Description

Technical Field

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

[0002] During the loading, unloading and transportation of bulk materials such as coal, dust pollution is a core problem that has long plagued industrial production. Dust will pollute the surrounding environment, affect the respiratory health of workers and even cause explosion accidents, so dust suppression and transportation are required. At present, bulk loaders are usually used as key equipment for dust suppression and transportation of materials. The materials are transported from a high position to the storage bin through the retractable discharge pipe and telescopic cover inside the bulk loader, and dust is removed by lateral dust suction.

[0003] Among them, the discharge pipes on the bulk loader are connected by multiple baffles, and the baffles are welded to the discharge pipes to achieve the limit and anti-detachment of the discharge pipes. When the discharge pipe needs to be replaced due to wear, the baffles need to be cut before the corresponding discharge pipe can be replaced, and the cutting will damage the adjacent discharge pipes. After replacing the new discharge pipe, multiple baffles need to be welded, and the overall process is cumbersome. In addition, the telescopic cover on the bulk loader mostly adopts an integrated bellows structure. When a part of the telescopic cover is damaged due to wear and other reasons, the entire telescopic cover needs to be replaced, which increases the maintenance and transportation costs.

[0004] Therefore, it is a technical problem that technicians in this field need to solve to solve the problem that the discharge pipe with welded baffle limit and the one-piece bellows telescopic cover structure in the existing design of bulk loader make the replacement of parts difficult, the maintenance process complicated and the cost high.

An equipment box for retracting and releasing the wire rope is provided on the upper end of the bottom plate and located on the left side of the hopper. There are two wire ropes and they are respectively fixed at the front and rear ends of the bulk head. The upper end of the wire rope movably penetrates the bottom plate and passes between the corresponding two guide wheels, and is finally connected to the equipment box.

[0013] As a preferred embodiment, the discharge pipe is a truncated cone-shaped structure with a diameter at the upper end being larger than that at the lower end. A flange is provided at the upper end of the discharge pipe. A plurality of circumferentially distributed limit shafts are installed at the upper end of the lowermost flange and the lower end of the uppermost flange. The limit shafts on the two flanges are staggered, and one end of the limit shaft slides through all flanges except the flange to which it is connected and installed.

[0014] As a preferred solution, the outer rings of all flanges except the top flange are coaxially fixed with fixing rings through pillars, the connecting ring is composed of two semicircular rings assembled by ears and bolts, the wire rope movably passes through the ears on the same side of the connecting ring, and the inner ring wall of the connecting ring is evenly fixed with positioning columns along its circumference, and the positioning columns slide in turn through the telescopic cover and the fixing ring.

[0020] 2. After the discharge pipes are connected to each other up and down, the present invention limits the upward and downward movement of the limit block by rotating the lower discharge pipe, and at the same time limits the rotation of the discharge pipe by cooperating with the limit shaft to penetrate the discharge pipe, thereby forming a feed channel with variable length that does not require overall disassembly and replacement; when the corresponding discharge pipe needs to be disassembled and replaced, it can be disassembled without damaging the adjacent discharge pipes, and the disassembly and assembly operation of the discharge pipe is simple and quick.

[0021] 3. The present invention connects two adjacent telescopic covers by the cooperation of a connecting ring and a positioning column, thereby forming an outer telescopic protective layer composed of multiple independent sections. Each telescopic cover can be disassembled separately. When a telescopic cover is damaged, it is only necessary to loosen the corresponding connecting ring to replace the telescopic cover without replacing the entire cover. This facilitates the disassembly, replacement and installation of the telescopic cover while reducing maintenance costs.

[0022] Fourth, the present invention absorbs the dust in the telescopic cover through the dust suction pipe, and suppresses the dust outside the outer telescopic protective layer in real time by spraying through the spray head. Under the dust removal mode combining upper suction and lower spraying, the dust suppression effect of the bulk loader during operation is improved.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth 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 violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

