The automatic belt conveyor comprises a driving device 1, a main roller 2, a carrier roller 3, a conveying belt 4, a roller shaft 5, a first roller 6, a second roller 7, a groove 8, a frame body 9, a driving shaft 10 and a driven shaft 11.

Detailed Description

As shown in fig. 1 to 4, the household garbage squeezing mechanism comprises a driving device 1, a main roller 2, carrier rollers 3 and a conveying belt 4, wherein the conveying belt 4 is arranged between the main roller 2 and the carrier rollers 3, each

main roller

2 and 2 carrier rollers 3 are used in cooperation, the 2 carrier rollers 3 are respectively arranged on two sides of the main roller 2 used in cooperation with the carrier rollers, the driving device 1 is used for driving the main roller 2, and holes for draining liquid are formed in the conveying belt 4. The conveyer belt 4 is made of metal, and bearing capacity is guaranteed. Through the combined use of 1

home roll

2 and 2 bearing

rollers

3, 3 rollers constitute triangle-shaped, realize effective stable extrusion to domestic waste on the conveyer belt 4, the liquid that extrudes flows out through the hole on the conveyer belt 4. The gap on the conveying belt 4 can be a round hole or an elliptical hole, etc. The household garbage extruding mechanism is simple in structure, efficient in extruding and free of slipping in extruding.

The household garbage squeezing mechanism further comprises a driving shaft 10 and a driven shaft 11, the conveying belt 4 is a closed conveying belt 4, the driving shaft 10 and the driven shaft 11 are respectively arranged at two ends of the closed conveying belt 4, and the driving device 1 is used for driving the driving shaft 10. The domestic garbage extrusion mechanism further comprises a frame body 9, and the driving device 1, the main roller 2, the carrier roller 3, the conveying belt 4, the driving shaft 10 and the driven shaft 11 are respectively installed on the frame body 9.

The main roller 2 comprises a roller shaft 5, a first roller 6 and a second roller 7, the roller shaft 5 is arranged at two ends of the first roller 6 respectively, the second roller 7 is sleeved on the outer circumference of the first roller 6, the second roller 7 is made of rubber, and the roller shaft 5 drives the first roller 6 and the second roller 7 to rotate simultaneously under the driving of the driving device 1.

The rubber thickness of the second roller 7 is 40mm +/-5 mm. The optimization setting of 7 thickness of second roller to domestic waste's characteristics, realizes that domestic waste after the breakage-screening can both effectually pass through every squeeze roll, and this thickness of rubber material can provide sufficient deflection to the squeeze roll when the extrusion, guarantees that the solid particle thing that meets can both pass through the squeeze roll. When the rubber material thickness of second roller 7 was too thick, the elastic deformation volume increase of rubber material can weaken relatively to the extrusion ability of liquid, and when the rubber material thickness of second roller 7 was too thin, the elastic deformation volume of rubber material was too little, and the granule that the solid matter is slightly bigger can't pass through smoothly again, or is detained before the squeeze roll always, or passes through the squeeze roll by force, but can cause the damage to domestic waste conveyer belt 4.

Further, a groove 8 is formed in the circumferential surface of the second roller 7, and the groove 8 is used for allowing household garbage to pass through quickly during initial extrusion. The groove 8 is formed in the circumference of the second roller 7. Namely, the second roller 7 always keeps a uniform and large passing space with the garbage conveyor belt 4 when rotating. The inclined planes at the two ends of the groove 8 can also play a regular role in domestic garbage, namely the domestic garbage is gathered in the groove 8. According to the practical situation of domestic waste treatment, can set up the multiunit squeeze roll (a set of squeeze roll is 1

main roll

2 and 2 bearing roller 3's combination uses), realize multistage extrusion operation. During the multi-stage extrusion operation, the depth of the groove 8 on the second roller 7 can be gradually reduced, so that the extrusion efficiency can be better improved. A drain groove can be formed in the groove 8, so that extruded liquid can be conveniently and quickly separated from the second roller 7.

Further, a rubber layer is sleeved on the outer circumference of the carrier roller 3. The supporting roller 3 is mainly used for providing a supporting force for the main roller 2 and the conveying belt 4 and ensuring the extrusion effect of the extrusion mechanism.

Further, the thickness of the rubber layer is 20mm +/-5 mm. The thickness setting of 3 rubber layers of bearing roller has guaranteed to have certain elastic deformation volume on 3 surfaces of bearing roller, guarantees passing through smoothly of solid particle thing.

According to the main components of domestic waste, this application optimal design extrusion clearance, better satisfied domestic waste's extrusion needs. When the number of the main rollers 2 is more than 3, starting from the feeding end of the household garbage extruding mechanism, the gap between the first main roller 2 and the carrier roller 3 used in cooperation is 15mm +/-2 mm, the gap between the second main roller 2 and the carrier roller 3 used in cooperation is 5mm +/-2 mm, and the gap between the third main roller 2 and the carrier roller 3 used in cooperation is 3mm +/-2 mm, so that the liquid is extruded and removed step by step. When the main roll 2 has more than 2, the extrusion operation of extrusion mechanism is exactly for multistage extrusion, through the setting that the clearance reduces step by step between every level main roll 2 and the bearing roller 3 that the cooperation was used, can promote domestic waste's extrusion efficiency and extrusion effect, what figure 1 demonstrates is 4 level extrusion operations that the combination of 4 main rolls 2 formed, and the clearance is 0 between fourth main roll 2 and the bearing roller 3 that the cooperation was used. The main roll 2 and the supporting roller 3 that the cooperation was used clearance in addition the recess 8 on the pan feeding end main roll 2 circumference, both superposes, can provide bigger space for domestic waste. The closer to the discharging end, the smaller the gap between the main roller 2 and the carrier roller 3 matched with the main roller, the shallower the depth of the groove 8 on the circumference of the main roller 2, and the smaller the space for extruding the domestic garbage.

It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
