Description

Technical Field

[0001] The present invention belongs to the technical field of garbage disposal equipment, and in particular relates to an intelligent kitchen waste disposer. Background Art

[0002] Kitchen waste refers to garbage generated in residents' daily lives and in food processing, catering services, unit meal supply and other activities, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, egg shells, tea dregs, bones, etc. Its main sources are home kitchens, restaurants, hotels, canteens, markets and other industries related to food processing.

[0003] Kitchen waste is a type of organic waste, which is divided into cooked kitchen waste and raw kitchen waste. Cooked kitchen waste includes leftovers, leftover rice, and vegetable leaves. Raw kitchen waste includes fruit peels, eggshells, tea dregs, bones, scallops, etc. my country produces a large amount of kitchen waste every year, and its treatment is a labor-intensive and resource-intensive project. Common treatment methods include incineration and landfill. If kitchen waste is directly incinerated, because it contains a large amount of water, it will not only reduce the temperature of the incinerator, but also reduce the service life of the equipment. If kitchen waste is directly buried, because it contains organic matter, it is easy to rot and stink, and breed mosquitoes, flies, insects, cockroaches and other vectors, which not only hinders public health, but also pollutes air and water sources.

[0004] The main characteristics of restaurant kitchen waste are high water content and a large amount of plant fiber. It is difficult to crush it efficiently using a general crusher with a screen, mainly because the plant fiber with a high water content is tough and soft. During the crushing process, it is difficult for all the fibers to be broken into a slurry and flow out of the screen smoothly. A considerable part of the fiber that cannot be broken and pass through the screen will form fiber slag that blocks the screen in the crushing chamber of the crushing equipment, which not only affects the smooth outflow of the slurry during crushing, but also as the fiber slag accumulates in the crushing chamber, the load of the crushing equipment also increases. If the fiber slag blocked in the crushing chamber cannot be discharged in time, the crushing equipment will trip and shut down due to overload or even burn out the drive device, and production operations cannot proceed normally.

[0005] Previously, in order to solve the problem of crushing and pulping of restaurant kitchen / kitchen waste, an enterprise in the industry designed and developed a restaurant kitchen / kitchen waste biomass separator. The main mechanism and working principle are that a spiral blade shaft is installed in a vertical mesh crushing cylinder cavity. When the restaurant kitchen / kitchen waste is transported into the crushing cylinder cavity during operation, the restaurant kitchen / kitchen waste with less fiber and easy to cut and crush is cut into pulp by the rotary cutter on the high-speed spiral blade shaft and flows out of the crushing cylinder cavity through the mesh on the cylinder cavity. However, after working for a certain period of time, the fiber residue will seriously block the crushing cylinder cavity and the equipment will be overloaded. In order to improve efficiency and avoid burning of the drive device, the crushing cylinder cavity can only be shut down and opened, and the fiber residue in it can be manually cleaned out before the feeding operation can be continued. Therefore, the crushing and pulping of restaurant kitchen / kitchen waste can only be intermittent operation, and the production efficiency is not high enough, which is difficult to meet the needs of large-scale, batch environmental protection treatment and resource utilization of restaurant kitchen / kitchen waste.

[0006] At present, the kitchen waste treatment device on the market crushes the waste through a small crushing mechanism and washes the crushed kitchen waste away through a pool. This device does not separate the solid and liquid of the kitchen waste, resulting in the inability to effectively recycle the kitchen waste, causing a waste of resources.

[0019] Furthermore, in a preferred embodiment of an intelligent kitchen waste disposer of the present invention, a solid-liquid separation chamber is provided between the crushing chamber and the feed port, a guide plate is provided between the solid-liquid separation chamber and the crushing chamber, a liquid treatment box is provided on the lower left side of the solid-liquid separation chamber, the solid-liquid separation chamber and the liquid treatment box are connected by a water pipe, a solid treatment box is provided on the right side of the liquid treatment box, and the solid treatment box is connected to the crushing chamber through the conveying device.

[0020] Furthermore, in a preferred embodiment of an intelligent food waste disposer of the present invention, the steam jacket 5 includes a steam pipeline, a steam compressor and a heating device for providing heat energy to the dryer, one end of the steam pipeline is connected to the steam outlet, and the other end is connected to the steam inlet, and the steam compressor is arranged on the steam pipeline.

[0021] Furthermore, in a preferred embodiment of an intelligent food waste disposer of the present invention, the steam system also includes a flow regulating valve, and the flow regulating valve is arranged on the pipeline between the heating device and the steam pipeline.

[0022] The steam compressor is a variable frequency steam compressor, which enables accurate control of the evaporation temperature, avoids slow evaporation due to too low evaporation temperature, or energy waste due to too high evaporation temperature, and further reduces the energy consumption of drying food and kitchen waste.

[0023] The heating device is a steam generator, and its steam outlet is connected to the pipeline between the steam compressor and the steam inlet. It is understandable that the heating device can be selected from a variety of methods such as electric heaters and microwave heating, and does not need to be equipped with a steam boiler system. It only needs to be able to provide a heating source for the drying tank. However, the steam heating method can be shared with the steam generated by the drying process, which has a better drying effect. Specifically, the steam system also includes a flow regulating valve, which is arranged on the pipeline between the heating device and the steam pipeline.

