Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology, specifically relating to an energy-saving circulating cooling water cooling device. Background Technology

[0002] In the production process of graphite electrodes, cooling devices are required to cool the electrodes. Traditional cooling devices simply immerse the electrodes directly in the coolant within a cooling tank. This can easily lead to collisions and damage between the electrodes. Furthermore, the electrodes remain stationary in the coolant, affecting heat exchange efficiency and resulting in poor cooling. Additionally, the lack of flow within the coolant tank leads to temperature variations throughout the tank, further impacting the cooling effect. Therefore, there is an urgent need for an energy-efficient circulating cooling water system to solve these technical problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an energy-saving circulating cooling water cooling device, including a cooling tank with a drain outlet at the bottom. The cooling tank contains a conveying assembly, which includes two drive chains and multiple storage slots between the two drive chains. Connecting blocks are fixedly connected to both ends of the multiple storage slots, and the connecting blocks are connected to the corresponding drive chains. The storage slots are covered with through holes.

[0004] The drive chain is equipped with four sprockets, which are distributed at the four corners of the same rectangle. Two sprockets are located at the bottom of the cooling box, and the other two are located outside the cooling box. One of the sprockets is connected to a motor. Two upper pressure rollers are provided between the two sprockets located outside the cooling box, both located inside the cooling box. Guide rollers are provided between the upper pressure rollers and the adjacent sprockets in the drive chain. The guide rollers guide and tension the drive chain.

[0005] By configuring the conveyor components, the electrodes to be cooled are placed in their respective slots. The conveyor components continuously transport the electrodes to the cooling tank for cooling, achieving continuous and efficient cooling operations. The cooling tank can be replenished with coolant as needed. Simultaneously, as the drive chain propels the slots within the cooling tank, it agitates the water, improving the efficiency of heat exchange between the coolant and the electrodes. This results in a more uniform temperature of the coolant within the cooling tank, further enhancing the cooling effect. The cooling tank can be cleaned periodically to remove any accumulated impurities from the bottom.

[0006] Preferably, the cooling tank is equipped with spray assemblies at both ends. Each spray assembly includes a mounting frame, a liquid guide pipe, and a liquid distribution pipe. Multiple liquid distribution pipes are distributed on the mounting frame, and multiple spray heads are mounted on each liquid distribution pipe. The spray heads are located above the conveying assembly. All liquid distribution pipes are connected to the liquid guide pipe, and a water pump is mounted on each liquid guide pipe. A liquid outlet pipe is located at the bottom of the cooling tank, and the lower end of the liquid guide pipe is connected to the liquid outlet pipe. A filter screen is mounted on the liquid outlet pipe. The filtered coolant enters the liquid distribution pipe under the action of the water pump and is then sprayed out from the spray heads to cool and rinse the electrodes in the storage tank, improving the cooling effect and reducing the adhesion of impurities to the electrodes.

[0007] Preferably, the spray assembly is positioned above the storage slot between the guide wheel and the adjacent sprocket. The spray assembly is located at both ends of the cooling tank, allowing for the circulation of the coolant within the tank. The coolant pre-cools the electrodes in the storage slot at the feed end of the cooling tank, preventing sudden cooling from adversely affecting the electrodes. It also rinses the electrodes in the storage slot at the discharge end of the cooling tank, further reducing impurities on the electrodes.

[0008] Preferably, the cooling box is equipped with a cooler. The cooler (water cooler / water-type cooler) can cool the water in the cooling box, thereby improving the cooling efficiency of the cooling box for the electrodes.

[0009] Preferably, the cooling box is equipped with a filter frame, and the storage groove between the two upper pressure rollers is located inside the filter frame. The filter frame can prevent impurities falling from the electrode from entering the filter frame and causing secondary contamination to the immersed electrode. At the same time, the filter frame is detachably installed in the cooling box, allowing for the cleaning of impurities inside the filter frame.

[0010] Preferably, the angle between the transmission chain between the upper pressure wheel and the adjacent guide wheel and the horizontal direction is no greater than 45°. Limiting the inclination angle of the transmission chain prevents the inclination angle of the storage groove between the upper pressure wheel and the guide wheel from being too large, which could cause the electrodes inside the storage groove to detach from the groove.

[0011] Preferably, the guide wheel is at the same height as the adjacent sprocket. This arrangement ensures that the storage slots between the guide wheels and sprockets at both ends of the cooling box are horizontal, forming horizontal loading and unloading sections, which facilitates loading and unloading.

