Description

TECHNICAL FIELD

[0002] At present, most of the domestic and foreign mining enterprises choose flotation as the main beneficiation process, and ore pulp sampling is an important way to measure the effect of flotation process. At present, the sampling methods are divided into automatic sampling and manual sampling, and due to the limitation of site and cost, automatic sampling is only suitable for some specific sampling points, and more ore pulp sampling is completed by manual sampling. The tool used for manual sampling is a conical sampling spoon with narrow upper part and wide lower part. The shape of narrow upper part and wide lower part can prevent the ore pulp sample at a certain liquid level from being disturbed by other liquid levels, and in some places where sampling is difficult, the ore pulp sample can be guaranteed not to spill out. However, manual sampling cannot guarantee the uniformity of sampling, and the sampling result is greatly affected by the sampling personnel.

[0031] The handle 10 includes a fixed rod and a movable rod; the fixed rod is fixed on the connecting piece, the upper end of the connecting rod 13 is hinged to one end of the movable rod through a rotating pulley 9, the middle part of the movable rod is hinged to the connecting piece through another rotating pulley 9, and the fixed rod and the movable rod are arranged adjacent to each other. The handle 10 is composed of the fixed rod and the movable rod to form a V-shaped handle 10. When operating, the fixed rod and the movable rod are held by hand, and the movable rod is forced to move, so that the connecting rod 13 moves to lift or lower the layered sample storage pipe 2.

[0032] The handle 10 is made of stainless steel, with a radius of 30 mm; the connecting rod 13 is a cylindrical structure, with a radius of 30 mm; the rotating pulley 9 is made of stainless steel, with a radius of 30 mm; the water pipe 11 is made of stainless steel, with a model of DN50; and the deslagging valve 12 is made of stainless steel, with a model of DN50.

[0033] In this embodiment, the first sampling hole 8 of the layered sample storage chamber is located at the highest position in front of each layer of the sample storage chamber, the first sample discharge hole 4 is located at the lowest position to the right of each layer of the sample storage chamber, and the first flushing hole 6 is located at the highest position behind each layer of the sample storage chamber.

[0034] The distance between the upper and lower sampling holes, the upper and lower sample discharge holes, and the upper and lower flushing holes is 400 mm. The setting of the shell pipe 1 and the layered sample storage pipe 2 can facilitate production and use. The setting of the three types of hole positions can meet the requirements of the particle size and fluidity of the ore slurry and the requirement of the flushing water volume during use. Each component is made of stainless steel, which can reduce the impact of the acidity of the ore slurry and is not prone to rust, thereby prolonging the service life. The V-shaped handle 10 is a cylindrical structure with a radius of 30 mm, which is convenient to hold and reduces the damage to the palm.

[0035] During sampling, the V-shaped handle 10 is held, the connecting rod 13 is driven to move upward, and then the layered sample storage pipe 2 is driven to move upward. The first sampling hole 8 of each layer of the sample storage chamber corresponds to and overlaps with the second sampling hole 7 of the same level of the shell pipe 1. The first sample discharge hole 4 of each layer of the sample storage chamber also corresponds to and overlaps with the second sample discharge hole 3 of the same level of the shell pipe 1. The sample discharge hole is opened, and the balanced air pressure allows the layered ore slurry to smoothly enter each layer of the sample storage chamber from the sampling hole. The first flushing hole 6 of each layer of the sample storage chamber also corresponds to and overlaps with the second flushing hole 5 of the shell pipe 1. The flushing hole is opened. Since the flushing hole is located at the highest position behind each layer of the sample storage chamber, it will not cause the ore slurry to flow backward and will not affect sampling. The flushing hole is connected to the water pipe 11 (which can be referred to as a flushing pipe). Opening the flushing hole during sampling can balance the air pressure and allow the layered ore slurry to smoothly enter each layer of the sample storage chamber from the sampling hole. The three sampling holes are opened (the first sampling hole 8 corresponds to and overlaps with the second sampling hole 7), and the ore slurry samples of each layer are respectively stored in the three sample storage chambers. After the sampling operation is completed, the handle 10 is released, the connecting rod 13 and the layered sample storage pipe 2 move downward, the sampling hole, the sample discharge hole, and the flushing hole are closed, and the ore slurry samples are stored in each layer of the layered sample storage chamber, thereby completing the sampling.

[0036] When the sample unloading operation is performed, the V-shaped handle 10 is held, the movable rod drives the connecting rod 13 to move upward, and then drives the layered sample storage tube 2 to move upward. The first sample placing hole 4 of each sample storage chamber is coincided with the second sample placing hole 3 of the same layer of the outer shell tube 1. The first sample taking hole 8 of each sample storage chamber is also coincided with the second sample taking hole 7 of the same layer of the outer shell tube 1. The sample taking hole is opened, and the balance pressure makes the taken ore pulp sample flow out of the sample placing hole smoothly. The first flushing hole 6 of each layered sample storage chamber is also coincided with the second flushing hole 5 of the outer shell tube 1. The flushing hole is opened. Since the flushing hole is located at the highest position behind each sample storage chamber, it will not cause the ore pulp to flow backward, and has no effect on the sample placing. The flushing hole is connected with the water pipe 11 (which can be called a flushing pipe). When the sample placing is performed, the flushing hole is opened to balance the pressure and make the layered ore pulp sample flow out of the sample placing hole smoothly. The three sample placing holes are opened (the first sample placing hole 4 is coincided with the second sample placing hole 3), and the taken ore pulp samples of each layer flow out of the sample placing holes of the three sample storage chambers, and the sample unloading operation is completed.

[0037] When the cleaning operation is performed, the V-shaped handle 10 is held, the movable rod drives the connecting rod 13 to move upward, and then drives the layered sample storage tube 2 to move upward. The first flushing hole 6 of each sample storage chamber is coincided with the second flushing hole 5 of the same layer of the outer shell tube 1. The first sample taking hole 8 of each sample storage chamber is also coincided with the second sample taking hole 7 of the same layer of the outer shell tube 1. The sample taking hole is opened, and the balance pressure makes the taken ore pulp sample flow out of the sample placing hole smoothly. The first flushing hole 6 of each sample storage chamber is also coincided with the second flushing hole 5 of the same layer of the outer shell tube 1. The flushing hole is opened. Since the flushing hole is located at the highest position behind each sample storage chamber, it will not cause the ore pulp to flow backward, and has no effect on the sample placing. The flushing hole is connected with the water pipe 11 (which can be called a flushing pipe). When the sample placing is performed, the flushing hole is opened to balance the pressure and make the layered ore pulp sample flow out of the sample placing hole smoothly. The three sample placing holes are opened (the first sample placing hole 4 is coincided with the second sample placing hole 3), and the taken ore pulp samples of each layer flow out of the sample placing holes of the three sample storage chambers, and the sample unloading operation is completed.
