[0032] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0033] The embodiment of the utility model provides an organic fertilizer processing device with adjustable pH value, which comprises a box 1, in which domestic waste that can be used to make organic fertilizer is placed, including but not limited to kitchen waste, leaves, crop straw, etc. The organic waste reacts and degrades in the box 1 to generate organic fertilizer.

[0034] like Figure 1 As shown, the organic fertilizer processing device also includes a pH value adjustment component 4, a pH value detection component 5 and a control component 6.

[0035] Continue to combine Figure 1, the pH value adjustment component 4 includes a first cavity 412, a second cavity 413 and a fluid delivery component. The first cavity 412 is used to contain an acidic solution, and the first cavity 412 is connected to the housing 1 through a first pipeline 42. The second cavity 413 is used to contain an alkaline solution, and the second cavity 413 is connected to the housing 1 through a second pipeline 43. The fluid delivery component is used to provide power to the acidic solution flowing through the first pipeline 42 and the alkaline solution flowing through the second pipeline 43, so that the acidic solution in the first cavity 412 and the alkaline solution in the second cavity 413 can be respectively delivered into the housing 1 as needed.

[0036] The pH value detection component 5 is arranged on the box body 1 and extends into the box body 1, and is used for real-time detection of the pH value of the mixture 9 (a mixture of organic waste and microorganisms) in the box body 1, and generates a detection signal including the pH value.

[0037] The control component 6 is connected to the fluid delivery component and the pH value detection component 5 respectively, and receives the detection signal generated by the pH value detection component 5. The control component 6 is used to control the fluid delivery component to deliver the acidic solution in the first cavity 412 into the housing 1 through the first pipeline 42 when the pH value contained in the received detection signal is greater than the first threshold value, and is used to control the fluid delivery component to deliver the alkaline solution in the second cavity 413 into the housing 1 through the second pipeline 43 when the pH value contained in the received detection signal is less than the second threshold value. The first threshold value is greater than or equal to the second threshold value. When the first threshold value and the second threshold value are equal, both are 7. The first threshold value can also be selected as a value greater than 7 and close to 7, and the second threshold value can also be selected as a value less than 7 and close to 7.

[0038] The organic fertilizer processing device of the embodiment of the utility model can not only detect the pH value of the mixture 9 (organic fertilizer) in the box 1 in real time by setting the pH value adjustment component 4 and the pH value detection component 5, but also adjust the pH value of the mixture 9 when necessary, so as to control the pH value of the organic fertilizer finally produced, avoid harming plants, and destroy soil nutrients.

[0039] In some embodiments, the combination Figure 1, the pH value adjustment component 4 also includes a third cavity 414, which is used to hold a neutral solution, and the third cavity 414 is connected to the housing 1 through a third pipeline 44. The fluid delivery component is also used to provide power to the neutral solution flowing through the third pipeline 44, so that the neutral solution in the third cavity 414 can be delivered to the housing 1. The control component 6 is also used to control the fluid delivery component to deliver the neutral solution in the third cavity 414 to the housing 1 through the third pipeline 44 when the pH value contained in the received detection signal is greater than the first threshold value (alkaline or alkaline) or the pH value contained in the detection signal is less than the second threshold value (acidic or acidic). By providing the third cavity 414 for holding a neutral solution, a neutral solution can also be delivered to the housing 1 when the pH value of the mixture 9 in the housing 1 is greater than the first threshold value or the pH value is less than the second threshold value, so as to dilute the mixture 9 and achieve the purpose of changing the pH value of the mixture 9.

[0040] In some embodiments, Figure 1 As shown, the first pipeline 42 is provided with a first solenoid valve 421, the second pipeline 43 is provided with a second solenoid valve 431, and the third pipeline 44 is provided with a third solenoid valve 441; the first ends of the first pipeline 42, the second pipeline 43 and the third pipeline 44 are respectively connected to the first cavity 412, the second cavity 413 and the third cavity 414, and the ends of the first pipeline 42, the second pipeline 43 and the third pipeline 44 are respectively connected to one end of the main pipeline 46 through the four-way valve 45, and the other end of the main pipeline 46 extends into the top of the box body 1. The fluid delivery assembly includes a pump body 47, which is arranged on the main pipeline 46. The control component 6 is also connected to the first electromagnetic valve 421, the second electromagnetic valve 431 and the third electromagnetic valve 441 respectively. The control component 6 is used to control the first electromagnetic valve 421 and / or the third electromagnetic valve 441 to open when the pH value contained in the received detection signal is greater than the first threshold value. The control component 6 is also used to control the second electromagnetic valve 431 and / or the third electromagnetic valve 441 to open when the pH value contained in the received detection signal is less than the second threshold value. By respectively arranging electromagnetic valves on the first pipeline 42, the second pipeline 43 and the third pipeline 44, the conduction or cutoff of each pipeline can be automatically controlled to accurately deliver the required solution into the box 1.

