Abstract
Description
Technical Field
[0001] This article discloses a multi-adaptive, impact-resistant, wear-resistant, and anti-clogging chute conveying device, belonging to the field of material conveying machinery. Specifically, it is a device that can adjust the appropriate working conditions according to the material feed rate and material properties to improve material conveying efficiency and reduce unplanned downtime caused by material blockage. It has the advantages of high transmission efficiency, impact resistance, wear resistance, and self-cleaning. Background Technology
[0002] Currently, materials such as coal and ore are typically transported via chutes or feeders. However, due to years of continuous mining, the grade of coal and ore has decreased. Both raw ore mined underground and washed products contain a large amount of moisture, causing the materials to become sticky, clumpy, and have poor flowability, easily clogging chutes or feeding devices and severely impacting production. Current solutions often involve installing vibrating motors on the outside of the chutes, but the effect is not significant. When chutes are clogged, manual unclogging is necessary, which is time-consuming and labor-intensive. Furthermore, the turning points of ordinary chutes are prone to wear and damage to the receiving devices due to the impact of the material, increasing maintenance requirements.
[0003] The purpose of this invention is to solve the problem of sticky and wet materials clogging chutes or feeding conveyors, so that the conveying system can operate continuously, ensure production throughput, and extend the service life of the equipment. Summary of the Invention
[0004] This invention relates to a multi-adaptive, wear-resistant, and anti-clogging chute conveying device. The purpose of this invention is to provide a vibrating device that enables continuous material conveying. This device can adapt to the conveying of materials with varying degrees of viscosity and wetness, exhibiting strong adaptability. This invention features multiple elastic spiral blades arranged above a high-frequency vibrating bed surface, which increases the material conveying capacity and reduces wear caused by material conveying. The elastic spiral conveying device has internal flow channels with unidirectional lubricating water flowing out from the lubrication friction surface, providing cleaning capabilities and significantly improving transmission efficiency. Small amounts of material on the vibrating bed surface can be conveyed through high-frequency vibration. This invention can completely solve the problem of clogging chutes or feeders by viscous and wet materials, and has the advantages of simple structure and high transmission efficiency.
[0005] This invention is achieved using the following technical solution: a multi-adaptive, abrasion-resistant, and anti-clogging chute conveying device, comprising a vibration system, a spiral system, a lubrication system, and a support. The vibration system includes a vibrating motor, a vibrating bed, vibration-damping spring supports, side plates, a back plate, and a cover plate. The spiral system includes elastic spiral blades, an intermediate shaft, a motor, a reducer, a coupling, a head bearing, a small tail bearing, a large tail bearing, a bearing sleeve, a bearing seat, and a bearing cover. The lubrication system includes an inclined A-beam, an internal water pipe, and a water pipe. The vibrating bed, side plates, back plate, and cover plate are combined to form a chute with openings at both ends. The chute is connected to the raw material silo outlet at the top and to a conveyor belt, screening device, or washing device at the bottom to achieve uniform feeding. A vibrating motor is installed outside the chute to achieve high-frequency vibration. Inside the chute, the spiral system is installed parallel to the vibrating bed surface. The head of the spiral system is supported by a support, and the tail is supported by an inclined A-beam. The water in the lubrication system enters the interior of the elastic spiral blade with flow channel through the water pipe. When the elastic spiral blade rotates, the water inside the flow channel flows out from the small hole of the elastic spiral blade due to centrifugal force.
