Wet type sand screening machine for building

Abstract

The invention discloses a wet sand screening machine for construction, which comprises a base, a screening box, a feeding hopper and a bracket; a screening device is arranged in the screening box, and the sand screening device includes an outer installation frame and a screen in the horizontal direction And the sloping plates located at both ends of the screen, cams are installed under the screen; several water spray pipes are installed on the side wall of the screening box above the sand screening device; a horizontal drain pan is installed below the discharge port , a sink is fixed on the base below the drain pan. The present invention sprays water on the sand through the water spray pipe provided, so that the fine sand follows the water flow through the screen, improves the passing speed of the fine sand, adheres to the screen, improves the efficiency of blanking, and can adapt to dry sand and sand Wet sand is not affected by the external environment, ensuring the use of sand, internal water recycling, and the water in the fine sand is also convenient for the subsequent use of sand.

Description

technical field [0001] The invention relates to the construction field, in particular to a construction wet sand screening machine. Background technique [0002] Sand is an essential basic raw material in the field of modern construction. There are many impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades, and the use is different. The particle size of the sand required The grades are different. Therefore, it is necessary to sieve the sand before using it. The commonly used sand screening machine is to screen the sand through the screen, and the sand is often agglomerated after being exposed to the ground and dried. The sand is wet so that the sand sticks together, and the sand cannot fall smoothly on the screen, so the screening cannot be realized, which affects the use of the sand. The existing sand screening machine cannot solve the above problems. Therefore, it is necessary to design a sand screening mach...

The commonly used sand screening machine is to screen the sand through the screen, and the sand is often agglomerated after being exposed to the ground and dried. The sand is wet so that the sand sticks together, and the sand cannot fall smoothly on the screen, so the screening cannot be realized, which affects the use of the sand. The existing sand screening machine cannot solve the above problems. Therefore, it is necessary to design a sand screening machine to meet the requirements. above needs
