Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to an anti-overflow structure for water treatment tanks. Background Technology

[0002] Steel plants require a large amount of cooling water during steelmaking operations. After use, this water needs to be filtered and recycled. The cooling water enters a treatment tank for filtration and is then transported through pipelines to a water tank for storage. The stored filtered water is used for subsequent cooling operations. As the filtered cooling water continuously flows into the water tank, overflow can easily occur if the filtered water in the tank is not discharged. Since water tanks are generally not made of transparent materials, staff cannot directly observe the water level inside the tank during routine inspections. This means that if a water tank overflows, staff can only respond hastily. Some water tanks are equipped with level sensors. Although these sensors have the function of monitoring the water level, once an alarm is triggered, they will control the water in the tank to be discharged. The discharged cooling water is directly discharged into the sewage pipe, which also easily leads to the waste of cooling water. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-overflow structure for water treatment tanks, thereby effectively solving the deficiencies in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water treatment tank anti-overflow structure, including a tank body, an inlet connector pipe, an anti-overflow pipe, and a drain connector pipe on the tank body. A water pump is installed on the anti-overflow pipe, and the other end of the anti-overflow pipe extends into the water treatment tank. A liquid level monitoring box is installed on one side of the tank body, and the liquid level monitoring box is connected to the tank body. A float that can rise and fall with the liquid level is installed inside the liquid level monitoring box. A window for observing the float is provided on the side of the liquid level monitoring box away from the tank body. The window is arranged vertically on the liquid level monitoring box and is at the same height as the inner cavity of the liquid level monitoring box. An observation glass is installed at the window. A sensor is installed on the top of the liquid level monitoring box, and an alarm is also installed on the top of the tank body. The float contacts the sensor to control the water pump to start and activate the alarm.

[0005] Furthermore, the bottom of the liquid level monitoring box has a first opening on the side facing the water tank body, and the bottom of the water tank body has a second opening at the position corresponding to the first opening. The first opening and the second opening cooperate with each other to form a water passage.

[0006] Furthermore, the float includes a buoy, and a sensing block is provided on the top of the buoy, the width of which is greater than the diameter of the buoy.

[0007] Furthermore, the sensor is a proximity switch, and the sensing end of the proximity switch is installed inside the liquid level monitoring box.

[0008] Furthermore, a manhole is provided on the top of the water tank body.

[0009] Furthermore, the manhole is equipped with an openable and closable cover.

[0010] Furthermore, the water inlet connector pipe is located at the upper end of the water tank body, the overflow prevention pipe is located in the middle of the water tank body, and the drain connector pipe is located at the lower end of the water tank body.

[0011] The above-mentioned technical solution of this utility model has the following beneficial effects: By setting a liquid level monitoring box on one side of the water tank body, and setting a float, sensor and window on the liquid level monitoring box, the staff can observe the position of the float through the window during inspection, thereby grasping the real-time water level in the water tank and having sufficient time to take countermeasures. Once the liquid level in the water tank body rises sharply, the sensor will be triggered, the reactor will start the water pump on the overflow pipe and send the cooling water in the water tank back to the water treatment tank. In this way, the overflow pipe makes the water treatment tank and the water tank body form a circulation, which can not only effectively control the liquid level in the water tank body, but also avoid the waste of cooling water discharge.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0016] like Figure 1-2As shown, the water treatment tank overflow prevention structure described in this embodiment includes a tank body 1. The tank body 1 is equipped with an inlet pipe 2, an overflow prevention pipe 3, and a drain pipe 4. The water supply pipe of the water treatment tank is connected to the inlet pipe 2. A circulation pipe is installed on the drain pipe 4, which re-transports the cooling water in the tank body 1 back to the equipment for cooling. A water pump 5 is installed on the overflow prevention pipe 3, and the other end of the overflow prevention pipe 3 extends into the water treatment tank. A liquid level monitoring box 6 is installed on one side of the tank body 1, and the liquid level monitoring box 6 is connected to the tank body. 1. A float 7 that can rise and fall with the liquid level is installed inside the liquid level monitoring box 6. A window for observing the float 7 is provided on the side of the liquid level monitoring box 6 away from the water tank body 1. The window is arranged vertically on the liquid level monitoring box 6 and is at the same height as the inner cavity of the liquid level monitoring box 6. An observation glass 8 is provided at the window. Preferably, the observation glass 8 is plexiglass. A sensor 9 is provided on the top of the liquid level monitoring box 6. An alarm 10 is also provided on the top of the water tank body 1. When the float 7 contacts the sensor 9, it controls the water pump 5 to start and activates the alarm 10.

[0017] The bottom of the liquid level monitoring box 6 has a first opening 6a on the side facing the water tank body 1, and the bottom of the water tank body 1 has a second opening 1a at the position corresponding to the first opening 6a. The first opening 6a and the second opening 1a cooperate to form a water passage.

[0018] The float 7 includes a float 7a, and a sensing block 7b is provided on the top of the float 7a. The width of the sensing block 7b is greater than the diameter of the float 7a, and the size of the sensing block 7b is slightly smaller than the inner cavity of the liquid level monitoring box 6. The entire float 7 is confined within the liquid level monitoring box 6 to ensure that the sensing block 7b is always located at the top.

[0019] Sensor 9 is a proximity switch, and the sensing end of the proximity switch is installed inside the liquid level monitoring box 6.

[0020] A manhole is provided on the top of the water tank body 1.

[0021] The manhole is equipped with an openable cover plate 11.

[0022] The inlet pipe 2 is located at the upper end of the water tank body 1, the overflow pipe 3 is located in the middle of the water tank body 1, and the drain pipe 4 is located at the lower end of the water tank body 1.

[0023] The working principle of this utility model is as follows: After the cooling water in the water treatment tank is treated, it is transported to the water tank body 1 through the water supply pipe and the water inlet connector pipe 2. The circulating water is stored in the water tank body 1 and the water level rises accordingly. Since the water tank body is connected to the liquid level monitoring box 6, the liquid level in the liquid level monitoring box 6 will also rise accordingly. During the inspection, the staff can observe the position of the float 7 through the observation glass 8 to monitor the liquid level in the water tank body 1. For easy observation, the float 7 can be set to an easily noticeable color. When the liquid level in the water tank body 1 rises continuously and reaches a high point, the float 7 will rise along with the liquid level, and the sensing block 7b on the float 7 will contact the top of the liquid level monitoring box 6. When sensor 9 in the part comes into contact, sensor 9 triggers a signal and controls alarm 10 to work. Sensor 9 also controls water pump 5 on overflow pipe 3 to start. Water pump 5 pumps out the water in water tank 1. The pumped circulating water flows back into water treatment tank through overflow pipe 3. At this time, a water circulation is formed between water tank 1 and water treatment tank, so that the water level in water tank 1 will not continue to rise. The circulating water discharged from water tank 1 enters water treatment tank to avoid waste of circulating water. When the circulating water in water tank 1 is used, the water level will drop. At this time, float 7 also separates from sensor 9. At this time, water pump 5 and sensor 10 are turned off, and circulating water is discharged through drain connector pipe 4 for use.

[0024] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
