Description

Technical Field

[0001] This invention belongs to the field of coal processing technology, specifically a coal processing feeding method and feeding device. Background Technology

[0002] Coal is a combustible black or brownish-black sedimentary rock, which can generally be found in coal deposits or coal seams. The organic matter in coal is mainly composed of five elements: carbon, hydrogen, oxygen, nitrogen, and organic sulfur. It can be burned to generate electricity and heat, so coal is one of the most important energy sources.

[0003] After coal is mined, it needs to be further processed before it can be used. Generally, a feeding device is used to feed the coal from the storage bin to the receiving device evenly and continuously, so as to realize the feeding during coal processing and facilitate subsequent processing.

[0004] When feeding coal, a vibrating motor drives the feeding trough to perform periodic linear reciprocating vibration along the inclined direction. When the vertical acceleration component of the vibration of the feeding trough is greater than the acceleration due to gravity, the material in the trough will be thrown up and jump forward along a parabolic trajectory to achieve the purpose of feeding. However, since the current coal feeding device is only used for feeding materials, large pieces of coal fall into the feeding trough and accumulate with small pieces of coal, which affects the efficiency of the vibration feeding of coal.

[0005] Therefore, the present invention provides a coal processing feeding method and feeding device. Summary of the Invention

[0014] Preferably, a heater is fixedly connected to the top of the shield; a pump pipe is fixedly connected to the output end of the heater; and a sensor is installed on the inner wall of the shield, and multiple sensors are provided.

[0015] Preferably, a water tank is fixedly connected to the outside of the fixing plate and the shielding plate; a pump pipe is fixedly connected to the inside of the water tank via a water pump; an atomizing nozzle is fixedly connected to the end of the pump pipe away from the water tank; a conduit is connected between the pump pipe and the steam nozzle, and a solenoid valve is installed on the conduit.

[0016] A coal processing feeding method, applicable to the coal processing feeding device described above, comprises the following steps:

[0017] S1: When feeding coal, the coal is first poured in from the feed port of the baffle plate. The coal extrusion baffle rotates and presses the coal into the feeder body. The output end of the servo motor drives the rotating rod to rotate synchronously. Multiple striking blocks and needle blocks work together to crush the coal blocks. The splashed coal can hit the crushed blocks for continuous crushing.

[0018] S2: After the coal is crushed, the vibrating motor drives the feeder body to vibrate as a whole. The filter screen vibrates synchronously to filter the crushed coal. The rotating shaft scrapes the surface of the filter screen as the rotating rod rotates. The fallen coal pieces can enter the detection chamber. The electric slider drives the detection head on the side of the sliding plate to slide, and works with the sealing plate and screen to seal the coal pieces. The detection head detects the moisture content in the coal pieces.

[0019] S3: After detecting the moisture content of the crushed coal, if the moisture content is high, the heater is turned on to heat it, and steam is sprayed from the steam nozzle to dry the coal. If the moisture content is too low, a small amount of water is drawn from the water tank and sprayed into the atomizing nozzle to reduce dust at the crushing point of the coal. Finally, the crushed coal is filtered and falls to the bottom of the feeder body, where it is continuously vibrated by the vibration motor to transport the coal inside the feeder body.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The coal processing feeding method and feeding device of the present invention filters large pieces of coal through a filter screen, and uses multiple vibrating motors to assist the filter screen in vibrating, reducing the impact of large pieces of coal on the conveying and feeding process. Multiple striking blocks and needle-punching blocks are used to impact and crush large pieces of coal. A baffle plate blocks the flying coal, and some of the flying coal impacts the crushing blocks, which plays a role in secondary crushing of the coal. A rotating shaft is driven to rotate by a rotating rod and a gear set, and a scraper is used to scrape the surface of the filter screen to improve the filtration effect of the filter screen. A baffle plate is installed on the inner wall of the baffle plate with the rotating roller to block and discharge floating dust.

