Description

Technical Field

[0001] This invention relates to the field of barite powder detection and sampling technology, and in particular to a barite powder grinding and detection sampling mechanism. Background Technology

[0002] Barite powder is a key raw material in chemical, building materials, and oil and gas drilling industries. Its particle size distribution and purity directly determine the quality of downstream products. Therefore, regular sampling and testing are necessary during the barite grinding process. Currently, the industry mainstream uses Raymond mills for barite grinding. During processing, the Raymond mill crushes the barite raw material into powder through grinding components. Then, the low-pressure blower on the equipment introduces airflow, causing the powdered barite to rise with the airflow and be transported through conveying pipelines to subsequent dust collection or storage stages.

[0003] Existing technologies generally divide sampling into static sampling and dynamic sampling. Static sampling requires stopping the grinding equipment, opening the sampling port, and inserting a tool into the equipment to take a sample. This method requires frequent start-ups and shutdowns of the grinding production line, which seriously affects processing efficiency. Dynamic sampling usually uses existing powder in-situ samplers. Although these samplers can perform dynamic sampling, they require auxiliary power to drive the sampling module to move back and forth multiple times during the sampling process, which increases the sampling cost. Furthermore, existing powder in-situ samplers only have one sampling module. To ensure the purity of each sample, the sampling equipment needs to be disassembled and cleaned when taking multiple samples at multiple time periods, which reduces the sampling efficiency.

[0004] Therefore, there is an urgent need to provide a barite powder grinding and testing sampling mechanism that can improve grinding sampling efficiency and reduce sampling costs. Summary of the Invention

Multiple push plates arranged in a spiral pattern are installed on the rotating rods.

[0012] The guide arc plate and the guiding arc plate guide the rising airflow carrying grinding powder to the collection plate. The airflow in the collection plate flows out from between the two guide arc plates. The baffle separates the grinding powder from the airflow. The collection plate collects the grinding powder. The rotating rod controls the opening and closing of multiple guiding parts individually through multiple push plates.

The sampling unit used in the present invention is equipped with multiple collection parts and guide parts, which can perform multi-point dynamic sampling in a single sampling process. It can also cooperate with the adjustment unit to operate only one collection part and guide part at different time periods, thereby completing dynamic sample collection for multiple time periods. Furthermore, it eliminates the need for repeated installation and disassembly of the sampling equipment, avoiding the inconvenience of repeatedly starting and stopping the equipment for traditional single sampling, thus improving sampling efficiency. Multiple collection parts work independently and do not affect each other, thereby avoiding cross-contamination caused by sampling at different time periods and ensuring the purity of samples obtained at each time period.

[0023] 2. The sampling unit used in this invention fully utilizes the low-pressure airflow within the Raymond mill process during dynamic sampling, eliminating the need for additional power equipment such as fans and vacuum pumps, thus reducing equipment purchase and operating energy costs, and consequently lowering sampling costs.

Detailed Implementation

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figures 1-6A barite powder grinding and testing sampling mechanism includes a positioning ring plate 1 detachably connected to a conveying pipe by bolts, a driving unit 2 disposed on the positioning ring plate 1, and a sampling unit 3 connected to the driving unit 2. The sampling unit 3 includes multiple linearly and uniformly distributed collection parts 30. Each collection part 30 includes a collection plate 300 disposed on one side of the positioning ring plate 1. Limiting plates 301 are installed on both the left and right side walls of the collection plate 300. The collection plate 300 has a circular groove structure with its front and rear ends closing inward. The collection part 30 also includes two locking rods 306 disposed below two locking frames 303 respectively. At least two locking sleeves 305 are passed through the locking rods 306, and the locking sleeves 305 are fixedly connected to the limiting plates 301.

[0037] See Figure 1 , Figure 2 , Figure 6 and Figure 9 Two connecting rods 32 are detachably connected between two adjacent collection parts 30. Both ends of the connecting rods 32 are provided with connecting holes. The snap sleeves 305 between the two collection plates 300 are sleeved and connected to the corresponding connecting rods 32. The snap rods 306 between the two collection plates 300 are simultaneously inserted into the corresponding snap sleeves 305 and the corresponding connecting rods 32.

