专利号为201310440932.3,专利名称为餐厨废弃物预处理设备的发明专利,并已授权,该专利于通过在壳体上端设有投料斗和正反转电机,壳体内设有自动分选装置,生物杀菌祛臭祛味干燥装置,油水分离装置,电离除臭装置和汽体冷凝装置,所述投料斗经出料口与自动自动分拣装置的餐厨废弃物进料口相连通,自动自动分拣装置经餐厨废弃物出口与生物杀菌祛臭祛味干燥装置中的进料口相连通,自动自动分拣装置经出液口与油水分离装置相连通,生物杀菌祛臭祛味干燥装置经排气口与汽体冷凝装置相连通,气体冷凝装置与电离除臭装置相连通,达到了自动分拣、发酵处理速度快、发酵均匀、加热速度快、发酵时可自动充氧、气体除臭达标、环保无污染的作用。但还存在如下实质性不足:1、在发酵干燥时,由于采用减压干燥,干燥温度通常在140多度,不但产生大量的高温蒸汽还需要经电离除臭装置进行处理,干燥时间长、耗能高,由于冷凝效果差,导致蒸汽向外散发,而且,由于温度太高,会将餐厨废弃物中含有的有益菌、蛋白质等营养成分全部破坏,是餐厨废弃物中含有的蛋白质等营养成分会被部分破坏;2、当餐厨废弃物被倒入到投料斗内时,过多的油水会经分拣筒流入到干燥槽内,进而延长了干燥时间,增大了干燥负担;3、在餐厨废弃物通过投料斗进入分拣筒内分选时,由于分拣筒由进口端设有小直径过滤网,当细长的固状物进入分拣筒内时,不但很容易插入小直径过滤网内,导致分离轴的负载增大,分离效果不佳,而且分拣筒的小直径过滤网段出膏的含量高,导致排污管道被阻塞;4、当设备需要维护时,由于干燥槽、分拣筒都是整体,需要通过专用设备将轴和干燥槽,或者轴和分拣筒分离,拆装非常麻烦,费时费力。Patent No. 201310440932.3, the patent name is the invention patent of the kitchen waste pretreatment equipment, and has been authorized. The patent is provided with a hopper and a positive and negative motor at the upper end of the casing, and an automatic sorting device is arranged in the casing. a sterilization and deodorizing drying device, an oil-water separation device, an ionization deodorizing device and a vapor condensation device, wherein the feeding hopper is connected to the kitchen waste feeding port of the automatic automatic sorting device through the discharging port, and automatically and automatically The sorting device is connected to the feed port in the biological sterilization, odor and odor drying device through the kitchen waste export, and the automatic automatic sorting device is connected to the oil-water separation device through the liquid outlet, and the biological sterilization odor and odor drying device is The exhaust port is connected with the vapor condensation device, and the gas condensation device is connected with the ionization deodorization device, and the automatic sorting, the fermentation process is fast, the fermentation is uniform, the heating speed is fast, the oxygenation can be automatically performed during the fermentation, and the gas is deodorized. Standardized, environmentally friendly and non-polluting. However, there are still the following substantial disadvantages: 1. During fermentation drying, the drying temperature is usually more than 140 degrees due to drying under reduced pressure. Not only does it generate a large amount of high-temperature steam, but also needs to be treated by an ionization and deodorization device. The drying time is long and consumes. High energy, due to the poor condensation effect, the steam is emitted outwards, and because the temperature is too high, all the nutrients such as beneficial bacteria and protein contained in the kitchen waste are destroyed, which is the protein contained in the kitchen waste. The nutrients will be partially destroyed; 2. When the kitchen waste is poured into the hopper, too much oil will flow into the drying tank through the sorting cylinder, which will prolong the drying time and increase the drying burden; 3. When the kitchen waste is sorted into the sorting cylinder through the feeding hopper, since the sorting cylinder is provided with a small-diameter filter net from the inlet end, it is not only easy when the elongated solid material enters the sorting cylinder. Insertion into the small-diameter filter net causes the load of the separation shaft to increase, the separation effect is not good, and the content of the small-diameter filter network segment of the sorting cylinder is high, which causes the sewage pipeline to be blocked; 4. When the equipment needs In order to maintain, since the drying tank and the sorting cylinder are all integral, it is necessary to separate the shaft and the drying tank, or the shaft and the sorting cylinder by special equipment, which is troublesome and time consuming.
另外,现有的油水分离装置的分离方式大致可分为重力式分离、离心式分离、电分离、吸附分离、气浮分离等,这些油水分离方式均存在各自的实质性缺陷,油水分离时间长、提油效率低、出油纯度低,如重力式分离方式采用沉降池形式,会导致液体流动存在死区,部分液体得不到流动置换,水中有机质会逐渐腐败变臭;气浮分离方式会产生大量臭气;离心式分离方式设备动力部件维护困难,目前只应用于实验室的分析设备等。In addition, the separation methods of the existing oil-water separation devices can be roughly divided into gravity separation, centrifugal separation, electric separation, adsorption separation, air separation, etc. These oil-water separation methods have their own substantial defects, and the oil-water separation time is long. Low oil extraction efficiency and low oil extraction purity. For example, the gravity separation method adopts the form of sedimentation tank, which will lead to the dead zone of liquid flow, some liquids will not be replaced by flow, and the organic matter in water will gradually become corrupt and odor; the air flotation separation method will A large amount of odor is generated; the centrifugal separation method power unit is difficult to maintain, and is currently only used in laboratory analysis equipment.
