Preferably, the filter plate is made of quartz glass.

Preferably, the bottle body is of an integrally formed cylindrical structure, and the upper end and the side surface of the bottle body are connected in a circular arc shape

Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

the utility model relates to a waste discharge liquid receiving bottle at the furnace tail of a diffusion furnace, which comprises a bottle body, wherein a liquid inlet pipe and a liquid discharge pipe are arranged at the upper end of the bottle body, the liquid discharge pipe is arranged at the position, close to the lower part, of the side surface of the bottle body, and plays a certain cooling role, a filtering mechanism is also arranged in an inner cavity of the bottle, residues in tail gas can be left in the filtering mechanism by the filtering mechanism to prevent the liquid discharge pipe from being blocked, so that the subsequent work is difficult to carry out, the filtering mechanism comprises a plurality of filtering sheets, adjacent filtering sheets are arranged in parallel and are connected with each other, a plurality of filtering holes are formed in the filtering sheets, an exhaust pipe is arranged below the plurality of filtering sheets, the filtering efficiency can be increased by the plurality of filtering sheets, the filtering is cleaner, in addition, the cooling effect is increased, and the temperature of liquid or gas discharged by the liquid discharge pipe is reduced to a certain standard value.

Drawings

Some specific embodiments of the utility model will be described in detail hereinafter by way of example and not by way of limitation with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:

fig. 1 is a schematic structural view of a preferred embodiment of the present invention.

Wherein the reference numerals are as follows:

1. a bottle body; 2. a liquid inlet pipe; 3. a liquid discharge pipe; 4. a filter disc; 5. and a through hole.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1, the bottle comprises a bottle body 1, wherein the bottle body 1 is of a cylindrical structure, the upper end and the lower end of the bottle body 1 are connected with the two sides of the bottle body 1 through circular arcs, the whole bottle body 1 is of an integrally formed structure, the cylindrical structure and the circular arcs are connected to meet certain ornamental value, and meanwhile, the exhaust pipe is more convenient to pour waste liquid in the bottle body.

The liquid inlet pipe 2 is arranged in the middle of the upper end of the bottle body 1, is connected with the gas outlet device of the diffusion furnace and is used for receiving tail gas, the filtering mechanism is arranged in the cavity of the bottle body and comprises a filtering sheet 4, and the filtering sheet 4 is generally three-layer. Too few layers may result in incomplete filtration, which affects subsequent absorption, too many layers may result in too long filtration time, which affects waste gas discharge, and also results in overcrowding in the bottle body 1, which requires frequent cleaning and replacement. The filter discs 4 are quartz glass mechanisms, adjacent filter discs 4 are connected through a quartz connecting column, and the adjacent filter discs 4 are arranged in parallel and are relatively uniform in interval. The filter sheet 4 is provided with a plurality of through holes 5. The first layer and the third layer of filter discs 4 are connected with the bottle body through the quartz connecting columns, so that the direct connection with the bottle body and the direct welding with the bottle body are avoided, and the bottle body is likely to be cracked due to the overlarge contact area. The spliced pole between adjacent cassette 4 and the spliced pole between cassette 4 and the body 1 all are provided with a plurality ofly, and the former guarantees that the connection between the cassette is inseparable, and the latter guarantees that filter equipment is inseparable with being connected of body, prevents to drop.

The liquid discharge pipe 3 is arranged on the side wall of the bottle body 1 and is positioned below the filter 4, and has the functions of cooling, exhausting, discharging liquid and the like.

During the specific use, tail gas has the entering of feed liquor pipe 2, and through filter equipment's multiple-layer filtration and cooling, can condense into liquid or solid, leave over in the body inner chamber, and fluid-discharge tube 3 is used for gaseous discharge and the cooling of body, still is used for the discharge of its interior liquid.
