Description

Technical Field

[0002] A powder flow cooling system generally refers to a combination of engineering equipment used to reduce the temperature of powder materials. Such systems are widely used in industrial production, especially in situations where it is necessary to control the material temperature to protect product quality or prevent equipment overheating.

[0003] A powder flow cooling system with water circulation is an industrial cooling system that uses circulating water as a cooling medium to reduce the temperature of powder materials. The powder materials flow in a cooler and exchange heat with the circulating water through a heat exchange surface. The powder releases heat, the water temperature rises, and the heated water is pumped to a cooling tower or cooling device to release heat and then cooled, and then recycled back to the cooler. By adjusting the flow rate and temperature of the circulating water, the control system can accurately control the cooling degree of the powder materials.

[0004] In the prior art, the Chinese utility model patent with the authorization announcement number: CN208872153U discloses a powder flow heat exchange device.

A motor is arranged inside the water tank, and the motor is connected to a stirring blade to stir the water. At the same time, a fan is also arranged on the water tank to blow air into the water tank to make the water dissipate heat quickly. Although this device solves the problem that the water temperature of the circulating water in the powder flow heat exchanger will gradually rise and the heat exchange becomes worse, this device uses water as a coolant, and various impurities are contained in the water, which will cause corrosion of the pipeline and scaling and blockage of the internal pipeline of the powder flow cooler, thus affecting the cooling effect.

[0025] In order to more clearly describe the present utility model, the present utility model will be further described below with reference to the drawings.

[0026] In the following description, example details are given to provide a deeper understanding 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. It should be understood that the specific embodiments are only used to explain the present utility model and are not used to limit the present utility model.

[0027] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, wholes, steps, operations, elements, or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, or combinations thereof.

[0028] Please refer toFigure 1 , a powder flow cooling system of the present utility model includes a powder flow cooler 9. A first cooling pipe 6 is installed inside the powder flow cooler 9. The first cooling pipe 6 is provided with a first water inlet 62 and a first water outlet 61. Both the first water inlet 62 and the first water outlet 61 penetrate through the powder flow cooler 9 and reach the outside of the powder flow cooler 9. It further includes a coolant storage tank 7. The coolant storage tank 7 is provided with a tank water inlet 71 and a tank water outlet 72. The tank water inlet 71 is communicated with the first water outlet 61, and the tank water outlet 72 is communicated with the first water inlet 62.

[0029] This powder flow cooling system cools the powder flow by arranging the first cooling pipe 6 inside the powder flow cooler 9. The powder flow to be cooled is added into the powder flow cooler 9 and comes into contact with the first cooling pipe 6 inside the powder flow cooler 9. Heat is transferred to the first cooling pipe 6 through heat exchange. The first cooling pipe is filled with continuously circulating coolant 73, and the coolant 73 is stored in the coolant storage tank 7.

[0030] Please refer to Figure 2 , in order to improve the heat exchange efficiency between the powder flow and the first cooling pipe 6, in the present utility model, a first cooling part is arranged between the first water inlet 62 and the first water outlet 61 of the first cooling pipe 6. The first cooling part is composed of a plurality of splints connected in series. A cavity is left inside the plurality of splints to connect the first water outlet 61 and the first water inlet 62. Setting the cooling part of the first cooling pipe 6 as a plurality of splints connected in series greatly increases the contact area between the cooling part of the first cooling pipe 6 and the powder flow, improves the heat exchange efficiency, and enables the powder flow to obtain a better cooling effect.

