Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber spinning equipment, in particular to a spinning box cleaning device. Background Art

[0002] Spinning is also known as chemical fiber forming. The forming of chemical fiber is the process of extruding the spinning fluid from the nozzle at a certain flow rate and then cooling and solidifying it into fiber. The spinning box includes a spinning box shell, a metering pump, a spinning branch pipe, and a spinning assembly. The metering pump is installed at the top of the spinning box shell and is connected to the spinning assembly through the spinning branch pipe. The spinning assembly is installed at the bottom of the spinning box body. The chemical fiber fluid is passed into the metering pump. The pressure of the fluid is stabilized by the metering pump, and each component fluid is evenly pumped into each spinning branch pipe, and then passed into the spinning assembly for mixed spinning. The spinning branch pipe is located below the metering pump and the spinning assembly is placed in the heating jacket below the spinning box shell. The space inside the spinning box shell and outside the heating jacket is filled with insulation material. Due to the increasing diversification of spinning raw materials, some spinning raw materials are prone to glue in the pipes through which the fluid flows. It is necessary to clean the pipes in the spinning box regularly, and the cleaning cycle is usually one year. The traditional way to clean a spinning box is to first shut down the spinning equipment to cool it down, remove the insulation material, cut open the heating jacket, and then calcine the spinning branch pipe and component chamber with an open flame. After calcination, the gelled fluid in the pipe will turn into ashes, which are then cleaned to complete the cleaning of the pipe in the spinning box.

[0003] The above-mentioned traditional cleaning method has the following problems:

[0004] 1) It is time-consuming, laborious and unsafe. The above-mentioned traditional cleaning method involves cutting open the heating jacket and using an open flame to calcine the melt pipe. After calcination, the heating jacket needs to be welded again to restore it.

[0005] 2) High cost; and the aforementioned traditional cleaning method requires shutdown during the cleaning process, affecting production; the spinning manifold is a pressure vessel, and each time it is cut open and welded back together, it needs to be tested for tightness, and each test takes at least 24 hours; when cleaning, depending on the actual situation, some need to be cleaned on the customer's site, and some need to dismantle the entire equipment and transport it to the maintenance workshop or supplier's factory for cleaning. The disassembly and transportation engineering is large, the construction period is long, and it consumes manpower and material resources, and the cleaning cost is high;

[0006] 3) Shorten the service life of the spinning box; the cleaning cycle of the spinning box is one year, and the box body needs to be disassembled every year, and then welded and sutured after cleaning, which greatly affects the service life of the spinning box. Utility Model Content

[0029] In this embodiment, referring to Figure 3 and Figure 4As shown in the figure, the spinning box 1 includes a spinning box housing (not shown in the figure). The metering pump is installed on the metering pump seat 11 at the upper end of the spinning box housing and is connected to each spinning branch pipe 12. The component chamber is installed at the lower end of the spinning box housing. The spinning components and the component chamber connector 13 detachably connected to the upper end of the spinning components are arranged in the component chamber. The component chamber connector 13 is installed on the upper top plate of the component chamber, with the lower end placed in the component chamber and connected to the spinning components. One end of the spinning branch pipe 12 is connected to the metering pump seat 11, and the other end is connected to the component chamber connector 13, so that the metering pump is connected to the spinning components through the spinning branch pipe 12. The part of the spinning branch pipe 12 below the metering pump and the component chamber are located in the heating jacket inside the spinning box housing. The space inside the spinning box 1 within the spinning box housing and outside the heating jacket is filled with heat-insulating materials. During spinning, the heating device installed in the spinning box 1 heats the spinning box 1 to make the fluid in the spinning branch pipe 12 at an appropriate temperature. When cleaning the spinning box 1, first remove the metering pump above the metering pump seat 11 and the spinning components below the component chamber connector 13. The heating device remains in the heating state. Connect the bottoms of multiple cleaning device bodies 2 to the component chamber connector 13 respectively, and connect multiple recovery devices 3 to the upper end of the metering pump seat 11 respectively.
