Description

Kitchen waste on-site biological digestion and earthworm production equipment

Technical Field

The utility model belongs to the technical field of garbage treatment, and particularly relates to equipment capable of producing earthworms while consuming kitchen garbage.

Background

The kitchen waste is waste generated in activities such as daily life, food processing, food service, unit catering and the like, comprises discarded leftovers, vegetable leaves, fruit peels, egg shells, tea leaves, bones and the like, and is mainly sourced from household kitchens, restaurants, markets and the like. With the improvement of living standard of people, the output of kitchen garbage is continuously increased. Because the kitchen garbage has high water content, organic matter content, grease and salt content, the kitchen garbage is easy to ferment, deteriorate and rot, emits odor, pollutes living environment, is easy to breed germs and generate toxin, and has potential threat to the health of people.

At present, domestic kitchen waste is mainly subjected to centralized landfill along with common waste, microbial-added centralized composting, boiler incineration, biological fermentation to prepare feed, crushing and direct discharge along with water for treatment. The treatment methods have the disadvantages of poor economic benefit and low resource utilization rate, and most importantly, many places cannot be applied due to condition limitation, and are difficult to popularize comprehensively.

Earthworms belong to omnivorous land-link animals, and are eaten by other people except glass, plastic and rubber, such as soil bacteria, fungi and other microorganisms, humus, animal wastes and other substances and decomposition products of the substances. Therefore, various livestock and poultry such as pigs, cattle, sheep, chickens, ducks and the like, human excrement, leftovers (as little salt as possible), vegetable leaves, melon peels, fruits, waste paper, vinasse, sugar residues, wood chips, crop straws such as corns, wheat, rice and the like, and earthworms such as various wild grass leaves and the like can be eaten. The earthworms can survive for 1 to 3 years, if the conditions are suitable and the food is sufficient, 3000 earthworms can be bred by 1 earthworm in one year in 2000-3000. The earthworm is a very good Chinese medicinal material, contains various proteases such as streptokinase, lumbrokinase and the like, and has the effects of clearing heat, arresting convulsion, reducing blood pressure, relieving cough and asthma and promoting urination. Has good therapeutic effects on blood coagulation disorder, apoplexy induced sequelae, arteriosclerosis, hypertension, blood hyperviscosity, epilepsy, convulsion, sore throat, scabies, and pain due to traumatic injury. It has been determined that the earthworm proteins comprise about 53.5% to 65.1% by dry weight, the fats comprise about 4.4% to 17.38%, the carbohydrates comprise about 11% to 17.4%, and the ash comprises about 7.8% to 23%; the earthworm also contains abundant vitamin D (about 0.04-0.073% of fresh weight), calcium and phosphorus (about 0.124-0.188% of fresh weight) and other mineral elements; the earthworm also contains various medicinal components such as earthworm toxin-removing agent, xanthine, antihistamine and vitamin B. The earthworm can be processed into various functional health products, such as bioactive peptide and cosmetics; can produce high-quality alternative feed for animals such as fish, chicken and pig; the earthworm fertilizer is a high-quality organic fertilizer without any pollution, and can well improve soil.

The kitchen garbage such as leftovers, bones, vegetable leaves, fruit peels, egg shells, tea leaves and the like which are rich in nutrition is undoubtedly a high-quality raw material for raising and producing earthworms. However, earthworms are afraid of salt and spicy, and kitchen waste with salty or spicy taste cannot be directly used for raising earthworms.

Considering the life habit and value of earthworms, it is a good method to treat kitchen garbage with earthworms and recycle the earthworms, and an apparatus for carrying out the method is needed.

