Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically to a solid waste dust removal device for the production of white fused alumina. Background Technology

[0002] White fused alumina is a large crystalline block of corundum formed by melting alumina raw materials in a high-temperature electric furnace at over 2000 degrees Celsius and then cooling and crystallizing them. White fused alumina has extremely high hardness, second only to diamond and silicon carbide. A large amount of white fused alumina dust is generated during the process of crushing large, dense fused alumina blocks into smaller pieces using equipment such as jaw crushers and double roll crushers.

[0003] Existing dust removal equipment typically uses a negative pressure dust collection hood to directly suck in the generated white fused alumina dust. However, due to the extremely high hardness of white fused alumina, the dust sucked into the dust removal equipment will directly impact the internal baffles and other structures, causing extremely severe wear.

[0004] In view of this, the present invention proposes a solid waste dust device for the production of white fused alumina, in order to solve the problems existing in the prior art. Summary of the Invention

[0011] Preferably, a hydraulic bladder is placed inside the inner shell, and a limiting strip is provided on the inner shell corresponding to the inflation end of the hydraulic bladder. The blind end of the hydraulic bladder abuts against a top plate. The center of the top plate is fixedly connected to one end of a push rod. The other end of the push rod slides through the inner shell in a sealed manner and is fixedly connected to a plug. A second spring is sleeved on the outside of the push rod. The two ends of the second spring are fixedly connected to the plug and the outer wall of the inner shell, respectively. The plug can seal a compensation hole opened on the outer end of the oil drain block. A compensation pipe is connected to the outside of the compensation hole, and the compensation pipe is connected to a capillary tube.

[0012] Preferably, the capillary extends upward along the support rod, sealingly passing through the outside of the air intake pipe and connecting to the actuator cylinder. The actuator cylinder is fixedly installed on the outer wall of the buffer box via a connector. A wedge block is fixedly connected to the output end of the actuator cylinder. A support block slides against the bottom of the wedge block. The support block is welded to the outer wall of the buffer box. A first toothed plate is provided on one side of the wedge block. The first toothed plate slides and engages inside the first sliding sleeve. The first sliding sleeve is fixed to the outer wall of the buffer box.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The solid waste dust removal device for producing white fused alumina of the present invention uses a buffer box to allow most of the coarse particles to settle directly by gravity and inertia, which greatly reduces the dust load entering the subsequent pipelines and dust removal mechanism.

[0017] The solid waste dust removal device for producing white fused alumina of the present invention, by setting an induction cylinder and cooperating with a mechanical linkage structure such as damping blades, can adapt to the concentration of dust particles, thereby adjusting the opening and closing angle of the damping blades, further limiting the speed of dust particles, reducing impact damage to the dust removal body, improving service life and reducing maintenance costs.

[0018] The solid waste dust collection device for producing white fused alumina of the present invention, by setting a target head and an internal foldable wing plate structure, enables the wing plate to be unfolded by triggering a corresponding mechanism when the dust particle concentration is high, thereby increasing the projected area of ​​the target plate. Under the condition of high concentration and large particle flow, the total number of particles impacting the target plate per unit time and the total kinetic energy are greatly increased. This directly amplifies the input signal strength of the sensing cylinder, providing a more abundant and reliable power source for subsequent hydraulic amplification and mechanical execution, ensuring that the system can still generate sufficient regulating force under harsh working conditions.