[0022] 2. The coal processing feeding method and feeding device of the present invention uses multiple detection heads to sample and test a portion of the coal to detect the moisture content. A sealing plate and a screen are used to seal the detection chamber to improve the accuracy of coal moisture detection. A heater is used to heat the water in the steam nozzle, and the steam is sprayed out of the steam nozzle to dry the coal inside the baffle plate. Water is pumped from the water tank to the atomizing nozzle for spraying, which humidifies and reduces dust in the coal. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 2 As shown in the embodiment of the present invention, a coal processing feeding device includes a feeding body 1; both sides of the feeding body 1 are fixedly connected to a suspension hook 11 and a vibration motor 12, and multiple suspension hooks 11 and vibration motors 12 are provided; a fixing plate 13 is fixedly connected to the inside of the feeding body 1; a filter screen plate 14 is fixedly connected to the bottom end of the fixing plate 13, and the filter screen plate 14 is connected to the inner wall of the feeding body 1; a crushing component is provided inside the feeding body 1, which is used to crush large pieces of coal; when feeding coal, the feeding device is first assembled and suspended by multiple suspension hooks 11 on the outside of the feeding body 1, and an elastic support seat can also be provided at the bottom end of the feeding body 1. The feeder body 1 is installed at an angle, and coal is poured into the interior of the feeder body 1. The coal falls between the fixed plate 13 and the inner wall of the feeder body 1, and is located at the top of the filter screen plate 14. As multiple vibration motors 12 work and vibrate, they drive the filter screen plate 14 to vibrate synchronously to filter the coal. Large pieces of coal will be filtered onto the filter screen plate 14 and then crushed by the crushing component. The filtered fine coal falls to the bottom of the interior of the feeder body 1, where multiple vibration motors 12 drive the feeder body 1 to vibrate, thereby conveying the fine coal and reducing the impact of large pieces of coal on the feeding process. At the same time, the multiple vibration motors 12 drive the filter screen plate 14 to vibrate synchronously, improving the filtration effect of the filter screen plate 14.

[0032] like Figures 1 to 3As shown, the crushing assembly includes a servo motor 2, a rotating rod 21, striking blocks 22, and needle-piercing blocks 23. The servo motor 2 is fixedly connected to the outside of the feeder body 1. The rotating rod 21 is rotatably connected to the inside of the feeder body 1, and one end of the rotating rod 21 is connected to the output end of the servo motor 2. Multiple striking blocks 22 are fixedly connected to the outside of the rotating rod 21. Multiple needle-piercing blocks 23 are fixedly connected to the outside of the striking blocks 22. When the filter screen 14 filters out large pieces of coal that are difficult to feed, the output end of the servo motor 2 drives the rotating rod 21 to rotate synchronously and quickly. Multiple striking blocks 22 rapidly impact the large pieces of coal, and multiple needle-piercing blocks 23 on the striking blocks 22 crush the large pieces of coal, thereby achieving the effect of crushing large pieces of coal, so that it can be vibrated and fed from the filter screen 14.

[0033] like Figures 1 to 2 As shown, a baffle plate 3 is fixedly connected to the top of the feeder body 1 and the fixed plate 13; the inner wall of one side of the baffle plate 3 has an arc-shaped cross section; a crushing block 31 is fixedly connected to the arc-shaped inner wall of the baffle plate 3; when crushing large pieces of coal, the striking block 22 rotates rapidly to impact the coal, which easily knocks the falling coal away. By using the baffle plate 3 fixed above the filter screen plate 14, and relying on the slope above the arc-shaped cross section of the baffle plate 3, the coal can be guided to fall to the striking block 22 for crushing. The splashed coal will be blocked by the baffle plate 3, reducing the situation of coal splashing. Some of the knocked-away coal can impact multiple crushing blocks 31 a second time, achieving the effect of secondary crushing of the coal.

