In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0027] Example 1

[0028] In order to smoothly introduce the dust and smoke collected in the dust collecting device on the plasma cutting machine into the dust collector, specifically, to introduce the dust-containing smoke captured by the mobile dust collecting device into the fixed dust collector air duct; this embodiment provides a new water-sealed sliding duct air induction device, see Figure 1 、 Figure 2 , including a dust collecting part 1 for collecting dust-containing flue gas from a dust suction port; a connecting part 2 for receiving the dust-containing flue gas from the dust collecting part 1, so that the received dust-containing flue gas is sent to the dust collector through a fixed dust sending part 3 under the soft sealing mode of the connecting part 2.

[0029] For example, the dust collecting member 1 is used to absorb dust-containing fumes generated by the workpiece being cut on the water bed 6 during operation of the plasma cutting machine, thereby reducing the impact on the working environment, purifying the working environment of the staff, and effectively protecting the health of the staff.

[0030] The connecting member 2 is an intermediate medium connecting the dust collecting member 1 and the dust collector, so as to smoothly and leak-free transport the dust-laden flue gas to the dust collector for purification. The dust conveying member 3 is a fixed dust conveying pipe, and the outlet of the dust conveying pipe is connected to the dust collector.

[0031] In the specific implementation process, see Figure 2 The connecting piece 2 is a trough structure with an upper opening 21. The lower part of the trough structure is sealed by liquid 4, and the upper part forms a sealed cavity pipe 22 under the action of the liquid 4. The dust outlet end of the dust collecting piece 1 enters the connecting piece 2 from the opening 21 and is located in the sealed cavity pipe 22, so that the dust-laden flue gas from the dust collecting piece 1 is soft-sealed in the connecting piece 2 through the liquid 4. On the one hand, the dust-laden flue gas can be smoothly transferred from the dust collecting piece 1 to the dust sending piece 3. On the other hand, during the transfer process, since it is a sealed environment, leakage can be avoided.

[0032] More specifically, a through hole is provided on the upper portion of one side of the connecting member 2 to communicate with the inlet of the dust conveying member 3 so as to transfer the dust-laden flue gas in the sealed cavity pipe 22 on the upper portion of the connecting member 2 to the fixed dust conveying member 3 .

[0033] In the specific implementation process, see Figure 2 The dust outlet end of the dust collecting member 1 is opposite to the bottom end surface gap of the top plate 23 of the connecting member 2, and slides along the length direction of the opening 21 under the drive of the trolley 5 of the plasma cutting machine. That is, the dust collecting member 1 absorbs the dust-containing flue gas generated during the operation of the plasma cutting machine in real time during the sliding process, and transports it to the dust collector through the connecting member 2 in real time. It has a simple structure, convenient operation, smooth transportation without leakage, and good dust collection effect.

[0034] The dust collection member 1 is a movable dust collection pipe, and at least two dust collection branches 11 are provided on the side of the dust collection pipe away from the connecting member 2. For example, one dust collection branch pipe 11 is used to collect the dust-containing fume generated by the lower part of the cutting piece, and the dust collection branch pipe 11 can move synchronously along the trolley 5 of the plasma cutting machine, and the other dust collection branch pipe 11 is used to collect the dust-containing fume generated by the upper part of the cutting piece, and both dust collection branch pipes 11 can move synchronously with the trolley 5 of the plasma cutting machine.

[0035] More specifically, see Figure 2The longitudinal cross-section of the connecting member 2 is L-shaped, and a baffle 24 is provided on the upper part along its length direction. The top end of the baffle 24 is vertically connected to the top plate 23, and the bottom end is opposite to the bottom plate 25 of the connecting member 2, so that the dust outlet end of the dust collecting member 1 enters the inner cavity of the connecting member 2 through the opening 21 and then passes through the bottom end of the baffle 24 to be opposite to the gap of the top plate 23 of the connecting member 2, and the bottom end surface of the baffle 24 is below the liquid level, that is, the dust outlet end of the dust collecting member 1 is above the liquid level and accommodated in the sealed cavity pipe 22 to prevent dust-laden flue gas from leaking.

[0036] Further, see Figure 2 The longitudinal cross-section of the dust collecting member 1 located in the pipe section inside the connecting member 2 is U-shaped, and the end face where one vertical side of the U is located is opposite to the gap between the top surface of the connecting member 2 and is located above the liquid level. The end face where the other vertical side of the U is located is used to collect dust-containing flue gas generated during the cutting process of the plasma cutting machine; the bottom end face of the baffle 24 is accommodated in the opening of the U, so that the dust outlet of the dust collecting member 1 is located in the sealed cavity pipe 22.

[0037] In this embodiment, the devices are made of thin steel plates and are light in weight. They can float on the trolley travel mechanism of the plasma cutting machine. Due to their small size and light weight, the loads they bear when the trolley is traveling are relatively small, and they do not affect the accuracy of the trolley's movement and cutting.

[0038] Furthermore, the utility model uses a water-sealed method, so that dust-laden smoke will not diffuse out from the water-sealed liquid surface of the water tank. The sealing tightness is good and the sealing performance is reliable. In addition, the water-sealed method is a soft seal method, which will not cause wear to the moving dust collecting parts and connecting parts. Therefore, there is no need for frequent maintenance and replacement of parts, the operating cost is low, the service life is long, and the structure is simple and practical, which is easy to inspect and maintain.

[0039] It should be noted that, in the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0040] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0041] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
