Description

Technical Field

[0001] This invention relates to the field of sample coal screening and packaging technology, and in particular to a sample coal screening and packaging device. Background Technology

[0002] In the coal-fired power plant production process, fuel costs account for approximately 80% of the total cost. Coal is an important source of energy and industrial raw materials. The coal quality parameters of different coal types, such as ash content, volatile matter, fixed carbon, and calorific value, have a significant impact on energy, combustion characteristics, and industrial production processes. Therefore, ensuring the quality and stability of coal fed into the furnace is of great significance for maintaining the economic benefits of the power plant. Thus, accurate coal quality analysis is crucial for assessing coal quality, optimizing supply chain management, and ensuring the stability of the production process.

[0003] The sampling and collection of coal entering the furnace, through the rational design and use of processes such as spiral mixing and automatic packaging, has reduced the labor intensity of sampling personnel. However, when packaging the coal samples, it is necessary to screen them and control the overall size of the coal samples sent for testing within a certain range to meet the needs of subsequent coal processing steps or experiments. Furthermore, during the subsequent packaging process, the weight of the packaged coal samples may be inconsistent, which can easily lead to errors during the sampling process, making the uniformity of the sampling unstable and causing certain deviations in the subsequent coal quality analysis results.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] 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. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a sample coal screening and packaging device. The first worm gear C is driven to rotate by a motor, which in turn drives the first turbine C-1 to rotate, causing the transmission rod G-4 to reciprocate. This causes the screening plate G to vibrate above the transport plate Z, thereby screening and separating the sample coal.

[0033] Specifically, the vibrating screening component D includes a conveyor plate Z, a coal hopper Z-1 disposed on the outer wall of the conveyor plate Z, a screening plate G disposed at the end of the conveyor plate Z, and a first worm gear C disposed at the end of the conveyor plate Z.

[0034] The first worm gear C is located at the bottom of the conveyor plate Z. The rotation of the first worm gear C drives the screening plate G to vibrate and screen the coal sample on the conveyor plate Z. The composite coal sample passes through the screening plate G and enters the conveyor plate Z. The conveyor plate Z transports the screened coal sample and it falls into the coal hopper below.

[0035] Preferably, the coal hopper Z-1 is disposed on the outer wall of the conveying plate Z, and the coal hopper Z-1 is disposed above the coal conveying hopper. The end of the conveying plate Z is provided with a limit guide rail Z-2, and the end of the conveying plate Z is provided with an installation plate Z-3. The end face of the installation plate Z-3 is provided with a limit groove Z-4.

[0036] Among them, the coal hopper Z-1 is set on the side of the conveying plate Z, extending obliquely to the inside and above the coal hopper. A limiting guide rail Z-2 is set on the bottom surface of the conveying plate Z. The transmission plate G-2 moves back and forth along the limiting guide rail Z-2 to prevent deviation. At the same time, the two arms of the transmission plate G-2 pass through the limiting slide groove Z-4 ​​on the side wall of the mounting plate Z-3, fold up to the top of the mounting plate Z-3 and connect to the screening plate G, driving the screening plate G to move back and forth.

[0037] The outer wall of the screening plate G is provided with a coal return hole G-1, the outer wall of the screening plate G is provided with a transmission plate G-2, the end face of the transmission plate G-2 is provided with a limit hole G-3, the outer wall of the transmission plate G-2 is provided with a transmission rod G-4, the end of the transmission rod G-4 is provided with a transmission block G-5, and the outer wall of the transmission rod G-4 is fitted with a limit plate G-6.

[0038] The coal return hole G-1 is located on the side of the screening plate G, opposite to the direction of the coal hopper Z-1. Unqualified sample coal is discharged from the coal return hole G-1 above the screening plate G, without affecting the subsequent screening of sample coal. The transmission plate G-2 has a limiting hole G-3 in the middle, which is fitted above the limiting guide rail Z-2, allowing the transmission plate G-2 to move back and forth on the limiting guide rail Z-2. The transmission rod G-4 is located on both sides of the transmission plate G-2, and is driven by the transmission block G-5 at the head of the transmission plate G-2. The limiting plate G-6 is fitted outside the transmission rod G-4, and the other side of the limiting plate G-6 is connected to the transport plate Z, limiting the movement of the transmission rod G-4.

[0039] Preferably, the outer wall of the first worm gear C is engaged with a first turbine C-1, the outer wall of the first turbine C-1 is provided with a reciprocating groove C-2, the first turbine C-1 is disposed at the end of the transmission rod G-4, and the end of the transmission block G-5 extends to the inner wall of the reciprocating groove C-2 and slides therewith.

