Description

Technical Field

[0001] The present invention relates to the field of rural sewage treatment, and in particular to a feces and urine source separation toilet collection device and a source separation method thereof. Background Art

[0002] At present, as the lifestyle of rural residents in my country becomes more and more urbanized, the daily per capita water consumption and domestic sewage volume in rural areas have also increased dramatically. According to the water quality, rural domestic sewage can be divided into two categories: gray water and black water. Gray water comes from washing and bathing water in the kitchen and bathroom, and black water is composed of feces (including toilet paper), urine and flushing water. The volume of gray water is large, accounting for 50-80% of rural domestic sewage, but the concentration of pollutants is low and easy to treat; the volume of black water is small, but the concentration of pollutants is high and difficult to treat. If gray water and black water are mixed for treatment, the overall water volume is large and difficult to treat. In addition, feces and urine contain a large amount of nitrogen, phosphorus and potassium, which are all organic nutrients necessary for the growth of crops. The mixing of gray water and black water will result in a large amount of organic nutrients that cannot be applied to farmland.

[0003] Based on the existence of organic matter with high utilization value in black water, European and North American scholars proposed source separation technology at the end of the last century, that is, collecting high-concentration feces and urine separately with as little dilution as possible. my country's traditional dry toilets can collect high-concentration feces and urine very well, but it is difficult to transfer the feces out, and the sanitary conditions are extremely poor, especially in summer, when flies, mosquitoes, etc. are rampant and the smell is everywhere. Although the flush toilets sold on the market can improve the environmental problems caused by dry toilets, the flushing water will dilute the feces and urine hundreds of times. Not only can the feces and urine not be efficiently utilized, but it also causes water pollution. Therefore, it is necessary to provide a new type of toilet collector to achieve feces and urine source separation, and this method can not only retain the advantages of flush toilets and dry toilets, but also abandon the disadvantages of both. Summary of the invention

[0004] The purpose of the present invention is to provide a feces and urine source separation toilet, which can separate the feces and flushing water, not only saving water and improving the toilet environment, but also reducing the dilution effect of flushing water on the feces, thereby reducing the amount of sewage treatment, reducing the concentration of sewage pollutants, and improving the fertilizer efficiency of the feces.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a feces and urine source separation toilet, including a toilet bowl and a flushing device arranged in cooperation with the toilet bowl, characterized in that a baffle is arranged in the toilet bowl, a urinal trough and a feces trough are arranged before and after the baffle, and water outlets cooperating with the flushing device are arranged above the urinal trough and the feces trough, a urine discharge pipe is arranged below the urinal trough, and the urine discharge pipe is connected with the feces collection device, a flat valve and a flat valve slide cooperating with the flat valve are arranged below the feces trough, a feces collection device is arranged below the flat valve, a water seal space is reserved above the flat valve, and a drainage pipe is arranged on the side of the water seal space.

[0006] Furthermore, the feces collection device includes a urine collection pool and a feces collection pool, the urination tube is connected to the urine collection pool, the feces collection pool is arranged below the flat valve, or a feces transmission device is arranged below the flat valve, and the feces transmission device is connected to the feces collection pool.

[0007] Furthermore, an airbag plug is connected below the flat valve, and the airbag plug is connected to the vacuum pump and the air pump respectively.

[0008] Furthermore, the toilet is a sitting toilet or a squatting toilet, and a cover plate is arranged above the sitting toilet.

[0009] Furthermore, the feces collecting devices are respectively provided with exhaust ports.

[0010] Furthermore, the flushing device is provided with a flushing button, a water inlet pipe, a water supply pipe, an overflow pipe, and a flushing pipe.

