Description

Technical Field

[0001] This invention relates to the field of exhaust gas treatment technology for air-jet looms, and in particular to an exhaust gas inlet pressurization and regulation 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. Air is used as the weft-guiding medium; the compressed air jet creates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion.

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

[0004] The technical problem that this invention aims to solve is that the current waste gas is not properly recycled and utilized, and is directly discharged into the air, resulting in a significant waste of kinetic energy. Moreover, the dust and debris in the air will be directly sprayed into the air, which will seriously affect the health of the operators.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a gas outlet pressure regulating device for an air jet loom, including a main frame, wherein a height-adjustable gas guide hood is installed at the gas outlet position of the main frame, an electrically controlled lifting guide machine is installed inside the gas guide hood, and a bottom cleaning cover with a downward protrusion is provided on the bottom surface of the gas guide hood, wherein an electrically controlled centrifugal cleaning brush is movably installed inside the bottom cleaning cover.

[0006] An embedded guide rail is fixedly mounted on the inner wall of the main frame, and an electrically controlled lifting screw for controlling the raising and lowering of the exhaust gas guide hood is movably mounted inside the embedded guide rail.

[0007] The exhaust gas guide hood is assembled with the electrically controlled lifting screw by means of internally threaded lifting blocks on both outer walls.

[0008] The electrically controlled lifting guide includes a bottom lift fixed to the outer wall of the exhaust gas guide hood, an inner cover fixed to the upper protruding end of the bottom lift, a centrifugal separator installed inside the inner cover, and an annular metal filter cover fixed at the lower air inlet position of the centrifugal separator.

[0009] The inner casing sidewall has an arc-shaped flow guide.

[0010] The electrically controlled centrifugal cleaning brush includes a bottom adjustment plate disposed inside the bottom cleaning cover, an upper mounting base fixed to the upper end of the bottom adjustment plate, a cleaning brush mounted on the upper end of the upper mounting base, and a bottom drive motor fixedly hung at the lower end of the bottom cleaning cover.

[0011] A lateral slag collection box is fixedly mounted on the side wall of the bottom cleaning hood via a lateral guide pipe.

[0012] A top-mounted pressure sensor module for monitoring internal wind pressure is fixedly mounted on the upper surface of the inner casing.

[0013] An embedded electronically controlled exhaust hood is movably mounted on the inner side of the exhaust gas guide hood.

[0014] The embedded electronically controlled exhaust hood includes an arc-shaped first adjustment hood and an arc-shaped second adjustment hood that are slidably mounted on the inner side of the exhaust hood at the exhaust outlet position, and a first control motor and a second control motor that are fixed on the upper end of the exhaust hood.

[0015] The beneficial effects of this invention are: (1) The exhaust gas inlet pressure regulating device of the present invention applied to the air jet loom automatically controls the air pressure according to the angle of the internal air pressure, thereby reducing energy consumption; (2) By using a height-adjustable exhaust gas guide hood at the exhaust port position of the main frame, the exhaust gas of the jet loom can be guided and recycled, reducing resource waste and improving the external environment; (3) By adjusting the height of the exhaust gas guide hood through internal and external lifting methods, and by installing an electrically controlled lifting guide machine inside the exhaust gas guide hood, the air introduced into the exhaust gas guide hood can be pressurized twice before being injected, thereby increasing the pressure of the secondary injection and ensuring the utilization effect. (4) An electrically controlled centrifugal cleaning brush is installed inside the bottom cleaning cover. It can automatically clean the surface of the annular metal filter cover of the air inlet when idle, so as to prevent impurities in the exhaust gas from drifting into the air, improve safety and reduce the cost of later use. (5) The self-maintaining structural design can reduce the difficulty of later maintenance; (6) The external slag removal mechanism is designed for easier cleaning; (7) The angle and volume of the air outlet can be adjusted as needed, greatly improving its applicability.

[0020] 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.

[0021] 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.

[0022] Figure 1 , Figure 2 and Figure 3 The exhaust gas inlet pressurization and regulation device shown includes a main frame 1. The exhaust gas inlet position of the main frame 1 is equipped with a height-adjustable exhaust gas guide hood 2. An electrically controlled lifting guide machine is installed inside the exhaust gas guide hood 2. The bottom surface of the exhaust gas guide hood 2 has a downwardly protruding bottom cleaning cover 4. An electrically controlled centrifugal cleaning brush is movably installed inside the bottom cleaning cover 4.

