Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent production, in particular to a high-efficiency water reducing agent synthesis device. Background Art

[0002] Water reducers are concrete admixtures that reduce mixing water usage while maintaining a relatively constant concrete slump. Most are anionic surfactants, including lignin sulfonates and naphthalene sulfonate formaldehyde polymers. The synthesis of water reducers is exothermic, and if the heat released can't be transferred quickly, the reactor temperature will overheat. High reaction temperatures lead to faster reaction speeds and can cause localized polymerization.

[0003] Publication number: CN221287835U, discloses "a water-reducing agent synthesis reactor, comprising a reactor body, an agitator, a spray device, and a cooling device; the reactor body is a hollow structure with a cover provided on the top, the cover having a feed port; the bottom of the reactor body has a discharge port; the agitator motor is provided on the cover, the upper end of the agitator rod is connected to the motor shaft of the motor, and the lower end of the agitator rod extends from the cover into the reactor body and is connected to the agitator blade assembly; the spray device is installed below the cover and is connected to an external water source via a pipe; the cooling device includes a cooling coil."

[0004] There are still certain disadvantages when using it. The temperature is cooled from the inside of the reactor through the coil. However, during stirring, the area where the impeller rotates is large, and the coil is only distributed near the outside of the solution. The solution near the stirring rod is not easy to cool down under the action of the coil, which easily leads to a higher temperature near the inside of the solution, resulting in side reactions or thermal degradation of the polymer, affecting product performance. Moreover, if there is a large temperature difference between the low-temperature water and the solution, too rapid cooling will also lead to reduced stability during the reaction, affecting the performance of the water reducer in concrete, and it is not convenient to control the temperature of the cooling water.

The heat generated by the solution is utilized to heat the coolant, reducing the temperature difference between the coolant and the solution, avoiding excessive cooling that leads to reduced stability during the reaction, and improving the performance of the water reducer.

[0030] 3. The No. 2 motor runs, driving the baffle to move, adjusting the area of ​​the baffle blocking the air collecting pipe and the exhaust pipe, controlling the flow of air into the air collecting pipe, making it easier to control the heat used to heat the coolant inside the water tank. When the coolant does not need to be heated, the heat carried by the air can be completely discharged from the exhaust pipe, making it easier to control the initial temperature of the coolant.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-5 In an embodiment of the present invention, a high-efficiency synthesis device for a water reducer includes a reaction bin 1, a stirring assembly 2 is arranged inside the reaction bin 1, the stirring assembly 2 includes a hollow stirring rod 201 rotatably connected to the inside of the reaction bin 1, a water inlet pipe 202 is fixedly installed at the upper end of the hollow stirring rod 201, a water outlet pipe 203 is fixedly installed at the lower end of the hollow stirring rod 201, one end of the water inlet pipe 202 and the water outlet pipe 203 are fixedly connected at equal angles with a plurality of water branch pipes 204 that pass through the hollow stirring rod 201, and a plurality of vertical pipes 205 are fixedly connected between two water branch pipes 204 in the same direction at equal distances, the heat dissipation assembly 3 is fixedly installed on the upper end surface of the reaction bin 1, and the adjustment assembly 4 is fixedly installed below the heat dissipation assembly 3.

[0039] Specifically, the stirring component 2 rotates and, while stirring the solution, extracts the heat generated by the solution reaction from multiple locations. The heat dissipation component 3 can dissipate the extracted heat to the outside, and can also preheat the incoming coolant to increase its initial temperature to avoid reaction instability caused by a rapid drop in temperature.

[0040] Example 1

[0041] like Figure 2 As shown, in this embodiment, a No. 1 motor 208 is fixedly installed on the upper end surface of the reaction chamber 1 through a bracket, and a No. 1 gear 209 is fixedly installed at the output end of the No. 1 motor 208 and the upper end of the outer surface of the hollow stirring rod 201, and the two No. 1 gears 209 are meshed and connected for transmission, and a plurality of heat conducting plates 206 are fixedly installed at equal intervals on the outer surface of the vertical tube 205.

[0042] In this embodiment, the No. 1 motor 208 is in operation, and the No. 1 gear 209 is used to drive the hollow stirring rod 201 to rotate, thereby driving the water distribution pipe 204 and the vertical pipe 205 to rotate. When the coolant flows through the water distribution pipe 204 and the vertical pipe 205, the heat conducting plate 206 increases the heat exchange area, and cools the solution from multiple areas. Thus, by allowing the cooling water to conduct the temperature of the solution during the reaction from multiple positions, the solution near the hollow stirring rod 201 is also easy to cool, so that the temperature inside and outside the solution can be quickly controlled, thereby avoiding the high temperature of the solution near the inside, which may cause side reactions or thermal degradation of the polymer.

