Description

Professional treatment of municipal solid waste grading sieve

technical field

The utility model belongs to the field of vibrating screening machinery, and mainly relates to a grading sieve for professionally treating urban living garbage that can effectively process urban living garbage.

Background technique

The consistent screening of MSW is a difficult problem, because the composition of MSW is very complex, not only the types are complex, but also the shape is also very complex, including organic waste, inorganic waste and sand and gravel waste. Existing elastic bar bar screens have good effects in processing sticky and wet materials in industries such as metallurgy and mining. However, due to the characteristics of the elastic rods, the length of the rods is very short and there are many supporting beams, it is easy to cause material accumulation when processing municipal solid waste, especially materials such as plastics, thereby causing material blockage, and the elastic rods are also easy to break.

Contents of the invention

The purpose of the utility model is to provide a grading sieve for professional treatment of municipal solid waste. The grading sieve has significant progress in reducing the resistance of materials, effectively loosening domestic waste and increasing structural strength.

The utility model is realized through the following measures, including a sieve box, a sieve plate, a vibrator, a vibration damping device, a power transmission device and a support leg, and is characterized in that: the sieve plate is a rod sieve plate, and the overall sieve surface is composed of Composed of two sections of bar sieve plates, the two sections of bar sieve plates are arranged front and back, and are in a stepped shape; the inclination angle α of the screen surface is 25°~30°; the bars of each section of bar sieve plates are welded together with the vertical plate, and It is installed on the sieve plate bracket through the seat plate; the distance between the rods on the sieve plate can be adjusted.

The damping device is composed of a metal helical spring, and a limited rubber band is connected between the upper and lower spring seats of the spring. The bars of the bar sieve plate are seamless steel pipes.

The beneficial effect of the utility model is that the screen surface of the two-section rod sieve can increase the step height of the upper and lower two-section sieve plates in a limited space, which is beneficial to disperse the garbage, and also reduces the beams supporting the rods and reduces the waste materials. resistance. The rod is structurally supported by welding a vertical plate under the round tube, which greatly improves the structural strength of the rod. At the same time, garbage such as plastics can easily pass through, or slide off the sieve. Because the height between the bar and the lower beam is large enough, the inclination angle of the screen surface is large enough, the flow speed of the garbage is accelerated, and it is not easy for the material to be blocked when it falls from the screen. It has the characteristics of reasonable structure, long service life, large processing capacity and high screening efficiency, and is suitable for the classified treatment of municipal solid waste in large and medium-sized cities.
