Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a rapid cooling device for the production of liquid sodium silicate. Background Technique

[0002] Sodium silicate, commonly known as water glass and glass glue, is a colorless [1], transparent viscous solid. Its aqueous solution is commonly known as water glass and is a mineral binder. It is a soluble inorganic silicate with a wide range of uses. Sodium silicate is the most valuable filler in the soap industry. Incorporating sodium silicate into laundry soap can buffer the alkalinity of the laundry soap, reduce the loss of the laundry soap in water, enhance the washing ability and prevent the soap from rancidity; sodium silicate plays the role of assisting washing, anti-corrosion and stabilizing foam in synthetic detergents; it can be used as a filler for papermaking; it is used to manufacture silica gel and silica; it is used as a binder in the foundry industry to bond sand and clay to make various molds and cores required by people.

[0003] During the production of liquid sodium silicate, it is necessary to continuously cool the transported liquid sodium silicate. After patent retrieval, it is found that a circulating cooling device for the production of sodium silicate with the publication number of CN219390211U can divide the liquid sodium silicate by setting multiple shunt pipes in the cooling cavity, increasing the heat exchange area between the cooling liquid in the cooling cavity and the liquid sodium silicate in the shunt pipes, thereby improving the cooling effect on the liquid sodium silicate. The cooling inner pipe in the shunt pipe can cool the inside of the liquid sodium silicate. The above-mentioned comparative document disperses the liquid sodium silicate through an impeller, but it cannot achieve the position exchange of the liquid sodium silicate, resulting in most of the liquid sodium silicate not being able to contact the cooling inner pipe, and there is a poor cooling efficiency.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , including: a cooling feed pipe 1, an auxiliary cooling bin 4 arranged on one side of the cooling feed pipe 1, a fitting sleeve 2 arranged between the cooling feed pipe 1 and the auxiliary cooling bin 4, and a heat exchange box 14 installed above the fitting sleeve 2. The heat exchange box 14 is internally provided with multiple groups of cooling plates, so that the relatively high temperature discharged into the heat exchange box 14 through the return pipe 13 is cooled and then discharged into the closed side cover 3 through another group of return pipes 13. The cooling feed pipe 1 and the auxiliary cooling bin 4 are oppositely distributed, and fitting sleeves 2 with the same structure are fixedly arranged on the opposite sides of the cooling feed pipe 1 and the auxiliary cooling bin 4. At the same time, two groups of assembly clamping plates 9 are arranged in a vertically opposite manner between the two groups of fitting sleeves 2, so that there is a space between the two groups of assembly clamping plates 9 that can accommodate the closed side cover 3. And screw holes are arranged on the surface of the closed side cover 3, and screw holes corresponding to the closed side cover 3 are also configured on the surface of the assembly clamping plate 9. During assembly, the closed side cover 3 is placed at the space on both sides of the assembly clamping plate 9, and the screw holes are aligned. Then, the closed side cover 3 can be fixed between the two groups of fitting sleeves 2 through bolts. Through the detachable method of the closed side cover 3, it is convenient to clean the cooling diversion pipe 6 subsequently.

[0027] One end of the stirring screw 7 is driven by a driving motor 8. The surface of the driving motor 8 is fixed to the inner wall of the auxiliary cooling bin 4 through a bracket. Through the driving of the driving motor 8, the stirring screw 7 can rotate, and the stirring screw 7 does not contact the annularly arrayed cooling diversion pipes 6. Therefore, as the stirring screw 7 rotates. The liquid sodium silicate gathered in the closed side cover 3 can be slowly stirred, so that the liquid sodium silicate can be repeatedly adjusted in position inside the closed side cover 3, enabling the liquid sodium silicate located in the center and the periphery to exchange positions, thereby improving the heat exchange quality with the cooling diversion pipe 6 and enhancing the cooling efficiency.

[0028] The two ends of the annularly distributed cooling diversion pipe 6 extend to one side through the connecting through pipes 11 respectively, and the other end of the connecting through pipe 11 is connected with a communicating ring part 12. The communicating ring part 12 is in an annular hollow shape, and can be communicated with the cooling diversion pipe 6 through the communicating ring part 12 and multiple groups of connecting through pipes 11. Both the communicating ring part 12 and the connecting through pipes 11 are arranged in two groups on both sides of the closed side cover plate 3 and are communicated with the cooling diversion pipe 6. One set of the fitting sleeves 2 is located in the middle and lower part of the cooling feed pipe 1, and the other set of the fitting sleeves 2 is located in the middle and upper part of the closed side cover plate 3, so that the closed side cover plate 3 is inclined between the cooling feed pipe 1 and the auxiliary cooling bin 4. Since heat moves upward, this inclined design enables the heat to be discharged from the cooling feed pipe 1 to the auxiliary cooling bin 4 as much as possible.

[0029] Another part of the return pipe 13 can be used as a support column for the auxiliary cooling bin 4. Through the support of the return pipe 13, the heat exchange box 14 is erected above the closed side cover plate 3. A cooling discharge pipe 5 is fixedly installed at one end of the auxiliary cooling bin 4 away from the closed side cover plate 3, and the cooling discharge pipe 5 is located in the middle and lower part of the auxiliary cooling bin 4. Therefore, there is a relatively large space inside the auxiliary cooling bin 4. The liquid sodium silicate discharged inside the closed side cover plate 3 will be discharged to the cooling discharge pipe 5 in the auxiliary cooling bin 4. The upper part of the end face of the auxiliary cooling bin 4 close to the cooling discharge pipe 5 is communicated with a cold air discharge pipe 15. The end of the cold air discharge pipe 15 is connected to the heat exchange box 14. The position of the cold air discharge pipe 15 is higher than the discharge position of the cooling discharge pipe 5. A refrigerator 16 is installed inside the cold air discharge pipe 15. The cold air generated by the refrigerator 16 can enter the auxiliary cooling bin 4 along the cold air discharge pipe 15 to perform secondary cooling on the liquid sodium silicate, further improving the cooling efficiency. A valve is arranged at the bottom end of the cold air discharge pipe 15 for convenient operation.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
