Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of storage tanks, and more specifically, to a storage tank with a function of removing scum. Background Technology

[0002] In the field of wastewater treatment, wastewater storage tanks are indispensable storage equipment. During actual operation, when wastewater enters the tank, the impact caused by factors such as flow velocity and drop creates a large amount of foam on the surface of the wastewater. The presence of this foam seriously affects the normal operation of the storage tank and monitoring work.

[0003] On the one hand, the presence of a foam layer can interfere with the accurate detection of wastewater level. Traditional level detection devices, such as ultrasonic level gauges and radar level gauges, work by emitting signals and receiving reflected signals to calculate the level. However, the loose structure and irregular surface of the foam layer can cause scattering and refraction of the detection signal, leading to inaccurate signal reception and significant deviations in the level detection results. This makes it impossible to provide reliable data support for wastewater treatment processes, affecting the precise control and management of subsequent wastewater treatment procedures.

[0004] On the other hand, the long-term accumulation of large amounts of scum inside wastewater storage tanks may cause overflows, resulting not only in environmental pollution but also potentially affecting the normal operation of surrounding equipment. Furthermore, the scum may absorb pollutants from the wastewater, forming difficult-to-treat mixtures and increasing the difficulty and cost of wastewater treatment. However, most existing wastewater storage tanks lack effective scum removal devices, failing to meet the demands of actual wastewater treatment processes. Therefore, developing a storage tank capable of effectively removing scum and ensuring accurate liquid level detection is of significant practical importance. Utility Model Content

[0036] like Figures 1-6 As shown, it illustrates a storage tank with a scum removal function according to an embodiment of the present disclosure, comprising:

[0037] The tank body 1 and the top cover 2, wherein the top cover 2 is disposed on the top of the tank body 1;

[0038] Discharge assembly 6 is disposed at the bottom of the tank body 1;

[0039] The ultrasonic sensor 3, the controller 4, and the cleaning component 5 are provided. The ultrasonic sensor 3 and the controller 4 are both disposed on the top cover 2, and the cleaning component 5 is disposed in the top cover 2.

[0040] The cleaning component 5 includes a rectangular cover 5-1, which is disposed on the surface of the top cover 2 and extends into the interior of the tank 1. A movable column 5-2 is movably fitted inside the rectangular cover 5-1. The movable column 5-2 has a hollow internal structure, and a fixed sleeve 5-3 is provided at the lower end of the movable column 5-2. A collection cover 5-4 is rotatably fitted onto the fixed sleeve 5-3. Side grooves 5-5 are provided on both sides of the collection cover 5-4, and several suction ports 5-6 are provided within the side grooves 5-5. A drive motor 5-7 is provided at the lower outer side of the rectangular cover 5-1, and the output end of the drive motor 5-7 is... The top cover 2 is equipped with a drive wheel 5-8 and a transmission wheel 5-9. The drive wheel 5-8 and the transmission wheel 5-9 are connected by a belt drive. The top cover 2 is equipped with a drive motor 5-10. The output end of the drive motor 5-10 is equipped with a shaft disc 5-11. The top of the rectangular cover 5-1 is equipped with a pulley 5-12. The upper end of the movable column 5-2 is connected to the shaft disc 5-11 by a cable 5-13. The cable 5-13 is laid on the upper end of the pulley 5-12. The top cover 2 is fitted with a connecting cover 5-14. The ultrasonic sensor 3 is installed in the connecting cover 5-14.

[0041] In some examples, during the use of the storage tank, in order to effectively remove the foam generated on the surface of the liquid inside the tank and to adaptively adjust according to the foam height, a removal component 5 is designed. This component includes a rectangular cover 5-1 set on the surface of the top cover 2 and extending into the interior of the tank body 1, providing installation and movement space for components such as the movable column 5-2. The movable column 5-2, which is movably fitted inside the rectangular cover 5-1, has an internal cavity structure that can be connected to a suction device for transferring the collected foam. A fixed sleeve 5-3 is set at the lower end of the movable column 5-2, on which a collection cover 5-4 is rotatably fitted. The key component for achieving foam collection includes several suction ports 5-6 distributed within the side grooves 5-5 on both sides of the collection hood 5-4, which can draw foam into the collection hood 5-4. A drive motor 5-7 is located at the lower outer side of the rectangular cover 5-1, and its output drive wheel 5-8 is connected to the transmission wheel 5-9 located at the upper end of the collection hood 5-4 via a belt drive. When the drive motor 5-7 starts, the drive wheel 5-8 drives the transmission wheel 5-9 to rotate, causing the collection hood 5-4 to rotate and expanding the foam collection area. A drive motor 5-10 is located on the surface of the top cover 2, and its output shaft disc 5-11 is connected to the top cover 2 via a cable. Rope 5-13 is connected to the upper end of movable column 5-2. Rope 5-13 rests on pulley 5-12 at the top of rectangular cover 5-1. When drive motor 5-10 operates, it retracts or extends rope 5-13 via shaft disc 5-11, causing movable column 5-2 to move up and down within rectangular cover 5-1. Ultrasonic sensor 3, installed on the surface of top cover 2 and inside connecting cover 5-14, uses an ultrasonic EV meter to detect the height of sewage in the tank in real time and transmits the data to controller 4. Controller 4 controls drive motor 5-10 to adjust the position of movable column 5-2 based on the water level, causing collection cover 5-4 to start... The system is designed to remove scum at the highest water level, effectively preventing excessive scum from affecting liquid level detection. Through the coordinated work of components such as rectangular cover 5-1, movable column 5-2, fixed sleeve 5-3, collection cover 5-4, side groove 5-5, suction port 5-6, drive motor 5-7, drive wheel 5-8, transmission wheel 5-9, belt, drive motor 5-10, shaft disc 5-11, pulley 5-12, cable 5-13, connecting cover 5-14, and ultrasonic sensor 3, the scum removal component 5 can accurately remove scum and automatically adjust its working position according to the water level to ensure that there is no scum in the storage tank.