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

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the feeding mechanism 2 includes a plurality of discharge pipes 20 which are sleeved one by one from bottom to top, the top discharge pipe 20 is arranged at the lower end of the base plate 11, and a bulk head 21 is arranged at the lower end of the bottom discharge pipe 20; a plurality of inclined support rods 53 are arranged between two adjacent discharge pipes 20 and along the circumferential direction, and the lower ends of the support rods 53 are movably mounted on the discharge pipe 20 close to the base plate 11.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a steel wire rope 260 for pulling the bulk head 21 up and down is provided on the bottom plate 11. When the bulk head 21 moves downward, all the discharge pipes 20 except the uppermost discharge pipe 20 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 movably connected thereto and the inclination angle of the support rod 53 increases to support the discharge pipe 20. A limiting shaft 22 is provided between the discharge pipes 20 at the head and tail ends. The limiting shaft 22 prevents the discharge pipe 20 from rotating after being connected by penetrating the discharge pipe 20.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a plurality of telescopic covers 31 are arranged between the lower end of the base plate 11 and the bulk head 21. All discharge pipes 20 except the first and last discharge pipes 20 correspond to a telescopic cover 31 respectively. Two adjacent telescopic covers 31 are connected by a connecting ring 25. The connecting ring 25 is detachably connected to the corresponding discharge pipe 20, and the telescopic cover 31 is extended and retracted as the discharge pipe 20 moves. A dust suction pipe 32 is also arranged on the base plate 11, and a spray head 41 for dust suppression is arranged on the bulk head 21.

[0037] During the specific work, the discharge pipes 20 are installed one by one from bottom to top, and the discharge pipes 20 are rotated to limit the movement of the upper end of the support rod 53. After the discharge pipes 20 are installed, the corresponding discharge pipes 20 are penetrated by the limit shaft 22 to limit the rotation of the discharge pipes 20. Then, the bulk head 21 is installed on the lowest discharge pipe 20, and then the telescopic covers 31 are installed one by one from top to bottom, and the connecting ring 25 is connected to the corresponding discharge pipe 20 to fix the telescopic cover 31. Finally, the lowest telescopic cover 31 is connected to the bulk head 21.

[0038] When it is necessary to extend the conveying channel, the wire rope 260 is lowered, and the bulk head 21 moves downward by its own gravity, and drives the discharge pipe 20 to move downward. The total length of all the discharge pipes 20 in the up and down directions increases, thereby extending the conveying channel. Then, the material passes through each discharge pipe 20 in turn from the top discharge pipe 20 and falls into the storage bin from the bottom discharge pipe 20. During the conveying process, the dust is sucked away by the dust suction pipe 32, and the dust floating outside the bulk head 21 after the material falls is suppressed from spreading by the water mist sprayed from the spray head 41.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, the feeding mechanism 2 also includes a through hole opened on the bottom plate 11 and coaxial with the discharge pipe 20, and a hopper 23 and a connecting pipe 24 coaxial with the through hole are fixedly installed at the upper and lower ends of the bottom plate 11 respectively, and the lower end of the connecting pipe 24 is fixedly connected to the uppermost discharge pipe 20 by bolts, and the bulk head 21 is fixedly connected to the lowermost discharge pipe 20 by bolts.

[0040] like Figure 2 and Figure 4 As shown, the discharge pipe 20 is a truncated cone-shaped structure with a diameter at the upper end being larger than that at the lower end. A flange is provided at the upper end of the discharge pipe 20, and a plurality of circumferentially distributed limit shafts 22 are installed at the upper end of the lowermost flange and the lower end of the uppermost flange, and the limit shafts 22 on the two flanges are staggered, and one end of the limit shaft 22 slides through all flanges except the flange connected and installed by itself.

[0041] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the discharge pipe 20 is provided with a connecting member 5 for supporting and limiting the movement of the support rod 53, and the connecting member 5 includes a support ring 50. The upper and lower ends of the outer walls of all the discharge pipes 20 except the lowest discharge pipe 20 are fixedly installed with support rings 50, and a circumferentially uniformly distributed guide shaft 51 is fixedly installed between the 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, and the lower end of the support rod 53 is hinged to the slider 52. The discharge pipe 20 is provided with a limiter 54 for limiting the movement of the upper end of the support rod 53.

[0042] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the limit member 54 includes a limit block 541 and a slot 540. The 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. The limit block 541 is slidably installed in the slot 540, and the upper end of the support rod 53 is hinged to the corresponding limit block 541; the slot 540 passes through the inner ring wall of the discharge pipe 20, and the horizontal cross-section of the slot 540 is an L-shaped structure, and the vertical section of the slot 540 passes through the upper end of the discharge pipe 20.

[0043] During the specific operation, the top discharge pipe 20 is first fixed to the lower end of the connecting pipe 24, and then the remaining discharge pipes 20 are installed one by one. During this process, the next discharge pipe 20 is sleeved on the previous discharge pipe 20, and the limit block 541 is inserted into the vertical section of the slot 540. Then the lower discharge pipe 20 is rotated to move the limit block 541 to the horizontal section of the slot 540 to limit the up and down movement of the limit block 541; before installing the lower discharge pipe 20, the limit shaft 22 corresponding to the uppermost flange is first passed through the corresponding flange from bottom to top and then fixedly connected with the uppermost flange (for example, fixed by bolts or other structures), and then the limit shaft 22 corresponding to the lowermost flange is first passed through the corresponding discharge pipe 20, and then the lowermost discharge pipe 20 is installed. After the installation of the lowermost discharge pipe 20 is completed, the lowermost flange is fixedly connected to the corresponding limit shaft 22 (for example, fixed by bolts or other structures).

