Description

Technical Field

[0001] The invention relates to a powder sample processing device, in particular to an integrated processing mechanism for powder samples. Background Art

[0002] In the experimental process of coal mining, electric power, mining, metallurgy and other industries, the original samples need to be processed into test specimens through crushing, screening, mixing, shrinking and other technologies. The processed samples must be uniform and can ensure that the material composition and content of the overall original sample remain unchanged. In the processing of powder samples, the binector is the most commonly used equal-division sampling processing device. In the process of binector sampling, due to different sampling requirements, the samples will be divided through different numbers of binectors.

[0003] In the existing powder sample processing equipment, since the ore powder still contains a little moisture and will adhere to the grid, a filter is usually used to disperse the particle distribution at the upper end of the grid, and a pneumatic vibrator is used to disperse the particles more evenly. Although it can remove part of the moisture in the powder and allow the powder to pass through the filter and the grid smoothly, a part of the finer powder will be blown upwards accordingly, especially at the position of the first divider. The overflowing fine powder will directly spread into the external air, which not only causes the waste and loss of certain components in the ore, but also easily affects the environment.

[0004] Therefore, this case aims to provide an integrated processing mechanism for powder samples, which can perform preliminary filtration at the upper end of the grid slot and reduce the impact of particles with moisture in the powder on the material discharge. It can also vibrate the outside of the divider to increase the activity of the sticky material inside and suppress the upward dust, so that the powder can be evenly sampled while avoiding the loss and waste of raw materials.

[0020] The beneficial effects of the present invention are:

[0021] The conventional two-way divider uses a grid slot for material separation. In order to facilitate material separation, a filter screen is arranged on the grid slot, and then the filter screen is vibrated by air blowing. Although the normal material discharge effect can be achieved, for powdery materials with humidity, the air blowing method is actually of limited effect. Therefore, the present invention adds a wet material separation structure. When part of the wet material falling on the separation net slowly descends under its own gravity, the through frame descends at this time, and the plug plate on the lower side of the through frame is directly inserted into the hole position of the separation net, thereby pressing the wet material downward. However, in the process of being pressed downward, part of the wet material will overflow to the back of the entire separation net, causing some stickiness or granulation, affecting normal material discharge. Therefore, after the through frame descends, the lower top frame will rise accordingly, so that the lower top frame is inserted into the plug plate of the through frame to push out the dividing clamping boss in the plug plate, so that the dividing clamping boss scrapes the back of the separation net, thereby removing the sticky matter that may adhere to the back of the separation net, thereby ensuring the smoothness of the entire material discharge channel.

[0022] When the through-frame is in a normal blanking state, since the guide holes are staggered with the holes on the separation net, space can be reserved for setting up the plug-in plate, so that the plug-in plate can cooperate with the holes on the separation net during the up and down movements without hindering the normal blanking process.

[0023] The plug plate needs to pass through the holes on the separation net. In order to avoid obstruction when passing through the separation net, the clamping boss inside the plug plate needs to be designed inwardly. When the plug plate passes through the separation net, the clamping boss needs to be retracted into the plug plate through the outer chute of the plug plate to allow the plug plate to pass through the separation net smoothly. After passing through the separation net, the clamping boss slides out of the outer chute, thereby forming a bottom scraper without changing the structure of the separation net and the discharge pipe cavity.

[0024] During the process of the separation boss sliding in and out, it changes by the top pressure or retraction of the lower top frame. Therefore, in order to cooperate with the lower top frame, the separation boss in the present invention is first provided with a flat shaft that cooperates with the lower top frame, and the side of the flat shaft facing the lower top frame is a flat surface, so that during the upward movement of the lower top frame, it can cooperate with the sensitive cross-section of the flat shaft, allowing the convex plate connected to the flat shaft to be pushed out, so that the convex plate scrapes the bottom wall of the separation net.

[0025] After the lower top frame is withdrawn, the flat shaft and the convex plate will not retract automatically, but if they stay on the outside, the through frame and the plug plate cannot be reset. Therefore, the present invention provides a movable tie seat in the plug plate, so that the ring plate and the spring of the movable tie seat tightly hold the flat shaft, so that after the lower top frame is withdrawn, the flat shaft will be reset immediately, so that the plug plate can be retracted after it has played its due wall scraping role.

[0026] When the lower top frame moves upward, it not only acts on the inside of the flat shaft, but also acts on the space outside the plug plate. Specifically, the inner clamping block in the lower top frame is divided into two inner and outer pressure structures. One is to squeeze the flat shaft through the inner pushing part, and the other is to scrape the outer wall of the plug plate through the outer extrusion part. At the same time, the inclined table surface at the top of the outer extrusion part can also guide the sticky matter scraped off the convex plate to allow it to fall smoothly.

