The liquid outlet unit is essentially a liquid outlet pipe with a flow valve, and the liquid outlet amount per unit time can be controlled through the flow valve. The slurry opening pool 200 is used for performing slurry opening and emulsification on loose powder discharged from the lining bag, correspondingly, the slurry opening pool 200 is connected with a conveying device 500, the conveying device 500 can be a pumping machine, a feeding pipe of the conveying device 500 extends to the bottom of the slurry opening pool 200, a discharging pipe of the conveying device extends to a production area of a downstream customer, and the conveying direction of the conveying device 500 is arranged from the slurry opening pool 200 to the production area.

It should be noted that the discharge connecting device 300 is a prior application of my own, and the specific structure thereof can refer to "auxiliary discharge device" with publication number CN216037450U, and the invention will not be described in detail in the specific structure thereof.

In other embodiments, the specific structure of the discharge connection device 300 can be further referred to other prior applications in my own, such as "a discharge connection device" with publication number CN209507122U or "a connection device for loose powder discharge" with publication number CN212126832U, without being limited to the above-mentioned embodiments.

In some embodiments of the present invention, in order to facilitate settlement between two parties of trade, the system for bulk powder transportation and feeding in containers further comprises a weighing device 800, wherein the weighing device 800 is configured at the discharge area of the downstream customer, specifically, the wagon balance. Before and after the container 100 is unloaded, the container needs to be weighed by the weighing device 800, the difference value between the two is the transaction amount of the loose powder, and the transaction amount multiplied by the unit price of the loose powder is the transaction amount. If the semitrailer is used for unloading, before unloading, the semitrailer needs to run to the weighing device 800 for weighing, the weight of the semitrailer comprises the weight of the semitrailer, the weight of the container 100 and the weight of scattered powder, after unloading, the semitrailer needs to run to the weighing device 800 for weighing again, the weight of the semitrailer comprises the weight of the semitrailer, the weight of the container 100 and the weight of residual scattered powder, and the weight of the scattered powder unloaded into the slurry tank 200 can be obtained by subtracting the front weight and the rear weight. If the plate turnover device 700 is used for discharging, before discharging, the crane 600 transfers the container 100 to the weighing device 800 for weighing, after discharging, the crane 600 transfers the container 100 to the weighing device 800 again for weighing, and the weight of the loose powder discharged into the pulping tank 200 can be obtained by subtracting the front weight and the rear weight.

Further, in order to simplify the weighing process, the weighing device 800 is located on the moving path of the plate turnover device 700, so that the weighing device 800 can weigh the container seamlessly when the moving unit 730 drives the container 100 to feed or retract. If the roller 731 of the moving unit 730 is a grooved roller, the upper surface of the weighing device 800 is also provided with a track matching with the grooved roller to ensure the continuity of the moving unit 730 during moving.

Before discharging, a proper amount of solution is reserved in the slurry opening tank 200 through the slurry outlet unit so as to facilitate primary stirring; during the discharging process, the stirrer 400 is continuously operated, and the liquid outlet unit is continuously or intermittently operated to continuously perform the slurry emulsification on the loose powder. When the water content of the emulsion is reduced, the viscosity of the emulsion is increased, and the stirrer 400 is easy to break down, in order to adjust the viscosity of the emulsion, the liquid outlet unit needs to inject liquid into the slurry tank 200 in equal proportion according to the current discharging amount of the scattered powder, because the total liquid outlet amount of the liquid outlet unit and the total discharging time of each box of the scattered powder are positively correlated with the total weight of the scattered powder, and the total weight of each box of the scattered powder can be calculated by the weighing device 800, the liquid outlet amount of the liquid outlet unit per unit time can be determined by dividing the total liquid outlet amount by the total discharging time. It is understood that, if the loose powder is starch, the solution for slurrying the loose powder is water, and if the loose powder is other powder, the solution for slurrying the loose powder is selected according to the characteristics of different powder, and is not limited to water.

In some embodiments of the present invention, since the internal air pressure of the slurry tank 200 is in a positive pressure state during the discharging of the bulk powder, in order to balance the internal air pressure of the slurry tank 200, the sealing cover 210 is further provided with an air port 212, and the air port 212 is connected with a dust removing device 900. The dust removal device 900 can be a bag-type dust remover, the bag-type dust remover is provided with a recovery bin, the recovery bin is communicated with a fan, an air guide pipe of the fan is hermetically connected with the air port 212 of the sealing cover 210, and the fan provides negative pressure for the air guide pipe, so that air in the pulp opening pool 200 can enter the recovery bin through the air guide pipe. The recycling bin is provided with an exhaust pipe, the bottom of the recycling bin is in an inverted cone shape, the lower end of the recycling bin is provided with a recycling port, the recycling port is connected with an air seal, and the outlet of the air seal is connected with a powder collecting bag. When the gas mixed with the scattered powder enters the recovery bin, the scattered powder is deposited at the bottom of the recovery bin because the density of the scattered powder is greater than that of air, and redundant gas is discharged from the exhaust pipe; when the airlock starts, the powder positioned at the bottom of the recovery bin can be conveyed into the powder collecting bag, so that a user can conveniently collect the recovered loose powder. The dust removing device 900 not only provides negative pressure to balance the internal air pressure of the pulping tank 200, but also purifies the air passing through the dust removing device 900 to adsorb the scattered powder dispersed in the air, thereby preventing the scattered powder from being discharged into the atmosphere. It should be understood that the invention is not limited to the specific structure of the dust collector 900, as long as the dust collector 900 can absorb the air in the pulping tank 200, and whatever the structure of the dust collector 900 is, the invention is within the protection scope of the invention.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
