Problems solved by technology

[0003] At present, it can be used in the semi-solid medium dispersion conveying device. If there is a slime feeder, it is generally composed of a feeding cylinder seat, a piston ring, a compressed air rod, etc. The feeding cylinder seat has a horizontal feed port and a horizontal discharge. The piston ring has three working sections, through which the semi-solid medium of coal slime can be transported to the kiln for processing. This equipment can complete the transportation of coal slime. However, during the transportation process, blockage also occurs, and the equipment is not suitable for cleaning

Embodiment 1

[0051] Example 1: sludge incineration

[0052] Sludge generally contains a lot of sundries, and it is unavoidable. Before the sludge is pumped into the spray gun, the sundries in it are filtered and stored in the sundries collection cylinder outside the spray gun.

[0053] After the sludge enters the spray gun, it flows from the gap between the compressed air rod in the middle of the spray gun and the inner wall of the spray gun to the outlet of the spray gun, and before approaching the exit, the flow rate increases due to the narrowing of the gap, and at the same time, it is compressed by the external compressed air. As far as possible, it is in a dispersed state when it is discharged.

[0054] The dispersed sludge in the incineration system will help improve the combustion efficiency, so as to achieve the purpose of more energy saving and more thorough incineration.

[0055] If the spray gun is used to incinerate sludge in a cement kiln, practice has proved that due to the ...

Embodiment 2

[0058] Embodiment 2: comprehensive utilization of coal slime

[0059] Coal slime generally also contains more sundries, and it is unavoidable. Before the sludge is pumped into the spray gun, the sundries therein are filtered and stored in the sundry collection cylinder outside the spray gun.

[0060] After the coal slime enters the spray gun, it flows from the gap between the compressed air rod in the middle of the spray gun and the inner wall of the spray gun to the outlet of the spray gun, and before approaching the exit, the flow rate increases due to the narrowing of the gap, and at the same time, it is affected by the compressed air supplied from the outside. As far as possible, it is in a dispersed state when it is discharged.

[0061] The coal slime in a dispersed state will help improve the combustion efficiency in the boiler system, so as to achieve the purpose of more energy saving and sufficient combustion.

Abstract

The invention discloses a spray gun and a method for dispersively delivering a semi-solid medium through utilizing the spray gun. A material connecting port is formed in a spray gun body, a compressed air rod is arranged in an inner cavity of the gun body and consists of an inner dispersing pipe and a piston ring which is sleeved on the inner dispersing pipe, the inner dispersing pipe can laterally move in the gun body, a clamping head is sleeved on the rear section of the inner dispersing pipe, an atomizing air port, a cleaning water port and an inner atomizing ring cooling air port are formed in the tail end of the inner dispersing pipe, and an atomizing ring is buckled on the front end (the end which is close to an incineration port) of the inner dispersing pipe; a retaining ring is arranged on the inner cavity wall of the gun body and is positioned in front of the piston ring; an actuator is arranged, one end of the actuator is stably connected with the gun body, the actuator is provided with a push rod which can do reciprocating motion, the outer end of the push rod of the actuator is fixedly connected with the tail end of the inner dispersing pipe and can drive the inner dispersing pipe to do lateral reciprocating movement; and a spray gun cleaning connecting port is formed in the gun body. The spray gun can reasonably disperse semi-solid materials, and the delivering is quicker and more efficient .

Description

technical field [0001] The invention relates to an atomization and dispersing device for a semi-solid medium and a method thereof, in particular to a spray gun and a method for dispersing and conveying a semi-solid medium by using the spray gun. Background technique [0002] With the development of environmental protection technology, especially the requirements of the current circular economy, traditional wastes such as coal slime, industrial and municipal sludge produced by coal mine washing are being comprehensively utilized or finally disposed of through different kilns. . In this process, materials need to be properly dispersed in order to be fully utilized or disposed of. [0003] At present, it can be used in the semi-solid medium dispersion conveying device. If there is a slime feeder, it is generally composed of a feeding cylinder seat, a piston ring, a compressed air rod, etc. The feeding cylinder seat has a horizontal inlet and a horizontal outlet. The mouth and...
