Further, in order to enable the heat of the heating film 41 to be uniformly and rapidly transmitted to the barrel body 1, as shown in fig. 6, the heating film 41 is fixed on the surface of the barrel body 1 through a heat conduction layer, for example, the heat conduction silica gel 42 is fixed, and on the one hand, the heat conduction silica gel 42 can provide viscosity for the attachment of the heating film 41, so that the attachment of the heating film 41 is facilitated, and meanwhile, the heat conduction is good, so that the heat of the heating film 41 can be rapidly and uniformly transmitted to the barrel body 1. Of course, in other embodiments, the heat conductive silicone 42 may be replaced by heat conductive silicone grease.
In addition, in the drying process, the temperature of the materials in the barrel is already at a relatively high temperature, the temperature of the newly-entered materials is low, and the temperature difference between the newly-entered materials and the high temperature affects the evaporation and fermentation processes of the materials in the barrel, therefore, if a whole heating film is adopted to coat the circumferential wall of the whole barrel 1, the temperatures of different positions in the barrel are not adjustable, and in order to enable the newly-entered materials to reach similar temperatures when being mixed with the original materials in the barrel so as to reduce the influence of the temperature difference, the heating temperature of the area where the newly-entered materials are located can be higher than the temperatures of other areas, so that the cooled materials can be heated as soon as possible.

As shown in fig. 7 and 8, one side of the lower plate 912 is pivotally connected to a fixed connecting seat 95, the connecting seat 95 is fixed to the bracket 18, and a hole on the connecting seat 95 connected to the lower plate 912 is a longitudinal waist-shaped hole 951, a push-pull device 96 for driving the connecting seat 95 to rotate is disposed at the bottom of the lower plate 912, the push-pull device 96 may be an air cylinder, a hydraulic cylinder, or an electric push cylinder, and the like, one end of the push-pull device 96 is pivotally connected to a connecting seat 97 located at the bottom of the lower plate 912, and a hole on the connecting seat 97 connected to the push-pull device 96 is a longitudinal waist-shaped hole 971, and the other end of the push-pull device is pivotally. Under normal conditions, the push-pull device 96 applies upward jacking force to the lower plate 912 to enable the sealing ring 914 on the lower plate to be attached to the flange 94 on the polygonal cover body 93, so that the lower end opening of the polygonal cover body 93 is effectively blocked; when the bottom plate 91 needs to be opened, the push-pull device 96 applies a downward pulling force to the bottom plate 91, so that the bottom plate can rotate around a connecting shaft of the bottom plate and the connecting seat 95 to be opened, and blanking can be performed.
Of course, in other embodiments, the weighing device 10 may be an electronic scale, and the receiving chamber 9 may be a trough body placed on the electronic scale, but this structure is not easy to perform automatic discharging compared to a structure in which a weighing sensor is integrated on a bottom plate.
As shown in fig. 9, in order to reduce heating energy consumption, low-temperature drying may be achieved by evacuating the interior of the tub 1 to reduce a boiling point, and therefore, the evacuation device 5 may be further connected to the exhaust port 17 on the tub 1, and the evacuation device 5 may be any known device having an air evacuation function, preferably a vacuum pump, and in addition, during evacuation, the vacuum pump may discharge steam generated by evaporation in the tub 1 from the inside of the tub 1, and since the steam contains oil, as shown in fig. 10, the exhaust port of the evacuation device 5 is connected to the oil-water separator 40 through a pipeline, so that separation of oil and water may be achieved for respective recycling. Of course, the exhaust port 17 may be directly connected to the oil-water separator 40 if a vacuum pump is not connected.
In addition, in order to ensure the vacuum degree in the barrel body 1, as shown in fig. 2, an electric valve 30 is arranged at each feed inlet 11, and the electric valve is adopted because when slurry is supplied on line, the opening force of a conventional electromagnetic valve is small due to the large viscosity of the slurry and the like, and the problem that the conventional electromagnetic valve is unsmooth to open or cannot be opened exists, so that the electric valve is adopted to ensure the smoothness and reliability of opening.

And, the conducting pressure of the first check valve 60 is greater than the negative pressure formed in the barrel body 1 when the vacuum pumping device works, so that the situation that the negative pressure in the barrel body 1 leads to the conduction of the first check valve to destroy the vacuum degree in the barrel body 1 can be effectively avoided.
Further, as shown in fig. 4, a second check valve 71 is disposed on the pipeline 7, which may be an overflow valve, a check valve, etc., and the second check valve 71 allows the fermentation broth outside the barrel body 1 to enter the barrel body 1, and the conduction pressure of the second check valve is greater than the negative pressure formed in the barrel body 1 when the vacuum pumping device works, so that the second check valve is prevented from being opened due to the negative pressure adsorption inside the barrel body 1, the vacuum degree of the barrel body 1 is damaged, and when the fermentation broth is not supplied, the sealing performance of the barrel body can be effectively ensured, and the vacuum degree is ensured.
When the electric heating device works, the electric valve, the motor, the cylinder, the weighing sensor, the temperature sensor, the vacuum height measuring equipment, the power supply of the heating device, the electric parts such as the pump and the like are all connected to the control device, for example, a PLC control system, and the PLC control system controls the operation of each part according to the logic program compiled in the PLC control system and the set operation parameters.