[0024] The food waste and / or kitchen waste are poured into the feed port, and the crushing device is operated to crush the food waste and / or kitchen waste to reduce the particle size of the food waste and / or kitchen waste.

[0025] The steam compressor is operated to evacuate the dryer 3 to a vacuum state, and the operating pressure of the dryer is controlled below the atmospheric pressure, and the evaporation temperature is controlled to be less than 100°C.

[0026] The heating device is started to provide a heat source for the dryer 3, and the heating device is turned off after reaching a predetermined heat.

[0027] After heating, the food and kitchen waste are separated into steam and dry materials. At this time, the steam compressor is kept turned on, and the steam flows back to the steam inlet through the steam compressor, and the steam heat is reused, which greatly reduces the heat supplement under normal operation of the device, and saves 60% of energy consumption compared with conventional thermal drying technology. During the drying process, the heating device can also be intermittently started to supplement the heat loss of the dryer 3 according to specific needs.

[0028] The condensate generated during the drying process is discharged from the condensate outlet.

[0029] The dried food and kitchen waste materials are discharged from the discharge port, and the moisture content of the dry materials is 20%-30%.

[0030] The dry materials are briquetting by the briquetting machine for subsequent resource utilization.

[0031] Furthermore, in a preferred embodiment of an intelligent food waste disposer of the present invention, the crushing device 2 includes a pair of counter-rotating crushing blade shafts 21 arranged in the crushing chamber along the up-down direction and penetrating the top surface of the crushing chamber, crushing blades 22 arranged on the outer periphery of the crushing shaft 21 and spirally distributed along the up-down direction, and a driving device 23 for driving the crushing blade shaft 21 to rotate, and the gap between the crushing blades 22 and the crushing chamber gradually decreases in the direction from the feed port to the discharge port.

[0032] The kitchen waste slowly passes through the gap between the crushing chamber and the crushing blade 22, and is gradually crushed. Since the gap between the crushing blade 22 and the crushing chamber gradually decreases from the feed port to the discharge port, the crushing force gradually increases from top to bottom, and the kitchen waste is crushed into larger particles at the beginning and then into smaller particles at the end, and the crushing effect is good. The kitchen waste can move smoothly to the discharge port under its own gravity and the pushing action of the crushing blade 22, and no blockage will occur.

[0033] Preferably, the driving device includes a turbine mounted on the outer periphery of the crushing shaft 21, a driving unit arranged on one side of the crushing shaft 21, a worm arranged on the output shaft of the driving unit and meshing with the turbine, and a waterproof cover mounted on the outer side of the turbine, the driving unit and the worm and detachably connected to the crushing shell.

[0034] Specifically, the driving unit includes a driving device and a reducer connected to the output shaft of the driving device, and the worm is connected to the output shaft of the reducer. The transmission structure of the worm gear occupies a small space, has a stable and reliable transmission effect, and can ensure the reliability of the operation of the crushing device 2.

[0035] Specifically, the detachable connection method can be a snap-on connection, a threaded connection, etc., to ensure that the waterproof cover and the grinding chamber can fit tightly and effectively prevent water from entering.

[0036] Furthermore, in a preferred embodiment of an intelligent food waste disposer of the present invention, a weighing device 8 is also provided inside the frame 1, which can weigh the garbage thrown in each time; the controller 7 is connected to the weighing device 8 by signal, and the amount of garbage thrown in each time is obtained through the weighing device 8, and the total amount of garbage in the waste solid collection device 4 is counted, and the total humidity in the waste solid collection device 4 is calculated by counting the amount of garbage entering the waste solid collection device 4 from the garbage bin each time and the single humidity.

[0037] Furthermore, in a preferred embodiment of the intelligent food waste disposer of the present invention, the controller 7 is a PLC control system or a single chip microcomputer.

[0038] The controller can calculate the total humidity in the barrel by counting the amount of garbage each time and the single humidity; when the material humidity measured by the humidity detector is 0-40%, the controller controls the valve to open; when the material humidity measured by the humidity detector is greater than 40%, but if the controller calculates that the humidity of the total material is still lower than 40% after the current batch of garbage enters, the dehydration system will not be started. After staying for 5-10 minutes, the controller controls the valve to open and the garbage enters the waste solid collection device 4; when the material humidity measured by the humidity detector is greater than 40%, and the controller calculates that the total humidity of the current batch of garbage enters the waste solid collection device 4, the controller controls the dehydration system to start and dehydrate the waste. When the garbage humidity drops below 40%, the dehydration system is closed and the valve is opened within 0-60 seconds, with 30-60 seconds being preferred.

[0039] The intelligent kitchen waste disposer of the present invention determines the type of garbage through humidity data collected by a humidity detection device, dehydrates organic garbage with high humidity, realizes the automated design of organic waste dehydration, reduces the humidity of kitchen waste, alleviates the difficulty of subsequent treatment of kitchen waste, and reduces the harm of kitchen waste to the environment; by counting the amount of garbage put in each time and the single humidity, calculating the total humidity in the barrel, controlling the switch and the drying system, the intelligent dehydration of kitchen waste is realized, the energy consumption is reduced, and the dehydration cost is saved.
