Description

Technical Field

[0001] This solution belongs to the field of caustic soda flake machines, specifically involving a caustic soda flake machine with the function of reducing caustic soda crystallization. Background Technology

[0002] In the production of caustic soda flakes (solid sodium hydroxide), the process of evaporating and concentrating the alkali solution followed by cooling and crystallization is typically employed. Traditional caustic soda flake machines use a rotating drum (roller) in an alkali solution tank, causing the alkali solution to form a thin film on the surface of the drum, which then solidifies into flakes after cooling.

[0003] A search revealed a novel caustic soda flake machine in utility model patent CN206580567U. The hopper is equipped with a fan for cooling the caustic soda flakes. The drum has a jacket containing a circulating cooling water pipe connected to an inlet and outlet pipe, improving cooling efficiency and facilitating long-term operation. The arc-shaped pot contains a heating element connected to an electronic controller.

[0004] However, when the caustic soda flake machine is first started, the equipment temperature is low. If the cooling water flow rate is too high or the cooling water temperature is too low, low-temperature crystalline alkali will appear on the surface of the drum of the caustic soda flake machine, which is difficult for the scraper to remove. At the same time, the cooling water utilization rate is low, which can easily lead to the waste of water resources. Utility Model Content

[0005] The purpose of this solution is to provide a caustic soda flake machine with the function of reducing caustic soda crystallization, so as to solve the problem of caustic soda crystallization caused by excessively low cooling water temperature in the caustic soda flake machine, and at the same time solve the problem of low cooling water utilization rate, which easily leads to water waste.

[0006] To achieve the above objectives, this solution provides a caustic soda flake machine with the function of reducing caustic soda crystallization, including an caustic soda tank. Two bearing seats are fixedly connected to the top of the caustic soda tank. A rotating pipe is installed inside each bearing seat through a bearing. A rotating drum is fixedly connected between the two rotating pipes, and the rotating drum and the rotating pipe are connected in communication. A manifold box is provided above the rotating drum. Cooling pipes are fixedly connected to the left and right sides of the manifold box. The cooling pipes pass through the rotating pipes and the rotating drum and are connected to the rotating pipes through a sealed bearing. A water pump is fixedly installed at the bottom inner side of the manifold box. The output end of the water pump is connected to the cooling pipe. An electric heating rod and a temperature sensor are provided at the top inner side of the manifold box. The electric heating rod and the temperature sensor are electrically connected.

[0007] The principle of this solution is as follows: First, remove the rubber stopper. Then, fill the manifold with cooling water and circulate it through the cooling pipes via a water pump. The motor, through the engagement of drive and driven gears, drives the rotating pipe and drum. Cooling water continuously sprays the drum through vertical pipes, horizontal pipes, and nozzles, lowering its temperature. This causes the alkaline solution in the alkaline tank to condense on the surface of the drum, which can then be scraped off using an external scraper. When the cooling water temperature is too low, an electric heating rod heats the water, preventing excessive crystallization of the alkaline solution on the drum surface due to low temperature, making it easier to scrape off. Additionally, cooling water accumulates at the bottom of the drum, at which point a second water pump re-pumps it back into the manifold through a circulation pipe, achieving water reuse and reducing water waste.

[0008] The technical advantage of this solution is that by installing an electric heating rod and a temperature sensor in the manifold for storing cooling water, when the cooling water temperature is too low, the electric heating rod heats the cooling water, inhibiting excessive crystallization of the alkali solution on the surface of the drum due to low temperature, making it easier for the scraper to remove it.

[0009] Through a closed-loop system consisting of a retaining ring, a circulation pipe, and a water pump, the cooling water inside the drum can be recycled back to the manifold through the ring groove and through holes, realizing the reuse of cooling water and reducing water waste.

[0010] Furthermore, a vertical pipe is connected to a section of the cooling pipe inside the drum, and a horizontal pipe is connected to the end of the vertical pipe. Multiple nozzles are installed on the horizontal pipe. Cooling water flowing inside the cooling pipe can be discharged through the vertical pipe, horizontal pipe, and nozzles, thus cooling the drum.

[0011] Furthermore, a driven gear is fixedly connected to the outside of the rotating tube on the left side, and a motor is fixedly installed on the left side of the alkaline water tank. A drive gear is fixedly connected to the end of the output shaft of the motor, and the drive gear meshes with the driven gear. The rotating tube and the drum can be rotated through the transmission of the motor and the gear.

[0012] Furthermore, a retaining ring is rotatably connected to the right side of the drum, and a circulation pipe is fixedly connected inside the retaining ring, with the circulation pipe penetrating the retaining ring. The circulation pipe is connected to a manifold box, and a second water pump is fixedly installed at the bottom inner side of the manifold box. The input end of the second water pump is fixedly connected to the circulation pipe. Cooling water inside the drum can be reintroduced into the manifold box through the circulation pipe and the second water pump.

[0013] Furthermore, two sealing rings are embedded on the side of the retaining ring closest to the drum, and these sealing rings abut against the drum. The sealing rings enhance the seal between the retaining ring and the drum.