The method for drying the kitchen waste crushed material by using the quantitative discharging type fermentation equipment is specifically described as follows:
s1, providing the quantitative discharging type fermentation equipment of the embodiment;
s2, sealing the barrel body after the material is introduced into the barrel body;
s3, starting heating by the heating device;
and S4, the driving device starts to drive the spiral conveying shaft to drive the material to be stirred in the barrel body for a preset time.
S5, after the materials are fermented and/or dried in the barrel body, the materials are discharged from the discharge port 12 under the drive of the spiral conveying shaft, and then are convenient for quantitative bagging or packaging, the fermentation method further comprises the step S7, after the materials are discharged out of the barrel body, the materials are collected in the material receiving bin 9, the materials collected in the material receiving bin 9 exert pressure on the material connecting plate 911 to trigger a weighing sensor, the weighing sensor transmits data to a control device, when the weight reaches a target weight, the control device controls the spiral conveyor to stop extruding the materials out of the barrel body, meanwhile, the control device controls the push-pull device to be started to open the bottom plate 91, and at the moment, the materials in the material receiving bin 9 fall into a packaging bag or a barrel under the action of gravity to achieve quantitative packaging.
And in the step S2, the feed inlet of the quantitative discharging fermentation device may be connected through a screw conveyor or a pipeline with a pump, and during feeding, the screw conveyor or the pump is started, and the electric valve is opened to introduce the crushed kitchen waste into the barrel 1, thereby realizing on-line feeding and continuous processing. When the screw conveyer or the pump does not work, the first one-way valve keeps a closed state, so that the sealing state in the barrel body is kept.
In said step S3, the temperature of each temperature partition is between 35 ℃ and 60 ℃, preferably between 36 ℃ and 45 ℃; more preferably between 38 and 42 ℃, because the material can be boiled and evaporated in the above temperature range under the above vacuum condition, so as to be discharged out of the barrel body 1 along with the pumping of the vacuum device, and meanwhile, in this temperature range, the zymocyte can grow and react with the material more easily, so as to eliminate the peculiar smell in the material and increase the nutrient in the material.
Moreover, the temperature of the first heating subarea can be higher than that of the subsequent heating subarea, so that the temperature can be quickly raised to the temperature of the subsequent heating subarea, and the temperature of the newly introduced material is not lower than 35-60 ℃ before the newly introduced material contacts with the original material of the barrel body 1. Of course, it is also possible to bring the temperature to the above-mentioned temperature range by increasing the residence time of the material in the first heating zone.
In step S4, the driving device controls the retention time of the material in the barrel to be between 1 and 75 hours, preferably between 24 and 72 hours, and in the specific operation, the driving device drives the spiral conveying shaft to rotate forward for a certain distance and then turn over, so that the material can move forward and backward in the barrel, and thus the material can be moved forward and backward.
Further, in the drying process, the process of adding zymophyte into the material is also included, namely the step of S6 is also included, when or after the material enters the barrel body, a zymophyte supply pipeline is opened, zymophyte liquid is pumped into the spray head through equipment such as a pump, and zymophyte is sprayed on the material.
Further, in the drying process, the method also comprises the step S7, wherein the vacuumizing device is started to enable the interior of the barrel body to reach the target vacuum degree; in this step, the vacuum-pumping device may be kept in a vacuum-pumping state all the time, but, correspondingly, the energy consumption of the vacuum-pumping device is high, so that in a preferred implementation, the vacuum-pumping device may be operated intermittently, and specifically, the step S7 includes the following processes:
s71, the vacuum extractor (vacuum pump) is started to make the barrel reach the target vacuum degree and then stopped, preferably when the relative pressure reaches the vacuum degree between-98.5 KPa and-80 KPa, for example, the vacuum extractor is stopped.
And S72, when the vacuum degree in the barrel body is reduced to the lower limit value, the vacuumizing device starts to vacuumize again to the target vacuum degree and stops, and preferably, when the vacuum degree in the barrel body 1 is reduced to-20 Kpa (relative pressure), for example, the vacuumizing device starts.
S73, repeating the step S72.
Therefore, the energy consumption of the vacuum pumping device can be effectively reduced, and the vacuum degree in the barrel can be maintained at a relatively low boiling point temperature.
Meanwhile, in the step S7, the fluid discharged from the vacuum extractor is introduced into an oil-water separator for oil-water separation to obtain oil and wastewater, wherein the oil can be recycled; the waste water can be collected, treated and discharged.
Of course, the above sequence numbers of S1-S7 are not the only limitations on the operation process of the equipment, such as heating and vacuum-pumping at the same time during actual use; or feeding, heating, vacuumizing and conveying by the spiral conveying shaft can be carried out simultaneously; or spraying the zymogen liquid before the materials enter the barrel body 1; in another embodiment, the fermentation tubes may be sprayed to the material inside the barrel, the material is stirred by the reciprocating rotation of the screw conveying shaft, and then the barrel is heated by the heating film to reach the proper growth temperature of the fermentation tubes without vacuum pumping.
The invention has various embodiments, and all technical solutions formed by adopting equivalent transformation or equivalent transformation are within the protection scope of the invention.
