Technical Field
[0001] This invention relates to the field of ore crushing technology, specifically to a longitudinally connected water gap crushing chamber. Background Technology
[0002] The water gap crushing chamber is an advanced technology based on pulsed power technology, which uses the electric explosion of metal wires to generate shock waves to crush ore. It mainly improves the efficiency of converting electrical energy into mechanical energy of shock waves by adjusting the output of high-voltage electrical energy and generating shock waves through the electric explosion of metal wires. The shock waves act on the rock as surface waves, accurately find the mineral-bearing fractures in the ore and deposit energy. Through shear and stretching action, the ore particles are preferentially crushed along the interface of valuable mineral grains, thereby achieving the purpose of crushing.
[0003] Most existing water gap crushing chambers have simple cylindrical shells. The area near the feed inlet of these chambers often lacks protective mechanisms, making it easy for ore to damage the top of the water gap discharger when it enters the chamber, thus affecting its lifespan. Furthermore, most existing water gap crushing chambers lack screening mechanisms at the bottom. After initial crushing, the ore is discharged through the discharge pipe below. However, the crushed ore may contain incompletely crushed pieces, requiring screening before being returned to the crushing chamber. This increases the workload and reduces crushing efficiency. Summary of the Invention
[0004] To address the aforementioned technical problems, a longitudinally connected water gap crushing chamber is provided. This technical solution solves the problems mentioned in the background section, where the existing water gap crushing chambers are mostly simple cylindrical shells with no protective mechanism near the feed inlet. When ore enters the crushing chamber, it can easily damage the top of the water gap discharger, thus affecting its service life. Furthermore, the existing water gap crushing chambers mostly lack a screening mechanism at the bottom. After the ore is crushed once, it is discharged through the discharge pipe below. The crushed ore may contain incompletely crushed ore, which needs to be screened after discharge and then poured back into the crushing chamber, increasing the workload of crushing and affecting the crushing efficiency.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The top of the ball rod is fixedly connected to the middle of the inner side of the shielding shell. The bottom of the ball rod is engaged with the top of the support column. A limiting cavity is opened in the middle of the top of the support column. The bottom of the ball rod is engaged with the inner side of the limiting cavity. There are multiple sets of buffer springs. Multiple sets of buffer springs are fixedly fixed at equal intervals on the inner surface of the limiting cavity. The inner side of multiple sets of buffer springs is fixedly connected to the spherical surface in the middle of the ball rod. The middle of the top of the sealing base plate is fixedly connected to the bottom of the support column.
[0012] An arc-shaped clamping plate is fixedly connected to the rear side of the upper surface of the feed hopper, and an arc-shaped groove is opened on the rear side of the lower surface of the semi-annular hanging plate. The arc-shaped clamping plate and the arc-shaped groove are interlocked with each other.

[0014] Preferably, a fixing threaded hole is provided in the middle of the upper part of the shielding shell, a positioning hole is provided in the middle of the circular sieve plate, and a fixing nut is provided in the middle of the upper part of the circular sieve plate. The fixing nut is connected through the positioning hole and the fixing threaded hole.
[0015] Preferably, the bottom of the crushing chamber is provided with a support platform, and a clamping cavity is provided between the bottom of the crushing chamber and the bottom of the sealing base plate, and the middle part of the inner side of the support platform is engaged with the clamping cavity.
[0016] Preferably, the protective steel mesh cover has a semi-annular emission cavity at the shock wave emission position of the series water gap discharger.
[0017] Compared with the prior art, the present invention provides a longitudinally connected water gap crushing chamber, which has the following advantages: it facilitates the protection of the series water gap when feeding ore into the crushing chamber, which helps to prevent ore from colliding with the series water gap and causing damage; it facilitates the scraping and cleaning of the outer wall of the feed hopper during the feeding process, which helps to prevent ore from accumulating and clogging the feed inlet; it facilitates the screening of unqualified ore during the ore crushing process, which helps to evenly float the screened unqualified ore to the gap on the series water gap discharger, which helps to improve the ore crushing effect; and it helps to prevent ore backflow from clogging the insertion hole when replacing the metal wire, which would affect the efficiency of the series water gap discharger being reinserted into the crushing chamber.
