Description

Technical Field

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

[0002] Water-reducing agent cooling equipment is a special equipment used to cool down the high-temperature water-reducing agent during the production process, especially after the synthesis reaction. Its core function is to reduce the temperature of the water-reducing agent to a suitable range required for storage, transportation or subsequent processing through a reasonable cooling method, so as to ensure the stability, performance and shelf life of the water-reducing agent.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing water-reducing agent cooling equipment lacks a structure for multi-stage cooling of the coolant. As a result, in some equipment using a single cooling medium or a single cooling temperature, the initial temperature of the coolant is low. Upon contact with the high-temperature water-reducing agent, it rapidly absorbs heat, causing its temperature to rise quickly. Due to the lack of a multi-stage cooling structure, the coolant cannot maintain effective cooling capacity in the subsequent stages. Consequently, in the latter half of the cooling process, the temperature difference between the coolant and the water-reducing agent decreases, thereby reducing heat exchange efficiency.

[0004] To address this, a multi-stage gradient cooling device for polycarboxylate superplasticizer is proposed. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The multi-stage cooling mechanism of this application, through the design of three independent cooling chambers and the flow path of the water-reducing agent in the spiral tube, can cool the water-reducing agent in stages. Each cooling chamber can form a temperature gradient based on the cooling oil at different temperatures, such as a gradual transition from high temperature to low temperature, avoiding problems such as molecular chain breakage and performance degradation of the water-reducing agent due to excessive instantaneous temperature difference. It effectively ensures the core performance of polycarboxylate water-reducing agent such as dispersibility and slump retention. The spiral tube structure extends the flow path and heat exchange time of the water-reducing agent in the cooling chamber, allowing the water-reducing agent to fully contact the cooling oil and enhance the heat exchange effect. At the same time, the series design of multiple cooling chambers can amplify the cooling range step by step. Compared with a single cooling structure, it can reduce the temperature of the water-reducing agent to the target range faster, which is suitable for large-scale production needs. By controlling the opening and closing of the oil inlet pipe through the electromagnetic single-way valve, the cooling oil in each cooling chamber can be adjusted according to the real-time temperature of the cooling oil to achieve targeted cooling and improve the controllability of the cooling process.

[0018] 2. The circulation mechanism of this application forms a circulation system through an oil storage box, a circulation pump, an oil extraction pipe, and a connecting pipe, allowing the cooling oil to circulate between the cooling chamber and the oil storage box, avoiding waste of the cooling medium. At the same time, the semiconductor cooling plate cools the heated cooling oil a second time, allowing the cooling capacity of the cooling oil to be reused and reducing energy consumption. The semiconductor cooling plate inside the cooling shell can quickly reduce the temperature of the cooling oil circulating back to the oil storage box. Combined with the electric cooling fan, the heat dissipation is accelerated through the heat dissipation pipe, ensuring that the cooling oil entering the cooling chamber always maintains a suitable low temperature and ensuring the stability of the cooling effect at each stage.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A multi-stage gradient cooling polycarboxylate superplasticizer cooling device includes a workbench 1, a cooling tank 2 welded to the inner side of the top of the workbench 1, a multi-stage cooling mechanism 3 welded to the inner side of the cooling tank 2, and a circulation mechanism 4 installed on the right side of the top of the workbench 1. The multi-stage cooling mechanism 3 includes three cooling chambers 31, a feed pipe 32, a spiral pipe 33, an oil inlet pipe 34, an oil outlet pipe 35, and a solenoid single-way valve 36. The three cooling chambers 31 are respectively welded to the top, bottom, and inner side of the cooling tank 2. The feed pipe 32 is fixedly connected to the top and bottom of the top cooling chamber 31 and the top and bottom of the bottom cooling chamber 31. The spiral pipe 33 is installed on the inner side of the three cooling chambers 31.

