DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0027] As Figures 1-10 shown, one embodiment of the present utility model discloses a high-temperature steam disinfection device for knitted plain cloth production, including disinfection box 1, the front side of disinfection box 1 is provided with operating port (not shown in the drawing), the front side of disinfection box 1 is hinged with box door (not shown in the drawing) through hinge at the position corresponding operating port. The left and right sides of disinfection box 1 are both provided with plain cloth inserting port 2, and the left and right sides of disinfection box 1 are respectively fixedly installed with feeding mechanism for conveying knitted plain cloth and winding mechanism for winding knitted plain cloth. The feeding mechanism 3 includes first fixed plate 30, the first fixed plate 30 is fixedly installed on one side of disinfection box 1, the front surface of first fixed plate 30 is fixedly connected with first inserting rod 31, the first inserting rod 31 is sleeved with feeding roller 32, and the surface of first inserting rod 31 and one end corresponding feeding roller 32 are threadedly connected with limiting nut 33. The winding mechanism 4 includes second fixed plate 40, the second fixed plate 40 is fixedly installed on the other side of disinfection box 1, the back surface of second fixed plate 40 is fixedly installed with winding motor 41, the output shaft of winding motor 41 penetrates to the outside of second fixed plate 40 and is fixedly connected with round plate 42, the front surface of round plate 42 is fixedly connected with second inserting rod 43, the second inserting rod 43 is sleeved with winding roller 44, and one end of the surface of second inserting rod 43 and corresponding winding roller 44 is threadedly connected with pressing nut 45. The knitted plain cloth body 7 is transmissionally connected between winding roller 44 and feeding roller 32, and the knitted plain cloth body 7 inserts through two plain cloth inserting ports 2.

[0028] The embodiment can achieve the following effects through the above arrangement. After the feeding roller with the knitted fabric roll is inserted into the first insertion rod, the limiting nut is screwed in to limit the end of the feeding roller. One end of the knitted fabric is inserted through the two fabric insertion ports in sequence through the operation port to form a connection with the winding roller. The switch valve of the external steam generating source is opened to allow high-temperature steam to be delivered to the inside of the sterilization box through the gas delivery pipe and sprayed out through the spray head mechanism. In this process, the winding motor is started, and the power output shaft of the winding motor rotates to drive the circular plate to rotate slowly. Under the pressure limiting of the pressure nut, the winding roller can be driven to rotate slowly. Therefore, the continuously wound fabric can be sterilized by the high-temperature steam sprayed by the spray head mechanism, and finally the winding roller with the knitted fabric after sterilization is removed from the second insertion rod.

[0029] The sterilization device also comprises a gas delivery pipe for delivering steam, the gas delivery pipe comprising a steam outer pipe 50 and a steam inner pipe 51 in communication with the steam outer pipe 50. The steam outer pipe 50 is sleeved with a fixing ring 500 at one end close to the steam inner pipe 51. The steam outer pipe 50 is sleeved with a fixing pipe 510 at one end away from the steam inner pipe 51, and the steam outer pipe 50 is in communication with the exhaust end of the steam generating device through the fixing pipe 510 at one end away from the steam inner pipe 51.

[0030] The steam inner pipe 51 is also provided with a fixing pipe 510 at one end close to the steam outer pipe 50, and the steam inner pipe 51 is closed at one end away from the steam outer pipe 50. The fixing pipe 510 is provided with an internal thread, and the fixing ring 500 is provided with an external thread. The internal thread and the external thread are threadedly connected.

[0031] The embodiment can achieve the following effects through the above arrangement. The steam outer pipe and the steam inner pipe are sleeved on the fixing ring through the fixing pipe. The steam outer pipe and the steam inner pipe are in close contact with each other at the end port through the thread connection of the fixing pipe and the fixing ring, and the interfaces are aligned, thereby completing the installation of the steam outer pipe and the steam inner pipe, and then completing the installation of the gas delivery pipe. Of course, the steam outer pipe and the steam inner pipe can be disassembled by unscrewing the fixing ring from the fixing pipe.

[0032] It should be noted that the above gas delivery pipe is suitable for the case where the external steam generating device is relatively close to the sterilization box. Only the splicing of the steam outer pipe and the steam inner pipe can achieve the near-distance delivery of steam.

[0033] When the external steam generating device is at a relatively long distance from the sterilization box, a steam inner pipe and a plurality of steam outer pipes can be arranged. The steam inner pipe and one of the steam outer pipes are connected by the method described above, and all the steam outer pipes are connected by the method described above. Two adjacent steam outer pipes can be connected by arranging one end of the fixed sleeve of one of the steam outer pipes in the fixed ring of the other steam outer pipe. The threaded connection of the fixed sleeve and the fixed ring allows the ports of the two adjacent steam outer pipes to be in close contact with each other, and the interfaces are aligned, thereby completing the connection of the two steam outer pipes. Similarly, the connection of several steam outer pipes can be completed, thereby forming a long steam outer pipe combination pipe, which can realize long-distance transportation of high-temperature steam and avoid the inconvenience of existing steam pipes, which are basically of an integral structure and have a long length, and are only spliced at corners.

