Description

Technical Field

[0001] The invention relates to the technical field of conveying and feeding, and in particular to a barite powder conveying and feeding system. Background Art

[0002] Barite powder is a fine powder processed from barite ore, the main component of which is barium sulfate. Due to its excellent physical and chemical properties, barite powder is widely used in oil and gas drilling, coatings, plastics, rubber, building materials and other industries. In oil drilling, barite powder is used as a mud weighting agent to help control downhole pressure and prevent blowouts.

[0003] In oil drilling, the use of barite powder begins with mixing it with water and other additives to form a mud base fluid. According to the drilling depth and formation pressure requirements, an appropriate amount of barite powder is added to increase the density of the mud, thereby effectively resisting the downhole pressure. The mixed mud is transported to the wellhead through the drilling pipeline, flows through the drill bit and brings back the rock cuttings produced on the ground. During the drilling process, the density, viscosity and fluidity of the mud are continuously monitored to ensure that its performance meets the requirements, and the amount of barite powder is adjusted in time. The addition of barite powder not only helps to maintain the wellhead pressure, but also prevents accidents such as blowouts, ensuring a safe and efficient drilling process.

[0004] During oil drilling, using an auger to transport barite powder to a mixing tank is a common way of conveying materials. However, since the powder particles are affected by airflow and mechanical friction during the conveying process, a large amount of powder mist is often generated. This powder mist may not only cause material loss, but also cause dust pollution to the operating environment. If the auger outlet is directly plugged into a sealed mixing tank, the sealing system may increase the difficulty of maintenance and cleaning. In addition, the internal pressure of the sealed tank may change with material conveying and chemical reactions, and the pressure is not easy to control. During the conveying process, the pressure in the tank will be transmitted to the auger conveying device, affecting the conveying of barite powder. For this reason, it is necessary to introduce a solution to suppress dust at the discharge port in the feeding system. Summary of the invention

DETAILED DESCRIPTION

[0019] 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.

