Description

TECHNICAL FIELD

[0001] The utility model relates to graphite purity test technical field, specifically a graphite purity testing device. BACKGROUND

[0002] Graphite is a mineral produced in metamorphic rocks, which is formed by coal or carbonaceous rocks or sediments subjected to regional metamorphism or magmatic intrusion. However, the purity detection of graphite is mainly to detect the carbon content. Generally, after the graphite is burned at high temperature, the residual material obtained by completely escaping the graphite and volatile material is ash, and the ratio of the residual material to the original mass of the graphite is used to calculate the ash content.

[0003] For example, the patent number CN211784934U discloses a graphite purity testing device. The device drives two crushing rollers with intermeshing teeth to crush the graphite blocks added in the opening and drop them into the arc-shaped combustion groove. The graphite is completely burned by cooperating with the burner to improve the accuracy of the test results.

[0004] However, the device in the above-mentioned patent can only crush and burn the graphite material, but cannot control the quantitative dropping of the graphite powder after crushing. If the graphite material is crushed after being weighed in advance, it is easy to cause the graphite powder to scatter during the crushing process, and the weight of the scattered graphite powder is different from the data weighed in advance, which can affect the subsequent combustion detection data of the graphite powder. Therefore, we provide a graphite purity testing device to solve the above problems. UTILITY MODEL CONTENT

[0027] Referring to Figure 1 - Figure 7The embodiment provides a graphite purity testing device, which comprises a box body 1, the inside of the box body 1 is sequentially provided with a crushing mechanism 2, a quantitative discharging mechanism 3 and a detection mechanism 4 from top to bottom, and the crushing mechanism 2 comprises crushing rollers 202 used for crushing graphite materials.

[0028] With reference to Figures 1 to 7 The crushing mechanism 2 can facilitate the crushing treatment of the graphite materials, the crushing rollers 202 are connected with external driving devices, the two crushing rollers 202 rotate in opposite directions, and the graphite materials are crushed.

[0029] The crushing mechanism 2 further comprises protection blocks 201 fixed to the inner wall of the box body 1 and located on both sides of the crushing rollers 202, two inclined plates 203 fixed to the inner wall of the box body 1 and located above the crushing rollers 202, and a discharging frame 204 fixedly connected with the two protection blocks 201 and located below the crushing rollers 202.

[0030] The crushing mechanism 2 is connected with external driving devices, the crushing rollers 202 can crush the graphite raw materials, the graphite materials are guided to enter the two crushing rollers 202 for crushing through the inclined plates 203 when the graphite materials are crushed, and the graphite materials crushed and falling everywhere can be prevented through the protection blocks 201.

[0031] The quantitative discharging mechanism 3 comprises a storage frame 301 located below the crushing rollers 202, a quantitative assembly and a vibration assembly connected with the storage frame 301, and a driving assembly connected with the quantitative assembly, and the detection mechanism 4 comprises a combustion frame 403 located below the storage frame 301.

[0032] With reference to Figures 1 to 7 The quantitative discharging mechanism 3 can facilitate the quantitative weighing of the crushed graphite powder, and the weighed graphite powder is discharged in batches through the quantitative assembly, so that the graphite powder can be prevented from being blocked and the weight of the graphite powder falling into the detection mechanism 4 can be controlled.

[0033] The quantitative discharging mechanism 3 further comprises a connecting plate 302 fixed to the outer surface of the storage frame 301 and a weight sensor 303 connected with the connecting plate 302 and installed on the inner wall of the box body 1.

[0036] By arranging the quantitative assembly, the crushed graphite material can be weighed conveniently, and by arranging the discharging roller 304, the weighed graphite powder can be discharged quantitatively, so that the weight of the graphite powder falling can be controlled conveniently, and the situation that the combustion detection data is different after the graphite powder falls into the detection mechanism 4 is avoided.

[0038] As a supplement, when a small amount of graphite material is detected for purity, there is a difference between the weight of the graphite material before crushing and the actual weighing data of the graphite powder by the weight sensor 303, so the total weight of the graphite powder is weighed out.

[0039] Then the graphite powder is sequentially dropped by the batch discharging roller 304 in the quantitative assembly, and the weight of the graphite powder dropped into the detection mechanism 4 can be calculated by the number of drops through the weight of the single drop of the discharging roller 304. The batch weight is calculated as the storage capacity of the groove in the discharging roller 304. If the weight of the graphite material purity detection is not considered, all the graphite powder is discharged into the detection mechanism 4 through the discharging roller 304.

[0044] The linkage assembly further comprises a pressing plate 3014 rotationally matched with the outer surface of the storage frame 301 and in contact with the arc-shaped transmission block 3012, a first sprocket 3015 fixed to the outer surface of the pressing plate 3014, a second sprocket 3016 fixed to the outer end of the discharge roller 304, and a chain 3017 engaged with the second sprocket 3016 and the first sprocket 3015.