[0018] The system consists of a feed hopper, mounting column, guide hood, motor, drive gear, gear ring, scraper, and protective steel mesh. When ore is poured into the feed hopper, it slides down along the hopper's inclined angle. Upon reaching the inner wall of the mounting column, the column provides initial protection above the series water gap discharger. The ore continues to slide down the inclined angle of the mounting column. When it contacts the guide hood, the guide hood provides secondary protection above the series water gap discharger. Simultaneously, the guide hood guides the ore's sliding trajectory towards the inner wall of the crushing chamber, preventing the ore from moving away from the series water gap discharger during its descent. When ore falls into the crushing bin, a protective steel mesh covers the area below the series water gap discharger. A motor drives a fixed drive gear at the output end to rotate, which in turn drives a meshing gear ring to rotate. The rotating gear ring drives a scraper to rotate along the inner surface of the feed hopper. The rotating scraper scrapes and pushes the material onto the surface of the feed hopper, thus protecting the series water gap when ore is fed into the crushing bin. This helps prevent ore from colliding with and damaging the series water gap, and facilitates scraping and cleaning of the outer wall of the feed hopper during the feeding process, preventing ore from accumulating and clogging the feed inlet.
[0019] Through the design of a limiting ring plate, clamping ring plate, circular screen plate, ball rod, support column, limiting cavity, pushing protrusion, and sealing bottom plate, when the crushed ore falls onto the circular screen plate under the force of impact, the impact force generated by the falling ore and the ore's own weight will cause the circular screen plate to vibrate left and right. When the circular screen plate vibrates left and right, the ball rod fixed at its bottom will rotate in the limiting cavity opened at the top of the support column, causing the ore to slide left and right on the circular screen plate. When the circular screen plate vibrates, the crushed qualified ore will fall through the screen holes opened on the circular screen plate. When the crushed stone passes through the circular screen plate and falls onto the sealing bottom plate, it will be discharged through the discharge pipe fixed at the bottom of the sealing bottom plate. The rotating spiral... The stirring rod drives the pushing protrusions to rotate along the surface of the circular screen plate. The rotating pushing protrusions push the contacting circular screen plate, which, under the restriction of the shielding shell, rotates around the top of the support column. This causes the crushed ore on the circular screen plate to slide back and forth in multiple directions. When the ore slides on the circular screen plate and comes into contact with the screen holes, qualified crushed stones will pass through the screen holes and fall down. This facilitates the rapid screening of unqualified ore during the ore crushing process, and also facilitates the stirring of the water flow inside the crushing chamber. It also helps to evenly float the screened unqualified ore to the gap on the series water gap discharger, thereby improving the ore crushing effect.
[0020] With its pull-out cover, pull-out cavity, and protective steel mesh cover, when replacing the metal wire, the worker pulls the pull-out cover upwards, causing the series water gap discharger fixed in the middle of the pull-out cover to move upwards towards the pull-out cavity. This allows the series water gap discharger to slowly separate from the protective steel mesh cover and the pull-out cavity. At this time, the protective steel mesh cover blocks the floating ore in the vortex water flow, preventing ore from entering the inside of the protective steel mesh cover and affecting the re-insertion of the series water gap discharger into the crushing chamber. The series water gap discharger separates and slides out of the crushing chamber. The worker then places the new metal wire into the gap between the series water gap dischargers and re-inserts the series water gap dischargers into the protective steel mesh cover. This prevents ore backflow from clogging the insertion hole when replacing the metal wire, thus avoiding affecting the efficiency of re-inserting the series water gap discharger into the crushing chamber.

Detailed Implementation
[0031] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0032] Example 1
[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a longitudinally connected water gap crushing chamber includes a crushing chamber 1, a feeding mechanism 3, a filtering mechanism 4, a discharge pipe 5, and a series water gap discharger 6.
