Description

Technical Field

[0001] The utility model belongs to the technical field related to material adding equipment, in particular to a powder bin suitable for feeding solid additives. Background Art

[0002] Spandex is the abbreviation of polyurethane fiber, which is an elastic fiber, generally composed of multiple filaments, with high extensibility (500%~700%), low elastic modulus (200% elongation, 0.04~0.12 g / denier) and high elastic recovery rate (200% elongation, 95%~99%). Except for its greater strength, other physical and mechanical properties are very similar to those of natural latex. It is more resistant to chemical degradation than latex, has moderate thermal stability, and its softening temperature is about 200°C or above. Most dyes and finishing agents used for synthetic fibers and natural fibers are also suitable for dyeing and finishing of spandex. Spandex is resistant to sweat, seawater, various dry cleaning agents and most sunscreens. It will also fade after long-term exposure to sunlight or in chlorine bleach, but the degree of fading varies greatly depending on the type of spandex, and can be used for clothing that needs to be stretched to meet comfort requirements.

[0003] At present, when spandex is produced, its raw materials are introduced into the production equipment through a straight tube. However, the straight tube has great constraints on the raw materials, resulting in leakage, increased moisture, material sticking to the wall of the pipe, and inability to flexibly control the feeding time. Utility Model Content

[0004] The utility model aims to provide a powder bin suitable for feeding solid additives, which solves the problems of leakage, increased moisture, material sticking to the wall of the pipeline and inflexible feeding time when feeding spandex raw materials by arranging a powder tank and a top cover.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a powder material bin suitable for feeding solid additives, comprising a powder material tank. When in use, the tank body is first fixed to the feeding port of the material production equipment through the flange at the lower end, and then the lower blowing port and the upper blowing port are respectively connected to the nitrogen pipeline, and the recovery pipeline is connected to the recovery port, and then the feeding pipeline is placed on the metering hopper for use. During use, the raw material will enter the inside of the metering hopper, and after the metering hopper receives a specified amount of raw material, it will put the raw material into the inside of the tank body. After the raw material enters the tank body, it will accumulate inside the tank body and enter the inside of the production equipment along the tank body. At the same time, the high material level meter and the low material level meter monitor the accumulation of the raw material, and the vibrator will vibrate the tank body to promote the sliding of the raw material, so as to realize the feeding of the raw material. The powder material tank comprises a tank body and a cover body, and a plurality of lower blowing ports are arranged at equal angles on the side of the tank body. The surface of the tank body between the lower blowing ports is fixedly connected with the high material level meter and the low material level meter, and the side of the tank body is fixedly connected with the vibrator at the middle position of the path with the maximum inclination angle;

[0007] The upper end of the tank body is fixedly connected to a cover body, a plurality of upper blowing ports are arranged on the surface of the cover body, and a metering hopper is fixedly connected to the cover body at a position corresponding to the discharge port of the tank body; through the arrangement of the tank body, the lower blowing port, the vibrator, the high material level meter, the low material level meter, the cover body, the upper blowing port and the metering hopper, the metering, backlog monitoring, vibration-assisted feeding, storage, cleaning and automatic unloading of the put-in raw materials can be carried out. Compared with the original feeding pipe, not only can it be calculated whether the put-in solid additives are sufficient, but also the direct contact between the batching tank and the atmosphere can be isolated, the moisture content of the additives can be reduced, and the residual amount of the feeding pipeline can be effectively reduced. A batch of solid additives can also be stored in advance, and the feeding time can be flexibly controlled.

[0008] Furthermore, the cross section of the tank body is a right-angled trapezoid.

[0009] Furthermore, the inner wall of the tank body is sprayed with tetrafluoroethylene.

[0010] Furthermore, there are eight lower blowing ports and eight upper blowing ports in total.

[0011] Furthermore, the high material level meter and the low material level meter are located on the same straight line path.

[0012] Furthermore, a flange is fixed to the feed port of the tank body, and is fixed to the feed port of the material production equipment through the flange.

[0013] The utility model has the following beneficial effects:

[0014] 1. The amount of solid additives can be calculated to prevent insufficient or wrong addition;

[0015] 2. It can isolate the direct contact between the batching tank and the atmosphere, reducing the moisture content of the additive by about 500PPM;
