[0020] Please see Figure 1-5 This utility model provides the following technical solution: a particle drying exhaust gas filtration device, including a gas supply pipe 1 and a threaded pull rod 5, and also including a protective shell 2 and a mounting plate 3. A filter screen 33 is installed on the mounting plate 3. Two mounting plates 3 are hinged together and the mounting plate 3 is slidably installed on the gas supply pipe 1. Several fixing blocks 21 are installed on the side wall of the groove of the gas supply pipe 1 and the mounting plate 3 by means of springs. The mounting plate 3 is provided with a groove that cooperates with the fixing blocks 21. A limiting groove 32 is provided on the side wall of the mounting plate 3 and a limiting frame 34 that cooperates with the limiting groove 32 is installed on the side wall of the groove of the mounting plate 3 by means of an electric telescopic rod. The protective shell 2 is hinged to the gas supply pipe 1 on both sides of the groove of the mounting plate 3 by means of a torsion spring shaft. The opposite side walls of the two protective shells 2 on the same side are respectively provided with a cooperating cam 21 and a groove. The side wall of the mounting plate 3 is provided with a threaded hole. A threaded pull rod 5 is installed on the threaded hole of the side wall of the mounting plate 3. The side wall of the protective shell 2 is provided with a groove that cooperates with the threaded pull rod 5.

[0021] The gas supply pipe 1 is used to supply exhaust gas, and the filter screen 33 is used to filter particulate matter in the exhaust gas. During the process of exhaust gas passing through the filter screen 33, particulate matter in the exhaust gas is filtered out. The clean airflow leaves the gas supply pipe 1 after passing through the filter screen 33, and the filtered impurities adhere to the filter screen 33. The mounting plate 3 is used to install the filter screen 33. The area of ​​the mounting plate 3 is larger than the area of ​​the inner wall of the gas supply pipe 1. After the filter screen 33 is installed on the gas supply pipe 1, the edge of the groove for installing the filter screen 33 on the mounting plate 3 is positioned inside the side wall of the gas supply pipe 1 to prevent airflow from passing through the gap between the mounting plate 3 and the filter screen 33, thus ensuring the working effect of the filter screen 33. The limiting groove 32 and the limiting frame 34 on the side wall of the mounting plate 3 cooperate... The mounting plate 3 serves to fix the mounting plate 3, ensuring its stability during device use. The cooperation between the limiting groove 32 and the limiting frame 34 also seals the gap between the mounting plate 3 and the side wall of the groove, preventing leakage. The sealing gasket on the side wall of the limiting frame 34 enhances its sealing effect. The side wall of the groove for installing the filter screen 33 on the mounting plate 3 has a protrusion, and the side wall of the filter screen 33 has a groove that matches the protrusion of the groove. The protrusion of the groove for installing the filter screen 33 acts as a limit, making it easy for the user to install the filter screen 33 in the appropriate position. When the two mounting plates 3 are installed together, the user can move the mounting plate 3. The used filter 33 will detach from the air supply pipe 1 along with the mounting plate 3. As the mounting plate 3 moves, the new filter 33 is installed on the air supply pipe 1, realizing the replacement of the filter 33. The cooperation between the fixing block 31 and its matching groove plays a limiting role, ensuring the stability of the mounting plate 3 during the use of the device. The side wall shape of the fixing block 31 is inclined, ensuring that the mounting plate 3 can smoothly push the fixing block 31 during the movement, ensuring that the movement of the mounting plate 3 is not hindered. The spring set on the fixing block 31 ensures that the fixing block 31 can quickly return to its original position after being pushed, ensuring the working effect of the fixing block 31. The two mounting plates 3 are hinged together, and the shape of the mounting plate 3 ensures that the mounting plate 3 is connected by the fixing block 31. When the mounting plate 3 is fixed in place with the corresponding groove, the hinge axis of the mounting plate 3 is located on the outside of the gas supply pipe 1. At this time, the user can move the mounting plate 3 located on the outside of the gas supply pipe 1 to a position parallel to the side wall of the gas supply pipe 1, reducing the space occupied by the unused mounting plate 3. The protective shell 2 is hinged to both sides of the groove on the gas supply pipe 1 where the mounting plate 3 is installed. When the device is in use, rotate the protective shell 2 so that the two protective shells 2 are put together. At this time, the protective shell 2 forms a sealed frame, ensuring that the groove on the gas supply pipe 1 where the mounting plate 3 is installed will not be connected to the outside during the movement of the mounting plate 3, avoiding leakage of exhaust gas. This allows the device to replace the mounting plate 3 without stopping the airflow. The side wall of the mounting plate 3 fits against the inner wall of the combined protective shell 2.To ensure that unfiltered airflow does not leave the air supply pipe 1 through the gap between the mounting plate 3 and the protective shell 2 without filtration, the opposite sidewalls of the protective shell 2 are provided with matching protrusions and grooves. Sealing gaskets are provided on the opposite sidewalls of the protective shell 2 and the sidewalls at the hinge point of the protective shell 2, ensuring the airtightness of the frame formed by the two protective shells 2. When the two protective shells 2 are joined together, rotating the cam 21, through the cooperation of the cam 21 and its matching groove, fixes the joined protective shells 2, ensuring their stability. The installation method of the protective shell 2 ensures that it is in close contact with the air supply pipe 1 when stationary. The sidewall design reduces the space occupied by the protective shell 2. When the user moves the mounting plate 3, the threaded rod 5 is installed on the mounting plate 3 via threads. When the protective shell 2 is closed, the threaded rod 5 is located inside the groove on the sidewall of the protective shell 2. At this time, the user can pull the mounting plate 3 through the threaded rod 5. The position of the threaded rod 5 ensures that the threaded rod 5 is always inside the groove where the protective shell 2 and the threaded rod 5 mate during the movement of the mounting plate 3. At this time, the protective shell 2 is in a sealed state. The side of the mounting plate 3 without the threaded rod 5 has a sealing plug on the protective shell 2, ensuring the airtightness of the protective shell 2.

