Description

Technical Field

[0001] The invention relates to the field of crushing, and in particular to a barite crusher with less dust. Background Art

[0002] Crusher, also known as stone crusher, is a general term for mining crushing machinery. It mainly squeezes, hits, splits and other methods to make various large stones into small-size sand and gravel aggregate products that meet the requirements. They are used in the construction of roads, railways, bridges, mines, chemicals, water conservancy and hydropower industries. According to different crushing processes and crushing effects, crushers can be divided into many types. Traditionally, jaw crushers are mainly used for barite crushing, but there are also many problems in the crushing process;

[0003] In the traditional crushing process, there is no screening of the crushed materials. At the same time, during the crushing process, the crushed crystals may be mixed with foreign matter, which may be harder than the crystals. When the device encounters these hard objects during the crushing process, the crushing device has no protection mechanism, which can easily cause damage to the device and make it unable to work normally. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention solves the technical problems thereof by adopting the following technical solutions: a barite crusher with less dust, comprising a base, a crushing bin fixedly connected to the top of the base, an adjusting mechanism fixedly connected to the top of the crushing bin, a screening mechanism fixedly connected to the bottom of the base, a crushing mechanism fixedly connected to the top of the crushing bin, the crushing mechanism comprising a centrifugal shaft, a crushing plate slidably connected to the outer surface of the centrifugal shaft, connecting plates rotatably connected to the two ends of the centrifugal shaft, the inner wall of the connecting plate is fixedly connected to the outer surface of the crushing bin, the centrifugal shaft is driven to rotate by a transmission assembly, so that the centrifugal shaft drives the crushing plate to vibrate and fluctuate, and the tooth grooves and the adjusting plate on the surface are used to crush the passing crystals, and the jaw crushing is used to ensure that the crushed crystal materials can meet the crushing requirements to the greatest extent, and at the same time, compared with rotary crushing, this crushing method is not easy to be blocked, and also includes:

[0005] The protection mechanism includes a connecting block fixedly connected to the outer surface of the crushing plate, the inner wall of the connecting block is rotatably connected with a sliding block, the outer surface of the sliding block is symmetrically provided with an anti-collision mechanism, the inner wall of the anti-collision mechanism is slidably connected to the outer surface of the sliding block, the bottom of the anti-collision mechanism is fixedly connected with a bottom block, the inner wall of the bottom block is slidably connected with a spring plate, the bottom of the bottom block is fixedly connected to the inner wall of the crushing bin, and the outer surface of the bottom block is fixedly connected with a curved rod. During the crushing process, when the crushing plate vibrates during the crushing process, the connecting block drives the sliding block to rotate, and at the same time, the top block pushes the crushing plate on the surface of the crushing plate to ensure that the crushing work of the crushing plate is carried out normally.

[0006] Top blocks are symmetrically arranged at both ends of the curved rod, and the outer surface of the top block is slidably connected with a slide groove, and the bottom of the slide groove is fixedly connected to the inner wall of the crushing bin, and the outer surface of the top block is fixedly connected with a limiting block. When encountering foreign matter doped inside the crystal and the strength of the crushing plate is unable to crush it, the curved rod causes the top block to slide through elastic deformation, so that the crushing plate rotates an angle and the crushing work is stopped. At the same time, during the deformation process of the top block, the limiting block limits the deformation and bending amount of the top block, thereby preventing the top block from being broken and damaged due to being unable to withstand the deformation amount during the crushing process.

[0007] The anti-collision mechanism includes a fixed plate, the bottom of the fixed plate is fixedly connected to the top of the bottom block, the inner wall of the fixed plate is fixedly connected with a slot block, the top of the slot block is fixedly connected with a spring plate, the top of the slot block is fixedly connected with a curved plate, the inner wall of the slot block is symmetrically provided with spring blocks, the inner wall of the spring block is fixedly connected to the outer surface of the slot block, when the angle of the crushing plate changes, the slider slides backward, at this time the slider slides to push the spring block to allow the slider to pass, and at the same time the curved plate restricts the slider after the slider slides over the spring block, so that the slider cannot slide back, ensuring that the crushing plate will not rebound and stop the normal crushing work, and at the same time the spring block ensures that the impact during sliding is reduced to protect the device.

