Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing detection, and particularly relates to a portable continuous pulp sampling device. Background Art

[0002] In recent years, the mine economy has been booming. As China's economy has shifted to a stage of high-quality development, the demand for mineral resources will continue to grow. Mineral resources are limited and non-renewable resources. Therefore, the efficient recovery and utilization of mineral resources have become crucial. Thus, in order to avoid unnecessary waste caused during the ore dressing process in mining production, it is necessary to analyze and inspect the pulp during the ore dressing production process, and dynamically monitor various production indicators in real time, so as to make timely adjustments to the process flow to obtain the maximum production efficiency.

[0003] However, the following problems exist in the current sampling process of production pulp samples: on the one hand, the sampling process mostly randomly selects multiple interval sampling operations at a certain fixed time point, but the time interval is usually long, and most of them are manual samplings, with a large difference in the sampling volume each time; on the other hand, when intercepting pulp samples at a certain depth in the intercepting device, the sample is easily contaminated by the upper-layer foam during the lifting process of the sampling tool, resulting in an incorrect pulp grade and ultimately distorted data. To avoid the problem of distorted data during the sampling process and ensure that the obtained samples are representative, we need a new type of scientific, effective, convenient and practical sampling tool to complete the sampling work. Summary of the Invention

[0018] Embodiment 1

[0019] A portable continuous pulp sampling device, comprising a motor 1, a sealed cylinder body 4, a screw rod 6, a cam 8, a spring 9, a linkage rod body 10, and a sealed rubber ring 11; wherein discharge ports 5 and a feed port 12 are respectively provided at the upper and lower ends of the sealed cylinder body 4, the upper and lower ends of the screw rod 6 are respectively connected in the sealed cylinder body 4 through bearings 3, and the top of the screw rod 6 passes through the sealed cylinder body 4 and is connected to the drive shaft of the motor 1 located at the top of the sealed cylinder body 4, and rotates under the drive of the motor 1. A cam 8 is sleeved outside the bottom of the screw rod 6 located inside the sealed cylinder body 4. One end of the linkage rod body 10 is located inside the sealed cylinder body 4 and contacts the cam 8, and a spring 9 is sleeved outside the linkage rod body 10 between the linkage rod body 10 and the sealed cylinder body 4. The other end of the linkage rod body 10 is located outside the sealed cylinder body 4, and a sealed rubber ring 11 is fixed thereon. The sealed rubber ring 11 is aligned with the feed port 12 and can block the feed port 12.

[0020] Rubber rings are provided on both the discharge port 5 and the feed port 12.

[0021] The motor 1 is fixed on the top of the sealed cylinder body 4 through a bracket.

[0022] A sealed rubber pad 7 is provided above the bearing 3 located below the inside of the sealed cylinder body 4. The sealed rubber pad 7 is sleeved outside the bearing 3, so as to form a seal between the bearing 3 and the sealed cylinder body 4.

[0023] The cam 8 is sleeved outside the screw rod 6 below the bearing 3 located below the inside of the sealed cylinder body 4.

[0024] The linkage rod body 10 includes a flat-bottomed follower and a connecting rod. The connecting rod is fixed to the connecting rod end of the flat-bottomed follower. The flat bottom end of the flat-bottomed follower is located inside the sealed cylinder body 4 and contacts the cam 8, and a spring 9 is sleeved outside the connecting rod end of the flat-bottomed follower between the flat bottom end of the flat-bottomed follower and the sealed cylinder body 4. The part of the connecting rod end of the flat-bottomed follower passing through the sealed cylinder body 4 is fixed with a connecting rod. The connecting rod is located outside the sealed cylinder body 4, and a sealed rubber ring 11 is fixed thereon.

[0025] The working process of the present utility model:

