Description

Technical Field

[0001] The present application relates to the technical field of spinneret cleaning, and in particular to a spinneret cleaning and calcining device and method. Background Art

[0002] The spinneret needs to be cleaned after being used for a period of time. One of the existing cleaning methods is to place the spinneret directly in a hanging basket and send it into a calcining furnace for calcination to remove the attachments. Figure 1 The existing hanging basket is provided with multiple partitions 01 for supporting the spinneret, but the intervals between the multiple partitions 01 are large, and fewer spinnerets can be placed at a time. Therefore, when calcining the spinneret, the calcining furnace needs to be started multiple times, resulting in higher energy consumption for calcining the spinneret. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, one of the purposes of this application is to provide a spinneret cleaning and calcining device and method, which has the advantages of increasing the number of spinnerets in a single calcination, reducing the number of startups of the calcination furnace, and consuming less energy to calcine the spinnerets.

[0004] The above-mentioned purpose of this application is achieved through the following technical solutions:

[0005] A spinneret cleaning and calcining device comprises a hanging basket and a plurality of support frames. The support frames are provided with a support layer, the support layer is used to support the spinneret, and the support layer is hollowed out.

[0006] By adopting the above technical solution, multiple support frames are set up, and a support layer is provided on the support frame for placing the spinneret. In use, by placing the spinneret on the support frame and placing the support frame in the hanging basket, the purpose of placing multiple spinnerets in the calcining furnace for calcination at a time can be achieved, so that when the same number of spinnerets are calcined, the energy consumption is relatively low.

[0007] In a preferred example, the present application can be further configured as follows: it also includes a positioning device, the positioning device includes a positioning assembly, the positioning assembly includes a positioning plate and a positioning airbag installed on the positioning plate, the positioning plate is installed on the support layer, and the positioning airbag forms a positioning cavity for accommodating the spinneret.

[0008] By adopting the above technical solution, the positioning airbag forms a positioning cavity, which makes it possible to position the spinneret and reduces the probability of the spinneret falling during the process of moving the support frame.

[0009] In a preferred example, the present application can be further configured as follows: the positioning device also includes a connecting pipe, there are multiple positioning components, and the connecting pipe connects multiple positioning airbags.

[0010] By adopting the above technical solution, the existence of the connecting pipe enables the pressures of multiple positioning airbags to be connected.

[0011] The present application also discloses a method for cleaning and calcining a spinneret: comprising the following steps: a loading step, connecting the positioning plate and the support layer, and introducing gas into the positioning airbag through a connecting pipe so that the pressure in the positioning airbag reaches a preset range; a placing step, placing the spinneret in the positioning cavity, and the spinneret squeezes the cavity wall of the positioning cavity; a hoisting step, hoisting the support frame into the hanging basket; a dismantling step, discharging the gas in the positioning airbag through the connecting pipe so that the cavity wall of the positioning cavity does not contact the spinneret; removing the positioning plate from the support layer; and a calcining step, placing the hanging basket in a calcining furnace for calcination.

[0012] By adopting the above technical solution, that is, by placing the spinnerets on the support layer during use, more spinnerets can be placed and positioned through the positioning cavity, thereby reducing the probability of the spinnerets falling.

[0013] In a preferred example, the present application can be further configured as follows: in the placement step, the pressure changes in the connecting pipe are monitored. If the pressure shows a downward trend, the downward trend is judged. If it meets the standards, repair preparations are carried out. If it does not meet the standards, a pressure maintaining step is carried out.

[0014] By adopting the above technical solution, since the positioning airbag and the connecting tube are connected, and when the spinneret is placed, the positioning airbag is squeezed, the overall pressure will increase, that is, the pressure will show an upward trend, that is, the other positioning airbags will expand, compressing the space of the positioning cavity, so that a smaller amount of gas can be used to achieve a better positioning effect on the spinneret. During this process, if there is a pressure drop, it means that there is a pressure leakage. If the pressure leakage meets the standard, that is, the pressure leakage rate is small, that is, the pressure can maintain the positioning effect on the spinneret during the removal step, then preparation for repair is carried out. If it does not meet the standard, that is, the pressure leakage rate is fast, the pressure can maintain the positioning effect on the spinneret during the removal step, and pressure is maintained at this time.

[0015] In a preferred example, the present application can be further configured as follows: a pressure maintaining step, in which gas is introduced into the connecting tube so that the gas pressure in the connecting tube is within a preset range.

[0016] By adopting the above technical solution and the pressure maintaining step, it is possible to maintain a good positioning effect on the spinneret.

