Description

Technical Field

[0001] This utility model belongs to the field of solid-liquid separation of kitchen waste, and in particular relates to a centrifugal dewatering machine for kitchen waste. Background Technology

[0002] In recent years, the catering industry has continued to expand, with a rapid increase in the number of operating locations, resulting in a significant increase in the total amount of food waste. According to environmental protection policies, food waste is being reduced, recycled, and treated professionally through sorting, dehydration, and other processes to gradually achieve reduction, resource recovery, and harmlessness. Currently, the dehydration process for food waste mainly employs two technological pathways: mechanical extrusion and centrifugal separation. However, in practical applications, extrusion dehydration technology is prone to internal caking and blockage when processing highly viscous substances such as animal fats, requiring frequent shutdowns for cleaning and maintenance. While centrifugal dehydration has high separation efficiency, it lacks continuous dehydration; after each processing cycle, solid residue must be manually removed before dehydration can continue, thus affecting the overall dehydration efficiency of food waste.

[0003] To address the issue of centrifugal dewatering machines lacking continuous operation, Chinese patent CN115254450A discloses a centrifugal dewatering device with continuous operation function for kitchen waste. Through optimized structural design, it achieves uninterrupted processing. However, in actual application, when the device is running at high speed and materials are continuously fed in, there is a problem of random splashing of kitchen waste juice in the feed inlet area. This sudden liquid splashing phenomenon not only pollutes the operating area environment but may also cause workers to become contaminated, directly affecting the user experience and convenience of daily operation of the equipment. Utility Model Content

The dewatering cylinder includes a receiving tray, an inner cylinder, and a filter cylinder, all located on the same central axis. The top of the inner cylinder is connected to the receiving tray, and the inner cylinder is connected to the drive motor through a bushing. A filter cylinder is provided on the outside of the inner cylinder. The upper end of the filter cylinder is provided with a feed inlet, which is located directly above the receiving tray. Several blades are provided on the top of the inner wall of the filter cylinder, which are evenly distributed in the circumferential direction. The distance from the blades to the central axis of the dewatering cylinder is greater than the radius of the feed inlet outlet. Multiple rows of holes are evenly distributed on the surface of the filter cylinder. A water collection trough is arranged around the bottom outer side of the filter cylinder. An inner cylinder is provided on the water collection trough. The diameter of the feed inlet is greater than the diameter of the feed outlet.

[0006] Furthermore, both the inner cylinder and the filter cylinder are hollow frustum-shaped structures, and the receiving tray is a conical structure.

[0007] Furthermore, the bottom of the receiving tray is connected to the top of the inner cylinder via a third fixing member, the inner side of the inner cylinder is connected to the bushing via a second fixing member, the outer side of the inner cylinder is connected to the inner side of the filter cartridge via a first fixing member, and the bushing is sleeved on the drive motor.

[0008] Furthermore, the water collection tank includes an outer ring, an inner ring, and a drain outlet. An outer ring is fitted around the outer side of the inner ring, and the bottom of the inner ring connects to the bottom of the outer ring to form a channel. The height of the inner ring is greater than the height of the outer ring. The drain outlet is located on the outer ring and communicates with the channel. An inner cylinder is inserted into the outer ring. A conical ring is located on the inner ring, with its bottom diameter equal to the diameter of the inner ring. The height of the inner ring is greater than the bottom surface of the filter cartridge, and its diameter is greater than the bottom diameter of the filter cartridge.

[0009] Furthermore, a flow guide is provided at the bottom of the water collection tank. The flow guide has an inverted truncated cone structure, and the diameter of the upper opening of the flow guide is equal to the diameter of the inner ring of the water collection tank.

[0010] Furthermore, the inner cylinder is provided with an upper port at the top, the upper port being an inverted frustum structure, and the upper port of the inner cylinder is nested and connected to the feed port.

[0011] Furthermore, a water-blocking ring is provided on the lower outer side of the filter cartridge, and the outer diameter of the water-blocking ring is larger than the inner diameter of the water collection tank.

[0012] Furthermore, a shock absorber is also provided on the horizontal support, and the shock absorber is connected to the drive motor.

[0013] Furthermore, an electronic controller is installed on the outer casing frame, and the electronic controller is connected to the drive motor.

