Description

Technical Field

[0001] This utility model relates to the field of waste treatment, and in particular to a dehydration device for treating kitchen waste. Background Technology

[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and unit catering activities. It includes discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets, and other food processing-related industries. Kitchen waste contains extremely high moisture and organic matter, which makes it easy to decompose and produce a foul odor. Dehydration is required during the treatment of kitchen waste.

[0003] For example, patent document CN223165886U discloses a dewatering device for treating kitchen waste. The device uses the rotation of a screw rod to squeeze and dewater the waste inside the container. The wastewater flows through a filter plate at the bottom of the container into a guide box for collection. The dewatered waste is pushed by the screw rod to the discharge box and then discharged. A spray pipe is installed at the top of the container to rinse the inside of the container.

[0004] However, the filter plate at the bottom of the chamber is prone to clogging. The spray pipe is located at the top, and the sprayed water falls directly onto the screw rod, making it impossible to directly rinse the filter plate at the bottom. Therefore, the cleaning effect on the filter plate is generally poor, and it is difficult to unclog some severely clogged areas, resulting in mediocre performance. Utility Model Content

[0005] The purpose of this invention is to provide a dehydration device for treating kitchen waste in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A dewatering device for treating kitchen waste includes a wastewater tank with a dewatering mechanism. The dewatering mechanism includes a dewatering cylinder fixedly connected to the top of the wastewater tank, with filter holes at the bottom of the dewatering cylinder. A cleaning mechanism is provided on the dewatering cylinder, comprising two rings rotatably connected to the dewatering cylinder. Two flushing pipes are fixedly connected between the two rings, and a cleaning shaft is provided between the two flushing pipes. The cleaning shaft is rotatably connected to the rings and has steel bristles. A planetary gear is fixedly connected to one end of the cleaning shaft, meshing with a fixed gear ring, which is fixedly connected to one end of the dewatering cylinder. A first power mechanism and a second power mechanism are provided on the wastewater tank. The first power mechanism provides power to the dewatering mechanism, and the second power mechanism drives the rings to rotate.

[0008] Preferably, the wastewater tank is fixedly connected to the front and rear sides of the support frame, the dewatering cylinder is fixedly connected to the support frame, and the wastewater tank is fixedly connected to the front side of the drain pipe.

[0009] Preferably, the dewatering mechanism further includes a feed hopper fixedly connected to the top of the dewatering cylinder, a discharge pipe fixedly connected to the end of the dewatering cylinder away from the feed hopper, and a spiral extrusion shaft rotatably connected inside the dewatering cylinder.

[0010] Preferably, the first power mechanism includes a first motor, which is fixedly connected to the side wall of the wastewater tank. The output shaft of the first motor is fixedly connected to a drive sprocket, a chain is connected to the drive sprocket, and a driven sprocket is connected to the other end of the chain. The driven sprocket is fixedly connected to the spiral extrusion shaft.

[0011] Preferably, a first nozzle and a second nozzle are fixedly connected to the rinsing pipe, with the water outlet direction of the first nozzle facing the filter hole and the water outlet direction of the second nozzle facing the cleaning shaft.

[0012] Preferably, the second power mechanism includes a second motor, which is fixedly connected to the side wall of the wastewater tank. The output shaft of the second motor is fixedly connected to a drive gear, which meshes with a driven gear ring, which is fixedly connected to the ring body.

[0013] The beneficial effects are as follows: when the ring rotates, it drives the flushing pipe and the cleaning shaft to make circular motion. The flushing pipe sprays high-pressure water to flush the filter holes at the bottom of the dewatering cylinder. When the cleaning shaft makes circular motion, the planetary gear revolves around the fixed gear ring. Therefore, the planetary gear will also rotate and drive the cleaning shaft to rotate. The steel bristles on the cleaning shaft are used to clean the filter holes, resulting in a good cleaning effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6As shown, a dewatering device for treating kitchen waste includes a wastewater tank 1 and a dewatering mechanism 2. The dewatering mechanism 2 includes a dewatering cylinder 201 fixedly connected to the top of the wastewater tank 1. The bottom of the dewatering cylinder 201 has a filter hole 202. The dewatering mechanism 2 also includes a feeding hopper 203 fixedly connected to the top of the dewatering cylinder 201. The end of the dewatering cylinder 201 away from the feeding hopper 203 is fixedly connected to a discharge pipe 204. A screw extrusion shaft 205 is rotatably connected inside the dewatering cylinder 201. By rotating the screw extrusion shaft 205, the kitchen waste in the dewatering cylinder 201 is extruded and dewatered, and the discharge pipe 204 is pushed. The wastewater flows into the wastewater tank 1 through the filter hole 202. Supports 101 are fixedly connected to the front and rear sides of the wastewater tank 1. The dewatering cylinder 201 is fixedly connected to the supports 101. A drain pipe 102 is fixedly connected to the front side of the wastewater tank 1 for discharging the dewatered wastewater.

