Description
Technical Field
The invention relates to preposed dewatering treatment of food residues and other organic matters in the fields of catering, fruit and vegetable, food processing and the like, in particular to an extrusion dewatering device.
Background
Various extrusion dewatering devices are available in the market, and the working principle of the devices is that materials to be processed are gradually pressed in a narrow cavity by using a reducing and distance changing mode of spiral extrusion, so that moisture in the materials is extruded and discharged and dried. The structure mainly comprises three parts: the screw extrusion device comprises a screw extrusion rod, a pressing cage and a discharge port pressurizing device, wherein the screw extrusion device is provided with a single shaft and a double shaft, the pressing cage is formed by welding a structure of steel bars into a cylinder, and the extrusion rod is processed into a whole by a machine tool. The machine is used for treating the livestock manure, the extrusion effect is also good, the dewatering can reach or exceed 50 percent, but the machine is large, three meters or even longer, and the occupied area exceeds one square meter; the similar small-sized squeezing and dewatering machine is also available in the market, no matter whether the machine is a large-sized machine or a small-sized machine, the effect of dewatering kitchen garbage is unsatisfactory, the dewatering effect is poor, the dewatering rate is 30-40%, the effect of effectively and comprehensively utilizing the garbage cannot be achieved by using the machine for dewatering the kitchen garbage at present, due to the fact that the pressing cage is integrated, if the pressing cage is blocked or clamped by other hard materials, time and labor are wasted when the whole pressing cage is detached, the whole pressing cage cannot be detached for 1-2 persons, and the time from half a day to half a day is short, so that the machine has many disadvantages when kitchen garbage in catering industry is converted into feed to be comprehensively utilized or is made into a small-sized machine for treating kitchen garbage at other sources.
The conversion of kitchen waste into feed ensures that the feed raw materials cannot contain spoiled substances. The pressing cage can not be quickly cleaned at any time and any place, kitchen residue in the pressing cage is removed, and the quality of the prepared kitchen waste into feed can not be guaranteed; in other small machines, the extraction cage cannot be conveniently disassembled, and once the machine is blocked or stuck, the maintenance cost of the machine is high, which causes great obstruction to the sale and use of the machine. In spite of the problem of disassembling the press cage of such machines, the reason why a large machine can dewater fecal garbage and even kitchen garbage by 50% or more but a small machine cannot be because the large machine is mainly long enough in extruded length and has enough dewatering distance compared with the small machine. For the processing of source, receive the restriction in space, the mainframe can not place and carry out the local processing to kitchen garbage at the source. After analysis and comparison of the existing extrusion configurations of large and small machines, it has been found that the design of their screw extrusion bars and cages has a number of disadvantages, including: 1. the spiral reducing and variable pitch of the extrusion rod are unreasonable, the extrusion dehydration of the garbage is realized mainly through reducing, and the reducing characteristics of the extrusion rod are that the front section has a large size and the rear section also has a large size, rather than gradually reducing step by step to realize step-by-step pressurization dehydration; 2. the design of the pressing cage is that the cylinder is welded into a whole by steel supports, and the integral cylinder is not beneficial to maintenance, including convenient removal of residues in the pressing cage to ensure the quality of raw feed materials; 3. the inner parts of the squeezing cages are not provided with teeth, the teeth are used for preventing the garbage from rotating along with the rotation of the screw rod in the rotating process of the screw rod, the front garbage stops or slows down moving due to the prevention of the teeth, the rear garbage rotates along with the screw rod, so that the front garbage and the rear garbage move oppositely to cause mutual extrusion and forward propulsion of the spiral sheets, the garbage is pressed all the way forward, the squeezing cages do not have the teeth, the garbage rotates along with the rotation of the screw rod, and as a result, a pressurizing device which can be manually adjusted is added at the position of the discharging port to ensure enough squeezing force of water at the position of the discharging port to ensure that water is removed, so the friction force between the squeezing rod and the squeezing cages becomes large, and the motor is required to drive the machine to normally operate and discharge the water, as a result, the motor of the small machine can reach three kilowatts, and the motor of the small machine can reach six kilowatts and seven kilowatts, which is not beneficial to controlling the size of the machine and controlling the cost and saving the energy consumption.