[0017] In a preferred example, the present application can be further configured as follows: it also includes a leak detection step, the positioning airbags of one or more positioning components constitute a pressure unit, the connecting pipe and the pressure unit are connected by a valve, when the spinnerets in the hanging basket do not reach the preset number, and the support frame has a pressure holding step and enters the hanging basket, the pressure holding step is canceled, and the valve connecting the connecting pipe and the pressure unit is closed, if there is a gas leak in one or more pressure units, the corresponding pressure units are marked, if there is no gas leakage in the pressure unit, the pressure in the connecting pipe is judged, if the pressure decreases, the connecting pipe is marked, and then the valve is opened to release the pressure through the connecting pipe.

[0018] By adopting the above technical solution, when the number of spinnerets in the hanging basket does not reach the preset number, the spinnerets need to be placed in the hanging basket. Therefore, by closing the valve, the pressure relief point can be detected, which saves time.

[0019] In a preferred example, the present application can be further configured as follows: when the number of spinnerets in the hanging basket reaches a preset number, the gas in the positioning airbag is discharged through the connecting pipe.

[0020] By adopting the above technical solution, when the number of spinnerets in the hanging basket reaches the preset number, it indicates that the calcination step is about to be carried out, so the gas in the positioning airbag needs to be discharged for calcination.

[0027] The present application is further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 2-Figure 5, which is a spinneret cleaning and calcining device disclosed in this application, includes a hanging basket 3, a positioning device and multiple support frames 1. The support frame 1 is provided with multiple support layers 11, which are used to support the spinneret. The support layer 11 is hollowed out, and a lifting ring is also provided on the support frame 1.

[0029] The positioning device includes a positioning assembly 2 and a connecting tube 4. There are multiple positioning assemblies 2 and they correspond one to one with the connecting tubes 4. The positioning assembly 2 includes a positioning plate 21 and a positioning airbag 22 mounted on the positioning plate 21. The positioning plate 21 and the support layer 11 are detachably connected. For example, the positioning plate 21 is adsorbed on the support layer 11 by a magnet. The positioning airbag 22 forms a positioning cavity 23 for accommodating a spinneret. The spinneret can be a short fiber spinneret.

[0030] The positioning airbags 22 of one or more positioning assemblies 2 constitute a pressure unit. The connecting pipe 4 and the pressure unit are connected through a valve, so that the multiple positioning airbags 22 are connected. In this embodiment, one pressure unit includes one positioning airbag 22.

[0031] The present application also discloses a method for calcining a spinneret, which uses the above-mentioned spinneret cleaning and calcining device, comprising the following steps:

[0032] In the loading step, the positioning plate 21 and the support layer 11 are connected, and gas is introduced into the positioning airbag 22 through the connecting pipe 4 so that the pressure in the positioning airbag 22 reaches a preset range;

[0033] In the placement step, the spinneret is placed in the positioning cavity 23 and squeezed against the cavity wall of the positioning cavity 23. The pressure change in the connecting pipe 4 is monitored. If the pressure shows a downward trend, the downward trend is judged. If it meets the standard, repair preparation is carried out. If it does not meet the standard, the pressure maintenance step is carried out.

[0034] In the pressure-maintaining step, gas is introduced into the connecting pipe 4 so that the air pressure in the connecting pipe 4 is within a preset range. The width of the positioning cavity 23 where the spinneret is not placed is determined. If the width does not meet the standard, that is, the width is less than the minimum value, the pressure-maintaining step is canceled and a warning is given that the pressure sensor is damaged.

[0035] Hoisting step: hoisting the support frame 1 into the hanging basket 3;

[0036] Leakage detection step: when the number of spinnerets in the hanging basket 3 does not reach the preset number, and the positioning device corresponding to the support frame 1 has a pressure holding step and the support frame 1 enters the hanging basket 3, the pressure holding step is canceled, and the valve connecting the connecting pipe 4 and the pressure unit is closed. If there is a gas leak in one or more pressure units, the corresponding pressure unit is marked. If there is no gas leak in the pressure unit, the pressure in the connecting pipe 4 is judged. If the pressure decreases, the connecting pipe 4 is marked, and then the valve is opened to release the pressure through the connecting pipe 4. When the number of spinnerets in the hanging basket 3 reaches the preset number, the removal step is performed;

[0037] In the removal step, the gas in the positioning airbag 22 is discharged through the connecting pipe 4 so that the cavity wall of the positioning cavity 23 is not in contact with the spinneret, and the positioning plate 21 is removed from the support layer 11;

[0038] In the calcining step, the hanging basket 3 is placed in a calcining furnace for calcining.

[0039] The implementation principle of this embodiment is: by placing the spinneret on the support layer 11 on the support frame 1, more spinnerets can be placed in the hanging basket 3 at a time, and by using the positioning device, the probability of the spinneret falling during the transfer process is reduced.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
