Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and in particular to an environmentally friendly dust removal equipment for barite powder processing and crushing. Background Art

[0002] Barite is the most common mineral of barium. Its component is barium sulfate. It is produced in low-temperature hydrothermal veins, such as quartz barite veins, fluorite barite veins, etc. It often coexists with galena, sphalerite, chalcopyrite, cinnabar, etc.

[0003] The production process of barium sulfate is usually divided into two production processes: physical method and chemical method. However, no matter which process is used, the selected barite blocks need to be crushed during the production process. Jaw crusher, as a commonly used crushing machine for barite blocks, is widely used in the barite crushing production industry.

[0004] When the crusher in the prior art crushes barite, a large amount of dust will be generated due to the collision between the stones. The dust gathers inside the crushing device. As the dust increases, some of the dust floats upward and is easily dispersed from the feed port area of ​​the crushing device. Since barite contains heavy metal salts, although they are non-toxic, they can cause symptoms such as chest pain or coughing after inhalation by the human body, and can also have a certain irritating effect on the eyes.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 5The present invention provides a technical solution: an environmentally friendly dust removal device for barite powder processing and crushing, comprising a crushing frame 1, the top of the crushing frame 1 is fixedly connected with a fixed frame 2, the bottom of the crushing frame 1 is fixedly plugged with a conveying frame 3, the bottom of the crushing frame 1 is provided with a screw dragon part 4, the middle part of the crushing frame 1 is provided with a crushing part 14, and the left side of the crushing frame 1 is provided with a mist screen assembly 6, and the mist screen assembly 6 includes a liquid tank 61 fixedly connected to the left side of the crushing frame 1, a concentration cover 62 is provided above the liquid tank 61, and an air supply duct 63 is fixedly plugged on the left side of the concentration cover 62, and a nozzle 64 is fixedly connected to the right side of the concentration cover 62, and the right side of the nozzle 64 is fixedly plugged with the crushing frame 1, and the bottom of the nozzle 64 is fixedly plugged with the crushing frame 1. A water suction pipe 65 is fixedly connected, and the bottom of the water suction pipe 65 is inserted into the interior of the liquid tank 61. There are multiple nozzles 64 and water suction pipes 65. An air supply component 7 is arranged inside and above the air supply duct 63. The air supply component 7 includes a mounting bracket 71 fixedly connected to the top of the air supply duct 63. A first motor 72 is fixedly connected to the inner top of the mounting bracket 71. The output shaft of the first motor 72 is fixedly connected to a long rod 74. The long rod 74 penetrates into the interior of the air supply duct 63 and is fixedly connected to a fan blade 73. The auger part 4 includes a second motor 41 fixedly connected to the right side of the conveying frame 3. The output shaft of the second motor 41 extends into the interior of the conveying frame 3 and is fixedly connected to the auger shaft 42. When in use, the device is fixed between the outside.

[0035] By adopting the above technical solution, the crushing part 14 is a mature existing technology, which is composed of two crushing rollers, and one of the crushing rollers is driven by a motor. Gears are installed on the rotating shafts of the two crushing rollers, and the two gears are meshed to realize the rotation of the crushing rollers to crush the barite powder.

[0036] When the device is in use, the barite to be crushed is transported to the top position of the fixed frame 2 through an external conveying device, and then the barite falls into the interior of the crushing frame 1. It should be noted that the inner wall of the crushing frame 1 is located above the crushing part 14 and is fixedly connected with an inclined guide plate, which is used to guide the barite to the middle position of the two crushing rollers for easy crushing. The crushed barite powder falls under the action of gravity and then enters the interior of the conveying frame 3. At this time, the output shaft of the second motor 41 rotates to facilitate the rotation of the auger shaft 42, thereby transporting the barite powder from right to left, and then discharged from the right opening of the conveying frame 3 and collected.

[0037] When the barite is crushed, a lot of dust will be generated, causing the dust to gather inside the crushing frame 1. As the dust increases, some of the dust may float upward and easily float out from the feed port area of ​​the crushing device, causing the processing workshop environment to be polluted by dust and affecting the health of the workers. For this reason, the present application provides a fog screen assembly 6 and an air supply assembly 7.

