Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater recycling device for a waste treatment plant. Background Technology

[0002] As people's environmental awareness increases, wastewater treatment is gradually gaining attention. Wastewater treatment in waste treatment plants uses physical, chemical, and biological methods to purify the wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources.

[0003] The original waste treatment plant's water tank was small. If the water pump's pumping power was too high, it could easily cause a vacuum in the water tank, affecting the condenser used for wastewater recovery. This could lead to insufficient water flow guidance after the condenser malfunctioned, and cause an imbalance in the liquid level control between the water pump and the water tank, resulting in overflow. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wastewater recycling device for waste treatment plants. This device solves the problem that the water tanks in existing waste treatment plants are small, and if the pumping power is too high, it can easily cause a vacuum in the water tank, which affects the condenser of the wastewater recycling system. This can lead to insufficient water flow guidance after the condenser malfunctions, and cause overflow due to uneven liquid level control between the pump and the water tank.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a wastewater recycling device for a waste treatment plant, comprising a shallow sand filter, a drainage channel, a switch valve, a sewage pipe, a liquid level control device, a circulating water reserved pipe, a cooling tower downcomer, and a water tank. The shallow sand filter, drainage channel, switch valve, and sewage pipe are externally located around the waste treatment plant. The drainage channel is interconnected with the sewage pipe through the switch valve. The drainage channel and the switch valve are installed directly below the sewage pipe. The shallow sand filter is interconnected with the sewage pipe through the valve. There are two or more shallow sand filters, all installed side by side between the drainage channel and the sewage pipe.

[0006] The liquid level control device, circulating water reserved pipe, cooling tower downpipe, and water tank are all built inside the waste treatment plant. The liquid level control device is installed in the upper left corner of the cooling tower downpipe. There are two or more cooling tower downpipes, all of which are inserted into the top of the circulating water reserved pipe. The circulating water reserved pipe is installed on the left side of two or more water tanks. The circulating water reserved pipe is interconnected with the drainage channel through the water tank.

[0007] By combining and connecting the equipment and pipelines inside and outside the waste treatment plant, a continuous effect of wastewater recycling and water purification operation is achieved through the circulation of wastewater inside and outside the plant.

[0008] Preferably, the shallow sand filter is provided with a feeding port, a filter tank, an observation window, and a discharge port. The feeding port and the discharge port are respectively fixed at the upper and lower ends of the front side of the filter tank, and the observation window is fixed at the front end of the filter tank. The filter tank is interconnected with the sewage pipe through a valve.

[0009] Chemical reagents are added through the feed inlet to perform calcification treatment on the shallow sand inside the filter tank, stabilizing the purified water. Furthermore, the wastewater from the waste treatment plant is filtered and settled efficiently through the circulation of three filter tanks.

[0010] Preferably, the liquid level control device includes a water storage tank, a water pump, a condenser, and a condenser. The water pump is inserted into the top of the water storage tank. The water storage tank and the condenser are respectively installed on the left and right sides in front of the condenser. The water storage tank is connected to the cooling tower downcomer through a pipe.

[0011] The condenser between the water storage tank and the condenser ensures that the wastewater from the waste treatment plant can be condensed and treated by water vapor sedimentation during high-temperature recovery. The water is then circulated and introduced into a shallow sand filter through pipelines for water purification.

[0012] Preferably, the water storage tank is provided with a top opening slot, a damping nozzle, a storage inner tank, and a float control valve. The top opening slot is installed on the top of the storage inner tank, and the float control valve is built into the storage inner tank with a clearance fit. The top opening slot is nested with the storage inner tank as one unit through the damping nozzle.

[0013] The damping nozzle and float control valve ensure the balance of the liquid level by controlling the float index. When water overflow occurs, the damping nozzle is pressurized and tightens the top opening groove and the inner storage tank to ensure safety and prevent overflow.

[0014] Preferably, the condenser is provided with a connecting pipe and a condensation pipe tank. The connecting pipe is inserted into the left side of the condensation pipe tank, and the condensation pipe tank is interconnected with the water storage tank through the connecting pipe.

[0015] By connecting the condensate tank with the connecting pipe, the principle of the communicating vessel is realized to conduct high and low water flow and water vapor circulation, sedimentation and circulation effect, ensuring the purification and circulation operation of wastewater recycling in the waste treatment plant.