[0023] Working principle: Exhaust gas is introduced through the air inlet of exhaust gas guide hood 2, and then the electric lifting guide machine is raised or lowered according to the actual pressure of the exhaust gas. The electric lifting guide machine is then used for secondary pressurization, and the pressurized and filtered air is discharged from the air outlet of exhaust gas guide hood 2.

[0024] To facilitate internal guidance, an embedded guide rail 6 is fixedly mounted on the inner wall of the main frame 1. An electrically controlled lifting screw 7 for controlling the raising and lowering of the exhaust gas guide hood 2 is movably mounted inside the embedded guide rail 6.

[0025] To facilitate lifting and adjusting, the exhaust gas guide hood 2 is threaded onto the electrically controlled lifting screw 7 via internally threaded lifting blocks on both outer walls.

[0026] To facilitate the electric lifting adjustment, the electric lifting guide includes a bottom lifter 31 fixed on the outer wall of the exhaust gas guide hood 2, an inner cover 32 fixed on the upper protruding end of the bottom lifter 31, a centrifugal separator 33 installed in the inner cover 32, and an annular metal filter cover 34 fixed at the lower air inlet position of the centrifugal separator 33.

[0027] The bottom lifting platform 31 adjusts the height of the inner cover 32 inside the exhaust gas guide hood 2 by telescopic control, thereby changing the internal height and recycling the sinking exhaust gas for secondary pressurization.

[0028] To reduce wind resistance and improve internal airflow, the inner casing 32 has an arc-shaped airflow shield 35 on its side wall.

[0029] To facilitate bottom cleaning, the electrically controlled centrifugal cleaning brush includes a bottom adjustment plate 51 located inside the bottom cleaning cover 4, an upper mounting base 52 fixed to the upper end of the bottom adjustment plate 51, a cleaning brush 53 mounted on the upper end of the upper mounting base 52, and a bottom drive motor 54 fixedly hung at the lower end of the bottom cleaning cover 4.

[0030] To facilitate lateral slag collection, a lateral slag collection box 9 is fixedly installed on the side wall of the bottom cleaning cover 4 via a lateral feed pipe 8.

[0031] The bottom drive motor 54 drives the bottom adjustment plate 51 to rotate, and then the bottom adjustment plate 51 drives the cleaning brush 53 at the upper end of the upper mounting base 52 to rotate slowly to clean the surface of the annular metal filter cover 34. Then, through high-speed rotation, the cleaned impurities are guided into the side slag collection box 9 through the side guide pipe 8.

[0032] In order to control the angle and magnitude of the internal wind pressure, a top-mounted pressure sensor module 10 for monitoring the internal wind pressure is fixedly mounted on the upper surface of the inner cover 32.

[0033] When the pressure of the top pressure sensor module 10 is low, it means that the exhaust gas pressure is sufficient and can be directly discharged from the air inlet of the exhaust gas guide hood 2 to the air outlet. When the pressure of the top pressure sensor module 10 is high, it means that the exhaust gas pressure is insufficient and the exhaust gas falls on the inner cover 32 at a downward angle. At this time, the bottom lifting machine 31 starts to extend and controls the inner cover 32 to rise. The centrifugal separator 32 starts to guide the exhaust gas through the arc-shaped guide hood 35 to the lower end of the inner cover 32, and then draws it into the lower air inlet. After being pressurized by the centrifugal separator 33, it is discharged from the air outlet of the exhaust gas guide hood 2.

[0034] To accommodate adjustments to the size and angle of the exhaust port, an embedded electronically controlled exhaust hood 11 is movably mounted on the inner side of the exhaust hood 2.

[0035] In order to adjust the angle and flow rate of the exhaust port, the embedded electronically controlled exhaust hood 11 includes an arc-shaped first adjustment hood 111, an arc-shaped second adjustment hood 112, and a first control motor 113 and a second control motor 114 fixed to the upper end of the exhaust port hood 2.

[0036] The first control motor 113 is driven by the first output gear on the bottom output shaft meshing with the arc-shaped tooth groove on the arc-shaped first adjustment cover 111, and the second control motor 114 is driven by the second output gear on the bottom output shaft meshing with the arc-shaped tooth groove on the arc-shaped second adjustment cover 112.

[0037] By controlling the first control motor 113 and the second control motor 114 to rotate in both directions, the angle, position and size of the side outlet of the exhaust gas guide shroud 2 can be changed.

[0038] 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.