[0038] In actual operation, the collection plate 300 and the two limiting plates 301 form a collection frame. Before sampling, two collection frames and two connecting rods 32 are selected. The two ends of the two connecting rods 32 are respectively inserted into the corresponding snap-fit ​​sleeves 305 on the two adjacent limiting plates 301. Then, the two snap-fit ​​rods 306 are sequentially passed through the two snap-fit ​​sleeves 305 on the same limiting plate 301. The snap-fit ​​rods 306 pass through the snap-fit ​​sleeves 305 and at the same time pass through the corresponding connecting holes on the connecting rods 32, so as to realize the function of fixed connection between the snap-fit ​​sleeves 305 and the snap-fit ​​rods 306, thereby realizing the function of splicing the two collection frames. The steps of splicing the two collection frames are repeated until all the collection frames required for sampling are spliced.

[0039] See Figure 2 , Figure 6 and Figure 9 The collecting part 30 is connected to the guiding part 31. The guiding part 31 includes two guide arc plates 310 symmetrically arranged above the collecting part 30. The guide arc plates 310 have an upward-convex arc-shaped structure. A partition net 312 is installed between the two guide arc plates 310. The opposite ends of the two guide arc plates 310 are hinged to guide arc plates 311 and a torsion spring is provided at the hinge. A contact plate 313 is installed on the outer arc surface of the guide arc plate 311 near the upper end.

[0040] See Figure 9A rubber plate is provided on the inner side of the hinge joint between the guide arc plate 310 and the guide arc plate 311. The rubber plate is fixedly connected to both the inner arc surface of the guide arc plate 310 and the inner arc surface of the guide arc plate 311.

[0041] See Figure 5 , Figure 6 , Figure 7 and Figure 9 Each of the two limiting plates 301 has a snap-fit ​​frame 303 installed at its opposite ends. The snap-fit ​​frame 303 has a U-shaped structure with its opening facing the limiting plate 301. The middle section of the snap-fit ​​frame 303 is threadedly connected to a limiting screw 304. The guide part 31 also includes two snap-fit ​​pieces 314 that are snapped into the two snap-fit ​​frames 303 respectively. The snap-fit ​​pieces 314 have a U-shaped structure with their openings facing downwards and snap-fit ​​holes are provided on the vertical sidewalls away from the guide arc plate 310. The snap-fit ​​pieces 314 are inserted and engaged with the corresponding limiting screws 304. The two snap-fit ​​pieces 314 are simultaneously fixedly connected to the two guide arc plates 310 and the partition net 312.

[0042] In practice, after multiple collection frames are assembled, two fasteners 314, which are fixedly connected to two guide arc plates 310, are inserted into the corresponding two snap-fit ​​frames 303 on the collection frame. The fasteners 314 can be plate-shaped or frame-shaped, and there is no specific limitation here. Then, the two limiting screws 304 are rotated, and the limiting screws 304 pass through the corresponding snap-fit ​​holes, thereby limiting the fasteners 314. At this time, the two guide arc plates 310 are fixed between the two limiting plates 301 and above the collection plate 300 by the two fasteners 314. An air inlet channel 307 is formed between the guide arc plates 310 and the collection plate 300, and an exhaust channel 308 is formed between two adjacent guide arc plates 310. It should be noted that the sum of the cross-sectional areas of the two air inlet channels 307 on the same collection plate 300 is smaller than the cross-sectional area of ​​the exhaust channel 308, that is, the air intake volume is smaller. With a flow rate less than the exhaust volume, there will be no phenomenon of gas gradually accumulating inside the collection plate 300 and causing an increase in air pressure as the gas flows. This prevents the deposited grinding powder from flowing back with the gas, thereby avoiding sample loss after sampling. The two guide arc plates 311, which are hinged to the two guide arc plates 310, are positioned together with the guide arc plates 310 between the two limiting plates 301. In the initial state, the two guide arc plates 311 are pressed tightly against the outer arc surface of the collection plate 300 by the action of torsion springs, thereby sealing the air inlet channel 307. This prevents the automatic collection of samples when not sampling and also prevents external dust and impurities from entering the collection plate 300. The rubber plate is used to seal the gap at the hinge of the guide arc plate 310 and the guide arc plate 311. Repeat the steps of connecting multiple buckles 314 with the corresponding snap frames 303 until all the required number of guide parts 31 are fixedly connected to the collection part 30.

