Description

Technical Field

[0001] The utility model belongs to the technical field of concentrators, and in particular relates to a sampling device for a concentrated clear water layer of a concentrator. Background Art

[0002] A thickener is a type of thickening equipment used in industrial production for ore washing, mineral processing, sewage treatment, coal washing, and other purposes. During operation, the slurry is washed by a rotating rake in the thickening tank. As the ore is washed, a large amount of sludge settles at the bottom of the thickening tank. The scrapers on the rake scrape the settled sludge toward the center of the thickening tank.

[0003] Furthermore, during the concentration process, chemical additives, such as flocculants, are often added to the concentration tank to improve the ore washing process. Consequently, as the concentration and washing process progresses, the denser ore sludge in the tank gradually sinks, while the upper water layer in the tank gradually becomes clearer due to the gradual settling of impurities. Therefore, during the concentration process, the clear water layer in the concentration tank is often sampled and tested for clarity and impurity content to determine the concentration and treatment effectiveness of the material and whether it meets the standards for recyclability.

[0004] Sampling requires operators to collect samples from various locations within the concentrator. Traditionally, operators lower fixed sampling bottles into the slurry using a sling and take samples from various locations within the concentrator. After sampling, the clarity of the clear water layer and the amount of suspended solids present are observed to assess the progress of the concentrator's processing.

[0005] However, it is obvious that the above sampling method is not only very inefficient, but also difficult to fully sample the clear water layer in the concentration due to the large volume and large perimeter of the concentration tank. Utility Model Content

[0006] Based on the above background, the purpose of the present invention is to provide a sampling device for the concentrated clear water layer of a concentrator.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A sampling device for a concentrated clear water layer of a concentrator, comprising a rolling and crawling mechanism that rolls and crawls at the mouth of a concentration tank, wherein a sampling mechanism is assembled and connected to the rolling and crawling mechanism;

[0009] The rolling crawling mechanism includes a crawling frame; the sampling mechanism includes vertical arms fixedly connected to both sides of the top of the crawling frame, a rotating shaft is rotatably connected between the vertical arms, a rotating swing frame is fixedly connected to the rotating shaft, the rotating swing frame is hinged to a hanging arm, and the lower end of the hanging arm is hinged to a long sampling tube;

[0010] The climbing frame is fixedly assembled with a driving motor that drives the rotating shaft;

[0011] The long sampling tube is provided with a plurality of sampling holes spaced apart from each other.

[0012] During the sampling process, the driving motor drives the rotary swing frame to rotate, and the crane arm flips over to immerse the long sampling tube into the clear water layer of the concentration tank for sampling. After sampling, the driving motor drives the rotary swing frame to rotate, and the crane arm lifts the long sampling tube above the liquid surface.

[0013] Preferably, both sides of the climbing frame are respectively fixedly assembled with a crawling assembly that rolls against the inner and outer walls of the concentration tank, and the crawling assembly includes a rotary turning motor fixedly installed at the bottom of the climbing frame, and the output shaft of the rotary turning motor is fixedly assembled with a resisting arm;

[0014] The supporting arm is rotatably connected with a supporting roller that contacts the side wall of the concentration tank, and the bottom of the supporting arm is equipped with a motor that drives the supporting roller to rotate.

[0015] Preferably, a fixed arm is fixedly connected to the bottom of the climbing frame;

[0016] The output shaft of the rotary turning motor is rotatably connected to the fixed arm.

[0017] Preferably, the longitudinal cross-section of the support arm is L-shaped, the top of the support arm is fixedly connected to a fixing seat, and the output shaft of the rotary turning motor is fixedly connected to the fixing seat.

[0018] Preferably, the bottom of the climbing frame is fixedly connected to a bottom motor seat, and the rotary turning motor is fixedly mounted on the bottom motor seat via a plurality of connecting screws.

[0019] Preferably, the rotating swing frame includes swing rod portions spaced apart on both sides, and the inner ends of the swing rod portions are fixedly connected to the rotating shaft;

[0020] The outer end of the swing arm portion is integrally formed with a vertical portion vertically arranged toward the inside, a hinge shaft is rotatably connected between the vertical portions, and the boom is fixedly connected to the hinge shaft.

