If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] See also Figure 1-4 The utility model provides a technical solution: a building gypsum powder homogenizing and cooling device, comprising a gypsum powder cooling chamber 1, a cold water tank 2 is fixedly connected to the surface of the gypsum powder cooling chamber 1, a gypsum powder feeding pipe 3 is fixedly connected to the upper end of the gypsum powder cooling chamber 1, a gypsum powder discharging pipe 4 is fixedly connected to the lower end of the gypsum powder cooling chamber 1, a water inlet pipe 5 is fixedly connected to the upper end of the cold water tank 2, a drain pipe 6 is fixedly connected to the right end of the cold water tank 2, a cooling component is arranged inside the gypsum powder cooling chamber 1, and an air cooling component is arranged on the surface of the cold water tank 2.

[0032] The cooling component includes a gypsum powder guide plate 11, which is rotatably connected to the inside of the gypsum powder cooling chamber 1. The surface of the gypsum powder guide plate 11 is adhered with thermal conductive silicone grease. The inner wall of the gypsum powder cooling chamber 1 is rotatably connected to an electric telescopic rod 16. The output end of the electric telescopic rod 16 is rotatably connected to the lower end of the gypsum powder guide plate 11. A heat exchange tube 12 is fixedly connected to the inside of the gypsum powder guide plate 11. The two ends of the heat exchange tube 12 are respectively fixedly connected to a first connecting tube 13 and a second connecting tube 14. The first connecting tube 13 and the second connecting tube 14 both extend out of the gypsum powder guide plate 11, and the heat exchange tube 12 is wavy.

[0033] There are four cooling components, which are staggeredly arranged inside the gypsum powder cooling chamber 1.

[0034] The air cooling component includes a third connecting pipe 15, which is fixedly connected to the left end of the cold water tank 2. The right end of the cold water tank 2 is fixedly connected to a water pump 10. The input end of the water pump 10 extends to the interior of the cold water tank 2. The output end of the water pump 10 is fixedly connected to a heat dissipation pipe 8. The surface of the heat dissipation pipe 8 is fixedly connected to a plurality of heat sinks 9 in a linear array. The left and right surfaces of the gypsum powder cooling chamber 1 are respectively fixedly connected to heat dissipation fans 7.

[0035] There are two cold water tanks 2, which are symmetrically arranged on the front and rear surfaces of the gypsum powder cooling chamber 1. There are two air cooling components, which are symmetrically arranged on the surfaces of the two cold water tanks 2. The two heat dissipation pipes 8 are fixedly connected to the corresponding third connecting pipes 15 respectively.

[0036] The four first connecting pipes 13 and the four second connecting pipes 14 all penetrate the gypsum powder cooling chamber 1 and extend to the inside of the corresponding cold water tank 2 respectively.

[0037] When using the cooling device, first add gypsum powder from the gypsum powder inlet pipe 3, start the electric telescopic rod 16 to adjust the inclination angle of the gypsum powder guide plate 11, and adjust the flow speed of the gypsum powder to facilitate the flow of the gypsum powder under its own gravity. In addition, multiple flows increase the contact area with the gypsum powder guide plate 11. Since the surface of the gypsum powder guide plate 11 is bonded with thermal conductive silicone grease, the thermal conductive silicone grease has good thermal conductivity, so that the heat of the gypsum powder itself is conducted to the gypsum powder guide plate 11, and then the heat is absorbed by the heat exchange tube 12 inside the gypsum powder guide plate 11 and transferred to the cold water inside the heat exchange tube 12, so as to facilitate uniform cooling of the gypsum powder.

[0039] After being cooled by a plurality of gypsum powder guide plates 11 , the gypsum powder falls to the gypsum powder discharge pipe 4 at the bottom of the gypsum powder cooling chamber 1 and is discharged through the gypsum powder discharge pipe 4 .

[0040] Furthermore, compared with the existing gypsum powder cooling method, the cooling water is cooled and circulated through the heat exchange tube 12, the heat dissipation tube 8, the heat sink 9 and the heat dissipation fan, which is convenient for uniform cooling of the gypsum powder, and the cooling speed is fast, thereby improving the cooling effect of the gypsum powder. The uniform cooling can make the gypsum powder fully crystallize and harden, thereby improving its strength, improving the quality of the gypsum powder, realizing the recycling of water resources, and saving water resources.

[0041] By applying thermal grease to the surface of the gypsum powder guide plate 11, the thermal conductivity of the gypsum powder guide plate 11 can be improved, which facilitates the transfer of heat from the gypsum powder to the gypsum powder guide plate 11. The inclination angle of the gypsum powder guide plate 11 can be adjusted by the electric telescopic rod 16 to facilitate the adjustment of the flow speed of the gypsum powder, thereby ensuring that the gypsum powder flows through the gypsum powder guide plate 11 more evenly, thereby improving the cooling efficiency.

[0042] Working principle: When using the cooling device, first add gypsum powder from the gypsum powder inlet pipe 3, start the electric telescopic rod 16 to adjust the inclination angle of the gypsum powder guide plate 11, and adjust the flow speed of the gypsum powder to facilitate the flow of the gypsum powder under its own gravity. In addition, multiple flows increase the contact area with the gypsum powder guide plate 11. Since the surface of the gypsum powder guide plate 11 is bonded with thermal conductive silicone grease, the thermal conductive silicone grease has good thermal conductivity, so that the heat of the gypsum powder itself is conducted to the gypsum powder guide plate 11, and then the heat is absorbed by the heat exchange tube 12 inside the gypsum powder guide plate 11 and transferred to the cold water inside the heat exchange tube 12, so as to facilitate uniform cooling of the gypsum powder.

[0043] Start two water pumps 10 to circulate and cool the cooling water inside the two cold water tanks 2. The water pump 10 pumps the cooling water to the heat pipe 8 for heat dissipation, and performs auxiliary heat dissipation through the heat sink 9. Start the cooling fan 7 to perform secondary heat dissipation on the heat pipe 8 and the heat sink 9. By circulating the cooling water inside the two cold water tanks 2, the recycling of water resources is achieved, saving water resources.

[0044] After being cooled by a plurality of gypsum powder guide plates 11 , the gypsum powder falls to the gypsum powder discharge pipe 4 at the bottom of the gypsum powder cooling chamber 1 and is discharged through the gypsum powder discharge pipe 4 .

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
