Description

Technical Field

[0001] The invention relates to a flap valve, and more particularly to a water slag flap valve. Background Art

[0002] Slag refers to the slag from an iron-making blast furnace. It is in a high-temperature molten state and is rapidly cooled with water to form a granulated foam shape. It is a soft material for foamed silicate building products, slag sound-absorbing bricks, insulation layers, and water-absorbing layers. The processed slag is usually accumulated at the valve, and the valve is opened to transfer it after the temperature drops to room temperature and it dries. High temperature can affect the accuracy of the valve, and granulated foam can easily clog the gap. Currently, flap valves without precise structures are often used as valves on the market. However, since the slag is in a high-temperature and humid state when it accumulates at the valve, a part of it is easily left attached to the inner wall of the valve after drying and cooling.

[0003] In view of the above reasons, how to clean the water residue attached to the inner wall of the valve is exactly the problem considered in this application. Summary of the invention

[0004] In view of the shortcomings of the prior art, a water slag flap valve is provided, which can clean the water slag attached to the inner wall of the valve.

[0005] To achieve the above-mentioned purpose, the following technical scheme is provided: a water slag flap valve, comprising a frame, a valve body and a cleaning mechanism arranged above the valve body and movable thereon are mounted on the frame, a valve is mounted at the bottom of the valve body, a foldable connecting channel is mounted on the top of the valve body, the connecting channel is used to connect the top of the frame and the valve body, the cleaning mechanism comprises a bracket, a first motor and an air pump connected to the first motor are connected to the outside of the bracket, the first motor is connected to a reciprocating mechanism, the reciprocating mechanism is connected to a scraper for scraping water slag, a blowing channel for blowing air downwards is arranged inside the scraper, and the blowing channel is connected to the blowing pump;

[0006] When cleaning, the cleaning agency performs the following operations:

[0007] Fold the connecting channel;

[0008] Move the cleaning mechanism to the top of the valve body and align the scraper with the inner wall of the valve body;

[0009] The first motor is started, and the reciprocating mechanism drives the scraper to perform reciprocating motion in the vertical direction.

[0010] In summary, the above technical solution has the following beneficial effects: when the valve is closed, the connecting channel is connected to the top of the frame to form a channel from the top of the frame to the inside of the valve body. At this time, the valve body and the valve in the closed state can temporarily store water slag. The accumulated water slag will leave the valve under the action of gravity after the valve is opened. However, since the water slag is in a high temperature and humid state when it accumulates in the valve body, it is easy to leave a part of the water slag attached to the inner wall of the valve after drying and cooling, so a cleaning mechanism is required to clean up these attachments;

[0011] The scraper for scraping water residue in the cleaning mechanism is arranged on a reciprocating mechanism, and the reciprocating mechanism is arranged on a movable bracket. When the valve is closed, since the connecting channel is connected to the top of the frame, the cleaning mechanism needs to move to the side at this time. When the valve is opened, the connecting channel is retracted. At this time, the cleaning mechanism can be moved to the top of the valve body, so that the scraper is aligned with the inner wall of the valve body, and then the first motor is started to drive the reciprocating mechanism to rotate, and the reciprocating mechanism drives the scraper to perform reciprocating motion in the vertical direction, so that the scraper can continuously scrape the water residue attached to the inner wall of the valve body. Even if it cannot be scraped clean at one time, the cleaning effect can be enhanced by scraping multiple times. The moving range of the scraper is from the bottom of the bracket to the bottom of the valve body, so that the inner wall of the valve body can be cleaned to the greatest extent. When the scraper scrapes the water residue attached to the inner wall, the blowing pump will also send air into the blowing channel. Since the blowing direction of the blowing channel is downward, the water residue scraped by the scraper can be blown downward to make it leave the valve body, and at the same time, it is prevented that the water residue is left in the valve body again or enters and blocks the blowing channel, so as to achieve the purpose of cleaning the inner wall of the valve body;

