Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent production technology, specifically a cooling device for water-reducing agents. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining a relatively constant slump. Most of them are anionic surfactants, such as lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. After being added to concrete mixes, they disperse cement particles, improve workability, reduce unit water consumption, and improve the fluidity of concrete mixes; or reduce unit cement consumption, thus saving cement. Water-reducing agents require cooling of materials during production to improve production efficiency.

[0003] Existing methods for cooling water-reducing agent synthesis reactions typically employ jacketed reactors, where the cooling medium circulates within the reactor jacket and exchanges heat with the reactants through the reactor wall. After the peak of the exothermic reaction, if the cooling water flow rate is not precisely controlled, continuous cooling may cause the reactor temperature to drop too quickly, deviating from the optimal reaction temperature range and affecting the polymerization reaction. Furthermore, the heat exchange area between the cooling water and the reactor is fixed, making it difficult to adjust the cooling efficiency by adjusting the heat exchange area between the reactor and the cooling water. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for water-reducing agents to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cooling device for a water-reducing agent, comprising: Reactor; Heat exchange chamber located outside the reactor: The cooling assembly is located inside the heat exchange chamber. The cooling assembly includes multiple heat-conducting pipes that are fixedly inserted through the heat exchange chamber at equal angles. A first heat-conducting plate that is fixedly connected to the reactor is fixedly installed on the outside of the heat-conducting pipes. A second heat-conducting plate is movably attached to the outside of the heat-conducting pipes. Two transmission components are located at both ends of the reactor.

[0006] Furthermore, the upper ends of multiple heat pipes are fixedly connected to water distribution pipes, and the lower ends of multiple heat pipes are fixedly connected to water collection pipes.

[0007] Furthermore, a rotating shaft is fixedly installed on one side of the No. 2 heat-conducting plate, which moves through the heat exchange chamber. An arc-shaped reinforcing plate that moves in contact with the heat-conducting pipe is fixedly installed at equal intervals on one side of the No. 2 heat-conducting plate.

[0008] Preferred: The transmission assembly includes: A retaining ring is installed on the outer surface of the reactor. Multiple extension plates are fixedly installed at equal angles on the outer surface of the fixing ring; Multiple rotating rods are rotatably connected to the inside of the extension plate at corresponding positions via bearings.

[0009] Preferred configuration: A U-shaped frame is fixedly installed on the upper surface of the extension plate, and multiple U-shaped frames are internally connected by toothed rings.

[0010] Preferably, a No. 1 gear is fixedly installed at the upper end of the rotating rod, and multiple No. 1 gears are meshed and connected to the gear ring for transmission. The two ends of the rotating shaft are fixedly connected to the rotating rod at the corresponding positions.

[0011] Preferably, a protective shell is fixedly installed on the outside of the heat exchange chamber, and a motor is fixedly installed on one side surface of the protective shell via a bracket. A second gear that meshes with the gear ring is fixedly installed at the output end of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The contact area between the heat pipe and the reactor is increased by the No. 1 heat-conducting plate. After heat exchange, the cooling water carrying heat flows out from one end of the water collection pipe and enters the chiller unit for cooling. The circulation is cyclical. The motor runs, causing the gear ring to rotate, which drives multiple No. 2 heat-conducting plates to rotate around the heat pipe at the corresponding position. Thus, the rotation of the No. 2 heat-conducting plates separates from and adheres to the reactor body, adjusting the heat exchange area between the heat pipe and the reactor body. When the cooling water flow rate is not accurately controlled, the cooling rate of the water-reducing agent is reduced by decreasing the heat exchange area, reducing the impact of continuous cooling on the polymerization reaction, and improving the control accuracy of the cooling temperature.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 In this embodiment of the present invention, a cooling device for a water-reducing agent includes a reaction vessel 1 and a heat exchange chamber 101 disposed outside the reaction vessel 1. A cooling component 2 is disposed inside the heat exchange chamber 101. The cooling component 2 includes a plurality of heat-conducting pipes 201 fixedly passing through the heat exchange chamber 101 at equal angles. A first heat-conducting plate 202 fixedly installed on the outside of the heat-conducting pipes 201 and fixedly connected to the reaction vessel 1, and a second heat-conducting plate 206 movably attached to the outside of the heat-conducting pipes 201. Two transmission components 3 are disposed at both ends of the reaction vessel 1.

