Description

Technical Field

[0001] The utility model relates to the technical field of pulp detection, and specifically relates to a pulp detection device. Background Art

[0002] When measuring pulp, the flow-through method is adopted. This method can play an effective guiding role in the flotation production process of non-ferrous metals with relatively high grades. However, for the magnetic separation production process of iron ore and the flotation production operation points with relatively low contents of measured elements, the pulp is a suspension. During the flow-through measurement process, the pulp is generally in a non-uniform state. When using X-ray fluorescence analysis technology, the effective measurement depth of X-ray fluorescence analysis technology is only about 1 mm. Therefore, the actually measured pulp cannot fully represent the flowing pulp, and the measurement result has a large error, making it impossible to guide production. Content of the Utility Model

[0003] In view of the deficiencies of the prior art, the utility model provides a pulp detection device, which solves the problem that the depth of the pulp in the flow-through measurement cannot adapt to the measurement depth of the X-ray fluorescence analysis technology, resulting in a large measurement error.

[0004] To achieve the above object, the utility model provides the following technical solution: A pulp detection device includes a chassis. A detection piece for pulp detection is slidably installed on the chassis. A detection bin for carrying the pulp to be detected is installed on the chassis. An sampling component for promoting the formation of a detection layer on the surface layer of the detection bin is arranged in the detection bin.

[0005] The sampling component includes a central shaft installed in the detection bin and rotating circumferentially. Sampling plates are symmetrically installed above and below the central shaft, and the sampling plates rotate synchronously with the central shaft.

[0006] The detection bin includes a bearing cylinder and a sampling cylinder installed at the upper end of the bearing cylinder. A feed pipe for overflowing the pulp inward is arranged on the sampling cylinder. A collecting eaves plate for collecting the pulp onto the sampling plate is installed at the connection position between the bearing cylinder and the sampling cylinder.

[0007] In one embodiment, the sampling plate includes a sleeve installed on the central shaft and a plate body placed at the upper end of the sleeve. A telescopic rod placed in the sleeve is connected to the lower end of the plate body.

[0008] The upper end face diameter of the collecting eaves plate is larger than the lower end face diameter. The lower end face diameter of the collecting eaves plate is smaller than the plate body diameter, and the plate body diameter is not larger than the barrel mouth diameter of the sampling cylinder.

[0009] In one embodiment, a mixing sleeve is connected between the casing and the central shaft. The mixing sleeve is conical and its diameter gradually increases in the extending direction of the plate body. It is hollow inside, and a number of overflow holes for reducing the particle binding degree in the pulp are opened thereon. The opening diameters of the overflow holes at different positions are proportional to the diameter of the mixing sleeve.

[0010] In one embodiment, a discharge pipe is installed at a position symmetric to the center of the feed pipe in the detection bin. The bottom plate of the detection bin is inclined, and the installation position of the discharge pipe is at the lowest point of the detection bin.

[0011] In one embodiment, the central shaft penetrates through the detection bin and extends outwards, and a driving motor for driving the central shaft to rotate is connected to the side wall of the chassis.

[0012] In one embodiment, the detection member includes a transmitting end and a receiving end.

[0013] Compared with the prior art, the present utility model provides a pulp detection device, which has the following beneficial effects:

[0014] In the technical solution disclosed by the present utility model, before the pulp to be detected is mixed into a whole in the detection bin, a sample presenting assembly is set to separate the pulp entering the detection bin, so that it is dispersed in batches under the detection member. By sliding the detection member on the chassis, the detection surface covers the entire sample presenting assembly, and thus covers the particles presented on the sample presenting assembly. Thereby, the depth of the flowing pulp is reduced to adapt to the detection depth of the X-ray fluorescence analysis technology, and the detection error is reduced.

[0015] By connecting a mixing sleeve between the casing and the central shaft in the present utility model, and opening overflow holes with different diameters according to the diameter change of the mixing sleeve, thus, when the central shaft rotates, the mixing sleeve rotates in the detection bin accordingly, stirring and mixing the pulp already in the detection bin, and reducing the adverse effect of sedimentation on the discharge of the pulp.

Specific embodiments

[0022] The following will be combined with the drawings and embodiments to detail the implementation manner of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0024] The specific problem targeted by this specific embodiment is as follows: When measuring pulp, the flow-through method is adopted. This method can play an effective guiding role in the flotation production process of non-ferrous metals with relatively high grades, but for the magnetic separation production process of iron ore and the flotation production operations with relatively low contents of measured elements, the pulp is a suspension. In the process of flow-through measurement, the pulp is generally in a non-uniform state. When using X-ray fluorescence analysis technology, the effective measurement depth of X-ray fluorescence analysis technology is only about 1 mm. Therefore, the actually measured pulp cannot fully represent the flowing pulp, and the measurement result has a large error and cannot guide production. Based on the above problems, this solution describes a pulp detection device. Before the pulp to be detected is mixed into a whole in the detection bin 3, a sample presenting component 4 is set to separate the pulp entering the detection bin 3, so that it is dispersed in batches under the detection component 2. By sliding the detection component 2 on the chassis 1, the detection surface covers the entire sample presenting component 4, and then covers the particles presented on the sample presenting component 4. Thus, the depth of the flow-through pulp is reduced to make it adapt to the detection depth of X-ray fluorescence analysis technology and reduce the detection error.

