Description
TECHNICAL FIELD
[0001] The utility model belongs to mineral processing instrument technical field, concretely relates to a kind of ore pulp deep groove sampler. BACKGROUND
[0002] Ore pulp liquid sample is mainly used to analyze the concentration of soluble metal ions and chemical agent residues in liquid phase to guide wastewater treatment process adjustment;At the same time, by detecting the content of suspended solids and turbidity, the effect of solid-liquid separation is evaluated and the settling time is optimized. In addition, the periodic comparison of liquid phase samples can verify the operation state of process equipment (such as the activity of catalytic tower), and ensure compliance with hazardous waste discharge standards (such as detection of HW08 class benzene series);
[0003] The existing deep groove sampling device generally adopts the form of open bottom and sealed extraction to take the bottom liquid sample, but in the field of mineral processing, a layer of concentrate foam is usually floated on the upper layer of flotation tank, and the upper layer of concentrate foam is easily mixed into the bottom ore pulp during sampling, causing sample contamination. At the same time, a deep groove sampler cannot be cleaned at one sampling point, otherwise it will also cause mutual contamination between samples, which will lead to poor representativeness of sampling and affect subsequent analysis and process adjustment.

Detailed Implementation
[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] like Figure 1 , Figure 2 As shown, a deep slurry sampler of this utility model includes a sampling bottle 1, a bottle cap 2 threadedly connected to the bottle mouth of the sampling bottle 1, a through hole 21 provided at the center of the bottle cap 2, a fixing ring 3 fixedly connected to the upper side of the bottle cap 2, a positioning cylinder 4 integrally connected to the upper side of the fixing ring 3, the positioning cylinder 4 is provided with a plurality of slurry inlet holes 5, a plug 6 is placed inside the positioning cylinder 4, the plug 6 is a combination of a cylinder and a frustum, when the upper end face of the plug 6 contacts the inner top surface of the positioning cylinder 4, the position of the slurry inlet hole 5 is located at the frustum part of the plug 6;
[0023] A rectangular tube 7 is integrally connected to the upper side of the positioning tube 4. A threaded sleeve 8 and a mating sleeve 9 are installed inside the rectangular tube 7. An adjusting tube 10 is slidably sleeved on the outer side of the rectangular tube 7. A locking screw 11 is threadedly connected to the adjusting tube 10. The end of the locking screw 11 contacts the rectangular tube 7. A retaining ring 12 is installed inside the adjusting tube 10. An end cap 13 is installed on the adjusting tube 10.
[0024] A threaded post 14 is integrally connected to the upper side of the plug 6. The threaded post 14 is threaded and matched with the threaded sleeve 8. An inner rod 15 is integrally connected to the upper side of the threaded post 14. A rotating rod 16 is slidably sleeved on the outer side of the inner rod 15. The outer diameter of the rotating rod 16 matches the mating sleeve 9. A retaining ring 17 is integrally connected to the rotating rod 16. The retaining ring 17 is located between the end cap 13 and the retaining ring 12. A rotating handle 18 is integrally connected to the rotating rod 16.
[0025] In this implementation case, when using a deep slurry sampler, the lengths of the rectangular cylinder 7 and the adjusting cylinder 10 are adjusted according to the sample depth to be obtained. The adjustment method is as follows: loosen the locking screw 11, then pull the adjusting cylinder 10 directly to the required length, and then lock it with the locking screw 11. Under the effect of the retaining ring 17, the lengths of the inner rod 15 and the rotating rod 16 will move accordingly, so it will not affect the transmission of force. It should be emphasized that the fit between the inner rod 15 and the rotating rod 16 cannot be circular, otherwise the rotating rod 16 will spin freely and cannot drive the inner rod 15 to rotate together. This point is not difficult for those skilled in the art to understand, and the corresponding structure is not difficult to implement.
[0026] After the length adjustment is completed, the sampling bottle 1 is screwed into the bottle cap 2, the handle 18 is rotated to drive the rotating rod 16 to rotate the threaded column 14, under the effect of the threaded sleeve 8, the plug 6 moves in position, so that the cylindrical area of the plug 6 is blocked into the pulp hole 5. In actual operation, the plug 6 is rotated to the bottom, and the plug 6 is in contact with the inlet end of the bottle cap 2. Then the sampling bottle 1 is directly inserted into the foam by holding the adjusting cylinder 10 with one hand, and the adjusting cylinder 10 is fixed so as not to rotate with the other hand. The plug 6 is moved away from the bottle cap 2 by rotating the handle 18, so that the cylindrical area of the plug 6 is away from the pulp hole 5, and the liquid enters the sampling bottle 1 through the pulp hole 5 and the through hole 21. Because it is below the foam, the foam cannot enter, and the sample is pure. After 1-3 minutes, the plug 6 is moved to block the through hole 21 again, and then it is pulled up. When passing through the foam layer, the foam cannot enter, ensuring the purity of the sample.
[0027] Preferably, a first sealing ring 19 is installed between the bottle cap 2 and the fixing ring 3. Such design increases the connection sealing between the bottle cap 2 and the fixing ring 3, prevents the foam from entering the sample in the sampling bottle 1, and actually can consider sealing measures according to specific circumstances.
[0028] Preferably, the fixing ring 3 is provided with a second sealing ring 20. Such design cooperates with the plug 6 to ensure the sealing effect of the plug 6. Actually, sealing measures can be considered according to specific circumstances.
[0029] Preferably, the outer side of the rectangular cylinder 7 is engraved with scale lines 21. Such design can accurately adjust the total length between the rectangular cylinder 7 and the adjusting cylinder 10, and then adapt to different sampling depths. Actually, measures for determining the length can be considered according to specific circumstances.
[0030] Preferably, the locking screw 11 has two. Such design strengthens the locking effect, prevents the length from changing during operation, and then affects the sampling depth. Actually, the number of locking screws 11 can be considered according to specific circumstances.
[0031] The above embodiments only exemplarily illustrate the principle and effect of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the present application should be covered by the claims of the present application.
