Technical Field
[0001] The invention relates to the technical field of mixed dissolution of soluble substances, in particular to a device for heating soluble substances by using a steam ejector. Background Art
[0002] The device that uses a steam ejector to heat soluble substances is an efficient, fast and energy-saving device, which is particularly suitable for the solution preparation process in chemical production. For example, in the preparation process of ammonium nitrate solution, the steam ejector can directly inject high-temperature steam into the dissolution container to quickly increase the temperature of the solution. According to the solubility characteristics of ammonium nitrate, its solubility increases with increasing temperature. In addition, heating enhances the thermal motion of solute molecules and solvent molecules, thereby promoting the destruction of the interaction force between ions and allowing more ammonium nitrate molecules to dissolve in water.
[0003] This processing and dissolution process usually takes place in a dissolution tank. While using a steam ejector to accelerate the dissolution of the solute, the rotation of the stirring rod is also used to further improve the dissolution efficiency. The rotation of the stirring rod can increase the contact area between the solute and the solvent, thereby increasing the dissolution rate. However, during the stirring of the stirring rod and the operation of the steam ejector, part of the solution will splash and adhere to the inner wall of the dissolution tank. The ammonium nitrate solution adheres to the inner wall of the dissolution tank to form solid particles, which will not drip back into the solution, resulting in material waste and substandard solution concentration.

At the same time, the motor of the rotating drum 4 is started, and the rotation of the rotating drum 4 drives the rotating rod 5 and the stirring rod 6 to rotate. The rotation of the stirring rod 6 can further improve the dissolution quality of the ammonium nitrate solution. However, during the rotation of the stirring rod 6 and the operation of the steam ejector 2, a part of the solution will splash onto the inner wall of the dissolving tank 3 to form fixed particles. At this time, the scraper 7 can be driven by the scraper assembly 8 to move downward along the inner wall of the dissolving tank 3 so that the scraper 7 can scrape the solid particles or solution attached to the inner wall back into the solution, so as to ensure that the concentration of the solution is not affected. The base 1 provides a support for the dissolving tank 3.
[0027] See also Figure 2 , Figure 4 and Figure 6As shown, in the present embodiment, preferably, the scraper assembly 8 comprises a movable block 81, and vertical grooves 301 are axially symmetrically provided on both sides of the dissolving tank 3, the movable block 81 is slidably connected with the vertical grooves 301, and a return spring 82 is fixedly arranged between the bottom of the movable block 81 and the bottom of the vertical groove 301, and a limiting rod 83 is fixedly arranged on one side of the movable block 81, and the limiting rod 83 moves through the scraper 7 away from one end of the movable block 81; when it is necessary to scrape off the solid particles attached to the inner wall of the dissolving tank 3, the movable block 81 is moved downward along the vertical groove 301, and the movable block 81 moves downward to drive the limiting rod 83 and the scraper 7 to move downward synchronously, and the scraper 7 fits with the inner wall of the dissolving tank 3 during the downward movement, so that the solid particles attached to the dissolving tank 3 can be scraped off, and the movable block 81 will compress the return spring 82 during the downward movement, and the return spring 82 provides stability for the movement of the movable block 81 in the vertical groove 301.

One end of the movable rod 17 is fixedly connected to the moving block 13, and a positioning spring 18 is fixedly arranged between the moving block 13 and the positioning block 16. The positioning spring 18 is movably sleeved on the outside of the movable rod 17; the scraper 7 will move toward the middle position of the dissolving tank 3 relative to the limit rod 83 during the upward movement, and the sliding block 15 moves downward along the fixed block 12 during the movement. The movement will drive the positioning block 16 to move, and the movement of the positioning block 16 will drive the movable rod 17, the positioning spring 18 and the moving block 13 to move synchronously. In the initial state, the moving block 13 will exceed a portion of the sliding block 15. When the sliding block 15 is about to slide to the end along the fixed block 12, the moving block 13 is blocked and prevented from continuing to move. The sliding block 15 continues to move.

