Description

Technical Field

[0001] This invention relates to the field of evaporation, and more particularly to an evaporation apparatus for the production of refined industrial salt. Background Technology

[0002] Evaporation crystallization refers to the process of separating the solvent from the solute in a solution by raising the temperature, allowing the solute to polymerize and become crystals. Industrial salt is one of the most basic raw materials in the chemical industry. When refining industrial salt, it is usually processed by evaporation equipment to carry out evaporation crystallization.

[0003] A search revealed Chinese patent application CN217367222U, which discloses an evaporation and crystallization device for producing high-quality industrial salt. The device includes a tank, a discharge box, and a reaction box. The discharge box is installed through the outer wall of the tank, and the reaction box is also installed on the outer wall of the tank. A fan is installed on the top of the reaction box, and a first pipe is installed at the input end of the fan, with one end extending into the tank. This device, by incorporating a cooling element, a filter screen, and a handle, achieves water recycling, reducing resource waste, and facilitating filter screen replacement. Steam enters the reaction box and is filtered by the filter screen to remove impurities. The filtered steam condenses into water droplets upon contact with the cooling element and is discharged through a second pipe, thus achieving water recycling and reducing resource waste. Pulling the handle moves the filter screen, which in turn moves a pulley, allowing the filter screen to be removed for easy replacement. This device achieves the functions of water recycling, reducing resource waste, and facilitating filter screen replacement.

[0004] Existing equipment for evaporating industrial salt typically involves filling the equipment with the industrial salt solution and evaporating it through continuous heating. During evaporation, the solution is usually stirred to improve evaporation efficiency. However, the stirring method is relatively simple, consisting of either horizontal or vertical stirring. The large volume of industrial salt solution inside the equipment creates significant resistance during stirring, resulting in poor stirring performance and negatively impacting the production of industrial salt. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A slider is slidably connected to the inner wall of the groove. The slider is connected to the stirring plate by bolts. The stirring plate is inclined. The number of stirring plates corresponds to the number of stirring blades. A connecting frame is bolted to the bottom of the stirring plate. The two ends of the shaft are rotatably connected to the opening by bearings. The outer wall of the shaft has a protrusion. A bushing is rotatably sleeved on the outer wall of the protrusion. The two ends of the connecting shaft are respectively connected to the bushing and the connecting frame by hinges. A pull-out opening is opened at the top of the opening. The pull-out opening is slidably connected to the connecting shaft. One end of the shaft extends to one side of the stirring blade. A gear set is provided between one end of the shaft and the inner wall of the evaporator.

[0008] Preferably, the gear set consists of a gear ring and a gear, and the gear ring and the gear mesh with each other. The outer wall of the gear ring is fixedly connected to the inner wall of the evaporator, and the gear is fixedly sleeved on the outer wall of the shaft.

[0009] Preferably, the bottom of the rotating rod is provided with a scraping mechanism, which consists of a block and multiple scrapers. The top of the block is connected to the rotating rod by bolts, and the multiple scrapers are fixed at equal intervals on the outer wall of the block. The scrapers are inclined and the bottom of the scrapers are in contact with the bottom inner wall of the evaporator.

[0010] Preferably, a discharge mechanism is provided between the two sides of the evaporator, and the discharge mechanism consists of two support frames, two connecting blocks and two rotating shafts. The two connecting blocks are symmetrically fixed to the two sides of the evaporator by bolts, and one side of each connecting block is connected to the two rotating shafts by bolts. The two support frames and the two rotating shafts are rotatably connected by bearings.

[0011] Preferably, one side of one of the support frames is bolted to a first motor, and one end of the first motor is bolted to one of the rotating shafts.

[0012] Preferably, the bottom of the stirring blade is provided with a groove, and a flipping mechanism is provided between the inner walls of the two sides opposite to the groove.

[0013] Preferably, the flipping mechanism includes a connecting rod, a sleeve, and multiple flipping blades. The two ends of the connecting rod are rotatably connected to the slot through bearings. The sleeve is fixedly sleeved on the outer wall of the connecting rod. The multiple flipping blades are fixed at equal intervals on the outer wall of the sleeve. One end of the connecting rod extends to one side of the stirring blade and is provided with a transmission component between it and the shaft.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention, through the provision of a horizontal and a vertical stirring mechanism, allows for the stirring of an industrial salt solution. The tank lid is opened, and the industrial salt solution is poured into the evaporator. The heater is then activated to evaporate the industrial salt solution. During evaporation, a second motor is activated, which drives the horizontal stirring mechanism to horizontally stir the industrial salt solution. During this horizontal stirring, gears, through the meshing of the gear ring, drive the shaft to rotate. The protrusion rotates along with the shaft, causing the connecting shaft to reciprocate up and down under the action of the protrusion and the bushing. This reciprocating motion of the stirring plate facilitates vertical stirring of the industrial salt solution. The vertical flow of the industrial salt solution is synchronized with the horizontal flow... The collisions between the industrial salt solutions enhance their flow through the resulting ripples. The combined use of horizontal and vertical stirring mechanisms allows for rapid and effective agitation, improving fluidity and preventing poor flow due to excessive resistance from a large volume of salt solution, which would negatively impact evaporation efficiency. Furthermore, the inclined stirring plates cause the solution to flow in a wave-like pattern to one side during reciprocating motion, further enhancing evaporation and accelerating the process.

