Hard carbon black shaft end raw material oil gun

Abstract

The invention discloses a hard carbon black shaft end raw material oil gun. The hard carbon black shaft end raw material oil gun is characterized in that a gun head and a gun body can be separated andare connected through threads; a section of blind hole is formed in the gun head, the gun head and the blind hole are of an integrally-formed two-section structure, wherein the rear end part is a section of equal-diameter cylinder, and a section of internal thread is arranged in the equal-diameter cylinder and is in sealed threaded connection with the external thread of the gun body; and the other section is the front end part of the blind hole and the gun head, the front end part extends forwards from the front end part of the internal thread to gradually increase the size to form a blind hole chamber with the end surface of the closed end of the front end of the gun head shell, and the blind hole chamber is a raw material oil and compressed air mixing chamber. The oil gun has the following advantages that the raw material oil and compressed air mixing chamber is additionally arranged, so that raw material oil and atomized air are fully converged and mixed in the mixing chamber at the front end of the oil gun and then are sprayed into a furnace through the raw material oil gun head; and a spray gun hole of the gun head increases and enlarges the atomization angle, so that the atomization sectional area is increased, the atomization is more sufficient, the raw material oil reaction is more complete, then the carbon black coloring intensity is effectively improved, and the carbon black yield is increased.

Description

technical field [0001] The invention relates to an oil gun in the field of carbon black, in particular to a hard carbon black shaft end raw material oil gun. Background technique [0002] like Figure 1-2 As shown, the oil gun at the shaft end of the original technology is protected by jacket cold air, and there are few oil injection holes, and the angle of the gun head is small. Oil, single atomization pattern into the furnace. After injection, not only the atomizing air flow rate is insufficient, but also the raw material oil is not fully burned, and the role of fuel and reaction oil is not fully exerted. The working principle of the oil gun head: the raw oil enters through the rear end, the atomized air is used as the carrier, and is mixed with the compressed air to make the raw oil enter the furnace in the atomized mode through the angle specified by the design, and provide the reaction furnace for further processing. Burn and react. [0003] The patent 201720417664.7...

AI Technical Summary

Problems solved by technology

[0003] The patent 201720417664.7 applied by Tangshan Black Cat Company in 2017 is a raw material oil gun for the production of soft carbon black. The main technical problem to be solved is: poor atomization causes raw material oil droplets to drip on the reaction furnace, making local parts of the reaction furnace If the temperature is too high, the reaction furnace will be partially melted or burned through, which will reduce the service life of the reaction furnace, increase the replacement frequency of the reaction furnace, and increase the production cost

The patent 201520595225.6 applied by Wuhai Heimao Carbon Black Co., Ltd. in 2015 is a new type of carbon black fuel oil nozzle. Although it partially solves the problem that the atomization effect is not good and the large oil droplets produced cannot be fully burned, but its The defects are: 1. Only the fuel oil gun head has been improved. Now the fuel oil pipe in the equipment has a different way of feeding oil. The patented fuel oil gun head is no longer suitable for the existing equipment; The fuel oil gun head is damaged, and the fuel oil gun head is not easy to replace; 3. The mixing chamber is set in the gun head shell by the oil pipe, and the cavity formed between the closed end of the fuel pipe and the closed end of the gun head shell is the mixing chamber. The oil pipe is close to the gun head, if the temperature is too high, it is easy to penetrate and damage the oil pipe, and the oil pipe is too fast, the mixing chamber is too small, the combustion of the raw oil is not sufficient, and the atomization effect is still not good