[0031] Please refer to Figure 1 and Figure 3, in the present utility model, there are further included a second cooling pipe 8 and a circulating water tank 3. The second cooling pipe 8 is installed inside the coolant storage tank 7. The second cooling pipe 8 is provided with a second water inlet 82 and a second water outlet 81, and both the second water inlet 82 and the second water outlet 81 penetrate through the coolant storage tank 7 and reach the outside of the coolant storage tank 7. The circulating water tank 3 is provided with a water injection port 31, a tank body water inlet 32 and a tank body water outlet 33. The water injection port 31 is connected to the tap water source 1. The tank body water inlet 32 communicates with the second water outlet 81, and the tank body water outlet 33 communicates with the second water inlet 82. Between the second water inlet 81 and the second water outlet 82 of the second cooling pipe 8 is set as the second cooling part, and the structure of the second cooling part is designed as a spring shape and there is a cavity inside the spring-shaped structure for connecting the second water outlet 81 and the second water inlet 82. Since the first cooling pipe 6 exchanges heat with the powder fluid, the temperature of the coolant in the first cooling pipe 6 rises. The coolant 73 with the increased temperature flows back to the coolant storage tank 7. If the coolant 73 in the coolant storage tank 7 is not cooled down, it will affect the subsequent cooling efficiency of the first cooling pipe 6 for the powder fluid. Therefore, in order to cool down the coolant 73, the second cooling pipe 8 is installed inside the coolant storage tank 7. The second cooling pipe 8 is connected to the circulating water tank 3, and the tap water 11 in the circulating water tank 3 flows through the second cooling pipe 8 to cool down the coolant 73. At the same time, in order to improve the heat exchange efficiency between the second cooling pipe 8 and the coolant 73, the structure of the cooling part of the second cooling pipe 8 is set as a spring shape to increase the contact area between the second cooling pipe 8 and the coolant 73, thereby improving the cooling efficiency.

[0032] Please refer to Figure 1 , in order to prevent the tap water 11 from causing scale and corrosion to the circulating water tank 3 and the second cooling pipe 8, in the present utility model, there are further included two siliphos medicine tanks 2. The two siliphos medicine tanks 2 are connected in series and installed between the tap water source 1 and the water injection port 31 to filter the tap water 11 injected into the circulating water tank 3. Siliphos dissolves in water and can react with metal ions such as calcium and magnesium to form soluble complexes, inhibiting the production of calcium salts and magnesium salts. At the same time, it can also react with iron ions to form a protective film on the pipe wall, effectively achieving the purpose of anti-corrosion and anti-scale.

[0033] In order to smoothly transport the tap water 11 in the circulating water tank 3 and the coolant 73 in the coolant storage tank 7 to the second cooling pipe 8 and the first cooling pipe 6 respectively, in the present utility model, there are further included a first water pump 51 and a second water pump 52. One end of the first water pump 51 is connected to the tank body water inlet 32, and the other end is connected to the second water inlet 82. One end of the second water pump 51 is connected to the tank body water outlet 72, and the other end is connected to the first water inlet 62. The circulation of the transported liquid is maintained by the first water pump 51 and the second water pump 52, and the flow rate of the transported liquid is controlled to ensure the normal operation of the system.

[0034] In order to further improve the cooling efficiency of the coolant 73 in the coolant storage tank 7, in the present utility model, the circulating water tank 3 is arranged as a closed-circuit cooling water tank. An air outlet 4 is provided at the top of the circulating water tank 3, and a blowing device is installed at the air outlet 4 to cool the tap water 11 in the circulating water tank 3. The circulating water tank 3 arranged as a closed type can prevent dust in the air from falling into the water tank and affecting the performance of the circulating water tank 3. At the same time, the tap water 11 in the circulating water tank 3 is used to cool the coolant in the coolant storage tank 7, which causes the temperature of the tap water 11 to rise. When the water temperature of the tap water 11 is too high, it affects the cooling efficiency. An air outlet 4 and a blowing device are provided at the top of the circulating water tank 3 for cooling the tap water 11.

[0035] In order to prevent scale formation and pipeline corrosion in the circulating water tank 3, the first cooling pipeline 6, the coolant storage tank 7, and the second cooling pipeline 8, both the first cooling pipeline 6 and the second cooling pipeline 8 are made of stainless steel. Stainless steel can effectively prevent the pipeline from rusting and avoid the pipeline from being corroded and affecting the cooling effect. The coolant 73 in the coolant storage tank 7 is antifreeze. Using antifreeze instead of water can prevent the coolant in the cooling system from freezing in a low-temperature environment; antifreeze has a higher boiling point than water, reducing the pressure in the cooling system and improving the cooling efficiency; antifreeze contains preservatives, which can prevent metal components in the cooling system from corroding; antifreeze can reduce the formation of scale, keep the cooling system clean, and avoid reducing the heat dissipation efficiency due to scale accumulation; the chemical properties of antifreeze are more stable than those of tap water 11, not easily deteriorated, with a long service life, and reducing the replacement frequency.

