Description

Technical Field

[0001] This utility model relates to an anti-clogging pressure transmitter. Background Technology

[0002] Pressure transmitters are key sensor devices in industrial automation, primarily used to accurately measure the pressure of fluids or gases and convert it into a standard electrical signal output. This facilitates real-time data acquisition and control by monitoring systems. They are widely used in industries such as petroleum, chemical, and power to ensure process safety and operational efficiency. The core of this device lies in its ability to provide stable and reliable pressure feedback; however, its long-term performance can be challenged in environments containing impurities or high-viscosity media.

[0003] Current pressure transmitter technology still has shortcomings: when measuring media that are prone to scaling or contain particulate matter, traditional equipment lacks an effective anti-clogging mechanism, leading to rapid clogging of the filter, decreased measurement accuracy, and even equipment failure; the structural design is often bulky, and the maintenance access is poorly designed, making cleaning and maintenance work cumbersome and time-consuming; at the same time, most transmitters lack integrated flow rate monitoring functions, making it impossible to provide real-time warnings of clogging risks, thereby increasing maintenance costs and downtime risks, and affecting the continuous operation of the overall system. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging pressure transmitter to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An anti-clogging pressure transmitter includes an inlet pipe, a fixed flange, a display head, a control panel, an output pipe, and an anti-clogging structure. The fixed flange is installed on the top of the inlet pipe, the display head is installed on the top of the fixed flange, the control panel is located on the front of the display head, the output pipe is fixedly connected to the left side of the display head, and the anti-clogging structure is installed between the display head and the output pipe.

[0006] Based on the above technical solution, the anti-clogging structure includes an anti-clogging pipe, an air supply pipe, and a micro air pump. The top of the anti-clogging pipe is fixedly connected to the air supply pipe, and the micro air pump is installed on the top of the air supply pipe.

[0007] Based on the above technical solution, the anti-clogging pipe includes a pipe body, a wire connecting plate, a filter screen, and a flow rate sensor. The wire connecting plate is fixedly connected to the left side of the pipe body, and the two filter screens are fixedly connected to the inside of the pipe body. The flow rate sensor is installed between the two filter screens and the wire connecting plate.

[0008] Compared with the prior art, the present invention has the following advantages: The advantage of the present invention lies in the overall optimization of the anti-clogging design. By integrating the anti-clogging pipe, the air supply pipe and the micro air pump through the anti-clogging structure, the automatic cleaning function is realized. Combined with the real-time monitoring of the filter screen and the flow rate sensor, the anti-clogging capability and measurement reliability of the equipment are significantly improved. At the same time, the display head and control dial facilitate operation and monitoring, and the fixed flange ensures stable installation, so that the equipment can maintain efficient and low-maintenance operation even under harsh working conditions.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-3 As shown, an anti-clogging pressure transmitter includes an inlet pipe 1, a fixed flange 2, a display head 3, a control dial 4, an output pipe 5, and an anti-clogging structure 6. The fixed flange 2 is installed on the top of the inlet pipe 1, the display head 3 is installed on the top of the fixed flange 2, the control dial 4 is opened on the front of the display head 3, the output pipe 5 is fixedly connected to the left side of the display head 3, and the anti-clogging structure 6 is installed between the display head 3 and the output pipe 5.

[0015] The anti-blocking structure 6 includes an anti-blocking pipe 7, an air supply pipe 8, and a micro air pump 9. The top of the anti-blocking pipe 7 is fixedly connected to the air supply pipe 8, and the micro air pump 9 is installed on the top of the air supply pipe 8.

[0016] The anti-clogging pipe 7 includes a pipe body 10, a wire connecting plate 11, a filter screen 12, and a flow rate sensor 13. The wire connecting plate 11 is fixedly connected to the left side of the pipe body 10, and the two filter screens 12 are fixedly connected to the inside of the pipe body 10. The flow rate sensor 13 is installed between the two filter screens 12 and the wire connecting plate 11.

[0017] The working principle of this utility model is as follows: First, the medium to be measured is introduced through the inlet pipe 1. Then, the fixed flange 2 fixes the device to the installation point, and the display head 3 displays the real-time pressure data through the control dial 4. Next, the medium flows through the anti-clogging structure 6, in which the filter screen 12 in the anti-clogging pipe 7 performs preliminary filtration, and the flow rate sensor 13 monitors the flow rate change. If signs of blockage are detected, the micro air pump 9 injects gas through the air supply pipe 8 for backflushing and cleaning. Finally, the cleaned pressure signal is stably output through the output pipe 5 to ensure that the entire measurement process is continuous and accurate.

[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
