[0021] Please see Figure 1-6 The present invention provides a technical solution: A multi-functional integrated pulping machine, comprising: The frame includes a support 101 and a flat disk 102; The grinding unit 1, which is mounted on the frame, is used to grind materials and separate slurry from slag.

[0024] As an improvement, such as Figure 3 As shown, the upper grinding plate 193 is installed on the lower part of the cover plate 19, and an annular water channel 192 is provided inside. A second water spray nozzle 1921 is provided on the annular water channel 192, which penetrates into the interior of the upper grinding plate 193. A metering pump 194 is connected to the annular water channel 192. The upper grinding plate 193 has a water channel and multiple water outlets 1931 inside. The cover plate 19 has a slurry inlet 191 on one side that communicates with the interior of the integrated spiral blower 4.

[0025] Furthermore, such as Figure 4 As shown, the cover plate 19 has a hanging pipe 195 at its center. The hanging pipe 195 has an exhaust hole 1951 at its upper part. The exhaust hole 1951 is covered with a sealing sleeve 1952 for discharging the gas inside the hanging pipe 195. The conveying pipe 22 of the feeding unit 2 is connected to the hanging pipe 195.

[0027] Among them, such as Figure 2 As shown, in the feeding unit 2, the screw conveyor 21 includes a second screw blade 211, the head of the second screw blade 211 is provided with a second circular plate 212, the second circular plate 212 is opposite to the flat plate 213 provided below, and the flat plate 213 is provided with holes for material to pass through.

[0028] In addition, the cleaning and filtering unit 3 also includes a cylindrical protective cover 34, the inner wall of which is provided with a cleaning water pipe with spray holes 35; and a gear pump 321 is provided on the soy milk extraction pipe 32.

[0029] As an improvement, such as Figure 2-3 As shown, the inner hole of the third disk 17 extends downward to form a protective sleeve 125; a threaded hole is provided at the center of the top end of the spline shaft 122, and a fastener passes through the gasket and the second spring 16 in the protective sleeve 125 in sequence and is threadedly connected to the threaded hole.

[0031] It should be noted that, in the specific implementation of this invention, such as... Figure 1-2 As shown, when the motor 12 starts, the centrifugal slider 13 slides outward centrifugally. The inclined surface at its upper end pushes up the second disc 15, compresses the second spring 16, and pushes the third disc 17 and the lower grinding plate 18 to move upward and press against the upper grinding plate 193. After wear, the pressure decreases, the motor speed increases, the centrifugal slider 13 slides outward further and is locked in position by the wedge 14, so that the second spring 16 is further compressed to compensate for the pressure. The adjusting nut 143 can adjust the initial pressure. After the motor stops, the limit spring 112 and the reset spring 152 reset each component.

[0032] like Figure 2-3As shown, the lower part of the cover plate 19 is equipped with an upper grinding plate 193, and an annular water channel 192 is provided inside. The second water spray nozzle 1921 on it leads to the interior of the grinding plate for cooling. The downward pipe 195 in the center of the cover plate 19 is used for feeding.

[0033] like Figure 2 As shown, the feeding unit 2 includes a screw conveyor 21 and a blower 23. The second circular piece 212 at the end of the second screw blade 211 of the screw conveyor 21 cooperates with the flat plate 213 to feed soybeans into the conveying pipe 22. The blower 23 blows the soybeans into the hanging pipe 195. The gas is discharged from the exhaust hole 1951 through the closed sleeve 1952, and the soybeans fall into the grinding area.

[0034] like Figure 2 , Figure 6 As shown, in the spiral blower integrated machine 4, slurry enters the spiral chamber 44 from the slag outlet 191 and is conveyed and squeezed by the first spiral blade 41. When the extrusion port 412 of the first disc 411 at the end of the first spiral blade 41 rotates to align with the sub-hole 431 of the extrusion plate 43, the slurry is squeezed out to the air duct 42 and carried away by high-pressure gas. The air inlet 441 on the side wall of the spiral chamber 44 intermittently introduces air through the gas input pipe 442 with air valve 443 for cleaning and sealing.

[0035] like Figure 2 , Figure 5 As shown, after being filtered by the metal filter screen 171, the slurry flows into the collection chamber composed of the cylindrical protective cover 34 and the flat disc 102, and is pumped out by the gear pump 321 through the soy milk extraction pipe 32. The soy milk extraction pipe 32 is equipped with a soy milk concentration monitor 33, which is used to control the water supply of the metering pump 194. The inner wall of the cylindrical protective cover 34 is equipped with a cleaning pipe with spray holes 35.

[0036] Workflow: The control system starts, the feeding unit 2 feeds in soybeans, the metering pump 194 starts supplying water, the motor 12 drives the grinding unit 1 to work, the pressure compensation device automatically maintains the grinding pressure, the produced soy milk is filtered and collected, the concentration is controlled by the soy milk concentration monitor 33 and pumped out by the gear pump 321, the produced pulp residue is automatically sent out by the spiral fan integrated machine 4, after production is completed, the automatic cleaning unit starts, and the inside of the grinding machine is cleaned through the first water spray nozzle 31 and the water spray hole 35.
