Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a powder flow cooling water circulation device, including a cooling water outlet pipe 1 and a cooling water return pipe 2. The right end of the cooling water outlet pipe 1 is connected to the outlet of the circulation pump 3. The right end of the cooling water return pipe 2 is connected to a descaling tank 6. The right outer wall of the descaling tank 6 is connected to a connecting pipe 2 8. The right end of the connecting pipe 2 8 is connected to a connecting pipe 1 5. The top end of the connecting pipe 1 5 is connected to a three-way valve 4. One end of the three-way valve 4 is connected to the inlet of the circulation pump 3. An auxiliary cooling component 9 is provided outside the cooling water outlet pipe 1. One port of the three-way valve 4... A flushing pipe 7 is connected to a descaling tank 6 for removing scale from the returning cooling water and removing impurities in the cooling water, thereby preventing scale buildup in the pipeline. A three-way valve 4 is installed to connect the cooling water outlet pipe 1, the cooling water return pipe 2, the circulation pump 3, the flushing pipe 7, the connecting pipe 2 8, and the connecting pipe 1 5. Purified water can be periodically introduced from the flushing pipe 7 into the circulation pump 3, allowing the purified water to backwash the inside of the circulation pump 3 and the cooling water outlet pipe 1, further preventing scale buildup in the pipeline. The circulation pump 3 is also installed as an auxiliary pump to circulate the cooling water.

[0021] The descaling tank 6 includes a tank body 601, an electric dosing device 604, a cooling water return pipe 2, and a connecting pipe 8, both of which are connected to the inside of the tank body 601. The cooling water return pipe 2 is located near the bottom of the tank body 601, and the connecting pipe 8 is located near the top of the tank body 601. A filter chamber 602 is installed inside the tank body 601, located between the cooling water return pipe 2 and the connecting pipe 8. A dosing pipe 603 is connected to the outer side wall of the tank body 601, and the right end of the dosing pipe 603 is connected to the feed line of the electric dosing device 604. The outlet is connected, and the dosing pipe 603 is located below the filter chamber 602. The housing 601 is equipped with a stirring structure 605, which is located below the filter chamber 602. The filter chamber 602 is used to filter impurities in the cooling water. The dosing pipe 603 and the electric dosing device 604 are used to add descaling chemicals to further prevent the formation of scale. The stirring structure 605 is used to stir the chemicals in the housing 601 to ensure that the chemicals are fully mixed with the cooling water and to ensure the descaling effect.

[0022] The filter chamber 602 includes a mounting plate 6021, which is fixedly installed in the through hole on the front of the housing 601 by screws. A flow box 6022 is fixedly installed on the back of the mounting plate 6021. A filter element 6023 is installed inside the flow box 6022. The flow box 6022 is installed in the housing 601 by the mounting plate 6021. The flow box 6022 is used to install the filter element 6023. After a period of use, the screws on the mounting plate 6021 can be removed, and the flow box 6022 can be pulled out of the housing 601 by the mounting plate 6021. Then the filter element 6023 inside the flow box 6022 can be cleaned or replaced.

[0023] The filter element 6023 inside the flow box 6022 is equipped with three layers of multi-layer filtration to ensure the filtration effect. A sealing gasket 11 is provided at the connection between the mounting plate 6021 and the through hole on the box 601 to prevent cooling water from flowing out from the connection between the mounting plate 6021 and the box 601.

[0024] The stirring structure 605 includes a motor 6051, which is fixedly mounted on the bottom of the housing 601. A rotating shaft 6053 is fixedly mounted on the output end of the motor 6051. The rotating shaft 6053 passes through the bottom of the housing 601 via a sealed bearing. Stirring blades 6054 are fixedly mounted on the outer wall of the rotating shaft 6053. A protective cover 10 is fixedly mounted on the bottom of the housing 601. The protective cover 10 has water inlet and outlet holes. A waterproof packing 6052 is fixedly mounted on the inner wall of the bottom of the protective cover 10. The waterproof packing 6052 is located on the rotating shaft 6051. Within the gap between the root of 53 and the protective cover 10, the protective cover 10 is installed to install the waterproof filler 6052 and to protect the rotating shaft 6053 and the stirring blade 6054. The waterproof filler 6052 is installed to prevent cooling water from flowing out from the contact part between the rotating shaft 6053 and the sealed bearing. The rotating shaft 6053 is driven to rotate by the motor 6051, which in turn drives the stirring blade 6054 to rotate, so that the cooling water flowing through the inside of the protective cover 10 is stirred, thereby generating turbulence, so that the drug can be better mixed with the cooling water after contacting the turbulence.

[0025] The auxiliary cooling component 9 includes a heat-insulating shell 901. A cooler 902 is fixedly installed on the top inner wall of the heat-insulating shell 901. The heat exchange medium inlet and outlet of the cooler 902 are connected to a heat exchange medium circulation pipe 903. The heat exchange medium circulation pipe 903 is coiled around the cooling water outlet pipe 1. When the cooling water cannot reach the set temperature, the cooler 902 can be turned on to generate a low-temperature heat exchange medium. After the heat exchange medium flows through the heat exchange medium circulation pipe 903, it exchanges heat with the cooling water in the cooling water outlet pipe 1, so that the cooling water reaches the set temperature, thereby ensuring the cooling effect of the cooling water on the powder.

[0026] Working principle: When in use, turn the handle on the three-way valve 4 to connect the inlet of the circulating pump 3 to the connecting pipe 5, turn on the refrigeration equipment to make the cooling water circulate, and then cool the powder when it flows through the powder conveying pipe. After the cooling water returns to the tank 601 from the cooling water return pipe 2, it is filtered by the filter element 6023 and then returns to the cooling water outlet pipe 1 from the connecting pipe 8, connecting pipe 5, three-way valve 4, and circulating pump 3. At the same time, turn on the electric dosing device 604 to add descaling chemicals to the tank 601 at regular intervals. After the chemicals are mixed with the cooling water, scale formation is further prevented.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