[0021] Preferably, the bottom of the boom is fixedly connected to a U-shaped hinge seat, and both ends of the long sampling tube are respectively fixedly connected to pins hinged on the U-shaped hinge seat.

[0022] Preferably, the central portion of the climbing frame is rotatably connected to a supporting wheel;

[0023] The supporting rotating wheel includes a rotating shaft rotatably connected to the climbing frame, a rotating wheel frame is fixedly connected to the bottom of the rotating shaft, and a roller is rotatably connected to the rotating wheel frame.

[0024] Preferably, a motor bracket for mounting the drive motor is fixedly connected to the outer side wall of the climbing frame.

[0025] The utility model has the following beneficial effects:

[0026] 1. During the working process, when the entire device moves in a circle on the pool mouth of the concentration tank through the rolling crawling mechanism, when it moves to a certain distance, at this time, the driving motor (the driving motor is a forward and reverse motor disclosed in the prior art) drives the rotating swing frame to flip downward until the sampling long tube descends. Since the sampling long tube is arranged in a hinged manner, the sampling long tube remains in a vertical state.

[0027] The sampling tube is flipped over to immerse in the clear water layer and then sampled. This method allows for flexible and efficient sampling of the clear water layer.

[0028] At the same time, the sampling point is controlled by the length of the crawling track of the rolling crawling mechanism. Therefore, in the actual production process, samples can be taken at most positions in the concentration tank, thereby accurately reflecting the concentration process of the concentration tank through the condition of the clear water layer.

[0029] 2. Real-time sampling is achieved during the sampling mechanism's circumferential motion. Specifically, during operation, the rollers on both sides press against the inner and outer walls of the concentrator tank. The friction between the rollers and the concentrator tank creates circumferential motion. Simultaneously, the direction of motion is adjusted through continuous rotation. Specifically, a rotating steering motor drives the arm to continuously rotate, adjusting the angle of the crawling assembly, thereby achieving circumferential motion around the concentrator tank. This continuous circumferential motion enables real-time sampling. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] like Figure 1-5 As shown, a sampling device for the concentrated clear water layer of a concentrator includes a rolling and crawling mechanism that rolls and crawls at the mouth of a concentration tank, and a sampling mechanism is assembled and connected to the rolling and crawling mechanism.

[0042] During operation, the rolling crawling mechanism enables the entire device to move in a circular motion around the pool opening of the concentration tank. During this motion, the sampling mechanism samples the clear water layer in the concentration tank. This method solves the problem of heavy workload and difficulty in sampling the clear water layer of large concentration tanks.

[0043] Specifically, the rolling crawling mechanism includes a crawling frame 1; the sampling mechanism includes vertical arms 442 (located on the top right) fixedly connected to both sides of the top of the crawling frame 1, a rotating shaft 441 rotatably connected between the vertical arms 442, and a rotating swing frame 41 fixedly connected to the rotating shaft 441 (the shape of the rotating swing frame 41 is: the rotating swing frame 41 includes swing rod portions spaced apart on both sides, and the inner ends of the swing rod portions are fixedly connected to the rotating shaft 441), and the rotating swing frame 41 is hinged to a hanging arm 42 (the hinge method is: the outer end of the swing rod portion is integrally formed with a vertical portion vertically arranged inward, and a hinge shaft is rotatably connected between the vertical portions, and the hanging arm 42 is fixedly connected to the hinge shaft), and the lower end of the hanging arm 42 is hinged to a long sampling tube 43. The specific hinge method is: the bottom of the hanging arm 42 is fixedly connected to a U-shaped hinge seat 421, and the two ends of the long sampling tube 43 are respectively fixedly connected to pins hinged on the U-shaped hinge seat 421.

[0044] At the same time, a driving motor 44 that drives the rotating shaft 441 is fixedly assembled on the climbing frame 1; specifically, the output shaft of the driving motor 44 is fixedly installed on the rotating shaft 441 in the same manner as in the existing method, such as by a coupling.

[0045] At the same time, a motor bracket 442 for mounting the driving motor 44 is fixedly connected to the outer wall of the climbing frame 1.

