Definitions
- the design of the electric machine must include the operating conditions of the place where it will be installed; In the case of steps related to the mining production chain, for example, it is recommended that the equipment be fully protected against solid particles and liquid jets.
- the difficulty lies in the fact that the presence of an outlet for this liquid would allow solid particles and / or liquids to enter the enclosure. Another option would be that the housing is designed not to allow the presence of drains. However, there would be a need to periodically perform manual condensate removal operations from within the enclosure; This fact becomes an undesirable limitation regarding the operation of the machine, making it impossible to operate for long periods of time.
- US2002 / 0023686 discloses a drainage tube comprising a rubber body and a plastic connecting member; its lower end has a plurality of laterally extending water drainage openings opposite each other along the body of the tube.
- JP2011-103730 discloses a drainage cap inserted into the drainage hole consisting of an inner and outer cylinder, joined by a connecting plate.
- the present invention aims to circumvent the disadvantages in the state of the art, revealing a drainage system with a high degree of protection against solid and liquid particles, without the need for human intervention, reduced production costs, and the component itself.
- Figure 1 illustrates a sectional side view of the drainage body.
- Figure 2 illustrates a sectioned side view of a system embodiment.
- Figure 4 outlines the operation of the proposed system.
- Figure 5 illustrates a perspective bottom view of the system.
- the drainage system comprises a drainage body (1) coupled to the drainage hole (8) of the housing (2).
- the body (1) is made of an impermeable material and is provided with a hole (3) centrally positioned over the body (1), forming a hollow transverse inner channel (7), which will allow communication of the inner part. (A) of the housing with the outside (B) of the housing (2).
- the drainage body (1) should have a cylindrical geometry of dimensions compatible with the hole (3) and the channel (7).
- Some examples of materials used in the manufacture of the body (1) may be plastic, rubber or metallic material.
- a plurality of filaments (4) are positioned in the orifice (3), longitudinally traversing the channel (7) to convey the liquid to the outside of the housing (2) in the direction (A) to (B).
- Figure 3 shows a section of the system in a preferred embodiment in which the filaments (4) are intertwined.
- Another embodiment comprises the use of unbraided filaments (4).
- the structure of the filaments (4) will act as a filter element, preventing the penetration of solid particles and the entry of liquid inside the housing (2).
- the filaments or bristles (4) can be comprised of natural fibers ( 'such as cotton, jute, sisal, linen or silk) or synthetic (such as nylon, polyethylene, polypropylene, polyester or carbon fibers).
- the diameter of the central hole (3) should be slightly smaller than the total diameter of the filament assembly (4) to allow it to be firmly positioned, but may be equal to that of the filament assembly (4), provided it is fixed. by a binder.
- the filament may be surrounded by a collar (5) to facilitate the assembly process.
- Figure 5 illustrates a schematic of the developed drainage system in vertical drainage position.
- the condensed fluid (C) present in region (A) interacts with the portion (4a) of the filament assembly (4). Then the condensate (C) is eliminated in the lower portion (4C) of the filaments
- Figure 6 represents the lower portion (4C) of said filaments (4), in communication with the outer part (B) of the housing.
- the lower portion (4C) prevents particles from entering
