Embodiment Construction

[0014] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a high-pressure gas pushes the projectile to remove slagging at the outlet of the rotary kiln. Magazine lock pin 8, magazine cover 9, high-pressure air duct 10, air compressor and pressure tank 11, control panel 12, air cylinder bracket 13, wheel locking system 14, brake pads 15, wheel bracket 16, wheels 17, overflow valve 18, electromagnetic one-way valve 19, loading magazine support 20, track 21, reversing valve 23, base plate 24 and spring 25 constitute. The tube body 1 is connected with the pneumatic cylinder 2, and the projectile 3 enters the loading chamber 6 through the loading funnel 7. Under the action of high-pressure gas, it is pushed into the tube body 1 and then ejected. The bullet funnel 7 is welded together by the welding port 26; the dial 4 and the pointer 5 are installed on the loading bin bracket 20 on the side of the loading bin 6, and the loading bin cover 9 is inserted ...

Abstract

The present invention discloses a device for using high pressure gas to drive a bullet to remove rotary kiln outlet slag, and the rotary kiln outlet slag can be removed safely and efficiently. The device comprises a pipe body, a pneumatic cylinder, the bullet, a dial, a pointer, a bullet loading bin, a bullet loading funnel, a bullet loading bin locking pin, a bullet loading bin cover, a high pressure air conduit, an air compressor, a control system, a pneumatic tank support, a vehicle wheel locking system, brake discs, vehicle wheel supports, vehicle wheels, an overflow valve, an electromagnetic one-way valve, a bullet loading bin support, tracks, another overflow valve, a reversing valve, a vehicle base plate, a spring, welded junctions, a bullet loading bin cover jack, a high pressure gas inlet and a bullet loading bin locking pin hole. During a slag removing process, internal environment quality of a rotary kiln is not influenced, the device has a certain distance from an outlet of the rotary kiln, hazards caused by manual slag removal of workers under high temperature environment and heavy manual labor can be prevented, and the device is prevented from being influenced by high temperature near the outlet of the rotary kiln is prevented.

Description

technical field [0001] The invention relates to a metallurgical mechanical device, in particular to a device for removing slagging at the outlet of a rotary kiln by pushing projectiles with high-pressure gas. Background technique [0002] Rotary kiln is one of the main equipment for producing pellets. The problem of slagging near the outlet of the rotary kiln has always been a major problem in actual production. Therefore, the removal of slagging near the outlet of the rotary kiln has a great impact on safe production and economic benefits. At present, there are some methods for removing slagging near the outlet of the rotary kiln, such as moving the combustion zone to burn off the slagging; manual slagging; rapid cooling method; mechanical scraper, etc. The above methods may damage the equipment, and the high temperature may also bring danger to the staff. Check related documents, patent publication (announcement) number: CN102654359A, titled "high-pressure hot air cutti...
