Description

Technical Field

[0001] The present application relates to the technical field of resource treatment of organic waste, and in particular to a device capable of automatically unloading kitchen waste grease contained in a grease barrel and a method of using the device. Background Art

[0002] Waste cooking oil refers to waste edible animal and plant oils and wastewater containing edible animal and plant oils generated in catering services, food production and processing, and food preparation and sale activities other than daily life. Waste cooking oil is a by-product of the catering industry. It not only has a high content of free fatty acids, but also contains oxidation products such as aldehydes, ketones and polymers. It is inedible waste oil.

[0003] By using mature and reliable treatment processes and building a restaurant waste oil treatment project with advanced technology and scientific management, we can turn waste into treasure while ensuring people's health. This not only meets the needs of urban construction, but is also an important part of developing a circular economy. This is conducive to the resource utilization and harmless treatment of restaurant waste oil, improving the urban living environment, and complying with the national principles of "harmlessness, reduction, and resource utilization" for the disposal of domestic waste.

[0004] Waste cooking oil has the characteristics of complex sources, diverse ingredients, poor physical properties, and serious health and environmental hazards. Therefore, there are strict requirements for the collection, transportation, and treatment of waste cooking oil at the source to ensure that no environmental pollution is caused at each link.

[0005] At present, waste cooking oil is strictly classified and placed at the source of production, and collected in special collection containers. Collection and transportation units use special collection and transportation vehicles and collection containers to transport waste oil. At present, collection and transportation units mostly use large-mouth plastic barrels with lids to collect and transport waste cooking oil, which can meet the requirements of preventing spillage and dripping during transportation. According to the production volume of different catering units, large-mouth waste grease barrels of different specifications are matched, and the commonly used specifications are 25L to 75L. The collection and transportation unit transports the collected barrels of waste cooking oil to the waste cooking oil treatment plant, manually dumps them into the unloading equipment, and then removes impurities, heats, dehydrates and removes residues. However, the following problems still exist when dumping the waste cooking oil in the barrel into the unloading equipment:

[0006] 1. Since the waste cooking oil contains a large amount of animal fat, the waste oil collected by the collection and transportation unit is in a viscous and solid state, which is difficult to dump and clean, that is, there is a problem of difficulty in discharging;

[0007] 2. Waste butter in kitchen waste grease is very easy to solidify into solid and needs to be heated for a period of time before it can be melted, which brings certain difficulties to the collection and treatment work and affects the unloading efficiency;

[0008] 3. Since the waste cooking oil contains a large amount of solid debris, it is very easy to block the unloading equipment and the screen of the back-end equipment during unloading, which also affects the unloading speed;

[0009] 4. During the unloading process of kitchen waste grease, odor escapes and is easily spilled, affecting environmental hygiene;

[0010] 5. The waste grease barrels after dumping should be recycled and cleaned after unloading to avoid spillage during handling, transportation and collection. However, waste grease barrels are adhered to grease, which is difficult to clean and affects the speed of unloading.

[0011] Therefore, it is urgent to propose a new technical solution to solve the problems existing in the prior art. Summary of the invention

It can be seen that the kitchen waste grease unloading equipment provided by the present application can reduce the manual participation in the unloading of grease in the grease barrel, improve the unloading efficiency, improve environmental hygiene, and reduce the difficulty of unloading grease.

[0044] 2. The waste grease collection bin in the present application is a cone-shaped structure, and a waste grease discharge port is provided at the top of the cone. Such a structural design can utilize the principle of gravity to make the grease more easily flow to the bottom discharge port to reduce residue, and the conical design reduces the accumulation of grease in the bin, reduces the adhesion of grease and debris, and reduces the possibility of blockage; the present application also provides an equipment bracket at the bottom of the waste grease collection bin to enhance the stability of the equipment, improve the carrying capacity, and adapt to the grease collection needs of different weights and capacities.

[0045] 3. In the present application, one or more unloading channels are provided, and the unloading channels correspond one-to-one to the conveying and filtering devices. Multiple unloading channels can adapt to grease barrels of different specifications, that is, they can adapt to the unloading needs of various containers, thereby improving the versatility of the equipment.