[0026] Start the motor 1. The motor 1 drives the screw 6 and the cam 8 to rotate, causing the cam 8 to move away from the flat follower of the linkage rod body 10. Under the pre-tightening force of the spring 9, the flat follower of the linkage rod body 10 moves towards the inside of the sealing cylinder body 4, thereby causing the sealing rubber ring 11 to approach the ore inlet 12 and block the ore inlet 12, preventing the ore pulp from entering the sealing cylinder body 4. Then insert the bottom of the sealing cylinder body 4 into the ore pulp to an appropriate depth, ensuring that the ore inlet 12 can be completely immersed in the ore pulp, and firmly fix the sampling device above the ore pulp to be sampled. Connect the sampling device to the discharge port 5. Start the motor 1. The rotation of the motor 1 drives the screw 6 and the cam 8 to rotate. The reciprocating movement of the cam 8 realizes the opening and closing of the ore inlet 12. Specifically: The motor 1 drives the screw 6 and the cam 8 to rotate, causing the cam 8 to approach the flat follower of the linkage rod body 10. Under the pre-tightening force of the spring 9, the flat follower of the linkage rod body 10 moves towards the outside of the sealing cylinder body 4, thereby causing the sealing rubber ring 11 to move away from the ore inlet 12 and unseal the ore inlet 12. The ore pulp enters the sealing cylinder body 4. The liquid level of the ore pulp entering the sealing cylinder body 4 gradually rises. At the same time, under the transportation of the screw 6, it slowly reaches the top of the sealing cylinder body 4 and is discharged at the discharge port 5 and enters the sampling device to complete the sampling.

[0027] Embodiment 2

[0028] As Figure 1 、 2 shown, a portable continuous ore pulp sampling device includes a motor 1, a control panel 2, bearings 3, a sealing cylinder body 4, a discharge port 5, a screw 6, a sealing rubber pad 7, a cam 8, a spring 9, a linkage rod body 10, a sealing rubber ring 11, and an ore inlet 12.

[0029] A circular discharge port 5 and an ore inlet 12 are respectively arranged at the upper and lower ends of the sealing cylinder body 4. Both the discharge port 5 and the ore inlet 12 are wrapped with rubber rings and extend to the outer end. The control panel 2 can control the rotation speed of the motor 1, set the sampling duration, and the start frequency of the motor 1. The motor 1 is connected to the rotating screw 6. The screw 6 is fixed in the sealing cylinder body 4 by two upper and lower bearings 3. The lower end of the screw 6 is connected to the cam 8, and the upper end structure of the sealing cylinder body 4 is ensured to be airtight through the sealing rubber pad 7.

[0030] The sealing cylinder body 4 is divided into upper and lower parts by the sealing rubber pad 7. The upper part of the cavity is equipped with the screw 6. There are circular openings at both the upper and lower ends of the cavity, which are the discharge port 5 and the ore inlet 12 respectively. Both ends of the screw 6 are fixed in the sealing cylinder body 4 by bearings 3. The upper end of the screw 6 is connected to the driving motor 1, and the lower end of the screw 6 is connected to the cam 8. The cam 8 is located in the lower part of the cavity of the sealing cylinder body 4. The cam 8 and the linkage rod body 10 form a cam structure and perform reciprocating horizontal movement driven by the motor 1. The vertical end of the linkage rod body 10 is equipped with a sealing rubber ring 11. The center of the sealing rubber ring 11 and the center of the ore inlet 12 are on the same horizontal plane, and the inner diameter of the sealing rubber ring 11 is larger than the outer diameter of the rubber ring at the ore inlet 12.

[0031] Working process of the utility model:

[0032] Before sampling, it is necessary to ensure that the ore inlet 12 is fastened by the sealing rubber ring 11 on the linkage rod body 10. Insert the bottom of the sealing cylinder body 4 into the appropriate depth of the pulp. It is necessary to ensure that the ore inlet 12 can be completely immersed in the pulp, and the sampling device is stably fixed above the pulp to be sampled. Connect the discharge port 5 to the sample collecting device, connect the equipment to the power supply, and set the sampling duration and sampling frequency by controlling the working duration and rotation frequency of the motor 1. The rotation of the motor 1 drives the screw rod 6 and the cam 8 to rotate. The reciprocating motion of the cam 8 realizes the opening and closing of the ore inlet 12. Specifically: the linkage rod body 10 is a flat-bottom follower. Under the rotation of the spring 9 and the cam 8, the linkage rod body 10 is driven to move parallel. A sealing rubber ring 11 is installed at the other end of the linkage rod body 10. When the cam 8 moves away from the flat bottom, the spring 9 elongates, and the sealing rubber ring 11 on the linkage rod body 10 fastens the rubber ring on the ore inlet 12 at the bottom end of the sealing cylinder body 4, and the pulp cannot enter the sealing cylinder body 4; when the cam 8 approaches the flat bottom, the spring 9 is compressed, and the sealing rubber ring 11 on the linkage rod body 10 moves away from the rubber ring on the ore inlet 12 at the bottom end of the cylinder body 4, and the pulp enters the sealing cylinder body 4. The pulp entering the sealing cylinder body 4 is transported to the top of the sealing cylinder body 4 by the screw rod 6 and discharged at the discharge port 5 and enters the sample collecting device to complete the sampling.
