Description

Technical Field

[0001] The present invention relates to the technical field of resource utilization of kitchen waste, and particularly to a kitchen waste microbial degradation treatment device capable of monitoring the fermentation stage. Background Art

[0002] Kitchen waste refers to the waste generated in activities such as residents' daily life, food processing, catering services, and unit meal supply. The microbial degradation treatment of kitchen waste relies on specific bacterial communities to decompose organic matter into carbon dioxide, water, and humus. In the microbial degradation treatment process of kitchen waste, an aerobic fermentation system needs to maintain the microbial activity and degradation efficiency through a stirrer, and monitor the data of the fermentation stage in real time through monitoring devices such as temperature sensors, pH sensors, and electrochemical sensors to achieve precise control of different fermentation stages.

[0003] Since the pH sensor usually inserts a probe into the kitchen waste for real-time detection, during the process of the stirrer stirring the kitchen waste, the kitchen waste will continuously impact or wrap the detection probe driven by the stirring, which will not only affect the normal detection of data by the detection probe, but also increase the probability of damage to the detection probe, reducing the detection accuracy of the fermentation stage of the kitchen waste. Summary of the Invention

[0004] Based on this, it is necessary to provide a kitchen waste microbial degradation treatment device capable of monitoring the fermentation stage for the problem that the detection probe in the kitchen waste microbial degradation treatment device capable of monitoring the fermentation stage is easily affected by the kitchen waste, reducing the detection accuracy of the fermentation stage of the kitchen waste.

[0005] A kitchen waste microbial degradation treatment device capable of monitoring the fermentation stage includes a stirring barrel, an electric stirrer, and a controller. The electric stirrer is installed on the top of the stirring barrel, the output shaft of the electric stirrer penetrates into the interior of the stirring barrel, the controller is fixedly connected to the side end of the stirring barrel, a guiding cavity is opened at the top of the stirring barrel, a pH value monitoring mechanism is fixedly connected to the side end of the stirring barrel, and one end of the pH value monitoring mechanism penetrates through the guiding cavity and extends into the interior of the stirring barrel.

[0006] Further, the pH value monitoring mechanism includes an electric lifting component fixedly connected to the side end of the stirring barrel. The lower surface of the electric lifting component is fixedly connected with a closed tube. The bottom of the closed tube penetrates through the guiding cavity and extends into the interior of the stirring barrel. The upper surface of the electric lifting component is fixedly connected with a pH value detector and a driving motor. The detection end of the pH value detector is electrically connected to a detection probe inserted into the interior of the closed tube. The ends of the output shaft of the driving motor and the surface of the detection probe are both fixedly connected with spur gears that mesh with each other. The detection end of the detection probe is fixedly connected with a blocking cylinder rotatably connected to the closed tube. The outer sides of the closed tube and the blocking cylinder are both provided with liquid guiding ports that communicate with each other. A sealing ring is embedded and installed on the inner side of the guiding cavity, and the sealing ring is sleeved on the outer side of the closed tube.

[0007] Further, the number of liquid guiding ports on the outer sides of the closed tube and the blocking cylinder is two each. The two inner liquid guiding ports and the two outer liquid guiding ports are symmetrically distributed on both sides of the axis of the closed tube.

[0008] Further, the included angle formed between the two corners with the farthest distance in the horizontal cross-section of the liquid guiding port and the axis of the closed tube is a sector with an angle of 25 degrees.

[0009] Further, the vertical cross-section shape of the inner bottom wall of the closed tube is conical, and the lowest point of the inner bottom wall of the closed tube is flush with the inner bottom wall of the outer liquid guiding port.

[0010] Further, the horizontal cross-section shapes of the contact parts between the closed tube and the guiding cavity are all circular and match each other.

[0011] Further, the vertical cross-section shape of the inner bottom wall of the inner liquid guiding port is ramp-shaped, and the inclination degrees of the inner bottom wall of the inner liquid guiding port and the inner bottom wall of the closed tube are the same.

