Abstract
The invention discloses a fan protecting cover of a sand floating machine. The fan protecting cover comprises a fan and a support, wherein the fan and a switch are arranged on the support, the fan is fixed on the support through set screws, the switch is fastened on the support through screws, an air inlet and an exhaust port are formed in the fan and form a 90-degree angle, and a metal cover is arranged at the air inlet and is latticed. The fan protecting cover has a simple structure, risk to an operation worker is reduced, and the production benefits are increased.
Description
Technical field
The present invention relates to a kind of blower fan protective cover of floating sand machine, be applied to investment casting casing field.
Background technology
Floating sand machine is a kind of conventional hanging sand equipment in model casting industry, and in being, one of the complete smart casting machine of low temperature mould material, the wax-pattern that this kind of equipment is applicable in model casting hangs system two layers, backing layer molding sand.The wind that it is blown out by air blast blows on sand uniformly through a point pressing plate, sand must be formed the casting bed as the wave by wind, wax-pattern herein hanging sand is convenient and swift, but due to the kinetic energy that existing floating sand machine employing air blast provides sand to float rolling, in shell process processed, during different part shell, sand amount also can be different, and air blast is difficult to how much regulate pressure according to sand amount, workman is not shut down in production practices, air blast is worked long hours, cause air inlet can suck other impurity, the impurity sucked can cause the damage of air blast, thus increase the danger of operating personnel and reduce productivity effect.
Summary of the invention
The technical problem to be solved in the present invention is: the deficiency overcoming current condition, provides a kind of structure simple, increases the blower fan protective cover of the floating sand machine of operator safety.
The present invention is achieved in the following ways, a kind of blower fan protective cover of floating sand machine comprises: blower fan, support, described support is provided with blower fan, switch, described blower fan is fixed on support by fixed screw, and described switch is fixed by screw on support.
Described blower fan is provided with air inlet, exhaust outlet, described air inlet is located at the side of blower fan, and opposite side is provided with exhaust outlet, and described air inlet and exhaust outlet are 90 °.
Described air inlet is provided with metal cap, and described metal cap is screwed on air inlet, and described metal cap is latticed.
Described exhaust outlet connects the air inlet of floating sand bucket by ventilation duct.
The present invention has following obvious advantage and beneficial effect:
1) structure is simple, easy to use;
2) prevent impurity absorption from arriving in blower fan.
Accompanying drawing explanation
Fig. 1 is the structural representation of the blower fan protective cover of a kind of floating sand machine of this practicality.
Wherein: 1-blower fan; 2-support; 3-switch; 4-air inlet; 5-exhaust outlet; 6-metal cap.
Detailed description of the invention
As shown in Figure 1, a kind of blower fan protective cover of floating sand machine, comprising: blower fan 1, support 2, described support 2 is provided with blower fan 1, switch 3, and described blower fan 1 is fixed on support 2 by fixed screw, and described switch 3 is fixed by screw on support 2.
Described blower fan is provided with air inlet 4, exhaust outlet 5, described air inlet 2 is located at the side of blower fan 1, and opposite side is provided with exhaust outlet 4, and described air inlet 4 and exhaust outlet 5 are in 90 °.
Described air inlet 4 is provided with metal cap 6, and described metal cap 6 is screwed on air inlet, and described metal cap 6 is latticed.
Described exhaust outlet 5 connects the air inlet of floating sand bucket by ventilation duct.
The present invention is achieved in the following ways: be first energized to machine, then switch is opened, start working after blower fan energising, blower fan constantly sucks air by air inlet, exporting through exhaust outlet, by being fixed on the metal cap of air inlet, stop by the impurity adsorbed into exhaust outlet, thus play and prevent impurity to be inhaled in blower fan, damage is produced to blower fan.
Last it is noted that above embodiment only in order to illustrate the present invention and and unrestricted technical scheme described in the invention; Therefore, although this description with reference to each above-mentioned embodiment to present invention has been detailed description, those of ordinary skill in the art should be appreciated that and still can modify to the present invention or equivalent to replace; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in right of the present invention.