[0012] Water slag in a high temperature and humid state is likely to leave a part attached to the inner wall of the valve after drying and cooling. If it is not cleaned, it will not only affect the transportation of the water slag, but also affect the closing of the valve. Manual cleaning methods are usually used in the prior art, but manual cleaning is time-consuming and labor-intensive, and not all valves can be cleaned manually. The entire device needs to be stopped during the cleaning process to ensure life safety, and the valve cannot be used for a short period of time, which greatly affects the operating efficiency of the water slag treatment channel. The present invention adopts an automated cleaning mechanism to clean the water slag attached to the inner wall of the valve, and enhances the cleaning effect by scraping with a scraper and blowing with an air pump. Compared with manual cleaning, it is time-saving, labor-saving and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0036] Reference Figure 1-10 As shown, a water slag flap valve comprises a frame 1, on which a valve body 2 and a cleaning mechanism 3 arranged above the valve body 2 and movable are installed, a valve 21 is installed at the bottom of the valve body 2, a foldable connecting channel 4 is installed at the top of the valve body 2, the connecting channel 4 is used to connect the top of the frame 1 and the valve body 2, the cleaning mechanism 3 comprises a bracket 31, the outer side of the bracket 31 is connected to a first motor 32 and a blowing pump 33 connected to the first motor 32, the first motor 32 is connected to a reciprocating mechanism 35, the reciprocating mechanism 35 is connected to a scraper 351 for scraping water slag, the scraper 351 is provided with a blowing channel 352 for blowing downward, and the blowing channel 352 is connected to the blowing pump 33;

[0037] When the cleaning mechanism 3 performs the cleaning operation, the following operations are included:

[0038] Fold the connecting channel 4;

[0039] Move the cleaning mechanism 3 to above the valve body 2, and align the scraper 351 with the inner wall of the valve body 2;

[0040] The first motor 32 is started, and the reciprocating mechanism 35 drives the scraper 351 to perform reciprocating motion in the vertical direction;

[0041] When the valve 21 is closed, the connecting channel 4 is connected to the top of the frame 1, forming a channel from the top of the frame 1 to the inside of the valve body 2. At this time, the valve body 2 and the valve 21 in the closed state can temporarily store water slag. The accumulated water slag will leave the valve 21 under the action of gravity after the valve 21 is opened. However, since the water slag is in a high temperature and humid state when it is accumulated in the valve body 2, it is easy to leave a part of the water slag attached to the inner wall of the valve 21 after drying and cooling, so the cleaning mechanism 3 needs to clean up these attachments;

[0042] The scraper 351 for scraping water residue in the cleaning mechanism 3 is arranged on the reciprocating mechanism 35, and the reciprocating mechanism 35 is arranged on the movable bracket 31. When the valve 21 is closed, since the connecting channel 4 is connected to the top of the frame 1, the cleaning mechanism 3 needs to be moved to the side at this time. When the valve 21 is opened, the connecting channel 4 is retracted. At this time, the cleaning mechanism 3 can be moved above the valve body 2, so that the scraper 351 is aligned with the inner wall of the valve body 2, and then the first motor 32 is started to drive the reciprocating mechanism 35 to rotate, and the reciprocating mechanism 35 drives the scraper 351 to do reciprocating motion in the vertical direction, so that the scraper 351 can continuously scrape the residue attached to the valve body. 2. Even if the water residue on the inner wall cannot be scraped off in one time, the cleaning effect can be enhanced by scraping multiple times. The moving range of the scraper 351 is from the bottom of the bracket 31 to the bottom of the valve body 2, so that the inner wall of the valve body 2 can be cleaned to the greatest extent. When the scraper 351 scrapes the water residue attached to the inner wall, the air pump 33 will also send air into the air blowing channel 352. Since the air blowing direction of the air blowing channel 352 is downward, the water residue scraped off by the scraper 351 can be blown downward to make it leave the valve body 2, and at the same time, the water residue is prevented from being left in the valve body 2 again or entering and blocking the air blowing channel 352, so as to achieve the purpose of cleaning the inner wall of the valve body 2.

