Description
TECHNICAL FIELD

[0002] Fumed silica, also known as fumed silica, is a kind of extremely fine nanometer amorphous silica with small particle size, uniform particle size distribution and large specific surface area, and has high surface activity. It is widely used in high polymer composite materials, silicone rubber, paint, electronic packaging materials, gel storage battery, ceramics, plastics, glass steel, sealant, papermaking, food, cosmetics, gelatin resin, chemical mechanical polishing, etc. It can play the role of reinforcement, thickening, thixotropy and extinction. After the production of fumed silica is completed, it needs to be uniformly conveyed to the vacuum packaging machine after being stored in the bin. However, the powder will arch in the bin during conveying, so the bin conveying device needs to have the function of breaking arch and discharging.
[0003] When the powder accumulated in the large bin is more, the weight of the powder in the bin will press on the stirring structure of the traditional arch breaker. When stirring, the stirring structure will contact with a large amount of powder, which will generate a large resistance. Therefore, a large torque is needed when the arch breaker is started. The output of the large torque and the resistance and pressure received by the stirring structure will not only cause the stirring structure to appear fatigue wear, deformation and even breakage due to overloading stress for a long time, but also cause the driving motor of the arch breaker to be in high load working condition for a long time, which will cause the motor to heat seriously and the energy consumption to increase sharply, thereby affecting the arch breaking effect and service life of the device.
[0004] Therefore, the present application provides a fumed silica powder bin arch breaking and discharging conveying device to meet the needs. SUMMARY

[0016] Compared with the prior art, the present application has at least the following advantages: In the above scheme, the first and second arch breaking mechanisms are used to pre-break the arch at the edge and middle of the conveying chamber, respectively, to reduce the arching degree of the powder in the conveying chamber when the arching of the powder in the conveying chamber is serious, and to improve the looseness of the powder in the conveying chamber. When the edge arch breaking rod rotates, it will slide in the arc-shaped slot. When the edge arch breaking rod moves to the other end of the arc-shaped slot and abuts against the inner wall, it will drive the rotating convex ring to rotate synchronously on the convex ring bearing, thereby driving the turnover arch breaking knife to rotate in the conveying chamber. The turnover arch breaking knife stirs and breaks the arch of the powder in the conveying chamber on a large scale. In this way, the turnover arch breaking knife with a large contact area with the powder in the conveying chamber is not directly driven to rotate, thereby avoiding the problem that the turnover arch breaking knife is subjected to excessive torque, resistance and pressure, which causes the turnover arch breaking knife to be subjected to fatigue wear, deformation and even breakage for a long time. The motor is prevented from being subjected to high load for a long time, thereby avoiding the problems of serious heating and rapid increase of energy consumption. The arch breaking effect and service life of the device are improved.
[0017] When the edge arch breaking rod rotates in the arc-shaped slot, the roller abutting rod abuts against the inclined surface of the slope bottom protrusion, thereby applying downward pressure to the edge arch breaking rod, causing the threaded connecting rod to slide downward, the sliding frame to slide downward synchronously in the connecting groove, and the reset spring ring to be compressed. Due to the inclination of the edge arch breaking rod and the elasticity of the spring strip, the sliding frame slides in the sliding connecting block when the edge arch breaking rod presses the threaded connecting rod to descend, thereby pushing the second arch breaking mechanism to move towards the center. The middle arch breaking rod moves radially with the second arch breaking mechanism, thereby further covering the arching area in the middle of the conveying chamber. The extension rods of the multiple second arch breaking mechanisms have different lengths, which cooperate with the above-mentioned mode during rotation without the need for additional increase in driving load to continuously maintain a low-resistance arch breaking state, thereby greatly improving the pre-arch breaking effect of the first and second arch breaking mechanisms.
