Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to an overflow type deep tank flotation machine pulp sampling device. Background Art

[0002] In the process of mining production, it is necessary to adjust the mineral processing process in time according to the actual production situation, especially the flotation process. It is necessary to regularly sample, wash, test and analyze the flotation pulp, evaluate the real-time flotation situation, and timely adjust the flotation reagents, pulp materials and process flow. At present, most companies use containers of various shapes for sampling, which have the problems of poor sampling representativeness and instability. When sampling, the flotation concentrate is easy to enter the open sampling container, and the pulp volume is unstable. Especially for large-scale flotation machines with large flotation tank depth, the sampling results fluctuate greatly. In addition, when measuring the concentration, a certain volume of pulp needs to be taken. At this time, the sampler either takes a part of the pulp more or samples in multiple times to obtain a certain volume of pulp. When the sampler takes the sample from the flotation machine, the coarser ore particles in the pulp quickly sink to the bottom of the sampler, resulting in errors in the process of transferring the pulp to the concentration pot. Therefore, a pulp sampling device for a deep tank flotation machine is invented to improve the sampling accuracy, which is of great significance to the control of mineral processing indicators.

[0021] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0022] The following is combined with Figure 1 This application is described in further detail.

[0023] The embodiment of the present application discloses a slurry sampling device for an overflow deep tank flotation machine.

[0024] Reference Figure 1 The overflow type deep tank flotation machine slurry sampling device includes a pumping component, a lifting component and a sample receiving component; the pumping component includes a slurry pump 1 and a pumping motor 2 for driving the slurry pump 1 to operate, the inlet of the slurry pump 1 is connected with a slurry suction pipeline, and a slurry suction port is formed at one end of the slurry suction pipeline away from the slurry pump 1; the sample receiving component includes a delivery pipe 3 connected to the outlet of the slurry pump 1, and a sample receiver 4 is provided at one end of the delivery pipe 3 away from the slurry pump 1; the lifting component drives the slurry suction pipeline to move to adjust the position of the slurry suction port.

[0025] The slurry pump 1 is operated by the pumping motor 2 to extract the slurry from the deep tank flotation machine. After passing through the slurry extraction pipeline, a slurry extraction port is formed at the end away from the slurry pump 1. Then the slurry is sent to the sampler 4 through the delivery pipe 3 to realize the sampling operation. The lifting component drives the slurry extraction pipeline to move and adjusts the position of the slurry extraction port so that it can adapt to the sampling needs of different positions and depths. The role of this design is to avoid the contamination of the ore sample by the foam concentrate on the liquid surface by directly extracting the slurry from below the liquid surface, thereby ensuring the accuracy of sampling; secondly, through the action of the lifting component, the position of the slurry extraction port can be adjusted to realize translation or lifting operation, so as to obtain samples at different positions and depths more flexibly during sampling, thereby improving the detection accuracy and representativeness of sampling. Therefore, such a design helps to improve the sampling accuracy and ensure the effective adjustment of the flotation process, thereby providing key support for the optimization of mineral processing in the mining production process.

[0026] The lifting assembly includes a fixed frame 5 and a moving seat 6 slidably connected to the fixed frame 5 . A driving motor 7 is provided on the fixed frame 5 . The driving motor 7 is connected to the moving seat 6 through a transmission structure to drive the moving seat 6 to slide along the fixed frame 5 .

[0027] When the drive motor 7 is started, the transmission structure transmits power to the mobile seat 6, causing it to perform translational motion on the fixed frame 5, thereby adjusting the position of the slurry extraction port relative to the deep tank flotation machine. The purpose of this design is that through the sliding movement of the mobile seat 6, the position of the slurry extraction port can be flexibly adjusted to meet the sampling requirements of different positions and depths, thereby improving the accuracy and representativeness of the sampling. At the same time, the drive motor 7 can accurately control the sliding process of the mobile seat 6 through the action of the transmission structure, ensuring the accuracy and stability of the sampling operation, and providing key support for the effective operation of the slurry sampling device.

[0028] The transmission structure is one of a chain structure, a gear rack mechanism or a belt 12 wheel mechanism. The function of these transmission structures is to transmit the power of the drive motor 7 to the mobile seat 6 so as to adjust the position of the slurry extraction port. Specifically, the chain structure converts the rotational motion into linear translational motion through the cooperation of the chain and the gear, so that the mobile seat 6 can be translated along the fixed frame 5. The gear rack mechanism realizes transmission and position adjustment through the meshing of the gear and the rack. The belt 12 wheel mechanism uses the cooperation of the belt 12 and the wheel group to transmit the rotational force of the motor to the mobile seat 6, so that it slides along the fixed frame 5. Such a design plays a key role in the slurry sampling device: it can effectively transmit the power of the motor to the mobile seat 6, realize the precise adjustment of the position of the slurry extraction port, and provide necessary support for the sampling operation. In addition, these transmission structures can also ensure that the movement of the mobile seat 6 is stable and reliable, thereby ensuring the accuracy and stability of the sampling process, and improving the working efficiency and sampling accuracy of the entire deep tank flotation machine slurry sampling device.

