Description

Technical Field

[0001] This utility model belongs to the field of wastewater purification technology, and in particular relates to a purification and reuse device for building and domestic wastewater. Background Technology

[0002] Domestic wastewater refers to the wastewater generated by residents in their daily lives, mainly including wastewater from washing, bathing, and kitchen drainage. This wastewater contains organic matter, suspended solids, and trace amounts of harmful substances. To conserve water resources, domestic wastewater is purified and reused, for example, for irrigation and floor cleaning.

[0003] Chinese utility model patent CN222998406U discloses a construction wastewater reuse device. By setting up a filter mechanism and a vibration component to work together, the construction wastewater first passes through a filter cylinder two to separate the water from the construction waste. The waste then falls into a slag discharge box and a slag discharge plate according to the size of the construction waste. At the same time, the wastewater is filtered and flows into a drainage plate. The vibration component drives the movable plate area to generate a slight vibration, making the flow of wastewater smoother and reducing the drainage retention time.

[0004] Research revealed that the aforementioned devices can only screen larger impurities. Wastewater typically contains bacteria and harmful substances, and the devices lack disinfection capabilities, impacting wastewater safety. Therefore, there is an urgent need to improve existing wastewater purification and reuse devices to provide a purification and reuse system for construction and domestic wastewater. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reasonably designed, simple structure, better purification effect, and disinfection function for the purification and reuse of building wastewater, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for purifying and reusing construction wastewater, comprising:

[0008] A preliminary filtration mechanism includes an inlet tank fixedly installed on the top of an inclined tube sedimentation tank, a primary filter plate fixedly installed on the inner side of the inlet tank at an incline, and a storage tank for temporarily storing filtered impurities fixedly installed on the left side of the inlet tank.

[0009] The disinfection mechanism includes multiple ultraviolet disinfection lamps that are equidistantly fixed on the inner wall of the upper end of the disinfection tank in a vertical direction, and a chlorine dioxide generator located directly behind the disinfection tank. The gas output port of the chlorine dioxide generator is fixedly connected to the disinfection component through a connecting pipe.

[0010] A dispersion component is fixedly installed inside the top of the disinfection tank and located above the ultraviolet disinfection lamp, for dispersing the water flow.

[0011] The discharge pipe is fixedly installed at the bottom of the disinfection tank and is used to transport the disinfected and purified wastewater for secondary use. A water guide pipe is fixedly installed on the top of the disinfection tank, and the other end of the water guide pipe is fixedly connected to the drain outlet on the right side of the top of the inclined tube sedimentation tank. A detachable gas filter element for gas purification is installed on the upper right side of the disinfection tank.

[0012] In a preferred embodiment, both the inclined tube sedimentation tank and the disinfection tank have a funnel-shaped bottom, and a drain valve is fixedly installed at the bottom drain outlet of the inclined tube sedimentation tank.

[0013] In a preferred embodiment, the dispersing component includes a dispersing disc, connecting blocks, a water guiding ring, guiding grooves, and water permeable holes. The water guiding ring is fixedly installed on the top inner wall of the disinfection tank. A conical dispersing disc is fixedly installed on the inner side of the water guiding ring through multiple annularly distributed connecting blocks. The surface of the dispersing disc is provided with several guiding grooves in an annular pattern.

[0014] In a preferred embodiment, each of the guide grooves has water-permeable holes equidistantly spaced along its length on its inner bottom surface, and the dispersion disc, connecting block and water guide ring form several annularly distributed water-permeable grooves.

[0015] In a preferred embodiment, the disinfection assembly includes an annular tube, a flow equalization tube, and nozzles. The annular tube is fixedly installed on one end of the connecting tube located inside the disinfection tank. A cross-shaped flow equalization tube is fixedly connected to the inner side of the annular tube. Multiple nozzles are uniformly fixedly installed on the upper surfaces of both the annular tube and the flow equalization tube for spraying chlorine dioxide gas.

[0016] In a preferred embodiment, a control mechanism is also included, which is a controller fixed on the outer wall of the right side of the disinfection tank, used to control the operation of the ultraviolet disinfection lamp and the chlorine dioxide generator.

[0017] In a preferred embodiment, the left side of the storage box is connected to a cleaning door via a hinge, and a door lock for positioning is installed on the cleaning door.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the solution of this utility model:

[0020] This device utilizes a primary filter plate and an existing inclined tube sedimentation tank to thoroughly screen out and filter solid impurities in wastewater. As wastewater is continuously input, the wastewater with solid impurities removed can enter the disinfection tank through a water pipe. At this time, the chlorine dioxide generator is turned on, and chlorine dioxide gas is introduced into the disinfection tank. In conjunction with multiple equally spaced ultraviolet disinfection lamps, the wastewater can be disinfected, thus achieving a highly efficient purification effect and facilitating wastewater recycling and safe reuse.

[0021] The chlorine dioxide gas generated by the chlorine dioxide generator is fed into the ring pipe and the equalization pipe through the connecting pipe, and sprayed upward through multiple evenly distributed nozzles. The wastewater sent into the disinfection tank through the water guide pipe can be divided into several small streams and flow down through the dispersion plate, multiple guide grooves and several water permeable holes, which facilitates full contact between the wastewater and chlorine dioxide gas and ultraviolet light, making it easier to disinfect the wastewater more thoroughly and ensuring higher water safety.

[0030] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0031] like Figure 1-5 As shown, the present invention relates to a purification and reuse device for building domestic wastewater, which includes:

[0032] The preliminary filtration mechanism includes an inlet tank 2 fixedly installed at the top of the inclined tube sedimentation tank 1, a primary filter plate 3 fixedly installed on the inner side of the inlet tank 2 at an incline, and a storage tank 4 for temporarily storing filtered impurities fixedly installed on the left side of the inlet tank 2.

