Description

Technical Field

This method mainly uses ferrosilicon as a reducing agent to reduce magnesium from its compounds under high temperature conditions. During the Pidgeon magnesium refining process, the discharged magnesium slag is mainly composed of silicon dioxide and incompletely reacted magnesium oxide. In order to accurately analyze the content of magnesium oxide in the magnesium slag, scientific and reasonable sampling and analysis are required.

[0003] At present, in the sampling process of magnesium slag in the Pijiang process of magnesium refining, it is necessary to make safety preparations first, wear appropriate personal protective equipment to prevent high temperature injuries, and prepare the necessary sampling tools, such as stainless steel shovels, sampling long-handled spoons, sealed containers, etc.; when sampling, it is necessary to carefully collect an appropriate amount of magnesium slag samples and put them into the storage container prepared in advance; however, the temperature of the magnesium slag when it is discharged is about 1200°C, and the optimal temperature for sampling is lower than 100°C but higher than the ambient temperature. Wearing personal protective equipment cannot completely avoid the safety hazard of burns; the scope and area of ​​manual collection are limited, and the samples collected at a single time are not representative, and the diversity of the samples cannot be ensured.

The interior of the sampling box 813 is provided with a plurality of slots from top to bottom that are horizontally oriented and connected to the sampling chamber 814. The interior of the sampling box 813 is also provided with an auxiliary guide slot located above the topmost slot. The plurality of slots inside the sampling box 813 are all connected to the blocking piece 821 by spring sliding. The side wall of the sampling box 813 is provided with a slide rail 3 822. The slide rail 3 822 is horizontally connected to a protective cover 823 by an electric slider. The protective cover 823 is connected to the sampling box The auxiliary guide groove inside the sampling box 813 is slidably connected; the outer wall of the side of the protective cover 823 close to the blocking piece 821 is provided with a reset outlet 824 adapted to the blocking piece 821, and the multiple reset outlets 824 are connected with an adjustment plate 825 in a common upward and downward sliding manner. The adjustment plate 825 is connected to the slide rail 826 opened on the side wall of the sampling box 813 through an electric slider for upward and downward sliding.

It should be noted that the electric slider is a long strip structure and is provided with a slide groove 827 (such as Fig.11 As shown), so that the adjustment plate 825 can slide horizontally thereon.

[0043] When in use, the support seat 1 is placed at a certain distance from the magnesium slag discharge position. The personnel can stay away from the magnesium slag discharge port during operation. The sampling process is contactless operation, which effectively prevents personnel from being scalded. The output end of the motor 2 is rotated to drive the hydraulic rod 3 and the telescopic bracket 4 to rotate and move. The telescopic end of the telescopic bracket 4 is extended, and the telescopic connecting rod 2 6 is adaptively extended and tilted. The telescopic bracket 4 drives the position adjustment mechanism 7 and the depth adjustment mechanism 8 to approach the magnesium slag discharge port, and sampling is performed when the magnesium slag is just discharged.

[0044] The rotation of motor 2 721 drives gear 1 722 and gear 2 723 to rotate, and gear 2 723 drives adjusting member 724 to rotate on adjusting disk 713. When adjusting member 724 rotates, the pushing member of adjusting member 724 pushes the corresponding fitting member 811 and sliding member 812 to slide on slide rail 2 714, and sliding member 812 drives sampling box 813 to change position, so as to synchronously change the positions of multiple sampling boxes 813 before sampling, expand the sampling area and range, and perform multi-point sampling with multiple sampling boxes 813 to ensure the diversity of samples and prevent sampling result deviation caused by uneven distribution of magnesium slag.

[0045] During sampling, the top wall of the output end of the hydraulic rod 3 moves downward, driving the telescopic bracket 4 and the position adjustment mechanism 7 and the depth adjustment mechanism 8 to move downward. The sampling box 813 moves downward and is inserted into the magnesium slag discharge pile for sampling. The magnesium slag enters the sampling bin 814. The electric slider drives the protective cover 823 to move horizontally on the slide rail 3 822, driving the blocking piece 821 to move toward the sampling bin 814. The blocking piece 821 is inserted into the magnesium slag inside the sampling bin 814, and the magnesium slag in the sampling bin 814 is evenly divided into three parts. During this process, the adjustment plate 825 moves synchronously with the protective cover 823, and slides horizontally relative to the slide groove 827 on the corresponding electric slider, that is, the corresponding electric slider is still located on the slide rail 4 826, so as to drive the adjustment plate 825 to move upward afterwards.

[0046] After sampling is completed, the output end of the hydraulic rod 3 moves upward to drive the telescopic bracket 4 and the position adjustment mechanism 7 and the depth adjustment mechanism 8 to move upward, and the magnesium slag and the sampling box 813 move upward together, and the hydraulic rod 3 and the telescopic bracket 4 are driven by the motor 2 to rotate to the top of the sampling mixing mechanism 9.

[0047] Reference Figure 1 and Fig. 9 The sampling and mixing mechanism 9 includes a sample selection component 91 and a mixing component 92. The sample selection component 91 includes a slide rail 5 911. The top wall of the support seat 1 is symmetrically provided with slide rails 5 911. The slide rails 5 911 are connected to a sample selection plate 912 by an electric slider for sliding back and forth. The sample selection plate 912 is rotationally connected to the electric slider.

