Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-6The multi-stage water mist spray structure of the mine wet dust collector includes: a dust collection tower body 1 and a tower cover 2. A sewage discharge pipe is fixedly installed at the bottom of the dust collection tower body 1, an air inlet pipe is fixedly installed on the tower body of the dust collection tower body 1, and an exhaust pipe is fixedly installed on the top of the tower cover 2. A sealing gasket is fixedly installed at the bottom of the tower cover 2, with the bottom of the sealing gasket contacting the top of the dust collection tower body 1 to ensure sealing performance. Multiple primary spray pipes 5 and multiple secondary spray pipes 3 are provided inside the dust collection tower body 1. The multiple primary spray pipes 5 are all located below the multiple secondary spray pipes 3, and two first connectors are fixedly installed on the top of the multiple primary spray pipes 5. The top of each of the multiple secondary spray pipes 3 is fixedly equipped with two second connecting plates 8. Each of the two connecting plates 7 has a positioning post 9 fixedly installed on its top. The tops of the two positioning posts 9 are fixedly connected to the inner wall of the tower cover 2. The two positioning posts 9 pass through the two second connecting plates 8 respectively and are fixedly connected to the corresponding second connecting plates 8. This allows the primary spray pipes 5 and secondary spray pipes 3 to be fixed inside the tower cover 2. By separating the tower cover 2 from the dust collector tower body 1, the primary spray pipes 5 and secondary spray pipes 3 can be taken out of the dust collector tower body 1, thus eliminating the need for personnel to enter the dust collector tower body 1 for cleaning and maintenance. Furthermore, the multiple primary spray pipes 5... Multiple flared nozzles 6 are fixedly installed at the bottom of each of the multiple secondary spray pipes 3, and multiple atomizing nozzles 4 are fixedly installed at the bottom of each secondary spray pipe 3. The flared nozzles 6 can spray water columns with a certain coarseness to intercept large dust particles, while the atomizing nozzles 4 spray fine water mist to intercept even finer dust particles, thus achieving a multi-stage spraying effect and improving the purification effect. An open box body 16 is fixedly installed on one side of the outer wall of the dust removal tower 1, and a lifting screw 17 is rotatably installed inside it. A first drive motor is fixedly installed at the bottom of the open box body 16, and its output shaft is fixedly connected to the bottom end of the lifting screw 17. A lifting seat 18 is threaded onto the screw 17. A mounting frame 20 is fixedly mounted on the lifting seat 18, and a reversing shaft 21 is rotatably mounted on the top of the mounting frame 20. Two fixed arms 22 are fixedly mounted on the reversing shaft 21. The side of the two fixed arms 22 away from the reversing shaft 21 is fixedly connected to the tower cover 2. In this way, the tower cover 2 can be separated from the dust collector tower body 1 by the cooperation between the lifting screw 17 and the lifting seat 18. Then, by rotating the reversing shaft 21, the tower cover 2 can be rotated out from the top of the dust collector tower body 1, and the tower cover 2 can be lowered to a lower position, which facilitates external cleaning personnel to carry out cleaning and maintenance work.

[0023] In the above method, in order to smoothly inject spray water into the primary spray pipes 5 and secondary spray pipes 3, a first connecting pipe is fixedly installed at the top of each of the primary spray pipes 5, and the same primary water pipe 11 is fixedly installed at the top of each of the primary connecting pipes. A second connecting pipe is fixedly installed at the top of each of the secondary spray pipes 3, and the same secondary water pipe 10 is fixedly installed at the top of each of the secondary connecting pipes. A first water pump 12 and a second water pump 13 are fixedly installed on the outer wall of the tower cover 2. The outlet port of the first water pump 12 and the primary water pipe 11 are connected by a first liquid guide pipe 14. The first liquid guide pipe 14 is fixedly connected to the tower cover 2, and the outlet port of the second water pump 13 is connected to the secondary water pipe 10 through the second liquid guide pipe 15. The second liquid guide pipe 15 is fixedly connected to the tower cover 2. The inlet ports of the first water pump 12 and the second water pump 13 are both fixedly installed with pumping pipes. Two external pipes are fixedly installed on the dust removal tower body 1. The bottom ends of the two pumping pipes are fixedly connected to the corresponding external pipes through flanges. The external pipes can be connected to an external water storage tank, so that spray water can be drawn by starting the first water pump 12 and the second water pump 13.