[0040] The first turbine C-1 is fixed to the bottom surface of the transport plate Z. The side of the first turbine C-1 extends into the groove at the top of the transmission rod G-4. The transmission block G-5 in the groove at the top of the transmission rod G-4 slides in the reciprocating groove C-2, driving the transmission rod G-4 to move back and forth, thereby driving the screening plate G above to screen the sample coal above the transport plate Z.

[0041] In summary, during operation, the motor drives the first worm gear C to rotate, causing the first turbine C-1, which meshes on both sides, to rotate below the conveyor plate Z. When the first turbine C-1 rotates, the transmission block G-5 slides within the reciprocating groove C-2 on the end face of the first turbine C-1, driving the transmission rod G-4 to reciprocate within the limiting plate G-6. This, in turn, causes the transmission plate G-2 to move outside the limiting guide rail Z-2. The transmission plate G-2 then drives the upper screening plate G to move above the conveyor plate Z, screening the coal sample. The qualified coal falls onto the conveyor plate Z and enters the coal hopper through the coal drop hopper Z-1 for subsequent packaging. The unqualified coal sample is discharged through the coal return hole G-1 on the side of the screening plate G.

[0042] Example 2

[0043] Reference Figure 1 , Figure 4 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in this embodiment, the material box drives the bearing plate 101a to press down, which drives the pusher 201 to push the new material box onto the bearing plate 101a, and at the same time drives the locking member 204 above to lock the rubber pipe.

[0044] Specifically, the main component 100 includes a weighing shell 101, a transport shell 102 disposed on the outer wall of the weighing shell 101, and a fixing shell 103 disposed at the end of the weighing shell 101; and,

[0045] The pushing assembly 200 includes a pushing member 201 disposed inside the transport housing 102, a transmission member 202 disposed inside the weighing housing 101, a moving member 203 disposed inside the fixed housing 103, and a locking member 204 disposed on the outer wall of the moving member 203.

[0046] The transport shell 102 is located on the side of the weighing shell 101. After the material box placed on the weighing shell 101 has collected a certain weight, it will be squeezed out by the empty material box on the transport shell 102. The sample coal above will continue to be collected through the empty material box. The fixing shell 103 is located above the weighing shell 101 and is located on the outer ring of the banana pipe. The locking part 204 inside the fixing shell 103 can lock the soft material pipe and prevent the sample coal from falling after the material box below is full.

[0047] The pusher 201 is located inside the transport shell 102. When the weight of the sample coal in the material box on the support plate 101a reaches a certain amount, it will drive the pusher 201 to move. At the same time, the transmission component 202 drives the locking component 204 in the fixed shell 103 to clamp the rubber pipe, so that the sample coal can no longer fall. The pusher 201 pushes the new material box into the support plate 101a, and squeezes the full material box into the side conveyor belt, which then transports the material box away.

[0048] Preferably, a bearing plate 101a is provided at the end of the weighing shell 101, a limiting post 101a-1 is provided on the end face of the bearing plate 101a, a fixing sleeve 101a-2 is sleeved on the outer wall of the limiting post 101a-1, a support plate 101b is provided on the outer wall of the weighing shell 101, a hinge block 101b-1 is provided on the outer wall of the support plate 101b, and a protective shell 101c is provided on the outer wall of the support plate 101b.

[0049] The bearing plate 101a is positioned above the weighing shell 101. Limiting posts 101a-1 are provided at the four corners of the lower surface of the bearing plate 101a. The limiting posts 101a-1 are located in the fixing sleeve 101a-2 on the bottom surface of the weighing shell 101 to limit the bearing plate 101a. Meanwhile, the fixing shell 103 is connected to the supporting plate 101b on the side of the weighing shell 101.

[0050] In summary, during use, the rubber pipe transports sample coal downward through the fixed shell 103. The falling sample coal is collected by the material box above the bearing plate 101a. When the sample coal in the material box accumulates to a certain weight, it drives the bearing plate 101a to move downward. The limiting post 101a-1 moves downward within the fixed sleeve 101a-2. The downward movement of the bearing plate 101a drives the pushing component 201 to move. The pushing component 201 drives the material box above the transport shell 102 to move onto the bearing plate 101a, thus pushing the material box on the bearing plate 101a.

