A kitchen waste treatment process and system

Abstract

The present invention discloses a kitchen waste treatment process and system, including a first treatment tank. A feeding frame is arranged on the upper surface of the first treatment tank. Through the arranged anti-blocking component and the primary solid-liquid separation component, when the first electric push rod is started, the blanking plate can be opened to move the kitchen waste downward to the surface of the screening plate. Then, as the first electric push rod drives the clamping plate to squeeze the pressing plate downward, the surface of the kitchen waste is squeezed by the pressing plate to squeeze out the liquid inside the kitchen waste. At the same time, the kitchen waste may block the screening holes on the surface of the screening plate. Then, the second electric push rod is started to make the sliding inclined plate and the insertion column slide upward, pushing the blockage inside the screening holes upward. Then, when the first motor is started, the pushing plate can slide along the upper surface of the screening plate, thereby pushing the blockage into the separation tank.

Description

Technical Field

[0001] The present invention relates to the field of kitchen waste treatment, and specifically to a kitchen waste treatment system. Background Art

[0002] Nowadays, the amount of kitchen waste generated by the catering industry is increasing day by day. Kitchen waste contains food residues, oil, water, plastic bags, etc. The types of waste are complex and diverse. Moreover, due to the coexistence of solid and liquid in kitchen waste, it is very easy to ferment and deteriorate to produce peculiar smells, causing pollution to the atmosphere. Therefore, it is necessary to properly treat it to avoid environmental pollution, and it is necessary to classify and treat solid and liquid impurities so that various types of waste can be reasonably utilized after treatment to improve the efficiency of resource recycling.

[0003] According to Chinese Patent No. CN114260285A, a kitchen waste treatment system and method are disclosed. The present invention is applicable to the technical field of kitchen waste treatment, and provides a kitchen waste treatment system and method, including a support, on which a treatment box is arranged. A crushing box is arranged on one side of the treatment box, a solid-liquid separator is arranged below the crushing box, and an oil-water separator is arranged on one side of the solid-liquid separator; when it is necessary to treat kitchen waste, a sieve plate separates the waste and liquid; then, the waste flows into the crushing box for crushing treatment, and then the treated mixture flows into the solid-liquid separator, while the sieved liquid flows into the filtration box for filtration, and then the filtered liquid enters the liquid storage tank for storage; finally, the solid-liquid separator dehydrates the crushed mixture, and the separated oil-water mixture is output to the oil-water separator, while the separated solid matter remains in the sieve cylinder. The present invention realizes an integrated treatment process for kitchen waste, separating kitchen waste into solid residues, water and oil, which greatly facilitates subsequent treatment.

[0004] In the solution, due to the long-term use of the sieve plate, continuously screening and filtering kitchen waste, the sieve holes on the surface of the sieve plate may become blocked. During cleaning, it is necessary to manually clean the sieve plate and the cleaning process is relatively cumbersome, making it impossible to quickly and effectively separate the liquid and solid, thus reducing the treatment efficiency of the device for kitchen waste.

[0016] The present invention also discloses a usage process of a kitchen waste treatment system. By using the above-mentioned kitchen waste treatment system, it includes the following steps:

[0017] S1. Kitchen waste enters the interior of the first treatment tank through the feeding frame, and then the large-piece kitchen waste is screened by the primary screening component. The large-piece kitchen waste and the small-piece kitchen waste are screened out. The small-piece kitchen waste will fall onto the surface of the crushing component, and the small-piece kitchen waste is crushed by the crushing component.

[0018] S2. After the crushing is completed, by starting the primary solid-liquid separation component, the crushed kitchen waste falls onto the surface of the screening plate, and then the pressing plate moves downward to squeeze the kitchen waste, performing a preliminary solid-liquid separation on the kitchen waste. The separated liquid will flow into the interior of the liquid storage tank.

[0019] S3. Then, start the second electric push rod in the anti-blocking component to make the sliding inclined plate and the insertion post slide upward and insert into the screening holes on the surface of the screening plate. Then, start the first motor on one side to make the push plate slide, so as to push the kitchen waste on the surface of the screening plate into the inclined material channel and then slide into the separation cylinder inside the separation box.

