Description

Technical fields:

[0001] This utility model relates to the field of calcium carbide production, specifically to a circulating water cooling system for calcium carbide production. Background technology:

[0002] The calcium carbide furnace is the main equipment for producing calcium carbide. Inside the furnace, the high temperature generated by the electric arc melts the furnace charge, causing a reaction that produces calcium carbide. Because the reaction temperature reaches over 2000℃, most refractory materials cannot withstand such high temperatures. Therefore, the furnace volume must be larger than the reaction space. In other words, a layer of furnace charge should be left between the reaction zone and the furnace lining to protect the lining.

[0003] During the production process of calcium carbide in the furnace, heat is generated by the electrodes. In order to ensure the temperature of the electrodes when the furnace is opened, a circulating water cooling system is installed to ensure the normal production of the calcium carbide furnace.

[0004] After initial filtration, a certain amount of mixed medicine is added to the circulating water to increase the overall heat exchange effect. Then it enters the cold water pool, undergoes secondary filtration through a filter, and enters the calcium carbide furnace for cooling. After circulating out of the calcium carbide furnace, it enters the hot water pool and is then pumped to the cooling tower by a circulating pump. After cooling, it returns to the cold water pool. The backwash water from the filter also enters the cold water pool after side filtration and is recycled.

[0005] However, during the dosing process, the traditional dosing method involves directly adding a fixed amount of medicine into the cold water tank, then stirring it with a stirring structure, and finally conveying it after thorough stirring. This results in a gap period, which affects the efficiency of cold water delivery.

[0006] Therefore, a dosing structure that allows for uninterrupted dosing and good mixing is needed. Utility Model Content:

[0007] The purpose of this invention is to provide a circulating water cooling system for calcium carbide production.

[0008] This utility model is implemented by the following technical solution:

[0009] A circulating water cooling system for calcium carbide production includes a dosing tank, a cold water pool, a filter, a calcium carbide furnace, a side filter, a hot water pool, and a cooling tower. A drain hopper is fixedly installed at the bottom of the dosing tank. Multiple piston plates are installed inside the dosing tank, with adjacent piston plates fixedly connected by an arc-shaped connecting rod. A dosing pipe is fixedly inserted inside the dosing tank, and a dosing hole is fixedly provided on the dosing pipe. One end of each piston plate is fitted against the outer wall of the dosing pipe. An inlet pipe is fixedly connected to one side of the dosing tank, and the inlet pipe is inclined. A U-shaped tube is fixedly connected to the outer wall of the dosing pipe, and an inlet pipe is fixedly connected to the outer wall of the dosing pipe. Two limiting rings are fixedly installed inside the dosing pipe, and a pressure plate is provided between the two limiting rings. A pressure rod is fixedly connected to the top of the pressure plate, and the top of the pressure rod extends out of the dosing pipe and is slidably connected to it. A cylinder is fixedly installed at the top of the dosing pipe, and the output end of the cylinder is fixedly connected to the top of the pressure rod.

[0010] Preferably, both the drug inlet tube and the U-tube are equipped with one-way valves.

[0011] Preferably, a cold water pool is provided below the drain hopper. The cold water pool is fixedly connected to and communicates with the filter input end through a pipeline. The filter output end is fixedly connected to and communicates with the calcium carbide furnace circulating water input end through a pipeline. The calcium carbide furnace circulating water output end is communicated with a hot water pool through a pipeline. The hot water pool output end is fixedly connected to and communicates with the cooling tower input end through a pipeline. The cooling tower output end is connected to the cold water pool through a pipeline. The filter backwash output end is fixedly connected to and communicates with the side filter input end through a pipeline. The side filter output end is connected to the cold water pool through a pipeline.