[0051] At this time, as the bearing plate 101a presses down, the transmission component 202 inside the weighing shell 101 drives the moving component 203 inside the fixed shell 103 to provide power to the locking component 204. Furthermore, when the sample coal inside the material box bears a certain weight and presses down, the bearing plate 101a presses down onto the weighing shell 101, causing the locking component 204 to squeeze and lock the rubber pipe. At this time, the sample coal above cannot continue to fall.

[0052] At this point, the gap between the support plate 101a and the weighing shell 101 is closed. The new material box above the transport shell 102 can be pushed onto the support plate 101a. When the new material box is pushed onto the support plate 101a, it pushes the full material box, causing it to move towards the side conveyor belt. The height of the conveyor belt is slightly lower than the weighing shell 101. When the pusher 201 pushes the new material box onto the support plate 101a, the full material box is still located on the support plate 101a and continues to push the support plate 101a downwards. When the empty material box is completely above the support plate 101a, the full material box, due to being pushed, is slowly pushed from the support plate 101a towards the conveyor belt. The full material box is slowly shifted from the support plate 101a towards the conveyor belt. The material box, initially placed entirely on the support plate 101a, becomes partially suspended above the conveyor belt. When an empty material box replaces a full one, the full material box is less than halfway positioned on the support plate 101a. At this point, the full material box tilts, with one side pressing against the conveyor belt. Due to the friction of the conveyor belt, the full material box shifts from being pressed against the belt on one side to being completely embedded in the conveyor belt. The empty material box replaces the original position of the material box. At this point, the empty material box can no longer push the support plate 101a down, and the support plate 101a resets on the weighing shell 101. The pusher 201 returns to its original position and prepares to push the next empty material box. The upper locking element 204 also resets, and the sample coal continues to fall into the material box below.

[0053] Example 3

[0054] Reference Figures 3-6This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that when the pusher 201 moves toward the support plate 101a, it will drive the new material box to move above the support plate 101a. When resetting, it will move to the rear of the next material box through the L-shaped rod to prepare for the next operation.

[0055] Specifically, the transport shell 102 has a transport groove 102a on its end face, and the pusher 201 includes a pusher post 201a disposed at the end of the support plate 101a. The outer wall of the pusher post 201a is provided with a sliding post 201a-1, and the outer wall of the pusher post 201a is fitted with a pusher sleeve 201b. The outer wall of the pusher sleeve 201b is provided with a pusher groove 201b-1, and the end of the sliding post 201a-1 extends to the inner wall of the pusher groove 201b-1 and slides therewith.

[0056] The transport trough 102a is opened on both sides of the end face of the transport shell 102. The push column 201a is set below the support plate 101a. The push column 201a can be driven to move downward by the downward movement of the support plate 101a. A sliding column 201a-1 is provided on the outer side of the lower end of the push column 201a. The sliding column 201a-1 slides in the push groove 201b-1 opened on the outer wall of the push sleeve 201b. The downward movement of the push column 201a drives the rotation of the push sleeve 201b.

[0057] Preferably, a push plate 201c is provided on the outer wall of the push sleeve 201b, a connecting rod 201d is hinged to the end face of the push plate 201c, a push block 201e is hinged to the other end of the connecting rod 201d, an irregular groove 201e-1 is provided on the end face of the push block 201e, an L-shaped rod 201e-2 is hinged to the end face of the push block 201e, the end of the L-shaped rod 201e-2 extends to the inner wall of the transport groove 102a and slides therewith, and a limiting slide rail 201f is provided on the inner wall of the transport shell 102, the end of the limiting slide rail 201f extends to the inner wall of the irregular groove 201e-1 and slides therewith.

[0058] When the push sleeve 201b rotates, the push plate 201c on the outer wall of the push sleeve 201b rotates together. When the push plate 201c rotates, the connecting rod 201d on the upper surface of the push plate 201c drives the push block 201e to move. The push block 201e slides on the limiting slide rail 201f through the irregular groove 201e-1, so that the push block 201e can only move horizontally. The L-shaped rod 201e-2 above the push block 201e moves towards the bearing plate 101a. When the bottom rod of the L-shaped rod 201e-2 presses against the surface of the push block 201e, the L-shaped rod 201e-2 can move the object. When the L-shaped rod 201e-2 moves away from the bearing plate 101a, the upper rod of the L-shaped rod 201e-2 will flip when it touches the object, causing the L-shaped rod 201e-2 to retract into the transport trough 102a. When it passes under the object, the L-shaped rod 201e-2 returns to its original position due to the gravity of the bottom rod of the L-shaped rod 201e-2, and the upper rod extends out of the transport shell 102 again, which can push the material box.