[0027] After the wet material is processed by the wet material separation structure on the inner side of the reducer and the situation in which the wet material separation structure may adhere to the back of the separation net, the present invention also provides a vibration material platform on the outer side of the reducer, which drives the sliding frame to move back and forth through the driving structure, and then drives the vibration spring to vibrate, so that the connecting frame connected to the reduction unit also vibrates, and the reduction unit is shaken to a certain extent, which not only promotes the movement of powder, but also can vibrate the air in the reduction unit to a certain extent, inhibit the upward movement of dust, and enable the dust with powder to descend smoothly and be sucked away by the exhaust structure.

[0028] After each separation in the divider, it is necessary to sample the separated powder samples to detect whether the samples meet the requirements. However, if the samples are still wet, it will actually greatly affect the detection data of the samples. Therefore, the present invention adds a full-section sampling structure. When the ore powder is discharged through the discharge tube cavity, the powder falls evenly in the temporary space formed by the receiving area and the outer isolation tube, and is heated by the heater. After the powder in the receiving area is unevenly distributed, the powder is poured downward. At this time, the powder in the receiving area has already been dried, and can be directly sampled by the sampler, so that the samples taken by the sampler are all dry powder samples, and the sample data obtained is relatively accurate.

[0029] In order to form a multi-cavity open structure of an outer isolation tube and fins, the heater of the present invention is not just a traditional circular cylindrical structure, but extends to the inside of the fins, thereby increasing the heated area and allowing the powder to be exposed to a larger heating surface during deposition, thereby enabling drier particles to be obtained during sampling.

The reducer 20 is divided into four reduction units 21 from top to bottom, and the top reduction unit 21 is 21 is connected to a feed end 30, the shrinking unit 21 includes a hopper 211 for receiving materials, the lower part of the hopper 211 is connected to a separator 212, the lower end of the separator 212 is communicated with a discharge pipe 213, the hopper 211 of the separator 212 at the lower end is connected to the discharge pipe 213 of the separator 212 at the upper end, the integrated processing mechanism also includes: a wet material separation structure 1, the grid groove inside the separator 212 is divided into a plurality of discharge pipe cavities, the wet material separation structure 1 includes a separation net 101 arranged at the bottom of the inner side of the hopper 211, the The holes on the separation net 101 correspond to the discharge tube cavity. A through frame 102 is movably provided at the upper end of the separation net 101. A plurality of plug plates 1024 are provided at the bottom of the through frame 102. A clamping boss 1025 that can be pushed out laterally is provided in the plug plates 1024. When the through frame 102 moves down, the plug plates 1024 penetrate the separation net 101. A lower top frame 103 is movably provided at the lower end of the separation net 101. When the lower top frame 103 moves up, it is inserted into the plug plates 1024 and pushes out the clamping boss 1025, so that the clamping boss 1025 can push the separation net 101. 1, and the sticky matter on the bottom surface of the whole-section sampling structure 2 is scraped off; the whole-section sampling structure 2, the discharge tube cavity includes a horizontal end for receiving materials and a vertical end for feeding materials, the whole-section sampling structure 2 is located in the discharge tube 213, the whole-section sampling structure 2 includes a rotating frame 201 located below a plurality of vertical ends, a cylindrical heater 202 is fixedly connected to the rotating frame 201, the outer side of the heater 202 is covered with an outer isolation cylinder 203, the outer side of the outer isolation cylinder 203 is provided with a receiving area, the sampler is located inside the receiving area, the sampler passes through the discharge tube 213 and is connected to the external sampling tube.

[0048] Before the ore powder is divided into equal parts, it needs to be ground by a grinder, and then the ground powder is fed into the reducer 20 through the feed end 30. In the present embodiment, the reducer 20 is divided into four reducing units 21, which undergo four-stage reducing. In fact, it can also be set to the other number of reducing units 21, for example, two groups, three groups, five groups, etc., depending on the composition of the ore powder to be screened.

[0049] During the unloading stage, the material can be automatically fed through a pipeline directly connected to the feed end 30, or it can be manually unloaded. In order to facilitate timely observation, workers can go up to the top reduction unit 21 through the operating platform 50 to observe and operate.

