Description

Technical Field

[0001] The utility model relates to the technical field of welding construction, in particular to a multi-directional telescopic welding smoke collector. Background Art

[0002] During the welding process, welding smoke (welding smoke for short) will be generated and spread everywhere. The main harmful substances in welding smoke are Fe 2 O 3 、SiO 2 , MnO, HF, etc., among which Fe 2 O 3 , generally accounting for 35.56% of the total smoke, followed by SiO 2 The content of nitrate is 10% to 20%, and that of MnO is 5% to 20%. The main components of toxic and harmful gases in welding smoke are CO, CO 2 , O 3 、NO X , CH 4 Among them, CO accounts for the largest proportion.

[0003] In some welding construction sites, in order to improve the efficiency of construction, multiple welding points are set up and construction is carried out simultaneously, resulting in a large amount of toxic and harmful substances entering the surrounding gas environment in a short period of time, causing pollution and damage to the environment and physical harm to the construction workers. Some technologies use exhaust fans to extract the generated welding smoke to limit its dispersion into the air, and set the exhaust fans next to the welding position. One exhaust fan is required for each welding point; such a solution has poor suction efficiency and is relatively cumbersome to set up, making it difficult to meet the needs of simultaneous construction at multiple points.

[0004] It can be seen that there is still room for improvement in the current welding smoke control process, and adjustments and optimizations should be made to improve the efficiency of welding smoke control and the convenience of welding smoke treatment. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes a multi-directional retractable welding smoke collector. By setting up the collector at the construction site, the welding smoke at each point can be collected, and the suction points can be flexibly set to meet the needs of multi-point construction. It can also improve the suction effect, prevent the welding smoke from drifting into the atmosphere, and reduce the harm caused by the welding smoke to the environment and human body.

[0006] In order to achieve the above-mentioned purpose, the welding smoke collector disclosed in the utility model can adopt the following technical solutions:

[0007] A multi-directional retractable welding smoke collector comprises a main pipeline for forming negative pressure and bending and extending laterally, a plurality of main adsorption pipelines are arranged on the main pipeline, the main adsorption pipelines extend downward and are controllably retractable; a plurality of secondary pipelines are also connected to the main pipeline, the secondary pipelines bend and extend laterally, and a plurality of secondary adsorption pipelines are arranged on the secondary pipelines, the secondary adsorption pipelines extend downward and are controllably retractable; the front end of the main pipeline is connected to a negative pressure main machine for sucking the main pipeline and forming negative pressure, and the air outlet end of the negative pressure main machine is connected to a purifier for purifying welding smoke.

[0008] The welding smoke collector disclosed above uses the main pipe as the main channel for adsorption, and the main adsorption pipe adsorbs and collects the welding smoke in the area where the main pipe passes; at the same time, a number of secondary pipes are arranged to increase the coverage area, and the secondary adsorption pipes simultaneously enhance the adsorption of welding smoke. Since the main adsorption pipe and the secondary adsorption pipe are both retractable and adjustable, and the extension direction of the main pipe and the secondary pipe can also be adjusted, it can effectively adsorb and purify the welding smoke in the centralized welding processing site.

[0009] Furthermore, the composition structure of the main pipeline can be constructed in various forms, which are not limited to a single one. Here, an optimization is made and one feasible option is proposed: the main pipeline includes a plurality of telescopic main air ducts and a plurality of main pipe joints, and the main pipe joints include a main adsorption interface connected to the main adsorption pipeline, at least two main air duct interfaces for connecting the telescopic main air duct, and at least one secondary air duct interface for connecting the secondary pipeline. When such a solution is adopted, the main pipe joint serves as a connection node between the telescopic main air duct, the main adsorption pipeline and the secondary pipeline.

[0010] Furthermore, the fixing method of the main pipeline is not limited to a single method. Here, an optimization is made and one of the feasible options is proposed: the main pipeline is fixed with the help of a hoisting structure, and the hoisting structure includes a horizontally extending cable, on which a plurality of pulleys are arranged, and the pulleys are connected to the main pipeline joint and drive the main pipeline joint to move. When such a scheme is adopted, the cable is connected and fixed by two columns and tightened as support. The pulley can move along the cable and drive the main pipeline joint to move, thereby driving the main pipeline to extend.

[0011] Furthermore, the connection method between the pulley and the main pipe joint is not limited to a single one, and an optimization is made here and a feasible option is proposed: the pulley is connected to the main pipe joint through a lifting cable. When such a solution is adopted, the lifting cable can adjust the height of the main pipe joint.

[0012] Furthermore, in the present invention, the structure of the main adsorption pipeline is constructed in various forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the main adsorption pipeline includes a lifting adsorption main pipe, the upper end of the lifting adsorption main pipe is connected to the main adsorption interface, and the lower end is provided with a main control head, which is controlled to open and close by a main air inlet valve. When such a solution is adopted, the lifting adsorption main pipe can adopt an elastic telescopic pipe, and air can be inlet when the main control head at the lower end is opened, and air can be stopped when the main control head is closed.

[0013] Furthermore, the air intake is controlled, and an optimization is made here and one of the feasible options is proposed: the main air duct interface and the secondary air duct interface of the main pipe joint are both provided with a main air valve for controlling the on-off. When such a solution is adopted, the main air valve can control the on-off of the main pipe and the secondary pipe, thereby controlling the welding smoke adsorption area in the construction area.

[0014] Furthermore, in the present invention, the secondary pipeline can be constructed in a variety of forms, which are not limited to a single form. Here, an optimization is made and one feasible option is proposed: the secondary pipeline includes a plurality of telescopic secondary air pipes and a plurality of secondary pipe joints, and the secondary pipe joints include a secondary adsorption interface for connecting the secondary adsorption pipeline, and two secondary air pipe interfaces for connecting the telescopic secondary air pipe. When such a solution is adopted, the length of the secondary air pipe can be set as needed through multiple connections.

[0015] Furthermore, in the present invention, the secondary pipe joint can be arranged in a variety of ways, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the secondary pipe joint is connected with a support frame, and a fixing structure is arranged on the support frame to fix the secondary pipe joint. When such a solution is adopted, a walking structure is arranged under the support frame to facilitate the movement of the secondary pipe joint to reasonably arrange the adsorption area.

[0016] Furthermore, the secondary adsorption pipeline can be constructed into a variety of feasible solutions, which are not limited to the only one. Here, we optimize and propose one of the feasible options: the secondary adsorption pipeline includes a lifting adsorption secondary pipe extending downward, the upper end of the lifting adsorption secondary pipe is connected to the secondary adsorption interface, and the lower end is provided with a secondary control head, which is controlled by the secondary air inlet valve. When such a solution is adopted, the secondary control head serves as a node of the lifting adsorption secondary pipe and the telescopic secondary air pipe, so that it is easy to control the arrangement of the extended adsorption area in the construction area.

[0017] Furthermore, the utility model optimizes the structure of the secondary pipe joint, and here proposes one feasible option: a secondary air valve is provided at the secondary air pipe interface of the secondary pipe joint. When such a solution is adopted, the secondary air valve is used to control the opening and closing of part of the extended adsorption area.