[0014] Furthermore, an annular groove and a through hole are provided on the right side of the drum, and the annular groove and the through hole are connected. The positions of the annular groove and the through hole correspond to the positions of the retaining ring. Cooling water inside the drum flows into the annular groove through the through hole and enters the circulation pipe.

[0015] Furthermore, a rubber stopper is slidably connected to the top of the manifold, and a pull ring is fixedly connected to the top of the rubber stopper. After removing the rubber stopper, cooling water can be added to the manifold. Attached Figure Description

Detailed Implementation

[0019] The basic implementation examples are as follows: Figures 1-3 The diagram shows a caustic soda flake machine with a function of reducing caustic soda crystallization. It includes an caustic soda tank 1, with two bearing seats 2 fixedly connected to the top of the tank. Each bearing seat 2 has a rotating pipe 3 mounted inside via bearings. A rotating drum 4 is fixedly connected between the two rotating pipes 3, and the drum 4 is connected to the rotating pipes 3. A cooling pipe 5 is located inside the drum 4, with a vertical pipe 51 connected to one end. A horizontal pipe 52 is connected to the other end of the vertical pipe 51, and multiple nozzles 53 are installed on the horizontal pipe 52. Cooling water flowing in the cooling pipe 5 can be discharged through the vertical pipe 51, horizontal pipe 52, and nozzles 53, thus cooling the drum 4. A driven gear 18 is fixedly connected to the outside of the left rotating pipe 3. A motor 19 is fixedly installed on the left side of the caustic soda tank 1, and a drive gear 20 is fixedly connected to the end of the output shaft of the motor 19. The drive gear 20 meshes with the driven gear 18. The rotating pipe 3 and the drum 4 can rotate through the transmission of the motor 19 and the gears.

[0020] like Figure 3 As shown, a manifold 6 is installed above the drum 4. A rubber stopper 10 is slidably connected to the top of the manifold 6, and a pull ring 11 is fixedly connected to the top of the rubber stopper 10. After removing the rubber stopper 10, cooling water can be added to the manifold 6. Cooling pipes 5 are fixedly connected to both the left and right sides of the manifold 6. The cooling pipes 5 pass through the rotating pipe 3 and the drum 4 and are connected to the rotating pipe 3 through a sealed bearing. A water pump 7 is fixedly installed at the bottom inner side of the manifold 6. The output end of the water pump 7 is connected to the cooling pipe 5. An electric heating rod 8 and a temperature sensor 9 are installed at the top inner side of the manifold 6. The electric heating rod 8 and the temperature sensor 9 are electrically connected.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a retaining ring 12 is rotatably connected to the right side of the drum 4. A circulation pipe 13 is fixedly connected inside the retaining ring 12, and the circulation pipe 13 passes through the retaining ring 12. The circulation pipe 13 connects to the manifold 6, and a second water pump 14 is fixedly installed at the bottom inner side of the manifold 6. The input end of the second water pump 14 is fixedly connected to the circulation pipe 13. The cooling water in the drum 4 can be reintroduced into the manifold 6 through the circulation pipe 13 and the second water pump 14. Two sealing rings 15 are embedded on the side of the retaining ring 12 near the drum 4, and the sealing rings 15 abut against the drum 4. The sealing rings 15 increase the sealing between the retaining ring 12 and the drum 4. An annular groove 16 and a through hole 17 are provided on the right side of the drum 4. The annular groove 16 and the through hole 17 are connected, and their positions correspond to the positions of the retaining ring 12. The cooling water in the drum 4 flows into the annular groove 16 through the through hole 17 and enters the circulation pipe 13.

[0022] The specific implementation process of this utility model is as follows: In use, first remove the rubber stopper 10, then fill the manifold 6 with cooling water, and circulate it in the cooling pipe 5 through the water pump 7. Then, the motor 19 can drive the rotating pipe 3 and the rotating drum 4 to rotate through the cooperation of the drive gear 20 and the driven gear 18. The cooling water continuously sprays the rotating drum 4 through the vertical pipe 51, the horizontal pipe 52 and the nozzle 53 to lower its temperature. In this way, the alkaline water in the alkaline water tank 1 will condense on the surface of the rotating drum 4, and then it can be scraped off with an external scraper. When the temperature of the cooling water is too low, the electric heating rod 8 heats the cooling water to prevent the alkaline solution from crystallizing excessively on the surface of the rotating drum 4 due to the low temperature, making it easier to scrape off with the scraper. In addition, the cooling water will accumulate at the bottom of the rotating drum 4. At this time, the water pump 14 will pump it back into the manifold 6 through the circulation pipe 13 to realize the reuse of cooling water and reduce water waste.

[0023] This solution involves installing an electric heating rod 8 and a temperature sensor 9 inside the manifold 6 for cooling water storage. When the cooling water temperature is too low, the electric heating rod 8 heats the cooling water, preventing excessive crystallization of the alkaline solution on the surface of the drum 4 due to low temperature, making it easier for the scraper to remove it. Through a closed-loop system consisting of a retaining ring 12, a circulation pipe 13, and a second water pump 14, the cooling water in the drum 4 can be recycled back to the manifold 6 via the ring groove 16 and the through hole 17, realizing the reuse of cooling water and reducing water waste.
