Description

Technical Field

[0001] This invention relates to the field of silo arch breaking technology, specifically to a silo rotary vibration arch breaking device. Background Technology

[0002] Industrial by-product gypsum (phosphogypsum, titanium gypsum, desulfurization gypsum, etc.), red mud, and other general industrial solid wastes are characterized by high moisture content, small particle size, and high viscosity. During comprehensive utilization, the material tends to form dome-shaped arches when entering and exiting the silo, preventing downward flow and hindering normal output. How to break these arches to allow for smooth material output is a prerequisite for the large-scale comprehensive utilization and disposal of such general industrial solid wastes. Currently, arch-breaking devices for traditional materials mainly include stirring arch-breaking, vibration arch-breaking, and pneumatic arch-breaking methods.

[0003] For example, Chinese invention patent No. 201310526009.1 provides a silo arch-breaking device. In use, the device uses clamping wheels to clamp the arch-breaking rod, and the clamping wheels rotate to drive the arch-breaking rod through the through hole set on the silo wall to enter the silo for rotational arch breaking. This solves the technical problem that the material cannot be sent out of the silo normally due to arching, thus affecting the normal functioning of the silo.

[0004] For example, Chinese patent number 202021217806.3 provides a hopper vibration arch-breaking device. When in use, the device drives the hopper to vibrate through a vibration mechanism. The arch-breaking cone vibrates with the vibration of the hopper, thereby breaking up the material that has formed an arch, thus avoiding the problem of material transportation being obstructed after the material forms an arch in the hopper.

[0005] For example, Chinese patent number 201922159870.4 provides a pneumatic blasting arch-breaking device. When arching occurs in the silo, the device uses a hydraulic cylinder to drive a gate to send a compressed air tank below the silo opening and to feed compressed air into the tank. When the pressure of the compressed air reaches the rated pressure, the rupture disc installed on the cover plate bursts, and the compressed air is rapidly ejected from the rupture hole, generating a strong air impact on the arched material in the silo from below, thus achieving the purpose of breaking the arch.

[0006] However, phosphogypsum powder is more viscous than traditional materials, making it more prone to arching and sticking to the material walls above the discharge port during feeding. Therefore, it is necessary to improve the arch-breaking location and mechanism, allowing the arch-breaking device to penetrate deep into the material for continuous arch breaking, thereby improving discharge efficiency. Most of the aforementioned patents and traditional arch-breaking devices only use a single method for arch breaking, failing to combine the advantages of multiple traditional arch-breaking devices to simultaneously achieve deep and continuous arch breaking of highly viscous phosphogypsum materials. Therefore, the arch-breaking effect is poor, making it difficult to meet the requirement of smooth phosphogypsum feeding. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention proposes a silo rotary vibration arch-breaking device to solve the technical problem mentioned in the background section: traditional arch-breaking devices are ineffective in breaking up phosphogypsum, making it difficult to achieve smooth material discharge. By designing special connecting parts to form a multi-component collaborative arch-breaking technique, a smoother material discharge effect compared to traditional silos is achieved.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a silo rotary vibration arch-breaking device, comprising:

[0009] The outer shell is connected to the discharge port of the hopper. A detachable inner shell is provided inside the outer shell. A support frame is provided on the inner shell. The cross-section of the inner shell is in the shape of an inverted trapezoid.

[0010] A drive shaft is disposed within the inner shell, and multiple sets of mounting sleeves are arranged at intervals along its axis on the drive shaft, and multiple sets of arch breakers are arranged circumferentially on the mounting sleeves.

[0011] A drive mechanism, disposed on the inner housing and connected to the drive shaft, drives the drive shaft to rotate along its axis and to vibrate the drive shaft; and

[0012] A first vibration component is mounted on the drive shaft and connected to the inner shell. During rotation and vibration, the drive shaft drives the inner shell to vibrate via the first vibration component.

[0013] In a preferred embodiment, the drive mechanism includes:

[0014] The first frame is fixedly mounted on the inner shell;

[0015] A first Reuleaux triangle is disposed at one end of the drive shaft and coaxially connected thereto. The first Reuleaux triangle is disposed within the first frame and fits against the inner wall.

[0016] The drive motor is mounted on a support frame on the inner shell, and the output shaft of the drive motor is provided with a cross coupling. The output shaft of the cross coupling is eccentrically connected to the first Reuleaux triangle block.