[0043] See Figure 1 , Figure 2 , Figure 6 and Figure 8 The driving unit 2 includes multiple guide rods 20 that slide through the lower half of the positioning ring plate 1. The right ends of the multiple guide rods 20 are jointly mounted on a mounting plate 21. Two mounting rods 22 are mounted on the left end of the mounting plate 21. A driving component 23 is mounted on the right end of the mounting plate 21. A baffle 24 is jointly mounted on the left end of the multiple guide rods 20.

[0044] See Figure 2 , Figure 6 and Figure 9 The snap-fit ​​sleeve 305 near the mounting plate 21 is sleeved and connected to the corresponding mounting rod 22, and the snap-fit ​​rod 306 near the mounting plate 21 is simultaneously inserted into the corresponding snap-fit ​​sleeve 305 and the corresponding mounting rod 22.

[0045] In specific operation, the driving component 23 can be an existing hydraulic drive device, or it can be an electric push rod, etc. After multiple guide parts 31 are fixedly connected to the collecting parts 30, the two snap-fit ​​sleeves 305 near the mounting plate 21 are sleeved and connected to the two corresponding mounting rods 22. Then, the corresponding snap-fit ​​rods 306 pass through the two snap-fit ​​sleeves 305 and the two mounting rods 22 at the same time, so as to realize the function of fixing multiple collecting parts 30 to the mounting plate 21. The multiple collecting parts 30 fixedly connected to the mounting plate 21 are located between the mounting plate 21 and the baffle 24. Multiple guide rods 20 are located in the lower half of the positioning ring plate 1, which facilitates the installation and disassembly of the collecting parts 30. Sealing gaskets (not shown in the figure) can be laid on the opposite ends of the mounting plate 21 and the baffle 24.

[0046] See Figure 1 The positioning ring plate 1 has a plurality of mounting holes evenly distributed in a ring shape.

[0047] In practice, after multiple collection units 30 are fixedly connected to the mounting plate 21, the positioning ring plate 1 is fixedly connected to the installation position of the existing Raymond mill upper conveying pipe side wall using existing bolts. Then, the drive unit 23 is started. The drive unit 23 drives multiple collection units 30 into the conveying pipe through the mounting plate 21 and the mounting rod 22 and they are distributed perpendicularly to it until the mounting plate 21 and the positioning ring plate 1 are in contact, thus achieving the function of sealing the positioning ring plate 1. Then, the Raymond mill is started and barite raw materials are continuously fed into the Raymond mill. The Raymond mill grinds the barite raw materials. At the same time, the existing blower introduces airflow into the Raymond mill. It should be noted that the airflow inside the Raymond mill is a low-pressure airflow. The airflow carries the powdered barite powder upward and moves it into the conveying pipe.

[0048] See Figure 2 and Figure 5The collecting part 30 also includes two wind baffles 302 symmetrically installed on the inner arc surface of the collecting plate 300 and in an inclined state, and the two wind baffles 302 are fixedly connected to the two ends of the collecting plate 300 respectively.

[0049] See Figure 1 , Figure 2 , Figure 5 and Figure 8 The barite powder grinding and sampling mechanism also includes an adjustment unit 4 connected to the drive unit 2. The adjustment unit 4 includes two rotating rods 40 that are symmetrically distributed front and back and rotatably connected to the drive unit 2. The rotating rods 40 pass through the mounting plate 21 and are rotatably connected to it. Multiple push plates 41 that are spirally distributed are installed on the rotating rods 40.

[0050] See Figure 1 , Figure 2 and Figure 8 The adjustment unit 4 includes two transmission gears 42 respectively installed on the right end of the rotating rod 40, and the two transmission gears 42 are connected together by an adjustment part 43.

[0051] See Figure 2 and Figure 8 The adjustment unit 43 includes a second drive component 430 mounted on the right end of the mounting plate 21 via a mounting base. The moving section of the second drive component 430 is equipped with a transmission frame 431 with a U-shaped structure. Both vertical sections of the transmission frame 431 are equipped with multiple evenly distributed gear teeth 432 at opposite ends. The gear teeth 432 mesh with the transmission gear 42.