[0011] Furthermore, the toilet collector includes an intelligent panel, which is respectively connected to the vacuum pump, the air pump and the stool conveying device so as to control the actions of the vacuum pump, the air pump and the stool conveying device. After using the toilet, the vacuum pump starts, the air bag plug gradually shrinks and drives the flat valve to open; after 2 to 3 seconds, the vacuum pump is turned off, the air pump is started, the air bag plug gradually opens and drives the flat valve to close; after 2 to 3 seconds, the air pump is turned off; when the flat valve is opened, the intelligent panel controls the stool conveying device to start and closes after 8 to 10 seconds.

[0012] Another object of the present invention is to provide a source separation method of a feces and urine source separation toilet collector, which separates feces and urine through a feces and urine source separation toilet collector. The method can separate feces and flushing water, which not only saves water and improves the toilet environment, but also reduces the dilution effect of flushing water on feces, thereby reducing the amount of sewage treatment, reducing the concentration of sewage pollutants, and improving the fertilizer efficiency of feces.

[0013] In order to achieve the above object, the present invention is implemented by the following technical scheme: a source separation method for a feces and urine source separation toilet, characterized in that the method comprises the following steps:

[0014] When using the toilet, urine falls into the urinal trough in the toilet and is collected into the urine collection pool through the urination tube, while feces fall into the flat valve under the feces trough;

[0015] After using the toilet, the vacuum pump starts, the airbag plug located under the flat valve gradually shrinks and drives the flat valve to open, scraping the feces that fall on the flat valve, and the scraped feces fall to the feces conveying device under the flat valve; at the same time, the feces conveying device starts to send the feces to the feces collection pool;

[0016] The vacuum pump is turned off, the air pump is started, the airbag plug is gradually opened and drives the flat valve to close; the air pump is turned off after 2~3s;

[0017] The stool conveying device stops;

[0018] Press the flush button. When you need to urinate, press the pee button. The flushing device will flush the urinal, and the flushing water will enter the stool collection device through the urine tube. When you need to defecate, press the defecation button. The flushing device will flush the defecation trough, and the flushing water will be discharged through the drain pipe on the side above the flat valve.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The toilet device of the present invention is provided with a baffle to separate defecation and urination. The flushing water volume after urination is less than that during defecation, and the overall water volume is reduced compared with the traditional flush toilet; and the toilet device is also provided with a flat valve. When the toilet is finished, the flat valve is opened, and most of the feces enter the feces conveying device. Then the flat valve is closed, and the flushing device only needs to flush the remaining feces, thereby further saving water;

[0021] 2. The present invention collects the flushing water from the toilet to form a water seal, improves the toilet environment, and avoids the problems of stench, mosquitoes and flies caused by dry toilets. Therefore, the advantages of flush toilets are retained and the disadvantages of dry toilets are eliminated.

[0022] 3. The present invention adopts a feces collection device to collect feces, which is convenient for use as fertilizer for crops, thus retaining the advantages of dry toilets and eliminating the disadvantages of flush toilets;

[0023] 4. The present invention realizes the separation of stool and flushing water, reduces the dilution effect of flushing water on stool, thereby reducing the amount of sewage treatment, reducing the concentration of sewage pollutants, and improving the fertilizer effect of stool.

DETAILED DESCRIPTION

[0027] The present invention is further described with reference to the accompanying drawings and examples: Figure 1 As shown, a source separation toilet is composed of a toilet seat device 1, a stool conveying device 2, a urine collecting device 3, a stool collecting device 4 and a flushing device 5.

[0028] A feces conveying device 2, a urine collecting device 3, and a feces collecting device 4 are installed under the toilet device 1, wherein the presence of the feces conveying device 2 allows the position of the feces collecting device 4 to be unrestricted and does not have to be installed directly under the feces trough. If the feces collecting device can be conveniently arranged under the feces trough, the feces conveying device can be cancelled.

[0029] In order to avoid the environmental problems caused by dry toilets, a flushing device 5 is installed on the toilet device 1. The toilet device includes a cover plate 6 and a toilet bowl 7. Of course, the toilet bowl can also be replaced by a squat toilet.