[0012] Further, a filter screen is embedded and installed inside the outer liquid guiding port.

[0013] Further, the end of the filter screen facing away from the blocking cylinder is flush with the opening of the outer liquid guiding port facing away from the blocking cylinder.

[0014] Further, the shape of the filter screen is rectangular parallelepiped-shaped, and the filter screen is a component made of L stainless steel material.

[0015] Further, the detection end of the pH value detector is electrically connected to an electrical rotary joint, and the end of the electrical rotary joint facing away from the pH value detector is electrically connected to the detection probe.

[0016] The above-mentioned kitchen waste microbial degradation treatment equipment capable of monitoring the fermentation stage adopts a pH value detection structure with a lifting design. This not only enables the detection probe to be placed above the kitchen waste when the electric stirrer is operating, avoiding the waste from winding and wrapping around the surface of the closed tube during the stirring process, thereby reducing the interference with the detection of the detection probe, but also allows the staff to lower the detection probe to the corresponding depth for detection. This can detect the pH value of materials at different depths, improve the accuracy of monitoring the fermentation stage of kitchen waste, and achieve the directional conversion from waste to organic fertilizer;

[0017] While the electric lifting component lifts and lowers the detection probe, the annular scraping plate rotates under the indirect drive of the threaded column to scrape off the impurities adhering to the surface of the closed tube along the way. This not only keeps the local area of the closed tube passing through always clean, but also uses the rotational centrifugal force to throw off the scraped impurities to ensure that the annular scraping plate can effectively scrape off the impurities. And when the closed tube rises to the highest position, the cleaning component can automatically rinse the detection end of the detection probe, which can wash away the interfering substances such as liquid materials and dirt adhering to the detection end of the detection probe. This not only reduces the probability of the interfering substances solidifying or corroding the detection probe to improve the accuracy of the subsequent detection of the detection probe, but also ensures the effectiveness of the subsequent calibration of the pH value detector, further improving the accuracy of the subsequent detection of the detection probe, and thus increasing the success rate of converting kitchen waste into humus.

The term "and / or" used in the description of the present invention includes any and all combinations of one or more of the related listed items.

[0034] The following combines Figure 1 - Figure 8 to describe the kitchen waste microbial degradation treatment equipment capable of monitoring the fermentation stage of the present invention.

[0035] In one embodiment, a kitchen waste microbial degradation treatment equipment capable of monitoring the fermentation stage includes a stirring barrel 1, an electric stirrer 2 and a controller 3. The electric stirrer 2 is installed on the top of the stirring barrel 1, the output shaft of the electric stirrer 2 penetrates into the interior of the stirring barrel 1, the controller 3 is fixedly connected to the side end of the stirring barrel 1, a guiding cavity 11 is formed at the top of the stirring barrel 1, a pH value monitoring mechanism 4 is fixedly connected to the side end of the stirring barrel 1, and one end of the pH value monitoring mechanism 4 penetrates through the guiding cavity 11 and extends into the interior of the stirring barrel 1.

[0036] Such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown in the figure, the pH value monitoring mechanism 4 includes an electric lifting component 41 fixedly connected to the side end of the stirring barrel 1. The lower surface of the electric lifting component 41 is fixedly connected with a closed tube 42. The bottom of the closed tube 42 penetrates through the guiding cavity 11 and extends into the interior of the stirring barrel 1. The upper surface of the electric lifting component 41 is fixedly connected with a pH value detector 43 and a driving motor 44. The detection end of the pH value detector 43 is electrically connected with a detection probe 45 inserted into the interior of the closed tube 42. The end of the output shaft of the driving motor 44 and the surface of the detection probe 45 are both fixedly connected with spur gears 46 that are meshed with each other. The detection end of the detection probe 45 is fixedly connected with a blocking cylinder 47 rotatably connected to the closed tube 42. Liquid guiding ports 48 that communicate with each other are formed on the outer sides of the closed tube 42 and the blocking cylinder 47; a sealing ring 12 is embedded and installed on the inner side of the guiding cavity 11. The sealing ring 12 is sleeved on the outer side of the closed tube 42. This can not only prevent the cleaning liquid from entering the interior of the stirring barrel 1, but also prevent the fermentation gas inside the stirring barrel 1 from leaking out, forming a technical feature of "dynamic sealing between the closed tube 42 and the sealing ring 12 during the lifting process", and solving the technical problem that the existing detection probe 45 brings out materials and brings in cleaning liquid when lifting and lowering.