[0020] S4. When the kitchen waste moves into the separation cylinder, start the third motor to make the separation cylinder rotate. The liquid in the kitchen waste in the separation cylinder is thrown out by the centrifugal force of rotation and thrown out through the through holes on the surface of the separation cylinder. Then, start the liquid extraction pump on one side to pump the liquid into the liquid storage tank.

[0021] S5. After the secondary separation is completed, start the material extraction component to transport the kitchen waste to the storage box. Then, when it is necessary to clean the kitchen waste, the fourth electric push rod can be started to drive the top plate to slide upward and move the kitchen waste upward. At the same time, the oil extraction pump can be started to extract the oil stains floating on the liquid. As the liquid drops, the third electric push rod can be started to extend the telescopic pipe to extract the oil stains at different heights. The liquid at the bottom is discharged by opening the valve on the surface of the drain pipe.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. With the anti-blocking component and the primary solid-liquid separation component set, when the first electric push rod starts, the feeding plate can be opened to move the kitchen waste downward to the surface of the screening plate. Then, as the first electric push rod drives the clamping plate to squeeze the pressing plate downward, the surface of the kitchen waste is squeezed by the pressing plate to squeeze out the liquid inside the kitchen waste. At the same time, the kitchen waste may block the screening holes on the surface of the screening plate. Then, start the second electric push rod to make the sliding inclined plate and the inserting column slide upward to push the blockage inside the screening holes upward. Then, start the first motor to make the pushing plate slide along the upper surface of the screening plate, so as to push the blockage into the separation box. When the screening plate is used for a long time, the situation of the screening plate being blocked is avoided, replacing the manual cleaning operation process. At the same time, the solid and liquid can be quickly separated, thus greatly improving the processing efficiency of the device for kitchen waste;

[0024] 2. Through the setting of the primary solid-liquid separation component and the secondary solid-liquid separation component, through two solid-liquid separation operations. First, the kitchen waste is squeezed to separate the internal liquid through the screening plate, and then it will flow into the liquid storage pipe. Then, when the kitchen waste is transported into the separation cylinder, by rotating the separation cylinder, the liquid inside the kitchen waste is separated by the centrifugal force generated during rotation. Through the two-sided solid-liquid separation operation, the liquid in the kitchen waste is greatly separated, improving the processing effect of the device on kitchen waste;

[0025] 3. Through the setting of the primary screening component and the crushing component, through the primary screening component, large pieces of kitchen waste can be filtered out by the screening rollers. The spacing between the screening rollers does not allow large pieces of kitchen waste to move downward, and small pieces of kitchen waste will fall through the direct spacing between the screening rollers. Then, the kitchen waste is crushed by the crushing rollers to facilitate the subsequent solid-liquid separation operation. Large pieces of kitchen waste will move into the first collection box, so that large pieces of kitchen waste will not affect the subsequent solid-liquid separation operation, improving the processing quality of the device;

[0026] 4. Through the set material extraction component, start the rotating motor to drive the spiral conveying blade to rotate. The kitchen waste inside the separation cylinder enters the material extraction cylinder through the feeding groove, and then the kitchen waste is input into the storage box through the feeding inclined pipe. Then, start the fourth electric push rod to drive the top plate to move upward, facilitating the staff to clean the internal kitchen waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In this embodiment: The kitchen waste is conveyed into the interior of the separation cylinder 901. Then, by starting the third motor 903, the driving column is driven to rotate. The support column and the upper separation cylinder 901 above are driven to rotate through the third belt pulley. When the separation cylinder 901 rotates, the liquid inside the kitchen waste flows out through the through holes on the surface of the separation cylinder 901 by centrifugal force. Then, the liquid extraction pump 905 is started to pump the oil-water mixture into the storage tank 7 through the liquid extraction pipe 904. At the same time, as the separation cylinder 901 rotates, the brush plate 906 can continuously rub the inner side wall of the separation cylinder 901, avoiding the blockage of the through holes on the side surface of the separation cylinder 901. After the oil-water mixture is solid-liquid separated twice, it will flow into the storage tank 7. The third electric push rod 703 can be started to drive the telescopic pipe 702 to extend downward, so that one end of the telescopic pipe 702 is at the top layer of the liquid. According to the principle that oil and water always float on the water surface, the oil pump 701 is started to pump out the oil and water, and then the valve on the surface of the drain pipe is started to drain the water at the bottom.