[0043] like Figure 2-4 As shown, in this embodiment, a connecting pipe No. 1 is fixedly installed at one end of the No. 1 heat dissipation coil 303, a water pump 207 is fixedly installed on the lower end surface of the reaction chamber 1, one end of the connecting pipe No. 1 is fixedly connected to the water pump 207, and a connecting pipe No. 2 is fixedly connected to the outer surface of the water chamber 302; the other ends of the water outlet pipe 203 and the water inlet pipe 202 are fixedly connected with a rotary joint, the water outlet pipe 203 is fixedly connected to the water pump 207 through the rotary joint, and the water inlet pipe 202 is fixedly connected to the No. 2 connecting pipe 306 through the rotary joint.

[0044] During specific implementation, the rotary joint allows the water inlet pipe 202 and the water outlet pipe 203 to rotate without affecting the circulation of the coolant, and the water pump 207 allows the coolant to circulate.

[0045] like Figure 2 and Figure 3 As shown, in this embodiment, the heat dissipation component 3 includes: a heat dissipation bin 301 is fixedly installed on the upper end surface of the reaction bin 1, a water bin 302 is fixedly installed on the upper end surface of the reaction bin 1 and is located on one side of the heat dissipation bin 301, a heat dissipation coil No. 1 303 is fixedly installed on the inner surface of the heat dissipation bin 301, and both ends pass through the heat dissipation bin 301, a heat dissipation coil No. 2 304 is fixedly installed on the inner surface of the water bin 302, and both ends pass through the water bin 302; the other end of the heat dissipation coil No. 1 303 is fixedly connected to the water bin 302, and the other end of the heat dissipation coil No. 2 304 is fixedly installed with an air collecting pipe 308, the lower end of the heat dissipation bin 301 is fixedly installed with an air inlet pipe 307, and the connection port at the upper end of the heat dissipation bin 301 is externally connected to a fan.

[0046] During specific implementation, the water pump 207 runs, driving the coolant inside the water tank 302 to circulate, flowing through the No. 1 heat dissipation coil 303, the water distribution pipe 204 and the vertical pipe 205. When the coolant carries heat into the No. 1 heat dissipation coil 303, the fan outside the heat dissipation tank 301 runs, cooling it through air flow, so that the air carries heat and enters the No. 2 heat dissipation coil 304, heating the coolant entering the water tank 302, so that the coolant carries part of the heat when entering the vertical pipe 205, thereby utilizing the heat generated by the solution to heat the coolant, reduce the temperature difference between the coolant and the solution, avoid excessive cooling that leads to reduced stability during the reaction, and improve the performance of the water reducer. A temperature sensor is set inside the water tank 302 to monitor the temperature changes inside the water tank 302 in order to understand the initial temperature of the coolant.

[0047] Example 2

[0048] On the basis of the first embodiment, in order to make up for the problem that the heat entering the second heat dissipation coil 304 is difficult to control.

[0049] like Figure 5 As shown, in this embodiment, the adjustment component 4 includes: an adjustment chamber 401 fixedly installed between the air collecting pipe 308 and the air inlet pipe 307, an exhaust pipe 402 fixedly installed on one end surface of the adjustment chamber 401, a baffle 403 slidingly connected to the inside of the adjustment chamber 401, a rack 405 fixedly installed on one side surface of the baffle 403, a No. 2 motor 404 fixedly installed on the upper surface of the adjustment chamber 401, and the output end passes through the adjustment chamber 401, and a No. 2 gear 406 fixedly installed on the output end of the No. 2 motor 404, and meshingly connected with the rack 405 for transmission.

[0050] During specific implementation, the No. 2 motor 404 runs, driving the No. 2 gear 406 to run, and through the meshing transmission with the rack 405, the baffle 403 is pushed to move, and the area of ​​the baffle 403 blocking the air collecting pipe 308 and the exhaust pipe 402 is adjusted to control the flow of air into the air collecting pipe 308, so that the heat of the coolant heated in the water tank 302 is easy to control. When the coolant does not need to be heated, the heat carried by the air can be completely discharged from the exhaust pipe 402, which is convenient for controlling the initial temperature of the coolant.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
