Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to an ecological PC assembled grooved toilet. Background Art

[0002] Public toilets are usually set up in stations, residential areas, streets, hospitals and other places. Existing public toilets use traditional structures, which make the decoration simple and the drainage pipes are installed underground or in the ceiling of the next floor. Each squatting position drainage riser needs to be repaired twice after passing through the floor or floor, but the quality of the repair is difficult to guarantee. Bricklaying and pouring concrete around the toilet will make it difficult to ensure the position of the toilet. In particular, the toilet end and the water supply pipe are manually wrapped with rubber tubes, which are not only prone to leakage, but also increase the installation cost. If a certain process is not properly constructed and causes cracks and leakage in the toilet, it will directly affect the use, and the toilet will lose its own performance. In addition, since the existing toilets have no protective mechanisms, each squatting position is equipped with an independent water tank for manual control or induction flushing, which consumes a lot of water and is costly. The water supply pipe is directly buried in the wall, which is inconvenient to maintain. It is easy to break and leak during an earthquake, and it will cause damage to the toilet, thereby shortening the service life of the toilet. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Ecological PC prefabricated flush trough toilets are designed for use within residential communities, train stations, and public restrooms, with partitions separating the squatting areas to create multiple toilet areas. To ensure water conservation and safety, these toilets offer specific toilet functions. The flush frequency and intervals are determined by the water flow (a float valve automatically opens when the tank is full). The flush frequency is controlled by the number of squatting positions, typically every three minutes for toilets with six or more, and every five minutes for toilets with less than six). Water from the tank flows into the main trough, where it is vortex-cut and dispersed by the propeller. This water is then flushed into the vortex-cutting system, filtered, and then discharged back into the tank for reuse, achieving this water-saving goal. This goal was achieved through BIM-based development of eco-friendly PC prefabricated flush trough toilets, including automated production and on-site assembly.

[0037] refer to Figures 1 to 7 To further explain this application, Figure 1 、 Figure 2 、 Figure 3 and Figure 6The ecological PC assembled flushing toilet shown in the figure includes several squatting bodies 1 connected in sequence. The discharge port of the squatting body 1 at the tail is connected to the cutting device 2. The cutting device 2 has an upper sewage outlet 27. The clean water tank 24 of the cutting device 2 is connected to the water tank system 4 through a water pump 25 and a return pipe 3 to realize wastewater utilization. The squatting body 1 has a main trough 111 and two flushing troughs 112. The two flushing troughs 112 are respectively located on both sides of the main trough 111. The flushing trough 112 is connected to the main trough 1 through multiple channels arranged side by side. 11 is connected to make the flushing radiation uniform. The water tank system 4 is connected with the main groove 111 and the two flushing small grooves 112 located at the head of the squatting body 1, and propellers 113 are provided on both sides of the inner wall of the main groove 111. The main groove 111 and the two flushing small grooves 112 flush water at the same time. After the flushing water encounters the propeller 113, a vortex is formed to cut and disperse the feces and flush them away. The water flushed out of the flushing small grooves 112 is used to suppress the splashing of the main groove 111 during flushing and to clean the side walls of the main groove 111. All the waste water after cleaning the main groove 111 enters the cutting device 2.

[0038] like Figure 2 、 Figure 3 and Figure 4 As shown, the present application preferably uses a groove with a circular cross-section, which can concentrate water force during flushing, and also make the inner wall of the main groove 111 have no dead corners, and the surface is smooth and not easy to stick to debris, and can have a self-cleaning function.

[0039] The squatting position body 1 includes a trough body 11, two supporting right-angled folded plates 12 and a pedal 13. The squatting position body 1 is formed by splicing to facilitate transportation and installation. The main trough 111 and the two flushing troughs 112 are located on the trough body 11. The two supporting right-angled folded plates 12 are buckled on both sides of the trough body 11. The pedal 13 is overlapped on the two supporting right-angled folded plates 12. The pedal 13 has the functions of splash prevention and squatting position control. The pedal 13 has a bar hole 131 connected to the main trough 111, and the propeller 113 is located below the pedal 13. The propeller 113 is not provided within the 150mm width of the bottom of the main trough 111. The propeller 113 is not provided at the bottom of the main trough 111 to ensure the flushing capacity and no loss of water head.

[0040] The pedal 13 is provided with a splash guard 132 at one end of the strip hole 131. This prevents urine from rushing out and allows the user to maintain a clean state for a long time.

[0041] The connection between the pedal 13 and the supporting right-angled folded plate 12 is provided with a plurality of cleaning holes 121 connected to the main groove 111, and the outer ends of the cleaning holes 121 extend to the top surface of the supporting right-angled folded plate 12. The provision of the cleaning holes 121 facilitates the sanitary cleaning of the supporting right-angled folded plate 12 without leaving any dead corners.