[0034] The feeding mechanism 3 includes a feeding hopper 31, an arc-shaped clamping plate 32, a semi-circular hanging plate 33, a mounting column 34, a diversion hood 35, a toothed ring 37, a scraper 38, a motor 39, a drive gear 310, a spiral stirring rod 311, and a pushing protrusion 312.
[0035] The feed hopper 31 is fixed to the top of the crushing chamber 1 by nuts. A semi-annular hanging plate 33 is snapped onto the rear side above the feed hopper 31. A mounting column 34 is fixedly connected to the middle of the front surface of the semi-annular hanging plate 33. A flow guide hood 35 is fixedly connected to the bottom of the mounting column 34. A toothed ring 37 is rotatably connected to the upper outer side of the mounting column 34. A scraper 38 is fixedly connected to the middle of the lower part of one end of the toothed ring 37. A spiral stirring rod 311 is fixedly connected to the bottom of the scraper 38. A spiral stirring rod 311 is fixedly connected to the bottom of the spiral stirring rod 311. A push-out protrusion 312 and a drive gear 310 are meshed in the middle of the upper rear side of the toothed ring 37. A motor 39 is located in the middle of the rear side of the upper surface of the semi-annular hanging plate 33. The output end of the motor 39 is fixedly connected to the middle of the top of the drive gear 310. A clamping groove 315 is opened in the middle of the upper surface of the mounting column 34. A pull-out cavity 316 is opened inside the mounting column 34. The pull-out cavity 316 is located below the middle of the clamping groove 315. A pull-out cover 314 is engaged inside the clamping groove 315. A series water gap discharger 6 is fixed in the middle of the inner side of 14. The series water gap discharger 6 is pulled and connected to the pull-out cavity 316. A protective steel mesh cover 313 is fixedly connected to the outer edge of the top of the inner side of the drain cover 35. There is a stone retention space between the bottom of the protective steel mesh cover 313 and the upper surface of the circular screen plate 43. The series water gap discharger 6 is pulled and connected to the middle of the inner side of the protective steel mesh cover 313. An arc-shaped card plate 32 is fixedly connected to the rear side of the upper surface of the feed hopper 31. The semi-circular hanging plate 33 is lower. An arc-shaped groove 36 is provided on the rear side of the surface. The arc-shaped clamping plate 32 is engaged with the arc-shaped groove 36. The semi-annular hanging plate 33 is clamped on the rear side above the feed hopper 31 by the arc-shaped groove 36 and the arc-shaped clamping plate 32. The bottom of the pushing protrusion 312 contacts the upper surface of the circular screen plate 43. The thickness of the pushing protrusion 312 is greater than the distance between the limiting ring plate 41 and the circular screen plate 43. The protective steel mesh cover 313 is provided with a semi-annular emission cavity at the shock wave emission position of the series water gap discharger 6.
[0036] In this embodiment, when the ore is poured into the feed hopper 31, it slides down along the inclined angle of the feed hopper 31. When the ore slides onto the inner wall of the mounting column 34, the mounting column 34 provides initial protection above the series water gap discharger 6. At this time, the ore continues to slide down along the inclined angle of the mounting column 34. When the ore contacts the guide hood 35, the guide hood 35 provides secondary protection above the series water gap discharger 6. At the same time, the guide hood 35 guides the sliding trajectory of the ore towards the inner wall of the crushing chamber 1, so that the ore moves away from the series water gap discharger 6 during the sliding and falling process. When the ore falls into the crushing chamber 1, the protective steel mesh cover 313 protects the bottom of the series water gap discharger 6, which helps to prevent the ore from hitting the series water gap discharger 6 during the falling process, thereby causing certain damage to the series water gap discharger 6.
