Description

Technical Field

[0001] The utility model relates to the technical field of organic composting and water-fertilizer, in particular to a composting and water-fertilizer integrated device. Background Art

[0002] In recent years, my country's animal husbandry has developed rapidly. Over-concentrated animal husbandry has led to overproduction of livestock and poultry manure in some areas. Traditional composting methods are unable to absorb it, and large-scale stacking has caused serious pollution to the atmosphere, soil and water environment. Animal manure is rich in organic matter and nutrients such as nitrogen, phosphorus and potassium, which can meet the needs of crops for multiple nutrients during growth. Therefore, livestock and poultry manure can be used for composting.

[0003] Composting refers to a biochemical process that utilizes naturally occurring microorganisms to controllably transform biodegradable organic matter in solid waste into stable humus. Composting, with its advantages of low energy consumption and minimal pollution, is a "low-carbon waste" disposal method. Fertilizer is a fertilizer made by adding composted manure to water, allowing crops to absorb both water and nutrients. Integrated fertilization combines irrigation and fertilization based on soil characteristics and crop growth patterns, ensuring timely and appropriate water and nutrient needs are met.

[0004] In the prior art, Chinese utility model patent CN215517207U discloses a composting device with a reaction chamber and positive and negative electrodes, comprising a reactor, a positive electrode component, a negative electrode component, and an aeration tube. The reactor is used to store the compost, and the aeration tube aerates the compost in the reaction chamber, generating oxygen through water electrolysis to promote composting. Chinese utility model patent CN215712685U discloses a composting device with a screening unit. The screening unit includes a feed hopper, a boss, a filter plate, a slide bar, a rectangular long ring, and a power assembly. The feed hopper is arranged on the upper side of the composting tank in the front-to-back direction, with its lower end connected to the feed inlet. A boss is provided on each side of the interior. The upper side of the two bosses slides in the left-right direction to connect to the filter plate. The power assembly drives the rectangular long ring to slide in the left-right direction, drives the slide bar to slide, and then drives the filter plate to slide on the upper side of the boss, so that large particles in the material to be processed are screened out. Chinese utility model patent CN 220078941 U discloses a composting device with a breathable box, including a breathable box body, a transmission assembly, and a pile collection bag. The transmission assembly includes a V-shaped folding rod and a pedal. The V-shaped folding rod includes a bottom rod body and a side rod body that together form an acute angle. After the pedal rotates, it is driven by the transmission of the gear structure to rotate, driving the pile collection bag to rotate. The acute angle structure ensures that the pile collection bag remains horizontal after rotation, realizing rapid transfer of compost.

[0005] The above-mentioned prior arts all adopt a single composting device, which only performs a single operation of composting materials, and does not perform further operations on the composted materials, resulting in a long fertilizer production cycle. Utility Model Content

[0006] The problem to be solved by the utility model is to provide a composting and water-fertilizer integrated device, which solves the problem that fertilizer needs to be transferred during the composting and water-fertilizer production process and the fertilizer production cycle is long.

[0007] The utility model adopts the following technical solution: a composting and water-fertilizer integrated device, comprising a box, a compost layer, a water-fertilizer layer, and a discharge port; the box is divided into an upper layer and a lower layer, which are connected in the middle by a stretchable loose-leaf board;

The grid stirrer is connected to the shaft to stir the compost. The pH value and temperature of the compost are detected in real time by pH sensors and temperature sensors, and displayed on the data display screen.

[0009] The lower layer of the box includes a water and fertilizer layer. After opening the pull-out loose-leaf plate, organic fertilizer falls into the water and fertilizer layer, where it is mixed with water in proportion and stirred by a water and fertilizer mixer to produce water and fertilizer at the discharge port.

[0010] Furthermore, the outer shell of the box is made of double-layer stainless steel, and the top of the outer top of the upper layer of the box also includes a top cover. The compost body is placed in the box by opening the top cover, and the gas is isolated from entering and exiting the box by closing the top cover to ferment the compost body.

[0011] Furthermore, the blower ventilation system supplies fresh air into the box by setting a blower port connected to a blower on the upper right side of the upper layer of the box; a ventilation exhaust port is set at the rear of the upper layer of the box to discharge fermentation waste gas in the box and control the oxygen concentration in the box; a ventilation fan is also set above the upper layer of the box to discharge the gas in the upper space of the box and reduce the temperature of the upper space of the box.

[0012] Furthermore, the pH sensor and temperature sensor inside the box are placed in the compost layer to detect the pH value and temperature of the compost in the upper layer of the box in real time, adjust the temperature of the compost through the air blast port and the ventilation exhaust port, change the pH value of the compost by injecting acidic or alkaline solutions, and display the real-time pH value and temperature on the data display screen.

[0013] Furthermore, a visual sampling window is provided at the front of the upper layer of the box body to observe the color, particle size and maturity of the compost body, and compost body samples can be taken through the visual sampling window for testing.

[0014] Furthermore, the rotating shaft is arranged in the middle of the compost layer and is integrated with the grid stirrer. The rotation of the rotating shaft drives the grid stirrer to rotate, stir the compost body, provide a gas exchange channel, and allow the compost body to fully contact with oxygen.

