Description

Automatic bag unpacking machine and bag unpacking system using the bag unpacking machine

technical field

The utility model relates to bag unpacking and unloading equipment for container bags, in particular to an automatic bag unpacking machine and a bag unpacking system using the bag unpacking machine.

Background technique

With the rapid development of the aluminum electrolysis industry, the scale of the aluminum electrolysis plant is gradually becoming super-large, and its production mode is gradually tending to the aluminum electricity joint venture model. As a result, the area where aluminum electrolysis plants are located has gradually extended to remote areas, and the source of alumina has also changed. Most of the previous aluminum electrolysis plants were equipped with corresponding alumina plants, and the supply of alumina was mostly transported by tank trucks and bagged for short-distance transfer. However, with the change of production mode, the transportation of alumina has developed into a long-distance transportation method of ton bags and 1.5 ton bags. For some aluminum electrolysis plants that are not equipped with corresponding alumina plants, their alumina reserves should not be less than 30 days. Taking an aluminum electrolysis plant with an annual output of 700kt/a as an example, the 30-day alumina reserve is 117kt, and the daily consumption is 3.9kt/d, which is 3900 bags/d calculated by ton bag.

From the above examples, we can see that the amount of alumina consumed by aluminum electrolysis plants every day is very considerable. However, in the current alumina supply mode, alumina is stored in warehouses. When used, the stored alumina needs to be transferred to the corresponding place, and then unpacked and unloaded, which is extremely inefficient. Especially in the current production process, manual assisted bag unpacking is used. When unpacking, it is first necessary to use lifting equipment to lift the container bag containing alumina to the corresponding unpacking platform, and then manually use it to unpack the bag. The knife cuts the container bag from the bottom of the container bag, or places the bag breaking tool on the bag unpacking platform. When the crane lowers the container bag, it relies on the self-weight of the container bag to break the bag. The efficiency of the bag method is obviously relatively low. In addition, manual assistance is required during the bag removal process, which also makes it impossible to install a corresponding dust-proof structure at the bag removal platform. The bag removal site is often filled with smoke and dust, which has caused great harm to the health of the staff. On the other hand, the floating alumina powder will inevitably be polluted after settling, which is also not conducive to the recovery and utilization of the floating alumina. Furthermore, since the container bags are directly lifted to the unpacking platform by lifting equipment, the lifting equipment needs to reciprocate continuously, and each unpacking platform needs to be equipped with corresponding lifting equipment. The efficiency is low, and on the other hand, it also puts forward strict requirements on the site and equipment, resulting in a lot of waste of resources.

The bag unpacking system adopts the following technical solutions: the bag unpacking system includes a hanging conveying line and an automatic bag unpacking machine located below the hanging conveying line, the automatic bag unpacking machine includes a dust suppression cover and a dust suppression cover The top of the dust suppression cover has a through-slit for the sling of the conveying line to pass through from front to back, and its front and rear sides are respectively provided with openings for the container bag to pass from front to rear. In addition, the dust suppression cover The lower part of the machine is also equipped with a discharge port; the bag breaking tool is located in the dust suppression cover and is connected with a driving mechanism for breaking bags.

A bag shaking mechanism is also arranged in the dust suppression cover, and the bag shaking mechanism is located at the rear of the bag breaking tool.

The bag breaking tool is a vertically reciprocating bayonet with the tip of the knife facing upwards. The bayonet is assembled on the dust suppression cover through an L-shaped handle. The handle is hinged on the dust suppression cover and forms a seesaw structure. Its outer end forms a The power input end of the transmission connection of the bag breaking drive mechanism. the

Below the conveying line is provided at least one upper bag conveying device.

When using the automatic bag unpacking machine for bag unpacking, the container bag can be lifted by the corresponding lifting equipment. Due to the existence of the top seam and the front and rear side openings of the dust suppression cover, the lifting equipment can directly send the container bag into the In the dust suppression hood, after the container bag is sent into the dust suppression hood, the bag breaking tool is driven by the bag breaking drive mechanism to tear it apart, and the powder material in the container bag automatically falls under the action of gravity and falls from the The discharge port of the dust suppression cover is discharged; from the above description, we can know that when using the automatic bag unpacking machine to unpack the bag, the entire bag unpacking process is carried out in the dust suppression cover, so the diffusion of dust can be effectively controlled.

It can be seen that the automatic bag unpacking machine solves the problem of dust when the powder container bag is broken, reduces the labor intensity of the operator, and improves the efficiency of bag unpacking for the powder container bag.

Furthermore, when there is some residual material in the torn container bag, the bag shaking mechanism located behind the bag breaking tool can further shake the container bag to discharge the residual material; The through-slits and openings mentioned above are not fully enclosed structures, so the negative pressure dust collector is easier to install, and it can actively prevent dust. Compared with the passive dust-blocking seals, the dust-proof effect is obviously much better ;When the reciprocating bayonet is used as the bag breaking tool, the reciprocating bayonet can imitate the action of manually piercing the container bag. The mouth can speed up the discharge of the material in the container bag; the rotary cutter has the advantages of low cost and easy installation.
