Description

Technical Field

[0001] This application belongs to the technical field of auxiliary equipment for mineral processing plants, and more specifically, it relates to an automatic shift-based turntable for sorting and receiving product output and samples in mineral processing plants. Background Technology

[0002] In the production management of mineral processing plants, in order to accurately evaluate the operational quality and production efficiency of each shift, it is necessary to conduct statistical analysis on the product output and product quality (through sample testing) of different shifts. Currently, the industry generally adopts a manual method for receiving products and samples by shift. That is, a dedicated person is assigned to use 3 or 4 receiving buckets to correspond to 3 or 4 shifts, manually switching the receiving buckets to collect products from different shifts. Then, in the morning shift, the products in each bucket are weighed to count the output, and the samples in each bucket are sent to the laboratory for quality testing.

[0003] However, this manual shift-based receiving method has many drawbacks: on the one hand, it requires additional dedicated personnel to be responsible for the switching and management of the receiving bins, which increases the labor force of the concentrator and raises labor costs; on the other hand, manual operation makes it difficult to accurately control the timing of the receiving bin switching, which can easily lead to the mixing of products from different shifts, resulting in shift errors and affecting the accuracy of production statistics and sample testing results; at the same time, the manual operation process is cumbersome and inefficient, making it difficult to meet the needs of continuous and efficient production in the concentrator. Utility Model Content

[0004] To address the technical problems of high labor requirements, low production efficiency, and easy shift errors in the existing technology of manually receiving products and samples from mineral processing plants in shifts, this paper provides an automatic shift-based turntable for receiving product output and samples from mineral processing plants. This enables automatic and accurate receiving of product output and samples from different shifts, reducing labor costs and improving production efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: An automatic shift-based receiving turntable for product output and samples in a mineral processing plant is provided, comprising: a turntable base, a tray, receiving buckets, a drive mechanism, and an electrical control mechanism. The turntable base is installed on a device foundation. The tray is rotatably mounted on the turntable base. Three or four receiving buckets are arranged at equal arc intervals around the center of the tray. The drive mechanism is connected to the tray and drives the tray to rotate. When the tray rotates, the electrical control mechanism controls the corresponding receiving bucket to be positioned directly below the material feed pipe.

[0006] In one embodiment, the tray is rotatably mounted on the turntable base via a planar bearing and a central bearing.

[0007] In one embodiment, the turntable base is mounted on the device base via four adjustable feet.

[0008] In one embodiment, the drive mechanism includes: a motor reducer, a drive pinion, and a reduction gear. The drive pinion is fixedly mounted on the output shaft of the motor reducer, and the reduction gear is fixed on the circumferential surface of the tray. The drive pinion and the reduction gear mesh.

[0009] In one embodiment, the electrical control mechanism includes a PLC control box, metal induction plates, and position sensors; three or four metal induction plates are provided and fixed on the tray corresponding to the positions of each receiving bucket, and the position sensors are fixed on the outside of the tray and electrically connected to the PLC control box.

[0010] In one embodiment, the tray is provided with a limiting ring to limit the position of the receiving bucket.

[0011] In one embodiment, the turntable base is provided with a water collection tank, the tray is provided with a water flow hole communicating with the water collection tank, and a drain pipe is installed at the bottom of the water collection tank.

[0012] In one embodiment, the receiving bucket is a stainless steel bucket.

[0013] The beneficial effects of the automatic shift-based receiving turntable for mineral processing plant product output and samples provided in this application are as follows: According to the shift situation, three or four receiving buckets are placed on the tray. The tray is automatically rotated by the cooperation of the electrical control mechanism and the drive mechanism, so that the corresponding receiving bucket is located directly below the material feed pipe to receive the material of the corresponding shift. This achieves automatic and accurate receiving of product output and samples of different shifts, reduces labor costs, and improves production efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] like Figure 1As shown in the illustration, an automatic shift-sorting turntable for product output and sample collection in a mineral processing plant, provided in this application embodiment, will now be described. This automatic shift-sorting turntable for product output and sample collection in a mineral processing plant is mounted on a foundation 1 and located below the material feed pipe 17. Specifically, the automatic shift-sorting turntable for product output and sample collection in a mineral processing plant includes: a turntable base 3, a tray 6, a collection bucket 7, a drive mechanism, and an electrical control mechanism. The turntable base 3 is mounted on the foundation 1 via four adjustable feet 2, allowing adjustment of its height and level to ensure operational stability. The tray 6 is rotatably mounted on the turntable base 3 via a plane bearing 4 and a central bearing 5, ensuring the stability of the tray 6's rotation. The upper surface of the tray 6 is equipped with a panel made of 304 stainless steel, enabling it to withstand a maximum material load of 300 kg. The plane bearing 4 and the central bearing 5 are existing structures with simple lubrication and sealing mechanisms, facilitating routine lubrication maintenance and subsequent repairs.

[0023] The pallet 6 has three or four receiving buckets 7 arranged at equal arc intervals around its center, with the number of receiving buckets 7 selected according to the shift. The drive mechanism is connected to the pallet 6 and drives the pallet 6 to rotate. The electrical control mechanism controls the pallet 6 to rotate so that the corresponding receiving bucket 7 is located directly below the material feed pipe 17.

