Detailed Description

As shown in fig. 1, a vibrating automatic screening and deslagging device for kitchen waste comprises a vibrating screen 1 and a waste residue discharging screw conveyor 2. The vibrating screen 1 is used for separating inorganic substances such as soup spoons, chopsticks, plastic bags, rags and porcelain from the kitchen waste. And the waste residue discharge screw conveyor 2 filters percolate in the inorganic substance while conveying the inorganic substance.

As shown in fig. 2-5, the vibrating screen 1 includes a closed casing 1.1, and odor emission can be reduced by using the closed casing 1.1. The upper end of the closed shell 1.1 is provided with a feed inlet 1.2, and the feed inlet 1.2 is connected with a discharge port of the primary solid-liquid separation equipment, so that feeding is facilitated. The solid kitchen waste after the first solid-liquid separation enters the vibrating screen 1 through the feeding hole 1.2 and falls onto the first screen mesh 1.7. The first screen mesh 1.7 is box-shaped and has an opening at the upper end. Both ends are solid portion about the first screen cloth 1.7 bottom plate, and the through-hole is covered with in first screen cloth 1.7 bottom plate middle part. The bottom ends of the left and right solid parts are connected with a plurality of groups of compression springs 1.6, and the other ends of the compression springs 1.6 are connected with a beam 1.5 welded in the closed shell 1.1. The bottom end of the left solid part and the right solid part is positioned on one side of the compression spring 1.6, the vibration motor 1.8 is installed through the connecting plate, and the vibration motor 1.8 can drive the first screen mesh 1.7 to move up and down after being started, so that the screening is realized.

In addition, a notch 1.9 is formed in the left side of the group of compression springs 1.6 at the right end, the lower portion of the notch 1.9 is opposite to a second discharge port 1.4 of the closed shell 1.1, and the other end of the second discharge port 1.4 is connected with a waste residue discharge screw conveyor 2.

And the closed shell 1.1 is located and opens first discharge gate 1.3 below the left end, and first discharge gate 1.3 is arranged in the organic matter of tiny granule among the kitchen garbage to fall down, and first discharge gate 1.3 is connected with the breaker, is convenient for follow-up continuation breakage.

The waste residue discharging screw conveyor 2 comprises a screw conveyor main body 2.1 (adopting a shaftless screw blade), and the screw conveyor main body 2.1 is in accordance with the general structure of the existing screw conveyor. The improvement is that the tail part of the screw conveyer main body 2.1 is provided with an opening, the opening position is provided with a percolate collecting hopper 2.2, and the percolate collecting hopper 2.2 and the screw conveyer main body 2.1 are separated by a second screen 2.3. After most inorganic matter entered into screw conveyer main part 2.1, the motor drove helical blade and rotates, then upwards carries the inorganic matter, and at the in-process of carrying, filtration liquid then enters into filtration liquid downwards and collects in the filtration liquid collection fill 2.2, and the later stage is discharged from filtration liquid outlet 2.6.

The vibrating screen 1 is arranged obliquely downwards, the waste residue discharging spiral conveyor 2 is arranged obliquely upwards, and the inclination angle of the vibrating screen and the waste residue discharging spiral conveyor is determined according to the actual situation. The vibrating screen 1 inclines downwards, so that inorganic matters can fall from the notch 1.9 quickly under the action of vibration and dead weight. And the waste residue discharge screw conveyor 2 is obliquely and upwards arranged, so that the percolate can quickly flow downwards into the percolate collecting hopper 2.2 from a gap between the shaftless screw blade and the shell of the screw conveyor main body 2.1.

Preferably, an overflow channel 2.4 is arranged above the position between the tail end of the screw conveyor body 2.1 and the percolate collecting hopper 2.2, and a screen mesh hand-held basket 2.5 with an open upper end is arranged in the corresponding percolate collecting hopper 2.2. Vegetable leaves which cannot be crushed by the shaftless screw are piled up on the end of the shaftless screw, pressed upwards along the second screen 2.3, passed through the overflow channel 2.4 and collected in the screen basket 2.5. And opening the end cover at the later stage, and taking out the screen mesh hand basket 2.5 to clean the residual leaves in the screen mesh.

The working principle and the process are as follows: the solid kitchen waste after the first solid-liquid separation is fed into the feeding hole 1.2 and then falls onto the first screen mesh 1.7. In the process of vibrating the solid kitchen waste on the first screen mesh 1.7, most of organic kitchen waste falls down through the holes on the first screen mesh 1.7 and then falls into the crusher through the first discharge hole 1.3, and is crushed by the crusher. And the percolate and massive inorganic matters continue to move rightwards, fall down after moving to the notch 1.9, and enter the waste residue discharging screw conveyor 2 after passing through the second discharging port 1.4. Inorganic matters are conveyed upwards by the waste residue discharging screw conveyor 2 and finally fall down from a slag outlet at the upper end to enter the garbage can 3. The percolate is filtered by the second screen 2.3 and then enters the percolate collecting hopper 2.2, and is discharged into the storage pool through the percolate outlet 2.6 so as to be convenient for subsequent oil-water separation, and then swill oil is obtained.
