Description

Ship-shaped sugarcane ash hanging type pit-dragging elevator and sugarcane ash processing method

Technical Field

The invention relates to a hoist, in particular to a boat-shaped sugarcane ash hanging type pit-dragging hoist and a sugarcane ash processing method.

Background

The bagasse is obtained as a byproduct after the sugarcane is juiced and sugar is made, and can be used as fuel for a biomass power plant. The temperature of the sugarcane dust discharged from the boiler is about 900 ℃. Due to the high temperature, cooling is required before being conveyed out by the conveyor. Because the volume of the sugarcane ash is relatively large and the specific gravity of the sugarcane ash is too light (the specific gravity of the sugarcane ash is 0.2-0.3t/m 3), the existing cooling mode generally adopts water seal cooling.

In the prior art, the method for treating the sugarcane dust comprises the following steps:

firstly, adopting water to flush. The cooled cane ash is conveyed to a cane ash pool for storage through a special ditch, and is deposited and buried. However, this treatment method does not meet the environmental protection requirement and has been prohibited.

Secondly, the gumbo sugar refinery adopts a belt conveyor to convey the cane ash, but the cane ash is suspended in water, does not move along with the belt and a driving roller slips, so the gumbo cannot be normally used and only needs to be dismantled.

At present, the national mechanical industry standard vertical bucket elevator (JB/T3926-. The cane ash soaked in the cooling water is bonded into a mass, does not belong to loose materials and is excluded. On page 505 of the national design manual, "handbook for selection of transportation machinery", there are descriptions of the application range and classification of bucket elevators. The cane ash after being soaked in the cooling water is bonded into a ball and is removed. A national design manual, transportation machinery selection design manual, page 605 and 606, introduces a dewatering and pit-dragging bucket elevator. It is mainly used in coal preparation plant and calcium magnesium phosphate fertilizer plant. The cane ash soaked in the cooling water is bonded into a ball, so that the channel is easy to block, and the water and ash can not be separated and can be discharged.

The reason why the bucket elevator is excluded is that the bucket elevator is sensitive to overload, the hopper and the traction member are easily damaged, and water-ash separation is impossible.

At present, no precedent for conveying the sugarcane dust by adopting other types of conveyors (such as a belt conveyor, an embedded scraper conveyor and the like) is provided in China.

As shown in fig. 2-5, the head includes a head casing 1.4, a head discharge opening 1.3 is opened at the lower end of the head casing 1.4, a head shaft 1.5 is installed in the head casing 1.4, a pair of head wheels 1.6 are fixed on the head shaft 1.5, and a conveying chain 5.1 in the bucket chain group 5 is engaged with the head wheels 1.6 and moves along with the rotation of the head wheels 1.6.

As shown in fig. 2 and 5, a discharging mechanism 1.7 is installed in the head housing 1.4 near the head shaft 1.5, and the discharging mechanism 1.7 comprises a head bearing assembly 1.7.1, a seal seat 1.7.2, a discharging wheel 1.7.3, a discharging shaft 1.7.4, a flat key 1.7.5, a head coupling 1.7.6 and a head bearing seat support 1.7.7.

Wherein the discharge wheels 1.7.3 are used in pairs and arranged at two sides at intervals. The discharge wheel 1.7.3 is fixed on the discharge shaft 1.7.4 by a flat key 1.7.5. The upper two ends of the discharging shaft 1.7.4 are assembled with the head bearing assembly 1.7.1 and are arranged on the head shell 1.4.

The sealing seat 1.7.2 is fastened to the head housing 1.4 by a head coupling 1.7.6 for sealing the gap at which the discharge shaft 1.7.4 projects out of the head housing 1.4.

The head bearing mount support 1.7.7 is welded to the head housing 1.4, which is the carrier of the head bearing assembly 1.7.1. The bearing in the head bearing assembly component 1.7.1 is a ball bearing, and has an automatic aligning function on one hand and can bear larger bending moment and torque on the other hand.

