Description

Technical Field

[0001] This utility model belongs to the field of anti-arching technology for raw material batching silos, and in particular, it is a device for preventing arching in raw material batching silos. Background Technology

[0002] Granular raw materials stored in silos are prone to arching due to their own weight and humidity, which can obstruct the flow of raw materials and affect production and storage.

[0003] Existing anti-bridging devices for raw material batching silos typically use vibration or agitation to prevent bridging. This method has a small anti-bridging area, and the agitation cannot reach the inner wall and the discharge port of the silo, making it difficult to clean the raw materials adhering to the silo wall and bottom, thus reducing the efficiency of use.

[0004] A search revealed a Chinese patent document (authorization announcement number CN209423459U) describing a feed anti-bridging device. This device uses the rotation of the hopper cover to allow the stirring blades to agitate the feed in all locations within the hopper, thereby removing feed adhering to the inner wall and preventing spoilage if left untreated for extended periods. A second reduction gearbox slows the rotation speed of the stirring rod while increasing its power, allowing the stirring blades to exert greater force to break up severely bridging feed. However, this device suffers from the problem of failing to clean raw materials bridging the inner wall and bottom of the hopper, thus reducing its efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a device for preventing arching in raw material batching silos, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material batching silo anti-arching device, comprising: a platform and a silo for batching cement raw materials, set at the top of the platform; a chute is provided on the outer periphery of the silo, and two sliders are tightly attached to the inner wall of the chute; a positioning block is fixed on the side of the two sliders that are close to each other; a connecting frame is fixed to the top of the two positioning blocks and attached to the top of the silo; a motor is installed on the vertical side of the connecting frame; a bidirectional screw with its end inserted into the connecting frame is installed on the drive end of the motor; two moving plates are sleeved on the outer periphery of the bidirectional screw; a telescopic rod is installed at the bottom end of each of the two moving plates; and a scraper is installed on the moving part of each of the two telescopic rods.

[0007] The hopper is fixed to the vertical inner wall, and the inner circumference of the hopper is provided with a threaded groove. The inner circumference of the hopper is threaded with a threaded ring, and the inner circumference of the threaded ring is sleeved with a connecting cylinder. The bottom end of the connecting cylinder is fixed with two vertical plates.

[0008] The bottom ends of the two vertical plates are fixed with bottom rings with threaded grooves on their outer circumferences. The top end of the connecting cylinder is equipped with a second rotary motor. The drive end of the second rotary motor is equipped with a second rotating rod that completely penetrates the connecting cylinder. Multiple stirring plates are sleeved on the outer circumference of the second rotating rod.

[0009] The outer circumference of the connecting cylinder is fitted with a collar, and the inner circumference of the collar is threaded with a cover.

[0010] A support frame is connected to the top of the platform, and a first rotary motor is installed at the top of the support frame.

[0011] The first rotating motor has a first rotating rod installed at its drive end, and the first rotating rod completely penetrates the fixed block.

[0012] A box is fixed to the bottom of the platform, and a baffle is fixed to the bottom of the box.

[0013] Two fixed seats are connected to each side of the platform, and two support rods are installed at the bottom of each of the four fixed seats.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] During use, the anti-arching device for the raw material batching silo benefits from the motor located on the vertical side of the connecting frame, which drives two moving plates on the outer periphery of the bidirectional screw to move in opposite directions. During the movement of the moving plates on both sides, the telescopic rods located at the bottom of the moving plates extend and retract, driving the scraper to move, which facilitates the mixing of the raw materials.

[0016] Subsequently, the telescopic rod extends and retracts, driving the scraper to be positioned on both sides of the collar. A first rotary motor, located at the top of the support frame, drives the fixed block to rotate, causing the scraper to rotate and disengage the threaded ring from the hopper. Under the action of the telescopic rod, the scraper rises, and after reaching a certain height, the bottom ring is threadedly connected to the hopper for fixation. A second rotary motor then drives the scraper to break up the raw material at the bottom of the hopper. Simultaneously, the scraper, under the action of the telescopic rod and the first rotary motor, adheres to the inner wall of the hopper. This differs from existing devices that cannot effectively break up clumps adhering to the inner wall and bottom of the hopper, making it easier to break up clumps adhering to the inner wall and the hopper discharge port. This raw material batching hopper anti-clumping device facilitates the mixing of raw materials, unlike existing devices that cannot effectively break up clumps adhering to the inner wall and bottom of the hopper, making it easier to break up clumps adhering to the inner wall and the hopper discharge port.