[0022] Specifically, pin holes 41 are provided on the side walls of the grooves for mounting the hinge shafts on the two mounting plates 3, and fixing pins 4 are installed on the pin holes 41 provided on the two mounting plates 3.

[0023] The two mounting plates 3 hinged together can be fixed by the cooperation of the fixing pin 4 and the pin hole 41, ensuring the stability of the mounting plates 3. The protrusions on the side wall of the fixing pin 4 are perpendicular to each other. The position of the protrusions on the side wall of the fixing pin 4 ensures that when the two mounting plates 3 are rotated to a mutually perpendicular state, the mounting plates 3 can still be fixed by the cooperation of the fixing pin 4 and the pin hole 41. When the two mounting plates 3 are perpendicular to each other, the mounting plate 3 located outside the gas pipe 1 is parallel to the side wall of the gas pipe 1, ensuring the stability of the mounting plate 3 in the storage state.

[0024] Specifically, the protective shell 2 has a fixing groove 24 on the protruding side wall of the end face, and a pull block 23 is installed on the side wall of the fixing groove 24 by a spring. The air pipe 1 has a fixing block 22 that cooperates with the fixing groove 24 on the side wall.

[0025] Pull block 23 is slidably mounted on the side wall of fixing slot 24 by a spring. The end face of fixing block 22 is beveled. When the user rotates the protective shell 2 to a position parallel to the side wall of the air pipe 1, fixing block 22 pushes pull block 23, ensuring that pull block 23 does not obstruct fixing block 22 from entering fixing slot 24. The spring on pull block 23 ensures that the pushed pull block 23 can quickly return to its original position. Pull block 23, which returns to its original position, serves to fix fixing block 22, ensuring that the protective shell 2, which is rotated to a position parallel to the side wall of the air pipe 1, can be fixed, further improving the stability of the protective shell 2. Pull plate penetrating the side wall of the protective shell 2 is provided on the side wall of pull block 23. Force groove is provided on the side wall pull plate of pull block 23. Force groove is provided on the side wall pull plate of pull block 23, which makes it easy for the user to move pull block 23, making it easy for the user to release the fixation of pull block 23 to fixing slot 24, and making it easy for the user to adjust the position of the protective shell 2.

[0026] Specifically, a plate 25 is slidably mounted on the groove of the mounting cam 21 of the protective shell 2, and a groove is provided on the side wall opposite to the cam 21 to cooperate with the plate 25. A sealing plate 26 is installed on the side wall of the groove that cooperates with the plate 25 by means of a spring.

[0027] When the user rotates the cam 21, the cam 21 pushes the insert plate 25, causing the insert plate 25 to enter the groove that it mates with. The mating of the insert plate 25 and the groove ensures the stability of the protective shell 2 when they are together. During the process of the insert plate 25 entering the groove, the spring on the sealing plate 26 is compressed. When the user rotates the cam 21 in the opposite direction to release the push of the cam 21 on the insert plate 25, the sealing plate 26 pushes the insert plate 25 under the action of the spring, realizing the automatic reset of the insert plate 25, which makes it easy for the user to separate the protective shell 2. The shape of the sealing plate 26 ensures that when the sealing plate 26 moves to the limit position under the action of the spring, the side wall of the sealing plate 26 is flush with the side wall of the protective shell 2, ensuring that the sealing plate 26 can completely push the insert plate 25 away from the groove it mates with.