When the sugarcane dust is obliquely conveyed from left to right, the head wheel 1.6 can only rotate anticlockwise, and the head wheel 1.6 drives the bucket chain group 5 to move. Under the action of the bucket chain group 5, the discharging wheel 1.7.3 rotates anticlockwise.

When the sugarcane dust is obliquely conveyed from right to left, the head wheel 1.6 can only rotate clockwise, and the head wheel 1.6 drives the bucket chain group 5 to move. Under the action of the bucket chain group 5, the discharging wheel 1.7.3 rotates clockwise.

For the conventional vertical bucket elevator (JB/T3926-. The specific contents are as follows:

firstly, the hoister lifts materials from right to left in an inclined manner. The head pulley of the conventional elevator can only rotate in the counterclockwise direction. (i.e. the material lifting hopper is always at the upper end, the empty hopper is always at the lower end, and cannot be changed)

For the purposes of this application, the elevator head pulley is designed to rotate in a clockwise direction, as opposed to conventional. (i.e. the material-lifting hopper is at the lower end and the empty hopper is at the upper end)

And secondly, when the hoister inclines to lift the materials from left to right. The head pulley of the conventional elevator can only rotate clockwise. (i.e. the material lifting hopper is always at the upper end, the empty hopper is always at the lower end, and cannot be changed)

For the purposes of this application, the elevator head pulley is designed to rotate in a counterclockwise direction, as opposed to conventional. (i.e. the material-lifting hopper is at the lower end and the empty hopper is at the upper end)

That is, the lifting machine of the application can not only lift upwards, but also transport downwards.

As shown in fig. 2 and 5, the discharging wheel 1.7.3 is a smooth wheel without tooth shape, and is of a single-side flange structure, and the professional common language is called 'F' type for short. The rollers 5.2 on the bucket chain group 5 are assembled discontinuously, when the rollers 5.2 pass through the discharging wheel 1.7.3, a strong polygonal effect can be generated, and at the moment, the sugarcane dust adhered to the bucket chain group 5 can automatically fall down from the head discharging opening 1.3 for discharging, so that the phenomenon of material return is effectively avoided.

As shown in fig. 2, the head of the lifter is obliquely arranged, the discharging shaft 1.7.4 and the head shaft 4 are horizontally arranged, and the uppermost ends of the discharging wheel 1.7.3 and the head wheel 1.6 are consistent. The elevator is an inclined lifting conveying, so the head is arranged in an inclined way. If the whole head is horizontally arranged, an upper bending section is required to be added, and the structure is complicated. Thus, in general, the head is arranged obliquely.

The discharge shaft 1.7.4 and the head shaft 1.5 can also be arranged obliquely, but the forced discharge function is much less. When the discharging shaft 1.7.4 and the head shaft 1.5 are horizontally arranged, cane ash adhered to the two surfaces (cane ash adhered to the front surface and the rear surface of the bucket type scraper) can be removed to the maximum extent.

As shown in fig. 6 to 7, the casing 2 of the lifting section comprises a casing body 2.1, and the casing body 2.1 is composed of a first cover plate 2.4, a first side plate 2.5, and a first bottom plate 2.6.

A first return guide rail 2.9 is welded to the first guide rail support 2.8. The bearing section of the conveyor chain 5.1 is arranged on the first bearing guide rail 2.7, the no-load section of the conveyor chain 5.1 is arranged on the first return guide rail 2.9, and the scraper hopper 5.3 of the bearing section of the conveyor chain 5.1 is arranged in the first concave groove 2.2. A gap 2.3 is formed between the two ends of the scraper type hopper 5.3 and the first concave groove 2.2, and a drawer type hopper is formed between the scraper type hopper 5.3 and the first concave groove 2.2. In the process of lifting the conveying chain 5.1 upwards, the drawer-type hopper drives cane ash to lift and carry out water-ash separation.

As shown in fig. 21-22, one end of the curved section housing 3 is horizontal for connection with the horizontal flooded section housing 4.

In addition, a water inlet 3.10 is arranged at the upper end of the bending section shell 3, and a water outlet 3.7 is arranged at the bottom of the bending section shell 3. When the cooling water exceeds the warning water level, the cooling water automatically overflows from a water outlet 3.7; when the cooling water is lower than the warning water level, water is automatically supplemented from the water inlet 3.10.

