Description

Technical Field

[0001] This invention relates to an automated waste cooking oil receiving box, belonging to the field of waste cooking oil treatment technology. Background Technology

[0002] Waste cooking oil has a high oil content and high acid value, which can easily clog urban pipes and increase the load on sewage treatment plants. However, oil extraction can reduce its environmental impact and improve economic efficiency.

[0003] Currently, the main source of waste cooking oil in China is the greasy floating matter from leftover food, which is then simply processed. Waste cooking oil usually contains a lot of impurities, especially at low temperatures, when it easily solidifies into a paste, which has a significant impact on subsequent processing.

[0004] Traditional urban kitchen waste oil receiving bins simply have a screen installed on the bin. The solid residue on the screen needs to be cleaned manually, and the screen is very easy to clog. At the same time, the odor cannot be effectively controlled, resulting in poor separation efficiency, large loss of crude oil, high labor intensity, poor working environment, and serious environmental pollution. Summary of the Invention

[0005] This invention provides an automated waste cooking oil receiving box that can automatically clean the filter basket without manual intervention, quickly separate waste cooking oil from debris, prevent waste cooking oil from solidifying in low-temperature environments, effectively control odor, and improve separation efficiency.

[0006] The technical solution of the present invention to achieve the above objectives is: an automated kitchen waste oil receiving box, characterized in that it includes a receiving box, a screen mechanism, a heating mechanism, a slag scraping mechanism, and a PLC controller; The receiving box is used to receive waste cooking oil containing impurities and to discharge the separated impurities and slurry. It includes a box body, an inlet cover, vertical partitions, and a screw conveyor for impurities. The box body includes a bottom plate, four side wall panels, and a top plate. The top plate has an inlet. The box body has a vertical partition on the rear side of the inlet, which divides the box body into an independent raw material compartment and a slurry compartment. The rear of the top plate has an odor inlet. The inlet cover is hinged to one side of the box body and covers the inlet. The inlet cover also has a hinge support on the hinged side. The outer side of the side wall panel has an outer support. One end of the hydraulic push rod is connected to the hinge support, and the other end is connected to the outer support on the side wall panel. The bottom plate of the box body has a slurry outlet. The screw conveyor for impurities is installed on one side of the box body. The screw conveyor for impurities, which slopes upward from front to back, has an outlet for impurities on the upper rear side and a drain outlet on the lower front side. The screen mechanism includes at least one set of guide rail supports and a filter basket. Each set of guide rail supports is fixed to the box wall panels on both sides of the box body. The filter basket includes a bottom plate and three side plates around the basket. The side plates are provided with at least one supporting edge. The supporting edges on both sides of the filter basket are set on the corresponding guide rail supports. The opening on the rear side of the filter basket is connected to the vertical partition plate to form a slurry tank. The bottom plate and the side plates are provided with screen holes. The bottom plate is provided with a discharge port on one side of the debris screw conveyor. The discharge port is connected to the inlet of the debris screw conveyor. The heating mechanism includes a steam pipe installed inside the box. The steam pipe passes through a vertical partition and is installed inside a filter basket. The steam pipe has multiple steam nozzles for heating, melting, and agitating waste cooking oil. The steam inlet of the steam pipe is located on the outer rear part of the box and is connected to an external steam pipe through a steam electronic control valve. The scraping mechanism includes a scraping motor, a moving rod, a scraper seat, and a scraper. The scraping motor is installed on the top plate of the box. The upper part of the moving rod is connected to the output side of the scraping motor, and the lower part has a scraper seat. A replaceable scraper is installed on the scraper seat. The bottom of the scraper is connected to the bottom plate of the basket to push the debris in the filter basket to the discharge hole and clean the screen holes. The PLC controller is electrically connected to the debris screw conveyor, hydraulic push rod, slag scraper motor, and steam electric control valve, and is used to control the operation of the debris screw conveyor, hydraulic push rod, slag scraper motor, and steam electric control valve.

