Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent processing, and more specifically to a synthesis device of a polycarboxylic acid water reducing agent. Background Art

[0002] Water reducer is a commonly used admixture in concrete mixes. Its main function is to reduce the water demand in concrete mixtures to improve the working performance and strength of concrete. According to different chemical compositions and action mechanisms, water reducers can be divided into ordinary water reducers, high-efficiency water reducers and super-high-efficiency water reducers (such as polycarboxylic acid water reducers).

[0003] A synthesis device is required for the processing of water reducers. The synthesis production of water reducers usually involves a series of chemical reactions, and some volatile substances will be generated. These substances will escape in the form of gas to form waste gas. At the same time, the uniformity of stirring will also affect the temperature distribution of the reaction system. Uneven stirring will cause local overheating and accelerate the evaporation of volatile substances, thereby increasing the generation of waste gas. In addition, the existing synthesis device does not treat the waste gas generated and directly discharges it into the air. The waste gas contains some harmful gases or particulate matter. Releasing it into the atmosphere will not only cause air pollution, but also affect the health of surrounding workers.

[0004] In view of this, we propose a synthesis device for polycarboxylic acid water reducer. Utility Model Content

At the top, when the staff processes the synthetic water reducing agent through the mixing barrel 1, the suction fan 205 is operated at the same time. The operation of the suction fan 205 can generate suction, and the suction pipe makes the connected treatment box 201 also generate suction. After the suction is generated inside the treatment box 201, the exhaust gas generated inside the connected mixing barrel 1 will be sucked into the treatment box 201 for filtering. After the exhaust gas is sucked into the treatment, the exhaust gas will first be filtered by the filter element 202 to filter out large particles of debris in the exhaust gas, and then pass through the filter plate 203, and under the action of the filter plate 203, the fine harmful particles will be filtered, and then through the adsorption of multiple active carbon adsorption bags 204, different water vapor and harmful substances can be adsorbed, and then the treated exhaust gas is filtered and discharged through the suction pipe of the suction fan 205 and the suction fan 205, thereby reducing the emission of harmful substances, reducing pollution to the atmospheric environment, and helping to protect the ecological environment and human health.

[0028] Specifically, the stirring mechanism includes a sleeve shaft 301, a rotating shaft 302, a stirring rod 303, a stirring blade 304, a bevel gear 305, a rotating motor 306 and an output wheel 307. The sleeve shaft 301 is connected to the inside of the top cover of the mixing barrel 1 through a bearing, and the bottom end of the sleeve shaft 301 penetrates into the inside of the mixing barrel 1. The rotating shaft 302 is connected to the inside of the sleeve shaft 301 through a bearing, one end of the rotating shaft 302 penetrates into the inside of the mixing barrel 1, and the other end of the rotating shaft 302 penetrates into the top of the sleeve shaft 301. The stirring rod 303 is fixedly connected to the surface of the rotating shaft 302, the stirring blade 304 is fixedly connected to the surface of the sleeve shaft 301, and the bevel gear 305 is sleeved on the top of the surface of the rotating shaft 302. There are two bevel gears 305, which are sleeved on the surface of the rotating shaft 302 relatively up and down. The bottom bevel gear 305 is fixedly connected to the top of the sleeve shaft 301. The rotating motor 306 is fixedly connected to the top of the sleeve shaft 301. It is fixedly installed on the top of the mixing barrel 1, and the output wheel 307 is fixedly connected to the rotating shaft 302 of the rotating motor 306. The output wheel 307 is meshed and connected to one side of the two bevel gears 305. When processing the water reducer, the rotating motor 306 is operated at the same time. The operation of the rotating motor 306 will drive the output wheel 307 to rotate. The rotation of the output wheel 307 will drive the two meshing bevel gears 305 to rotate clockwise and counterclockwise at the same time. When the two bevel gears 305 rotate clockwise and counterclockwise respectively, the rotating shaft 302 and the sleeve shaft 301 will be driven to rotate clockwise and counterclockwise respectively, and at the same time, the stirring rod 303 and the stirring blade 304 can be driven to rotate clockwise and counterclockwise respectively. In this way, the raw materials on the inner wall of the mixing barrel 1 can be stirred and mixed in two directions at the same time, the material distribution in the mixing barrel 1 can be balanced, the mixing speed of the materials can be accelerated, and the uniformity of the mixing can be improved.

[0029] Furthermore, an auxiliary part 4 is provided on the top of the surface of the rotating shaft 302, and the auxiliary part 4 is fixedly installed on the top of the mixing barrel 1. When the rotating shaft 302 rotates, the rotating shaft 302 can be limited and stabilized with the auxiliary support of the auxiliary part 4 to prevent the rotating shaft 302 from shaking due to lack of limit during rotation.

[0030] It is worth mentioning that a door panel 5 is hingedly connected to one side of the treatment box 201, and a handle is fixedly connected to one side of the door panel 5. The handle is circular in shape. After the exhaust gas treatment mechanism has been working for a period of time, the staff can open the door panel 5 through the handle and easily replace the adsorption bag 204 on the filter plate 203, so that the adsorption bag 204 can reach a better working state, thereby improving its convenience.

[0031] In addition, a hole 6 is opened on one side of the stirring blade 304, and the hole 6 extends to the other side of the stirring blade 304. There are several holes 6, which are evenly distributed on the surface of the stirring blade 304. When the stirring blade 304 rotates, the resistance of the stirring blade 304 and the raw materials during mixing can be reduced under the action of multiple holes 6, thereby improving the stirring efficiency of the stirring mechanism.

[0032] It must be said that the bottom of the inner wall of the mixing barrel 1 is inclined relative to the vertical direction of the discharge pipe 101, so that the processed material can flow smoothly into the discharge pipe 101 for discharge under the inclined bottom wall, preventing the material from accumulating inside the mixing barrel 1.

[0033] Working principle: when the staff processes the synthetic water reducing agent through the mixing barrel 1, the suction fan 205 is operated at the same time. The operation of the suction fan 205 can generate suction, and the suction pipe makes the connected treatment box 201 also generate suction. After the suction is generated inside the treatment box 201, the waste gas generated inside the connected mixing barrel 1 will be sucked into the treatment box 201 for filtering and treatment. After the waste gas is sucked into the treatment, the waste gas will first be filtered by the filter element 202 to filter out large particles of debris in the waste gas, and then pass through the filter plate 203, and under the action of the filter plate 203, the fine harmful particles will be filtered, and then through the adsorption of multiple active carbon adsorption bags 204, different water vapor and harmful substances can be adsorbed, and then the treated waste gas will be filtered and discharged through the suction pipe of the suction fan 205 and the suction fan 205, thereby reducing the emission of harmful substances, reducing pollution to the atmospheric environment, and helping to protect the ecological environment and human health.