[0018] When the edge arch breaking rod descends, the arch breaking auxiliary mechanism descends synchronously, thereby enabling the pressing strip and the movable push plate to press the powder inside the conveying chamber, thereby further improving the arch breaking effect. The elastic part is arranged on the pressing strip, which can elastically deform when the movable push plate is blocked, thereby preventing the pressing strip from being broken. The movable push plate is rotationally connected to the connecting part. When the bottom of the movable push plate is pressed, the movable push plate rotates on the connecting part. The top of the movable push plate abuts against the limiting inclined surface, thereby enabling the movable push plate to assume an inclined posture in the rotation direction of the top connecting frame, thereby further improving the arch breaking effect and reducing the arch breaking dead angle.

[0027] As Figures 1 to 10As shown, the embodiment of the present application provides a white carbon black powder bin arch breaking and discharging conveying device, which comprises a conveying bin body 1 and a driving mechanism 2 installed at the bottom of the conveying bin body 1. The driving mechanism 2 comprises a rotating discharging cylinder 204 connected at the outlet of the conveying bin body 1. A plurality of connecting blocks 208 are fixedly arranged on the inner wall of the rotating discharging cylinder 204. The driving mechanism 2 further comprises an upper connecting ring 201 fixedly arranged at the bottom of the conveying bin body 1. The bottom of the upper connecting ring 201 is fixedly connected with a lower connecting ring 202 through bolts. The upper connecting ring 201 is rotatably connected with the lower connecting ring 202 through a main rotating gear 203. The inner wall of the main rotating gear 203 is fixedly connected with the rotating discharging cylinder 204. The rotating discharging cylinder 204 is rotatably connected with the outlet of the conveying bin body 1. A gear connecting frame 205 is fixedly connected between the upper connecting ring 201 and the lower connecting ring 202 through bolts. A connecting gear 206 is rotatably connected inside the gear connecting frame 205. A motor 207 is fixedly arranged at the top of the gear connecting frame 205. A main drive gear is rotatably arranged at the output end of the motor 207 and fixedly arranged at a position inside the gear connecting frame 205. The main drive gear is engaged with the connecting gear 206. The connecting gear 206 is engaged with the main rotating gear 203. The connecting gear 206 is driven to rotate inside the gear connecting frame 205 through the main drive gear of the motor 207. The main rotating gear 203 is synchronously rotated through the engagement between the connecting gear 206 and the main rotating gear 203, so as to drive the rotating discharging cylinder 204 to rotate, and the edge arch breaking rod 308 of the primary arch breaking mechanism 3 is rotated at the edge of the conveying bin body 1. The inner wall of the rotating discharging cylinder 204 is provided with a plurality of primary arch breaking mechanisms 3 for pre-breaking the arch at the edge of the conveying bin body 1. The primary arch breaking mechanism 3 comprises a threaded connecting rod 301 detachably arranged on the top of the connecting block 208. A sliding connecting block 304 is fixedly arranged on the top of the threaded connecting rod 301. A sliding frame 306 is arranged inside the sliding connecting block 304. A spring strip 307 is fixedly arranged on the top of the sliding frame 306. An edge arch breaking rod 308 is fixedly arranged on the top of the spring strip 307. The edge arch breaking rod 308 is an elongated circular rod. The edge arch breaking rod 308 is in the shape of an elongated circular arc, which reduces the resistance generated by the contact between the edge arch breaking rod 308 and the powder in the conveying bin body 1 during arch breaking. Thus, the edge of the conveying bin body 1 is subjected to primary arch breaking. A connecting groove 209 is formed on the top of the connecting block 208. The threaded connecting rod 301 is slidably arranged through the top of the connecting block 208. A nut for limiting the threaded connecting rod 301 is threadedly connected with the threaded connecting rod 301. A pressing sliding frame 302 is fixedly arranged on the outer wall