Description

Technical Field

[0001] This utility model relates to the field of polycarboxylate superplasticizer condensation technology, specifically a rapid condensation mechanism for the production of high-performance polycarboxylate superplasticizer. Background Technology

[0002] Polycarboxylate superplasticizer is a high-performance water-reducing agent and a cement dispersant used in cement concrete. It is widely used in highways, bridges, dams, tunnels, high-rise buildings, and other projects. When used, it can reduce the amount of water used in concrete construction, lower the water-cement ratio, increase concrete strength, shorten the concrete curing period, ensure the progress of project construction, and give concrete long-term durability and corrosion resistance. Moreover, this product is green and environmentally friendly, non-flammable, and non-explosive, and can be safely transported by train and truck. When storing polycarboxylate superplasticizer, it is necessary to perform condensation storage. Therefore, a rapid condensation mechanism for the production of high-performance polycarboxylate superplasticizer is provided.

[0003] For example, a condensation device for preparing polycarboxylate-based high-performance water-reducing agents, as described in announcement number "CN217568712U," uses an air-cooled agitator to increase internal airflow and help lower the temperature between the outer and inner condensation chambers, preventing the internal coolant temperature from rising too high and reducing condensation efficiency. However, in the condensation of polycarboxylate water-reducing agents described above, the water in the tank heats up during use due to warmer weather, thus reducing the achievable cooling effect. Therefore, it is only suitable for use in normal or cold weather, resulting in significant limitations. Furthermore, the condensation of the polycarboxylate water-reducing agent by cold water through the cooling ring pipes and cooling system is slow and dispersed, leading to poor condensation efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the water inside the tank will heat up as the weather gets hotter, which will reduce the cooling effect and limit its application to normal or cold weather. At the same time, the condensation of the polycarboxylate superplasticizer by the cold water through the cooling ring pipe and cooling system is slow and dispersed, resulting in poor condensation effect. Therefore, a rapid condensation mechanism for the production of high-performance polycarboxylate superplasticizer is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid condensation mechanism for the production of polycarboxylate superplasticizer is designed, comprising a base and a first tank. The upper end of the outer wall of the base is fixedly connected to the first tank. A second tank is fixedly connected to the inner wall of the first tank via a bracket. A polycarboxylate superplasticizer condensation and stirring structure is provided on the upper end of the outer wall of the first tank. A polycarboxylate superplasticizer condensation structure is provided on the left side of the upper end of the outer wall of the base. The upper right end of the second tank is fixedly connected to a liquid inlet. The outer wall of the liquid inlet is fixedly connected to the first tank.

[0007] Preferably, the polycarboxylate superplasticizer condensation structure includes a third tank. A condenser is fixedly connected to the upper left side of the outer wall of the third tank via a bracket. The condenser is fixedly connected to the upper end of the first pipe. A one-way valve is installed at the lower end of the first pipe. The outer wall of the first pipe is fixedly connected to the third tank. The lower right end of the third tank is fixedly connected to the second pipe. The right end of the second pipe is fixedly connected to the first tank.

[0008] Preferably, the upper right side of the third tank is provided with a water inlet, the lower end of the third tank is fixedly connected to the water outlet, and the outer wall of the water outlet is fixedly connected to the base.

[0009] Preferably, the lower right end of the second tank is fixedly connected to the liquid outlet, and the outer wall of the liquid outlet is fixedly connected to the first tank.

[0010] Preferably, the polycarboxylate superplasticizer condensation and stirring structure includes a motor, a vertical pipe fixedly connected to the end of the motor output shaft, the upper end of the vertical pipe being rotatably connected to the first tank and the second tank via a sealed bearing, the middle part of the vertical pipe being fixedly connected to a sphere, the upper end of the vertical pipe being rotatably connected to a third pipe via a sealed bearing, the outer wall of the third pipe being fixedly connected to the first tank, a water pump being installed in the middle of the third pipe, the outer wall of the water pump being fixedly connected to the third tank, and the left end of the third pipe being fixedly connected to the third tank.

[0011] Preferably, the outer wall of the motor is fixedly connected to the first tank via a bracket, and the lower end of the vertical pipe is rotatably connected to the second tank via a sealed bearing.

