[0002] As the name implies, the wind blocking roller can play a role in blocking the normal flow of wind. By slowing down the flow speed of the wind, a certain specific effect can be achieved. For example, in some incineration equipment, a filter plate is fixedly installed on the wind blocking roller, so as to extend the residence time of the incineration gas through the wind blocking roller, and make it fully contact with the filter plate, so as to achieve the purpose of filtering the gas.
[0003] After long-term use, a large amount of dust and debris will adhere to the filter plate fixedly installed on the wind blocking roller, and the internal space of the ventilation duct is mostly narrow. If the filter plate cannot be disassembled and replaced in time and quickly, it will cause the staff to stay in the ventilation duct for a long time, which will not only affect the subsequent filtering effect, but also may endanger the physical health of the staff.

Specific embodiments
[0022] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.
[0023] As Figures 1-6 shown, the present utility model provides a technical solution: a combined air-blocking roller that is convenient for splicing, including a base 1, on which a main body 2 of the air-blocking roller is rotatably installed, a limiting platform 3 is installed above the main body 2 of the air-blocking roller, a plurality of connecting grooves 4 are opened on both the main body 2 of the air-blocking roller and the limiting platform 3, an air-blocking vane 5 is slidably installed on the main body 2 of the air-blocking roller through the connecting groove 4, the air-blocking vane 5 is designed to be hollow, a filter plate 18 is inserted into the air-blocking vane 5, a plurality of through holes 19 are opened on the air-blocking vane 5, and the contact surface between the gas and the filter plate 18 is enlarged through the through holes 19, thereby improving the filtering effect, and the way of inserting the filter plate 18 into the air-blocking vane 5 can facilitate the staff to replace the filter plate 18.
[0024] Fixed grooves 6 are provided on the groove walls on both sides of the connecting groove 4, a fixed plate 7 is connected inside the limit platform 3, an open groove 8 is provided at the position where the connecting groove 4 is provided on the limit platform 3, a threaded rod 9 is threadedly connected above the limit platform 3, a rotating wheel 10 is connected to one end of the threaded rod 9, and a circular plate 11 is connected to the other end of the threaded rod 9, a guide groove 12 is provided on the circular plate 11, a rectangular groove 13 is provided on the fixed plate 7, a sliding plate 14 is slidably connected in the rectangular groove 13, limited grooves 26 are provided on the groove walls on both sides of the rectangular groove 13, limited blocks 27 are connected on both sides of the sliding plate 14, the limit blocks 27 slide in the limit grooves 26, when the sliding plate 14 moves in the rectangular groove 13, the limit blocks 27 will slide in the limit grooves 26, thereby guiding and limiting the movement of the sliding plate 14, avoiding the sliding plate 14 from tilting during movement, and preventing the sliding plate 14 from escaping from the rectangular groove 13.
[0025] A limiting plate 15 is connected to the sliding plate 14, and a connecting rod 16 is connected above the sliding plate 14. The connecting rod 16 is slidably connected to the guide groove 12. A sliding sleeve 28 is slidably connected to the connecting rod 16. The sliding sleeve 28 slides in the guide groove 12. The guide groove 12 is an arc-shaped design. When the circular plate 11 rotates and moves downward, the sliding sleeve 28 will slide in the connecting rod 16 and the guide groove 12 at the same time, and the arc-shaped guide groove 12 will push the connecting rod 16, thereby causing the limiting plate 15 to abut against the top of the connecting strip 17, thereby fixing the position of the connecting strip 17 in the connecting groove 4.
[0026] A connecting strip 17 is connected to one side of the wind-blocking blade 5. The connecting strip 17 is T-shaped and is slidably connected to the connecting groove 4. A spring 24 is connected inside the connecting strip 17. A fixing block 25 is connected to one end of the spring 24. The fixing block 25 slides in the connecting strip 17 and engages with the fixing groove 6. The elastic force of the spring 24 enables the fixing block 25 to engage with the fixing groove 6, which can prevent the connecting strip 17 from sliding in the connecting groove 4 and can remind the staff that the connecting strip 17 has been installed in place, thereby preventing the connecting strip 17 from blocking the opening groove 8 and affecting the movement of the limiting plate 15.
[0027] A baffle plate 20 is rotatably connected to one side above the choke blade 5, and a fixing rod 21 is connected to the other side above the choke blade 5. A hook plate 22 is connected to the baffle plate 20, and torsion springs 23 are connected to both sides of the baffle plate 20. One end of the torsion spring 23 is connected to the choke blade 5. The hook plate 22 is made of rubber and is buckled on the fixing rod 21. When the baffle plate 20 is rotated to open the choke blade 5, the torsion spring 23 will be twisted, so that the baffle plate 20 can be kept in a closed state through the rotation of the torsion spring 23, and the staff can squeeze the hook plate 22 to deform the rubber hook plate 22, so that it is buckled on the fixing rod 21 to fix the baffle 20, thereby preventing the filter plate 18 from sliding and falling.
[0028] The working principle of the utility model is:
[0029] The staff first rotates the baffle 20 and inserts the filter plate 18 into the wind-blocking vane 5. When the baffle 20 rotates, the torsion spring 23 will be twisted. Thus, through the rotation of the torsion spring 23, the baffle 20 blocks the filter plate 18, and at the same time presses the hook plate 22, so that the hook plate 22 is buckled on the fixed rod 21 to prevent the baffle 20 from accidentally rotating. After that, the connecting bar 17 is pushed into the connecting groove 4. At this time, the fixed block 25 will be pushed into the inside of the connecting bar 17 by the groove wall of the connecting groove 4 to compress the spring 24. Then, by using the rebound of the spring 24, the fixed block 25 is pushed into the fixed groove 6 to position and fix the connecting bar 17 to prevent the connecting bar 17 from sliding. After that, by turning the rotating wheel 10 to rotate the threaded rod 9, the threaded rod 9 can push the circular plate 11 downward and drive the circular plate 11 to rotate at the same time. As the circular plate 11 rotates, the guide groove 12 pushes the connecting rod 16 to move, thereby driving the sliding plate 14 to slide in the rectangular groove 13, prompting the limiting plate 15 to extend from the opening groove 8 and abut against the upper part of the connecting bar 17, so as to fix the wind-blocking vane 5. Moreover, the operation is simple and convenient, which can facilitate the staff to quickly disassemble and install the wind-blocking vane 5 and replace the filter plate 18.

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 components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
[0031] The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the gist of this patent.