[0012] This utility model also includes other components that enable the cooling device for energy-saving circulating cooling water to operate normally, such as the control components for the water pump, the control components for the motor, and the control components for the refrigeration unit, all of which are conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as motors, water pumps, spray heads, refrigeration units (water-type coolers), transmission chains, sprockets, upper pressure rollers, and guide rollers, all employ conventional technologies and equipment in the field.

[0013] Working Principle: Electrodes to be cooled are placed in their respective storage slots. A conveyor system continuously transports the electrodes to the cooling tank for cooling, achieving continuous and efficient cooling. The cooling tank can be replenished with coolant as needed. Simultaneously, the movement of the storage slots within the cooling tank, driven by a transmission chain, agitates the water, improving the efficiency of heat exchange between the coolant and the electrodes. This results in a more uniform temperature of the coolant within the cooling tank, further enhancing the cooling effect. During this process, spray units at both ends of the cooling tank pump the filtered coolant into the distribution pipes, which are then sprayed out from the spray nozzles to cool and rinse the electrodes in the storage slots, improving the cooling effect and reducing impurities adhering to the electrodes. The coolant is recyclable, making it more energy-efficient and effective.

[0014] This invention has the following advantages: it enables continuous and efficient cooling operations, sequentially pre-cooling, cooling, and rinsing the object to be cooled; it has good cooling effect and high cooling efficiency; during the cooling process, the electrodes move continuously, and the coolant is also stirred by the placement tank, further improving the cooling effect and uniformity; the coolant can be filtered and recycled, and impurities that fall off during cooling can be filtered to improve the cleanliness of the cooled object, making it energy-efficient and beneficial to production.

[0021] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0022] Example 1

[0023] like Figure 1-2 As shown, this utility model provides an energy-saving circulating cooling water cooling device, including a cooling tank 1. The bottom of the cooling tank is provided with a drain port. The cooling tank 1 is provided with a conveying component. The conveying component includes two transmission chains 3. Multiple storage slots 4 are arranged between the two transmission chains 3. The storage slots are semi-cylindrical in shape to match the electrodes. Connecting blocks 18 are fixedly connected to both ends of the multiple storage slots 4. The connecting blocks 18 are connected to the corresponding transmission chains 3. The storage slots 4 are covered with through holes.

[0024] The transmission chain 3 is equipped with four sprockets 5, which are distributed at the four corners of the same rectangle. Two sprockets 5 are located at the bottom of the cooling box 1, and the other two sprockets 5 are located outside the cooling box 1. One of the sprockets 5 is connected to a motor 16. The transmission chain 3 between the two sprockets 5 located outside the cooling box 1 is equipped with upper pressure rollers 6. There are two upper pressure rollers 6, both of which are located inside the cooling box 1. The transmission chain 3 between the upper pressure rollers 6 and the adjacent sprockets 5 is equipped with guide rollers 7. The guide rollers 7 can guide and tension the transmission chain 3. In this embodiment, the centers of the sprockets, upper pressure rollers, and guide rollers are all fixedly connected to shafts. The shafts connected to the sprockets inside the cooling box are rotatably connected to the cooling box through bearings. The other shafts are all connected to brackets, which are fixedly installed on both sides of the cooling box. One end of each shaft is rotatably connected to the corresponding bracket through a bearing (the brackets and their rotatable connection to the shafts are prior art, and their specific structure is not shown in the attached drawings). The upper pressure rollers and guide rollers are both sprocket structures that cooperate with the transmission chain.

[0025] By configuring the conveying components, the electrodes 15 to be cooled are placed in the respective storage slots 4. The conveying components continuously transport the electrodes 15 to the cooling tank 1 for cooling. The cooling tank contains coolant, which can be water, enabling continuous and efficient cooling. Coolant can be added to the cooling tank 1 as needed. Simultaneously, with the transmission chain 3, the storage slots 4 move within the cooling tank 1, agitating the water and improving the efficiency of heat exchange between the coolant and the electrodes 15. This results in a more uniform temperature of the coolant within the cooling tank 1, further enhancing the cooling effect. The cooling tank 1 can be cleaned periodically to remove impurities deposited at the bottom.

