Description

Technical Field

[0001] The utility model relates to the technical field of cooling water circulation components for cadmium vertical pulling furnaces, in particular to cooling water circulation components for cadmium vertical pulling furnaces. Background Art

[0002] Cadmium occurs naturally with zinc; it is an excellent neutron-absorbing metal, made into rods that slow down chain fission reactions in nuclear reactors, and is useful in zinc-cadmium batteries; its brightly colored sulfide is used to make cadmium yellow pigment.

[0003] In the process of producing and processing cadmium by the vertical pulling method, a vertical pulling furnace is required to melt and shape it. The brief process is to first load the raw materials into the quartz crucible in the furnace, seal the furnace body and introduce protective gas, heat the material block to melt through the heater, and then process and shape it, and finally turn off the heater to stop the furnace; because the melting process is in a high temperature state, in order to meet the requirements of high temperature resistance, strength, purity, etc., the thermal field components such as heaters, crucible sides, support rods, insulation cylinders, heat shields, etc. are generally made of isostatic graphite, and at the same time, in order to avoid high temperature damage to the equipment and reduce the power consumption of crystal pulling, insulation felt made of graphite fiber is generally used to wrap the graphite insulation cylinder to isolate the heat, but these two The material easily reacts with oxygen in the air at high temperature. For graphite parts, the silicon carbide layer produced by oxidation and the graphite layer expand differently during the cooling process, which can easily cause rupture. For graphite felt, it can cause fiber shortening, increased voids, reduced thickness, and weakened thermal insulation effect. Therefore, the vertical pulling furnace needs to maintain a longer shutdown time in a closed state to cool the hot field. Generally, water cooling is used to accelerate the cooling. At present, the water cooling pipes in most water-cooling circulation equipment are fixed. If you want to cool the outside of the vertical pulling furnace, you need to set up more water cooling pipes, which is more troublesome.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The cooling water circulation component of the cadmium vertical pulling furnace includes a rotating contact water cooling mechanism, a water temperature cooling mechanism and an automatic rotating mechanism. The rotating contact water cooling mechanism includes a water cooling box 1. The lower side of the water cooling box 1 is fixedly connected with a connecting plate 2, and the lower side of the connecting plate 2 is fixedly connected with an adjusting frame 3. The bottom of the water cooling box 1 is fixedly installed with a first water pump 4, and the output end of the first water pump 4 is fixedly connected with a first flexible bellows 5. The lower side of the first flexible bellows 5 is fixedly connected with a water cooling pipe 6, and one end of the water cooling pipe 6 is fixedly connected with a second flexible bellows 7. The bottom of the water cooling box 1 is fixedly installed with a second water pump 8, and the output end of the second water pump 8 is fixedly connected to the second flexible bellows 7. A slide groove 9 is opened inside the adjusting frame 3, and a slider 10 is arranged inside the slide groove 9. The interior of the slide groove 9 is fixedly connected with a fixed plate 11. A pressure sensor 12 is fixedly installed inside the fixed plate 11, the slider 10 is slidably connected to the slide groove 9, and the water-cooling pipe 6 is arranged inside the slider 10 and fixedly connected to the slider 10, so that the water-cooling pipe 6 is fitted to the outside of the cadmium vertical pulling furnace, thereby cooling the cadmium vertical pulling furnace. The slider 10 can be slid in the slide groove 9 by setting the automatic rotation mechanism, so that the water-cooling pipe 6 rotates to cool the outside of the cadmium vertical pulling furnace. When the slider 10 touches the pressure sensor 12, the automatic rotation mechanism will automatically rotate in the opposite direction, and rotate forward when it touches the pressure sensor 12 again. This can be repeated to perform a large-area water-cooling cooling treatment on the outside of the cadmium vertical pulling furnace, so that only two water-cooling pipes 6 are needed to cool the cadmium vertical pulling furnace, making it more convenient and simple to use.

[0021] In one aspect of the present embodiment, after the water-cooling tube 6 contacts the outside of the cadmium vertical pulling furnace, the start motor 13 drives the turntable 14 to rotate in the limit groove 16. When the turntable 14 rotates, the slider 10 is driven to slide in the slide groove 9 through the connecting frame 15, thereby driving the water-cooling tube 6 to move and water-cooling the outside of the cadmium vertical pulling furnace. The first flexible bellows 5 and the second flexible bellows 7 are arranged so that the length of the extension of the first flexible bellows 5 and the second flexible bellows 7 can be used for the slider 10 to move in a semicircle in the slide groove 9. The slider 10 moves in the slide groove 9. After moving inwardly in a semicircle, it will touch the pressure sensor 12, and the pressure sensor 12 is electrically connected to the motor 13. After receiving the signal from the pressure sensor 12, the motor 13 will rotate in the opposite direction, thereby driving the slider 10 to move in the opposite semicircle in the slide groove 9. After contacting the pressure sensor 12 again, the motor 13 continues to adjust the direction. This repetition can make the water-cooling tube 6 contact the surface of the cadmium vertical pulling furnace over a large area, thereby cooling the cadmium vertical pulling furnace. The motor 13 can be protected by an external protection device during use.

[0022] In one aspect of this embodiment, after pouring water into the water cooling box 1, the refrigerator 17 is started, and the cold air of the refrigerator 17 is transmitted to the conduction rod 18. The conduction rod 18 is arranged in the water cooling box 1, so that the conduction rod 18 conducts the temperature to the water in the water cooling box 1, and the water in the water cooling box 1 can be cooled.

[0023] In one aspect of the present embodiment, during the use of the water-cooling box 1, the threaded ring 19 is screwed into the water-cooling box 1, and the closing cover 20 can be fixed on the upper side of the water-cooling box 1 to seal the water-cooling box 1. The provision of the rubber ring 21 can increase the degree of sealing between the closing cover 20 and the water-cooling box 1 to prevent water in the water-cooling box 1 from leaking out. At the same time, when the water-cooling box 1 needs to be cleaned, the user can hold the handle 25 in the mounting groove 24, rotate the closing cover 20 to screw the threaded ring 19 out of the water-cooling box 1, so that the interior of the water-cooling box 1 is exposed, thereby facilitating the cleaning of the interior of the water-cooling box 1. When it is necessary to store water in the water-cooling box 1, the pipe cover 23 is unscrewed so that external water can be stored in the water-cooling box 1 through the delivery pipe 22.

[0024] The working principle of the utility model: when the cooling water circulation component of the cadmium vertical pulling furnace is used, the device is first fixed at the upper side or lower side of the cadmium vertical pulling furnace, so that the water-cooling pipe 6 contacts the cadmium vertical pulling furnace, the refrigerator 17 is started, and the water in the water-cooling box 1 is cooled through the conductive rod 18, and then the first water pump 4 is started to transport the water in the water-cooling box 1 to the water-cooling pipe 6 through the first flexible bellows 5. After the water circulates in the water-cooling pipe 6, the second water pump 8 is started to pump the water in the water-cooling pipe 6 back to the water-cooling box 1 through the second flexible bellows 7, and at the same time, the motor 13 is started to drive the turntable 14 to rotate, and the rotation of the turntable 14 drives the slider 10 to slide in the slide groove 9 through the connecting frame 15, thereby driving the water-cooling pipe 6 to move on the outside of the cadmium vertical pulling furnace Water cooling treatment, through the arrangement of the first flexible bellows 5 and the second flexible bellows 7, the extended length of the first flexible bellows 5 and the second flexible bellows 7 can allow the slider 10 to move in a semicircle in the slide groove 9. After the slider 10 moves in a semicircle in the slide groove 9, it will touch the pressure sensor 12. The pressure sensor 12 is electrically connected to the motor 13. After receiving the signal from the pressure sensor 12, the motor 13 will rotate in the opposite direction, thereby driving the slider 10 to move in the opposite semicircle in the slide groove 9. After contacting the pressure sensor 12 again, the motor 13 continues to adjust the direction. This repetition can make the water-cooled tube 6 contact the surface of the cadmium vertical pulling furnace over a large area, so as to cool the cadmium vertical pulling furnace. In this scheme, all electrical equipment are powered by an external power supply.
