Description
Technical Field
The utility model relates to a III-type electric opening and closing sealing and heat-insulating device for a livestock negative-pressure fan, which can be widely applied to an installation tunnel opening of an environment-controlled negative-pressure fan of a livestock breeding shed to prevent air, rain and snow outside the shed from flowing backwards and prevent the heat in the shed from being insulated after the fan stops working.
Background
The livestock shed environment-controlled negative pressure fan is important equipment for adjusting and controlling breeding environment indexes such as temperature, harmful gas concentration and the like in the livestock shed. When the fan works, a large amount of unqualified air in the house is discharged outside the house, the air pressure in the house is reduced, negative pressure is generated outside the house relatively, and fresh air outside the house is forced to enter the house. And when the qualified air quality in the house is achieved, the fan stops working. The air inlet or the air outlet of the fan is generally provided with a device which is correspondingly opened and closed along with the starting and stopping of the fan, and when the fan is stopped, air outside the house or rain and snow can be prevented from flowing backwards from the hole of the fan to enter the house.
The current common air return prevention device comprises: a heavy hammer shutter type, a spring reset butterfly valve type and the like. The devices are passively opened by means of wind pressure formed when the fan works; after the blower is stopped, the heavy hammer or the spring is used for closing and resetting.
The shutter can be arranged at the air inlet or the air outlet of the fan, and the air pressure generated by the fan is sucked or blown. The louver blades are supported by a plurality of supports, and the existence of the blades and the supports reduces the cross-sectional area of air inlet by about 15%, so that wind resistance is formed, air flow is disturbed, and the efficiency of the fan is reduced. In addition, a large amount of blade assemblies have a large amount of fit gaps, and the air return prevention effect and the heat preservation effect are reduced. Meanwhile, the opening of the blades consumes wind energy generated by the fan and generates vibration in pulsating airflow, so that a large amount of noise is generated, and the efficiency of the fan is further reduced.
The spring reset butterfly valve is generally installed at an air outlet of the fan, the two butterfly pieces rotate around respective rotating shafts respectively, and are blown open by wind energy generated by the fan and always counterbalance the restoring force of the spring. The rotating shaft, the thickness of the butterfly sheet, the return spring and the fixing device thereof are added together, so that the air outlet area is reduced by about 8% approximately, and disturbance is generated to the air outlet. These factors all reduce the efficiency of the fan.
In view of the problems with the above-described devices, roller door solutions have subsequently emerged. The fan adopts an independent driving mode, can realize 100 percent of full opening and full closing actions, does not occupy the sectional area of an air duct, does not generate wind resistance, does not lose the efficiency of the fan, and is gradually and widely accepted and adopted at home and abroad at present. However, the curtain of the roller shutter door is formed by hinging a large number of curtain sheets, gaps exist between the adjacent curtain sheets, and the adjacent curtain sheets cannot be well sealed, so that a small amount of air leakage still exists, and the heat insulation effect is not ideal.

The device has all the advantages of the roller shutter door, simultaneously meets the requirement of gapless sealing, and has excellent sealing and heat-insulating effects.
In order to achieve the purpose, the utility model adopts the following technical scheme: a III type electric opening and closing sealing heat preservation device for a livestock negative pressure fan comprises a quilt curtain guide frame, an integral soft quilt curtain and an electric roller shutter device, wherein the electric roller shutter device is arranged above the two spaced quilt curtain guide frames, and the III type electric opening and closing sealing heat preservation device further comprises a positioning guide clamping plate and a counterweight rod;
the integral soft cotton quilt curtain is characterized in that a plurality of groups of positioning guide clamping plates are fixed on the integral soft cotton quilt curtain at intervals, guide posts on two sides of the plurality of groups of positioning guide clamping plates are respectively arranged in a U-shaped groove of a cotton quilt curtain guide frame, a balance weight rod is fixed on the bottom surface of the cotton quilt curtain guide frame, a position above the cotton quilt curtain guide frame is wound on the electric rolling curtain device, and the electric rolling curtain device drives the integral soft cotton quilt curtain to slide up and down on the two cotton quilt curtain guide frames.
The utility model has the beneficial effects that:
the device adopts an independent electric roller shutter device to open and close, does not consume wind energy generated by the fan, can be completely opened and closed, does not occupy the sectional area of the air inlet, does not generate disturbance to air inlet and air outlet airflow, does not generate noise, and can improve the efficiency of the fan. And the integral cotton quilt curtain has excellent sealing and heat-insulating properties, so that the heat loss in the house can be reduced particularly in cold winter, and the effects of heat insulation and energy conservation can be achieved. In addition, the cotton quilt has the effects of sound absorption and noise reduction, can avoid animal stress caused by noise, and provides a good breeding environment. Especially, the device plays a role in preventing backflow, preserving heat and saving energy in winter.
