Commonly used mortars include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar.

[0003] In the prior art, a powder mixing device for waterproof mortar disclosed in a Chinese patent with the publication number CN205435601U has a simple structure. While the cylinder rotates by itself to drive the powder to rotate fully, the stirring shaft drives the stirring paddle to rotate in the opposite direction, preventing the powder from piling up. Moreover, there are stirring blades on the inner wall of the cylinder to make the mixing of various powders uniform.

[0004] However, in the prior art, some lumps will be mixed in the raw materials of waterproof mortar, and it needs to be screened before mixing, otherwise it will affect the product quality. And the above prior art only mixes by stirring and cannot mix efficiently. Summary of the Utility Model

Multiple raw material transfer tanks are connected to the top of the preliminary mixing tank. A pneumatic separation mixing component is provided at the bottom of the preliminary mixing tank. A transfer and screening component is provided at the top of the preliminary mixing tank, and the transfer and screening component is connected to a secondary mixing component.

[0008] Further, the pneumatic separation mixing component includes a high-pressure blower and a diverter. The high-pressure blower is fixedly arranged at the bottom of the preliminary mixing tank. The diverter is connected to the high-pressure blower and arranged at the bottom inside the preliminary mixing tank. The diverter is provided with air holes.

[0009] Further, the transfer and screening component includes a connecting pipe and an exhaust fan. The connecting pipe is connected to the top of the preliminary mixing tank, and the exhaust fan is installed on the connecting pipe and penetrates through the connecting pipe.

[0010] Further, a protective cover is installed on the diverter, and a filter screen is installed on the exhaust fan.

[0011] Further, the secondary mixing assembly includes a secondary mixing tank, a stirring motor, and a spiral lifting stirrer. The secondary mixing tank is connected to the connecting pipe. The stirring motor is fixed inside the secondary mixing tank. The spiral lifting stirrer is arranged on the output shaft of the stirring motor, and the spiral lifting stirrer is arranged in a spiral shape.

[0012] Further, the secondary mixing assembly is inclined, with the section with the stirring motor being relatively lower and the section connected to the connecting pipe being relatively higher.

[0013] Further, the spiral lifting stirrer is arranged in a spiral shape and has a gap with the inner wall of the secondary mixing tank.

[0014] Further, the secondary mixing tank includes an upper tank and a lower tank. The upper tank is connected to the connecting pipe, and the lower tank is fixedly bolted to the upper tank.

[0015] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0016] By arranging the air separation and mixing assembly in the preliminary mixing tank to dry and crush the agglomerates, and at the same time mix the small particles entering the preliminary mixing tank and make them enter the secondary mixing assembly under the action for re - mixing, the mixing efficiency is improved.
