In addition, the storage box 310 may be further provided with a pressure sensor as needed, and the pressure sensor may automatically measure the weight of the dry garbage in the storage box 310, so as to automatically calculate the recycling value or notify the user of the emptying of the storage box 310.
The controller in the drying and collecting unit 300 is connected with the biological bacteria adder, the stirring assembly and the heating assembly in a control and coordination manner, and is used for controlling and coordinating the biological bacteria adder, the stirring assembly and the heating assembly to rapidly dry and complete the mixing of the biological bacteria and efficiently purify the storage box 310.
The controller can be formed in various forms such as a corresponding control chip, a PLC and the like, and the control mode can be a wired mode, a wireless mode, a local operation or a remote operation.
In addition, when the wet garbage treatment device with the structure is applied, the containing box 310 can be connected with hot air generated in family life and used for drying the particulate garbage in the containing box 310, so that the heat energy can be recovered, the heat utilization rate is greatly increased, the waste is avoided, the resources are saved, and the use cost is reduced.
Referring to fig. 4, a specific application example of the wet waste management device solution given in this example is shown.
As can be seen from the figure, in the present embodiment, the above-mentioned pulverizing and granulating unit 200 and the dry aggregate unit 300 are directly placed in a box 500, rollers are disposed at the bottom of the box 500, a feed inlet 510 is disposed at the top of the box 500, the feed inlet 510 is directly inserted into the kitchen table 600, and an induction cover 610 is disposed on the feed inlet 510, so that the garbage on the kitchen table 600 can directly fall into the pulverizing and granulating unit 200 to be pulverized and extrude the pulverized wet garbage, thereby separating the moisture in the wet garbage, discharging or recycling the separated reclaimed water, dehydrating and extruding the garbage into granular garbage, discharging the granular garbage into the dry aggregate unit 300, drying, purifying, putting in bio-digestive bacteria to cultivate, and converting the garbage into high-grade bio-bacterial fertilizer.
In addition, a water purifier 520 is further provided in the case 500, water separated from the pulverizing and granulating unit 200 may flow down to the water purifier 520 for purification, and a drain outlet 521 is provided in the water purifier 520 to facilitate direct use of the purified water.
Furthermore, a controller 700 may be disposed in the box 500, and the controller 700 may control the operations of the pulverizing and granulating unit 200 and the drying and collecting unit 300, respectively, for convenience of operation.
Thus, when the box 500 is needed to be used, the box 500 can be moved to the corresponding kitchen table 600, and the feed port 510 is inserted into the kitchen table 600, and when the box is not needed to be used, the box 500 only needs to be directly moved away from the kitchen table 600, which is very convenient.
Meanwhile, the separate use of the dry aggregate unit 300 may also achieve a processing function.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
