Description

Technical Field

[0001] The present invention relates to the technical field of ore crushing, and specifically relates to a longitudinally connected water-gap ore crushing chamber. Background Art

[0002] Mineral resources are the "food" for industrial development, and the mining industry is the "cornerstone" of the national economic development. China is the world's largest manufacturing country, with the production and sales volume of metals both accounting for 50% of the global total and ranking first in the world for more than 10 consecutive years. However, resources such as iron, copper, aluminum, nickel, chromium, and cobalt are highly dependent on imports, with the external dependence exceeding 50%. China is also a major mining country, with the output of metal ores ranking first in the world, and the output of steel ranking first in the world for 17 consecutive years.

[0003] In the domestic development of mineral resources, mine solid waste accounts for 80% - 85% of the total industrial solid waste, and mining pollutes 2.4 billion m³ of groundwater per year, which is equivalent to the reservoir capacity of 1.5 Gezhouba Power Stations. The exhaust gas and dust from mining, beneficiation, and smelting are important sources of smog, accounting for 30% of the total industrial exhaust gas. Mine solid waste occupies 58,200 km² of land, which is equivalent to the area of 5 Tianjin cities.

[0004] The water-gap ore crushing chamber is an advanced technology based on pulsed power technology, which uses the electro-explosion of metal wires to generate shock waves to crush ores. It mainly improves the efficiency of converting electrical energy into the mechanical energy of shock waves by adjusting the output of high-voltage electrical energy. The shock waves act on the rock as surface waves, accurately find the ore-bearing fissures in the ore and deposit energy, and use the shearing and stretching effects to make the ore particles preferentially break along the interfaces of valuable mineral grains, so as to achieve the purpose of crushing.

[0005] Most of the existing water-gap ore crushing chamber bodies are simple circular tube shells, and there is generally no protection mechanism at the position of the water-gap ore crushing chamber near the feed port. When ores enter the crushing chamber, it is easy to damage the upper part of the water-gap discharger, thus affecting the service life of the water-gap discharger. Moreover, most of the existing water-gap ore crushing chamber bodies do not have a screening mechanism at the bottom. After the ores are crushed once, they will be discharged through the discharge pipe below. However, the crushed ores may contain incompletely crushed ores, and after the ore materials are discharged, they need to be screened and then poured into the crushing chamber again, which increases the workload of ore crushing and also affects the ore crushing efficiency. Summary of the Invention

[0006] To solve the above technical problems, a longitudinally connected water-gap ore-crushing chamber is provided. The present technical solution solves the problems in the above-mentioned background technology that the hulls of existing water-gap ore-crushing chambers are mostly simple circular tube shells, and there is mostly no protection mechanism at the position of the water-gap ore-crushing chamber near the feed inlet. When ore enters the ore-crushing chamber, it is easy to damage the upper part of the water-gap discharger, thus affecting the service life of the water-gap discharger. Moreover, most of the bottoms of the hulls of existing water-gap ore-crushing chambers are not provided with screening mechanisms. After the ore is crushed once, it will be discharged through the discharge pipe below. However, the crushed ore may contain incompletely crushed ore, and it needs to be screened again after the ore material is discharged and then poured back into the ore-crushing chamber, which increases the workload of ore crushing and also affects the efficiency of ore crushing.

[0013] The limiting ring plate is located below the inner wall of the ore crushing chamber and is fixedly connected to the inside of the ore crushing chamber. The circular sieve plate is located below the limiting ring plate. The shielding shell is located in the middle of the lower surface of the circular sieve plate. 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 clamped with the top of the support column rod. A limiting cavity is opened in the middle of the top end of the support column rod. The bottom of the ball rod is clamped inside the limiting cavity. There are multiple groups of buffer springs. The multiple groups of buffer springs are fixedly arranged on the inner surface of the limiting cavity at equal intervals. The inner sides of the multiple groups of buffer springs are fixedly connected to the spherical surface in the middle of the ball rod. The middle of the top end of the sealing bottom plate is fixedly connected to the bottom of the support column rod;

[0014] An arc-shaped clamping plate is fixedly connected to the rear side of the upper surface of the feed hopper. An arc-shaped clamping groove is opened on the rear side of the lower surface of the semi-circular hanging plate. The arc-shaped clamping plate and the arc-shaped clamping groove are clamped with each other. The semi-circular hanging plate is clamped above the rear side of the feed hopper through the arc-shaped clamping groove and the arc-shaped clamping plate.

