Description

Technical Field

[0001] This utility model belongs to the technical field of public health and toilet facilities, specifically relating to the field of microbial application technology and biological treatment engineering, and particularly to a multi-point mobile toilet microbial fermentation chamber. Background Technology

[0002] In the field of public health and toilet facilities, microbial fermentation chambers are the core equipment for treating feces. They degrade feces into harmless substances through microbial metabolism and are widely used in rural dry toilet renovation, scenic area mobile toilets, temporary mobile toilets and other scenarios.

[0003] In existing technologies, toilet facilities with multiple stalls typically adopt a "one-stall-one-station" model, meaning each stall corresponds to an independent microbial fermentation tank. This model has the following significant drawbacks: 1. Low space utilization: Each independent fermentation chamber requires a separate installation space. In scenarios with limited space, such as rural homes and small public toilets, the arrangement of multiple independent chambers can lead to space congestion and may even fail to meet installation requirements. 2. High equipment cost: Each independent fermentation chamber requires a separate chamber body, ventilation system, stirring device and automatic control system. The repeated hardware investment greatly increases the overall manufacturing and installation cost of the equipment. 3. High difficulty in operation and maintenance: Multiple independent compartments require separate addition of microbial communities, temperature / humidity control, and sludge cleaning and maintenance, which not only increases manpower input, but also easily leads to fluctuations in microbial activity due to inconsistent parameter control of each compartment (such as excessively high temperature in some compartments and insufficient humidity in some compartments), thereby reducing the efficiency of fecal treatment. 4. High risk of secondary pollution: The exhaust gases (such as ammonia and hydrogen sulfide) from multiple independent chambers are emitted in a dispersed manner, and it is difficult for the deodorization treatment of each chamber to meet the standards at the same time, which can easily cause the spread of odors and affect the surrounding environment; 5. Poor scene adaptability: The independent compartments cannot be flexibly adjusted according to the number of toilets, and most are fixed installations, which cannot meet the needs of "moving on demand" in scenic spots, temporary events and other scenarios.

[0004] Therefore, in order to solve the above-mentioned technical problems, the technical solution of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing "one-compartment-per-room" microbial fermentation chambers in multi-toilet scenarios, such as low space utilization, high equipment cost, high maintenance difficulty, and high risk of secondary pollution. It provides a multi-point mobile toilet microbial fermentation chamber that can "adapt to multiple toilets with the same chamber", improve space utilization and fecal treatment efficiency, reduce equipment cost and maintenance difficulty, reduce secondary pollution, and has flexible mobility and intelligent control functions, making it suitable for diverse scenarios such as rural dry toilet renovation, scenic area mobile toilets, and temporary mobile toilets.

[0006] The technical solution adopted in this utility model is as follows: A multi-point mobile toilet microbial fermentation chamber The silo structure is made of 304 stainless steel and is horizontally set up. The inner wall of the silo forms a space to hold feces and urine. The top of the silo is equipped with several receiving ports that correspond one-to-one with the toilet pits. The bottom side is equipped with a discharge port. The top is also equipped with several ventilation mechanisms that are staggered with the receiving ports to ensure uniform ventilation and not interfere with the feeding. Stirring mechanism: Two parallel stirring shafts are installed at both ends of the middle of the chamber. The two ends of the stirring shafts are rotatably connected to the chamber. Each stirring shaft has several stirring structures along its length. The stirring structures of the two stirring shafts form several sets of staggered stirring mechanisms to improve the uniformity of stirring. Each stirring shaft is equipped with a transmission gear at one end. A rotatable transmission shaft is installed on the chamber. One end of the transmission shaft is connected to a drive structure, and the other end is equipped with a drive gear. The drive gear is located between two transmission gears and meshes with them to realize the synchronous and opposite rotation of the two stirring shafts. Mobile structure: The four corners of the bottom of the compartment are equipped with rolling structures to facilitate overall movement and adapt to temporary scenario requirements; Intelligent control: The silo is equipped with a PLC intelligent control system, which is electrically connected to the drive structure, ventilation mechanism, temperature sensor, humidity sensor and automatic discharge device to achieve precise control of fermentation temperature, humidity and stirring speed, as well as intelligent self-diagnosis of faults. Auxiliary components: The exhaust duct of the ventilation system is equipped with a deodorization device to reduce exhaust gas pollution; a wire trough is provided at one end of the silo to organize the wires; the automatic discharge device includes a discharge valve and a conveying screw to realize the automatic discharge of degradation products.

