Description

Technical Field

[0001] The utility model relates to the field of heaters, in particular to a molten salt heater. Background Art

[0002] A molten salt heater, also known as a nitrate furnace or saltpeter tank, is a heating device that utilizes special tubular electric heating elements in a flanged cluster with a pressure vessel to form a complete heating system. It primarily heats nitrate as a heating medium, thereby heating other substances.

[0003] The working principle of the molten salt heater is relatively simple and efficient: when nitrate salt at room temperature is poured into the molten salt tank, it is preheated by the electric heating element in the molten salt tank to make it liquid. The liquid molten salt is then pumped out by the molten salt pump and flows into the heating tube. When it reaches the outlet of the molten salt heater, the molten salt has basically been heated and then transfers the heat to the substance that needs to be heated.

[0004] Existing molten salt heaters heat the outside through heating tubes when in use. During use and observation, it was found that after use, the surface of the heating tube will still remain high temperature and it is difficult to cool down quickly. This will cause the heating tube to be in a high temperature environment for a long time and age quickly, thereby shortening the service life of the heating tube.

[0005] Therefore, a molten salt heater is proposed to address the above problems. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a molten salt heater described in the present invention comprises a support seat; a molten salt heater body is installed on the top of the support seat; a plurality of heating tubes are installed on the inner side wall of the molten salt heater body; a cooling tube is provided through the end of the molten salt heater body and is slidably connected; a water pump is fixedly connected to the end of the cooling tube; a cooling box is fixedly connected to the water pump and the cooling box is connected by a pipe; a cooling tube is fixedly connected to the inner side wall of the cooling tube; the heating tube is located inside the cooling tube; the water pump and the cooling tube are connected by a pipe; the cooling tube and the cooling box are in a communicating relationship; the cooling tube is pushed so that the coolant in the cooling tube can cool the heating tube, thereby realizing rapid cooling of the heating tube by the device, reducing aging of the heating tube due to long-term high-temperature operation, and extending the service life of the heating tube.

[0008] Preferably, a fixed plate is fixed to the middle of the molten salt heater body; a plurality of convex plates are fixed to the middle of the cooling cylinder; a sliding rod is fixed to the middle of the convex plate; the sliding rod and the fixed plate are arranged through and are slidably connected; through the cooperation of the fixed plate and the sliding rod, the cooling cylinder will be subjected to the force exerted by the fixed plate when it moves, thereby improving the stability of the cooling cylinder when it moves and reducing the shaking that occurs when the cooling cylinder moves.

[0009] Preferably, a plurality of top plates are fixed to the top of the support seat; the top plates are located at the bottom of the cooling tube; the ends of the top plates are arc-shaped structures; when the molten salt heater body is used for too long, the ends of the cooling tube will deviate toward the support seat due to gravity, and the top plates will come into contact with the cooling tube and provide additional support to the surface of the cooling tube, thereby improving the stability of the connection between the cooling tube and the molten salt heater body and reducing the deformation of the ends of the cooling tube due to gravity.

[0010] Preferably, a plurality of pull ropes are symmetrically fixed to the top of the top plate; scrapers are fixed between adjacent pull ropes; the cooling cylinder is located inside the scraper; when the staff pushes the cooling cylinder, the cooling cylinder will pass through the scraper and rub against it, and the scraper will clean the surface of the cooling cylinder when it contacts the cooling cylinder, reducing impurities attached to the surface of the cooling cylinder and improving the smoothness of the sliding of the cooling cylinder. At the same time, the scraper will transfer the friction of the cooling cylinder to the pull rope, causing the pull rope to shake, so that the scraper will shake along the surface of the cooling cylinder, enhancing the cleaning effect of the scraper on the cooling cylinder.

[0011] Preferably, a plurality of pressure plates are fixedly connected to the middle part of the slide rod; the pressure plates are staggered; the pressure plates and scrapers are correspondingly arranged; when the cooling cylinder moves, it moves with the slide rod, and when the slide rod moves, it moves with the pressure plates. Because the pressure plates are staggered, when the pressure plates move, they come into contact with and squeeze the scrapers, causing the scrapers to swing more violently under the squeezing action of the pressure plates, further enhancing the cleaning effect of the scrapers on the cooling cylinder.