Multiple unloading channels are processed in parallel, thereby reducing the waiting time and improving the overall work efficiency. Furthermore, multiple unloading channels are efficiently integrated in a limited space, and the overall structure of the equipment is compact, thereby improving the efficiency of space utilization.

[0046] 4. In this application, the unloading platform and the barrel recovery platform at both ends of the unloading channel are arranged adjacent to each other, which can facilitate the operation of personnel.

[0047] 5. In this application, the height of the unloading platform is flush with the height of the trunk of the restaurant waste grease collection and transportation vehicle, or the height of the unloading platform is lower than the height of the trunk of the restaurant waste grease collection and transportation vehicle, which makes it convenient for personnel to carry the grease barrels and facilitate their operations.

[0051] 9. The neutral barrel ramp device of the present application uses the concave arc surface design of the arc plate to make the grease barrel transition more smoothly during the inverted process, reduce stagnation or resistance, and thus improve the overall efficiency of unloading. The present application cleverly realizes the turning design through the arc plate. The grease barrel automatically moves along the arc plate under the push of the subsequent grease barrel. The arc plate also plays the role of guiding and exporting the grease barrel, which realizes effective forward steering of the grease barrel in a limited space, saves the space footprint of the equipment, and enhances the layout flexibility of the equipment. In addition, the grease barrel gradually rises to an inverted state on the concave arc surface, reducing the instability during the dumping process, and this structural design reduces the intervention of operators, making the entire unloading process more automated and convenient, and improving work efficiency.

[0052] 10. In the present application, a climbing section is provided at one end of the guide rail assembly to lift the grease barrel, so that a pouring distance is formed between the barrel mouth of the grease barrel and the upper surface of the conveying and filtering device, which facilitates the pouring of the grease in the barrel.

[0053] 11. The conveying and filtering device in the present application filters and screens the grease poured onto the filter chain plate through the filter chain plate and a plurality of sieve holes arranged on the filter chain plate, thereby achieving continuous conveying and filtration, improving work efficiency, and reducing the need for manual intervention.

[0054] 12. In the present application, the debris conveying device is used to effectively and quickly convey the filtered debris to the outlet, thereby reducing the residence time of the debris in the trough and improving the processing efficiency. The drain holes at the bottom of the trough can effectively discharge the liquid in the debris and the flushed grease into the waste grease collection bin; in the present application, the cleaning roller brush is in contact with the filter chain plate, which can clean the debris on the filter chain plate, ensure the working efficiency of the filter chain plate, and reduce the need for manual cleaning.

[0055] 13. The present application heats the grease barrel after unloading through a steam heating system, which can melt the grease agglomerated in the barrel. The fluidity of the heated grease is enhanced, which can effectively help the grease to be discharged. The heating can shorten the grease processing time and improve the overall processing efficiency. The first barrel position sensor in the present application is connected to the steam control valve signal, which can monitor the position of the grease barrel in real time to ensure heating at the appropriate position, improve the economy of the equipment, and reduce unnecessary energy waste. In addition, the present application uses the lower tubular guide rail in the guide rail assembly as a steam pipe to achieve integrated multi-functions and an exquisite overall structural design.

[0056] 14. The present application also provides a flushing system and / or a blowing system. By providing the flushing system, the residues on the inner wall of the grease barrel can be effectively removed and the accumulation of grease can be reduced. The second barrel position sensor is linked to the flushing water control valve to achieve automatic flushing. When the grease barrel reaches the specified position, the flushing is automatically started to improve the convenience and efficiency of the operation. The present application provides a blowing system to quickly dry the grease barrel, shorten the waiting time, improve the efficiency of the entire processing flow, and ensure the smooth progress of subsequent operations. Timely cleaning and drying can effectively reduce the odor caused by grease residue, improve the working environment, and enhance the work experience of operators. The present application reduces the need for manual operation and improves processing efficiency through automated flushing and blowing systems. BRIEF DESCRIPTION OF THE DRAWINGS

