Description

Technical Field

[0001] The utility model relates to a kitchen waste treatment device, in particular to a food waste biodegradation device. Background Art

[0002] In daily life, especially in industries such as food processing, food service, and canteen food supply, a large amount of kitchen waste is often generated. These kitchen wastes are relatively messy in variety and very difficult to handle. Especially because they contain extremely high moisture and organic matter, they are prone to decay and produce a foul smell.

[0003] Of course, some existing manufacturers have also designed some degradation devices for treating kitchen waste. However, most of these degradation devices simply pour biological strains directly into the kitchen waste for stirring, without separating the solid and liquid components in the kitchen waste. This results in the by-products outputted by them still being not easy to clean up. In addition, the existing kitchen waste degradation devices are not intelligent enough and cannot be fully automated. Moreover, most of the existing kitchen waste degradation devices also use the stirring method to mix the kitchen waste and biological strains. And the existing degradation devices often do not have safety devices. When personnel pour food, the stirring device below is still running normally, which easily leads to safety problems.

[0004] In view of the above defects, the applicant has designed a food waste biodegradation device. Content of the Utility Model

[0005] In order to solve the above technical problems, an embodiment of the utility model provides a food waste biodegradation device, including: a box body, a pressing and lifting machine, a strain lifting machine, a grinder, and a mixer;

[0006] The box body includes: a food waste treatment part, a strain treatment part, and a grinding and stirring part. A feeding hopper is arranged above the food waste treatment part. The pressing and lifting machine is arranged below the feeding hopper. A liquid leakage port is arranged at the bottom of the pressing and lifting machine, and a discharge port is arranged at the top. An oil-water separation device is arranged below the liquid leakage port.

[0007] A biological strain container is arranged inside the strain treatment part. The strain lifting machine is arranged inside the biological strain container. The strain lifting machine transports the strains to the mixer.

[0008] The grinder is arranged inside the grinding and stirring part. The input port of the grinder is connected to the discharge port of the pressing and lifting machine. The mixer is arranged below the output port of the grinder. A slag discharge port is arranged at the bottom of the mixer. Further, the mixer can mix and stir the kitchen waste and the biological strains and output through the slag discharge port.

[0009] Among them, the oil-water separation device is partitioned into an oil discharge chamber and a water discharge chamber by a partition plate. The bottoms of the oil discharge chamber and the water discharge chamber are interconnected. An oil discharge port is provided on the side wall of the oil discharge chamber, and the side wall of the water discharge chamber is connected to a drainage pipeline through a drainage port.

[0010] Among them, the pressing and lifting machine includes: the pressing and lifting motor, the screw rod, and the screw rod barrel. The pressing and lifting motor can drive the screw rod to rotate inside the screw rod barrel, and a plurality of leakage holes are provided at the bottom of the screw rod barrel.

[0015] Implementing the present utility model has the following beneficial effects:

[0016] ① Solid-liquid and oil-water separation. During the processing of this device, when the pressing and lifting machine is used to lift the food waste, the kitchen waste will be pressed. The liquid part flows into the oil-water separation device for oil-water separation, and the solid components are lifted to the grinder by the screw rod for subsequent processing, thereby realizing the classified output of oil, water, and solid components. Compared with the traditional direct output, it avoids the problem of easier odor emission due to solid-liquid mixing after output, and the classified output also makes it easier to collect and recycle oil, water, and solid components uniformly. ② It can be automatically processed and is safer. The PLC controller of this device can control the pressing and lifting motor and the mixing motor to work, thereby realizing automatic production. At the same time, the human body sensing module can sense the dumping induction area above the feeding hopper, and when a person stands in the dumping induction area to dump food residues, the pressing and lifting motor and the mixing motor below can temporarily stop and resume working when there is no one, thereby greatly improving the safety of the device.

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figure 1 shown, a food waste biodegradation device, characterized in that it includes: a box body 1, a pressing and lifting machine 2, a strain bacteria lifting machine 3, a grinder 4 and a mixer 5;

[0023] The box body 1 includes: a food waste treatment part 11, a strain bacteria treatment part 12 and a grinding and mixing part 13. A feeding hopper 111 is arranged above the food waste treatment part 11. The pressing and lifting machine 2 is arranged below the feeding hopper 111. A liquid leakage port 21 is arranged at the bottom of the pressing and lifting machine 2, and a discharge port 22 is arranged at the top. An oil-water separation device 112 is arranged below the liquid leakage port 21.