[0012] Preferably, a cleaning box is fixedly connected to the inner side wall of the scraper; a plurality of sponges are fixedly connected to the inner side wall of the cleaning box; when the scraper comes into contact with the cooling cylinder, the sponge will also come into contact with the cooling cylinder, and cleaning liquid will be injected into the cleaning box, which will penetrate into the sponge and make it moist. The sponge will clean the surface of the cooling cylinder, further improving the cleanliness of the surface of the cooling cylinder.

[0013] Preferably, the inner side wall of the top plate is rotatably connected to a plurality of ball bearings; the ball bearings are arranged in a circular array; when the cooling cylinder contacts the top plate, it also contacts the ball bearings, and when the cooling cylinder moves, the ball bearings rotate under the action of friction, thereby reducing the jamming of the cooling cylinder when it slides along the top plate and reducing the friction between the cooling cylinder and the top plate.

After the molten salt heater body 12 is used up, the surface of the heating tube 17 will still be warm. At this time, the water pump 14 can be started to make the coolant in the cooling box 15 enter the cooling tube 16 through the pipeline, and then the cooling cylinder 13 can be pushed to make the cooling cylinder 13 slide along the molten salt heater body 12, and the molten salt heater body 12 will move with the cooling tube 16. When the cooling tube 16 moves, it will pass through the heating tube 17. When the coolant flows in the cooling tube 16, it will cool the heating tube 17 by heat conduction, and then the coolant will flow back into the cooling box 15 through the cooling tube 16 until the heating tube 17 is cooled. Finally, the cooling cylinder 13 can be pulled out again and the water pump 14 can be turned off; pushing the cooling cylinder 13 allows the coolant in the cooling tube 16 to cool the heating tube 17, thereby realizing rapid cooling of the heating tube 17 by the device, reducing aging of the heating tube 17 caused by long-term high-temperature operation, and extending the service life of the heating tube 17.

[0027] See also Figures 2 to 5 As shown, a fixed plate 2 is fixed to the middle of the molten salt heater body 12; a plurality of convex plates 22 are fixed to the middle of the cooling cylinder 13; a sliding rod 23 is fixed to the middle of the convex plate 22; the sliding rod 23 and the fixed plate 2 are arranged through and are slidably connected; when the cooling cylinder 13 moves, it will move with the convex plate 22 and the sliding rod 23, and when the sliding rod 23 moves, it will slide along the surface of the fixed plate 2, and when the sliding rod 23 moves, it will be subject to the force applied by the fixed plate 2, so that the cooling cylinder 13 will be subject to additional limiting effect when it moves; through the cooperation of the fixed plate 2 and the sliding rod 23, when the cooling cylinder 13 moves, it will be subject to the force applied by the fixed plate 2, thereby improving the stability of the cooling cylinder 13 when it moves and reducing the shaking that occurs when the cooling cylinder 13 moves.

[0028] See also Figure 3 As shown, a plurality of top plates 3 are fixed to the top of the support seat 1; the top plates 3 are located at the bottom of the cooling cylinder 13; the ends of the top plates 3 are arc-shaped structures; when the molten salt heater body 12 is used for too long, the ends of the cooling cylinder 13 will be offset toward the support seat 1 due to gravity, and the top plates 3 will come into contact with the cooling cylinder 13 and provide additional support for the surface of the cooling cylinder 13, thereby improving the stability of the connection between the cooling cylinder 13 and the molten salt heater body 12 and reducing the deformation of the ends of the cooling cylinder 13 due to gravity.

[0029] See also Figure 3 and Figure 4 As shown, a plurality of pull ropes 4 are symmetrically fixed to the top of the top plate 3; scrapers 42 are fixed between adjacent pull ropes 4; the cooling cylinder 13 is located inside the scraper 42; when the staff pushes the cooling cylinder 13, the cooling cylinder 13 will pass through the scraper 42 and rub against it. When the scraper 42 contacts the cooling cylinder 13, its surface will be cleaned, thereby reducing impurities attached to the surface of the cooling cylinder 13 and improving the smoothness of the sliding of the cooling cylinder 13. At the same time, the scraper 42 will transfer the friction of the cooling cylinder 13 to the pull rope 4, causing the pull rope 4 to shake, so that the scraper 42 will shake along the surface of the cooling cylinder 13, thereby enhancing the cleaning effect of the scraper 42 on the cooling cylinder 13.

