Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, in particular to a conveyor belt dust collection and processing device. Background Art

[0002] Belt conveyor is a kind of continuous transportation equipment with traction, which is widely used in coal, electricity, metallurgy, mining, ports, building materials, chemical industry, light industry, petroleum, transportation and other industries. It can be used to transport bulk, granular and bulk materials. It can transport continuously, efficiently and at a large angle, and has the advantages of easy use, reliable operation, easy maintenance and low cost.

[0003] The length of a single conveyor belt varies from tens of meters to hundreds of meters. Depending on the use environment, it can be transported by a single unit, or multiple units can be combined or combined with other conveying equipment to form a horizontal or inclined mechanical conveying system.

[0004] When the belt conveyor is in operation, dust is often generated, which is very harmful to the on-site working environment and the health of the operators, and can also damage the running equipment. Long-term accumulation of dust poses a safety hazard. Therefore, the belt conveyor often needs to be equipped with dust removal equipment to achieve the effect of reducing dust.

[0005] The reasons for dust generation during conveyor operation are:

[0006] 1. The height difference between conveyors causes dust to fly. That is, when the material falls from the head of one conveyor to the tail of another conveyor, a lot of dust will be generated at the material throwing point. When the material falls from the lower end of the hopper to the next level conveyor belt, a lot of dust will also be generated at the material landing point due to the falling of the material. The existing dust removal device cannot effectively handle it, making the transportation environment relatively bad.

[0007] 2. Dust generated by loose and fine dust and particles adhering to the conveyor belt. The finer dust generates floating dust under the action of the induced wind when the conveyor belt is running;

[0008] 3. Dust accumulated from daily operation in the transportation channel.

[0009] Dust control on belt conveyors has always been one of the problems plaguing the industry. In the existing technology, dust problems are mainly solved by fans and dust covers, which have low dust removal rates, poor effects, high costs, and are not easy to install in narrow transportation environments. There is also a dust removal method that uses water spray, which requires a lot of water, increases the moisture and viscosity of the material, and the water spray nozzle has high requirements for water quality, and the subsequent operation and maintenance costs are high and difficult. The dust removal method of adding an air duct at the drop point of the conveyor transfer station requires the pipeline to transport the airflow containing dust, and long-term use will cause pipeline blockage. The pulse dust collector has high energy consumption because the airflow has to flow through the pipeline and the bag in the dust removal chamber, and it also requires people. Workers need to regularly clean the accumulated powder in the bag, and the bag is used as a dust filtering device. The dust box is a closed space and there are safety hazards. The dust bag is often blocked due to the high viscosity of the dust (water, steam, etc.), and the dust removal effect cannot be achieved. Cleaning is time-consuming and labor-intensive, maintenance is difficult, and the collected dust is not easy to handle. There is also a dust removal equipment that installs a dust cover on the entire conveyor belt. Due to the long length of the conveyor belt, this method is not conducive to equipment operation and maintenance. When a fault occurs at a certain position of the conveyor belt, inspection and maintenance are very inconvenient, and the dust cannot be effectively handled, posing a safety operation hazard. Summary of the invention

[0010] In order to solve the above problems, according to the above-mentioned on-site environmental conditions and the shortcomings and deficiencies of existing dust removal equipment technology, the purpose of the present invention is to provide a conveyor belt dust collection and treatment device, which has a simple structure, reliable performance, easy installation, does not affect the maintenance of the conveyor belt, and can achieve better dust removal and treatment effects for particles of different sizes, and dusts of different humidity and viscosity, with a low failure rate.

[0011] The present invention adopts the following technical scheme: a conveyor belt dust collection and processing device, characterized in that it includes a dust collector, a conveyor belt dust removal device, a throwing point dust suction device, and a material dropping point dust suction device.

[0012] The conveyor belt dust removal device comprises a dust removal hood, a collecting gill, and an air duct fan.

[0013] The dust collecting hood is arranged along the length direction of the conveyor belt. The dust collecting hood is formed by overlapping multiple sections of telescopic hood bodies. The movable end of the hood body is provided with an overlapping portion. Each section of the hood body can be slidably covered above the conveyor belt through a slide rail. The hood body is provided with a telescopic device that enables the hood body to achieve telescopic action. The center of the top of the hood body is provided with an upwardly raised air duct groove along the length direction. The air duct groove and the collecting gills arranged below constitute a collecting air duct along the length direction of the dust collecting hood. A group of supporting frames are arranged at a certain distance on each section of the hood body.

