Description

[0001] This application is a divisional application. The original application number is 202410564607.6, the application date is May 9, 2024, and the invention title is "Waterless Self-Cleaning Toilet in Underground Mines". Technical Field

[0002] This invention relates to the field of waterless toilet technology, and in particular to a waterless self-cleaning toilet. Background Technology

[0003] Due to limited conditions, cramped spaces, and poor air circulation, sanitation facilities have always been a challenge in underground mines.

[0004] Water-flushing toilets and simple packaged toilets, due to the mixing of feces and urine, undergo anaerobic reactions, generating flammable, explosive, foul-smelling, and toxic gases such as biogas, hydrogen sulfide, and skatole. These do not comply with mine safety management regulations, require frequent external transportation, are inconvenient to use, provide a poor user experience, and are difficult to apply in underground mines. Patent CN201414748Y discloses a waterless toilet, including a toilet seat with a lid at the top and a main body at the bottom. A ring-shaped seat cushion is located between the lid and the main body. A removable latrine is located under the toilet seat. The waterless toilet also includes a hot air blower whose air inlet is connected to the atmosphere via a one-way valve and whose air outlet is connected to the toilet seat via an air inlet slot in the main body; a dehumidifier whose air inlet is connected to the moisture outlet of the latrine and whose drain pipe is connected to the atmosphere outside the toilet; and a heater located under the latrine and synchronized with the dehumidifier. The above-mentioned solutions do not have a device for separating feces and urine. Even if there is a dehumidification device, anaerobic reactions are likely to occur. Furthermore, the feces are only dried and cannot be degraded. The frequency of replacing the feces basin is high, which is not convenient for use in mines. Summary of the Invention

When the bioreactor chamber is being fed, both the first and second stirring shafts rotate clockwise; when the bioreactor chamber is discharging slag, both the first and second stirring shafts rotate counterclockwise, achieving slag discharge and feeding from a single inlet, thus solving the problem of... The issue of the feed inlet being located only in one corner of the bioreactor chamber; when the first and second stirring shafts rotate in opposite directions, the microbial packing material circulates within the bioreactor chamber, achieving uniform mixing and improving fecal decomposition efficiency; when the human body sensor detects a person, the PLC control board issues a command to turn on the negative pressure fan, activate the fresh air mechanism, and purify odors; when the odor sensor detects excessive odor, the negative pressure fan turns on, the fresh air mechanism activates, and purifies the air; when the carbon dioxide concentration exceeds the standard, the negative pressure fan turns on to achieve air circulation; when the temperature sensor detects a temperature below the low-temperature threshold, the PLC control board issues a command to turn on the temperature compensator for temperature compensation; when the temperature sensor detects a temperature above the first high-temperature threshold, the temperature compensator stops; when the temperature sensor detects a temperature above the second high-temperature threshold, the negative pressure fan starts to exhaust hot and humid air; when the humidity sensor detects humidity above the humidity threshold, the temperature compensator starts, the first and second stirring shafts start, and the negative pressure fan starts for dehumidification; the fault sensor indicates a fault and prompts the third and fourth explosion-proof motors for maintenance.

An observation port 61 is located on the left side of the top of the solid-liquid separation toilet bowl 6, and a toilet opening 62 is located on the right side. An observation plate is detachably connected to the observation port 61. A sliding plate 63, adapted to the toilet opening 62, is slidably mounted between the front and rear inner walls of the solid-liquid separation toilet bowl 6. A valve scraper 65, adapted to the sliding plate 63, is rotatably mounted on the left side wall of the toilet opening 62 via a rotating shaft 661. The valve scraper 65, the sliding plate 63, the front wall of the toilet opening 62, and the toilet opening 62 are all connected. The rear side wall and the right side wall of the toilet opening 62 form a toilet trough. The solid-liquid separation toilet cleaner 6 has a first explosion-proof motor 64 on the right side, which is used to drive the sliding plate 63 to slide. The solid-liquid separation toilet cleaner 6 has a second explosion-proof motor 66 on the rear left side. The second explosion-proof motor 66 is connected to the rotating shaft 661 through a linkage mechanism, which is used to drive the valve scraper 65 to rotate. The solid-liquid separation toilet cleaner 6 has a urine collection chamber 67 on the rear right side. The sliding plate 63 is inclined towards the rear side wall of the toilet opening 62. The rear side wall of the toilet opening 62 has a drain hole 631, which is used to connect the toilet trough and the urine collection chamber 67.

[0042] In this embodiment, after the user uses the toilet, urine flows along the inclined slide plate 63 from the drain hole 631 into the urine collection chamber 67 and is stored in the grey water tank 4. When cleaning the feces, firstly, the second explosion-proof motor 66 drives the valve scraper 65 to rotate towards the observation port 61, and the first explosion-proof motor 64 drives the slide plate 63 to slide towards the observation port 61. Then, the second explosion-proof motor 66 drives the valve scraper 65 to rotate away from the observation port 61, and the first explosion-proof motor 64 drives the slide plate 63 to slide away from the observation port 61.

The second drive gear 99 is connected to the motor gear at the output end of the fourth explosion-proof motor 96 via a second transmission chain 98. The first stirring shaft 93 and the second stirring shaft are symmetrically arranged.

[0047] Multiple first stirring rods 931 are staggered on the extension end of the first stirring shaft 93, with an angle of 90° between adjacent first stirring rods 931. Each first stirring rod 931 is provided with a first stirring blade 932, with an angle of 45° between the first stirring blade 932 and the axis of the first stirring rod 931.

[0052] An inspection port 12 is provided at the bottom of the right side wall of the building 1 for easy maintenance.

[0053] In this embodiment, when the human body sensor 23 detects a person, the PLC control board 81 issues a command to turn on the negative pressure fan 73, activate the fresh air mechanism 7, and purify odors. When the odor sensor 53 detects excessive odor, the negative pressure fan 73 turns on, the fresh air mechanism 7 activates, and purifies the air. When the carbon dioxide concentration exceeds the standard, the negative pressure fan 73 turns on to achieve air circulation. When the temperature sensor 51 detects that the temperature is below the low temperature threshold, the PLC control board 81 issues a command to turn on the temperature compensator to perform temperature compensation. When the temperature sensor 51 detects that the temperature is above the first high temperature threshold, the temperature compensator stops. When the temperature sensor 51 detects that the temperature is above the second high temperature threshold, the negative pressure fan 73 starts to exhaust hot and humid air. When the humidity sensor 52 detects that the humidity is above the humidity threshold, the temperature compensator starts, the first stirring shaft 93 and the second stirring shaft start, and the negative pressure fan 73 starts to perform dehumidification. The fault sensor indicates a fault and prompts the third explosion-proof motor 92 and the fourth explosion-proof motor 96 for maintenance.