[0017] Preferably, a support platform is arranged at the bottom of the ore crushing chamber. There is a clamping cavity between the bottom of the ore crushing chamber and the bottom of the sealing bottom plate. The middle of the inner side of the support platform is clamped with the clamping cavity.

[0018] Preferably, a semi-circular emission cavity is opened at the shock wave emission position of the protective steel wire mesh cover for the series water gap discharger.

[0019] Compared with the prior art, the present invention provides a longitudinally series-connected water-gap ore-crushing chamber, which has the following beneficial effects: it is convenient to protect the series-connected water gap when putting ore materials into the ore-crushing chamber, which is beneficial to preventing the ore from colliding with the series-connected water gap and causing damage to it; it is convenient to scrape and clean the outer wall of the feed hopper during the feeding process, which is beneficial to preventing ore materials from accumulating and blocking the feed inlet; it is convenient to screen the unqualified ore during the ore-crushing process; it is convenient to drive the selected unqualified ore to evenly float to the gap of the series-connected water-gap discharger, which is beneficial to improving the ore-crushing effect; it is convenient to prevent the ore from flowing back and blocking the jack when replacing the metal wire, which affects the efficiency of inserting the series-connected water-gap discharger into the ore-crushing chamber again.

[0020] Through the set feed hopper, mounting column, drainage cover, motor, driving gear, toothed ring, scraper and protective steel wire mesh cover, when the ore is poured through the feed hopper, the ore will slide down along the inclined angle of the feed hopper. When the ore slides onto the inner wall of the mounting column, the mounting column provides primary protection for the upper part of the series-connected water-gap discharger. At this time, the ore will continue to slide down along the inclined angle of the mounting column. When the ore contacts the drainage cover, the drainage cover provides secondary protection for the upper part of the series-connected water-gap discharger. At the same time, the drainage cover guides the sliding track of the ore towards the inner wall of the ore-crushing chamber, so that the ore is far away from the series-connected water-gap discharger during the sliding and falling process. When the ore falls into the ore-crushing chamber, the protective steel wire mesh cover provides protection for the lower part of the series-connected water-gap discharger. The motor drives the driving gear fixed to the output end to rotate, thereby driving the meshing toothed ring to rotate. The rotating toothed ring drives the scraper to rotate along the inner surface of the feed hopper. The rotating scraper scrapes and pushes the surface of the contacted feed hopper, which plays a role in protecting the series-connected water gap when putting ore materials into the ore-crushing chamber, is beneficial to preventing the ore from colliding with the series-connected water gap and causing damage to it, is convenient to scrape and clean the outer wall of the feed hopper during the feeding process, and is beneficial to preventing ore materials from accumulating and blocking the feed inlet.

[0021] Through the provided limit ring plate, clamp ring plate, circular sieve plate, ball rod, support column rod, limit cavity, pushing bump and sealing bottom plate, when the crushed ore falls onto the circular sieve plate under the push of the impact force, the impact force generated by the falling of the ore and the gravity of the ore itself will drive the circular sieve plate to vibrate left and right. When the circular sieve plate vibrates left and right, the ball rod fixed at its bottom will rotate in the limit cavity opened at the top of the support column rod, causing the ore to slide left and right on the circular sieve plate. When the circular sieve plate vibrates, the qualified crushed ore will fall through the sieve holes opened on the circular sieve plate. When the crushed stones pass through the circular sieve plate and fall onto the sealing bottom plate, they will be discharged through the discharge pipe fixed at the bottom of the sealing bottom plate. The rotating spiral stirring rod will drive the pushing bump to rotate along the surface of the circular sieve plate. The rotating pushing bump will push the contacted circular sieve plate to rotate in a circumferential manner above the support column rod under the restriction of the shielding shell, thereby driving the crushed ore on the circular sieve plate to slide back and forth in multiple directions on the circular sieve plate. When the ore contacts the sieve holes on the circular sieve plate during the sliding process on the circular sieve plate, the qualified crushed stone blocks will fall through the sieve holes, which facilitates the rapid screening of unqualified ore during the ore crushing process, facilitates the stirring of the water flow inside the ore crushing chamber, facilitates driving the unqualified ore screened out to float evenly to the gap of the series water gap discharger, and improves the ore crushing effect.

