Multi-station top-suction type exhaust and dust processing device with function of automatic station conversion

Abstract

The invention discloses a multi-station top-suction type exhaust and dust processing device with a function of automatic station conversion, which comprises a rail arranged on a support of a workshop, and a traveling crane driven by a power mechanism to travel on the rail. A plurality of top-suction type dust hoods corresponding to pollution sources are arranged on the traveling crane, the upper end of each dust hood is communicated with a venting pipe and a controlling valve, the lower end of each dust hood is provided with an exhaust inlet hole, the venting pipe of each dust hood is parallelly connected onto a main air pipe, the main air pipe is communicated with a bag filter system arranged outside the workshop, a photoelectric switch is arranged on the edge of an opening at the lower end of each dust hood, a limit switch which determines the stopping position of the traveling crane is arranged on the rail, and the limit switch, the photoelectric switches, a power mechanism, the controlling valve and a bag filter are all connected with a PLC (programmable logic controller) via cables. The multi-station top-suction type exhaust and dust processing device with the function of automatic station conversion solves the problem that amorphous dust in the workshop with serious dust pollution is difficult to gather and the like, is capable of running stably over a long period of time with enhanced processing effect.

Description

Technical field: [0001] The invention relates to a waste gas dust collection device, in particular to a multi-station top suction type automatic transposition waste gas dust collection device. Background technique: [0002] Large-scale and heavy-duty processing industries such as steel pipe welding, casting, mechanical coating, and metallurgy, due to the dense arrangement of equipment and workstations on the assembly line that work intermittently or continuously, and the narrow operating space, the collection of waste generated by welding, pouring, spraying, and smelting processes The dust collection hood of unorganized dust is difficult to arrange and fix on the ground, and the difficulty of collecting it has become a recognized problem. Invention content: [0003] In order to overcome the defects of the prior art, the object of the present invention is to provide a multi-station top-suction type automatic transposition exhaust gas dust collection device, which effectivel...

Problems solved by technology

[0003] In order to overcome the defects of the prior art, the object of the present invention is to provide a multi-station top-suction type automatic transposition exhaust gas dust collection device, which effectively utilizes the space for layout and solves the problem of equipment and stations on the assembly line that work intermittently or continuously. The arrangement of appliances is dense, the operating space is narrow, and the environmental dust pollution is serious. The unorganized dust in the production workshop is difficult to collect on the ground, so as to ensure the collection of unorganized waste gas. The device can run stably for a long time, improve the treatment effect, solve environmental pollution, and purify production. workshop air