[0037] When crushing ore, when placing the metal wire into the gap of the series water gap dynamo 6, the worker holds the pull-out cover 314 and inserts the series water gap dynamo 6, which is fixed in the middle of the pull-out cover 314, into the middle of the protective steel mesh cover 313 through the pull-out cavity 316. At this time, the pull-out cover 314 will move down and lock into the clamp groove 315 opened in the middle of the upper surface of the mounting column 34. Adjusting the output of high-voltage power allows high-voltage direct current to be passed into the multiple electrode seats provided in the series water gap dynamo 6. After the high-voltage direct current is applied to the metal wire provided on the electrode seat, the metal wire explodes to form a shock wave. The shock wave acts as a surface wave on the rock, accurately finding the ore-bearing fractures in the ore and depositing energy. Through shearing and stretching, the ore particles preferentially move along the valuable mineral ore. The interface of the ore grains breaks down, and the broken ore falls onto the circular screen plate 43 under the action of gravity and the impact of the shock wave. When the ore completes one crushing, the power supply to the motor 39 is connected, and the motor 39 drives the drive gear 310 fixedly connected to the output end to rotate. The rotating drive gear 310 drives the toothed ring 37 meshing with the front side to rotate. The rotating toothed ring 37 drives the scraper 38 fixedly connected to the middle of the bottom end to rotate along the inner surface of the feed hopper 31. The rotating scraper 38 scrapes and pushes the material on the surface of the feed hopper 31 that is in contact with the bottom, which helps to prevent the accumulation of ore on the feed hopper 31 from blocking the feed inlet. At the same time, it is convenient to scrape and clean the slag adhering to the inner surface of the feed hopper 31. The rotating scraper 38 This will cause the spiral stirring rod 311, which is fixed at the bottom, to rotate. Simultaneously, the rotation of the spiral stirring rod 311 will cause the water stored inside the crushing chamber 1 to vortex. The vortex water flow will cause the crushed ore falling onto the circular screen plate 43 to float upwards along with the vortex water flow. At the same time, the operator pulls up the pull-out cover 314, causing the series water gap discharger 6, fixed in the middle of the pull-out cover 314, to move upwards towards the pull-out cavity 316. This allows the series water gap discharger 6 to slowly separate from the protective steel mesh cover 313 and the pull-out cavity 316. At this point, the protective steel mesh cover 313 blocks the floating ore in the vortex water flow, preventing the ore from entering the inside of the protective steel mesh cover 313 and affecting the series water gap discharger. 6. The effect of re-inserting the crushing chamber: The series water gap discharger 6 separates and slides out of the crushing chamber 1. The worker places a new metal wire into the gap between the series water gap dischargers 6 and re-inserts the series water gap dischargers 6 into the protective steel mesh cover 313 for secondary crushing. When a small ore enters the inside of the protective steel mesh cover 313, the series water gap discharger 6 re-inserted into the inside of the protective steel mesh cover 313 will push the ore along with the water ripples stirred by the crushing chamber 1 to slide towards the mesh holes on the protective steel mesh cover 313 and slide out of the protective steel mesh cover 313. Alternatively, under the push of the series water gap discharger 6, it moves down to the bottom of the inside of the protective steel mesh cover 313 and slides out through the cavity at the bottom of the inside of the protective steel mesh cover 313.
[0038] Example 2
[0039] Please refer to Figure 3 and Figure 6 As shown, the filter mechanism 4 is located below the interior of the crushing chamber 1. The filter mechanism 4 includes a limiting ring plate 41, a circular screen plate 43, a shielding shell 44, a ball rod 45, a buffer spring 46, a limiting cavity 47, a support column rod 48, and a sealing bottom plate 49.
