Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] The following reference Figure 1-Figure 4 As shown, further described in combination with a specific embodiment, this embodiment provides an alkali solution dispensing device using waste alkali ash, including a tank body 1 and a conveying mechanism 2 arranged on one side of the tank body 1, a liquid inlet pipe 11 is arranged on one side of the top of the tank body 1, a liquid outlet pipe 12 is arranged on one side of the bottom of the tank body 1, the bottom wall of the tank body 1 is arranged obliquely, and the liquid outlet pipe 12 is arranged on one side of the tank body 1 close to the lowest end of the bottom wall, so that the alkali solution in the tank body 1 can fully flow out after the dispensing is completed. A stirring mechanism 13 is arranged in the tank body 1 to accelerate the dissolution rate of the alkali ash in the tank body 1.

[0026] Reference Figure 1 As shown, the conveying mechanism 2 includes a screw conveyor 21, the top of which is located at the upper part of the tank body 1 and is connected to the inside of the tank body 1 through a discharge pipe 22. A hopper 23 is arranged at the upper part of the lowest end of the screw conveyor 21, and the bottom of the hopper 23 is connected to the screw conveyor 21. A crushing roller 231 for crushing the waste alkali ash is arranged in the hopper 23. The waste alkali ash is poured into the hopper 23, and after being crushed by the crushing roller 231, it enters the screw conveyor 21 to avoid the large clumps of alkali ash gathered in the waste alkali ash from clogging the screw conveyor 21, and at the same time, the particle size of the waste alkali ash is reduced for rapid dissolution. The discharge pipe 22 is in a flared shape, and the area of ​​the end of the discharge pipe 22 located in the tank body 1 is larger than the area of ​​the end of the discharge pipe 22 close to the screw conveyor 21, so that the alkali ash can diffuse from the middle to both sides when entering the tank body 1, thereby improving the dissolution efficiency.

[0027] Reference Figure 2 , Figure 3As shown, a hollow storage barrel 3 is arranged inside the tank body 1 and outside the stirring mechanism 13, and one end of the discharge pipe 22 away from the screw conveyor 21 faces inside the storage barrel 3, so that the alkali ash does not directly contact the inner wall of the tank body 1, but can be dissolved in the tank body 1. The storage barrel 3 includes an inner water-permeable barrel 31, an outer water-permeable barrel 32 and a bottom collection plate 33, and the inner water-permeable barrel 31 and the outer water-permeable barrel 32 are connected as a whole by a plurality of connecting rods 34, and the bottom collection plate 33 is detachably connected between the inner water-permeable barrel 31 and the outer water-permeable barrel 32. The stirring mechanism 13 can cause the liquid in the tank body 1 to swirl, thereby accelerating the dissolution rate of the waste alkali ash in the storage barrel 3. Since the waste alkali ash is directly transported to the inside of the storage barrel 3 through the screw conveyor 21, the soluble part of the waste alkali ash is brought into the tank body 1 under the swirling action of the liquid, while the insoluble part is retained in the storage barrel 3. Therefore, the insoluble solid particles in the waste alkali ash will not collide with the inner wall of the tank body 1, nor will it cause the pipeline of the tank body 1 to be blocked.

[0028] Reference Figure 3 As shown, the bottom collecting tray 33 includes a conical portion 331 and a receiving portion 332. The conical portion 331 is located between the inner water-permeable cylinder 31 and the outer water-permeable cylinder 32, and the receiving portion 332 extends toward the inner circumferential surface of the inner water-permeable cylinder 31, that is, in vertical projection, the receiving portion 332 is located within the area enclosed by the water-permeable cylinder. The insoluble solid particles in the waste alkali ash settle in the bottom collecting tray 33 under the action of gravity, and enter the receiving portion 332 through the conical portion 331. By extending the receiving portion 332 toward the inside of the water-permeable cylinder, a larger storage space is provided for the insoluble solid particles. The top end of the receiving portion 332 is inserted into the inner water-permeable cylinder 31 and is provided with an external thread. The inner water-permeable cylinder 31 is provided with an internal thread that matches the external thread of the receiving portion 332; the top end of the conical portion 331 is provided with a slot 3311, and the bottom end of the outer water-permeable cylinder 32 is inserted into the slot 3311. The bottom collecting tray 33 is detachably mounted on the inner water-permeable cylinder 31 by means of a threaded connection, so that the bottom collecting tray 33 can be removed to pour out the precipitated solid particles and clean the inside of the bottom collecting tray 33 .

