Abstract
The utility model relates to a new discharge structure of slack coal steam tube revolving cylinder drier, with structure characterized in that arrange 6-8 discharge ports along cylinder circumferential direction on discharge terminal of the steam tube revolving cylinder drier; set a material guide port along discharge port edge with size same; the material guide port is provided with a flange which are connected with barrel on edge of the discharge port by bolts; forepart of the discharge port is provided with a material retaining ring; and the drier cylinder is provided with a dabber. At least 3 discharge ports in the utility model discharge in revolving cylinder rotate process, discharge capability is enhanced, slack coal discharge volume can be more than 600t/h, and can be discharged smoothly. Compared with center discharge structure of the existing steam tube revolving cylinder drier, structure of drier steam dome is simplified greatly, which is beneficial to smooth entering of dry steam and discharging of lime set, improves drier handling ability and reduces equipment fabrication cost.
Description
Technical field
The utility model relates to a kind of discharging structure of novel fine coal steam pipe revolving drum drier.
Background technology
At present, the discharging structure of steam pipe revolving drum drier commonly used adopts the center discharge method in the industry, center drawing mechanism design is with discharging portion circle of position tube undergauge, the guide ribbon is set then, complex structure, and discharge channel diminishes behind the undergauge, unloading performance reduces, and prolong the distance of discharging, this type of discharging structure is applicable to the less (occasions such as output≤150t/h), high-moisture material, and sealing device is strict of output.And that the characteristics of fine coal drying are dryer capacities is big (generally equal 〉=more than the 200t/h), evaporation water intensity height, and the material after being dried should be discharged timely, otherwise can cause the fine coal super-dry, cause the fine coal blast, and the pulverized coal particle after the super-dry easily reveals, and hermetically-sealed construction is had relatively high expectations.So the center discharging structure of steam pipe revolving drum drier commonly used is not suitable for the fine coal steam-tube rotatory dryer.
Summary of the invention
For the center discharging structure that overcomes steam pipe revolving drum drier commonly used limits in the application of fine coal drying, the utility model proposes a kind of fine coal steam pipe revolving drum drier discharging structure, promptly at steam pipe revolving drum drier discharge end position, along cylinder is circumferentially uniform 6～8 discharge ports are set, discharge port is a square structure, at the discharge port edge material guide port is set, discharges smoothly after the adaptation fine coal drying.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of fine coal steam pipe revolving drum drier discharging structure is made up of blocking material ring, cylinder, discharge port, material guide port, heat exchanger tube, steam chest, reinforcement.At steam pipe revolving drum drier discharge end position, 6～8 discharge ports are set along cylinder is circumferentially uniform, at the discharge port edge material guide port is set, the material guide port size is identical with discharge port, and material guide port is provided with flange, with bolt the cylinder of flange with the discharge port edge is connected; The material guide port flange is taken over along the side of the height that 200mm～300mm is set, and the discharge port leading portion is provided with blocking material ring (overflow weir), is equipped with reinforcement on the drying machine cylinder.
Above-mentioned discharge port is a square structure.
The beneficial effect of advantage of the present utility model and generation is:
Discharging structure of the present utility model has the discharging simultaneously of 3 discharge ports at least in the revolving drum rotation process, unloading performance strengthens, and fine coal discharging amount can reach more than the 600t/h, all can discharge smoothly.Compare with existing steam pipe revolving drum drier center discharging structure, simplified the structure of drying machine steam chest greatly, help entering smoothly and the smooth and easy discharge of lime set of dry steam, increased the disposal ability of drying machine, reduced the cost of equipment.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further again:
As shown in Figure 1, a kind of fine coal steam pipe revolving drum drier discharging structure is made up of blocking material ring 1, cylinder 2, discharge port 3, material guide port 4, heat exchanger tube 5, steam chest 6, reinforcement 7.At steam pipe revolving drum drier discharge end position, circumferentially all lay 8 discharge ports 3 along cylinder, discharge port is the square structure (see figure 2), the size of mouth is determined according to the fine coal treating capacity, at the discharge port edge material guide port 4 is set, material guide port 4 sizes are identical with discharge port 3, and material guide port 4 is provided with flange, with bolt flange is connected with the cylinder 2 at discharge port edge.The material guide port flange is taken over along the side of the height that 300mm is set, and is convenient to fine coal and discharges smoothly in the process of drying machine rotation, and guide effect is played in the discharge of fine coal, can effectively prevent the leakage of fine coal.Cylinder discharge port 3 leading portions are provided with blocking material ring 1 (overflow weir), guarantee the filling rate and the time of staying of fine coal in drying machine of fine coal in the drying machine; Heat exchanger tube 5 passes blocking material ring 1, and pore is arranged according to the arrangement of heat exchanger tube 5, and the outer ring of blocking material ring 1 and the welding of drying machine cylindrical shell inwall are fixing, and the inner ring aspect ratio exceeds 150mm near the set of heat exchange tubes at cylindrical shell center, guarantee that fine coal is full of the heat exchanger tube 5 of cylindrical shell bottom, improve heat transfer efficiency.In drying machine cylinder 2 rotary courses, the fine coal that is dried is crossed blocking material ring 1 along drying machine gradient direction, along discharge port 3, through material guide port 1 discharge.Need to carry out reinforcement after 2 perforates of drying machine cylinder, can adopt design reinforcement 7 (or increasing wall thickness of cylinder or the outer liner plate of design cylinder) to carry out reinforcement.
