Description

Technical Field

[0001] The present invention relates to the technical field of crushers, in particular to a jaw crusher for producing ceramsite sand and a crushing method. Background Art

[0002] In the production of expanded clay sand, kaolin, shale, coal gangue and other materials need to be crushed for the subsequent process. Kaolin, shale and coal gangue are all raw materials with relatively low hardness. When crushing kaolin, if the water content of kaolin is too high or the particle size is fine, it is easy to stick together in the crushing cavity, forming a "bridge" phenomenon, which hinders the falling of materials and affects the crushing efficiency of the jaw crusher. Usually the material is squeezed and crushed in the crushing cavity. Due to the action of gravity and the flow characteristics of the material, the crushed material and the larger particles that are not fully crushed are easy to accumulate near the discharge port, especially when dealing with kaolin, which has a slightly higher humidity or greater viscosity. These materials are more likely to stick to each other and agglomerate at the bottom of the discharge port, forming a blockage, so it is important to clear the discharge outlet at the bottom of the jaw plate.

[0003] When a jaw crusher is blocked during discharge, the blockage needs to be cleared to improve the crushing efficiency. Generally, the internal structure of a jaw crusher is complex and compact, making it relatively difficult and time-consuming to clean. For example, in the "A Jaw Crusher with Anti-Blocking Function" with publication number "CN110898886B", water in the water storage chamber is pumped to the nozzle when the wheel rotates. The water not only reduces the smoke and dust generated during stone crushing, but also washes away the soil carried by the stones, reducing the accumulation of soil and causing blockage in the crushing chamber. However, simply flushing from above is not effective in clearing the interior of the jaw crusher, and the flushing process will cause excessive waste of water resources. Based on the above cleaning method, it is conceivable to use a mechanical structure to clear the blocked soil in combination with flushing to improve the clearing efficiency. Conventional clearing mechanisms are usually set in the blocked area or below the blocked area. However, since the movable jaw needs to swing back and forth close to the fixed jaw for crushing, it is not suitable for installation in a jaw crusher. If a clearing structure is installed at the bottom discharge, it is easy to affect the normal crushing process and discharge process.

[0004] Therefore, a jaw crusher for the production of expanded clay sand is provided, which can solve the problem of low efficiency of simple water flushing and unblocking, and can also solve the problem that when the mechanical structure is unblocked and flushed for blockage unblocking, the structure used for unblocking easily affects the normal crushing and feeding of the jaw crusher. Summary of the Invention

[0005] The purpose of the present invention is to provide a jaw crusher and crushing method for the production of expanded clay sand, which can enable the structure for dredging to enter between the movable jaw and the fixed jaw during dredging, thereby improving the crushing effect.

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 making creative efforts are within the scope of protection of the present invention.

[0050] Example 1: Please refer to Figures 1 to 8 The present invention provides a technical solution: a jaw crusher for producing expanded clay sand, comprising a movable jaw 1 for swinging and extruding, a frame 2 being provided on the outside of the movable jaw 1, a fixed jaw 3 for cooperating with the movable jaw 1 to complete crushing being provided on the right side of the movable jaw 1, the fixed jaw 3 being installed inside the frame 2, the frame 2 being provided with a driving assembly 4 for driving the movable jaw 1 to swing, the driving assembly 4 for driving the movable jaw 1 to move of the jaw crusher is a mature existing technology, when the motor rotates, the belt drives the pulley to rotate, thereby rotating the eccentric shaft, and the rotational motion of the eccentric shaft is converted into the periodic reciprocating motion of the movable jaw 1, which will not be described in detail.