[0020] refer to Figure 1-Figure 10 , a barite powder conveying and feeding system, comprising: Loading rack 100; A conveying pipe 101 is provided on the loading rack 100, and the conveying pipe 101 is connected to the hopper of the loading rack 100; An auger blade 102 disposed in the delivery pipe 101; A dust suppression cylinder 103 disposed at one end of the conveying pipe 101 is connected to the conveying pipe 101. A plurality of exhaust ports 104 are formed on the outer wall of the dust suppression cylinder 103. A feed port 105 is formed at the top of the dust suppression cylinder 103. A discharge port 106 is formed at the bottom of the dust suppression cylinder 103. A bag 107 is disposed in the dust suppression cylinder 103, and an upper cavity 108 and a lower cavity 109 are formed in the bag 107; The dust suppression component disposed in the dust suppression cylinder 103 is used to shrink the middle position of the bag 107 to discharge the air in the powder in the bag 107; The release component provided in the dust suppression cylinder 103 is used to control the opening and closing of the feed port 105 and the discharge port 106; A driving component is provided between the loading rack 100 and the conveying pipe 101, which is used to drive the auger blade 102 to rotate, and the dust suppression component can intermittently retract and release the cloth bag 107 when the auger blade 102 rotates; The dust suppression component can cause the release component to open the feed port 105 when the bag 107 is shrunk, and close the feed port 105 and the discharge port 106 when the bag 107 is released. The dust suppression component can cause the release component to open the discharge port 106 when the bag 107 is shrunk to a preset value. By setting up the dust suppression cylinder 103, when in use, the discharge port 106 at the bottom of the dust suppression cylinder 103 can be connected to a mixing tank for mixing barite powder with water and other additives (such as a polymer for preventing mud from losing water), the barite powder to be transported and fed is placed in the hopper of the feeding rack 100, and the driving component is started. The driving component can rotate the auger in the conveying pipe 101, so that the barite powder is transported to the dust suppression cylinder 103 through the rotation of the auger blades 102. In the initial state, the feed port 105 is in an open state and the distribution is closed. Bag 107 is in a retracted state and discharge port 106 is in an open state. Barite powder can be transported into the dust suppression cylinder 103 and received by the cloth bag 107 which is tightened in the middle. Cloth bag 107 will capture and filter dust in the air to prevent dust from spreading to the external environment. The dust suppression component can work with the rotation of the auger blade 102 to gradually release the retracted cloth bag 107. At this time, the releasing component can close the feed port 105 and the discharge port 106 to prevent excessive barite powder from being transported into the dust suppression cylinder 103, thereby preventing blockage.At the same time, bag 107 can prevent barite powder mixed with air from accidentally falling out of dust suppression cylinder 103 when released, ensuring smooth and safe transportation. As the transportation and feeding work proceeds, the dust suppression component can tighten the middle position of bag 107 again. During this process, feed port 105 is in an open state, and barite powder is still being transported into bag 107, gradually filling bag 107, and can fill the lower cavity 109 of bag 107. When the middle position of bag 107 is tightened, bag 10 The shape of bag 7 gradually tends to an hourglass shape. At this time, the barite powder transported in bag 107 can be compressed, and the air in bag 107 can be discharged, further reducing the escape of dust during transportation. The powder in the lower cavity 109 of bag 107 can be compressed into a group, which can increase the density of the powder and reduce the generation and leakage of dust. When the middle position of bag 107 gradually approaches the central axis of dust suppression cylinder 103 and shrinks to a preset value, the powder group is formed and the release component is released. The discharge port 106 can be opened, and the powder mass in the lower cavity 109 can fall into the mixing tank and be mixed with water and additives to realize the transportation and feeding of the barite powder, and effectively suppress the dust problem when the barite powder is fed. After the powder mass falls from the bag 107, when the dust suppression component releases the bag 107, the release component will close the discharge port 106 to prevent the uncompacted powder from falling out of the discharge port 106. At the same time, the feed port 105 is closed and temporarily does not accept the barite powder. In this process, The dust suppression mechanism in the bag 107 continues to work, isolating the fine dust from the barite powder, and only allowing the gas to escape from the bag 107, ensuring a clean and safe environment during the entire operation. In addition, when the dust suppression component releases the bag 107, the contracted part will be instantly straightened. This straightening action can effectively shake off the powder adhering to the inner surface of the bag 107, preventing the powder from accumulating on the inner surface of the bag 107, thereby reducing the risk of the powder adhering to the bag 107 during transportation. This not only helps to improve the efficiency of the bag 107, but also ensures that the conveyed powder can be discharged more smoothly, avoiding blockage and the inability to effectively discharge air. Through this design, the entire barite powder conveying system can effectively avoid dust leakage and reduce environmental pollution. At the same time, through the dynamic control of the cloth bag 107, the continuous and stable transportation of the powder is guaranteed, the problems of powder blockage, excessive accumulation, etc. are avoided, the optimal state of transportation efficiency and mixing effect is ensured, and the problem of large amount of powder mist generated due to mechanical friction and airflow in the process of conveying barite powder by the auger in the prior art is solved. These powder mists not only lead to material waste, but also cause serious dust pollution to the operating environment. In the traditional solution, the outlet 106 of the auger is directly connected to the sealed mixing tank. Although the dust overflow is suppressed to a certain extent, it increases the complexity of the sealing system, and the cleaning and maintenance process is cumbersome.The introduction of dust suppression devices reduces the system's sealing requirements and reduces the difficulty of maintenance and cleaning. These improvements not only improve the transportation efficiency of barite powder, but also reduce dust pollution and the difficulty of equipment maintenance, thereby improving the reliability of the overall system and the safety of the operating environment.

[0021] As a further solution of the present invention, the dust suppression component includes a rotating shaft 200 disposed in the dust suppression cylinder 103, a first traction rope 201 is connected to the rotating shaft 200, and one end of the first traction rope 201 is connected to the cloth bag 107 and is located in the middle of the inner wall of the cloth bag 107; By setting the rotating shaft 200, when the rotating shaft 200 rotates, it can drive the first traction rope 201 to tighten or release, thereby dynamically adjusting the middle of the bag 107. This design can effectively compress the powder in the bag 107 during the barite powder transportation process and reduce the escape of dust.

