Specific embodiment

The utility model embodiment discloses a kind of waste discharge feed channel, unsmooth to efficiently solve waste discharge feed channel drain Problem.

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to the structural schematic diagram that Fig. 1-Fig. 2 Fig. 1 is waste discharge feed channel provided by the embodiment of the utility model；Fig. 2 is The axial arrangement schematic diagram of waste discharge feed channel provided by the embodiment of the utility model.

In a specific embodiment, this implementation provides a kind of waste discharge feed channel, to be used for semiconductor, electronics and light The biggish exhaust gas discharge of the humidity that the industries such as volt generate in the fabrication process.General waste discharge tracheae can carry out one depending on the site environment Fixed curved arrangement up and down, but can at least have one end horizontal pipe section 1, and discharge outlet 3 is provided at horizontal pipe section 1, with The water discharge assembled in by exhaust piping.

In the waste discharge feed channel of the present embodiment, it is also provided with pipeline from top to bottom and is in the catheter 2 of gradual shrinkage, i.e. pipeline Cross-sectional area be gradually reduced from top to bottom, and be preferably continuously reduced, such as pyramid type.For the structure of catheter 2, a kind of tool The structure of body, it is in horn-like for can making catheter 2, and big opening end is upward, and osculum end is downward.

Wherein the upper end of catheter 2 is located on 3 lower port face of discharge outlet, so that can from the liquid that discharge outlet 3 is discharged It is fully contemplated in catheter 2, and is bonded and is tightly connected on the downside of the upper end end face of catheter 2 and horizontal pipe section 1, to avoid liquid Junction outflow of the body after the discharge of discharge outlet 3, between catheter 2 and horizontal pipe end.

Wherein the liquid in catheter 2 is passed through drain pipe 4 for connecting with drain pipe 4 by the lower end nozzle of catheter 2 Discharge.It should be noted that the lower end nozzle of catheter 2 specifically how with 4 direct or indirect connection of drain pipe, can be with reference to existing Have in technology, how to be attached two pipe fittings.

Wherein the flow area of the lower end nozzle of catheter 2 is less than the flow area of discharge outlet 3, certainly because of catheter 2 Upper end be located at the 3 lower port face of discharge outlet, so the upper end tube nozzle flow area of catheter 2 should be not less than discharge outlet 3 flow area.So that increasing the flow area of discharge outlet 3, Neng Gouyou on the basis of not changing the flow area of drain pipe 4 Effect ground facilitates liquid to flow out from discharge outlet 3.It should be noted that when above-mentioned flow area refers to liquid flowing, perpendicular to The section gross area of flow direction, such as mesh channel, the cross-sectional area summation in as each channel.

In the present embodiment, in the application waste discharge feed channel, after cohesion has a large amount of water in horizontal pipe end, water can be from Discharge outlet 3 is discharged, and enters in catheter 2, and then flow out in drain pipe 4 from catheter 2, with discharge, and when drain pipe 4 When the velocity of discharge is smaller, water is just saved bit by bit in catheter 2 at this time, and because 2 upper end tube nozzle of catheter increases, cavity volume increases Greatly, so that the liquid in waste discharge feed channel can continue in catheter 2, to avoid waste air line clogging, in addition, with Liquid in catheter 2 increase, certain pressurization power can be formed to 2 lower end of catheter, can effectively accelerate lower end nozzle Drain age velocity, and then hydrops amount can be effectively reduced.The flow area for increasing outlet, is arranged as early as possible conducive to horizontal pipe section 1 Liquid out, and catheter 2 is set, the liquid that outlet can not only be facilitated to be discharged flows to lower end as early as possible, while being tied using itself The characteristic of structure is pressurizeed conducive to the lower end nozzle to catheter 2, to accelerate 4 drain of drain pipe.In conclusion the waste air Pipeline can efficiently solve the unsmooth problem of waste discharge feed channel drain.

As described above, 2 pipeline of catheter is in gradual shrinkage from top to bottom, in order to facilitate gas flowing, with preferably under The pressurization of end pipe mouth, preferably 2 pipeline of catheter is in continuous gradual shrinkage from top to bottom, to facilitate gas to flow.Wherein 2 pipeline of catheter Cross section can be square or triangle, connect for convenience, herein the circular in cross-section of preferred 2 pipeline of catheter, with Facilitate molding catheter 2.

2 pipeline of catheter as described above is in gradual shrinkage from top to bottom, in order to guarantee liquid storage capacity and preferably pressurization, The upper end tube nozzle flow area of middle catheter 2 is not less than twice of the flow area of lower end nozzle, specifically, leading as above-mentioned When 2 conduit cross-sectional area of liquid pipe is rounded, preferred 2 pipeline upper end diameter of catheter is not less than twice of lower end diameter herein, It should be noted that be based on this because 1 caliber of horizontal pipe section is limited, be provided at preferred discharge outlet 3 with multiple through-holes herein Orifice plate, which is fixedly connected with horizontal pipe section 1, to play the role of reinforcement.In order to facilitate manufacture, herein preferred orifice plate with Horizontal pipe end is integrally formed and entirety is in cylindrical tube.It can be drilled out in the part of setting discharge outlet 3 more on a pipeline A through-hole, to form drainage hole.Should be disposed on specific orifice plate it is multiple be uniformly distributed and through-hole cylindrical, using circle Post holes can be convenient molding.

Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other The difference of embodiment, the same or similar parts in each embodiment may refer to each other.

The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest scope consistent with features of novelty.
