Feeding system and refining system

Technical Field

The present disclosure relates to the field of mineral refining, and more particularly to a feed system and refining system.

Background

The basic process flow in the existing production field such as smelting (or refining) for mineral products is batching, mixing and smelting. In smelting production, high temperature is often accompanied, raw materials are often required to be mixed in proportion in the process of proportioning, the health of workers is not benefited under the condition of high-concentration dust, and in addition, dust in the smelting raw materials often contains a large amount of sulfur, so that the environment is seriously polluted, and the equipment structure and the building are corroded after meeting water. At present, in the smelting process, the mode of manually feeding the raw materials in the whole series of processes of proportioning, transporting and charging into a furnace has low labor efficiency and more potential safety hazards. With the shortage of manpower resources and the rise of manpower cost and the severe working environment, fewer people are engaged in the industry. Thus, there is a need to develop reduced labor feed systems and refining systems to address production tasks.

The Chinese patent application CN114438333A published in 2022, 5 and 6 discloses a method for producing regenerated lead by smelting without iron, which adopts the processes of batching, mixing and smelting. Wherein, the mixture obtained in the mixing step is sent to a charging box at the top of the smelting furnace through a belt conveyor, and then is conveyed into the smelting furnace through a screw feeder at the lower part of the charging box.

For mineral smelting, if a belt conveying mode is adopted between mixing and smelting, a one-to-one relationship between belt conveying and smelting furnaces is caused, and for the condition that a plurality of smelting processes are carried out simultaneously, belt conveying between each smelting furnace and equipment of a mixing process is required to be established, in other words, a plurality of sets of belts are required to carry out conveying and screw feeding, which leads to the increase of the cost of the whole equipment of a smelting system.

In addition, by adopting the belt conveying mode, the mixture is paved on a belt for conveying, so that the quantitative supply of the mixture to the smelting furnace is difficult to accurately control.

Further, by erecting the track beams 51, the space in the height direction is fully utilized, which also makes full/maximum use of the valuable floor space of the factory building, and is also beneficial to cost control in terms of land use in enterprise production.

In contrast to the prior art belt conveyor approach, in the feed system 100 of the present disclosure, the grasping of the material is quantitatively refined by employing the grapples 54 of the traveling crane 5, so that the quantitative feed mix for the corresponding refining furnace 200 can be precisely controlled.

In addition, by the cooperation of the storage bin 4 and the traveling crane 5, the operations of the discharging unit 2, the proportioning bin 3 and the proportioning bin 1 can be changed to the operations not strongly related to the supplied refined materials of the plurality of refining furnaces 200 (i.e. the operations are separated from the necessary serial operations) due to the arrangement of the storage bin 4, so that the operations of the discharging unit 2, the proportioning bin 3 and the proportioning bin 1 and the operations between the traveling crane 5 and the plurality of refining furnaces 200 become more flexible.

In addition, compared with the belt conveying mode of the background art, in the feeding system 100 of the present disclosure, through the cooperation of the storage bin 4 and the grab bucket 54 of the crane 5, under the condition of the same weight of refined materials, the exposed surface of the refined materials is greatly reduced, which greatly reduces dust caused by the conveying of the refined materials in the factory building, and further greatly reduces the pollution of sulfur contained in the raw materials of mineral products to the environment of the factory building and the corrosion to the constituent equipment of the feeding system 100 and the wall of the factory building, improves the quality of the working environment, and prolongs the service life of the constituent equipment of the feeding system 100.

In the feeding system 100 of the present disclosure, the mixing can be regularly and quantitatively and uniformly and accurately carried out through the cooperation of the mixing bin 1, the discharging unit 2 and the mixing bin 3, so that the labor cost is greatly reduced, the time and the labor amount of manual metering and manual material conveying are reduced, the danger of manual operation is reduced, and the production efficiency is improved.

