Description

Screening machine

technical field

The utility model relates to a slag screening device, in particular to a slag screening machine.

Background technique

With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount of construction waste in China has accounted for more than 1/3 of the total urban waste. Waste partition boards, residual boards and other garbage in construction waste need to be broken into small particles in the later stage. After crushing, the small particles are screened by the slag screening machine, and the particles that meet the standards are reused. The existing slag screening machine has a low degree of automation, requires frequent feeding, low screening efficiency, and serious dust pollution. Moreover, the existing slag screening machine cannot be used in conjunction with other equipment such as crushers, resulting in the transportation between the crusher and the slag screening machine. The equipment needs to be moved frequently during material handling.

Utility model content

The purpose of the utility model is to overcome the problems of low automation, frequent feeding, low screening efficiency and serious dust pollution of the current slag screening machine, and provide a slag screening machine. The hopper stores materials and materials, and can control the output speed; the degree of automation is high, and it can be used together with the crusher through the conveyor belt. The screening efficiency is high, the noise is low, and dust pollution can be reduced.

The utility model is realized in the following way: a slag screening machine includes a frame on which a trommel assembly and a feeding assembly are arranged, the trommel assembly includes a main shaft and a fixed steel ring, and the inner side of the fixed steel ring is arranged There is a screen, the main shaft is inclined, and the main shaft is connected to the geared motor. The feeding assembly includes a hopper, a hopper and a vibration motor. The hopper is set at the lower end of the silo, and the end of the hopper extends into the screen. There is a baffle plate capable of changing the size of the feeding port, a conveyor belt is provided at the lower part of the trommel screen, and a discharge port is provided at the end of the trommel screen.

In the above-mentioned slag screening machine, the inclination angle of the main shaft is 10-30 degrees.

In the above-mentioned slag screening machine, the hopper is provided with a motor base, and the vibration motor is installed on the motor base.

In the above-mentioned slag screening machine, the higher end of the screen is connected to the hopper, and the lower end of the screen is installed with a discharge port.

In the above-mentioned slag screening machine, a sprayer is arranged in the screen.

The utility model has the following advantages: the slag screening machine of the utility model has a large silo volume, saves feeding time, has an exciting device, prevents the material from being stored in the hopper, and the flow rate is adjustable, and the hopper door can be opened and closed selectively. The size can control the discharge speed; the degree of automation is high, and it can be used together with the crusher through the conveyor belt, and the screening efficiency is high. No vibration, low noise, equipped with a spray dust removal device, which can reduce dust and facilitate movement.

Detailed ways

Below in conjunction with specific embodiment the utility model is further described.

Embodiment 1: A kind of slag screening machine, including a frame 1, on which a trommel assembly and a feeding assembly are arranged, the trommel assembly includes a main shaft 2 and a fixed steel ring 3, the main shaft is inclined, and the fixed steel ring 3 Installed on the main shaft 2 through the connecting rod to form a cylindrical drum screen, the inclination angle of the main shaft 2 is 10-30 degrees, preferably, the inclination angle of the main shaft is 20 degrees, the main shaft 2 is connected with the geared motor 4 through a coupling, fixed A screen 4 is arranged inside the steel ring. Driven by the motor, with the rotation of the main shaft, the screen screens out materials that meet the particle size; the feeding assembly includes a silo 6, a hopper 7 and a vibrating motor 8. Temporarily stored in the hopper of the slag screening machine, the hopper 7 is arranged at the lower end of the hopper 6, and the end of the hopper 7 extends into the screen, and the hopper 7 is provided with a baffle 9 that can change the size of the feed port, and the baffle 9 can be changed by rotation. The position of the plate 9, so as to control the feeding speed, the hopper 7 is provided with a motor base 12, the vibration motor 8 is installed on the motor base 12, the raw material flows into the drum screen through its own gravity and the excitation force of the vibration motor 8, A sprayer 13 is arranged in the screen 4, and the sprayer starts to spray water mist to achieve the effect of dust reduction. The lower part of the trommel is provided with a conveyor belt 10, the higher end of the screen is connected to the hopper 7, and the lower end of the screen is installed with a discharge port 11. After the materials with small particle size are screened by the screen, they fall onto the conveyor belt 10 and are taken to the designated location for storage. The materials with large particle size are discharged to the conveying device outside the drum screen through the discharge port 11, and can be directly transported through the conveying device. It is connected with the crusher feeding hopper and enters the crusher for secondary crushing.
