Description

Technical Field

[0001] The utility model relates to a slurry sampling device, which is mainly used for obtaining slurry samples at the bottom of certain equipment in ore dressing production. Background Art

[0002] Sampling and analysis are crucial tools for mineral processing production control and management. Sample data can be used to calculate various production metrics and identify issues within the production process. Therefore, sampling must be accurate and representative. Currently, commonly used samplers are flat-mouthed or round-mouthed sampling spoons, which ensure accurate sampling in most sampling scenarios.

[0003] However, as mineral processing equipment becomes increasingly large-scale, large-diameter ball mills and large-capacity flotation machines are increasingly widely used. The accompanying intermediate tanks and pump sump facilities are becoming deeper and deeper, making slurry sampling increasingly difficult. Furthermore, the slurry undergoes a sedimentation and segregation process within the pump sump or intermediate tank, and the metal grade or concentration of the surface slurry often fails to accurately reflect the slurry flowing through it. Using commonly used flat-mouthed or round-mouthed sampling spoons, the openings cannot be closed, so they can only sample the surface slurry and are unable to successfully obtain representative slurry from the deep outlets of the intermediate tanks or pump sump. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a deep slurry sampler, which is used for sampling slurry in the deep part of certain equipment in mineral processing production, so as to ensure the sampling accuracy and representativeness.

[0005] The technical solution of the utility model is as follows:

[0006] A deep slurry sampler comprises a main handle with a slurry bucket fixedly connected at its lower end, the slurry bucket having a circular opening facing upward at its upper end, at least two sleeves fixedly mounted on one side of the main handle; a secondary handle parallel to the main handle is slidably mounted in the sleeve up and down; a rubber plug for sealing the circular opening of the slurry bucket is connected to the lower end of the secondary handle via a connecting frame.

[0007] Preferably, the connecting frame includes a longitudinal frame coaxially arranged with the rubber stopper and fixed to the rubber stopper at the lower end, and a transverse frame with one end fixedly connected to the longitudinal frame and the other end fixedly connected to the lower end of the auxiliary handle.

[0008] Further preferably, the sampler also includes a cross bar fixed to the upper end of the main handle; a limit groove is provided on the upper side of the cross bar, which is perpendicular to the main handle and parallel to the transverse frame; a limit block for being clamped in the limit groove is fixedly installed on the secondary handle; when the limit block is parallel to the cross bar and the limit block is located directly above the cross bar, the rubber stopper is directly opposite the upper end of the slurry barrel.

[0009] More preferably, the limiting groove is a triangle with an opening facing upward; the limiting block is an inverted triangle with a shape matching the limiting groove; and the lower side ridges of the limiting block are vertically opposite to the bottom of the limiting groove.

[0010] The positive effects of this utility model are:

[0011] First, by pressing down and pulling up on the auxiliary handle, the slurry barrel can be completely closed or opened. After sampling, the barrel is immediately closed to prevent interference from surface slurry settling and segregation. This allows for the acquisition of a representative slurry sample at the intermediate tank or the bottom outlet of the pump sump. This simple and easy-to-use sampler is extremely helpful for sampling tasks such as on-site process inspections in mineral processing production. Accurate sampling data can help identify production issues on-site and prevent failures caused by sampling errors, saving manpower and resources.

[0012] Second, in the optimized technical solution of the present invention, the lower ribs of the limit block are vertically aligned with the bottom line of the limit slot, and during the lowering process of the limit block, its side slopes cooperate with the corresponding slopes of the limit slot. When the lower ribs of the limit block are vertically aligned with the bottom line of the limit slot, the rubber stopper and the upper end of the slurry barrel are also vertically aligned. This solves the technical problem of the difficulty of visually distinguishing the relative positional relationship between the rubber stopper and the slurry barrel due to the poor transparency of the slurry, and avoids the tedious operation of repeatedly rotating the auxiliary handle to adjust the circumferential position of the rubber stopper. This not only further improves operational efficiency, but also shortens the time it takes for the rubber stopper to seal the slurry barrel, further preventing sedimentation in the shallow slurry from entering the slurry barrel and affecting sampling accuracy.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 The embodiment of the present utility model includes a main handle 1 having a slurry bucket 8 fixedly connected to the lower end via a connecting plate 9, and the slurry bucket 8 has a circular opening at the upper end thereof opening upward.