[0040] The limiting ring plate 41 is located below the inner wall of the crushing chamber 1 and is fixedly connected to the interior of the crushing chamber 1. The circular screen plate 43 is located below the limiting ring plate 41. The shielding shell 44 is located in the middle of the lower surface of the circular screen plate 43. The top of the ball rod 45 is fixedly connected to the middle of the inner side of the shielding shell 44. The bottom of the ball rod 45 is engaged with the top of the support column 48. A limiting cavity 47 is opened in the middle of the top of the support column 48. The bottom of the ball rod 45 is engaged with the inner side of the limiting cavity 47. There are multiple sets of buffer springs 46. Multiple sets of buffer springs 46 are fixedly fixed at equal intervals on the inner surface of the limiting cavity 47. The inner side of multiple sets of buffer springs 46 is fixedly connected to the spherical surface in the middle of the ball rod 45. The middle of the top of the sealing base plate 49 is fixed to the bottom of the support column 48. The sealing base plate 49 has three discharge pipes 5 fixedly connected at equal intervals in the middle of its lower surface. The outer edge of the upper surface of the sealing base plate 49 has a threaded cavity for mating. A threaded head 410 is snapped into the inner side of the threaded cavity. The top of the threaded head 410 is fixedly connected to the inner edge of the bottom of the crushing chamber 1. A fixed threaded hole 411 is opened in the middle of the upper part of the shield shell 44. A positioning hole is opened in the middle of the circular screen plate 43. A fixing nut 412 is provided in the middle of the upper part of the circular screen plate 43. The fixing nut 412 is connected through the positioning hole and the fixing threaded hole 411. A support platform 2 is provided at the bottom of the crushing chamber 1. A clamp cavity is provided between the bottom of the crushing chamber 1 and the bottom of the sealing base plate 49. The middle of the inner side of the support platform 2 is snapped into the clamp cavity.
[0041] In this embodiment, when the crushed ore falls onto the circular screen plate 43 under the force of impact, the impact force generated by the falling ore and the weight of the ore itself will cause the circular screen plate 43 to vibrate left and right. When the circular screen plate 43 vibrates left and right, the ball rod 45 fixedly connected to its bottom will rotate in the limiting cavity 47 opened at the top of the support column 48. During the rotation of the ball rod 45 in the limiting cavity 47, it will contact the buffer spring 46. The buffer spring 46 will buffer the impact force generated during the rotation of the ball rod 45 to prevent it from colliding with the inner wall of the limiting cavity 47, thereby improving the stability of the vibration of the circular screen plate 43. When the circular screen plate 43 vibrates, the crushed qualified ore will fall through the screen holes opened on the circular screen plate 43. During the fall, the crushed ore is blocked by the shielding shell 44 to prevent the fragments from falling into the limiting cavity 47. Inside, the trajectory of the rotating rod 45 is affected. When the crushed stone falls through the circular screen plate 43 onto the sealed bottom plate 49, it will be discharged through the discharge pipe 5 fixed at the bottom of the sealed bottom plate 49. Unqualified crushed stone will remain above the circular screen plate 43. When no ore falls, the rotating spiral stirring rod 311 will drive the bottom fixedly connected pushing protrusion 312 to rotate along the surface of the circular screen plate 43. The rotating pushing protrusion 312 will push the contacting circular screen plate 43 under the restriction of the shielding shell 44 fixed at the bottom center, and rotate around the top of the support column rod 48. This will cause the crushed ore on the circular screen plate 43 to slide back and forth in multiple directions on the circular screen plate 43. When the ore slides on the circular screen plate 43 and comes into contact with the screen holes on the circular screen plate 43, qualified crushed stone will fall through the screen holes, thereby screening and filtering the crushed ore.
