Technical Field

[0001] The utility model relates to the field of carbon black production devices, in particular to a binder adding device for carbon black granulation. Background Art

[0002] Carbon black is a kind of amorphous carbon. It is a light, loose and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition under insufficient air conditions. Carbon black has a wide range of applications. It can be used as a black dye, used in the manufacture of inks, paints, etc. It is also used as a reinforcing agent for rubber and plays an important role in the industrial field.

[0003] In the production process of carbon black, in order to make the carbon black better granulated in the subsequent granulation process, it is necessary to spray a binder into the carbon black flue gas. However, the atomization effect of the binder is not good, which affects the production quality and efficiency of carbon black. Utility Model Content

[0006] Furthermore, the inlet pipe is provided with an inlet valve, the outlet pipe is provided with an outlet valve, the outlet pipe is also connected to a return pipe, the return pipe is equipped with a return valve, and the end of the return pipe is connected to the top of the adhesive pool.

[0007] Furthermore, the compressed air pipe is provided with an automatic control valve, and three jet pipes are provided from top to bottom, and the jetting direction of each jet pipe is opposite to the conveying direction of the adhesive.

[0008] Furthermore, the variable diameter valve is in a "trumpet" shape, and is a structure that is narrow in the middle and wide on both sides. A first end face is provided at the left end of the variable diameter valve, and a second end face is provided at the right end of the variable diameter valve, and the diameter of the first end face is smaller than the diameter of the second end face.

[0009] Furthermore, a nozzle is provided at the end of the air injection pipe.

[0010] Furthermore, a hollow channel is provided inside the nozzle for the adhesive to pass through. The nozzle is arranged in a horizontal direction. A first spray hole is provided at the left end of the nozzle. Four second spray holes are provided on the right side of the first spray hole. The four second spray holes are symmetrically arranged.

[0011] Compared with the prior art, the utility model has the following advantages: the device adds an air jet pipe to the compressed air pipe, and a nozzle is arranged on the air jet pipe. The spraying direction of the nozzle is opposite to the conveying direction of the adhesive. The compressed air is sprayed from the nozzle, which can make the adhesive obtain a better atomization effect.

[0019] Those skilled in the art will understand that, in general, the terms used herein, and particularly in the appended claims (e.g., the bodies of the appended claims), are often interpreted as "open-ended" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "comprising" should be interpreted as "including but not limited to," etc.). Those skilled in the art will also understand that if a specific number of an introduced claim recitation is intended, such intent will be explicitly recited in the claim, and in the absence of such a recitation, such intent is not present. For example, as an aid to understanding, the appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that a claim recitation introduced by the indefinite article "a" or "an" limits any particular claim containing such an introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrase "one or more" or "at least one" and an indefinite article such as "a" or "an" (e.g., "a" and / or "an" should be construed to mean "at least one" or "one or more"); the same applies to the use of definite articles used to introduce claim recitations.