[0017] In a preferred embodiment, a first limiting frame is fixedly disposed on the inner shell, a first square is fixedly disposed on the first limiting frame, a second limiting frame is fixedly disposed on the first square, and both the first limiting frame and the second limiting frame are provided with limiting stops.

[0018] In a preferred embodiment, the other end of the drive shaft is provided with a coaxially connected and detachable second Reuleaux block, and the inner wall of the inner shell is provided with a second frame, the second Reuleaux block being engaged in the second frame and fitting against the inner wall.

[0019] In a preferred embodiment, the first vibration component includes:

[0020] An elastic ring is fitted onto the drive shaft;

[0021] Impact ring, fitted onto the elastic ring; and

[0022] Two sets of receiving frames are arranged opposite each other and fixedly mounted on the inner shell. The receiving frames are L-shaped, and the impact ring is disposed between the two sets of receiving frames.

[0023] In a preferred embodiment, limit rings are provided on both sides of the impact ring, the impact ring is in contact with the limit rings, and the limit rings are sleeved on the drive shaft and fixedly connected to it.

[0024] In a preferred embodiment, the inner shell is further provided with a second vibration component, which is connected to the output shaft of the drive motor. When the output shaft of the drive motor rotates, the inner shell is vibrated by the second vibration component.

[0025] In a preferred embodiment, the second vibration component includes:

[0026] A drive disk is mounted on the output shaft of the drive motor, and a drive column is mounted on the drive disk;

[0027] A mounting rod is provided on the inner shell, and a limit plate and a limit block are provided on the mounting rod;

[0028] A mounting ring is slidably fitted onto the mounting rod and located between the limiting plate and the limiting block. The mounting ring is provided with a mounting plate, which includes a wedge-shaped block and an impact post. During the rotation of the drive disc, the mounting ring slides on the mounting rod via the engagement of the drive post and the inclined surface of the wedge-shaped block.

[0029] An elastic element is disposed between the mounting ring and the limiting plate.

[0030] In a preferred embodiment, the support frame is provided with a groove for the drive disc to rotate.

[0031] In a preferred embodiment, the bottom of the housing is provided with a support base, and multiple sets of the support bases are provided, with the feeding device disposed between the multiple sets of the support bases.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In operation, the material in the hopper enters the inner shell for feeding. During feeding, the drive mechanism controls the rotation of the transmission shaft, which in turn drives multiple sets of arch breakers to rotate, breaking up the powder and improving the efficiency of powder conveying. Furthermore, the drive shaft's rotation can be controlled by the drive mechanism to vibrate, thereby driving the arch breakers to vibrate and enhancing the arch-breaking effect. The drive shaft's movement also drives the inner shell to vibrate through the first vibration component, further improving the arch-breaking effect and achieving multiple arch-breaking objectives. This effectively prevents phosphogypsum from accumulating and forming arches inside the inner shell during feeding, thus improving feeding efficiency.

[0034] 2. During operation, the drive motor rotates the drive disc during startup. As the drive disc rotates, the drive column and wedge block work together to slide the mounting ring and mounting plate along the axis of the mounting rod, simultaneously compressing the elastic element and causing the impact column to disengage from the inner shell. The drive disc continues to rotate until the drive column disengages from the wedge block. The elastic element's restoring ability causes the impact column to strike the inner shell, further vibrating it and enhancing the arch-breaking effect. Furthermore, the vibration direction of the second vibration component intersects with that of the first vibration component, resulting in an even better arch-breaking effect.

[0035] 3. The drive motor serves as the power source, enabling arch breaking through rotation, arch breaking through vibration, and arch breaking through vibration by the vibration component striking the inner shell. One power source achieves the synergy of multiple arch breaking methods, which simplifies the structure and improves the arch breaking effect. Attached Figure Description

[0052] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0053] Example:

[0054] like Figure 1As shown, the present invention provides a silo rotation vibration arch breaking device, including an outer shell 101, which is connected to the silo outlet. A detachable inner shell 103 is provided inside the outer shell 101. A support frame 104 is provided on the inner shell 103. The cross-section of the inner shell 103 is inverted trapezoidal. A support seat 102 is provided at the bottom of the outer shell 101. Multiple sets of support seats 102 are provided. A feeding device is provided between the multiple sets of support seats 102.

