Description

Technical Field

[0001] This invention relates to the field of coal screening and collection technology, and in particular to a coal screening and collection method and apparatus. Background Technology

[0002] Coal is the most abundant and widely distributed fossil fuel on Earth. The main elements that make up the organic matter of coal are carbon, hydrogen, oxygen, nitrogen, and sulfur, in addition to trace amounts of phosphorus, fluorine, chlorine, and arsenic.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention.

[0034] Example 1

[0035] Reference Figure 1 This is the first embodiment of the present invention, which provides a coal screening and collection method, including a method for coal feeding, screening and collection.

[0036] Specifically, the coal is fed into the system.

[0037] The screening component 102 screens the coal.

[0038] The transport component 202 intermittently feeds the screened coal;

[0039] The flipping component 203 quantitatively collects coal.

[0040] Furthermore, the screening component 102 screens the coal by starting the drive component 101 to drive the screening component 102 to reciprocate, thereby vibrating and screening the coal.

[0041] Furthermore, the intermittent feeding of the screened coal by the transport component 202 includes the drive component 101 driving the transmission component 201 to rotate intermittently, thereby driving the transport component 202 to transport the coal intermittently.

[0042] In summary, this invention, by setting up a method for coal feeding, screening, and collection, facilitates workers to quickly master the usage process, improves work efficiency, prevents equipment damage caused by operational errors, and protects the service life of the equipment.

[0043] Example 2

[0044] Reference Figures 2-8 This is the second embodiment of the present invention. This embodiment provides a coal screening and collection device, which includes a sorting unit 100, a conveying unit 200, and a feeding unit 300. By starting the drive component 101 to rotate, the screening component 102 is pushed to swing, so that the coal in the screening component 102 is evenly screened and falls into the top of the conveying component 202. The drive component 101 pushes the conveying component 202 to rotate intermittently, pushing the coal to move into the turning component 203. When the weight of the coal collected in the turning component 203 is greater than the pulling force of the reset component 204, the limit on the turning component 203 is released, and the turning component 203 turns over. Each time, the same weight of coal is turned over and transported, which is convenient for subsequent storage and use. After the coal is turned over and dumped, the weight disappears, and the reset component 204 pulls the turning component 203 to rotate back to the initial position to continue collecting the intermittently transported coal.

[0045] Specifically, the sorting unit 100 includes a drive assembly 101 and a screening assembly 102 disposed at the bottom of the drive assembly 101;

[0046] The conveying unit 200 includes a transmission assembly 201, a transport assembly 202 disposed on one side of the transmission assembly 201, a flipping assembly 203 disposed at the bottom of the transport assembly 202, and a reset assembly 204 fixedly connected to one side of the flipping assembly 203.

[0047] The feeding unit 300 includes a feeding component 301 and three sets of maintenance components 302 disposed on the top of the feeding component 301.

[0048] Furthermore, the feeding assembly 301 includes a feeding bin 301a, a feeding port 301b disposed on the top of the feeding bin 301a, a motor 301c disposed on one side of the feeding bin 301a, a rotating shaft 301d fixedly connected to one end of the motor 301c, a spiral pusher blade 301e disposed on one side of the rotating shaft 301d, and a discharging port 301f disposed at the bottom of the feeding bin 301a.

[0049] Furthermore, the maintenance assembly 302 includes a cover plate 302a, a fixing post 302b fixedly connected to the top of the cover plate 302a, a fixing sleeve rod 302c disposed on the top of the fixing post 302b, a fixing hole 302d disposed on one side of the fixing sleeve rod 302c, a rotating post 302e disposed on one side of the cover plate 302a, and a stop rod 302f fixedly connected to one side of the feeding bin 301a.

[0050] Furthermore, the fixed sleeve 302c is rotatably connected to the fixed column 302b, and the rotating column 302e is rotatably connected to the cover plate 302a.

[0051] Furthermore, the fixing post 302b is spring-connected to a fixing rod and is adapted to the fixing hole 302d, and the fixing sleeve rod 302c is adapted to the stop rod 302f.