As shown in FIG. 4, the working process of the device for on-site biological digestion and earthworm production of kitchen waste of the utility model is as follows: soaking, washing for desalination, removing spiciness by ozone, squeezing for dehydration, screening, crushing, treating earthworm for digestion, outputting earthworms and processing and utilizing earthworms, specifically, firstly, classified kitchen garbage is poured into a soaking, desalting and spiciness-removing elliptic barrel A through a feed inlet 6, a three-way valve 3 is controlled by a comprehensive controller G to inject tap water, a spiral stirrer I1 continuously stirs, and a drain valve 7 is controlled to naturally drain liquid in a barrel body 30 after lasting for 5-20 minutes, or the drain valve 7 is opened while the tap water is injected, and clean water is injected and water is stirred while draining, so that salt in the kitchen garbage is removed more quickly; the ozone water generator 2 is operated through the integrated controller G, the ozone water is injected according to the method and then soaked for 20-30 minutes, so that the spicy ingredients in the kitchen garbage are decomposed and removed, and the liquid discharge valve 7 is controlled to discharge the liquid with ozone. In order to prevent ozone remaining in the kitchen garbage from influencing normal feeding of earthworms in later period, clear water is injected again to stir and clean, and then liquid is discharged. When the discharge door 8 is opened, the desalted, spicy and non-ozone residual garbage is continuously discharged through the spiral stirrer I1, and falls into the extrusion dehydration container B through the feed inlet 9, the comprehensive controller controls the electric hydraulic driving device 11 and the compression plate 12 to forcibly extrude the garbage, most of moisture in the garbage is continuously discharged along the plurality of small holes 10 at the bottom, when the garbage is dry (the water content is 40-60%), the garbage discharge door 13 is opened, the dry garbage is discharged and falls into the separation sieve C through the feed inlet 16, the comprehensive controller G opens the separation sieve C, the spiral stirrer II 14 with the columnar bulge 15 rapidly rotates to stir and loosen the garbage, so that garbage fine particles continuously leak out of the sieve holes 17 at the lower half part, and directly fall into the garbage absorption trolley E along the hopper 18 below the bottom; meanwhile, large garbage which cannot be leaked down, such as bones and the like, is pushed forward to the direction of the large garbage discharging door 19 by the second spiral stirrer 14, the large garbage discharging door 19 is opened, the large garbage is discharged into the crusher D to be crushed, and the garbage crushed into fine particles directly falls into the garbage accommodating trolley E and then enters the subsequent earthworm accommodating process.

The garbage absorption trolley E is used for containing 30-50 cm-thick desalted spicy kitchen waste, then dozens of to hundreds of or even more 'Daping II' earthworms with better comprehensive properties at present are manually inserted according to the amount of the garbage to be treated and the expected treatment time (the number of the inserted earthworms is large, the absorption treatment garbage is large, the efficiency is higher, and the treatment required time is shorter), the garbage absorption trolley E is placed into a closed absorption chamber F, a traction hook of a traction cable chain system 26 is connected with the garbage absorption trolley E, and a graphene far infrared heating module 22, an air humidifier 23, a cold and hot air input device (air conditioner) 20 and an exhaust fan 21 are regulated and controlled through a comprehensive controller and a temperature and humidity sensor 24. When the temperature is lower, the temperature in the closed absorption room is raised, and when the temperature is higher, the air is changed to lower the temperature; the humidifier humidifies when the humidity is lower, and the exhaust fan dehumidifies when the humidity is higher; the air temperature is kept at 26-27 ℃ throughout the year in the closed digestion room, the air humidity is kept at 60-80% (the substrate humidity is 40-60%), ventilation is carried out 2-4 times every day, 10-15 minutes each time, and at least the LED red light lamp is turned on for 0.5 hour each day, so that sufficient oxygen and proper red light irradiation are provided for the growth and the propagation of the earthworms, the earthworms grow and develop at the fastest speed, and the kitchen waste is rapidly digested. When the earthworms basically consume the kitchen waste in the waste consuming trolley E and need to take the earthworms out of the closed consuming room F, or when a kitchen waste consuming trolley to be treated, which is newly connected with the earthworms, needs to be put into the closed consuming room F for cultivation, the waste consuming trolley can be moved circularly by controlling the traction cable chain system 26. The kitchen waste is completely converted into earthworms, earthworm excrement and earthworm cocoons after being subjected to earthworm digestion treatment under the most suitable condition, and almost all the kitchen waste is organic matters which can be digested and absorbed by the earthworms due to the extremely strong digestion function of the earthworms, so that the earthworm excrement is extremely little except the earthworms and the earthworm cocoons in the garbage digestion trolley E after being subjected to earthworm digestion.

There are more than 3000 earthworms in the world, 229 earthworms are recorded in China, and the earthworms are distributed almost all over the country. The different types of earthworms have slight difference in feeding property and habit, so that the second-generation earthworms in the Eisenia are the most common earthworms, belong to the miscellaneous food, are easy to survive, fast to develop, strong in adaptability and long in service life, and are suitable for kitchen garbage treatment. Earthworms are fond of warmth, cold, hot, moisture, dryness, darkness, strong light, silence, vibration, sourness, sweetness, acridity, salt and alkali. Generally, the Lumbricus is dormant at 5-30 deg.C and 0-5 deg.C, and dies below 0 deg.C, and stops development below 8 deg.C, preferably 20-27 deg.C and above 32 deg.C, and dies above 40 deg.C. The humidity of the growth substrate is 40-60%, which is equivalent to 60-80% of the air humidity, the pH value is 6-8, and intermittent red light is needed for mass propagation. Sexual maturity can be achieved within about 30 days under the condition of artificial feeding, after male and female mating, earthworm cocoons can be produced in 1.5-4.5 days at 18-25 ℃, when the temperature of earthworm cocoons reaches 220-260 ℃, young earthworms can hatch out, and the full growth period of the earthworms is about 60 days. If the humidity condition meets the temperature control of 26-27 ℃, the growth and development speed of the earthworms can be obviously accelerated, and the whole growth period of the earthworms can be shortened to 50 days or even shorter.

