[0037] Example: Figure 1-8 As shown, a building material raw material dissolving device includes a hopper 1 and a stirring and conveying mechanism 2. A feed port 101 is provided on the top wall of the hopper 1. The longitudinal cross-section of the hopper 1 is arranged in an inverted triangle. An arc portion 102 is provided at the bottom of the hopper 1. The arc portion 102 is arranged tangent to the longitudinal side walls of the hopper 1. A water inlet 103 and a liquid outlet 104 are respectively provided at the lateral ends of the arc portion 102. The stirring and conveying mechanism 2 is rotatably assembled with the hopper 1. At least part of the stirring and conveying mechanism 2 is located in the arc portion 102 and is used to convey the material in the hopper 1 from the feed port 101 to the liquid outlet 104.

[0038] During operation, the raw material powder of the preset ratio of the water reducer is poured into the hopper 1 from the feed port 101, and the raw material slides along the inner wall of the hopper 1 into the arc-shaped portion 102. The water inlet 103 is connected to the water pipe and is used to introduce a predetermined amount of liquid water into the hopper 1. The liquid outlet 104 is connected to the liquid inlet of the liquid storage tank and is used to pass the mixed and dissolved water reducer solution in the hopper 1 into the liquid storage tank for storage. The stirring and conveying mechanism 2 stirs the raw materials in the hopper 1 and then conveys them, so as to improve the uniformity of the mixed and dissolved raw material powders. By setting the hopper 1 in an inverted triangle, the raw materials in the hopper 1 can slide naturally, reducing blockage and accumulation, which is conducive to improving the feeding efficiency and the conveying efficiency of the stirring and conveying mechanism 2.

[0039] By providing a stirring and conveying mechanism 2, the raw material powder is ensured to be evenly dispersed in the water. The raw material is stirred while being conveyed, thereby reducing the fluctuation of product quality caused by uneven dissolution, which is beneficial to the stability of concrete performance. The raw material dissolving device is used to pre-mix and dissolve the raw material with water. Under the flushing of the water flow, the contact rate between water and the raw material is increased, so that the raw material and water can be mixed more quickly, the dissolution efficiency is improved, and the overall dissolution time is reduced. Of course, in order to increase the flushing intensity of the water flow on the raw material, the liquid water can be pressurized and then introduced from the water inlet 103. The device can adapt to the production and processing of different types of powdered raw materials and water solutions, has good versatility, and is suitable for the production of various water reducers.

[0040] In terms of the inclination angle of the hopper 1 , the longitudinal section of the hopper 1 is arranged in an inverted isosceles triangle, and the angle between the two inclined side walls of the hopper 1 is 30° to 60°, preferably 50°.

[0041] In order to make the reducing agent discharged from the liquid outlet 104 be better transported to the liquid storage tank, in this embodiment, the cross-section of the liquid outlet 104 is reduced to achieve a pressurization effect. This embodiment also includes a liquid guide cylinder 3, the inner wall of the liquid guide cylinder 3 is set in a truncated cone shape, the liquid guide cylinder 3 is assembled on the inner wall of the arc portion 102, the lower bottom of the liquid guide cylinder 3 is set toward the water inlet 103, the upper bottom of the liquid guide cylinder 3 is connected to the liquid outlet 104, the stirring and conveying mechanism 2 is located between the water inlet 103 and the lower bottom of the liquid guide cylinder 3. It is worth noting that the larger bottom of the liquid guide cylinder 3 The surface is called the lower bottom, and the smaller bottom surface of the liquid guiding tube 3 is called the upper bottom. The longitudinal cross-section of the liquid outlet 104 is smaller than the longitudinal cross-section of the liquid inlet. By reducing the cross-section of the liquid outlet 104, the pressure of the liquid when flowing out is increased, the transportation efficiency from the liquid outlet 104 to the liquid storage tank is improved, and the time of the entire production process is shortened, so that the water reducer solution can be more efficiently transported to the liquid storage tank. The frustum-shaped liquid guiding tube 3 guides the dissolved solution, which helps the liquid to flow smoothly, reduces the generation of foam caused by turbulence, and ensures the stability and quality of the water reducer solution.