[0024] In this method, in order to drive the reversing shaft 21 to rotate so that the tower cover 2 can rotate, a connecting column 19 is fixedly installed on the top of the lifting seat 18. The top of the connecting column 19 is fixedly connected to the mounting frame 20. A second drive motor is fixedly installed inside the mounting frame 20, and its output shaft is fixedly connected to the bottom end of the reversing shaft 21.

[0025] In this method, in order to achieve a stable installation of the first water pump 12 and the second water pump 13, two load-bearing folding platforms are fixedly installed on the outer wall of the tower cover 2, and the tops of the two load-bearing folding platforms are fixedly connected to the bottoms of the first water pump 12 and the second water pump 13, respectively.

[0026] The working principle of the multi-stage water mist spray structure of the mine wet dust collector provided by this utility model is as follows:

[0027] In this spray structure, two external pipes are connected to an external water storage tank, and the sewage pipe at the bottom of the dust removal tower 1 is connected to an external sewage tank.

[0028] When purifying the air in the mine, outside air enters the dust removal tower 1 through the air intake pipe on the dust removal tower 1. At this time, the first water pump 12 and the second water pump 13 are turned on. First, the flared nozzle 6 located at the bottom sprays out a water column with a certain thickness, which can intercept most of the large dust particles. Then, as the air continues to rise, the atomizing nozzle 4 located at the top sprays out fine water mist, which can capture PM2.5 particles, thereby completing the dust removal and purification of the air. Finally, the purified air is discharged through the exhaust pipe at the top of the tower cover 2.

[0029] In subsequent use, when cleaning and maintenance of the flared nozzle 6 and atomizing nozzle 4 are required, the flanges between the two water pipes and the external pipe can be unscrewed. Then, the first drive motor is started in the forward direction, and its output shaft drives the lifting screw 17 to rotate. The lifting seat 18 then lifts the mounting frame 20 and the tower cover 2, causing the tower cover 2 to gradually separate from the dust removal tower body 1. After the bottom of the flared nozzle 6 is higher than the top end face of the dust removal tower body 1, the first drive motor is turned off first, and then the second drive motor is started in the forward direction. Its output shaft drives the reversing shaft 21 to rotate, so that the tower cover 2, along with the first-stage spray pipe 5 and the second-stage spray pipe 3, rotates under the linkage of the fixed arm 22. After the two have rotated 180°, the second drive motor is turned off. Then, the first drive motor is started in the reverse direction, and the lifting seat 18 lowers the tower cover 2. After the lifting seat 18 has lowered to the lowest position, the first drive motor is turned off. At this time, the first-stage spray pipe 5 and the second-stage spray pipe 3 are in a lower position, and then the cleaning and maintenance personnel can perform cleaning and maintenance on the side.

[0030] After cleaning and maintenance, start the first drive motor in the forward direction. The lifting seat 18 lifts the tower cover 2. After raising the flared nozzle 6 above the top end face of the dust removal tower body 1, start the second drive motor in the reverse direction. After the tower cover 2 rotates 180°, turn off the second drive motor. Then, start the first drive motor in the reverse direction. The lifting seat 18 lowers the tower cover 2 until the sealing gasket at the bottom of the tower cover 2 contacts the top end face of the dust removal tower body 1. Then, turn off the first drive motor. This completes the cleaning and maintenance of the flared nozzle 6 and the atomizing nozzle 4. Then, re-fix the two water pipes and the external pipe, and the spray dust suppression work can continue.

[0031] Compared with related technologies, the multi-stage water mist spray structure of the mine wet dust collector provided by this utility model has the following beneficial effects:

[0032] This utility model provides a multi-stage water mist spraying structure for a mining wet dust collector. It features a detachable dust collector tower body 1 and tower cover 2. A primary spray pipe 5 and a secondary spray pipe 3 are fixed inside the tower cover 2. By starting the first drive motor, the primary spray pipe 5 and secondary spray pipe 3 can be pulled out of the dust collector tower body 1 via the threaded engagement between the lifting seat 18 and the lifting screw 17. Then, by rotating the reversing shaft 21, they rotate out from the top of the dust collector tower body 1. Finally, the lowering of the lifting seat 18 brings them to a lower position, allowing for cleaning and maintenance of the flared nozzle 6 and atomizing nozzle 4 from outside the dust collector tower body 1. This eliminates the need for personnel to enter the dust collector tower body 1 for cleaning and maintenance, reducing the risk factor during the cleaning process and improving cleaning efficiency.