[0042] like Figure 4 and Figure 5 As shown, when the squatting position body 1 is installed, the connection between the trough body 11 and the supporting right-angle folded plate 12 is connected by a tongue-and-groove connection, and a waterproof rubber sealing strip is installed in the tongue-and-groove. Weather-resistant adhesive seals are added at the joints to enhance watertightness. The provision of the waterproof rubber sealing strip prevents water leakage and earthquake resistance, extending the service life of the present invention and preventing damage to people during earthquakes. When the pedal 13 is installed, structural adhesive is injected between the pedal 13, the supporting right-angle folded plate 12, and the trough body 11 to enhance integrity.

[0043] Specifically, the waterproof rubber sealing belt of the present application is a hollow professional rubber belt.

[0044] like Figure 6 As shown, the water tank system 4 includes a flushing tank 41 installed on the wall at one end of the squatting body 1 near the head, and the flushing tank 41 is connected to the water replenishment system. When the flushing interval time of this application is greater than the set time, it means that the water level in the flushing tank 41 cannot meet the function of continuous automatic interval flushing. The water replenishment system replenishes water until the flushing tank 41 releases the flushing and then stops replenishing water. The water outlet of the flushing tank 41 is connected to the main groove 111 of the squatting body 1 at the head through the main groove flushing pipe 42, and the water outlet of the flushing tank 41 is connected to the two flushing small grooves 112 of the squatting body 1 at the head through two small groove flushing pipes 43, so that the main groove 111 and the two flushing small grooves 112 are flushed at the same time. The principle of interval flushing control of the flushing tank 41 is to control the water flow rate by setting the power of the water pump 25, and to adjust the time required to fill the flushing tank 41 by adjusting the water flow rate, thereby controlling the number of interval flushing times. When the flushing tank 41 is full of water, the float valve automatically opens for flushing.

[0045] like Figure 7As shown, the cutting device 2 also includes an upper shell 21, the upper sewage outlet 27 is located at the top of the upper shell 21, and the upper shell 21 has a connecting port 22 that is connected to the discharge port of the squatting body 1 at the tail end. A rotary filter channel 23 and a cutting mechanism are provided in the upper shell 21. The feces entering the upper shell 21 through the connecting port 22 is cut by the cutting mechanism and then enters the rotary filter channel 23 along the tangential inlet of the rotary filter channel 23. The center of the rotary filter channel 23 is connected to the clean water tank 24, and the water pump 25 is located in the middle position of the clean water tank 24. The upper shell 21 is connected to the top of the clean water tank 24, and the outlet pipe of the water pump 25 passes through the center of the rotary filter channel 23. The bottom of the clean water tank 24 has a lower sewage outlet, wherein the cutting mechanism includes two rows of cutting rollers 28, and the connecting port 22 and the upper sewage outlet 27 are both located between the two rows of cutting rollers 28.

[0046] Specifically in this application, the rotary filtering channel 23 has at least five turns.

[0047] In order to facilitate the manufacture of the cutting device 2, the present application specifically provides a pressure cover 26 at the upper opening of the upper shell 21, and the upper sewage outlet 27 is located on the pressure cover 26. There is a certain distance between the pressure cover 26 and the top of the rotary filter channel 23.

[0048] When the cutting device 2 is working, the cutting rollers 28 (each of which has burrs) are driven by water to rotate to cut and break up the feces, so that the water forms a vortex. Some lightweight floating objects are directly discharged into the sewer pipe through the upper sewage outlet 27 under the action of water, and the remaining sewage and broken up feces will enter the rotary filter channel 23. When the broken up feces rotates in the rotary filter channel 23, they are further dispersed by the impact or friction of the water. After several filtrations, floating objects will float to the inner top surface of the pressure cover 26 and then be discharged to the upper sewage outlet 27 by the action of water. According to the floating principle, the feces are lighter than water after cutting. Some sewage enters the clean water tank 24, and some objects with a specific gravity greater than water sink to the bottom of the clean water tank 24. There are also certain floating objects on the water surface in the clean water tank 24, so the water pump 25 is installed in the middle of the clean water tank 24 to extract the clean water for use, and the debris heavier than water is discharged to the drain pipe through the lower sewage outlet.

[0049] like Figure 1 As shown, a transverse partition 5 connected to the wall at one end is provided between two adjacent squatting positions 1, and a longitudinal partition 6 is connected at the other end of the transverse partition 5. The height of the transverse partition 5 and the longitudinal partition 6 are both 90 mm, which is convenient for lighting and ventilation, and the thickness of the transverse partition 5 and the longitudinal partition 6 are both 50 mm.

