Description

Technical Field

[0001] The present invention relates to the technical field of building drainage, and in particular to a drainage and sewage system and an assembled building using the system. Background Art

[0002] In prefabricated buildings, drainage and sewage pipes and some small accessories are directly embedded in prefabricated parts in the prefabricated factory, that is, pre-embedded installation. In order to ensure good drainage and removal effects, the patent application with application number CN202210271913.1 records a prefabricated building and its sewage system, which includes a water supply connecting pipe, a filter device, a cleaning device and a spoiler device. It is essentially a solid-liquid separation device. The working principle is to use the filter device to block impurities in the sewage and separate the solids from the liquid in the sewage. Then, as the sewage continues to flow, the solid impurities in the wastewater gradually block the filter device. Under the impact of the sewage flow, the filter device gradually moves down to the bottom of the sewage outlet opened on the guide rod. At this time, the cleaning device begins to clean the impurities that block the filter device, and concentrate the solid impurities in the guide pipe. Finally, the solid impurities are Centralized treatment improves the efficiency of sewage treatment; however, the defect of this solution is that its structure is quite complicated, and the degree of refinement is high. It is not convenient and flexible in actual application adjustment and prefabrication. Moreover, the holes set on the main filter plate can only filter some larger solid substances, but for some smaller particles or some sticky substances (such as oil, etc.), the impurities in the wastewater cannot block the filtering device, so the subsequent cleaning device cannot play an effective role. At this time, the structure cannot effectively treat the discharged sewage, especially in scenarios with high environmental protection requirements. The above solution is no longer applicable, and it is not convenient for subsequent cleaning and maintenance. Therefore, we need a prefabricated building with better sewage treatment function.

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] Embodiment 1: As shown in the figure, the present invention provides a drainage and sewage system, including a building prefabricated component 1, and also including a drainage treatment string component 2. The building prefabricated component 1 is pre-set with a plug-in portion 11 that cooperates with the drainage treatment string component 2. During assembly, the drainage treatment string component 2 is plugged into the plug-in portion 11 to treat the building drainage; the drainage treatment string component 2 is box-shaped, and the present case is intended to use the drainage treatment string component 2 in advance to effectively treat the sewage when the sewage is discharged from the building. When the building prefabricated component 1 (such as prefabricated wall panels or prefabricated floors) is manufactured, the plug-in portion 11 that cooperates with the drainage treatment string component 2 is pre-set. In this way, when in use, the drainage treatment string component 2 is inserted into the plug-in portion 11, and then when the drainage treatment string component 2 needs to be cleaned or the corresponding module needs to be replaced later, the drainage treatment string component 2 can be conveniently taken out for operation. Furthermore, the drainage The water treatment string 2 includes an adsorption section 21, a magnetization section 23, a treatment section 24 and a sewage discharge section in sequence according to the flow direction of the sewage; specifically, the adsorption section 21 includes an adsorption chamber 211, and an adsorption platform 212 is fixedly provided in the middle of the adsorption chamber 211. The adsorption platform 212 divides the adsorption chamber 211 into a water inlet chamber 213 and a water outlet chamber 214. A detachably connected adsorption box 215 is also provided on the adsorption platform 212. The adsorption box 215 is filled with adsorption particles, and the adsorption particles in the adsorption box 215 are filled with several layers along the flow direction of the sewage. The material of the adsorption particles includes one or more of activated carbon, oil-absorbing resin, sodium alginate and its derivative materials, chitosan adsorption materials, diatomaceous earth adsorption materials, etc.; to ensure the adsorption of various impurities in the sewage, the sewage enters the water inlet chamber 213 and enters the water outlet chamber 214 through the adsorption box 215, and then flows to the magnetization section 23;In this way, the adsorption particle layer in the adsorption box 215 can be set according to the main type of sewage generated in the building. Then, when the adsorption particles in the adsorption box 215 need to be processed and replaced regularly, the drainage treatment string 2 can be taken out from the plug-in part 11, and then the adsorption box 215 is taken out to adjust the adsorption particle layer in each replacement adsorption box 215, and the entire adsorption chamber 211 is cleaned at the same time, so that it is more flexible and targeted when treating sewage in different scenarios, ensuring environmental friendliness and environmental protection. After passing through the adsorption section 21, it must pass through the magnetization section 23. The magnetization section 23 includes a magnetization cavity 231. The magnetization cavity 231 is trumpet-shaped. The cross-sectional area of ​​the magnetization cavity 231 decreases along the direction of sewage flow. A magnetic chamber 232 is also provided along the circumference of the magnetizing chamber 231. A magnet 233 is provided in the magnetic chamber 232 to form a magnetic field in the magnetizing chamber 231. After the sewage enters the magnetizing chamber 231 and is magnetized, it flows to the treatment section 24. The magnetizing section 23 is mainly used to magnetize the sewage. After the sewage is magnetized, it is beneficial to improve the flocculation effect and the oxidation treatment effect, so as to reduce the use of chemical agents and facilitate the subsequent further treatment in the treatment section 24. Since the magnetizing chamber 231 is trumpet-shaped, the cross-sectional area of ​​the magnetizing chamber 231 can be more linearly decreased to enhance the magnetization effect of the sewage when it passes through the magnetizing chamber 231. The water flow velocity will increase with the reduction of the cross-sectional area, which may be beneficial to improve the magnetization efficiency; thus, the sewage flows from After the magnetized section 23 flows out, it continues to flow into the treatment section 24; the treatment section 24 is provided with a water flow channel 241, and the treatment section 24 is provided with a plurality of treatment tanks 242 that cooperate with the water flow channel 241 along the flow direction of the sewage, and a treatment cake 243 is inserted in the treatment tank 242, and a sewage treatment agent is arranged in the treatment cake 243 to treat and filter the sewage. After the sewage flows through the treatment section 24, it flows to the sewage discharge section, so that the magnetized sewage can be further absorbed and treated by the treatment cake 243 in the treatment section 24; finally, the sewage discharge section is provided with an outlet pipe and a collection box, so that the treated wastewater is introduced into the collection box by the outlet pipe; preferably, it also includes a spiral section 22, which is arranged between the adsorption section 21 and the magnetized section 24. The spiral section 22 includes a spiral water chamber 221 and a spiral portion 222 disposed in the spiral water chamber 221. The spiral portion 222 includes a spiral rod 223 and a fixed plate 224. The spiral rod 223 is coaxially disposed with the spiral water chamber 221. Both ends of the spiral rod 223 are provided with an integrally formed conical head 2231. The spiral rod 223 is provided with a threaded groove 225. Both ends of the spiral rod 223 are rotatably connected with the fixed plate 224. The fixed plate 224 is provided with a water hole 2241. Both ends of the spiral water chamber 221 are provided with a plug-in groove 2211 that cooperates with the fixed plate 224. When sewage is treated, the fixed plate 224 is inserted into the plug-in groove 2211 so that the spiral rod 223 is located in the spiral water chamber 221.In this way, the sewage from the adsorption section 21 will first enter the spiral section 22, and then during the flow process, the spiral rod 223 can guide the water flow to form a vortex, which can accelerate the flow rate of the water. If necessary, a micro motor can also be added to drive the spiral rod 223 to actively rotate, so as to actively improve the sewage discharge efficiency. ;

