Description

Background Art

[0002] Kitchen waste is one of the main sources of domestic waste. In response to the increasing amount of kitchen waste, either a larger garbage collection and treatment device is set up to store it and treat it regularly; or on-site crushing, extrusion and dehydration are used to reduce the volume and quality of kitchen waste, thereby reducing the cost of transportation and the overall space occupied by kitchen waste storage. At the same time, the solid and liquid are separated and pre-treated, which makes it convenient to separate the oil and water and simplifies the terminal treatment process and procedures for kitchen waste.

[0003] There are two main types of small-scale, on-site food waste reduction and dry-wet separation equipment:

[0004] One is driven by a motor and includes a spiral auger, an auger barrel and other main structures. The auger barrel is usually equipped with a filter. According to the different material compositions of the food waste, the auger can also be made into a variable diameter from small to large to ensure the squeezing effect. The food waste is squeezed through the gap between the auger and the inner wall of the auger barrel, the liquid in the food waste is separated and drained, and the solid is discharged from the discharge port at the end, so as to achieve the effect of dry and wet separation;

[0005] The other is to add a set of crushing pre-treatment mechanism for food waste on the basis of the above-mentioned first structure and function, and the crushing methods include pressing, shearing, impact, grinding, etc., that is, the whole equipment is driven by one (chain or gear transmission) or two motors. Two sets of different mechanical structures are used in combination to achieve the reduction of food waste and dry-wet separation;

[0006] Although the above two types of equipment have been promoted and used to a certain extent, they have the following shortcomings and defects in actual application:

[0007] The first type of equipment can separate the solid and liquid of food waste by squeezing the spiral auger, but it cannot reduce the volume of food waste. If the food waste is large in size, it cannot be fully squeezed and pressed, and the spiral will be stuck. At the same time, if it processes flexible materials with strong fiber, it is easy to entangle the shaft and cause the spiral auger to be blocked.

[0008] The second type of equipment, although it has the crushing pre-treatment function and can avoid some of the defects of the first type of equipment, can reduce the volume and mass of food waste to a certain extent, and squeeze it more fully to achieve solid-liquid separation, but because of the addition of a crushing pre-treatment mechanism, and the crushing pre-treatment mechanism needs to be equipped with one to two motors for driving, or increase the transmission medium (chain or gear), and configure a separate electrical control system, the overall equipment occupies a large space, the overall energy consumption of the equipment increases, the overall production cost of the equipment increases, and the subsequent operation and maintenance costs increase.

[0114] The conveying section spiral blade 39 is used to convey and propel the food waste toward the discharging direction.

[0115] The shearing section spiral blade 40 cooperates with the fixed blade assembly 29 to shear and crush the food waste.

[0116] The reducing sleeve 41 reduces the cross-sectional space for the kitchen waste to pass through between the reducing sleeve 41 and the spiral shell assembly 17, so as to extrude the kitchen waste after it is conveyed, sheared and crushed, thereby achieving the effect of solid-liquid separation.

[0117] The extrusion section spiral blade 42 is used to push the food waste toward the discharge port assembly 21 while squeezing the food waste for solid-liquid separation.

[0118] The driven end short shaft 43 is used to fix the screw assembly 11 .

[0119] The driven end bearing 44 is used for positioning and limiting the position of the screw assembly 11 when it rotates.

[0120] refer to Figures 1 to 8 , the working process of the kitchen waste treatment equipment is as follows:

[0121] The kitchen waste is poured into the feeding trough 5, passes through the feed port 15 through the feed pipe 6, and reaches the position of the conveying section spiral blade 39 inside the cavity of the spiral shell assembly 17. At this time, the kitchen waste can be preliminarily separated into solid matter and oily and water waste liquid. The oily and water waste liquid is drained from the conveying section filter 16 and flows into the feed trough 30 for collection and then discharged through the residual liquid discharge port 31.

[0122] The driving device 2 drives the spiral assembly 11 to rotate, and pushes the preliminarily separated solid food waste materials along the spiral blade's rotation direction to the position of the shearing section spiral blade 40. There is a disconnection gap between the conveying section spiral blade 39 of the spiral assembly 11 and the shearing section spiral blade 40. Two fixed knife assemblies 29 are radially and symmetrically arranged at the disconnection gap position. The fixed knife assemblies do not rotate with the spiral blades and are bolted to the spiral shell assembly 17. The solid materials are pushed by the conveying section spiral blade 39, and when passing through the disconnection gap position, they are rotated and sheared by the two fixed knife assemblies 29, the conveying section spiral blade 39, and the shearing section spiral blade 40, so that the solid materials are sheared and crushed.