[0029] Example

[0030] Please see Figures 1 to 6 The main structure of the device consists of a platform 1 and a silo 6 for cement raw material batching, located at the top of the platform 1. The silo 6 is fixed to the platform 1 by welding. A vertical groove 25 is formed on the outer periphery of the silo 6. Two sliders 26 slide against the inner wall of the groove 25. Positioning blocks 27 are fixed to the sides of the two sliders 26 that are close to each other by an integral molding process. The tops of the two positioning blocks 27 are fixed to a connecting frame 24 attached to the top of the silo 6 by bolts. A motor 23 is fixed to the vertical side of the connecting frame 24 by motor base bolts. The drive end of the motor 23 is fixed to a bidirectional lead screw whose end extends into the interior of the connecting frame 24 by a key. The two ends of the bidirectional lead screw are connected to the interior of the connecting frame 24 by bearings. The wall is rotatably connected, and two movable plates 19 are threadedly connected to its outer periphery. The bottom ends of the two movable plates 19 are fixed with telescopic rods 20 by bolts. The bottom ends of the movable parts of the two telescopic rods 20 are fixed with scrapers 21 by bolts. The scrapers 21 slide against the inner wall of the hopper 6. The top of the platform 1 is fixed with a support frame 2 by bolts. The top of the support frame 2 is fixed with a first rotary motor 4 by a flange. The drive end of the first rotary motor 4 is fixed with a first rotating rod by a coupling. The end of the first rotating rod away from the first rotary motor 4 passes through a fixed block 22 and is rotatably connected to the fixed block 22 by a bearing. The hopper 6 is equipped with a switch valve, which is selected according to actual needs.

[0031] The vertical inner wall of the silo 6 is fixed with a partition 7 by welding. The partition 7 has an internal threaded groove on its inner circumference. A threaded ring 14 is threadedly connected inside the partition 7. A connecting cylinder 13 is fitted to the inner circumference of the threaded ring 14 by interference fit. Two symmetrically distributed vertical plates 15 are fixed to the bottom end of the connecting cylinder 13 by welding. The bottom end of the two vertical plates 15 is fixed with a bottom ring 16 with an external threaded groove on its outer circumference by welding. A second rotary motor 17 is fixedly installed at the top end of the connecting cylinder 13 by bolts. The drive end of the second rotary motor 17 is fixedly connected to a second rotating rod that completely penetrates the connecting cylinder 13 by a coupling. The contact part between the second rotating rod and the connecting cylinder 13 is rotatably connected by a bearing. Multiple stirring plates 18 arranged in a ring array are fixedly fitted to its outer circumference by welding.

[0032] A collar 12 is fitted to the outer periphery of the connecting cylinder 13 near the top via an interference fit. The collar 12 has an internal thread on its inner periphery, which connects to a cover 3 for sealing the top of the hopper 6. A box 8 is welded to the bottom of the platform 1, and a cover plate 9 is bolted to the bottom of the box 8. Two symmetrically distributed fixed seats 10 are welded to both sides of the platform 1. Two support rods 11 are bolted to the bottom of each of the four fixed seats 10. Anti-slip pads are fixed to the bottom of the support rods 11 via foot bolts. A magnetostrictive displacement sensor (such as MTS R series, accuracy ±0.05mm) is installed on the piston rod of the telescopic rod 20 to provide real-time feedback on the position of the two cylinders. The PLC compares the position difference and dynamically adjusts the flow rate on one side via an electro-hydraulic proportional valve (such as 4WREE6 type) to ensure that the position synchronization error is ≤0.1mm.

[0033] The first rotary motor 4, the second rotary motor 17, the telescopic rod 20, and the motor 23 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] Working principle

[0035] In use, the raw material batching silo anti-bridging device is used to pour the raw material into the silo 6. The motor 23 set on the vertical side of the connecting frame 24 drives the two moving plates 19 on the outer periphery of the bidirectional screw to move towards each other. During the movement of the moving plates 19 towards each other, the telescopic rod 20 set at the bottom of the moving plate 19 extends and retracts, and the scraper 21 is used to stir the raw material.

[0036] When it is necessary to remove the arches from the material, the scraper 21 is attached to the lower end of the collar 12, and the first rotary motor 4, which is set at the top of the support frame 2, is driven to make the connecting cylinder 13 rotate with the first rotary motor 4. It moves upward with the telescopic rod 20, so that the threaded ring 14 is disengaged from the hopper 7, and the bottom ring 16 is inserted into the hopper 7 for fixation, so that the material can fall. Then the second rotary motor 17 is driven to break up the arches in the material at the lower end of the hopper 6. At the same time, the scraper 21 at the drive end of the telescopic rod 20 and the first rotary motor 4 breaks up the arches attached to the inner wall of the hopper 6.