[0051] The jaw crusher also includes: a movable plate 5, which is arranged at the bottom of the movable jaw 1, and a movable pipe 6 for introducing a flushing water source is fixedly inserted inside the movable plate 5. A movable ring 11 is fixed to the outer wall of the movable pipe 6, and a spring 10 is fixed between the movable ring 11 and the movable plate 5. A first electric telescopic rod 12 is fixed to the bottom left side of the movable jaw 1, and a movable frame 13 is fixed to the output end of the first electric telescopic rod 12. The movable frame 13 is fixed to the outer wall of the movable ring 11 away from the output end of the first electric telescopic rod 12, and a flushing component 9 is arranged on the right part of the movable pipe 6. The flushing component 9 includes a retractable lifting pipe 91, and a water spray pipe 92 is arranged on the outside of the lifting pipe 91. The water spray pipe 92 is used to spray water to flush the movable jaw 1 and the fixed jaw 3. A dredging frame 15 is fixed to the top of the lifting pipe 91.

[0052] The transmission part 7 is used to control the lifting of the dredging frame 15. The transmission part 7 is arranged below the movable jaw 1. The lifting of the dredging frame 15 can dredge the movable jaw 1 and the fixed jaw 3, and the lifting of the dredging frame 15 can make the lifting pipe 91 move up and down to achieve extension and retraction.

[0053] A sliding groove 14 is formed at the bottom of the movable jaw 1 , and the top of the movable plate 5 slides inside the sliding groove 14 .

[0054] The transmission part 7 includes: a medium frame 71, which is arranged on the left side of the movable plate 5. The interior of the medium frame 71 is filled with medium. The interior of the medium frame 71 is provided with a first piston plate 72 that can move. The first piston plate 72 can move in the medium frame 71 to push the medium. A small rod 73 is fixed on the left side of the first piston plate 72. A mounting bracket 74 is fixed on the left side of the small rod 73. The left part of the mounting bracket 74 is fixed to the outer wall of the movable ring 11. The outer wall of the small rod 73 moves on the left part of the medium frame 71.

[0055] The transmission part 7 also includes: a lifting cylinder 75, which is arranged on the right side of the movable plate 5. The bottom of the lifting cylinder 75 is fixed to the straight pipe 93. The interior of the lifting cylinder 75 is equipped with a second piston plate 76 that can move up and down. The bottom of the dredging frame 15 is fixed to the lifting pipe 91. The top of the second piston plate 76 is fixed with a lifting rod 78 for driving the dredging frame 15 to move up and down. The outer wall of the lifting rod 78 moves inside the lifting cylinder 75. The top of the lifting rod 78 is fixed to the dredging frame 15. The way the piston plate is movably connected is the existing technology and will not be elaborated on. The connecting pipe 77 is fixedly inserted between the medium frame 71 and the lifting cylinder 75 and is used to connect the interior of the medium frame 71 and the lifting cylinder 75. The connecting pipe 77 is a retractable pipe.

[0056] A lining plate 16 is provided between the frame 2 and the movable jaw 1. One end of the lining plate 16 rotates with the movable jaw 1, and the other end rotates on a sliding frame 18. The sliding frame 18 slides in the frame 2. A hydraulic rod 17 is fixedly installed on the frame 2. The hydraulic rod 17 is used to adjust the position of the sliding frame 18.

[0057] The flushing assembly 9 also includes: a straight pipe 93 fixedly plugged into the bottom of the lifting pipe 91 , and a bent pipe 94 fixedly plugged between the straight pipe 93 and the movable pipe 6 , and the bent pipe 94 is used to connect the straight pipe 93 with the movable pipe 6 .

[0058] The top of the dredging frame 15 is tilted to facilitate the falling of the dredged sludge.

[0059] By adopting the above technical solution, a feeding assembly is provided on the top of the frame 2, which is used to place materials such as kaolin to be crushed from the top of the frame 2 into the crushing chamber between the movable jaw 1 and the fixed jaw 3. At this time, the driving assembly 4 causes the movable jaw 1 to swing and cooperate with the fixed jaw 3 to achieve material crushing.

[0060] A conveying assembly is also provided at the bottom of the frame 2, in the discharge area between the fixed jaw 3 and the movable jaw 1. The crushed material falls onto the conveying assembly provided at the bottom due to gravity to achieve discharge. It should be noted that the principle and specific structure of the conveying assembly are mature existing technologies and will not be elaborated on in detail.