[0025] Such as Figures 1 - 4As shown in the figure, a pulp detection device includes a chassis 1. A detection member 2 for pulp detection is slidably installed on the chassis 1. A detection bin 3 for carrying the pulp to be detected is installed on the chassis 1. An sample-forming assembly 4 for promoting the formation of a detection layer on the surface layer of the detection bin 3 is arranged in the detection bin 3. The sample-forming assembly 4 includes a central shaft 41 installed in the detection bin 3 and rotating circumferentially. The central shaft 41 extends out through the detection bin 3 and is connected to a driving motor for driving the central shaft 41 to rotate on the side wall of the chassis 1. Driven by the driving motor, the central shaft 41 will have a tendency of self-rotation. Sample plates 42 are symmetrically installed above and below the central shaft 41, and the sample plates 42 rotate synchronously with the central shaft 41. The sample plate 42 includes a sleeve 421 installed on the central shaft 41 and a plate body 422 placed at the upper end of the sleeve 421. The inside of the sleeve 421 is hollow. A telescopic rod 423 placed inside the sleeve 421 is connected to the lower end of the plate body 422. When the central shaft 41 rotates 90 degrees in the initial state, the plate body 422 is in a position directly facing the transmitting end 21. The free end of the telescopic rod 423 is driven to extend, so that the plate body 422 contacts the collecting eaves plate, thus forming a state of receiving pulp. The advantage of having the sleeve 421 outside the telescopic rod 423 is to prevent the particles in the pulp from contacting the free end of the telescopic rod 423 and causing blockage after the free end contracts.

[0026] The detection bin 3 includes a bearing cylinder 31 and a sampling cylinder 32 installed at the upper end of the bearing cylinder 31. A feed pipe 33 for overflowing pulp inward is arranged on the sampling cylinder 32. A collecting eaves plate for collecting pulp onto the sample plate 42 is installed at the connection position between the bearing cylinder 31 and the sampling cylinder 32. The upper end face diameter of the collecting eaves plate is larger than the lower end face diameter. The lower end face diameter of the collecting eaves plate is smaller than the diameter of the plate body 422. The diameter of the plate body 422 is not larger than the diameter of the opening of the sampling cylinder 32. Under the action of the collecting eaves plate, the ray area emitted by the transmitting end 21 during movement can cover the collecting range of the pulp, thereby enhancing the comprehensiveness of detection.

[0027] A discharge pipe 35 is installed at a position that is centrosymmetric with the feeding pipe 33 in the detection bin 3. The bottom plate of the bearing cylinder 31 is inclined, and the installation position of the discharge pipe 35 is at the lowest point of the bearing cylinder 31. In order to better discharge the pulp in the bearing cylinder 31, a mixing sleeve 43 is connected between the sleeve 421 and the central shaft 41. The mixing sleeve 43 is conical and its diameter gradually increases in the extending direction of the plate body 422. It is hollow inside, and a number of overflow holes 44 for reducing the particle binding degree in the pulp are opened on it. The opening diameters of the overflow holes 44 at different positions are proportional to the diameter of the mixing sleeve 43, so as to act on particles of different diameters and increase the movement of the particles under the action of the mixing sleeve 43. By connecting the mixing sleeve 43 between the sleeve 421 and the central shaft 41 in the present utility model and providing overflow holes 44 with different diameters according to the diameter change of the mixing sleeve 43, when the central shaft 41 rotates, the mixing sleeve 43 can rotate in the detection bin 3, stir the pulp already in the bearing cylinder 31, and reduce the adverse effect of sedimentation on the discharge of the pulp.

[0028] The detection member 2 includes a transmitting end 21 and a receiving end 22. The transmitting end 21 faces the plate body 422. After the feeding pipe 33 completes one feeding, the transmitting end 21 emits rays including but not limited to X-rays, γ-rays, infrared rays, and lasers to the plate body 422. The detected light is reflected by the pulp and received by the receiving end 22, so that the pulp can be detected. Based on the X-ray fluorescence analysis technology, the effective measurement depth is only about 1 mm. Therefore, at the beginning of the pre-detection, practical tests should be carried out according to the diameter of the feeding pipe 33, including but not limited to the time required to form a 1-mm pulp layer on the plate body 422. After completing the pre-experiment, in the actual detection, that is, the connection time of the feeding pipe 33 is controlled according to the calculated time.

[0029] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model mainly protects mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0030] It should be noted that in this article, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0031] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
