Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a green building construction wastewater recycling device. Background Technology

[0002] Green building construction refers to the comprehensive implementation of sustainable development principles during the building process. This involves using environmentally friendly materials, energy-saving technologies, water-saving measures, and efficient management methods to minimize negative environmental impacts, while also emphasizing efficient resource utilization and safe and civilized construction site practices. It not only focuses on the environmental performance of the building itself but also strives to reduce energy consumption, pollution, and waste generated during construction activities, aiming to create a healthy, comfortable, efficient, and harmoniously integrated built environment with nature.

[0003] In green building construction, the application of wastewater recycling equipment is crucial, but existing technologies have significant shortcomings. After wastewater settles, these devices accumulate a large amount of impurities, and cleaning these sediments is extremely inconvenient. It typically requires manual opening of the equipment and slow removal with tools, which is not only labor-intensive and inefficient, increasing manpower burden, but also reduces cleaning efficiency. Furthermore, the addition of flocculants and the transport of wastewater to the reaction equipment rely on manual valve control, making precise control of chemical dosing and water intake difficult. This affects treatment efficiency and prevents consistent achievement of optimal results, thus limiting the convenience and efficiency of the equipment in green construction. Utility Model Content

[0004] One objective of this invention is to provide a green building construction wastewater recycling device. This invention addresses the issue mentioned in the background where, after wastewater sedimentation, a large amount of impurities accumulate inside, and cleaning these sediments is extremely inconvenient. Typically, it requires manual opening of the equipment and slow removal with tools, which is not only labor-intensive and inefficient, increasing manpower burden and reducing cleaning efficiency. Furthermore, the addition of flocculants and the transport of wastewater to the reaction equipment rely on manual valve control, making precise control of chemical dosing and water intake difficult, thus affecting treatment efficiency and preventing the stable achievement of optimal results. Overall, this limits the convenience and efficiency of the equipment in green construction.

[0005] A green building construction wastewater recycling device according to an embodiment of the present utility model includes:

[0006] The separation mechanism includes a reaction tank, a diversion box, and a separation screen cylinder connected below. A first rotating shaft is rotatably installed inside the reaction tank, and stirring blades are installed on the outside of the rotating shaft. A spiral conveying blade is rotatably installed inside the separation screen cylinder, and the spiral conveying blade is fixed to the output end of a servo motor. A slag discharge pipe is fixedly installed at one bottom end of the separation screen cylinder. The first rotating shaft is connected to the spiral conveying blade through a linkage component to achieve synchronous operation. A water pumping component for pumping wastewater is installed on the outside of the reaction tank.

[0007] The collection mechanism is installed at the bottom of the separation screen cylinder in the separation mechanism to achieve the separation and recycling of impurities and wastewater;

[0008] A quantitative conveying mechanism is installed outside the reaction tank in the separation mechanism to achieve quantitative control of the volume inside the reaction tank. The quantitative conveying mechanism includes a cross-shaped conveying tube fixed inside the reaction tank. A piston for blocking or releasing through holes is movably installed inside the cross-shaped conveying tube. A fixing rod is fixedly installed at the tail of the piston. A paddle that is rotatably connected to the cross-shaped conveying tube is sleeved on the outside of the fixing rod. A crank is fixedly installed on one side of the paddle. A floating ball is fixedly installed at one end of the crank.

[0009] The spray assembly, installed on one side of the diversion box in the separation mechanism, is used to prevent clogging of the separation screen cylinder during the separation process.

[0010] Preferably, the linkage component includes a first bevel gear fixed to the end of the spiral conveyor blade, a second rotating shaft rotatably disposed at the end of the diverter box, a second bevel gear meshing with the first bevel gear fixed at the bottom of the second rotating shaft, and a transmission belt installed between the second rotating shaft and the first rotating shaft.

[0011] Preferably, a protective box for protecting the bevel gear is installed between the bottom of the diversion box and the end of the separating screen cylinder.

[0012] Preferably, the pumping assembly includes a water delivery pipe installed on the outside of the reaction tank, and the water delivery pipe is fixed to the delivery end of the pump.

[0013] Preferably, the collection mechanism includes a wastewater collection tank installed at the bottom of the separating screen cylinder and an impurity collection tank at the bottom of the corresponding slag discharge pipe. A drain pipe and a sewage pipe are respectively fixed on one side of the wastewater collection tank and the impurity collection tank, and a bracket for supporting the separating screen cylinder is fixed on the top of the wastewater collection tank.

[0014] Preferably, the floating ball is located inside the reaction tank and is used to push or pull the piston after floating according to the water level.

