Mixer with retractable exhaust funnel

Abstract

The present invention disclose a mixer with retractable exhaust funnel, including mixing barrel, gas skirt and exhaust funnel set vertically, the gas skirt is arranged on discharge end of the mixing barrel, one end of the exhaust funnel is connected with the gas skirt, another end extends to top of workshop, the exhaust funnel includes retractable section and two fixed sections, one of the fixed section is connected with the retractable section, the other fixed section is connected with the retractable section via connector. The mixer with retractable exhaust funnel is provided with advantagesof keeping the exhaust funnel discharging smoothly, the exhaust funnel is retractable for temporary, providing convenient condition for overhaul vehicle passing in work shop, and being able to stretch and recovering mounting in time, will not affect normal work.

Description

technical field [0001] The invention relates to material mixing equipment in the metallurgical industry, in particular to a mixer with a retractable exhaust cylinder. Background technique [0002] Existing mixers used in the metallurgical industry are mainly used for mixing various materials after sintering and batching, and making the sintered materials into spherical particles. Such as figure 1 and figure 2 As shown, in order to facilitate inspection and maintenance, this kind of mixer is usually installed in a workshop with a crane. Its main working part is a horizontal cylindrical mixing drum 1 with a certain inclination angle. The higher end enters, and the rotation of the mixing cylinder 1 drives the mixed material to roll in the cylinder, so that the material is gradually mixed during the rolling and forms spherical particles. In the mixer, the spheroidization rate of the mixture directly affects the air permeability of the sintered material layer during the sinte...

Problems solved by technology

Although this method avoids the interference between the exhaust tube 3 and the truck 5, dust is easy to accumulate in the curved exhaust tube 3, which affects the emission effect, especially after quicklime and water are added to the mixture, the dust has a large Strong stickiness, it is very easy to stick to the bending part of the exhaust pipe 3. Usually, it will cause the exhaust pipe 3 to be blocked in about two months, resulting in the natural release of dusty smoke and deterioration of the production environment, thereby The exhaust tube 3 had to be cleaned or replaced as a whole, which also made the mixer unable to work normally; at the same time, the crane beam must be arranged above the oblique extension of the exhaust tube 3, and it had to be installed in the design of the factory building. By increasing the height of the factory building, there is room for the installation of the exhaust pipe 3, thereby causing an increase in the construction cost of the factory building

At present, some manufacturers arrange the exhaust pipe vertically. Although this method can avoid the bending structure of the exhaust pipe, prevent the exhaust pipe from being blocked, and improve the emission effect, the vertically arranged exhaust pipe will inevitably affect the traffic of the vehicle. , and the existing exhaust pipes are all integral structures, which cannot be quickly disassembled to make room for the traffic of the traffic. The cost of this configuration is too high; some manufacturers choose to install two monorail cranes instead of driving. Although this method does not require too much cost while improving the emission effect, the monorail crane has limited carrying capacity and cannot handle many heavy equipment. Hoisting cannot meet the configuration requirements of the mixer plant
