Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen waste treatment equipment, specifically relating to a kitchen waste residue dewatering machine. Background Technology

[0002] As people's living standards continue to improve, the amount of food waste generated in daily life is also increasing, leading to greater attention being paid to its treatment. Currently, various countries have their own methods for food waste treatment. Regardless of the method used, the final waste treatment technology is largely similar: the first step is sorting the food waste to remove metal hardware, glass, plastic bags, etc. Then, through solid-liquid separation, the solid and liquid phases are processed according to various technologies. Most existing food waste treatment equipment consists of multi-process production lines composed of multiple large-scale devices. These systems are installed in large facilities such as food waste treatment stations or plants, and their processing technologies combine aerobic composting, anaerobic fermentation, and animal feed production, among others. This diversified approach not only improves the resource utilization rate of food waste but also allows it to be processed into various products.

[0003] An existing patent, titled "A High-Speed ​​Centrifugal Sand Desander for Food Waste" (publication number CN206356149U), describes a centrifugal sand desander that uses a quarter-helix spiral blade on a rotating shaft driven by a motor with a maximum speed of 1200 r / min. This high-speed rotation allows the shaft to centrifuge the food waste at high speed. However, the feed inlet of this centrifugal sand desander is located above the rotating shaft. Therefore, when food waste enters the centrifugal sand desander through the feed inlet, the high-speed rotation of the shaft can cause some waste to fly out of the centrifugal sand desander, resulting in a decrease in the sand desander's removal efficiency. Utility Model Content

[0030] Example 1

[0031] Please refer to Figure 1-4This embodiment provides a structure for a kitchen waste dewatering machine, which includes a feeding section and a high-speed centrifugal section, a transmission assembly, a filter screen 14, a liquid outlet 6, a slag outlet, and a feed inlet 5, all disposed within a housing 1. The housing 1 includes an upper housing 17 and a lower housing 9, which are detachably connected by a locking assembly. A sealing strip (not shown) is provided at the connection between the upper housing 17 and the lower housing 9. In this embodiment, the locking assembly is a bolt, allowing the housing 1 to be detachably divided into the upper housing 17 and the lower housing 9. The upper housing 17 is designed for easy cleaning of the interior of the casing 1. It also features lifting lugs that allow a crane to lift the dewatering machine, enabling it to move. The upper housing 17 is further divided into a fixed section and a movable section. The movable section is connected to the fixed section on one side via a hinge 8, and locked on the other side via a locking assembly. In this embodiment, the locking assembly is a tightening bolt with a knob. By using the hinge 8 to connect the fixed section and the movable section, the movable section can be easily opened, facilitating operator inspection of the dewatering machine.

[0032] Furthermore, the outer casing 1 is provided with a pushing part and a high-speed centrifugal part, and the pushing part and the high-speed centrifugal part are connected on the same axis. The pushing part pushes the kitchen waste to the high-speed centrifugal part, the high-speed centrifugal part centrifuges and dehydrates the kitchen waste, and the high-speed centrifugal part pushes the kitchen waste to the discharge port 7.

[0033] Furthermore, the pushing part is located below the feed inlet 5, and the pushing part is provided with a pushing screw shaft 3, and the pushing screw shaft 3 is provided with a first screw blade 12, and the pitch of the first screw blade 12 is 0.8 to 1.2 times the length L1 of the pushing screw shaft 3. In this embodiment, the pitch P1 of the first screw blade 12 is 1 times the length L1 of the pushing screw shaft 3.

[0034] Furthermore, the discharge port 7 is located at the end of the high-speed centrifuge section, which is equipped with a centrifugal spiral shaft 4. The centrifugal spiral shaft 4 is provided with a second spiral blade 11, and the pitch P2 of the second spiral blade 11 is 1.8 to 2.2 times the length L2 of the centrifugal spiral shaft 4. In this embodiment, the pitch of the second spiral blade 11 is twice the length L2 of the centrifugal spiral shaft 4. The pushing spiral shaft 3 and the centrifugal spiral shaft 4 are integrally formed. By setting the integrally formed structure of the pushing spiral shaft 3 and the centrifugal spiral shaft 4, the pushing spiral shaft 3 pushes the garbage to the high-speed centrifuge section by rotation, and then the garbage is dehydrated and deoiled by the rotation of the centrifugal spiral shaft 4. The garbage will not fly out of the inlet 5 due to the rotation of the centrifugal spiral section, thereby improving the efficiency of the dewatering machine in processing garbage.

