Description

Screening machine

Technical Field

The utility model discloses be applied to industrial field, specifically be a screening machine.

Background

Screening machines (powder sifters) utilize the relative motion of bulk materials and sieve surfaces to make partial particles penetrate through sieve pores, and divide materials such as sand, gravel and broken stone into vibrating screening mechanical equipment with different grades according to particle sizes. The particle grade of the screening is determined by the screen surface, which is divided into three types of grate, plate screen and mesh screen. The grate is suitable for screening large-particle materials, and gaps of the grate are 1.1-1.2 times of the particle size of undersize materials and are generally not suitable to be smaller than 50 mm. The plate screen is formed by punching a steel plate, holes are circular, square or rectangular, the aperture is generally 10-80 mm, the service life is long, the plate screen is not easy to block, and the plate screen is suitable for screening medium particles. The mesh screen is woven or welded by the steel wire, and the hole is square, rectangle or rectangular shape, and the aperture is generally 6 ~ 85 millimeters commonly used, and rectangular shape sieve mesh is suitable for screening moist material, and the advantage of mesh screen is that effective area is great. The screening machine is divided into rolling screening and vibrating screening. The rolling screening includes sieve shaft type screening machines, drum screens, solid and spiral roller screens, blade type roller screens and the like, and the vibration screening basically comprises banana screens, high clothes screens, relaxation screens and the like. The rolling type screening principle equipment adopts forced conveying, so that materials are not easy to block a screen surface. The vibrating type is easy to cause blockage due to the principle characteristic of screening sticky and wet materials (generally, the moisture content is more than 6%), and the power is higher. The conventional drum screening machine cannot realize grading screening.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Referring to fig. 1, the present invention provides a technical solution: the screening machine comprises a base 12, wherein a hydraulic cylinder 8 is arranged on the base 12, an end-to-end connecting support plate 10 of the hydraulic cylinder 8 is arranged, a reset spring 11 is arranged between the support plate 10 and the base 12, a classifying basket 9 is arranged above the support plate 10, a first discharge hole 7 is arranged on the classifying basket 9, a second discharge hole 5 is arranged on the other side of the first discharge hole 7, a rotary drum 4 is arranged above the classifying basket 9, a screen 6 is arranged on the rotary drum 4, a driven wheel 1 is arranged at one end of the rotary drum 4, the driven wheel 1 is connected with a driving wheel 3 through a belt 2, and the driving wheel 3 is connected to a transmission shaft of a motor 13.

In particular, the hydraulic cylinder 8 can be replaced by an automatic telescopic rod.
