Description

Technical Field

[0001] The present invention relates to the technical field of spray dust suppression, and particularly relates to a modular spray dust suppression system that is easy to install. Background Art

[0002] During the loading, unloading and conveying of bulk materials such as coal, dust pollution is a core problem that has long troubled industrial production. Dust will pollute the surrounding environment, affect the respiratory health of operating personnel and even cause explosion accidents. Therefore, dust suppression during conveying is required. Currently, a bulk loader is usually used as the key equipment for dust suppression and conveying of materials. The telescopic discharge pipe and telescopic cover inside the bulk loader are used in cooperation to convey the materials from a high position to a storage bin, and dust removal is carried out by means of lateral dust suction.

[0003] Among them, the discharge pipes on the bulk loader are connected by a plurality of baffles. The baffles are welded to the discharge pipes to achieve the limit and anti-disengagement of the discharge pipes. When the discharge pipe needs to be replaced due to wear, the baffle needs to be cut first before the corresponding discharge pipe can be replaced. And during the cutting process, the adjacent discharge pipes will be damaged. After replacing the new discharge pipe, welding operations for a plurality of baffles are required again, and the overall process is cumbersome. In addition, the telescopic covers on the bulk loader mostly adopt an integral corrugated pipe structure. When a part of the telescopic cover is damaged due to wear or other reasons, the entire telescopic cover needs to be replaced, thus increasing the maintenance and conveying costs.

[0004] Therefore, solving the problems in the existing design of the bulk loader, such as the discharge pipes limited by welded baffles and the integral corrugated pipe telescopic cover structure, which lead to difficult component replacement, cumbersome maintenance process and high costs, is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above problems, embodiments of the present invention provide a modular spray dust suppression system that is easy to install to solve the above-mentioned technical problems.

[0006] To achieve the above object, embodiments of the present invention provide the following technical solution: A modular spray dust suppression system that is easy to install, including an equipment frame, a bottom plate installed thereon, a feeding mechanism and a limiting shaft.

[0007] The feeding mechanism includes a plurality of discharge pipes that are sleeved one by one from bottom to top and arranged at the lower end of the bottom plate. A bulk head is provided at the lower end of the lowermost discharge pipe; a plurality of inclined support rods are circumferentially arranged between adjacent two discharge pipes. The lower end of the support rod is movably connected to the corresponding discharge pipe, and a limiting block is hinged to the upper end; after two discharge pipes are sleeved up and down, the lower discharge pipe is rotated to limit the up and down movement of the limiting block; the limiting shaft is arranged between the discharge pipes at the head and tail, and prevents the sleeved discharge pipes from rotating by passing through and inserting into the discharge pipes.

[0008] A steel wire rope for pulling the bulk head to lift is arranged on the bottom plate. When the bulk head moves downward, all the discharge pipes except the uppermost discharge pipe move vertically downward, so that the material conveying channel is extended. At the same time, the inclination angle of the support rod increases and supports the upper discharge pipe.

[0009] A plurality of telescopic covers are arranged between the lower end of the bottom plate and the bulk head. Adjacent two telescopic covers are detachably connected with the corresponding discharge pipes through connecting rings, and the telescopic covers expand and contract as the discharge pipes move; A dust suction pipe communicated with the material conveying channel is arranged on the bottom plate, and a spray head for spraying dust suppression is arranged on the bulk head.

[0010] As a preferred scheme, a connecting piece for supporting and restricting the movement of the support rod is arranged on the discharge pipe. The connecting piece includes a support ring. Support rings are fixedly installed at the upper and lower ends of the outer walls of all the discharge pipes except the lowermost discharge pipe. Guide shafts evenly distributed in the circumferential direction are fixedly installed along the same axis between the two support rings on the same discharge pipe. A slider is slidably installed on the guide shaft along its axial direction. The lower end of the support rod is hinged with the slider, and a limiting piece for restricting the movement of the upper end of the support rod is arranged on the discharge pipe.

[0011] As a preferred scheme, the material conveying mechanism further includes a through hole opened on the bottom plate and coaxial with the discharge pipe. A hopper and a connecting pipe coaxial with the through hole are respectively fixedly installed at the upper and lower ends of the bottom plate. The lower end of the connecting pipe is detachably connected with the uppermost discharge pipe, and the bulk head is detachably connected with the lowermost discharge pipe.