[0061] When a lot of muddy materials are blocked at the discharge port between the fixed jaw 3 and the bottom of the movable jaw 1, the output shaft of the hydraulic rod 17 drives the sliding frame 18 to move to the left with the left part of the liner 16. In this way, when the movable jaw 1 swings, the discharge space between the bottom of the movable jaw 1 and the fixed jaw 3 becomes larger, which is conducive to the falling of the blocked material. At this time, the swing of the movable jaw 1 and the shaking component 8 to make the fixed jaw 3 shake can further facilitate the discharge of materials and improve the dredging effect. Moreover, since the space between the bottom of the movable jaw 1 and the fixed jaw 3 becomes larger, the dredging structure can be easily extended into the interior thereof so that the dredging can proceed normally. When crushing normally, the output shaft of the hydraulic rod 17 drives the sliding frame 18 to move to the right with the left part of the liner 16. At this time, the discharge space between the bottom of the movable jaw 1 and the fixed jaw 3 becomes smaller, so as to improve the crushing effect.

[0062] Then, the output shaft of the first electric telescopic rod 12 is retracted, so that the moving frame 13 moves to the right with the moving ring 11. Due to the elastic force of the spring 10, in the initial stage, the moving pipe 6, the moving plate 5, the transmission part 7 and the flushing assembly 9 all move to the right until the top of the moving plate 5 slides to the right rear position inside the chute 14. The moving plate 5 is limited by the chute 14 and can no longer move to the right. At this time, the dredging frame 15 comes to the bottom right side of the movable jaw 1, and then the output shaft of the first electric telescopic rod 12 is further retracted, which can make the moving frame 13, the moving ring 11, the moving pipe 6, the transmission part 7 and the flushing assembly 9 move to the right. The moving part 7 and the flushing assembly 9 move to the right, and at this time, since the moving plate 5 can no longer move, relative movement will occur between the moving ring 11 and the moving plate 5, and the spring 10 is compressed. With the cooperation of the small rod 73 and the mounting frame 74, the first piston plate 72 can slide from left to right inside the medium frame 71, so that the medium inside the medium frame 71 enters the inner bottom of the lifting cylinder 75 through the connecting pipe 77. Under the push of the medium, the second piston plate 76 can move upward with the lifting rod 78, thereby moving the dredging frame 15 upward for dredging.

[0063] When the dredging is completed, the output shaft of the first electric telescopic rod 12 extends, causing the movable frame 13, movable ring 11, movable tube 6, transmission part 7 and flushing assembly 9 to move to the left, and under the elastic force of the spring 10, the dredging frame 15 can move downward and reset.

[0064] It should be noted that the middle parts of the lifting pipe 91 and the connecting pipe 77 are both corrugated to ensure that they can expand and contract normally.

[0065] It should be noted that when dredging is being performed, as the output shaft of the first electric telescopic rod 12 contracts, when the first piston plate 72 moves to the right side of the medium frame 71, the output shaft of the first electric telescopic rod 12 can be slightly extended and contracted through the small reciprocating motion of the output shaft of the first electric telescopic rod 12. At this time, the first piston plate 72 slides inside the medium frame 71, thereby increasing or decreasing the medium at the bottom inner side of the lifting cylinder 75. The second piston plate 76 moves back and forth with the lifting rod 78, causing the dredging frame 15 to move up and down continuously, which is conducive to shaking off the sludge that is more severely adhered, thereby improving the effect of dredging the blockage.

[0066] During the dredging process, the left side of the mobile pipe 6 is connected to the hose, and water for flushing is pumped into the hose through an external water pump. The water enters the curved pipe 94 from the mobile pipe 6 and enters the interior of the straight pipe 93. The flushing water enters the interior of the lifting pipe 91 and is sprayed out from the water spray pipe 92. The dredging is carried out at the same time as the mechanical structure is used to dredge the pipe, so as to improve the dredging effect.

[0067] It should be noted that a sprinkler head may be installed on the water spray pipe 92 .

