Description

Bucket turnover and flushing assembly of automatic feeding system

technical field

The invention relates to the technical field of uranium purification related equipment, in particular to a barrel overturning and flushing assembly of an automatic feeding system.

Background technique

The uranium chemical concentrate in the process of uranium purification and transformation is a dry powder, block or paste concentrate material containing radioactivity. When the above-mentioned concentrated material is transferred between related processes, it needs to go through a feeding operation. Due to the viscous physical properties of the above-mentioned domestically produced enriched materials and the differences in special barrels, the existing automatic feeding equipment on the market cannot be directly applied to the domestically produced uranium chemical enrichment material feeding operation.

At present, in the industry, three operators are required to work together to achieve the above-mentioned feeding operation. One of them operates a crane to lift the corresponding container (bucket) and move it to the feeding position. Tools such as shovels or rakes remove the concentrated material from the bucket.

The above-mentioned feeding operation has the following shortcomings:

1. Since the weight of the barrel filled with concentrated materials can reach about 1.5t, the physical strength of the operator is relatively high, and the labor intensity of the operator is extremely large;

2. The entire feeding operation requires the tacit cooperation of three operators. The operators are required to have a high degree of proficiency and cooperation. Operation errors by any one party may bring serious consequences, and it is difficult for the operator's own safety to be guaranteed;

3. A component is welded at the bottom of the barrel, and the component is provided with a positioning hole, so that the operator can use a crowbar to force it, which increases the structural complexity of the barrel and increases the manufacturing cost of the barrel;

4. During the feeding operation, the three operators have been in close contact with the radioactive concentrated materials for a long time, which has a great occupational health hazard.

Therefore, it is very necessary to develop an automatic feeding system for uranium purification and enrichment materials. The automatic feeding system should include a barrel overturning and flushing assembly and a feeding and discharging assembly. The barrel overturning and flushing assembly is used to drive the material barrel to turn over to pour out the material, and to flush the inner wall of the material barrel to assist the material discharge.

S05, flip the barrel and the barrel carrier to realize feeding:

The motor 231 is started, and the power of the motor 231 is transmitted to the rotating shaft 222 through the reducer 232 to drive the hanger, the barrel locking mechanism, the barrel and the barrel carrier 33 to turn over synchronously, until the barrel is turned 135° and stops. When the barrel is turned over, the uranium chemically enriched material in the barrel is poured out from the barrel mouth, and enters the next process through the feeding hole 12 on the base 1 .

S06, flush the residual material on the inner wall of the barrel:

First start the water supply from the external water source, so that the high-pressure nozzle 42 sprays water flow; then the operator controls the action of the electric push rod A413 and the electric push rod B414 according to the flushing position of the water flow to adjust the spatial position of the high-pressure spray head 42, so that the high-pressure spray head 42 is aligned with the material barrel The area with residual concentrated material on the inner wall is flushed, and the residual concentrated material flows out of the barrel under the action of water flow, and enters the next process through the feeding hole 12 on the base 1; after the flushing is completed, the piston rod of the electric push rod A413 Retract so that the high pressure spray head 42 is clear of the bucket locking area 25 .

S07, flip the barrel and the barrel carrier back to the horizontal state:

The motor 231 is started, and the power of the motor 231 is transmitted to the rotating shaft 222 through the reducer 232 to drive the hanger, the barrel locking mechanism, the barrel and the barrel carrier 33 to synchronously turn over until the barrel is turned back to a horizontal state and stop; then The scissor-type hydraulic lift 242 is activated, so that the height of the bearing surface 245 is lowered to a level flush with the sliding surface 312. As the height of the bearing surface 245 drops, the upper edge of the bucket is separated from the hook 241, thereby releasing the locked state of the bucket. .

S08, make the mobile trolley A dock the hanger:

The piston rod of the electric push rod C322 stretches out and drives the moving trolley A31 to move along the track 11 until the sliding surface 312 of the moving trolley A31 and the bearing surface 245 of the bucket locking mechanism are flush with each other at the edge and are close to each other. At this time, the moving trolley The A31 is in the docking hanger position.

S09, drag the bucket carrier and bucket back to the mobile trolley A:

a. The piston rod of the hydraulic cylinder 344 stretches out and pushes the carriage 342 to move along the slide rail 341 until the electromagnet 3474 and the two rows of positioning wheels B346 stop moving when they are in contact with the outer wall of the bucket;

b. The electromagnet 3474 is energized and firmly adsorbs the outer wall of the barrel; then the piston rod of the hydraulic cylinder 344 retracts, driving the barrel and the barrel carrier 33 to return from the bearing surface 245 of the barrel locking mechanism to the moving trolley A31 on the sliding surface 312;

c. The electromagnet 3474 is powered off, the adsorption state of the material barrel is released, and then the piston rod of the hydraulic cylinder 344 is further retracted to the initial state;

d. The operator controls the crane to transfer the empty material barrel away, that is, the entire feeding operation is completed;

In the sub-step b of this step, due to the blocking of the bucket blocking portion B333 of the bucket carrier 33, the bucket will not fall from the bucket carrier 33 when it is retracted, but will carry the bucket carrier 33 along with it. go back.
