Description

Technical Field

[0001] This invention relates to the field of fluidized bed freezers, and is particularly applicable to a fan removal structure for a fluidized bed freezer. Background Technology

[0002] Fluidized bed freezers are used for rapidly freezing small-particle foods. The freezer contains a centrifugal fan, conveyor belt, evaporator, etc. The fan blows air onto the evaporator fins; the cooled air, after heat exchange in the evaporator, is then blown onto the food to lower its temperature. Fluidized bed freezers have a compact structure and operate at low temperatures and high humidity (typically around -35℃ and 98% humidity). The fan motor requires frequent maintenance.

[0003] The fan housing is compact, forcing maintenance personnel to crouch down to disassemble and reassemble the motor inside. It requires at least two people to move the motor, but the cramped housing is almost completely crammed with two people, making fan maintenance extremely inconvenient. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a fan removal structure for a fluidized bed freezer.

[0005] To achieve the above-mentioned objectives, the present invention provides a fan removal structure for a fluidized bed freezer, comprising a moving track, a connecting structure disposed on the moving track, and a fan disposed on the connecting structure. The connecting structure is detachably connected to the moving track, and the moving track is disposed on the fan cavity of the fluidized bed freezer.

[0006] The surface of the connecting structure that contacts the moving track includes a first end and a second end. A movable component is provided on the connecting structure. The movable component is located on the side of the first end away from the second end. The center of gravity of the fan is located on the side of the first end closer to the movable component.

[0007] More specifically, the center of gravity of the fan is located between the first end and the moving part.

[0008] More specifically, the center of gravity of the fan is located on the side of the moving part away from the first end.

[0009] More specifically, a connecting plate is rotatably provided on the movable structure. One end of the connecting plate is connected to a roller, and the other end is provided with a moving rod. The moving rod contacts the movable structure during movement.

[0010] More specifically, the connection structure includes a perforated plate connected to the moving track and a fan fixing rod connected to the perforated plate. The fan is mounted on the fan fixing rod, and the perforated plate is detachably connected to the moving track.

[0011] More specifically, a limiting rod is provided on the connecting structure, and the limiting rod is located on the side of the moving track away from the fan cavity.

[0012] More specifically, the distance between the first end and the center of the moving part is 10-40cm.

[0013] More specifically, the movable component is configured as a roller, which is located on the side near the outlet.

[0014] More specifically, a tie rod is provided on the fan, and the tie rod is located on the side near the outlet.

[0015] More specifically, the tie rod is equipped with a quick-release structure that facilitates rapid assembly and disassembly with the fan.

[0016] This invention mainly designs a fan removal structure for a fluidized bed freezer, setting up a moving track and a moving component to facilitate pulling the fan out of the fan cavity, making it convenient for maintenance personnel to perform maintenance. A connecting structure is set up to facilitate the fixing of the fan during normal use. By setting the fan and the moving component on the same side of the connecting structure, after the connecting structure is released from the moving track, because the fan is set on one side, due to the center of gravity, the fan will flip towards the side closer to the moving component. The connecting structure will disengage from the moving track, and the moving component will contact the moving track. By applying a pulling force, the fan, under the action of the moving component, moves out of the fan cavity along the connecting track. Attached Figure Description

[0029] It should be understood that the accompanying drawings are for illustrative purposes only.

[0030] A fan 2 removal structure for a fluidized bed freezer, such as Figures 1-8 As shown, it includes a moving track 3, a connecting structure disposed on the moving track 3, and a fan 2 disposed on the connecting structure.

[0031] The moving track 3 is installed on the fan cavity 1 of the fluidized bed freezer. The moving track 3 is positioned along the depth direction of the fan cavity 1, allowing the fan 2 to enter or exit the fan cavity 1 along the moving track 3. Because the moving track 3 needs to support the fan 2 and the connecting structure, it requires sufficient strength; therefore, the moving track 3 needs a certain thickness to ensure its strength. Furthermore, reinforcing ribs can be provided on the moving track 3 to increase its strength. To ensure the stability of the fan 2 during movement, moving tracks 3 are provided on both sides of the fan cavity 1, and the width of the moving track 3 matches the connecting structure. A first connecting hole is provided on the moving track 3 for connection with the connecting structure.