[0008] The top of the base is fixedly connected to a water tank, the top of the water tank is fixedly connected to a nozzle, the bottom of the base is symmetrically provided with legs, the top of the legs is fixedly connected to the bottom of the base, the outer surface of the crushing bin is fixedly connected to a transmission assembly, the outer surface of the transmission assembly is fixedly connected to the top of the centrifugal shaft. At the beginning of crushing, the nozzle drives the water in the water tank through the water pump and sprays it into the gap between the adjusting plate and the crushing plate, so that the crystal is continuously sprayed with water during the crushing process to ensure the wetness of the surface, ensure that the surface of the crushed crystal is wet during the crushing process, and reduce the generation of crushing dust.

[0009] The adjusting mechanism comprises a fixed shaft, the bottom of which is fixedly connected to the top of the crushing bin, an adjusting plate is rotatably connected to the outer surface of the fixed shaft, a fixed block is fixedly connected to the outer surface of the adjusting plate, a rotating block is rotatably connected to the inner wall of the fixed block, and a buffer block is fixedly connected to the outer surface of the rotating block. Before crushing, the size of the crystal can be crushed as needed, and the hydraulic rod can be adjusted to make the hydraulic rod push the adjusting plate to rotate, thereby changing the gap between the adjusting plate and the crushing plate, thereby effectively adjusting the size of the crushed product.

[0010] The outer surface of the adjusting plate is symmetrically provided with hydraulic rods, the inner wall of the hydraulic rods is rotatably connected to the outer surface of the adjusting plate, the bottom end of the hydraulic rods is fixedly connected to the inner wall of the crushing bin, the inner wall of the crushing bin is fixedly connected with a leak-proof plate, the top of the leak-proof plate is fitted with the bottom of the adjusting plate, the inner wall of the crushing bin is fixedly connected with a top plate, the top of the top plate is fitted with the inner wall of the leak-proof plate, during the adjustment process, since the leak-proof plate is made of elastic plate, during the adjustment process, the leak-proof plate always keeps in fit with the bottom of the adjusting plate under the action of the top plate, to prevent the existence of a gap at the bottom during the adjustment process, which causes the crushed residue to enter the interior.

[0011] The screening mechanism includes a screen bin, the outer surface of which is symmetrically provided with clamping plates, the opposite sides of which are fixedly connected to the outer surface of the screen bin, the inner wall of which is slidably connected with a screen plate, the outer surface of which is symmetrically provided with spring grooves, the inner walls of which are fixedly connected to the outer surface of the screen plate, the outer surface of which is symmetrically provided with control mechanisms, the inner walls of which are fixedly connected to the outer surface of the screen bin, and the crystals after being crushed fall into the screen bin through the bottom plate and are screened by the screen plate in the screen bin, the qualified crystals pass through the screen plate, and the unqualified crystals stay on the top of the screen plate, and the crushed crystals are automatically screened.

[0012] The control mechanism includes a base plate, the inner wall of the base plate is rotatably connected to a connecting rod, the end of the connecting rod away from the base plate is rotatably connected to a sliding rod, the outer surface of the sliding rod is fixedly connected to a magnetic ring, the top of the magnetic ring is fixedly connected to an adjusting cylinder, the outer surface of the sliding rod is slidably connected to a fixed groove, the inner wall of the fixed groove is fixedly connected to a magnetic plate, the top of the base plate is fixedly connected to the bottom of the sieve plate, and the inner wall of the fixed groove is fixedly connected to the outer surface of the sieve bin. When the weight on the top of the sieve plate reaches a certain level, the magnetic force between the magnetic plate and the magnetic ring cannot be controlled, and the sliding rod slides to make the connecting rod drive the sieve plate to rotate. During rotation, the elastic groove creates a gap between the sieve plate and the sieve bin, ensuring the smooth opening of the sieve plate and exporting unqualified products, so that the device can guide the crystals to the other side when facing unqualified products and the device opens the protective device.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention drives the slider to rotate by setting a connecting block, and at the same time, the top block pushes the crushing plate on the surface of the crushing plate to ensure the normal crushing work of the crushing plate, thereby avoiding the crushing plate being unable to be crushed and the device being unusable due to the inclusion of hard foreign matter inside the crystal ore during the crushing process.

[0015] 2. The present invention sets a curved rod to make the top block slide through elastic deformation, so that the crushing plate rotates an angle and the crushing work is stopped. At the same time, during the deformation process of the top block, the limiting block limits the deformation and bending amount of the top block, thereby preventing the top block from being unable to withstand the deformation amount during the crushing process and causing breakage and damage, resulting in the device being unable to work normally.