[0034] like Figures 1 to 3 As shown, a fixed frame 4 is fixedly connected to the inner wall of the feeder body 1; a gear box 41 is fixedly connected to the side of the fixed frame 4 away from the feeder body 1; a rotating shaft 42 is rotatably connected to the top of the filter screen plate 14, and multiple rotating shafts 42 are provided; a gear set is provided inside the gear box 41, and the rotating shaft 42 is connected to the rotating rod 21 through the gear set; a scraper 43 is fixedly connected to the outside of the rotating shaft 42, and the scraper 43 is attached to the top of the filter screen plate 14; when the filter screen plate 14 filters out a large amount of coal pile When the surface area affects filtration, the gear box 41 is fixed to the outside of the rotating rod 21 using the fixing frame 4. The gear box 41 is used to protect the gear set. When the rotating rod 21 rotates, it drives two meshing bevel gears to rotate. One bevel gear is installed on the rotating rod 21, while the other bevel gear is installed at the top of the rotating shaft 42. The rotating shaft 42 rotates with the rotating rod 21, driving the scraper 43 to scrape the surface of the filter screen plate 14, reducing the accumulation of coal on the surface of the filter screen plate 14 and improving the filtration effect of the filter screen plate 14.

[0035] like Figures 1 to 2As shown, the inner wall of the baffle plate 3 is rotatably connected to the rotating roller 5 via a torsion spring, and the rotating roller 5 is located above the arc-shaped cross section; a baffle plate 51 is fixedly connected to the outside of the rotating roller 5; when a large amount of coal is crushed, dust is easily generated and floats outward. The baffle plate 51 is installed on the inner wall of the baffle plate 3 in conjunction with the rotating roller 5 to block the coal feed port at the baffle plate 3, reducing the dust from floating outward. When the coal is fed, the coal can squeeze the baffle plate 51 to rotate with the rotating roller 5. The baffle plate 51 can fan some of the floating dust into the baffle plate 3. The torsion spring is stressed, and the coal is pressed into the striking block 22 and crushed. The torsion spring drives the baffle plate 51 on the rotating roller 5 to rotate and reset, continuing to block the floating dust.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, a detection chamber 6 is provided inside the feeder body 1 on one side of the bottom end of the filter screen plate 14; an electric slider 61 is slidably connected inside the feeder body 1 near the detection chamber 6; a sliding plate 62 is fixedly connected to the outside of the electric slider 61; a detection head 63 is fixedly connected to the side of the sliding plate 62 away from the electric slider 61, and multiple detection heads 63 are provided; when a portion of the coal is sampled for moisture content testing, the electric slider 61 drives the sliding plate 62 to slide towards the detection chamber 6, and multiple detection heads 63 penetrate into the detection chamber 6. The coal filtered on the filter screen plate 14 is fed into the detection chamber 6, and a portion of the coal is received by the multiple detection heads 63. Then, the moisture content of the coal is tested. If the moisture content exceeds the set range, an alarm is triggered, which is convenient for workers to check and operate.

[0037] The sliding plate 62 is fixedly connected to both sides of the detection head 63 with a blocking plate 7 and a screen 71. The blocking plate 7 is located below the screen 71. When sampling and testing a portion of the coal, the sliding plate 62 is driven to slide by the electric slider 61, which simultaneously drives the blocking plate 7 and the screen 71 to slide to the detection chamber 6. The blocking plate 7 can temporarily block and store the coal fed into the detection chamber 6, while the screen 71 filters out fine coal that falls to multiple detection heads 63. The fine coal wraps around multiple detection heads 63, improving the accuracy of the sampling and testing by the detection head 63.

[0038] like Figures 1 to 2 As shown, a heater 8 is fixedly connected to the top of the baffle plate 3; a pump pipe 91 is fixedly connected to the output end of the heater 8; a sensor 82 is installed on the inner wall of the baffle plate 3, and multiple sensors 82 are provided; when the sampling detects that the moisture content of the coal is too high, or when multiple sensors 82 detect that there is too much moisture inside the baffle plate 3, the heater 8 is used to heat the water inside the steam nozzle 81, and steam is sprayed from the steam nozzle 81 into the interior of the baffle plate 3, which serves to dry the coal inside the baffle plate 3 with steam.

