Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Refer to Figures 1-5 , a cooling device for water reducing agent, including a stirring tank 1, a feed pipe 13 and a discharge pipe 15 are arranged on the stirring tank 1, a bottom plate 2 is arranged below the stirring tank 1, a bracket 21 is arranged on the bottom plate 2, a temperature control box 11 and a temperature control probe 12 are arranged on the stirring tank 1, a shaking motor 3 and a bearing 22 are arranged on the bracket 21, a connecting shaft 14 is arranged on the bearing 22, a first stirring group 4 and a second stirring group 5 are arranged on the stirring tank 1, the first stirring group 4 and the second stirring group 5 are both composed of a stirring motor 41, a main shaft 42 and a stirring blade 43, an embedded groove 16 is arranged on the stirring tank 1, a heat conducting layer 161 and a heat conducting seat 6 are arranged in the embedded groove 16, a heat conducting fin 7 is arranged on the heat conducting seat 6, a cooling perforation 71 and a cooling cover 8 are arranged on the heat conducting fin 7, a cooling fan 82 is arranged in the cooling cover 8, the bearing 22 is a ball bearing, achieving the effect of stable rotation of the connecting shaft 14 in the bearing 22.

[0027] Manual valves are preset on the feed pipe 13 and the discharge pipe 15 to avoid material leakage.

[0028] Specifically, a motor shaft 31 is arranged on the shaking motor 3, the motor shaft 31 passes through the bracket 21 and is fixedly arranged with the stirring tank 1, the connecting shaft 14 is fixedly arranged with the outer wall of the stirring tank 1, an angle controller (prior art) is preset on the shaking motor 3, and the motor shaft 31 can rotate back and forth at a preset reciprocating rotation angle value, so as to realize the reciprocating rotation and shaking of the stirring tank 1 at a preset angle value.

[0029] Furthermore, the temperature control box 11, the temperature control probe 12 and the cooling fan 82 are electrically connected, a PLC is preset in the temperature control box 11, a temperature value can be preset on the temperature control box 11, and this temperature value is the temperature suitable for the stirring and mixing reaction of the water reducing agent raw material. The temperature control probe 12 is prior art.

[0030] Furthermore, the heat-conducting fins 7 are arranged on the outer side wall of the heat-conducting base 6. One set consists of the heat-conducting fins 7 and the heat-conducting base 6, and there are two sets symmetrically arranged on the left and right. There are twenty-two heat-conducting fins 7 arranged vertically. The heat-conducting fins 7 are made of aluminum alloy, which has excellent heat conductivity, wear resistance and durability.

[0031] More specifically, the cooling perforations 71 penetrate the heat-conducting fins 7 vertically. The interior of the cooling cover 8 is a hollow cavity and is connected to the cooling perforations 71. The cooling fan 82 is an axial-flow fan, which is durable at high speeds and can quickly blow away the heat accumulated in the heat-conducting fins 7 from bottom to top and dissipate it.

[0032] A bottom dust-proof net 81 and an upper dust-proof net 83 are provided inside the cooling cover 8. The filters of the bottom dust-proof net 81 and the upper dust-proof net 83 are non-woven fabrics, which can prevent external dust particles from entering the cooling fan 82.

[0033] Generally speaking, the heat-conducting base 6 is fixedly embedded in the embedded groove 16 and is in extrusion contact with the heat-conducting layer 161. The heat-conducting layer 161 is made of heat-conducting silica gel, which has excellent heat-conducting performance. Combining the metal material of the stirring tank 1 and the red copper material of the heat-conducting base 6, the heat can be quickly transferred to each heat-conducting fin 7 and dissipated, improving the cooling effect.

[0035] Working mode: Put a certain amount of water reducer raw materials into the mixing tank 1 through the feeding pipe 13, and then start the first mixing group 4, the second mixing group 5, the temperature control box 11, the temperature control probe 12, and the shaking motor 3. The mixing blades 43 on the first mixing group 4 and the second mixing group 5 will shake and mix the water reducer raw materials. At the same time, the temperature control probe 12 will monitor the temperature in the mixing tank 1 in real time and transmit the monitored temperature value signal to the control box 11 in real time. When shaking and mixing, the water reducer raw materials will generate heat by themselves. If the heat is higher than the appropriate temperature value preset on the temperature control box 11, the PLC in the temperature control box 11 will control the start of the cooling fan 82. The heat in the mixing tank 1 will be conducted to each heat conducting fin 7 through the heat conducting layer 161 and the heat conducting seat 6 and accumulate. At the same time, the started cooling fan 82 will quickly blow away the heat accumulated between each heat conducting fin 7 from bottom to top through the cooling perforations 71 for cooling. At the same time, the shaking motor 3 can also shake the water reducer raw materials in the mixing tank 1, which can further increase the effective contact area between the heat and the heat conducting layer 161, realize symmetric heat conduction cooling blowing while shaking the mixing tank 1, and conduct symmetric comprehensive mixing at the same time, improve the rapid heat conduction cooling of the generated heat, and thus ensure the final quality of the water reducer finished product.

[0036] In addition, the started shaking motor 3 will drive the mixing tank 1 to rotate left and right reciprocally at a certain angle value through the motor shaft 31. At the same time, the water reducer raw materials will pass through each mixing port 44 on the high-speed rotating mixing blade, realizing the symmetric stirring and shaking mixing effect of the water reducer raw materials, and further improving the mixing degree of the water reducer raw materials.