[0050] The trough body 11, the supporting right-angle folded plate 12, the pedal 13, the transverse partition 5 and the longitudinal partition 6 are all made of concrete, and the concrete is formed by mixing one or more of crushed bricks or crushed concrete blocks or coal slag with oyster shell ash. The use of a variety of coarse aggregates after crushing construction waste can be combined to produce concrete surfaces of various required colors, and the use of concrete can be formed in one go without the need for decoration and renovation, and is in line with the current national requirements of green environmental protection, carbon peak and intelligent construction, saving labor and material costs and reducing construction costs. Among them, the concrete strength of the supporting right-angle folded plate 12 and the pedal 13 is C30. In order to enhance the strength of the supporting right-angle folded plate 12 and the pedal 13, as Figure 8 and Figure 9 As shown, the supporting right-angle folded plate 12 and the pedal 13 are both provided with a plurality of reinforcing steel bars. The diameter of the reinforcing steel bars in the supporting right-angle folded plate 12 that are consistent with the length direction of the supporting right-angle folded plate 12 is 6 mm, and the adjacent intervals are 150 mm. The diameter of the reinforcing steel bars in the supporting right-angle folded plate 12 that are perpendicular to the length direction of the supporting right-angle folded plate 12 is 6 mm, and the adjacent intervals are 200 mm. The diameter of the reinforcing steel bars in the pedal 13 that are consistent with the length direction of the pedal 13 is 4 mm, and the adjacent intervals are 150 mm. The diameter of the reinforcing steel bars in the pedal 13 that are perpendicular to the length direction of the pedal 13 is 4 mm, and the adjacent intervals are 200 mm. The specifications and distribution of the reinforcing steel bars in the transverse partition 5 and the longitudinal partition 6 are the same as those of the supporting right-angle folded plate 12.

[0051] When installing the present application, the squatting position body 1 is installed first, then the partition, then the water tank system 4, and finally the cutting device 2 in this order.

[0052] When the squatting position body 1 is installed, according to the overall layout of the bathroom detailed by the BIM software, the elevation of each squatting position is laid out before installation, points are drawn at the required positions according to the design elevation, and the ink fountain line is drawn at two points according to the implicit horizontal line. The squatting position is laid out according to the overall layout and the position is measured with a tape measure. The trough body 11 is adjusted to the laid-out position and fixed. After verifying that the elevation and position meet the requirements, the second trough body 11 is inserted into the tongue and groove of the previous trough body 11 and fixed. The installation is carried out one by one according to the above. The main drainage pipe of the squatting position is then installed. After the installation of multiple trough bodies 11 is completed, structural glue is injected at the junction of the trough body 11 and the trough body 11 to seal it for reliable waterproofing. The surface of the trough body 11 is cleaned of debris and structural glue is applied. The glue must be applied tightly to ensure that there is no leakage. Install the supporting right-angle folding plates 12 on both sides of the trough body 11, adjust the supporting right-angle folding plates 12 to align with the layout and the position of the trough body 11, and then install them one by one. After the installation of the supporting right-angle folding plates 12 is completed, apply structural glue at the junction for free. After the gluing is completed, install the pedal 13 immediately. Adjust the pedal 13 to align with the squatting position, install and fix it in place, and then install it one by one. After the installation of the pedal 13 is completed, seal it with structural glue at the junction. Carry out a water filling test 24 hours after the installation is completed. Before filling with water, seal the tail drain pipe with sandbags and then fill with water. The water filling height is based on the top surface of the trough body 11. If the water test is qualified, the acceptance will be organized.

[0053] When installing the partition, first plug and install the horizontal partition 5 on the wall and temporarily fix it. After checking that the elevation and verticality meet the requirements, install them one by one. After all the horizontal partitions 5 are installed, plug and install the longitudinal partition 6. After the longitudinal partition 6 is moved in, temporarily fix it. After adjusting the elevation and position to meet the requirements, install them one by one. After all the installation is completed, seal and fix all the joints with weather-resistant glue.

[0054] When installing the cutting device 2, first determine the size of the cutting device 2 based on the number of squatting positions and select the equipment. Verify the plane position and elevation before proceeding to the next step. First, assemble the cutting device 2. Then, connect the clean water pipe of the cutting device 2 to the water tank and temporarily fix it with bolts. After the test run is passed, tighten the bolts in place. After the installation is completed, conduct a test flush and test run.

[0055] The above installation method makes the installation of this application easy and simple, requires no technical content, has a short construction period, ensures product quality, is easy to transport, does not overlap with other processes, saves energy, is environmentally friendly and reduces noise, protects the environment, and is constructed in one process on site.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
