Description

Technical Field

[0001] This utility model relates to a down and dust separator, which is used to separate a mixture of down and dust in gas, and belongs to the technical field of down filling equipment. Background Technology

[0002] During down filling operations, some down leakage is inevitable, necessitating its collection. A common method is the fan-based dust removal system, which uses a fan to generate negative pressure and collect the scattered down, as disclosed in patent document CN203541055U, which describes an automatic dust removal system for down filling machines. However, this method collects dust along with the down. The collected down only includes the down that has fallen into the work area during operation, not the defective down intended for disposal. When the collected down is reused, the mixed dust will severely affect its quality and subsequent weighing. Therefore, it is necessary to separate the down and dust mixture. Utility Model Content

[0003] The purpose of this invention is to provide a down and dust separator that can separate down and dust from a mixed gas.

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

[0005] A lint separator includes a first chamber and a second chamber, which are separated by a partition. The partition has several mounting holes. Several filter elements are installed in the second chamber, with their tops mounted on the partition through the mounting holes. The openings of the filter elements communicate with the first chamber. A rotating blade is installed inside each filter element, with its head located in the first chamber. The air inlet pipe of the rotating blade is connected to an air source. The first chamber has an air outlet, and the second chamber has an air inlet. The second chamber also has a lint outlet and a dust outlet with valves, which are distributed vertically.

[0006] An airflow mixing down and dust enters the second chamber through the air inlet, flows through the filter element into the first chamber, where the filter element separates the down and dust. Since dust is heavier than down, it falls to the bottom. The airflow through the filter element flows from the filter element opening into the first chamber and exits through the air outlet on the first chamber. When the airflow stops and enters the second chamber through the air inlet, the down outlet valve is opened (the dust outlet valve is closed), creating negative pressure at the down outlet, expelling the separated down. The heavier dust remains in the first chamber. Then, the dust outlet valve is opened (the down outlet valve is closed), creating negative pressure at the dust outlet, expelling the remaining dust.

[0007] The air outlet is connected to a fan, which generates negative pressure to create airflow. The airflow flows in from the air inlet, passes through the second chamber, the filter element, and the first chamber, and then flows out from the air outlet.

[0008] The down outlet is connected to the inlet of the down-exiting fan, and the dust outlet is connected to the inlet of the dust-exiting fan, enabling the separate output of down and dust. Specifically, a third chamber is provided outside the down outlet and the dust outlet, and the down-exiting fan and the dust-exiting fan are housed in the third chamber. The third chamber has a down outlet and a dust outlet, with the down outlet connected to the outlet of the down-exiting fan and the dust outlet connected to the outlet of the dust-exiting fan. Since the separated down and dust are output one by one, preferably, there is only one down-exiting fan and one dust-exiting fan. The down outlet and the dust outlet are connected to the inlet of the fan via a three-way pipe, and the down outlet and the dust outlet are connected to the outlet of the fan via a three-way pipe. When collecting down, the down outlet valve is opened, the dust outlet valve is closed, and the down outlet, the fan inlet, the fan outlet, and the down outlet are connected. When collecting dust, the dust outlet valve is opened and the lint outlet valve is closed, connecting the dust outlet, fan inlet, fan outlet, and dust outlet.

[0009] Preferably, there are four filter elements.

[0010] Specifically, the valve is a cylinder-driven baffle.

[0011] Preferably, a gas storage tank is provided in the first cavity, and the air inlet pipe of the filter element is connected to the gas storage tank. The gas source can backflush the filter element through the rotating blades, blowing off down and other debris from the filter element.

[0012] Preferably, the air inlet in the second cavity is fitted with a perforated plate. To blow away and collect the down feathers on the perforated plate, a blower nozzle is provided on the underside of the perforated plate.

