Description

Technical Field

[0001] This invention relates to the field of down washing and treatment technology, specifically to a down separation and recycling device and its recycling method. Background Technology

[0002] In order to separate the down from the wastewater after washing, traditional down feathers require centrifugal separation using a mesh roller to separate the down feathers and wastewater and to recycle the remaining down feathers. However, when relying on centrifugal force to separate down and water, the down is easily damaged due to excessive force, and the force generated during centrifugation can easily embed the down into the mesh, making subsequent recycling inconvenient.

[0007] Preferably, a second transmission block is installed above both ends of the material receiving and discharging cover, and a third ball screw is provided inside the second transmission block. A second bearing is installed at both ends of the third ball screw where it connects to the upper cover.

[0008] Preferably, one end of the first ball screw and the third ball screw respectively penetrates the outside of the recycling tank and the top cover, and are equipped with a gear transmission cover. A generator is installed behind the upper end of the gear transmission cover. A first gear is provided at the lower part of the inside of the gear transmission cover, and the first gear is fixedly connected to one end of the first ball screw and the third ball screw. The generator rotor penetrates and extends into the inside of the gear transmission cover, and is equipped with a second gear. The second gear meshes with the first gear for transmission.

[0009] Preferably, the diameter of the first gear is larger than that of the second gear.

[0010] Preferably, an electrically controlled water inlet valve is installed at the upper end of one side of the recycling tank, and an electrically controlled drain valve is installed at the lower end of one side of the recycling tank.

[0011] Preferably, the electric heating mechanism has multiple electric heating radiant tubes installed inside.

[0012] Preferably, the recycling bin is equipped with four support legs at the bottom corners, and the lower end of each support leg is equipped with a shock-absorbing pad, and the lower surface of the shock-absorbing pad is provided with anti-slip texture.

[0013] Preferably, a down separation and recycling method includes the following steps: Step 1: The feed connector is connected to the external material box. The blower sends the down in the material box into the receiving and discharging hood in the recycling and processing box, so that the down falls into the recycling and processing box. During the discharging process, the second servo motor on the second guide rail runs back and forth intermittently, controlling the fourth ball screw to rotate back and forth, driving the receiving and discharging hood to move back and forth along the upper cover, so as to achieve uniform distribution of down. Step 2: After the fabric is laid, connect the electric water inlet valve on the recycling tank to the water tank and pump a certain amount of clean water mixed with cleaning solution into the recycling tank so that the water level is above the dense isolation net and not higher than the water inlet of the electric water inlet valve. Soak the down in the water mixed with cleaning solution. Step 3: During the down washing process, the first servo motor on the first guide rail at the bottom of the recycling tank runs intermittently in both forward and reverse directions, controlling the second ball screw to rotate back and forth, driving the blowpipe to move back and forth along the bottom of the recycling tank. During this process, the electric three-way valve switches to the gas inlet passage, and the air pump pumps air into the blowpipe. The nozzles on the blowpipe spray the gas into the water, causing water turbulence and allowing the down to move freely in the water, thus improving the cleaning effect. Step 4: After cleaning, the wastewater is discharged by the electronically controlled drain valve. As the water level drops, the down naturally settles onto the surface of the dense isolation net in the middle of the recycling tank, thus separating the wastewater from the down. Step 5: After the wastewater is completely discharged, the first servo motor and the second servo motor run synchronously in forward and reverse intermittently. During the process, the electric heating radiation tubes in the electric heating mechanisms on both sides of the material receiving and discharging hood emit heat from top to bottom, while the electric control three-way valve switches to hot air inlet. The hot air generator continuously introduces hot air into the spray pipe, causing the recycling and processing box to generate a heat flow from bottom to top, blowing the down and thus accelerating the diffusion of moisture in the down into the air, which, together with the heat source above, accelerates the drying process. Step Six: After the down is dried, the electric heating mechanism is turned off, while the first and second servo motors continue to operate synchronously in a forward and reverse intermittent state. During this process, the blower at the feed connector reverses and switches to exhaust mode, allowing the feed hood to suck up and collect the down in the recycling bin. At the same time, the electrically controlled three-way valve switches back to the gas inlet passage, and the air pump pumps cold air into the blowpipe. The nozzles on the blowpipe blow the down onto the dense isolation net upwards, preventing the down from adhering and raising the height of the down to facilitate the feed hood's suction. This also rapidly cools the dried down for the next processing step.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes an electrically controlled drain valve to lower the water level after the down is washed, allowing the down to naturally settle onto the dense mesh surface in the middle of the recycling tank, thus separating the wastewater from the down. After the wastewater is completely discharged, the first and second servo motors within the device operate synchronously in forward and reverse rotation intermittently. During this process, the electric heating radiant tubes located on both sides of the receiving and discharging hood emit heat from top to bottom, while the electrically controlled three-way valve switches to a hot air inlet. The hot air generator continuously introduces hot air into the spray pipe, creating an upward heat flow within the recycling tank. This heat blows the down, accelerating the diffusion of moisture from the down into the air, which, combined with the heat source above, speeds up the drying process. Once the down is dried, the electric heating mechanism is turned off, while the first and second servo motors continue to operate synchronously in forward and reverse rotation. In intermittent operation, the blower at the feed inlet switches to exhaust mode, and the receiving and discharging hood sucks up and recovers the down in the recycling bin. At the same time, the electrically controlled three-way valve switches to the gas inlet passage, and the air pump pumps cold air into the blowpipe. The nozzles on the blowpipe blow the down upwards onto the dense isolation net, preventing the down from adhering and raising the height of the down to facilitate the receiving and discharging hood's suction. It also rapidly cools the dried down to facilitate the next processing step. Throughout the process, the down is not subjected to excessive force and maintains its shape well. This solves the problem of existing devices that rely on centrifugal force to separate down and water, where excessive force can easily damage the down, and the force generated during centrifugation can easily embed the down into the mesh, making subsequent recycling inconvenient.

