The manufacturing process of this interlayer tank body is complicated and the manufacturing cost is high. In addition, because of the need for vacuum negative pressure when drying materials, the sealing performance of the drying tank is very high, and the double-shaft agitator needs to use two sets of mechanical seals, not only the cost is very high, but also the installation is very troublesome. And when the food waste is poured into the feeding hopper, too much oil and water will flow into the drying tank through the sorting cylinder, thereby prolonging the drying time and increasing the drying burden.

At the same time, the water pump in the desalting and degreasing device is started, and water is sprayed on the feeding hopper wall through the flushing pipe to remove the feeding hopper in time. Oil and salt adhered to the wall, and The material in the hopper is processed for salt and fat reduction. The oil discharged from the material after being twisted and squeezed and sprayed is collected in the liquid receiving tank and discharged to the oil-water separation device through the drain pipe. When the food waste is squeezed, The PLC controller then instructs the forward and reverse motor to rotate forward, the separation motor forwards, the lower conveying motor forwards, the gate drive motor drives the gate to move, opens the discharge port, and the forward and reverse motor drives the shaftless spiral rotation to twist and squeeze The latter materials are pushed into the sorting cylinder through the discharge port. When entering the sorting cylinder, under the rotation of the separating shaft, the knives, forks, chopsticks and other slender materials are exported through the separating blades, and other paste-like materials and hard materials such as bones. Under the centrifugal action of the separating shaft and the separating blades, the hard substances collide with the filter screen immediately under the centrifugal action to be crushed. The crushed powder and paste enter the diversion cavity through the filter screen and pass through the guide vane of the right hand. The flow and the left-handed baffle block cooperate with each other, and then the material is quickly pushed into the inlet of the drying tank through the discharge port under the rotation of the conveying shaft through the connecting guide plate, the PLC controller opens the electric ball valve, and the material enters the drying tank Then close the electric ball valve. During the drying process, the PLC controller instructs the electric heating element of the drying tank to heat up, and at the same time, inject the heat transfer medium, pump the heat transfer medium through the heat source, and enter with the liquid inlet pipe and the connecting pipe In the heat conduction disc, the heat conduction medium passes through the labyrinth-like inner flow gap, outer flow gap, inner flow gap, and outer flow gap repeated filling and bypassing on one side of the blocking plate, and finally flows into the liquid outlet on the other side of the blocking plate Into the stirring shaft, and then flow to the heat source part through the stirring shaft and the return channel on the periphery of the support frame in the stirring shaft, and the return channel between the return jacket and the liquid inlet pipe, and repeat the cycle to make the stirring shaft and the heat conduction circle The plate is filled with heat transfer medium to make the temperature uniform. During the drying process, the liquid inlet pipe is connected to the heat source, and the PLC controller controls the circulation pump and the stirring reducer in the heat source. The stirring reducer drives the driven sprocket to rotate and follow The sprocket drives the return water jacket, the mixing shaft and the heat conduction disc to rotate. During the rotation, the left and right spiral blades on the heat conduction disc fully turn the material and direct the material to the heat conduction disc of the material plate Position conveying, because there are 4 heat conduction discs on the left and right ends of the stirring shaft. The oblique copy board inclined to the outer circumference of the thermally conductive disc, through the oblique copy board, the material adhering on the left and right ends of the shell is hung down and transported to the middle of the shell, preventing the material from adhering to the shell during the drying process On the end faces of the two ends, there are two straight copy boards and two oblique copy boards staggered and evenly distributed on the other heat conduction discs. The same direct copy board and the same oblique copy board are located at both ends of the same heat conduction disc diameter, so that the material can be dried. When turning and pushing at the same time, and through the forward and reverse rotation of the drive motor, the drying speed of the material is accelerated; in the process of turning and conveying the left and right spiral blades driven by the heat conduction disc, it is located on the side wall of the shell in the gap of the heat conduction disc The broken blades are arranged at intervals to break the agglomerates in the material, so that the material is dried more evenly; the steam generated during the drying process is discharged through the air outlet, when the material is dried, open the discharge on the bottom side of the drying tank The material is conveyed by the left and right spiral blades to the heat conduction disc with the deflector, and the drying material is quickly pushed to the discharge port through the deflector; when the temperature in the drying tank rises to 80 degrees Celsius When the electric heating is stopped, the PLC controller starts the vacuum pump to start vacuuming the drying tank. When the vacuum in the drying tank reaches -0.06MPa, the compressor heating cable stops and the compressor starts to enter the drying stage. At the same time, the PLC The controller instructs the waste heat recovery devices 7 and 8 to work. The waste heat recovery devices 7 and 8 exchange heat with the steam generated during the drying process of the material in the vacuum drying device 5, and then condense the steam to form a liquid waste heat recovery device. The heat of the steam is recovered by the waste heat. The device recycles and produces hot water at 50-120°C, and a part of the hot water at 50-120°C is transferred to the interlayer in the drying tank and the disc dryer. The materials are uniformly heated, and another part of the hot water is delivered to the washing water tank 19. The 50-70°C hot water is used to wash the kitchen waste through the desalting and degreasing device 1; during the heating process, the hot water on the disc dryer The straight guide plate, the guide plate, the straight copy plate, the inclined copy plate, the left spiral blade, the right spiral blade fully stir the paste-like food waste to avoid the uneven heating of the food waste in the drying tank. Affect the drying quality. During the drying process, always keep the pressure in the drying tank at -0.081~-0.099MPa to make the drying The boiling point in the drying tank can be boiled at 50-65°C without heating to 100°C, which not only significantly accelerates the drying speed of the materials in the tank, shortens the drying time, but also significantly saves energy consumption; at the same time, through The waste heat recovery device reduces the temperature. After cooling, the condensate that becomes liquid with peculiar smell passes through the vacuum pump and discharges it into the vacuum pump circulating water tank. With the overflow of the vacuum pump circulating water tank, it flows to the oil-water separation device and finally discharged to In the sewage treatment system; when the water tank temperature sensor detects that the water temperature in the water tank is greater than or equal to 40°, the water tank replenishment solenoid valve will act, and the water tank will be supplemented with cold water and the temperature will be reduced to 33 degrees Celsius or less, and then water replenishment will be stopped; When the drying tank pressure sensor detects that the pressure in the drying tank is lower than -0.06MPa for 5 minutes, it triggers an abnormal vacuum pressure fault alarm, and the alarm signal can be displayed on the touch screen; or, on a PC or mobile phone.