[0038] When the device is running, the output shaft of the first motor 72 rotates, and the designed long rod 74 rotates. It should be noted that a shaft seal is provided between the long rod 74 and the air supply duct 63 to ensure the sealing performance of the connection between the long rod 74 and the air supply duct 63. As the long rod 74 rotates, the fan blades 73 can be rotated, so that flowing wind is generated inside the air supply duct 63, and the wind blows in the direction of the concentrated cover 62, and the wind entering the concentrated cover 62 blows inside the wind direction nozzle 64. Since the diameter of the nozzle 64 is small, the air entering the nozzle 64 The wind speed is very fast, and the pressure in the area with fast air speed is relatively small, so that the pressure inside the nozzle 64 is relatively small, which makes it easy for the liquid inside the liquid box 61 to enter the inside of the nozzle 64 through the suction pipe 65, and under the action of the high-speed flowing air, it is easy to blow away the liquid entering the nozzle 64 to form droplets, and because there are multiple nozzles 64 and suction pipes 65, it is easy to form a droplet barrier inside the crushing frame 1 to prevent dust from rising, thereby preventing dust from drifting out from the feed port area of ​​the crushing device, and thus preventing the processing workshop environment from being polluted by dust and affecting the health of workers.

[0039] It should be noted that the sprayed droplets can also play a role in dust reduction when they fall, and the falling barite blocks have greater gravity and can pass smoothly through the droplet barrier.

[0040] Specifically, Figures 2 to 5 As shown, one end of the air supply duct 63 away from the collecting hood 62 is fixedly plugged into the top left side of the conveying rack 3, and the interior of the air supply duct 63 is fixedly connected to a filter rack 10, and the filter rack 10 is in the shape of an inverted funnel. The ring side of the filter rack 10 is fixedly connected to a collecting hood 11, and a scraper 12 is arranged above the filter rack 10, and a plurality of scrapers 12 are arranged, and the side of the plurality of scrapers 12 close to each other is fixedly connected to a long rod 74.

[0041] By adopting the above technical solution, since the dust gathers inside the crushing frame 1 and the dust increases, some of the dust floats downward. Under the action of the rotation of the fan blades 73, the air flow inside the air supply duct 63 is facilitated. When the dust flowing downward reaches the left bottom of the air supply duct 63, it enters the interior of the air supply duct 63 under the action of the air flow, and then reaches the area of ​​the filter frame 10, and is filtered by the filter frame 10. In this way, the dust can be further removed, thereby preventing more dust from overflowing from the left side of the conveying frame 3 and affecting the external environment.

[0042] It should be noted that the filter frame 10 is provided with a plurality of filter holes, which can ensure that air passes through and retain dust, and prevent dust from entering the small-aperture nozzle 64 and causing the nozzle 64 to be blocked, thereby affecting the integrity of the droplet barrier, thereby improving the dust removal effect.

[0043] As the output shaft of the first motor 72 rotates with the long rod 74, the scraper 12 is rotated to scrape the surface of the filter frame 10 to prevent dust from clogging the filter holes and affecting the normal operation of the device, and the scraped dust and impurities are collected inside the collection cover 11.

[0044] Specifically, Figures 2 to 4 As shown, a spray assembly 8 is arranged above the collecting hood 11, and the spray assembly 8 includes a first cam 81 fixedly connected to the top of the outer wall of the long rod 74, and the spray assembly 8 also includes a corrugated bag 82 fixedly connected to the inner rear end of the mounting frame 71, and the front end of the corrugated bag 82 is fixedly connected to a movable plate 83, and the top of the movable plate 83 is slidably connected to the mounting frame 71, and an outlet pipe 84 is fixedly inserted at the left side of the bottom rear end of the corrugated bag 82, and the end of the outlet pipe 84 away from the corrugated bag 82 extends into the interior of the air supply duct 63 and is fixedly connected to a nozzle 85, and an inlet pipe 86 is fixedly inserted at the right side of the bottom rear end of the corrugated bag 82, and the bottom of the inlet pipe 86 is inserted into the interior of the liquid tank 61, and check valves 87 are installed inside the outlet pipe 84 and the inlet pipe 86.

[0045] By adopting the above technical solution, the design of the check valve 87 inside the inlet pipe 86 only allows liquid to flow from bottom to top, and the design of the check valve 87 inside the outlet pipe 84 only allows liquid to flow from the bellows 82 to the direction of the nozzle 85, and the nozzle 85 is provided with multiple spray holes. The bellows 82 itself is elastic and can ensure the reset of the movable plate 83.

[0046] As the output shaft of the first motor 72 rotates with the long rod 74, the first cam 81 can be rotated. When the protruding end of the first cam 81 approaches and squeezes the movable plate 83, the top of the movable plate 83 moves toward the rear end along the mounting frame 71 to squeeze the bellows 82, thereby compressing the bellows 82, making it easier for the liquid inside the bellows 82 to enter the outlet pipe 84, then enter the nozzle 85 and be sprayed out from the nozzle 85, and then spray to the area of ​​the air supply duct 63 above the filter frame 10, so as to moisten the dust entering there, avoid dust scattering when the scraper 12 scrapes, thereby further facilitating the dust to enter the collection cover 11 for collection.

