The above automatic control production system is essentially also an automatic crushing and mixing system. It transports materials to the crushing mechanism through the conveyor and realizes automatic production in cooperation with the controller, achieving the effects of reducing the operation intensity of workers, improving safety and improving work efficiency.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See alsoFigure 1 , a powder automatic preparation system, including a crushing unit for crushing ingots into powder, a filling unit for quantitatively filling powder, and a dust removal unit. The dust removal unit includes a first dust collector 2 and its first air extraction module, and a second dust collector 10 and its second air extraction module; a dust collection pipeline 101 extends from the first dust collector 2 and multiple dust suction pipelines communicated with the dust collection pipeline 101; the dust suction pipelines are used to extract the escaping dust from the crushing unit and the filling unit; the crushing unit transfers the powder obtained by the crushing unit to the filling unit through a cyclone dust collector 11; the exhaust end of the cyclone dust collector 11 is communicated with the second dust collector 10; a dust return pipeline 115 extending from the second dust collector 10 is communicated with the first dust collector 2.

[0024] The working process of this embodiment can be briefly described as follows: The metal ingot is first put into the crushing unit for multi-stage crushing to obtain powder, and then the powder is transferred from the crushing unit to the filling unit through the cyclone dust collector 11 for quantitative filling, and the powder is filled into an external material bucket for further processing. During the crushing and filling processes, in this embodiment, the first air extraction module continuously provides negative pressure to the first dust collector 2, and at the same time, the dust suction pipelines are arranged according to the places where there is a risk of escaping dust in the crushing unit and the filling unit during actual production, so that the dust suction pipelines can suck the escaping dust and collect it back into the first dust collector 2. In addition, during the transfer process, the second air extraction module continuously provides negative pressure to the second dust collector 10, and the dust return pipeline 115 sucks the too fine dust in the cyclone dust collector 11, and then after passing through the second dust collector 10, it is concentrated into the first dust collector 2.

[0025] Under the above working process, the advantages of this embodiment are that by respectively arranging multiple dust suction pipelines of the dust removal unit corresponding to the crushing unit and the filling unit, and by extracting the too fine dust in the cyclone dust collector 11 through the dust return pipeline 115, the purpose of continuously extracting dust during production is achieved, thereby preventing dust from escaping. Then, the dust extracted by the multiple dust suction pipelines and the dust return pipeline 115 is uniformly transported into the dust removal unit through the dust collection pipeline 101 for collection. The dust collected by the dust removal unit can be recycled, thereby improving production capacity and reducing mechanical loss; in addition, the powder prepared by the crushing unit is transferred into the filling unit through the cyclone dust collector 11, further improving the automation degree of the system.

[0026] It should be noted that in this embodiment, the first dust collector 2 is a bag filter, and the first air extraction module is the first fan 1.

[0027] In this embodiment, specifically, the crushing unit includes a primary crusher 5 for coarsely crushing ingots, a secondary crusher 7 for finely crushing ingots, and a tertiary crusher 8 for finely grinding ingots, which are connected in sequence; the dust suction pipeline includes a first negative pressure pipe 111 for extracting escaping dust from the primary crusher 5, a second negative pressure pipe 112 for extracting escaping dust from the secondary crusher 7, and a third negative pressure pipe 113 for extracting escaping dust from the tertiary crusher 8.

[0031] In this embodiment, the material is transferred between the tertiary crusher 8 and the cyclone dust collector 11 through a pipeline, between the cyclone dust collector 11 and the vibrating screen 12 through a screw conveyor, and between the vibrating screen 12 and the filling machine through a pipeline. The fourth negative pressure pipe 114 is arranged at the feed port of the filling machine to prevent dust from escaping during the powder transfer process.

[0032] More preferably, the dust return pipeline 115 is connected to the dust collection pipeline 101.

[0033] In this embodiment, the exhaust end of the cyclone dust collector 11 is connected to the second dust collector 10; the second dust collector 10 is used to collect fine dust, and the dust return pipeline 115 of the second dust collector 10 is connected to the dust collection pipeline 101. In this embodiment, the dust sucked by the dust return pipeline 115 returns to the dust collection pipeline 101 after passing through the second dust collector 10. The second air extraction module is the second fan 9, and the function of the second fan 9 is to provide a certain negative pressure to collect fine particles.

[0034] It should be noted that in this embodiment, a cyclone dust collector 11 is used to transfer materials. During actual operation, under the centrifugal force of the cyclone dust collector 11, about 90% - 95% of the powder materials are collected. While the powder with too fine particles and too light weight will first be collected by the second dust collector 10. In addition, in order to avoid sucking away normal powder due to excessive negative pressure, an opening regulating valve for keeping the pressure of each unit in a balanced state should be added in practical applications.

[0038] As a further preference of this embodiment, the weighing and filling machine 13 is placed in a closed space and is also provided with an electric door, and the electric door will only open when the externally provided material barrel enters or exits.

[0039] This embodiment also includes a PLC control unit for adjusting the production rhythm, which is mainly completed by multiple level sensors. Under all the above designs, the specific working process of this embodiment is as follows: The first manipulator 3 places the metal ingots in the loading area onto the first conveyor belt 4. After the level sensor on the first conveyor belt 4 detects the material, the ingots are fed into the primary crusher 5 at regular intervals and in fixed quantities for crushing. The large-particle powder obtained is transferred to the secondary crusher 7 by the Z-type feeder 6 for crushing. The small-particle powder obtained falls into the tertiary crusher 8 for crushing to obtain powder. The powder is transferred to the vibrating screen 12 by the cyclone dust collector 11 and screened by the vibrating screen 12. The oversize material falls into the oversize material hopper and waits to be manually poured back into the tertiary crusher 8 for further crushing. The undersize material drops into the weighing and filling machine 13. There is a level sensor in the weighing and filling machine 13, and it performs metering and filling under the control of the PLC control unit. In this embodiment, the temporary conveyor belt 14 of the automatic feeding unit is manually loaded with a bucket. Only when filling is required and filling is completed, the electric door will open to allow the bucket to enter and exit the second conveyor belt 15. After the bucket is released, it first passes through the weighing conveyor belt 16 to measure the actual weight again. If it meets the preset requirements, it is conveyed to the discharging conveyor belt 17 and waits for the second manipulator 18 to complete discharging. If it does not meet the requirements, an alarm is issued to request the intervention of the staff.
