Description
TECHNICAL FIELD
[0001] The application relates to the technical field of a vacuum pump station sewage discharge system, in particular to a vacuum tank of a vacuum pump station sewage discharge system with a radar liquid level detection device. BACKGROUND
[0002] The vacuum pump station sewage discharge system is mainly composed of a vacuum pump station, a vacuum pipeline, a vacuum interface unit and other auxiliary equipment, wherein the vacuum pump station is the core part of the system and is responsible for generating and maintaining the vacuum degree in the pipeline, thereby driving the sewage to flow in the pipeline.
[0003] With the acceleration of industrialization, the vacuum pump station is increasingly widely applied in various industrial productions. The sewage discharge system of the vacuum pump station is an important part for ensuring the clean and safe production environment. In order to effectively manage the liquid in the vacuum tank, the traditional liquid level monitoring technology mainly adopts the float ball type liquid level meter. The liquid level measurement is realized by the up-and-down movement of the float ball with the change of the liquid level. The technology has the characteristics of low cost and simple structure.
[0004] The float ball type liquid level meter is easily affected by pollutants, resulting in an increase in measurement error, especially in the high-viscosity and strong-corrosive liquid environment. The specific solutions of the prior art are as follows: one is to regularly clean the float ball to reduce the influence of dirt adhesion on the measurement result, but this increases the maintenance cost; the other is to adopt a double-float ball or multi-float ball design to improve the reliability of measurement through the comprehensive judgment of multiple float balls. Although this method improves the measurement accuracy, it also increases the complexity and failure rate of the equipment. The third is to introduce a capacitive or ultrasonic liquid level meter as an alternative solution. These two methods can overcome the problems of the float ball type liquid level meter to a certain extent, but they still have limitations in dealing with complex liquid conditions. CONTENT OF THE INVENTION

[0008] Further, the radar liquid level meter selects a non-contact GHz high-frequency radar sensor suitable for corrosive media.

[0013] Through the above scheme, the backlight technology provides sufficient light for the LCD display screen, so that the screen can produce high-brightness images, and even in a relatively dark environment, the screen can still display clearly. At the same time, the viewing angle of the LCD display screen is relatively large, and even when observed from the side, the image quality can still be maintained.
[0014] Further, the inner wall and outer surface of the tank body are subjected to rust-proof treatment.
[0015] Through the above scheme, the outer surface of the tank body is exposed to the natural environment for a long time and will be eroded by oxygen, moisture, ultraviolet rays and other factors. The outer surface rust-proof treatment can resist the erosion of these corrosive media and protect the tank body from damage.
[0016] Further, the upper surface of the bracket is provided with a gantry, and the upper end of the gantry is provided with a monitoring module.
[0017] Through the above scheme, the monitoring module can monitor the running state of the equipment in real time, including temperature, pressure, flow, vibration and other key parameters. When the equipment parameters exceed the preset range, the monitoring module can timely send an early warning signal to remind the operator to take measures to prevent faults from occurring or expanding.
[0018] Further, the bottom surface of the bracket is provided with a plurality of universal wheels, and the plurality of universal wheels are distributed in a matrix.
[0019] Through the above scheme, the universal wheel can rotate freely in horizontal and vertical directions, so that the moving direction of the support can be easily changed, and the universal wheel can provide excellent flexibility whether in a narrow space or in an environment where the direction needs to be frequently changed.
[0020] Further, the upper surface of the support is threadedly connected with two threaded rods, and the bottom ends of the two threaded rods are rotationally connected with resistance plates.
[0021] Through the above scheme, the resistance plate can increase the resistance between the support and the ground during installation, thereby improving the stability of the support and enabling it to stably support the tank body.
[0022] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 Please refer to Figure 1 、 Figure 2 The inner wall and the outer surface of the tank body 1 are subjected to rust-proof treatment.

[0034] The vacuum pump station blowdown system vacuum tank with a radar liquid level detection device in the embodiment realizes real-time and accurate monitoring of the liquid level in the tank by installing the radar liquid level meter 2 on the top of the vacuum tank and using advanced non-contact measurement technology and efficient data processing algorithm.

Users can flexibly configure various parameters according to actual needs to realize efficient management and maintenance of the vacuum pump station blowdown system.
[0035] The working principle of the above embodiment is that when the liquid level in the tank body 1 rises, the microwave signal emitted by the radar liquid level meter 2 is reflected back to the receiver by the water surface, and the actual liquid level height is calculated according to the round-trip time of the signal. After the signal processing unit 7 receives this data, it is converted into a digital signal and transmitted to the display module 4 through the communication interface. If the liquid level reaches the set upper or lower limit, the control system will start the corresponding alarm mechanism and adjust the working state of the control pump 6 to maintain the stability of the liquid level in the tank. By installing the radar liquid level meter 2 on the top of the vacuum tank, using advanced non-contact measurement technology and efficient data processing algorithm, real-time and accurate monitoring of the liquid level in the tank body 1 is realized. The selection of the radar liquid level meter 2 fully considers the characteristics of the industrial environment, adopts corrosion-resistant design, and can operate stably for a long time in harsh conditions. The whole system is composed of a signal processing unit 7, a display module 4 and a control system, which work together to not only improve the measurement accuracy but also enhance the intelligent level of the system. Users can flexibly configure various parameters according to actual needs to achieve efficient management and maintenance of the vacuum pump station sewage system. In this process, the monitoring module 9 can monitor the operating state of the equipment in real time, including temperature, pressure, flow, vibration and other key parameters. When the equipment parameters exceed the preset range, the monitoring module 9 can send an early warning signal in time to remind the operator to take measures to prevent faults from occurring or expanding. The radar liquid level meter 2 uses high-frequency electromagnetic waves, and the sensor can provide very accurate measurement data. At the same time, the sensor does not need to be in direct contact with the measured object, avoiding wear, pollution or damage caused by contact. It is suitable for measuring corrosive, viscous, high-temperature or explosive substances that are difficult to contact. The placement of the resistance plate 12 can increase the resistance between the placement bracket 5 and the ground during the placement process, thereby improving the stability of the bracket 5 and enabling it to stably support the tank body 1.