[0042] like Figures 1-6 As shown in the figure, the discharge assembly 6 in this embodiment includes a discharge pipe 6-1, one end of which is connected to a drive screw 6-2 by a threaded connection, and a sealing block 6-3 is provided inside the discharge pipe 6-1. One end of the drive screw 6-2 is rotatably connected to the sealing block 6-3.

[0043] In some examples, during the wastewater treatment process in storage tanks, a discharge assembly 6 is designed to achieve precise control over the discharge of wastewater from the tank. This assembly includes a discharge pipe 6-1 with one end connected to a drive screw 6-2 via a threaded connection. The discharge pipe 6-1 serves as a channel for wastewater discharge. A sealing block 6-3 installed inside the discharge pipe 6-1 can tightly seal the pipe to prevent wastewater leakage when no discharge operation is being performed. When discharge is required, the drive screw 6-2 is rotated. Since one end of the drive screw 6-2 is rotatably connected to the sealing block 6-3, the rotational motion of the screw is converted into the rotational motion of the sealing block. The linear motion of 6-3 causes the sealing block 6-3 to move axially along the discharge pipe 6-1, thereby opening the pipe. Sewage flows out through the discharge pipe 6-1 under the action of gravity or pressure. By adjusting the rotation degree of the drive screw 6-2, the moving distance of the sealing block 6-3 can be controlled, thereby adjusting the size of the discharge port and achieving precise control of the discharge speed and discharge volume. Through the coordinated work of components such as the discharge pipe 6-1, drive screw 6-2, and sealing block 6-3, the discharge assembly 6 can stably and reliably control the discharge process of the storage tank and meet the sewage transportation needs under different working conditions.

[0044] For example, such as Figure 1 As shown, the top cover 2 has several outer grooves 7 on its surface, and bolts 8 are installed in the outer grooves 7. The bolts 8 are connected to the top of the tank body 1 by screwing.

[0045] In some examples, the top cover 2 can be tightly fixed to the top of the tank body 1 by providing an outer groove 7 and bolts 8, and can be disassembled for easy internal cleaning.

[0046] For example, such as Figure 6 As shown, the inner bottom surface of the side groove 5-5 is an inclined structural surface.

[0047] In some examples, by tilting the structural surface, the side groove 5-5 is made to act like a shovel, which can scoop up foam when rotating, making it easier to be sucked up.

[0048] For example, such as Figure 3 As shown, a sealing layer 9 is provided on the bottom surface of the top cover 2, and the sealing layer 9 is attached to the inner wall of the tank body 1.

[0049] In some examples, the sealing layer 9 is provided to increase the sealing effect between the top cover 2 and the tank body 1, thus preventing leakage.

[0050] For example, such as Figure 3 As shown, the length of the collection cover 5-4 matches the inner diameter of the tank 1.

[0051] In some examples, by matching the size and coordinating rotation, all the foam can be collected effectively, resulting in excellent performance.

[0052] In actual use: First, fix the top cover 2 to the top of the tank 1 with bolts 8. Use the sealing layer 9 to ensure the sealing of the tank 1. During the operation of the storage tank, the ultrasonic sensor 3 monitors the sewage height in real time and transmits the data to the controller 4. The controller 4 controls the drive motor 5-10. Adjust the height of the movable column 5-2 and the collection cover 5-4 through the shaft disc 5-11 and the cable 5-13. Start the drive motor 5-7. The drive wheel 5-8 drives the transmission wheel 5-9 to rotate the collection cover 5-4. Collect the foam through the side groove 5-5 and the suction port 5-6 with the suction equipment. The collected foam is discharged through the cavity of the movable column 5-2. When it is necessary to discharge the sewage in the tank, rotate the drive screw 6-2. The drive screw 6-2 drives the sealing block 6-3 to move. Open the discharge pipe 6-1 to discharge the material.