[0039] A water tank 9 is fixedly connected to the outside of the fixed plate 13 and the shielding plate 3; a pump pipe 91 is fixedly connected to the inside of the water tank 9 via a water pump; an atomizing nozzle 92 is fixedly connected to the end of the pump pipe 91 away from the water tank 9; a conduit is connected between the pump pipe 91 and the steam nozzle 81, and a solenoid valve is installed on the conduit; when the sampling test shows that the moisture content of the coal is low, or when multiple sensors 82 detect that the moisture content inside the shielding plate 3 is too low, the coal is prone to cause a large amount of dust to float after being broken. Water is pumped from the inside of the water tank 9 and transported to the atomizing nozzle 92 by the pump pipe 91 for atomization and spraying, which plays a role in humidifying and reducing dust in the coal inside the shielding plate 3. At the same time, when the water in the steam nozzle 81 is too low, the solenoid valve can be opened, and the conduit transports some water into the steam nozzle 81 for heating, which plays a role in automatically adding water to the steam nozzle 81.

[0040] like Figure 5 As shown, a coal processing feeding method is applicable to the coal processing feeding device described above. The steps of the method are as follows:

[0041] S1: When feeding coal, the coal is first poured in from the feed inlet of the baffle plate 3. The coal extrusion baffle 51 rotates and presses into the inside of the feeder body 1. The output end of the servo motor 2 drives the rotating rod 21 to rotate synchronously. Multiple striking blocks 22 work with needle blocks 23 to crush the coal blocks. The splashed coal can hit the crushing block 31 for continuous crushing.

[0042] S2: After the coal is crushed, the vibrating motor 12 drives the feeder body 1 to vibrate as a whole. The filter screen 14 vibrates synchronously to filter the crushed coal. The rotating shaft 42 scrapes the surface of the filter screen 14 as the rotating rod 21 rotates. The fallen coal fragments can enter the detection chamber 6. The electric slider 61 drives the detection head 63 on the side of the sliding plate 62 to slide, and cooperates with the sealing plate 7 and the screen 71 to seal the coal fragments. The detection head 63 detects the moisture content in the coal fragments.

[0043] S3: After detecting the moisture content of the crushed coal, if the moisture content is high, the heater 8 is turned on to heat it, and steam is sprayed from the steam nozzle 81 to dry the coal. If the moisture content is too low, the water tank 9 is turned on to extract a small amount of water to the atomizing nozzle 92 for atomization and spraying to reduce dust at the crushed part of the coal. Finally, the crushed coal is filtered and falls to the bottom of the feeder body 1. The vibrating motor 12 continuously vibrates to transport the coal inside the feeder body 1.

[0044] During operation, when feeding coal, the feeding device is first assembled and suspended by multiple hooks 11 on the outside of the feeder body 1. A flexible support seat is also provided at the bottom of the feeder body 1. The feeder body 1 is installed at an angle, and coal is poured into its interior. The coal falls between the fixed plate 13 and the inner wall of the feeder body 1, and is located at the top of the filter screen plate 14. As multiple vibration motors 12 work and vibrate, the filter screen plate 14 vibrates synchronously to filter the coal. Large pieces of coal are filtered onto the filter screen plate 14 and then crushed by the crushing component. The filtered fine coal falls back onto the feeder body. At the bottom of the inside of the feeder body 1, multiple vibration motors 12 drive the feeder body 1 to vibrate, thereby conveying and feeding fine coal and reducing the impact of large coal pieces on the feeding process. At the same time, multiple vibration motors 12 drive the filter screen 14 to vibrate synchronously, improving the filtration effect of the filter screen 14. When the filter screen 14 filters out large coal pieces that are difficult to pass, the output end of the servo motor 2 drives the rotating rod 21 to rotate synchronously and quickly. Multiple striking blocks 22 rapidly impact the large coal pieces, and multiple needle-like blocks 23 on the striking blocks 22 crush the large coal pieces, achieving the effect of pulverizing the large coal pieces, so that they can be vibrated and discharged from the filter screen 14.