[0055] In use, the material in the hopper enters the inner shell 103, and the inner shell 103, which is in the shape of an inverted trapezoid, enters the feeding device. The outer shell 101 is supported by the support seat 102, which improves the load-bearing capacity of the device.

[0056] like Figures 1 to 4 As shown, in this embodiment, a drive shaft 401 is provided inside the inner shell 103. Multiple sets of mounting sleeves 403 are arranged at intervals along the axis of the drive shaft 401. Multiple sets of arch breakers 404 are arranged circumferentially on the mounting sleeves 403. A drive mechanism is also provided on the inner shell 103. The drive mechanism drives the drive shaft 401 to rotate along its axis and vibrate. The drive mechanism includes a first square frame 304 fixedly installed on the inner shell 103. A first Reuleaux triangular block 402 is coaxially connected to one end of the drive shaft 401. The first Reuleaux triangular block 402 is located inside the first square frame 304 and fits against the inner wall. A support frame 201 is provided on the inner shell 103. A drive motor 501 is provided on the support frame 201. A cross coupling 504 is provided on the output shaft of the drive motor 501. The output shaft of the cross coupling 504 is eccentrically connected to the first Reuleaux triangular block 402.

[0057] The drive motor 501 can start and drive the endpoint of the first Reuleaux triangular block 402 to move along a square trajectory through the cross coupling 504. During the rotation of the first Reuleaux triangular block 402, it is limited by the inner wall of the first square 304, thereby driving the transmission shaft 401 to reciprocate within a certain range during the rotation. During the rotation of the transmission shaft 401, it can drive the arch breaker 404 to rotate to break the arch. During the rotation of the transmission shaft 401, it can not only expand the arch breaking range, but also drive the arch breaker 404 to generate a certain vibration on the inner shell 103, so as to improve the arch breaking effect.

[0058] like Figure 5As shown, in this embodiment, a first limiting frame 302 is fixedly mounted on the inner shell 103, a first square frame 304 is fixedly mounted on the first limiting frame 302, and a second limiting frame 301 is fixedly mounted on the first square frame 304. Limiting brackets 303 are provided on both the first limiting frame 302 and the second limiting frame 301. The movement range of the first Reuleaux block 402 is limited by the cooperation of the two sets of limiting brackets 303, preventing the first Reuleaux block 402 from deflecting along the axis of the drive shaft 401 and disengaging from the first square frame 304, thus improving the stability of the internal structure of the arch-breaking device.

[0059] like Figure 3 , 4 As shown, in this embodiment, a second Reuleaux block 408, coaxially connected and detachable, is provided at the other end of the drive shaft 401. A second square frame 105 is provided on the inner wall of the inner shell 103, and the second Reuleaux block 408 is engaged within the second square frame 105 and fits against the inner wall. The cooperation between the second Reuleaux block 408 and the second square frame 105 supports the other end of the drive shaft 401, preventing uneven stress on the drive shaft 401 and thus avoiding deformation or breakage, thereby improving the service life of the device.

[0060] like Figure 3 , 4 As shown in Figures 7 and 8, in this embodiment, a first vibration assembly connected to the inner shell 103 is provided on the drive shaft 401. During the rotation and vibration of the drive shaft 401, the inner shell 103 is driven to vibrate through the first vibration assembly. The first vibration assembly includes an elastic ring 405 sleeved on the drive shaft 401, an impact ring 406 sleeved on the elastic ring 405, and two sets of oppositely arranged support frames 106 are provided on the inner shell 103. The support frames 106 are L-shaped, and the impact ring 406 is disposed between the two sets of support frames 106.

[0061] During the process of controlling the rotation and vibration of the drive shaft 401 by the drive mechanism, the drive shaft 401 drives the impact ring 406 to move through the elastic ring 405, so that the impact ring 406 repeatedly impacts the support frame 106, causing the inner shell 103 to vibrate, improving the arch breaking effect. Moreover, the setting of the elastic ring 405 can effectively adapt to the offset of the drive shaft 401, avoiding rigid impact that could damage the drive shaft 401 and the support frame 106.