As shown in fig. 8 to 9, the horizontal soaking section housing 4 includes a horizontally disposed soaking housing body 4.1, and the soaking housing body 4.1 is composed of a second cover plate 4.1.1, a second side plate 4.1.2, and a second bottom plate 4.1.3. The second side plate 4.1.2 is one piece left and right, and the second cover plate 4.1.1 and the second side plate 4.1.2 are assembled together through a connecting piece 4.1.4. The second bottom plate 4.1.3 and the second side plate 4.1.2 are assembled into a whole by adopting a continuous fillet welding stage.

The top end of the water immersion shell body 4.1 is connected with the bottom of the cane ash groove 11 and is used for receiving burnt cane ash 8 with high temperature. The soaking shell body 4.1 is filled with cooling water 9, and the cooling water 9 is used for cooling and precipitating the sugarcane dust with higher temperature. Before the hoisting type pit-dragging hoister leaves a factory, the water seepage test must be carried out on the water-immersed shell body 4.1, so that water leakage is avoided.

Wherein the second carrier rail 4.4 is fixed to the second base plate 4.1.3 by means of plug welding and interrupted fillet welding. The second return guide rail 4.5 is fixed to the guide rail support 4.7 of the second side plate 4.1.2 by means of plug welding and interrupted fillet welding.

When the conveyor chain is in work, the bearing section of the conveyor chain 5.1 is arranged on the second bearing guide rail 4.4, the no-load section of the conveyor chain 5.1 is arranged on the second return guide rail 4.5, and the scraper type hopper of the conveyor chain 5.1 positioned on the bearing section is arranged in the second concave groove 4.3. Gaps (used for water passing) are formed between the two ends of the scraper-type hopper and the second concave groove 4.3, and in the process that the conveying chain is conveyed forwards, the scraper-type hopper 5.3 and the second concave groove 4.3 form a drawer-type hopper and convey sugarcane dust forwards horizontally.

As shown in fig. 9, the second cover plate 4.1.1 on the upper portion of the immersion shell body 4.1 is provided with two sets of sedimentation mechanisms 4.6, each set of sedimentation mechanism 4.6 includes a sedimentation rotating shaft 4.6.1, and the two sets of sedimentation rotating shafts 4.6.1 extend out of the immersion shell body 4.1 and are driven to rotate by a sedimentation driving mechanism 4.6.2.

As shown in fig. 10, the sedimentation driving mechanism 4.6.2 includes a gear transmission mechanism 4.6.4 and a sedimentation motor 4.6.5, wherein the gear transmission mechanism 4.6.4 includes a first gear and a second gear respectively fixed on the two sedimentation rotation shafts 4.6.1, a third gear and a fourth gear mounted on the second cover plate 4.1.1, and the first gear, the second gear, the third gear and the fourth gear have the same size and are meshed in sequence. Wherein the third gear is driven to rotate by a settlement motor 4.6.5.

As shown in fig. 9 and 11, since the four gears are sequentially engaged, the four gears all rotate and the first and second gears are turned in opposite directions, so that the two sinking rotation shafts 4.6.1 are also turned in opposite directions and all rotate inward. A plurality of pressing plates 4.6.3 are circumferentially arranged on the settling rotating shafts 4.6.1, and the pressing plates 4.6.3 on the two settling rotating shafts 4.6.1 are close to each other. In the process of rotating the sedimentation rotating shaft 4.6.1, the pressing plate 4.6.3 presses the cane ash into the water, the cane ash absorbs water in the water to form a cluster, and the cane ash slowly sediments under the water surface and falls into the second concave groove 4.3.

Since roller 5.2 is of a one-sided flange type construction, the diameter of roller 5.2 is much greater than the height of the swaged link body. Thus, the movement of the conveyor chain within the hoist housing, whether it be the return or the load-bearing section, is rolling friction.

The conveying chains 5.1 are used in pairs, so that the automatic positioning function is realized after assembly; the automatic centering function is also realized during operation.