[0027] A cleaning mechanism 3 is provided on the dehydration cylinder 201. The cleaning mechanism 3 includes two rings 301, which are rotatably connected to the dehydration cylinder 201. Two rinsing pipes 302 are fixedly connected between the two rings 301. The rinsing pipes 302 are connected to a high-pressure water source via hoses (not shown in the figure). A cleaning shaft 303 is provided between the two rinsing pipes 302 and is rotatably connected to the rings 301. The cleaning shaft 303 is provided with steel bristles. A planetary gear 304 is fixedly connected to one end of the cleaning shaft 303. The planetary gear 304 meshes with a fixed gear ring 305, which is fixedly connected to one end of the dehydration cylinder 201. When the rings 301 rotate, they drive the rinsing pipes 302 and the cleaning shaft 303 to perform circular motion, and the rinsing pipes 302 spray high-pressure water. Water rinses the filter holes 202 at the bottom of the dewatering cylinder 201. When the cleaning shaft 303 makes a circular motion, the planetary gear 304 revolves around the fixed gear ring 305. Therefore, the planetary gear 304 also rotates and drives the cleaning shaft 303 to rotate. The steel bristles on the cleaning shaft 303 are used to clean the filter holes 202, resulting in a good cleaning effect. The rinsing pipe 302 is fixedly connected to a first nozzle 3021 and a second nozzle 3022. The water outlet direction of the first nozzle 3021 is towards the filter holes 202, and the water outlet direction of the second nozzle 3022 is towards the cleaning shaft 303. The first nozzle 3021 is used to rinse the filter holes 202, and the second nozzle 3022 is used to rinse the cleaning shaft 303. This can prevent the cleaning shaft 303 from being too dirty and affecting the cleaning effect.

[0028] The wastewater tank 1 is equipped with a first power mechanism 4 and a second power mechanism 5. The first power mechanism 4 is used to provide power to the dewatering mechanism 2, and the second power mechanism 5 is used to drive the ring 301 to rotate.

[0029] The first power mechanism 4 includes a first motor 401, which is fixedly connected to the side wall of the rear side of the wastewater tank 1 via a motor base. The output shaft of the first motor 401 is fixedly connected to a drive sprocket 402, and a chain 403 is connected to the drive sprocket 402. The other end of the chain 403 is connected to a driven sprocket 404, which is fixedly connected to the spiral extrusion shaft 205.

[0030] The second power mechanism 5 includes a second motor 501, which is fixedly connected to the side wall of the front side of the wastewater tank 1 via a motor mount. The output shaft of the second motor 501 is fixedly connected to a drive gear 502, which meshes with a driven gear ring 503, which is fixedly connected to the ring body 301.

[0031] Working principle: During use, kitchen waste is poured into the dewatering cylinder 201 from the feed hopper 203. The first motor 401 drives the screw extrusion shaft 205 to rotate through the drive sprocket 402, chain 403, and driven sprocket 404. The screw extrusion shaft 205 extrudes and dewaters the kitchen waste and pushes it towards the discharge pipe 204. Wastewater flows through the filter holes 202 into the drain pipe 102 and is finally discharged through the drain pipe 102. The dewatered waste is discharged through the discharge pipe 204. When the filter holes 202 need to be cleaned, high-pressure water from an external source is sent into the rinsing pipe 302 through a hose. The first nozzle 3021 sprays water onto the filter holes 202 for rinsing, and the second nozzle 3022 sprays water onto the cleaning shaft 303 to rinse it. At the same time, the second motor 501 drives the drive gear 502. The drive gear 502 rotates, driving the driven gear ring 503 to rotate. The driven gear ring 503 drives the ring body 301 to rotate, and the ring body 301 drives the flushing pipe 302 and the cleaning shaft 303 to perform circular motion. At this time, the planetary gear 304 moves around the fixed gear ring 305, causing the planetary gear 304 to drive the cleaning shaft 303 to rotate. The steel bristles on the cleaning shaft 303 clean the filter holes 202. The steel bristles can enter the filter holes 202 and play a role in unblocking. Through the reciprocating forward and reverse rotation of the second motor 501, the flushing pipe 302 and the cleaning shaft 303 reciprocate in circular motion, thereby thoroughly cleaning the filter holes 202. After cleaning, the flushing pipe 302 and the cleaning shaft 303 are moved to a position higher than the filter holes 202, thereby preventing a large amount of wastewater from flowing onto the flushing pipe 302 and the cleaning shaft 303 during the dehydration process.

[0032] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
