Description

Technical Field

[0001] This utility model relates to an underground down-collecting unit and an underground down-collecting system composed of the underground down-collecting unit, used to collect down (and dust) from the environment, belonging to the technical field of down filling equipment. Background Technology

[0002] During down filling, whether done manually or automatically, some down leakage is inevitable. To collect this leakage and prevent environmental pollution and down waste, down filling sites often use negative pressure fans for dust collection. For example, patent document CN203541055U discloses a dust collection system for an automatic down filling machine. This system includes a dust collection box with an inlet, an outlet, and a blower. The inner end of the inlet is connected to the blower's suction port, the inner end of the outlet is connected to the blower's exhaust port, and the outer end of the outlet is connected to a collection bag. It also includes a down filling workbench with collection holes on its surface and a collection hopper below the holes. The outlet of the collection hopper is connected to the outer end of the dust collection box inlet. This dust collection system can collect down on the workbench; however, down is lightweight, and even slight airflow can cause it to fly off the workbench, rendering the system unable to collect it. In other words, once down falls outside the workbench, the system is ineffective; for example, if down drifts onto the ground in the down filling area, the system cannot collect it. Furthermore, dust removal systems are ineffective against dust in down-filled areas. Utility Model Content

[0003] The purpose of this invention is to provide an underground down-collecting unit and an underground down-collecting system composed of the underground down-collecting unit, so as to effectively collect down and dust from the down-filling site.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] The underground lint-absorbing unit includes a floor with perforations, the floor is mounted on a support, an air duct is provided under the floor, a collection hopper is provided between the floor and the air duct, and the bottom of the collection hopper is connected to the air duct.

[0006] To provide more stable support for the floor, the bracket is equipped with a horizontal support frame, and the floor is mounted on the bracket via the horizontal support frame.

[0007] An underground down suction system includes several underground down suction units. Each underground down suction unit includes a floor with perforations. The floor is mounted on a support frame, and an air duct is installed under the floor. A collection hopper is installed between the floor and the air duct. The collection hopper has an upper opening and a bottom collection port. The upper opening of the collection hopper collects items (i.e., leaked down and dust) from the floor perforations, and the bottom collection port of the collection hopper is connected to the air duct. Several underground down suction units are divided into one or more subsystems. In one subsystem, the air ducts of adjacent underground down suction units are connected together. The air duct is connected to a fan, creating negative pressure within the air duct.

[0008] When in use, the fan creates negative pressure in the air duct. Down that leaks out from the floor or the filling space enters the collection hopper through the floor holes, then enters the air duct through the collection port of the collection hopper, and is collected in one place through the air duct.

[0009] To control one or more sections of the underground lint-collecting unit, an airflow control component is installed between the air ducts of adjacent underground lint-collecting units. Specifically, preferably, the airflow control component has rotating blades, which rotate to control the airflow path of the duct.

[0010] In order to separate down and dust in the air duct, the air duct is connected to a down and dust separation device.

[0011] Specifically, the underground down-collecting system is located in an enclosed space (such as a down-filling room), which has a fresh air system to balance the pressure within the enclosed space and ensure the dust removal effect.

[0012] This invention enables dust removal (including down, dust, etc.) of the entire down filling area, effectively collects down that has leaked out of the filling area, and reduces material waste after recycling. At the same time, it can effectively remove dust and clean the down filling environment. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] Fig. 1 This is a schematic diagram of an underground down-absorbing system.

[0015] Fig. 2 This is an exploded view of the components of the underground down-absorbing system.

[0016] Fig. 3 This is a schematic diagram of the airflow control component. Detailed Implementation

[0017] like Figs. 1-3As shown, the underground down-absorbing system is distributed within the down-filling workshop (or other down-filling area) and includes several underground down-absorbing units 1, which are laid across the floor of the down-filling workshop. Each underground down-absorbing unit 1 includes a floor 3 (replacing the ground surface), the floor 3 having perforations 4, and the floor 3 mounted on a support 5. To further stabilize the floor 3, a horizontal support frame 6 is provided on the support 5, and the floor 3 is mounted on the support 5 via the horizontal support frame 6. An air duct 9 is located beneath the floor 3, and a collection hopper 7 is positioned between the floor 3 and the air duct 9. The collection hopper 7 has an upper opening and a bottom collection port 8. The upper opening of the collection hopper 7 collects items from the perforations 4 of the floor 3, and the bottom collection port 8 of the collection hopper 7 connects to the air duct 9.

[0018] For the entire underground lint-absorbing system, several underground lint-absorbing units 1 can be integrated as a whole, with the air ducts 9 of adjacent units connected together. Each air duct 9 is connected to a fan, creating negative pressure within it. This configuration places certain demands on the fan's power, and the bends in the air ducts 9 also increase resistance. Alternatively, the underground lint-absorbing units 1 can be divided into multiple (two or more) subsystems. Within each subsystem, the air ducts 9 of adjacent units are connected together, with each air duct 9 connected to a fan, creating negative pressure within it. This design reduces resistance and lessens the workload on the fans. In this case, one fan can be connected to multiple unconnected air ducts 9 (without reducing fan workload), or multiple fans corresponding to the number of subsystems can be used.

[0019] To control one or more sections of the underground lint-collecting unit, an airflow control component 2 is installed between the air ducts 9 of adjacent underground lint-collecting units 1. Specifically, as shown... Fig. 3 As shown, the air passage on / off control component 2 has a rotating blade 10, which is mounted on a rotating shaft 11. The rotating shaft 11 is connected to a cylinder 13 via a connecting rod 12. The cylinder drives the rotating blade 10 to rotate, thus the rotation of the rotating blade 10 controls the air passage on / off of the air passage 9.

[0020] The underground down-collecting system can be installed in an enclosed space (such as an enclosed down-filling room) with a fresh air system to balance the pressure within the enclosed space, ensure the dust removal effect, and also deliver fresh air.

[0021] During operation, a negative pressure is generated within the air duct 9 by the fan, causing air in the filling area to flow from the high-pressure area to the low-pressure area, creating airflow. Down leaking from the floor or filling space enters the collection hopper 7 through the perforations 4 in the floor 3, and then enters the air duct 9 through the collection port 8 of the collection hopper 7, where it is collected in one location. The collected air contains both down and dust, which can be separated within the air duct 9. At this point, the air duct 9 can be connected to a down and dust separation device, which separates the down and dust contained in the collected air. The collected down can be reused, and the collected dust purifies the filling environment.

[0022] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