[0022] Through the provided pull cover, pull cavity and protective steel wire mesh cover, when replacing the metal wire, the staff pulls up the pull cover, thereby driving the series water gap discharger fixed in the middle of the pull cover to move upward to the upper part of the pull cavity, making the series water gap discharger slowly separate from the protective steel wire mesh cover and the pull cavity. At this time, the protective steel wire mesh cover blocks the floating ore in the vortex water flow to prevent the ore from entering the inside of the protective steel wire mesh cover and affecting the effect of the series water gap discharger being reinserted into the ore crushing chamber. The series water gap discharger separates and slides out of the ore crushing chamber. The staff places the new metal wire into the gap between the series water gap dischargers and re-inserts the series water gap discharger into the protective steel wire mesh cover, which facilitates preventing the ore from flowing back and blocking the jack when replacing the metal wire and affecting the efficiency of the series water gap discharger being reinserted into the ore crushing chamber again.

Detailed implementation manners

[0033] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0034] Embodiment 1

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 , as shown, a longitudinally series-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;

[0036] The feeding mechanism 3 includes a feeding hopper 31, an arc-shaped clamping plate 32, a semi-circular hanging plate 33, a mounting post 34, a drainage cover 35, a toothed ring 37, a scraper 38, a motor 39, a driving gear 310, a spiral stirring rod 311 and a pushing bump 312; the feeding hopper 31 is fixedly installed on the top of the ore crushing chamber 1 through nuts. A semi-circular hanging plate 33 is clamped at the rear side above the feeding hopper 31. The middle part of the front surface of the semi-circular hanging plate 33 is fixedly connected with a mounting post 34. The bottom of the mounting post 34 is fixedly connected with a drainage cover 35. The upper part outside the mounting post 34 is rotatably connected with a toothed ring 37. The middle part below one end of the toothed ring 37 is fixedly connected with a scraper 38. The bottom of the scraper 38 is fixedly connected with a spiral stirring rod 311. The bottom of the spiral stirring rod 311 is fixedly connected with a pushing bump 312. The middle part above the rear side of the toothed ring 37 is meshed and connected with a driving gear 310. A motor 39 is arranged in the middle part of the rear side of the upper surface of the semi-circular hanging plate 33. The output end of the motor 39 is fixedly connected with the middle part of the top end of the driving gear 310. A clamping groove 315 is opened in the middle part of the upper surface of the mounting post 34. A pulling cavity 316 is opened inside the mounting post 34. The pulling cavity 316 is located below the middle part of the clamping groove 315. A pulling cover 314 is clamped inside the clamping groove 315. A series water gap arrester 6 is fixed in the middle part of the inner side of the pulling cover 314. The series water gap arrester 6 is connected with the pulling cavity 316 in a pulling manner. The outer edge of the top end inside the drainage cover 35 is fixedly connected with a protective steel wire mesh cover 313. There is a stone retention space between the bottom of the protective steel wire mesh cover 313 and the upper surface of the circular sieve plate 43. The series water gap arrester 6 is connected with the middle part inside the protective steel wire mesh cover 313 in an up-and-down pulling manner. The rear side of the upper surface of the feeding hopper 31 is fixedly connected with an arc-shaped clamping plate 32. An arc-shaped clamping groove 36 is opened in the rear side of the lower surface of the semi-circular hanging plate 33. The arc-shaped clamping plate 32 and the arc-shaped clamping groove 36 are clamped with each other. The semi-circular hanging plate 33 is clamped at the rear side above the feeding hopper 31 through the arc-shaped clamping groove 36 and the arc-shaped clamping plate 32. The bottom of the pushing bump 312 is in contact with the upper surface of the circular sieve plate 43. The thickness of the pushing bump 312 is greater than the distance between the limiting ring plate 41 and the circular sieve plate 43. The protective steel wire mesh cover 313 is provided with a semi-circular emission cavity at the shock wave emission position of the series water gap arrester 6.

