Description

A garbage drum screening device

technical field

The utility model relates to a drum screening device for garbage screening.

Background technique

Since the components of municipal solid waste are composed of complex plastics, papers, fabrics, etc., the traditional drum screen has problems such as easy blockage of the screen and low screening efficiency, and when the straight cylindrical drum is tilted, the material is affected by gravity in the drum. Falling too fast can easily lead to incomplete separation of garbage.

Utility model content

The technical problem mainly solved by the utility model is to provide a frustum-conical drum screen with simple structure, low cost and good separation effect.

In order to solve the above technical problems, the technical solution provided by the utility model is: a garbage drum screening device, including a feed port (1), a drum (2), a rotating shaft (3), an arc-shaped paddle (4), Fine material outlet (5), coarse material outlet (6), machine base (7), drum driving device (8) and rotating shaft driving device (9), and the described feed inlet (1) is connected on the machine base (7) , the outside of the drum (2) is wrapped with a screen, the drum (2) is connected to the shaft (3) on the central axis through a bracket, and the shaft (3) is installed obliquely on the base (7), so The rotating shaft (3) is fixedly connected with two evenly distributed arc-shaped paddles (4) along the circumferential direction, and the arc-shaped paddles (4) are helically arranged along the axial direction of the rotating shaft (3). The top of the arc-shaped paddle (4) is adapted to the shape of the inner wall of the drum (2), the end of the rotating shaft (3) is connected to the rotating shaft driving device (9), and the drum (2) is connected to a The drum driving device (8), the fine material outlet (5) and the coarse material outlet (6) are fixed in the middle and rear of the machine base (7) respectively.

Further, the drum (2) is a truncated cone, and the cone angle of the truncated cone is 15-40°.

Further, the arc-shaped blade (4) gradually becomes thinner from the blade root to the blade tip, and the distance between the top of the blade tip and the inner wall of the drum (2) is 5-10 mm.

The beneficial effects of the utility model: through the special arrangement of the blades on the rotating shaft, and the blades are not in contact with the inner wall of the drum, material adhesion and blockage are avoided; the shape of the arc-shaped blades gradually becomes thinner from the blade root to the blade tip, The strength and service life of the blades are guaranteed, and the drum adopts the shape of a truncated cone, which reduces the speed of materials moving down in the drum and improves the screening efficiency at the same time.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present utility model, the following embodiments are listed hereby, and detailed descriptions are as follows in conjunction with the accompanying drawings:

See Figure 1 and Figure 2: a garbage drum screening device, the garbage enters from the feed port 1, the rotating shaft driving device 9 drives the rotating shaft 3 to rotate clockwise, and the arc-shaped paddle 4 fixed on the rotating shaft 3 beats the garbage Crushed, the garbage falls inside the screen of the drum 2, and the drum 2 rotates under the drive of the drum driving device 8, and the garbage is screened into oversize and undersize, and the undersize is discharged from the fine material outlet 5 at the bottom of the machine base 7 , the sieve is discharged from the coarse material outlet 6 at the rear of the machine base, and the arc-shaped paddles 4 are arranged in a spiral along the axial direction of the rotating shaft 3, which is conducive to the transportation and crushing of garbage. The shape of the inner wall is adapted to effectively screen the rubbish in the drum 2 while preventing the screen from clogging.

Although the preferred embodiment of the utility model has been described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative, not restrictive, and those skilled in the art Under the enlightenment of the utility model, those skilled in the art can also make many forms without departing from the purpose of the utility model and the protection scope of the claims, and these all belong to the protection scope of the utility model.
