Description

Rotary Garbage Desilter

technical field

The invention relates to the field of garbage treatment equipment, in particular to a rotary garbage desilter.

Background technique

Construction waste resource treatment is to process construction waste into raw materials needed for building materials. The raw materials of cement-based building materials are roughly divided into three categories: coarse aggregate, fine aggregate, and powder. Since waste and old fired clay bricks are the dominant material of construction waste in my country, the utilization value of raw materials after resource treatment of construction waste is higher and the use is wider. However, due to the low strength of the mud powder in the construction waste, there are defects such as falling corners in the clay brick after sintering, which affects the use of the clay brick.

To remove the mud powder in the construction waste, the market usually has: linear sieve, vibrating sieve. These equipments are common equipment for mining machinery, and the construction waste is mixed, miscellaneous and wet, so there are special requirements for the desilting of construction waste, and the above-mentioned equipment is not suitable for processing mud powder in construction waste. The mud powder in the construction waste treated by the linear sieve is miscellaneous and wet, which often blocks the filter screen of the linear sieve, which reduces the processing capacity of the construction waste. The vibrating screen generally separates materials with relatively large particles. For the fine mud powder in the construction waste materials are not applicable. After research and analysis, using the principles of conveying, separation, and cleaning, we specially develop desilting equipment that meets the requirements of removing mud powder from construction waste.

The ideal goal of the equipment for removing mud powder from construction waste is: relatively low production energy consumption, relatively high production efficiency, good mud removal effect, and can meet the characteristics of mixed, miscellaneous, and wet construction waste.

Contents of the invention

The object of the present invention is to provide a rotary garbage desilter with high efficiency, low energy consumption and good desilting effect.

The technical solution to achieve the above purpose is: rotary garbage desilter, characterized in that it includes a frame and a drum mounted on the frame that rotates along the horizontal direction, one end of the drum is connected with a power mechanism that drives the drum to rotate, and the two ends of the drum Both ends are open as the feeding port and the discharging port, the inside of the drum is equipped with helical blades along the axial direction, the wall of the drum is provided with mud powder discharge slots along the axial direction and evenly along the axial direction, and the outside of the drum is equipped with a filter. net.

The circumference of one end of the drum is provided with a plurality of supporting rollers, and the supporting rollers are installed on the frame through a roller frame, and the other end of the drum is installed on the frame through a slewing support.

The power mechanism includes a motor and a large gear arranged at one end of the drum, the output end of the motor is connected with a pinion, and the large gear is connected to the pinion in transmission.

The outside of the drum is provided with a compressed air pipe parallel to the axial center of the drum. The compressed air pipe is installed on the frame through a bracket. The compressed air pipe is evenly distributed with spray holes, and nozzles are installed on the spray holes. The outlet of the nozzle end toward the filter.

The outer side of the cylinder is also provided with a nylon brush, which is installed on the frame through the brush holder, and the nylon brush is set in contact with the filter screen.

The left and right ends, the front and rear ends and the upper end of the frame are all provided with sealing plates to seal, and the feed inlet and the discharge port of the drum protrude outward respectively from the left and right ends of the sealing plates, and the bottom of the drum is provided with a large mouth end upward. The cone bucket is installed on the frame.

Beneficial effects of the present invention:

1. High production efficiency

The invention adopts rotary filter, and is equipped with nylon brush and compressed air blowing, so that the filter screen is not easy to be blocked, and the filter efficiency is improved, so the production efficiency is high.

2. Low energy consumption

The comprehensive energy consumption of the present invention is 18KW/t-22KW/t, while the comprehensive energy consumption of the linear screen (driven by four motors and not blocked) is 30KW/t-40KW/t, and the energy saving is increased by one to two times.

3. Good mud removal effect

Because the present invention is not easy to block, the mud removal rate reaches over 98%.

4. Investment saving

The present invention is driven by a single motor reducer, and does not need to be equipped with a shock absorber, while the linear screen must be equipped with at least 4 motor reducers, and also needs an eccentric device, a shock absorber, etc., thus saving investment.

5. Low noise during production

The invention rotates smoothly and has no obvious noise, while the linear sieve needs to use an eccentric device to remove mud, and the vibration is large and the noise generated is large.