[0059] In summary, during use, when the bearing plate 101a moves downward, it drives the push column 201a to move into the push sleeve 201b. Through the sliding column 201a-1, it drives the push sleeve 201b to rotate. Through the rotation of the push sleeve 201b, it drives the push plate 201c outside the push sleeve 201b to rotate. When the push plate 201c rotates, the connecting rod 201d on the push plate 201c drives the push block 201e to slide on the limit slide rail 201f. Through the L-shaped rod 201e-2 hinged above the push block 201e, it drives the material box to move.

[0060] Example 4

[0061] Reference Figures 4-8 This is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment, except that the rubber pipe is locked by the locking member 201 to prevent the sample coal above from falling further.

[0062] Specifically, the transmission component 202 includes a transmission column 202a disposed at the end of the bearing plate 101a. A first elastic element 202a-1 is disposed at the end of the transmission column 202a. A fixed sleeve 202b is sleeved on the outer wall of the transmission column 202a. A transmission ring 202c is fixedly sleeved on the outer wall of the transmission column 202a. A first hinge rod 202c-1 is hinged to the outer wall of the transmission ring 202c. A second hinge rod 202c-2 is hinged to the end of the first hinge rod 202c-1. A third hinge rod 202c-3 is hinged to the other end of the second hinge rod 202c-2. The outer wall of the third hinge rod 202c-3 is hinged to the hinge block 101b-1. A moving rod 202d is hinged to the end of the third hinge rod 202c-3.

[0063] The transmission column 202a is fixed below the bearing plate 101a and moves up and down within the fixed sleeve 202b. A first elastic element 202a-1 at the bottom of the transmission column 202a is located within the fixed sleeve 202b. When the bearing plate 101a moves downward, the transmission column 202a moves downward within the fixed sleeve 202b and presses against the first elastic element 202a-1. The transmission ring 202c on the outer wall of the transmission column 202a moves up and down together with the transmission column 202a. A first hinge rod 202c-1 is hinged to the outer wall of the transmission ring 202c, and a second hinge rod 202 is hinged to the bottom end of the first hinge rod 202c-1. c-2, one end of the third hinge rod 202c-3 and the end of the second hinge rod 202c-2 are hinged together. The middle position of the third hinge rod 202c-3 is hinged to the hinge block 101b-1. When the transmission ring 202a moves downward, the first hinge rod 202c-1 moves downward, driving the second hinge rod 202c-2 to move. Since the middle position of the third hinge rod 202c-3 is hinged to the hinge block 101b-1, when the second hinge block 202c-2 moves downward, it pushes the end of the third hinge rod 202c-3 to move outward, and the moving rod 202d hinged at the top of the third hinge rod 202c-3 moves inward.

[0064] Preferably, the moving part 203 includes a push rod 203a, the end of the push rod 203a is hinged to the moving rod 202d, the end of the push rod 203a is provided with a first push plate 203a-1 and a second push plate 203a-2, and the outer wall of the first push plate 203a-1 is provided with a limit block 203a-3.

[0065] Among them, the push rod 203a and the motion rod 202d are hinged together. The push rod 203a is driven forward by the motion rod 202d, which drives the first push plate 203a-1 and the second push plate 203a-2 at the end to move.

[0066] The moving part 203 also includes a first fixing plate 203b disposed inside the fixing shell 103. A fixing block 203b-1 is provided on the outer wall of the first fixing plate 203b. The end of the fixing block 203b-1 is hinged to the end of the second push plate 203a-2. A square plate 203c is connected to the outer wall of the first fixing plate 203b. A groove 203c-1 is provided on the outer wall of the square plate 203c.

[0067] Among them, the groove 203c-1 opened on the surface of the square plate 203c, the limiting block 203a-3 connected to the surface of the first push plate 203a-1 moves up and down in the groove 203c-1, the bottom end of the second push plate 203a-2 is hinged to the fixing block 203b-1 on the outer wall of the first fixing plate 203b, when the moving rod 202d drives the pushing rod 203a to move inward, the limiting block 203a-3 hinged to the bottom end of the first push plate 203a-1 moves from top to bottom in the groove 203c-1, driving the square plate 203c to move forward.

[0068] A movable rod 203d is provided on the outer wall of the square plate 203c. A second fixed plate 203d-1 is provided on the outer wall of the movable rod 203d. A second elastic element 203d-2 is sleeved on the outer wall of the movable rod 203d. A moving sleeve 203e is provided at the end of the movable rod 203d. A connecting post 203e-1 is provided on the outer wall of the moving sleeve 203e. A threaded rod 203f is provided on the inner wall of the moving sleeve 203e.