[0034] In this embodiment, the steam outer pipe 50 is provided with a heat preservation layer 501, and the two ends of the heat preservation layer 501 are fixed on the steam outer pipe 50 by fasteners. The fastener is a fastening expansion piece 52, one end of which is an end screw-in head, and the other end is an expansion head, which is fixedly connected with the heat preservation layer 501.

[0035] The expansion head of this embodiment is a double-head conical spring wedge, which expands in the circumferential direction when the inner side is stressed. By moving the fastening expansion piece axially, the expansion degree of the expansion head can be adjusted, thereby adjusting the expansion force on the heat preservation layer of different thicknesses, ensuring that the heat preservation layer can be fixed on the steam outer pipe. When the heat preservation layer is replaced, the fastening expansion piece only needs to be loosened, which facilitates the replacement of the heat preservation layer. By arranging the heat preservation layer, the heat loss of the steam during transportation in the steam outer pipe is reduced.

[0036] In this embodiment, the fixed pipe 510 is sleeved with a sealing gasket 511, and the inner diameter of the fixed ring 500 is equal to the outer diameter of the steam inner pipe. The inner wall of the fixed ring 500 is in close contact with the outer wall of the steam inner pipe 51, and the port of the fixed ring 500 directly reaches the sealing gasket 511, which ensures the sealing of the interface of the connection between the steam inner pipe and the steam outer pipe, and avoids the leakage of steam.

[0037] The end of the steam inner pipe 51 away from the steam outer pipe 50 is closed and located inside the sterilization box 1, and the steam inner pipe 51 is connected with a plurality of jet mechanisms for spraying steam. Each jet mechanism includes a Venturi tube 60, the upper end of which is connected with the steam inner pipe 51, and at least one output hole 61 is arranged on the side wall of the lower end of the Venturi tube 60. A bottom cover 62 is coaxially arranged at the lower end of the Venturi tube 60. A plurality of exhaust holes 63 are arranged around the Venturi tube 60 on the lower end surface of the bottom cover 62. The gas-liquid mixture discharged from the output hole 61 can impact the side wall of the bottom cover 62 to accelerate the dispersion of water vapor.

[0038] The output hole 61 is arranged opposite to the side wall of the bottom cover 62; the Venturi tube 60 has a throat pipe 64 in the middle, and the minimum inner diameter of the throat pipe 64 is smaller than the inner diameters of the two ends of the Venturi tube 60; the throat pipe is arranged to form a turbulent flow near the end close to the output hole when the liquid proportion in the water-gas mixture is high, which is beneficial to the preliminary separation of the gas and liquid and improves the water vapor generation efficiency.

[0039] The bottom cover 62 is coaxially provided with an umbrella-shaped flange 65 around the bottom end of the Venturi tube 60; the umbrella-shaped flange is arranged to block the water flow from being sprayed below the horizontal plane, and also guide the sprayed liquid to form a water curtain to accelerate the dispersion of the water vapor and spray it towards the exhaust hole. The edge of the umbrella-shaped flange 65 is lower than the output hole 61. The exhaust hole 63 is located between the umbrella-shaped flange 65 and the side wall of the bottom cover 62. The throat pipe is arranged to form a turbulent flow near the end close to the output hole when the liquid proportion in the water-gas mixture is high, which is beneficial to the preliminary separation of the gas and liquid and improves the water vapor generation efficiency.

[0040] The steam generated by the steam generation device enters the Venturi tube through the steam outer pipe and the steam inner pipe in the embodiment, and at this time, the steam entering the Venturi tube is actually a water-gas mixture. When the water-gas mixture is discharged from the output hole, it collides with the inner wall of the bottom cover to make the water mist converge and flow down along the inner wall, and the collision is beneficial to the acceleration and dispersion of the water vapor to form, and the high-temperature water vapor escapes from the exhaust hole downwards to sterilize the knitted fabric. Therefore, the knitted fabric is sterilized by the high-temperature water vapor, and the water mist is prevented from being sprayed to the knitted fabric as much as possible.

[0041] Finally, it should be pointed out that the above only describes and explains the specific embodiments of the utility model in detail. However, the utility model is not limited to the above described specific embodiments. The equivalent modifications and substitutions of the utility model made by the person skilled in the art are also within the scope of the utility model. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the utility model are covered within the scope of the utility model.