When the temperature of the interlayer temperature sensor of the interlayer of the drying tank reaches the set 90-110°C, the PLC controller instructs the stirring reducer to stop, and the waste heat recovery device stops working. When the interlayer temperature sensor senses that the temperature drops to the set temperature, the PLC controls The device is to instruct the alarm to sound and prompt the material to be discharged.

When the oil-water separation device in this creation is working, the PLC controller is powered on. When the liquid level in the case reaches the lowest level of the low liquid level sensor, the PLC controller instructs the cold plate evaporator to go down for oil extraction, cooling and heating The system simultaneously cools the condensing plate and heats the degreasing condenser and water-cooled condenser. When the sewage temperature sensor in the chassis senses that the sewage temperature reaches the specified temperature, at the same time, the cold plate temperature sensor on the condensate plate senses the cold plate When the evaporator reaches the specified temperature, the specified temperature is higher than the freezing point of water and lower than the freezing point of oil. The PLC controller instructs the cold plate reducer to drive the condensing plate down to lift the oil. When the low level sensor senses that the condensate plate goes down to the specified When the liquid level, the low liquid level sensor is turned on, and the PLC controller instructs the cold plate reducer to drive the condensing plate to continue down for a certain distance And keep it until the cold plate temperature sensor on the condensing plate gives a temperature signal to achieve the effect of oil lifting, the PLC controller controls the cold plate reducer to drive the condensing plate to travel, when the upper limit position sensor of the oil scraper gives a signal of reaching the oil scraping position , The condensing plate reaches the oil scraping position, the cold plate reducer stops, and the PLC controller controls the oil scraping reducer to drive the oil scraping screw to drive the oil scraper to scrape the bottom surface of the condensing plate along the chassis. When the oil scraper reaches At the left end of the chassis, the left position sensor of the oil scraper is turned on and gives a signal, and the PLC controller instructs the oil scraper reducer to drive the oil scraping screw to stop. At this time, the oil push butt plate is connected to the oil removal connecting plate in the oil removal tank, and the PLC controls The oil removal mechanism is commanded by the device to move the oil removal plate along the inner wall of the oil removal tank from back to front. The oil removal plate drives the oil push butt plate to move through the oil removal connection plate, and the oil push plate drives the oil push plate to slide along the side wall of the moving oil storage tank. , The oil in the mobile oil storage tank is pushed into the oil removal tank. Since the temperature in the mobile oil storage tank is higher than the freezing point of the grease, after the grease enters the mobile oil storage tank, the grease in contact with the mobile oil storage tank becomes oil. Therefore, In the degreasing process, the oil will not stick to the oil storage tank and cannot be pushed out due to the solidified state of the grease, and the oil pushed into the degreasing tank will quickly turn into oil under the heating of the water-cooled condenser, and flow into the oil through the oil outlet. In the oil drum, when the oil removal plate runs to the front end of the oil removal tank, the position sensor in front of the oil removal plate gives a signal, and the PLC controller controls the oil removal reducer to drive the oil removal screw to stop. After the oil removal is completed, the PLC controller controls the oil removal The reducer drives the degreasing screw to reverse. When the degreasing plate runs to the rear end of the degreasing tank, the position sensor behind the degreasing plate gives a signal, and the PLC controller controls the degreasing reducer to drive the degreasing screw to stop and wait for the next degreasing Oil operation.

In the process of degreasing, the oil in the water passes through the slag screen and floats to the surface of the sewage, while the granular sludge and debris in the sewage are isolated under the slag screen by the slag screen. It is discharged by the sewage pump when lifting, which helps to ensure the cleanliness and high purity of the oil.

When the dirt at the bottom of the slag screen has accumulated to a certain extent, it is necessary to raise the granular dirt When there is mud or debris, the PLC controller instructs the sewage pump in the sewage lift backwashing device. When the sewage is lifted, the small through hole on the backwash pipe sprays high-pressure water to backwash the sludge at the bottom of the chassis to the sewage drain The tank is discharged by the sewage pump to the sewage receiving tank, and at the same time, it is sucked by the high pressure of the sewage pump to avoid the blockage of the slag screen. In the sewage discharge process, because the overflow pipe is provided with a one-way valve, it can prevent the sewage from flowing back into the cabinet through the overflow port when the sewage is lifted.