[0012] As a preferred scheme, a guiding piece for guiding the movement of the steel wire rope is arranged on the bottom plate. The guiding piece includes a guiding wheel. Two guiding wheels distributed up and down are rotatably installed on the upper end of the bottom plate and on the front and rear sides of the hopper through a support plate. An equipment box for winding and unwinding the steel wire rope is arranged on the upper end of the bottom plate and on the left side of the hopper. The number of steel wire ropes is two and they are respectively fixed at the front and rear ends of the bulk head. The upper ends of the steel wire ropes pass through the bottom plate movably and then pass through between the corresponding two guiding wheels, and finally are connected with the equipment box.

[0013] As a preferred scheme, the discharge pipe has a frustum-shaped structure with a larger diameter at the upper end than at the lower end. A flange is arranged at the upper end of the discharge pipe. A plurality of circumferentially distributed limiting shafts are installed at the upper end of the lowermost flange and the lower end of the uppermost flange, and the limiting shafts on the two flanges are staggered. One end of the limiting shaft slidably passes through all the flanges except the flange to which it is connected and installed.

[0014] As a preferred scheme, fixing rings are coaxially and fixedly installed on the outer rings of all the flanges except the uppermost flange through struts. The connecting ring is assembled by two semi-circular rings through ear seats and bolts. The steel wire rope movably passes through between the ear seats on the same side of the connecting ring. Positioning columns are evenly and fixedly installed on the inner wall of the inner ring of the connecting ring along its circumferential direction, and the positioning columns sequentially slide through the telescopic cover and the fixing ring.

[0015] As a preferred solution, a spraying member for spraying and suppressing dust in communication with the spray head is provided on the bulk head. The spraying member includes two liquid storage shells coaxially and fixedly arranged on the outer wall of the bulk head from top to bottom. The outer ring wall of the lower liquid storage shell is uniformly communicated with spray heads along its circumferential direction, and the axis of the lower spray head extends along the radial direction of the liquid storage shell. The lower end of the upper liquid storage shell is also uniformly and obliquely communicated with spray heads along its circumferential direction, and the upper spray heads are arranged obliquely downward. The upper spray heads and the lower spray heads are arranged in a staggered manner.

[0016] As a preferred solution, a fixed pipe located outside the connecting pipe is fixedly installed at the lower end of the bottom plate. The dust suction pipe fixedly penetrates the bottom plate and is communicated with the fixed pipe. The uppermost telescopic cover is coaxially and detachably installed at the lower end of the fixed pipe, and the lowermost telescopic cover is detachably connected to the bulk head. A plurality of dust blocking plates are uniformly installed along the circumferential direction at the lower end of the bulk head.

[0017] As a preferred solution, the limiting member includes a clamping groove. The clamping groove is opened at the upper end of the discharge pipe and corresponds to the guide shafts one by one. The limiting blocks are slidably installed in the corresponding clamping grooves.

[0018] As a preferred solution, the clamping groove penetrates the inner ring wall of the discharge pipe, and the horizontal cross-section of the clamping groove is in an L-shaped structure. The upper end of the vertical section of the clamping groove penetrates the upper end of the discharge pipe.

[0019] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the plurality of discharge pipes provided in the present invention can be connected and assembled through limiting blocks and support rods. The positions of the discharge pipes are restricted by the limiting shafts, realizing the rapid assembly of the discharge pipes, forming a stable material conveying channel, thereby improving the assembly efficiency of the discharge pipes and reducing the subsequent maintenance cost. At the same time, the outer side of the material conveying channel is protected by multiple independent telescopic covers, and each telescopic cover can be disassembled and replaced, thus reducing the maintenance cost of the telescopic covers.

[0020] Second, after the discharge pipes are sleeved on each other up and down, the limiting blocks are restricted to move up and down by rotating the lower discharge pipe. At the same time, the rotation of the discharge pipes is restricted by the way that the limiting shafts penetrate the discharge pipes, forming a material conveying channel with variable length and without the need for overall disassembly and replacement; when it is necessary to disassemble and replace the corresponding discharge pipe, it can be disassembled without damaging the adjacent discharge pipes, and the disassembly and assembly operations of the discharge pipes are simple and fast.

