[0008] A mixing device for preparing solid waste-based cementitious materials, including a mixing device. The mixing device is composed of a support frame, a plurality of storage bins, a feeding mechanism, and a mixing tank. The plurality of storage bins are installed at the upper end position of the support frame. A cover is installed at the upper feeding port position of the storage bin. A weighing mechanism is installed around the bottom end of the storage bin. The bottom end of the weighing mechanism is installed at the upper end position of the support frame.

The feeding mechanism is installed on the upper side of the support frame. The mixing tank is installed on one side of the feeding mechanism. An outlet pipe is installed at the bottom end position of the mixing tank. A stirring mechanism is installed inside the mixing tank.

[0009] Optionally, the stirring mechanism is composed of a shaft rod, stirring blades and a first power mechanism. The shaft rod is rotatably installed inside the mixing tank.

[0011] Optionally, the quantitative discharging mechanism is composed of a discharging spiral rod and a third power mechanism. The bottom end of the discharging spiral rod extends into the inner part of the material guiding pipe.

The third power mechanism is installed at the upper side position of the storage bin.

[0012] Optionally, the feeding mechanism is composed of a feeding spiral rod, a feeding cylinder and a second power mechanism.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0016] 1. During the feeding process, multiple storage bins can be used simultaneously for feeding at the same time, or feeding can be carried out in stages according to usage requirements. During feeding, through the combined use of the quantitative discharging mechanism and the weighing mechanism, quantitative feeding can be achieved, which is convenient for quickly and accurately feeding the inside of the mixing tank.

[0017] When the feeding mechanism is in use, after the materials in the storage bin are introduced into the feeding mechanism, the second power mechanism drives the feeding spiral rod to rotate. The materials are pushed forward by the feeding spiral rod, and the materials are introduced into the mixing tank through the feeding cylinder.

[0018] When in use, the quantitative export mechanism drives the export screw rod to rotate through the third power mechanism. When the export screw rod rotates, the blades push the material forward along the material guide pipe during rotation. By adjusting the rotation speed of the third power mechanism or changing the parameters of the blades, the conveying volume of the material can be accurately controlled, thus achieving the effect of quantitative output.

[0019] When in use, the weighing mechanism weighs the weight of the storage bin through the pressure sensor, and can monitor the material weight inside the storage bin in real time, so as to understand the discharge volume. When the discharge volume reaches the set weight, the controller can control the quantitative export mechanism to stop running, which is convenient for quantitative feeding.