[0042] In order to reduce the residual solution in the material guiding barrel, in the horizontal projection direction of the hopper 1, the liquid outlet 104 and the water inlet 103 are inscribed, and the liquid outlet 104 is located in the vertical axis direction of the water inlet 103. The line between the upper bottom circle center and the lower bottom circle center of the liquid guiding barrel 3 is gradually tilted from top to bottom, so that the flow path of the solution in the material guiding barrel is smoother, reducing the adhesion and residue of the solution on the inner wall of the material guiding barrel, and improving the transfer efficiency of the solution. Secondly, the liquid guiding barrel 3 with an inclined axis allows the solution to flow out naturally from the liquid outlet 104 under the action of gravity in the liquid guiding barrel 3, reducing the need for additional power to push, preventing the solution from accumulating in the liquid guiding barrel 3, and improving the overall fluid transmission efficiency.

[0043] Since a material guide barrel is provided in the hopper 1, the lateral length of the stirring and conveying mechanism 2 is shortened, so that when the raw materials are poured from the feed port 101, part of the materials remain on the outer wall of the material guide barrel and cannot be effectively conveyed by the stirring and conveying mechanism 2. In order to solve the above technical problems, the present embodiment also includes an inclined plate 4, which is used to connect the side wall of the discharge port located in the vertical axis direction of the liquid outlet 104 and the lower bottom outer wall of the liquid guide barrel 3. By providing the inclined plate 4, a smooth surface is provided, which can guide the raw materials to slide from the feed port 101 to the stirring and conveying mechanism 2, reducing the residue of materials on the outer wall of the material guide barrel, thereby improving the overall material conveying efficiency, ensuring that the raw materials in the hopper 1 can be effectively stirred by the stirring and conveying mechanism 2, improving the uniformity of the water reducer solution, and making the quality of the produced water reducer products more stable.

[0044] In order to improve the smoothness of the raw materials sliding on the inclined plate 4, the angle between the inclined plate 4 and the side wall of the hopper 1 where the liquid outlet 104 is opened is 30° to 45°, preferably 30°.

[0045] In terms of the specific structure of the stirring and conveying mechanism 2, the stirring and conveying mechanism 2 includes an auger 201. The outer diameter of the blades of the auger 201 is adapted to the inner wall of the arc-shaped portion 102. The axis of the rotating shaft of the auger 201, the center axis of the arc-shaped portion 102, and the axis of the water inlet 103 are colinearly arranged. When the stirring and conveying mechanism 2 is in operation, the blades of the auger 201 rotate efficiently driven by the water flow of the water inlet 103, thereby realizing rapid stirring and conveying of raw materials and improving production efficiency. The continuous rotation of the auger 201 can ensure that the raw materials and water are fully mixed, so that the uniformity of the water reducer solution is guaranteed and the quality stability of the product is improved. Secondly, the water flow power of the water inlet 103 is used to drive the auger 201 to rotate, which reduces dependence on external energy and reduces energy consumption in the production process. By adjusting the flow rate of the water inlet 103, precise control of the stirring and conveying process can be achieved.

[0046] In the specific structure of the rotational assembly of the stirring and conveying mechanism 2 and the hopper 1, the water inlet 103 is connected to the connecting flange 1031, the stirring and conveying mechanism 2 includes a connecting block 202, one end of the connecting block 202 is rotatably assembled with the rotating shaft of the auger 201 through a bearing, the connecting flange 1031 is provided with a connecting groove for assembling the connecting block 202, and the other end of the connecting block 202 is assembled in the connecting groove. Since the radial equiangular circumference of the connecting flange 1031 is provided with a plurality of groups of connecting holes 1032, the connecting groove is opened at a position that coincides with a group of connecting holes 1032 thereof, and at the end of the connecting block 202 away from the hinge rotating shaft An assembly hole 2021 is provided which is compatible with the connecting hole 1032. When the connecting flange 1031 is screwed to the flange of the water pipe, the connecting block 202 is also fixed and limited, thereby completing the rotational assembly of the auger 201 and the hopper 1. By using the design of the connecting flange 1031 and the connecting block 202, the rotational assembly process of the auger 201 and the hopper 1 is simplified, making installation and maintenance faster and more convenient. Secondly, the fixed limiting design of the connecting block 202 and the connecting flange 1031 enhances the connection stability between the auger 201 and the hopper 1, and reduces vibration and displacement during operation.

[0047] In addition, this embodiment provides another way of rotating and assembling the stirring and conveying mechanism 2 and the hopper 1. The arc portion 102 is arranged in a circle, and its arc length is greater than 180°, preferably 200°. The arc portion 102 is designed to pass through a semicircular structure to limit the auger 201 within the arc portion 102 and rotate under the impact of the water flow.

