DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0031] like Figure 1-9The figure shows a filtering device of a textile setting machine described in this embodiment, which is connected to the exhaust gas outlet of the setting machine to preliminarily filter the waste heat gas discharged from the setting machine. The filtering device includes a tank body 1, a filter plate 2, a rotating shaft 3, and a driver. Among them, the tank body 1 is a cylindrical structure, which has a central axis and a chamber extending along the central axis. The two ends of the tank body 1 form an opening. Closing plates are installed at both ends of the tank body 1 to be able to cover the opening. An air inlet 12 and an exhaust port 11 are processed on the tank body 1. The air inlet 12 is connected to the exhaust gas outlet of the setting machine. The waste heat gas can enter the interior of the tank body 1 through the air inlet 12 and then be discharged from the exhaust port 11.

[0032] The filter plate 2 is arranged between the air inlet 12 and the exhaust port 11 so as to filter the waste heat. The aforementioned filter plate 2 is coaxially arranged inside the tank body 1 in a clearance fit manner and has a rotating state rotating around the central axis. Specifically, a central axis body 21 is coaxially processed on the filter plate 2. An axial hole 211 is processed inside the central axis body 21. A protruding structure extending in the axial direction is processed on the inner circumference of the axial hole 211. The rotating shaft 3 is coaxially installed inside the tank body 1, and the two ends of the rotating shaft 3 are rotatably connected to the end covers 14 on both sides through bearings. An axial groove structure is processed on the outer circumference of the rotating shaft 3 corresponding to the protruding structure. The rotating shaft 3 is plugged in and matched with the axial hole 211 in the axial direction, and the protruding structure is plugged in and matched with the axial groove in the axial direction to limit the relative rotation between the rotating shaft 3 and the filter plate 2. When the rotating shaft 3 rotates, it can synchronously drive the filter plate 2 to rotate. The driver is installed outside the tank 1 and is drivingly connected to one end of the rotating shaft 3 to drive the rotating shaft 3 to rotate, thereby driving the filter plate 2 to form the aforementioned rotating state. The driver is preferably a stepping motor in the prior art.

[0033] The filter plate 2 mentioned above is processed with a plurality of filter holes 22 distributed thereon. The filter hole 22 has a designed aperture, and can filter out fiber fluff in the waste heat. The aforementioned water collector 4 is arranged corresponding to the filter plate 2, which is inserted into the side wall of the tank body 1 and fixedly connected to the tank body 1 by screws. The water collector 4 has a first part 41 extending into the tank body 1 and a second part exposed to the tank body 1. A matching top surface is processed on the end of the first part 41 facing the central axis body 21, and the matching top surface is tightly matched and connected with the outer peripheral surface of the central axis body 21. Among them, the outer peripheral surface of the central axis body 21 mentioned above is a circular surface. Correspondingly, the matching top surface is an arc-shaped surface.

[0034] The first part 41 is processed with a water collecting chamber 411 inside. A avoidance groove 412 which is connected with the water collecting chamber 411 is processed on the top surface of the matching and located on the rotation path of the filter plate 2. Through the avoidance groove 412, the filter plate 2 can freely enter and exit the water collecting chamber 411 when rotating. The second part is processed with a drainage channel which is connected with the water collecting chamber 411 inside. In the aforementioned rotating state, through the avoidance of the avoidance groove 412, the filter plate 2 has a cleaning part which is inserted into the avoidance groove 412 and extends into the water collecting chamber 411. The area of ​​the cleaning part is determined according to the actual design. And in the aforementioned rotating state, the side wall of the avoidance groove 412 is tightly matched with the end face of the filter plate 2. In the specific design, a rubber pad can be arranged on the matching top surface, and the matching top surface is tightly matched with the outer peripheral surface of the central axis body 21 through the rubber pad. And a rubber layer is arranged on the side wall of the avoidance groove 412. The rubber layer is tightly matched with the end face of the filter plate 2. Through the above structural design, the above cleaning part is sealed in the water collecting chamber 411, and waste heat gas is difficult to enter the water collecting chamber 411. It should be noted that in actual application, a small amount or trace amount of waste heat gas still enters the water collecting chamber 411, but it does not affect the cleaning operation of the cleaning part.

[0035] Several water spraying parts are installed on both sides of the opposite sides of the cleaning part in the water collecting chamber 411. The water spraying part has a water spraying end facing the filter plate 2. The water sprayed by the water spraying part can be distributed to wash the corresponding filter holes 22 of the cleaning part. A water pipe is installed inside the water chamber. An assembly hole connected to the drainage channel is processed on the side wall of the second part. The first end of the water pipe is connected to the water spraying part, and the second end extends to the outside of the water collector 4 through the drainage channel and the assembly hole. The water pump is connected to the second end of the water pipe to input water flow into the water pipe. The above-mentioned water spraying part is preferably a water spraying nozzle of the prior art. A control valve body for opening and closing the drainage channel is processed on the aforementioned second part. When the water spraying part performs the cleaning operation, the control valve body is in an open state so that the water in the water collecting chamber 411 can be discharged through the drainage channel. When it is not cleaned, the control valve body is in a closed state to prevent the waste heat gas from overflowing through the drainage channel.

[0036] In this embodiment, a mixture discharge port 13 is processed on the tank body 1. The oil-water mixture formed by the condensation of the waste heat in the tank body 1 can be discharged through the mixture discharge port 13.

[0037] When in use, the waste heat gas discharged from the setting machine enters the tank body 1 through the air inlet 12, is filtered by the filter plate 2, and then discharged from the exhaust port 11. After a certain period of use, the filter plate 2 is driven by the driver to rotate a certain angle to drive a part of the filter plate 2 into the water collecting chamber 411, so as to form a cleaning part of the filter plate 2 in the water collecting chamber 411. The cleaning part is sealed and covered inside the water collecting chamber 411, effectively preventing the waste heat gas transported in the tank body 1 from entering the water collecting chamber 411. Water is transported to the water spraying part through the water pipe. The water spraying part sprays water to flush the filter holes 22 on the cleaning part to dredge the filter holes 22. The flushed water is collected by the water collecting chamber 411 and discharged from the drainage channel. After flushing, the filter plate 2 is driven to continue to rotate and move a certain angle, so that the cleaning part of the filter plate 2 entering the water collecting chamber 411 can be flushed in turn, thereby achieving a comprehensive flushing and cleaning of the filter holes 22 on the filter plate 2. Through the above method, the filtered fiber fluff can be cleaned by online cleaning, which effectively prevents the filter device from being blocked. There is no need to stop the machine frequently for cleaning, which effectively improves the fabric shaping processing efficiency and is highly practical.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
