Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1:

the utility model provides a vehicle welding workshop dust removal ventilation system, as shown in figure 1, including dust cage 1, flue 3, sack cleaner 4, chimney 6 and control box 7, dust cage 1 is fixed directly over the welding station, the axis of dust cage 1 is arranged along vertical direction, dust cage 1 is formed by the stainless steel skin welding, dust cage 1's appearance is the round platform form, sack cleaner 4 passes through mounting bracket 41 and installs subaerially outside the welding workshop, mounting bracket 41 is the stainless steel frame, flue 3 is with the upper end of dust cage 1 and sack cleaner 4's entrance connection, sack cleaner 4's exit end passes through axial fan 5 and is connected with chimney 6, chimney 6 is fixed subaerially outside the welding workshop. The flue 3 in this embodiment is a stainless steel corrugated pipe.

In this embodiment, the number of the bag-type dust collectors 4 is set to 3 and the bag-type dust collectors are connected in series, and the dust removal effect can be optimized by setting 3 bag-type dust collectors 4.

In the present embodiment, the number of dust collection covers 1 is set to be plural as required and connected in parallel with each other.

In order to optimize the dust removal effect, an automatic valve 2 is arranged at one end of the dust collection cover 1 connected with the flue 3, and the automatic valve 2 is an automatic flap valve; still including fixing control box 7 on the welding shop wall in this embodiment, 7 internally mounted of control box have the controller, and inside automatically-controlled valve switch and the axial fan switch of being provided with of control box, automatically-controlled valve switch and axial fan switch are respectively through controller and automatically-controlled

valve

2 and 5 electric connection of axial fan.

The specific implementation process is as follows: when the welding workshop starts working, the axial flow fan switch is pressed down, the axial flow fan 5 starts to draw air, all flues 3 start to draw air at the moment, when parts need to be welded, welding materials are conveyed to a welding workbench below the adjacent dust hood 1, the automatic valve switch corresponding to the dust hood 1 is opened, the automatic valve 2 is opened at the moment, and welding smoke and dust below the dust hood 1 can be sucked and removed by the dust hood 1. Welding smoke and dust generated in the welding process enter the bag-type dust collector 4 through the flue 3 to be uniformly subjected to dust removal treatment, and clean air is discharged from the chimney 6; after the welding work is finished, the automatic valve switch is closed, the automatic valve 2 is closed at the moment, the corresponding dust hood 1 stops working, and meanwhile, the effect of preventing smoke dust from flowing back can be achieved. By analogy, one or more dust collection hoods 1 are selected to work simultaneously according to actual requirements, and different dust collection hoods 1 can be used by multiple persons during simultaneous welding without mutual interference, so that the welding dust removal work is facilitated.

Example 2:

example 2 differs from example 1 in that: as shown in fig. 2, a smoke sensor 11 is mounted on the lower end of the dust collection cover 1, and the smoke sensor 11 is electrically connected to the automatic valve 2 through a controller. The lower end of the dust collection cover 1 is also provided with a temperature sensor 12, and the temperature sensor 12 is electrically connected with the automatic valve 2 through a controller. An electromagnet 13 is fixed at the lower end of the dust collection cover 1, the electromagnet 13 is electrically connected with a temperature sensor 12 and a smoke sensor 11 through a controller respectively, when the smoke sensor 11 detects smoke or the temperature sensor 12 detects that the temperature is more than 40 ℃, the smoke sensor 11 or the temperature sensor 12 controls the automatic valve 2 to be opened through the controller, meanwhile, the electromagnet 13 is electrified, and the electromagnet 13 can absorb welding slag splashed in the welding process; after the welding finishes, when smoke transducer 11 no longer detects smog or temperature sensor 12 detects the temperature and is below 25 ℃, smoke transducer 11 or temperature sensor 12 pass through controller control automatic valve 2 and close, and electro-magnet 13 cuts off the power supply simultaneously, and the welding slag that is adsorbed by electro-magnet 13 drops subaerial automatically, makes things convenient for the concentrated clearance of welding slag.

As shown in fig. 2, the present embodiment further includes a condenser 8, a gas outlet end of the bag-type dust collector 4 is connected to a medium layer of the condenser 8, and an outlet end of the medium layer is connected to the chimney 6; the entrance point of the condensate layer of condenser 8 is connected with cooling tower 9 through pipeline, water pump 91, and water pump 91 is connected with the bottom of cooling tower 9, and the water of the exit end of the condensate layer of condenser 8 directly drains to cooling tower 9 top.