[0014] Furthermore, the outer casing frame is a semi-enclosed structure, and a collection bucket is also provided inside the outer casing frame, with the collection bucket located directly below the flow guide.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a drive motor to drive the dewatering cylinder to rotate at high speed. The dewatering cylinder includes a filter cylinder and an inner cylinder, and a material channel is formed between the filter cylinder and the inner cylinder. The blades, which are evenly distributed along the circumferential direction on the top of the inner wall of the filter cylinder, rotate at high speed with the filter cylinder. The blades draw the air above the feed inlet of the dewatering cylinder into the dewatering cylinder, thereby forming a top-down airflow curtain. When the dewatering cylinder rotates at high speed to centrifuge and dewater the kitchen waste, the airflow curtain blocks the residue and juice that are rebounded by the inner wall of the filter cylinder during the dewatering process, thereby solving the problem of residual juice splashing in the feed inlet area.

[0017] 2. The dewatering cylinder of this utility model adopts a double-layer conical structure. The double-layer conical structure can significantly optimize the dewatering efficiency, allowing the material to move along the axial direction under the action of centrifugal force. The inclined surface of the cone is more conducive to the downward sliding of the material, avoiding accumulation at the top of the dewatering cylinder or near the holes of the filter cylinder, and reducing the risk of clogging.

[0018] 3. This utility model guides the concentrated feeding of kitchen waste by setting the feed inlet as an inverted truncated cone structure, reducing the splashing of residue and juice during feeding. Furthermore, the coaxial arrangement of the feed inlet, drive motor, and dewatering drum optimizes the transfer path of kitchen waste, thereby further improving the splash-proof performance.

[0019] 4. This utility model has a water collection tank arranged around the outside of the bottom of the filter cylinder. The juice generated by centrifugal force is discharged through the holes on the surface of the filter cylinder and, together with the water-blocking ring set at the bottom of the filter cylinder, makes the juice flow into the water collection tank. By setting the water-blocking ring, the juice is directed to flow into the water collection tank, which further avoids the juice splashing and prevents the juice from flowing into the collection bucket, effectively reducing the moisture content of the residue.

[0020] 5. This utility model has a simple structure, high internal space utilization, and convenient operation. The residue after dehydration is automatically collected into the collection bin. It is particularly suitable for reducing the amount of kitchen waste in canteens with a large number of people. It can continuously reduce the amount of kitchen waste and reduce the pollution to the environment during the collection and transportation of kitchen waste. In addition, the motor power of this utility model is less than the working power of existing motors, making this device more energy-efficient. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0033] Detailed implementation method: See Figure 1-8This embodiment describes a centrifugal dewatering machine for food waste, comprising a casing frame 1, a dewatering cylinder 4, and a drive motor 6. The casing frame 1 has a feed inlet 3 at its top, which is a truncated cone structure to facilitate the entry of food waste into the equipment and guide its descent. A horizontal support is installed inside the casing frame 1, and the drive motor 6 is mounted on the horizontal support. The top of the drive motor 6 is connected to the dewatering cylinder 4, and the drive motor 6 drives the dewatering cylinder 4 to rotate at high speed, thereby centrifugally dewatering the food waste. The feed inlet 3, the dewatering cylinder 4, and the drive motor 6 are coaxially arranged to reduce rotational imbalance. This reduces mechanical wear and noise, thereby improving equipment stability and extending its service life. The dewatering cylinder 4 includes a receiving tray 46, an inner cylinder 47, and a filter cylinder 51. The receiving tray 46, inner cylinder 47, and filter cylinder 51 are located on the same central axis, ensuring effective power transmission. The top of the inner cylinder 47 is connected to the receiving tray 46, and the inner cylinder 47 is connected to the drive motor 6 through a bushing 48. The filter cylinder 51 is located outside the inner cylinder 47, with a material flow channel between the inner cylinder 47 and the filter cylinder 51. The upper end of the filter cylinder 51 is provided with a feed inlet 45, which is located directly above the receiving tray 46, thus ensuring... To ensure that kitchen waste can smoothly enter the filter cartridge 51 and inner cylinder 47 from the inlet 3 and inlet 45 for dewatering, several blades 44 are evenly distributed circumferentially on the top of the inner wall of the filter cartridge 51. The distance from the blades 44 to the central axis of the dewatering cylinder 4 is greater than the radius of the outlet end of the inlet 3. The blades 44 inside the filter cartridge 51 draw air above the inlet 45 into the dewatering cylinder 4, thus forming an air curtain. Therefore, during the dewatering process of kitchen waste, residual juice that is bounced back against the inner wall of the filter cartridge 51 and splashes towards the inlet 3 will be affected by the air curtain and return to the filter cartridge 51, thus effectively solving the problem of residual juice splashing at the inlet 3. Multiple rows of holes 43 are evenly distributed on the surface of filter cartridge 51. Under the action of centrifugal force, the liquid in the kitchen waste is thrown out of filter cartridge 51 through the holes 43, thereby achieving dehydration. A water collection tank 8 is arranged around the bottom outer side of filter cartridge 51. The liquid thrown out of filter cartridge 51 is collected through water collection tank 8 for subsequent processing. An inner cylinder 2 is arranged on the water collection tank 8. The liquid generated by the kitchen waste under centrifugal force falls onto the inner wall of inner cylinder 2 through the holes on filter cartridge 51 and flows along the inner wall of inner cylinder 2 to water collection tank 8 for collection. The diameter of the feed inlet 45 is larger than the diameter of the feed port 3, thereby ensuring that the kitchen waste accurately reaches the dehydration cylinder 4 after entering through feed port 3.