[0043] After drying and cooling, a part of the water slag in a high temperature and humid state is likely to remain attached to the inner wall of the valve 21. If it is not cleaned, it will not only affect the transportation of the water slag, but also affect the closing of the valve 21. In the prior art, manual cleaning methods are usually used, but manual cleaning is time-consuming and labor-intensive, and not all valves 21 can be manually cleaned. During the cleaning process of the valve 21, the entire device needs to be stopped to ensure personal safety, and it cannot be used for a short period of time, which greatly affects the operating efficiency of the water slag treatment channel. The present invention adopts an automated cleaning mechanism 3 to clean the water slag attached to the inner wall of the valve 21, and the cleaning effect is enhanced by scraping with a scraper 351 and blowing with an air pump 33. Compared with manual cleaning, it is time-saving, labor-saving and more efficient.

[0044] Further, the connecting channel 4 is arranged directly above the valve body 2, and the connecting channel 4 includes a plurality of folding members 41 which are gradually increased in size from top to bottom and are slidably connected, and the lengths of the plurality of folding members 41 are all the same, and the plurality of folding members 41 include a first folding member 411 which is located at the innermost side after folding, and a second folding member 412 which is located at the outermost side and fixedly connected to the valve body 2 at the bottom, and the tops of the plurality of folding members 41 except the first folding member 411 are all fixedly connected with a first resisting member 413, and the bottoms of the plurality of folding members 41 except the second folding member 412 are all fixedly connected with a second resisting member 414 which abuts against the first resisting member 413, and the top of the first folding member 411 is fixedly connected with a first moving member 415 which abuts against the top of the frame 1;

[0045] A plurality of folding members 41 are combined into a foldable connecting channel 4. When the connecting channel 4 in the folded state needs to be unfolded and connected to the top of the frame 1, the first folding member 411 moves toward the top of the frame 1. After moving to a certain extent, the second abutting member 414 arranged at the bottom of the folding member 41 will abut against the first abutting member 413 arranged at the top of the next-stage folding member 41, thereby driving the next-stage folding member 41 to move toward the top of the frame 1, and so on until the first moving member 415 arranged at the top of the first folding member 411 abuts against the top of the frame 1. At this time, the connecting channel 4 has been unfolded, and the water slag can be transported to the valve body 2 through the connecting channel 4.

[0046] When the connecting channel 4 in the unfolded state needs to be folded, the first folding piece 411 will move toward the valve body 2, and the first moving piece 415 arranged at the top of the first folding piece 411 will contact with the top of the next-level folding piece 41, so that the next-level folding piece 41 also moves toward the valve body 2, until the second contact piece 414 arranged at the bottom of the first folding piece 41 contacts with the top of the valve body 2. At this time, the connecting channel 4 has been completely folded. Because the lengths of the multiple folding pieces 41 are the same, the folded connecting channel 4 is relatively stable. In the process of the folding piece 41 moving toward the valve body 2, the bottom of the folding piece 41 will also contact with the inner wall of the next-level folding piece 41, thereby producing an effect similar to that of the scraper 351, scraping off the water residue attached to the inner wall of the next-level folding piece 41, and so on, thereby cleaning the inner walls of the remaining folding pieces 41 except the first folding piece 411.

[0047] Further, the shape of the inner wall of the valve body 2 when viewed from above is rectangular, the shape of the inner wall of the first folding member 411 when viewed from above is the same as the shape of the inner wall of the valve body 2 when viewed from above, a second motor 11 is installed on the frame 1 and is arranged on the side of the connecting channel 4 away from the cleaning mechanism 3, the second motor 11 is connected to a first synchronous belt 111 facing the side of the connecting channel 4, the first synchronous belt 111 is connected to a first threaded rod 12 rotatably connected to the frame 1, and the first threaded rod 12 is threadedly connected to a second moving member 121 fixedly connected to the first moving member 415;