of the threaded connecting rod 301 and slidably connected with the connecting groove 209. A reset spring ring 303 is fixedly arranged on the inner wall at the bottom of the connecting groove 209. The bottom of the pressing sliding frame 302 abuts against the reset spring ring 303. The sliding frame 306 is provided with a two-stage arch breaking mechanism 4 for pre-breaking the arch in the middle of the conveying bin body 1, which cooperates with the first-stage arch breaking mechanism 3 to pre-break the arch of the white carbon black powder in the conveying bin body 1. The top of the sliding connecting block 304 is provided with a sliding hole 305, and the connecting end of the sliding frame 306 and the spring strip 307 is in sliding connection with the sliding hole 305. The two-stage arch breaking mechanism 4 comprises an extension rod 401 fixed on the side of the sliding frame 306 away from the sliding connecting block 304, and a middle arch breaking rod 402 fixed on the top of the extension rod 401. The width of the middle arch breaking rod 402 is the same as the diameter of the edge arch breaking rod 308, and the cross section of the middle arch breaking rod 402 is in the shape of a cross. While the edge arch breaking rod 308 rotates, it is connected with the sliding frame 306 through the extension rod 401, so as to break the arch in the middle of the conveying bin body 1. Since the middle arch breaking rod 402 in the middle of the conveying bin body 1 is subjected to a smaller pressure than the edge arch breaking rod 308, the cross section of the middle arch breaking rod 402 is in the shape of a cross while its width is similar to that of the edge arch breaking rod 308, so as to improve the arch breaking effect. The outer wall of the edge arch breaking rod 308 is fixed with an enclosed sleeve 309 on the top of the sliding connecting block 304, the enclosed sleeve 309 is made of flexible material, which prevents the powder from being stuck in the sliding hole 305. The delay rotating mechanism 6 further comprises a plurality of slope bottom protrusions 601 fixed on the bottom of the rotating convex ring 502, and the number of the slope bottom protrusions 601 is the same as that of the arc-shaped strip holes 602. The arc-shaped strip holes 602 penetrate the slope bottom protrusions 601. The outer wall of the edge arch breaking rod 308 is fixed with a roller abutting rod 603, and the roller part on the roller abutting rod 603 abuts against the slope surface on the bottom of the slope bottom protrusion 601. During the rotation of the edge arch breaking rod 308 in the arc-shaped strip hole 602, the roller abutting rod 603 abuts against the slope surface of the slope bottom protrusion 601, so as to exert a downward pressure on the edge arch breaking rod 308, so that the threaded connecting rod 301 penetrates the connecting block 208 and slides downward, the sliding frame 302 is pressed and synchronously slides downward in the connecting groove 209, and the reset spring ring 303 is compressed. Due to the inclined arrangement of the edge arch breaking rod 308 and the elasticity of the spring strip 307, when the edge arch breaking rod 308 presses the threaded connecting rod 301 to descend, the sliding frame 306 slides in the sliding connecting block 304, pushing the two-stage arch breaking mechanism 4 to move towards the center, so that the middle arch breaking rod 402 further covers the arched area in the middle of the conveying bin body 1 through the radial movement of the two-stage arch breaking mechanism 4. The lengths of the extension rods 401 in the plurality of two-stage arch breaking mechanisms 4 are different, which cooperate with the above-mentioned mode during rotation, so as to greatly improve the pre-arch breaking effect of the first-stage arch breaking mechanism 3 and the two-stage arch breaking mechanism 4 without increasing the driving load, thereby maintaining a low-resistance arch breaking state. The top of the conveying bin body 1 is provided with a main arch breaking mechanism 5 for driving the main arch breaking structure to rotate, the main arch breaking mechanism 5 comprises a convex ring bearing 501 fixed on the inner wall of the conveying bin body 1, the outer wall of the convex ring bearing 501 is rotationally connected with a rotating convex ring 502, the outer wall of the rotating convex ring 502 is fixed with the main arch breaking structure, the top of