[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] A quantitative collection mechanism for copper and gold powder, such as Figure 1-5 As shown, it includes a supporting body, a vibrating screen 1, a feeding system 2, a gravity detection system 3 and a controller 10. The top surface of the supporting body is equipped with a vibrating screen 1, the vibrating screen 1 is connected to a collecting box 9 through the feeding system 2, and the gravity detection system 3 is abutted below the collecting box 9. The vibrating screen 1 is connected to a large particle collecting box 8 through a discharging pipeline. A vacuum heating device and a controller 10 are provided on the supporting body. The controller 10 is communicatively connected with the vibrating screen 1, the gravity detection system 3 and the vacuum heating device. The large particle collecting box 8 is installed on one side of the supporting body, and the controller 10 is installed on the other side of the supporting body. A support platform and a support plate are provided on the supporting body. The large particle collecting box 8 is installed on the support platform, and the gravity detection system 3 is installed on the support plate. The vibrating screen 1 is designed to effectively separate large particles and automatically discharge them into the large particle collection box 8, while the fine particles continue to flow through the feeding system 2, effectively reducing the manual cleaning of large copper and gold powders accumulated after screening by workers, and improving the collection efficiency. When the copper and gold powders in the collection box 9 are collected to the value set by the gravity detection system 3, the controller 10 controls the first electric valve 4 and the second electric valve 5 to close, the vibrating screen 1 stops cutting off the feeding and loading, and the quantitative collection is completed. The first electric valve 4 and the second electric valve 5 are closed to form a closed space, and the vacuum heating device is used to prevent the copper and gold powders from contacting with the outside air to cause moisture, oxidation or pollution, etc., which will affect the quality of the raw materials.

[0032] The feeding system includes a feed ramp 21, a feed box 22 and a baffle 23. The feed ramp 21 is connected to the feed box 22 through a slideway. Baffles 23 are installed on both sides of the feed ramp 21. The feed ramp 21 and the baffle 23 are both installed in the support body. The feed box 22 is installed on the outer side of the support body. A slideway is opened on the support body between the feed ramp 21 and the feed box 22. The baffles 23 on both sides of the feed ramp 21 are arranged in an eight-shaped shape, and the smallest hole of the eight-shaped shape faces the slideway to ensure that the screened copper and gold powder accurately passes through the slideway after the feed ramp 21 slides downward. , arrives at the feed box 22, preventing the screened copper-gold powder from being blocked by the supporting body between the feed box 22 and the feed inclined plate 21 and causing accumulation. Most of the other side of the eight-shaped baffle 23 is connected to the supporting body, and a certain gap is left at the highest point to facilitate the operation of the vacuum heating device. The simple design is convenient for replacement and maintenance. An inverted cone-shaped hole is provided in the feed box 22 to facilitate the discharge of the copper-gold powder through the slide, and the feeding is further accelerated by the vibration transmission of the vibrating screen. The interior of the feed box 22 is an inverted cone-shaped hole, and there are landslides all around, so that the copper-gold powder falls smoothly to the collection box 9.

[0033] The vibrating screen 1 is connected to the feed inclined plate 21 through the first electric valve 4, and the feed box 22 is connected to the collection box 9 through the second electric valve 5. The gravity detection system 3 includes a pressure plate 31 and a pressure sensor 32. The pressure sensor 32 is installed under the pressure plate 31. The pressure sensor 32 communicates with the first electric valve 4 and the second electric valve 5. The opening and closing of the first electric valve 4 and the second electric valve 5 are controlled by the gravity detection system 3. The gravity detection system 3 is adjusted by the controller 10 to complete the precise control of material collection in the collection box 9. Through automatic control and real-time feedback, the workload of the operator is effectively reduced and the possibility of human error is reduced. The second electric valve 5 is installed at the outlet of the feed box 22, and the outlet of the feed box 22 is assembled with the inlet of the collection box 9.

[0034] The vacuum heating device includes a vacuum pump 6 and a plurality of heaters 7. The vacuum pump 6 is installed on one side of the support body. The vacuum pump 6 is connected to the support body through a ventilation pipe. The plurality of heaters 7 are installed in the support body. The plurality of heaters 7 are installed on the side wall of the support body below the feed ramp 21. The feed box 22 is installed on the side away from the vacuum pump 6. The support body is divided into two parts by the feed ramp 21 and the inclined baffle 23. The baffle 23 is the feed part, and the other part is the vacuum heating part. The eight-shaped baffle 23 can not only ensure the accurate passage of the copper and gold powder, but also prevent the remaining copper and gold powder inside from flying out of the feed part when the vacuum pump 6 sucks out the air after the feeding is stopped. The vacuum pump 6 can keep the internal space in a vacuum state to avoid the reaction between the raw material and the oxygen in the air, and keep the internal space at a suitable dry temperature through the heater 7 to avoid the influence of the infiltration of humid air from the outer wall, and effectively prevent the internal device from rusting, increase the service life of the device, and achieve a better preservation effect on the copper and gold powder in the support body, so as to prepare for the next quantitative collection.

[0035] Working principle: first, the threshold of the gravity detection system 3 is set through the controller 10, the top cover of the vibrating screen 1 is opened, and the copper and gold powder after production is connected. At the same time, the vibrating screen 1 is vibrated for screening through the controller 10. The copper and gold powder with large particles that cannot pass through the screen layer flows out through the discharge pipeline provided on the side of the vibrating screen 1 with the vibration and enters the large particle collection box 8. At the same time, the copper and gold powder that passes through the screen layer falls onto the feed inclined plate 21 through the first electric valve 4. The kinetic energy transmitted by the gravity and the vibrating screen 1 makes it slide on the feed inclined plate 21 and finally arrives at the feed box 22, and further enters the collection box 9 through the second electric valve 5. When the copper and gold powder in the collection box 9 reaches the set threshold, the gravity detection system 3 triggers the closing of the first electric valve 4 and the second electric valve 5 to complete a quantitative collection.

[0036] When the next quantitative collection has not started, the controller 10 starts the vacuum heating device inside to purify the internal space to prevent the quality of the copper-gold powder inside from changing.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