另外,上述分离方法分离出的油水由于分离不彻底,导致油品差,储存及再利用困难。In addition, the oil and water separated by the above separation method are incompletely separated, resulting in poor oil quality, and difficulty in storage and reuse.

本发明解决其技术问题所采用的技术方案是:The technical solution adopted by the present invention to solve the technical problem thereof is:
一种餐厨废弃物处理方法,其特征在于在对物料进行自动处理时,PLC控制器指令料斗电动阀开启,打开密封盖,同时,启动闸板驱动电机动作,带动闸板封住出料口,然后停止,并同时启动正反转电机反转,使无轴螺旋对落入投料斗内的餐厨废弃物进行破碎拧挤,同时,启动降盐降脂装置中的水泵,通过冲洗管对投料斗壁进行喷水,及时除去投料斗壁粘附的油盐,并对进入投料斗内的物料进行降盐降脂处理,物料经拧挤和喷淋后排出的油液通过收液槽收集后通过排液管排到油水分离装置中,当餐厨废弃物被拧挤后,PLC控制器再指令正反转电机正转,分离电机正转、下输送电机正转,闸板驱动电机带动闸板上移,打开出料口,正反转电机带动无轴螺旋旋转将拧挤后的物料经出料口推入分拣筒中,当进入分拣筒时,在分离轴的旋转作用下,刀、叉、筷子等细长物质通过分离叶片导出,其它膏状物料和骨头等硬物质在分离轴和分离叶片的离心作用下,硬物质瞬间在离心作用下与过滤网发生碰撞而粉碎,粉碎后的粉末和膏状物经过滤网进入导流腔内,通过右旋导叶的导流和左旋挡板的配合阻挡,再通过连接导料板在输送轴的旋转作用下将物料通过下料口快速向干燥槽的进料口中推进,PLC控制器打开电动球阀,物料进入到干燥槽内,然后关闭电动球阀,PLC控制器指令搅拌电机动作,带动干燥槽内的搅拌轴对物料进行搅拌干燥,在干燥过程中,先通过PLC控制器指令干燥槽夹层的电加热元件电加热,当干燥槽内的温度上升到80摄氏度时,即停止电加热,PLC控制器启动真空泵,开始对干燥槽内抽真空,当干燥槽内的真空度达到-0.06MPa时,压缩机伴热带停止,压缩机启动进入干燥阶段,同时,PLC控制器指令余热热回收装置5工作,余热回收装置5对干燥装置4中的物料干燥过程中产生的蒸汽进行热交换后,将蒸汽冷凝形成液体余热回收装置蒸汽的热量被余热热回收装置再回收产生50-120℃的热水,其中50-120℃的热水传递至干燥槽内的夹层和搅拌轴的中空结构中,通过干燥槽内和搅拌轴和搅拌叶片对干燥槽内的物料进行再加热,另一部分至将热能传递到冲洗水箱32中,50-70℃的热水通过除盐除脂装置1对餐厨废弃物进行冲洗;在加热过程中,搅拌轴上的螺旋叶片对膏状的餐厨废弃物进行充分搅拌,避免干燥槽内的餐厨废弃物搅拌不均匀而影响干燥质量,干燥过程中始终保持干燥槽体内压力在-0.081~-0.099MPa,使干 燥槽内的沸点在50-65℃时即可沸腾,无需加热到100℃,不但显著加快了槽体内的物料的干燥速度,缩短了干燥时间,而且还显著节省了能量的消耗;A kitchen waste disposal method is characterized in that, when the material is automatically processed, the PLC controller instructs the hopper electric valve to open, opens the sealing cover, and simultaneously activates the ram drive motor to drive the ram to seal the discharge opening. And then stop, and at the same time start the reverse rotation of the positive and negative motor, so that the shaftless screw crushes and squeezes the kitchen waste falling into the feeding hopper, and at the same time, starts the water pump in the salt reduction and fat reduction device, through the flushing tube pair The hopper wall is sprayed with water to remove the oil salt adhered to the hopper wall in time, and the material entering the hopper is subjected to salt reduction and lipid reduction treatment. The oil discharged after the material is squeezed and sprayed is collected through the liquid collection tank. After being discharged into the oil-water separation device through the drain pipe, when the kitchen waste is screwed, the PLC controller instructs the positive and negative motor to rotate forward, the split motor rotates forward and the lower feed motor forwards, and the gate drive motor drives The gate is moved to open the discharge port, and the positive and negative motor drives the shaftless spiral rotation to push the screwed material into the sorting cylinder through the discharge port. When entering the sorting cylinder, under the rotation of the separation shaft, Knife, fork, chopsticks The elongate material is led out through the separation blade, and other hard materials such as paste material and bone are centrifuged under the separation axis and the separation blade, and the hard substance is instantaneously collided with the filter mesh under the action of centrifugation to pulverize, and the pulverized powder and paste are pulverized. The material enters the guiding cavity through the filter net, and is blocked by the diversion of the right-handed guide vane and the cooperation of the left-handed baffle, and then the material is quickly passed to the drying tank through the feeding port by the rotation of the conveying shaft through the connecting guide plate. The feeding port advances, the PLC controller opens the electric ball valve, the material enters the drying tank, and then the electric ball valve is closed. The PLC controller instructs the stirring motor to move, and drives the stirring shaft in the drying tank to stir and dry the material during the drying process. First, the electric heating element of the drying tank interlayer is electrically heated by the PLC controller. When the temperature in the drying tank rises to 80 degrees Celsius, the electric heating is stopped, and