Technical Field
[0001] This utility model relates to the field of wastewater recycling technology, specifically a wastewater recycling device. Background Technology
[0002] Industrial wastewater treatment is a major environmental challenge. Industrial wastewater is produced in large quantities and is difficult to collect and store. Existing treatment methods usually involve collecting the wastewater and then treating it in a special place, which is inconvenient to operate. In order to meet market needs, a wastewater recycling device is required.
[0003] Existing wastewater recovery devices are inconvenient to operate during maintenance and repair. Moreover, they typically cannot automatically detect the liquid level during use, which prevents them from automatically controlling the start or stop of the stainless steel centrifugal pump. This also means that the devices cannot provide water shortage protection or prevent overflow when the storage tank is full. In addition, existing wastewater recovery devices usually lack anti-vacuum functions, which can easily lead to a vacuum inside the storage tank during use, resulting in internal pressure preventing water from entering. Utility Model Content
[0004] The purpose of this invention is to provide a wastewater recycling device to solve the problems mentioned in the background art, such as the inability of wastewater recycling devices to automatically detect liquid levels and the lack of anti-vacuum function.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater recycling device, comprising a device frame, with a storage tank installed inside the device frame. A mounting base is installed on the top surface of the storage tank via screws. A controller is installed on the surface of the device frame, and an indicator light is installed on the surface of the controller. A stainless steel centrifugal pump is installed on the top surface of the mounting base. The input end of the stainless steel centrifugal pump is electrically connected to the output end of the controller. A water outlet pipe is provided at the output end of the stainless steel centrifugal pump. A liquid level detection mechanism is provided on the surface of the storage tank, and an anti-vacuum mechanism is provided on the surface of the storage tank.
[0006] Preferably, the outlet pipe is connected to the interior of the stainless steel centrifugal pump, the output end of the stainless steel centrifugal pump passes through the liquid storage tank and extends into the interior of the liquid storage tank, the outlet pipe and the output end of the stainless steel centrifugal pump are fitted with a mounting flange, the surface of the outlet pipe is fitted with a valve, and the input end of the valve is electrically connected to the output end of the controller.
[0007] Preferably, the anti-vacuum mechanism consists of an exhaust pipe, an exhaust valve, an air outlet pipe, and mounting bolts. The surface of the liquid storage tank is provided with an exhaust pipe, the bottom end of which penetrates the liquid storage tank and extends into the interior of the liquid storage tank. The surface of the exhaust pipe is threaded with mounting bolts, and the input end of the mounting bolts is electrically connected to the output end of the controller.
[0008] Preferably, an exhaust valve is fitted on the surface of the exhaust pipe, the input end of the exhaust valve is electrically connected to the output end of the controller, and an exhaust pipe is installed on the surface of the exhaust valve, which is connected to the interior of the exhaust pipe.
[0009] Preferably, the liquid level detection mechanism consists of a liquid level tube, a fixed tube, a hole, a liquid level sensor, and a liquid level detection switch. A liquid level tube is installed on one side of the liquid storage tank. Holes are opened on the surface of the liquid storage tank. A fixed tube is installed on the surface of the liquid level tube. One end of the fixed tube passes through the hole and extends into the interior of the hole. The hole is connected to the interior of the liquid level tube.
[0010] Preferably, a liquid level detection switch is installed on the surface at the top of the liquid storage tank, and a liquid level sensor for monitoring the liquid level is installed on the inner wall of the liquid storage tank. The input terminal of the liquid level sensor is electrically connected to the output terminal of the controller.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the wastewater recycling device can not only automatically control the start or stop of the stainless steel centrifugal pump when the recycling device is in use, and can protect the inside of the storage tank from water shortage and prevent overflow when the tank is full, but also prevent the phenomenon of vacuuming or internal pressure preventing water from entering the storage tank when the recycling device is in use.
[0012] 1. By setting up a liquid level detection mechanism, wastewater inside the storage tank enters the liquid level tube through a fixed pipe, making the water level inside the liquid level tube the same as the water level inside the storage tank. When the user turns on the liquid level detection switch, when the water level inside the storage tank is too high, the liquid level sensor senses the excessive water level and sends a signal to the controller. At this time, the controller receives the signal from the liquid level sensor and automatically controls the stainless steel centrifugal pump to shut down, preventing wastewater from continuing to enter the storage tank. When the water level inside the storage tank decreases, the controller controls the stainless steel centrifugal pump to turn on, allowing wastewater to continue entering the storage tank. This avoids the phenomenon of too little or too much water in the storage tank, realizing the function of automatic liquid level detection of the recycling device. Thus, the recycling device can automatically control the start or stop of the stainless steel centrifugal pump during use, enabling the recycling device to protect the storage tank from water shortage and prevent overflow when full.