[0007] The automated waste cooking oil receiving box of this invention adopts a receiving box, a screen mechanism, a heating mechanism, a slag scraping mechanism, and a PLC controller. The screen mechanism is set inside the box and forms a raw material bin and a slurry bin with the vertical partition inside the box. The waste cooking oil containing impurities first enters the receiving box through the automatically opened inlet, and is heated by direct steam injection through the steam pipe. At the same time, the steam agitates the waste cooking oil, accelerates its fluidity, liquefies solid oil, and promotes the rapid separation of solid impurities in the oil. This invention uses a filter basket to filter and remove impurities from liquid waste cooking oil before it enters the slurry tank. The filtered waste cooking oil then flows by gravity from the slurry outlet to the next processing unit. Vertical partitions address the issue of unfiltered waste cooking oil entering the slurry tank and, while improving maintainability, increase the capacity of the receiving box and slurry tank. Impurities inside the filter basket are promptly pushed to a debris screw conveyor by a scraper mechanism, where they are drained and discharged to external equipment. Simultaneously, the scraper mechanism automatically cleans the filter basket's screen holes, effectively preventing clogging and improving separation efficiency. This allows for rapid separation of waste cooking oil and impurities, enhancing the resource utilization of the oil. This invention achieves automatic impurity separation, effectively controls odors, prevents waste cooking oil from solidifying at low temperatures, has a high degree of automation, requires no manual intervention, and offers good environmental protection.

Detailed Implementation

[0016] See Figures 1-5 As shown, an automated kitchen waste oil receiving box of the present invention includes a receiving box, a screen mechanism, a heating mechanism, a slag scraping mechanism, and a PLC controller.

[0017] See Figures 1-5As shown, the receiving box of the present invention is used to receive waste cooking oil containing impurities and to discharge the separated impurities and slurry. The receiving box of the present invention includes a box body 1, an inlet cover plate 2, a vertical partition plate 16 and a debris screw conveyor 5. The box body 1 includes a bottom plate 1-2, four side wall plates 1-1 and a top plate 1-4, which can form a sealed box body to reduce the leakage of odor. The top plate 1-4 of the present invention is provided with a feed inlet. The box body 1 is provided with a vertical partition 16 on the rear side of the feed inlet, which divides the box body 1 into an independent raw material bin and a slurry bin. The vertical partition 16 is L-shaped, and the bottom support plate is connected to the opening of the bottom plate of the filter basket. The bottom of the vertical partition 16 is not connected to the bottom plate of the box, which can increase the capacity of the slurry bin. Waste kitchen oil is added to the raw material bin inside the box body 1 by unloading by the collection vehicle. It is not affected by the uneven addition of raw materials. After filtration and impurity removal, it is discharged from the slurry outlet. The rear part of the top plate 1-4 is provided with an odor interface 1-5, which can discharge the odor in the box body 1 to the odor treatment equipment for centralized treatment.

[0018] See Figure 1 , 2 As shown, the feed inlet cover 2 of this invention is hinged to the housing 1 and covers the feed inlet. Two hinges can be used to install the feed inlet cover 2 on one side of the housing 1. The feed inlet cover 2 also has a hinge support 2-1 on the hinged side. An outer support 1-11 is provided on the same outer side of the housing wall panel 1-1. One end of the hydraulic push rod 4 is connected to the hinge support 2-1, and the other end is connected to the housing wall panel 1-1. The feed inlet cover 2 is automatically opened and closed by the hydraulic push rod 4, which can reduce the leakage of odor from the receiving box. This invention can use one feed inlet cover 2 for individual opening and closing, or both can be opened and closed simultaneously, as shown below.

The filtered and impurity-removed liquid kitchen waste oil flows by gravity from the slurry outlet 1-3 to the next stage of processing unit. A debris screw conveyor 5 is installed on one side of the housing 1. The debris screw conveyor 5, which slopes upward from front to back, has a debris discharge port 5-1 on its upper rear side and a drain outlet 5-2 on its lower front side. The debris filtered by the filter basket 12 is discharged from the receiving box through the debris screw conveyor 5. The debris screw conveyor 5 of this invention is a conventional screw conveyor. The inclination angle of the debris screw conveyor 5 is between 5 and 10°. For example, if the inclination angle of the debris screw conveyor 5 is 8°, the debris can be drained during the conveying process, which can reduce the water content and oil content of the debris and improve resource utilization. The screw conveyor 5 of this invention is a shaftless screw conveyor. A cleaning port is provided at the top of the screw conveyor 5, through which hot water or steam can be introduced. Cleaning water can be discharged from the drain outlet 5-2, allowing for regular cleaning of the screw conveyor 5 and preventing screw entanglement and filter screen 11 clogging. The screw conveyor 5 of this invention uses both forward and reverse rotation; when material jamming occurs, the screw is reversed to effectively clear the material.