[0016] 3. The present invention provides a hydraulic rod to enable the hydraulic rod to push the adjusting plate to rotate, thereby changing the gap between the adjusting plate and the crushing plate, thereby effectively adjusting the size of the crushed product and improving the practicability of the device when facing different crushing requirements.

[0017] 4. The present invention sets a sieve plate, and screens through the sieve plate in the screen bin. The qualified crystals pass through the sieve plate, while the unqualified crystals stay on the top of the sieve plate. The crushed crystals are automatically screened, which reduces the tediousness of manual screening and improves the crushing quality.

[0018] 5. The present invention sets a magnetic plate and a magnetic ring. When the magnetic force cannot be controlled, the slide rod slides, so that the connecting rod drives the sieve plate to rotate. During the rotation, the elastic groove creates a gap between the sieve plate and the sieve bin, ensuring the smooth opening of the sieve plate and the unqualified products are discharged. When the device faces unqualified products and the device opens the protective device, it can guide the crystals to the other side to avoid mixing with qualified finished products, and cooperate with the crushing mechanism to ensure the safe operation of the device.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0030] Embodiment 1, as Figure 1-Figure 6 As shown, a dust-free barite crusher includes a base 1, a crushing bin 8 is fixedly connected to the top of the base 1, an adjusting mechanism 3 is fixedly connected to the top of the crushing bin 8, a screening mechanism 4 is fixedly connected to the bottom of the base 1, a crushing mechanism 2 is fixedly connected to the top of the crushing bin 8, and the crushing mechanism 2 includes a centrifugal shaft 23, a crushing plate 24 is slidably connected to the outer surface of the centrifugal shaft 23, and connecting plates 22 are rotatably connected to both ends of the centrifugal shaft 23. The inner wall of the connecting plate 22 is fixedly connected to the outer surface of the crushing bin 8, and the centrifugal shaft 23 is driven to rotate by a transmission assembly 5, so that the centrifugal shaft 23 drives the crushing plate 24 to vibrate and fluctuate, and the tooth grooves on the surface and the adjusting plate 33 are used to crush the crystal passing through, and the jaw crushing is used to ensure that the crushed crystal material can meet the crushing requirements to the greatest extent. At the same time, compared with rotary crushing, this crushing method is not easy to be blocked, and also includes:

[0031] The protection mechanism 21 includes a connecting block 213 fixedly connected to the outer surface of the crushing plate 24, the inner wall of the connecting block 213 is rotatably connected with a slider 215, the outer surface of the slider 215 is symmetrically provided with an anti-collision mechanism 216, the inner wall of the anti-collision mechanism 216 is slidably connected to the outer surface of the slider 215, the bottom of the anti-collision mechanism 216 is fixedly connected with a bottom block 211, the inner wall of the bottom block 211 is slidably connected with a spring plate 212, the bottom of the bottom block 211 is fixedly connected to the inner wall of the crushing bin 8, and the outer surface of the bottom block 211 is fixedly connected with a curved rod 217. During the crushing process, when the crushing plate 24 vibrates during the crushing process, the connecting block 213 drives the slider 215 to rotate, and at the same time, the top block 218 supports the crushing plate 24 on the surface of the crushing plate 24, ensuring that the crushing work of the crushing plate 24 is carried out normally, and avoiding the crushing plate 24 being unable to be crushed due to the inclusion of hard foreign matter inside the crystal ore during the crushing process, resulting in the breakage of the crushing plate 24 and the unusability of the device.

[0032] Top blocks 218 are symmetrically arranged at both ends of the curved rod 217, and the outer surface of the top block 218 is slidably connected with a slide groove 219. The bottom of the slide groove 219 is fixedly connected to the inner wall of the crushing bin 8, and the outer surface of the top block 218 is fixedly connected with a limiting block 214. When encountering foreign matter doped inside the crystal and the strength of the crushing plate 24 is unable to crush it, the curved rod 217 causes the top block 218 to slide through elastic deformation, so that the crushing plate 24 rotates an angle and stops the crushing work. At the same time, during the deformation process of the top block 218, the limiting block 214 limits the deformation and bending amount of the top block 218, thereby preventing the top block 218 from being unable to withstand the deformation amount during the crushing process and causing breakage and damage, resulting in the device being unable to work normally.