[0050] When receiving materials, materials output by different reduction units 21 need to be separated separately. Therefore, the material holding structure 60 of this embodiment includes a sliding rail 61 locked to the inner side of the frame 10, and a translation vehicle 62 is slidably provided on the sliding rail 61. A material holding hopper 63 is provided on the translation vehicle 62. The material holding hopper 63 is divided into a plurality of material holding cavities. A nut is fixedly connected to the outer side of the material holding hopper 63, and the nut is connected to a screw drive assembly 64. The purpose of driving the material holding hopper 63 to move left and right by the screw drive assembly 64 is to make the powder in the material holding cavity more uniform and avoid the phenomenon of excessive height of a single point of powder.

[0051] After the wet material separation structure 1 on the inner side of the reducer 20 has processed the wet material and the situation in which the wet material separation structure 1 may adhere to the back of the separation net 101, on the outer side of the reducer 20, the vibration platform 70 of this embodiment includes a connecting frame 71 fixedly connected to the outer side of the second reducing unit 21 from top to bottom, and a plurality of vibration springs 72 are arranged at the bottom of the connecting frame 71. The bottom of the vibration spring 72 is connected with a sliding frame 73, and the sliding frame 73 is movably matched with a guide rail 74 fixed to the frame 10. The sliding frame 73 reciprocates left and right through a driving structure 75, and the driving structure 75 drives the sliding frame 73 to move back and forth, thereby driving the vibration spring 72 to shake, so that the connecting frame 71 connected to the reducing unit 21 also shakes, so that the reducing unit 21 is shaken to a certain extent, which not only promotes the movement of powder, but also can vibrate the air in the reducing unit 21 to a certain extent, inhibit the upward movement of dust, and enable the dust with powder to smoothly descend and be sucked away by the exhaust structure.

[0052] Traditional two-way dividers all use grid slots to divide materials. In order to facilitate the division of materials, a filter screen is set on the grid slot, and then vibrates by air blowing. Although it can achieve the effect of normal material feeding, for powdery materials with moisture, the air blowing method is actually limited in effect. Therefore, the present invention adds a wet material separation structure 1. When the wet material that partially falls on the separation net 101 slowly descends under its own gravity, the through frame 102 descends at this time, and the plug plate 1024 on the lower side of the through frame 102 is directly inserted into the hole position of the separation net 101, thereby The wet material is pressed downward, but in the process of being pressed downward, some of the wet material will overflow to the back of the entire separation net 101, causing some stickiness or granulation, affecting normal material discharge. Therefore, after the through-frame 102 descends, the lower top frame 103 will rise accordingly, so that the lower top frame 103 is inserted into the plug plate 1024 of the through-frame 102 to push out the dividing clamping boss 1025 in the plug plate 1024, so that the dividing clamping boss 1025 scrapes the back of the separation net 101, thereby removing the sticky matter that may be attached to the back of the separation net 101, thereby ensuring the smoothness of the entire material discharge channel.

[0053] When the powder falls into the through-frame 102 shrinking unit 21, it will first pass through the through-frame 102. Specifically, the through-frame 102 includes a sliding through-plate 1021 that movably cooperates with the inner side of the blanking hopper 211. The sliding through-plate 1021 is provided with a plurality of guide holes 1022 that are staggered with the hole positions on the separation net 101. The sliding through-plate 1021 is driven by a push-down member 1023. In the normal blanking state, since the guide holes 1022 are staggered with the hole positions on the separation net 101, space can be reserved for setting the plug plate 1024, so that the plug plate 1024 can cooperate with the hole positions on the separation net 101 during the up and down movements without hindering the normal blanking process.

[0054] The plug plate 1024 needs to pass through the holes on the separation net 101. In order to avoid being obstructed when passing through the separation net 101, the clamping boss 1025 in the plug plate 1024 needs to be designed to be retracted. Preferably, the plug plate 1024 is a hollow structure, and a plurality of external chutes are provided on the top of the outer side of the plug plate 1024. After the clamping boss 1025 is pressed, it slides out along the external chute and scrapes the adhesion on the back side of the hole of the separation net 101. When the plug plate 1024 passes through the separation net 101, it is necessary to retract the clamping boss 1025 into the plug plate 1024 through the external chute of the plug plate 1024, so that the plug plate 1024 can pass through the separation net 101 smoothly, and after passing through the separation net 101, the clamping boss 1025 slides out from the external chute again, thereby forming the bottom scraping without changing the structure of the separation net 101 and the discharge pipe cavity.

