Description

Technical Field

[0001] The invention belongs to the technical field of crushing devices, and in particular relates to a sample processing and crushing device with a replaceable copper inner wall. Background Art

[0002] Quartzite, as a type of hard rock widely distributed on the earth's surface, plays a vital role in many fields such as geological exploration, mineralogical research and material science due to its unique physical and chemical properties. Especially in the field of material science, the high hardness and wear resistance of quartzite make it an ideal raw material for preparing high-performance wear-resistant materials and abrasives. However, in order to process quartzite into particles or powders that meet specific particle size requirements, special crushing devices are required to achieve an efficient, energy-saving and environmentally friendly processing process.

[0003] In the Chinese patent with publication number CN208432450U, a laboratory sample crusher device is mentioned, which is provided with an upper clamping plate, a lower clamping plate and a spring. When the sample crusher is running, the vibration generated will act on the spring. Since the spring has a strong deformation capacity, the vibration generated by the sample crusher during operation can be reduced by deformation, thus solving the problem of large vibration amplitude of some previous sample crushers.

[0004] However, when the crushing device is grinding samples, especially when processing quartzite samples, due to the high hardness of quartzite and the fact that most commonly used crusher parts are made of iron, iron contamination is easily caused during the processing, which leads to inaccurate analysis results.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] See also Figures 1 to 8 As shown, a sample processing and crushing device with a replaceable copper inner wall comprises:

[0041] Supporting chassis 1;

[0042] A swing mechanism 2 is installed between the inner walls of both sides of the supporting chassis 1, a crushing cylinder 3 is installed on the inner side of the swing mechanism 2, an anti-pollution mechanism 4 is installed inside the crushing cylinder 3, a cylinder cover 5 is installed on the upper part of the outer surface of the crushing cylinder 3, and a crushing mechanism 6 is installed in the middle of the top of the cylinder cover 5;

[0043] The anti-pollution mechanism 4 includes an anti-pollution inner cylinder 41, a positioning block 42, a limit strip 43 and a clamping mechanism 44. The anti-pollution inner cylinder 41 is installed inside the crushing cylinder 3, the positioning block 42 is installed in the middle of the bottom end of the anti-pollution inner cylinder 41, and two limit strips 43 and two clamping mechanisms 44 are provided. The two limit strips 43 are respectively installed in the middle of the outer walls on both sides of the anti-pollution inner cylinder 41, and the two clamping mechanisms 44 are respectively installed in the upper parts of the two ends of the anti-pollution inner cylinder 41.

[0044] Depend on Figures 1 to 5 It can be seen that protective covers 7 are installed on the inner walls of both sides of the supporting frame 1, and limiting frames 8 are installed on the tops of the two protective covers 7. A positioning groove 9 is opened in the middle of the bottom inner wall of the crushing cylinder 3, and fixing grooves 10 are opened on the upper parts of the inner walls of both sides of the crushing cylinder 3. The middle parts of the inner walls of the other two sides of the crushing cylinder 3 are provided with limiting grooves 11.

[0045] The clamping mechanism 44 includes a clamping box 441, a guide groove 442, a squeezing spring 443 and a clamping block 444. The clamping box 441 is clamped and installed inside the fixed groove 10. The guide groove 442 is opened in the middle of the top end of the clamping box 441. The squeezing spring 443 is installed on the inner wall of one side of the clamping box 441. The clamping block 444 is installed on the other end of the squeezing spring 443, and the other end of the clamping block 444 passes through the inner wall of the other side of the clamping box 441.

[0046] As can be seen from the above, firstly, the anti-pollution inner cylinder 41 can be installed in the crushing cylinder 3, and the clamping limit of the limit strip 43 and the limit groove 11, and the clamping positioning of the positioning block 42 and the positioning groove 9, can accurately insert the clamping box 441 into the fixed groove 10. At the same time, the elastic action of the extrusion spring 443 causes the clamping block 444 to be first retracted into the clamping box 441, and then inserted into the wedge-shaped clamping groove of the fixed groove 10 under the extrusion of the extrusion spring 443, so as to realize the firm installation between the anti-pollution inner cylinder 41 and the crushing cylinder 3. Since the anti-pollution inner cylinder 41 is made of copper, it has good corrosion resistance and chemical stability, so it can effectively prevent iron impurities from contaminating the quartzite sample being processed, thereby ensuring the accuracy of the analysis results. In addition, since the copper material may need to be replaced due to wear after a period of use, the position of the movable clamping block 444 can be cancelled to cancel the fixation between the anti-pollution inner cylinder 41 and the crushing cylinder 3, so that the anti-pollution inner cylinder 41 can be conveniently disassembled for replacement, thereby reducing maintenance costs.