[0048] When the raw material powder is poured into the hopper 1, since the raw material powder is in a piled state, it is not easy to slide to the stirring and conveying mechanism 2 for stirring and conveying. In order to loosen the piled raw material powder, this embodiment also includes a loosening mechanism 5 for loosening the raw materials accumulated in the hopper 1. The loosening mechanism 5 also includes a loosening blade 501 and a hinge shaft 502. One end of the hinge shaft 502 is rotatably assembled with the loosening blade 501, and the other end of the hinge shaft 502 is connected to the side wall of the hopper 1. At least part of the loosening blade 501 is exposed to the inlet. The top wall of the feed port 101 pushes the part of the loosening blade 501 exposed outside the top wall of the feed port 101, so that the loosening blade 501 swings in the hopper 1, thereby loosening the raw material powder accumulated in the hopper 1, making it easier for the raw material to slide into the stirring and conveying mechanism 2 for stirring and conveying. By providing a loosening mechanism 5, the accumulated raw material powder can be effectively loosened, the fluidity of the raw material can be improved, and the raw material can be more easily slid into the stirring and conveying mechanism 2, thereby improving the overall stirring and conveying efficiency and ensuring the quality of the water reducer solution.

[0049] In terms of the specific structure of the loosening blade 501, the loosening blade 501 is provided with an inclined portion 5011 at one end close to the stirring and conveying mechanism 2, which is conducive to the sliding of raw materials. The end of the loosening blade 501 exposed to the feed port 101 is provided with an inverted L-shaped portion 5012, and a gap is provided between the inverted L-shaped portion 5012 and the top wall of the feed port 101 for the loosening blade 501 to swing back and forth. The design of the inclined portion 5011 at one end of the loosening blade 501 close to the stirring and conveying mechanism 2 helps the raw material powder to slide on the inclined surface, reduces the accumulation of raw materials in the hopper 1, and improves the transportation efficiency of the raw materials to the stirring and conveying mechanism 2. Secondly, the setting of the inverted L-shaped portion 5012 allows the loosening blade 501 to swing back and forth in the gap of the top wall of the feed port 101. This design increases the swing range and efficiency of the loosening blade 501, thereby more effectively loosening the accumulated raw material powder.

[0050] In terms of the specific structure for realizing the back-and-forth swinging of the loosening blades 501, the loosening mechanism 5 also includes a connecting rod 503 and a loosening cylinder 504. There are multiple groups of loosening blades 501 arranged at equal intervals along the transverse direction of the hopper 1. The connecting rod 503 is used to connect the multiple groups of loosening blades 501. The fixed end of the loosening cylinder 504 is connected to the hopper 1, and the pushing end of the loosening cylinder 504 is connected to the connecting rod 503. The multiple groups of loosening blades 501 are arranged at equal intervals along the transverse direction of the hopper 1. Through the connection of the connecting rod 503 and the push of the loosening cylinder 504, the raw materials can be evenly dispersed in the hopper 1, avoiding local accumulation of raw materials and improving the uniformity of stirring. Through the cooperation of the loosening cylinder 504 and the connecting rod 503, the swing frequency and amplitude of the loosening blades 501 can be controlled.

[0051] After the raw materials are added to the hopper 1 according to the preset ratio, the raw material powder will remain on the inner wall of the material. In order to facilitate the flushing of the raw materials remaining on the inner wall of the hopper 1 and then pumping them into the liquid storage tank, the water inlet 103 is provided with a first valve, and the liquid outlet 104 is provided with a second valve. The second valve and the liquid inlet of the liquid storage tank are connected to a water pump, and the water pump is used to pump the solution in the hopper 1 into the liquid storage tank. When the raw materials are added and there is no raw material accumulated in the hopper 1, the second valve is closed, and then liquid water is input into the hopper 1 from the liquid inlet so that the water level is flush with the feed inlet 101. Then, the first valve is closed so that the liquid water can soak the inner wall of the hopper 1, thereby dissolving the raw material powder remaining on the inner wall of the hopper 1. Subsequently, the second valve and the water pump are opened to pump the liquid in the hopper 1 into the liquid storage tank, so that the raw material residue can be reduced and the cleaning work of the hopper 1 can be reduced. At the same time, reducing the raw material residue can ensure that the water reducer reaches the solute of the preset ratio and reduce the quality fluctuation of the water reducer.

[0052] It is worth mentioning that the building material raw material dissolving device in this embodiment is suitable for the dissolution process of powdered raw materials and water. In this embodiment, the dissolving device is used for water reducing agent, which is the best implementation method.

[0053] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