[0014] The collecting gill is fixed on the dust removal cover, and the collecting gill is formed by overlapping a plurality of gill bodies in sequence, and adjacent gill bodies are connected by hinge chains to achieve telescopic extension, and a dust collecting gap is provided at the overlap between adjacent gill bodies;

[0015] The duct fans are fixed inside the collecting duct of the dust collector, and a group of duct fans are arranged at intervals along the length direction of the collecting duct.

[0016] The dust collector comprises a shell, a spiral blade, and a transmission shaft. The dust collector is composed of a first collection section, a first conveying section, a second collection section, and a second conveying section which are sequentially connected from top to bottom. The inner diameter of the collection section is larger than the conveying section. The diameter of the spiral blade is matched with the first collection section, the first conveying section, the second collection section, and the second conveying section from top to bottom. The outer edge of the spiral blade is close to the inner wall of the shell. The transmission shaft is matched with the auger motor.

[0017] The throwing point dust suction device is arranged at the material throwing point at the material transfer place, and the throwing point dust suction device comprises a first dust suction hood and a first dust suction fan. The first dust suction hood is arranged in front of the material throwing direction, and the throwing point dust suction device is connected with the first dust inlet of the first collecting section through a dust suction pipeline.

[0018] The dust suction device at the drop point is arranged at the drop point of the material transfer place. The dust suction device at the drop point includes a second dust suction hood and a second dust suction fan. The second dust suction hood is arranged inside the dust removal hood at the drop point. The dust suction device at the drop point is connected to the second dust inlet of the second collection section through a dust suction pipeline.

[0019] Further: the telescopic device includes a telescopic motor, a driving shaft, a transmission gear, and a transmission chain. The telescopic motor transmits power to the driving shaft through a transmission mechanism. The two ends of the driving shaft are respectively connected to the transmission chains located on the left and right sides of the conveyor belt. The transmission chains on the left and right sides of the conveyor belt are respectively connected to the supporting frame of the dust cover of the overlapping part.

[0020] Further: the overlapping part includes an overlapping bracket and a reset spring. The overlapping bracket can be rotatably hinged on the supporting frame of the movable end of each section of the cover body. The two ends of the reset spring are respectively connected to the overlapping bracket and the supporting frame of the movable end. The overlapping point of the adjacent cover bodies is provided with an overlapping limit switch. When the telescopic device drives the cover body to extend to the overlapping point, the overlapping bracket will touch the overlapping limit switch. Since the overlapping limit switch limits the forward movement of the overlapping bracket, the upper end of the overlapping bracket will tilt forward and overlap the end of the other end of the cover body in front. At the same time, the overlapping limit switch controls the telescopic device to stop working.

[0021] Furthermore: the inclination angle and power of the air duct fan are adjustable.

[0022] Furthermore: the width and height of the first dust hood are both greater than the dust removal hood, and the first dust hood is arranged to be inclined upward facing the direction in which the materials are thrown out.

[0023] Furthermore: a windshield is provided on the inner wall of the shell of the first collecting section and the second collecting section. The windshield is located below the adjacent spiral blades and is tilted downward.

[0024] Furthermore: the gill body of the collecting gill is provided with a gill body groove along the length direction of the collecting gill, and the gill body grooves on two adjacent gill bodies are staggered.

[0025] Further: the collecting air duct is a cylindrical barrel structure along the length direction of the dust collector.

[0026] Furthermore: a dust storage section is provided below the second conveying section, and a butterfly valve is provided at the lower end of the dust storage section.

[0027] The beneficial effects of the present invention are:

[0028] 1. The present invention is suitable for various on-site operating environments of conveyors, and solves the shortcomings and deficiencies of current dust removal equipment. It has a simple structure, reliable performance, and is easy to install. It does not affect the operation and maintenance of the conveyor, and can achieve better dust removal and processing effects for particles of different sizes, as well as dusts of different humidity and viscosity, with a low failure rate.

[0029] 2. The dust hood is made up of multiple sections of retractable hood bodies, and the movable end of the hood is provided with an overlapping part. Each section of the hood can be slidably covered above the conveyor belt through a slide rail. This structural design allows the dust hood to control the contraction and extension of the dust hood when it is working or maintained. And because the dust hood is made up of multiple sections of retractable hood bodies, when a problem occurs in a certain part, only a certain section of the hood needs to be folded up, which is easy to operate, saves time and effort, and is also convenient for maintenance of the dust hood.

[0030] 3. An upwardly raised air duct groove is provided at the center of the top of the hood along the length direction. The air duct groove and the collecting gills arranged below constitute a collecting air duct along the length direction of the dust hood. The collecting air duct can suck the dust on the conveyor belt into the collecting air duct, and form an airflow along the length direction of the collecting air duct in the collecting air duct. The airflow drives the dust to drift forward until the end of the conveyor belt is sucked into the dust collector by the dust suction device.

