[0002] In the pretreatment process of kitchen waste, the removal of inorganic impurities, especially fine sand and gravel, is a key link affecting the stable operation of subsequent processing equipment. However, due to process design defects or cost control reasons in some traditional processing systems, professional cyclone sand removal equipment is not configured, resulting in problems during system operation. The remaining fine sand and gravel will enter the subsequent processing unit along with the kitchen waste slurry. In the reactor, it not only occupies the effective volume but also causes pipeline blockage.

[0003] After retrieval, the existing patent (publication number: 202010595097.0) discloses a device for making solid fuel from kitchen waste with cyclone flash evaporation and self-heating cascade utilization, including a heating and extrusion treatment part, a combustion chamber part, a high-speed crushing and cyclone flash evaporation part, a condensation and tail gas treatment part, and a gas-solid separation and solid fuel collection part. The kitchen waste is put into a screw propeller through a feed port, is subjected to variable pitch extrusion and heating from below, and then is pushed into a crushing device by a hand rocker, is crushed by high-speed rotating blades, and small enough materials enter a cyclone drying chamber tangentially along with the flue gas to achieve drying and gas-solid separation. The solid product can be used as fuel to supply drying heat, negative pressure low-temperature flash evaporation is realized inside the device, and the tail gas is discharged after condensation and adsorption. Although this patented technology can achieve self-heating and rapid drying on-site, design a downward ignition combustion chamber to realize the cascade utilization of flue gas heat, with low energy consumption, and at the same time, low-temperature combustion reduces the generation amount of pollutants, and configure a tail gas treatment system to achieve up-to-standard discharge and no secondary pollution, there is a problem that the corrosive kitchen waste becomes more corrosive after fermentation, which will gradually damage the inner wall of the device, resulting in a significant reduction in the service life of the device.

[0023] In the present embodiment, a cyclone sand removal device for kitchen waste is provided. It should be noted that the arrangement of the scraper plate 25, the pull handle 29 and the separator 3 makes it easier and quicker to clean the inside of the pipeline, and the scraping force is stronger, so that the residual oil mixed in the kitchen waste after the sand and gravel are separated can be separated again. Through the coordinated arrangement of the dial 37 and the gear 38, as well as the separator 3 and the slag extraction pipe 4, during use, each time one of the pull handles 29 is pulled, the dial 37 can be toggled by the tooth angle 32, so that the scraper plate 25 scrapes the inner wall of the slurry storage tank 2, so that the slurry storage tank 2 When the inner wall is transferring the food waste, the garbage adhering to the inner wall of the slurry storage tank 2 can be scraped off to avoid clogging in the device and corrosion of the inner wall of the device by the garbage to reduce the service life of the device, and the food waste after the sand and gravel are separated can be processed again to separate the remaining oil in the garbage again, thereby achieving a stronger squeezing force on the food waste and maximizing the extraction of vegetable oil, and the inner wall of the device is scraped to prevent the food waste from being adsorbed on the inner wall of the device for fermentation and thus corroding the inner wall of the device, thereby achieving the purpose of easier cleaning, good cleaning effect, and more thorough separation of oil from food waste.

[0024] Working principle: after separating the sand and gravel from the kitchen waste, the separator 3 is opened, so that the slag extraction pipe 4 on the top of the separator 3 extracts the kitchen waste in the middle of the throwing barrel 23, so that the waste is extracted into the separator 3, and then the remaining residual moisture, vegetable oil and waste residue in the waste are separated as the separator 3 runs. Then, the worker holds one of the pull handles 29, pulls the pull handle 29 downward for several times and then releases it. At this time, as one of the pull handles 29 is pulled several times, one of the tooth angles 32 moves downward during the process of pulling the pull handle 29, thereby turning the dial 37 to rotate a fan blade distance, and then the tooth angle 32 leaves the fan blade position of the dial 37 and is moved once by the side table 30. The bent spring sheet 31 bounces back to its original position, and during the rotation of the dial 37, the smooth curved surface between the fan blades will push the round cone 35 to move downward, thereby compressing the second spring rod 34, so that the dial 37 is no longer rotated and is stuck by the round cone 35 for limiting. At this time, the vertical rod 26 and the scraper plate 25 at the bottom of the rack 27 scrape the inner wall of the slurry storage tank 2, so that the internal garbage residue is scraped into the throwing barrel 23, so that the kitchen waste residue can be cleaned and reprocessed, and the other handle 29 is pulled multiple times to make the scraper plate 25 rise and return to its original position, so as to avoid garbage clogging the pipeline, and placing corrosive garbage on the inner wall of the device for fermentation to erode the inner wall of the device, causing odor in the device and reducing the service life of the device.