[0032] The connecting structure is detachably connected to the moving track 3. The connecting structure includes a perforated plate 41 connected to the moving track 3 and a fan fixing rod 42 connected to the perforated plate 41. The fan 2 is mounted on the fan fixing rod 42. Perforated plates 41 are provided at both ends of the fan fixing rod 42 for connecting to the moving tracks 3 on both sides. Furthermore, the perforated plate 41 is detachably connected to the moving track 3.

[0033] A second connecting hole is provided on the perforated plate 41, and a connector is provided in the second connecting hole. The connector passes through the second connecting hole and the first connecting hole, connecting the perforated plate 41 to the moving track 3. Furthermore, the connector is a bolt. After the perforated plate 41 is connected to the moving track 3, the position of the fan 2 is fixed, and it can work normally without displacement or other problems. When the connection is released, the fan 2 can enter or exit the fan cavity 1 along the moving track 3.

[0034] The perforated plate 41 includes a fixed connecting plate 411 and a track connecting plate 412. The fixed connecting plate 411 is connected to the fan fixing rod 42, and the track connecting plate 412 is connected to the moving track 3. Furthermore, the second connecting hole is provided on the track connecting plate 412. The fixed connecting plate 411 and the track connecting plate 412 are connected at an angle. Furthermore, the fixed connecting plate 411 and the track connecting plate 412 are arranged perpendicularly, and there is an arc transition between the fixed connecting plate 411 and the track connecting plate 412. The perforated plate 41 is integrally formed.

[0035] During the process of pushing and moving the fan 2, the connecting structure may fall off the moving track 3. Therefore, a limit rod 43 is provided on the connecting structure, and the moving track 3 is located between the limit rod 43 and the fan cavity 1 to ensure that the connecting structure moves along the set route and will not fall off. Of course, the moving track 3 can also be set as a U-shaped structure, and the track connecting plate 412 is set in the groove of the U-shaped moving track 3 to limit the movement of the connecting structure and prevent it from falling off.

[0036] After the connecting structure is disconnected, the fan 2 needs to be moved. To reduce friction with the moving track 3, a moving part is provided on the connecting structure. The moving part can drive the fan 2 to move on the moving track 3. Furthermore, the moving part can be a structure with low friction, such as a roller, ball, or slider. In this solution, the moving part is set as a roller 5. When the connecting structure is bolted to the moving track 3, the roller 5 does not need to contact the moving track 3. After the connecting structure is disconnected from the moving track 3, the roller 5 contacts the moving track 3.

[0037] The track connecting plate 412 includes a first end and a second end. The movable component is located on the side of the first end away from the second end. Further, the movable component can be located between the first end and the fan. The center of gravity of the fan is located on the side of the first end closer to the movable component. In this case, after the connecting structure is disconnected from the moving track 3, the fan 2 rotates until the fan 2 is stable. The support point of the fan 2 on the moving track 3 is the movable component and the first end. Alternatively, the movable component can be located on the side of the movable component away from the first end. In this case, after the connecting structure is disconnected from the moving track 3, the fan 2 rotates until the fan 2 is stable. The support point of the fan 2 on the moving track 3 is the movable component.

[0038] The distance between the first end and the center of the roller is set to 10-40cm.

[0039] The movable component can be located on the side closer to the outlet or on the side farther from the outlet, but in order to facilitate the removal of the fan 2 from the fan cavity 1, the movable component is located on the side closer to the outlet.

[0040] A rotatable connecting plate 61 is provided on the movable structure. One end of the connecting plate 61 is connected to a roller 5, and the other end is provided with a moving rod 62. The connecting plate 61 is connected to a fixed connecting plate 411 by bolts. The bolt connection point is the connection point, and the connection point of the connecting plate 61 is located between the roller 5 and the moving rod 62. The moving rod 62 contacts the connecting structure during movement. Furthermore, the moving rod 62 is set as a screw, and a threaded sleeve is provided on the connecting plate 61. The moving rod 62 is located in the threaded sleeve and can move up and down within the threaded sleeve.