[0022] As a further solution of the present invention, the dust suppression component also includes two fixed rings 202 connected to the dust suppression cylinder 103, a connecting ring 203 is provided on the inner side of the fixed ring 202, a preset spacing is provided between the fixed ring 202 and the connecting ring 203, a limiting rod 204 is connected to the fixed ring 202, one end of the cloth bag 107 passes through the gap between the fixed ring 202 and the connecting ring 203 and is connected to a moving ring 205, the moving ring 205 is slidably connected to the limiting rod 204, a first spring 206 is connected between the moving ring 205 and the fixed ring 202, the connecting ring 203 is connected to the limiting rod 204, and the limiting rod 204 can support the position of the connecting ring 203, so that a gap can be formed between the connecting ring 203 and the fixed ring 202 for the cloth bag 107 to pass through; By setting the connecting ring 203, the connecting ring 203 can limit the shape of the cloth bag 107, so that the cloth bag 107 can be reversed on the connecting ring 203, and the first spring 206 can limit the position of the two ends of the cloth bag 107. In the initial state, the cloth bag 107 can be tightened in the dust suppression cylinder 103. When the rotating shaft 200 rotates to pull the cloth bag 107 through the first traction rope 201, the two ends of the cloth bag 107 are gradually released upward from between the connecting ring 203 and the fixed ring 202, and the first spring 206 is compressed to generate potential energy. When the rotating shaft 200 subsequently rotates in the reverse direction, the first spring 206 releases the potential energy, which can make the contracted cloth bag 107 tightened again, and the powder attached to the inner wall of the cloth bag 107 will be shaken off to prevent the powder from accumulating.

[0023] As a further solution of the present invention, the release component includes an iris opening and closing mechanism 300 disposed at the discharge port 106, and a connecting pipe 301 located in the feed port 105, the connecting pipe 301 is connected to the delivery pipe 101, a guide ring 302 is disposed in the connecting pipe 301, a first lead screw 303 is disposed on the rotating shaft 200, and a threaded tube 304 slidably connected to the connecting pipe 301 is threadedly connected to the first lead screw 303; By setting up the iris opening and closing mechanism 300, the discharge port 106 can be flexibly opened and closed. In addition, by setting up the first screw 303 and the threaded tube 304, the first screw 303 can drive the threaded tube 304 to slide along the connecting tube 301 by utilizing the threaded connection method. When the threaded tube 304 moves upward to the position of the guide ring 302, the guide ring 302 can be closed, and the powder transported by the auger blade 102 can be temporarily stored in the connecting tube 301, thereby achieving the purpose of opening and closing the feed port 105.

[0024] As a further solution of the present invention, the outer wall of the rotating shaft 200 is provided with a plurality of connecting grooves 305, a push rod 306 is slidably sleeved in the connecting groove 305, a second spring 307 is connected between the push rod 306 and the connecting groove 305, and a top groove 308 adapted to the push rod 306 is provided on the inner wall of the first lead screw 303, and the top groove 308 is a semi-spherical groove; By setting the second spring 307, the second spring 307 can limit the position of the push rod 306, so that it cooperates with the top groove 308 to form a certain friction force. When the rotating shaft 200 rotates forward to reel in the first traction rope 201 to shrink the cloth bag 107, the friction between the push rod 306 and the top groove 308 can be used to rotate the first lead screw 303 to move the position of the threaded tube 304 upward through the force of the thread. After the threaded tube 304 moves upward to the position of the guide ring 302, the movement position of the threaded tube 304 is limited. In the process of the rotating shaft 200 continuing to rotate and gradually shrinking the cloth bag 107, the push rod 306 can overcome the resistance of the second spring 307 and disengage from the top groove 308. At this time, the rotating shaft 200 can be idle in the first lead screw 303 to avoid continuing to push the threaded tube 304. This design can not only shorten the movement stroke of the threaded tube 304, but also ensure that when the rotating shaft 200 rotates forward, the closing operation of the feed port 105 can be completed quickly. In addition, when the rotating shaft 200 rotates in the opposite direction, the feed port 105 can be opened in time, so that the cloth bag 107 can be unfolded again to meet the transportation of the next batch of materials. Through this structure, the system can realize the rapid opening and closing control of the feed port 105, ensuring the continuity and accuracy of the feeding during the transportation process, while avoiding the blockage problem caused by excessive accumulation of materials. This design improves the flexibility and efficiency of material transportation, and effectively improves the stability of the equipment and the convenience of operation.

