technical field

The utility model relates to a screening device, in particular to a screening device applied to construction waste treatment.

Background technique

At present, in the domestic construction waste treatment process, the small pieces of material produced after crushing materials are mainly screened through vibrating screens. The sundries in the construction waste are easy to block the screen, resulting in reduced screening efficiency and difficult to clean. In addition, the crushed recycled aggregates from construction waste are prone to cracks, dark spots, and sharp edges and corners, resulting in low-quality aggregates that are difficult to use.

Detailed ways

Example 1.

The construction waste shaping and screening device described in the utility model, the screen cylinder 2 is fixedly arranged on the bracket 1 and the motor 3 is electrically connected with the screen cylinder 2, and the screen cylinder 2 is divided into three sections, which are successively the feed section screen cylinder 4, Shaping section 5 and discharge section sieve cylinder 6, described shaping section 5 is a cylindrical shell, wherein the sieve hole diameter of feed section sieve cylinder 4 is smaller than the sieve hole diameter of discharge section sieve cylinder 6, the utility model preferably enters The sieve diameter of the sieve drum 4 in the feeding section is 3-10mm; the sieve diameter of the sieve drum 4 in the feeding section is 20-40mm. In this embodiment, it is preferred that the sieve diameter of the sieve cylinder 4 in the feed section is 5 mm, and the sieve diameter of the sieve cylinder 6 in the discharge section is 30 mm.

In this embodiment, the sieve cylinder 2 is divided into three sections, and the material enters from the sieve cylinder 4 of the feed section. Since the sieve cylinder 4 of the feed section has a smaller sieve hole, finer impurities such as dust, sand, and soil can be screened out to reduce the material in the shaping process. The dust generated by the sieve drum 6 in the discharge section and the discharge section; then enters the shaping section 5 for beating, on the one hand, the materials containing hidden wounds and cracks can be fully broken, and on the other hand, the sharp edges and corners can be removed through mutual friction between materials; After passing through the sieve drum 6 in the discharge section, it is screened again and then output to fully separate the dust and materials.

Example 2.

This embodiment is basically the same as Embodiment 1, except that the inner walls of the screen cylinder 4 of the feed section and the screen cylinder 6 of the discharge section are respectively provided with spiral protrusions 7, and the spiral protrusions 7 are made of high manganese steel material.

The spiral protrusion 7 described in this embodiment can push the material to move forward continuously in the screen drum 2 .

Example 3.

This embodiment is basically the same as Embodiment 1 or 2, except that several types of L-shaped lifting plates 8 are uniformly arranged on the inner wall of the screen cylinder 4 in the feed section, the shaping section 5 and the screen cylinder 6 in the discharge section. The L-shaped lifting plate 8 is made of high manganese steel.

The lifting plate described in this embodiment, when the screen cylinder 2 rotates, picks up the material from the bottom of the screen cylinder 2 and throws it down from a high place, so that the material with hidden damage and cracks is fully broken, and at the same time due to the presence of some plastic in the construction waste Light objects such as heavy cement blocks will fall first, and light objects such as plastics will float up and fall slowly. The blocked sieve holes in the screen can be continuously thrown up and beaten by heavy cement blocks and other materials. In the process of dredging, the efficiency of screening is improved.

Example 4.

This embodiment is basically the same as Embodiment 1 or 2 or 3, except that the angle between the central axis of the sieve cylinder 2 and the horizontal line is 5°-7°, and the central axis of the sieve cylinder 2 is preferred in this embodiment The angle with the horizontal is 7°.

The included angle is formed between the screen cylinder 2 and the horizontal plane in this embodiment, so that when the materials rotate in the screen cylinder 2, they can fully rub against each other through the action of gravity, and effectively remove sharp edges and corners on the materials.

Example 5.

This embodiment is basically the same as Embodiment 1 or 2 or 3 or 4, except that a sealing cover 9 is provided outside the screen drum 2 .

In this embodiment, a sealing cover 9 is provided outside the sieve cylinder 2, which can effectively prevent the dust generated by screening from diffusing into the atmosphere and reduce the pollution to the environment.