[0037] The number of the liquid guiding ports 48 on the outer sides of the closed tube 42 and the blocking cylinder 47 is two. The two inner liquid guiding ports 48 and the two outer liquid guiding ports 48 are symmetrically distributed on both sides of the axis line of the closed tube 42. This can increase the indirect communication area between the detection probe 45 and the outside world to improve the detection accuracy and detection efficiency of the detection probe 45; the included angle formed between the two corners with the farthest distance in the horizontal section of the liquid guiding port 48 and the axis line of the closed tube 42 is a sector with an angle of twenty-five degrees. This can ensure that when the blocking cylinder 47 rotates ninety degrees, the inner and outer liquid guiding ports 48 can be completely misaligned to achieve the effect of sealing the detection probe 45; the vertical section shape of the inner bottom wall of the closed tube 42 is conical, and the lowest point of the inner bottom wall of the closed tube 42 is flush with the inner bottom wall of the outer liquid guiding port 48. This can reduce the residence rate of the liquid material or cleaning liquid inside the closed tube 42 to reduce the influence on subsequent detection; the horizontal section shapes of the contact parts between the closed tube 42 and the guiding cavity 11 are all circular shapes that match each other. This can mutually limit the closed tube 42 and the guiding cavity 11 to ensure that the closed tube 42 drives the detection probe 45 to lift and lower vertically; the vertical section shape of the inner bottom wall of the inner liquid guiding port 48 is a slope shape, and the inclination degree of the inner bottom wall of the inner liquid guiding port 48 is the same as that of the inner bottom wall of the closed tube 42. This can further reduce the residence rate of the liquid material or cleaning liquid inside the closed tube 42 to increase the discharge rate of the liquid material or cleaning liquid.

[0038] A filter screen 49 is embedded and installed inside the outer liquid guide port 48. One end of the filter screen 49 facing away from the blocking cylinder 47 is flush with the opening of the outer liquid guide port 48 facing away from the blocking cylinder 47. This can prevent solid materials in the stirring barrel 1 from entering the liquid guide port 48, not only reducing the burden of the rotation of the blocking cylinder 47, but also reducing the subsequent cleaning burden. The filter screen 49 is in the shape of a cuboid and is a component made of 316L stainless steel material, which can ensure that the filter screen 49 can still operate normally in a corrosive environment to extend the service life of the filter screen 49.

[0039] The detection end of the pH value detector 43 is electrically connected to an electrical rotary joint 410. One end of the electrical rotary joint 410 facing away from the pH value detector 43 is electrically connected to the detection probe 45. This can enable the pH value detector 43 and the detection probe 45 to rotate relative to each other on the basis of maintaining a stable connection to ensure the normal rotation of the blocking cylinder 47.

