Description

Technical Field

[0001] This invention relates to the field of building drainage technology, and more particularly to a drainage and sewage system and a prefabricated building using the system. Background Technology

[0002] In prefabricated buildings, drainage and sewage pipes, as well as some small accessories, are directly pre-embedded in prefabricated components in the prefabrication factory, i.e., pre-embedded installation. To ensure good drainage performance, patent application CN202210271913.1 describes a prefabricated building and its sewage system, which includes a water supply connection pipe, a filter device, a cleaning device, and a flow-turbulence device. Essentially, it is a solid-liquid separation device. Its working principle is to use the filter device to block impurities in the sewage, separating the solids from the liquid. Then, as the sewage continues to flow, the solid impurities in the wastewater gradually clog the filter device. Under the impact of the sewage flow, the filter device gradually moves downwards to below the drain outlet on the guide rod. At this point, the cleaning device begins to clean the impurities clogging the filter device and concentrates the solid impurities into the guide pipe. Finally, the solid impurities are... Centralized treatment improves the efficiency of wastewater treatment; however, this solution has drawbacks, including its complex structure, high precision requirements, and inconvenience and flexibility in practical application, adjustment, and prefabrication. Furthermore, the holes on the main filter plate can only filter larger solids, but smaller particles or sticky substances (such as oil) cannot be effectively filtered. Impurities in the wastewater cannot clog the filter, rendering subsequent cleaning devices ineffective. In such cases, the structure cannot effectively treat the discharged wastewater, especially in scenarios with high environmental protection requirements. Therefore, we need a prefabricated building with better wastewater treatment capabilities. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a drainage and sewage system and a prefabricated building using the system. By adopting a modular design, the manufacturing difficulty during prefabrication is reduced, while facilitating subsequent processing and maintenance.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] The present invention provides a drainage and sewage system, including prefabricated building components and a drainage treatment string. The prefabricated building components are pre-installed with a plug-in part that cooperates with the drainage treatment string. During assembly, the drainage treatment string is inserted into the plug-in part to treat the building drainage. The drainage treatment string is box-shaped and includes, in the direction of sewage flow, an adsorption section, a magnetization section, a treatment section, and a sewage discharge section.

[0006] The adsorption section includes an adsorption chamber, in which an adsorption platform is fixedly installed. The adsorption platform divides the adsorption chamber into an inlet chamber and an outlet chamber. A detachably connected adsorption box is also provided on the adsorption platform. The adsorption box is filled with adsorption particles. After the sewage enters the inlet chamber, it passes through the adsorption box and enters the outlet chamber, and then flows to the magnetization section. The adsorption particles in the adsorption box are filled in several layers along the sewage flow direction. The adsorption particles are made of one or more of the following materials: activated carbon, oil-absorbing resin, sodium alginate and its derivatives, chitosan-based adsorption materials, diatomaceous earth-based adsorption materials, etc.

[0007] The magnetization section includes a magnetization cavity, which is trumpet-shaped. The cross-sectional area of ​​the magnetization cavity decreases along the direction of sewage flow. The magnetization section also has a magnetic cavity along the circumference of the magnetization cavity, and a magnet is installed in the magnetic cavity to form a magnetic field in the magnetization cavity. After the sewage enters the magnetization cavity and is magnetized, it flows to the treatment section.

[0008] The treatment section is equipped with a water flow channel, and the treatment section has several treatment tanks that cooperate with the water flow channel along the sewage flow direction. A treatment cake is inserted into the treatment tank, and sewage treatment agent is placed in the treatment cake to treat and filter the sewage. After the sewage flows through the treatment section, it flows to the sewage discharge section. The sewage discharge section is equipped with an outlet pipe and a collection box, so that the treated wastewater is introduced into the collection box through the outlet pipe.