[0041] Because the connecting plate 61 is rotatable, when the connecting structure is connected to the moving track 3, the moving rod 62 moves away from the track connecting plate 412, leaving a gap between the moving rod 62 and the track connecting plate 412. At this time, the side of the connecting plate 61 with the moving rod 62 can rotate towards the track connecting plate 412. At the same time, the moving part gradually moves away from the moving track 3, and the side of the connecting plate 61 with the moving rod 62 gradually moves closer to the track connecting plate 412. When the connecting structure needs to be disconnected from the moving track 3, the connecting plate 61 is kept as parallel to the moving track 3 as possible. The moving rod 62 moves towards the track connecting plate 412 within the threaded sleeve until it abuts against the track connecting plate 412. At this time, the roller 5 also contacts the moving track 3. The connecting parts of the moving track 3 and the connecting structure are removed, and the moving rod 62 is rotated in the opposite direction, causing the moving rod 62 to move away from the track connecting plate 412 within the threaded sleeve. The connecting structure is then disconnected from the moving track 3.

[0042] To facilitate the pulling out of the fan 2, a pull rod 21 is provided on the fan 2. Furthermore, the pull rod 21 is located on the side near the outlet. After the connecting structure is disconnected from the moving track 3, pressing the pull rod 21 causes the fan 2 to rotate again in its rotation direction, completely disengaging the connecting structure from the moving track 3. The moving part then contacts the moving track 3, and pulling the pull rod 21 at this point allows the fan 2 to be pulled out easily and effortlessly.

[0043] When the fan 2 is working normally, the tie rod 21 is detachable and does not affect the operation of the air duct. When maintenance of the fan 2 is required, the tie rod 21 is reconnected to the fan 2. For easy disassembly and assembly, the tie rod 21 is provided with a quick-disassembly and assembly structure to facilitate quick connection and disconnection from the fan 2. Of course, the tie rod 21 can also be designed as a foldable structure, eliminating the need to disassemble the tie rod 21.

[0044] Example 1: When the center of gravity of the fan is set between the first end of the track connecting plate and the roller;

[0045] When the fan 2 is in normal working condition, the connecting structure is bolted to the moving track 3, and the fan 2 operates normally. The end of the moving rod 62 near the track connecting plate 412 does not extend out of the threaded sleeve, and there is a gap between it and the track connecting plate 412. The connecting plate 61 is loose and rotatable. The side of the connecting plate 61 where the moving rod 62 is located is positioned close to the track connecting plate 412, so that the roller 5 is away from the moving track 3 and does not contact the moving track 3.

[0046] When it is necessary to disassemble the fan 2, first rotate the moving rod 62 on the connecting plate 61 until it abuts against the track connecting plate 412. At this time, the roller 5 on the other side of the connecting plate 61 is also in close contact with the moving track 3. Then, remove the connector on the track connecting plate 412. Since the fan 2 is supported by the connecting structure and the roller 5, it is relatively easy to remove the connector, and the fan 2 will not shift as the connector loosens. After the connectors on the track connecting plate 412 are disassembled, the moving rod 62 is rotated in the opposite direction, causing the moving rod 62 to move away from the track connecting plate 412. The connecting structure is gradually relieved of the pressure applied by the moving rod 62 towards the moving track 3, and the center of gravity of the fan 2 is set between the roller 5 and the first end of the track connecting plate 412, causing the fan 2 and the connecting structure to rotate around the first end of the track connecting plate 412. One end of the perforated plate 41 of the connecting structure will be tilted up, and the entire fan 2 is supported only by one end of the perforated plate 41 and the roller 5. At this time, the center of gravity of the fan and the center of the roller are on the same straight line. With a small force, the pull rod 21 can be pressed to tilt the fan 2 up with the roller 5 as the fulcrum, so that one support point of the connecting structure leaves the moving track 3. At this point, the entire fan 2 is only supported by the roller 5, and the fan 2 can be easily pulled out of the housing.