[0040] Figure 1 and Figure 2 As shown in the figure, an asbestos heat-insulating sheath is sleeved on the side end of the stirring barrel 1. An electric heater is embedded and installed inside the asbestos heat-insulating sheath. The electric heater is in the shape of a spiral and is electrically connected to the controller 3. The top of the stirring barrel 1 is fixedly connected and communicated with a food waste feeding pipe, a microorganism feeding pipe and a gas guide pipe. Sealing caps are sleeved on the ends of the food waste feeding pipe, the microorganism feeding pipe and the gas guide pipe facing away from the stirring barrel 1. The bottom of the stirring barrel 1 is fixedly connected and communicated with an electric plate valve. The bottom of the electric plate valve is fixedly connected and communicated with a discharge pipe. A temperature sensor, an electrochemical sensor and a humidity sensor are embedded and installed on the inner top wall of the stirring barrel 1. The temperature sensor, the electrochemical sensor and the humidity sensor can respectively and real-time detect the temperature, the generated gas concentration and the humidity of the materials in the stirring barrel 1. Then, the staff can adjust the internal temperature of the stirring barrel 1 in real time through the electric heater, and adjust the oxygen content and humidity between the materials by adjusting the stirring frequency of the electric stirrer 2 to ensure that the internal environment of the stirring barrel 1 conforms to the humus of the "Organic Fertilizer" (NY / T 525-2021) standard, realizing the directional conversion of waste to organic fertilizer.

[0041] The food waste microorganism degradation treatment process is as follows:

[0042] First, pour the food waste into a biological substance sorting machine. The biological substance sorting machine removes non-organic substances such as plastic bags and bottles from the food waste and centrally collects the organic matter.

[0043] Second, pour the organic matter into a crusher to crush the large pieces of materials to a particle size of 2-5 cm.

[0044] Third, wash the crushed materials with high-pressure water to remove grease, salt and attached pollutants.

[0045] IV. Transport the materials and microorganisms in the corresponding proportions to the stirring tank 1, stir and supply oxygen through the electric stirrer 2, and maintain the internal temperature of the stirring tank 1 at the maintenance temperature of 40-50 °C through the electric heater, extend the semi-rotted stage, and reduce the loss of volatile nutrients such as nitrogen and potassium;

[0046] V. When the materials are fermented into wet fertilizer, the electric plate valve can be opened to discharge the wet fertilizer through the discharge pipe. The wet fertilizer can be directly used as the base fertilizer for water-retaining crops or mixed with dry soil to improve the compacted soil;

[0047] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 shown, a transmission cavity communicating with the guiding cavity 11 is formed inside the stirring tank 1. The electric lifting assembly 41 includes a servo motor, a protective box and a belt. The output shaft of the servo motor is fixedly connected with a threaded column. A threaded plate fixedly connected with the closed pipe 42 is threadedly connected to the surface of the threaded column. The driving motor 44 and the pH value detector 43 are both fixedly connected to the top of the threaded plate. An installation cavity is formed inside the threaded plate. Two spur gears 46 are both arranged inside the installation cavity. The protective box is fixedly connected to the side end of the stirring tank 1. The top of the threaded column penetrates out of the protective box. A first pulley is fixedly connected to the surface of the threaded column. A second pulley is rotatably connected inside the transmission cavity. The first pulley and the second pulley are connected by a belt in a transmission manner. An annular scraping plate contacting the closed pipe 42 is fixedly connected to the inner side of the second pulley;

[0048] When the electric lifting assembly 41 is in use, the servo motor drives the threaded column to rotate. The threaded column drives the threaded plate to lift through rotation. The threaded plate drives the closed pipe 42 to lift and lower along the guiding cavity 11. At the same time, the threaded plate also drives the pH value detector 43 and the driving motor 44 to lift and lower. The pH value detector 43 drives the detection probe 45 to lift and lower together through the electrical rotary joint 410. At the same time, the threaded column drives the first pulley to rotate. The first pulley drives the second pulley to rotate through the belt. The second pulley drives the annular scraping plate to rotate to scrape off the impurities adhering to the surface of the passing closed pipe 42. This can not only keep the local part of the passing closed pipe 42 always clean, but also use the rotational centrifugal force to throw off the scraped impurities to ensure that the annular scraping plate can effectively scrape off the impurities.