the PLC controller starts the vacuum pump to start vacuuming the drying tank when drying. When the vacuum in the tank reaches -0.06MPa, the compressor heating cable stops, the compressor starts to enter the drying stage, and at the same time, the PLC controller commands the rest. The heat recovery device 5 works, and the waste heat recovery device 5 heat-exchanges the steam generated during the drying process of the material in the drying device 4, and then condenses the steam to form a heat of the liquid waste heat recovery device. The heat of the steam is recovered by the waste heat recovery device to generate 50-120 Hot water of °C, wherein 50-120 °C hot water is transferred to the hollow structure of the interlayer and the stirring shaft in the drying tank, and the material in the drying tank is reheated through the drying tank and the stirring shaft and the stirring blade, and the other part To transfer the heat energy to the flushing water tank 32, the hot water of 50-70 ° C is washed by the desalting and degreasing device 1; during the heating process, the spiral blade on the stirring shaft is discarded by the paste-shaped kitchen The material is thoroughly stirred to avoid uneven mixing of the kitchen waste in the drying tank, which affects the drying quality. The pressure in the drying tank is maintained at -0.081 to -0.099 MPa during the drying process, so that the boiling point in the drying tank is 50-65 °C. It can be boiled without heating to 100 ° C, which not only accelerates the drying speed of the material in the tank, shortens the drying time, but also saves energy consumption.

其方法步骤如下:The method steps are as follows:
1)、制作冷凝板;1), making a condensation plate;
2)、对冷凝板进行降温冷凝,使得冷凝板的温度高于水的凝固点而等于或低于油的凝固点;2) cooling and condensing the condensing plate so that the temperature of the condensing plate is higher than the freezing point of the water and equal to or lower than the freezing point of the oil;

The inner wall of the degreasing tank moves from the rear to the front, and the degreasing plate drives the pushing oil butt plate to move through the degreasing connecting plate. The pushing oil butting plate drives the pushing plate to slide along the side wall of the moving oil storage tank, and pushes the oil in the moving oil storage tank to the degreasing trough. In the process of removing the oil, the oil in the moving oil storage tank is higher than the freezing point of the oil. The solidified state adheres to the oil storage tank and cannot be pushed out, and the oil pushed into the oil removal tank is rapidly converted into oil under the heating of the water-cooled condenser, and flows into the oil receiving barrel through the oil outlet hole.

在除油过程中,水中的油从隔渣网筛通过而上浮至污水表面,而污水中的颗粒状污泥、杂渣等通过隔渣网筛隔离在隔渣网筛下面,待污水提升时由污水泵排走,有利于保证油品的清洁度和高纯度。During the degreasing process, the oil in the water passes through the screen of the slag mesh and floats up to the surface of the sewage, while the granular sludge and the slag in the sewage are separated by the slag mesh screen under the slag mesh screen. Discharged by the sewage pump helps to ensure the cleanliness and high purity of the oil.
当隔渣网筛底部的污物积累到一定程度,需要提升颗粒状污泥或杂渣时,PLC控制器指令污水提升反冲洗装置中的污水泵,污水提升时反冲洗管上的小通孔喷出高压水将机箱底部污泥杂渣等反冲洗至污水排水箱并由污水泵排出至污物接收池中,同时通过污水泵的高压抽吸,避免了隔渣网筛的阻塞。在排污过程中,由于溢流管上设有单向阀,能够防止污水提升时污水通过溢流口回流至机箱内。When the dirt at the bottom of the slag mesh has accumulated to a certain extent, it is necessary to raise the granular sludge or the slag, the PLC controller commands the sewage pump in the sewage lifting backwashing device, and the small through hole on the backwashing pipe when the sewage is lifted The high-pressure water is sprayed to backwash the sludge residue at the bottom of the chassis to the sewage drain tank and discharged into the sewage receiving pool by the sewage pump. At the same time, the high-pressure suction of the sewage pump avoids the blockage of the slag mesh screen. In the sewage discharge process, since the check valve is provided with a one-way valve, it is possible to prevent the sewage from flowing back into the casing through the overflow port when the sewage is lifted.