[0016] Preferably, the circulating water reserved pipe is provided with an inlet channel and a water pump inlet pipe. There are two or more water pump inlet pipes, all of which are inserted into the right side of the inlet channel. The water pump inlet pipes are interconnected with the cooling tower downcomer pipe through the inlet channel.

[0017] The inlet channel and the water pump inlet pipe form a horizontal and vertical three-dimensional spatial arrangement of pipes under the cooling tower downpipe, which are interconnected to circulate water. This increases the number of circulating water pipe structures, promoting the flow and discharge of wastewater for recycling in the waste treatment plant.

[0018] This utility model provides a wastewater recycling device for waste treatment plants, which has the following beneficial effects:

[0019] This wastewater recycling device for waste treatment plants allows workers to increase the number of water tanks and the capacity of the waste treatment plant by expanding the water storage tank, adding a level control device, and increasing the number of circulating water pipes and cooling tower downcomers (i.e., circulating water connection pipes). When the water pump's pumping power is too high, there is sufficient water supply in the storage tank and the water tank, avoiding the occurrence of vacuum phenomena. It has no impact on the condenser of the wastewater recycling in the waste treatment plant, stabilizing the condenser and ensuring smooth flow and recycling of the wastewater. The level control between the water pump and the water tank is balanced and there is no overflow or backflow through the float control valve. At the same time, it can reduce previous manual handling and realize the detection and control of condensate recycling through online level control. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides a wastewater recycling device for a waste treatment plant, including a shallow sand filter 1, a drainage channel 2, a switch valve 3, a sewage pipe 4, a liquid level control device 5, a circulating water reserved pipe 6, a cooling tower downcomer 7, and a water tank 8. The shallow sand filter 1, drainage channel 2, switch valve 3, and sewage pipe 4 are externally located around the waste treatment plant. The drainage channel 2 is interconnected with the sewage pipe 4 through the switch valve 3. The drainage channel 2 and the switch valve 3 are installed directly below the sewage pipe 4. The shallow sand filter 1 is interconnected with the sewage pipe 4 through the valve. There are two or more shallow sand filters 1, all installed side by side between the drainage channel 2 and the sewage pipe 4.

[0029] The liquid level control device 5, the circulating water reserved pipe 6, the cooling tower downpipe 7, and the water tank 8 are all built inside the waste treatment plant. The liquid level control device 5 is installed at the upper left corner of the cooling tower downpipe 7. There are two or more cooling tower downpipes 7, all of which are inserted into the top of the circulating water reserved pipe 6. The circulating water reserved pipe 6 is installed on the left side of two or more water tanks 8. The circulating water reserved pipe 6 is interconnected with the drainage channel 2 through the water tank 8.

[0030] It should be noted that the combination of equipment and pipelines inside and outside the waste treatment plant creates a continuous effect of wastewater recycling and water purification operations by circulating the wastewater inside and outside the plant.

[0031] Because the original waste treatment plant's water tank was small, if the water pump's pumping power was too high, it could easily cause a vacuum in the water tank, affecting the condenser used for wastewater recovery. This could lead to insufficient water flow guidance after the condenser malfunctioned, and cause overflow and backflow due to uneven liquid level control between the water pump and the water tank.

[0032] The shallow sand filter 1 is provided with a feeding port 11, a filter tank 12, an observation window 13, and a discharge port 14. The feeding port 11 and the discharge port 14 are respectively fixed at the upper and lower ends of the front side of the filter tank 12. The observation window 13 is fixed at the front end of the filter tank 12. The filter tank 12 is connected to the sewage pipe 4 through a valve.

[0033] It should be noted that chemical reagents are added through the feed port 11 to the shallow sand in the filter tank 12 for calcification treatment to stabilize the purified water, and the wastewater from the waste treatment plant is filtered and settled efficiently through the circulation of the three filter tanks 12.

[0034] The liquid level control device 5 is equipped with a water storage tank 51, a water pump 52, a condenser 53, and a condenser 54. The water pump 52 is inserted into the top of the water storage tank 51. The water storage tank 51 and the condenser 54 are respectively installed on the left and right sides in front of the condenser 53. The water storage tank 51 is connected to the cooling tower downcomer 7 through a pipe.

[0035] It should be noted that the condenser 53 between the water storage tank 51 and the condenser 54 ensures that the wastewater from the waste treatment plant can be condensed and treated by water vapor sedimentation during high-temperature recovery, and can be circulated and introduced into the shallow sand filter 1 through the pipeline for water purification.