[0047] After the fan 2 is disassembled and maintained, push the fan 2 into the housing in the same way. After reaching the installation position, release the pull rod 21 and rotate the moving rod 62 so that the moving rod 62 moves towards the track connecting plate 412 and abuts against the perforated plate 41 until the entire mounting surface of the track connecting plate 412 of the perforated plate 41 is in contact with the moving track 3. Then the connector can be installed to fix the fan 2.

[0048] Example 2: When the center of gravity of the fan is set on the side of the roller away from the first end of the track connecting plate;

[0049] When the fan 2 is in normal working condition, the connecting structure is bolted to the moving track 3, and the fan 2 operates normally. The end of the moving rod 62 near the track connecting plate 412 does not extend out of the threaded sleeve, and there is a gap between it and the track connecting plate 412. The connecting plate 61 is loose and rotatable. The side of the connecting plate 61 where the moving rod 62 is located is positioned close to the track connecting plate 412, so that the roller 5 is away from the moving track 3.

[0050] When it is necessary to disassemble the fan 2, first rotate the moving rod 62 on the connecting plate 61 until it abuts against the track connecting plate 412. At this time, the roller 5 on the other side of the connecting plate 61 is also in close contact with the moving track 3. Then, an upward supporting force is applied to the pull rod 21. Because the center of gravity of the fan 2 is set on the side of the roller 5 away from the first end of the track connecting plate 412, the fan 2 will immediately rotate when the connecting parts on the connecting structure are removed. If there is no upward supporting force on the fan 2, the fan 2 will rotate, and the second connecting hole on the perforated plate 41 and the first connecting hole on the moving track 3 will be misaligned, causing the connecting parts to get stuck and unable to be removed. After the connecting parts on the connecting structure are disassembled, the supporting force applied to the pull rod 21 is removed. Since the center of gravity of the fan 2 is set on the first end of the roller away from the track connecting plate, the connecting structure will rotate. At this time, the fan 2 and the connecting structure rotate around the roller as the axis until the center of gravity of the fan 2 and the center of the roller 5 are on the same vertical plane. The perforated plate 41 of the connecting structure will move away from the moving track 3 as a whole. The entire fan 2 is only supported by the roller 5. At this time, the fan 2 can be easily pulled out of the housing by pulling the pull rod 21 with a very small force.

[0051] After the fan 2 is disassembled and maintained, push the fan 2 into the housing in the same way. After reaching the installation position, lift the pull rod 21 with a small force so that the connecting structure rotates in the direction of the moving track with the roller 5 as the fulcrum until the track connecting plate contacts the moving track. At this time, if only the first end of the track connecting plate contacts the moving track, rotate the moving rod 62 so that the moving rod 62 moves towards the track connecting plate 412 and abuts against the perforated plate 41 until the entire mounting surface of the track connecting plate 412 of the perforated plate 41 is in contact with the moving track 3. Then the connector can be installed to fix the fan 2. If the entire mounting surface of the track connecting plate is in contact with the moving track, the connector can be installed directly to fix the fan 2.

[0052] Regardless of whether the center of gravity of the fan 2 is set between the first end of the track connecting plate 412 and the roller 5, or on the side of the roller 5 away from the first end of the track connecting plate 412, the closer the center of gravity of the fan 2 is to the roller 5, the less effort it takes for the staff to pull out the fan 2. Of course, after the fan 2 rotates, the center of gravity of the fan 2 and the center of the roller 5 are on the same straight line.

[0053] This invention mainly designs a fan removal structure for a fluidized bed freezer. It includes a moving track 3 and a moving component to facilitate pulling the fan 2 out of the fan cavity 1, making maintenance easier. A connecting structure is provided to secure the fan 2 during normal use. By setting the center of gravity of the fan 2 near the roller 5 at the first end, after the connecting structure is released from the moving track 3, the fan 2 rotates due to the center of gravity, causing the connecting structure to disengage from the moving track 3. At this point, the roller 5 contacts the moving track 3, and by applying a pulling force, the fan 2 moves along the moving track 3 out of the fan cavity 1 under the action of the roller 5. A pull rod 21 is also provided to facilitate pulling the fan 2 out of the fan cavity 1.
