Description

Technical Field

[0001] The utility model relates to the field of automated coating equipment, in particular to a detachable heat-insulated stirring fan structure in automated coating. Background Art

[0002] There is a tempering process in the automated coating process, and the entire tempering process is carried out in a closed chamber adapted to a long-distance conveyor belt.

[0003] In order to promote a relatively uniform temperature in the entire closed cavity, a fan can be used for stirring. In order to improve the energy utilization rate of the entire closed cavity, the entire closed cavity also needs a certain thickness of insulation layer. The insulation layer is generally a composite layer structure, and its internal structure is relatively soft. The fan has a large deadweight and generally needs to be fixed on the frame, but the motor that drives the fan itself cannot be placed in a high-temperature closed cavity, so how to coordinate the design of the insulation layer and the fixing method of the fan motor is still a difficult technical point. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a detachable heat-insulated stirring fan structure in automated coating. Aiming at the internal hot air flow disturbance requirement of the tempering process in automated coating, the inspection window and the fan are integrated together, which not only solves the problem of fan fixing stability, but also takes into account the sealing, heat preservation and window inspection requirements. The overall integration is high.

[0005] In order to solve the above problems, the utility model provides a detachable heat-insulated stirring fan structure in automated coating. To achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0006] The detachable heat-insulated stirring fan structure in the automated coating comprises: a fan blade, which is located in the tempering chamber; a rotating motor for air blowing, which is located outside the tempering chamber and is fixed to the fan blade through a rotating shaft for air blowing; a window hole, the outer shell of the tempering chamber comprises two layers of parallel horizontal sealing plates, the window hole penetrates the horizontal sealing plates, and the inner wall of the window hole is surrounded by a circle of channel steel sealing plate parts; a cover box, the end of the rotating motor for air blowing is also fixed with a cover box for the rotating shaft for air blowing to pass through, and the cover box and the window hole are detachably assembled; and insulation materials are filled between mutually parallel adjacent horizontal sealing plates and inside the cover box.

[0007] The beneficial effect of adopting the above technical solution is: in view of the internal airflow disturbance demand of the tempering process in the automated coating, this technical solution is to integrate the inspection window with the fan, which not only solves the problem of fan fixing, but also takes into account the sealing, heat preservation requirements and the need to open the window for inspection from time to time. The overall integration is high and the design is ingenious.

[0008] The fan blades inside can disturb the hot air flow, and the motor outside can prevent the motor from working at an extremely high temperature.

[0009] The space surrounded by the cover box itself is convenient for filling with thermal insulation materials to reduce heat loss.

[0010] The channel steel cover plate not only strengthens the structural strength of the window hole to facilitate the load-bearing of the rotating motor for the blower, but also plays the role of wrapping and protecting the thermal insulation layer between the two parallel horizontal cover plates.

[0011] As a further improvement of the utility model, the air-blowing rotating motor, the air-blowing rotating shaft, and the fan blades are coaxially fixed to each other.

[0012] The beneficial effect of adopting the above technical solution is: achieving a centrifugal blowing effect.

[0013] As a further improvement of the present invention, one side of the cover box includes a window cover plate, the window cover plate has an extended convex edge, the extended convex edge is in contact with the outer wall of the horizontal sealing plate, and the area of ​​the window cover plate is larger than the area of ​​the window hole.

[0014] The beneficial effect of adopting the above technical solution is: the larger-sized window cover ensures that the window opening can be covered, and at the same time plays the role of a stop limiter to prevent the cover box from falling into the tempering line.

[0015] As a further improvement of the present invention, the edge of the extended convex edge also has a lower folded edge extending axially toward the position of the fan blade.

[0016] The beneficial effect of adopting the above technical solution is that the lower folding edge improves the bending strength of the structure here.

[0017] As a further improvement of the present invention, the edge of the channel steel type sealing plate member itself has an outward-turned folded edge extending in a direction away from the centroid of the window hole itself, and the outward-turned folded edge is fixed to the horizontal sealing plate in surface contact.

[0018] The beneficial effects of adopting the above technical solution are: the outward folded edge not only improves the structural strength, but also improves the sealing assembly relationship between the channel steel type sealing plate and the horizontal sealing plate.

[0019] As a further improvement of the utility model, the outwardly turned folded edge and the outwardly extended convex edge are provided with mutually coaxial screw through holes.

[0020] The beneficial effect of adopting the above technical solution is that it is easy to use screws to achieve sealing and fixing for a long time.

[0021] As a further improvement of the present invention, the axial thickness of the cover box is shorter than the penetration length of the window hole, and the penetration length of the window hole is shorter than the axial length of the rotating shaft for blowing.

[0022] The beneficial effect of adopting the above technical solution is: ensuring that the fan blades maintain a certain distance from the inner wall of the tempering line, so as to facilitate the disturbance of the airflow.

[0023] As a further improvement of the utility model, the thermal conductivity of the heat-insulating material in the cover box is smaller than the thermal conductivity of the heat-insulating material between the parallel horizontal sealing plates.

[0024] The beneficial effect of adopting the above technical solution is: since the inherent design of the window hole will inevitably lead to a worse airtightness effect compared to the case where there is no opening, better insulation materials are used to compensate for it.

[0035] The beneficial effect of adopting the above technical solution is: in view of the internal airflow disturbance requirements of the tempering process in automated coating, this technical solution is to integrate the inspection window with the fan, which not only solves the problem of fixing the fan, but also takes into account the sealing, insulation requirements and the need to open the window for inspection from time to time. The overall integration is high and the design is ingenious. The fan blades inside can disturb the hot air flow, and the motor outside can prevent the motor from working at ultra-high temperatures. The space surrounded by the cover box itself is convenient for filling with insulation materials to reduce heat loss. The channel steel sealing plate not only strengthens the structural strength of the window hole, making it easier to bear the load of the rotating motor for air blowing, but also wraps and protects the insulation layer between the two parallel horizontal sealing plates.

[0036] In other embodiments of the present invention, the air-blowing rotating motor 30 , the air-blowing rotating shaft 33 , and the fan blades are coaxially fixed to each other.

[0037] The beneficial effect of adopting the above technical solution is: achieving a centrifugal blowing effect.

[0041] The beneficial effect of adopting the above technical solution is that the lower folding edge improves the bending strength of the structure here.

[0042] like Figure 4As shown, in other embodiments of the present invention, the edge of the channel steel sealing plate 37 has an outward folded edge 3700 extending away from the centroid of the window hole 36, and the outward folded edge 3700 is fixed to the horizontal sealing plate 32 in surface contact.

[0043] The beneficial effects of adopting the above technical solution are: the outward folded edge not only improves the structural strength, but also improves the sealing assembly relationship between the channel steel type sealing plate and the horizontal sealing plate.

[0044] In other embodiments of the present invention, the outwardly turned folded edge 3700 and the outwardly extended convex edge 3100 are provided with coaxial screw through holes 38 .

[0045] The beneficial effect of adopting the above technical solution is that it is easy to use screws to achieve sealing and fixing for a long time.

[0046] In some other embodiments of the present invention, the axial thickness of the cover box 35 is shorter than the penetration length of the window hole 36 , and the penetration length of the window hole 36 is shorter than the axial length of the air-blowing rotating shaft 33 .
