Description

Technical Field

[0001] The present application relates to the technical field of restaurant kitchen waste treatment, and in particular to a novel restaurant kitchen waste centrifugal dehydrator. Background Art

[0002] Kitchen waste refers to food waste and food residues from households, schools, public canteens of units, and the catering industry. It is an important part of modern urban domestic waste. In the kitchen waste treatment industry, there is a method of using kitchen waste to breed black soldier flies. When black soldier flies grow up, they can directly become high-quality high-protein feed for poultry, or be made into protein powder as a raw material for feed formula. After research, it was found that kitchen waste with a moisture content of 60-70% is most conducive to the growth and development of black soldier flies, and the weight and body shape of black soldier flies are the best. However, the moisture content of most newly recycled kitchen waste is 80-90%, and it needs to be dehydrated before breeding.

[0003] There are generally two types of equipment used for dehydrating food waste on the market. One is a screw press. The rotating shaft with spiral blades continuously transports the material into the filter cartridge, and with the cooperation of the pressure mechanism at the end of the filter cartridge, the material in the filter cartridge is squeezed and dehydrated. The looseness of the dehydrated food waste meets the requirements for breeding black soldier flies, but most of its moisture content is maintained at 75%, which does not meet the requirements and needs to be dried or air-dried again. The other is a hydraulic extruder, which is equipped with a complete set of hydraulic and control systems. The material is first loaded into the filter cartridge, and then the pressure plate on one side of the filter cartridge enters the filter cartridge under the action of the hydraulic push rod and squeezes and dehydrates the material. The moisture content of the dehydrated food waste is mostly less than 60%, and its volume is in the form of large cakes. The looseness does not meet the requirements and needs to be crushed and dispersed again. The hydraulic system of the hydraulic extruder is relatively complex, and the production and subsequent maintenance costs are high.

[0004] As a black soldier fly breeding factory owner, we hope to obtain a dehydration equipment, the water content of the kitchen waste after dehydration is 60%-70%, the looseness is good, and the equipment has the characteristics of small size, low energy consumption, simple structure, long service life and easy maintenance. In order to meet the above requirements, it is necessary to design a centrifugal dehydrator with compact structure, continuous operation and high dehydration efficiency. Summary of the invention

[0005] In order to solve the problem that existing dehydration equipment does not meet the needs of food waste treatment, the present application provides a new type of food waste centrifugal dehydrator.

[0006] The present application provides a novel centrifugal dehydrator for restaurant kitchen waste, which adopts the following technical solution: A novel centrifugal dehydrator for food waste comprises a frame, wherein a lower cylinder and an upper cylinder are arranged on the frame, the lower cylinder is arranged on the frame, the upper cylinder is connected to the top of the lower cylinder, the lower cylinder and the interior of the upper cylinder are hollow structures, an upper cylinder cover is arranged on the top of the upper cylinder, a drain pipe is arranged at the bottom of the lower cylinder, a dehydrating device and a rotary support device are arranged inside the lower cylinder and the upper cylinder, the dehydrating device comprises an outer filter cartridge, an inner filter cartridge, a filter cartridge cover and a sealing cover, the outer filter cartridge is arranged on the rotary support device, a plurality of large circular holes for filtering water are penetrated on the outer filter cartridge, the inner filter cartridge is arranged in cooperation with the outer filter cartridge, a plurality of small circular holes for filtering water are penetrated on the inner filter cartridge, the filter cartridge cover is arranged at the top opening of the outer filter cartridge, the sealing cover is arranged at the connection between the outer filter cartridge and the rotary support device, and a motor for driving the dehydrating device and a brake device for braking are arranged on the frame.

[0008] When processing food waste, first, the operator opens the upper drum cover and the filter drum cover, and puts the food waste with a moisture content of 80-90% into the inner filter drum. Then the operator closes and locks the filter drum cover and the upper drum cover, and then starts the motor. The motor drives the rotary support device to start rotating, and then drives the dehydration device (including the outer filter drum and the inner filter drum) to rotate at high speed. This rotation process generates a strong centrifugal force, which squeezes and separates the food waste in the inner filter drum. Under the action of centrifugal force, the moisture in the food waste is thrown out and flows into the lower drum through the large circular holes on the outer filter drum and the small circular holes on the inner filter drum. As the dehydration process continues As the dehydration process progresses, more and more water accumulates in the lower cylinder, and eventually the water is discharged out of the machine body through the drain pipe at the bottom of the lower cylinder. When the dehydration process reaches the predetermined time or effect, the operator turns off the motor and waits for the dehydration device to gradually stop rotating. At this time, the operator can operate the brake device to reduce the waiting time for the filter cartridge to stop rotating naturally after power failure, so that it can stop rotating quickly. Finally, when the dehydration device stops rotating completely, the operator opens the upper cylinder cover and the filter cartridge cover again. The dehydrated food waste can be taken out together with the inner filter cartridge and dumped for treatment. The moisture content of food waste is usually between 60% and 70%, and the looseness is good, which is convenient for subsequent treatment or utilization.

[0009] Through the dehydration device, slewing support device and brake device, the equipment innovatively adopts the inner and outer double filter cartridge structure, which not only improves the dehydration efficiency, but also facilitates the loading and unloading of the inner filter cartridge and its materials. The motor is used as the power source of the equipment. It drives the slewing support device to drive the dehydration device to rotate at high speed. The equipment adopts a high speed of 950r / min, so that the high-humidity material in the filter cartridge is continuously centrifugally dehydrated and thrown out under the action of high-speed centrifugal force. The water is collected in the lower cylinder and finally flows out of the machine from the drain pipe at the bottom. This high-speed dehydration method is not Not only is the dehydration effect good, but the moisture content of the dehydrated food waste can be controlled between 60% and 70%, and the looseness of the waste is also good. At the same time, it is equipped with a brake device to realize manual control and rapid braking, which improves the operation convenience of the equipment and effectively shortens the equipment's stop waiting time. The equipment has the advantages of small size, small footprint, low power, energy saving, etc. It has a simple structure, reliable operation, long service life and easy maintenance.