the conveying bin body 1 is detachably and fixedly connected with a limiting sleeve frame 504, the limiting sleeve frame 504 is used for limiting the rotating convex ring 502 installed on the convex ring bearing 501, the main arch breaking structure is a plurality of material turning arch breaking knives 503 fixed on the outer wall of the rotating convex ring 502, the outer wall of the material turning arch breaking knife 503 is attached to the inner wall of the conveying bin body 1, and the surface away from the inner wall of the conveying bin body 1 is a curved surface, the bottom of the main arch breaking mechanism 5 is provided with a delay rotation mechanism 6 for delaying driving the material turning arch breaking knife 503 to rotate, the delay rotation mechanism 6 comprises an arc-shaped strip hole 602 penetratingly provided on the rotating convex ring 502, and the edge arch breaking rod 308 is slidingly connected with the arc-shaped strip hole 602, the conveying bin body 1 is pre-arch broken at the edge and the middle by the first arch breaking mechanism 3 and the second arch breaking mechanism 4 respectively, when the powder in the conveying bin body 1 is seriously arch broken, the arch breaking degree of the powder is reduced, and the looseness of the powder in the conveying bin body 1 is improved, when the edge arch breaking rod 308 rotates, it will slide in the arc-shaped strip hole 602, when the edge arch breaking rod 308 moves to the other end and abuts against the inner wall of the arc-shaped strip hole 602, it will drive the rotating convex ring 502 to rotate synchronously on the convex ring bearing 501, so as to drive the material turning arch breaking knife 503 to rotate in the conveying bin body 1, the powder in the conveying bin body 1 is widely stirred and broken by the material turning arch breaking knife 503, so that in this way, when the arch is broken, the material turning arch breaking knife 503 with a large contact area with the powder in the conveying bin body 1 is directly driven to rotate, the material turning arch breaking knife 503 is prevented from being directly subjected to a large torque output and the resistance and pressure of the stirring structure, so that the material turning arch breaking knife 503 is prevented from being subjected to fatigue wear, deformation and even fracture for a long time due to overloading stress, and the motor 207 is prevented from being in a high load working condition for a long time to cause serious heating and a sharp increase in energy consumption.
[0028] As Figure 4 , Figure 5 and Figure 8As shown, the plurality of edge arch breaking rods 308 are provided with an arch breaking auxiliary mechanism 7 on the top, the arch breaking auxiliary mechanism 7 comprises a top connecting frame 701 fixedly arranged on the top of the plurality of edge arch breaking rods 308, a plurality of pressing strips 702 are fixedly connected to the outer wall of the top connecting frame 701, the pressing strips 702 are sequentially divided into elastic portions 703 and connecting portions 704 from top to bottom, the bottom of the connecting portion 704 is a limiting inclined surface 706, a movable actuating plate 705 is rotatably connected to the bottom of the connecting portion 704, and the top of the movable actuating plate 705 abuts against the limiting inclined surface 706; when the edge arch breaking rod 308 is lowered, the arch breaking auxiliary mechanism 7 is lowered synchronously, so that the pressing strip 702 and the movable actuating plate 705 can perform a pressing action inside the powder, further improving the arch breaking effect; by arranging the elastic portion 703 on the pressing strip 702, when the movable actuating plate 705 is blocked when pressed, the elastic portion 703 can be elastically deformed, avoiding the phenomenon that the pressing strip 702 is broken; by rotatably connecting the connecting portion 704 and the movable actuating plate 705, when the bottom of the movable actuating plate 705 is pressed, the movable actuating plate 705 can rotate on the connecting portion 704, the top of the movable actuating plate 705 abuts against the limiting inclined surface 706, so that the movable actuating plate 705 assumes an inclined posture in the rotating direction of the top connecting frame 701, so that the arch breaking effect can be further improved by the inclined posture of the movable actuating plate 705.