[0015] Furthermore, a control button is provided on the upper front of the box to control the opening and closing of the retractable loose-leaf plate; the retractable loose-leaf plate is located at the lower part of the compost layer, supporting the compost body, and the fermented organic fertilizer is leaked into the water and fertilizer layer at the lower layer of the box through the control button.

[0016] Furthermore, the inner wall of the upper bottom layer of the box body also includes a vertical lifting flap track and a horizontal extension flap track, which cooperate to control the lifting and contraction and the lowering and expansion of the retractable loose-leaf flap.

[0017] Furthermore, the lower layer of the box includes a flip-top water injection port located on the top surface. After water is injected through the flip-top water injection port, the organic fertilizer is mixed with water in proportion in the water-fertilizer layer, and the mixed water-fertilizer is taken out through the discharge port.

[0018] Furthermore, the lower layer of the box also includes: a water-fertilizer mixer located inside the water-fertilizer layer and a discharge port located at the lower side.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In one embodiment of the present invention, a composting and water-fertilizer integrated device, such as Figure 1 As shown, it includes: a top cover 1, an air blast port 2, a ventilation and exhaust port 3, a control button 4, a visual sampling window 5, a retractable loose-leaf board 6, a water and fertilizer mixer 7, a data display screen 8, a pH sensor 9, a temperature sensor 10, a rotating shaft 11, a compost layer 12, a grid mixer 13, a vertical lifting flap track 14, a horizontal extending flap track 15, a water and fertilizer layer 16, a ventilation fan 17, a discharge port 18, and a flip-top water inlet 19.

[0028] Among them, the top cover 1 is located at the top outside the box, which serves as a closed environment and isolates the gas from entering and exiting; the air vent 2 is located in the upper right part of the box, which is used for the input of air into the box; the ventilation and exhaust vent 3 is located in the upper front part of the box, which is used for the discharge of fermentation waste gas in the box; the ventilation fan 17 is located above the device, which is used to reduce the temperature of the upper fermentation chamber.

[0029] The control button 4 is located on the upper front of the upper layer of the box body, and is used to control the opening and closing of the retractable loose-leaf plate 6; the retractable loose-leaf plate 6 is located at the lower part of the compost layer, and is used to support the compost body and leak the organic fertilizer into the lower water fertilizer layer when fermentation is completed.

[0030] The visual sampling window 5 is located at the front of the box body and is used to observe the degree of feces fermentation (the morphology and hyphae state of organic fertilizer) and to extract samples for testing under different temperatures, humidity and pH.

[0031] The pH sensor 9 and the temperature sensor 10 are placed inside the compost layer 12 and are connected to the data display screen 8. The data display screen 8 is partially placed in the center (outside) of the front of the box. The pH sensor 9 and the temperature sensor 10 respectively detect the pH value and temperature of the upper layer of the box in real time and display them in real time through the data display screen 8.

[0032] The composting layer 12 is located in the upper box and is used to hold feces for fermentation and composting; the grid stirrer 13 is located inside the composting layer and is used to stir the compost and provide a channel for gas exchange so that the compost is fully exposed to oxygen; the rotating shaft 11 is located in the middle of the composting layer 12 and is integrated with the grid stirrer 13, driving the grid stirrer 13 to rotate.

[0033] The vertical lifting plate track 14 is located on the inner wall of the composting layer 12 box and is used to control the lifting of the central axis of the stretching plate 6;

[0034] The horizontally extending flap track 15 is located on the bottom inner wall of the compost layer 12 box body, and cooperates with the vertically lifting flap track 14 to control the rising, contraction, and lowering and unfolding of the stretchable loose-leaf board 6.

[0035] The flip-top water injection port 19 is located at the top of the lower layer of the device box and is used to inject clean water into the lower layer of the device box.

[0036] The water-fertilizer layer 16 is located at the lower layer of the device box and is used to mix organic fertilizer and water in proportion to configure the water-fertilizer; the water-fertilizer stirrer 7 is located inside the water-fertilizer layer and is used to mix and stir the organic fertilizer and water; the discharge port 18 is located at the lower layer of the device, and the water-fertilizer mixed with clean water and fertilizer can be taken out here.

[0037] The operating principle of the composting and water-fertilizer integrated device of this embodiment is as follows:

[0038] After removing the top cover 1 of the device, add the composting materials and fermentation bacteria, and close the top cover after filling. After a period of time, the organic matter in the feces is consumed by the bacteria in the upper layer of the box, leaving inorganic salts that can be directly absorbed by crops.

[0039] During this process, the temperature in the upper layer of the box gradually increases as the organic matter decomposes. The higher temperature can kill other bacteria and ensure the harmlessness of the fertilizer. During the fermentation of the fertilizer, fresh air can be sent into the box through the blower connected to the blower port 2 at the front of the box to ensure the amount of oxygen required for fermentation. A row of ventilation and exhaust ports 3 are provided at the rear of the box to discharge the waste gas generated during the fermentation process and can also be used to control the oxygen concentration in the box.