[0017] 2. The present invention, through the setting of the flipping mechanism, when the shaft rotates under the meshing action of the gear and the gear ring, can drive the connecting rod to rotate through the transmission component, thereby causing the sleeve to drive the flipping blade to rotate synchronously with the connecting rod. During the rotation of the flipping blade, the industrial salt solution at the bottom of the evaporator will be flipped upward, so that the industrial salt solution collides with the horizontally flowing industrial salt solution when it flips upward, thereby further improving the fluidity of the industrial salt solution inside the evaporator, so as to accelerate the evaporation efficiency of the industrial salt solution.

[0026] Example 1: Refer to Figure 1-6 An evaporation device for producing refined industrial salt includes an evaporator 2 and a lid 5. A heater is bolted to the bottom outer wall of the evaporator 2. The evaporator 2 and the lid 5 are bolted together. A horizontal stirring mechanism 6 is provided at the bottom of the lid 5. The horizontal stirring mechanism 6 includes a rotating rod 11, a second motor 10, and multiple stirring blades 12. The top of the rotating rod 11 is fixedly connected to one end of the second motor 10. The second motor 10 is bolted to the top of the lid 5. Multiple stirring blades 12 are fixed at equal intervals on the outer wall of the rotating rod 11. An opening 15 is provided on one side of each stirring blade 12, and a vertical stirring mechanism 9 is provided between the opening 15 and the rotating rod 11. The cooperation of the horizontal stirring mechanism 6 and the vertical stirring mechanism 9 enables rapid and effective stirring of the industrial salt solution, thereby improving the fluidity of the industrial salt solution and preventing poor fluidity due to excessive resistance during stirring caused by a large amount of industrial salt solution, which would affect the evaporation efficiency of the industrial salt solution.

[0027] Based on the above, the vertical stirring mechanism 9 includes a connecting sleeve 18, multiple stirring plates 21, a shaft 23, and a connecting shaft 26. The connecting sleeve 18 is fixedly sleeved on the outer wall of the rotating rod 11. The outer wall of the connecting sleeve 18 is provided with multiple sliding grooves 19. A slider 20 is slidably connected to the inner wall of the sliding groove 19. The slider 20 is connected to the stirring plate 21 by bolts. The stirring plate 21 is inclined, and the number of stirring plates 21 corresponds to the number of stirring blades 12. A connecting frame is bolted to the bottom of the stirring plate 21. 22. The two ends of the shaft 23 are rotatably connected to the through-hole 15 by bearings. The outer wall of the shaft 23 is provided with a protrusion 24. The outer wall of the protrusion 24 is rotatably sleeved with a bushing 25. The two ends of the connecting shaft 26 are respectively connected to the bushing 25 and the connecting frame 22 by hinges. The top of the through-hole 15 is provided with a pull-out opening. The pull-out opening is slidably connected to the connecting shaft 26. One end of the shaft 23 extends to one side of the stirring blade 12. A gear set is provided between one end of the shaft 23 and the inner wall of the evaporator 2.

[0028] Based on the above, the gear set consists of a gear ring 27 and a gear 28, which mesh with each other. The outer wall of the gear ring 27 is fixedly connected to the inner wall of the evaporator 2, and the gear 28 is fixedly sleeved on the outer wall of the shaft 23. The gear 28 will drive the shaft 23 to rotate under the meshing action of the gear ring 27, and the protrusion 24 will rotate with the rotation of the shaft 23. At this time, the connecting shaft 26 will drive the stirring plate 21 to swing up and down under the action of the protrusion 24 and the bushing 25. Thus, the up and down swing of the stirring plate 21 can facilitate... The industrial salt solution is vertically stirred, causing collisions between the vertically flowing industrial salt solution and the horizontally flowing industrial salt solution. The resulting ripples from these collisions improve the flow of the industrial salt solution. The cooperation between the horizontal stirring mechanism 6 and the vertical stirring mechanism 9 allows for rapid and effective stirring of the industrial salt solution, thereby improving its fluidity and preventing poor fluidity due to excessive resistance during stirring caused by a large quantity of industrial salt solution, which would negatively impact the evaporation efficiency of the industrial salt solution.

[0029] Based on the above, a scraping mechanism 8 is provided at the bottom of the rotating rod 11, and the scraping mechanism 8 is composed of a block 13 and multiple scrapers 14. The top of the block 13 is connected to the rotating rod 11 by bolts, and multiple scrapers 14 are fixed at equal distances on the outer wall of the block 13. The scrapers 14 are inclined and the bottom of the scrapers 14 is in contact with the bottom inner wall of the evaporator 2.