[0035] In this embodiment, combined with Figure 2 and Figure 4It can be seen that the pitch P1 of the first helical blade 12 is smaller than the pitch P2 of the second helical blade 11. Therefore, it can be seen that the first helical blade 12 is a short-pitch structure and the second helical blade 11 is a long-pitch structure. The kitchen waste is first moved to the long-pitch structure by the rotation of the short-pitch structure, and then dehydrated and degreased by the rotation of the long-pitch structure. The rotation of the long-pitch structure can also push the kitchen waste towards the discharge port, thereby realizing the automated processing of kitchen waste.

[0036] Furthermore, the second spiral blade 11 is tangent to the filter screen 14. By setting the second spiral blade 11 and the filter screen 14 to be tangent, the food waste is not only subjected to the high-speed centrifugal action of the second spiral blade 11, but also to the squeezing action of the second spiral blade 11, so that the water and oil in the food waste are filtered more completely.

[0037] Furthermore, the filter screen 14 has evenly distributed mesh, and the filter screen 14 is fixedly connected to the outer shell 1 through the connecting post 15. The connecting post 15 is located on both sides inside the outer shell 1, and the filter screen 14 is suspended inside the outer shell 1 through the connecting post 15, thereby allowing space inside the outer shell 1 to store the filtered water and oil.

[0038] Furthermore, the filter screen 14 also includes an upper filter screen and a lower filter screen, wherein the upper filter screen and the lower filter screen are fixed by a locking assembly 16, and the lower half is fixedly connected to the outer casing 1 by a connecting post 15. In this embodiment, the locking assembly 16 is a locking bolt, and a plurality of connecting holes are provided at the connection between the upper filter screen and the lower filter screen. By inserting the locking bolt into the connecting holes, the upper filter screen and the lower filter screen are fixedly connected. Furthermore, due to the detachability of the locking bolt, the filter screen 14 can be cleaned better and more conveniently.

[0039] Furthermore, the outlet 6 is located below the filter screen 14, and the outlet 6 is a frustum structure with an inclined surface. By setting the outlet 6 as a frustum structure, the filtered water or oil can be collected better.

[0040] Furthermore, the discharge port 7 is connected to a solid impurity treatment device (not shown in the figure), and the inlet 5 is connected to a kitchen waste pumping device (not shown in the figure).

[0041] Furthermore, the transmission assembly includes a transmission motor 13 and a transmission belt assembly 2. The output end of the transmission motor 13 is connected to the transmission belt assembly 2, and the transmission belt assembly 2 is connected to the rotating shaft. That is, the transmission motor 13 drives the transmission belt assembly 2 to move, thereby driving the rotating shaft to rotate. In this embodiment, a belt drive is used instead of a speed reducer, so that the maximum separation speed of the device can be the same as the maximum speed of the transmission motor 13. Because the rotation speed of the rotating shaft is high during separation, the separation effect is good, and the solid phase separated from the slag outlet has a low moisture content, which is suitable for stacking and transportation.

[0042] The working principle of this utility model is as follows: First, the transmission component is started, and the kitchen waste pumping device is started, so that the kitchen waste enters through the feed port 5. Then, the first spiral blade 12 rotates to drive the kitchen waste to move towards the slag outlet. Next, under the action of the strong centrifugal force generated by the rotation of the coaxial second spiral blade 11, the oil-water mixture in the kitchen waste is quickly passed through the filter screen 14 and discharged from the liquid outlet 6 under the action of high-speed centrifugation. Larger insoluble impurities are trapped on the filter screen under the action of high-speed centrifugation to form a filter cake layer, which moves towards the slag outlet under the push of the second spiral blade 11 and is discharged through the discharge port 7, thus realizing the automatic and continuous liquid discharge and material discharge process.

[0043] Example 2

[0044] Please refer to Figure 5 The structure of the food waste dewatering machine in this embodiment is largely the same as that in Embodiment 1. Therefore, the same structure will not be described in detail in this embodiment. The difference between Embodiment 2 and Embodiment 1 is that the pushing part is provided with a pushing shaft, and a pushing plate 10 is slidably sleeved on the pushing shaft. The pushing plate 10 and the pushing shaft are also dynamically sealed to prevent food waste from entering the connection between the pushing plate 10 and the pushing shaft, which would result in incomplete pushing of food waste. In this embodiment, the pushing plate 10 is circular and fits the shape of the outer shell 1. The pushing plate 10 is also connected to the driving component 18 located outside the outer shell 1. The driving component 18 can be any structure that can make the pushing plate 10 slide along the pushing shaft. In this embodiment, the driving component 18 is a hydraulic cylinder drive.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