[0040] A pH sensor 9 and a temperature sensor 10 are provided at the bottom of the upper layer of the box. The monitoring results can be displayed in real time on the data display screen 8. When the temperature is too high or too low, the temperature can be adjusted by the blower and ventilation fan 17; the pH of the composting chamber can be changed by injecting acidic or alkaline solutions; and the success rate and efficiency of composting can be promoted by adjusting the appropriate temperature and pH value for the composting chamber.

[0041] A visual sampling window 5 is provided below the vent to observe the color, particle size and degree of maturity of the fertilizer, and to sample the fertilizer for testing. During the decomposition process, the grid stirrer 13 is activated to fully mix the fermentation bacteria with the feces, reducing the decomposition time and increasing the composting efficiency.

[0042] After the feces are fully decomposed, the retractable loose-leaf plate 6 in the box is opened. In order to make the organic fertilizer fall, the device is equipped with a pulley track device on the compost layer, and the retractable loose-leaf plate is placed at the bottom of the composting device. After the composting is completed, the track system is started to control the vertical lifting loose-leaf plate 14 to slide upward, and at the same time, the horizontal stretching loose-leaf plate track 15 moves closer to the middle, and the retractable loose-leaf plate 6 is closed to make the organic fertilizer fall.

[0043] Then close the stretch-type loose-leaf plate 6, inject clean water through the flip-top water inlet 19 according to a certain proportion, start the water-fertilizer mixer 7, and after the stirring is completed, take out the fertilizer through the discharge port 18.

[0044] Specifically, when using the integrated composting and water-fertilizer device of this embodiment, preparation work must first be performed:

[0045] 1. Connect the blower to the air outlet and perform a ventilation test;

[0046] 2. Verify whether the instruments on the upper layer of the device box can operate normally;

[0047] 3. Open the top cover 1 of the device, put the pretreated poultry and livestock manure into it and inoculate the bacteria involved in manure fermentation. After the raw materials are completely placed in the upper layer of the device and the inoculation is completed, close the top cover 1 of the device to keep the device airtight to prevent other bacteria from entering the device and affecting the fermentation.

[0048] After the preparation work is completed, air is slowly introduced into the device through a blower to provide sufficient oxygen for the microorganisms, at which point the microorganisms begin to ferment.

[0049] When fermentation begins, start the upper grid agitator to fully mix the inoculated bacteria with the feces to be fermented. At the same time, it can also allow the bacteria to fully contact with the air, thereby increasing the activity of the bacteria and the fermentation rate.

[0050] During the fermentation process, samples are taken through a visual sampling window, and the degree of fecal fermentation is judged by observing the physical properties of the feces such as color, hardness, and particle size.

[0051] The user observes the temperature and pH of the feces during the fermentation process of the upper compost layer of the box through the data display screen 8, and ensures that the fermentation process is in the best conditions by changing the temperature and pH of the feces.

[0052] If the temperature is too low, the user can use an external blower to blow hot air into the upper device, thereby increasing the temperature of the upper composting chamber. If the temperature is too high, the user can turn on the ventilation fan and increase the blower speed to reduce the temperature of the upper composting chamber. If the pH is not within the appropriate range, the user can open the sampling port of the visual sampling window and inject pH adjustment liquid into the fertilizer. The grid agitator will mix it thoroughly with the fertilizer to adjust the pH of the fertilizer to the normal range.

[0053] After the feces are completely decomposed, the user opens the retractable loose-leaf plate 6 in the box, and by starting the track system, controls the vertical lifting loose-leaf track 14 to slide upward while the horizontal extending loose-leaf track 15 moves toward the middle. The retractable loose-leaf plate 6 opens to allow the organic fertilizer to fall, and the fermented fertilizer falls into the lower layer of the box under the action of gravity, and is mixed with water and fertilizer through the water-fertilizer mixer 7.

[0054] After the fertilizer falls into the lower device, the user injects water through the flip-top water injection port 19 at a ratio of 800 to 1000:1 according to the quality of the fertilizer. After the water injection is completed, the lower water-fertilizer stirrer 7 is started to mix the water and fertilizer. After waiting for 5 to 10 minutes (select a suitable time according to the volume of water and fertilizer to be mixed), the water-fertilizer stirrer 7 is turned off, and the mixed water and fertilizer are taken out through the discharge port 18 after the mixed water and fertilizer are stable.

[0055] In summary, the utility model of the integrated fertilizer and water-fertilizer device is applicable to the field of agricultural composting and fermentation and the technology of integrated fertilizer and water-fertilizer. By connecting the compost and water-fertilizer devices in series, the problem of the need to transfer fertilizer during the compost-water-fertilizer production process and the long fertilizer production cycle is solved. At the same time, a display screen and a visual sampling window are provided, which can display the temperature and pH value of the fermentation process in real time for timely regulation, and can observe and sample the fertilizer at any time. This solves the pollution caused by animal feces and the problems of long composting cycles and the inability to observe the degree of maturity, and further supplements the technology in the field of organic fertilizer and water composting on the market.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