[0036] Example:

[0037] Technical transformation was carried out on the powder flow cooling water tower in a certain workshop:

[0038] Before the transformation, groundwater was used as the coolant to cool the powder flow. The groundwater was stored in the circulating water tank 3. The circulating water tank 3 was a self-made cement-poured open water tank with no shelter at the upper part, and the circulating water tank 3 was about 800 meters away from the powder flow cooler 9 in the workshop. The water delivery pipeline of the circulating water tank 3 was long and narrow. Before the transformation, dust fell into the circulating water tank 3, resulting in poor water quality, causing pipeline blockage, and thus affecting the circulation speed and cooling effect; the distance between the circulating water tank 3 and the powder flow cooler 9 was too large. During the process of pipeline transportation of circulating water, the water temperature of the pipeline would rise by 0.5 degrees Celsius due to sun exposure, affecting the cooling efficiency; the circulating water tank 3 used the company's groundwater, and the groundwater was directly used without treatment, resulting in serious corrosion of the circulating water tank 3 and pipelines, often leading to pipeline leakage points and increasing the maintenance cost; when using groundwater as the coolant, the groundwater quality was poor, often causing blockage of the internal pipelines of the powder flow cooler 9 due to scale formation, and at the same time, heat preservation cotton needed to be installed on the pipeline in winter to avoid pipeline freezing.

[0039] After the transformation, the circulating water tank 3 is changed to a closed stainless steel circulating water tank, which solves the problem of rust in the circulating water tank 3 and the pipeline; the circulating water tank 3 is installed on the second-floor platform of the workshop, 75 meters away from the powder flow cooler 9 in the workshop, the circulating pipeline is shortened by 725 meters, the energy loss during the circulation process is reduced by 90%, and the circulating cooling effect is improved by 15%; the circulating water tank 3 is externally connected to the tap water source 1, and two siliphos medicine tanks 22 are installed at the tap water source 1 and the water injection port 31 to filter the tap water 11, further solving the problems of scaling and rust in the pipeline; a coolant storage tank 7 is arranged between the circulating water tank 3 and the powder flow cooler 9, and antifreeze is used to cool the powder flow, while the tap water 11 is used to cool the antifreeze. The antifreeze is used as the cooling circulation medium for cooling the powder flow, effectively preventing the phenomena of pipeline structure and corrosion. At the same time, the high boiling point of the antifreeze can ensure that the pipeline will not be frozen in winter and affect the normal use of the system.

[0040] Application effect after transformation: The cooling effect is improved by 30%; the outlet temperature of the powder flow material is reduced by 8.39 °C compared with that before the transformation; the packaging temperature drops by 3 - 5 °C; the anti-caking effect of the product is improved, and the amount of anti-caking agent used can be reduced by 10% for the powder flow after the transformation; the packaging temperature from June to August in 2022 is 42 - 45 degrees. To ensure that the product quality does not cake, the average hourly feeding amount is 29 tons / hour. After the transformation, the packaging temperature from June to August in 2023 is 37 - 39 degrees, the average hourly feeding amount is 32.3 tons / hour, the hourly feeding amount increases by 3.3 tons / hour, and the average monthly production is 42 shifts, with the monthly production capacity increased by 1663.2 tons.

[0041] The advantages of the present utility model are as follows:

[0042] 1. By setting a circulating water tank, a second cooling pipeline, a coolant storage tank, a first cooling pipeline and a powder flow cooler, using tap water to cool the coolant and then using the coolant to cool the powder flow, it changes the previous technology of using water to cool the powder flow, effectively improving the cooling efficiency of the powder flow.

[0043] 2. By setting siliphos medicine tanks and using siliphos to treat tap water, it effectively avoids the problems of rust and scale in the circulating water tank and the second cooling pipeline.

[0044] 3. By setting a closed circulating cooling water tank, an exhaust port and a blowing device, it avoids dust from falling into the circulating water tank and affecting the water quality, and avoids the circulating water tank having too high a temperature and affecting the cooling efficiency.

[0045] The above only discloses several specific embodiments of the present utility model, but the present utility model is not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
