A sample drying device for raw ore sample analysis

Abstract

This invention provides a sample drying device for raw ore sample analysis. The device includes a body with a heating tube fixedly connected to its inner wall and a turning assembly inside the body. In this device, the sample box rotates with the clamping frame, causing the sample to continuously change angles in space. This allows hot air to contact the sample surface from different directions, increasing the rate of moisture evaporation. Compared to static heating, this method better avoids localized moisture retention and improves drying uniformity. A turning plate moves the raw ore sample within the sample box, continuously loosening and turning the sample, constantly mixing the internal and external samples, significantly reducing the risks of agglomeration, sintering, and coking. Because the turning direction is perpendicular to the main rotation direction, the raw ore sample moves synchronously in both directions, resulting in more uniform drying and more comprehensive penetration of hot air into the sample.

Description

Technical Field

[0001] This utility model relates to the field of sample drying technology, specifically a sample drying device for raw ore sample analysis. Background Technology

[0002] Raw ore analysis refers to the application of various mineralogical principles and methods to observe and analyze rock and mineral samples, including slides, sand sections, fragments, and powders, based on their optical, electrical, acoustic, thermal, magnetic, weight, hardness, odor, and main chemical composition characteristics, in order to distinguish their mineral categories and study the main mineral composition, mineral formation sequence, structure, texture, and ore type of rocks and ores. Before rock and mineral analysis and testing, the samples need to be dried, which requires the use of drying equipment.

[0003] However, in actual drying processes, ore samples are usually placed in sample storage bottles and then dried by heating devices. This drying method cannot quickly dry small rock and mineral samples with a large number of samples. Therefore, we propose a sample drying device for raw ore sample analysis. Utility Model Content

[0004] The purpose of this invention is to provide a sample drying device for the analysis of raw ore samples, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample drying device for raw ore sample analysis, comprising a body, a heating tube fixedly connected to the inner wall of the body, and a turning assembly disposed inside the body, the turning assembly comprising: A servo motor, wherein the output end of the servo motor is connected to a rotating shaft, and a clamping frame is fixedly connected to the end face of the rotating shaft; A placement box, the top of which is rotatably connected to a rotating rod, the side wall of which is fixedly connected to a toggle plate, and the top of which is fixedly connected to a gear; A toothed ring, which is fixedly connected to the inner wall of the machine body.

[0006] Preferably, the side wall of the machine body is provided with ventilation holes, and the front of the machine body is hinged with a door, and the ventilation holes allow air containing moisture to be discharged.

[0007] Preferably, the servo motor is fixedly connected to the outer wall of the machine body, and the cross-section of the clamping frame is arranged in a U-shape.

[0008] Preferably, there are two sets of placement boxes, which are symmetrically arranged. The placement boxes are slidably connected to the inner wall of the clamping frame, and small raw ore samples are placed in the two sets of placement boxes.

[0009] Preferably, the gear ring meshes with the gear, and the actuating plate is located inside the two sets of clamping frames.

[0010] Preferably, the clamping frame is slidably connected to the limiting rod, the limiting rod is inserted into the insertion rod, and a spring is fixedly connected to the end face of the insertion rod, with the end of the spring away from the insertion rod abutting against the inner wall of the limiting rod.

[0011] Preferably, the side wall of the clamping frame has a limiting hole, which is inserted into the insertion rod.

[0012] Compared with the prior art, this utility model provides a sample drying device for raw ore sample analysis, which has the following beneficial effects: 1. This raw ore sample drying device, through its set-on flipping component, allows the placement box to flip along with the clamping frame, causing the sample to continuously change angles in space. At this time, hot air can contact the sample surface from different directions, increasing the rate of moisture evaporation. Compared with static heating, it can better avoid localized humidity retention and improve drying uniformity. The agitator plate moves the raw ore sample located in the placement box, achieving continuous loosening and flipping of the sample. The internal and external samples are constantly mixed, greatly reducing the risks of agglomeration, sintering, and coking. Since the agitator direction is perpendicular to the main rotation direction, the raw ore sample moves synchronously in two directions, resulting in more uniform drying and allowing hot air to penetrate the sample more comprehensively.

[0013] 2. The sample drying device for raw ore sample analysis uses a limit rod to automatically lock the pin, preventing the placement box from loosening due to inertia or vibration during rotation and flipping, ensuring that the position of the raw ore sample remains unchanged, and avoiding uncontrolled flipping or uneven drying.

