Description
Technical Field
[0001] The utility model relates to the technical field of textile production, in particular to a novel FDY slice spinning pre-crystallizer. Background Art
[0002] At present, most of the pre-crystallizers used in FDY polyester filament chip spinning production are fluidized bed crystallizers. The crystallization area of the pre-crystallizer is mainly composed of three crystallization areas, namely, the heated agglomeration area, the crystallization hardening area, and the slice uniform area. After the material falls into the pre-crystallizer from the wet material bin, it first exchanges heat and power with the crystallization wind in the heated agglomeration area, so that the material passes through the crystallization bed baffle successively, slowly enters the crystallization hardening area and the uniform area, and finally comes to the material thickness baffle. At this time, the material has completed pre-crystallization. The material thickness baffle is used to control the thickness of the crystallization bed material. When the thickness reaches a certain value, under the boiling blowing of the crystallization wind, the material jumps over the upper edge of the material thickness baffle and falls into the drying tower from the discharge port.
[0003] The traditional crystallization bed is welded horizontally in the pre-crystallizer cavity. After the pre-crystallization is completed, a part of the material will be retained on the crystallization bed. The material needs to be drained to prevent affecting the subsequent pre-crystallization effect. If it is not drained, the retained material will be solid-phase condensed, degraded, and yellowed. The degraded and yellowed material will enter the drying tower together with the new material, and eventually become the spinning raw material. The spinning raw material with the degraded masterbatch will cause uneven spinning melt and contain degradation impurities after melt spinning. The production will have an increase in hairy and broken wires, which will reduce the product quality. However, due to the material thickness baffle between the discharge port and the crystallization bed, the material cannot be discharged directly to the discharge port, which wastes material and is inefficient. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the invention
[0004] In view of the above-mentioned deficiencies, the purpose of the utility model is to provide a new type of FDY chip spinning pre-crystallizer. When the material is pre-crystallized completely, the discharge baffle can be rotated to open and close, and the material on the crystallization bed falls from the discharge port into the discharge port, with high material recovery rate and high discharge efficiency.

DETAILED DESCRIPTION
[0032] The utility model is further described below in conjunction with the accompanying drawings.

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0034] Please refer to Figure 1-Figure 4 An embodiment of the utility model provides a novel FDY chip spinning pre-crystallizer, comprising a shell 1 defining an inner cavity, a first baffle 2 and a second baffle 3 arranged at intervals in the inner cavity, and a crystallization bed 4 arranged at the bottom of the inner cavity, wherein the shell 1 is provided with a feed inlet 101 and an air outlet 102, and a discharge port 105 and at least one air inlet are arranged on the bottom surface of the shell 1, wherein the feed inlet 101, the discharge port 105, the air inlet and the air outlet 102 are connected to the inner cavity, and the first baffle 2 and The second baffle 3 is respectively fixedly connected to the cavity wall of the inner cavity, the first baffle 2 and the second baffle 3 are located above the crystallization bed 4, the air inlet is located below the crystallization bed 4, a material discharge thickness baffle 5 is arranged above the crystallization bed 4, a discharge port 6 is arranged between the material discharge thickness baffle 5 and the crystallization bed 4, the discharge port 6 is rotatably provided with a discharge baffle 7, the discharge baffle 7 is rotatably connected to the shell 1, and the material discharge thickness baffle 5 is fixedly connected to the cavity wall of the inner cavity.
[0035] Specifically, the number of air inlets is 2, namely, the first air inlet 103 and the second air inlet 104. The crystallization bed 4 is a porous structure. The discharge baffle 7 is aligned with the outer edge of the crystallization bed 4. The porous structure facilitates the vertically upward crystallization wind to boil and crystallize the material. The first baffle 2, the second baffle 3 and the discharge thickness baffle 5 are arranged in parallel and spaced apart. The first baffle 2 and the second baffle 3 divide the crystallization bed 4 into three crystallization zones, which are the heated agglomeration zone 401, the crystallization hardening zone 402 and the slicing uniform zone. 403, the feed port 101 is arranged on the upper side of the shell 1, and the air outlet 102 is located at the upper part of one side of the shell 1. After the material accumulates to a certain thickness, the crystallization wind enters from the air inlet. Under the boiling blowing of the crystallization wind, the material jumps over the material thickness baffle 5 and enters the drying tower from the discharge port 105. After the pre-crystallization is completed, the discharge baffle 7 is rotated and opened, and the crystallization wind is introduced into the air inlet to sweep the material on the crystallization bed 4, and the material will be discharged from the discharge port 6 into the discharge port 105, thereby improving the material recovery rate and discharge efficiency, and preventing material retention from affecting the subsequent spinning quality.