[0123] The crushed solid matter is driven by the shear section spiral blades 40 and is pushed forward axially toward the extrusion section spiral blades 42. When passing through the reducing sleeve 41, the cross-sectional area through which the crushed solid matter can pass gradually decreases. The volume of the crushed solid matter is squeezed by external force. In the process of being pushed toward the discharge port assembly 21 through the extrusion section spiral blades 42, the oily and water waste liquid contained in the solid matter is squeezed out, drained through the extrusion filter assembly 19, and flowed into the discharge trough 30 for collection, and then discharged through the residual liquid discharge port 31.

[0124] The crushed solid matter eventually reaches the position of the discharge port component 21 and contacts the pressing plate 23. As the subsequent kitchen waste is continuously pushed by the spiral component 11, the crushed solid matter will continue to gather and increase at the position of the discharge port component 21, and be squeezed against each other by the pressing plate 23. In this process, the crushed solid matter will produce oily and water waste liquid for a second time due to mutual squeezing, and will be drained into the discharge trough 30 through the squeezing filter component 19 to complete collection and discharge again.

[0125] When the crushed kitchen waste material accumulates at the position of the pressing plate 23 and reaches a certain amount, the thrust of the crushed kitchen waste material on the pressing plate 23 is greater than the reaction force of the spring 26, and the spring 26 is compressed, resulting in a gap between the contact edge of the pressing plate 23 and the discharge port assembly 21 to guide the crushed kitchen waste material out. At this time, a part of the crushed kitchen waste material is guided out of the gap and falls into the on-site collection tank or trash can. When the crushed kitchen waste material on the pressing plate 23 is reduced to a certain amount, the spring 26 is reset, and there is no gap between the contact edge of the pressing plate 23 and the discharge port assembly 21.

[0126] Repeating the above process can achieve the shearing and crushing reduction of kitchen waste and the extrusion of dry and wet separation, forming a separate collection and discharge process for kitchen waste solid matter and oily and water waste liquid. This can achieve a dual reduction in the volume and quality of kitchen waste, reduce the cost of removal and transportation, and reduce the overall footprint of the system.

[0127] During the working process, in order to better achieve the working effect of the kitchen waste reduction and dry-wet separation device:

[0128] The fixed blade assembly 29 is an independent modular component, which is bolted to the spiral housing assembly 17 and can be removed separately for replacement or repair when damaged by destructive external force.

[0129] The conveying section filter 16 and the extrusion filter assembly 19 are independent components. The conveying section filter 16 is fixed to the spiral shell assembly 17 with bolts, and the extrusion filter assembly 19 is fixed to the spiral shell assembly 17 with a ferrule. When damaged by destructive external forces, they can be removed separately for replacement or repair, or opened for inspection during equipment maintenance.

[0130] The outer diameter of the sleeve assembly 22 has spiral blades in the same direction as the food waste treatment output direction, the purpose of which is to accelerate the removal of the crushed food waste solid matter at the discharge port assembly 21 and reduce the accumulation of the crushed food waste solid matter in the equipment.

[0131] The second spring pressure plate assembly 27 can use the spring compression bolt 25 to adjust the compression distance of the spring 26, that is, adjust the reaction force of the spring 26, and make reaction force compensation adjustment when the spring 26 is loose after long-term use.

[0132] In order to ensure that the food waste is fully sheared, crushed, squeezed, and the oil and water waste liquids are separated in the cavity of the spiral shell assembly 17, under the condition of the same spiral blade outer diameter, the conveying processing capacity (pitch) of the conveying section spiral blade 39 should be greater than that of the shearing section spiral blade 40 and greater than that of the extrusion section spiral blade 42.

[0133] In the above technical scheme, the solid-liquid separation and volume and mass reduction of kitchen waste are achieved through crushing, extruding and dehydrating the kitchen waste. The equipment only needs to be equipped with one driving device. At the same time, the crushing, extruding and dehydrating processes are independent integrated structures. One set of electrical control system can meet the working conditions. The overall size of the equipment is small, the energy consumption is low, the production cost is lower than that of products in the same field with crushing pretreatment functions, and the operation and maintenance procedures are simple.