[0009] It also includes a spiral section, which is disposed between the adsorption section and the magnetization section. The spiral section includes a spiral water passage cavity and a spiral part disposed within the spiral water passage cavity. The spiral part includes a spiral rod and a fixed plate. The spiral rod is coaxially arranged with the spiral water passage cavity. Both ends of the spiral rod are provided with integrally formed conical heads. The spiral rod is provided with threaded grooves. Both ends of the spiral rod are rotatably connected to the fixed plate. The fixed plate is provided with water passage holes. Both ends of the spiral water passage cavity are provided with insertion grooves that cooperate with the fixed plate. During sewage treatment, the fixed plate is inserted into the insertion grooves so that the spiral rod is located within the spiral water passage cavity.

[0010] The adsorption section, the spiral section, the magnetization section, the treatment section, and the sewage discharge section are all equipped with sealing covers.

[0011] The beneficial effects of this invention are as follows:

[0012] This invention employs a serial modular design, resulting in a simple overall structure that facilitates the production of prefabricated building components. Furthermore, the entire structure requires no complex control, and in practical applications, necessary parts can be proactively modified according to different usage scenarios. During subsequent cleaning and module adjustments, the drainage treatment components can be easily removed for operation. In prefabricated buildings, this effectively pre-treats wastewater generated by the building, improving the wastewater treatment capacity during drainage. Attached Figure Description

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1: As shown in the figure, this invention provides a drainage and sewage system, including a prefabricated building component 1 and a drainage treatment string 2. The prefabricated building component 1 has a pre-installed insertion part 11 that cooperates with the drainage treatment string 2. During assembly, the drainage treatment string 2 is inserted into the insertion part 11 to treat the building's drainage. The drainage treatment string 2 is box-shaped. This invention aims to effectively treat sewage in advance when it is discharged from the building. By pre-setting the insertion part 11 that cooperates with the drainage treatment string 2 during the manufacturing of the prefabricated building component 1 (such as prefabricated wall panels or prefabricated floor panels), the drainage treatment string 2 is inserted into the insertion part 11 during use. Later, when cleaning the drainage treatment string 2 or replacing the corresponding module as needed, the drainage treatment string 2 can be easily removed for operation. Furthermore, the drainage... The water treatment unit 2 includes, in sequence according to the direction of sewage flow, an adsorption section 21, a magnetization section 23, a treatment section 24, and a discharge section. Specifically, the adsorption section 21 includes an adsorption chamber 211, with an adsorption platform 212 fixed in the middle of the adsorption chamber 211. The adsorption platform 212 divides the adsorption chamber 211 into an inlet chamber 213 and an outlet chamber 214. The adsorption platform 212 is also equipped with a detachably connected adsorption box 215. The adsorption box 215 is filled with adsorption particles, and the adsorption particles in the adsorption box 215 are filled in several layers along the direction of sewage flow. The adsorption particles are made of one or more of the following materials: activated carbon, oil-absorbing resin, sodium alginate and its derivatives, chitosan-based adsorption materials, diatomaceous earth-based adsorption materials, etc., to ensure the adsorption of various impurities in the sewage. After entering the inlet chamber 213, the sewage passes through the adsorption box 215 and enters the outlet chamber 214, and then flows to the magnetization section 23.This allows for the configuration of the adsorption particle layer within the adsorption box 215 based on the main type of wastewater generated within the building. When periodic treatment and replacement of the adsorption particles within the adsorption box 215 are required, the drainage treatment connector 2 can be removed from the connector 11, and the adsorption box 215 can be taken out to adjust and replace the adsorption particle layer. Simultaneously, the entire adsorption chamber 211 can be cleaned. This makes wastewater treatment more flexible and targeted for different scenarios, ensuring environmental friendliness and sustainability. After the adsorption section 21, the wastewater passes through the magnetization section 23, which includes a magnetization chamber 231. The magnetization chamber 231 is trumpet-shaped, and its cross-sectional area decreases along the direction of wastewater flow. A magnetic cavity 232 is also provided circumferentially along the magnetization cavity 231. A magnet 233 is installed inside the magnetic cavity 232 to create a magnetic field within the magnetization cavity 231. After the wastewater enters the magnetization cavity 231 and is magnetized, it flows to the treatment section 24. The magnetization section 23 is mainly for magnetizing the wastewater. After magnetization, the wastewater is more effective in improving flocculation and oxidation, reducing the use of chemical agents and facilitating further treatment in the treatment section 24. Because the magnetization cavity 231 is funnel-shaped, its cross-sectional area can decrease more linearly, enhancing the magnetization effect as the wastewater passes through it. The water flow velocity increases as the cross-sectional area decreases, which may improve magnetization efficiency. Thus, the wastewater flows from... After flowing out of the magnetization section 23, the wastewater continues to flow into the treatment section 24. The treatment section 24 is equipped with a water passage 241, and several treatment tanks 242 that cooperate with the water passage 241 are opened in the treatment section 24 along the direction of wastewater flow. Treatment cakes 243 are inserted into the treatment tanks 242, and wastewater treatment agents are placed in the treatment cakes 243 to treat and filter the wastewater. After the wastewater flows through the treatment section 24, it flows to the discharge section. In this way, the magnetized wastewater can be further absorbed and treated by the treatment cakes 243 in the treatment section 24. Finally, the discharge section is equipped with an outlet pipe and a collection box, so that the treated wastewater can be introduced into the collection box through the outlet pipe. Preferably, a spiral section 22 is also included, which is set between the adsorption section 21 and the magnetization section 24. Between segments 23, the spiral segment 22 includes a spiral water passage cavity 221 and a spiral part 222 disposed within the spiral water passage cavity 221. The spiral part 222 includes a spiral rod 223 and a fixing plate 224. The spiral rod 223 is coaxially arranged with the spiral water passage cavity 221. Both ends of the spiral rod 223 are provided with integrally formed conical heads 2231. The spiral rod 223 is provided with threaded grooves 225. Both ends of the spiral rod 223 are rotatably connected to the fixing plate 224. The fixing plate 224 is provided with water passage holes 2241. Both ends of the spiral water passage cavity 221 are provided with insertion grooves 2211 that cooperate with the fixing plate 224. During sewage treatment, the fixing plate 224 is inserted into the insertion grooves 2211 so that the spiral rod 223 is located within the spiral water passage cavity 221.Wastewater exiting adsorption section 21 first enters spiral section 22. During the flow, the spiral rod 223 guides the water flow to form a vortex, which accelerates the water flow velocity. If necessary, a micro-motor can be added to drive the spiral rod 223 to actively rotate, thereby actively improving wastewater discharge efficiency.