Detailed Implementation

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Please see Figure 1-10 A solid waste dust collection device for producing white fused alumina includes a buffer box 50. An air inlet pipe 10 is connected to the front end of the buffer box 50. A sensing cylinder 30 is installed at the connection between the air inlet pipe 10 and the buffer box 50. A target head 20 is installed at the receiving end of the sensing cylinder 30. The sensing cylinder 30 is connected to an actuating cylinder 60 via a pipeline. The output end of the actuating cylinder 60 is connected to a rotating shaft end of multiple damping blades 70 via multiple sets of gears. The multiple damping blades 70 are rotatably connected inside a connecting pipe 80. One end of the connecting pipe 80 is connected to the air inlet port of the dust collection body 90, and the other end of the connecting pipe 90 is connected to the buffer box 50. By adding a buffer... The buffer box 50 utilizes gravity and inertia to allow most of the coarse particles to settle directly, greatly reducing the dust load entering the subsequent pipelines and dust removal mechanism. It should be noted that the connecting pipe 90 and the air inlet pipe 10 are connected to the two adjacent end faces of the buffer box 50. When the white corundum particles impact the target head 20 of the sensing cylinder 30, the liquid in the sensing cylinder 30 is squeezed into the actuating cylinder 60. The subsequent transmission amplification component drives the rotation and opening and closing of the damping blades 70, thereby reducing the dust flow rate. In this way, the impact of the white corundum particles on the dust removal body 90 is reduced by both the buffer box 50 and the damping blades 70, thereby increasing the service life of the dust removal equipment.

[0033] Please see Figure 3-7The upper and lower outer wall end faces of the sensing cylinder 30 are fixedly connected to the inner wall of the air intake pipe 10 through the support rod 34. The sensing shaft 31 of the sensing cylinder 30 is fixedly connected to the target head 20. A first spring 33 is sleeved on the outside of the sensing shaft 31. The two ends of the first spring 33 are fixedly connected to the end face of the sensing cylinder 30 and the rear end face of the target head 20, respectively. The first spring 33 can drive the target head 20 and subsequent structures to reset. The rear end of the target head 20 is cylindrical and hollow and is slidably sleeved on the front end of the sensing cylinder 30. The sensing cylinder 30 is symmetrically fixed on both sides of the sensing shaft 31 with inclined blocks 32. When dust passes through the air intake pipe 10, it will continuously hit the target head 20. The target head 20 drives the sensing shaft 31 to move backward and compress the hydraulic oil in the sensing cylinder 30.

[0034] Please see Figure 6-7 The target head 20 has a groove inside its front end and a turntable 24 is rotatably connected to it. The front end of the turntable 24 is hinged to one end of multiple connecting rods 23, and the other end of the connecting rods 23 is hinged to the inner corner of the wing plate 22. It should be noted that the connecting rods 23 are initially in an offset state and gradually move towards the diameter line of the turntable as the turntable 24 rotates. The outer far end of the wing plate 22 is rotatably connected to the groove in the target head 20. The target plate 21 is installed at the front end of the target head 20 by screws. The two ends of the peripheral wall of the turntable 24 are rotatably connected to transmission balls 25. The rear side of the transmission balls 25 has a through hole 26 corresponding to the position of the inclined block 32, which allows the inclined block to pass through. When the dust particles are large, the impact on the target head 20 is reduced. The increased size of the target plate 21 compresses the larger displacement of the sensing shaft 31, causing the inclined block 32 to pass through the through hole 26 and abut against the transmission ball 25. The transmission ball 25 then rolls along the inclined surface of the inclined block 32, thereby driving the turntable 24 to rotate. The connecting rod 23 rotates around the hinge point, pushing the wing plate 22 out of the groove of the target head 20. This significantly increases the projected area of ​​the target plate 21. Under high-concentration, large-particle flow conditions, the total number of particles impacting the target plate per unit time and the total kinetic energy increase significantly. This directly amplifies the input signal strength of the sensing cylinder 30, providing a more abundant and reliable power source for subsequent hydraulic amplification and mechanical execution, ensuring that the system can still generate sufficient regulating force under harsh conditions.

[0035] Please see Figure 4-5 The rear end of the sensing cylinder 30 is fixedly connected to an oil discharge end block 40. The oil discharge end block 40 is provided with a throttling orifice 41 and a compensation chamber 42. The outside of the throttling orifice 41 is connected to a throttling tube 411. It should be noted that the diameter of the throttling orifice 41 is smaller than the diameter of the capillary tube 49. The throttling tube 411 is connected to the capillary tube 49. The compensation chamber 42 is provided with an inner shell 43. The outer corner of the inner shell 43 is fixedly connected to the inner corner wall of the compensation chamber 42. A gap 421 is left between the compensation chamber 42 and the inner shell 43. The hydraulic oil in the sensing cylinder 30 can enter the compensation chamber 42 through the gap 421.