[0015] During the washing of down feathers, the first servo motor on the first guide rail at the bottom of the recycling tank operates intermittently in both forward and reverse directions, controlling the second ball screw to rotate back and forth, driving the blowpipe to move back and forth along the bottom of the recycling tank. During this process, the electrically controlled three-way valve switches to the gas inlet passage, and the air pump pumps air into the blowpipe. The nozzle on the blowpipe sprays the gas into the water, causing water turbulence and allowing the down feathers to move freely in the water, thus improving the washing effect.

[0016] Because the device requires two sets of guide rails to reciprocate during the fabric application, washing, drying, and recycling processes, kinetic energy recovery components are installed on both sets of guide rails. When the blowpipe and the material feeding / receiving hood move with the guide rails, the first and second transmission blocks at their ends can respectively drive the first and third ball screws, causing them to rotate. This allows the first and third ball screws to mesh with the first and second gears at their ends, thus rotating the generator rotor to generate electricity. The generated electrical energy can be stored in the energy storage module to reduce the device's energy consumption. Attached Figure Description

A second guide rail 26 is installed at the middle position of the lower end of the cover 2. A fourth ball screw 32 is installed inside the second guide rail 26. A second servo motor 33 is installed at one end of the second guide rail 26.

A take-up and release cover 12 is installed at the lower end of the bracket 28. The upper end of the take-up and release cover 12 is connected to the feed connector 5 through a telescopic hose 29. The electric heating mechanism 13 is located on both sides of the material receiving and discharging hood 12.

[0020] Please see Figure 5 The other end of the blowpipe 15 is equipped with a first transmission block 17. The first transmission block 17 is equipped with a first ball screw 20. The two ends of the first ball screw 20 are rotatably connected to the inner wall of the recycling tank 1 through the first bearing 21. When the blowpipe 15 moves under the transmission action of the first guide rail 22, the first transmission block 17 at the other end can be driven by the first ball screw 20, thereby improving the stability of the blowpipe 15 during movement.

[0021] Please see Figure 1 , Figure 4 and Figure 5 A pipe winding reel 18 is installed on one side of the inner wall of the recycling and processing box 1. A spring shaft 19 is installed in the middle of the pipe winding reel 18. An electrically controlled three-way valve 6 is installed on the outer wall of the pipe winding reel 18.

[0023] Please see Figure 5 , Figure 7 and Figure 8 One end of the first ball screw 20 and the third ball screw 31 respectively penetrates the outside of the recycling box 1 and the top cover 2, and are equipped with a gear transmission cover 8.

