The material-water ratio cannot be dynamically adjusted in the production process, resulting in thick or thin slurry. Single device combination will cause the function to be fixed and unable to flexibly switch between "full crushing" and "deslagging and purification", which is poor in flexibility. SUMMARY

One end of the shunt assembly is in communication with the feed hopper, forming a self-circulating crushing system. A deslag slurry separation assembly is arranged on the mounting rack, and a deslag outlet and a slurry outlet are arranged on the deslag slurry separation assembly. The other end of the shunt assembly is in communication with the inlet of the deslag slurry separation assembly, forming a deslag slurry separation system.
[0005] As a further improvement of the above technical scheme: As an optimization scheme of the above technical scheme, the material crushing mechanism comprises a material crushing workbench arranged on the mounting rack, a crushing drive motor arranged in the material crushing workbench and having an output shaft penetrating through the upper surface of the material crushing workbench, a crushing cavity arranged on the material crushing workbench, a high-speed rotating impeller located in the middle of the crushing cavity and fixedly connected with the output shaft of the crushing drive motor, and a filter screen fixedly arranged on the crushing cavity and located outside the high-speed rotating impeller. The finished product discharge port is located outside the crushing cavity and in communication with the inside of the crushing cavity.
[0006] As an optimization scheme of the above technical scheme, a finished product discharge space is arranged between the filter screen and the inner wall of the crushing cavity.

[0008] An optimized version of the above technical solution is that the slag-containing slurry conveying assembly includes a slag-containing slurry conveying cavity fixedly disposed on the material crushing workbench, and a conveying impeller located inside the slag-containing slurry conveying cavity and fixedly connected to the output shaft of the crushing drive motor.
[0009] An optimized version of the above technical solution is that the upper end of the conveying impeller is provided with several inclined discharge blocks arranged in a circular array.
[0010] An optimized version of the above technical solution is that the diversion component includes a main conveying pipe connected to the outlet of the slurry conveying component, a three-way ball valve connected to the other side of the conveying pipe, a circulating conveying pipe and a separating conveying pipe connected to the other two ends of the three-way ball valve, the circulating conveying pipe being connected to the feed hopper, and the separating conveying pipe being connected to the inlet of the slurry separation component.
[0011] An optimized version of the above technical solution is as follows: the slurry separation assembly includes a separation frame fixedly mounted on the mounting frame, a separation drive motor mounted on one side of the separation frame, a slag discharge screw rotatably mounted inside the separation frame and fixedly connected to the output shaft of the separation drive motor, and a slurry inlet located at the upper end of the separation frame and at the end of the slag discharge screw near the separation drive motor.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] As attached Figure 1 To be continued Figure 5 As shown, this technical solution mainly targets the crushing of grains and the separation of impurities. The specific solution is described below: 1. To improve the fineness requirements after crushing, this technical solution incorporates a self-circulating mode, repeatedly crushing the material multiple times. The required fineness is achieved through multiple cyclic crushing processes, as shown in the attached diagram. Figure 1 Appendix Figure 2 Appendix Figure 3 With appendix Figure 5 As shown, the structure for implementing this function is described below: 1.1 Mounting frame 1, used to install and fix all components; 1.2 Feed hopper 2, which is installed on the upper end of the mounting frame 1 and is used to convey materials; 1.3 The material crushing workbench 3 is mounted on the mounting frame 1, and a crushing drive motor 4 is installed inside it. The output shaft of the crushing drive motor 4 passes through the upper surface of the material crushing workbench 3. 1.4 Slag-containing slurry conveying assembly, used for conveying slurry containing slag, specifically, a slag-containing slurry conveying cavity 11 is fixedly installed on the upper surface of the material crushing workbench 3. The slag-containing slurry conveying cavity 11 has a conveying impeller 12 inside, which is fixedly connected to the output shaft of the crushing drive motor 4. At the same time, several inclined discharge blocks 13 are provided on the upper end of the conveying impeller 12 to assist in discharge.
[0023] 1.5 Material crushing mechanism, used to crush and pulverize grain materials. Its specific structure is a crushing chamber 5 fixedly installed at the upper end of the slurry conveying chamber 11 containing slag. The inlet at the upper end of the crushing chamber 5 is connected to the inlet of the feed hopper 2. A high-speed rotating impeller 6 is set in the middle of the crushing chamber 5. The high-speed rotating impeller 6 is also fixedly connected to the output shaft of the crushing drive motor 4, sharing a drive motor, which makes the overall structure simpler.
[0024] A filter screen 7 is installed inside the crushing chamber 5. The filter screen 7 is located around the high-speed rotating impeller 6. A finished product discharge space 8 is provided between the filter screen 7 and the inner wall of the crushing chamber 5. The finished product discharge space 8 is connected to the finished product outlet 9 for discharging the processed finished product. Several large particle passage channels 10 are provided at the bottom of the crushing chamber 5. The large particle passage channels 10 are located below the high-speed rotating impeller 6 and are used to discharge slag that cannot pass through the filter screen 7 into the slag-containing slurry conveying chamber 11.