[0029] In a specific embodiment, the fixed frame 5 is arranged vertically, the movable seat 6 is slidably matched with the fixed frame 5 vertically, and the lifting assembly drives the slurry extraction pipeline to move to adjust the height of the slurry extraction port. When the lifting assembly is started, the movable seat 6 slides vertically along the fixed frame 5, changes the position of the slurry extraction pipeline, and then changes the height of the slurry extraction port relative to the deep tank flotation machine. By sliding the movable seat 6 vertically, the height of the slurry extraction port can be flexibly adjusted to meet the sampling requirements of different depths. This design can ensure the accuracy and precision of the sampling operation and help improve the representativeness and detection accuracy of the sampling.

[0030] In another specific embodiment, the fixed frame 5 is arranged horizontally, the movable seat 6 slides with the fixed frame 5 in the horizontal direction, and the lifting assembly drives the slurry extraction pipeline to move to adjust the horizontal position of the slurry extraction port. When the lifting assembly is started, the movable seat 6 slides horizontally along the fixed frame 5 to change the position of the slurry extraction pipeline, thereby adjusting the horizontal position of the slurry extraction port relative to the deep tank flotation machine. By sliding the movable seat 6 horizontally, the horizontal position of the slurry extraction port can be flexibly adjusted to meet the sampling requirements of different positions. This design can ensure the accuracy and precision of the sampling operation and improve the representativeness and detection accuracy of the sampling.

[0031] The slurry extraction pipeline includes two sections of hard pipes 8 and one section of flexible pipe 9. The two ends of the flexible pipe 9 are respectively connected to a section of hard pipe 8. One hard pipe 8 is connected to the slurry pump 1. A slurry extraction port is formed on the other hard pipe 8. The hard pipe 8 with the slurry extraction port is fixed on the movable seat 6. When the lifting assembly is started, the movable seat 6 slides along the fixed frame 5, causing the lateral position of the slurry extraction port to change. By adjusting the expansion and contraction of the flexible pipe 9, the slurry extraction port can be moved and adjusted in the lateral direction. Through the elasticity and expansion and contraction characteristics of the flexible pipe 9, the slurry extraction port can be flexibly adjusted in the lateral position to meet the sampling requirements of different depths and liquid surface positions. At the same time, fixing the hard pipe 8 with the slurry extraction port on the movable seat 6 can ensure the stability and accuracy of the slurry extraction port position and improve the accuracy and reliability of the sampling operation. This design helps to effectively adjust the position of the slurry extraction port and ensure the stability and accuracy of the sampling process.

[0032] A pipe connector 10 is provided between the hard pipe 8 and the flexible pipe 9, and the pipe connector 10 is detachably connected to the hard pipe 8 and the flexible pipe 9, respectively. When disassembly is required, the pipe connector 10 can be easily separated from the hard pipe 8 and the flexible pipe 9. Such a design makes the entire slurry extraction pipeline more flexible, convenient for maintenance, cleaning and replacement of pipeline components, and also helps to adjust the length and position of the pipeline. The detachable connection of the pipe connector 10 simplifies the maintenance and maintenance process of the slurry extraction pipeline, and improves the convenience and efficiency of operation. At the same time, the ability to quickly disassemble and replace the pipe connector 10 makes the system more reliable and flexible, reduces downtime caused by pipeline failure or maintenance, and ensures the normal operation and continuous operation of the slurry sampling device.

[0033] In a specific embodiment, the pipe connector 10 is connected to the hard pipe 8 and the flexible pipe 9 through a flange structure. The pipe connector 10, the hard pipe 8 and the flexible pipe 9 are tightly fixed together by flanges and bolts to form a stable connection. When disassembly is required, the connector, the hard pipe 8 and the flexible pipe 9 can be easily separated by loosening the bolts on the flange. Such a design can ensure that the slurry extraction pipeline is firmly connected during use, avoid leakage and loosening, and improve the safety and stability of the system. Through the flange structure connector, the installation and disassembly process of the pipeline can be simplified, the time and workload of maintenance and replacement of parts can be reduced, and the operating efficiency can be improved. In addition, the flange connection also has good sealing performance, which effectively prevents slurry leakage, ensures the normal operation of the slurry sampling device and the continuity of the production process.

[0034] The transmission structure includes two rollers 11 respectively arranged at the two ends of the fixed frame 5, a belt 12 is tensioned between the two rollers 11, the movable seat is fixed on the belt 12, and the output shaft of the drive motor 7 is connected to one roller 11. When the drive motor 7 is started, the output shaft drives one roller 11 to rotate, and the motion is transmitted to the other roller 11 through the tensioned belt 12, so that the movable seat moves along the guide track on the fixed frame 5. Through the transmission of the rollers 11 and the belt 12, the rotational force of the drive motor 7 is transmitted to the movable seat, thereby driving the movable seat to perform linear reciprocating motion on the fixed frame 5. Such a transmission structure can provide reliable power transmission and smooth motion control, which is used to adjust the position of the slurry extraction port or other equipment, and meet the needs of position adjustment and motion control in mining production.

[0035] A slide groove is provided on the fixed frame 5 along the length direction, and the movable seat 6 passes through the slide groove and slides with the slide groove. The end of the movable seat 6 located inside the slide groove is connected to the belt 12, and the end of the movable seat 6 located outside the slide groove is connected to the slurry extraction pipeline. Through the structure of the slide groove and the movable seat 6, the slurry extraction port is precisely adjusted in the length direction. The slide groove can guide the movable seat 6 to improve the sliding stability of the movable seat 6.
