Technical Field

The invention relates to the technical field of spraying production, in particular to an access door.

Background

In the process of processing and manufacturing metal, in order to prolong the service life of a metal product and enable the metal product to have better corrosion resistance and also to achieve an aesthetic effect, a spraying process is often adopted to spray a decorative coating layer on the surface of the metal. However, during the processing, storage or transportation of the semi-finished metal workpiece, the surface of the semi-finished metal workpiece is often contaminated by oil stains or generates an oxidized rust layer, and the contaminants or the oxidized rust layer affect the spraying effect, so that the coating layer is not firmly adhered to the metal surface and is easy to fall off, or particles, bubbles and the like are generated in the coating layer. Therefore, before the metal workpiece is subjected to the spraying process, the surface of the metal workpiece needs to be subjected to a cleaning pretreatment to remove pollutants or an oxidation rust layer on the surface of the metal workpiece, i.e., the spraying pretreatment.

The spraying pretreatment process is generally carried out in a spraying tunnel, and high-pressure spraying liquid or corrosive liquid is usually adopted in the spraying tunnel to clean the surface of a metal workpiece, so that the spraying tunnel is required to have good sealing property so as to prevent the spraying liquid from leaking outwards and polluting a working space. In order to facilitate checking the working condition of equipment in the spraying tunnel and facilitating maintenance, an access door can be arranged on the side wall of the spraying tunnel. The door body structure of conventional access door is planar structure, like this, when spraying liquid splashes on the access door in a large number, sprays liquid and can not flow down from the interior door face in time, gathers the spraying liquid on the access door and can outwards ooze from the crack.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment of the invention provides an access door which is structurally shown in figures 1-7. The utility model provides an access door, includes door plant main part 1, is equipped with a plurality of recesses 2 on the interior face of door plant main part 1, is equipped with an overflow hole 3 in every recess 2, and every overflow hole 3 is linked together with the inside water conservancy diversion passageway 4 of seting up of door plant main part 1, and water conservancy diversion passageway 4 is used for the liquid water conservancy diversion that flows in the overflow hole 3 to door plant main part 1 outside.

During the use, with the access door of this embodiment through articulated hinge fixed connection on the lateral wall that sprays the tunnel, after the equipment that sprays in the tunnel work, it can splash on the interior face of access door to spray liquid, through be equipped with a plurality of recesses 2 on the interior face of door plant main part 1, be equipped with an overflow hole 3 in every recess 2, every overflow hole 3 is linked together with the inside water conservancy diversion passageway 4 of seting up of door plant main part 1, when a large amount of liquid that sprays when splashing on the interior face of door plant main part 1 like this, the part sprays liquid and flows down along interior face, another part sprays in liquid gets into overflow hole 3, get off through the water conservancy diversion passageway 4 water conservancy diversion. The access door can quickly guide a large amount of spraying liquid splashed on the inner panel surface of the access door, and prevent the spraying liquid from being leaked due to the accumulation of the spraying liquid on the inner panel surface of the door panel main body 1.

Preferably, the air guide passage 4 is provided in plurality inside the door panel main body 1, as shown in fig. 1, 2, 6, and 7. Spray liquid splashed into the overflow holes 3 can be quickly guided out through the guide channels 4, and the spray liquid is prevented from accumulating on the inner plate surface of the door plate main body 1. More preferably, the plurality of diversion channels 4 are communicated with each other, as shown in fig. 2, so that the spraying liquid overflowing into the diversion channels 4 can automatically flow into the most unblocked path inside the door panel main body 1, and further, the excessive spraying liquid can be quickly diverted out.

Preferably, the groove 2 is flared, as shown in fig. 1-4. The horn-mouth-shaped groove is beneficial to the spraying liquid splashed on the surface of the groove 2 to drop along the arc-shaped surface of the groove, and the spraying liquid is beneficial to rapidly flow down from the inner plate surface of the door plate main body 1; on the other hand, when spraying the inside that the liquid splashed recess 2 in a large number, the overflow hole of throat form can with spray in the liquid water conservancy diversion passageway 4 fast, like this through the quick water conservancy diversion effect of double, prevent to spray liquid and gather on the interior face of door plant main part 1, effectively prevent to spray the crack department exosmosis of liquid through door plant main part 1.