[0049] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the pH value monitoring mechanism 4 also includes a cleaning component, which includes a liquid conducting box, both ends of the top and bottom of the liquid conducting box are provided with circular holes, the bottom of the closed tube 42 passes through the upper circular hole and the lower circular hole in sequence, and the liquid conducting port 48 is arranged inside the liquid conducting box when it rises to the highest point, one end of the liquid conducting box is fixedly connected and connected with a drain pipe, the other end of the liquid conducting box is fixedly connected with a liquid conducting bucket fitted with the closed tube 42, the opening of the liquid conducting bucket is connected with the liquid conducting port 48, the other end of the liquid conducting bucket passes through the liquid conducting box, the other end of the liquid conducting bucket is fixedly connected and connected with an infusion pump, the liquid inlet end of the infusion pump is fixedly connected and connected with a liquid storage tank, and the interior of the liquid storage tank is filled with cleaning liquid;

[0050] When the closed tube 42 rises to the highest point, the staff can operate the controller 3 to start the infusion pump, and the infusion pump will transport the cleaning liquid into the liquid guide bucket toward the inside of the liquid storage tank. The cleaning liquid will clean the detection end of the detection probe 45 through the liquid guide bucket, the outer liquid guide port 48 and the inner liquid guide port 48 in turn, which can wash away the liquid materials, dirt and other interferences adhered to the detection end of the detection probe 45. This can not only reduce the probability of interferences solidifying or corroding the detection probe 45, so as to improve the accuracy of subsequent detection of the detection probe 45, but also ensure the effectiveness of the subsequent calibration of the pH value detector 43, and further improve the accuracy of subsequent detection of the detection probe 45.

[0051] Working principle: before the detection probe 45 detects the liquid material at the corresponding depth, the staff operates the controller 3 to control the drive motor 44 to drive the spur gear 46 connected thereto to rotate ninety degrees, the spur gear 46 drives another spur gear 46 to rotate ninety degrees in the opposite direction, and the other spur gear 46 drives the detection probe 45 and the blocking cylinder 47 to rotate ninety degrees. At this time, the blocking cylinder 47 drives the inner liquid guide port 48 and the outer liquid guide port 48 to be staggered to achieve the effect of blocking the liquid material from contacting the detection probe 45, and then the staff operates the controller 3 to control the electric lifting assembly 41 to move the closed tube 42 and the detection probe 45 down to the corresponding depth, and then the staff operates the controller 3 to control the drive motor 44 to reset, and the drive motor 44 drives the detection probe through the two spur gears 46 45 and the blocking cylinder 47 are reset, and the blocking cylinder 47 drives the inner liquid guiding port 48 to be connected with the outer liquid guiding port 48, so that the liquid material passes through the outer liquid guiding port 48 and the inner liquid guiding port 48 in turn and contacts with the detection probe 45, and the pH value detector 43 can normally detect the pH value of the liquid material at the corresponding depth through the detection probe 45. This not only enables the detection probe 45 to be placed above the kitchen waste when the electric stirrer 2 is running, avoiding the garbage from being entangled and wrapped around the surface of the closed tube 42 during the stirring process, thereby reducing the interference with the detection of the detection probe 45, but also the staff can move the detection probe 45 down to the corresponding depth for detection, which can detect the pH value of liquid materials at different depths, thereby improving the accuracy of monitoring the fermentation stage of kitchen waste.

[0052] It should be noted that in the above description, the electric stirrer 2, the controller 3, the pH detector 43, the drive motor 44, the detection probe 45, the electrical rotary joint 410, the electric heater, the temperature sensor, the electrochemical sensor, the humidity sensor, the biological substance separator, the crusher, the vertical dehydrator, the electric plate valve, the servo motor, the infusion pump, and the cleaning liquid are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply for the electric stirrer 2, the controller 3, the pH detector 43, the drive motor 44, the electric heater, the temperature sensor, the electrochemical sensor, the humidity sensor, the biological substance separator, the crusher, the vertical dehydrator, the electric plate valve, the servo motor, and the infusion pump can be powered by an internal power supply or by the mains power supply. The specific power supply method can be selected according to the situation and will not be elaborated here.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0054] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