[0052] In specific operation, the second driving component 430 can be an existing hydraulic drive device, or it can be an electric push rod, etc. Before sampling, the multiple collection parts 30 are in a closed state. After the Raymond mill has been working for a period of time, the second driving component 430 is started. The second driving component 430 drives the transmission frame 431 to move. The transmission frame 431 drives the multiple gear teeth 432 on both sides to mesh with the transmission gears 42 on both sides. The two transmission gears 42 drive the two rotating rods 40 to rotate. The two rotating rods 40 drive the multiple push plates 41 to rotate. The multiple push plates 41 are spirally distributed to ensure that during each rotation of the rotating rod 40, only one push plate 41 contacts and pushes against the corresponding contact plate 313. The two contact plates 313 under force drive the two corresponding guide arc plates 311 to rotate, causing them to separate from the outer arc surface of the collection plate 300, thereby opening the air inlet channel 307. At this time, the operation of the second driving component 430 is stopped, and the guide arc plates 311 and the guide arc plates 311 are closed. The guide arc plate 310, in conjunction with the guide arc plate, directs part of the airflow carrying grinding powder into the air inlet channel 307, and through the air inlet channel 307 into the collection plate 300. At the same time, the airflow collides with the baffle plate 302 inside the collection plate 300, reducing the airflow velocity and allowing the mixed grinding powder to separate from the airflow. The airflow inside the collection plate 300 is discharged through the exhaust channel 308. The baffle mesh 312 in the exhaust channel 308 further separates the airflow from the grinding powder, ensuring that the grinding powder can accumulate in the collection plate 300, realizing the function of grinding powder sampling. No external power is required during the sampling process; it only relies on the gas flow inherent in the normal grinding process, thereby reducing the sampling cost. After the collection plate 300 has sampled the grinding powder for a period of time, the second drive component 430 is activated again. The rotating rod 40 drives the working push plate 41 to separate from the corresponding contact plate 313. At this time, the torsion spring resets and drives the guide arc plate 311 to reset, thereby closing the air inlet channel 307.

[0053] After a period of time, simply restarting the drive unit 430 will repeat the previous sampling steps, and the next unsampled collection unit 30 will start working. The sampling steps will be repeated every certain period of time until all collection units 30 have completed sampling. At this point, the multiple collection units 30 have collected samples from different time periods of the same grinding process. The operation of each collection unit 30 is relatively independent and does not affect each other. The samples from different time periods will not interfere with each other. Moreover, only one installation of the sampling equipment is required to achieve sample sampling for multiple time periods, which effectively improves the efficiency and convenience of sample sampling.

[0054] After multiple samples are collected, the drive unit 23 is activated. The drive unit 23 moves multiple collection parts 30 out of the conveying pipe through the mounting plate 21 and the mounting rod 22 until the baffle 24 is in close contact with the positioning ring plate 1. Then, the snap rod 306 connected to the mounting rod 22 is pulled out, thereby separating the multiple collection parts 30 from the mounting plate 21. The multiple collection parts 30 can be taken out. The guide part 31 can be directly separated from the collection part 30 and the sample can be poured out. Alternatively, a material drop hole (not shown in the figure) can be opened in the middle of the lower end of the collection plate 300. The material drop hole is sealed by the sealing plate during sampling. When the sample is taken out, the material drop hole can be opened to take out the sample. The grinding test sampling is completed.

[0055] It should be noted that while existing technologies can also achieve dynamic sampling over multiple time periods, they require multiple sampling devices to be installed on the grinding equipment for sampling at different time periods, thus increasing sampling costs. However, in the present invention, only one sampling mechanism is needed to achieve sampling operations over multiple time periods, and there is no need to repeatedly install and disassemble the mechanism. The sampling mechanisms used are all ordinary mechanical components, without high-precision parts, and can be reused without the need for auxiliary power sampling. In summary, the above-mentioned solution of the present invention is a specific improvement based entirely on the existing technology and to solve the technical problems.