Among them: the small barrel unloading channel 3 is composed of a lower tubular guide rail 301, a middle tubular guide rail 302, and an upper tubular guide rail 303. The spacing of the lower tubular guide rail 301 is smaller than the spacing of the middle and upper guide rails. The lower tubular guide rail 301 can support the upper closing part of the waste grease barrel, and the middle tubular guide rail 302 and the upper tubular guide rail 303 can contact the outer wall of the waste grease barrel to play a guiding and anti-dumping role. Along the direction of the waste grease barrel, in one section, the lower tubular guide rail 301, the middle tubular guide rail 302 and the upper tubular guide rail 303 will show an upward trend. When the waste grease barrel moves along the guide rail, it gradually rises to a certain height to a suspended state, which is convenient for the discharge of the material in the barrel and the subsequent heating, flushing and drying process.

[0076] The form of the large barrel unloading channel 11 is similar to the small barrel unloading channel 3, which is mainly used to adapt to waste grease barrels of different sizes.

The inner surface of the arc-shaped plate facing the inverted barrel device 5 is a concave arc surface. The horizontally inverted grease barrel moves toward the concave arc surface, and the bottom of the grease barrel gradually rises along the concave arc surface under the push of the subsequent grease barrels loaded onto the unloading channel until the grease barrel becomes an inverted state, and the inverted grease barrel turns along the arc plate and continues to move along the guide rail assembly under the push of the subsequent grease barrels loaded onto the unloading channel.

[0081] In a preferred embodiment of the present application, the debris conveying device 7 is arranged at the lower part of the driving sprocket 402 of the conveying and filtering device 4 to collect the waste grease and debris conveyed by the filtering chain plate 404. The debris conveying device 7 has a drain hole at the lower part, and the drain hole size is a waist hole of 20mm*30mm. The waste grease and debris are further drained during the collection and transportation process, reducing the amount of grease carried on the debris.

The use of the kitchen waste grease unloading equipment provided in the present application can reduce the manual participation in unloading the grease in the grease barrel, improve the unloading efficiency, improve the environmental hygiene, and reduce the difficulty of unloading the grease.

[0095] Embodiment 2

[0096] This embodiment provides a method for using a kitchen waste grease unloading device, and the specific method is as follows:

[0097] After the waste grease collection vehicle enters the factory, open the discharge bin door 2 of the discharge equipment, open the control valve of the odor collection port 12, reverse the vehicle so that the tail box is close to the unloading platform 1, move the waste grease barrel on the collection vehicle to the unloading platform 1, and open the upper cover. According to the size of the waste grease barrel, place the waste grease barrel on the small barrel unloading channel 3 or the large barrel unloading channel 11.

[0098] The waste grease barrel is driven by the conveying and filtering device 4 and moves forward along the discharge channel under the guidance of the middle tubular guide rail 302 and the upper tubular guide rail 303. When the waste grease barrel contacts the bucket tipping device 5, it is tipped in the opposite direction of the forward direction under the blocking effect of the bucket tipping device 5, and the waste grease in the barrel will be discharged onto the filter chain plate 404 of the conveying and filtering device 4, and the liquid and small solid particles will enter the waste grease collection bin 14. The tipped waste grease barrel and the large solid particles on the filter chain plate 404 will continue to move forward under the driving effect of the filtering device, and when the tipped waste grease barrel contacts the vertical bucket ramp device 6, it will rise along the ramp of the vertical bucket ramp device 6 until it is in an inverted state. As the waste grease barrels are continuously unloaded, the waste grease barrel at the rear end will push the waste oil barrel at the front end to continue moving forward, the inverted waste grease barrel will move along the lower tubular guide rail 301 and be lifted to a certain height, the inverted waste grease barrel will be separated from the filter chain plate 404, and the debris in the waste grease barrel will be completely unloaded onto the filter chain plate 404 and transported to the debris conveying device 7.