[0033] The anti-collision mechanism 216 includes a fixed plate 2165, the bottom of which is fixedly connected to the top of the bottom block 211, a slot block 2162 is fixedly connected to the inner wall of the fixed plate 2165, a spring plate 2163 is fixedly connected to the top of the slot block 2162, a curved plate 2164 is fixedly connected to the top of the slot block 2162, and spring blocks 2161 are symmetrically arranged on the inner wall of the slot block 2162, and the inner wall of the spring block 2161 is fixedly connected to the outer surface of the slot block 2162. When the angle of the crushing plate 24 changes, the slider 215 slides back. At this time, the slider 215 slides to push the spring block 2161 to allow the slider 215 to pass. At the same time, the curved plate 2164 restricts the slider 215 after the slider 215 slides over the spring block 2161, so that the slider 215 cannot slide back, ensuring that the crushing plate 24 will not rebound and stop the normal crushing work. At the same time, the spring block 2161 ensures that the impact during sliding is reduced to protect the device.

[0034] A water tank 6 is fixedly connected to the top of the base 1, a nozzle 7 is fixedly connected to the top of the water tank 6, legs 9 are symmetrically arranged at the bottom of the base 1, the top of the legs 9 is fixedly connected to the bottom of the base 1, a transmission assembly 5 is fixedly connected to the outer surface of the crushing bin 8, the outer surface of the transmission assembly 5 is fixedly connected to the top of the centrifugal shaft 23. At the beginning of crushing, the nozzle 7 drives the water in the water tank 6 through a water pump and sprays it into the gap between the adjusting plate 33 and the crushing plate 24, so that the water flow is continuously sprayed on the crystal during the crushing process to ensure the wetness of the surface, to ensure that the surface of the crushed crystal is wet during the crushing process, and to reduce the generation of crushing dust.

[0035] Example 2, based on Example 1, continue to refer to Figure 7-Figure 9 The adjusting mechanism 3 includes a fixed shaft 31, the bottom of the fixed shaft 31 is fixedly connected to the top of the crushing bin 8, the outer surface of the fixed shaft 31 is rotatably connected to an adjusting plate 33, the outer surface of the adjusting plate 33 is fixedly connected to a fixed block 32, the inner wall of the fixed block 32 is rotatably connected to a rotating block 36, and the outer surface of the rotating block 36 is fixedly connected to a buffer block 37. Before crushing, the size of the crystal can be crushed as needed, and the hydraulic rod 34 can be adjusted to make the hydraulic rod 34 push the adjusting plate 33 to rotate, thereby changing the gap with the crushing plate 24, and effectively adjusting the size of the crushed product, thereby improving the practicability of the device when facing different crushing requirements.

[0036] The outer surface of the adjusting plate 33 is symmetrically provided with hydraulic rods 34, the inner wall of the hydraulic rods 34 is rotatably connected to the outer surface of the adjusting plate 33, the bottom end of the hydraulic rods 34 is fixedly connected to the inner wall of the crushing bin 8, the inner wall of the crushing bin 8 is fixedly connected with a leakproof plate 38, the top of the leakproof plate 38 is fitted with the bottom of the adjusting plate 33, the inner wall of the crushing bin 8 is fixedly connected with a top plate 35, the top of the top plate 35 is fitted with the inner wall of the leakproof plate 38, and during the adjustment process, since the leakproof plate 38 is made of elastic plate, during the adjustment process, the leakproof plate 38 always keeps in fit with the bottom of the adjusting plate 33 under the action of the top plate 35, so as to prevent the existence of a gap at the bottom during the adjustment process, causing the crushed residue to enter the interior, affecting the normal operation of the adjusting mechanism 3, and increasing the difficulty of cleaning.

[0037] The screening mechanism 4 includes a screening bin 44, the outer surface of which is symmetrically provided with a clamping plate 45, the opposite side of the clamping plate 45 is fixedly connected to the outer surface of the screening bin 44, the inner wall of the screening bin 44 is slidably connected with a screening plate 42, the outer surface of the screening plate 42 is symmetrically provided with a spring groove 41, the inner wall of the spring groove 41 is fixedly connected to the outer surface of the screening plate 42, the outer surface of the screening bin 44 is symmetrically provided with a control mechanism 43, the inner wall of the control mechanism 43 is fixedly connected to the outer surface of the screening bin 44, the crystals after being crushed fall into the screening bin 44 through the base 1, and are screened by the screening plate 42 in the screening bin 44, the qualified crystals pass through the screening plate 42, and the unqualified crystals stay on the top of the screening plate 42, the crushed crystals are automatically screened, the tediousness of manual screening is reduced, and the crushing quality is improved.

