Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of concrete processing equipment, and in particular relates to a mixing device for producing concrete retarder. Background Technology
[0002] The concrete retarder production mixing unit is a piece of equipment specifically designed for retarder production. It mainly consists of a frame, mixing tank, drive and control system. The mixing tank typically adopts a double-layer structure, with an inner corrosion-resistant layer and an outer insulation layer. The unit is equipped with precise feeding and discharging systems. During feeding, the proportions of each raw material can be accurately controlled, and the discharge is smooth and can filter impurities. The drive mechanism drives the mixing paddle to operate efficiently, ensuring thorough mixing of the raw materials. The control system can precisely adjust and monitor parameters such as mixing time.
[0003] In actual processing, existing concrete retarder mixing devices generally rely on screw conveyors and mixing blades to mix materials. The former drives the concrete retarder raw materials to move by screw conveying and turning, while the latter achieves mixing of raw materials and additives by rapidly rotating blades. However, during the turning and mixing process, the internal temperature of the material continues to rise due to the mutual friction and collision between particles and the heat generated by the operation of the equipment. After the temperature rises, the physical properties of the material, such as viscosity and fluidity, will change, which will affect the uniformity and efficiency of mixing and thus affect the mixing effect.
[0004] To address these issues, we provide a mixing apparatus for producing concrete retarder. Utility Model Content
[0005] The purpose of this invention is to provide a mixing device for producing concrete retarder. By using a combination of a temperature control component and a drive component, it solves the problem that the temperature rise during the mixing process of existing concrete retarder mixing devices will affect the mixing effect of the materials.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a mixing device for producing concrete retarder, comprising a mixing tank, a rotating rod movably connected inside the mixing tank, a conveying pipe installed inside the rotating rod, and mixing blades installed on the surface of the conveying pipe; a temperature control component is provided on one side of the mixing tank, the temperature control component including a temperature sensor installed inside the mixing tank, a water tank installed at the top of the mixing tank, and a cooler disposed through one side of the water tank; a drive component is provided on one side of the mixing tank, the drive component including a water delivery shell installed at the top of the mixing tank, a first gear installed on the surface of the rotating rod, and a second gear meshing with one side of the first gear.

[0015] The present invention has the following beneficial effects.
[0016] 1. This utility model achieves efficient mixing of materials by rotating the mixing blades driven by the rotating rod.

[0017] 2. This utility model uses a temperature sensor to monitor the material temperature in real time and transmits the data to the control system. In conjunction with the cooler, the water in the water tank is circulated and cooled.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0027] For a specific implementation example, please refer to Implementation Example 1. Figures 1-5This utility model is a mixing device for producing concrete retarder, including a mixing tank 1, a rotating rod 2 movably connected inside the mixing tank 1, a conveying pipe 3 installed inside the rotating rod 2, and mixing blades 4 installed on the surface of the conveying pipe 3; a temperature control component 5 is provided on one side of the mixing tank 1, the temperature control component 5 includes a temperature sensor 501 installed inside the mixing tank 1, a water tank 502 installed on the top of the mixing tank 1, and a cooler 503 that passes through one side of the water tank 502; a drive component 6 is provided on one side of the mixing tank 1, the drive component 6 includes a water delivery shell 601 installed on the top of the mixing tank 1, a first gear 602 installed on the surface of the rotating rod 2, and a second gear 603 meshing with one side of the first gear 602.
[0028] Specifically, the conveying pipe 3 is installed inside the rotating rod 2. When the rotating rod 2 rotates, it can drive the mixing blade 4 to rotate. There are three conveying pipes 3. The top and bottom of the three conveying pipes 3 are connected to the first circulation shell 7 and the second circulation shell 8, respectively. All three conveying pipes 3 are designed with bends to increase the circulation path of cooling water. When the material temperature changes, the physical characteristics (resistance) of the temperature sensing element of the temperature sensor 501 change accordingly. This change is converted into an electrical signal by the internal circuit of the sensor. The electrical signal is transmitted to the control system to monitor the mixing temperature in real time. The cooler 503 cools the water inside the water tank 502, mainly based on the principle of refrigeration cycle. The compressor in the refrigeration system compresses the refrigerant into a high-temperature and high-pressure gas, which enters the condenser to dissipate heat and liquefy. The liquid refrigerant enters the evaporator after being depressurized by the throttling device, where it absorbs the heat of the water in the water tank 502 and vaporizes, thus lowering the water temperature. This cycle achieves continuous cooling, which is a mature existing technology application.
[0029] For a specific embodiment two, please refer to Figures 1-5 Based on the first specific embodiment, the drive assembly 6 further includes a bracket 604 mounted on the top of the mixing tank 1, a drive motor 605 mounted on the bottom of the bracket 604, the output end of the drive motor 605 passing through the water delivery shell 601 and fixedly connected to the second gear 603, a first circulation shell 7 mounted on one side of the bracket 604, the surface of the rotating rod 2 being movably connected to the inner wall of the first circulation shell 7 via a first bearing, one end of the conveying pipe 3 communicating with the first circulation shell 7, a second circulation shell 8 mounted on the bottom of the mixing tank 1, and the surface of the rotating rod 2 being movably connected to the inner wall of the first circulation shell 7 via a first bearing. The two bearings are movably connected to the inner wall of the second circulation shell 8. The other end of the conveying pipe 3 is connected to the second circulation shell 8. A water conveying pipe 9 is connected between the first circulation shell 7 and the water conveying shell 601. A connecting pipe 10 is connected between the water conveying shell 601 and the water tank 502. A circulation pipe 11 is connected to one side of the second circulation shell 8. The other end of the circulation pipe 11 is connected to the water tank 502. A discharge pipe 12 is connected to the bottom of the mixing tank 1. A valve is sleeved on the surface of the discharge pipe 12. A feed pipe 13 is connected to one side of the mixing tank 1. A stabilizing seat 14 is installed on one side of the mixing tank 1.
[0030] Specifically, the first gear 602 and the second gear 603 mesh together to form a gear pump inside the water tank 601. When the gears rotate in a specific direction, the teeth gradually disengage, the inter-tooth volume increases, and a partial vacuum is formed. Water in the water tank 502 is drawn in under atmospheric pressure. As the gears continue to rotate, the inter-tooth volume decreases due to the gradual meshing of the teeth, which compresses the water and delivers it through the water pipe 9 and the connecting pipe 10, thus achieving a stable water flow.
[0031] The operation process of this embodiment is as follows: After the worker puts the raw materials and additives of the concrete retarder into the mixing tank 1 through the feed pipe 13, the drive motor 605 is started. The drive motor 605, together with the second gear 603, drives the first gear 602 to rotate. The first gear 602, together with the rotating rod 2, drives the conveying pipe 3 to rotate. The conveying pipe 3 drives the mixing blades 4 to rotate, stirring and mixing the raw materials and additives of the concrete retarder, thereby improving the mixing effect.
[0032] When the second gear 603 drives the first gear 602 to rotate relative to each other, the water inside the water supply shell 601 can be transported. The cooling water inside the water tank 502 is drawn into the second circulation shell 8 through the circulation pipe 11, and then enters the conveying pipe 3 after passing through the second circulation shell 8. When the cooling water is transported inside the conveying pipe 3, it can dissipate the temperature and cool the material. After the cooling water passes through the first circulation shell 7, enters the water supply pipe 9, the water supply shell 601, and the connecting pipe 10, it is discharged back into the water tank 502. The water flow is cooled again by the cooler 503. This can achieve simultaneous cooling while mixing the materials, avoiding the high temperature generated during mixing from affecting the materials.