[0042] The working principle and usage procedure of this device are as follows: During use, when ore is poured into the feed hopper 31, it slides down along the inclined angle of the feed hopper 31. When the ore slides onto the inner wall of the mounting column 34, the mounting column 34 provides initial protection above the series water gap discharger 6. At this time, the ore continues to slide down along the inclined angle of the mounting column 34. When the ore contacts the guide hood 35, the guide hood 35 provides secondary protection above the series water gap discharger 6. Simultaneously, the guide hood 35 guides the sliding trajectory of the ore towards the inner wall of the crushing chamber 1, causing the ore to move away from the series water gap discharger 6 during its sliding descent. When it falls into the crushing chamber 1, the protective steel mesh cover 313 protects the lower part of the series water gap dynamo 6. When the metal wire is placed in the gap of the series water gap dynamo 6, the worker holds the pull-out cover 314 and inserts the series water gap dynamo 6, which is fixed in the middle of the pull-out cover 314, into the middle of the protective steel mesh cover 313 through the pull-out cavity 316. At this time, the pull-out cover 314 will move down and lock into the clamping groove 315 opened in the middle of the upper surface of the mounting column 34. Adjusting the output of high-voltage power allows high-voltage direct current to pass through the multiple electrode seats provided in the series water gap dynamo 6. After the high-voltage direct current is applied to the metal wire provided on the electrode seat, the metal... The electric shock wave generated by the electric shock acts on the rock as a surface wave, precisely locating ore-bearing fractures and depositing energy. Through shearing and stretching, the ore particles preferentially break along the interfaces of valuable mineral grains. The broken ore falls onto the circular screen plate 43 under the influence of gravity and the force of the shock wave. The impact force generated by the falling ore and its own gravity cause the circular screen plate 43 to vibrate left and right. When the circular screen plate 43 vibrates left and right, the ball rod 45 fixedly connected to its bottom rotates within the limiting cavity 47 opened at the top of the support column 48. During the rotation of the ball rod 45 within the limiting cavity 47, it contacts the buffer spring 46, which then... Spring 46 buffers the impact force generated during the rotation of the ball rod 45, preventing it from colliding with the inner wall of the limiting cavity 47, thereby improving the stability of the circular screen plate 43 during vibration. When the circular screen plate 43 vibrates, the crushed qualified ore falls through the screen holes on the circular screen plate 43. During the fall, the crushed ore is blocked by the shielding shell 44 to prevent fragments from falling into the limiting cavity 47 and affecting the rotation trajectory of the ball rod 45. When the crushed stone passes through the circular screen plate 43 and falls onto the sealing bottom plate 49, it will be discharged through the discharge pipe 5 fixed at the bottom of the sealing bottom plate 49. Unqualified crushed stone will remain above the circular screen plate 43.
[0043] When the ore completes one crushing cycle, the power supply to the motor 39 is connected, and the motor 39 drives the drive gear 310 fixedly connected to the output end to rotate. The rotating drive gear 310 drives the gear ring 37 meshing with the front side to rotate. The rotating gear ring 37 drives the scraper 38 fixedly connected to the middle of one end of the bottom to rotate along the inner surface of the feed hopper 31. The rotating scraper 38 scrapes and pushes the material on the surface of the feed hopper 31 that is in contact with the bottom, which helps to prevent the accumulation of ore on the feed hopper 31 from clogging the feed inlet. At the same time, it facilitates the scraping and cleaning of the slag adhering to the inner surface of the feed hopper 31. The rotating scraper 38 drives the spiral stirring rod 311 fixedly connected to the bottom to rotate. At the same time, the spiral stirring rod 311 rotates during the process of crushing the ore chamber 1. The water stored inside generates a vortex flow, which causes the crushed ore falling onto the circular screen plate 43 to float upwards along the vortex flow. At this time, the rotating spiral stirring rod 311 drives the pusher protrusion 312 fixed at the bottom to rotate along the surface of the circular screen plate 43. The rotating pusher protrusion 312 pushes the circular screen plate 43 in contact with it. Under the restriction of the shielding shell 44 fixed at the bottom center, it rotates around the support column 48, thereby causing the crushed ore on the circular screen plate 43 to slide back and forth in multiple directions on the circular screen plate 43. When the ore slides on the circular screen plate 43 and comes into contact with the screen holes on the circular screen plate 43, qualified crushed stones will pass through the screen holes and fall down, thereby screening and filtering the crushed ore.
[0044] The operator pulls the pull-out cover 314 upwards, causing the series water gap discharger 6, which is fixed in the middle of the pull-out cover 314, to move upwards towards the pull-out cavity 316. This causes the series water gap discharger 6 to slowly separate from the protective steel mesh cover 313 and the pull-out cavity 316. At this time, the protective steel mesh cover 313 blocks the ore in the vortex water flow, preventing the ore from entering the inside of the protective steel mesh cover 313 and affecting the effect of re-inserting the series water gap discharger 6 into the crushing chamber. The series water gap discharger 6 separates and slides out of the crushing chamber 1. The operator places a new metal wire into the gap between the series water gap dischargers 6 and re-inserts the series water gap dischargers 6 into the protective steel mesh cover 313 for secondary crushing. This process can be repeated multiple times to crush the ore.