[0044] In the process of the bulk head 21 moving downward and driving the discharge pipe 20 to move downward to extend the feeding channel, the slider 52 will move downward along the corresponding guide shaft 51. Because the guide shaft 51 is in an inclined state, and the limit block 541 moves vertically downward 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 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, and the horizontal distance between the limit block 541 and the guide shaft 51 gradually decreases, and the support rod 53 rotates and resets. In summary, during the movement of the discharge pipe 20, the support rod 53 always maintains support for the lower end of the corresponding discharge pipe 20, thereby ensuring the stability of the discharge pipe 20 during the feeding process, and further ensuring the stability of the feeding channel.

[0045] like Figure 1 and Figure 2 As shown, a fixed tube 30 located on the outer circle of the connecting tube 24 is fixedly installed at the lower end of the base plate 11, and a dust suction tube 32 is fixedly passed through the base plate 11 and connected with the fixed tube 30. The uppermost telescopic cover 31 is coaxially and detachably installed at the lower end of the fixed tube 30, and the lowermost telescopic cover 31 is detachably connected to the bulk head 21, and a plurality of dust shield plates 33 are evenly installed along the circumference of the lower end of the bulk head 21.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer rings of all flanges except the top flange are coaxially fixed with a fixing ring 542 through a support, the connecting ring 25 is assembled from two semicircular rings through ear seats and bolts, and the inner ring wall of the connecting ring 25 is evenly fixed with positioning columns 543 along its circumference, and the positioning columns 543 slide through the telescopic cover 31 and the fixing ring 542 in sequence.

[0047] In specific operation, the top telescopic cover 31 is first fixed to the fixed pipe 30, and then the remaining telescopic covers 31 are installed one by one, and the positioning column 543 on the connecting ring 25 passes through the corresponding two telescopic covers 31 and the corresponding fixed ring 542, so as to connect and lock the two adjacent telescopic covers 31, and then the bottom telescopic cover 31 is connected and fixed to the bulk head 21. During the feeding process, dust will float in the telescopic cover 31. At this time, the dust in the telescopic cover 31 is sucked out by connecting the external suction pump with the dust suction pipe 32 for centralized collection and treatment.

[0048] In addition, through the connection between the positioning column 543 and the fixing ring 542, the telescopic cover 31 can be synchronously and stably extended and retracted with the movement of the discharge pipe 20. In the process of the discharge pipe 20 moving to extend the feeding channel, the displacement of each discharge pipe 20 will be different, which will then make the telescopic frequency and telescopic amount of each telescopic cover 31 different, and each telescopic cover 31 will be damaged to different degrees. The combined splicing method of multiple telescopic covers 31 adopted by the present invention can facilitate the replacement of a single telescopic cover 31 without the need for overall replacement, thereby reducing maintenance costs.

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

[0050] like Figure 1 , Figure 2 and Figure 4 As shown, the bulk head 21 is provided with a spray component 4 which is connected with a spray head 41 for spraying and dust suppression. The spray component 4 includes two liquid storage shells 40 which are 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 evenly connected with the spray head 41 along its circumference, and the axis of the lower spray head 41 extends radially along the liquid storage shell 40. The lower end of the upper liquid storage shell 40 is also evenly connected with the spray head 41 along its circumference, and the upper spray head 41 is tilted downward, and the upper spray head 41 and the lower spray head 41 are staggered.

[0051] During specific operation, the stepper motor releases the wire rope 260 through the winding wheel, and the bulk head 21 moves downward by its own gravity. At the same time, the bulk head 21 drives the discharge pipe 20 to move downward to extend the feeding channel. Then, before feeding, the external water pump is connected to the liquid storage shell 40 through the water pipe. As the water pressure in the liquid storage shell 40 increases, water is sprayed out in a mist form through the spray head 41, and dust is suppressed during the material transportation. The upper spray head 41 and the lower spray head 41 are staggered so that the upper spray head 41 can supplement the spray range of the lower spray head 41 to achieve comprehensive spraying, thereby ensuring the effect of spraying dust suppression.

[0052] In the description of the present invention, it is necessary to understand that the orientation or positional relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, vertical, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. In addition, in the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0053] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "install", and "connect" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