[0021] Third, the present invention connects two adjacent telescopic covers through the cooperation of the connecting ring and the positioning column, thereby forming an outer side telescopic protective layer composed of multiple independent segments. Each telescopic cover can be disassembled separately. When a certain telescopic cover is damaged, only the corresponding connecting ring needs to be loosened to replace the telescopic cover, without the need for overall replacement, which is convenient for the disassembly, replacement and installation of the telescopic cover and also reduces the maintenance cost.

[0022] IV. The present invention adsorbs the dust in the telescopic cover through a dust suction pipe, and suppresses the dust outside the outer telescopic protective layer in real time through a spray head. Under the dust removal method combining upward suction and downward spraying, the dust suppression effect during the operation of the bulk loader is improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] As Figure 1 shown, a modular spray dust suppression system that is easy to install includes an equipment rack 10, and a bottom plate 11 is installed on the equipment rack 10, and a feeding mechanism 2 is provided on the bottom plate 11.

[0034] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the feeding mechanism 2 includes a plurality of discharge pipes 20 sleeved one by one from bottom to top. The uppermost discharge pipe 20 is arranged at the lower end of the bottom plate 11, and a bulk head 21 is arranged at the lower end of the lowermost discharge pipe 20; a plurality of inclined support rods 53 are arranged circumferentially between two adjacent discharge pipes 20, and the lower end of the support rod 53 is movably installed on the discharge pipe 20 close to the bottom plate 11.

[0035] As Figure 1 , Figure 2 , Figure 4 and Figure 6 shown, a steel wire rope 260 for pulling the bulk head 21 to move up and down is arranged on the bottom plate 11. When the bulk head 21 moves downward, all the discharge pipes 20 except the uppermost one move downward, so that the feeding channel is extended. At the same time, the lower end of the support rod 53 moves downward along the discharge pipe 20 to which it is movably connected, and the inclination angle of the support rod 53 increases and supports the discharge pipe 20. A limiting shaft 22 is arranged between the discharge pipes 20 at both ends, and the limiting shaft 22 prevents the sleeved discharge pipes 20 from rotating by passing through and inserting into the discharge pipes 20.

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a plurality of telescopic covers 31 are arranged between the lower end of the bottom plate 11 and the bulk head 21. Each of the discharge pipes 20 except the two at both ends corresponds to a telescopic cover 31. Two adjacent telescopic covers 31 are connected by a connecting ring 25, and the connecting ring 25 is detachably connected to the corresponding discharge pipe 20. The telescopic cover 31 expands and contracts as the discharge pipe 20 moves; a dust suction pipe 32 is also arranged on the bottom plate 11, and a spray head 41 for dust suppression is arranged on the bulk head 21.

[0037] During specific operation, the discharge pipes 20 are installed one by one from bottom to top, and the discharge pipes 20 are rotated to restrict the movement of the upper end of the support rod 53. After the installation of the discharge pipes 20 is completed, the limiting shafts 22 penetrate through the corresponding discharge pipes 20 to restrict the rotation of the discharge pipes 20. Then, the bulk head 21 is installed on the lowermost discharge pipe 20. Next, the telescopic covers 31 are installed one by one from top to bottom, and the connecting rings 25 are connected to the corresponding discharge pipes 20 to fix the telescopic covers 31. Finally, the lowermost telescopic cover 31 is connected to the bulk head 21.

[0038] When the material conveying channel needs to be extended, the steel wire rope 260 is lowered, and the bulk head 21 moves downward under its own gravity, driving the discharge pipes 20 to move downward. The total length of all the discharge pipes 20 in the up-and-down direction increases, thereby extending the material conveying channel. Then, the material passes through each discharge pipe 20 in sequence from the uppermost discharge pipe 20 and drops from the lowermost discharge pipe 20 into the storage bin. During the material conveying process, the dust is sucked out through the dust suction pipe 32, and the dust scattered outside the bulk head 21 after the material falls is suppressed from spreading by the water mist sprayed by the spray head 41.

