[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 and Figure 3 The kinetic heat energy recovery and utilization device for a jet loom shown in the figure comprises a jet loom main frame 1 and an air collecting hopper 2 installed at the lateral air outlet position of the jet loom main frame 1, a main recovery seat 3 is fixedly mounted on the side wall of the air collecting hopper 2, a kinetic energy recovery chamber 4, an impurity recovery chamber 5 and a bottom separation chamber 6 are respectively arranged inside the main recovery seat 3 from top to bottom, a lateral flow guide pipe 7 for connecting the kinetic energy recovery chamber 4 and the impurity recovery chamber 5 is fixedly mounted on the outer surface of the main recovery seat 3, a heat conduction recovery cover 8 is installed inside the main recovery seat 3 at the periphery of the kinetic energy recovery chamber 4, the interior of the kinetic energy recovery chamber 4 is divided into an upper driving chamber with a kinetic energy recovery impeller 9 arranged inside, a middle speed-increasing chamber with a speed-increasing gear set 10 arranged inside and a lower power generation chamber with a generator 11 arranged inside by a partition, and an overhead centrifugal blade 12 is installed on the inner top surface of the impurity recovery chamber 5.

[0030] In order to cooperate with the flow diversion, a lower inlet pipe 13 is fixed to the lower end of the outer side of the heat conduction recovery cover 8, an upper return pipe 14 is fixed to the upper end of the outer side of the heat conduction recovery cover 8, and an external heat recovery pipe 15 is sleeved on the lower inlet pipe 13.

[0031] In order to improve the heat exchange efficiency, the external heat recovery pipe 15 is arranged in a spiral structure on the periphery of the lateral flow guide pipe 7.

[0032] A heat recovery pipe is connected between the upper reflux pipe 14 and the external heat recovery pipe 15. When the liquid with a lower temperature is introduced through the external heat recovery pipe 15, the temperature of the lateral guide pipe 7 is firstly heat recovered, and then introduced into the lower inlet pipe 13, and then enters the interior of the heat conduction recovery cover 8, and the air introduced into the impurity recovery chamber 5 is secondarily recovered, and finally discharged from the upper reflux pipe 14.

[0033] In order to cooperate with the fixed connection, the exhaust pipe outside the gas collecting hopper 2 is inserted into the main recovery seat 3 and fixedly connected with the kinetic energy recovery chamber 4.

[0034] In order to cooperate with the internal assembly, the kinetic energy recovery impeller 9 is movably mounted inside the upper drive chamber via a longitudinal assembly shaft 16 at the central position.

[0035] In order to increase the speed, an internal speed increasing gear set 10 includes a large gear 101 axially fixed at the lower end of the longitudinal assembly shaft 16, a side-mounted first transmission gear 102 meshing with one side of the large gear 101, a side-mounted second transmission gear 103 meshing with the side-mounted first transmission gear 102 through a horizontal axis, and a small gear 104 meshing with the side-mounted second transmission gear 103.

[0036] Working process: the exhaust gas inside the main frame 1 of the jet loom is introduced into the main recovery seat 3 from the air collecting hopper 2, and impacts the kinetic energy recovery impeller 9 located in the kinetic energy recovery chamber 4, so as to control the rotation of the kinetic energy recovery impeller 9. The kinetic energy recovery impeller 9 uses the large gear 101 to drive the side first transmission gear 102, the side second transmission gear 103 and the small gear 104 to rotate, thereby controlling the rotation of the generator 11, and then the generator 11 controls the rotation of the overhead centrifugal blades 12. The generator converts kinetic energy into electrical energy, while the overhead centrifugal blades 12 increase the internal air flow and perform solid-gas separation at the bottom.

[0037] In order to coordinate the input and output, the pinion 104 is axially sleeved on the upper input shaft of the generator 11 , and the bottom output shaft of the generator 11 is axially connected to the top-mounted centrifugal blade 12 by being inserted into the impurity recovery chamber 5 .

[0038] In order to cooperate with the lateral exhaust, a top side air guide cover communicating with the outside of the impurity recovery chamber 5 is fixedly mounted on the top surface of the impurity recovery chamber 5 and located outside the top-mounted centrifugal blades 12 .

[0039] The bottom of the top side air guide cover has a bottom air suction port with a built-in filter, and the outside is connected to the outside, so that when the top-mounted centrifugal blades 12 rotate at high speed, air will be sucked from the bottom air suction port, and then the sucked air will be discharged from the outside.

[0040] In order to cooperate with the extraction and filtration of impurities in the internal chamber of the jet loom, a horizontal lint recovery pipe 17 for connecting the inside of the jet loom main frame 1 and the impurity recovery chamber 5 is fixed on the side wall of the main recovery seat 3, and a strip dust extraction port 18 is opened on the outer side of the horizontal lint recovery pipe 17.

[0041] A water immersion sensor is installed at the bottom of the horizontal lint recovery tube 17. When liquid accumulates at the bottom, the connection between the horizontal lint recovery tube 17 and the main recovery seat 3 can be closed to prevent the internal accumulated liquid from being drawn out to the outside. An electric valve controlled by the water immersion sensor can be set at the connection end between the main recovery seat 3 and the horizontal lint recovery tube 17.

[0042] In order to facilitate the disassembly of the bottom and facilitate the subsequent cleaning and maintenance, an electrically controlled bottom lifting box 19 with a lateral opening is slidably mounted inside the bottom separation chamber 6 .

[0043] The electrically-controlled bottom lifting box 19 includes a bottom lifting box inserted into the lower opening position of the bottom separation chamber 6 and an electrically-controlled lifting support rod fixed on the outer wall of the bottom lifting box. The top of the extended end of the electrically-controlled lifting support rod is fixedly assembled with a connecting bracket on the inner top surface of the bottom separation chamber 6.

[0044] There is a cleaning port on one side of the bottom lifting box. When the lifting needs to be controlled, you only need to control the extension of the electric lifting support rod to control the bottom lifting box to descend. A pressure monitoring module can be installed on the bottom surface of the bottom lifting box. In this way, it can automatically alarm when the inside is full of accumulation, reminding people to clean the inside.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