[0036] Please see Figure 4-5The inner shell 43 contains a hydraulic bladder 44. The hydraulic bladder 44 acts as a buffer when a single large particle impacts the target plate 21, preventing accidental triggering of the sensing cylinder 30. Subsequent operation is only performed when a continuous stream of large particles impacts the target plate 21. A limiting strip 431 is provided at the inflation end of the inner shell 43 corresponding to the hydraulic bladder 44. The blind end of the hydraulic bladder 44 abuts against a top plate 45. The center of the top plate 45 is fixedly connected to one end of a push rod 46. The other end of the push rod 46 slides through the inner shell 43 and is fixedly connected to a plug 48. A second spring 47 is sleeved on the outside of the push rod 46. Both ends of the second spring 47 are fixedly connected to the plug 48 and the outer wall of the inner shell 43, respectively. The plug 48 can seal against the oil drain block 40. A compensation hole 422 is opened at the outer end, and a compensation pipe 4221 is connected to the outer side of the compensation hole 422. The compensation pipe 4221 is connected to the capillary tube 49. By using the capillary tube 49, the movement stroke of the sensing cylinder 30 can be amplified. When the external particle concentration is large, the pressure inside the sensing cylinder 30 increases, which in turn squeezes the hydraulic bladder 44 to reduce its volume and lose its limiting effect on the top plate 45. Under the action of the second spring 47, the plug 48 is released from the blockage of the compensation hole 422, and the hydraulic oil in the compensation chamber 42 enters the compensation pipe 4221 through the compensation hole 422 and finally flows into the capillary tube 49, increasing the oil volume in the capillary tube 49 and further amplifying the displacement path of the actuator cylinder 60.

[0037] Please see Figure 3-10 The capillary tube 49 extends upward along the support rod, sealingly passing through the outside of the air intake pipe 10 and connecting to the actuator cylinder 60. The actuator cylinder 60 is fixedly installed on the outer wall of the buffer box 50 through a connector. A wedge block 61 is fixedly connected to the output end of the actuator cylinder 60. It should be noted that the slope of the top of the wedge block 61 is relatively gentle to increase the upward displacement force of the first toothed plate 63. The bottom of the wedge block 61 slides against a support block 62, which is welded to the outer wall of the buffer box 50. A first toothed plate 63 is provided on one side of the wedge block 61. The first toothed plate 63 is slidably engaged inside the first sliding sleeve 64, which is fixed to the outer wall of the buffer box 50. The bottom of the first toothed plate 63 has a slope structure that can cooperate with the wedge block 61 to slide against it. When the hydraulic oil pushes the actuator cylinder 60, the output end of the actuator cylinder 60 drives the wedge block 61 to move, thereby abutting against the bottom slope end of the first toothed plate 63 and pushing the first toothed plate 63 upward.

[0038] Please see Figure 9The toothed structure of the first toothed plate 63 is meshed with one side of the first gear 65, and the other side of the first gear 65 is meshed with the second gear 66. The second gear 66 is coaxially fixed with the third gear 67. The rotating shafts on both sides of the first gear 65, the second gear 66 and the third gear 67 are fixed by the support frame 68. The legs of the support frame 68 are fixed to the outer wall of the buffer box 50. It should be noted that the diameter of the first gear 65 is much larger than the diameter of the second gear 66, which makes the first gear 65 rotate a smaller angle while the second gear 66 rotates a larger angle, further increasing the subsequent mechanical movement stroke.

[0039] Please see Figure 8-9 The third gear 67 is meshed with the second gear plate 72. The second gear plate 72 is slidably engaged inside the second sliding sleeve 73. The second sliding sleeve 73 is fixed inside the buffer box 50. Multiple sets of fourth gears 71 are meshed on one side of the second gear plate 72. The central shaft of the fourth gear 71 is fixed to the rotating shaft of the damping blade 70. The up and down displacement of the second gear plate 72 can drive the multiple sets of fourth gears 71 to rotate, thereby causing the damping blade 70 to rotate accordingly, thus controlling the dust conveying speed.