[0017] Specifically, the polymerization reaction of the water-reducing agent takes place inside the reactor 1. The cooling component 2 is connected to an external chiller unit, which allows cooling water to flow through the heat pipe 201 to remove the heat generated by the polymerization reaction of the water-reducing agent. The transmission component 3 controls the second heat-conducting plate 206 to make it adhere to and move away from the outer wall of the reactor 1, thereby adjusting the heat exchange area.

[0018] Example 1 like Figure 2-5 As shown, in this embodiment, the upper ends of multiple heat pipes 201 are fixedly connected to water distribution pipes 203, and the lower ends of multiple heat pipes 201 are fixedly connected to water collection pipes 204; a rotating shaft 205 is fixedly installed on one side surface of the second heat-conducting plate 206, and the rotating shaft 205 movably passes through the heat exchange chamber 101; an arc-shaped reinforcing plate 207 that movably fits the heat pipes 201 is fixedly installed at equal intervals on one side surface of the second heat-conducting plate 206, and the arc-shaped reinforcing plate 207 increases the connection between the second heat-conducting plate 206 and the heat pipes 201, making it easier for the second heat-conducting plate 206 to rotate around the heat pipes 201.

[0019] In this embodiment, cooling water flows into multiple heat-conducting pipes 201 through the water distribution pipe 203. The first heat-conducting plate 202 increases the contact area with the reactor 1, improving the heat exchange rate. Then, the cooled water, carrying heat, flows out from one end of the water collection pipe 204 and enters the chiller unit for cooling. The water circulates. By rotating the shaft 205, the second heat-conducting plate 206 rotates, preventing it from contacting the reactor 1. This rotation of the second heat-conducting plate 206 separates it from and allows it to adhere to the reactor body, adjusting the heat exchange area between the heat-conducting pipes 201 and the reactor body. When the cooling water flow rate is not accurately controlled, reducing the heat exchange area decreases the cooling rate of the water-reducing agent, reducing the impact of continuous cooling on the polymerization reaction and improving the control accuracy of the cooling temperature.

[0020] like Figure 2 and Figure 3 As shown, in this embodiment, the transmission assembly 3 includes a fixed ring 301, multiple extension plates 302, and multiple rotating rods 305. The fixed ring 301 is disposed on the outer surface of the reactor 1. The multiple extension plates 302 are fixedly installed at equal angles on the outer surface of the fixed ring 301. The extension plates 302 support the rotating rods 305. The multiple rotating rods 305 are rotatably connected to the interior of the extension plates 302 at corresponding positions through bearings. A U-shaped frame 303 is fixedly installed on the upper surface of the extension plate 302. A gear ring 304 is rotatably connected inside the multiple U-shaped frames 303. A first gear 306 is fixedly installed on the upper end of the rotating rod 305, and the multiple first gears 306 are meshed and connected to the gear ring 304. The two ends of the rotating shaft 205 are fixedly connected to the rotating rods 305 at corresponding positions.

[0021] In practice, the two gear rings 304 rotate simultaneously, driving multiple first gears 306 to rotate. Through the rotating rod 305 and the heat pipe 201 being on the same axis, multiple rotating shafts 205 rotate, driving multiple second heat-conducting plates 206 to rotate around the heat pipe 201 at the corresponding position, making it easy to control multiple second heat-conducting plates 206 simultaneously.

[0022] Example 2 Based on Example 1, in order to solve the problem that manual control of the No. 2 heat conduction plate 206 is too cumbersome.

[0023] like Figure 2 and Figure 3 As shown, in this embodiment, a protective shell 309 is fixedly installed on the outside of the heat exchange chamber 101. The protective shell 309 protects the gear ring 304 to prevent dust from entering the meshing point of the first gear 306, the second gear 308, and the gear ring 304, ensuring normal transmission of the three. A motor 307 is fixedly installed on one side surface of the protective shell 309 through a bracket. The output end of the motor 307 is fixedly installed with the second gear 308 that meshes with the gear ring 304.

[0024] In practice, the motor 307 operates, driving the second gear 308 to operate. Through the meshing transmission between the second gear 308 and the gear ring 304, the gear ring 304 rotates, replacing the manual rotation of the gear ring 304, which facilitates the control of the second heat conduction plate 206.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