[0048] Reference Figures 9 and 10 The mixing assembly 92 includes a cross piece 921, a cross piece 921 is fixedly connected to the middle of the bottom wall of the adjusting disk 713, a mixing bucket 925 is fixedly connected to the bottom wall of the support seat 1, and the inner wall of the mixing bucket 925 is rotatably connected to an alignment piece 922 through a support plate 923. The top wall of the support plate 923 is inclined from the middle to both sides, and a hole position matching the cross piece 921 is opened on the top wall of the alignment piece 922. The upper end of the hole position and the lower end of the cross piece 921 are chamfered so that the cross piece 921 can be inserted into the hole position after the two are aligned. A plurality of inclined mixing plates 924 arranged inside the mixing bucket 925 are fixed along the circumferential direction at the bottom of the alignment piece 922.

[0049] According to the sampling needs, the electric slider on the slide rail 4 826 drives the adjustment plate 825 to move upward. When the adjustment plate 825 moves upward, it gradually changes from an overlapping state to a separated state with the protective cover 823. The blockage of the multiple reset outlets 824 by the adjustment plate 825 is also released from bottom to top. The spring (not shown in the figure) connected between the blocking plate 821 and the sampling box 813 drives the blocking plate 821 to reset and leave the sampling chamber 814.

[0050] During sampling, the sample selection plate 912 is horizontally blocked above the mixing bucket 925, and the sample selection plate 912 catches the magnesium slag waste sample falling from the sampling bin 814. After the sampling is completed, the slide rail 5 911 drives the sample selection plate 912 to move backward, and the rear end of the sample selection plate 912 gradually leaves the top of the support seat 1 and loses support. Under the action of gravity, the sample selection plate 912 changes from a horizontal state to a state inclined backward and downward, thereby unloading the magnesium slag waste sample, and the sample left in the sampling bin 814 is finally released and falls into the mixing bucket 925.

[0051] The magnesium slag in the sampling bin 814 is divided into upper, middle and lower parts by the blocking plate 821, and the magnesium slag in the upper, middle and lower parts is in the sampling position from shallow to deep; when it is necessary to detect the magnesium slag in the shallow part, the adjusting plate 825 releases the blockage of the blocking plates 821 in turn on the lower and middle layers, and after the magnesium slag in the lower and middle layers falls onto the sample selection plate 912 and is unloaded, the adjusting plate 825 continues to release the blockage of the upper layer of the blocking plate 821, so that the magnesium slag in the shallow part falls into the mixing bucket 925.

[0052] When the magnesium slag in the middle needs to be tested, the adjusting plate 825 releases the blockage of the blocking plate 821 in the lower layer. After the magnesium slag in the lower layer falls to the sample selection plate 912 and is unloaded, the adjusting plate 825 continues to release the blockage of the blocking plate 821 in the middle layer, so that the magnesium slag in the middle layer falls into the mixing bucket 925.

[0053] When it is necessary to detect the magnesium slag at a deep level, when the sample selection plate 912 is in an inclined state, the blockage of the blocking plate 821 at the lower layer is directly released through the adjustment plate 825, so that the magnesium slag at the lower layer falls into the mixing bucket 925.

[0054] Reference Figures 3 to 5 and Fig.10 After the sampling is completed, the sealed can or sealed bag for collecting and storing the samples is placed under the outlet of the mixing bucket 925, and the hydraulic rod 3 drives the cross piece 921 to move down and engage into the alignment piece 922. When the magnesium slag falls, the motor 2 721 continues to rotate, so that the protrusion 725 fits with the force-bearing piece on the fixing piece 715, and then the fixing piece 715 can be pushed by the protrusion 725, and the fixing piece 715 drives the adjusting disk 713 to rotate, and the adjusting disk 713 drives the stabilizing rod 712 to slide on the bottom wall of the annular slide rail 1 711 to maintain the balance and stability of the adjusting disk 713 when it rotates.

[0055] When the adjusting disk 713 rotates, it drives the depth adjusting mechanism 8 to rotate and sample, so as to facilitate the dispersion and mixing of magnesium slag sampled from multiple places. At the same time, the adjusting disk 713 drives the cross piece 921 to rotate, and the alignment piece 922 and the inclined mixing plate 924 rotate accordingly. In the mixing bucket 925, the rotating inclined mixing plate 924 further stirs and mixes the rotating and falling magnesium slag. Sufficient mixing is beneficial to improving the representativeness of the sample.

[0056] The mixed sample falls into a sealed can or bag below, is sealed, and sent to the laboratory for analysis as soon as possible.

[0057] The present invention also provides a method for analyzing and sampling the magnesium oxide content in magnesium slag by the Pidgeon process, which is completed by using the above-mentioned sampling device for analyzing the magnesium oxide content in magnesium slag by the Pidgeon process. The specific processing method includes the following steps: S1. Preparation work: Place the sampling device in a suitable position, and the staff prepares personal protective equipment and pre-cleaned and dried containers for storing samples.

[0058] S2. Determine the sampling time and position: Sampling is performed when the temperature of the magnesium slag just begins to drop after being discharged, and the sampling position is adjusted by the cooperation of the hydraulic rod 3, the telescopic bracket 4 and the position adjustment mechanism 7.