[0037] In this embodiment, when the ore is poured through the feed hopper 31, the ore will slide downward 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 primary protection above the series water gap discharger 6. At this time, the ore will continue to slide along the inclined angle of the mounting column 34. When the ore contacts the diversion cover 35, the diversion cover 35 provides secondary protection above the series water gap discharger 6. At the same time, the diversion cover 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 wire mesh cover 313 protects the lower part 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;

[0038] When crushing ore, when the wire is placed at the gap of the series water gap discharger 6, the operator holds the pull-out cover 314 and inserts the series water gap discharger 6 fixed in the middle of the pull-out cover 314 into the middle of the protective steel wire mesh cover 313 through the pull-out cavity 316. At this time, the pull-out cover 314 will move down and be stuck in the hoop groove 315 opened in the middle of the upper surface of the mounting post 34. Adjust the output of the high-voltage electric energy so that the high-voltage direct current is introduced into the multiple electrode seats provided in the series water gap discharger 6. After the high-voltage direct current is loaded onto the wire provided on the electrode seat, the wire is electrically exploded to form a shock wave. The shock wave acts on the rock in the form of a surface wave, accurately searching for the ore-bearing fissures in the ore and depositing energy, and causing the ore particles to be preferentially broken along the interface of the valuable mineral grains by the action of shear and tension. The crushed ore will fall onto the circular sieve plate 43 under the action of gravity and the impact force of the shock wave. When the ore is crushed for the first time, the power supply of the motor 39 is connected. The driving gear 310 fixedly connected to the output end is driven by the motor 39 to rotate. The rotating driving gear 310 will drive the toothed ring 37 meshed with the front side to rotate. The rotating toothed ring 37 will drive 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 will scrape and push the surface of the feed hopper 31 in contact with the bottom, which is beneficial to preventing the accumulation of ore materials on the feed hopper 31 from blocking the feed port, and at the same time facilitating the scraping and cleaning of the slag adhered to the inner surface of the feed hopper 31. The rotating scraper 38 will drive the spiral stirring rod 311 fixedly connected to the bottom to rotate. At the same time, during the rotation of the spiral stirring rod 311, the water stored inside the crushing chamber 1 will be driven to generate a swirling flow. The swirling water flow will drive the crushed ore falling onto the circular sieve plate 43 to float along the swirling water flow. At the same time, the operator pulls up the pull-out cover 314 upward, thereby driving the series water gap discharger 6 fixed in the middle of the pull-out cover 314 to move upward in the pull-out cavity 316, so that the series water gap discharger 6 is slowly separated from the protective steel wire mesh cover 313 and the pull-out cavity 316. At this time, the protective steel wire mesh cover 313 blocks the ore floating in the swirling water flow to prevent the ore from entering the inside of the protective steel wire mesh cover 313 and affecting the effect of the series water gap discharger 6 being reinserted into the crushing chamber. The series water gap discharger 6 is separated and slides out of the crushing chamber 1. The operator places a new wire into the gap between the series water gap dischargers 6 and re-inserts the series water gap discharger 6 into the protective steel wire mesh cover 313 for secondary ore crushing. When smaller ore enters the inside of the protective steel wire mesh cover 313, the series water gap discharger 6 reinserted into the inside of the protective steel wire mesh cover 313 will push the ore to slide towards the mesh holes on the protective steel wire mesh cover 313 along the water pattern stirred by the crushing chamber 1, slide out of the protective steel wire mesh cover 313, or move down to the bottom end inside the protective steel wire mesh cover 313 under the push of the series water gap discharger 6 and slide out through the hole cavity at the bottom end inside the protective steel wire mesh cover 313.