[0052] Preferably, by pulling the fixing sleeve rod 302c, the cover plate 302a is driven to rotate around the rotating column 302e. After the cover plate 302a rotates 180 degrees, the fixing sleeve rod 302c rotates around the fixing column 302b, so that the fixing rod connected by the spring of the fixing column 302b is in a parallel position with the fixing hole 302d, thus fixing the fixing sleeve rod 302c. The stop rod 302f blocks and fixes the fixing sleeve rod 302c, which facilitates maintenance by maintenance personnel.

[0053] Furthermore, the drive assembly 101 includes a feed fixing plate 101a, two sets of L-shaped fixing columns 101b symmetrically arranged on both sides of the feed fixing plate 101a, a feed inlet 101c disposed on the top of the feed fixing plate 101a, a motor fixing block 101d fixedly connected to the bottom of the feed fixing plate 101a, a drive motor 101e disposed on one side of the motor fixing block 101d, a drive rod 101f disposed on one side of the drive motor 101e, four sets of first inclined fixing plates 101g symmetrically arranged on both sides of the feed fixing plate 101a, a first fixing column 101h fixedly connected to one side of the first inclined fixing plate 101g, and a flexible fixing plate 101i fixedly connected to one side of the first fixing column 101h.

[0054] The screening assembly 102 includes a screening plate 102a, a plurality of screening holes 102b disposed on one side of the screening plate 102a, a second inclined fixing plate 102c symmetrically disposed on both sides of the screening plate 102a, a second fixing column 102d fixedly connected to one side of the second inclined fixing plate 102c, a push rod 102e fixedly connected to one side of the screening plate 102a, a push sleeve rod 102f fixedly connected to one end of the push rod 102e, and a rotating protrusion 102g fixedly connected to one side of the push sleeve rod 102f.

[0055] Preferably, coal is poured into the top of the screening plate 102a through the feed inlet 101c. The drive motor 101e is started to drive the drive rod 101f to rotate, which in turn drives the fixed rotating protrusion 102g to rotate rapidly. Under the rotation of the rotating protrusion 102g, the push sleeve 102f pushes and pulls the push rod 102e around the rotating protrusion 102g, causing the screening plate 102a to move the second inclined fixed plate 102c. The second inclined fixed plate 102c pushes the fixed flexible fixed plate 101i to vibrate back and forth. The flexible fixed plate 101i is fixed and stabilized by the first inclined fixed plate 101g at the top, supporting the screening plate 102a. The bottom swings under the push of the second inclined fixed plate 102c, causing the screening plate 102a to swing and quickly screen the coal. The top feed fixed plate 101a is supported by two sets of L-shaped fixed columns 101b to maintain stability.

[0056] Furthermore, the transmission assembly 201 includes a first belt drive ring 201a, a transmission belt 201b disposed on one side of the first belt drive ring 201a, a second belt drive ring 201c disposed at the bottom of the first belt drive ring 201a, a transmission shaft 201d fixedly connected to one end of the second belt drive ring 201c, two sets of transmission plates 201e symmetrically disposed on both sides of the transmission shaft 201d, a limiting ring 201f fixedly connected to one end of the transmission plate 201e, and a lever 201g fixedly connected to one side of the transmission shaft 201d;

[0057] The transport assembly 202 includes a rotating shaft 202a, a rotating disk 202b fixedly connected to one end of the rotating shaft 202a, several sets of rotating rods 202c fixedly connected to one side of the rotating disk 202b, a conveyor belt 202d fixedly connected to one side of the rotating shaft 202a, and four sets of support legs 202e disposed at the bottom of the conveyor belt 202d.

[0058] The flipping assembly 203 includes two sets of supporting vertical plates 203a, a fixed shaft 203b fixedly connected to one side of each of the two sets of supporting vertical plates 203a, a rotating sleeve rod 203c rotatably connected to the middle of the fixed shaft 203b, a trapezoidal collection chamber 203d fixedly connected to the top of the rotating sleeve rod 203c, a limiting load-bearing groove 203e provided on one side of the trapezoidal collection chamber 203d, a threaded rod 203f provided on one side of the trapezoidal collection chamber 203d, a limiting plate 203g fixedly connected to one side of the trapezoidal collection chamber 203d, a counterweight block 203h threadedly connected to one end of the threaded rod 203f, and a rotating frame 203i provided at one end of the threaded rod 203f.

