Description

Technical Field

[0001] This invention relates to the field of air-jet loom accessories technology, and in particular to a kinetic energy and temperature recovery device for air-jet looms. Background Technology

[0002] An air-jet loom is a shuttleless loom that uses a jet of air to guide the weft yarn through the shed. Its main working principle is to use air as the weft-guiding medium, employing compressed air jets to create frictional traction on the weft yarn, thus guiding it through the shed. The jet of air achieves the purpose of weft insertion.

[0003] Currently, the high-pressure, high-temperature air generated during the operation of jet looms is not properly recycled and is directly discharged into the air, resulting in a significant waste of air temperature and kinetic energy. Moreover, the direct injection of dust into the air can seriously affect the health of operators. Summary of the Invention

[0004] The technical problem this invention aims to solve is that the high-pressure, high-temperature air generated during the operation of current jet looms is not properly recycled and utilized, but is directly discharged into the air, resulting in a significant waste of air temperature and kinetic energy. Moreover, the direct injection of dust into the air can seriously affect the health of operators.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a kinetic energy and temperature recovery device applied to an air-jet loom, including an air-jet loom body, a lateral air collection hood bolted to the outer side wall of the air-jet loom body at the air outlet position, a lateral air collection disc fixedly mounted at the air outlet position on the outer side of the lateral air collection hood, a power recovery impeller movably mounted inside the lateral air collection disc, a bottom-mounted generator cooperating with the power recovery impeller fixedly mounted on the lower surface of the lateral air collection disc, and a lateral heat energy recovery device and a self-maintenance cleaning device installed on the outer arc-shaped surface of the lateral air collection disc.

[0006] The lateral air collecting plate has a lateral assembly guide tube on its outer arc-shaped surface that matches the outer air outlet of the lateral air collecting hood. The lateral air collecting plate is fixedly connected to the lateral air collecting hood by being sleeved on the outer air outlet of the lateral air collecting hood through the lateral assembly guide tube.

[0007] The power recovery impeller includes a centrally mounted assembly tube coaxially fixed to the drive shaft at the top of the bottom-mounted generator and lateral drive blades axially fixed to the assembly tube.

[0008] The outer arc-shaped surface of the lateral gas collecting plate is provided with a first arc-shaped guide port and a second arc-shaped guide port at the connection end of the lateral heat energy recovery device and the self-maintenance cleaning device.

[0009] The lateral heat recovery device includes a metal filter screen fixed inside the first arc-shaped flow guide, a first external flow guide shroud fixed outside the metal filter screen, and a metal heat collection tube fixed on the outer surface of the metal filter screen.

[0010] The self-maintaining cleaning device includes a second external guide shroud fixedly installed at the opening position outside the second arc-shaped guide port and a lateral connecting conduit fixed on the outer surface of the second external guide shroud.

[0011] A cleaning brush that works in conjunction with a metal filter screen is installed on the leeward side of the lateral drive blade.

[0012] The internal cross-sectional size of the lateral air collection hood gradually decreases from the air jet loom body towards the lateral air collection disc.

[0013] The distance between the first arc-shaped guide orifice and the second arc-shaped guide orifice is greater than the maximum distance between the two sides of the lateral drive blade.

[0014] The beneficial effects of this invention are:

[0015] (1) The kinetic energy and temperature recovery device of the present invention applied to a jet loom uses a side air collecting hood to quickly guide the blown high-pressure air into the side air collecting plate, thereby driving the power recovery impeller used to control the bottom generator, which can greatly improve the kinetic energy recovery efficiency of high-pressure air and make it more energy-saving and environmentally friendly.

[0016] (2) A side heat recovery device is installed on the outside of the side air collection plate, which can filter the dust inside the air, improve the air quality around the equipment, and improve the working environment and respiratory health of the operators.

[0017] (3) By installing a self-maintenance cleaning device connected to the side heat recovery device on the outside of the side air collection plate, the metal filter screen is cleaned while the blades are rotated by the side drive, so as to ensure stable filtration effect and reduce the cost of later use.

[0018] (4) By installing a cleaning brush on the leeward side of the lateral drive blades, the cleaning effect on the surface of the metal filter screen can be improved.