[0046] During operation, when the entire device moves in a circle on the pool mouth of the concentration tank through the rolling and crawling mechanism, after moving to a certain distance, at this time, under the drive of the drive motor 44 (the drive motor 44 is a forward and reverse motor disclosed in the prior art), the rotating swing frame 41 flips downward until the sampling long tube 43 descends. Since the sampling long tube 43 is arranged in a hinged manner, the sampling long tube 43 remains in a vertical state.

[0047] When the sampling tube 43 is turned over and immersed in the clear water layer, the sample is taken. In this way, the clear water layer can be sampled in a flexible and efficient manner.

[0048] At the same time, the sampling point is controlled by the length of the crawling track of the rolling crawling mechanism. Therefore, in the actual production process, samples can be taken at most positions in the concentration tank, thereby accurately reflecting the concentration process of the concentration tank through the condition of the clear water layer.

[0049] Example 2

[0050] like Figure 1-5As shown, in this embodiment, based on the structure of embodiment 1, a plurality of sampling holes 431 spaced apart from each other are provided on the long sampling tube 43 ; during the sampling process, water from the clear water layer enters through the sampling holes 431 .

[0051] In order to achieve sampling at different depths of the clear water layer, a number of baffles 432 are fixedly connected to the above-mentioned sampling long tube 43. The baffles 432 are annular and are respectively located below the sampling holes 431. Therefore, a sample storage cavity is formed between the sampling hole 431 at the upper position and the baffle 432 at the lower position. Since the sample storage cavity is located at different heights, after the rotating swing frame 41 is flipped, the flip angle is controlled to determine the degree of descent of the sampling long tube 43. Therefore, if the sampling depth is shallow, the flip angle is small, and if the depth is large, the flip angle is large.

[0052] Example 3

[0053] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, both sides of the climbing frame 1 are fixedly assembled and connected with a crawling component that rolls against the inner and outer walls of the concentration tank, and the crawling component includes a rotary turning motor 21 fixedly installed at the bottom position of the climbing frame 1 (specifically, the bottom of the climbing frame 1 is fixedly connected with a bottom motor seat 212, and the rotary turning motor 21 is fixedly installed on the bottom motor seat 212 through a plurality of connecting screws), and the output shaft of the rotary turning motor 21 is fixedly assembled and connected with a resisting arm 22 (the longitudinal cross-section of the resisting arm 22 is L-shaped).

[0054] The above-mentioned arm 22 is rotatably connected to a roller 24 that abuts against the side wall of the concentration tank. A motor that drives the roller 24 to rotate is installed at the bottom of the arm 22 (same as the existing method, a motor bracket is fixedly installed at the bottom of the arm 22, and the motor is fixedly installed in the motor bracket).

[0055] At the same time, the bottom of the climbing frame 1 is fixedly connected with a fixed arm 211; the output shaft of the rotary turning motor 21 is rotatably connected to the fixed arm 211. Specifically, the fixed arm 211 is installed with an adapted bearing in the same manner as in the prior art.

[0056] The top of the arm 22 is fixedly connected to a fixing seat (the transverse cross-section of the fixing seat is circular), and the output shaft of the rotary turning motor 21 is fixedly connected to the fixing seat.

[0057] During operation, the rollers 24 on either side press against the inner and outer walls of the concentrator tank. The friction between the rollers 24 and the tank creates a circular motion. Similar to existing circular motion methods, this motion is achieved by adjusting the direction of movement through continuous rotation. Specifically, the angle of the crawling assembly is adjusted by rotating the turning motor 21 to achieve circular motion around the concentrator tank.

[0058] At the same time, in order to reduce the resistance of circumferential motion, the central part of the above-mentioned climbing frame 1 is rotatably connected to a supporting wheel; the supporting wheel includes a rotating shaft 441 rotatably connected to the climbing frame 1, and the bottom of the rotating shaft 441 is fixedly connected to a wheel frame 3, and the wheel frame 3 is rotatably connected to a roller 31.

[0059] During operation, when in circumferential motion, the support wheel is supported on the top of the pool mouth of the concentration tank, and during the support rolling process, the rotating shaft 441 continuously rotates to adjust the direction and rotates synchronously with the circumferentially moving crawling component.

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