[0059] Preferably, rotating the rotating frame 203i drives the threaded rod 203f, which is rotatably connected to the limiting plate 203g, to rotate. This causes the counterweight block 203h, which is threaded to one end of the threaded rod 203f, to move to one side along the limiting load-bearing groove 203e under the limitation of the limiting rod fixed to one side. Adjusting the position of the counterweight block 203h causes the center of gravity of the trapezoidal collection bin 203d to shift. This allows the coal ash collected in the trapezoidal collection bin 203d to be collected by deflection based on the weight state of the coal ash collected in the trapezoidal collection bin 203d, thus enabling precise collection of the quantity each time.

[0060] The reset assembly 204 includes a support rod 204a, a telescopic sleeve 204b fixedly connected to the top of the support rod 204a, a telescopic rod 204c spring-connected to one side of the telescopic sleeve 204b, a rotating groove 204d disposed at one end of the telescopic rod 204c, a rotating shaft 204e fixedly connected to both sides of the rotating groove 204d, a rotating sleeve 204f rotatably connected to the rotating shaft 204e, a fixed limiting groove 204g disposed on one side of the telescopic sleeve 204b, and a fixing block 204h spring-connected to one side of the telescopic rod 204c.

[0061] Preferably, the drive rod 101f drives the first belt drive ring 201a to rotate, and the transmission belt 201b pulls the second belt drive ring 201c to drive the fixedly connected transmission shaft 201d to rotate. The two sets of transmission plates 201e fixedly connected to both sides of the transmission shaft 201d drive the limiting ring 201f to rotate. The limiting ring 201f limits a set of rotating rods 202c. When the limiting ring 201f rotates to the point where the rotating rods 202c are in the opening position, the limiting of the rotating rods 202c is released. The actuating rod 201g contacts a set of rotating rods 202c and pushes the rotating rods 202c to rotate a distance between the set of rotating rods 202c. The limiting ring 201f limits the next set of rotating rods 202c, thus preventing rapid rotation under inertia that would cause the conveyor belt 202d to move rapidly and result in uneven coal conveying.

[0062] It should be noted that one side of the second fixed column 102d is fixedly connected to one side of the flexible fixed plate 101i, the rotating protrusion 102g is fixedly connected to one end of the drive rod 101f, the push sleeve 102f is set in an inclined state, one end of the transmission shaft 201d is rotatably connected to one side of the conveyor belt 202d, one end of the two sets of transmission plates 201e is fixedly connected to one side of the transmission shaft 201d, the rotating rod 202c is adapted to the actuating rod 201g, the rotating rod 202c is adapted to the limiting ring 201f, the trapezoidal collection bin 203d is set at the bottom of the conveyor belt 202d, one end of the rotating sleeve 204f is fixedly connected to one side of the trapezoidal collection bin 203d, one side of the fixed block 204h is set as an arc surface, and one side of the fixed limiting groove 204g is set as... The curved surface of the fixed block 204h is adapted to the curved surface of the fixed limiting groove 204g. The diameter of the second belt drive ring 201c is larger than that of the first belt drive ring 201a. The drive rod 101f rotates faster. The larger diameter of the second belt drive ring 201c than that of the first belt drive ring 201a allows the transmission shaft 201d to rotate at a speed lower than that of the drive rod 101f. One side of the limiting ring 201f is provided with an opening. The actuating rod 201g is provided in the opening. The length of the actuating rod 201g is the same as the radius of the limiting ring 201f. It can contact the rotating rod 202c and push the rotating rod 202c to rotate. One side of the trapezoidal collection bin 203d is inclined inward and the other side is inclined outward.

[0063] In use, this invention has a total of 100 usage processes. In the first usage process, the feeding assembly 301 is inspected. By pulling the fixing sleeve rod 302c, the cover plate 302a is driven to rotate around the rotating column 302e. After the cover plate 302a rotates 180 degrees, the fixing sleeve rod 302c is rotated around the fixing column 302b, so that the fixing rod connected by the spring of the fixing column 302b is in a parallel position with the fixing hole 302d, and the fixing sleeve rod 302c is fixed. The stop rod 302f blocks and fixes the fixing sleeve rod 302c, which facilitates the inspection by maintenance personnel.