[0019] (5) By connecting the lateral heat recovery device and the self-maintenance cleaning device, negative pressure can be generated inside the self-maintenance cleaning device, thereby improving the dust extraction effect;

[0020] (6) By fixing a metal heat collection tube on the outer surface of the metal filter, the heat energy in the air can be recovered and utilized, greatly avoiding energy waste. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Figure 1 , Figure 2 and Figure 3 The device shown is a kinetic energy and temperature recovery device for an air-jet loom, including an air-jet loom body 1. A lateral air collection hood 2 is bolted to the outer wall of the air-jet loom body 1 at the air outlet position. A lateral air collection disc 3 is fixedly installed at the air outlet position on the outer side of the lateral air collection hood 2. A power recovery impeller is movably installed inside the lateral air collection disc 3. A bottom-mounted generator 4 that cooperates with the power recovery impeller is fixedly installed on the lower surface of the lateral air collection disc 3. A lateral heat energy recovery device 5 and a self-maintaining cleaning device 6 are installed on the outer arc-shaped surface of the lateral air collection disc 3.

[0028] The bottom-mounted generator 4 is an existing technology that uses the rotation of a power recovery impeller to generate electricity, and then stores and recovers the electricity.

[0029] In order to facilitate lateral airflow, the outer arc surface of the lateral air collection plate 3 has a lateral assembly guide tube 7 that matches the outer air outlet of the lateral air collection hood 2. The lateral air collection plate 3 is fixedly connected to the lateral air collection hood 2 by being fitted onto the outer air outlet of the lateral air collection hood 2 through the lateral assembly guide tube 7.

[0030] To facilitate kinetic energy recovery, the power recovery impeller includes a centrally mounted assembly tube 8 coaxially fixed to the drive shaft at the top of the bottom-mounted generator 4 and lateral drive blades 9 axially fixed to the assembly tube 8.

[0031] To facilitate lateral exhaust and dust removal, a first arc-shaped guide port 10 and a second arc-shaped guide port 11 are provided on the outer arc-shaped surface of the lateral air collection plate 3 at the connection end between the lateral heat recovery device 5 and the self-maintaining cleaning device 6.

[0032] To facilitate heat recovery, the lateral heat recovery device 5 includes a metal filter 51 fixed inside the first arc-shaped flow guide 10, a first external flow guide shroud 52 fixed outside the metal filter 51, and a metal heat collection pipe 53 fixed on the outer surface of the metal filter 51.

[0033] The function of the metal filter 51 is to filter impurities in the air while ensuring the cleanliness of the surface of the metal heat collector tube 53, thus guaranteeing the heat exchange effect during long-term use. The metal heat collector tube 53 rapidly absorbs surface heat through the internal heat exchange fluid and then directs it to the equipment and devices that require heat energy. An external dust collection box is also installed at the air outlet on the outside of the first external guide shroud 52 to prevent dust from being discharged outwards.

[0034] To facilitate lateral dust collection, the self-maintaining cleaning device 6 includes a second external guide hood 61 fixedly installed at the outer opening position of the second arc-shaped guide port 11 and a lateral connecting conduit 62 fixed on the outer surface of the second external guide hood 61.

[0035] The lateral connecting conduit 62 is fixed to the exhaust pipe outside the first external guide shroud 52. The air introduced through the first external guide shroud 52 forms a negative pressure inside the second external guide shroud 61, thereby drawing the dust on the leeward side of the lateral drive blade 9 into the second external guide shroud 61. The negative pressure and centrifugal force work together to improve the material collection effect.

[0036] To improve the cleaning effect, a cleaning brush 12 that works in conjunction with the metal filter screen 51 is installed on the leeward side of the lateral drive blade 9.

[0037] To improve the air collection effect, the internal cross-sectional size of the side air collection hood 2 gradually decreases from the jet loom body 1 toward the side air collection disc 3.

[0038] To avoid internal air crossflow, the distance between the first arc-shaped guide port 10 and the second arc-shaped guide port 11 is greater than the maximum distance between the two sides of the lateral drive blade 9.

[0039] Operating principle: Gas is introduced from the outer outlet of the side gas collection hood 2 into the side gas collection plate 3, driving the power recovery impeller located inside the side gas collection plate 3. Then, the bottom-mounted generator 4 is controlled to generate electricity, and while driving the power recovery impeller, air is introduced from the first arc-shaped guide port 10 into the side heat energy recovery device 5. When passing through the metal filter screen 51, it is filtered, and at the same time, the heat energy is transferred to the metal heat collection tube 53. Then, while the power recovery impeller is moving, the filter material on the surface of the metal filter screen 51 is scraped off. Then, through centrifugal force, it is introduced from the second arc-shaped guide port 11 into the self-maintaining cleaning device 6. At the same time, the air inside the side heat energy recovery device 5 passes through the self-maintaining cleaning device 6 and is quickly discharged. A negative pressure is generated inside the self-maintaining cleaning device 6, thereby accelerating the removal of impurities.

[0040] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
