DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-Figure 6A chemical raw material production reaction dissolution device includes a dissolution tank, which includes a tank body 1 with an opening on the top. A top cover 2 is installed on the top of the tank body 1 through a flange to facilitate opening the dissolution tank and cleaning the inside thereof.

[0028] At least three support legs 28 are installed at intervals along the edge of the bottom of the dissolving tank (i.e., the bottom of the tank body 1), and a lower hopper 3 is installed on the top side of the dissolving tank (i.e., the top side of the top cover 2). Two parallel grinding rollers 4 are arranged inside the lower hopper 3, and the two grinding rollers 4 correspond to each other, and the ends of the grinding rollers 4 are rotatably connected to the inner wall of the lower hopper 3. One end of the grinding roller 4 passes through the lower hopper 3 and is connected to a first gear 5, and the two first gears 5 are meshed, and a first drive motor 6 is installed at the other end of one of the grinding rollers 4. The first drive motor 6 is fixed to the outer wall of the lower hopper 3 through a bracket. When in use, the raw materials to be reacted and dissolved are poured from the lower hopper 3. With the transmission of the first gear 5, the two grinding rollers 4 are moved relative to each other, thereby grinding the raw materials falling into the lower hopper 3, so that large particles of the raw materials are ground into small particles, so that they can react and dissolve faster later.

[0029] In order to ensure that the raw materials can fully fall between the two grinding rollers 4 when entering the lower hopper 3, Figure 3 As shown, an inclined convergence plate 7 is provided at the upper end of the side relatively away from the two grinding rollers 4, the top of the convergence plate 7 is fixed to the inner wall of the lower hopper 3, and the convergence plate 7 is arranged toward the gap between the two grinding rollers 4. After the raw materials falling into the lower hopper 3 come into contact with the convergence plate 7, they will slide along the convergence plate 7 toward between the two grinding rollers 4, so that the grinding rollers 4 can fully grind the raw materials.

[0030] like Figure 1 and Figure 4 As shown, a stirring shaft 8 is arranged inside the dissolving tank, and the ends of the stirring shaft 8 are rotatably connected to the upper and lower ends of the dissolving tank, that is, the top of the stirring shaft 8 is rotatably mounted on the top cover 2, and the bottom of the stirring shaft 8 is rotatably mounted on the bottom of the tank body 1. The top of the stirring shaft 8 passes through the top of the dissolving tank and is connected to a driving mechanism, and a stirring blade 19 is also arranged on the stirring shaft 8, and one end of the stirring blade 19 is connected to a fixing seat 20, and the fixing seat 20 is fixed to the stirring shaft 8. The stirring blade 19 rotates, and the raw materials can flow together with the rotation of the stirring blade 19 in the tank body 1, so that the raw materials are more fully contacted with each other, so as to improve the reaction and dissolution rate between the raw materials;

[0031] Among them, the driving mechanism includes a second gear 9, which is coaxially installed on the stirring shaft 8, and a third gear 10 is meshed on the side of the second gear 9, and a driving shaft 12 is coaxially installed on the third gear 10. The bottom of the driving shaft 12 is fixed on the top cover 2, and the top of the driving shaft 12 is connected to a second driving motor 11. The second driving motor 11 is connected to the top cover 2 through a bracket. The stirring shaft 8 is transmitted between the second gear 9 and the third gear 10 to rotate under the action of the second driving motor 11. In actual use, the second driving motor 11 can be set away from the lower hopper 3, so that the lower hopper 3 can select a larger volume as much as possible, so that more raw materials can be poured into the lower hopper 3 at the same time.

[0032] It should be noted that a slip ring is installed on the top of the stirring shaft 8, and the slip ring includes a rotor 14 and a stator 13. The stator 13 is fixed on the top of the stirring shaft 8, and the rotor 14 is rotatably installed on the stator 13; the stirring shaft 8 is a hollow tube, and a heating plate is installed on the outer wall of the stirring blade 19. The power supply wire of the heating plate is arranged in the stirring shaft 8 and connected to the stator 13. Because the reaction between the raw materials requires high temperature conditions, the heating plate can be turned on to heat the raw materials when the raw materials are stirred in the tank body 1, thereby ensuring the normal reaction between the raw materials and helping the dissolution of the raw materials.

[0033] Specifically, when the raw material falls from the lower hopper 3 into the tank body 1, Figure 4 and Figure 6 As shown, an annular plate 16 is coaxially arranged above the inside of the dissolving tank, and an inclined first guide plate 17 is connected to the inner wall of the annular plate 16. The other end of the first guide plate 17 is connected to the mounting seat 15, and the mounting seat 15 is fixed to the stirring shaft 8. An inclined second guide plate 18 is connected to the bottom of the first guide plate 17, and the ends of the second guide plate 18 are respectively fixed to the annular plate 16 and the mounting seat 15. In actual use, the angle between the first guide plate 17 and the second guide plate 18 is A, 90°≤A≤ 180°, the raw materials falling from the lower hopper 3 will fall on the continuously rotating guide plate. Due to the inclined setting of the guide plate, the raw materials in contact with the guide plate will have a tendency to slide down along the guide plate, and as the guide plate rotates, the raw materials on the guide plate will also be brought to a position not corresponding to the lower hopper 3 by the rotating guide plate during the sliding process, so that the raw materials can fall downward in a dispersed manner, so that the raw materials can have more sufficient and uniform contact with each other, so as to prevent the raw materials from being too concentrated, and the stirring blades 19 will find it difficult to fully stir the raw materials in a short time, thereby affecting the reaction and dissolution of the raw materials.

[0034] Furthermore, an annular support seat 21 is installed along the outer wall edge of the annular plate 16, and an annular bearing seat 22 is coaxially arranged below the support seat 21. The bearing seat 22 is fixed to the inner wall of the tank body 1, and a plurality of spaced balls 23 are rotatably installed on the top and inner wall of the bearing seat 22. The balls 23 correspond to the bottom of the support seat 21 and the outer wall of the annular plate 16. While ensuring the normal rotation of the annular plate 16, the guide plate is supported to reduce the probability of damage to the stirring shaft 8, the guide plate, etc.

[0035] Finally, an annular guide plate 24 is provided at the bottom of the tank body 1, and a discharge port 25 is provided at the bottom of the tank body 1, and a discharge pipe 26 is provided below the discharge port 25, and the discharge pipe 26 is fixed to the bottom of the tank body 1, and a solenoid valve 27 is installed on the discharge pipe 26. After the reaction and dissolution of the raw materials are completed, the solenoid valve 27 is opened to release the raw materials from the tank body 1 to realize the discharge operation of the raw materials.

[0036] It should be further explained that, in order to facilitate the staff to observe the reaction and dissolution status of the raw materials during the raw material production process, a window 29 is provided on the side wall of the tank body 1 , and a visual glass 30 is installed in the window 29 .

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