[0069] The movable rod 203d is connected to the square plate 203c. When the square plate 203c moves forward, the movable rod 203d moves together. The square plate 203c will squeeze the second elastic element 203d-2 sleeved on the outer wall of the movable rod 203d. Through the movement of the movable rod 203d, the moving sleeve 203e will move forward together. The connecting post 203e-1 on the surface of the moving sleeve 203e extends into the thread groove of the internal threaded rod 203f. Since the threaded rod 203f is fixed, it will not move back and forth. Therefore, when the moving sleeve 203e drives the connecting post 203e-1 to move back and forth on the threaded rod 203f, the connecting post 203e-1 will cause the threaded rod 203f to rotate.

[0070] The locking component 204 includes a moving ring 204a, an installation block 204a-1 at the end of the moving ring 204a, a second worm gear 204b on the inner wall of the installation block 204a-1, a moving groove 204a-2 on the end face of the moving ring 204a, a rotating arm of the second worm gear 204b connected to a threaded rod 203f, a second turbine 204c on the end face of the moving ring 204a, and the second turbine 204c meshing with the second worm gear 204b.

[0071] The rotating arm of the second worm 204b is connected to the threaded rod 203f. The rotation of the threaded rod 203f drives the second worm 204b to rotate, thereby causing the second turbine 204c to rotate. When the second turbine 204c rotates, it drives the moving groove 204a-2 on the surface to move.

[0072] Preferably, a slider 204d is provided in the moving groove 204a-2, a fixed ring 204e is provided on the end face of the moving ring 204a, a cross groove 204e-1 is provided on the outer wall of the fixed ring 204e, a cross slider 204f is provided on the end face of the slider 204d, the cross slider 204f slides in cooperation with the cross groove 204e-1, an auxiliary block 204f-1 is connected to the end of the cross slider 204f, and a locking block 204g is connected to the outer wall of the auxiliary block 204f-1.

[0073] In this design, the slider 204d inside the moving groove 204a-2 is connected to the bottom of the cross slider 204f. The cross slider 204f is located in the cross groove 204e-1 on the outer wall of the fixed ring 204e. When the moving ring 204a rotates, the fixed ring 204e does not move. Therefore, when the moving ring 204a rotates below the fixed ring 204e, the slider 204d inside the moving ring 204a moves in the moving groove 204a-2, causing the cross slider 204f to slide in the cross groove 204e-1 on the outer surface of the fixed ring 204a, which in turn causes the locking block 204g to move inward and lock the rubber tube in the middle.

[0074] In summary, during use, the downward pressure of the bearing plate 101a causes the transmission ring 202c to move downward along with the transmission column 202a. As the transmission ring 202c moves downward, the first hinge rod 202c-1, hinged to the outer wall of the transmission ring 202c, drives the second hinge rod 202c-2 to move downward together, causing the bottom of the third hinge rod 202c-3 to move outward. The middle position of the third hinge rod 202c-3 is hinged to the hinge block 101b-1, and the top of the third hinge rod 202c-3 is pushed inward, driving the moving rod 202d, causing the pushing rod 203a to move inward. The second push plate 203a of the pushing rod 203a... -2 and the fixed block 203b-1 are hinged. When the push rod 203a is pushed inward, the first push plate 203a-1 drives the limiting block 203a-3 to move in the groove 203c-1 on the surface of the square plate 203c, so that the square plate 203c moves forward, pushing the movable rod 203d forward, and causing the moving sleeve 203e set at the end of the movable rod 203d to move horizontally back and forth on the threaded rod 203f. The threaded rod 203f rotates through the connecting post 203e-1 set outside the moving sleeve 203e. The threaded rod 203f is connected to the rotating arm of the second worm 204b, driving the second worm 204b to rotate, thereby driving the second turbine 204c to rotate.

[0075] When the second turbine 204c rotates, it drives the moving ring 204a to rotate. The fixed ring 204e on the end face of the moving ring 204a remains stationary. When the moving ring 204a rotates, the slider 204d in the moving groove 204a-2 on the surface of the moving ring 204a drives the cross slider 204f to slide in the cross groove 204e-1 on the outer wall of the fixed ring 204e, which drives the locking block 204g at the upper end of the auxiliary block 204f-1 to move inward and lock the rubber pipe.