[0029] In this embodiment: A workbench 1 provides a stable mounting platform for the cooling tank 2 and the circulation mechanism 4. The cooling tank 2, serving as the mounting carrier for the multi-stage cooling mechanism 3, provides a relatively independent space for the cooling of the water-reducing agent through its enclosed structure, reducing the interference of external ambient temperature on the cooling process. The multi-stage cooling mechanism 3, welded internally, forms an orderly cooling zone within itself, ensuring that the heat exchange between the cooling oil and the water-reducing agent occurs in a controllable environment, thus improving cooling efficiency. The three independent cooling chambers 31 can each form different temperature gradients, providing a phased cooling environment for the water-reducing agent, gradually reducing its temperature and minimizing the impact of temperature fluctuations on product performance. The feed pipe 32 enables the orderly transport of the water-reducing agent between different cooling chambers 31. The top and bottom connection design ensures that the water-reducing agent can smoothly enter the spiral tube 33, and the interconnected structure of the three spiral tubes 33 allows the water-reducing agent to continuously flow through each cooling chamber 31, ensuring the continuity of the cooling process and improving production efficiency. The spiral tube 33 extends the flow path and residence time of the water-reducing agent within the cooling chamber 31, increasing the contact area between the water-reducing agent and the cooling oil, and enhancing heat exchange. To improve the cooling effect and make the water-reducing agent cool more evenly, the oil inlet pipe 34 supplies cooling oil to the cooling chamber 31. Its cooperation with the distribution pipe 46 and the solenoid single-way valve 36 controls the amount and timing of cooling oil input to each cooling chamber 31, adjusting the cooling intensity according to the needs of different cooling stages and improving the targeted cooling. The oil outlet pipe 35 guides the cooled oil, after absorbing heat, from the cooling chamber 31 to the oil storage box 41, achieving the circulation and return of the cooling oil. The solenoid single-way valve 36 controls the opening and closing of the oil inlet pipe 34 and the connecting pipe 49 respectively. The cooling can be flexibly switched through the control of the PLC controller 7. The direction and flow rate of the oil enable independent control of the cooling oil supply to each cooling chamber 31. The discharge pipe 5 is used to discharge the cooled water-reducing agent from the cooling tank 2. The on / off valve 6 controls the opening and closing of the discharge pipe 5, and can control the discharge timing according to the cooling progress of the water-reducing agent to avoid premature discharge of the water-reducing agent that has not been fully cooled, thus ensuring product quality. The PLC controller 7 receives the detection data from the temperature sensor 8 and performs linkage control on components such as the electromagnetic single-way valve 36, the circulating pump 47, and the electric cooling fan 45 to realize the automation and intelligence of the cooling process and reduce human operation errors.

[0030] Specifically, such as Figure 2 As shown, the top of the spiral tube 33 is fixedly connected to the bottom of the feed pipe 32 at the top of the cooling chamber 31, and the three spiral tubes 33 are interconnected. The oil inlet pipe 34 is fixedly connected to the top of the left side of the cooling chamber 31, and the oil outlet pipe 35 is fixedly connected to the bottom of the right side of the cooling chamber 31. The electromagnetic single-way valve 36 is installed on the left side of the oil inlet pipe 34 and the rear side of the circulation mechanism 4, respectively. The bottom of the cooling tank 2 is fixedly connected to the discharge pipe 5, and the bottom of the discharge pipe 5 is equipped with an on / off valve 6. The front side of the top left side of the workbench 1 is equipped with a PLC controller 7.

[0031] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the circulation mechanism 4 includes three oil storage boxes 41, a cooling shell 42, several semiconductor cooling plates 43, three heat dissipation pipes 44, an electric cooling fan 45, a distribution pipe 46, a circulation pump 47, an oil extraction pipe 48, and a connecting pipe 49. The oil storage boxes 41 are installed on the right side of the top of the workbench 1.

[0032] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the right side of the oil outlet pipe 35 is fixedly connected to the left side of the oil storage box 41, the cooling shell 42 is welded to the inner side of the oil storage box 41, the semiconductor cooling plate 43 is installed on the inner side of the cooling shell 42, the heat dissipation pipe 44 is fixedly connected to the top of the cooling shell 42, and the top of the heat dissipation pipe 44 passes through the oil storage box 41 and extends to the outer side of the oil storage box 41.

