Description

Technical Field

[0001] This utility model relates to the field of conveyor fan technology, and in particular to a material isolation mechanism and a conveyor fan containing the mechanism. Background Technology

[0002] Conveying blowers use the rotational force of a fan to accelerate fluids. When the impeller rotates, it draws in surrounding air and materials to generate airflow, which blows up the surrounding air and applies pressure, thereby transporting it to the target location. When the conveying blower is turned off, a material isolation mechanism is usually installed to prevent materials from flowing back into the blower.

[0003] In the existing technology, most material isolation mechanisms use simple gate plates for isolation. The gate plates and isolation frames are mostly difficult to disassemble, making the maintenance of the isolation mechanism inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a material isolation mechanism and a conveying fan containing the mechanism, so as to solve the problem mentioned in the background art that the gate plate and the isolation frame are mostly difficult to disassemble, making the maintenance of the isolation mechanism inconvenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes an installation mechanism comprising an isolation frame, a flange plate, a moving groove, a first mounting thread groove, and a sealing groove. A disassembly mechanism is provided at the top of the installation mechanism, comprising a protective shell, a mounting plate, mounting bolts, a stabilizing plate, a rotating rod, a drive motor, a threaded rod, and a sealing ring. An isolation plate mechanism is provided at the bottom of the disassembly mechanism, comprising a gate plate, an adjusting thread groove, a mounting groove, a second mounting thread groove, a rubber plate, a mounting block, a third mounting thread groove, and mounting screws.

[0006] In a preferred embodiment, both ends of the isolation frame are fixedly connected to one end of the flange plate, the interior of the isolation frame has a moving groove, the top of the isolation frame has a first mounting thread groove, and the top of the isolation frame has a sealing groove.

[0007] In a preferred embodiment, the top of the isolation frame is movably connected to the bottom of the protective shell, both sides of the protective shell are fixedly connected to one side of the mounting plate, the inner wall of the mounting plate is movably connected to the outer wall of the mounting bolt, and the outer wall of the mounting bolt is threadedly connected to the inner wall of the first mounting thread groove.

[0008] In a preferred embodiment, the inner wall of the protective shell is fixedly connected to both sides of the stabilizing plate, the inner wall of the stabilizing plate is rotatably connected to the outer wall of the rotating rod via a bearing, the top of the rotating rod is fixedly connected to the output end of the drive motor via a coupling, the bottom end of the rotating rod is fixedly connected to the top end of the threaded rod, the bottom of the protective shell is fixedly connected to the top of the sealing ring, and the outer wall of the sealing ring is movably connected to the inner wall of the sealing groove.

[0009] In a preferred embodiment, the bottom of the threaded rod is movably connected to the top of the gate plate, the gate plate has an adjusting threaded groove inside, and the inner wall of the adjusting threaded groove is threadedly connected to the outer wall of the threaded rod. The outer wall of the gate plate is movably connected to the inner wall of the protective shell and the moving groove.

[0010] In a preferred embodiment, the gate plate has mounting grooves at all four corners on both sides, and the inner wall of the mounting grooves has a second mounting thread groove. Both sides of the gate plate are movably connected to one side of the rubber plate, and the four corners of the rubber plate are fixedly connected to one side of the mounting block. The mounting block has a third mounting thread groove inside.

[0011] In a preferred embodiment, the inner wall of the third mounting threaded groove is movably connected to the outer wall of the mounting screw, the outer wall of the mounting block is movably connected to the inner wall of the mounting groove, and the inner wall of the second mounting threaded groove is threadedly connected to the outer wall of the mounting screw.

[0012] A conveying fan equipped with the aforementioned material isolation mechanism.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the isolation frame is installed on one side of the conveying fan via a flange plate. Before shutting down the fan, the drive motor is first started, which drives the rotating rod to rotate under the stabilization of the stabilizing plate. This, in turn, drives the threaded rod to rotate. The rotation of the threaded rod causes the gate plate to move downward through the threaded connection between the threaded groove and the threaded rod, so that the gate plate moves from the inside of the protective shell to the inside of the moving groove, thereby isolating the inside of the isolation frame. When the device is under maintenance, the installation bolts are removed using tools, so that the protective shell and the isolation frame are released from the locked state. At the same time, the sealing ring is moved away from the inside of the sealing groove, and the disassembly mechanism and the isolation plate mechanism can be removed, which facilitates the maintenance of the device. At the same time, the protective shell avoids the phenomenon of the traditional gate plate being exposed to the outside.

[0014] 2. In this utility model, when material backflow or dusty gas impacts the gate plate, it will first contact the rubber plate. Using tools, the mounting screws are removed so that they are moved away from the inside of the second and third mounting thread grooves, thus freeing the rubber plate from its locked state. The damaged rubber plate can then be removed and replaced, preventing direct contact between debris and the gate plate. This avoids the need for complete replacement of the gate plate as in traditional methods, reducing maintenance costs. Attached Figure Description

[0019] In one embodiment, both ends of the isolation frame 101 are fixedly connected to one end of the flange plate 102. The interior of the isolation frame 101 has a moving groove 103. The top of the isolation frame 101 has a first mounting thread groove 104 and a sealing groove 105. The top of the isolation frame 101 is movably connected to the bottom of the protective shell 201. Both sides of the protective shell 201 are fixedly connected to one side of the mounting plate 202. The inner wall of the mounting plate 202 is movably connected to the outer wall of the mounting bolt 203. The outer wall of the mounting bolt 203 is threadedly connected to the inner wall of the first mounting thread groove 104.