The multi-level and multi-point support structure further enhances the load-bearing capacity and stability of the frame. At the same time, the combination of bowl-type shock absorbers and pier-type shock absorbers achieves a double shock-absorbing effect. The main function of the bowl-type shock absorber is to slow down and eliminate the vibration of the whole machine on the ground or the equipment installation platform during operation.

As the handle rotates, the torsion spring is gradually compressed and stores energy. At the same time, the brake operating rod at the bottom of the rotating shaft rotates together with the rotating shaft, which will drive the connecting rod and another brake operating rod to move together, and the brake distribution pin also rotates clockwise, so that the two brake shoes expand outward with the brake fixing pin as the center, and the friction material layer of the brake shoe and the inner side of the brake drum produce friction braking, the brake drum stops rotating, and the main shaft also stops rotating; when the brake needs to be released, the operator releases the handle, and under the reset action of the torsion spring and the two return springs, the brake shoe quickly returns to its initial position, and the friction material layer is out of contact with the inner side of the brake drum without producing a braking effect.

[0058] The implementation principle of a novel centrifugal dehydrator for food waste in the embodiment of the present application is as follows: when processing food waste, first, the operator opens the upper cylinder cover 6 and the filter cartridge cover 5-3, and puts the food waste with a moisture content of 80-90% into the inner filter cartridge 5-2. Then, the operator closes and locks the filter cartridge cover 5-3 and the upper cylinder cover 6, and then starts the motor 9, which drives the rotary support device 7 to start rotating, thereby driving the dehydration device 5 (including the outer filter cartridge 5-1 and the inner filter cartridge 5-2) to rotate at high speed. This rotation process produces The strong centrifugal force squeezes and separates the food waste in the inner filter cartridge 5-2. Under the action of the centrifugal force, the moisture in the food waste is thrown out and flows into the lower cylinder 3 through the large circular hole on the outer filter cartridge 5-1 and the small circular hole on the inner filter cartridge 5-2. As the dehydration process continues, more and more moisture accumulates in the lower cylinder 3. Finally, the moisture is discharged from the body through the drain pipe 13 at the bottom of the lower cylinder 3. When the dehydration process reaches the predetermined time or effect, the operator turns off the motor 9 and waits for the dehydration device 5 to gradually stop rotating.

[0059] At this time, the operator can operate the brake device 12 to reduce the waiting time for the filter cartridge to stop naturally after power failure. The operator turns the handle 12-13 clockwise to the left. The rotation of the handle 12-13 drives the shaft 12-10 connected thereto to rotate together. As the handle 12-13 rotates, the torsion spring 12-12 is gradually compressed and stores energy. At the same time, the brake operating rod 12-8 at the bottom of the shaft 12-10 rotates with the shaft 12-10, which will drive the connecting rod 12-9 and the other brake operating rod 12-8 to move together, and the brake distribution pin 12-6 also rotates clockwise, causing the two brake shoes 12-5 to expand outward with the brake fixing pin 12-3 as the center, and the friction material layer of the brake shoe 12-5 Friction braking is generated with the inner side of the brake drum 12-2, the brake drum 12-2 stops rotating, and the main shaft 7-1 also stops rotating; when the brake needs to be released, the operator releases the handle 12-13, and under the reset action of the torsion spring 12-12 and the two return springs 12-4, the brake shoe 12-5 quickly returns to its initial position, and the friction material layer is out of contact with the inner side of the brake drum 12-2 without producing a braking effect. Finally, when the dehydration device 5 completely stops rotating, the operator opens the upper drum cover 6 and the filter drum cover 5-3 again, and the dehydrated food waste can be taken out together with the inner filter drum 5-2 and dumped for treatment. The moisture content of the food waste is usually between 60% and 70%, and the looseness is good, which is convenient for subsequent treatment or utilization.

[0060] Through the arrangement of the dehydration device 5, the rotary support device 7 and the brake device 12, the equipment innovatively adopts the inner and outer double filter cartridge structure, which not only improves the dehydration efficiency, but also facilitates the loading and unloading of the inner filter cartridge 5-2 and its materials. The motor 9 serves as the power source of the equipment, and drives the rotary support device 7 to drive the dehydration device 5 to rotate at a high speed. The equipment adopts a high speed of 950r / min, so that the high-humidity material loaded in the filter cartridge is continuously centrifugally dehydrated and thrown out and collected in the lower cylinder 3 under the action of the high-speed centrifugal force, and finally flows out of the machine body from the drain pipe 13 at the bottom. This high speed The rapid dehydration method not only has a good dehydration effect, but also the moisture content of the dehydrated food waste can be controlled between 60% and 70%, and the looseness of the waste is also good. At the same time, it is equipped with a brake device 12 to achieve manual control and rapid braking, which improves the convenience of equipment operation and effectively shortens the equipment's stop waiting time. The equipment has the advantages of small size, small footprint, low power, energy saving, etc. It has a simple structure, reliable operation, long service life and easy maintenance. In addition to being used for dehydrating food waste, the equipment can also be used for the dehydration of other water-containing materials, and has broad application prospects and market value.