[0025] As a further solution of the present invention, the iris opening and closing mechanism 300 includes a fixed part 400 connected to the discharge port 106, a first slide rail 401 is provided on the fixed part 400, a rotating part 402 is provided at the bottom of the fixed part 400, a second slide rail 403 is provided on the rotating part 402, an iris fan blade 404 is provided between the fixed part 400 and the rotating part 402, a slider 405 slidably connected to the first slide rail 401 is provided at the top of the iris fan blade 404, and a sliding shaft 406 slidably connected to the second slide rail 403 is connected to the iris fan blade 404; By setting up the iris opening and closing mechanism 300, which includes a fixed part 400, a rotating part 402 and an iris blade 404, the opening and closing of the discharge port 106 can be effectively controlled. Specifically, the first slide rail 401 on the fixed part 400 is slidably connected to the slider 405 on the top of the iris blade 404, so that the iris blade 404 can move freely along the first slide rail 401. At the same time, the second slide rail 403 on the rotating part 402 is slidably connected to the slide shaft 406 on the iris blade 404, ensuring that the iris blade 404 can move synchronously with the rotation of the rotating part 402. This coordinated movement between the fixed part 400 and the rotating part 402 enables the iris blade 404 to accurately control the opening and closing of the discharge port 106 like the iris of a camera lens.

[0026] As a further solution of the present invention, a connecting shaft 407 is rotatably connected to the fixed part 400, and a first gear 408 is provided on the connecting shaft 407. A side opening 409 is provided on the outer wall of the rotating part 402, and a second gear 410 meshing with the first gear 408 is connected in the side opening 409, and the first gear 408 extends into the side opening 409. A second traction rope 411 is connected to the rotating shaft 200, and one end of the second traction rope 411 is wound around the connecting shaft 407; By providing the second traction rope 411, the iris opening and closing mechanism 300 can be effectively controlled. Specifically, one end of the second traction rope 411 is wound around the connecting shaft 407, and the connecting shaft 407 is provided with a first gear 408. The first gear 408 extends into the side opening 409 of the outer wall of the rotating part 402, and is matched with the second gear 410 in the side opening 409. When the rotating shaft 200 drives the second traction rope 411 to rotate, the traction rope will pull the connecting shaft 407 to rotate, thereby driving the first gear 408 to start rotating. The rotation of the first gear 408 drives the rotation of the entire rotating part 402 through the meshing action with the second gear 410. This design enables the iris opening and closing mechanism 300 to control the opening and closing of the iris blades 404 through the movement of the rotating part 402. In addition, when the discharge port 106 is opened, since the rotating shaft 200 is still rotating and the second traction rope 411 is still being pulled, the subsequent pulling action of the second traction rope 411 can cut the entire piece of powder dough, and the powder dough is properly divided into smaller parts before falling into the discharge port 106. This design not only improves the material discharge efficiency, but also avoids the phenomenon in traditional designs that the powder dough is too dense and affects the subsequent mixing uniformity. During the entire release process, a small amount of powder may be produced, and it will not have a significant impact on the operating environment.

[0027] As a further solution of the present invention, a second screw 412 is threadedly connected to the connecting shaft 407, a third spring 413 is connected between the second screw 412 and the connecting shaft 407, a second traction rope 411 is wound around the second screw 412, a limiting ring 414 is connected to the connecting shaft 407, the limiting ring 414 is located at the bottom of the second screw 412, a connecting block 415 is connected to the fixing portion 400, the connecting shaft 407 is rotatably connected to the connecting block 415, a fourth spring 416 is connected between the first gear 408 and the connecting block 415, and the elastic potential energy of the fourth spring 416 is greater than that of the third spring 413; By providing the connection block 415, the connection block 415 can effectively support the connection shaft 407, so that it remains stable during operation. When the second traction rope 411 is rotated and pulled by the rotating shaft 200, the second screw 412 starts to rotate first, and the potential energy of the third spring 413 gradually accumulates. This design allows the second screw 412 to move downward through the force of the thread until it reaches the position of the limit ring 414. The design purpose of this structure is to ensure that the discharge port 106 will not be accidentally opened in the initial stage of tightening the cloth bag 107. After the second screw 412 reaches the position of the limit ring 414, when the rotating shaft 200 continues to rotate and continuously tighten the cloth bag 107, the second traction rope 411 can rotate the connection shaft 407 until the cloth bag 107 is tightened to a preset value, and the rotating part 402 can achieve the displacement of the iris blade to open the discharge port 106.

[0028] As a further solution of the present invention, the driving component includes a conveying shaft 500 rotatably connected to the conveying pipe 101, the auger blade 102 is connected to the conveying shaft 500, the conveying pipe 101 is connected to a motor 501, and a chain 502 is provided between the driving shaft of the motor 501 and the conveying shaft 500; By providing the motor 501, the conveying shaft 500 can be effectively driven to rotate, thereby driving the auger blade 102 connected thereto to rotate. The power provided by the motor 501 is transmitted through the chain 502, so that the conveying shaft 500 rotates in the conveying pipe 101 to realize the conveying of powder.