[0031] 4. The collecting gills are formed by overlapping multiple gill bodies in sequence. Dust collecting gaps are set at the overlaps between adjacent gill bodies. The dust on the conveyor belt will be sucked into the collecting air duct from the collecting gaps. The airflow entering from the collecting gaps flows along the direction of the airflow in the collecting air duct, and the dust in the collecting air duct will not return to the cover through the dust collecting gaps. A group of duct fans are set at intervals along the length of the collecting air duct. The inclination angle and power are adjustable. The inclination angle and power of the fan can be adjusted according to the particle size and humidity of the dust under actual working conditions to achieve the best airflow in the collecting air duct, driving the dust to drift forward until the end of the conveyor belt is sucked into the dust collector by the dust suction device. At the same time, no large airflow will be generated in the dust removal hood, so that the dust on the conveyor belt will be lifted up, avoiding the dust from settling on the collecting gills after entering the collecting air duct, and achieving the best dust removal effect.

[0032] 5. The collecting gills are formed by overlapping multiple gill bodies in sequence, and the adjacent gill bodies are connected by hinge chains to achieve expansion and contraction. This structural design allows the gills to contract when the cover contracts, and the adjacent gill bodies are continuously concentrated and overlapped together as they contract. When the cover is extended and opened, the gills can be extended together with the extension of the cover, and the adjacent gill bodies are continuously opened, overlapping only the edge parts of the gill bodies, so that the operation is smooth and the failure rate is low.

[0033] 6. The gill bodies of the collecting gills are provided with gill body grooves along the length direction of the collecting gills, and the gill body grooves on two adjacent gill bodies are staggered. This structural design can ensure that in addition to the dust collection gap at the overlapping part of the adjacent gill bodies, dust can also enter the collecting air duct through the gill body grooves, and the airflow entering from the gill body grooves merges into the airflow of the collecting air duct to form an overall airflow, which can well drive the dust to drift forward.

[0034] 7. The dust collector comprises a shell, a spiral blade, and a transmission shaft. The outer edge of the spiral blade is close to the inner wall of the shell. This structural design forms a spiral channel from top to bottom between the spiral blade and the cover body. When the dust is sucked into the dust collector through the fan, the airflow drives the dust into the spiral channel. During the advancement of the spiral, the flow rate of the airflow will continue to decrease, and the dust will hit the inner wall of the shell due to centrifugal force, so the dust will continue to settle on the spiral blade. When more dust is collected, the spiral blade can be turned on and off to rotate, and the dust in it is discharged downward. This dust removal method has a good dust removal effect for dust of different types, sizes, humidity and weights, does not require regular maintenance, and avoids the problem that the traditional bag dust removal device has poor dust removal effect for dust of different types, sizes, humidity and weights, and also avoids the problem that the bag is affected by dust adhesion and needs frequent cleaning and maintenance. The rotation of the spiral blade can discharge the collected dust well without clogging and adhesion.

[0035] 8. Wind shields are provided on the inner walls of the shells of the first and second collection sections. The wind shields are located below the adjacent spiral blades and are tilted downward. This structural design can prevent the gap between the spiral blades and the inner wall of the shell from blowing upward, affecting the overall dust removal effect of the spiral channel. The downward tilt can reflect the upward wind back to avoid the turbulence between the gaps affecting the dust settling.

[0036] 9. The width and height of the first dust hood are larger than the dust removal hood, and the first dust hood is tilted upward facing the material throwing direction. This structural design can ensure that the dust generated at the material throwing point and the dust floating from the collection air duct can be effectively sucked into the dust collector, and will not overflow to the outside to affect the overall dust removal effect.

[0037] 10. A dust storage section is also provided below the second conveying section, and a butterfly valve is provided at the lower end of the dust storage section. The dust storage section can temporarily store and gather the dust collected by the dust collector, and the butterfly valve can prevent the dust or airflow in the dust hood below from rushing upward into the dust collector. When the dust in the dust collector accumulates a lot, turn on the switch to rotate the spiral blades to discharge the dust downward. The dust in the dust storage section generates pressure due to the downward pressure of the dust on the upper spiral blades. This pressure helps the dust to gather and form a group. When the pressure reaches the set value of the butterfly valve, the dust in the dust storage section is discharged downward to the conveyor belt below. At the same time, the dust gathering and forming a group can effectively prevent the dust from being dispersed again due to the dust being too fine and small, forming dust.