[0047] When the protruding end of the first cam 81 is away from the movable plate 83, the movable plate 83 moves toward the front end under the action of the bellows 82's own elastic force, and the bellows 82 stretches, making it easier for the liquid inside the liquid tank 61 to enter the bellows 82 through the inlet pipe 86, preparing for the next liquid spraying.

[0048] An adding pipe is inserted on the top left side of the liquid box 61 for adding liquid, and the added liquid can be water.

[0049] Specifically, Figure 2 , Figure 3 and Figures 5 to 8 As shown, the front and rear ends of the interior of the collecting cover 11 are fixedly connected with a guide ring block 13, and the bottom of the filter frame 10 is provided with an output component 9, and the output component 9 includes a second cam 91 fixedly connected to the outer wall of the long rod 74 and located below the fan blade 73, and the output component 9 also includes a debris discharge pipe 92 fixedly plugged on both sides of the collecting cover 11, and the output component 9 also includes two moving rods 93 slidably connected to both sides of the collecting cover 11, and the outer walls of the two moving rods 93 are fixedly connected with piston plates 94, and two piston plates 94 are fixedly connected to a single moving rod 93, and an arc plate 95 is fixedly connected to the side where the two moving rods 93 are close to each other, and a spring 96 is fixedly connected between the arc plate 95 and the inner side of the collecting cover 11, and grooves 97 are provided at positions corresponding to the debris discharge pipe 92 on both sides of the collecting cover 11.

[0050] By adopting the above technical solution, it should be noted that the tops of the two guide ring blocks 13 are designed to be inclined, and the dust and impurities falling on the tops of the guide ring blocks 13 can fall along the inclination on both sides of the collecting cover 11 near the groove 97, which is convenient for concentrating the wetted dust and impurities.

[0051] As the output shaft of the first motor 72 rotates with the long rod 74, the second cam 91 rotates. When the protruding end of the second cam 91 rotates to approach and squeeze the arc plate 95, the arc plate 95 moves with the moving rod 93 in the direction close to the exhaust pipe 92, so that the two piston plates 94 move, and the spring 96 is in a compressed state. It should be noted that in the initial state, the piston plate 94 away from the second cam 91 is inside the exhaust pipe 92, and the piston plate 94 close to the second cam 91 is located at the inner wall of the collection cover 11. When the two piston plates 94 move, the dust and impurities between the two piston plates 94 can be pushed into the interior of the exhaust pipe 92. As the moving rod 93 continues to move in the direction close to the exhaust pipe 92, when the piston plate 94 away from the second cam 91 passes through the interior of the exhaust pipe 92, and the piston plate 94 close to the second cam 91 is located in the exhaust pipe 92 away from the second cam 91, the wet dust can be discharged to avoid excessive dust accumulation affecting the normal operation of the device.

[0052] When the protruding end of the second cam 91 rotates away from the arc plate 95, under the elastic force of the spring 96, the arc plate 95 moves and resets with the moving rod 93 away from the impurity discharge pipe 92, so as to facilitate the next time to push out the dust material.

[0053] It should be noted that the distance between the two piston plates 94 is smaller than the length of the impurity discharge pipe 92, so as to ensure that there is always one piston plate 94 inside the impurity discharge pipe 92 to ensure the sealing effect.

[0054] It should be noted that the annular side of the piston plate 94 fits against the inner wall of the exhaust pipe 92, and in the initial state, the piston plate 94 close to the second cam 91 fits against the inner wall of the groove 97, and chamfers are provided on both sides of the inner walls of the exhaust pipe 92 to facilitate the piston plate 94 to move into the interior of the exhaust pipe 92.

[0055] A through pipe is inserted between the bottom of the centralizing cover 62 and the liquid tank 61. A valve is installed inside the through pipe. Some liquid may enter the centralizing cover 62. The valve is opened at a fixed time to facilitate the return of the liquid to the liquid tank 61.

[0056] Specifically, Figures 2 to 6 and Fig. 9 As shown, a knocking assembly 5 is provided inside the air supply duct 63, and the knocking assembly 5 includes a fixed block 51 fixedly connected to the inner wall of the collection cover 11, and the knocking assembly 5 also includes a sleeve rod 52 fixedly connected to the outer wall of the long rod 74 and located at the bottom of the second cam 91, and a through rod 53 is slidably connected inside the sleeve rod 52, and a ball 54 is rotatably connected to the side of the through rod 53 away from the sleeve rod 52, and the output shaft of the first motor 72 rotates clockwise, and the fixed block 51 is tilted on one side in the counterclockwise direction.

