[0075]overall structure

[0076] Figure 1 to Figure 3 The reference numeral 1 in is the sandblasting chamber of the present invention. Such as figure 1 and figure 2 As shown, although its overall shape is not particularly limited, this working room 1 is manufactured so that a worker M can enter and work with a workpiece W, and the working room 1 is equipped with side walls 11 to 14, a top plate 15, and a bottom plate 16. The surrounded substantially box-shaped main unit 10; the dust collecting unit 20 which ventilates the main unit 10 during the blasting process; and the ventilation unit 30 which ventilates the main unit 10 during painting.

[0077] main unit

[0078] The above-mentioned main unit 10 constituting the working chamber 1 of the present invention is a box-shaped chamber made of, for example, metal and formed by two pairs of opposite side walls ( 11 and 12 and 13 and 14 ), a top plate 15 and a bottom plate 16 . This main unit 10 is formed with a work space 1...

[0131] Another embodiment construction (second specific example) of working chamber 1 of the present invention will refer to Figures 5 to 7 to describe.

[0132] Figures 5 to 7 The working chamber 1 of this particular example shown in is provided with a collection unit 40 constructed from a collection duct 41 , a cyclone 42 and an exhaust duct 43 . The Studio 1 with the above reference Figures 1 to 4 The working chamber 1 of the first embodiment described above is different in that a second opening / closing member 44 and a third opening / closing member 45 are provided in the ventilation duct 10b. Other constructions and references Figures 1 to 4 The working chambers 1 of the first specific example described are the same, and therefore, description of common parts will be omitted.

[0133] The cyclone 42 constituting the above-mentioned collection unit 40 generates a vortex flow therein by the airflow passing through the inside, thereby collecting the abrasives having a r...

no. 3 example

[0153] As mentioned above, in reference to Figures 5 to 7 In the second specific example described above, although the dust collection unit 20 makes the working space 10a ventilate through the ventilation duct 10b and collects the abrasives through the collection unit 40 alternately, the collection of abrasives from the working space 10a can be combined with the above-mentioned dust collection unit 20. Ventilation of the working space 10a is performed simultaneously.

[0154] As a third specific example, refer to Figure 8 and Figure 9 An example configuration of the working chamber 1 configured in this way is described.

[0155] exist Figure 8 and Figure 9 In the specific example described in, in addition to the collection duct 41 ', cyclone 42 ' and exhaust duct 43 ', the collection unit 40' also has a dust collector 50 equipped with an exhaust fan 51, and the exhaust duct 43 ' communicate with the inlet of this dust collector 50.

Abstract

A dust collection unit 20 that ventilates a main unit 10 during blasting work and a ventilation unit 30 that ventilates a main unit during a painting step are provided by a blasting chamber. A side wall 11 of the main unit is provided with an entrance 11a and an opening-and-closing member 11b that opens / closes the entrance, the dust collection unit is provided so as to project from a roof panel 15 to a floor panel 16 at a position closer to an other side wall 12 that is opposed to this side wall so as to partition the interior of the main unit, and a working space 10a and a ventilation duct 10b are defined in the main unit. A roof panel 15 above a working space has air suction holes 17 formed therein, and an intake opening 22 that communicates between the dust collection unit and the ventilation duct is provided. The side wall is provided with an opening 12a that communicates between the ventilation unit and the ventilation duct, and during the blasting process, ventilation is conducted with the dust collection unit with the entrance closed, and during painting, ventilation is conducted with the ventilation unit with the entrance opened.

Description

technical field [0001] The present invention relates to a sandblasting chamber or working chamber (in this specification, simply referred to as "sandblasting chamber") for sandblasting process, and in particular, to a sandblasting chamber with a working space formed therein, The workspace is large enough that when a relatively large-sized workpiece to be processed is to be subjected to a blasting process, one or more workers can enter and work with the workpiece; and the workspace is adapted so that not only It is suitable for sandblasting and painting by allowing the sandblasting process and also allowing the workpiece to be painted in the same space after the sandblasting process. [0002] In the present invention, the term "blasting process" is used in the broadest sense; it includes various types of processes such as those known as dry blasting or projection (hereinafter referred to as "ejection", also including projection ) in which the abrasive is jetted in the form of ...