[0068] It should be noted that, when crushing, the structure for dredging of the device is located at the bottom of the movable jaw 1 during the crushing process, and does not affect the normal crushing process and the material feeding process.

[0069] It should be noted that the part used for dredging is not equipped with electronic control components to avoid damage to the electronic control components during dredging.

[0070] Embodiment 2: The technical solution of this embodiment is different from that of embodiment 1 in that: Figures 2 to 11 As shown, the flushing assembly 9 also includes: a rotating adjustment rod 95, which rotates inside the lifting pipe 91, and an elastic band 96 is fixed between the outer wall of the rotating adjustment rod 95 and the water spray pipe 92, and a rubber pad 97 is fixed on the outer wall of the water spray pipe 92 to allow the water spray pipe 92 to be deflected, and the outer wall of the rubber pad 97 is fixed to the top of the lifting pipe 91.

[0071] The fixing rod 98 is movable at the bottom of the rotating adjustment rod 95 , and the bottom of the fixing rod 98 is fixedly connected to the inner wall of the straight tube 93 .

[0072] The flushing assembly 9 further includes: a sliding groove 99, which is provided on the outer wall of the fixed rod 98 and is composed of three interconnected grooves, with the top and bottom ends being vertical grooves, and a spiral groove between the two vertical grooves;

[0073] The guide slider 910 is disposed on the inner wall of the rotation adjustment rod 95 , and moves inside the sliding groove 99 .

[0074] By adopting the above technical solution, when the output shaft of the first electric telescopic rod 12 is reciprocatingly extended and retracted in a small range, so that the dredging frame 15 reciprocates up and down to dredge, the guide slider 910 is located in the spiral part of the sliding groove 99. The up and down movement of the dredging frame 15 can make the lifting pipe 91 continuously extend and retract, and its length continuously changes, so that a relative movement in the up and down directions is generated between the fixed rod 98 and the rotating adjustment rod 95. At this time, the guide slider 910 slides in the internal spiral of the sliding groove 99, which can make the rotating adjustment rod 95 rotate, thereby changing the position and shape of the elastic belt 96. At this time, under the traction of the elastic belt 96, the angle of the water spray pipe 92 can be changed, so that the water spray pipe 92 swings in the horizontal direction, further increasing the flushing area, reducing the blind area of ​​flushing, and thus improving the dredging effect.

[0075] In the initial state, the guide slider 910 is located in the vertical groove inside the sliding groove 99. When the lifting tube 91 is extended in the initial state, the guide slider 910 slides in the vertical part in the sliding groove 99, and the rotating adjustment rod 95 does not rotate.

[0076] The jaw crusher further comprises: a shaking assembly 8 , which comprises a displacement sensor 81 fixedly connected to the inside of the frame 2 at a position corresponding to the movable jaw 1 , for monitoring the swinging direction of the movable jaw 1 .

[0077] The shaking assembly 8 includes a fixed plate 82 fixedly connected to the inside of the frame 2 and located on the right side of the fixed jaw 3. The fixed jaw 3 slides on the left side of the fixed plate 82. A second electric telescopic rod 83 for driving the fixed jaw 3 to rise and fall is fixed inside the fixed plate 82. The second electric telescopic rod 83 is fixedly connected to the part of the fixed jaw 3 that slides inside the fixed plate 82.

[0078] By adopting the above technical solution, the movable jaw 1 is in motion, which can play a role in throwing out some of the soil stuck on the movable jaw 1, while the fixed jaw 3 is in a stationary state, resulting in the inner side of the movable jaw 1 being more likely to adhere to impurities during operation, causing the interior of the crusher to be more easily clogged, requiring an increase in the frequency of cleaning and dredging, thereby affecting the displacement sensor 81 used to monitor the swinging position of the movable jaw 1. When the movable jaw 1 swings away from the fixed jaw 3, the displacement sensor 81 detects that the distance becomes smaller and transmits the signal to the external controller. The external controller controls the output shaft of the second electric telescopic rod 83 to quickly retract and reset, so that the fixed jaw 3 can shake when the movable jaw 1 is away from it, which plays a role in throwing off the clogged materials on the fixed jaw 3, thereby reducing the frequency of cleaning and dredging and improving the crushing efficiency.