[0099] The cleaning roller brush 8 arranged on the side of the driving sprocket 402 of the conveying and filtering device 4 can clean the solid debris on the filter chain plate 404 into the debris conveying device 7 to prevent it from entering the waste grease collection bin 14. The debris cleaning spray system 9 arranged on the upper part of the debris conveying device 7 will spray water to wash away the grease adhered to the debris collected in the debris conveying device 7, and the flushing water and the grease will enter the waste grease collection bin 14 from the drain hole of the debris conveying device 7.

[0100] The waste grease barrel on the lower tubular guide rail 301 is further pushed forward by the oil barrel at the rear end under the guidance of the middle tubular guide rail 302 and the upper tubular guide rail 303, and enters the steam heating system 17. If there is a problem of solidification and agglomeration in the waste grease barrel entering the factory, the steam valve at the steam interface 1701 is opened to heat the grease in the waste grease barrel. The steam is heated by the steam nozzle 1702 at the lower side of the waste grease barrel to promote the melting of solid grease and clean the waste grease barrel at the same time. The steam nozzle 1702 sprays steam in the upper side direction, and the steam directly melts the solidified agglomerated grease on the edge of the waste grease barrel. In a relatively short time, the diameter of the solidified agglomerated grease block can be reduced and poured onto the filter chain plate 404. In winter, some waste grease barrels are severely solidified and agglomerated, and there may also be a problem of water freezing. The waste grease barrel needs to be heated for a long time to melt and unload. When unloading waste grease, after multiple waste grease barrels are stopped at the position of steam nozzle 1702, the operation of the filtering equipment is stopped, the unloading bin door 2 is closed, the control valve of the odor collection port 12 is closed, and the waste grease in the waste grease barrel is kept for a period of time until the waste grease is completely melted before continuing to operate.

[0101] The waste grease barrel on the lower tubular guide rail 301 is further pushed forward by the oil barrel at the rear end under the guidance of the middle tubular guide rail 302 and the upper tubular guide rail 303, and enters the flushing system 18. If the waste grease barrel needs to be cleaned, the valve at the flushing water interface 1801 is opened, and the flushing nozzle 1802 will spray high-pressure water to flush the waste grease barrel to clean the grease inside and on the surface of the oil barrel. The waste grease barrel is pushed forward by the oil barrel at the rear end to the blowing system 19, and the blowing nozzle 1902 located just below and just above the waste grease barrel blows and dries the inside and outside of the waste grease barrel to quickly remove water droplets inside and outside the waste grease barrel.

[0102] After cleaning and drying, the waste grease barrel will be inverted and come out from the unloading channel of the unloading platform 1. The unloading personnel will screw on the waste grease barrel cover and collect the waste grease barrel on the collection and transportation vehicle. The collection and transportation vehicle will continue to collect the kitchen waste grease after leaving the factory, and repeat this process.

[0103] The waste grease collecting bin 14 buffers part of the waste grease, and a pump conveying system can be installed behind the waste grease discharge port 15 of the waste grease collecting bin 14, and the waste grease collected in the waste grease collecting bin 14 can be conveyed to the back-end processing equipment by the pump.

[0104] A certain amount of debris can be buffered on the debris conveying device 7, and the grease on the debris can be washed off with the cooperation of the upper debris cleaning spray system 9, and the debris can be further drained during transportation. The debris is transported to the rear-end dehydration equipment through the debris outlet 16 for further dehydration and deoiling treatment.

[0105] Therefore, the present application realizes the automatic emptying, dumping, cleaning and drying of the kitchen waste grease barrel, improves the work efficiency of kitchen waste grease unloading, and solves the problem of grease spillage and odor leakage during kitchen waste grease unloading; the unloading equipment can heat and oil the waste grease, solves the problem of waste grease solidification and agglomeration and difficulty in unloading, and improves the unloading speed; the unloading equipment can sort the unloaded waste grease, screen out a large amount of solid debris, and transport them to the back-end equipment after cleaning, thereby improving the recycling rate of the waste grease.

[0106] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0107] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