[0006] The installation method of this invention is as follows: A multi-adaptive, wear-resistant, and anti-clogging chute conveyor device is connected to the raw material silo outlet at the top and to a transfer belt, screening device, or washing device at the bottom. The vibration system is mounted on a support via a vibration isolation spring device. The spiral system is installed parallel to the vibrating bed inside the device and fixed by a support and an inclined A-beam. The elastic spiral blades are welded from two spiral plates, forming a flow channel inside, and are covered with elastic polyurethane material on the outside. Small holes are opened on the blades in contact with the material to facilitate water flow. The head of the intermediate shaft has holes along the spiral trajectory of the elastic spiral blades, and lubricating water enters the head of the intermediate shaft through water pipes and water pipes inside the shaft. When the spiral system is working, the lubricating water in the head of the intermediate shaft is subjected to centrifugal force and enters the internal flow channel of the elastic spiral blades through the holes in the head of the intermediate shaft, and further flows out from the small holes on the elastic spiral blades. The elastic spiral blades are fixed on the intermediate shaft, and the motor, reducer, coupling, and head bearing are connected in series and fixed to the intermediate shaft. The water pipe passes through the triangular area of the inclined A-beam and the bearing seat and is connected to the water pipe inside the shaft.
[0007] The working principle of this invention is as follows: Material enters a multi-adaptive, wear-resistant, and anti-clogging chute conveying device from the raw material silo outlet. The material is first filled in the gaps between multiple elastic spiral blades, which propel the material forward rapidly to achieve the conveying purpose. A water pipe runs through the central shaft of the spiral system, and the head of the central shaft has an opening. Due to centrifugal force, water flows through the opening in the central shaft into the interior of the elastic spiral blades. Simultaneously, small holes in the elastic spiral blades allow a small amount of water to flow out and adhere to them. This small amount of water between the elastic spiral blades and the material reduces friction and follow-along movement, thus extending the service life of the elastic spiral blades. A small amount of material that cannot be conveyed below the spiral system is transported via high-frequency vibration.
[0008] The technical advantages of this invention are as follows: A multi-adaptive, wear-resistant, and anti-clogging chute conveying device can adapt to the conveying of bulk materials with different properties, such as dry and viscous materials; the internal elastic spiral blades of the device can buffer the impact of materials and reduce the equipment damage rate; the lubrication system of the device can reduce the wear between materials and elastic spiral blades and extend the service life of the equipment; the device can completely solve the clogging problem of viscous materials in the conveying system, enabling continuous production and greatly reducing the number of unplanned downtimes.

Detailed Implementation
[0021] The invention will be further described below with reference to the accompanying drawings.
[0022] like Figure 1 As shown, a multi-adaptive, abrasion-resistant, and anti-clogging chute conveying device includes a vibration system, a spiral system, a lubrication system, and a support frame. The vibration system includes a vibrating motor 1, a vibrating bed 2, vibration-damping spring supports 3, side plates 4, a back plate 5, and a cover plate 6. The spiral system includes elastic spiral blades 7, an intermediate shaft 8, a motor 9, a reducer 10, a coupling 11, a head bearing 12, a small tail bearing 13, a large tail bearing 14, a bearing sleeve 15, a bearing seat 16, and a bearing cover 17. The lubrication system includes an inclined A-beam 18, an internal water pipe 19, and a water pipe 20. This multi-adaptive, abrasion-resistant, and anti-clogging chute conveying device is connected to the raw material silo outlet at the top and to a transfer belt, screening device, or washing device at the bottom.
[0023] Figure 2 This is a partial perspective view of a multi-adaptive, wear-resistant, and anti-clogging chute conveying device. A vibratory motor drives the vibratory system, which is fixed to a support frame via vibration-damping spring supports. The head of the screw system is fixed to the support frame, and the tail is fixed to the inclined A-beam.
