When the diesel engine is driven, the device comprises a reduction gearbox connected with a power output shaft of the diesel engine; when the power system 2 is a motor under the condition of satisfying the power, the power system comprises a speed reducer connected with a power output shaft of the motor.

The left side of the middle part of the frame body 1 is provided with a receiving bin 3 with a large-upper-part and small-lower-part funnel type structure, and the receiving bin 3 with the funnel type structure is beneficial to receiving small-particle-size materials falling from the upper screen 51; the material discharged by the collecting bin 3 is favorably and intensively closed and discharged. The shell material of the funnel type structure is the receiving bin 3 which is made of metal plates in a sealing welding mode and is of a square funnel type structure in a overlooking mode, and therefore welding and fixing of the receiving bin 3 on the middle layer of the frame body 1 are facilitated.

For the compact design of the beneficial structure: a fine crusher 4 is arranged on the right side of the middle part of the frame body 1, and the fine crusher 4 is used for performing fine crushing treatment on materials; the vibrating screen 5 is arranged above the material collecting bin 3, and the vibrating screen 5 with a dustpan type structure is obliquely arranged at the top of the frame body 1 towards the lower right to vibrate, crush, filter and screen large blocks of dried and dehydrated sludge materials.

It should be noted that the term "shake" as used herein includes both "shake" and "shake". The specific actions of the vibrating mechanism of the vibrating screen 5 include two actions of "shaking up and down" and "shaking left and right".

A conveyor 6 is arranged above the high position at the left side of the vibrating screen 5 and is used for containing materials conveyed from low to high by the conveyor 6. Note that the conveyor 6 here is a belt conveyor having a steep slope. The device is mainly used for transferring and conveying the materials (dried and dehydrated sludge) at the lower part of the bracket 1 to the upper part of the left side elevation point of the vibrating screen 5 (shown in figure 1) at the higher part of the bracket 1.

As another most critical innovation of the present invention: the lower bottom surface of the vibrating screen 5 is provided with a screen 51 which is in butt joint with a baffle 52 at the lowest position to stop the material and form a residue outlet 53 on the vertical side wall at the lowest position of the slope surface of the vibrating screen 5. It should be noted that: the screen mesh is used for filtering and screening the shattered materials in cooperation with the ' shaking ' (up-and-down shaking ' and ' left-and-right shaking ') action of the vibrating screen 5. The upper end surface of the screen 51 is fixedly provided with a plurality of baffles 52 (shown in figure 2) which are uniformly inclined downwards in the transverse direction and have gradually increased lengths. The baffle plate 52 is a vertically arranged metal plate, and the bottom end of the metal plate can be fixedly connected with the screen 51 into a whole by welding; baffle 52 is as shown in fig. 2, from last to horizontal length ladder when increasing progressively, still unify towards one side slope, specifically unify towards the slope (as in fig. 2) that is equipped with slag outlet 53, so that the major gravity metal material is blocked by baffle 52 and prevents the metal to cross the time, constantly downwards the landing and is blocked by baffle 52 and connects greatly, until the landing to the domatic lowest department of screen cloth 51 horizontal longest and with the lowest department of baffle 52 of slag outlet 53 butt joint, and from domatic lowest department baffle 52 left side vertical side wall with slag outlet 53 sealed weld even butt joint slag outlet 53 department to the equipment material of giving first place to the surplus slag metal of discharging outward. And finishing the sorting of most metals. Meanwhile, the baffle plates 52 with the gradually increased transverse lengths have a slow descending effect on the materials so as to prolong the retention time of the materials on the vibrating screen 5, so that the materials are vibrated for multiple times and shattered for multiple times, and the exposed metals are fully stripped. Moreover, the baffle plates 52 with the gradually increased transverse length have the vertical height which can effectively block the metal materials with large specific gravity and easy sinking, so that the metal materials can be discharged from the residue outlet 53; on the other hand, the dewatered sludge material with lighter specific gravity can cross the baffle plate 52 to slide continuously downwards along the slope once shaking up and down and left and right along with the vibrating screen, and finally falls into the fine crusher below.