[0007] The automatic discharge device includes a discharge valve and a conveying screw. The discharge valve is fixedly installed at the discharge port and its inlet end is connected to the accommodating space of the silo. The discharge end of the discharge valve is fixedly connected to the inlet end of the conveying screw. The housing of the conveying screw is fixedly connected to the outer wall of the bottom of the silo. The discharge valve and the conveying screw are electrically connected to the PLC intelligent control system. The PLC intelligent control system can control the opening and closing of the discharge valve and the start and stop of the conveying screw.

[0008] Working principle Installation and positioning: Move the device to the target location (such as a rural family courtyard or a scenic viewing platform) using the rolling structure at the bottom of the silo, activate the braking device on the rolling wheels to fix the silo; connect the top of each material receiving pipe to the bottom of the corresponding toilet pit to complete the construction of the material feeding channel; Feeding and Degradation: Feces and urine enter the silo through the receiving pipe; the PLC intelligent control system starts the drive structure, the drive motor drives the transmission shaft to rotate through the reducer, the drive gear on the transmission shaft drives two transmission gears to rotate in opposite directions, thereby causing the two stirring shafts to rotate synchronously in opposite directions. The stirring structure and crushing blades stir and crush the material, so that the material and microorganisms can fully contact each other; at the same time, the ventilation mechanism starts, the blower draws air from the silo through the air inlet pipe, and the exhaust gas is discharged after being treated by the deodorization device in the air outlet pipe. Parameter control: Temperature and humidity sensors monitor the fermentation temperature and humidity inside the chamber in real time and transmit the signals to the PLC intelligent control system. If the temperature is lower than the preset value (35-42℃), the PLC can control the external heating components (such as electric heating elements) to raise the temperature. If the humidity is lower than the preset value (60-67%), the PLC can control the external humidification components to replenish water. If the parameters exceed the standard, the PLC will adjust the ventilation volume or stirring speed in time to ensure the optimal environment for microbial metabolism. Automatic discharge: When the amount of degradation products in the silo reaches the preset amount (detected by the material level sensor on the side wall of the silo, which is electrically connected to the PLC), the PLC controls the discharge valve of the automatic discharge device to open and starts the conveying screw to transport the degradation products (such as organic fertilizer semi-finished products) to the designated collection device. After the discharge is completed, the PLC controls the discharge valve to close and the conveying screw to stop. Fault self-diagnosis: The PLC intelligent control system monitors the operating current and status of the drive motor, blower, discharge valve, and conveying screw in real time. If faults such as motor overload or valve jamming occur, the system will immediately issue an alarm signal (such as an audible and visual alarm) and record the fault type to facilitate quick repair by maintenance personnel.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. A multi-point mobile toilet microbial fermentation chamber with high space utilization. The same chamber has multiple material receiving ports and can be adapted to 2-6 toilets. There is no need to configure a separate chamber for each toilet. Compared with the traditional "one chamber per toilet" mode, the overall footprint of the equipment is reduced by 40%-50%, which is especially suitable for rural families, small public toilets and other scenarios with limited space. 2. The processing efficiency of this utility model is improved; multi-point feeding can maintain a stable concentration of organic matter in the silo, avoiding fluctuations in microbial activity caused by "sudden increase in load" or "long-term vacancy"; the PLC intelligent control system precisely regulates temperature and humidity, and with the staggered stirring mechanism, the material and microorganisms are in full contact, shortening the fecal degradation cycle by 30%-40%, and the microorganisms are always in a highly efficient metabolic state. 3. The cost of this utility model is significantly reduced; by sharing the silo structure, ventilation system, stirring device and PLC control system, the repeated investment in hardware is reduced by more than 50%, and the equipment manufacturing and installation costs are reduced by 35%-45%; during operation and maintenance, only one addition of bacterial agent and one set of system monitoring parameters are required, reducing manpower input by 60% and significantly reducing operation and maintenance costs; 4. This utility model reduces secondary pollution; the ventilation mechanism centrally extracts the waste gas in the chamber, and discharges it after treatment by the deodorization device (such as activated carbon deodorization device or biological filter deodorization device) in the exhaust duct. The removal rate of ammonia and hydrogen sulfide is over 95%, avoiding the problem of incomplete deodorization caused by decentralized exhaust. 5. This utility model has strong adaptability to various scenarios; the number of receiving ports can be adjusted according to needs (2-3 ports are suitable for families, 4-6 ports are suitable for small public toilets / scenic toilets), the standardized container body is convenient for mass production and modular installation; the rolling structure combined with the braking device can be moved and fixed flexibly, and is suitable for scenarios such as rural dry toilet renovation, scenic mobile toilets, and temporary mobile toilets.
