Description

Technical Field

[0001] The utility model relates to the technical field of polycarboxylic acid water reducer preparation, in particular to a polycarboxylic acid water reducer compounding production feeding and regulating device. Background Art

[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Most of them are anionic surfactants. According to the water reducing and enhancing capabilities, they are mainly divided into ordinary water reducers, high-efficiency water reducers and high-performance water reducers. Among them, polycarboxylate water reducer is a high-performance water reducer and a cement dispersant in cement concrete. It is widely used in projects such as roads, bridges, dams, tunnels, and high-rise buildings. It has the advantages of being green and environmentally friendly, non-flammable, non-explosive, and can be safely transported by train and car. In the production process of polycarboxylate water reducer, a variety of raw materials and additives are usually required. Through the production feeding adjustment device, a variety of raw materials and additives can be added during the compounding of polycarboxylate water reducer to ensure the accuracy of the raw material ratio after compounding and the quality of the polycarboxylate water reducer after production.

[0003] However, the production feeding adjustment device in the prior art has the following problems:

[0004] 1. When feeding, the raw material mass inside the metering tank is weighed and then put into the compounding tank to control the accuracy of feeding. However, the raw materials and additives of polycarboxylate water reducer are mostly liquids. During the weighing process, some raw materials adhere to the pipe wall or the inner wall of the tank, resulting in a certain difference in the mass of the raw materials entering the compounding tank and the raw materials weighed out, reducing the accuracy of the ratio;

[0005] 2. After the compounding is completed, the inside of the compounding tank needs to be cleaned before the next compounding can be carried out. Currently, most of the cleaning is done manually, which is troublesome and has low cleaning efficiency. In addition, the raw materials remaining on the inner wall of the discharge pipe at the bottom of the compounding tank may come into contact with the air and solidify on the inner wall of the discharge pipe, increasing the difficulty of cleaning.

[0035] Working principle: When compounding the polycarboxylate water-reducing agent, first place the raw materials in the storage barrel 10, and then close the feed port 11. At this time, the electric telescopic rod 2 can be started, and the electric telescopic rod 2 can drive the piston 5 to move upward in the batching barrel 6, so that the space at the bottom of the piston 5 in the batching barrel 6 increases and the pressure decreases. Since the pressure inside the storage barrel 10 is relatively high, the raw materials inside the storage barrel 10 will flow from the connecting pipe 9 into the compounding barrel. According to calculations, after a certain amount of solution flows in, the electric valve can be started. At this time, due to the air circulation inside the conduit 7, the pressure difference between the batching barrel 6 and the storage barrel 10 is destroyed, causing the raw materials inside the batching barrel 6 to flow from the inside of the conduit 7 into the inside of the compounding tank 12. At the same time, the electric telescopic rod 2 drives the piston 5 to move downward inside the batching barrel 6, so that the piston 5 blocks the pipe opening of the connecting pipe 9, thereby preventing the raw materials inside the storage barrel 10 from flowing out. When the raw materials inside the batching barrel 6 are exhausted, the electric valve 8 can be closed, and the above operation is repeated. After repeated operations, the raw materials are discharged according to the pressure. The proportion is added into the compounding tank 12, and then the motor 13 is started to stir. When the stirring is completed, the electric valve 28 can be started to make the prepared polycarboxylate water reducer flow out from the discharge pipe 27, and then clean water is added to the inside of the compounding tank 12, and the motor 13 is started again. The motor 13 drives the rotating rod 14 to rotate. When the rotating rod 14 rotates, it will drive the external brush 20 to scrub the inner wall of the compounding tank 12. When the brush 20 contacts the inner wall of the compounding tank 12, the brush 20 will be due to the curvature of the inner wall. The movable plate 18 is driven to squeeze the spring 17, so that the brush 20 can adapt to the curved inner wall, thereby ensuring that the brush 20 is always in contact with the inner wall and improving the cleaning effect. At the same time, the scraper 1 22 will scrape the bottom of the inner wall of the compounding tank 12, and the scraper 2 24 will scrape the inner wall of the discharge pipe 27, so as to remove the solidified impurities of the polycarboxylic acid water reducer remaining on the inner wall, reduce the trouble of manual cleaning, and improve the cleaning efficiency. After cleaning, the electric valve 2 28 can be started to discharge the sewage from the discharge pipe 27.