[0041] Of course, it is understandable that the main pipeline 46 can also be eliminated, and the ends of the first pipeline 42, the second pipeline 43 and the third pipeline 44 respectively extend into the top of the box body 1, and pump bodies 47 are respectively set on the first pipeline 42, the second pipeline 43 and the third pipeline 44.

[0042] like Figure 1 As shown, a nozzle 48 is disposed at the other end of the main pipeline 46 , and the solutions from the first cavity 412 , the second cavity 413 and the third cavity 414 can be evenly sprayed onto the mixture 9 in the box 1 through the nozzle 48 .

[0043] The specific structural form of the first cavity 412, the second cavity 413 and the third cavity 414, as well as the arrangement positions of the three are not specifically limited. They can be selected and determined according to actual needs. In some embodiments, Figure 1 As shown, a shell 41 is arranged on the side of the box body 1, and a partition 411 is arranged in the shell 41. The partition 411 divides the shell 41 into a first cavity 412, a second cavity 413 and a third cavity 414 arranged in parallel. The first pipeline 42, the second pipeline 43 and the third pipeline 44 are arranged in parallel vertically and are all located below the shell 41. In this way, the structure can be simplified and the overall structure is more compact.

[0044] The specific form of the pH value detection component 5 can be selected according to actual needs. For example, the pH value detection component 5 can include a pH value sensor. The pH value sensor can be arranged on the bottom wall of the box 1 and extend into the bottom of the box 1. The number of pH value sensors can be one or more.

[0045] In some embodiments, Figure 2 As shown, the organic fertilizer processing device also includes a filter assembly 7, and the filter assembly 7 includes a heating component 72, a heat dissipation component 73, a filter component and a fan 76 connected in sequence through a gas pipeline 71. One end of the gas pipeline 71 is connected to the top of the box body 1. Specifically, one end of the gas pipeline 71 can be extended into the box body 1 from the side wall of the box body 1 close to the top, or a first air outlet 11 is opened on the side wall of the box body 1 close to the top, and one end of the gas pipeline 71 is connected to the first air outlet 11; the other end of the gas pipeline 71 is connected to the outside, so that the gas in the box body 1 is filtered by the filter assembly 7 and then discharged. By setting the filter assembly 7, the gas generated in the organic fertilizer production process in the box body 1 can be filtered and purified before being discharged to avoid pollution to the environment.

[0046] The heating component 72 may include a heating chamber and a heating tube disposed in the heating chamber. The heating tube may heat the temperature in the heating chamber to above 100 degrees, so that the gas generated in the box 1 first enters the heating chamber for high temperature disinfection and sterilization.

[0047] The heat dissipation component 73 may include a heat sink, through which most of the heat carried by the gas after high-temperature disinfection and sterilization is dissipated, thereby reducing the temperature of the gas and avoiding reducing the service life of the filter component when the high-temperature gas subsequently passes through the filter component.

[0048] In some embodiments, the filter assembly 7 includes two filter components, namely a first filter component 74 and a second filter component 75. The first filter component 74 is filled with a filter material 743 for absorbing moisture and odor; the second filter component 75 is a filter net; in the flow direction of the gas, the first filter component 74 is located upstream of the second filter component 75. The filter material 743 in the first filter component 74 can absorb moisture and odor in the gas, and the filter material 743 can be selected from activated carbon or solid alkali. The filter net can further filter dust and other substances in the gas and further purify the air, improve the filtering effect, and finally be discharged to the outside by the fan 76.