[0055] During the process of the split clamping boss 1025 sliding in and out, it changes by pressing or retracting the lower top frame 103. Therefore, in order to cooperate with the lower top frame 103, the split clamping boss 1025 of this embodiment includes a convex plate 10251 that can slide in the outer chute, the inner side of the convex plate 10251 is a flat shaft 10252, the side of the flat shaft 10252 facing the lower top frame 103 is a flat surface, and the flat shaft 10252 and the convex plate 10251 are fixedly connected by a The movable tie seat 10253 at the inner top of the plug plate 1024 is reset, and the clamping boss 1025 is first provided with a flat shaft 10252 that cooperates with the lower top frame 103, and the side of the flat shaft 10252 facing the lower top frame 103 is a flat surface, so that during the upward process of the lower top frame 103, it can cooperate with the sensitive cross-section of the flat shaft 10252, so that the convex plate 10251 connected to the flat shaft 10252 can be pushed out, so that the convex plate 10251 scrapes the bottom wall of the separation net 101.

[0056] After the lower top frame 103 is withdrawn, the flat shaft 10252 and the protruding plate 10251 will not retract automatically. However, if they stay on the outside, the through frame 102 and the plug plate 1024 cannot be reset. Therefore, the movable tie seat 10253 of the present embodiment includes a mounting platform 531 fixedly connected to the inner top of the plug plate 1024, and two springs 532 are fixedly connected to the two sides of the mounting platform 531. The two springs 532 are connected to two ring plates 533, and the ring plates 533 are sleeved on the outer peripheral surface of the flat shaft 10252. By arranging the movable tie seat 10253 in the plug plate 1024, the ring plates 533 and the springs 532 of the movable tie seat 10253 can tightly hold the flat shaft 10252, so that after the lower top frame 103 is withdrawn, the flat shaft 10252 will be reset immediately, so that the plug plate 1024 can be retracted after it has played its due wall scraping role.

[0057] After the through frame 102 is in place, the lower top frame 103 also needs to move upward. Specifically, the lower top frame 103 includes a lower top plate 1031 corresponding to the sliding through plate 1021, and the lower top plate 1031 is provided with a plurality of inner clamping blocks 1032 corresponding to the plug plate 1024. The lower top plate 1031 is driven by an upward push piece 1033. When the lower top plate 1031 rises, the inner clamping blocks 1032 are clamped into the plug plate 1024 to squeeze the clamping boss 1025. The lower top plate 1031 is raised by the upward push piece 1033, so that the inner clamping blocks 1032 are embedded in the plug plate 1024.

[0058] When the lower top frame 103 moves upward, it not only acts on the inside of the flat shaft 10252, but also acts on the space outside the plug plate 1024. Specifically, the inner clamping block 1032 includes an inner pushing portion 10321 for squeezing the flat surface of the flat shaft 10252, and an outer squeezing portion 10322 spaced apart from the inner pushing portion 10321. The inner clamping block 1032 in the lower top frame 103 is divided into two inner and outer pressure structures. One is to squeeze the flat shaft 10252 through the inner pushing portion 10321, and the other is to scrape off the outer side wall of the plug plate 1024 through the outer squeezing portion 10322. Preferably, the end of the outer squeezing portion 10322 close to the through frame 102 is an inclined table surface, and the inclined table surface at the top of the outer squeezing portion 10322 can also guide the sticky matter scraped off the convex plate 10251 to allow it to fall smoothly.

[0059] After each separation in the divider, it is necessary to sample the separated powder sample to detect whether the sample meets the requirements. However, if the sample is still wet, it will actually greatly affect the detection data of the sample. Therefore, the present invention adds a full-section sampling structure 2. When the ore powder is discharged through the discharge tube cavity, the powder falls evenly in the temporary space formed by the receiving area and the outer isolation tube 203, and is heated by the heater 202. After the powder in the receiving area is unevenly distributed, the powder is poured downward. At this time, the powder in the receiving area has already been dried, and can be directly sampled by the sampler, so that the samples taken by the sampler are all dry powder samples, and the sample data obtained is relatively accurate.

[0060] In order to form a multi-cavity open structure of the outer isolation tube 203 and the fins 205, the heater 202 of this embodiment is an electric heating wire, and the receiving area is a plurality of chambers formed by the fins 205 inserted in the outer isolation tube 203. The heating surface of the electric heating wire is attached to the inner wall of the outer isolation tube 203 and extends to the inner side of the fins 205. The heater 202 is not just a traditional circular cylindrical structure, but extends to the inner side of the fins 205, thereby enlarging the heated area, allowing the powder to contact a larger heating surface during deposition, so that drier particles can be obtained during sampling.

[0061] During sampling, specifically, an inner groove is provided on the outer side of the outer isolation tube 203, and the sampler includes a sampling tube 2041 embedded in the inner groove. A plurality of sampling holes are provided on the sampling tube 2041, and the sampling tube 2041 is connected to the negative pressure structure of the external sampling tube. The sampling holes are sampled through the external negative pressure structure, so that the sampling tube 2041 can obtain dry samples.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