[0033] In this embodiment: an oil storage box 41 is provided to store cooling oil and supply oil to the circulation mechanism 4. A filling pipe is fixedly connected to the top right side of the oil storage box 41, and a cap is snapped into the top of the inner side of the filling pipe for easy addition of cooling oil. The cooling shell 42 provides installation space for the semiconductor cooling plate 43, which can efficiently transfer the cooling capacity of the semiconductor cooling plate 43 to the cooling oil, improving cooling efficiency. The semiconductor cooling plate 43 utilizes the thermoelectric effect to quickly reduce the temperature of the cooling oil, which is more energy-efficient and has a faster response compared to traditional cooling methods. The cooling power can be adjusted in real time according to the cooling oil temperature to ensure the low-temperature effect of the cooling oil and meet the temperature requirements of the cooling medium for multi-stage cooling. The heat dissipation pipe 44 conducts the heat generated by the semiconductor cooling plate 43 during operation to the outside, preventing heat from accumulating in the oil storage box 41 and affecting the cooling efficiency. As a result, the electric cooling fan 45 is installed inside the heat dissipation pipe 44 to accelerate airflow, enhance the heat dissipation capacity of the heat dissipation pipe 44, and assist the semiconductor cooling plate 43 in reducing the temperature of the cooling oil. The distribution pipe 46 distributes the cooling oil delivered by the circulation pump 47 to each oil inlet pipe 34 to realize the distribution of cooling oil supply, which is convenient for individual control. The circulation pump 47 provides power for the circulation flow of cooling oil. The cooling oil in the oil storage box 41 is pumped into the cooling chamber 31 through the oil extraction pipe 48 and the distribution pipe 46 to ensure the continuous circulation of the oil circuit. The oil extraction pipe 48 extracts the cooling oil in the oil storage box 41 and delivers it to the circulation pump 47. The connecting pipe 49 connects the oil storage box 41 to the oil extraction pipe 48 to realize the delivery of cooling oil from the oil storage box 41 to the circulation pump 47. The installation of the electromagnetic one-way valve 36 can control its opening and closing, and adjust the circulation flow of cooling oil in conjunction with the circulation pump 47.

[0034] Specifically, such as Figure 3 , Figure 4 , Figure 5As shown, electric cooling fans 45 are installed at the bottom and top of the inner side of the cooling pipe 44, respectively. Diverter pipe 46 is fixedly connected to the left side of oil inlet pipe 34. Circulation pump 47 is installed on the rear side of the top left side of workbench 1. The bottom of diverter pipe 46 is fixedly connected to the front side of circulation pump 47. Oil suction pipe 48 is fixedly connected to the rear side of circulation pump 47. Connecting pipe 49 is fixedly connected to the bottom of the rear side of oil storage box 41. Electromagnetic single-way valve 36 is installed on the left side of oil inlet pipe 34 and the rear side of connecting pipe 49, respectively. The right side of oil suction pipe 48 is fixedly connected to the rear side of connecting pipe 49.

[0035] Specifically, such as Figure 3 As shown, temperature sensors 8 are installed on the left side of the cooling tank 2 and the right side of the oil storage box 41. The detection end of the right side of the temperature sensor 8 passes through the cooling tank 2 and extends to the inside of the cooling chamber 31.

[0036] In this embodiment: by setting a temperature sensor 8, the temperature of the cooling oil inside the cooling chamber 31 and the oil storage box 41 can be monitored in real time, and the monitoring data can be fed back to the PLC controller 7.

[0037] Specifically, such as Figure 2 , Figure 3 As shown, the inner sides of the oil storage box 41 and the cooling cavity 31 are filled with cooling oil, and the inner walls of the oil storage box 41 and the cooling cavity 31 are coated with heat-insulating paint.

[0038] Specifically, such as Figure 3 As shown, a sealing ring 9 is welded at the connection between the oil outlet pipe 35 and the oil storage box 41, and the surface of the sealing ring 9 is coated with anti-corrosion paint.

[0039] In this embodiment: by providing cooling oil, which serves as a cooling medium, and possessing excellent thermal conductivity, the cooling oil can efficiently exchange heat with the water-reducing agent to achieve the purpose of cooling. By providing heat-insulating coating, the influence of the external ambient temperature on the internal temperature of the cooling chamber 31 and the oil storage box 41 can be effectively reduced, preventing heat from entering or leaving, maintaining the stability of the internal temperature, and ensuring the cooling efficiency of the cooling oil. By providing sealing ring 9, the connection between the oil outlet pipe 35 and the oil storage box 41 can be tightly fitted, effectively preventing leakage of cooling oil during circulation and reducing the loss of cooling oil. By providing anti-corrosion coating, the cooling oil can be resisted from corrosion, extending the service life of sealing ring 9.