[0020] Specifically: Using tools to remove the mounting bolts 203, the protective shell 201 and the isolation frame 101 are released from the locked state, and the sealing ring 208 is moved away from the inside of the sealing groove 105, thereby removing the disassembly mechanism 2 and the isolation plate mechanism 3, which facilitates the maintenance of the device.

[0021] In one embodiment, the inner wall of the protective shell 201 is fixedly connected to both sides of the stabilizing plate 204, the inner wall of the stabilizing plate 204 is rotatably connected to the outer wall of the rotating rod 205 through a bearing, the top of the rotating rod 205 is fixedly connected to the output end of the drive motor 206 through a coupling, the bottom end of the rotating rod 205 is fixedly connected to the top end of the threaded rod 207, the bottom of the protective shell 201 is fixedly connected to the top of the sealing ring 208, and the outer wall of the sealing ring 208 is movably connected to the inner wall of the sealing groove 105.

[0022] Specifically, the sealing effect of the protective shell 201 is enhanced by the setting of the sealing ring 208 and the sealing groove 105.

[0023] In one embodiment, the bottom of the threaded rod 207 is movably connected to the top of the gate plate 301, the gate plate 301 has an adjusting threaded groove 302 inside, and the inner wall of the adjusting threaded groove 302 is threadedly connected to the outer wall of the threaded rod 207. The outer wall of the gate plate 301 is movably connected to the inner wall of the protective shell 201 and the moving groove 103.

[0024] Specifically, when material flows back or dusty gas impacts the gate plate 301, it will first come into contact with the rubber plate 305, preventing debris from directly contacting the gate plate 301.

[0025] In one embodiment, the gate plate 301 has mounting grooves 303 at each of its four corners, and the inner wall of the mounting grooves 303 has a second mounting thread groove 304. Both sides of the gate plate 301 are movably connected to one side of the rubber plate 305, and the four corners of the rubber plate 305 are fixedly connected to one side of the mounting block 306. The mounting block 306 has a third mounting thread groove 307 inside, and the inner wall of the third mounting thread groove 307 is movably connected to the outer wall of the mounting screw 308. The outer wall of the mounting block 306 is movably connected to the inner wall of the mounting groove 303, and the inner wall of the second mounting thread groove 304 is threaded to the outer wall of the mounting screw 308.

[0026] Specifically: Use tools to remove the mounting screw 308, so that the mounting screw 308 is away from the inside of the second mounting thread groove 304 and the third mounting thread groove 307, so that the rubber plate 305 is released from the locked state, and then the damaged rubber plate 305 can be removed and replaced. By removing the rubber plate 305, the traditional need to replace the entire gate plate 301 is avoided, reducing the maintenance cost.

[0027] A conveying fan equipped with the aforementioned material isolation mechanism.

[0028] Specifically: The isolation frame 101 is installed on one side of the conveying fan via the flange plate 102. Before the fan needs to be shut down, the drive motor 206 is started first, which drives the rotating rod 205 to rotate under the stabilization of the stabilizing plate 204, thereby driving the threaded rod 207 to rotate. The rotation of the threaded rod 207 drives the gate plate 301 to move downward through the threaded connection between the threaded groove 302 and the threaded rod 207, so that the gate plate 301 moves from the inside of the protective shell 201 to the inside of the moving groove 103, thereby isolating the inside of the isolation frame 101.

[0029] Working principle: The isolation frame 101 is installed on one side of the conveyor fan via the flange plate 102. Before shutting down the fan, the drive motor 206 is started first, which drives the rotating rod 205 to rotate under the stabilizing plate 204. This, in turn, drives the threaded rod 207 to rotate. The rotation of the threaded rod 207 causes the gate plate 301 to move downward through the threaded connection between the threaded groove 302 and the threaded rod 207. This moves the gate plate 301 from inside the protective shell 201 to inside the moving groove 103, thereby isolating the interior of the isolation frame 101. Material backflow or dust-containing gas is prevented from entering through the gate. When the door panel 301 is impacted, it will first contact the rubber plate 305. When the device is being repaired, the mounting bolt 203 is removed with a tool to release the locking state between the protective shell 201 and the isolation frame 101. At the same time, the sealing ring 208 is moved away from the inside of the sealing groove 105. Then the disassembly mechanism 2 and the isolation plate mechanism 3 can be removed. The mounting screw 308 is removed with a tool to move the mounting screw 308 away from the inside of the second mounting thread groove 304 and the third mounting thread groove 307, so that the rubber plate 305 is released from the locking state. Then the damaged rubber plate 305 can be removed and replaced.