[0045] When crushing large pieces of coal, the striking block 22 rotates rapidly to impact the coal, easily knocking the falling coal away. By fixing the baffle plate 3 above the filter screen 14, the slope above the arc-shaped cross-section of the baffle plate 3 can guide the coal to fall to the striking block 22 for crushing. The splashed coal is blocked by the baffle plate 3, reducing the amount of coal splashing. Some of the knocked-away coal can impact multiple crushing blocks 31 a second time, achieving the effect of secondary crushing of the coal. When the filter screen 14 filters out a large amount of coal that accumulates on the surface and affects filtration, the gear box 41 is fixed to the outside of the rotating rod 21 by the fixing frame 4. The gear box 41 is used to protect the gear set. When the rotating rod 21 rotates, it drives two meshing bevel gears to rotate. One bevel gear is installed on the rotating rod 21, and the other bevel gear is installed at the top of the rotating shaft 42. The rotating shaft 42 rotates with the rotating rod 21, driving the scraper 43 to scrape the surface of the filter screen 14, reducing the accumulation of coal on the surface of the filter screen 14 and improving the filtration effect of the filter screen 14.

[0046] When a large amount of coal is crushed, dust is easily generated and floats outward. The baffle plate 51 is installed on the inner wall of the shield plate 3 in conjunction with the rotating roller 5 to block the coal feed port at the shield plate 3, reducing the dust from floating outward. When the coal is fed, the coal can squeeze the baffle plate 51 to rotate with the rotating roller 5. The baffle plate 51 can fan some of the floating dust into the shield plate 3. When the torsion spring is stressed, the coal is pressed into the striking block 22 and crushed. The torsion spring drives the baffle plate 51 on the rotating roller 5 to rotate and reset, continuing to block the floating dust.

[0047] When sampling and testing the moisture content of a portion of the coal, the electric slider 61 drives the sliding plate 62 to slide towards the detection chamber 6. Multiple detection heads 63 penetrate into the detection chamber 6. Coal filtered on the filter screen 14 is fed into the detection chamber 6, where multiple detection heads 63 receive a portion of the coal. The moisture content of the coal is then tested, and an alarm is triggered if the moisture content exceeds the set range, facilitating worker inspection and operation. When sampling and testing a portion of the coal, the electric slider 61 drives the sliding plate 62 to slide, simultaneously driving the sealing plate 7 and the screen 71 to slide towards the detection chamber 6. The sealing plate 7 can temporarily block and store the coal fed into the detection chamber 6, while the screen 71 filters out fine coal particles that fall to the multiple detection heads 63. The fine coal particles envelop the multiple detection heads 63, improving the accuracy of the sampling and testing by the detection heads 63.

[0048] When the sampling detects that the moisture content of the coal is too high, or when multiple sensors 82 detect that there is too much moisture inside the baffle plate 3, the heater 8 is used to heat the water inside the steam nozzle 81, and steam is sprayed from the steam nozzle 81 into the baffle plate 3 to dry the coal inside the baffle plate 3.

[0049] When sampling detects that the moisture content of the coal is low, or when multiple sensors 82 detect that the moisture content inside the baffle plate 3 is too low, the coal is prone to causing a large amount of dust to float after it is broken. Water is pumped from inside the water tank 9 and transported to the atomizing nozzle 92 through the pump pipe 91 for atomization and spraying, which can humidify and reduce dust in the coal inside the baffle plate 3. At the same time, when the water in the steam nozzle 81 is too low, the solenoid valve can be opened, and the conduit can transport some water into the steam nozzle 81 for heating, which can automatically add water to the steam nozzle 81.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

S3: After detecting the moisture content of the crushed coal, if the moisture content is high, turn on the heater (8) to heat it, and steam will be sprayed from the steam nozzle (81) to dry the coal. If the moisture content is too low, turn on the water tank (9) to draw a small amount of water to the atomizing nozzle (92) for atomization spraying, and dust suppression treatment will be carried out on the crushed coal. Finally, the crushed coal is filtered and falls to the bottom of the feeder body (1). The vibrating motor (12) continuously vibrates to transport the coal inside the feeder body (1).
