to bend downward to increase the coverage area and stirring effect of the stirring, make the stirring more uniform and efficient, and effectively prevent the accumulation of materials at the bottom of the stirring tank; through the high-speed rotation of the stirring motor, the pressure flow blade quickly stirs the material, so that the material reaches a uniform mixing state in a short time; the control system detects the particle deposition at the bottom of the stirring tank based on the signal fed back by the sensor, and controls the operation of the air compressor and the opening and closing of the pneumatic butterfly valve to achieve regular release of high-concentration sewage, avoiding the tediousness and errors of manual operation; the slurry pump pumps the high-concentration sewage in the conical pool to the cyclone sedimentation tank. After cyclone washing, the sand aggregate is transported to the silo through a pipeline, while the low-concentration sewage is returned to the stirring tank through another pipeline, realizing the recycling of resources; in addition, the guide plate is set at an inclined angle, which helps to guide the flow of materials in the stirring tank, improve the stirring efficiency, and facilitate the uniform distribution of sewage in the stirring tank.

[0011] In addition, the fast and efficient concrete mixing system proposed in the utility model also has the following additional technical features:

[0012] According to an embodiment of the utility model, the pressure flow blades are blades made of corrosion-resistant material, and four blades are installed on the stirring shaft in a group at a certain angle to form a stirring structure with a pressure flow effect.

[0013] This technical solution achieves efficient and corrosion-resistant stirring effects by using corrosion-resistant materials and reasonable blade structures to meet the stirring needs of different materials and environments. Specifically, each blade rotates under the drive of the stirring shaft and cooperates with other blades to act on the sewage together; the inclination angle and installation position of the blade directly act on a wide range of fluid materials to produce a concentrated high-speed extrusion flow effect, thereby improving the stirring efficiency; the corrosion-resistant material blades effectively prevent the blades from being damaged by chemical corrosion, thereby extending the service life of the stirring system and reducing maintenance costs.

[0014] According to an embodiment of the utility model, the guide plate is a plate made of corrosion-resistant material, and adjacent guide plates are regularly arranged to form a stirring structure for adjusting the flow direction and speed of sewage.

[0015] This technical solution uses corrosion-resistant materials and a reasonable guide plate structure to control the flow state of sewage, optimize the flow environment in the mixing tank, and improve the mixing efficiency and effect. Specifically, by reasonably setting the shape, angle and spacing of the guide plate, the flow state of sewage can be accurately controlled, so that it can produce eddies, vortices and other flow forms that are conducive to mixing; when sewage flows in the mixing tank, it will form certain eddies or vortices under the guidance of the guide plate. The eddies or vortices can drive the materials in the sewage to rotate and tumble, thereby achieving more uniform mixing; the eddies or vortices can also increase the contact area and contact time between the sewage and the pressure flow blades, improving the mixing efficiency and effect; the guide plate made of corrosion-resistant material ensures that the guide plate is not easily damaged by corrosion during long-term use, thereby extending the service life of the tank and reducing maintenance costs.

[0016] According to an embodiment of the utility model, a concentration detection device is arranged above the stirring tank, and the concentration detection device is connected to the control system.

[0017] This technical solution realizes real-time monitoring and feedback of the material concentration in the mixing tank by setting a concentration detection device above the mixing tank and connecting it to the control system, so that the control system can adjust the mixing, draining or separation operations according to the concentration information, thereby improving the intelligence level and operation accuracy of the system. Specifically, when the liquid concentration in the mixing tank reaches a preset threshold or range, the control system accelerates the mixing, opens the drain pipe, etc.; if the sewage concentration in the mixing tank exceeds the preset safety range, the control system triggers the alarm mechanism to notify the operator or automatically take emergency measures.

[0018] According to an embodiment of the utility model, the control system is a control cabinet, and the control cabinet is respectively connected to the stirring motor, the pneumatic butterfly valve, the air compressor, the slurry pump, and the concentration detection device.

[0019] The control cabinet of this technical solution detects the concentration of sewage in the tank through a concentration detection device. When it exceeds a certain threshold, it means that the sewage concentration is too high. The pneumatic butterfly valve is opened by the air compressor to release high-concentration sewage from the drain pipe at the bottom of the tank; the high-concentration sewage in the cone pool is sent to the cyclone sedimentation tank for cyclone washing through the slurry pump, the sand aggregate is sent to the silo, and the low-concentration sewage is sent back to the tank.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] (1) By adding corrosion-resistant guide plates in the tank, the direction of liquid rotation is effectively changed to form a vortex, the flow direction and speed of sewage are adjusted, and the stirring effect is improved;

[0022] (2) The stirring motor adopts a helical gear reducer, and the pressure flow blade is made of corrosion-resistant and wear-resistant material. Its edge is set at an angle downward to form a pressure flow, which has a good stirring effect and effectively prevents mud from silting at the bottom and around the stirring tank;

[0023] (3) A sewage circulation pipeline is set at the bottom of the mixing tank. Through the control of a pneumatic butterfly valve, the high-concentration sewage at the bottom can be regularly transported to the cyclone sedimentation tank. The cyclone sedimentation tank can cyclone wash the sewage and recover the fine sand particles in the sewage. The low-concentration sewage after cyclone washing returns to the mixing tank, effectively reducing the slurry concentration in the tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In addition, the fast and efficient concrete mixing system proposed in the utility model also has the following additional technical features:

[0035] According to an embodiment of the present invention, the pressure flow blades 9 are blades made of corrosion-resistant material, and four blades are installed on the stirring shaft 8 at a certain angle in a group to form a stirring structure with a pressure flow effect.

[0036] This technical solution achieves efficient and corrosion-resistant stirring effect by adopting corrosion-resistant materials and reasonable blade structure to meet the stirring requirements of different materials and environments.