[0030] See also Figure 5 As shown, a plurality of pressure plates 5 are fixedly connected to the middle part of the slide bar 23; the pressure plates 5 are staggered; the pressure plates 5 and the scrapers 42 are correspondingly arranged; when the cooling cylinder 13 moves, it will move with the slide bar 23, and when the slide bar 23 moves, it will move with the pressure plates 5. Because the pressure plates 5 are staggered, when the pressure plates 5 move, they will come into contact with and squeeze the scrapers 42, so that the scrapers 42 will swing more violently under the squeezing action of the pressure plates 5, further enhancing the cleaning effect of the scrapers 42 on the cooling cylinder 13.

[0031] See also Figure 4 As shown, the inner wall of the scraper 42 is fixedly connected to a cleaning box 6; the inner wall of the cleaning box 6 is fixedly connected to a plurality of sponges 62; when the scraper 42 comes into contact with the cooling cylinder 13, the sponge 62 will also come into contact with the cooling cylinder 13, and the cleaning box 6 is injected with cleaning liquid, which will penetrate into the sponge 62 to make it wet, and the sponge 62 will clean the surface of the cooling cylinder 13, further improving the cleanliness of the surface of the cooling cylinder 13.

[0033] Working principle: Pour the molten salt into the molten salt heater body 12 through the feed port of the molten salt heater body 12, and then the molten salt heater body 12 will start and heat the molten salt. The heated molten salt will then enter the heating tube 17 and release heat. After the molten salt heater body 12 is used up, the surface of the heating tube 17 will still be warm. At this time, the water pump 14 can be started so that the coolant in the cooling box 15 will enter the cooling tube 16 through the pipe. Then, the cooling tube 13 can be pushed so that the cooling tube 13 slides along the molten salt heater body 12. The molten salt heater body 12 will move with the cooling tube 16, and the cooling tube 16 will pass through the heating tube 17 when it moves. When the coolant flows in the cooling pipe 16, the heating pipe 17 is cooled by heat conduction, and then the coolant flows back into the cooling box 15 through the cooling pipe 16 until the heating pipe 17 is cooled. Finally, the cooling cylinder 13 can be pulled out again and the water pump 14 can be turned off. When the cooling cylinder 13 moves, it will move with the convex plate 22 and the sliding rod 23. When the sliding rod 23 moves, it will slide along the surface of the fixed plate 2. When the sliding rod 23 moves, it will be subject to the force applied by the fixed plate 2, so that the cooling cylinder 13 will be subject to additional limiting effect when it moves. When the molten salt heater body 12 is used for too long, the end of the cooling cylinder 13 will deviate toward the support seat 1 due to gravity, and the top plate 3 When the cooling cylinder 13 is in contact with the scraper 42, the scraper 42 will clean the surface of the cooling cylinder 13, reduce the impurities attached to the surface of the cooling cylinder 13, and improve the smoothness of the sliding of the cooling cylinder 13. At the same time, the scraper 42 will transfer the friction of the cooling cylinder 13 to the pull rope 4, causing the pull rope 4 to shake, so that the scraper 42 will shake along the surface of the cooling cylinder 13; when the cooling cylinder 13 moves, it will move with the slide bar 23, and the slide bar 23 will move. The pressure plate 5 moves together with the pressure plate 5. Because the pressure plate 5 is staggered, the pressure plate 5 will come into contact with the scraper 42 and squeeze it when it moves, so that the scraper 42 will swing more violently under the squeezing action of the pressure plate 5; when the scraper 42 comes into contact with the cooling cylinder 13, the sponge 62 will also come into contact with the cooling cylinder 13. Cleaning liquid is injected into the cleaning box 6, and the cleaning liquid will penetrate into the sponge 62 to make it wet, and the sponge 62 will clean the surface of the cooling cylinder 13; when the cooling cylinder 13 comes into contact with the top plate 3, it will also come into contact with the ball 7. When the cooling cylinder 13 moves, the ball 7 will rotate under the action of friction, reducing the jamming of the cooling cylinder 13 when sliding along the top plate 3.
