Embodiment
Describe the utility model in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the feature in embodiment and embodiment in the utility model can be mutually combined.For sake of convenience, hereinafter such as
There are " on ", " under ", "left", "right" printed words, only represent that the upper and lower, left and right direction with accompanying drawing in itself is consistent, not to structure
Play restriction effect.
A kind of device for recovering powder, as shown in figs. 1 and 3, including sandblasting sealing chamber 10, the sandblasting sealing chamber 10 have direction
Treat sandblasting object（Steel plate）22 the first side and the second side of the shower nozzle for installing sand-blasting gun 14, first side and the second side phase
To setting, and the first side opening of the sandblasting sealing chamber 10；In other words, generally one one side of sandblasting sealing chamber 10 is open
Box, opening surface end is equipped with industrial bar brush, and bar brush causes sandblasting sealing chamber 10 to turn into one after being contacted with welding steel 22
Relative confined space.Industrial bar brush is four square frames that the industrial bar brush of a use makes, and its main function is sealing, is prevented
More dust leakages.The sandblasting sealing chamber 10 is provided with device for recovering powder, preferably Wen's dust arrester.
As shown in Figures 4 and 5, the device for recovering powder includes trunnion 105 and siphon pipe 104；One end of the trunnion 105
For compressed air inlet, the other end is dust outlet；The trunnion 105 is connected by siphon pipe 104 and the sandblasting sealing chamber 10
It is logical, rubber ring 103 is provided between siphon pipe 104 and sandblasting sealing chamber 10.As shown in figure 3, the dust outlet of the trunnion 105 leads to
Piping 15 connects with dust settling pocket 16.As shown in figure 4, the trunnion 105 is arranged on sandblasting sealing chamber 10 by support plate 102
On, rubber ring 103 is provided between pipeline and support plate 102.
As shown in figure 3, the siphon pipe 104 is arranged on the side wall of sandblasting sealing chamber 10 with one end that sandblasting sealing chamber 10 connects
Bottom.
As shown in figure 1, remaining sand reclaims for convenience, the lower end of the sandblasting sealing chamber 10 is equipped with remaining sand retracting device, institute
State the remaining sand recovery port 11 that remaining sand retracting device includes being opened on the lower end of sandblasting sealing chamber 10, the remaining sand recovery port 11 with it is remaining
Sand collection box connects.
The circumference of first side of the sandblasting sealing chamber 10 is equipped with sand block structure, and the sand block structure is used to be arranged on sandblasting envelope
Closed chamber 10 and treat between sandblasting object.As shown in Fig. 2 the sand block structure is to be distributed on the first side opening of sandblasting sealing chamber 10
Industrial bar brush 25 in surrounding.
During sandblasting, the front and back position that fixed handle adjusts sand-blasting gun can be adjusted by sand-blasting gun, to obtain different sprays
Sand width and sandblasting dynamics, to carry out derusting by sandblasting to weld seam 100.By adjusting the front and back position of sand-blasting gun, malleation sand flow
The speed of travel of operating pressure, sand speed and walking dolly, makes sandblasting effect reach optimal, while makes sand using amount minimum, work effect
Rate highest.
In order to adjust the shower nozzle eject position of sand-blasting gun 14, sand-blasting gun adjustment handle is housed on the sandblasting sealing chamber 10,
The rotation of sand-blasting gun adjustment handle can drive the shower nozzle of the sand-blasting gun 14 to be moved along shower nozzle axis direction.
Because the plane of welding steel is not very smooth, while dolly is constantly being walked, and hairbrush has friction with steel plate, has
Abrasion.In order to solve this problem, the present embodiment pushes away forward industrial bar brush frame by thrust caused by four expansion links, makes hair
Brush is adjacent to and on welding steel, makes it to prevent the dust in sandblasting sealing chamber 10 from spilling, can allow outside fresh sky again
Gas enters（Under Wen's dedusting, negative pressure will be produced in sandblasting sealing chamber 10）.
Thus, in sandblasting procedures, industrial hairbrush front end will produce friction with welding steel, and hairbrush constantly will be worn change
Short, these abrasions shorten is compensated the thrust caused by four expansion links automatically, to ensure hairbrush front end with having welded
Steel plate remains suitable pressure.
The expansion link of buffering has four, and its range is 30mm, working thrust（Constant pressure）For 5-10N.
The content that above-described embodiment illustrates should be understood to that these embodiments are only used for being illustrated more clearly that the utility model,
Rather than limitation the scope of the utility model, after the utility model has been read, those skilled in the art are new to this practicality
The modification of the various equivalent form of values of type each falls within the application appended claims limited range.
