Abstract
The utility model discloses an etching tank, and the outer wall of the tank comprises four outer side walls surrounding the inner wall of the tank and an outer bottom wall, wherein every two adjacent outer side walls are fixedly connected, each outer side wall is fixedly connected with the outer bottom wall, at least one outer side wall is rotatable, the fixed connections of the rotatable outer side wall, the adjacent outer side walls and the outer bottom wall are detachable, and a hinge part is arranged on the connection portion of the rotatable outer side wall and one adjacent outer side wall. The etching tank of the utility model adopts open door type structure, thus the operation is more convenient.
Description
Technical field
The utility model relates to a kind of etching tank.
Background technology
At chemical field, need use etching tank when particularly silicon oxy-nitride material is carried out corrosion reaction to material.The corrosive fluid of etching tank institute splendid attire has stronger corrodibility, toxicity usually, so etching tank generally is made as open-topped groove, it has an acid proof groove inwall and fixedly covers groove outer wall outside the groove inwall.For preventing that corrosive fluid from leaking, the groove outer wall comprises outer side wall (generally comparatively firm) and exterior bottom wall of four circumferential groove inwalls, and is fixedly connected between every two adjacent outer side walls, is fixedly connected between each outer side wall and the exterior bottom wall.And be placed with some relative unit, parts, material etc. in the etching tank in addition, need often to change, and operate pretty troublesome from the open top taking-up.
Summary of the invention
For solving above-mentioned technical problem, the utility model provides a kind of etching tank of being more convenient for operating, its groove outer wall comprises outer side wall and exterior bottom wall of four circumferential groove inwalls, be fixedly connected between every two adjacent outer side walls, be fixedly connected between each outer side wall and the exterior bottom wall, wherein has a rotating outer side wall at least, the fixedly connected of the outer side wall that described rotating outer side wall is adjacent, described exterior bottom wall is demountable, and the junction of the rotating outer side wall outer side wall adjacent with one of them also is provided with a hinge portion
Adopt the etching tank of technique scheme, at least be provided with a rotating outer side wall, this outer side wall and adjacent outer side wall, fixing can the dismounting between the exterior bottom wall, and be provided with one can so that this outer side wall relative to hinge portion that one of them outer side wall that is adjacent rotates, etching tank of the present utility model adopts side opening door structure, more convenient operation.
Be folded with gasket seal between two outer side walls that described rotating outer side wall is adjacent.
Described hinge portion is a spring hinge portion.
Describedly be fixedly connected as bolted mode.Also can adopt other fixedly connected modes known in the art.
Description of drawings
Accompanying drawing 1 is the schematic top plan view of the utility model etching tank;
11,12,13,14, outer side wall; 31,32, mounting block; 4, hinge portion; 5, gasket seal.
Embodiment
Below in conjunction with drawings and Examples the utility model etching tank is specifically described.
Embodiment 1
Accompanying drawing 1 is the structure iron of the utility model etching tank.Referring to Fig. 1, a kind of etching tank, its groove outer wall comprises 11,12,13,14 and exterior bottom wall of outer side wall of four circumferential groove inwalls, be fixedly connected between every adjacent two outer side walls 11,12,13,14, be fixedly connected between each outer side wall 11,12,13,14 and the exterior bottom wall, as shown in Figure 1, mounting block 31,32 adopts bolt connecting mode.
A rotating outer side wall 11 is wherein arranged, the fixedly connected of outer side wall 11,12 that described rotating outer side wall 11 is adjacent and exterior bottom wall is demountable (being that mounting block 31 is demountable), and the junction of rotating outer side wall 11 outer side wall 12 adjacent with one of them also is provided with a hinge portion 4.
As shown in Figure 1, be folded with gasket seal 5 between two outer side walls that rotating outer side wall is adjacent.
As shown in Figure 1, hinge portion 5 is a spring hinge portion.