[0047] Specifically, refer to Figures 1 to 5 As shown, the clamping block 444 is set as an L-shaped structure, and one end face of the clamping block 444 is set as an inclined surface, a wedge-shaped clamping groove is set on the inner wall of the fixing groove 10, the anti-pollution inner cylinder 41 is set as a copper material, and the limiting frame 8 is set as an arc structure.

[0048] As can be seen from the above, the L-shaped structure of the clamping block 444 is convenient for sliding connection with the guide groove 442, and is also convenient for moving the position of the clamping block 444. The inclined surface of the clamping block 444 is conducive to its insertion into the wedge-shaped clamping groove of the fixed groove 10 to achieve a self-locking function. The properties of copper can be used to avoid iron contamination. The arc-shaped structure of the limit frame 8 can adapt to the movement trajectory of the limit block 254.

[0049] Embodiment 2:

[0050] refer to Figure 6 and Figure 7 As shown, the swing mechanism 2 includes an adjusting shaft 21, a driver 22, a small pulley 23, a synchronous belt 24 and a swing frame 25. The adjusting shaft 21 is installed between the inner walls of both sides of the supporting chassis 1 through a bearing, the driver 22 is installed at one end of the adjusting shaft 21, two small pulleys 23 and two synchronous belts 24 are provided, the two small pulleys 23 are respectively installed on both sides of the outer surface of the adjusting shaft 21, the two synchronous belts 24 are respectively sleeved and installed in the middle of the outer surfaces of the two small pulleys 23, and the swing frame 25 is installed between the upper parts of the two synchronous belts 24;

[0051] The swing frame 25 includes an adjusting frame 251, a large pulley 252, a limiting rod 253 and a limiting block 254. The adjusting frame 251 is installed between the inner walls on both sides of the supporting base frame 1 through bearings. Two large pulleys 252, two limiting rods 253 and two limiting blocks 254 are provided. The two large pulleys 252 are respectively installed on both sides of the outer surface of the adjusting frame 251, the two limiting rods 253 are respectively installed on both sides of the top of the adjusting frame 251, and the two limiting blocks 254 are respectively installed on the upper outer surfaces of the two limiting rods 253.

[0052] As can be seen from the above, in the process of the crushing mechanism 6 crushing the quartzite sample in the crushing cylinder 3, the driver 22 can be started to drive the small pulley 23 to rotate. At this time, through the transmission of the synchronous belt 24, the small pulley 23 drives the large pulley 252 to rotate, and then the adjusting frame 251 drives the crushing cylinder 3 to swing. In this way, the crushing mechanism 6 can contact the quartzite sample more fully, which not only significantly increases the contact area, but also ensures that each impact is more powerful and evenly distributed. The swinging design enables the crushing mechanism 6 to more effectively penetrate, cut and grind the quartzite sample, reducing dead angles in the crushing process. The final quartzite particles are finer and more uniform, meeting higher standards of crushing requirements and improving the crushing efficiency of the sample in the crushing cylinder 3. At the same time, when the adjusting frame 251 rotates, the limit rod 253 drives the limit block 254 to slide on the limit frame 8, ensuring the stability of the crushing cylinder 3 during the swinging process.

[0053] Preferably, reference Figure 6 and Figure 7 As shown, the middle part of the outer surface of the adjusting frame 251 is set as an annular structure, the large pulley 252, the small pulley 23 and the synchronous belt 24 are all located inside the protective cover 7, the limit block 254 is slidably connected to the limit frame 8, and the limit block 254 is set as an I-shaped structure, and the top end of the adjusting shaft 21 is lower than the bottom end of the crushing cylinder 3.

[0054] As can be seen from the above, the annular adjustment frame 251 can firmly install the crushing barrel 3, so that the protective cover 7 can protect these transmission components from external damage, the I-shaped structure prevents the limit block 254 from detaching from the limit frame 8, and the sliding connection allows the limit block 254 to move on the limit frame 8, so that the adjustment shaft 21 and the crushing barrel 3 do not contact each other, ensuring that the operation of the adjustment shaft 21 will not interfere with the operation of the crushing barrel 3.

