The internal diameter of the suction hose 3 is smaller than the diameter of the spherical element 20. Optionally, the suction device 1 may include, but is not limited to, a Roots blower and an industrial vacuum cleaner.

The directional switching mechanism 4 includes a first housing 401, a directional switching assembly, and a first drive mechanism 402. The first housing 401 is provided with a first discharge port 407, a first hose inlet 408, and a first hose outlet 409. Here, the first hose inlet 408 is for the suction hose 3 to enter, and the first hose outlet 409 is for connecting to the inspection connection port 23 of the equipment 19 to be inspected. The directional assembly is disposed within the first housing 401 and is switchable between a first position and a second position; in other words, the directional assembly is movable within the first housing 401. It is set up as follows. The directional assembly is provided with a connecting passage, and when the directional assembly is in the first position, the connecting passage of the directional assembly communicates with the first hose inlet 408 and the first hose outlet 409; When the directional assembly is in the second position, the connecting passage of the directional assembly communicates the first hose inlet 408 and the first outlet 407. A first drive mechanism 402 is connected to the directional assembly for driving the directional assembly into motion.

In order to prevent repair personnel from being exposed to excessive radiation due to the spherical elements 20, shields are usually installed at equipment and pipe segments where clogging failures may occur, and upstream of the shields, the spherical elements 20 are installed. It is necessary to install a connecting pipe that avoids direct exposure and facilitates clearing of blockages. The connecting pipe has various forms, such as a pipe communication device for a high temperature gas furnace disclosed in Chinese Patent Application Publication No. 111677966, or the first three-way joint 21 shown in FIG. The inspection connection port 23 is connected to a pipe communication device or a first three-way joint 21 . If unclogging is required, the inspection connection 23 can be opened and the first hose outlet 409 can be connected to the inspection connection 23, and when the inspection is completed, the first hose outlet 409 can be removed from the inspection connection 23. , the inspection connection 23 can be closed again.

The hose feeding mechanism 5 is provided at the first hose inlet 408 and includes a main driving wheel 501, a driven wheel 502, and a second driving mechanism 503. The main driving wheel 501 and the driven wheel 502 are both rotatably provided, and have a gap between them through which the suction hose 3 passes. The second drive mechanism 503 is connected to the main driving wheel 501 in order to drive and rotate the main driving wheel 501.

In the high temperature gas furnace suction device according to the embodiment of the present invention, during use, the inspection connection port 23 of the equipment 19 to be inspected is opened, and the first hose outlet 409 of the direction switching mechanism 4 is connected to the inspection connection port 23. do. The first drive mechanism 402 drives the directional assembly to move to the first position, such that the connecting passage of the directional assembly communicates with the first hose inlet 408 and the first hose outlet 409. do. The second drive mechanism 503 of the hose feed mechanism 5 drives the main driving wheel 501 to rotate, and the suction hose 3 between the main driving wheel 501 and the driven wheel 502 is rotated in turn under the driving action of the main driving wheel 501. The equipment 19 to be inspected is entered via the first hose inlet 408, the connection channel, the first hose outlet 409 and the inspection connection 23.

Due to the suction action of the suction device 1, a suction airflow is generated in the suction hose 3, and the dust and debris in the equipment 19 to be inspected whose particle size is smaller than the inner diameter of the suction hose 3 flows along the suction hose 3, and the final This completes the removal of dust and debris from the clogged part of the equipment 19 to be inspected.

Spherical elements 20 in the equipment 19 to be inspected or large debris whose diameter is larger than the inner diameter of the suction hose 3 are attracted to the mouth of the suction hose 3. The second drive mechanism 503 of the hose feed mechanism 5 drives the main drive wheel 501 in reverse, and under the drive of the main drive wheel 501, the suction hose 3 is moved between the spherical element 20 and the large size adsorbed at the pipe opening. Together with the debris, the equipment 19 to be inspected, the inspection connection port 23, the first hose outlet 409, the connection passage, and the first hose inlet 408 are exited, and after exiting upstream of the first hose inlet 408, the The second drive mechanism 503 stops rotation. The first drive mechanism 402 drives the directional assembly to move to the second position, and the connecting passage of the directional assembly communicates the first hose inlet 408 and the first outlet 407. The suction device 1 stops suction, the suction force of the suction hose 3 on the spherical element 20 or large debris is lost, and the spherical element 20 or large debris falls from the pipe opening of the suction hose 3 and enters the first hose inlet 408. , enters the first outlet 407 via the connecting passage, thereby completing the unblocking of the spherical element 20 and large debris at the blockage location of the equipment 19 to be inspected. If there are a large number of clogged spherical elements 20 or large pieces of debris, the equipment 19 to be inspected can be unclogged several times by suction using the suction hose 3. When the clogging is completed, the first hose outlet 409 is removed from the inspection connection port 23, and the inspection connection port 23 is further closed.

Since it is necessary to send the suction hose 3 into the equipment 19 to be inspected using the hose feed mechanism 5 and to extract the suction hose 3 from the equipment 19 to be inspected, so that the main drive wheel 501 can drive the suction hose 3, It is necessary to make the gap between the main driving wheel 501 and the driven wheel 502 smaller than the diameter of the suction hose 3, so that the cross-sectional area between the main driving wheel 501 and the driven wheel 502 of the suction hose 3 is smaller than the area. When the spherical elements 20 or large debris are moved into the suction hose 3 and discharged, the spherical elements 20 or large debris tend to become clogged between the main driving wheel 501 and the driven wheel 502. The suction hose 3 adsorbs the spherical element 20 and large debris, and the direction switching assembly guides the spherical element 20 and large debris to the first discharge port 407 and discharges the spherical element 20, thereby preventing the spherical element 20 from becoming stuck between the main driving wheel 501 and the driven wheel 502. Problems causing failure of the suction device of the high temperature gas furnace can be avoided.

There is no need to dismantle or remove the line, reducing the number of installation and removal steps, which makes the operation of the unclog operation more convenient and requires less on-site operation time for the repairer. This can effectively reduce the on-site work time of repair personnel and avoid excessive radiation exposure to repair personnel.
