Description

Technical Field

[0001] The utility model belongs to the technical field related to dust removal, in particular to a down-feed and up-return dust removal system for a welding workshop. Background Art

[0002] In a large welding workshop, especially when welding large structures, smoke and dust often float at a height of 6-8 meters due to the large number of scattered welding stations, making it difficult to effectively discharge. In this environment, smoke often lingers inside the workshop, affecting the cleanliness of the working environment and the health of the workers. In addition, due to the large size of the workpiece, the height of the crane is about 10 meters, and the frequent hoisting operations make it difficult to implement traditional point-to-point or local centralized management methods, making it difficult to capture smoke and dust, and the effect is limited.

[0003] Traditional point-to-point or local centralized management is difficult to capture, and the workstation range is large, so it cannot achieve good results. The ventilation and dust removal management of the entire welding workshop requires large investment and high operating costs, and the collection effect on the welding of tall workshops is not good. Therefore, a down-feed and up-feed dust removal system is urgently needed in the welding workshop to solve the above technical problems. Utility Model Content

After treatment, there is no obvious accumulation and suspension of welding smoke in the workshop; the addition of the cleaning component ensures the cleanliness of the return air port filter, ensuring the long-term stable operation of the system.

[0008] As a further improvement of the above scheme, the cleaning assembly includes a brush body arranged on a mounting block, the mounting block is movably arranged on the inner side of a supporting block, the supporting block is arranged on a sliding block, a through slot is arranged on the sliding block, and the through slot is movably arranged on a guide rod.

[0009] The technical effect of the above improvement is: simplifying the cleaning process of the filter and improving maintenance efficiency.

[0010] As a further improvement of the above solution, the mounting block is connected to the supporting block by bolts; the supporting block is arranged in the groove of the sliding block, and the two are interference fit.

[0011] The technical effect of the above improvements is: providing a more solid structural connection, ensuring the reliability and safety of the cleaning component during operation.

[0012] As a further improvement of the above solution, fixed sleeves are arranged side by side on the return air duct, both ends of the fixed sleeves are arranged in the guide rods, and the guide rods are arranged at the side ends of the return air duct.

[0013] The technical effect of the above improvement is: ensuring the smooth movement of the cleaning component along the return air duct, improving the cleaning efficiency and the convenience of operation.

[0014] As a further improvement of the above solution, the guide rod and the sliding block are transitionally matched.

[0015] The technical effect of the above improvement is that the sliding block slides flexibly on the guide rod, thereby improving the cleaning efficiency and the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical solution, the utility model is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0021] like Figure 1-3As shown, the specific scheme of this embodiment is: a downward-delivered and upward-returned dust removal system in a welding workshop, comprising a dust removal main unit 1, air inlet ducts 2 are arranged on both sides of the dust removal main unit 1, an air inlet cylinder 3 is arranged at the lower end of the air inlet duct 2, and the air inlet cylinder 3 is arranged to be adjustable, and the air inlet cylinder 3 is adjusted by a knob-type structure; a return air duct 4 is arranged at the upper end of the dust removal main unit 1, and a return air port 5 is arranged on the return air duct 4; a cleaning component for cleaning the filter on the return air port 5 is movably arranged on the return air duct 4.

[0022] Specifically, the system starts to run, the dust removal host 1 is started, and it is ready to purify the smoke. The adjustable large-volume diffused air inlet 3 supplies air, giving the smoke generated by welding an upward thrust, pushing the originally 6-8m suspended smoke upward, and is captured by the return air port 5 set on the grille return air duct 4 on the top of the traveling crane, and enters the dust removal host 1 for purification. The cleaning component can be used to clean the filter on the return air port 5.

[0023] The dust removal host 1 equipment is arranged between two pillars in the workshop, occupying a small area; it does not interfere with the on-site production process and does not affect the crane hoisting. Multiple systems are arranged in the workshop and opened and closed according to actual usage;
