Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composting machines, in particular to a kitchen waste composting machine. BACKGROUND

[0002] Kitchen waste refers to garbage generated in daily life, food processing, catering services, and unit meal services, including discarded vegetable leaves, leftovers, fruit peels, eggshells, tea dregs, and bones, etc. Its main sources are household kitchens, restaurants, hotels, canteens, markets, and other food processing-related industries. Kitchen waste is one of the raw materials for ecological fertilizer, so more and more kitchen waste is collected and processed for reasonable use. However, unlike straw, human, livestock, poultry manure, cake meal, agricultural and sideline products, and solid waste generated in food processing, which can be easily collected in large quantities, household kitchen waste is small in unit volume, widely dispersed, and difficult to collect in large quantities, so it is mainly treated by incineration or landfill with other household garbage, which is a waste.

[0003] However, kitchen waste is prone to rot and odor, so many household kitchen waste crushers have appeared on the market. By crushing the kitchen waste to the appropriate particle size and then discharging it into the sewer, the convenience and cleanliness of residents' life are improved. However, the crushed material may hang on the pipe and cause blockage, which is very troublesome.

[0004] Some families now use composting barrels or composting machines to compost kitchen waste for reasonable use, which not only effectively solves the problem of pipe blockage caused by kitchen waste crushers, but also can apply the fertilizer to household potted plants and vegetable and fruit planting. However, the composting barrel has slow composting efficiency and obvious odor, which cannot be used in residential areas. If a composting machine is purchased for combined use with a kitchen waste crusher, not only the cost is high, but also the corresponding space is occupied, which is very troublesome.

[0005] Therefore, the research purpose of the present application is to design a kitchen waste composting machine that can realize kitchen waste crushing, drying, and composting, effectively solve the pipe blockage problem of traditional kitchen waste treatment equipment, directly process kitchen waste into usable fertilizer, and has compact and delicate overall layout and small space occupation.

[0027] Advantages of the present application:

[0028] 1) The present application improves the layout and structure to obtain solid ecological fertilizer directly used by crushing, drying and composting kitchen waste, and the shell is reasonably divided into different parts by the stirring barrel and the air guide channel for exhaust, so that the compact installation of the crushing mechanism, the heating mechanism, the exhaust filtering mechanism, the humidifying mechanism, the cooling mechanism and the sterilization mechanism is facilitated, the equipment volume and the occupied space are significantly reduced, and the use functionality is improved, and the kitchen waste is directly processed into available fertilizer.

[0029] 2) The crushing knife and the stirring barrel of the traditional kitchen waste crusher are fixedly connected, and after being used for a period of time, the stirring barrel is difficult to clean or cannot be cleaned, which causes the kitchen waste stirring barrel to be mildewed and smelly, and further affects the quality of composting. Therefore, the present application provides a quick release mechanism for detachably connecting the stirring barrel and the grinding knife seat, so that the grinding knife can be quickly detached for overall cleaning of the grinding knife based on the stable installation of the grinding knife. The lower part of the mounting hole of the grinding knife seat and the lower outer side of the connecting piece movably mounted in the mounting hole are set as a matching necking, a corresponding through hole is provided at the necking of the connecting piece, a steel ball is movably installed in the through hole, the grinding knife seat and the connecting shaft are installed, the connecting piece is aligned with the connecting shaft and directly pressed downward, the connecting piece moves upward under the pushing of the connecting shaft and compresses the first elastic member, after the grinding knife seat and the connecting shaft are installed in place, the connecting piece rebounds and moves downward to be sleeved on the connecting shaft under the elastic potential of the first elastic member, the steel ball moves axially inward under the guidance of the necking chamfer surface of the mounting hole and is buckled into the embedding groove of the connecting shaft, thereby locking and fixedly connecting the grinding knife seat and the connecting shaft, the installation method is simple and convenient, easy to operate, the connection is stable, the knife is used, and the convenience and practical effect of installation are effectively improved.

[0030] 3) The present application further sets first and second inclined surfaces with opposite inclined directions on the button and the connecting piece, and movably installs a moving piece in the shape of a steel ball between the first and second inclined surfaces of the button and the connecting piece; when disassembling, the moving piece moves axially inward under the guidance of the first inclined surface by pressing the button, the moving piece contacts the second inclined surface of the connecting piece, the connecting piece is pushed upward and moves upward due to force decomposition, and the locking piece in the shape of a steel ball on the connecting piece is moved, the locking piece moves upward, and the locking stroke is released, so that the connecting piece is disconnected from the buckle of the connecting shaft, and then the grinding knife seat is pulled upward at the same time, so that the disassembly is completed conveniently and quickly, and the vertical force N applied to the button needs to ensure that the upward thrust of the connecting piece is greater than the elastic potential of the first elastic member. Therefore, the first elastic member can not only ensure that the connecting piece can move downward to buckle the connecting shaft during installation, but also limit the force during disassembly, effectively protect the quick release mechanism, avoid accidental disconnection, and ensure the stability of the connection.