[0055] Embodiment three:

[0056] refer to Figure 8As shown, the crushing mechanism 6 includes an isolation plate 61, a sealing gasket 62, a driving shaft 63, a driven shaft 64 and a crushing blade 65. The isolation plate 61 is installed on the inner wall of the cylinder cover 5, the sealing gasket 62 is installed on the bottom end of the isolation plate 61, the driving shaft 63 is installed at the middle of the top end of the isolation plate 61 through a bearing, and the top end of the driving shaft 63 is installed on the top inner wall of the cylinder cover 5 through a bearing, two driven shafts 64 are provided, and the two driven shafts 64 are respectively installed on both sides of the top end of the isolation plate 61 through bearings, and a plurality of crushing blades 65 are provided, and the plurality of crushing blades 65 are respectively installed on the outer surfaces of the driving shaft 63 and the two driven shafts 64;

[0057] The top ends of the two driven shafts 64 are both equipped with first gears 66 , the upper outer surface of the driving shaft 63 is equipped with a second gear 67 , the top end of the driving shaft 63 is equipped with a driving motor 68 , and the driving motor 68 is installed on the top end of the cylinder cover 5 .

[0058] As can be seen from the above, first, start the driving motor 68 so that the active shaft 63 drives the second gear 67 thereon to rotate. At this time, through the meshing transmission between the second gear 67 and the two first gears 66, the two driven shafts 64 can be driven to rotate, and the rotation direction of the active shaft 63 is opposite to that of the two driven shafts 64. The multiple crushing blades 65 on the active shaft 63 and the driven shaft 64 rotate rapidly accordingly, and the sample in the crushing cylinder 3 is fully crushed. Due to the staggered distribution of the multiple crushing blades 65, the crushing effect of the quartzite sample can be enhanced, thereby meeting the crushing demand for the quartzite sample and improving the crushing efficiency. In addition, through the sealing of the sealing gasket 62, the sealing of the connection between the isolation plate 61 and the anti-pollution inner cylinder 41 can be enhanced, and the thickness of the sealing gasket 62 is greater than the distance from the top surface of the clamping block 444 to the top surface of the clamping box 441, thereby ensuring that the clamping block 444 does not contact the isolation plate 61.

[0059] Preferably, reference Figure 8 As shown, the first gear 66 is meshed with the second gear 67, and the diameter of the first gear 66 is smaller than that of the second gear 67. The multiple crushing blades 65 on the driving shaft 63 and the driven shaft 64 are staggered and distributed with each other, and the isolation plate 61 is set to be made of stainless steel.

[0060] As can be seen from the above, gears of different diameters provide different speed ratios, which can speed up the speed of the first gear 66. The staggered distribution of multiple crushing blades 65 can provide a more uniform crushing effect. The stainless steel material of the isolation plate 61 has excellent strength and corrosion resistance, and can avoid iron pollution.

[0061] Application examples:

[0062] This design is used in experimental or production environments that require high-precision, pollution-free sample crushing, such as geological exploration laboratories, mineral processing enterprises, environmental monitoring stations and scientific research institutions. In the process of geological exploration, it is often necessary to crush and analyze the collected rock samples. In the process of mineral processing, it is necessary to crush and grind the ore. In the environmental monitoring station, it is necessary to crush and analyze soil, rock and other samples to evaluate the environmental quality. In the research of materials science, earth science and other fields, it is often necessary to crush samples.

[0063] This design provides an anti-pollution mechanism 4 and adopts a replaceable anti-pollution inner cylinder 41 made of copper to effectively prevent the contamination of samples by impurities such as iron, thereby ensuring the accuracy of the analysis results and providing accurate and reliable data analysis results for geological exploration, environmental monitoring and other fields. The copper anti-pollution inner cylinder 41 has wear resistance and a long service life, so that the device can operate stably for a long time and improve production efficiency. The design of the replaceable anti-pollution inner cylinder 41 makes maintenance more convenient and reduces maintenance costs. By providing a swing mechanism 2, the crushing cylinder 3 can be swung and shaken, so that the crushing mechanism 6 can be more fully in contact with the sample to improve the crushing effect. The use of an efficient crushing mechanism 6 can enhance the crushing effect of samples such as quartzite. The synergistic effect of the swing mechanism 2 and the crushing mechanism 6 enables the sample to be more fully crushed to meet the experimental needs.