[0036] like Figure 3 and Figure 4 As shown, the crystallization bed 4 is provided with a guide plate 8 along its edge. Furthermore, the guide plate 8 is a rounded plate. The crystallization bed 4 is installed in the inner cavity by means of a slot or welding. Since right-angled corners and installation gaps are formed between the crystallization bed 4 and the cavity wall of the inner cavity, materials are easily retained in the corners or installation gaps. Long-term stagnation of materials will lead to solid-phase condensation, degradation, and yellowing of the materials. The degraded and yellowed materials will enter the drying tower together with the new materials and eventually become spinning raw materials. The spinning raw materials with degraded materials will lead to uneven spinning melt and contain degradation impurities after melt spinning, resulting in increased hairy and broken fibers in production, and lowering product quality. After the guide plate 8 is installed, the materials will be guided and blocked by the guide plate 8 and will not be retained in the corners or installation gaps. The surface of the rounded plate is an arc surface, and the materials will roll on the rounded plate and will not be retained on the guide plate 8.
[0037] like Figure 4 As shown, the shell 1 is provided with a compressed air purge port 9 which runs horizontally through the shell 1, and a compressed air nozzle for purging materials is horizontally inserted into the compressed air purge port 9, and the compressed air nozzle is installed in the compressed air purge port 9, and the compressed air nozzle is connected to a compressed air hose, and the compressed air nozzle faces the discharge port 6. Compressed air is passed into the compressed air hose, and the compressed air pressure is set to 0.1Mpa. A solenoid valve is set between the compressed air hose and the compressed air nozzle to control the start and stop. During the discharge process, the vertically upward crystallization wind cannot clean the materials in the installation gap of the discharge baffle 7, resulting in the discharge baffle 7 not being tightly closed when it is closed again after the discharge is completed, which will cause the risk of uncrystallized materials leaking into the drying tower for subsequent production, causing agglomeration and interrupting the production. When the production is terminated, the compressed air nozzle will clean the discharge port 6 horizontally and clean the materials in the installation gap of the discharge baffle 7.
[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the shell 1 is rotatably inserted with a rotating shaft, and the discharge baffle 7 is sleeved on the rotating shaft. One end of the rotating shaft is detachably provided with an operating handle 10 located on the outside of the shell 1. The operator manually rotates the discharge baffle 7 to open and close the discharge baffle 7, which is more convenient to operate.
[0039] like Figure 1 As shown, each crystallization zone is provided with a mirror 11 for observing the condition of the crystallization zone. The mirror 11 is embedded in the shell 1 , and each crystallization zone observes the crystallization condition of the material through the mirror 11 .
[0040] like Figure 1-Figure 3 As shown, the shape of the discharge port 105 is a trapezoidal structure with an inner diameter gradually decreasing from top to bottom, and the discharge port 105 with a gradually changing width controls the discharge amount.
[0041] like Figure 1 As shown, the upper side of the shell 1 is a step structure, which guides the crystallized wind to the air outlet 102 for discharge, thereby achieving a better exhaust effect.
[0042] The working process of the crystallizer provided by a preferred embodiment of the utility model is as follows:
[0043] Crystallization wind is introduced into the air inlet, and the crystallization wind passes vertically through the crystallization bed 4. First, in the heated agglomeration zone 401, the material passes through the first baffle 2 and the second baffle 3 in turn by exchanging heat and power with the crystallization wind, and slowly enters the crystallization hardening zone 402 and the uniform zone, and finally reaches the thickness baffle of the crystallization bed 4. At this time, the material has completed pre-crystallization. The height of the thickness baffle of the crystallization bed 4 is used to control the thickness of the material laid on the crystallization bed 4. When the material thickness reaches a certain height, under the boiling blowing of the crystallization wind, the material jumps over the upper edge of the discharge thickness baffle 5 and falls into the drying tower from the discharge port 105. When the material cannot jump over the discharge thickness baffle 5, the staff turns the operating handle 10 to open the discharge baffle 7. The crystallization wind continues to blow, discharges the material from the discharge port 6, and enters the drying tower from the discharge port 105. After the production is completed, the compressed air nozzle is opened to purge the discharge port 6 to blow the material into the drying tower.