According to the utility model, the rapid growth and reproduction conditions of earthworms can be met to the maximum extent in the aspects of temperature, humidity, illumination and vibration prevention through the design construction and comprehensive automatic control of the closed digestion room F, kitchen waste is desalted, spicy and crushed, all harmful substances to the growth and reproduction of the earthworms in the kitchen waste are removed, especially the kitchen waste decomposed and crushed by adopting ozone water is more beneficial to the digestion and absorption of the earthworms, the air humidity is regulated and controlled to be 60-80% in the closed digestion room, which is equivalent to the kitchen waste humidity to be 40-60%, the temperature is controlled to be higher to be 26-27 ℃, the growth and reproduction speed of the earthworms can be greatly accelerated, the kitchen waste is digested and reproduced at the highest efficiency by the earthworms, and the utilization efficiency of equipment and the comprehensive economic benefit are improved.

The construction scale of the closed digestion room F and the number of the garbage digestion trolleys E depend on the number of kitchen garbage to be treated every day, assuming that at least 1 trolley of kitchen garbage needs to be treated every day, the number of the trolleys is about 50 according to the consideration that the earthworms complete the full growth cycle for about 50 days, so that the operation and management are convenient, and the construction space of the closed digestion room F must be capable of accommodating at least 50 garbage digestion trolleys E to move. Namely, a new trolley needing to be consumed is placed every day, and just one old trolley finishes a full growth cycle of earthworms. Actually, earthworms with a certain growth period are inoculated, after 50 days of culture, most of the earthworms are new earthworms bred by inoculating the earthworms at the previous time, a small number of the newly bred earthworms are taken out to be continuously used for new kitchen garbage digestion treatment, and the produced redundant earthworms are output as byproducts of processing and utilization of traditional Chinese medicinal materials, feeds and the like. If the number of the earthworms manually connected is increased in multiples, the speed of the earthworms for absorbing the garbage is increased in multiples, the garbage absorbing time is greatly shortened, the number of the required trolleys is reduced, and the airtight absorbing room F can be built to be smaller. Because the trolley in the closed digestion room F moves fast in a circulating manner, the growth and reproduction time of earthworms is shortened (the growth and accumulation temperature is less), and the produced earthworms are reduced (the number of young earthworms is increased). If the earthworms are not taken out after the circulation once and are all continuously used for the new kitchen waste digestion treatment, the treatment efficiency of the earthworms can be greatly improved, and only the small and large earthworms or earthworm cocoons in the trolley are probably crossed or appear at the same time.

In the equipment, the high-quality harmless kitchen garbage earthworm feed is prepared through the working procedures of soaking kitchen garbage in clear water, washing for desalting, soaking in ozone water for removing acridity, squeezing for dewatering, rolling for screening and crushing, and then the earthworms are enabled to grow rapidly and breed in large quantities through the optimum earthworm growing and breeding closed feeding environment until the kitchen garbage is completely converted and absorbed by the earthworms. The earthworm part bred from the kitchen waste is used as a seed earthworm to circularly absorb new kitchen waste, and the produced redundant earthworm part is output as an earthworm development and utilization material.

The utility model is suitable for residential communities, hotels and restaurants, tourist attractions, schools, hospitals and the like. The equipment for biologically dissolving and producing the earthworms in situ in the kitchen waste can dissolve the kitchen waste and produce the earthworms at the same time, thereby reducing the transportation cost of the kitchen waste and reducing the environmental pollution.

According to the equipment and the method for biologically dissolving and producing the earthworms in situ by using the kitchen waste, the earthworms are used for biologically dissolving the kitchen waste in situ, so that the kitchen waste transportation cost can be obviously reduced, the environmental pollution is reduced, a large amount of earthworms with high added values can be produced properly in management and operation, and the recovery is realized; the complete equipment is simple, the subsequent investment is not needed after the complete equipment is built, the use and the operation are simple and convenient, the operation cost is extremely low, and the treatment process is tasteless and pollution-free; the device is easy to construct, occupies less land, is intelligently controlled, is very convenient to use and manage, and is convenient to popularize and apply comprehensively.

The above examples are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should be made within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