[0037] Preferably, the adsorption section 21, the spiral section 22, the magnetization section 23, the processing section 24 and the sewage discharge section are all provided with a sealing cover 25; while ensuring the drainage sealing, it can be opened during subsequent cleaning and module replacement for easy adjustment.

[0038] In summary, this case generally adopts a serial modular design. The entire structure is simple and does not require complex control. In actual application, the required parts can be actively modified according to different usage scenarios. During subsequent cleaning and module adjustments, the drainage treatment string 2 can also be conveniently taken out for adjustment.

[0039] An assembled building adopts the above drainage and sewage system, which can effectively pre-treat the sewage generated by the building and improve the sewage treatment capacity of the assembled building during drainage.

[0040] Embodiment 2: The difference from Embodiment 1 is that during sewage treatment, there may be some larger impurities. In this case, the spiral section 22 needs to be arranged before the adsorption section 21. During the flow of sewage, the cooperation between the spiral rod 223 and the thread groove 225 uses the flow and water pressure of the sewage during drainage as the power source to accelerate the rotation of the entire spiral rod 223, thereby forming eddy currents and involution forces to break up and mix the impurities in the sewage. While preventing blockage, it also facilitates the efficient absorption of the adsorption section 21 and improves the sewage discharge efficiency.

[0041] Embodiment 3: Different from Embodiments 1 and 2, the spiral section 22 is arranged between the magnetization section 23 and the treatment section 24; this allows the magnetized sewage to enter the treatment section 24 at a higher speed, and then be absorbed and treated by the treatment cake 243, so that the efficiency is further improved.

[0042] The present invention is described by preferred embodiments, and the above three embodiments are further described in different scenarios. Those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application belong to the scope of protection of the present invention.