[0025] 1.6 Diversion Component: The diversion component is mainly used to transport slag in the slag-containing slurry conveying component. It mainly includes a main conveying pipe 14, a circulating conveying pipe 16, and a separation conveying pipe 17. The three pipes are connected by a pneumatic three-way ball valve 15. The two ends of the main conveying pipe 14 are respectively connected to the slag-containing slurry conveying chamber 11 and the inlet end of the three-way ball valve 15. The circulating conveying pipe 16 and the separation conveying pipe 17 are respectively connected to the outlet end of the three-way ball valve 15. The circulating conveying pipe 16 is connected to the feed hopper 2.
[0026] The self-circulation mode of this technical solution is mainly adjusted by the pneumatic three-way ball valve 15, so that the main conveying pipeline 14 is connected to the circulating conveying pipeline 16. The raw material enters the crushing chamber 5 from the feed hopper 2. In the crushing chamber 5, the high-speed rotating impeller 6 (rotor linear speed 12-18m / s) and the filter screen 7 (stator) are subjected to strong shearing and impact. The easily crushed material particles pass through the filter screen 7 under the action of centrifugal force and are discharged from the finished product outlet 9 as the primary processed finished product.
[0027] Large particles (containing slag) that do not pass through the screen are fed into the slurry conveying chamber 11 along with the slurry through the crushing chamber 5. The large particles are fed into the trough 10 (the width of which is controlled according to the gap of different materials, usually 1-5mm).
[0028] The conveying chamber 11 for slag-containing slurry has a built-in impeller 12 with four evenly distributed involute curved blades (blade curvature radius 50-100mm, blade inclination angle 15°-25°). The speed is controlled by a variable frequency motor to generate a stable vortex field. The slag-containing slurry is thrown against the chamber wall by centrifugal force and returns to the feed hopper 2 through the main conveying pipe 14 and the circulating conveying pipe 16 to start self-circulation. The conveying impeller 12 adopts unique involute curved blades to optimize the flow trajectory of the material. For high-concentration materials (solid content 40%-60%), the conveying efficiency is increased by 30% (compared to straight impellers, the impeller speed is reduced by 20% and energy consumption is reduced by 15% under the same working conditions).
[0029] The purpose of self-circulation is to allow the slurry from the slag-containing slurry conveying chamber 11 to be directly returned to the feed hopper 2 when the fineness of the slurry does not meet the requirements, so that the fineness of the material can be achieved through multiple cycles of crushing.
[0030] 2. Slurry separation mode, mainly for separating the crushed slag from the slurry, as shown in the attached... Figure 1 With appendix Figure 4 As shown, the specific structure to implement this function is as follows: 2.1 Separation frame 18 is fixedly installed on the mounting frame 1 for installing and fixing the slurry separation components. A slurry inlet 21 is provided on the separation frame 18, and the slurry inlet 21 is connected to the separation and conveying pipeline 17 of the separation component. 2.2 The slag discharge screw 20 is horizontally rotatably mounted on the separator 18. The slag discharge screw 20 adopts a gradual pitch design, compressing from 80mm at the feed end to 20mm at the discharge end, with a compression ratio of 1:4. 2.3 Separation drive motor 19 is set at one end of the separation frame 18, and the drive shaft is fixedly connected to the slag discharge screw 20; 2.4 Slag outlet 22 is located at the other end of the separator 18 and is used to discharge slag into the slag collection bucket for slag collection. 2.5 The slurry outlet 23 is located below the slag discharge screw 20 and is funnel-shaped. A buffer box is provided below the slurry outlet 23 for collecting the slurry.
[0031] The self-circulation mode of this technical solution is mainly adjusted by the pneumatic three-way ball valve 15, so that the main conveying pipeline 14 is connected to the separation conveying pipeline 17. The slurry enters the separation frame 18. Through the rotation of the slag discharge screw 20, under the back pressure of 2-3 bar, the slurry is subjected to the dual action of axial compression and radial shear in the screw. The free slurry is forced to be filtered out, while the slag (the moisture content can be reduced to below 60%) is discharged through the slag discharge port (13) and discharged to the slag collection bucket (14). The slurry flows to the buffer tank 24 (11).
[0032] The purpose of slurry separation mode is when the process requires the removal of impurities such as fibers from the material.
[0033] 3. Secondary circulation mode mainly involves secondary recycling of the slurry in the buffer tank, followed by multiple crushing processes to increase the yield of finished product per unit weight. To achieve the above functions, see attached... Figure 1 With appendix Figure 2 As shown, the specific structure is as follows: A centrifugal pump 25 is installed below the mounting frame 1. The inlet of the centrifugal pump 25 is connected to the buffer tank through the secondary circulation pipe 26, and the outlet of the centrifugal pump 25 is connected to the feed hopper 2 through the secondary circulation pipe 26, thus forming a secondary circulation system.
[0034] The material is pumped to the feed hopper 2 by centrifugal pump 25, where it is mixed with fresh material and pulverized multiple times to finally meet the fineness requirements specified by the customer (the finest fineness can be 300 mesh), thus completing continuous production.
[0035] The above are merely preferred embodiments 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.
