Description

Technical Field

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

[0002] Water-reducing agents are concrete admixtures that reduce the amount of mixing water while maintaining a relatively constant concrete slump. During the production of water-reducing agents, cooling devices are needed to control the reaction temperature, adjust the material viscosity, and prevent side reactions or product quality problems caused by overheating.

[0003] Currently, existing cooling methods for water-reducing agents are mainly divided into jacketed reactor cooling and coil cooling. Jacketed reactor cooling involves setting a jacket around the reactor and circulating cooling water or chilled water. Heat exchange occurs between the jacket and the material inside the reactor. It has a simple structure and is easy to maintain, but its heat transfer efficiency is low and the cooling rate is slow. Coil cooling, on the other hand, involves installing spiral coils inside the reactor and circulating a cooling medium (water, ethylene glycol solution, etc.) to directly contact the water-reducing agent material for cooling. Its heat transfer efficiency is higher than that of the jacketed type. However, existing coils may affect the stirring effect on the water-reducing agent material, and because the coils are installed inside the reactor, subsequent cleaning is more troublesome.

[0004] Therefore, this application provides a cooling device for the production of water-reducing agents to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cooling device for the production of water-reducing agents to solve the problem that the existing water-reducing agent cooling schemes cannot achieve both high-efficiency cooling effect and convenient maintenance, and are prone to affecting the mixing effect of water-reducing agent materials.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A cooling device for water-reducing agent production includes a reaction vessel for mixing water-reducing agent materials. A coil is arranged in the middle of the reaction vessel, and a plurality of stirring rods are arranged around the edge of the coil. A support frame is arranged inside the coil, and the middle part of the support frame is fixed to the stirring shaft arranged in the middle of the reaction vessel. Water inlet pipes and water outlet pipes are arranged at both ends of the coil. Both the water inlet pipes and the water outlet pipes extend above the coil and are connected to a vertical water passage cylinder. The top of the water passage cylinder has an outlet that connects to the water outlet pipe, and the middle of the water passage cylinder has an inlet that connects to the water inlet pipe.

[0008] The reactor has an opening at the top and a lid is fixed thereon. A water receiving tube for inserting the water tube is fixed in the middle of the upper surface of the lid. The water receiving tube has two chambers, one above the other, that are connected to the outlet and the other to the inlet. Both chambers are connected to water pipes that extend out of the water receiving tube.

[0009] Optionally, the bottom edge of the reactor is fixed with multiple support legs, the bottom of the reactor is also equipped with a discharge pipe, and the inner wall of the middle part of the reactor is surrounded by a cooling jacket.

[0010] Optionally, a central disk is fixed at the bottom center of the support frame, and a reinforcing cylinder is fixed at the center of the central disk, with the reinforcing cylinder sleeved on the stirring shaft inside the reactor.

[0011] Optionally, a connecting cylinder is fixed to the lower end of the water-passing cylinder, and the connecting cylinder is sleeved on the top of the stirring shaft inside the reaction vessel.

[0012] Optionally, both the reinforcing cylinder and the docking cylinder are provided with fastening bolts.

[0013] Optionally, a servo motor is fixed in the middle of the bottom surface of the reactor. The shaft of the servo motor extends vertically into the reactor and is fixed to the lower end of the stirring shaft inside the reactor to form a drive.

[0014] Optionally, a sealed bearing is provided at the bottom of the water receiving cylinder for the water passing through, forming a sealed partition with the interior of the reaction vessel.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the cooperation between the coil and the support frame, it can be fixed on the stirring shaft inside the reactor. With the addition of the stirring rod, the coil can rotate with the stirring shaft inside the reactor to mix and stir the water-reducing agent material inside the reactor through the stirring rod. Furthermore, thanks to the cooperation between the water receiving tube and the water passage tube, coolant can be easily introduced into the coil, ensuring the mixing and cooling effects of the water-reducing agent material.

[0017] In the above solution, thanks to the fact that the coil is installed on the stirring shaft through the reinforcing cylinder and the connecting cylinder, it is easy to remove the coil from the stirring shaft after the kettle lid is opened, which is beneficial for later cleaning and maintenance.

[0018] In summary, this device can simultaneously ensure the mixing and cooling effects of water-reducing agent materials, and it is convenient to remove for cleaning and maintenance later, resulting in good overall performance. Attached Figure Description

[0032] like Figure 1-4 As shown, an embodiment of the present invention provides a cooling device for the production of water-reducing agents, including a reaction vessel 1 for mixing water-reducing agent materials. The bottom edge of the reaction vessel 1 is fixed with a plurality of support legs 101. A discharge pipe 102 is also installed at the bottom of the reaction vessel 1. A cooling jacket 103 is arranged around the inner wall of the middle part of the reaction vessel 1. The cooling jacket 103 can be connected to a coolant system to form a jacketed cooling system as described in the prior art.

[0033] A coil 4 is provided in the center of the reactor 1. Several stirring rods 5 are arranged around the edge of the coil 4. A support frame 7 is provided on the inner side of the coil 4. The center of the support frame 7 is fixed to the stirring shaft provided in the center of the reactor 1. Specifically, a servo motor 104 is fixed in the center of the bottom surface of the reactor 1. The shaft of the servo motor 104 extends vertically into the reactor 1 and is fixed to the lower end of the stirring shaft in the reactor 1 to form a drive. A central disk 701 is fixed in the center of the bottom end of the support frame 7. A reinforcing cylinder 702 is fixed in the center of the central disk 701. The reinforcing cylinder 702 is sleeved on the stirring shaft in the reactor 1.

[0034] Meanwhile, the coil 4 is provided with an inlet pipe 401 and an outlet pipe 402 at both ends. The inlet pipe 401 and the outlet pipe 402 both extend to the top of the coil 4 and are connected to a vertical water passage cylinder 6. The top of the water passage cylinder 6 is provided with an outlet 601 that connects to the outlet pipe 402, and the middle of the water passage cylinder 6 is provided with an inlet 602 that connects to the inlet pipe 401.

In a specific implementation, a sealed bearing is provided at the bottom of the water receiving tube 3 for the water tube 6 to pass through, forming a sealed partition with the interior of the reactor 1.

[0036] The working principle provided by this utility model is that, in use, the cooling device for water-reducing agent production involves installing the coil 4 on the stirring shaft inside the reaction vessel 1, and driving the stirring shaft to rotate the coil 4 via the servo motor 104. The coil 4 and the stirring rod 5 are used to mix and stir the water-reducing agent material inside the reaction vessel 1, ensuring the mixing effect.

[0037] Meanwhile, the water receiving cylinder 3 is connected to the coolant system through two water pipes 301, allowing coolant to circulate in the coil 4. The coil 4 directly contacts the water-reducing agent material, thereby further ensuring the cooling effect on the water-reducing agent material.

[0038] When cleaning is required later, the coil 4 can be easily removed from the stirring shaft by loosening or tightening the bolts on the connecting cylinder 603 and the reinforcing cylinder 702 after opening the lid 2, which is convenient for later cleaning and maintenance.