[0079] When the output shaft of the second electric telescopic rod 83 contracts rapidly, the fixed jaw 3 moves upward with the clogged object adhered thereto. At this time, the large particles of material at the upper part have the effect of squeezing the clogged object adhered to the fixed jaw 3, which is conducive to the detachment of the clogged object.

[0080] After the flushing is completed, the movement of the fixed jaw 3 and the movable jaw 1 can achieve a certain effect of shaking off the flushing water.

[0081] The present invention also provides a crushing method for producing ceramsite sand, comprising the following steps:

[0082] S1, the kaolin and other materials to be crushed are placed from the top of the frame 2 into the crushing chamber between the movable jaw 1 and the fixed jaw 3 through the top conveying assembly;

[0083] S2, the driving assembly 4 makes the movable jaw 1 swing and cooperates with the fixed jaw 3 to crush the material. The crushed material falls to the conveying assembly arranged at the bottom due to gravity to realize discharge.

[0084] Working principle: When a lot of muddy materials are blocked at the discharge port between the fixed jaw 3 and the bottom of the movable jaw 1, the output shaft of the hydraulic rod 17 drives the sliding frame 18 to move to the left with the left part of the lining plate 16. In this way, when the movable jaw 1 swings, the discharge space between the bottom of the movable jaw 1 and the fixed jaw 3 becomes larger, which is convenient for the falling of the blocked material. Moreover, since the space between the bottom of the movable jaw 1 and the fixed jaw 3 becomes larger, the dredging structure can be easily extended into the interior.

[0085] Then, the output shaft of the first electric telescopic rod 12 is contracted, so that the moving frame 13 moves to the right with the moving ring 11. Due to the elastic force of the spring 10, in the initial stage, the moving tube 6, the moving plate 5, the transmission part 7 and the flushing assembly 9 all move to the right until the top of the moving plate 5 slides to the right rear position inside the slide groove 14. The moving plate 5 is limited by the slide groove 14 and can no longer move to the right. At this time, the dredging frame 15 comes to the bottom right side of the movable jaw 1, and then the output shaft of the first electric telescopic rod 12 is further contracted, which can make the moving frame 13, the moving ring 11, the moving tube 6, the transmission part 7 and the flushing assembly 9 move to the right. At this time, since the moving plate 5 can no longer move, a relative movement will occur between the moving ring 11 and the moving plate 5, and the spring 10 compresses The first piston plate 72 slides from left to right inside the medium frame 71 under the cooperation of the small rod 73 and the mounting frame 74, so that the medium inside the medium frame 71 enters the inner bottom of the lifting cylinder 75 through the connecting pipe 77. Under the pushing action of the medium, the second piston plate 76 can move upward with the lifting rod 78, thereby moving the dredging frame 15 upward for dredging. As the output shaft of the first electric telescopic rod 12 contracts, when the first piston plate 72 moves to the right side of the medium frame 71, the output shaft of the first electric telescopic rod 12 is reciprocated to extend and contract slightly, so that the dredging frame 15 moves up and down continuously, which is conducive to shaking off the sludge that is more severely adhered, thereby improving the effect of dredging the blockage.

[0086] The dredging frame 15 is made to move back and forth up and down, which can cause the position of the water spray pipe 92 installed on the top of the lifting pipe 91 to change continuously, thereby increasing the flushing area, reducing the blind area of ​​flushing, and further improving the dredging effect. At this time, relative movement in the up and down directions is generated between the fixed rod 98 and the rotating adjustment rod 95. At this time, the guide slider 910 slides on the internal spiral of the sliding groove 99, which can cause the rotating adjustment rod 95 to rotate, thereby changing the position and shape of the elastic band 96. At this time, under the traction of the elastic band 96, the angle of the water spray pipe 92 can be changed, thereby causing the water spray pipe 92 to swing in the horizontal direction, further increasing the flushing area.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