[0045] The linkage assembly can facilitate linkage between the knocking assembly and the quantitative assembly, so that the quantitative assembly and the knocking assembly move and close at the same time.

[0046] When the discharge roller 304 is driven to rotate by the driving assembly, the discharge roller 304 can drive the pressing plate 3014 to extrude and push the arc-shaped transmission blocks 3012 on both sides through the second sprocket 3016, the chain 3017 and the first sprocket 3015, so that the arc-shaped transmission blocks 3012 move through the spring telescopic rod 3010, and then the spring telescopic rod 3010 drives the knocking plate 308 to knock and vibrate the storage frame 301 through the transmission plate 3013.

[0047] The driving assembly comprises a double-output-shaft motor 306 installed on the outer surface of the storage frame 301, and a driving gear 307 fixedly connected with the output rotating shaft of the double-output-shaft motor 306 and engaged with the driven gear 305.

[0048] The driving assembly can facilitate rotation of the discharge roller 304, and the double-output-shaft motor 306 is provided with a PLC programmable logic controller, so that the double-output-shaft motor 306 is in data communication with the weight sensor 303.

[0049] Through the start of the double-output-shaft motor 306, the double-output-shaft motor 306 can drive the discharge roller 304 to rotate in the storage frame 301 through the engagement of the driving gear 307 and the driven gear 305, so that the graphite powder in the groove of the discharge roller 304 can be discharged.

[0050] The detection mechanism 4 further comprises burners 401 arranged on the bottom wall of the box 1 and located on both sides of the combustion frame 403, and outer surfaces of the burners 401 are fixedly connected with slide rods 402 which are in sliding fit with the inner wall of the box 1, and the detection mechanism 4 is used for combustion detection of the crushed and quantified graphite.

[0051] By arranging the detection mechanism 4, the combustion detection of the quantified graphite powder can be facilitated, the combustion temperature required by the graphite powder is set through the burners 401, the burners 401 continuously combust the graphite powder, and after the combustion time of the graphite powder is reached, the combustion product after combustion can be manually taken out and weighed, the volatilization of the graphite powder after combustion can be obtained by comparing and calculating the weight of the graphite powder after falling from the quantification assembly, and the purity of the graphite can be converted.

[0052] In addition, the weight sensor 303 and the burner 401 in the utility model are both conventional devices known by those skilled in the art and can be purchased on the market, and the model can be selected or customized according to actual needs, and the setting mode, the installation mode and the electrical connection mode can be operated by those skilled in the art according to the requirements of the instruction manual, and thus will not be described here.

[0053] Working principle: when the purity of the graphite is detected, the crushing roller 202 is driven by the external driving device and can rotate, at this time, the graphite material is put into the crushing roller 202 through the inclined plate 203 for crushing, and the graphite powder is limited to fall into the storage frame 301 for quantification and weighing through the discharge frame 204.

[0054] At this time, the weight sensor 303 can detect the weight data of the graphite powder after it falls completely. When the purity of the graphite powder is tested, the weight sensor 303 controls the start of the double-output shaft motor 306, so that the double-output shaft motor 306 drives the driven gear 305 and the discharge roller 304 to rotate through the driving gear 307, so that the discharge roller 304 can fall in batches in sequence to avoid blockage. At the same time, the discharge roller 304 can drive the first sprocket 3015 to rotate through the second sprocket 3016 and the chain 3017, so that the first sprocket 3015 extrudes and pushes the two arc-shaped transmission blocks 3012, so that the arc-shaped transmission blocks 3012 contract through the spring telescopic rod 3010 and the fixed block 309 to store energy, and the transmission plate 3013 pushes the knocking plate 308 to swing outward. When the extrusion plate 3014 rotates 90 degrees, the energy stored in the spring telescopic rod 3010 can be released, so that the knocking plate 308 and the knocking head 3011 can knock and vibrate on the surface of the storage frame 301, so that the graphite powder adsorbed on the inner wall of the storage frame 301 falls into the discharge roller 304 and is discharged. When a small amount of graphite powder is detected, the number of rotations of the discharge roller 304 can be controlled, and the graphite powder stored in the discharge roller 304 can be discharged in batches.

[0055] The falling graphite powder falls into the combustion frame 403. At this time, the burner 401 is started to burn the graphite powder in the combustion frame 403, so that the graphite powder is fully burned and cooled. The combustion frame 403 is pulled out through the slide rod 402, and the burned combustion product is taken out and weighed. By comparing the weight of the graphite powder falling after the weighing of the quantitative assembly and calculating, the volatility of the graphite powder after burning can be obtained, so that the purity of the graphite can be calculated.
