Description

Technical Field

[0001] The invention relates to the technical field of pipeline blockage blowing, in particular to a portable sampling pipe blockage clearing device. Background Art

[0002] In thermal power generation and other production enterprises, it is usually necessary to measure the pressure, flow rate, flow rate and other physical quantities of the medium in the process pipeline through a sampling tube to realize the monitoring and control of the process flow. For the medium containing dust particles, some dust particles may be deposited at the mouth of the sampling tube or the bend of the sampling tube during long-term operation, thereby blocking the sampling tube and affecting normal measurement. The deposited dust particles will further solidify when encountering water vapor, completely blocking the sampling tube. Usually, when dealing with this kind of fault, it is necessary to lead a compressed air to purge the sampling tube, or add an automatic purge device. This requires that the compressed air pipelines at the production site are spread across various sampling points, which will greatly increase the production cost. Sometimes there is a lot of water inside the compressed air pipeline that has not been used for a long time. When it is used, it needs to be drained for a long time. If the accumulated water is not drained before purge, it will further aggravate the blockage. In some small production enterprises, there is not even a fixed air compressor that runs continuously, and it is very inconvenient to use a mobile air compressor for purge. Summary of the invention

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0021] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, and provides a portable sampling tube blockage clearing device, wherein the control component 100 includes a controller 101 and a touch screen 102 electrically connected to the controller 101. When the entire device is working, the control component 100 is convenient for the staff to set specific processing values, and collects and processes the environmental data during work through computers, sensors and other components, and releases instructions to ensure the normal operation of the device; and, the air supply component 200 includes an air compression part 201 and an air release part 204 arranged on the side of the air compression part 201. The air compression part 201 can absorb external air, filter impurities and moisture contained in the air, and then compress the air and send the compressed air to the air release part 204. When the internal pressure of the air release part 204 reaches the set value, the pressure is released, and the blockage is reopened by the pressure of the compressed air to complete the cleaning.

[0022] Specifically, when the user sets the target compressed air pressure through the touch screen and starts compression, the data is transmitted to the inside of the controller 101, and the control sends a start instruction to continuously use the air compression part 201 to compress the air and discharge the compressed air to the air release part 204. When the detected pressure reaches the set target compressed air pressure value, the air compression part 201 stops working. At this time, if the user issues a release instruction through the touch screen, the controller 101 controls the air release part 204, and the huge pressure will break the blockage.

[0023] Example 2, reference Figures 1-2 , which is the second embodiment of the present invention. Different from the previous embodiment, the air compression unit 201 includes a compression cylinder 201a, a piston plate 201d is arranged inside the compression cylinder 201a, a connecting rod 201c is arranged at the bottom of the piston plate 201d, a rocker arm 201b is arranged on the top of the connecting rod 201c, the cross-section of the piston plate 201d is the same as the inner wall shape of the compression cylinder 201a, a motor 202 is arranged at the bottom of the compression cylinder 201a, the output end of the motor 202 is fixedly connected to the rocker arm 201b, the rotation of the motor 202 will drive the rocker arm 201b to rotate, the rotation of the rocker arm 201b drives the connecting rod 201c to rotate, the connecting rod 201c will drive the piston plate 201d to slide inside the compression cylinder 201a, the piston plate 201d slides up and down to compress the air, the motor 202 is electrically connected to the controller 101, and a power supply 203 is arranged on the side of the motor 202.

[0024] Furthermore, a one-way air intake valve 201e is provided at the top of the compression cylinder 201a, and the one-way air intake valve 201e is electrically connected to the controller 101. When the piston plate 201d slides downward, the one-way air intake valve 201e opens, and external air enters the compression cylinder 201a. The one-way air intake valve 201e is connected to the compression cylinder 201a, and an air intake filter 201f is provided at one end of the one-way air intake valve 201e away from the compression cylinder 201a. The air intake filter 201f is connected to the one-way air intake valve 201d. 01e is connected. When external air enters the compression cylinder 201a, the air intake filter 201f will filter the air to remove most of the impurities and moisture in the air. A one-way exhaust valve 201g is provided at the end of the top of the compression cylinder 201a away from the one-way intake valve 201e. The one-way exhaust valve 201g is connected to the compression cylinder 201a. When the piston plate 201d slides upward, the one-way exhaust valve 201g opens to discharge the filtered air in the compression cylinder 201a.

[0025] Furthermore, the air release part 204 includes a compressed air tank 204a arranged on the side of the compressed air cylinder 201a, and the compressed air tank 204a is connected to the one-way exhaust valve 201g. The filtered air in the compressed air cylinder 201a will be discharged into the compressed air tank 204a to prepare for the subsequent cleaning of the blockage of the sampling tube.

[0026] Furthermore, a pressure sensor 204b is provided on the top of the compressed air tank 204a, and the pressure sensor 204b is electrically connected to the controller 101. The pressure sensor 204b monitors the air pressure value in the compressed air tank 204a in real time, and feeds it back to the processor, which is displayed on the touch screen 102. A release solenoid valve 204d is provided at one end of the compressed air tank 204a away from the compressed cylinder 201a, and the release solenoid valve 204d is electrically connected to the controller 101. A sampling tube connector 204c is provided at one end of the release solenoid valve 204d away from the compressed air tank 204a. The sampling tube connector 204c is adapted to be connected to the sampling tube. For different sampling tubes, sampling tube connectors 204c of different sizes can be adapted. When the air pressure value in the compressed air tank 204a reaches the set value, the touch screen can be operated to issue a release command, and the compressed air in the compressed air tank 204a is released into the sampling tube through the sampling tube adapter to blow out foreign matter in the sampling tube.

[0027] Specifically, when the user sets the target compressed air pressure through the touch screen and starts compression, the data is transmitted to the controller 101, and the control sends a start command to the driving DC motor 202. The power supply 203 supplies power to the motor 202, and the motor 202 drives the control piston to compress the air after being filtered by the filter (filtering impurities, moisture, etc.), and continuously discharges the compressed air to the compressed air tank 204a. When the detected pressure reaches the set target compressed air pressure value, the motor 202 stops working. At this time, if the user issues a release command through the touch screen, the controller 101 controls the release solenoid valve 204d to open, and the compressed air is instantly released into the blocked sampling tube after passing through the sampling tube connector 204c, and the huge pressure will break the blockage.

[0028] When the motor 202 drives the rocker arm 201b to rotate, the rocker arm 201b drives the piston plate 201d to move up and down through the connecting rod 201c. When the piston moves downward, the air passes through the air intake filter 201f and enters the compressed air cylinder 201a via the one-way air intake valve 201e. When the piston moves upward, the air in the compressed air cylinder 201a is discharged into the compressed air tank 204a via the one-way exhaust valve 201g. In this way, an air compression process is completed. By repeating this process, the air is continuously compressed into the compressed air tank 204a until the set pressure value is reached.

[0029] Example 3, reference Figures 1-2 , which is the third embodiment of the present invention. Different from the previous embodiment, when cleaning the blockage in the sampling tube, the air pressure in the compressed air tank 204a should be set in advance according to the different sampling tube diameters and the type of medium blocking the sampling tube to achieve the best cleaning effect.

[0030] Due to the diverse working environments in the sampling tube, different cleaning pressures are required for different blocking media, including: air-powder mixed media (without water vapor), air-powder mixed media (with water vapor), muddy media, and easily crystallized media.

[0031] When cleaning the above blocked media, the air pressure in the compressed air tank 204a is set as follows:
