Problems solved by technology

[0003] aims at secondary fuel utilization of coal tar, an auxiliary product of coal chemical industry. In this process, coal tar is injected and burned through the spray gun nozzle, but the existing spray gun atomization effect Good, and in the coal tar combustion process, it is very easy to generate carbon deposits in the front of the nozzle of the spray gun. The carbon deposits are adsorbed and scaled in the nozzle, which affects the work effect and quality. It is necessary to disassemble the nozzle for cleaning, which increases the workload of workers and reduces work efficiency. How to solve this technical problem has become the direction of efforts of those skilled in the art

Abstract

The invention discloses an adjustable spray gun, and relates to the technical field of spray guns. The technical problems that in an existing coal tar combustion process, deposited carbon can be easily generated in a spray nozzle of a spray gun, and the combustion effect is affected due to insufficient atomization are solved. The adjustable spray gun comprises a hollow rod body, wherein an oil inlet and a compressed air inlet are formed in the hollow rod body, and the right end of the hollow rod body is connected with a spray nozzle nut; an adjusting rod is arranged in the hollow rod body, a gap exists between the hollow rod body and the adjusting rod, a spray core is connected to the end, arranged in the hollow rod body and close to the spray nozzle nut, of the adjusting rod, four flow guiding spirals are arranged on the spray core, and the end, far away from the spray nozzle nut, of the adjusting rod stretches out of the hollow rod body, and is connected with a handle; a sealing assembly is arranged at the left end of the hollow rod body, the adjusting rod is located by the sealing assembly in a sealed mode, and the adjusting rod can rotate in the hollow rod body through the handle. The adjustable spray gun has the advantages that the structure is simple, carbon cannot be easily deposited in the spray nozzle, atomization is sufficient, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of spray guns, in particular to an adjustable spray gun. Background technique [0002] coal tar is coking One of the important products of the industry, its composition is extremely complex, and in most cases it is specially separated and purified by the coal tar industry for utilization. Coal tar is also called coal paste, coal distillate, and coal tar solution. yes Coal coking A black or dark brown viscous liquid obtained during the process, the specific gravity is greater than water, has certain solubility and special odor, is flammable and has Corrosive , coal tar is coking industrial coal Pyrolysis One of the products in the generated crude gas, its output accounts for about 3%~4% of the furnace coal. Temperature and pressure The product is black viscous liquid, and coal tar can be used as fuel for secondary utilization. [0003] Coal tar, an auxiliary product of the coal chemical i...
