Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a backwashing kitchen waste disposer. Background Art

[0002] Kitchen waste refers to the garbage generated in residents' daily lives and food processing, catering services, unit meal supply and other activities, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, eggshells, tea dregs, bones (chicken bones, fish bones), etc. Its main sources are home kitchens, restaurants, hotels, canteens, markets and other industries related to food processing. Kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce foul odors. After solid-liquid separation and proper treatment and processing, it can be converted into new resources. The high organic matter content in its solids allows it to be used as fertilizer and feed after strict treatment. It can also produce biogas for fuel or power generation, while the liquid oil and fat part can be used to prepare biofuels.

[0003] At present, in the process of solid-liquid separation of kitchen waste, due to the large amount of oil contained in the separated liquid and small solid particles of impurities will accumulate on the surface and mesh of the filter, causing the filter to be blocked, affecting the solid-liquid separation of kitchen waste. For this reason, we propose a backwash kitchen waste disposer. Utility Model Content

[0004] The purpose of the present utility model is to provide a backwash kitchen waste disposer, which has the advantage of being able to backwash the filter during the solid-liquid separation process of kitchen waste, thereby avoiding clogging of the filter due to grease and solid particles, and ensuring the efficiency of kitchen waste treatment. It solves the problem that in the current process of solid-liquid separation of kitchen waste, the separation liquid contains a lot of grease and small solid particles of impurities will accumulate on the surface and mesh of the filter, causing clogging of the filter and affecting the solid-liquid separation of kitchen waste.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a backwash kitchen waste disposer, comprising a grinder, a separation drum and a liquid collecting box, wherein the grinder is fixedly mounted on one side of the upper surface of the separation drum, an extrusion screw is rotatably mounted inside the separation drum, a rotating motor is fixedly mounted on the outer surface of the separation drum close to the grinder, a liquid outlet is provided on the lower surface of the separation drum, a filter is fixedly mounted inside the liquid outlet, a liquid collecting box is fixedly mounted on the lower surface of the separation drum, a detergent box is fixedly mounted on the upper surface of the separation drum, a flushing pump is fixedly mounted on the rear surface of the liquid collecting box, a branch pipe is fixedly connected to the end of the flushing pump output pipe, and the branch pipe is located inside the liquid collecting box, and a plurality of nozzles are fixedly mounted at equal intervals on the upper surface of the branch pipe.

[0006] Preferably, the end of the output shaft of the rotating motor and the end of the extrusion screw are fixedly connected.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, the utility model proposes a backwash kitchen waste disposer, including a grinder 2, a separation drum 4 and a liquid collecting box 8. The grinder 2 is fixedly installed on one side of the upper surface of the separation drum 4. The kitchen waste is crushed by the grinder 2 and falls into the separation drum 4. An extrusion screw 9 is rotatably installed inside the separation drum 4. A rotating motor 1 is fixedly installed on the side of the outer surface of the separation drum 4 close to the grinder 2. The end of the output shaft of the rotating motor 1 and the end of the extrusion screw 9 are fixedly connected. The rotating motor 1 drives the extrusion screw 9 to rotate and squeezes the crushed kitchen waste, thereby completing the solid-liquid separation treatment of the kitchen waste. A necking pipe 5 is welded on the side of the outer surface of the separation drum 4 facing away from the rotating motor 1, and a slag discharge valve 6 is fixedly connected to the end of the necking pipe 5.

[0024] The lower surface of the separation cylinder 4 is provided with a liquid outlet 12, and a filter screen 13 is fixedly installed inside the liquid outlet 12. The filter screen 13 is used for solid-liquid separation of kitchen waste. A liquid collecting box 8 is fixedly installed on the lower surface of the separation cylinder 4. The upper part of the liquid collecting box 8 is open, and the outer surface of the liquid collecting box 8 is fixedly connected to a drain valve 7 on the side away from the rotating motor 1. The liquid separated from the kitchen waste passes through the filter screen 13 and falls into the liquid collecting box 8. A cleaning agent box 3 is fixedly installed on the upper surface of the separation cylinder 4. Grease cleaning agent is stored in the cleaning agent box 3. A flushing pump 17 is fixedly installed on the rear surface of the liquid collecting box 8. The end of the flushing pump 17 input pipe is fixedly connected to the rear surface of the cleaning agent box 3 near the lower surface. The upper surface of the cleaning agent box 3 is fixedly connected with a liquid replenishing valve 15, and the cleaning agent is replenished to the inside of the cleaning agent box 3 through the liquid replenishing valve 15. The end of the flushing pump 17 output pipe is fixedly connected to a branch pipe 10, and the branch pipe 10 is located inside the liquid collecting box 8. Several nozzles 11 are fixedly installed at equal intervals on the upper surface of the branch pipe 10.

[0025] When the present invention is in use, kitchen waste is put into the grinder 2 and crushed. The crushed kitchen waste enters the separation drum 4, and the extrusion screw 9 squeezes the kitchen waste. The squeezed liquid passes through the filter 13 and enters the liquid collecting box 8, and the solid is discharged from the slag discharge valve 6, thereby completing the solid-liquid separation treatment of the kitchen waste. In the long-term treatment process, the grease and solid-liquid particles in the separated liquid will accumulate on the surface and mesh of the filter 13, causing the filter 13 to be blocked. At this time, the flushing pump 17 is working, and the cleaning agent inside the cleaning agent box 3 is sprayed back to the filter 13 through the nozzle 11, and the filter 13 is reversely flushed to clean the grease and solid particles on the filter 13, thereby avoiding clogging of the filter 13 and ensuring the efficiency and effect of the solid-liquid separation treatment of the kitchen waste.

[0026] Example 2

[0027] like Figures 3 and 4 As shown, the utility model proposes a backwash kitchen waste disposer. Compared with the first embodiment, this embodiment also includes a heating plate 16 fixedly installed near the lower surface of the detergent box 3. The heating plate 16 heats the detergent inside the detergent box 3. During the backwashing of the filter 13, the grease on the filter 13 can be better melted and removed by the detergent. An electric push rod 14 is fixedly installed on the side of the outer surface of the liquid collecting box 8 near the rotating motor 1, and the end of the electric push rod 14 is fixedly connected to the outer surface of the branch pipe 10.

[0028] In this embodiment, the electric push rod 14 drives the branch pipe 10 to move back and forth, so that the cleaning agent sprayed by the nozzle 11 is sprayed evenly toward the filter 13, thereby improving the backwashing effect of the filter 13.

[0029] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