[0049] like Figure 3 As shown, the first filter component 74 includes a cylinder 741, in which a spacer 742 is spirally distributed along the axial direction, and a filter material 743 is filled in the cylinder 741. In this way, when the gas flows through the first filter component 74, the gas passes through the spiral spacer 742 to extend the flow path and fully contact the filter material 743, thereby improving the filtering efficiency.

[0050] In some embodiments, Figure 2 As shown, the organic fertilizer processing device also includes a stirring assembly 8, which includes a stirring rod 81 arranged in a transverse direction in the housing 1 and a driving mechanism 83 for driving the stirring rod 81 to rotate, and a plurality of stirring blades 82 are arranged on the stirring rod 81 along its axial direction. The stirring rod 81 can be located in the middle and lower part of the housing 1, and the plurality of stirring blades 82 are arranged in a staggered manner in the radial direction of the stirring shaft, so that the mixture 9 in the housing 1 can be fully stirred, so that the mixture 9 is uniform, and the pH value detected by the pH value adjustment component 4 can accurately represent the actual pH value of the mixture 9. The driving mechanism 83 can, for example, be a motor, and the motor is connected to the stirring rod 81 through a transmission mechanism. The specific structural form of the transmission mechanism is not limited, for example, the transmission mechanism can include a transmission wheel and a driving wheel, and the transmission wheel and the driving wheel are connected through a transmission belt 84, and the transmission wheel is arranged at one end of the stirring rod 81 extending outside the housing 1, and the driving wheel is arranged on the output shaft of the motor. When the motor is started, it can drive the driving wheel to rotate, and the driving wheel drives the driving wheel and the stirring rod 81 to rotate together through the transmission belt 84, thereby realizing the stirring of the mixture 9 in the housing 1.

[0051] In some embodiments, the combination Figure 1The organic fertilizer processing device also includes a shell 2 arranged on the side of the box body 1, and an annular cavity 21 is formed between the shell 2 and the outer peripheral wall of the box body 1. The pH value adjustment component 4 and the filter component 7 are respectively arranged in the annular cavity 21. The shell 2 is provided with a second gas outlet near the lower part, and the other end of the gas pipeline 71 is connected to the second gas outlet. The gas in the box body 1 is filtered by the filter component 7 and then discharged to the outside through the second gas outlet. A bottom shell can also be provided on the bottom side of the box body 1, and the driving mechanism 83 is arranged in the space between the bottom side of the box bottom and the bottom shell, and the transmission mechanism is arranged in the annular cavity 21. The layout structure is compact and reasonable.

[0052] like Figure 1 As shown, a box cover 3 is arranged on the top of the box body 1, and the control assembly 6 can be arranged on the inner side of the box cover 3. The main pipeline 46 can extend upward into the box cover 3, and bend downward to extend into the box body 1 from the top of the box body 1.

[0053] The pH value adjustment working process of the organic fertilizer processing device of the utility model embodiment is as follows:

[0054] When the user needs to adjust the pH value, the stirring component 8 starts to stir the mixture 9 in the box 1 evenly, and the pH value detection component 5 detects the pH data in real time and feeds it back to the control component 6;

[0055] When the pH value detection component 5 detects that the pH value of the mixture 9 is less than the first threshold value (acidic), the control component 6 controls the pump body 47 to start, the second solenoid valve 431 is opened, and the pump body 47 sprays the alkaline solution in the second cavity 413 onto the organic waste mixture 9 through the nozzle 48, and mixes the mixture evenly under the stirring action of the stirring component 8;

[0056] When the pH value detection component 5 detects that the pH value of the mixture 9 is greater than the second threshold value (alkalinity), the control component 6 controls the pump body 47 to start, the first solenoid valve 421 opens, and the pump body 47 sprays the acid solution in the first cavity 412 onto the organic waste mixture 9 through the nozzle 48, and mixes the mixture evenly under the stirring action of the stirring component 8;

[0057] When the pH value detection component 5 detects that the pH value of the mixture 9 is less than the first threshold value or greater than the second threshold value, the control component 6 can also control the third solenoid valve 441 to open, and the pump body 47 sprays the neutral solution in the third cavity 414 onto the organic waste mixture 9 through the nozzle 48, and mixes it evenly under the stirring action of the stirring component 8 to dilute the mixture 9, thereby achieving the purpose of pH value regulation.

[0058] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