The material extraction assembly 10 includes a material extraction cylinder 1001 fixedly installed on the upper surface of the converging groove seat 902. A feeding groove 1002 is provided at the bottom of the surface of the material extraction cylinder 1001. A spiral conveyor blade 1003 is rotatably connected inside the material extraction cylinder 1001. A rotary motor 1004 is fixedly installed on the top of the material extraction cylinder 1001 through a housing.

[0063] In this embodiment: after the secondary solid-liquid separation is completed, the kitchen waste enters the feeding cylinder 1001 from the feeding trough 1002 at the bottom of the feeding cylinder 1001. Then, the rotating motor 1004 is started to drive the spiral conveying blade 1003 to rotate, so as to convey the kitchen waste upward and convey it to the storage tank 1006 through the feeding inclined pipe 1005. The converging trough seat 902 arranged at the bottom can converge the kitchen waste towards the bottom, so that the kitchen waste can be continuously conveyed. When it is necessary to clean the kitchen waste inside the storage tank 1006, the fourth electric push rod 1008 can be started to drive the top plate 1007 to move upward, which is convenient for the staff to clean the kitchen waste.

[0064] The following combines the above-mentioned kitchen waste treatment system to provide a use process of the kitchen waste treatment system, which specifically includes the following steps:

[0065] S1. The kitchen waste enters the interior of the first treatment tank 1 through the feeding frame 2, and then the large pieces of kitchen waste are screened by the primary screening component 3. The large pieces of kitchen waste and the small pieces of kitchen waste are screened out. The small pieces of kitchen waste will fall onto the surface of the crushing component 4, and the small pieces of kitchen waste are crushed by the crushing component 4;

[0066] S2. After the crushing is completed, the kitchen waste after crushing is dropped onto the surface of the screening plate 501 by starting the primary solid-liquid separation component 5. Then, the pressing plate 507 moves downward to squeeze the kitchen waste, and the primary solid-liquid separation of the kitchen waste is carried out. The separated liquid will flow into the interior of the liquid storage tank 7;

[0067] S3. Then, the second electric push rod 605 in the anti-blocking component 6 is started to make the sliding inclined plate 601 and the inserting column 603 slide upward and insert into the screening holes 502 on the surface of the screening plate 501. Then, the first motor 613 on one side is started to make the push plate 611 slide, so as to push the kitchen waste on the surface of the screening plate 501 into the inclined material channel and then slide into the separation cylinder 901 inside the separation box 8;

[0068] S4. When the kitchen waste moves into the separation cylinder 901, the third motor 903 is started to make the separation cylinder 901 rotate. The liquid in the kitchen waste in the separation cylinder 901 is thrown out by the centrifugal force of rotation, and is thrown out through the through holes on the surface of the separation cylinder 901. Then, the liquid pumping pump 905 on one side is started to pump the liquid into the liquid storage tank 7.

[0069] After the secondary separation is completed, the food waste is conveyed into the storage tank 1006 by starting the feeding component 10. Then, when it is necessary to clean the food waste, the fourth electric push rod 1008 can be started to drive the top plate 1007 to slide upward and move the food waste upward. At the same time, the oil pump 701 can be started to extract the oil stains floating on the liquid. As the liquid level drops, the third electric push rod 703 can be started to extend the telescopic pipe 702, so as to extract the oil stains at different heights. The liquid at the bottom is discharged by opening the valve on the surface of the drain pipe.