[0026] The cooling tank 1 is equipped with spray assemblies at both ends. Each spray assembly includes a fixing frame 8, a liquid guide pipe 9, and a liquid distribution pipe 11. The fixing frame 8 is fixed above the cooling tank 1 by a column 17. Multiple liquid distribution pipes 11 are distributed on the fixing frame 8, and multiple spray heads 10 are installed on each liquid distribution pipe 11. The spray heads 10 are located above the conveying assembly. All liquid distribution pipes 11 are connected to the liquid guide pipe 9, which is equipped with a water pump. A liquid outlet pipe 14 is located at the bottom of the cooling tank 1, and the lower end of the liquid guide pipe 9 is connected to the liquid outlet pipe 14. A filter screen 13 is installed on the liquid outlet pipe 14. The filtered coolant enters the liquid distribution pipe 11 under the action of the water pump and is then sprayed out from the spray heads 10, cooling and rinsing the electrodes 15 in the storage tank 4, improving the cooling effect and reducing the adhesion of impurities to the electrodes 15.

[0027] The spray assembly is positioned above the storage trough 4 between the guide wheel 7 and the adjacent sprocket 5. Located at both ends of the cooling tank 1, the spray assembly circulates the coolant within the cooling tank 1. The coolant pre-cools the electrodes 15 in the storage trough 4 at the inlet end of the cooling tank 1, preventing sudden cooling from adversely affecting the electrodes 15. It also rinses the electrodes 15 in the storage trough 4 at the outlet end of the cooling tank 1, further reducing impurities on the electrodes 15. The liquid guide pipe 9 at the outlet end of the cooling tank 1 is also connected to an inlet pipe 19, through which clean coolant can be introduced.

[0028] The cooling box 1 is equipped with a cooler 12. The cooler 12 (water cooler / water-type cooler) can cool the water in the cooling box 1, thereby improving the cooling efficiency of the cooling box for the electrode 15.

[0029] The angle between the transmission chain 3 between the upper pressure roller 6 and the adjacent guide roller 7 and the horizontal direction is no greater than 45°. The limitation of the tilt angle of the transmission chain 3 can prevent the tilt angle of the storage groove 4 between the upper pressure roller 6 and the guide roller 7 from being too large, which would cause the electrode 15 in the storage groove 4 to fall out of the storage groove 4.

[0030] The guide wheel 7 is at the same height as the adjacent sprocket 5. This arrangement ensures that the storage groove 4 between the guide wheels 7 and sprocket 5 at both ends of the cooling box 1 is in a horizontal state, forming a horizontal loading and unloading section, which facilitates loading and unloading.

[0031] Electrodes awaiting cooling are placed in their respective storage slots. A conveyor system continuously transports the electrodes to the cooling tank for cooling, achieving continuous and efficient cooling. The cooling tank can be replenished with coolant as needed. Simultaneously, the movement of the storage slots within the cooling tank, driven by a transmission chain, agitates the water, improving the efficiency of heat exchange between the coolant and the electrodes. This results in a more uniform temperature of the coolant within the cooling tank, further enhancing the cooling effect. During this process, spray units at both ends of the cooling tank pump the filtered coolant into the distribution pipes, which are then sprayed from the spray nozzles to cool and rinse the electrodes in the storage slots, improving the cooling effect and reducing impurities adhering to the electrodes. The coolant is recyclable, making it more energy-efficient and effective.

[0032] Example 2

[0033] like Figure 3-4 As shown, the difference between this embodiment and Embodiment 1 is that a filter frame 2 is provided inside the cooling box 1, and the storage groove 4 between the two upper pressure rollers 6 is located inside the filter frame 2. The filter frame 2 can prevent impurities falling from the electrode 15 from entering the filter frame 2 and causing secondary contamination to the immersed electrode 15. At the same time, the filter frame 2 is detachably installed inside the cooling box 1 (the edge of the filter frame can be hinged with a buckle 20, and the filter frame is attached to the cooling box by the buckle), which allows for the cleaning of impurities inside the filter frame 2.

[0034] Specifically, the filter frame is equipped with a matching soft filter screen II, which is detachably connected to the filter frame (such as by a strap), making it easy to remove the filter screen II for cleaning after a period of use.

[0035] The motor, water pump, spray head, upper pressure roller, guide roller, sprocket, transmission chain, and refrigeration unit (water cooler) involved in the above embodiments 1 and 2 are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical data, which are all existing technologies.

[0036] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