[0038] The control mechanism 43 includes a bottom plate 431, the inner wall of the bottom plate 431 is rotatably connected to a connecting rod 437, the end of the connecting rod 437 away from the bottom plate 431 is rotatably connected to a sliding rod 434, the outer surface of the sliding rod 434 is fixedly connected to a magnetic ring 436, the top of the magnetic ring 436 is fixedly connected to an adjusting cylinder 435, the outer surface of the sliding rod 434 is slidably connected to a fixing groove 432, the inner wall of the fixing groove 432 is fixedly connected to a magnetic plate 433, the top of the bottom plate 431 is fixedly connected to the bottom of the sieve plate 42, the inner wall of the fixing groove 432 is fixedly connected to the outer surface of the sieve bin 44 The surface is fixedly connected. When the weight on the top of the sieve plate 42 reaches a certain level, the magnetic force between the magnetic plate 433 and the magnetic ring 436 cannot be controlled. The slide rod 434 slides to make the connecting rod 437 drive the sieve plate 42 to rotate. During rotation, the spring groove 41 creates a gap between the sieve plate 42 and the sieve bin 44, ensuring that the sieve plate 42 is opened smoothly and unqualified products are discharged. When the device faces unqualified products and the device opens the protection device, it can guide the crystals to the other side to avoid mixing with qualified finished products. It cooperates with the crushing mechanism 2 to ensure the safe operation of the device.

[0039] When in use, the centrifugal shaft 23 is driven to rotate through the transmission component 5. During the rotation, the centrifugal shaft 23 drives the crushing plate 24 to fluctuate through the surface protrusions during rotation, so that the centrifugal shaft 23 drives the crushing plate 24 to vibrate and fluctuate, and the surface tooth grooves and the adjustment plate 33 are used to crush the passing crystals. At the same time, before crushing, the size of the crushed crystals can be adjusted according to the needs, so that the hydraulic rod 34 pushes the adjustment plate 33 to rotate, and the gap between the hydraulic rod 34 and the crushing plate 24 is changed. At the same time, during the adjustment process, since the leak-proof plate 38 is made of elastic plate, during the adjustment process, the leak-proof plate 38 always keeps in contact with the bottom of the adjustment plate 33 under the action of the top plate 35.

[0040] At the same time, when the crushing starts, the nozzle 7 drives the water in the water tank 6 through the water pump and sprays it into the gap between the adjustment plate 33 and the crushing plate 24, so that the water flow continues to spray during the crushing process of the crystal to ensure the surface is wet.

[0041] During the crushing process, when the crushing plate 24 vibrates, the connecting block 213 drives the slider 215 to rotate, and at the same time, the top block 218 supports the crushing plate 24 on the surface of the crushing plate 24 to ensure that the crushing work of the crushing plate 24 is carried out normally. At the same time, when encountering foreign matter mixed inside the crystal and the strength of the crushing plate 24 is unable to crush it, the curved rod 217 causes the top block 218 to slide through elastic deformation, so that the crushing plate 24 rotates an angle and stops the crushing work.

[0042] When the crushing plate 24 rotates, it pushes the slider 215 to move. When the slider 215 slides, the curved plate 2164 is deformed, allowing the slider 215 to pass. When the slider 215 slides quickly and collides, the elastic block 2161 is used to reduce shock. At the same time, the curved plate 2164 restores its deformation after the slider 215 passes, limiting the sliding of the slider 215.

[0043] After being crushed, the crystals fall into the sieve bin 44 through the base 1 and are screened by the sieve plate 42 in the sieve bin 44. When the crystals fall into the sieve bin 44, the sieve bin 44 is shaken by impact. The shaking caused by continuous falling and impact is used to screen the crystals. The qualified crystals pass through the sieve plate 42, while the unqualified crystals stay on the top of the sieve plate 42. When the weight on the top of the sieve plate 42 reaches a certain level, the magnetic force between the magnetic plate 433 and the magnetic ring 436 cannot be controlled, and the sliding rod 434 slides to make the connecting rod 437 drive the sieve plate 42 to rotate. During the rotation, the elastic groove 41 creates a gap between the sieve plate 42 and the sieve bin 44, thereby ensuring the smooth opening of the sieve plate 42 and the discharge of unqualified products.

[0044] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
