Anti-caking and arch-breaking device for sludge storage bin

Abstract

This utility model provides a sludge storage silo anti-caking and arch-breaking device, relating to the field of calcium fluoride production technology. It includes a storage hopper, a connecting frame, and a shell. The bottom of the storage hopper is equipped with an arch-breaking mechanism, and the shell contains a driving mechanism. The output of the rotary motor drives a turntable to rotate at the bottom of the shell. The turntable, through a convex rod, moves a sliding frame in a circular motion. A linkage rod is integrated with the sliding frame, and a guide frame restricts the movement trajectory of the linkage rod, driving it to move linearly back and forth. The linkage rod is integrated with a vibrating block through a connecting rod, which in turn drives the vibrating block to move linearly back and forth. During this process, the vibrating block drives the slider to continuously impact the limiting frame, causing vibration at the bottom of the storage hopper. The vibrating block also agitates the sludge at the bottom of the storage hopper, breaking up any sludge buildup inside and allowing the sludge to discharge smoothly downwards.

Description

Technical Field

[0001] This utility model relates to the field of calcium fluoride technology, and in particular to a device for preventing sludge storage from caking and arching. Background Technology

[0002] Drying and separating calcium fluoride sludge is a key step in resource utilization. The sludge moisture content is reduced to below 50% by using high-efficiency dewatering equipment (such as plate and frame filter press), and then high-temperature drying is carried out using conductive or drum dryers to remove organic matter and residual moisture. During the drying process, the temperature needs to be controlled between 150-300℃ to avoid calcium fluoride decomposition. After the final product is crushed and screened, the purity of calcium fluoride can reach 85%-95%, which can be used as industrial raw material in ceramics, cement and other industries. In real-world working environments, sludge storage silos often face the problem of sludge agglomeration causing obstructed discharge. Sludge has a high water content and is sticky. The temperature and humidity inside the silo vary greatly, and sludge easily adheres to the silo walls, bottom, and around the discharge port. Over time, it agglomerates into lumps, blocking the discharge channel. This agglomeration is even more severe in low-temperature environments, leading to frequent equipment failures, affecting normal production, and increasing cleaning costs and time. Therefore, this utility model proposes a sludge storage silo anti-caking and arch-breaking device to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an anti-caking and anti-arching device for sludge storage silos, which solves the problem in the prior art where large temperature and humidity changes within the storage silo cause sludge to easily adhere to the silo walls, bottom, and around the discharge port, eventually condensing into lumps and blocking the discharge channel.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a sludge storage silo anti-caking and arch-breaking device, comprising a storage hopper, a connecting frame and a shell, wherein a set of connecting frames are symmetrically fixedly connected to both sides of the bottom of the storage hopper, and the shell is fixedly connected to the bottom of the connecting frame; an arch-breaking mechanism is provided at the bottom of the storage hopper, and a driving mechanism is provided inside the shell.

[0005] A further improvement is made in that: the arch-breaking mechanism includes a limiting frame, a vibrating block, a slider, a connecting rod, and a guide block. A set of limiting frames is symmetrically fixedly connected to both sides of the bottom of the storage hopper. A connecting rod is also symmetrically slidably connected to both sides of the bottom of the storage hopper. A vibrating block is fixedly connected to one end of the connecting rod. A slider is symmetrically fixedly connected to both ends of the vibrating block. A guide block is fixedly connected to the top of the limiting frame located in the middle of the storage hopper.

[0006] A further improvement is that the guide block is shaped as a triangle, one end of the slider is inserted into the interior of the limiting frame, and the bottom of the limiting frame has symmetrical slots on both sides.

[0007] A further improvement is that a telescopic sleeve is fitted on the outer side of the connecting rod, and connecting rings are symmetrically provided at both ends of the telescopic sleeve. Connecting bolts are inserted inside the connecting rings, and the two connecting rings are fixedly connected to the vibrating block and the inner wall of the bottom of the storage hopper respectively through the connecting bolts.

[0008] A further improvement is made in that: the driving mechanism includes a turntable, a protruding rod, a sliding frame, a linkage rod, and a guide frame. The turntable is rotatably connected to the bottom of the housing, and the protruding rod is fixedly connected to the outer side of the turntable. The linkage rod is slidably connected to one side of the bottom of the housing through the guide frame. One end of the linkage rod is fixedly connected to the sliding frame, the top end of the protruding rod passes through the interior of the sliding frame, and the other end of the linkage rod is fixedly connected to one end of the connecting rod.

[0009] A further improvement is that a rotary motor is fixedly installed at the bottom of the housing, and the output end of the rotary motor passes through the bottom of the housing and is fixedly connected to the bottom of the turntable.

[0010] A further improvement is that a protective shell is fixedly installed at the bottom of the housing, the protective shell is wrapped around the rotating motor, and multiple rectangular anti-collision strips are evenly distributed on the outer side of the protective shell.

