Preparation device of high-strength and low-gas-forming-amount silica sand

Abstract

The invention discloses a high-strength low-gas-forming-amount silica sand preparation device and relates to the technical field of silica sand preparation, the high-strength low-gas-forming-amount silica sand preparation device comprises a box body, a circular ring frame, a feeding frame, an opening and closing door and supporting legs, the top of the box body communicates with the feeding frame, the circular ring frame is arranged on the outer surface of the box body, and the opening and closing door is hinged to the front face of the circular ring frame; supporting legs are arranged at the bottom of the box body, a motor is arranged at the bottom of the box body, and the box body comprises a screen, a bent rod, an arc rod, a stirring rod, a rotating rod and a valve. Silica sand can make contact with the top of cement after being screened by the screen, the stirring rod can stir the cement through the rotating rod, and when the stirring rod rotates, a sliding plate can rotate in a groove rotating disc; the groove rotating disc drives the arc rod to rotate and stir in the cement through friction of the sliding plate, and the arc rod and the stirring rod stir the cement and the silica sand through different rotating directions, so that the silica sand and the cement can be fully mixed together.

Description

technical field [0001] The invention belongs to the technical field of silica sand preparation, in particular to a preparation device of high-strength and low-gas generation silica sand. Background technique [0002] Natural silica sand resources are abundant, such as aeolian sand, river sand and sea sand, etc., and the price is low. Prepare in advance before use, the size and specification of the silica sand itself is different, the silica sand needs to be sieved during the preparation, and when the silica sand is sieved through the screen, the silica sand that cannot be sieved will affect the efficiency of the screen, so We propose a device for preparing high-strength and low-gas-forming silica sand. Contents of the invention [0003] The object of the present invention is to provide a preparation device for high-strength and low-gas generation silica sand. When the screen screen screens the silica sand through the vibrating mechanism, the round rod will expand on the s...

Problems solved by technology

[0003] The object of the present invention is to provide a preparation device for high-strength and low-gas generation silica sand. When the screen screen screens the silica sand through the vibrating mechanism, the round rod will expand on the surface of the screen screen through the extrusion of the screen screen. When expanding, it will push the silica sand inside the screen to move to increase the screening efficiency of the screen and solve the existing problems