[0062] Furthermore, limit rings 407 are provided on both sides of the impact ring 406. The impact ring 406 contacts the limit rings 407, and the limit rings 407 are sleeved on the drive shaft 401 and fixedly connected to it. The setting of the limit rings 407 can prevent the impact ring 406 from detaching from the elastic ring 405, and at the same time prevent the impact ring 406 and the elastic ring 405 from sliding along the axis of the drive shaft 401 and detaching from the two sets of support frames 106, thereby improving the stability of the device.

[0063] like Figure 2 , 3 As shown in Figures 6 and 7, in this embodiment, a second vibration component is also provided on the inner shell 103. The second vibration component is connected to the output shaft of the drive motor 501. When the output shaft of the drive motor 501 rotates, the inner shell 103 is vibrated through the second vibration component. The second vibration assembly includes a drive disc 502 mounted on the output shaft of a drive motor 501, a drive column 503 mounted on the drive disc 502, an mounting rod 203 mounted on the inner shell 103, a limit plate 205 and a limit block 204 mounted on the mounting rod 203, an mounting ring 603 slidably mounted on the mounting rod 203, the mounting ring 603 being located between the limit plate 205 and the limit block 204, an mounting plate 601 mounted on the mounting ring 603, a wedge block 605 and an impact column 602 mounted on the mounting plate 601, during the rotation of the drive disc 502, the mounting ring 603 is driven to slide on the mounting rod 203 by the inclined surface cooperation between the drive column 503 and the wedge block 605, an elastic element 604 is provided between the mounting ring 603 and the limit plate 205, and a groove 202 for the drive disc 502 to rotate is provided on the support frame 201.

[0064] During startup, the drive motor 501 drives the drive disc 502 to rotate. As the drive disc 502 rotates, the engagement of the drive column 503 and the inclined surface of the wedge block 605 causes the mounting ring 603 to slide along the axis of the mounting rod 203, simultaneously compressing the elastic element 604. During its movement, the mounting ring 603 also drives the impact column 602 on the mounting plate 601 to move, creating a certain gap between it and the inner shell 103. Once the drive column 503 disengages from the wedge block 605, the elastic element 604 resets the impact column 602, causing it to impact the inner shell 103, thus vibrating the inner shell 103 and improving the arch-breaking effect. Furthermore, the vibration generated by the impact column 602 impacting the inner shell 103 intersects with the vibration generated by the impact ring 406 impacting the support frame 106, allowing the inner shell 103 to experience vibration in multiple directions, further enhancing the arch-breaking effect.

[0065] Specific usage and beneficial effects of the present invention:

[0066] In operation, the material in the hopper is fed into the inner shell 103. During feeding, the drive motor 501 drives the cross coupling 504 to rotate, which in turn drives the eccentrically mounted first Reuleaux block 402 to rotate within the first frame 304. This controls the rotation of the drive shaft 401, which in turn drives multiple sets of anti-bridging devices 404 to rotate, breaking up the powder and improving the efficiency of powder conveying. Furthermore, as the drive shaft 401 rotates, the vibration generated by the first Reuleaux block 402 moving within the first frame 304 causes the anti-bridging devices 404 to vibrate, further enhancing the anti-bridging effect. Additionally, during its movement, the drive shaft 401 impacts the receiving frame 106 through the cooperation of the elastic ring 405 and the impact ring 406, driving the inner shell 103 to vibrate, thereby further improving the anti-bridging effect. The triple arch-breaking effect is formed by the rotation of the arch breaker 404, the vibration generated by the first Reuleaux triangle 402 and the first square 304, and the vibration generated by the impact ring 406 impacting the receiving frame 106. This effectively prevents the powder from accumulating inside the inner shell 103 and forming an arch during the feeding process, thereby improving the feeding efficiency.

[0067] During operation, the drive motor 501 drives the drive disc 502 to rotate during startup. As the drive disc 502 rotates, the drive column 503, in conjunction with the wedge block 605, causes the mounting ring 603 and mounting plate 601 to slide along the axis of the mounting rod 203, simultaneously compressing the elastic element 604. This causes the impact column 602 to disengage from the inner shell 103. The drive disc 502 continues to rotate until the drive column 503 disengages from the wedge block 605. The elastic element 604 then allows the impact column 602 to strike the inner shell 103, further vibrating it and enhancing the arch-breaking effect. Furthermore, the vibration direction of the second vibration component intersects with that of the first vibration component, resulting in an even better arch-breaking effect.

[0068] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