[0029] The stirring mechanism 13 includes a stirring motor 131, a stirring shaft 132 and a plurality of stirring blades 133. The stirring motor 131 is fixedly arranged on the top of the tank body 1, the stirring shaft 132 is arranged in the tank body 1, and the plurality of stirring blades 133 are distributed on the stirring shaft 132 along the length of the stirring shaft 132, and the height of the stirring blade 133 at the lowest end is higher than the height of the accommodating portion 332. The stirring motor 131 drives the stirring shaft 132 to rotate, and the plurality of stirring blades 133 can stir the solution, and a vortex can be caused in the solution during the stirring process, so that the alkali ash entering the storage barrel 3 is fully dissolved and mixed into the solution.

[0030] Reference Figure 3 , Figure 4 As shown, multiple groups of collecting components 4 for intercepting and collecting suspended impurities are distributed on the top of the storage barrel 3. The collecting components 4 include a collecting bucket 41 and a guide groove 42. A receiving cavity 14 for accommodating suspended impurities is provided circumferentially on the tank body 1. The tank body 1 is also provided with a driving mechanism 5 for driving the collecting components 4 to introduce the suspended impurities into the collecting cavity. Under the action of the stirring mechanism 13, the solution in the tank body 1 undergoes swirl flow, and at the same time, the soluble part of the waste alkali ash is dissolved into the solution, and some insoluble impurities will float on the liquid surface. With the swirl effect of the liquid, the insoluble impurities floating on the liquid surface will move along the circumferential direction of the storage barrel 3. Multiple groups of collecting components 4 can intercept the insoluble impurities in the corresponding area, and the collecting bucket 41 is driven to rotate by the driving mechanism 5, that is, the collected suspended impurities can be transported to the receiving cavity 14 through the guide groove 42.

[0031] Reference Figure 4 As shown, the collecting bucket 41 is a hollow net bucket, and a rotating shaft 411 is provided on the back of the collecting bucket 41 and is rotatably connected to the inner water-permeable cylinder 31 through the rotating shaft 411. When the collecting bucket 41 is rotated to a vertical state, the length direction is consistent with the axial direction of the inner water-permeable cylinder 31, and when the collecting bucket 41 is rotated to a horizontal state, the length direction is tangent to the circumferential direction of the inner water-permeable cylinder 31, and the collected impurities can be poured into the guide groove 42. A torsion spring 412 is provided between the rotating shaft 411 and the inner water-permeable cylinder 31 for driving the collecting bucket 41 to rotate to a vertical state; the guide groove 42 is obliquely arranged on one side of the back of the collecting bucket 41, and the end of the guide groove 42 away from the inner water-permeable cylinder 31 extends toward the direction close to the accommodating chamber 14, and the end of the guide groove 42 close to the inner water-permeable cylinder 31 is higher than the end of the guide groove 42 facing the accommodating chamber 14. In the absence of external forces, the collecting bucket 41 remains in a vertical state, and can intercept impurities suspended on the surface of the solution. When the intercepted impurities need to be discharged, the collecting bucket 41 is driven by the driving mechanism 5 to rotate to a horizontal state, so that the impurities collected in the collecting bucket 41 can be poured into the guide trough 42.

[0032] Reference Figure 3 As shown, the driving mechanism 5 includes a driving electric cylinder 51 and a driving ring 52. The driving ring 52 is arranged in the storage barrel 3 and is located at the lower part of the collecting assembly 4. The cylinder barrel of the driving electric cylinder 51 is fixedly arranged on the top of the tank body 1. The piston rod of the driving electric cylinder 51 extends into the storage barrel 3 and is fixedly connected to the driving ring 52. In the initial state, the piston rod of the driving electric cylinder 51 extends out of the cylinder barrel. When it is necessary to drive the collecting bucket 41 to rotate, the driving electric cylinder 51 is started and the piston rod of the driving electric cylinder 51 is moved into the cylinder barrel to drive the driving ring 52 to move upward. The driving ring 52 abuts against the bottom of the collecting bucket 41 and drives the collecting bucket 41 to rotate from a vertical state to a horizontal state to pour out the collected impurities.