[0034] The working principle of this utility model is as follows:

[0035] The drive motor 6 drives the dewatering cylinder 4 to rotate at high speed. The blades 44 inside the filter cylinder 51 draw air from above the inlet 45 into the dewatering cylinder 4, thus forming an air curtain. The sorted kitchen waste enters through the inlet 3 and falls onto the receiving tray 46. The kitchen waste is affected by centrifugal force and detaches from the receiving tray 46, falling onto the inner wall of the filter cylinder 51 through the gap between the blades 44 and the receiving tray 46. Due to the high speed of the dewatering cylinder 4, the kitchen waste is easily bounced when it falls onto the inner wall of the filter cylinder 51. When the residual juice bounced off the inner wall of the filter cylinder 51 splashes towards the inlet 3, it is affected by the air curtain and returns to the filter cylinder 51. The residual juice that returns to the filter cylinder 51 is dewatered together with the rest of the kitchen waste. Under the action of centrifugal force, the liquid in the kitchen waste falls through the holes 43 on the surface of the filter cylinder 51 onto the inner wall of the inner cylinder 2, and flows along the inner wall of the inner cylinder 2 to the water collection tank 8 below for collection and subsequent processing.

[0036] Both the inner cylinder 47 and the filter cylinder 51 are hollow truncated cone structures, forming a downward-sloping channel between the inner cylinder 47 and the filter cylinder 51. The receiving tray 46 is a conical structure, thereby quickly guiding the garbage falling from the feed inlet 3 to the opening end of the inner cylinder 47 through centrifugal force, reducing material stagnation.

[0037] The bottom of the receiving tray 46 is connected to the top of the inner cylinder 47 via a third fixing member 50. The inner side of the inner cylinder 47 is connected to the bushing 48 via a second fixing member 49. The outer side of the inner cylinder 47 is connected to the inner side of the filter cartridge 51 via a first fixing member 42. The bushing 48 is sleeved on the drive motor 6, thereby enabling the drive motor 6 to rotate and drive the bushing 48 to rotate. The bushing 48 drives the inner cylinder 47 to rotate via the second fixing member 49. The inner cylinder 47 drives the receiving tray to rotate via the third fixing member 57. The inner cylinder 47 drives the filter cartridge 51 to rotate via the first fixing member 42, causing the dewatering cylinder 4 to rotate at high speed.

[0038] The water collection tank 8 includes an outer ring 81, an inner ring 82, and a drain outlet 84. The outer ring 81 is fitted around the inner ring 82. The bottom of the inner ring 82 is connected to the bottom of the outer ring 81, forming a channel. The height of the inner ring 82 is higher than the height of the outer ring 81. The drain outlet 84 is located on the outer ring 81 and communicates with the channel. An inner cylinder 2 is inserted into the outer ring 81. A conical ring 83 is located on the inner ring 82. Under centrifugal force, the liquid in the kitchen waste passes through the pores on the surface of the filter cartridge 51. 43 falls onto the inner wall of the inner cylinder 2, and the liquid falls along the inner wall of the inner cylinder 2 into the channel, and is discharged through the drain outlet 84 of the water collection tank. The bottom diameter of the conical ring 83 of the water collection tank is equal to the diameter of the inner ring 82 of the water collection tank. Since the top diameter of the conical ring 83 is larger than the bottom diameter of the dehydration cylinder 4, it can evenly disperse the liquid to the inner side of the water collection tank 8, preventing the liquid from directly impacting the bottom or outside of the water collection tank 8, thereby reducing liquid splashing. The height of the inner ring 82 of the water collection tank is higher than the bottom surface of the filter cylinder 51, and the diameter of the inner ring 82 of the water collection tank is larger than the bottom diameter of the filter cylinder 51, thereby ensuring that all the liquid thrown out from the bottom of the filter cylinder 51 can enter the channel, and there will be no situation where the liquid flows out of the channel.

