Abstract

The utility model relates to a scroll casing of a wind curtain machine, which comprises a scroll casing body, a through-hole and a removable cover board positioned on the front of the scroll casing body, and a built-in front edge processed at the periphery of the cover board. The height of the built-in front edge is equal to the thickness of the wall of the through-hole; steps are arraned at the periphery of the through-hole; an insertion head of a screwdriver is positioned between the cover board and the shell body; when in operation, the cover board and the shell body can be fixed with each other by screwing tight a screw; when in maintenance, the screwdriver is used for unscrewing the screw, the cover board is turned up, and a brush is directly inserted into the through hole to clean a wind wheel at the prior suspending position of the wind curtain machine directly, so that the labor cost for maintenance is simplified and saved, therefore, the scroll casing is applied to be used in various wind curtain machines.

Description

The wind curtain machine spiral case

Technical field

The utility model relates to wind curtain machine, especially a kind of wind curtain machine spiral case.

Background technique

Existing wind curtain machine spiral case is to be sleeved on the wind wheel outside; with the suction air-flow of wind wheel in the involute mode; boundling blows out through exhaust outlet, thereby realizes the purpose of high-speed air curtain, yet; the rotating speed of the general more tubular wind wheel of wind wheel that spiral case is built-in will exceed a lot; blast is also much bigger, after operation a period of time, the built-in wind wheel of spiral case usually can accumulation on thick dirt; time is long more; dirt is thick more, until stopping up the wind wheel blade gap, has had a strong impact on the effective wind speed of wind curtain machine; in order to safeguard the normal air-out of wind curtain machine; must remove the dirt on the wind wheel blade, still, because the spiral case and the wind wheel of existing wind curtain machine; motor is integrated being packed on the wind curtain machine base plate pedestal; must be with spiral case; wind wheel; the motor integral demounting comes out, and the parts decomposition is taken apart one by one again, could take out wind wheel and clean; obviously; this whole stationary spiral case exists difficulty to disassemble, and can't directly clean and clean wind wheel blade in the spiral case, and maintenance is extremely inconvenient; the shortcoming that maintenance cost is high, this is need be improved.

Summary of the invention

The utility model purpose is can directly implement to clean the wind curtain machine spiral case of wind wheel work in former mounting point for the wind curtain machine maintenance provides a kind of low cost simply to disassemble.

The utility model comprises the spiral case housing, be equipped with through hole and removable cover plate in spiral case housing front, around through hole, be shaped on external step, around cover plate, be shaped on built-in seam, built-in seam height equals the wall thickness of through hole, is equipped with bottle opener and inserts device between cover plate and housing.Cover plate and housing can be screwed into closely by screw and install, and behind screw-driving, the cover plate intrados becomes the smooth and easy curved surface of involute formula of same radian with the housing intrados.Neither can produce the retardance eddy current during running, can not produce leakage current yet, the same with conventional integrated type spiral case function, during maintenance, as long as open air curtain machine panel, the screw that installs that unclamps on the cover plate with bottle opener levers up the bottle opener device, just can take cover plate apart, directly passes through large-area through hole with brush, the wind wheel that is completely exposed is directly cleaned, after having cleaned, cover cover plate again, tighten screw, wind wheel in the wind curtain machine spiral case can turn round under the unstained condition of cleaning again, whole servicing operations is easy, no longer needs the integral body of former conventional volute wind curtain machine to unload from wall, the complex process of all disassembling.Save time cost, the dismountable spiral case of Ben Jianyi is adapted at using in the various wind curtain machines.

Fig. 1 is the utility model embodiment's a general structure schematic representation;

Fig. 2 is another angle general structure schematic representation of the utility model embodiment;

Fig. 3 is the utility model embodiment's a generalized section.

Embodiment

With embodiment and accompanying drawing the utility model is described in further detail below:

With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises spiral case housing 1, be equipped with through hole 2 and removable cover plate 3 in spiral case housing 1 front, around through hole 2, be shaped on external step 5, four inner edge sizes of external step 5 equal the size of limit all round of cover plate 3, around cover plate 3, be shaped on built-in seam 6, built-in seam 6 highly equals the wall thickness of through hole 2, on the cover plate limit between cover plate 3 and the housing 1, be equipped with bottle opener patchhole 4, cover plate 3 can be screwed into closely by the screw (not shown) with housing 1 and install, after the screw (not shown) is tightened, the smooth and easy curved surface of involute formula of 8 one-tenth same radians of cover plate 3 intrados 7 and housing 1 intrados, during running, neither the retardance eddy current can be produced, also leakage current can be do not produced; During maintenance, unclamp with bottle opener and to install screw, lever up bottle opener patchhole 4 again, just can take cover plate 3 apart, directly clean by the wind wheel (not shown) blade in 2 pairs of housings of through hole with brush tool, whole servicing operations can be finished at the former hanging position of wind curtain machine, easy saving of labor, and the dismountable spiral case of Ben Jianyi is adapted at using in the various wind curtain machines.

Certainly, insert device and be not limited to the foregoing description is shaped on the bottle opener patchhole on the cover plate limit a kind of concrete form being equipped with bottle opener between cover plate and the housing, also can adopt and on the housing limit, open the displacement format that is shaped on the bottle opener patchhole; In addition; install and the disassembled mode of cover plate and housing also be not limited to the foregoing description can by screw tight with a kind of mode of disassembling that specifically installs of unscrewing; also can adopt installing and disassembled mode of back-off hook and clasp, these formal arguments all fall into protection domain of the present utility model.

Claims
