Abstract
Description
Technical Field
[0001] This utility model relates to a slicing particle feeding device. Background Technology
[0002] In the nylon production industry, the melt after polymerization is pelletized by an underwater pelletizer, and the particles are then screened by vibration before being transported by water to the extraction tower for extraction. Before entering the extraction tower, the particles still need to undergo another water-particle separation process. The existing method has the following drawbacks:
[0003] 1. The particles after screening by the vibrating screen still have a lot of moisture, which will adhere to and remain on the feed pipe. Over time, this will cause the particles to turn yellow and oxidize, ultimately affecting product quality.
[0004] 2. Dead zones exist in the water-liquid separation vibrating screen before the extraction tower, which can also cause slices to remain stuck.
[0005] 3. Steam backflow may occur in the path from the vibrating screen to the feed pipe, affecting the feeding process. When the production capacity is large, it may cause blockage of the slices and affect production.
[0006] 4. During the water circulation process, there will be some loss and the concentration will gradually increase, which may lead to crystal precipitation and affect product quality. Utility Model Content

[0010] The spraying unit includes a demineralized water control valve, and the conveying circulation tank is equipped with a float level gauge, which is electrically connected to the demineralized water control valve.
[0011] Furthermore, there are a first water return pipe, a second water return pipe, and a third water return pipe; the drain outlet is connected to one end of the first water return pipe, the other end of the first water return pipe is connected to one end of the second water return pipe and one end of the third water return pipe respectively, the other end of the second water return pipe is connected between the particle screener and the conveying circulation tank; the other end of the third water return pipe is connected to the conveying circulation tank.

[0013] Furthermore, the fourth water return pipe is at a set angle to the tangent of the water circulation tank.
[0014] Furthermore, it also includes a flow-limiting orifice plate, which is disposed on the fourth water delivery return pipe.
[0015] The advantages of this utility model are:

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Figure 1 This is a schematic diagram of the principle of a slicing particle feeding device of this utility model. Detailed Implementation
[0021] Please see Figure 1 As shown, this utility model discloses a particle feeding device that feeds particles to an extraction tower a, comprising: a particle screener 1, a conveying and circulating tank 2, an ion water conveying pump 3, a water particle separation vibrating screen 4, and a spray unit 5; the spray unit 5 can be purchased directly from the market.
[0022] The particle screen 1 is connected to the bottom of the conveying circulation tank 2. The conveying circulation tank 2 is connected to the water particle separation vibrating screen 4 through the ion water conveying pump 3. The bottom of the water particle separation vibrating screen 4 is provided with a drainage port 41. The spray unit 5 is located above the water particle separation vibrating screen 4.
[0023] The spray unit 5 includes a demineralized water control valve 51. The conveying circulation tank 2 is equipped with a float level gauge 21, which is electrically connected to the demineralized water control valve 51. When the float level gauge 21 reaches the set position, it will control the demineralized water control valve 51 to close or open. The spray unit 5 has multiple nozzles, which can be aimed at the dead corner position of the water particle separation vibrating screen 4.
[0024] In this embodiment, preferably, it also includes a first water return pipe 6, a second water return pipe 7, and a third water return pipe 8; the drain outlet 41 is connected to one end of the first water return pipe 6, the other end of the first water return pipe 6 is connected to one end of the second water return pipe 7 and one end of the third water return pipe 8 respectively, the other end of the second water return pipe 7 is connected between the particle screen 1 and the conveying circulation tank 2; the other end of the third water return pipe 8 is connected to the conveying circulation tank 2; through this arrangement, a portion of water enters the pipe between the particle screen 1 and the conveying circulation tank 2, making the particle feeding process smoother and preventing blockage.
[0025] In this embodiment, preferably, a fourth water return pipe 9 is also included, one end of which is connected to the third water return pipe 8, and the other end of which is connected to the water circulation tank.
[0026] In this embodiment, preferably, the fourth water return pipe 9 and the cross-section of the conveying circulation tank 2 are at a set angle. Through this set angle, the water entering from the fourth water return pipe 9 drives the water in the conveying circulation tank 2 to rotate, forming a certain vortex, which facilitates particle conveying.
[0027] In this embodiment, preferably, a flow-limiting orifice plate b is also included. The flow-limiting orifice plate b is disposed on the fourth water return pipe 8 to ensure that sufficient demineralized water enters the second water return pipe 7. The flow-limiting orifice plate b is disposed between the second water return pipe 7 and the fourth water return pipe 9.
[0028] The circulating reflux water is used to rinse the water particle separation vibrating screen 4 and assist in feeding, so as to avoid the slices from being stuck and causing the slices to oxidize.
[0029] The particles entering the conveying circulation tank 2 from the particle screen 1 carry a certain amount of heat, which causes the demineralized water in the conveying circulation tank 2 to heat up. As a result, water vapor will drift away when the water-particle separation vibrating screen 5 is used, resulting in some water loss, which needs to be replenished. The spray unit 5 can wash the dead corners of the water-particle separation vibrating screen 4 and also replenish the conveying water in the conveying tank 2 to prevent the concentration of the conveying water from becoming higher and higher. The float level gauge 21 is used to interlock the opening and closing of the demineralized water control valve 51 to avoid water waste.