[0039] Embodiment 2

[0040] Please refer to Figure 3 and Figure 6 As shown, the filtering mechanism 4 is located below the inside of the ore crushing chamber 1. The filtering mechanism 4 includes a limiting ring plate 41, a circular sieve 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;

[0041] The limiting ring plate 41 is located below the inner wall of the ore crushing chamber 1 and is fixedly connected to the inside of the ore crushing chamber 1. The circular sieve 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 sieve plate 43. The top of the ball rod 45 is fixedly connected to the middle of the inside of the shielding shell 44. The bottom of the ball rod 45 is clamped to the top of the support column rod 48. A limiting cavity 47 is provided in the middle of the top end of the support column rod 48. The bottom of the ball rod 45 is clamped to the inside of the limiting cavity 47. There are multiple groups of buffer springs 46. The multiple groups of buffer springs 46 are fixedly arranged on the inner surface of the limiting cavity 47 at equal intervals. The inner sides of the multiple groups of buffer springs 46 are fixedly connected to the spherical surface in the middle of the ball rod 45. The middle of the top end of the sealing bottom plate 49 is fixedly connected to the bottom of the support column rod 48. Three discharge pipes 5 are fixedly connected at equal intervals in the middle of the lower surface of the sealing bottom plate 49. A docking thread cavity is provided at the outer edge of the upper surface of the sealing bottom plate 49. A docking thread head 410 is clamped to the inside of the docking thread cavity. The top of the docking thread head 410 is fixedly connected to the inner edge of the bottom of the ore crushing chamber 1. A fixing thread hole 411 is provided in the middle above the shielding shell 44. A positioning hole is provided in the middle of the circular sieve plate 43. A fixing nut 412 is provided in the middle above the circular sieve plate 43. The fixing nut 412 passes through the positioning hole and the fixing thread hole 411. A support platform 2 is provided at the bottom of the ore crushing chamber 1. There is a clamping cavity between the bottom of the ore crushing chamber 1 and the bottom of the sealing bottom plate 49. The middle of the inside of the support platform 2 is clamped to the clamping cavity.

[0042] In this embodiment, when the crushed ore falls onto the circular sieve plate 43 under the push of the impact force, the impact force generated by the falling of the ore and the gravity of the ore itself will drive the circular sieve plate 43 to vibrate left and right. When the circular sieve plate 43 vibrates left and right, the ball rod 45 fixedly connected to its bottom will rotate in the limit cavity 47 opened at the top of the support column rod 48. During the rotation of the ball rod 45 in the limit cavity 47, it will contact the buffer spring 46, and 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 limit cavity 47, thereby improving the stability of the vibration of the circular sieve plate 43. When the circular sieve plate 43 vibrates, the crushed qualified ore will fall through the sieve holes opened on the circular sieve plate 43. During the falling process of the crushed ore, the shielding shell 44 shields the limit cavity 47 to prevent the fragments from falling into the limit cavity 47 and affecting the rotation trajectory of the ball rod 45. When the crushed stones pass through the circular sieve plate 43 and fall onto the sealing bottom plate 49, they will be discharged through the discharge pipe 5 fixed to the bottom of the sealing bottom plate 49. The unqualified crushed stone blocks will remain above the circular sieve plate 43. When there is no ore falling, the rotating spiral stirring rod 311 will drive the extrusion convex block 312 fixedly connected to the bottom to rotate along the surface of the circular sieve plate 43. The rotating extrusion convex block 312 will push the circular sieve plate 43 in contact with it to rotate in a circular motion around the upper part of the support column rod 48 under the restriction of the shielding shell 44 fixed in the middle of the bottom end, thereby driving the crushed ore on the circular sieve plate 43 to slide back and forth in multiple directions on the circular sieve plate 43. When the ore contacts the sieve holes on the circular sieve plate 43 during the sliding process on the circular sieve plate 43, the qualified crushed stone blocks will fall through the sieve holes, thereby screening and filtering the crushed ore.