[0057] By adopting the above technical solution, one side of the fixed block 51 in the clockwise direction does not tilt. As the output shaft of the first motor 72 rotates with the long rod 74, the sleeve rod 52, the through rod 53 and the ball 54 rotate. Under the centrifugal force of the rotation, the part of the ball 54 away from the through rod 53 fits with the inner side of the collection cover 11. As the rotation proceeds, when the ball 54 rotates to the inclined position of the fixed block 51, when the ball 54 rotates to the inclined position of the fixed block 51, the through rod 53 slides slightly toward the sleeve rod 52. As the sleeve rod 52, the through rod 53 and the ball 54 continue to rotate, at the moment when the ball 54 is away from the fixed block 51, under the action of centrifugal force, the through rod 53 quickly moves in the direction away from the sleeve rod 52, thereby knocking on the inner wall of the collection cover 11, thereby playing a vibrating role, which facilitates the dust to be smoothly concentrated along the inclined groove 97.

[0058] Working principle: The external conveying device conveys the barite to be crushed to the top position of the fixed frame 2, and then the barite falls into the inside of the crushing frame 1, and the barite falls into the middle position of the two crushing rollers for crushing. The output shaft of the second motor 41 rotates to facilitate the rotation of the auger shaft 42, so that the barite powder is conveyed from right to left, and then discharged from the right opening of the conveying frame 3 and collected.

[0059] The output shaft of the first motor 72 rotates, and the designed long rod 74 rotates, so that the fan blades 73 rotate, so that flowing wind is generated inside the air supply duct 63, and the wind blows in the direction of the concentrated cover 62, and the wind enters the concentrated cover 62 and blows inside the wind direction nozzle 64. Since the nozzle 64 has a small diameter, the wind flow rate entering the nozzle 64 is very fast, which is convenient for the liquid inside the liquid tank 61 to enter the inside of the nozzle 64 through the suction pipe 65, and under the action of the high-speed flowing air, it is convenient to blow away the liquid entering the nozzle 64 to form droplets, and since there are multiple nozzles 64 and suction pipes 65, it is convenient to form a droplet barrier inside the crushing frame 1 to prevent dust from rising, thereby preventing dust from drifting out from the feed port area of ​​the crushing device, thereby preventing the processing workshop environment from being polluted by dust and affecting the health of workers.

[0060] The rotation of the fan blades 73 facilitates the flow of air inside the air supply duct 63. When the dust flowing downward reaches the left bottom of the air supply duct 63, it enters the interior of the air supply duct 63 under the action of the air flow, and then reaches the area of ​​the filter frame 10, and is filtered by the filter frame 10. In this way, the dust can be further removed, thereby preventing more dust from overflowing from the left side of the conveying frame 3 and affecting the external environment. The filter frame 10 is provided with a plurality of filter holes, which can ensure that air passes through and retains dust, and prevent dust from entering the small-aperture nozzle 64 and causing the nozzle 64 to be blocked, thereby affecting the integrity of the droplet barrier, thereby improving the dust removal effect.

[0061] The output shaft of the first motor 72 rotates with the long rod 74, which can cause the first cam 81 to rotate. When the protruding end of the first cam 81 approaches and squeezes the movable plate 83, the top of the movable plate 83 moves toward the rear end along the mounting frame 71 to squeeze the bellows 82, thereby compressing the bellows 82, making it easier for the liquid inside the bellows 82 to enter the outlet pipe 84, then enter the nozzle 85 and be sprayed out from the nozzle 85, and then spray to the area of ​​the air supply duct 63 above the filter frame 10, so as to moisten the dust entering there, avoid dust scattering when the scraper 12 scrapes, thereby further facilitating the dust to enter the collection cover 11 for collection.

[0062] When the protruding end of the second cam 91 rotates to approach and squeeze the arc plate 95, the arc plate 95 moves with the moving rod 93 toward the direction of the exhaust pipe 92, so that the two piston plates 94 move, and the spring 96 is in a compressed state. When the two piston plates 94 move, the dust and impurities between the two piston plates 94 can be pushed into the interior of the exhaust pipe 92. As the moving rod 93 continues to move toward the direction of the exhaust pipe 92, when the piston plate 94 away from the second cam 91 passes through the interior of the exhaust pipe 92 and the piston plate 94 close to the second cam 91 is located inside the exhaust pipe 92 away from the second cam 91, the wet dust can be discharged.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
