Description

Technical Field

[0001] The utility model belongs to the technical field of polycarboxylic acid water reducing agent preparation, and specifically relates to a polycarboxylic acid high-performance water reducing agent preparation device. Background Art

[0002] Polycarboxylic acid water reducer has an artificially designed molecular structure, with a high proportion of effective ingredients and a concentrated molecular weight range. Compared with other water reducers, polycarboxylic acid water reducer not only has a high water reduction rate and a long-lasting slump, but also has a smaller dosage.

[0003] Chinese patent CN218890419U discloses a device for manufacturing polycarboxylic acid high-performance water reducing agent, including a processing tank, the upper surface of which is connected to a feed pipe, the upper surface of which is provided with a mixing mechanism, the left side of which is connected to a liquid inlet pipe, and the right side of which is provided with a drying mechanism.

[0004] The above patent heats the inside of the treatment tank through a drying mechanism to prevent crystallization in the treatment tank during the preparation of the water reducer (on the one hand, crystallization changes the performance of the water reducer, and on the other hand, it adheres to the inside of the treatment tank and the mixing mechanism, which is inconvenient to clean). However, when the drying mechanism heats the inside of the treatment tank through the air outlet pipe, it can only have a good heating effect on the water reducer near the air outlet pipe, and cannot heat the inside of the treatment tank evenly, which is not effective in preventing crystallization in the preparation process of the water reducer. Therefore, a technical measure is proposed to solve the problem that when the drying mechanism heats the inside of the treatment tank through the air outlet pipe, it can only have a good heating effect on the water reducer near the air outlet pipe, and cannot heat the inside of the treatment tank evenly, which is not effective in preventing crystallization in the preparation process of the water reducer.

The lower end of the electric telescopic rod 13 is installed on the upper surface of the fixing ring 7, and a plurality of support rods 11 are provided at the lower end of the fixing ring 7. When the electric telescopic rod 13 is started, the electric telescopic rod 13 is started to drive the ear plate 8 to move upward, and the ear plate 8 moves upward to drive the tank cover 4 to move upward. When the tank cover 4 moves upward, it drives the stirring component 2 to move upward. When the tank cover 4 is a distance away from the tank body 1, raw materials are injected into the tank body 1, and then the electric telescopic rod 13 is used to drive the tank cover 4 back to the initial position.

[0026] Reference Figure 1 , Figure 4 As shown, the stirring assembly 2 includes a motor 201, which is fixedly mounted on the upper surface of the tank cover 4. The motor 201 is connected to a vertical rod 205, which passes through the tank cover 4. A plurality of stirring plates 202 are installed on the side of the vertical rod 205, and the stirring plates 202 are adapted to the internal size of the tank body 1. A connecting rod 204 is connected to the center position of the side of the vertical rod 205, and the connecting rod 204 is connected to a rotating plate 203. A scraper 206 is installed on the side of the rotating plate 203 away from the connecting rod 204, and the scraper 206 contacts the inner wall of the tank body 1. The motor 201 is started, and the motor 201 starts to drive the vertical rod 205 to rotate. The rotation of the vertical rod 205 drives the stirring plate 202 to rotate. The stirring plate 202 rotates to stir and mix the raw materials. When the vertical rod 205 rotates, it also drives the connecting rod 204 to rotate. The rotation of the connecting rod 204 drives the rotating plate 203 to rotate. The rotation of the rotating plate 203 drives the scraper 206 to scrape the inside of the tank body 1 to prevent the mixed material from adhering to the upper part of the inside of the tank body 1.

When the heating rod 305 heats the water box 306, the water is heated by the temperature. The meter 304 observes the temperature of the water inside the water box 306. When the appropriate temperature is reached, the heating rod 305 maintains the water temperature stable and does not continue to heat the water upward. Then the water pump 302 is started. The water pump 302 starts to pump the water flow inside the water box 306 to the second connecting pipe 308. Then the water flows into the cavity inside the tank body 1 through the water inlet pipe 5, and the raw materials inside the tank body 1 are evenly heated, which effectively prevents crystallization during the preparation process of the water reducer and facilitates the cleaning of the inside of the tank body 1. At the same time, the water flow inside the cavity 12 and the water flow in the water box 306 are circulated through the water pump 302 to ensure that the water temperature inside the cavity 12 does not change. Through the setting of the water level line 307, when the water level is low, the pipe cover is opened to inject water into the water box 306. After the stirring is completed, the valve 9 is opened, and the stirred water reducer is discharged from the tank body 1 through the discharge pipe 10.

[0028] Working principle: When the water reducing agent is actually prepared, the electric telescopic rod 13 is started, and the electric telescopic rod 13 is started to drive the ear plate 8 to move upward, and the ear plate 8 moves upward to drive the tank cover 4 to move upward, and the tank cover 4 moves upward to drive the stirring assembly 2 to move upward, and when the tank cover 4 is a certain distance from the tank body 1, the raw material is injected into the tank body 1, and then the electric telescopic rod 13 is used to drive the tank cover 4 back to the initial position;

[0029] Then, the stirring assembly 2 is started, specifically, the motor 201 is started, the motor 201 starts to drive the vertical rod 205 to rotate, the vertical rod 205 rotates to drive the stirring plate 202 to rotate, the stirring plate 202 rotates to stir and mix the raw materials, and the vertical rod 205 rotates and drives the connecting rod 204 to rotate, the connecting rod 204 rotates to drive the rotating plate 203 to rotate, and the rotating plate 203 rotates to drive the scraper 206 to scrape the inside of the tank body 1 to prevent the mixed material from adhering to the upper part of the inside of the tank body 1;

[0030] When adding raw materials, start the heating rod 305 to heat the water in the water box 306. When the heating rod 305 heats the water box 306, observe the temperature of the water in the water box 306 through the thermometer 304. When the appropriate temperature is reached, the heating rod 305 keeps the water temperature stable and does not continue to heat the water upward. Then start the water pump 302. The water pump 302 starts to pump the water flow in the water box 306 to the second connecting pipe 308. Then the water flows into the cavity inside the tank body 1 through the water inlet pipe 5, and the raw materials in the tank body 1 are evenly heated, effectively preventing crystallization during the preparation process of the water reducer, and facilitating the cleaning of the tank body 1. At the same time, the water flow in the cavity 12 and the water flow in the water box 306 are circulated through the water pump 302 to ensure that the water temperature in the cavity 12 does not change. Through the setting of the water level line 307, when the water level is low, open the pipe cover to fill the water box 306 with water. After stirring is completed, open the valve 9, and the stirred water reducer is discharged from the tank body 1 through the discharge pipe 10.
