DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1 To Attachment Figure 4 As shown:

[0023] Embodiment 1: The utility model provides an exhaust gas filtering device for high-concentration compound fertilizer production, including a main body 1, including a base 101, flange pipes 102 arranged on both sides of the top of the base 101, a filter 103 arranged between the flange pipes 102, and a vent pipe 107 arranged at both ends of the filter 103; a disassembly and assembly mechanism 2, including a sealing cylinder 205 arranged between the flange pipe 102 and the vent pipe 107, a movable plate 204 arranged at the bottom of the sealing cylinder 205, an electromagnetic valve 201 arranged on the flange pipe 102, and a linear drive member arranged between the movable plate 204 and the base 101; a shielding mechanism 3, including a shielding component 301 arranged on the vent pipe 107, and a reset component 302 arranged on the shielding component 301, wherein the filter 103 adopts a polymer plate for filtering, and the filtering effect is good.

[0024] Specifically, the linear drive member includes a bidirectional lead screw 203 disposed in the base 101 , and a motor 202 disposed at the input end of the bidirectional lead screw 203 . The bidirectional lead screw 203 is threadedly connected to the movable plate 204 .

[0025] Furthermore, a support seat 105 is provided at the bottom of the sealing cylinder 205 , and a handle 106 is provided at the top of the sealing cylinder 205 . The support seat 105 can support and limit the position of the filter 103 when the filter 103 is temporarily placed on the ground, thereby ensuring the stability of the filter 103 .

[0026] Furthermore, a limit ring 206 is provided on the inner surface of the sealing cylinder 205 , and a limit seat 104 is provided on the top of the base 101 outside the sealing cylinder 205 .

[0027] As can be seen from the above, during operation, the two flange pipes 102 are respectively connected to the exhaust gas input pipe and the exhaust gas output pipe, and then the filter 103 is placed on the limit seat 104. The limit seat 104 will limit the position of the filter 103 so that the ventilation pipe 107 is aligned with the flange pipe 102, and then the motor 202 is started. The motor 202 will drive the two-way screw rod 203 to rotate, and then drive the two sealing cylinders 205 to separate or move together through the movable plate 204. When the two sealing cylinders 205 are driven to move together, the sealing cylinder 205 will be sleeved on the ventilation pipe 107, and the filter 103 will be clamped in the middle of the device through the limit ring 206 to ensure the stability of the filter 103. The sealing cylinder 205 will be sleeved on the ventilation pipe 107 and the flange pipe 102 at the same time, so as to The filter 103 is sealed and connected to the flange pipe 102. When the exhaust gas filtering process is performed, the solenoid valve 201 is started, and the exhaust gas will enter the filter 103 through the external input pipe, and then the exhaust gas will be adsorbed and filtered by the filter 103, and then the filtered exhaust gas will be discharged through the external output pipe. When the filter 103 needs to be replaced, cleaned and maintained for a long working time, it is only necessary to close the solenoid valve 201, and then drive the two sealing cylinders 205 to separate and move through the motor 202, so that the sealing cylinder 205 is separated from the ventilation pipe 107. The staff can lift the filter 103 by holding the handle 106 to separate the filter 103 from the base 101, which is convenient for personnel to quickly disassemble, assemble and replace the filter 103 and improve work efficiency.

[0028] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the shielding assembly 301 includes a movable ring 3012 arranged on the periphery of the ventilation pipe 107, a cover plate 3013 arranged on the movable ring 3012, a rotating member 3014 arranged between the movable ring 3012 and the cover plate 3013, and a push rod 3011 arranged on the sealing cylinder 205.

[0029] Specifically, the reset assembly 302 includes a spring 3021 disposed between the movable ring 3012 and the filter 103 , and a torsion spring 3022 disposed between the cover plate 3013 and the rotating member 3014 .

[0030] As can be seen from the above, when the filter 103 is not in use or after use, the cover plate 3013 will block and seal the vent of the vent pipe 107 to prevent the filter material inside the filter 103 from being exposed to the outside and affecting its life or the filtered impurities from flying out and affecting the environment. When the motor 202 drives the two sealing cylinders 205 to move together, the push rod 3011 will push the movable ring 3012 to move synchronously. When the movable ring 3012 moves, it will push the cover plate 3013 open through the vent pipe 107, so that it can be rotated open by the rotating member 3014, thereby revealing the vent of the vent pipe 107, which is convenient for personnel to install the filter 103. 02 When the two sealing cylinders 205 are driven to separate and move, the push rod 3011 will be driven to move synchronously. The spring 3021 will use its own elasticity to push the movable ring 3012 to move synchronously due to the disappearance of resistance, until the movable ring 3012 moves to the boundary of the ventilation pipe 107, and the cover plate 3013 will protrude from the ventilation pipe 107. The torsion spring 3022 will drive the cover plate 3013 to rotate and close due to the disappearance of resistance, so that it coincides with the vent of the ventilation pipe 107. When the filter 103 is disassembled, the cover plate 3013 can be automatically reset to seal the filter 103 at the first time without the need for manual adjustment by the staff, thereby improving work efficiency and facilitating use by personnel.