[0024] A biological strain container 121 is arranged inside the strain bacteria treatment part 12. The strain bacteria lifting machine 3 is arranged inside the biological strain container 121. The strain bacteria lifting machine 3 transports the strain bacteria into the mixer 5.

[0025] The grinder 4 is arranged inside the grinding and mixing part 13. The input port of the grinder 4 is connected to the discharge port of the pressing and lifting machine. Below the output port 41 of the grinder 4 is arranged the mixer 5. A slag discharge port 51 is arranged at the bottom of the mixer 5. Further, the mixer 5 can mix and stir the kitchen waste and the biological strain, and output through the slag discharge port 51.

[0026] Specifically, the pressing and lifting machine 2 includes: a pressing and lifting motor 23, a screw 24 and a screw barrel 25. The pressing and lifting motor 23 can drive the screw 24 to rotate inside the screw barrel 25. A plurality of leakage holes are arranged at the bottom of the screw barrel 25. When the pressing and lifting machine 2 is operating, during the lifting process of the screw 24, the kitchen waste will also be extruded, and its liquid component is extruded out and flows along the leakage holes through the liquid leakage port 21 to the oil-water separation device 112.

[0027] As Figure 2As shown, the oil-water separation device 112 is partitioned by a partition into an oil discharge chamber 1121 and a water discharge chamber 1122. The bottoms of the oil discharge chamber 1121 and the water discharge chamber 1122 are interconnected. An oil discharge port 1123 is provided on the side wall of the oil discharge chamber 1121. The side wall of the water discharge chamber 1122 is connected to a water discharge pipeline 1124 through a water discharge port. Thus, the oil and water filtered out from the bottom of the pressing and lifting machine can enter the oil-water separation device 112 for static separation. Among them, the oil overflows and discharges from the oil discharge port 1123 above the oil discharge chamber 1121, and the water discharges outward through the water discharge pipeline 1124.

[0028] As Figure 3 shown, the mixer 5 includes: a mixing motor 52, a mixing rotating shaft 53, and mixing rods 54. The mixing rods 54 are connected to the mixing rotating shaft 53. The mixing motor 52 can drive the mixing rotating shaft 53 to rotate. Thus, the kitchen waste can be fully stirred and mixed with the biological bacteria in the mixer 5.

[0029] Specifically, a weighing and output device 6 is further provided at the bottom of the mixer 5. The weighing and output device 6 includes a weighing module 61 provided at the bottom of the mixer 5 and a slag discharge valve 62 provided at the slag discharge port. The weighing module 61 can be linked with the slag discharge valve 62 to open and close the slag discharge port 51.

[0030] It should be noted that in this embodiment, the set weight value of the weighing module 61 for the inside of the mixer 5 is 160 Kg. Thus, when the total weight of the kitchen waste and the biological bacteria inside the mixer 5 reaches 160 Kg, the weighing module 61 can output an electrical signal and let the PLC controller 71 control the opening of the slag discharge valve 62 to output the fermented mixture after mixing treatment.

[0031] It should be further supplemented that the weight obtained by the weighing module 61 is the total weight of the mixer 5 and the internal stirring material. Thus, when the total weight of the mixer 5 changes and reaches the set 160 Kg, it is determined that the weight of the internal mixture reaches 160 Kg. At this time, the mixing motor 52 will temporarily stop working and the slag discharge valve 62 will be opened.

[0032] As Figure 4 shown, this food waste biodegradation device further includes a control system 7. The control system 7 includes: a PLC controller 71, a human body sensing module 72, and a weight sensor 73 provided inside the biological bacteria container;

[0033] The input end of the PLC controller 71 is electrically connected to the human body sensing module 72 and the weight sensor 73. The PLC controller 71 is controllably connected to the pressing and lifting machine 2, the grinder 4, the mixer 5, and the alarm 74.

[0034] In this embodiment, the human body sensing module 72 is arranged in the dumping sensing area above the lower hopper, and when a person transports kitchen waste into the dumping sensing area and dumps it downward through the lower hopper, the human body sensing module 72 can control the squeezing and lifting motor, the stirring motor, and the grinding motor to stop working through the PLC controller 71 until the person leaves the dumping sensing area for 5 seconds, and then the PLC controller controls each motor to resume working, thereby avoiding the safety hazard of people falling into the lower hopper when dumping or transporting kitchen waste, thereby ensuring the safety of people and machines.

[0035] In addition, the weight sensor 73 inside the biological strain container can sense the weight of the strain inside the biological strain container, and control the alarm 74 through the PLC controller 71 to prompt manual feeding.

[0036] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical solution of the utility model should be included in the protection scope of the utility model.