[0013] 2. Equipped with an anti-vacuum mechanism, the user places the exhaust pipe on the surface of the top of the storage tank, allowing one end of the exhaust pipe to move into the interior of the tank. Then, the mounting bolts on the exhaust pipe surface are tightened to install the exhaust pipe onto the surface of the storage tank. The exhaust valve is a device used to maintain the pressure balance inside and outside the storage tank, preventing damage caused by overpressure or vacuum. The exhaust valve includes a pressure valve disc for exhalation and a vacuum valve disc for inhalation, allowing for flexible opening and closing during pressure changes. Specifically, the valve disc of the exhaust valve... The valve plate is tightly fitted to the valve seat under the action of the spring or its own gravity, ensuring that the gas in the storage tank does not leak. When the pressure in the storage tank rises to the set value, the gas pushes the valve plate to overcome the spring resistance or gravity, causing the exhaust valve to open and the gas to be discharged from the storage tank, preventing overpressure in the storage tank. When the pressure in the storage tank drops to the set value, the external atmosphere pushes open the negative pressure valve plate, and the gas enters the storage tank, preventing vacuum. This realizes the anti-vacuum function of the recovery device, thus preventing the phenomenon of vacuum or internal pressure preventing water from entering the storage tank when the recovery device is used.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0020] The structure of the wastewater recycling device provided by this utility model is as follows: Figure 1 and Figure 2 As shown, the device includes a frame 1, inside which a liquid storage tank 101 is installed. A mounting base 106 is screwed onto the top surface of the liquid storage tank 101. A controller 103 (e.g., LA series) is mounted on the surface of the frame 1. An indicator light is mounted on the surface of the controller 103. A stainless steel centrifugal pump 105 (e.g., SLG series) is mounted on the top surface of the mounting base 106. The input terminal of the stainless steel centrifugal pump 105 is electrically connected to the output terminal of the controller 103. The output end of the 105 is provided with a water outlet pipe 104, which is connected to the interior of the stainless steel centrifugal pump 105. The output end of the stainless steel centrifugal pump 105 passes through the liquid storage tank 101 and extends into the interior of the liquid storage tank 101. The water outlet pipe 104 and the output end of the stainless steel centrifugal pump 105 are fitted with a mounting flange 107. A valve 102 is fitted on the surface of the water outlet pipe 104. The input end of the valve 102 is electrically connected to the output end of the controller 103. The valve 102 can be of the TM series.
[0021] Furthermore, such as Figure 2 and Figure 3As shown, a liquid level detection mechanism 3 is provided on the surface of the liquid storage tank 101. The liquid level detection mechanism 3 consists of a liquid level tube 31, a fixed tube 32, a hole 33, a liquid level sensor 34, and a liquid level detection switch 35. A liquid level tube 31 is installed on one side of the surface of the liquid storage tank 101. Holes 33 are opened on the surface of the liquid storage tank 101. A fixed tube 32 is installed on the surface of the liquid level tube 31. One end of the fixed tube 32 passes through the hole 33 and extends into the interior of the hole 33. The hole 33 is connected to the interior of the liquid level tube 31. A liquid level detection switch 35 is installed on the surface at the top of the liquid storage tank 101. A liquid level sensor 34 for monitoring the liquid level is installed on the inner wall of the liquid storage tank 101. The model of the liquid level sensor 34 can be selected from the HPT series. The input terminal of the liquid level sensor 34 is electrically connected to the output terminal of the controller 103.
[0022] In practice, wastewater inside the storage tank 101 enters the liquid level pipe 31 through the fixed pipe 32, making the water level inside the liquid level pipe 31 the same as the water level inside the storage tank 101. When the user turns on the liquid level detection switch 35, when there is too much water inside the storage tank 101, the liquid level sensor 34 senses that there is too much water inside the storage tank 101 and sends a signal to the controller 103. At this time, the controller 103 receives the signal from the liquid level sensor 34 and automatically controls the stainless steel centrifugal pump 105 to shut down, so that wastewater cannot continue to enter the storage tank 101. When the water level inside the storage tank 101 decreases, the controller 103 controls the stainless steel centrifugal pump 105 to turn on, so that wastewater continues to enter the storage tank 101, avoiding the phenomenon of too little or too much water inside the storage tank 101, so as to realize the function of automatic liquid level detection of the recycling device.