[0015] Preferably, the spray assembly includes a circulating pump fixed to one side of the diversion box and a high-pressure spray head fixed to the bottom of the diversion box corresponding to the separation screen cylinder, and a circulation pipe is connected between the circulating pump and the wastewater collection tank in the collection mechanism.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problems of high workload and low efficiency in manual cleaning of sediments by setting up separation and collection mechanisms. In use, the water pumping component in the separation mechanism pumps construction wastewater into the reaction tank. Then, the first rotating shaft operates synchronously with the spiral conveying blades inside the separation screen cylinder through the first bevel gear, the second bevel gear, the second rotating shaft and the transmission belt in the linkage component. After the wastewater is pre-treated in the reaction tank, it is discharged into the separation screen cylinder. Large particles of impurities are intercepted by the screen cylinder. At this time, the rotating spiral conveying blades will push the impurities on the inner wall and bottom of the screen cylinder to one end, and finally automatically discharge them through the slag discharge pipe and fall into the impurity collection box below. At the same time, the treated clean water flows through the screen cylinder into the wastewater collection box below, thus eliminating the need for manual intervention, greatly reducing the burden of manpower, significantly improving cleaning efficiency, and ensuring the continuous and stable operation of the equipment.

[0018] This invention effectively avoids the problems of inaccurate control and unstable treatment efficiency caused by manual valve control when adding flocculants and transporting wastewater through a quantitative conveying mechanism. In use, after the wastewater enters the reaction tank, the quantitative conveying mechanism starts working. When the water level in the reaction tank rises, the floating ball rises accordingly. The crank pulls the lever and the fixed rod, causing the piston to move and block the through hole on the cross-shaped conveying pipe, preventing the reagent or wastewater from entering, thereby controlling the liquid level and volume in the reaction tank. Conversely, when the water level drops, the floating ball descends, and the lever is driven by the gravity of the crank and the floating ball to reset the piston, releasing the through hole and allowing the reagent or wastewater to enter for replenishment. This realizes the quantitative addition of reagents in the reaction tank and the automatic adjustment of wastewater flow, effectively avoiding the inaccuracy of manual operation and ensuring the stability of treatment efficiency and effect.

[0019] This invention effectively avoids the problem of impurities clogging the separation screen cylinder during the separation process by using a spray assembly. A circulation pump installed on one side of the distribution box starts, drawing pre-separated clean water from the wastewater collection tank below through a circulation pipe and transporting it to a high-pressure spray head fixed at the bottom of the distribution box, directly opposite the separation screen cylinder. The high-pressure spray head continuously sprays clean water onto the surface of the screen cylinder, which is separating wastewater. These high-pressure water jets impact the inner wall of the screen cylinder, effectively flushing away and carrying away fine mud, sand, mortar particles, and other impurities adhering to or clogging the screen cylinder's openings, maintaining the screen cylinder's permeability, ensuring the continuous and smooth wastewater separation process, and improving overall treatment efficiency.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-5 A green building construction wastewater recycling device, comprising:

[0029] The separation mechanism 1 includes a reaction tank 101, a diversion box 111, and a separation screen cylinder 102 connected below. A first rotating shaft 103 is rotatably mounted inside the reaction tank 101, and stirring blades 104 are installed on the outside of the shaft. A spiral conveying blade 105 is rotatably mounted inside the separation screen cylinder 102, and the spiral conveying blade 105 is fixed to the output end of a servo motor 106. A slag discharge pipe 115 is fixedly mounted at one bottom end of the separation screen cylinder 102. The first rotating shaft 103 is connected to the spiral conveying blade 105 via a linkage assembly to achieve synchronous operation. The linkage assembly includes a first bevel gear 107 fixed to the end of the spiral conveying blade 105, and a second rotating shaft 109 rotatably mounted to the end of the diversion box 111. The bottom of the second rotating shaft 109 is fixed... A second bevel gear 108 is provided to mesh with the first bevel gear 107. A transmission belt 110 is installed between the second shaft 109 and the first shaft 103. A water pumping assembly for pumping wastewater is installed on the outside of the reaction tank 101. In use, the water pumping assembly in the separation mechanism pumps construction wastewater into the reaction tank. Subsequently, the first shaft operates synchronously with the spiral conveying blades inside the separation screen cylinder through the first bevel gear, the second bevel gear, the second shaft and the transmission belt in the linkage assembly. Then, after the wastewater is pre-treated in the reaction tank, it is discharged into the separation screen cylinder. Large particles of impurities are intercepted by the screen cylinder. At this time, the rotating spiral conveying blades will continuously push the impurities on the inner wall and bottom of the screen cylinder to one end, and finally discharge them automatically through the slag discharge pipe.

[0030] Collection mechanism 2, installed at the bottom of separation screen cylinder 102 in separation mechanism 1, is used to separate and recycle impurities and wastewater. Collection mechanism 2 includes a wastewater collection tank 201 installed at the bottom of separation screen cylinder 102 and an impurity collection tank 202 at the bottom of corresponding slag discharge pipe 115. Drainage pipe 204 and sewage pipe 205 are respectively fixed on one side of wastewater collection tank 201 and impurity collection tank 202. For the convenience of subsequent treatment or discharge, drainage pipe 204 and sewage pipe 205 are respectively provided on one side of the two collection tanks. Drainage pipe 204 is connected to wastewater collection tank 201 for discharging treated clean water. A bracket 203 is fixed on the top of wastewater collection tank 201 to support separation screen cylinder 102.