[0039] The bottom of the water collection tank 8 is equipped with a flow guide hood 9, which is an inverted truncated cone structure. The diameter of the upper opening of the flow guide hood 9 is equal to the diameter of the inner ring 82 of the water collection tank, thereby effectively receiving the dehydrated kitchen waste discharged from the water collection tank 8. When the dehydration cylinder 4 rotates at high speed, the kitchen waste is thrown against the inner wall of the filter cylinder 51 under the action of centrifugal force. The liquid in it is thrown out through the holes 43 on the surface of the filter cylinder 51 and flows into the water collection tank 8. The dehydrated kitchen waste moves downward along the inner wall of the filter cylinder 51 under the action of centrifugal force and is finally discharged through the bottom of the filter cylinder 51. The flow guide hood 9 can also play a certain sealing role, reducing the splashing of waste during the discharge process.

[0040] The inner cylinder 2 is provided with an upper port, which is an inverted truncated cone structure. The upper port of the inner cylinder 2 is nested and connected to the feed inlet 3, which effectively guides the kitchen waste from the feed inlet 3 into the inner cylinder 2. At the same time, it plays a certain sealing role to prevent the waste from leaking or splashing during the process of entering the inner cylinder 2, thereby improving the operating efficiency and cleanliness of the equipment.

[0041] A water-blocking ring 41 is provided on the lower outer side of the filter cartridge 51. The outer diameter of the water-blocking ring 41 is larger than the inner diameter of the water collection tank 8, thereby preventing the liquid generated during the dehydration process from entering the inner ring 82 of the water collection tank and being discharged through the guide hood 9 with the dehydrated kitchen waste, thus affecting the dehydration effect.

[0042] The horizontal support is also equipped with a shock absorber 7, which is connected to the drive motor 6. During the dehydration process, the drive motor 6 drives the dehydration cylinder 4 to rotate at high speed, which will generate large vibrations. The shock absorber 7 can effectively buffer these vibrations, reduce the impact of vibrations on other parts of the equipment, and reduce the risk of wear and damage to the equipment.

[0043] An electronic controller 5 is installed on the outer casing frame 1. The electronic controller 5 is connected to the drive motor 6. The electronic controller 5 is installed on the outer casing frame 1 so that the operator can control the drive motor 6 from outside the equipment. Through the electronic controller 5, a series of operations such as starting, stopping and speed adjustment of the drive motor 6 can be realized without direct contact with the drive motor 6, which improves the convenience and safety of operation.

[0044] The outer frame 1 is a semi-enclosed structure. The outer frame 1 is also equipped with a collection bucket 10. The lower part of the outer frame 1 is closed on three sides and open on one side. The collection bucket 10 is located directly below the flow guide 9. The collection bucket 10 is placed below the flow guide 9 through one side opening and is used to collect the dehydrated kitchen waste discharged by the flow guide 9.

[0045] Food waste enters the equipment through inlet 3. The inverted cone structure of inlet 3 guides the waste to fall onto the receiving tray 46. The food waste on the receiving tray 46 is detached by centrifugal force, reducing material stagnation. It falls from the gap between the blades 44 and the receiving tray 46 onto the inner wall of the filter cartridge 51. A downward-sloping channel is formed between the inner cylinder 47 and the filter cartridge 51. The food waste is dehydrated in the channel by centrifugal force. The blades 44 on the inner wall of the filter cartridge 51 form an air curtain when the dehydration cylinder 4 rotates at high speed, preventing residual juice rebounding from the inner wall of the filter cartridge 51 from splashing back to the inlet, effectively solving the problem of splashing at the inlet during the dehydration process. Under the action of centrifugal force, the liquid in the food waste is thrown out through the holes 43 on the surface of the filter cartridge 51, enters the inner cylinder 2, and flows along its inner wall to the water collection tank 8. The water collection tank 8 ensures that the liquid is effectively collected and discharged. The water tank drain outlet 84 discharges the dehydrated kitchen waste, which moves downward along the inner wall of the filter cylinder 51 under centrifugal force and is finally discharged through the bottom of the filter cylinder 51. It is then guided to the collection bucket 10 by the guide hood 9. The inverted cone structure of the guide hood 9 effectively receives the waste and reduces splashing during the discharge process. The upper port of the inner cylinder 2 is nested with the feed inlet 3, which guides the waste into the inner cylinder while preventing leakage and splashing. The water baffle ring 41 on the lower outer side of the filter cylinder 51 prevents liquid from entering the inner side of the water collection tank 8 and being discharged with the dehydrated kitchen waste, thus affecting the dehydration effect. The shock absorber 7 on the horizontal support can buffer the vibration generated by the high-speed rotation of the drive motor 6, reduce the impact on the equipment parts, and reduce the risk of wear and damage. The operator controls the start, stop, and speed adjustment of the drive motor 6 through the electronic controller 5 outside the equipment, which improves the convenience and safety of operation.

These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification.