[0023] Furthermore, such as Figure 2 and Figure 4 As shown, the surface of the liquid storage tank 101 is provided with an anti-vacuum mechanism 2. The anti-vacuum mechanism 2 consists of an exhaust pipe 21, an exhaust valve 22, an air outlet pipe 23, and mounting bolts 24. The surface of the liquid storage tank 101 is provided with an exhaust pipe 21. The bottom end of the exhaust pipe 21 penetrates the liquid storage tank 101 and extends into the interior of the liquid storage tank 101. The surface of the exhaust pipe 21 is threaded with mounting bolts 24. The input end of the mounting bolts 24 is electrically connected to the output end of the controller 103. The surface of the exhaust pipe 21 is fitted with an exhaust valve 22. The input end of the exhaust valve 22 is electrically connected to the output end of the controller 103. The surface of the exhaust valve 22 is installed with an air outlet pipe 23, which is connected to the interior of the exhaust pipe 21.
[0024] During implementation, the user places the exhaust pipe 21 on the surface of the top position of the liquid storage tank 101, causing one end of the exhaust pipe 21 to move into the interior of the liquid storage tank 101. Then, the user tightens the mounting bolts 24 on the surface of the exhaust pipe 21, thus installing the exhaust pipe 21 onto the surface of the liquid storage tank 101. The exhaust valve 22 is a device used to maintain the pressure balance inside and outside the liquid storage tank 101, preventing damage to the liquid storage tank 101 due to overpressure or vacuum. The exhaust valve 22 includes a pressure valve disc for exhalation and a vacuum valve disc for inhalation, allowing for flexible adjustment during pressure changes. The valve can be opened and closed as follows: the valve disc of the exhaust valve 22 is tightly fitted to the valve seat under the action of the spring or its own gravity to ensure that the gas in the liquid storage tank 101 does not leak. When the pressure in the liquid storage tank 101 rises to the set value, the gas pushes the valve disc to overcome the spring resistance or gravity, causing the exhaust valve 22 to open and the gas to be discharged from the liquid storage tank 101 to prevent overpressure. When the pressure in the liquid storage tank 101 drops to the set value, the external atmosphere pushes open the negative pressure valve disc and the gas enters the liquid storage tank 101 to prevent vacuum, so as to realize the function of preventing vacuum in the recovery device.
[0025] Working principle: In use, first push the device frame 1 to the designated position. The controller 103 controls the stainless steel centrifugal pump 105 to work, introducing wastewater through the outlet pipe 104 into the storage tank 101. Under the action of the storage tank 101, the wastewater is centrally recycled. The wastewater inside the storage tank 101 enters the liquid level pipe 31 through the fixed pipe 32, making the water level inside the liquid level pipe 31 the same as the water level inside the storage tank 101. The user turns on the liquid level detection switch 35. When the water level inside the storage tank 101 is too high, the liquid level sensor 34 senses that the water level inside the storage tank 101 is too high and sends a signal to the controller 103. At this time, The controller 103 receives the signal from the liquid level sensor 34 and automatically controls the stainless steel centrifugal pump 105 to shut down, preventing wastewater from continuing to enter the storage tank 101. When the water level inside the storage tank 101 decreases, the controller 103 controls the stainless steel centrifugal pump 105 to turn on, allowing wastewater to continue entering the storage tank 101. This prevents the storage tank 101 from having too little or too much water, thus enabling the recycling device to automatically detect the liquid level. This allows the recycling device to automatically control the start or stop of the stainless steel centrifugal pump 105 during use, providing water shortage protection and preventing overflow when the storage tank 101 is full.
[0026] Subsequently, the user places the exhaust pipe 21 on the surface of the top position of the liquid storage tank 101, causing one end of the exhaust pipe 21 to move into the interior of the liquid storage tank 101. Then, the user tightens the mounting bolts 24 on the surface of the exhaust pipe 21, installing the exhaust pipe 21 onto the surface of the liquid storage tank 101. The exhaust valve 22 is a device used to maintain the pressure balance inside and outside the liquid storage tank 101, preventing damage to the liquid storage tank 101 due to overpressure or vacuum. The exhaust valve 22 includes a pressure valve disc exhalation valve and a vacuum valve disc inhalation valve, allowing for flexible opening and closing during pressure changes. Specifically, the valve disc of the exhaust valve 22 is controlled by a spring or its own weight. Under the action of the valve seat, the gas in the storage tank 101 is tightly fitted to ensure that there is no gas leakage. When the pressure in the storage tank 101 rises to the set value, the gas pushes the valve disc to overcome the spring resistance or gravity, so that the exhaust valve 22 opens and the gas is discharged from the storage tank 101 to prevent overpressure. When the pressure in the storage tank 101 drops to the set value, the external atmosphere pushes open the negative pressure valve disc and the gas enters the storage tank 101 to prevent vacuum. This realizes the anti-vacuum function of the recovery device, so that the recovery device can prevent the phenomenon of vacuum or internal pressure preventing water from entering the storage tank 101 during use, and finally completes the use of the wastewater recovery device.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