[0037] Preferably, the adsorption section 21, spiral section 22, magnetization section 23, treatment section 24 and sewage discharge section are all equipped with sealing covers 25; while ensuring the drainage is sealed, they can be opened for subsequent cleaning and module replacement, making it convenient for adjustment.

[0038] In summary, this case adopts a series-type modular design, which is simple in structure and does not require complex control. In practical applications, the required parts can be actively modified according to different usage scenarios. In subsequent cleaning and module adjustment, the drainage treatment serial component 2 can also be easily removed for adjustment.

[0039] A prefabricated building employs an advanced drainage and sewage system, which effectively pre-treats the wastewater generated by the building and improves the wastewater treatment capacity of the prefabricated building during drainage.

[0040] Example 2: Unlike Example 1, in wastewater treatment, there may be some large impurities. In this case, the spiral section 22 needs to be set before the adsorption section 21. During the flow of wastewater, the cooperation between the spiral rod 223 and the threaded groove 225 uses the water flow and water pressure of the wastewater as a power source to accelerate the rotation of the entire spiral rod 223, which can form vortices and inward rolling forces to disperse and mix the impurities in the wastewater. This prevents blockage and also facilitates the efficient absorption of the adsorption section 21, improving the sewage discharge efficiency.

[0041] Example 3: Unlike Examples 1 and 2, the spiral section 22 is located between the magnetization section 23 and the treatment section 24; this allows the magnetized wastewater to enter the treatment section 24 at a higher speed, and then be absorbed and treated by the treatment cake 243, thereby further improving efficiency.

[0042] This invention has been described through preferred embodiments. The three embodiments described above are further descriptions in different scenarios. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this invention.