The second gear 36 meshes with the first gear 35 for transmission. When the blow pipe 15 and the material receiving and discharging cover 12 move with the guide rail, the first transmission block 17 and the second transmission block 30 at their ends can respectively drive the first ball screw 20 and the third ball screw 31, driving the first ball screw 20 and the third ball screw 31 to rotate.

The generated electrical energy can be stored in the energy storage module to reduce the energy consumption of the device.

[0024] Please see Figure 8 The diameter of the first gear 35 is larger than that of the second gear 36, which can drive the second gear 36 to move at a faster speed and improve power generation efficiency.

[0025] Please see Figure 2 An electrically controlled water inlet valve 10 is installed at the upper end of one side of the recycling tank 1, and an electrically controlled drain valve 11 is installed at the lower end of one side of the recycling tank 1. The electrically controlled water inlet valve 10 is used to pump clean water mixed with cleaning solution into the recycling tank 1, and the electrically controlled drain valve 11 is used to discharge the wastewater after cleaning.

[0026] Please see Figure 7 The electric heating mechanism 13 has multiple electric heating radiant tubes 37 installed inside.

[0027] Please see Figure 1 Each of the four corners of the bottom of the recycling bin 1 is equipped with a support leg 3, and the bottom of the support leg 3 is equipped with a shock-absorbing pad 4, and the lower surface of the shock-absorbing pad 4 is provided with anti-slip texture.

[0028] Please see Figure 1-8 A method for separating and recycling down feathers includes the following steps: Step 1: The feed connector 5 connects to the external material box. The blower sends the down in the material box into the receiving and discharging cover 12 in the recycling and processing box 1, so that the down falls into the recycling and processing box 1. During the discharging process, the second servo motor 33 on the second guide rail 26 runs intermittently in forward and reverse directions, controlling the fourth ball screw 32 to rotate back and forth, driving the receiving and discharging cover 12 to move back and forth along the upper cover 2, so as to achieve uniform distribution of down. Step 2: After the fabric is laid, connect the electric water inlet valve 10 on the recycling tank 1 to the water tank, and pump a certain amount of clean water mixed with cleaning solution into the recycling tank 1 so that the water level is above the dense isolation net 14 and not higher than the water inlet of the electric water inlet valve 10, and immerse the down in the water mixed with cleaning solution. Step 3: During the down washing process, the first servo motor 24 on the first guide rail 22 at the bottom of the recycling tank 1 operates intermittently in both forward and reverse directions, controlling the second ball screw 23 to rotate back and forth, driving the blow pipe 15 to move back and forth along the bottom of the recycling tank 1. During the process, the electric three-way valve 6 switches to the gas inlet 601 passage, and the air pump pumps air into the blow pipe 15. The nozzle 16 on the blow pipe 15 sprays the gas into the water, causing water turbulence and allowing the down to be fully agitated in the water, thus improving the cleaning effect. Step 4: After cleaning, the wastewater is discharged by the electrically controlled drain valve 11. As the water level drops, the down naturally settles onto the surface of the dense isolation net 14 in the middle of the recycling tank 1, thus separating the wastewater from the down. Step 5: After the sewage is completely discharged, the first servo motor 24 and the second servo motor 33 operate synchronously in forward and reverse intermittently. During the process, the electric heating radiation tubes 37 in the electric heating mechanisms 13 on both sides of the material receiving and discharging hood 12 emit heat from top to bottom, while the electric control three-way valve 6 switches to the hot air inlet 602. The hot air generator continuously introduces hot air into the spray pipe 15, so that a hot flow is generated from bottom to top in the recycling and processing box 1, which blows the down and accelerates the diffusion of moisture in the down into the air, and accelerates drying in conjunction with the heat source above. Step Six: After the down is dried, the electric heating mechanism 13 is turned off, while the first servo motor 24 and the second servo motor 33 continue to operate synchronously in a forward and reverse intermittent state. During the process, the blower at the feed connector 5 reverses and switches to the exhaust state. The receiving and discharging hood 12 sucks up and recycles the down in the recycling and processing box 1. At the same time, the electric three-way valve 6 switches back to the gas inlet 601 passage, and the air pump pumps cold air into the blowpipe 15. The nozzles 16 on the blowpipe 15 blow the down on the dense isolation net 14 upwards to prevent the down from adhering and to raise the height of the down so that the receiving and discharging hood 12 can suck up the material. It also quickly cools the dried down so that it can quickly proceed to the next processing step.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