[0036] The water storage tank 51 is provided with a top opening slot 511, a damping constriction port 512, a storage inner tank 513, and a float control valve 514. The top opening slot 511 is installed on the top of the storage inner tank 513, and the float control valve 514 is built into the storage inner tank 513 and is fitted with a clearance. The top opening slot 511 is nested with the storage inner tank 513 as one unit through the damping constriction port 512.

[0037] It should be noted that the damping nozzle 512 and the float control valve 514 ensure the balance of the float index control liquid level. When water overflow occurs, the damping nozzle 512 is pressure-tightened to the top opening groove 511 and the storage inner tank 513 to ensure safety and prevent overflow.

[0038] The condenser 54 is provided with a connecting pipe 541 and a condensation pipe tank 542. The connecting pipe 541 is inserted into the left side of the condensation pipe tank 542, and the condensation pipe tank 542 is interconnected with the water storage tank 51 through the connecting pipe 541.

[0039] It should be noted that by connecting the connecting pipe 541 to the condensate tank 542, the principle of the communicating vessel is realized to conduct high and low water flow and water vapor circulation sedimentation and circulation effect, so as to ensure the purification water extraction and circulation operation effect of wastewater recycling in the waste treatment plant.

[0040] The circulating water reserved pipe 6 is provided with an inlet channel 61 and a water pump inlet pipe 62. There are two or more water pump inlet pipes 62, all of which are inserted into the right side of the inlet channel 61. The water pump inlet pipes 62 are interconnected with the cooling tower downcomer pipe 7 through the inlet channel 61.

[0041] It should be noted that the inlet channel 61 and the water pump inlet pipe 62 form a horizontal and vertical three-dimensional spatial arrangement of pipes under the cooling tower downpipe 7, which are interconnected to facilitate the circulation of water. This increases the number of circulating water pipe structures, promoting the flow and discharge of wastewater for recycling in the waste treatment plant.

[0042] During the wastewater recycling process at the waste treatment plant, staff activate valve 3 to connect the drainage channel 2 and the sewage pipe 4. The wastewater undergoes initial purification via a shallow sand filter 1. Chemical reagents are added through the feed inlet 11 to the shallow sand layer inside the filter tank 12 for calcification treatment, stabilizing the purified water. Staff can observe the purified water status through the observation window 13 and discharge sludge by opening the outlet 14. The water is then connected to the water tank 8 via a level control device 5. The circulating water pre-installed pipe 6 and the cooling tower downcomer 7 are additional circulating water pipes added to the waste treatment plant. The water storage tank 51 and water pump 52 are activated to connect to the condenser 53 and the condenser 54, allowing the incoming water to flow through. Wastewater from the waste treatment plant is introduced through the inlet channel 61 and the water pump inlet pipe 62. In the second step of the water purification cycle, the wastewater is circulated through the top opening trough 511 and the inner storage tank 513, and the connecting pipe 541 is used to connect the condensate tank 542 with the inner storage tank 513 to form a water level connection. Both the condensate tank 542 and the inner storage tank 513 are equipped with float control valves 514. When the equipment overflows, the damping constriction 512 holds the top opening trough 511 and the inner storage tank 513 under pressure, damping the unloaded water pressure and improving the overall wastewater recycling rate of the waste treatment plant. After purification, the water is circulated through the pre-reserved circulating water pipe 6 and the cooling tower downcomer pipe 7 to the water tank 8 for use by the waste treatment plant.

[0043] By expanding the water storage tank 8 and adding a level control device 5, as well as increasing the circulating water reserved pipe 6 and the cooling tower downcomer pipe 7 (i.e., the circulating water connection pipe), the number of water tanks 8 in the waste treatment plant is increased and the capacity is expanded through multiple pipe connections. When the water pump 52 has excessive pumping power, there is sufficient water supply in the water storage tank 51 and the water tank 8, avoiding the occurrence of vacuum phenomena. This has no impact on the condenser 54 for wastewater recycling in the waste treatment plant, stabilizing the smooth flow of condenser 54 for recycling and reuse. The level control between the water pump 52 and the water tank 8 is balanced and there is no overflow or backflow through the float control valve 514. At the same time, it can reduce the previous manual handling and realize the detection and control of condensate recycling through online level control.

[0044] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the scope of protection of the present application.
