Description

Technical Field

[0001] The utility model relates to the technical field of concrete engineering, in particular to a concrete additive reaction kettle. Background Art

[0002] Concrete additives are materials used to improve the performance of concrete and are widely used in concrete engineering. When preparing concrete additives, the raw materials of the additives need to be placed in a reactor for reaction. The reactor is equipped with an agitator to accelerate the reaction process. After the reaction, some of the raw materials will adhere to the inner wall of the reactor. In order to prevent corrosion, the reactor needs to be cleaned.

[0003] Traditional cleaning methods include chemical cleaning and mechanical cleaning. The mechanical cleaning method is to manually use a high-pressure water gun to flush the inner wall of the reactor. The reactor cover needs to be opened each time for flushing. Since the reactor cover is bulky and inconvenient to open, each cleaning process is complicated and time-consuming, and the flushing efficiency is low. Utility Model Content

[0007] Compared with the prior art, the principles and beneficial effects of the utility model are as follows:

[0008] In this solution, when the reactor is working, the adjustment component is used to adjust the position of the inner tube so that the spray hole corresponds to the side wall of the inner tube. At this time, the side wall of the inner tube can cover the spray hole to prevent the reactants from entering the inner tube and the stirring shaft. After the reaction is completed, the position of the inner tube is adjusted so that the water outlet hole coincides with the spray hole. At this time, the water outlet hole and the spray hole form a water flow channel, and then water is injected into the inner tube. The water in the inner tube is sprayed out from the channel to spray the inner wall of the reactor. When using this solution to clean the inner wall of the reactor, there is no need to open the bulky kettle cover, which can greatly reduce the work intensity of the staff. During cleaning, multiple spray holes on the stirring shaft can be sprayed at the same time, and the cleaning speed is fast and the efficiency is high.

In addition to injecting water, the water injection pipe arranged in this scheme can also serve as a handle when adjusting the position of the inner tube, and the staff can hold the water injection pipe to rotate the inner tube.

[0010] As a preferred embodiment of the utility model, a limiting structure for limiting the sliding of the water injection pipe is arranged above the strip hole, and the limiting structure includes a mounting ring fixed to the outside of the stirring shaft, and a limiting rod is provided on the mounting ring corresponding to the position in the middle of the strip hole for vertical sliding, and the limiting rod is placed against the side wall of the water injection pipe. In this solution, after the water injection pipe slides to the end of the strip hole, the limiting rod slides downward, and the limiting rod is placed against the side wall of the water injection pipe to lock the water injection pipe and prevent the water injection pipe from sliding freely.

After the adjustment is completed, the slider is released, and the slider and the limit rod slide down along the slide rail, and the limit rod is placed against the side wall of the water injection pipe.

[0021] The stirring shaft 4 is hollow inside, and an inner tube 6 is inserted into the stirring shaft 4 and fits with the inner wall of the stirring shaft 4. Both ends of the inner tube 6 are closed, and a plurality of water outlet holes 61 are evenly opened on the side wall of the inner tube 6. The plurality of water outlet holes 61 are evenly distributed in the circumferential and axial directions of the inner tube 6. A plurality of spray holes 41 are opened on the side wall of the stirring shaft 4 to match the plurality of water outlet holes 61. An adjustment structure is provided between the stirring shaft 4 and the inner tube 6. The position of the inner tube 6 is adjusted by the adjustment structure. When the water outlet hole 61 coincides with the spray hole 41, the water outlet hole 61 and the spray hole 41 form a water flow channel that is connected to the inside of the kettle body 1, and the water in the inner tube 6 can be sprayed out from the channel to spray the inner wall of the reactor.

[0022] The adjusting structure is located in the space formed by the top plate 33, the bottom plate 31 and a plurality of supporting rods 32. The adjusting structure includes a strip hole 42 opened on the side wall of the stirring shaft 4. The strip hole 42 is arranged horizontally. A water injection pipe 62 is installed on the side wall of the inner tube 6. The water injection pipe 62 is inserted into the strip hole 42 and can slide along the strip hole 42. A limiting structure is arranged above the strip hole 42. The limiting structure is used to limit the sliding of the water injection pipe 62. The limiting structure includes a mounting ring 7 fixed to the outside of the stirring shaft 4. A vertical slide rail 71 is installed on the mounting ring 7 at a position corresponding to the middle of the strip hole 42. The slide rail 71 is matched with a slider 72.

[0023] Specific implementation process:

[0024] When the reactor is working, hold the water injection pipe 62 to rotate the inner tube 6. When the water injection pipe 62 slides to one end of the strip hole 42, the spray hole 41 corresponds to the side wall of the inner tube 6. At this time, the side wall of the inner tube 6 can block the spray hole 41 to prevent the reactants from entering the inner tube 6 and the stirring shaft 4. After the reaction is completed, hold the water injection pipe 62 to rotate the inner tube 6 in the opposite direction. When the water injection pipe 62 slides to the other end of the strip hole 42, the water outlet hole 61 coincides with the spray hole 41. At this time, the water outlet hole 61 and the spray hole 41 form a water flow channel, and then the water pipe is connected to the water injection pipe 62 to inject water into the inner tube 6. The water in the inner tube 6 is sprayed out from the channel to spray the inner wall of the reactor. Using this solution to clean the inner wall of the reactor, there is no need to open the bulky kettle cover 2, which can greatly reduce the work intensity of the staff. During cleaning, multiple spray holes 41 on the stirring shaft 4 can be sprayed at the same time, and the cleaning speed is fast and the efficiency is high.

[0025] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
