Abstract
A vertical powder feeding machine comprises a worm gear speed reducer, a feeding impeller and a measuring impeller, wherein the feeding impeller and the measuring impeller are driven by the worm gear speed reducer to rotate; a worm gear main shaft of the worm gear speed reducer extends out downwards; the feeding impeller and the measuring impeller are fixedly connected with the worm gear main shaft in sequence to form a vertical structure suspended on the worm gear main shaft; the upper part of the worm gear main shaft is of an m-shaped structure; the lower end cover of the worm gear speed reducer is of a U-shaped structure; the U-shaped structure of the lower end over extends into the m-shaped structure of the worm gear main shaft to form a vertical shaft seal. The vertical powder feeding machine has the advantages that a motor and the worm gear speed reducer are positioned above the feeding impeller, so that a worm gear, a worm and a bearing of the worm gear speed reducer are always immersed in oil for sufficient lubrication; the feeding impeller and the measuring impeller of the vertical powder feeding machine are suspended on the worm gear main shaft; the vertical powder feeding machine has triple-sealing shafts, so that coal powder can be reliably sealed. The principle that oil in the worm gear speed reducer can never be leaked relies on the centrifugal force and gravity, that is, the oil cannot be leaked in the presence of the centrifugal force and gravity.

Summary of the invention
Object of the present invention is just to provide a kind of worm gear of worm reduction gear, worm screw, bearing are always immersed in oil, obtains sufficient lubrication; Supply impeller and the measurement impeller of machine supplying powder are suspended on worm-wheel shaft; Machine supplying powder sealing has 3 roads, can positiver sealing coal dust.In worm reduction gear, oil leaks never, and principle is by centnifugal force and terrestrial attraction, as long as these two power exist the vertical machine supplying powder that oil just cannot spill.
Solution of the present invention is such:
A kind of vertical machine supplying powder, comprise worm reduction gear and by worm reduction gear driven rotary supply impeller and measure impeller, it is characterized in that: the worm gear main shaft of described worm reduction gear stretches out downwards, described supply impeller and measure impeller successively with under the worm gear main shaft that stretches out be fixedly connected as the vertical structure be suspended on worm gear main shaft.
Technical scheme also comprises more specifically: described worm gear main shaft top is the structure of falling Ψ, and worm reduction gear bottom end cover is U-shaped structure, and the U-shaped structure of bottom end cover stretches in the structure of falling Ψ of worm gear main shaft and forms vertical shaft seal.
Further: described worm gear main shaft top is that the structure of falling Ψ extends upwardly to the position exceeding the highest oil level of worm reduction gear less.
Further: the height that the U-shaped structure of bottom end cover stretches into the structure of falling Ψ of worm gear main shaft equals or exceeds the position of the highest oil level of worm reduction gear.
Further: the worm screw of described worm reduction gear adopts horizontal shaft seal, its bearing locating plate is connected with bearing, be fixed with oil ring nut, worm screw transparent cover internal diameter is socketed on worm screw, external diameter is socketed on worm screw case, be socketed the structure of holding and inwardly forming back leakage groove upward in worm screw transparent cover and oil ring nut, be inwardly connected towards upper protruding block portion and the described oil ring nut endoporus formed that stretches out; Described bearing locating plate has drainback passage, and this drainback passage is communicated with the back leakage groove of worm screw transparent cover, forms drainback passage, is led back in worm screw case by the oil in back leakage groove.
Further: to be provided with coal dust above described supply impeller from powder storehouse, measure below impeller and be provided with lower tube cell, form coal dust and be fed directly to supply impeller by deadweight from push-pull valve from powder storehouse.
Advantage of the present invention is motor and worm reduction gear to above powder impeller, thoroughly solves leakage of oil extruding machine tool and damages that problem---the worm gear of worm reduction gear, worm screw, bearing are always immersed in oil, obtain sufficient lubrication; Supply impeller and the measurement impeller of machine supplying powder are suspended on worm-wheel shaft; Machine supplying powder sealing has 3 roads, before this one maze type, then is three oil sealings and molybdenum disulphide grease, and grease fills up all spaces, can positiver sealing coal dust.In worm reduction gear, oil leaks never, and principle is by centnifugal force and terrestrial attraction, just cannot spill as long as these two power exist oil.

Detailed description of the invention
As shown in Figure 1, 2, 3, worm reduction gear 1 and by worm reduction gear driven rotary supply impeller 2 and measure impeller 3, the worm gear main shaft 4 of described worm reduction gear stretches out downwards, described supply impeller 2 and measure impeller 3 successively with under the worm gear main shaft 4 that stretches out be fixedly connected as the vertical structure be suspended on worm gear main shaft.
As shown in Figure 4, worm gear main shaft 4 top is the structure of falling Ψ, and worm reduction gear bottom end cover 5 is U-shaped structure, and the U-shaped structure of bottom end cover 5 stretches in the structure of falling Ψ of worm gear main shaft 4 and forms vertical shaft seal; Described worm gear main shaft 4 top is that the structure of falling Ψ extends upwardly to the position exceeding the highest oil level of worm reduction gear less, and the height that the U-shaped structure of bottom end cover stretches into the structure of falling Ψ of worm gear main shaft equals or exceeds the position of the highest oil level of worm reduction gear.
Machine supplying powder sealing has 3 roads, can positiver sealing coal dust.In worm reduction gear, oil leaks never, and principle is by centnifugal force and terrestrial attraction, just cannot spill as long as these two power exist oil.
As shown in Figure 5,6, worm screw hermetically-sealed construction of the present invention is: the worm screw 13 of described worm reduction gear adopts horizontal shaft seal, its bearing locating plate 8 is connected with bearing, be fixed with oil ring nut 12, worm screw transparent cover 9 internal diameter is socketed on worm screw 13, external diameter is socketed on worm screw case, be socketed hold the inside structure forming back leakage groove upward at worm screw transparent cover 9 and oil ring nut 12, is inwardly connected towards upper protruding block portion and described oil ring nut 12 endoporus formed that stretches out; Described bearing locating plate 8 has drainback passage, and this drainback passage is communicated with the back leakage groove of worm screw transparent cover 9, forms drainback passage A, is led back in worm screw case by the oil in back leakage groove.During work, oil ring nut and axle rotate simultaneously and oil can be thrown to drainback passage, make oil backflow, can not spill from shaft seal.In figure, 10 is first flat keys, and 11 is belt glue.
The present invention enters powder mode: rotated by driven by motor worm screw, worm and wheel engages, worm gear wheel, supply impeller 2 and measurement impeller 3 are suspended on worm gear main shaft 4 and also and then turn, coal dust directly from inlet point 6 flow into supply impeller by deadweight from push-pull valve from powder storehouse, the supply impeller 2 rotated falls in measurement impeller 3 with coal dust turnback in supply impeller housing to supply impeller housing indentation, there, measurement impeller 3 again turnback takes coal dust to the indentation, there measuring impeller housing, lower tube cell 7 is fallen into by breach, by this circulation, reach the object all sparing to powder He prevent coal dust from flowing automatically.