[0036] The working principle of the present invention is: the prepared ammonium nitrate is crushed and then added into the dissolving tank 3, and a solvent is added to dissolve the ammonium nitrate. The solvent needs to cover the steam injector 2, and then the steam injector 2 is started. One end of the steam injector 2 is connected to the steam source through a steam pipe. The steam transported by the steam pipe is sprayed into the dissolving tank 3 to dissolve the ammonium nitrate inside. At the same time, the motor of the rotating drum 4 is started. The rotation of the rotating drum 4 can drive the cylinder 29 to rotate together. The rotation of the cylinder 29 will drive the curved groove 291 to rotate, so that the limit rods 83 on both sides move up and down reciprocatingly. The up and down reciprocating movement of the limit rod 83 will drive the movable block 81 and the vertical groove 301 to move. The rotation of the rotating drum 4 will also drive the rotating rod 5 and the stirring rod 6 to move. The second bevel gear 32 is driven to rotate synchronously with the first bevel gear 31 arranged on the outer side of the fixed column 30 during the rotation of the rotating rod 5, so that the rotating rod 5 can also rotate while it revolves, and the rotation of the rotating rod 5 can drive the stirring rod 6 to rotate, which can further improve the dissolving effect. At the same time, the movable block 81 moves downward to drive the limit rod 83, the scraper 7 and the moving frame 9 to move downward synchronously, and the moving frame 9 moves up and down along the moving groove 302. Before the moving frame 9 moves downward with the scraper 7, the scraper 7 is located in the middle of the dissolving tank 3. The moving frame 9 moves downward to drive the positioning rod 10 to move downward. During the downward movement of the positioning rod 10, it will abut against the positioning groove 111 provided on the positioning plate 11. The positioning groove 111 is composed of a groove inclined at one end and a straight groove The positioning rod 10 first moves downward along the inclined groove, thereby causing the movable frame 9 to move toward the outside of the dissolving tank 3, causing the scraper 7 to move from the middle position to the edge, and finally fit with the inner wall of the dissolving tank 3, and then continues to move downward, so that the solid particles on the inner wall of the dissolving tank 3 can be scraped off during the downward movement of the scraper 7. After the scraper 7 descends, it will move upward again, and the positioning rod 10 will first move along the straight groove section of the positioning groove 111, and then contact with the inclined groove to cause the movable frame 9 to move toward the inside of the dissolving tank 3, so that the scraper 7 can move toward the middle position of the dissolving tank 3 along the limiting rod 83, and the solid particles adhered to the scraper 7 can be driven to the middle position. When the scraper 7 moves toward the middle of the dissolving tank 3 relative to the limiting rod 83, it will drive the cross plate 23 and the screw rod 24 and the rotating gear 25 move synchronously together. During the movement, the rotating gear 25 will mesh with the driving rack 28 to drive the rotating gear 25 to rotate. The rotation of the rotating gear 25 will drive the screw rod 24 to rotate, thereby driving the lifting block 26 to move downward and then driving the connecting rod 27 and the positioning block 16 to move downward. During the downward movement of the positioning block 16, the sliding block 15, the moving block 13 and other components will be driven to move downward synchronously. The abutment block 19 will first abut against the inclined groove 211 provided on the rotating plate 21 to lift the rotating plate 21 upward, and the moving block 13 can continue to move until the abutment block 19 is engaged with the clamping block 22. At this time, the movement of the sliding block 15 cannot drive the moving block 13 to move together, and the sliding block 15 is still moving. During this process, the positioning spring 18 will be compressed.The sliding block 15 continues to move until the notch 161 of the positioning block 16 abuts against the inclined groove 211 of the rotating plate 21, which drives the rotating plate 21 to continue to lift upward, so that the clamping block 22 and the abutting block 19 are released from the clamping state. Since the clamping effect of the clamping block 22 is lost, the moving block 13 and the push plate 14 will move quickly to the bottom of the scraper 7 under the action of the positioning spring 18, and the solid particles attached to the bottom of the scraper 7 can be pushed into the solution.