[0039] As Figure 1 、 Figure 2 and Figure 4 As shown in

[0040] As Figure 2 and Figure 4 shown, the discharge pipe 20 has a frustum-shaped structure with a larger diameter at the upper end than at the lower end. A flange is provided at the upper end of the discharge pipe 20. A plurality of circumferentially distributed limiting shafts 22 are installed at the upper end of the lowermost flange and the lower end of the uppermost flange, and the limiting shafts 22 on these two flanges are staggeredly distributed. One end of the limiting shaft 22 slidably penetrates through all the flanges except the flange to which it is connected and installed.

[0041] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, a connecting member 5 for supporting and restricting the movement of the support rod 53 is provided on the discharge pipe 20. The connecting member 5 includes a support ring 50. Support rings 50 are fixedly installed at both the upper and lower ends of the outer walls of all discharge pipes 20 except the lowermost discharge pipe 20. Circumferentially uniformly distributed guide shafts 51 are fixedly installed between two support rings 50 on the same discharge pipe 20. A slider 52 is slidably installed on the guide shaft 51 along its axial direction. The lower end of the support rod 53 is hinged to the slider 52. A limiting member 54 for restricting the movement of the upper end of the support rod 53 is provided on the discharge pipe 20.

[0042] As Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the limiting member 54 includes a limiting block 541 and a card slot 540. The card slot 540 is opened at the upper end of the flange of the discharge pipe 20 and corresponds to the guide shaft 51 one by one. A limiting block 541 is slidably installed in the card slot 540. The upper end of the support rod 53 is hinged to the corresponding limiting block 541. The card slot 540 penetrates the inner ring wall of the discharge pipe 20, and the horizontal cross-section of the card slot 540 is in an L-shaped structure. The vertical section of the card slot 540 penetrates the upper end of the discharge pipe 20.

[0043] During specific operation, first fix the uppermost discharge pipe 20 at the lower end of the connecting pipe 24, and then install the remaining discharge pipes 20 one by one. During this process, while the next discharge pipe 20 is sleeved on the previous discharge pipe 20, the limiting block 541 is inserted into the vertical section of the card slot 540, and then the lower discharge pipe 20 is rotated to move the limiting block 541 into the horizontal section of the card slot 540 to restrict the up and down movement of the limiting block 541. Before installing the lowermost discharge pipe 20, first pass the limiting shaft 22 corresponding to the uppermost flange through the corresponding flange from bottom to top and then fix it to the uppermost flange (for example, fixed by structures such as bolts), and then pass the limiting shaft 22 corresponding to the lowermost flange through the corresponding discharge pipe 20 first, and then install the lowermost discharge pipe 20. After the lowermost discharge pipe 20 is installed, fix the lowermost flange to the corresponding limiting shaft 22 (for example, fixed by structures such as bolts).

[0044] During the process that the bulk head 21 moves downward and drives the discharge pipe 20 to move downward to extend the material conveying channel, the slider 52 will move downward along the corresponding guide shaft 51. Since the guide shaft 51 is in an inclined state and the limit block 541 moves vertically downward along with the discharge pipe 20, during the downward movement of the discharge pipe 20, the horizontal distance between the limit block 541 and the guide shaft 51 gradually increases. At this time, the support rod 53 will rotate, and its inclination angle increases, that is, the included angle between the support rod 53 and the corresponding guide shaft 51 increases. When the bulk head 21 moves upward and drives the discharge pipe 20 to move upward, the slider 52 moves upward along the corresponding guide shaft 51, the horizontal distance between the limit block 541 and the guide shaft 51 gradually decreases, and at the same time, the support rod 53 rotates back to its original position. To sum up, during the movement of the discharge pipe 20, the support rod 53 always supports the lower end of the corresponding discharge pipe 20, thereby ensuring the stability of the discharge pipe 20 during the material conveying process, and further ensuring the stability of the material conveying channel.

[0045] As Figure 1 and Figure 2 shown, a fixed pipe 30 located outside the connecting pipe 24 is fixedly installed at the lower end of the bottom plate 11. The dust suction pipe 32 fixedly penetrates through the bottom plate 11 and is communicated with the fixed pipe 30. The uppermost telescopic cover 31 is coaxially and detachably installed at the lower end of the fixed pipe 30, and the lowermost telescopic cover 31 is detachably connected to the bulk head 21. A plurality of dust baffle plates 33 are uniformly installed along the circumference at the lower end of the bulk head 21.