[0031] A quantitative conveying mechanism 3 is installed outside the reaction tank 101 in the separation mechanism 1 to achieve quantitative control of the volume inside the reaction tank 101. The quantitative conveying mechanism 3 includes a cross-shaped conveying tube 301 fixed inside the reaction tank 101. A piston 302 for sealing or releasing through holes is movably disposed inside the cross-shaped conveying tube 301. A fixing rod 303 is fixedly disposed at the tail of the piston 302. A lever 304 rotatably connected to the cross-shaped conveying tube 301 is sleeved on the outside of the fixing rod 303. A crank rod 3 is fixedly disposed on one side of the lever 304. 05. A float ball 306 is fixedly installed at one end of the crank rod 305. When the water level in the reaction tank rises, the float ball rises accordingly. The crank rod pulls the lever and the fixed rod, causing the piston to move and block the through hole on the cross-shaped delivery pipe, preventing the reagent or wastewater from entering, thereby controlling the liquid level and volume in the reaction tank. Conversely, when the water level drops, the float ball drops, and the lever is driven by the gravity of the crank rod and the float ball to reset the piston, releasing the through hole and allowing the reagent or wastewater to enter for replenishment. This realizes the quantitative addition of reagents in the reaction tank and the automatic adjustment of wastewater flow.

[0032] The spray assembly 4 is installed on one side of the diversion box 111 in the separation mechanism 1 to prevent clogging on the separation screen cylinder 102 during the separation process. The spray assembly 4 includes a circulation pump 402 fixed on one side of the diversion box 111 and a high-pressure spray head 401 fixed at the bottom of the diversion box 111 corresponding to the separation screen cylinder 102. A circulation pipe 403 connects the circulation pump 402 and the wastewater collection tank 201 in the collection mechanism 2. When the circulation pump is started, it draws the preliminarily separated clean water from the wastewater collection tank below through the circulation pipe and delivers it to the high-pressure spray head fixed at the bottom of the diversion box and facing the separation screen cylinder. The high-pressure spray head continuously sprays clean water onto the surface of the screen cylinder that is separating wastewater. These high-pressure water jets impact the inner wall of the screen cylinder, which can effectively flush away and remove fine mud, sand particles and other impurities that are attached to or blocked on the screen cylinder holes, maintain the permeability of the screen cylinder, ensure the continuous and smooth wastewater separation process, and improve the overall treatment efficiency.

[0033] Example 1: A protective box 112 is installed between the bottom of the diversion box 111 and the end of the separation screen cylinder 102 to protect the bevel gears and other transmission components that may exist inside, so as to avoid them being interfered with or physically damaged by the external environment during the operation of the equipment, and to ensure stable and reliable transmission. The floating ball 306 is located inside the reaction tank 101 and is used to push or pull the piston 302 according to the water level. It can float up and down according to the change of water level inside the reaction tank 101. When the water level rises, the floating ball 306 will rise with it, thereby pushing or pulling the piston 302 connected to it; conversely, when the water level falls, the opposite action is produced.

[0034] Example 2: The water pumping assembly includes a water supply pipe 113 installed on the outside of the reaction tank 101. The water supply pipe 113 is fixed to the delivery end of the water pump 114. When the equipment is started, the water pump 114 starts to work. With its strong suction, it continuously pumps the external wastewater through the water supply pipe 113 and introduces it into the reaction tank 101, providing the necessary water source for subsequent mixing, reaction and separation treatment.

[0035] Working principle: First, the pumping assembly 2 is started. The pumping pump 114 pumps construction wastewater into the reaction tank 101 through the water delivery pipe 113. When the water level in the reaction tank 101 rises, the float ball 306 floats up. Through the crank rod 305, it pulls the lever 304 and the fixed rod 303, causing the piston 302 to move in the cross-shaped delivery pipe 301 to block the through hole, automatically cutting off the input of the reagent or wastewater. When the water level drops, the float ball 306 sinks, the piston 302 resets, releases the through hole, and resumes delivery. Subsequently, the servo motor 106 drives the spiral delivery blades 105 and drives the linkage assembly to rotate synchronously. The first rotating shaft 103 drives the second rotating shaft 109 through the transmission belt 110. The second shaft 109 is connected to the second bevel gear 108 in the linkage assembly. A bevel gear 107 engages, and after the wastewater is initially treated by the reaction tank 101, it is discharged into the separation screen cylinder 102. Large particles of impurities are intercepted by the screen cylinder, and the rotating spiral conveying blades 105 continuously push the impurities on the inner wall and bottom of the screen cylinder to one end. Finally, the impurities are automatically discharged to the impurity collection box 202 through the slag discharge pipe 115. The wastewater collection box 201 in the collection mechanism 2 collects the separated wastewater. The spray assembly 4 is started, and the circulation pump 402 draws clean water from the wastewater collection box 201 through the circulation pipe 403. The clean water is sprayed onto the surface of the separation screen cylinder 102 through the high-pressure spray head 401 to wash away and carry away fine impurities, maintaining the permeability of the screen cylinder. The treated clean water is discharged through the drain pipe 204, and the impurities are discharged through the sewage discharge pipe 205.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