[0064] In the second usage process, the coal is screened. The coal is poured into the top of the screening plate 102a through the feed inlet 101c. The drive motor 101e is started to drive the drive rod 101f to rotate, which in turn drives the fixed rotating protrusion 102g to rotate rapidly. Under the rotation of the rotating protrusion 102g, the push sleeve 102f pushes and pulls the push rod 102e around the rotating protrusion 102g, causing the screening plate 102a to move the second inclined fixed plate 102c. The second inclined fixed plate 102c pushes the fixed flexible fixed plate 101i to vibrate back and forth. The flexible fixed plate 101i is fixed and stabilized by the first inclined fixed plate 101g at the top, supporting the screening plate 102a. The bottom swings under the push of the second inclined fixed plate 102c, causing the screening plate 102a to swing and quickly screen the coal. The top feed fixed plate 101a is supported by two sets of L-shaped fixed columns 101b to keep it stable.

[0065] In the third usage process, coal is intermittently conveyed. The drive rod 101f drives the first belt drive ring 201a to rotate, which in turn pulls the second belt drive ring 201c via the transmission belt 201b, causing the fixedly connected transmission shaft 201d to rotate. The two sets of transmission plates 201e, which are fixedly connected to both sides of the transmission shaft 201d, drive the limiting ring 201f to rotate. The limiting ring 201f limits a set of rotating rods 202c. When the limiting ring 201f rotates to the point where the rotating rods 202c are in the open position, the limitation on the rotating rods 202c is released. The actuating rod 201g contacts a set of rotating rods 202c and pushes the rotating rods 202c to rotate a distance between sets of rotating rods 202c. The limiting ring 201f then limits the next set of rotating rods 202c to prevent rapid rotation due to inertia, which would cause the conveyor belt 202d to move rapidly and result in uneven coal conveying.

[0066] In the fourth process, coal is collected. The conveyor belt 202d intermittently transports the uniformly screened coal to the trapezoidal collection bin 203d. As the amount of coal increases, the weight on the trapezoidal collection bin 203d gradually increases, pulling the telescopic rod 204c to one side. The telescopic rod 204c is within the fixed limiting groove 204g of the fixed block 204h and remains stationary under the tension of the spring. When the trapezoidal collection bin 203d is full, the gravity is greater than the spring tension, pulling the telescopic rod 204c. The arc-shaped surface on one side of the fixed block 204h and the matching arc-shaped surface on the side of the fixed limiting groove 204g squeeze each other, causing the fixed block 204h to contract and release the pressure on the telescopic rod 204c. When the limit of c moves to one side, the rotating sleeve 204f rotates 90 degrees around the rotating axis 204e in the rotating groove 204d, and the coal in the trapezoidal collection bin 203d is poured out. The amount of coal poured out each time is the same, which is convenient for subsequent storage and use. After the coal is poured out, the tension caused by gravity decreases, and the deformed spring pulls the telescopic rod 204c back to the initial position. The rotating sleeve 204f rotates 90 degrees in the opposite direction around the rotating axis 204e in the rotating groove 204d and returns to the initial position. When the fixed block 204h moves to be parallel with the fixed limit groove 204g, the spring pushes the fixed block 204h into the fixed limit groove 204g to limit and fix the telescopic rod 204c.

[0067] In summary, this invention, by setting up a sorting unit, a conveying unit, and a feeding unit, activates a drive component to drive a screening component to swing, filtering and screening the coal. This drives a transmission component to rotate, pushing a transport component to intermittently transport the coal, ensuring that the coal is uniformly screened and then conveyed to a tilting component. When the weight of the coal accumulates to exceed the pulling force of the reset component, it contacts the limit of the reset component and tilts, ensuring that the same weight of coal is poured in. After the coal is poured out, the tilting component returns to its initial position under the pull of the reset component, collecting the coal for subsequent use in the coal storage box. This saves the labor intensity of the staff, improves work efficiency, and facilitates the maintenance of the feeding component in case of failure.