[0011] The beneficial effects of this utility model are as follows: the output end of the rotary motor can drive the turntable to rotate at the bottom of the housing. The turntable moves the sliding frame in a circular motion through the convex rod. The linkage rod is connected to the sliding frame as a whole, and the guide frame restricts the movement trajectory of the linkage rod, so as to drive the linkage rod to move linearly back and forth. The linkage rod is connected to the vibrating block as a whole through the connecting rod. The linkage rod can drive the vibrating block to move linearly back and forth through the connecting rod. During this process, the vibrating block drives the slider to continuously collide with the limiting frame, so that the bottom of the storage hopper vibrates. The vibrating block can also turn over the sludge at the bottom of the storage hopper, so as to break up the sludge inside the storage hopper and make the sludge inside the storage hopper discharge smoothly downwards. This solves the problem in the prior art that the temperature and humidity inside the storage hopper change greatly, and the sludge is easy to adhere to the hopper wall, bottom and discharge port. Over time, it will solidify into lumps and block the discharge channel. Attached Figure Description

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a sludge storage anti-caking and arch-breaking device, including a storage hopper 1, a connecting frame 2, and a shell 3. A set of connecting frames 2 are symmetrically fixedly connected to both sides of the bottom of the storage hopper 1, and the shell 3 is fixedly connected to the bottom of the connecting frame 2. An arch-breaking mechanism is provided at the bottom of the storage hopper 1, and a driving mechanism is provided inside the shell 3. When the sludge inside the storage hopper 1 solidifies and affects the discharge from the bottom of the storage hopper 1, the arch-breaking mechanism can be driven to move linearly back and forth, so that the arch-breaking mechanism collides with the bottom of the storage hopper 1 and generates vibration, and can also play the role of turning over the material, so as to break up the solidification inside the storage hopper 1 and allow the sludge inside the storage hopper 1 to be discharged smoothly downward.

[0016] The driving mechanism includes a turntable 8, a protruding rod 9, a sliding frame 10, a linkage rod 11, and a guide frame 12. The turntable 8 is rotatably connected to the bottom of the housing 3, and the protruding rod 9 is fixedly connected to the outer side of the turntable 8. The linkage rod 11 is slidably connected to one side of the bottom of the housing 3 through the guide frame 12. One end of the linkage rod 11 is fixedly connected to the sliding frame 10, and the top end of the protruding rod 9 passes through the interior of the sliding frame 10. The other end of the linkage rod 11 is fixedly connected to one end of the connecting rod 7. A rotary motor 13 is fixedly installed at the bottom of the housing 3. The output end of the rotary motor 13 passes through the bottom of the housing 3 and is fixedly connected to the bottom of the turntable 8. The output end of the rotary motor 13 can drive the turntable 8 to rotate at the bottom of the housing 3. The turntable 8 moves the sliding frame 10 in a circular motion through the protruding rod 9. The linkage rod 11 is connected to the sliding frame 10 as a whole, and the guide frame 12 restricts the movement trajectory of the linkage rod 11 to drive the linkage rod 11 to move linearly back and forth.

[0017] The arch-breaking mechanism includes a limiting frame 4, a vibrating block 5, a slider 6, a connecting rod 7, and a guide block 14. A set of limiting frames 4 are symmetrically fixedly connected to both sides of the bottom of the storage hopper 1. A connecting rod 7 is also symmetrically slidably connected to both sides of the bottom of the storage hopper 1. A vibrating block 5 is fixedly connected to one end of the connecting rod 7. A slider 6 is symmetrically fixedly connected to both ends of the vibrating block 5. A guide block 14 is fixedly connected to the top of the limiting frame 4 located in the middle of the storage hopper 1. The linkage rod 11 is connected to the vibrating block 5 as a whole through the connecting rod 7. The linkage rod 11 can drive the vibrating block 5 to move linearly back and forth through the connecting rod 7. During this process, the vibrating block 5 drives the slider 6 to continuously collide with the limiting frame 4, causing the bottom of the storage hopper 1 to vibrate. The vibrating block 5 can also turn over the sludge at the bottom of the storage hopper 1 to break up the coagulation inside the storage hopper 1, so that the sludge inside the storage hopper 1 can be discharged smoothly downwards.

[0018] The guide block 14 is triangular in shape. One end of the slider 6 is inserted into the interior of the limiting frame 4. The limiting frame 4 has symmetrical slots on both sides of its bottom. The outer side of the connecting rod 7 is fitted with a telescopic sleeve. The two ends of the telescopic sleeve are symmetrically provided with connecting rings. Connecting bolts are inserted inside the connecting rings. The two connecting rings are fixedly connected to the vibrating block 5 and the inner wall of the bottom of the storage hopper 1 respectively through the connecting bolts. The triangular guide block 14 cooperates with the vibration to guide the sludge to flow downwards and avoids interfering with the flow of the sludge. The telescopic sleeve can wrap around the connecting rod 7 to prevent sludge from falling on the connecting rod 7 and affecting its movement. Each time the sludge is discharged, the interior of the storage hopper 1 will be rinsed clean to prevent sludge residue in the storage hopper 1 from interfering with its normal operation.

[0019] A protective shell is fixedly installed at the bottom of the housing 3. The protective shell covers the rotary motor 13. Multiple rectangular anti-collision strips are evenly distributed on the outer side of the protective shell. The protective shell and anti-collision strips can separate the rotary motor 13 from external objects, preventing external objects from directly contacting the rotary motor 13 and protecting the rotary motor 13.

[0020] The anti-caking and arch-breaking device for the sludge storage silo has a rotary motor 13 whose output can drive a turntable 8 to rotate at the bottom of the housing 3. The turntable 8 moves the sliding frame 10 in a circular motion via a protruding rod 9. The linkage rod 11 is connected to the sliding frame 10 as a whole, and the guide frame 12 restricts the movement trajectory of the linkage rod 11, thereby driving the linkage rod 11 to move linearly back and forth. The linkage rod 11 is connected to the vibrating block 5 as a whole via a connecting rod 7. The linkage rod 11 can drive the vibrating block 5 to move linearly back and forth via the connecting rod 7. During this process, the vibrating block 5 drives the slider 6 to continuously collide with the limiting frame 4, causing the bottom of the storage hopper 1 to vibrate. The vibrating block 5 can also turn over the sludge at the bottom of the storage hopper 1, thereby breaking up the sludge inside the storage hopper 1 and allowing the sludge inside the storage hopper 1 to be discharged smoothly downwards.