In addition, the lower part of the lowest part of the slope surface of the screen 51 is used for feeding materials to a feeding port at the upper end of the fine crusher 4. The fine crusher 4 is used for finely crushing the unfiltered dewatered sludge and extremely small amount of metal materials which have light specific gravity and are easy to lift. The discharging hopper 41 at the bottom of the fine crusher 4 avoids the power system 2 and discharges materials obliquely towards the outside of the lower right of the frame body 1. The lower hopper 41 is welded with metal plates to form a material guiding structure, and as shown in fig. 1, discharges the finely-divided materials toward the outside of the right side of the frame body 1.

The working principle of the utility model is as follows: the lump materials are shattered by the vibrating screen 5, and meanwhile, the materials with the diameter smaller than the mesh diameter of the screen 51 fall into the receiving bin 3 below, and are discharged from the feed opening 31 with the small diameter at the bottom of the receiving bin 3; the other part of the materials are in vibration action combined with the up-down and left-right shaking of the vibrating screen, the specific gravity of the materials containing metal and metals is different, the materials with large specific gravity containing metal impurities (such as floccule wrapping) are always sunk to the bottom and are not easy to cross the baffle plate, the materials are blocked by the baffle plate 52, and finally the materials are discharged from a residue outlet 53 which is in butt joint with the baffle plate 52 at the lowest position. The other part of the dewatered sludge particles or the small pieces of crushed materials with the specific gravity lower than that of the metal are lifted to a higher height, so the dewatered sludge particles or the small pieces of crushed materials can pass through the baffle 52 more easily and continuously slide down along the slope surface until the dewatered sludge particles or the small pieces of crushed materials enter the fine crusher 4 with an upper opening at the lower part for fine crushing treatment. In the process, the vibrating screen 5 vibrates up and down, left and right, so that the large materials can be vibrated and crushed, metal in the large materials is stripped while the large materials are vibrated and crushed, and the materials can be more fully vibrated and crushed for multiple times along with the slow descending action of the baffle plate 52 on the materials; the metal sorting and picking-up are more facilitated. The material filtered by the screen 51 enters a material receiving bin to be collected and discharged; and (4) feeding the unfiltered material into a fine crusher for fine crushing and crushing treatment and blanking. The discharged materials can be respectively butted with a conveyor, and transferred to an aging chamber through the conveyor for aging and stacking.

In the above embodiment: the power system 2 is provided with a double-output-shaft speed reducer 22 connected with the output shaft of the power source 21; the first power output of the double output shaft speed reducer 22 drives the vibrating mechanism of the vibrating screen 5 to operate through belt transmission, and the second power output of the double output shaft speed reducer 22 drives the fine crusher rotor of the fine crusher 4 to operate through belt transmission.

It can be seen that, a set of power system 2 is adopted to drive the vibrating mechanism of the vibrating screen 5 and the fine crusher rotor of the fine crusher 4 to operate through transmission mechanisms such as belt transmission and the like, and the set of power system 2 can be directly installed on the right side of the bottom of the frame body 1 and below the fine crusher 4, so that the device is compact in overall structure and is very suitable for being used in small-site space plants. In this case, the power system 2 preferably includes a motor and a speed reducer connected to a power output shaft of the motor; the speed reducer is a double-output-shaft speed reducer so as to drive the vibration mechanism to operate and drive the fine crusher to operate. In addition, when more power is needed, the electric motor can be replaced by a diesel engine, and the speed reducer can be replaced by a gearbox with double output shafts. The power of the motor or the diesel engine is determined according to the power of the fine crusher and the design of parameters of the vibrating screen.

A power source 21 such as a driving motor drives a double-output-shaft speed reducer 22 to rotate; the double-output-shaft reducer 22 drives the power output shaft of the hard tooth surface reducer 14 to rotate at a lower speed; thereby driving the rocker arm wheel 7 to rotate at a lower speed; in contrast, the double-output-shaft speed reducer 22 drives the belt wheel of the fine crusher outside the rotor of the fine crusher 4 to rotate at a higher speed through belt transmission, and the dewatered sludge is very easy to finely crush and is also very easy to shatter due to vibration because the moisture content of the dewatered sludge is low. The fine crushing effect of the fine crusher 4 after being decelerated should not be questioned, and the fine crushing treatment of the dewatered sludge is not affected even if the rotating speed is low.