[0048] The top-view cross-section of the first folding member 411 is the same as the top-view cross-section of the valve body 2, so that after the connecting channel 4 is folded, the scraper 351 of the cleaning mechanism 3 can extend into the valve body 2 and clean the inner wall of the valve body 2, and the scraper 351 can also clean the inner wall of the first folding member 411. The second motor 11 can drive the first threaded rod 12 to rotate through the first synchronous belt 111, and when the threaded rod rotates, it can drive the second movable member 121 that cannot rotate due to the fixed connection with the first movable member 415 to move in the vertical direction, so that the first movable member 415 drives the first folding member 411 to move in the vertical direction, thereby realizing the folding or unfolding of the connecting channel 4.

[0049] Further, the second motor 11 is connected to a chain 112 on the side facing the valve body 2, the chain 112 is connected to a tensioning device 113 and a threaded tube 13, the threaded tube 13 is rotatably connected to a housing 131 for supporting the threaded tube 13, the housing 131 is rotatably connected to an end facing the second motor 11 with a first support member 22 fixedly connected to the valve body 2, the threaded tube 13 is threadedly connected to an end away from the second motor 11 with a second threaded rod 132, the second threaded rod 132 is fixedly connected to an end away from the threaded tube 13 with a second support member 133, the second support member 133 is rotatably connected to a third support member 134, the third support member 134 is rotatably connected to a fourth support member 23 fixedly connected to the valve body 2 and a fifth support member 24 fixedly connected to the valve 21;

[0050] While the connecting channel 4 is folded or unfolded by the second motor 11, the second motor 11 can also drive the valve 21 to move to realize the opening and closing of the valve 21. The second motor 11 drives the threaded tube 13 to rotate through the chain 112, and the relative position of the threaded tube 13 is fixed by the shell 131, so the threaded tube 13 can only rotate and drive the second threaded rod 132 connected by the thread to realize the vertical movement. When the second threaded rod 132 moves, the valve 21 is driven to rotate around the rotation connection between the third support member 134 and the fourth support member 23 through the second support member 133, the third support member 134 and the fifth support member 24 connected in sequence, thereby realizing the opening and closing of the valve 21. When the valve 21 rotates, the threaded tube 13 will produce a slight rotation around the rotation connection between the first support member 22 and the shell 131. In order to maintain the stability of the chain 112 connection, a tensioning device 113 is provided to be connected to the chain 112.

[0051] Further, the reciprocating mechanism 35 includes a first transmission shaft 34, the first transmission shaft 34 is connected to a second synchronous belt 353, the second synchronous belt 353 is connected to a first transmission gear 354 at one end away from the first transmission shaft 34, the first transmission gear 354 is fixedly connected to a coaxially arranged second transmission gear 355, the second transmission gear 355 is connected to a third synchronous belt 356, the second transmission gear 355 is arranged in the middle of the third synchronous belt 356, and two third transmission gears 357 that are equidistant from the second transmission gear 355 are respectively connected to the two sides of the third synchronous belt 356, and the two third transmission gears 357 are fixedly connected to coaxially arranged The sector gear 358 is meshed with a third moving member 359, and only one sector gear 358 is meshed with the third moving member 359 at any time. The third moving member 359 is provided with a plurality of gear teeth 3591 meshed with the two sector gears 358 on both sides, and a hollow 3592 is provided in the middle of the third moving member 359. Two fixing members 36 passing through the hollow 3592 are provided in the bracket 31. The bottom of the third moving member 359 is fixedly connected to the scraper 351. The air pump 33 is connected to a ventilation pipe 331, and the ventilation pipe 331 passes through the bracket 31, the third moving member 359 and the scraper 351 and is communicated with the air blowing channel 352;

[0052] In order to enable the third moving member 359 to maintain movement in the vertical direction, a hollow 3592 is provided on the third moving member 359, and two vertically arranged fixing members 36 are provided to pass through the hollow 3592, thereby limiting the movement direction of the third moving member 359;