[0033] The disinfection mechanism includes multiple ultraviolet disinfection lamps 7 that are fixed at equal intervals along the vertical direction on the inner wall of the upper end of the disinfection tank 6, and a chlorine dioxide generator 14 located directly behind the disinfection tank 6. The gas output port of the chlorine dioxide generator 14 is fixedly connected to the disinfection component 9 through a connecting pipe 15.

[0034] The dispersion component 8 is fixedly installed inside the top of the disinfection tank 6 and located above the ultraviolet disinfection lamp 7, and is used to disperse the water flow.

[0035] The discharge pipe 10 is fixedly installed at the bottom of the disinfection tank 6 and is used to transport the disinfected and purified wastewater for secondary use. A water guide pipe 11 is fixedly installed on the top of the disinfection tank 6, and the other end of the water guide pipe 11 is fixedly connected to the drain outlet on the right side of the top of the inclined tube sedimentation tank 1. A detachable gas filter element 12 for gas purification is installed on the upper right side of the disinfection tank 6.

[0036] Based on the above structure, both the inclined tube sedimentation tank 1 and the disinfection tank 6 have a funnel-shaped bottom, and a drain valve 5 is fixedly installed at the bottom drain port of the inclined tube sedimentation tank 1.

[0037] In this embodiment, the drain valve 5 is used to facilitate the discharge and cleaning of solid impurities filtered out by the inclined tube sedimentation tank 1.

[0038] Based on the above structure, the dispersion component 8 includes a dispersion disc 81, a connecting block 82, a water guide ring 83, a guide groove 84, and a water permeable hole 85. The water guide ring 83 is fixedly installed on the top inner wall of the disinfection tank 6. A conical dispersion disc 81 is fixedly installed on the inner side of the water guide ring 83 through multiple annularly distributed connecting blocks 82. The surface of the dispersion disc 81 is provided with several guide grooves 84 in annular shape.

[0039] Based on the above structure, each guide groove 84 has water-permeable holes 85 equidistantly opened on its inner bottom surface along its length direction, and the dispersion plate 81, the connecting block 82 and the water guide ring 83 form a number of annularly distributed water-permeable grooves.

[0040] In this embodiment, the wastewater sent into the disinfection tank 6 by the water pipe 11 can be divided into several small streams through the dispersion plate 81, multiple guide grooves 84 and several water permeable holes 85, which facilitates the full contact between the wastewater and chlorine dioxide gas and ultraviolet light, and facilitates more thorough disinfection of the wastewater.

[0041] Based on the above structure, the disinfection component 9 includes an annular tube 91, a flow equalization tube 92, and nozzles 93. The annular tube 91 is fixedly installed on one end of the connecting tube 15 located inside the disinfection tank 6. The inner side of the annular tube 91 is fixedly connected to the cross-shaped flow equalization tube 92. Multiple nozzles 93 are evenly fixedly installed on the upper surfaces of both the annular tube 91 and the flow equalization tube 92 for spraying chlorine dioxide gas.

[0042] In this embodiment, the chlorine dioxide gas generated by the chlorine dioxide generator 14 is input into the annular pipe 91 and the flow equalization pipe 92 through the connecting pipe 15, and can be sprayed upward through multiple evenly distributed nozzles 93 to achieve the purification and disinfection of wastewater.

[0043] Based on the above structure, a control mechanism is also included. The control mechanism is a controller 13 fixed on the outer wall of the right side of the disinfection tank 6, which is used to control the operation of the ultraviolet disinfection lamp 7 and the chlorine dioxide generator 14.

[0044] In this embodiment, both the controller 13 and the chlorine dioxide generator 14 are existing electrical devices, and their specific control and working principles adopt mature existing technologies.

[0045] Based on the above structure, a cleaning door 16 is connected to the left side of the storage box 4 via a hinge, and a door lock 17 for positioning is installed on the cleaning door 16.

[0046] In this embodiment, the cleaning door 16 facilitates the cleaning of larger solid impurities that have been recycled into the storage bin 4.

[0047] The working principle of this utility model is as follows:

[0048] In use, wastewater is first discharged into the inlet tank 2. During this process, the inclined primary filter plate 3 can screen out larger solid impurities and temporarily collect them in the storage tank 4. Then, the existing inclined tube sedimentation tank 1 can screen out and filter smaller solid impurities. As wastewater continues to be input, the wastewater with solid impurities removed can enter the disinfection tank 6 through the guide pipe 11. When the wastewater falls onto the dispersion plate 81, it can be divided into several small streams and flow down through multiple annularly distributed guide grooves 84 and several water permeable holes 85. At this time, the chlorine dioxide generator 14 is turned on, and chlorine dioxide gas is input into the annular pipe 91 and the equalization pipe 92 through the connecting pipe 15, and sprayed upward through multiple evenly distributed nozzles 93 to facilitate the full contact and reaction between the wastewater and the chlorine dioxide gas. At the same time, it works in conjunction with multiple equidistantly distributed ultraviolet disinfection lamps 7 to achieve full disinfection of the wastewater, thereby achieving a highly efficient purification effect on the wastewater. The discharge pipe 10 facilitates the recycling and reuse of wastewater. Moreover, after filtration and disinfection, the water safety is higher.

[0049] It should be noted that this device is powered by an external power source. The inclined tube sedimentation tank 1, ultraviolet disinfection lamp 7, controller 13 and chlorine dioxide generator 14 are all existing and common electrical equipment. Their specific control and working principles all adopt mature existing technologies, so they will not be described in detail.

[0050] After the wastewater purification is completed, the cleaning door 16 and the drain valve 5 can be opened to clean and discharge the filtered solid impurities.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
