Description

Technical Field

[0001] This utility model relates to an anti-clogging feeding device, belonging to the field of feeding pipelines. Background Technology

[0002] Chemical fibers (also known as synthetic fibers) are fibrous materials made by processing natural or synthetic polymers through chemical processes. Chemical fiber raw materials can be divided into synthetic fiber raw materials (such as polyester, nylon, and polypropylene) and recycled fiber raw materials (such as wood pulp, bamboo pulp, and waste cotton). These raw materials are transformed into fibers through different chemical and physical processes, and ultimately processed into various textiles, widely used in clothing, home furnishings, and industrial fields.

[0003] In the process of chemical fiber production, in order to whiten the chemical fiber and improve its UV resistance, titanium dioxide is added to the chemical fiber raw materials. During the addition of titanium dioxide, powdered titanium dioxide is put into the hopper, and the titanium dioxide in the hopper then enters the preparation tank through the feeding pipe. However, powdered titanium dioxide is prone to blockage in the feeding pipe, affecting the normal feeding of titanium dioxide.

[0004] Therefore, a clog-proof feeding device is needed to prevent blockage during titanium dioxide feeding. Utility Model Content

The sealing ring is located at the annular groove and is used to seal the annular groove. An air pipe is connected to the sealing ring, and the air pipe is connected to an external air supply system. Nitrogen gas is transported from the air pipe to the annular groove through the air supply system.

[0027] like Figure 1-6 As shown, an anti-clogging feeding device in this embodiment includes a pipe body 1, with its two ends distributed vertically. Specifically, the pipe body 1 is arranged vertically, and an annular groove 2 is provided on the outer peripheral wall of the pipe body 1. A through hole 3 is provided on the annular groove 2, and the annular groove 2 communicates with the internal cavity of the pipe body 1 through the through hole 3. Multiple through holes 3 are provided, and the multiple through holes 3 are evenly distributed circumferentially with the axis of the pipe body 1 as the center. The through holes 3 are arranged inclined from top to bottom towards the axis of the pipe body 1. A sealing ring 4 is fixedly sleeved on the outer peripheral wall of the pipe body 1. The sealing ring 4 is located at the annular groove 2 and is used to seal the annular groove 2. An air pipe 5 is connected to the sealing ring 4, and the air pipe 5 is connected to an external air supply system. Nitrogen gas is transported from the air pipe 5 to the annular groove 2 through the air supply system.

[0028] During operation, the top of the pipe body 1 is connected to the hopper, and the bottom of the pipe body 1 is connected to the mixing tank. After the powdered titanium dioxide is put into the hopper, it is transported from the pipe body 1 to the mixing tank. During this period, the gas supply system transports nitrogen from the gas pipe 5 to the annular groove 2. The nitrogen in the annular groove 2 is then transported from the through hole 3 to the cavity of the pipe body 1. Under the action of the airflow, the titanium dioxide blocked in the pipe body 1 is discharged downward, thus achieving anti-clogging.

[0029] A knife gate valve 6 is provided on the pipe body 1. The knife gate valve 6 is located above the through hole 3. When nitrogen is delivered into the pipe body 1 through the through hole 3, the knife gate valve 6 is closed to prevent the gas and titanium dioxide in the pipe body 1 from being discharged upward. During normal feeding of the pipe body 1, the main gate valve can be opened.

[0030] The pipe body 1 includes an upper pipe section 101, a middle pipe section 102, and a lower pipe section 103 connected sequentially from top to bottom. The knife gate valve 6 is located on the upper pipe section 101, and the annular groove 2 and the sealing ring 4 are both located on the lower pipe section 103. The middle pipe section 102 is made of flexible material. Specifically, the middle pipe section 102 is a corrugated pipe. During installation, the flexible middle pipe section 102 facilitates the adjustment of the upper pipe section 101 according to the position of the hopper.

[0031] A positioning block 7 is fixedly installed on the lower pipe section 103, and the bottom of the sealing ring 4 abuts against the top of the positioning block 7. The positioning block 7 is used to position the sealing ring 4 on the lower pipe section 103.

[0032] The sealing ring 4 is detachably and fixedly connected to the lower pipe section 103 by the locking member 8, which can be a screw.

[0033] The trachea 5 is equipped with a vibration component. The flow of gas in the trachea 5 is used as the driving force to make the vibration component vibrate the trachea 5. The vibration is transmitted to the lower pipe section 103 through the sealing ring 4, which facilitates the discharge of titanium dioxide blockage in the lower pipe section 103.

[0034] The vibration assembly includes a rotating shaft 9, which is coaxially arranged with the air pipe 5. The rotating shaft 9 is rotatably connected to the air pipe 5 through a bearing 10. A fan blade 11 is installed at one end of the rotating shaft 9. Multiple elastic plates 12 are fixedly arranged on the rotating shaft 9. The multiple elastic plates 12 are evenly distributed circumferentially around the axis of the rotating shaft 9. Multiple fixed plates 13 are arranged on the inner wall of the air pipe 5. The multiple fixed plates 13 and the multiple elastic plates 12 are arranged in a cross pattern. When nitrogen flows in the air pipe 5, it drives the fan blade 11 to rotate. The rotation of the fan blade 11 drives the drive shaft to rotate on the bearing 10, and causes the elastic plates 12 to rotate synchronously. During the rotation of the elastic plates 12, they intermittently strike the fixed plates 13, thereby causing the fixed plates 13 to vibrate, that is, the air pipe 5 to vibrate. The vibration is transmitted to the lower pipe section 103 through the sealing ring 4.

[0035] In summary, by delivering nitrogen gas through the through hole 3 into the tube 1, the titanium dioxide blocking the tube 1 is discharged downwards, thus preventing blockage. In addition, the vibration component causes the tube 1 to vibrate, which facilitates the discharge of titanium dioxide from the tube 1.

[0036] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
