Sand and stone centrifugal screening equipment for constructional engineering

Abstract

The invention provides a sand and stone centrifugal screening equipment for constructional engineering. The sand and stone centrifugal screening equipment for constructional engineering comprises a rectangular hollowed-out rack capable of advancing, a separating device and a conveying device, wherein one end of the rack in the length direction is the front end in the advancing direction, the otherend of the rack in the length direction is the rear end in the advancing direction, the separating device is fixedly arranged on the upper end face of the rack and close to the front end of the rack,the conveying device is fixedly arranged on the upper end face of the rack and close to the rear end of the rack, the conveying device is used for supplying sand and stones to the separating device,the separating device is used for drying and centrifugally separating the sand and the stones, firstly discharging the sand outwards and then discharging the stones outwards, the separating device comprises a sieve tray with the tray bottom capable of being opened in an upward floating mode, the sieve tray is driven to rotate to screen out the sand and enable the sand to be discharged outwards, then the tray bottom of the sieve tray is opened to discharge the stones, and meanwhile, an air-drying mechanism and a heater can dry the sand-stone mixture. The sand and stone centrifugal screening equipment has the beneficial effect that the situation that the sand and the stones are difficult to separate due to moist caking is avoided.

Description

technical field [0001] The invention relates to the technical field of sand and stone separation, in particular to sand and stone centrifugal screening equipment for construction engineering. Background technique [0002] In the construction industry, the sand and gravel separation device is one of the equipment that is often used. The sand and gravel separation device is a kind of equipment that separates sand and gravel. With the development of science and technology, a variety of sand and gravel have appeared on the market separation device. After searching by the applicant, a Chinese utility model patent "a dust-free sand and gravel separator" was found. Its patent number is CN205613680U. On the left side of the outer casing, a drum is arranged inside the outer casing, barbed wire is arranged on the surface of the roller, a sand outlet is arranged on the surface of the outer casing, and the control panel is fixedly installed on the right side of the sand outlet. On the...

Problems solved by technology

The disadvantages are: 1. Most of the sand and gravel are outdoors, and the sand and gravel are easy to get wet and stick to each other, making it difficult to fully filter and separate the sand and gravel; 2. A large amount of sand will stick to the gravel, resulting in was