[0016] As shown Figures 1-5 in the figure, the utility model provides a technical solution: a sample drying device for analyzing raw ore samples, which includes a machine body 1. A heating pipe 2 is fixedly connected to the inner wall of the machine body 1. A turning component 4 is arranged inside the machine body 1. The turning component 4 includes a servo motor 401, a rotating shaft 402, a clamping frame 403, a placement box 404, a rotating rod 405, a拨动 plate 406, a gear 407, and a toothed ring 408.

[0017] In an embodiment of the present utility model, the servo motor 401 is fixedly connected to the outer wall of the machine body 1. The output end of the servo motor 401 is connected to a rotating shaft 402. The end face of the rotating shaft 402 is fixedly connected to a clamping frame 403. The cross-section of the clamping frame 403 is arranged in a U shape.

[0018] The number of placement boxes 404 is set to two groups. The two groups of placement boxes 404 are symmetrically arranged. The placement box 404 is slidably connected to the inner wall of the clamping frame 403. The top of the placement box 404 is rotatably connected to a rotating rod 405. A拨动 plate 406 is fixedly connected to the side wall of the rotating rod 405. A gear 407 is fixedly connected to the top end of the rotating rod 405. Small raw ore samples are placed inside the two groups of placement boxes 404.

[0019] The toothed ring 408 is fixedly connected to the inner wall of the machine body 1. The toothed ring 408 is meshed with the gear 407. The拨动 plate 406 is located inside the two groups of clamping frames 403.

[0020] An air exchange hole 3 is opened on the side wall of the machine body 1. A door body is hinged to the front of the machine body 1. The air exchange hole 3 enables the air with water vapor to be discharged.

[0021] Place small raw ore samples inside the two groups of placement boxes 404, and then insert the placement boxes 404 into the clamping frames 403. The servo motor 401 drives the rotating shaft 402 to rotate. The rotating shaft 402 drives the clamping frame 403 and the placement box 404 to rotate. The heating pipe 2 heats the air inside the machine body 1. The placement box 404 flips with the clamping frame 403, so that the samples continuously change angles in space. At this time, hot air can contact the surface of the samples from different directions, improving the water evaporation rate. Compared with static heating, it can more effectively avoid local humidity retention and improve drying uniformity.

[0022] When the placement box 404 is inserted into the clamping frame 403, the gear ring 408 meshes with the gear 407. As the placement box 404 rotates, the rotating rod 405 also rotates along the axis of the rotating shaft 402. The gear 407 is displaced along the gear ring 408, which further causes the gear 407, the rotating rod 405, and the agitator plate 406 to rotate along the axis of the rotating rod 405. The agitator plate 406 is arc-shaped and agitates the raw ore sample located in the placement box 404, so as to continuously loosen and turn the sample, and continuously mix the internal and external samples, which greatly reduces the risk of agglomeration, sintering, coking, etc. Since the agitation direction is perpendicular to the main rotation direction, the raw ore sample moves synchronously in two directions, the drying is more uniform, and the hot air can penetrate the sample more thoroughly.

[0023] In addition, the clamping frame 403 is slidably connected to the limiting rod 6, the limiting rod 6 is inserted into the insertion rod 7, and a spring 8 is fixedly connected to the end face of the insertion rod 7. The end of the spring 8 away from the insertion rod 7 abuts against the inner wall of the limiting rod 6. A limiting hole 5 is opened on the side wall of the clamping frame 403, and the limiting hole 5 is inserted into the insertion rod 7. After the placement box 404 is inserted, the limiting rod 6 is slidably connected to the clamping frame 403. Under the elastic action of the spring 8, the insertion rod 7 is inserted into the limiting hole 5 to realize automatic pin locking, preventing the placement box 404 from loosening due to inertia or vibration during rotation and flipping, ensuring that the position of the raw ore sample remains unchanged, and avoiding uncontrolled flipping or uneven drying.

[0024] In this invention, during use, the placement box 404 is inserted into the clamping frame 403. The servo motor 401 drives the rotating shaft 402 to rotate, which in turn drives the clamping frame 403 and the placement box 404 to rotate. The heating tube 2 heats the air inside the machine body 1. The placement box 404 rotates with the clamping frame 403, causing the sample to continuously change angles in space. Hot air can contact the sample surface from different directions. While the placement box 404 rotates, the rotating rod 405 also rotates along the axis of the rotating shaft 402. The gear 407 is displaced along the gear ring 408, which further causes the gear 407, the rotating rod 405, and the actuating plate 406 to rotate along the axis of the rotating rod 405. The actuating plate 406 actuates the raw ore sample located in the placement box 404, thereby continuously loosening and turning the sample, and continuously mixing the internal and external samples.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
