The crushing rollers are rotatably installed in the screening and crushing box 3 through support shafts. A transmission wheel is installed on the support shaft, and the transmission wheel is connected to the motor through a transmission belt or a transmission wheel.

[0033] The bottom of the screening and crushing box 3 is connected to a feeding auger assembly 6, and the output end of the feeding auger assembly 6 is connected to a dispersed feeding assembly 7. The crushed limestone can be transported to the dispersed feeding assembly 7 through the feeding auger assembly 6. The dispersed feeding assembly 7 is rotatably mounted on a frame 8. A water treatment box 9 is provided at the bottom of the dispersed feeding assembly 7. A plurality of inclined feeding pipes 10 are provided at one end of the dispersed feeding assembly 7 away from the feeding auger assembly 6. The plurality of feeding pipes 10 are all provided in the water treatment box 9. The limestone can be evenly dispersed into the water treatment box 9 around the circumference through the dispersed feeding assembly 7 and the feeding pipes 10, thereby improving the dispersion and uniformity of the limestone and thereby enhancing the water treatment effect. The tilted setting of the feeding pipes 10 facilitates the flow of limestone material in the feeding pipes 10.

[0034] In this embodiment, three feeding pipes 10 are arranged in a circle.

[0035] like Figure 1-Figure 4 As shown, the screening assembly 5 includes a screen plate 501, a vibrator 502 is installed at the bottom of the screen plate 501, and the screen plate 501 is installed obliquely between the two groups of crushing roller groups 4. The two ends of the oblique screen plate 501 are respectively connected to springs 503, which are installed on the support block 504, and the support block 504 is installed on the inner wall of the screening and crushing box 3.

The first drive motor 703 can drive the driving wheel 704 to rotate. During the rotation of the driving wheel 704, the driven wheel 702 is driven to rotate. During the rotation of the driven wheel 702, the feeding barrel 701 is driven to rotate synchronously. Since the feeding pipes 10 are radially arranged and installed on the feeding barrel 701, the feeding pipes 10 can be driven to rotate synchronously to achieve uniform dispersion of limestone.

The provision of the sealing ring 11 prevents limestone from escaping outward through the gap between the feeding barrel 701 and the discharge end of the feeding auger assembly 6 during feeding.

[0038] like Figure 1 and Figure 4 As shown, a distributor 13 is provided at one end of the feeding barrel 701 away from the driven wheel 702. The distributor 13 is arranged in a polygonal pyramid structure. The conical end of the distributor 13 faces the discharge end of the feeding auger assembly 6. The bottom of the distributor 13 is respectively connected to the inner wall of the feeding barrel 701. The distributor 13 divides the inner cavity of the feeding barrel 701 into a plurality of discharge ports 14. Each discharge port 14 is connected to the feeding pipe 10.

[0039] In this embodiment, the distributor 13 is designed in a triangular pyramid structure, and three corresponding discharge ports 14 are provided. Each discharge port 14 is connected to a corresponding feeding pipe 10 .

[0040] like Figure 3-Figure 4As shown, a plurality of feeding holes 15 are arranged at the bottom of the feeding pipe 10, and a discharge hole 16 is provided at one end of the feeding pipe 10 away from the feeding cylinder 701. The feeding holes 15 facilitate the limestone material to be evenly scattered into the water treatment box 9, and the discharge hole 16 can be used to discharge the limestone material remaining at the end of the feeding pipe 10.

[0041] like Figure 1-Figure 4 As shown, a plurality of support rods 17 are provided at one end of the feeding barrel 701 close to the feeding pipe 10. The support rods 17 are arranged corresponding to the feeding pipe 10, and a connecting rod 18 is connected between the support rods 17 and the feeding pipe 10. By arranging the support rods 17 and the connecting rods 18, the feeding pipe 10 can be supported and the structural strength of the feeding pipe 10 can be enhanced.

[0042] like Figure 1 As shown, a vibrating rod 19 for breaking up limestone arches is installed in the storage box 2. The vibrating rod 19 is provided to prevent the limestone in the storage box 2 from forming arches due to long-term storage and smooth material discharge. A control gate 20 is provided at the connection between the storage box 2 and the screening and crushing box 3, and the control gate 20 is used to control the connection and sealing between the storage box 2 and the screening and crushing box 3.

[0043] like Figure 1 As shown, the loading auger assembly 1 and the feeding auger assembly 6 both include a barrel 101, a second drive motor 102 is installed at one end of the barrel 101, a material shaft 103 is rotatably installed in the barrel 101 through a bearing, one end of the material shaft 103 is transmission-connected to the second drive motor 102, a spiral feeding blade 104 is provided on the material shaft 103, the material shaft 103 is driven to rotate by the second drive motor 102, and the spiral feeding blade 104 is driven to rotate synchronously during the rotation of the material shaft 103, and the limestone material is transported by the spiral feeding blade 104.

[0044] For ease of understanding, the working process of this embodiment is given below:

[0045] like Figure 1-Figure 4As shown, first, the limestone is transported to the storage box 2 through the feeding auger assembly 1. When the limestone needs to be added, the control gate 20 is opened, and the limestone in the storage box 2 enters the screening and crushing box 3. In the screening and crushing box 3, the limestone is first crushed by the crushing roller group 4 arranged near the top of the screening and crushing box 3. After the initial crushing, the limestone falls onto the screen plate 501 of the screening assembly 5. Under the vibration action of the vibrator 502, the limestone with larger particles after crushing falls into the crushing roller group 4 arranged near the bottom of the screening and crushing box 3 and undergoes secondary crushing. After that, the crushed limestone falls into the feeding auger assembly 6 and is transported to the dispersed feeding assembly 7 through the feeding auger assembly 6. The feeding barrel 701 is provided with a distributor 13, and the limestone is evenly dispersed to several discharge ports 14 through the distributor 13, and is transported to different feeding pipes 10 through the discharge ports 14. At the same time, the first drive motor 703 drives the feeding barrel 701 to rotate through the gear meshing of the driving wheel 704 and the driven wheel 702. The feeding pipe 10 is driven to rotate synchronously during the rotation of the feeding barrel 701. Since the feeding pipe 10 is tilted and several feeding holes 15 are arranged on the feeding pipe 10, the limestone will continuously fall from the feeding holes 15 into the water treatment tank 9 during the flow in the feeding pipe 10. During the continuous rotation of the feeding pipe 10, the limestone is evenly dispersed and delivered.

[0046] In summary, the utility model provides a limestone dosing device, which can crush the limestone multiple times through the cooperation of the crushing roller group and the screening component. By setting the dispersed feeding component and the feeding pipe, the limestone can be evenly distributed in the clean water storage box, thereby enhancing the dispersion and uniformity of the feeding, thereby improving the water treatment effect.