[0012] This utility model proposes a rapid condensation mechanism for the production of polycarboxylate superplasticizers. The advantages are as follows: Through the coordination of the polycarboxylate superplasticizer condensation and stirring structure and the polycarboxylate superplasticizer condensation structure, the condenser starts, spraying cold air into the first pipe and the one-way valve (the one-way valve prevents water from flowing from the third tank to the left end of the first pipe), and spraying it into the third tank through multiple through-holes at its end to cool the water. The water pump starts, drawing cold water through the third pipe to the vertical pipe and the sphere. Further cold water flows from the lower end of the vertical pipe into the first tank, thereby condensing the polycarboxylate superplasticizer in the second tank from the inside out. The first motor starts, driving the vertical pipe in the second tank... The first tank, second tank, and third pipeline rotate via sealed bearings. The rotation of the vertical pipe drives multiple blades on its outer wall to rotate synchronously, stirring the polycarboxylate superplasticizer. A condenser cools the water, making it suitable for condensing the polycarboxylate superplasticizer in hot weather, effectively reducing the condensation limitations of the polycarboxylate superplasticizer. A water pump draws cold water into the vertical pipe and the sphere, and then flows out of the vertical pipe into the first tank. The cold water condenses the polycarboxylate superplasticizer from the inside out. The motor drives the vertical pipe and its outer blades to rotate, stirring the polycarboxylate superplasticizer to make the condensation more uniform, effectively increasing the condensation effect of the polycarboxylate superplasticizer, thereby achieving high performance.

The outer wall of the first pipe 202 is fixedly connected to the third tank 204. The lower right end of the third tank 204 is fixedly connected to the second pipe 205.

[0027] Working principle:

[0028] Polycarboxylate superplasticizer rapid condensation operation:

[0029] When rapid condensation is required, open the valve in the middle of the inlet 5 to input an appropriate amount of polycarboxylate superplasticizer into the second tank 7 and close the valve. Then, input an appropriate amount of water from the upper right opening of the third tank 204. Then, connect the external power supply to the condenser 201. The condenser 201 starts to convert the gas or vapor into liquid and transfers the heat in it to a long tube (usually coiled into a solenoid) in a fast manner, allowing the heat to dissipate into the surrounding air. To improve the efficiency of the condenser, heat sinks with excellent heat conduction performance are often added to the pipe to increase the heat dissipation area and accelerate heat dissipation. The air convection is accelerated by the fan to carry away the heat for cooling.

[0030] The cold air is further sprayed into the first pipe 202 and the one-way valve 203 (the one-way valve 203 can block the water inside the third tank 204 from flowing to the left end of the first pipe 202), and sprayed into the third tank 204 from multiple through holes at its end to cool the water. At the same time, the gas can be discharged from the water inlet on the right side of the upper end of the third tank 204. Then the external power supply of the water pump 104 is connected, and the water pump 104 starts to pump the cold water into the vertical pipe 102 and the ball 103 through the third pipe 104. The cold water flows out from the lower end of the vertical pipe 102 into the first tank 4, thereby condensing the polycarboxylate superplasticizer in the second tank 7 from the inside to the outside.

[0031] Simultaneously, the external power supply of the first motor 101 is connected. The first motor 101 starts and drives the vertical pipe 102 to rotate through the sealed bearings in the first tank 4, the second tank 7, and the third pipe 104. The rotation of the vertical pipe 102 drives multiple blades on its outer wall to rotate synchronously to stir the polycarboxylate superplasticizer, making the polycarboxylate superplasticizer condense more evenly, thereby improving the condensation effect and performance. When it is necessary to cool the water in the first tank 4 again, the valve in the middle of the second pipe 205 is opened, so that the water in the first tank 4 flows to the third tank 204 for subsequent cooling. This allows for water circulation and cooling. When it is necessary to discharge the polycarboxylate superplasticizer, the valve in the middle of the outlet 6 is opened, and the polycarboxylate superplasticizer can be discharged from the outlet 6. When it is necessary to discharge water, the valve in the middle of the outlet 8 is opened to discharge the water. In cold weather, it is not necessary to start the condenser 201; the water can be cooled by the air temperature of the outer shell.