[0053] When the second motor 11 drives the first transmission shaft 34 to rotate, the first transmission gear 354 will be driven to rotate in the same direction and at the same speed through the second synchronous belt 353, and then the first transmission gear 354 will simultaneously drive the second transmission gear 355 to rotate in the same direction and at the same speed, and the second transmission gear 355 will drive two third transmission gears 357 to transmit through the third synchronous belt 356, and the two third transmission gears 357 will respectively drive two sector gears 358 to rotate in the same direction and at the same speed, because only one sector gear 358 is meshed with the third moving member 359 at any time, when one sector gear 358 is disengaged from the third moving member 359, the other sector gear 358 will mesh with the third moving member 359, wherein two sector gears 358 with sector surfaces of 150 degrees and the same orientation and number of teeth are preferably selected;

[0054] When the top of the third moving member 359 is at the bottom of the bracket 31, the third moving member 359 meshes with the sector gear 358 on the left side. As the sector gear 358 rotates counterclockwise, the third moving member 359 moves toward the top of the bracket 31, thereby driving the scraper 351 to move toward the top of the bracket 31.

[0055] When the bottom of the third movable member 359 is at the bottom of the bracket 31, the third movable member 359 is meshed with the fan gear 358 on the right. As the fan gear 358 rotates counterclockwise, the third movable member 359 moves toward the bottom of the valve body 2, thereby driving the scraper 351 to move toward the bottom of the valve body 2, thereby realizing the reciprocating motion of the scraper 351 without changing the rotation direction of the second motor 11, thereby enhancing the cleaning effect on the inside of the valve body.

[0056] Furthermore, the scraper 351 includes four scraping blades 3511 with trapezoidal cross-sections, and blades 3512 are provided on the upper and lower sides of the scraper 3511. The blowing channel 352 is arranged at the bottom end of the scraper 3511, and the blowing channels 352 in the four scraper blades 3511 are connected to each other, so that scraping operations can be performed on the upper and lower sides of the scraper 3511. At the same time, the water residue debris scraped from the upper side will move along the inclined surface toward the valve body 2, and will be driven by the gas blown in the blowing channel 352 to move toward the valve body 2 below during the falling process, while the water residue debris scraped from the lower side will be directly driven by the gas blown in the blowing channel 352 to move toward the valve body 2, thereby preventing the water residue debris from entering and blocking the blowing channel 352.

[0057] Further, the air pump 33 includes a fan 332, the fan 332 is fixedly connected to a second transmission shaft 333, the second transmission shaft 333 is connected to a fourth synchronous belt 334 connected to the first transmission shaft 34, the frame 1 is provided with a receiving chamber 14 for accommodating the air pump 33 and the first motor 32, the bottom of the bracket 31 is provided with a roller 37, the frame 1 is also equipped with an electric multi-stage telescopic rod 15 for moving the cleaning mechanism 3 and a track 16 for the roller 37 to roll, the telescopic end 17 of the electric multi-stage telescopic rod 15 is fixedly connected to the bracket 31, the base 18 of the electric multi-stage telescopic rod 15 is arranged in the frame 1, and the bottom of the track 16 is arranged at the same level as the top of the second folding member 412 and is located on the side of the valve body 2 and extends toward the valve body 2;

[0058] When the first motor 32 is started, the fan 332 in the air pump 33 can be driven to rotate through the fourth synchronous belt 334, so that wind is blown out from the blowing channel 352 while the scraper 351 scrapes the water residue, preventing the water residue dust scraped by the scraper 351 from entering the blowing channel 352. Since the cleaning mechanism 3 does not have a conveying channel, the connecting channel 4 is required to use when conveying the water residue, and the working position of the connecting channel 4 conflicts with the working position of the cleaning mechanism 3. Therefore, a roller 37 and an electric multi-stage telescopic rod 15 are designed for moving the cleaning mechanism 3. At the same time, in order to prevent the cleaning mechanism 3 from moving in the wrong direction, a track 16 for limiting the moving direction of the roller 37 is designed on the frame 1.

[0059] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
