Description
Technical Field
The invention belongs to the technical field of machinery, and relates to a solid-liquid separation device.
Background
In daily life, a large amount of kitchen waste is generated due to the living needs of human activities, and the kitchen waste is often a mixture of solid, liquid, pasty food residues and the like. In general, kitchen wastes generated in households and restaurants are collected through a garbage can and then uniformly sent to a garbage collection station or a garbage disposal plant for centralized treatment. However, a certain time is needed in the garbage collection and transportation process, kitchen garbage is generally organic matter, and is easy to ferment, mold and stink, and the generated stink and sewage pollute the environment and destroy the sanitation of a kitchen. Therefore, it becomes extremely important to rapidly treat kitchen waste.
The Chinese patent literature data discloses and proposes a solid-liquid separation garbage disposer [ application number: CN201410284710.1; bulletin number: 104162534B ], comprising a workbench, a garbage crusher, a solid-liquid separation device and an electric cabinet. When the kitchen garbage crusher is used, kitchen garbage is put into the kitchen garbage crusher from the putting port of the garbage crusher, the kitchen garbage is crushed and ground by the garbage crusher, large garbage is ground into small garbage, then the garbage is dehydrated by the solid-liquid separation device, liquid is discharged from the water outlet, and solid is discharged from the discharge port. After the solid-liquid separation is carried out on the garbage, the total amount of the garbage can be reduced on one hand, and the pollution of the garbage to a kitchen can be reduced on the other hand.
The solid-liquid separation device of the garbage disposer comprises a filter cylinder and a spiral auger. The spiral auger is also called as a conveying rod and comprises a central rotating shaft and spiral blades, wherein a cutter is arranged at the upper end of the central rotating shaft, and the lower end of the central rotating shaft is connected with a motor. The cutter is L-shaped, the cutter is fixed on the radial direction of the central rotating shaft, and the cutter is provided with two cutters and takes the axle center as a symmetrical point. The screw blades are fixed on the outer surface of the central rotating shaft, and the screw pitches between adjacent screw blades gradually decrease from bottom to top, namely, the screw pitch at the lowest end is the largest, and the screw pitch at the uppermost end is the smallest. When the garbage conveying device works, the motor drives the spiral auger to rotate, and the spiral blades rotate to convey garbage from the lowest end to the uppermost end of the auger and then convey the garbage to the discharge port to be discharged after passing through the cutter. The pitches of the spiral blades gradually decrease from bottom to top, so that the volume of garbage among the spiral blades is continuously compressed, and a compacting and dewatering effect is generated. In the dehydration mode, the smaller the screw pitch at the upper end of the spiral blade is, the more solid garbage is extruded, the better the dehydration effect is, and the larger the rotation acting force required by the rotation center shaft is, so that the overload of a motor is easily caused, and the dehydration process cannot be smoothly carried out; however, if the pitch of the upper ends of the helical blades is enlarged, the load of the motor is reduced, mixed garbage cannot be compacted, as much water is discharged as possible, and the dewatering effect is also greatly reduced.
In order to improve the dehydration effect, the common technical means is to reduce the screw pitch at the upper end of the helical blade and provide a high-power motor, so that the garbage compaction improves the dehydration effect and the solid garbage is smoothly discharged, but the high-power motor is more expensive and has high energy consumption, which is not beneficial to market competition. Or the spiral blade is provided with a heating device, and the water is dehydrated by heating and evaporating the water, so that the equipment cost is increased, and the market competition is not facilitated.
