Description
Technical Field
[0001] The present application relates to the technical field of food waste treatment, and in particular to a food waste slurry reflow device. Background Art
[0002] Kitchen waste is mainly domestic waste generated by residents in the process of daily consumption. It is the most important type of food waste, including food processing scraps and edible residues generated by households, schools, canteens and catering industries. Its composition is complex, mainly a mixture of oil, water, fruit peels, vegetables, rice, flour, fish, meat, bones, as well as waste tableware, plastic, paper towels and other substances.
[0003] The field of food waste treatment technology has always been an important link in environmental protection and resource recycling, especially in the management of urban solid waste. It occupies a pivotal position. The effective treatment of food waste can not only reduce environmental pollution, but also realize the recycling of resources and improve the recovery rate of waste, which is of great significance for sustainable development. In the existing technology, food waste is dumped into a sorting machine for sorting, and the non-reusable food waste is picked out. Then, the reusable food waste is crushed by a crusher and then transported to a grit machine to remove the upper suspended matter in the food waste. However, in the process of transporting the material from the crusher to the grit machine through a spiral conveying auger, the grease in the food waste will be transported to the grit machine by the spiral conveying auger and then removed into the waste material by the grit machine. However, grease is one of the more important recyclables in food waste. Therefore, it is urgently needed to design a device that can reduce grease loss while transporting food waste. Utility Model Content
[0004] In order to achieve grease reflow while transporting food waste, the present application provides a food waste slurry reflow device.
[0005] The kitchen waste slurry reflow device provided in this application adopts the following technical solution:
[0006] A kitchen waste slurry reflow device, comprising
[0007] Support frame;
[0008] A conveying box with an opening at one end is obliquely connected to the support frame, and a spiral conveying auger is rotatably connected in the conveying box;
[0009] At least one degreasing nozzle, the water outlet end of the degreasing nozzle extends into the inner cavity of the conveying box, and the degreasing nozzle is arranged toward the spiral conveying auger;
[0010] A water supply unit is used to supply water to the degreasing nozzle, wherein the water supply unit is connected to the delivery box and the water supply unit is connected to the degreasing nozzle.
[0011] By adopting the above technical solution, an external power supply provides power to the spiral conveyor auger. As the spiral conveyor auger rotates, it conveys the food waste through one end of the crusher to the other end of the grit settling machine. Because some grease adheres to the food waste when the spiral conveyor auger rotates and is wasted in the grit settling machine, water is supplied to the degreasing nozzle through the water supply unit while the spiral conveyor auger rotates. The water flows toward the spiral conveyor auger and brushes off the grease adhering to the spiral conveyor auger, allowing the grease to flow back into the bottom area of the conveyor box. The designed food waste slurry return device uses a support frame to facilitate supporting the conveyor box and maintaining its tilt. The spiral conveyor auger can convey food waste. The water sprayed from the degreasing nozzle impacts the grease on the spiral conveyor auger, causing it to break away from the spiral conveyor auger and flow into the bottom area of the conveyor box, thereby effectively reducing grease loss and improving grease recovery rate. The water supply unit facilitates water supply to the degreasing nozzle.
[0012] In a specific possible implementation scheme, an overflow trough is provided on the conveying box, and the overflow trough is located on the top wall of the conveying box.
[0013] By adopting this technical solution, the overflow trough on the conveyor box allows the grease to float on the top layer of the slurry and overflow during the conveying process, effectively reducing the loss caused by grease entering the grit settling machine and improving the grease recovery rate. At the same time, the overflow trough design on the top wall allows the grease to flow out smoothly, avoiding blockage.
[0014] In a specific possible implementation manner, a accommodating box is connected to the conveying box, the inner cavity of the accommodating box is communicated with the inner cavity of the conveying box through the overflow groove, and the top wall of the accommodating box is provided with an opening.
[0015] By adopting the above technical solution, the conveyor box is connected to the storage box, and the inner cavity of the storage box is connected to the inner cavity of the conveyor box through the overflow groove. The top wall of the storage box is also provided with an opening. This design allows the grease and water generated during the conveying process to flow into the storage box through the overflow groove, preventing the direct removal of useful substances such as grease, while keeping the interior of the conveyor box clean and improving the grease recovery rate.
[0016] In a specific embodiment, a filter screen is connected to the conveying box, and the filter screen is located in the overflow trough for filtering the material flowing out of the overflow trough.
[0017] By adopting the above technical solution, a filter is connected to the conveying box, and the filter is located in the overflow trough, which is used to filter the material flowing out of the overflow trough, thereby effectively preventing debris from entering the containing box and ensuring the smooth progress of the processing process.
[0018] In a specific embodiment, the water supply unit includes
[0019] A hollow water storage tank located on one side of the delivery box;
[0020] a water supply pump, the water supply pump being connected to the water storage tank, and the water pumping end of the water supply pump extending into the water storage tank;
[0021] A water pipe, one end of which is connected to the water outlet of the water supply pump, and the water pipe is connected to the delivery box, and the water pipe is connected to the degreasing nozzle.
[0022] By adopting the above technical solution, the hollow water tank can store sufficient water. The water supply pump draws the water out of the water tank and transports it to the degreasing nozzle through the water pipe. The water supply pump ensures a stable supply of water flow, and the water pipe ensures the smooth transmission of water from the water tank to the degreasing nozzle, thereby effectively removing grease from kitchen waste.
[0023] In a specific possible implementation scheme, a heating cylinder is provided on the water pipe, and a plurality of electric heating wires are provided in the heating cylinder, and the plurality of electric heating wires form a heating cavity for the water pipe to pass through.
[0024] By adopting the above technical solution, the heating cylinder is installed on the water pipe, and the heating chamber formed by multiple electric heating wires arranged in the heating cylinder heats the water in the water pipe, thereby ensuring that the water sprayed by the degreasing nozzle can effectively remove the grease on the spiral conveying auger, thereby improving the grease recovery efficiency.
[0025] In a specific embodiment, the water pipe is covered with a thermal insulation layer, and the thermal insulation layer is located between the heating cylinder and the degreasing nozzle.
[0026] By adopting the above technical solution, the thermal insulation layer is coated on the water pipe and between the heating tube and the degreasing nozzle, which can effectively reduce the heat loss of hot water in the water pipe during the transportation process, thereby ensuring that the water temperature sprayed from the degreasing nozzle is appropriate and improving the grease removal effect.
[0027] In a specific possible implementation manner, the water storage tank is connected to the support frame, and the water storage tank is located below the delivery box.
[0028] By adopting the above technical solution, the water tank is connected to the support frame, and the water tank is located below the conveying box, which makes the entire equipment structure more compact and reasonable, easy to install and maintain, while reducing the footprint and improving the space utilization of the equipment. At the same time, the water tank can also serve as a counterweight structure to improve the position stability of the support frame.

The container's interior is connected to the delivery box via an overflow trough, and an opening is provided in the top wall of the container. This design allows grease and moisture generated during the delivery process to flow into the container through the overflow trough, preventing the direct removal of useful substances such as grease, while keeping the interior of the delivery box clean and improving grease recovery.
[0032] 3. The kitchen waste slurry return equipment is designed with a heating cylinder sleeved on the water pipe. The heating chamber formed by multiple electric heating wires arranged in the heating cylinder heats the water in the water pipe, thereby ensuring that the water sprayed by the degreasing nozzle can effectively remove the grease on the spiral conveying auger, thereby improving the grease recovery efficiency.