[0030] A baffle 8 is provided in the toilet bowl, and a urinal trough 9 and a feces trough 10 are provided before and after the baffle, in order to collect feces and urine separately on the one hand, and to use different water amounts when flushing on the other hand, thereby saving water.

[0031] A urine discharge pipe 11 is provided below the urinal, and urine and a small amount of flushing water are discharged from this pipe. The drainage pipe is connected to the feces collection device 3.

[0032] A flat valve 12 is provided below the stool trough, a water seal space is formed above the flat valve 12, a flat valve slideway 13 is provided on the side, and a scraping structure can be provided at the flat valve slideway provided on the side wall of the water seal space, so that when the flat valve moves into the flat valve slideway, the stool falling on the flat valve can be scraped off; the top of the flat valve is connected to the top of the airbag plug 14, and the airbag plug is respectively connected to the vacuum pump 15 and the air pump 16, and the vacuum pump and the air pump are controlled by the smart panel 17. In general, the airbag plug should be filled with air and drive the flat valve to close. When the toilet is finished, the smart panel controls the vacuum pump to evacuate the air in the airbag plug. At this time, the end of the airbag plug moves to the left, and the flat valve connected to the airbag plug will also enter the flat valve slideway to the left. At this point, the flat valve is opened and the stool is scraped off; then the smart panel controls the air pump to fill the airbag plug with air and move it to the right. At this time, the flat valve connected to the airbag plug will also leave the flat valve slideway to the right, and at this point, the flat valve is closed. The airbag plug is set here to prevent the flushing water above from flowing into the toilet collection device when the flat valve is not closed tightly, thereby achieving a secondary sealing effect.

[0033] The stool conveying device 2 is controlled by the smart panel 17, and the other end is connected to the stool collecting device 4. The smart panel starts the stool conveying device according to the signal of the flat valve closing, and conveys the stool to the stool collecting device.

[0034] Since the feces collection device belongs to an anaerobic environment, a certain amount of gas will be generated, so the urine collection device 3 and the feces collection device 4 are respectively provided with exhaust ports.

[0035] The flushing device is provided with a flushing button 18, a water inlet pipe 19, a water supply pipe 20, an overflow pipe 21, a flushing pipe 22 and a drain pipe 23, wherein the drain pipe is a P-type pipe and is arranged on the side of the water seal space.

[0036] In order to prevent the flushing water from entering the toilet collection device before the flat valve is closed, the flushing button 20 is controlled by the smart panel 17. When the flat valve is not closed, the flushing button cannot be pressed, and the flushing button can be pressed after the flat valve is closed.

[0037] The method for separating feces and urine sources provided by the present invention comprises the following steps:

[0038] 1) Open the cover and go to the toilet; when you get up, under the control of the smart panel (which can sense whether you get up or use buttons to control it), the vacuum pump starts, the airbag plug contracts and drives the flat valve to open; 2~3 seconds later, the smart panel controls the vacuum pump to shut down and the air pump to start. At this time, the airbag plug opens and drives the flat valve to close. 2~3 seconds later, the smart panel controls the air pump to shut down;

[0039] 2) When the vacuum pump is started, the intelligent panel controls the stool conveying device to start and shut down after 8-10 seconds;

[0040] 3) Manually press the flush button. If you are urinating, press the left button, and the flushing water volume is about 0.5L; if you are defecating, press the right button, and the flushing water volume is about 1L, which is much less than the traditional flush toilet;

[0041] 4) Most of the flushing water is discharged through the drain pipe, and a small part of the flushing water will enter the stool collection device through the urinary tube, but the amount of water is small and has almost no effect on the stool concentration.

[0042] The present invention can realize the separation of stool and flushing water, which not only saves water and improves the toilet environment, but also reduces the dilution effect of flushing water on stool, thereby reducing the amount of sewage treatment, reducing the concentration of pollutants, and greatly improving the fertilizer efficiency of stool.