[0040] Specifically, such as Figure 4 As shown, filter rings 10 are snapped into the bottom and top of the inner side of the heat pipe 44, and the surface of the filter rings 10 is coated with anti-corrosion paint.

[0041] Specifically, such as Figure 1 As shown, a support column 11 is welded to the chamfer at the bottom of the workbench 1, and the bottom of the support column 11 is engraved with anti-slip texture.

[0042] In this embodiment: by setting a filter ring 10, the air entering the heat dissipation pipe 44 can be filtered, blocking dust, impurities and other contaminants in the air from entering the heat dissipation pipe 44. By setting an anti-corrosion coating, its corrosion resistance can be improved, making it less susceptible to corrosion and damage in environments in contact with air, thus extending the replacement cycle. By setting a support column 11, the workbench 1 is provided with stable support. By setting an anti-slip texture, the friction between the workbench and the ground is increased, which can effectively prevent the equipment from shifting due to vibration or other reasons during operation.

[0043] Working principle: First, the operator activates the temperature sensor 8 via the PLC controller 7. The temperature sensor 8 detects the temperature of the cooling oil in the three cooling chambers 31. Simultaneously, it detects the temperature of the cooling oil in the corresponding oil storage box 41. Next, the PLC controller 7 controls the semiconductor cooling plate 43 to start, and the cooling shell 42 will exchange heat with the cooling oil in the oil storage box 41. When the temperature sensor 8 detects that the cooling oil inside the oil storage box 41 has reached the temperature of the corresponding cooling chamber 31, it transmits a signal to the PLC controller 7, and the PLC controller 7 starts the circulation pump 47. The electromagnetic one-way valves 36 on both sides of the corresponding pipeline are activated. The circulating pump 47 delivers cooling oil to the inside of the corresponding cooling chamber 31 through the connecting pipe 49, the oil suction pipe 48, the diverter pipe 46, and the oil inlet pipe 34. When the temperature inside the corresponding cooling chamber 31 drops to the required temperature, the temperature sensor 8 transmits a signal to the PLC controller 7. The PLC controller 7 closes the electromagnetic one-way valves 36 on both sides and opens the electromagnetic one-way valves 36 corresponding to the remaining two cooling chambers 31. The circulating pump 47 delivers cooling oil to these two cooling chambers 31 through the corresponding pipelines, realizing the exchange of cooling oil. At this time, the operator will... The polycarboxylate superplasticizer to be cooled is fed into the equipment through the feed pipe 32 of the top cooling chamber 31. Under the action of gravity, the superplasticizer enters three interconnected spiral tubes 33 in sequence, and begins to flow and cool within the cooling chamber 31. Then, the cooling oil in the top cooling chamber 31 first cools the high-temperature superplasticizer, while the cooling oil in the middle and bottom cooling chambers 31 achieves further cooling through a lower temperature gradient. Utilizing the extended contact path and area of ​​the spiral tubes 33, uniform heat dissipation of the superplasticizer is ensured. Then, the cooled oil, after absorbing heat, flows back to the oil storage box 41 through the oil outlet pipe 35. The oil storage box 41 contains a semi-finished... With the assistance of the cooling shell 42, the semiconductor cooling plate 43 cools the heated cooling oil again. At the same time, the electric cooling fan 45 dissipates the heat generated by the semiconductor cooling plate 43 through the heat dissipation pipe 44, so that the cooling oil can quickly return to the required low temperature state and prepare for the next cycle. Then, as the water-reducing agent continues to flow in the spiral tube 33, it gradually reaches the target temperature after three stages of gradient cooling. Finally, when the water-reducing agent is completely cooled and flows through the bottom cooling chamber 31, the operator opens the on / off valve 6 on the discharge pipe 5 through the PLC controller 7, and the cooled water-reducing agent is discharged from the equipment through the discharge pipe 5.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