[0018] At least two (two in this embodiment) sleeves 5 are fixedly mounted on one side of the main handle 1, running parallel to the main handle 1. A secondary handle 4, running parallel to the main handle 1, is slidably mounted in the sleeve 5. The lower end of the secondary handle 4 is connected to a rubber stopper 7 via a connecting frame 6, which is used to seal the circular opening of the slurry barrel 8.

[0019] Specifically, the connecting frame 6 includes a longitudinal frame 6-2 which is coaxially arranged with the rubber plug 7 and whose lower end is fixed to the rubber plug 7, and a transverse frame 6-1 which has one end fixedly connected to the longitudinal frame 6-2 and the other end fixedly connected to the lower end of the auxiliary handle 4.

[0020] Before sampling, first press down on the secondary handle 4 to completely seal the rubber stopper 7 against the slurry bucket 8. Then, insert the device into the appropriate sampling position at the bottom of the sampling tank. Lift the secondary handle 4 upward to separate the rubber stopper 7 from the slurry bucket 8. The upper end of the slurry bucket 8 is open, allowing the slurry at the bottom of the tank to enter the slurry bucket 8 through its upper port. Then, quickly press down on the secondary handle 4 to reseal the rubber stopper 7. After removing the entire sampling device from the slurry tank while maintaining the closed position, lift the secondary handle 4 upward to separate the rubber stopper 7 from the slurry bucket 8. Pour the extracted slurry sample into a designated container for storage pending analysis.

[0021] The above structure, combined with operational experience, essentially achieves the goal of deep-seated ore sampling in this utility model. However, due to the low transparency of the ore slurry, the relative position of the rubber stopper and the slurry barrel is difficult to discern visually. Sometimes, ensuring alignment of the rubber stopper with the upper end of the slurry barrel is difficult based solely on operational experience. Repeated rotation of the secondary handle is required to adjust the circumferential position of the rubber stopper (the circumferential position refers to the position of a circle centered at a point on the secondary handle axis) to ensure accurate insertion and alignment of the rubber stopper with the upper end of the slurry barrel. This repeated adjustment not only reduces operational efficiency but also prolongs the time it takes for the rubber stopper to seal the slurry barrel, causing sediment from shallow slurry to enter the barrel, impacting sampling accuracy.

[0022] In order to solve the above problems, further simplify the operation, and improve the sampling efficiency and accuracy, the optimized embodiment of the present invention further includes a cross bar 2 fixed to the upper end of the main handle 1. A limit groove 2-1 is provided on the upper side of the cross bar 2, which is perpendicular to the main handle 1 and parallel to the cross frame 6-1. Correspondingly, a limit block 3 for clamping in the limit groove 2-1 is fixedly installed on the auxiliary handle 4. The lower edge of the limit block 3 is higher than the upper edge of the top sleeve 5, and the lower edge of the limit block 3 is higher than the upper edge of the cross bar 2. By adjusting the connecting plate 9, it is ensured that when the limit block 3 is parallel to the cross bar 2 and the limit block 3 is located directly above the cross bar 2, the rubber stopper 7 and the upper end of the slurry barrel 8 are also directly opposite each other. In other words, the center line of the cross bar 2 intersects with the axis of the circular opening of the slurry barrel 8.

[0023] To ensure precise alignment between the stopper 3 and the stopper slot 2-1, the stopper slot 2-1 is designed as a triangle with an upward opening (a triangular longitudinal section). Accordingly, the stopper 3 is designed as an inverted triangle (an inverted triangular longitudinal section) that matches the stopper slot 2-1. As the stopper 3 descends, its side slopes mate with the corresponding slopes of the stopper slot 2-1.

[0024] The lower ribs of the stopper block 3 align vertically with the bottom line of the stopper groove 2-1. When the lower ribs of the stopper block 3 align vertically with the bottom line of the stopper groove 2-1, the rubber stopper and the upper end of the slurry barrel also align vertically. In other words, the extended line of the bottom line of the stopper groove 2-1 intersects the circular opening axis of the slurry barrel 8.