[0031] 4) The present application is used for conveniently disassembling the grinding blade through the cooperation of the unlocking mechanism and the self-locking mechanism, since the force continuously applied to the button needs to be greater than the vertical force N, and the base seat needs to be pulled synchronously to unlock and disassemble, otherwise the connecting piece will be driven to move downward again to lock and connect under the resetting force of the first elastic member, further ensuring the stability of installation.

[0032] 5) The present application is used for deodorizing and filtering the waste gas through the cooperation of the activated carbon filter core and the exhaust fan, and the exhaust fan is used for guiding the gas, so that the gas is uniformly transmitted and contacted with the cooling mechanism to be cooled, thereby reducing the temperature of the exhaust gas, improving the good experience and use effect of the present application; and the corresponding horizontal guide pipe is vertically arranged at the gas outlet end of the air guide channel, so as to provide a relatively independent space for the sterilization mechanism to work, so that the ozone generated by the ozone generator can fully contact with the waste gas, and the sterilization effect is improved; in addition, the temperature in the horizontal guide pipe is reduced in the process of transmitting the cooled waste gas, so as to provide a suitable temperature environment for the sterilization action of the ozone generator, thereby providing the ozone generator with the temperature environment and space closed restriction required for the sterilization action, so as to ensure the smooth completion of the sterilization action, further improve the sterilization effect. And the last activated carbon filter core is installed behind the ozone generator, which can further improve the filtering effect of the waste gas in the kitchen waste treatment process, and effectively solve the problem of ozone odor caused by the addition of the ozone sterilization mechanism, thereby improving the good experience of the present application.

[0033] 6) The cooling mechanism of the present invention is composed of a semiconductor refrigeration plate and a dispersed heat conducting member that are in contact with each other, and the dispersed heat conducting member is evenly distributed with many long air holes, which cooperate with the long air holes to form a grid shape. In this way, on the basis of ensuring the smooth circulation of exhaust gas, the dispersed heat conducting member can effectively conduct and disperse the temperature of the semiconductor refrigeration plate, ensuring that the exhaust gas can fully contact the dispersed heat conducting member for cooling, thereby improving the cooling effect and efficiency. Furthermore, the longitudinal section of the dispersed heat conducting member is set to a W-shaped structure, so that the water droplets condensed on the dispersed heat conducting member due to the cooling of the exhaust gas can be guided and gathered along its inclined surface, and fall under the action of gravity and gather on the water collecting box below; and through the conduction mechanism formed by the water collecting box, the water pipe and the constant flow valve, it is connected to the water pump to discharge the condensed water in time to ensure the dryness in the equipment and to increase the service life of the equipment; and composting causes the water content of the exhaust gas to increase significantly, and the cooling mechanism is used to condense the gaseous water in the exhaust gas. The liquid water is recycled into the compost through the water pump, thereby effectively achieving the effect of saving water resources. By adding a set flow valve between the water collecting box and the water pump, the water pump can simultaneously pump liquid from the water collecting box and the water storage cylinder when it is started. When there is no water in the water collecting box, the connection between the water collecting box and the water pump is disconnected by controlling the fixed flow valve. Not only can the water in the water collecting box be pumped out in time for use, ensuring a dry use environment, but it can also avoid the problem of turbulence on the flow of exhaust gas when pumping without water, thereby improving the practical effect of the present invention.

[0034] 7) The present invention adds a sterilization mechanism and a cooling mechanism on the basis of the exhaust filter mechanism, and sends the exhaust gas filtered and guided by the exhaust filter mechanism into the cooling mechanism to reduce the temperature of the exhaust gas discharged externally. The sterilization mechanism is then used to kill harmful bacteria in the exhaust gas, thereby effectively preventing bacteria from growing at the exhaust port of the food waste disposer due to high temperature and high humidity.

[0035] 8) The humidifying mechanism of the present application is composed of a water storage cylinder and a water collecting box to form a double water inlet channel, and the detachable water storage cylinder is convenient for personnel to take and add water, and the water storage cylinder and the cover body are respectively provided with corresponding communicating vessels and reverse stop pieces, and after the cover body is connected to the shell by turning down, the communicating vessel is inserted into the reverse stop piece to form communication between the water pump and the water storage cylinder, and then the water pump draws water from the water storage cylinder to promote the completion of composting. Due to the humidification of composting, the water content of the exhaust gas increases, and after the exhaust, the humidity of the space near the exhaust port increases, which not only affects the environment of the equipment and affects the service life, but also causes the air humidity in the area to be high and easy to mold. Through the added cooling mechanism, the gaseous water in the exhaust gas can be condensed into liquid water, thereby controlling the humidity and water content of the exhaust gas, improving the practical effect of the present application. The water collecting box is arranged below the cooling mechanism, the W-shaped arrangement of the non-standard part dispersion temperature guide piece promotes the condensate water to flow and gather into the water collecting box, and then the water collecting box is reused for composting humidification through the cooperation of the conduction mechanism and the water pump. Not only effectively realizes the recycling of water and saves water resources, but also prevents the condensate water from gathering to reduce the service life of the equipment, and prevents the area where the composting machine is located from being prone to mold due to high water content and temperature of the exhaust gas, further improving the practical effect of the present application.
