[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 6 This utility model provides a pre-grinding proportioning and supply device for waste residue-geolithic aerated mixed soil, the device comprising:

[0028] Mounting frame 1, and a plunger pump 2 and a feed pipe 3 mounted on the mounting frame 1, with a CNC box 4 mounted on the top of the feed pipe 3;

[0029] The screw conveyor 5, used for conveying waste residue, is installed in the conveying cavity of the feed pipe 3. The top end of the feed pipe 3 is equipped with a feed pipe 6 that communicates with the conveying cavity. A metering component 7 is installed in the feed pipe 6. The metering component 7 includes a support shaft 71 that is rotatably installed in the feed pipe 6. A support plate 72 is installed on the support shaft 71. Pressure sensors 73 are embedded in the four corners of one end of the support plate 72. A carrying plate 74 is installed on the top end of the pressure sensor 73. A rotary motor 75 for driving the support shaft 71 to rotate is installed on one side of the feed pipe 6. The rotary motor 75 and the pressure sensor 73 are electrically connected to the CNC box 4.

[0030] Abrasive mechanism 8, used for refining and grinding waste residue, is installed at the top of feed pipe 6.

[0031] The mounting bracket 1 is equipped with a servo motor 21 that drives the plunger pump 2 to rotate. The servo motor 21 is electrically connected to the CNC box 4. The outlet end of the plunger pump 2 is connected to a slurry supply pipe 22. The slurry supply pipe 22 is embedded with a flow meter that is electrically connected to the CNC box 4.

[0032] It should be noted that during use, the pre-screened waste residue is poured into the abrasive mechanism 8. After pre-grinding by the abrasive mechanism 8, it is introduced onto the carrier plate 74 through the feed pipe 6. The carrier plate 74 uses a pressure sensor 73 to weigh and measure the waste residue particles introduced onto the carrier plate 74. The weighing and measurement is set by the CNC box 4. When the set weight is reached, the rotary motor 75 is started to drive the support shaft 71 to rotate the support plate 72, which in turn drives the carrier plate 74 to flip, thereby pouring the measured waste residue into the conveying chamber of the feed pipe 3. The waste residue is automatically conveyed by the screw conveyor mechanism 5. Then, the liquid inlet end of the plunger pump 2 is connected to the well-stirred geopolymer slurry storage tank. In this way, the CNC box 4 controls the servo motor 21 to drive the plunger pump 2 to quantitatively supply the geopolymer slurry, thereby realizing automatic proportioning and feeding.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 6 The screw conveyor mechanism 5 includes a screw 51, which is rotatably installed in the conveying chamber of the feed pipe 3. One end of the feed pipe 3 is equipped with a power motor 52 that drives the screw 51 to rotate, and the power motor 52 is electrically connected to the CNC box 4.

[0034] It should be noted that the screw conveyor mechanism 5 uses a power motor 52 to drive the screw 51 to rotate, thereby automatically conveying the waste residue in the feed pipe 3.

[0035] In the embodiments of this utility model, please refer to Figures 1 to 6The abrasive mechanism 8 includes a connecting pipe 81, which is installed at the top of the feed pipe 6. A grinding funnel 82 is installed at the top of the connecting pipe 81. A support housing 83 is installed at the middle of the top of the connecting pipe 81. A drive motor 84 is installed inside the support housing 83. A grinding head 85 that cooperates with the grinding funnel 82 is rotatably installed at the top of the support housing 83. The bottom end of the grinding head 85 is fixedly connected to the output end of the drive motor 84. The drive motor 84 is electrically connected to the CNC box 4.

[0036] A feed trough 601 is also provided at the top of the feed pipe 6, and a lever 851 is symmetrically installed at the bottom of the grinding head 85;

[0037] It should be noted that when the abrasive mechanism 8 is in use, after the waste material is introduced into the grinding funnel 82, the drive motor 84 is started to drive the grinding head 85 to rotate, and then the grinding head 85 is used to grind the waste material in the grinding funnel 82 to refine the particles. The ground particles pass through the feed trough 601 of the feed pipe 6. When the grinding head 85 rotates, the lever 851 rotates synchronously, thereby sweeping the area above the feed trough 601, so that the waste particles can quickly enter the feed pipe 6.

[0038] In this embodiment: a hopper 86 is fixedly installed at the top of the grinding funnel 82. Crushing rollers 87 are symmetrically installed at the bottom of the hopper 86. A worm gear 88 is fixedly sleeved at one end of the drive shaft of the crushing roller 87 passing through the hopper 86. A worm 89 is rotatably installed on the outer wall of the hopper 86 at the middle of the two worm gears 88. The worm 89 meshes with both worm gears 88. A motor 9 for driving the worm 89 to rotate is installed on the outer wall of the hopper 86. The motor 9 is electrically connected to the CNC box 4. In this way, the hopper 86 is used to store waste residue raw materials. When material needs to be supplied, the motor 9 is started to drive the worm 89 to rotate. The worm 89 meshes with the two worm gears 88, thereby driving the two crushing rollers 87 to rotate. After the waste residue in the hopper 86 is initially crushed, it is poured into the grinding funnel 82. This crushing before grinding can improve the grinding quality of the waste residue.

[0039] The working principle of the pre-grinding proportioning and supply device for waste residue-geolith aerated mixed soil provided by this utility model is as follows:

[0040] In use, waste residue is poured into hopper 86, and then motor 9 is started to drive worm gear 89 to rotate. Worm gear 89 meshes with two worm wheels 88, thereby driving two crushing rollers 87 to rotate, initially crushing the waste residue in hopper 86 and then guiding it into grinding funnel 82. Then, drive motor 84 is started to drive grinding head 85 to rotate, and then grinding waste residue in grinding funnel 82 is carried out by grinding head 85 to refine the particles. The ground particles pass through feed chute 601 of feed pipe 6. When grinding head 85 rotates, lever 851 rotates synchronously, sweeping the area above feed chute 601, so that waste residue particles can quickly enter feed pipe 6 for pre-grinding. The waste residue particles are introduced into the carrier plate 74 through the feed pipe 6. The carrier plate 74 uses a pressure sensor 73 to weigh and measure the waste residue particles introduced into the carrier plate 74. The weighing and measurement is set by the CNC box 4. When the set weight is reached, the rotary motor 75 is started to drive the support shaft 71 to drive the support plate 72 to rotate, and drive the carrier plate 74 to flip, so that the measured waste residue is poured into the conveying chamber of the feed pipe 3. The waste residue is automatically conveyed by the screw conveyor mechanism 5. Then, the liquid inlet of the plunger pump 2 is connected to the well-stirred geopolymer slurry storage tank. In this way, the servo motor 21 controlled by the CNC box 4 drives the plunger pump 2 to supply the geopolymer slurry in a quantitative manner, thereby realizing automatic proportioning and feeding.

[0041] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