[0013] This invention has a simple structure, which enables the separation of down and dust in a mixed gas, and ultimately achieves the separate collection of down and dust, ensuring the quality of the collected down. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0016] like Figure 1As shown, the ash separator includes a first chamber 1, a second chamber 2, and a third chamber 3. The first chamber 1 and the second chamber 3 are separated by a partition 18, and the third chamber 3 is located on the side of the second chamber 2. The partition 18 has several mounting holes. Several (e.g., four) filter elements 4 are installed inside the second chamber 2. The top ends of the filter elements 4 are mounted on the partition 18 through the mounting holes. The openings of the filter elements 4 communicate with the first chamber 1. A rotating blade is installed inside the filter element 4, with its head located inside the first chamber 1. The air inlet pipe 7 of the rotating blade is connected to an air source. Specifically, an air storage tank 16 is installed inside the first chamber, and the air inlet pipe 7 of the rotating blade of the filter element 4 is connected to the air storage tank 16.

[0017] The first cavity 1 is provided with an air outlet 8, and the second cavity 2 is provided with an air inlet. The air outlet 8 is connected to a fan 17 through a pipe. The fan 17 generates negative pressure, creating airflow, that is, the airflow flows in from the air inlet, passes through the second cavity 2, the filter element 4, and the first cavity 1, and flows out from the air outlet 8. Inside the second cavity 2, a perforated plate 5 is installed at the air inlet. In order to blow away and collect the down on the perforated plate 5 (large-pore filter plate), a blower nozzle 6 is provided on the lower side of the perforated plate 5.

[0018] The second cavity 2 is also provided with a down outlet 9 and a dust outlet 10, which are equipped with valves (such as cylinder-driven baffles 11, 12). The down outlet 9 and the dust outlet 10 are distributed vertically. The down outlet 9 is connected to the air inlet of the down outlet fan, and the dust outlet 10 is connected to the air inlet of the dust outlet fan, so as to output the separated down and dust separately. A third cavity 3 is provided outside the down outlet 9 and the dust outlet 10. The down outlet fan and the dust outlet fan are located in the third cavity 3. The third cavity 3 is provided with a down outlet 14 and a dust outlet 15. The down outlet 14 is connected to the air outlet of the down outlet fan, and the dust outlet 15 is connected to the air outlet of the dust outlet fan. Since the separated down and dust are output one by one, the down-exit fan and the dust-exit fan are a single fan 13. The down-exit port 9 and the dust-exit port 10 are connected to the air inlet of the fan 13 through a three-way pipe, and the down-exit port 14 and the dust-exit port 15 are connected to the air outlet of the fan 13 through a three-way pipe.

[0019] In use, under the action of the fan 17, the airflow mixed with down and dust enters the second chamber 2 through the air inlet, flows through the filter element 4 to the first chamber 1, where the filter element 4 separates the down and dust. Since dust is heavier than down, the dust will fall off. The airflow through the filter element 4 flows from the opening of the filter element 4 to the first chamber 1, and flows out through the air outlet 8 on the first chamber 1.

[0020] When the fan 17 at the air outlet 8 is closed, the airflow stops and enters the second chamber 2 through the air inlet. After the fan 17 at the air outlet 8 is closed, the air tank 16 supplies airflow to the air inlet pipe 7 of the rotating blade, which can back-blown the filter element 4, blowing off the down and other particles on the filter element 4. The down outlet valve 9 is opened (the dust outlet valve 10 is closed), connecting the down outlet 9, the air inlet of the fan 13 in the third chamber 3, the air outlet of the fan 13 in the third chamber 3, and the down outlet 14. A negative pressure is generated at the down outlet 9, and the separated down is discharged. The dust, being heavier, remains in the first chamber 1. Then, the dust outlet valve 10 is opened (the down outlet valve 9 is closed), connecting the dust outlet 10, the air inlet of the fan 13 in the third chamber 3, the air outlet of the fan 13 in the third chamber 3, and the dust outlet 15. A negative pressure is generated at the dust outlet 10, and the dust is discharged.

[0021] 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.