[0029] The technical scheme provided by the application has the following working principle: The main drive gear on the motor 207 drives the connecting gear 206 to rotate inside the gear connecting frame 205, and through the meshing of the connecting gear 206 and the main rotating gear 203, the main rotating gear 203 rotates synchronously, thereby driving the rotating discharge cylinder 204 to rotate, and the edge arch-breaking rod 308 of the first arch-breaking mechanism 3 rotates at the edge of the conveying bin body 1. The edge arch-breaking rod 308 is in the shape of an elongated arc, which reduces the resistance generated by the contact between the edge arch-breaking rod 308 and the powder in the conveying bin body 1 during arch breaking, thereby performing first arch breaking at the edge of the conveying bin body 1. While the edge arch-breaking rod 308 rotates, the middle arch-breaking rod 402 in the middle of the conveying bin body 1 can be broken arch by connecting the extension rod 401 and the sliding frame 306. Since the middle arch-breaking rod 402 in the middle of the conveying bin body 1 is subjected to less pressure than the edge arch-breaking rod 308, the cross-sectional width of the middle arch-breaking rod 402 can be designed as a cross shape while being similar to that of the edge arch-breaking rod 308, thereby facilitating the improvement of the arch-breaking effect. The first arch-breaking mechanism 3 and the second arch-breaking mechanism 4 respectively pre-arch the edge and the middle of the conveying bin body 1. When the powder in the conveying bin body 1 is severely arching, the degree of arching of the powder is reduced, and the bulkiness of the powder in the conveying bin body 1 is improved. When the edge arch-breaking rod 308 rotates, it will slide in the arc-shaped slot hole 602. When the edge arch-breaking rod 308 moves to the other end and abuts against the inner wall of the arc-shaped slot hole 602, it will drive the rotating convex ring 502 to rotate synchronously on the convex ring bearing 501, thereby driving the turnover arch-breaking knife 503 to rotate in the conveying bin body 1. The turnover arch-breaking knife 503 stirs and breaks the powder in the conveying bin body 1 in a large range, thereby avoiding directly driving the turnover arch-breaking knife 503 with a large contact area with the powder in the conveying bin body 1 to rotate during arch breaking, avoiding the turnover arch-breaking knife 503 being subjected to a large torque output and the resistance and pressure of the stirring structure, thereby causing the turnover arch-breaking knife 503 to be subjected to overloading stress for a long time, resulting in fatigue wear, deformation, or even breakage, and avoiding the motor 207 being in a high-load working condition for a long time, resulting in serious heating and a sharp increase in energy consumption. When the edge breaking arch rod 308 rotates inside the arc-shaped hole 602, the roller resistance rod 603 will be in contact with the slope of the slope bottom bump 601, thereby exerting downward pressure on the edge breaking arch rod 308, causing the threaded connecting rod 301 to slide down through the connecting block 208, pressing the sliding frame 302 to slide down synchronously in the connecting groove 209, and compressing the reset spring ring 303. Through the inclined arrangement of the edge breaking arch rod 308 and the elasticity of the spring strip 307, when the edge breaking arch rod 308 presses the threaded connecting rod 301 to descend, the sliding frame 306 will slide inside the sliding connecting block 304, pushing the secondary arch breaking mechanism 4 to move towards the center, so that the middle arch breaking rod 402 further covers the middle arch area of the conveying bin body 1 through the radial movement of the secondary arch breaking mechanism 4, and through the different lengths of the extension rods 401 of the multiple secondary arch breaking mechanisms 4, the above-mentioned mode is cooperated during rotation, without the need to increase the driving load, the effect of pre-breaking arch of the primary arch breaking mechanism 3 and the secondary arch breaking mechanism 4 is greatly improved.
[0030] When the edge breaking arch rod 308 descends, it will drive the arch breaking auxiliary mechanism 7 to descend synchronously, so that the pressing strip 702 and the movable toggle plate 705 can perform pressing action inside the powder, further improving the arch breaking effect. By providing an elastic part 703 on the pressing strip 702, when the movable toggle plate 705 is pressed and blocked, the elastic part 703 can produce elastic deformation, avoiding the phenomenon of breaking of the pressing strip 702. The connecting part 704 is rotationally connected with the movable toggle plate 705, when the bottom of the movable toggle plate 705 is pressed, the movable toggle plate 705 can rotate on the connecting part 704, the top of the movable toggle plate 705 is in contact with the limiting slope 706, and the movable toggle plate 705 assumes an inclined posture in the rotation direction of the top connecting frame 701, so that the arch breaking effect can be further improved through the inclined posture of the movable toggle plate 705.
