SU57537A1 - Loading device for gas generators - Google Patents

Description

This invention relates to a charging device for gas generators.

A commonly used design with a loading chamber closed with a cone at the bottom gives a constant output of the generating gas to the atmosphere.

This phenomenon is dangerous from a safety point of view and unacceptable for reasons of economic nature.

The proposed device eliminates the possibility of gas escaping through the loading opening and at the same time automates the operation of the mechanism, linking the loading of fuel with its consumption in the gas generator shaft, thereby eliminating the need to monitor the loading.

The construction and operation of the device is explained in the attached drawing, where Figures 1 and 2 show the longitudinal and transverse cuts of the device; in fig. 3 - bucket with a cap; in fig. 4 shows the bucket in the direction of the arrow /) (Fig. 3); in fig. 5-mechanism of the shutter; in fig. 6 - the main details of the latter are shown for clarity when disassembled; in fig. 7-16 consecutive phases of the device.

A vertical partition 27 divides the housing cavity, filled with water to create a shutter, into two parts: the front opening to the atmosphere and the rear connecting to the feedwell 19.

On either side of the partition 27, a difference in the water levels is established, corresponding to an overpressure in the gas generator.

Fuel, such as peat, flows from the bunker 43 to the cylindrical gate 37. The transfer of peat from the gate 37 to the feed neck is carried out by a bucket 22 suspended on two endless chains x 25.

The bucket consists of two parts: the lower (the actual bucket) 22 and the upper 24, which plays the role of an air bell (Fig. 1). The bucket 22 hangs on two pins 49 (fig. 3), freely rotating in the openings of the chain links, and due to the low center of gravity, at all positions of the chain, retains its normal position. The bell 24 freely rotates around the trunnion 49 of the bucket and with the help of counterweights 21 maintains the tilted position.

The bucket loaded with peat, following the movement of chains 25, is immersed in water (Fig. 7). Bell 24 prevents water from entering the bucket. Next, the bucket passes under the partition 27 (Fig. 8), comes out of the water (Fig. 9) and bends around the roller above the loading well 19 (Fig. 10). In this case, the cam 20, fixed to the trunnion of the bucket, meets the stop 9 (Fig. 1) and tilts the bucket (Fig. 11).

Upon further movement, the cam 20 jumps off the support and the empty bucket restores its normal position. During the downward movement of the bucket (Fig. 12), the bell 24 rests against the edge 27 into the partition 27, which gives it an inclined position. Due to this, the bucket is filled with water when immersed.

The passage under the partition, the bell is turned upside down (Fig. 13), the gas released on the surface of the water, which decelerated in its upper part when diving. Then, thanks to counterweights 21, the bell restores the overturned position. When the bucket leaves the water, the cam 20 encounters the stop 30 and tilts the bucket (Fig. 15J. This is necessary in order to drain water from the bucket.

Passing the support 30, the cam and the bucket are rotated to the normal position.

When moving up, the bell hits finger 23 into hook 32 and turns. A further movement of the finger t is not the hook 32, turning the crank 28, which sets in motion the mechanism of the cylindrical shutter.

The shutter 57 is turned downward with a hole, pouring out another portion of peat into the ladle (Fig. 16).

Staying down, the finger of the bell releases the hook 32, crank 28, under the action of a lever with a load, takes its original position, and the bell flips back (Fig. 7). This is followed by a repetition of the cycle.

Chains 25, dead, and the bucket are guided by rollers driven by sprockets 55. Asterisks receive rotation from wheels 34 having a chain drive from intermediate roller 4. Roller 4 rotates with a textrop belt from motor Yu.

When the wheel is rotated 34 tons, the 55 swings the lever 55 with the dog 39 (Fig. 5). The dog rotates the ratchet wheel stuck on the axis 45 of the cylindrical gate 57. Turning the gate causes the lever to lift with a weight of 42. The doggie prevents the backward rotation of the gate).

When the cylindrical gate is turned with the hole up, the ratchet wheel 47 will approach the dog 39 with side a, devoid of teeth, and no further rotation will occur, despite the continued swing of the lever 58.

In this position, the cylindrical gate cavity is filled with peat. When the bucket approaches the loading area (Fig. 16), it turns up the crank 28 and the lever 29 sitting on the same axis. T ha 4S turns the sector 2, which lifts both pawls 39 and /. The shutter under the action of the load 42 turns the hole down and loads the bucket 22.

The volume of the cylindrical cavity of the shutter 57 corresponds to the capacity of the bucket 22.

When lever 29 and sector 2 associated with it take the same position, the ratchet mechanism will turn the valve again.

The shield 40 is rocked on the axis 44 and pressed against the bolt by a load 41. Its purpose is to let the individual large, large pieces slip without pinching when turning the bolt.

When the emptied valve is turned backwards, the shield 40 prevents peat from spilling from the bunker.

In the middle of the casing on the axis 16 fixed wing 13 (Fig. 1, 2). Lever 17 with a load located outside the casing, the wing 13 is pressed against the partition and does not prevent loading. When the lever 29 is rotated, the cable 14, the envelope roller 11 on the switch 12, rotates the lever 17 and with it the wing 18 to the position 15. The switch / 2 lever remains at rest.

If the well 19 is filled with peat so that the wing 13 cannot reach the end position 15, then the cable 14, overcoming the resistance of the lever spring with the roller //, switches off the current. The current is interrupted until the lowering of peat in the well allows the wing 13 to reach the lower position 15.

Then the switch lever, under the action of the spring, returns to the "on" position, and the mechanism will resume operation.

The subject matter of the invention.