[0046] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, fixed rings 542 are coaxially and fixedly installed on the outer rings of all flanges except the uppermost flange through columns. The connecting ring 25 is assembled by two semi-circular rings through ear seats and bolts. Positioning columns 543 are uniformly fixedly installed on the inner wall of the inner ring of the connecting ring 25 along the circumference, and the positioning columns 543 sequentially slide through the telescopic cover 31 and the fixed ring 542.

[0047] During specific operation, first fix the uppermost telescopic cover 31 to the fixed pipe 30, then install the remaining telescopic covers 31 one by one, and make the positioning columns 543 on the connecting ring 25 penetrate through the corresponding two telescopic covers 31 and the corresponding fixed rings 542, so as to connect and lock two adjacent telescopic covers 31, and then connect and fix the lowermost telescopic cover 31 to the bulk head 21. During the material conveying process, dust will disperse in the telescopic cover 31. At this time, it is communicated with the dust suction pipe 32 through an external suction pump to suck out the dust in the telescopic cover 31 for centralized collection and treatment.

[0048] In addition, through the connection between the positioning posts 543 and the fixing ring 542, the telescopic cover 31 synchronously and stably expands and contracts along with the movement of the discharge pipe 20. During the process of the discharge pipe 20 moving to extend the material conveying channel, the displacement amounts of the respective discharge pipes 20 will be different, which will in turn cause the expansion and contraction frequencies and amounts of the respective telescopic covers 31 to be different, and the respective telescopic covers 31 will be damaged to varying degrees. However, the multiple telescopic covers 31 in the present invention are combined and spliced, which facilitates the replacement of a single telescopic cover 31 without the need for overall replacement, reducing the maintenance cost.

[0049] As Figure 1 and Figure 4 shown, a guiding member 26 for guiding the movement of the steel wire rope 260 is provided on the bottom plate 11. The guiding member 26 includes a guiding wheel 261. Two guiding wheels 261 distributed up and down are rotatably installed on the upper end of the bottom plate 11 on the front and rear sides of the hopper 23 through support plates. A device box 262 for winding and unwinding the steel wire rope 260 is provided on the upper end of the bottom plate 11 on the left side of the hopper 23. The device box 262 is a prior art and mainly includes a stepping motor and a winding wheel installed on the output shaft of the stepping motor for winding and unwinding the steel wire rope 260. The number of the steel wire ropes 260 is two and they are respectively fixed at the front and rear ends of the bulk head 21. The upper ends of the steel wire ropes 260 movably penetrate through the bottom plate 11 and then pass between the corresponding two guiding wheels 261, and finally are wound around the corresponding winding wheels, and the steel wire ropes 260 movably penetrate through the corresponding ear seats on the connecting ring 25.

[0050] As Figure 1 、 Figure 2 and Figure 4 shown, a spraying member 4 for spraying and suppressing dust in communication with the spray head 41 is provided on the bulk head 21. The spraying member 4 includes two liquid storage shells 40 coaxially fixed on the outer wall of the bulk head 21 from top to bottom. The outer ring wall of the lower liquid storage shell 40 is uniformly communicated with spray heads 41 along its circumferential direction, and the axes of the lower spray heads 41 extend along the radial direction of the liquid storage shell 40. The lower end of the upper liquid storage shell 40 is also uniformly communicated with spray heads 41 along its circumferential direction, and the upper spray heads 41 are arranged obliquely downward. The upper spray heads 41 and the lower spray heads 41 are arranged in a staggered manner.

[0051] During specific operation, the stepping motor releases the steel wire rope 260 through the winding wheel, and the bulk head 21 moves downward under its own gravity. At the same time, the bulk head 21 drives the discharge pipe 20 to move downward to extend the material conveying channel. Then, before material conveying, an external water pump is communicated with the liquid storage shell 40 through a water delivery pipe. As the water pressure in the liquid storage shell 40 increases, water is sprayed out in a mist shape through the spray heads 41, and the water mist is used to suppress dust during the material conveying process. The upper spray heads 41 and the lower spray heads 41 are arranged in a staggered manner to supplement the spraying range of the lower spray heads 41 by the upper spray heads 41, realizing comprehensive spraying, so as to ensure the effect of spray dust suppression.

[0052] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself. In addition, in the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0053] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
