Description

Technical Field

[0001] The invention belongs to the technical field of public health equipment, and in particular relates to a temporary toilet at a construction site and a use method thereof. Background Art

[0002] Public toilets bring convenience to people's daily lives, reduce urban pollution, and ensure urban hygiene. However, in the construction process of buildings, roads, and railways, public toilets are often not built on the construction site at the beginning. There are a large number of workers, and it is very common for them to urinate and defecate anywhere, which affects the hygiene of the construction site and brings health hazards. The establishment of traditional construction site toilets requires a certain amount of time and construction costs, and they cannot be moved. After the construction site is completed, they are dismantled, resulting in waste and cannot be used flexibly. At the same time, the construction site also needs to be connected to a water source. In some special environment sites such as water shortages, it takes a long time to connect to the water source, and it is difficult to ensure the normal use of the construction site toilets during this period. In addition, traditional toilets consume a lot of clean water for flushing, resulting in a waste of water resources. Especially in water-scarce construction sites, the disadvantages of traditional toilets wasting water are obvious. Summary of the invention

[0015] How to use the temporary toilets on the construction site described above:

[0016] Preparation: Use the walking wheels to pull the temporary toilet to the construction site where it is inconvenient to use the toilet and lock the walking wheels; fill the clean water tank with water;

[0017] Toilet use: The user enters the toilet and uses the squat toilet. When flushing, the water in the clean water tank is pumped into the squat toilet through the clean water flushing pipe by the clean water pump to flush the stool. The sewage after flushing the stool enters the centrifugal barrel of the solid-liquid separation chamber. The motor drives the centrifugal barrel to rotate, and the liquid is thrown out from the water-throwing hole by centrifugal force into the liquid-throwing chamber, and the solid remains in the centrifugal barrel. The liquid entering the liquid-throwing chamber passes through the filter component and enters the sewage tank seat from the bottom of the liquid-throwing chamber for storage;

[0018] Sewage utilization: When there is sewage in the sewage tank, the sewage pump starts first when the flush switch is pressed, and the sewage in the sewage tank is pumped into the squat toilet through the sewage flushing pipe to flush the feces in the squat toilet; due to the existence of the time relay, the clean water flushing pipe is turned on after a delay, and clean water is pumped from the clean water tank into the squat toilet for another flush, reducing odor;

[0019] Cleaning work: When the solid feces and urine in the sewage tank seat or the solid-liquid separation bin is full, the staff can pull out the solid-liquid separation bin by the handle; at this time, under the action of the roller, the solid-liquid separation bin can be easily pulled out; then the feces and urine in the centrifugal barrel are collected and cleaned, and the entire solid-liquid separation bin is disinfected again, and finally it can be put back into the concave space; or the cleaned solid-liquid separation bin can be replaced and then the pulled-out solid-liquid separation bin can be cleaned; the water in the sewage tank seat can be discharged into the sewage pipe through the drain pipe, or collected and treated in a container, or connected to a sewage suction truck for discharge.

[0020] The technical solution of the present invention has the following beneficial effects:

[0021] 1. The present invention provides a clean water tank and a sewage tank seat, so that when flushing the squat toilet after defecation, the sewage in the sewage tank seat can be firstly drawn to flush the feces and urine, and then the clean water in the clean water tank is drawn to flush and eliminate the odor, thereby reducing the amount of clean water used, saving water, and reducing the number of water replenishment times, which is beneficial to the use of construction sites with water shortage.

[0022] 2. The present invention makes the entire device easy to move by using walking wheels. The entire temporary toilet device is flexible to use and can be used at the beginning of its establishment on the construction site without waiting for the establishment of a public toilet, thus saving time and cost in building toilets, preventing workers from urinating and defecating anywhere, and improving the construction site environment. At the same time, it can be moved to a suitable position during the construction process and can be moved to another construction site for use after the construction is completed, thus saving costs and having a wide range of applications.

[0023] 3. The solid-liquid separation bin of the present invention can be dismantled and cleaned, ensuring that the temporary toilet can be used for a long time and is simple and convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS
