Description

Technical Field

[0001] This utility model belongs to the field of industrial production equipment technology, and specifically relates to an automatic water filling device for a washing tank. Background Technology

[0002] In numerous industrial production and daily application scenarios, washing tanks serve as key equipment, undertaking important tasks such as cleaning and diluting materials. The precise control of the water added directly affects the stability of the production process, product quality, and resource utilization efficiency.

[0003] Currently, water filling of washing tanks mainly relies on manual methods. Specifically, the operator must judge the water level inside the tank based on experience and manually control the start and stop of the water pump to add water. However, in actual operation, the large flow rate of water pumped into the washing tank presents a significant challenge to water level control. When the water level inside the tank gradually rises and approaches the predetermined height, the operator may fail to shut off the pump in time due to delayed reaction, operational negligence, or inaccurate judgment of the water level. If the pump fails to stop at the appropriate time, a large amount of water will continue to flow into the washing tank, causing the final water level inside the tank to exceed the predetermined level, resulting in excessive water addition.

[0004] Adding too much water can lead to a series of adverse consequences. In industrial production, it may affect the cleaning effect of materials, resulting in incomplete or excessive cleaning and reduced product quality; it may also waste water resources and increase production costs. In addition, for some processes with strict requirements on water volume, adding too much water may even cause safety accidents and threaten production safety.

[0005] Given the numerous drawbacks of manual water addition, it is essential and of great practical significance to design a device that can automatically and accurately control the amount of water added to the washing tank in order to achieve precise control of the water addition, improve the automation and stability of the production process, reduce the risk of human error, and reduce water waste. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides an automatic water filling device for a washing tank to solve the above problems.

[0017] To better understand this utility model, the embodiments of this utility model will be explained in detail below with reference to the accompanying drawings.

[0018] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0019] The automatic water filling device for the washing tank of this utility model includes a tank body 1, which serves as the core container of the entire device and is used to hold the materials to be cleaned and the water. The tank body 1 is provided with an inlet 2 and an outlet 3. The inlet 2 is used to add water into the tank body 1, and the outlet 3 is used to discharge the wastewater or materials after cleaning.

[0020] To achieve automated water filling control, a liquid level detection component 4 is installed on the tank 1. The liquid level detection component 4 includes a vertical pipe 7, the bottom of which is bent and connected to the bottom of one side of the tank 1. This connection method ensures that the water level in the vertical pipe 7 is consistent with the water level in the tank 1, accurately reflecting the liquid level in the tank 1. A hollow float 8 is inserted into the top of the vertical pipe 7, and the float 8 can float up and down with changes in the water level in the vertical pipe 7. The float 8 has several color segments of different colors, specifically red, yellow, and green segments, arranged sequentially from top to bottom on the float 8. The different colored segments provide clear indicators for the subsequent color sensor 9 to identify the liquid level height. A color sensor 9, which works in conjunction with the float 8, is installed at the top of the vertical pipe 7. The color sensor 9 can detect the color changes of the color segments on the float 8 in real time and transmit the detected color signal to the subsequent control unit.

[0021] A flow pump 5 is installed at the input port 2, which controls the flow rate and velocity of water added to the tank 1. A PLC control cabinet 6 is located on one side of the tank 1. The PLC control cabinet 6 serves as the control core of the entire device, connecting the flow pump 5 and the color sensor 9 in the liquid level detection assembly 4. When the color sensor 9 detects a specific color segment on the float 8, it transmits a signal to the PLC control cabinet 6. The PLC control cabinet 6 then determines, according to a preset program, whether the liquid level in the tank 1 has reached a predetermined height. If the predetermined height is reached, the PLC control cabinet 6 issues a command to stop the flow pump 5, thus automatically stopping the water addition.

[0022] To ensure stable water supply and balanced pressure, a pressure-stabilizing water tank 10 is installed on one side of the tank body 1. A water inlet pipe 11 is connected to the pressure-stabilizing water tank 10, and a flow pump 5 is installed on the water inlet pipe 11 to pump water from the pressure-stabilizing water tank 10 into the tank body 1. The pressure-stabilizing water tank 10 also has a water inlet for replenishing water to the tank.

[0023] To facilitate observation of the liquid level inside tank 1, a viewing slot is provided on one side of the vertical pipe 7, and a transparent cover 12 is embedded in the viewing slot. The transparent cover 12 is equipped with scale lines. Operators can directly see the water level in the vertical pipe 7 through the transparent cover 12 and, in conjunction with the scale lines, more accurately understand the liquid level inside tank 1.

[0024] Considering that impurities in the water may affect the normal operation of the equipment, a quick-release filter 13 is installed between the vertical pipe 7 and the tank 1. The quick-release filter 13 can filter out impurities in the water, preventing them from entering the vertical pipe 7 and the liquid level detection component 4, thus affecting the floating of the float 8 and the detection accuracy of the color sensor 9. At the same time, the quick-release design makes cleaning and replacement of the filter more convenient and quick.

[0025] A conical flow deflector is installed at the top of the float 8, and the diameter of the flow deflector is greater than or equal to that of the vertical pipe 7. The function of the flow deflector is to prevent rainwater from entering the vertical pipe 7 along the float 8 when the equipment is placed outdoors, thereby reducing interference.

[0026] To ensure the stability of tank 1 during placement, several load-bearing legs are installed at the bottom of tank 1, and each load-bearing leg is equipped with an adjustable load-bearing seat 14 at its bottom. The adjustable load-bearing seat 14 can be adjusted according to the flatness of the ground to keep tank 1 level at all times, preventing tank 1 from tilting due to uneven ground and affecting the normal operation of the equipment.

[0027] The usage and principle of this utility model: When using the automatic water filling device for the washing tank, firstly, an appropriate amount of water is injected into the pressure-stabilizing water tank 10 through the water inlet. Then, the flow pump 5 is turned on, and water is delivered to the tank 1 through the water inlet pipe 11. As the water level in the tank 1 rises, the water level in the vertical pipe 7 also rises, and the float 8 floats upward under the action of buoyancy. The color sensor 9 detects the color change of the color segment on the float 8 in real time and transmits the signal to the PLC control cabinet 6. When the color sensor 9 detects the color of the color segment on the float 8 representing the predetermined liquid level height, the PLC control cabinet 6 issues a command to control the flow pump 5 to stop working, automatically stopping the addition of water to the tank 1. The operator can also visually observe the liquid level in the tank 1 through the scale lines on the viewing slot and transparent cover 12. During the operation of the equipment, the quick-release filter 13 filters the water to ensure the normal operation of the equipment. If the ground is uneven, the tank 1 can be kept level by adjusting the support base 14. The entire water-addition process is automated and precisely controlled, effectively avoiding the problem of excessive water addition caused by untimely manual operation.