[0043] Working principle and usage process of this device: During use, when ore is poured into the feeding hopper 31, the ore will slide downward along the inclined angle of the feeding hopper 31. When the ore slides onto the inner wall of the mounting column 34, the mounting column 34 provides primary protection above the series water gap discharger 6. At this time, the ore will continue to slide along the inclined angle of the mounting column 34. When the ore contacts the diversion cover 35, the diversion cover 35 provides secondary protection above the series water gap discharger 6. At the same time, the diversion cover 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 wire mesh cover 313 provides protection below the series water gap discharger 6. When placing the metal wire at the gap on the series water gap discharger 6, the staff holds the pull-out cover 314 and inserts the series water gap discharger 6 fixed in the middle of the pull-out cover 314 into the middle of the protective steel wire mesh cover 313 through the pull-out cavity 316. At this time, the pull-out cover 314 will move downward and be stuck in the clamping groove 315 opened in the middle of the upper surface of the mounting column 34. Adjust the output of high-voltage electric energy so that high-voltage direct current is introduced into the multiple electrode seats provided in the series water gap discharger 6. After the high-voltage direct current is loaded onto the metal wire provided on the electrode seat, the metal wire undergoes electro-explosion to form a shock wave. The shock wave acts on the rock as a surface wave, accurately searching for ore-bearing fissures in the ore and depositing energy, and causing the ore particles to be preferentially broken along the interfaces of the valuable mineral grains by shear and tensile action. The broken ore will fall onto the circular sieve plate 43 under the action of gravity and the impact force of the shock wave. The impact force generated by the falling ore and the gravity of the ore itself will drive the circular sieve plate 43 to vibrate left and right. When the circular sieve 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 rod 48. During the rotation of the ball rod 45 in the limiting cavity 47, it will contact the buffer spring 46, and the buffer spring 46 buffers 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 sieve plate 43. When the circular sieve plate 43 vibrates, the qualified broken ore will fall through the sieve holes opened on the circular sieve plate 43. During the falling process of the broken ore, the shielding shell 44 shields the limiting cavity 47 to prevent broken blocks 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 sieve plate 43 and falls onto the sealing bottom plate 49, it will be discharged through the discharge pipe 5 fixed to the bottom of the sealing bottom plate 49. The unqualified crushed stone blocks will remain above the circular sieve plate 43.

[0044] When the ore is crushed once, the power supply of the motor 39 is connected. The driving gear 310 fixedly connected to the output end is driven by the motor 39 to rotate. The rotating driving gear 310 drives the toothed ring 37 meshed with the front side to rotate. The rotating toothed 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 surface of the feed hopper 31 in contact with the bottom, which is beneficial to preventing the accumulation of ore on the feed hopper 31 and blocking the feed port. At the same time, it is convenient to scrape and clean the slag adhered 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, during the rotation of the spiral stirring rod 311, the water stored inside the crushing chamber 1 will be driven to generate a vortex flow. The water flow generating the vortex flow will drive the crushed ore falling onto the circular sieve plate 43 to float upward along the vortex flow of the water. At this time, the rotating spiral stirring rod 311 drives the pushing convex block 312 fixedly connected to the bottom to rotate along the surface of the circular sieve plate 43. The rotating pushing convex block 312 pushes the circular sieve plate 43 in contact with it to rotate in a circumferential manner above the support column rod 48 under the limitation of the shielding shell 44 fixed in the middle of the bottom end, thereby driving the crushed ore on the circular sieve plate 43 to slide back and forth in multiple directions on the circular sieve plate 43. When the ore slides on the circular sieve plate 43 and contacts the sieve holes on the circular sieve plate 43, the qualified crushed stone blocks will fall through the sieve holes, thereby screening and filtering the crushed ore;

[0045] The staff pulls up the pull cover 314 upward, thereby driving the series water gap discharger 6 fixed in the middle of the pull cover 314 to move upward in the pull chamber 316, so that the series water gap discharger 6 slowly separates from the protective steel wire mesh cover 313 and the pull chamber 316. At this time, the protective steel wire mesh cover 313 blocks the ore embossed in the vortex water flow to prevent the ore from entering the inside of the protective steel wire mesh cover 313 and affecting the effect of the series water gap discharger 6 being reinserted into the crushing chamber. The series water gap discharger 6 separates and slides out of the crushing chamber 1. The staff places a new metal wire into the gap between the series water gap dischargers 6, and re-inserts the series water gap discharger 6 into the protective steel wire mesh cover 313 for secondary crushing. Repeating multiple times can crush the ore multiple times.