[0024] Figure 3 This is a three-dimensional view of the screw system in a multi-adaptive, abrasion-resistant, and anti-clogging chute conveying device. Figure 4 The diagram shows a cross-sectional view. The elastic helical blade 7 is formed by welding two helical plates, creating an internal flow channel. It is covered with elastic polyurethane material, and small holes are made on the blades in contact with the material to facilitate water flow. The head of the intermediate shaft 8 has holes along the helical trajectory of the elastic helical blade 7. Lubricating water enters the head of the intermediate shaft 8 through water pipe 20 and internal water pipe 19. When the helical system is working, the lubricating water in the head of the intermediate shaft 8 is subjected to centrifugal force and flows through the holes in the head of the intermediate shaft 8 into the internal flow channel of the elastic helical blade 7, and further flows out through the small holes on the elastic helical blade 7. The elastic helical blade 7 is fixed to the intermediate shaft 8, and the motor 9, reducer 10, coupling 11, and head bearing 12 are connected in series and fixed to the intermediate shaft 8.
[0025] Figure 5 This is a schematic diagram of the tail structure of the spiral system. The water pipe 19 inside the shaft is fitted with a small tail bearing 13, which is then fitted with a bearing sleeve 15. The bearing sleeve 15 is fixed to the intermediate shaft 8, and a large tail bearing 14 is fitted inside. Finally, the system is fixed to the inclined beam 18 via a bearing seat 16.
[0026] Figure 6 and Figure 7This is a schematic diagram of the spiral system installation. The head of the spiral system is mounted on the bracket 21 via motor 9, and the tail is mounted on the inclined beam 18 via bearing seat 16, maintaining a certain distance from the vibrating bed surface. This distance needs to be greater than the amplitude of the vibrating bed 2 to prevent the elastic spiral blades 7 from colliding with the vibrating bed 2 and causing equipment damage. The number of spiral systems can be selected appropriately according to the size of the raw material silo outlet, such as... Figure 7 As shown, if two spiral systems are installed, the distance between the tails of the two spiral systems should be less than the distance between the heads. This can ensure that the feeding is centered and avoid uneven force on the receiving device below, which could lead to accidents.
[0027] Figure 8 and Figure 9 This is a schematic diagram of the water pipe 21 arrangement. Lubricating water enters the internal water pipe 19 through the water pipe 21. To prevent the water pipe 21 from being damaged by material impact, the water pipe is inserted into the inclined A beam 18 and the bearing housing 16. The inclined A beam 18 not only supports the spiral system but also protects the water pipe 21 in the lubrication system.
[0028] Figure 10 The support 21 in a multi-adaptive, wear-resistant, and anti-clogging chute conveying device is constructed of H-steel, and the inclined A-beam 18 is fixed on the support 21.
[0029] The specific working principle of the multi-adaptive, abrasion-resistant, and anti-clogging chute conveying device of the present invention is as follows:
[0030] A multi-adaptive, abrasion-resistant, and anti-clogging chute conveying device is connected to the discharge port of a raw material silo at the top and to a transfer belt, screening device, or washing device at the bottom. Material enters the device from the raw material silo discharge port, initially filling the gaps between multiple elastic spiral blades 7. The elastic spiral blades 7 propel the material forward rapidly, achieving the conveying purpose. An internal water pipe 19 runs through the intermediate shaft 8 of the spiral system, and the head of the intermediate shaft 8 has an opening. When the spiral system operates, the lubricating water in the head of the intermediate shaft 8, under centrifugal force, enters the internal flow channel of the elastic spiral blades 7 through the opening, and further flows out through small holes on the elastic spiral blades 7. The small amount of water medium between the elastic spiral blades 7 and the material reduces friction and following motion, improving the service life of the elastic spiral blades 7. A small amount of material that cannot be conveyed below the spiral system is conveyed by high-frequency vibration. When conveying materials with good flowability, the material can naturally slide down with an angle of repose greater than its own. When conveying materials with moderate flowability, the material can be transported via the vibration system. In this case, the screw system only serves to reduce the impact on the bed surface, and the lubrication system does not operate. When the material conveyed by the vibration system cannot meet the conveying requirements, or when sticky or wet materials may clog the chute, the screw system and lubrication system will start working. After material conveying is completed, the equipment can perform self-cleaning.
[0031] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above description is merely to aid in understanding the method and core ideas of the present invention; furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