Referring to fig. 2, in one example, the feed system 100 further includes a PLC system 6. Accordingly, the discharging unit 2 is communicatively connected to the PLC system 6 to quantitatively discharge the raw materials transported to the discharging position of the adjacent blending bin 1 into the blending bin 1, the blending bin 3 is communicatively connected to the PLC system 6 to dispense the ingredients into the blending bin 1 such that the raw materials and the ingredients in the blending bin 1 form the blended materials in a prescribed weight ratio, the slide table 52 is communicatively connected to the PLC system 6 to be able to control the lifting of the slings 53 and the reciprocating movement of the slide table 52 along the track beam 51 between the upper side of the storage bin 4 and the refining furnace 200 (including uniform translation and deceleration movement when grabbing and releasing the refined materials for the grab bucket 54), the grab bucket 54 is communicatively connected to the PLC system 6 to be able to be opened to grab the refined materials from the storage bin 4 based on the amount of the refined materials required by the refining furnace 200, to be able to be closed to complete grabbing the refined materials, to be able to control the opening and closing degree to leak the grabbed refined materials to the storage bin 4 and to be able to be opened to supply the refined materials to the refining furnace 200.

The material transported to the discharge location may take a variety of forms. To fully utilize the planar floor space of the plant and to increase the flexibility of transporting the raw materials to the discharge location, in one example, as shown in fig. 1 and 2, the raw materials transported to the discharge location are provided by a raw materials wagon 300. The discharge unit 2 includes a wagon balance 21 and a discharger 22. The wagon balance 21 is used for weighing the raw material wagon 300 to obtain the total weight of the raw material loaded by the raw material wagon 300 of the weight where the raw material is discharged during the discharging process. The unloader 22 is supported on the wagon balance 21, and the unloader 22 is used for lifting and tilting the raw material wagon 300 so that the raw material loaded by the raw material wagon 300 is gradually poured into the mixing bin 1 during a discharging time.

In actual operation, after the raw material truck 300 is located on the unloader 22, a corresponding wheel locking device (not shown) may be used to lock the wheels of the raw material truck 300 on the unloader 22 (in addition, a stopper (not shown) may be configured on the unloader 22 to limit the rear end of the inclined raw material truck 300 at a lower position so as to avoid the raw material truck 300 from sliding down), when the unloader 22 is used to lift and incline the raw material truck 300 in place, the tail plate of the raw material truck 300 is opened to perform unloading, and the inclination angle of the raw material truck 300 is used to control the unloading speed of the raw material in the raw material truck 300 (i.e. the raw material loaded by the raw material truck 300 is gradually poured into the mixing bunker 1 in an unloading time), the unloading speed of the raw material can be obtained by the weight of the wagon 300 when the wagon 21 is not unloaded, the weight of the raw material is reduced in real time, and the weight of the wagon 300 can be obtained by the weight of the wagon 300 when the wagon 21 is completely unloaded, and the total weight of the raw material loaded by the wagon 300 is obtained.

When the feeding system 100 further comprises a PLC system 6, the unloader 22 is in communication with the PLC system 6, and accordingly, the proportioning bins 3 in communication with the PLC system 6 dose the corresponding ingredients into the proportioning bins 1 at the corresponding rate according to the amount of the ingredients fed into the proportioning bins 1 determined by the unloading time of the raw materials of the unloader 22 according to the prescribed weight ratio.

The support plate 223 is located on the wagon balance 21.

As shown in fig. 1, in one example, the proportioning bin 3 is provided with a load cell 31 and an adjustable blanking valve 32. The load cell 31 is used for monitoring the weight of the proportioning bin 3 in real time. The load cell 31 is in communication with an adjustable blanking valve 32 to effect dosing of the ingredients in the ingredient bin 3 at a corresponding rate by controlling the opening of the adjustable blanking valve 32. Likewise, when the feed system 100 further comprises a PLC system 6, the load cell 31 is in communication with the regulated feed valve 32 and the PLC system 6 to effect dosing of the ingredients in the ingredient bin 3 at a corresponding rate by controlling the opening of the regulated feed valve 32.

When the storage bin 4 needs to be replaced with refined materials, the inclined position 42 is arranged to be beneficial to the dumping of the storage bin 4, and when the refined materials in the storage bin 4 are reduced to a certain amount so that the inclined position 42 is exposed or reduced to a certain height of the inclined position 42, besides the real-time monitoring of the weight sensor 41, the exposed inclined position 42 is also beneficial to the manual auxiliary monitoring of the amount of the refined materials in the storage bin 4.

In order to control the dust generated by the refinery feedstock in the storage bin 4, the top of the storage bin 4 may be provided with a movable cover 43, the movable cover 43 being used to open and close the top of the storage bin 4. The movable cover 43 is preferably in an automatic manner, as such the movable cover 43 is in communication with the PLC system to effect the cooperation of the movable cover 43 with the operation of the mixing silo 1 and the grapple 54 of the crane 5.