[0024] Preferably, the tray 6 is provided with the same number of limiting rings 14 as the receiving buckets 7. The limiting rings 14 are inserted into the lower part of the receiving buckets 7 to limit the placement of the receiving buckets 7 and ensure stability. The receiving buckets 7 are stainless steel buckets with a single bucket volume of 15L and a total weight of 15-45kg when the single bucket is full of product samples.

[0025] Specifically, the drive mechanism is mounted on the equipment base 1 via a bracket and located on one side of the tray 6. The drive mechanism includes a motor reducer 8, a drive pinion 9, and a reduction gear 10. The motor reducer 8 is fixed to the bracket, the drive pinion 9 is fixedly mounted on the output shaft of the motor reducer 8, and the reduction gear 10 is fixed to the circumferential surface of the tray 6. The drive pinion 9 and the reduction gear 10 mesh. When the motor reducer 8 operates, it drives the drive pinion 9 to rotate, which in turn drives the reduction gear 10 to rotate, thus achieving the rotation of the tray 6.

[0026] Specifically, the electrical control mechanism includes a PLC control box 11, a metal sensor 12, and a position sensor 13. The PLC control box is existing technology, integrating a PLC controller. The panel of the PLC control box 11 also includes a manual self-locking button, an emergency stop button, a power indicator light, shift indicator lights, and a display screen. The number of shift indicator lights matches the number of receiving bins 7, corresponding to shifts labeled A, B, C, or A, B, C, D. The display screen (preferably a touchscreen) allows staff to set the shift times for the morning, afternoon, and evening shifts.

[0027] The position sensor 13 is a 24V DC proximity switch. Three or four metal sensing plates 12 are fixed to the tray 6, corresponding to the positions of each receiving bin 7. The metal sensing plates 12 rotate synchronously with the tray 6. The position sensor 13 is fixed to the equipment foundation 1 or the turntable base 3 via a mounting bracket. The fixed position of the position sensor 13 varies, and it is located outside the tray 6 and electrically connected to the PLC control box 11. The PLC control box 11 is also electrically connected to the motor reducer 8. The position sensor 13 and the metal sensing plates 12 are at the same horizontal level, and the position sensor 13 is used to sense the metal sensing plates 12. When the position sensor 13 senses the metal sensing plate 12, the PLC control box 11 controls the motor reducer 8 to stop working. At this time, the receiving bin 7 corresponding to the metal sensing plate 12 is located directly below the material feed pipe 17. The motor reducer 8 is a reducer with built-in braking function, as is common in the prior art, to achieve precise positioning.

[0028] To prevent overflow of the receiving bucket 7 or dripping of material into the feed pipe 17, a water collection trough 15 is provided on the turntable base 3, and a water outlet connected to the water collection trough 15 is provided on the tray 6. A drain pipe 16 is installed at the bottom of the water collection trough 15, and the drain pipe 16 discharges the overflowing material to the corresponding collection place.

[0029] Workflow:

[0030] Automatic control mode: Operators preset the time nodes for the morning, afternoon, and evening shifts (e.g., 8:00, 16:00, 24:00, etc.) via the display screen (touchscreen). When the PLC controller detects that the current time has reached the preset shift time node, it sends a start signal to the motor reducer 8. The motor reducer 8 drives the tray 6 to rotate 120° (three shifts) or 90° (four shifts). During rotation, when the position sensor 13 senses the metal sensing plate 12, it sends a stop signal to the PLC controller. The PLC controller then stops the motor reducer 8, achieving precise switching and positioning of the receiving bucket 7. Simultaneously, when the receiving bucket 7 corresponding to a certain shift moves directly below the material feed pipe 17, the PLC controller controls the corresponding indicator light to illuminate red, clearly indicating the current receiving shift.

[0031] Manual control mode:

[0032] When the position of receiving bucket 7 needs to be manually adjusted, the operator can press the manual self-locking button on the PLC control box panel. The motor reducer 8 will start and drive the receiving bucket 7 tray 6 to rotate 120° (three shifts) or 90° (four shifts). When the position sensor 13 senses the metal sensing plate 12, the motor reducer 8 will stop running. In addition, if the position sensor 13 is damaged or malfunctions, the emergency stop button can be pressed to forcibly stop the equipment. The equipment can be restored to normal operation after the fault is eliminated.

[0033] The automatic shift-based turntable for product output and sample collection in the ore dressing plant enables automatic shift-based collection of product output and samples from different shifts, eliminating the need for manual switching of the collection bins and reducing the number of workers required in the ore dressing plant, thus lowering labor costs.

[0034] When the automatic control mode is used for the automatic shift-based receiving turntable of the mineral processing plant's product output and samples, it can accurately complete the switching of receiving bucket 7 according to the preset time nodes, avoiding shift-based errors caused by inaccurate time control during manual operation. This ensures the accuracy of product output statistics and sample testing results for different shifts, and provides reliable data support for evaluating the operational quality and efficiency of each shift.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