[0028] Specifically, the insert plate 25 has a protrusion at the position corresponding to the cam 21, and the side wall protrusion of the insert plate 25 is located below the rotation axis of the corresponding cam 21.

[0029] The side wall protrusion of the insert plate 25 serves as a limit. When the cam 21 engages with the side wall protrusion of the insert plate 25, the cam 21 is in a downward tilted state. After the cam 21 pushes the insert plate 25 into the groove it engages with, the insert plate 25 tends to move into the groove where the insert plate 25 is installed under the action of the spring. At this time, the downward tilting cam 21 is blocked by the side wall protrusion of the insert plate 25, ensuring that the cam 21 will not be pushed downward and rotated. The cam 21 is fixed, thereby ensuring the stability of the insert plate 25.

[0030] Specifically, a protective net 35 is provided at the hinge of the mounting plate 3.

[0031] The protective net 35 serves to seal the gap at the hinge of the mounting plates 3, ensuring that the airflow will not pass through the gap between the mounting plates 3 during the movement of the mounting plates 3, thus ensuring the working effect of the device. The protective net 35 is elastic, and during the rotation of the mounting plates 3, the protective net 35 undergoes elastic deformation, ensuring that the rotation of the mounting plates 3 is not hindered.

[0032] Specifically, the top and bottom surfaces of the mounting plate 3 are provided with protrusions at the ends away from the hinge axis, and the edge of the groove on which the gas pipe 1 is mounted on the mounting plate 3 is provided with a groove that matches the protrusion on the side wall of the mounting plate 3.

[0033] The cooperation between the side wall protrusion of the mounting plate 3 and the side wall groove of the slot for mounting the gas pipe 1 serves as a limit, ensuring that the mounting plate 3 will not disengage from the groove of the mounting plate 3 during movement, thus ensuring the stability of the mounting plate 3 during movement.

[0034] The working principle and usage process of this utility model are as follows: Waste gas is sent into the interior of the gas transmission pipe 1. As the airflow flows, the filter screen 33 filters the particulate matter in the waste gas. The filtered airflow leaves the gas transmission pipe 1. When replacing the filter screen 33, remove the fixing pin 4, release the fixing of the hinged mounting plate 3, rotate the mounting plate 3 located outside the gas transmission pipe 1 to a position perpendicular to the side wall of the gas transmission pipe 1, install the fixing pin 4 on the pin hole 41, and the mounting plate 3 is fixed. Install the new filter screen 33 on the mounting plate 3 located outside the gas transmission pipe 1, install the threaded pull rod 5 on the threaded hole on the side wall of the mounting plate 3 located inside the gas transmission pipe 1, pull the pull block 23 to release the fixing of the pull block 23 to the fixing block 22, rotate the protective shell 2, and the two protective shells 2 come together. Rotate the cam 21, and the insert plate 25 enters the interior of the groove it mates with under the pushing action of the cam 21. The combined protective shells 2 are fixed. The electric telescopic rod carries the limiting frame 34 out of the limiting groove. 32. The mounting plate 3 is released from its fixed position. The mounting plate 3 is moved by the threaded rod 5. The moving mounting plate 3, along with the used filter screen 33, is removed from the air supply pipe 1. The new filter screen 33 is brought into the air supply pipe 1, realizing the replacement of the filter screen 33. The moved mounting plate 3 is fixed by the cooperation of the fixing block 2 31 and the corresponding groove. The limiting frame 34 is moved into the limiting groove 32. The cam 21 is rotated in the opposite direction. The pushing action of the cam 21 on the insert plate 25 is released. The insert plate 25 is then held in place by the spring and the sealing plate 2. With the cooperation of 6, it enters the groove of the mounting plate 25. The fixing between the cooperating protective shells 2 is released, and the protective shell 2 is rotated back to its original position. As the protective shell 2 rotates, the fixing block 22 pushes the pull block 23. When the protective shell 2 is in contact with the air pipe 1, the pushing of the fixing block 22 on the pull block 23 is released, and the pull block 23 returns to its original position under the action of the spring. The protective shell 2 is fixed. The used filter screen 33 is removed and cleaned. The mounting plate 3 is rotated to a state parallel to the side wall of the air pipe 1.
