Description
Technical Field
[0001] This utility model belongs to the field of fecal degradation technology, specifically relating to a microbial degradation device that can achieve integrated degradation of human excrement and urine. Background Technology
[0002] With societal development, on-site degradation technology has also evolved, emerging as a new wastewater treatment technology in recent years. It utilizes microorganisms and auxiliary devices to degrade feces on-site, achieving pollution-free and discharge-free results. Currently, fecal degradation devices typically place feces into a degradation chamber containing microorganisms for degradation. The degraded feces can then be used as fertilizer in agricultural production. In existing technologies, the decomposition of feces by microorganisms takes place in a degradation tank. After the tank is filled, the material inside is manually stirred, and the degradation temperature is controlled based on the operator's experience to ensure degradation effectiveness and efficiency. However, due to limitations in labor costs and experience, the following problems often arise during the actual degradation process: microorganisms and feces cannot be fully mixed, the activity of microorganisms in the degradation tank cannot be guaranteed, resulting in low degradation efficiency and unsatisfactory degradation effects. Summary of the Invention
[0003] In view of the problems existing in the prior art, the present invention provides a microbial degradation device that can realize the integrated degradation of human excrement and urine. The device has a simple structure and low investment cost. It can control the degradation process in a relatively automated manner, promote the full mixing of microorganisms and feces, and at the same time ensure the reduction of microbial activity in the tank, which can significantly improve the degradation efficiency and effect.
[0004] To achieve the above objectives, this utility model provides a microbial degradation device capable of integrated degradation of human excrement and urine, comprising a support box, a degradation tank, a heating plate, a stirring shaft, a geared motor, a temperature sensor, a humidity sensor, a collection tank, a foot pedal, and a controller.
[0005] The supporting box has a degradation tank receiving cavity; the degradation tank is fixedly installed in the degradation tank receiving cavity, and its interior forms a degradation chamber;
[0006] The heating plate is fitted to the periphery of the bottom of the degradation tank and is used to heat the degradation chamber;
[0007] Two stirring shafts are arranged side by side inside the degradation chamber, and stirring blades are installed on their respective shafts; both stirring shafts are rotatably connected to the degradation tank, and one end of each shaft on the same side can be rotatably extended to the outside of the degradation tank, and respectively connected to the driving wheel and the driven wheel located on the outside of the degradation tank; the driving wheel and the driven wheel are connected by a belt.
[0008] The geared motor is installed in the bearing housing and located outside the drive wheel. The geared motor is connected to a stirring shaft where the drive wheel is located.
[0009] The temperature sensor and humidity sensor are both installed inside the degradation chamber, and are used to collect the temperature signal and humidity signal of the degradation chamber, respectively.
[0010] The collection tank surrounds the outer periphery of the degradation tank, and the bottom of its inner cavity is connected to the degradation chamber through overflow holes opened on the side wall of the degradation tank. At the same time, each overflow hole is equipped with a filter screen; the collection tank is connected to an output pipeline that communicates with its inner cavity.
[0011] The foot pedal is an automatic reset foot pedal assembly, which is installed around the top of the degradation tank at the top of the support box; a contact switch is provided at the bottom of the foot pedal, which is used to send an electrical signal that someone is present after the foot pedal is stepped on.
[0012] The controller is installed in the housing and is connected to the temperature sensor, humidity sensor, contact switch, heating plate and geared motor respectively.
[0013] Furthermore, in order to utilize the fan to create a pressure difference between the inside and outside of the chamber, thereby efficiently exhausting the odors generated in the degradation chamber, a fan is also included. The fan is installed on the top of the support box, and its air outlet faces the top of the lowered chamber.
[0014] Furthermore, to prevent auxiliary materials from entering the collection tank from the overflow hole, the filter screen has a double-layer structure.
[0015] As a preferred embodiment, the degradation chamber in the degradation tank is lined with biological strains and excipients to promote degradation.
[0016] As a preferred embodiment, the device also includes a power supply module for supplying power to the various electrical devices.
[0017] As a preferred embodiment, the controller is a PLC controller.
[0018] In this invention, a heating plate is installed around the bottom of the degradation tank, facilitating heating of the tank and thus enabling control of the degradation temperature. Two stirring shafts are installed within the degradation chamber, each equipped with a stirring blade. This facilitates stirring of the material within the chamber, promoting thorough mixing of the microorganisms and excrement, accelerating degradation efficiency, and significantly improving the degradation effect. A geared motor drives one stirring shaft, while a belt connects the driving and driven pulleys mounted on the two shafts. This allows a single geared motor to simultaneously drive both shafts and blades, improving stirring efficiency while reducing input costs. By installing temperature and humidity sensors in the degradation chamber, real-time temperature and humidity signals can be easily collected. The controller can then obtain temperature and humidity data and use this data to control the heating plate power in a closed-loop manner. This maintains the material to be degraded within a suitable temperature range, ensuring optimal activity of the microorganisms and auxiliary materials, thus guaranteeing the efficiency and effectiveness of fecal degradation. A collection tank is installed outside the degradation tank, connected to an output pipe. An overflow hole is located on the side wall of the degradation tank, allowing excess urine to be drained from the degradation chamber. This facilitates the removal of excess urine, further ensuring the degradation effect and efficiency. The foot pedal and contact switch design facilitate the detection of presence on the outside of the degradation tank. When someone is present and steps on the foot pedal, the contact switch sends a presence signal to the controller. Upon receiving this signal, the controller stops the geared motor to prevent discomfort caused by unpleasant odors generated during stirring. When the presence signal disappears, the controller restarts the geared motor, thus enabling a user-friendly control process where stirring stops when no one is present and stops when someone is present. This device features a simple structure and low investment cost. It provides relatively automated control of the degradation process, promoting thorough mixing of microorganisms and feces while minimizing microbial activity within the tank, significantly improving degradation efficiency and effectiveness.