[0030] Based on the above, a discharge mechanism is provided between the two sides of the evaporator 2. The discharge mechanism consists of two support frames 1, two connecting blocks 4 and two rotating shafts 7. The two connecting blocks 4 are symmetrically fixed to the two sides of the evaporator 2 by bolts. One side of the two connecting blocks 4 is connected to the two rotating shafts 7 by bolts. The two support frames 1 and the two rotating shafts 7 are rotatably connected by bearings.

[0031] Based on the above, one side of one of the support frames 1 is bolted to a first motor 3, and one end of the first motor 3 is bolted to one of the rotating shafts 7.

[0032] Example 2: Refer to Figure 1-7 An evaporation device for producing refined industrial salt, compared with Example 1, has a groove 16 at the bottom of the stirring blade 12, and a flipping mechanism 17 is provided between the inner walls of the opposite sides of the groove 16.

[0033] Based on the above, the flipping mechanism 17 includes a connecting rod, a sleeve 29 and multiple flipping blades 30. The two ends of the connecting rod are rotatably connected to the slot 16 through bearings. The sleeve 29 is fixedly sleeved on the outer wall of the connecting rod. The multiple flipping blades 30 are fixed at equal intervals on the outer wall of the sleeve 29. One end of the connecting rod extends to one side of the stirring blade 12 and a transmission assembly 31 is provided between it and the shaft 23.

[0034] Based on the above, the transmission assembly 31 consists of two pulleys 32 and a belt 33, and the two pulleys 32 and the belt 33 are rotatably connected. The two pulleys 32 are of different sizes. One pulley 32 is fixedly sleeved on the outer wall of the shaft 23, and the other pulley 32 is fixed on the outer wall of the connecting rod. When the shaft 23 rotates under the meshing action of the gear 28 and the gear ring 27, the transmission assembly 31 can drive the connecting rod to rotate, so that the sleeve 29 drives the tilting blade 30 to rotate synchronously with the connecting rod. During the rotation, the tilting blade 30 will tilt the industrial salt solution at the bottom of the evaporator 2 upward, so that the industrial salt solution collides with the horizontally flowing industrial salt solution when it tilts upward, thereby further improving the fluidity of the industrial salt solution inside the evaporator.

[0035] In summary, with the aid of the above-mentioned technical solution of the present invention: when stirring the industrial salt solution, the tank lid 5 is opened, the industrial salt solution is placed inside the evaporator 2, the heater is started, and the industrial salt solution is evaporated by the heater. During the evaporation process, the second motor 10 is started, which drives the transverse stirring mechanism 6 to stir the industrial salt solution transversely. During the transverse stirring, the gear 28 drives the shaft 23 to rotate under the meshing action of the gear ring 27, and the protrusion 24 rotates with the rotation of the shaft 23. At this time, the connecting shaft 26 will rotate between the protrusion 24 and the shaft. Under the action of sleeve 25, the stirring plate 21 is driven to swing up and down reciprocally. This up-and-down swinging of the stirring plate 21 facilitates vertical stirring of the industrial salt solution. The vertically flowing industrial salt solution collides with the horizontally flowing industrial salt solution, and the resulting ripples improve the flow effect. The cooperation of the horizontal stirring mechanism 6 and the vertical stirring mechanism 9 allows for rapid and effective stirring of the industrial salt solution, improving its fluidity and preventing excessive resistance during stirring due to a large volume of industrial salt solution. The poor fluidity affects the evaporation efficiency of the industrial salt solution. Furthermore, due to the inclined arrangement of the stirring plate 21, the industrial salt solution flows in a wave-like pattern to one side under the action of the inclined stirring plate 21 during its up-and-down reciprocating motion, further improving the fluidity of the industrial salt solution during evaporation and accelerating the evaporation process. When the shaft 23 rotates under the meshing action of the gear 28 and the gear ring 27, the transmission assembly 31 drives the connecting rod to rotate, causing the sleeve 29 to drive the tilting blade 30 to rotate synchronously with the connecting rod. During the rotation of the vane 30, the industrial salt solution at the bottom of the evaporator 2 will be turned upward, so that the industrial salt solution will collide with the horizontally flowing industrial salt solution when it is turned upward, thereby further improving the fluidity of the industrial salt solution inside the evaporator and accelerating the evaporation efficiency of the industrial salt solution. During this period, the scraper 14 will rotate with the rotating rod 11, which will facilitate the scraping of the industrial salt adhering to the bottom of the evaporator 2, so as to facilitate the discharge of the evaporated industrial salt. The first motor 3 is started, which will drive the evaporator 2 to turn, thereby facilitating the removal of the industrial salt inside the evaporator 2.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