[0012] The advantages of this invention are: by utilizing the end of one stroke of the cylinder, the medicine is added to the zone. As the water continues to flow, the zone containing sufficient medicine rotates to the discharge hopper, thereby discharging into the cold water tank, achieving uninterrupted flow and ensuring the flow rate of the cold water. At the same time, each zone is filled with the corresponding medicine, replacing the traditional stirring in the cold water tank, reducing costs, and effectively improving mixing efficiency and ensuring thorough mixing.

Detailed implementation method:

[0017] like Figures 1 to 3 As shown, a circulating water cooling system for calcium carbide production includes a dosing tank 1, a cold water pool 2, a filter 3, a calcium carbide furnace 4, a side filter 5, a hot water pool 6, and a cooling tower 7. A drain hopper 8 is fixedly installed at the bottom of the dosing tank 1. Multiple piston plates 11 are installed inside the dosing tank 1, with adjacent piston plates 11 fixedly connected by an arc-shaped connecting rod 12. A dosing pipe 9 is fixedly inserted into the dosing tank 1, and a dosing hole 10 is fixedly provided on the dosing pipe 9. One end of the multiple piston plates 11 is fitted against the outer wall of the dosing pipe 9. An inlet pipe 13 is fixedly connected to one side of the dosing tank 1. 3. The dosing pipe 9 is inclined. A U-shaped tube 14 is fixedly connected to the outer wall of the dosing pipe 9. An inlet pipe 15 is fixedly connected to the outer wall of the dosing pipe 9. Two limiting rings 19 are fixedly installed inside the dosing pipe 9. A pressure plate 17 is set between the two limiting rings 19. A pressure rod 18 is fixedly connected to the top of the pressure plate 17. The top of the pressure rod 18 extends out of the dosing pipe 9 and is slidably connected to it. A cylinder 16 is fixedly installed at the top of the dosing pipe 9. The output end of the cylinder 16 is fixedly connected to the top of the pressure rod 18. When working, the liquid medicine enters the interior through the inlet pipe 15. At this time, the cylinder 16 retracts (see attached diagram). Figure 1 In this state, the pressure plate 17 allows the liquid medicine to flow into the bottom of the dosing pipe 9 through the U-shaped tube 14. Then, the cylinder 16 extends, allowing the liquid medicine to enter between the two corresponding piston plates 11 through the dosing hole 10, thus mixing with the cold water. Inside the dosing tank 1, due to the inclined inlet pipe 13, the water flow impacts the corresponding piston plate 11, causing it to rotate. When it rotates to the interval corresponding to the dosing hole 10, it is exactly the end of one stroke of the cylinder 16, thus adding the liquid medicine into this interval. With the continuous flow of water, the interval with sufficient liquid medicine rotates to the drain hopper 8, thus discharging into the cold water pool, achieving uninterrupted flow and ensuring the flow rate of the cold water. At the same time, the corresponding liquid medicine is added to each interval, replacing the traditional stirring in the cold water pool, reducing costs, and effectively improving mixing efficiency and ensuring thorough mixing.

[0018] Both the inlet pipe 15 and the U-shaped pipe 14 are equipped with one-way valves. The liquid medicine in the U-shaped pipe 14 can only flow from top to bottom, and the liquid medicine in the inlet pipe 15 can only enter the dosing pipe 9. The dosing hole 10 is also equipped with a one-way valve to ensure that the cold water does not flow back.

[0019] A cold water tank 2 is installed below the drain hopper 8. The cold water tank 2 is fixedly connected to the input end of the filter 3 through a pipeline. The output end of the filter 3 is fixedly connected to the circulating water input end of the calcium carbide furnace 4 through a pipeline. The circulating water output end of the calcium carbide furnace 4 is connected to the hot water tank 6 through a pipeline. The output end of the hot water tank 6 is fixedly connected to the input end of the cooling tower 7 through a pipeline. The output end of the cooling tower 7 is connected to the cold water tank 2 through a pipeline. The backwash output end of the filter 3 is fixedly connected to the input end of the bypass filter 5 through a pipeline. The output end of the bypass filter 5 is connected to the cold water tank 2 through a pipeline.
