Description

Technical Field

[0001] The utility model relates to the technical field of spinning solution treatment, in particular to a spinning solution degassing device. Background Art

[0002] Spinning solution degassing is a very important step in the spinning process. The purpose of degassing is to remove the bubbles in the spinning solution to ensure the quality and stability of spinning. Common spinning solution degassing methods include static degassing, vacuum degassing, centrifugal degassing, etc. Through these methods, the bubbles in the spinning solution can be effectively reduced and the uniformity and strength of spinning can be improved.

[0003] The Chinese utility model patent with the announcement number CN214913616U discloses a degassing device, which welds a mesh plate on the arc cover of the degassing cylinder to disperse the spinning solution entering the degassing cylinder, so that the remaining liquid is dispersed to each through hole and then flows down in multiple streams, thereby improving the degassing effect during the circulation process. However, in this technical solution, the distance between the mesh plate and the arc cover is certain, and the spinning solution with high viscosity often cannot flow down quickly from the through hole of the mesh plate, but will accumulate on the top of the mesh plate, thereby affecting the feeding. In addition, since there is a distance between the outer edge of the mesh plate and the inner wall of the degassing cylinder, the spinning solution accumulated on the mesh plate is easy to flow down from the gap between the mesh plate and the inner wall of the degassing cylinder, so that this part of the spinning solution is not diverted by the mesh plate, affecting the degassing effect. Summary of the invention

[0004] In view of the defects in the prior art, the technical problem to be solved by the utility model is to provide a spinning solution degassing device, which is provided with a height-adjustable diverter plate so as not to affect the feeding of the spinning solution.

[0005] To solve the above technical problems, the utility model provides a spinning liquid degassing device, including a tank body, a degassing chamber with an open top formed inside the tank body, and a discharge port is arranged at the bottom of the tank body; a tank cover, which is sealed and connected to the top of the tank body, and a feed port is arranged on the tank cover; a diverter plate is arranged in the degassing chamber, and the outer wall of the diverter plate is slidably matched with the side wall of the degassing chamber, the diverter plate divides the degassing chamber into a buffer chamber and a static chamber up and down, and a plurality of through holes connecting the buffer chamber and the static chamber are arranged on the diverter plate; a lifting device, including at least two sliding rods, which are slidably penetrated on the tank cover, and one end of the sliding rod extending into the tank body is connected to the diverter plate; a reset member, which is sleeved on the outer periphery of the sliding rod, and a limiting head is arranged at the end of the sliding rod away from the tank cover, and the two ends of the reset member are respectively abutted against the tank cover and the limiting head.

[0006] Preferably, the diverter plate comprises a bottom plate, the outer edge of which is extended upward to provide a side plate, the outer wall of which is slidably matched with the side wall of the degassing chamber; and the through hole is provided on the bottom plate.

[0007] Preferably, the upper surface of the side plate gradually slopes downward in a direction away from the side wall of the degassing chamber.

[0008] Preferably, the bottom of the tank body is connected with supporting legs.

[0009] Preferably, the through holes are evenly distributed around the circumference of the bottom plate.

[0010] Preferably, the reset element is a spring.

[0011] Preferably, the tank cover is provided with a through hole cooperating with the sliding rod, and a sealing ring is embedded in the inner circumference of the through hole.

[0012] Preferably, the discharge port is located in the middle of the bottom wall of the degassing chamber, and the bottom wall of the degassing chamber gradually slopes upward in a direction away from the discharge port.

[0013] The utility model has the following beneficial effects: in the utility model, the spinning solution flows into the buffer chamber from the feed port of the tank cover and falls on the diverter plate, and a plurality of through holes are arranged on the diverter plate. The spinning solution flows into the static chamber through the through holes under the action of gravity. After passing through the diverter plate, the spinning solution is diverted into multiple streams of fluid, which increases its surface area, and enables the bubbles in the spinning solution to escape quickly, thereby improving the degassing effect. Due to the small inner diameter of the through hole, the speed of the spinning solution passing through the diverter plate is less than the speed passing through the feed port, so that the spinning solution gathers on the diverter plate. At this time, the spinning solution on the diverter plate applies pressure to the diverter plate, and the slide bar slides downward under the action of the pressure, and the reset part compresses and accumulates force, thereby increasing the distance between the diverter plate and the tank cover so as not to affect the normal feeding of the spinning solution; as the spinning solution flows down, the pressure on the diverter plate decreases, and at this time, the diverter plate can be reset upward under the drive of the reset part to avoid contact with the spinning solution in the static chamber below. It can be seen that the height of the diverter plate of the utility model is adjustable, and its height can be adaptively adjusted according to the weight of the spinning solution deposited thereon so as not to affect the normal feeding of the spinning solution.

[0019] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0020] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0021] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0022] like Figure 1 and Figure 2 As shown, this embodiment provides a spinning liquid degassing device, including a tank body 1, the interior of the tank body 1 forms a degassing chamber with an open top, and the bottom of the tank body 1 is provided with a discharge port 11, the discharge port 11 is located in the middle of the bottom wall of the degassing chamber, and the bottom wall of the degassing chamber gradually tilts upward in a direction away from the discharge port 11, so that the spinning liquid in the degassing chamber can be discharged smoothly. A support leg 12 is also provided at the bottom of the tank body 1, and the support leg 12 is fixedly connected to the tank body 1 for supporting the tank body 1.

[0023] A tank cover 2 is sealedly connected to the top of the tank body 1, and a feed port 21 is arranged in the middle of the tank cover 2. In addition, as in the prior art, a pressure gauge, a thermometer, a vacuum device, etc. (not shown in the figure) are also arranged on the tank cover 2 to monitor the temperature and pressure in the degassing chamber and to perform vacuum treatment on the degassing chamber to facilitate smooth degassing of the spinning solution.

[0024] A flow divider 3 is provided in the degassing chamber, and the flow divider 3 specifically includes a cylindrical bottom plate 31, and a cylindrical side plate 32 is provided on the outer edge of the bottom plate 31, and the outer wall of the side plate 32 is slidably matched with the side wall of the degassing chamber. In this embodiment, the flow divider 3 divides the degassing chamber into a buffer chamber 13 and a static chamber 14 from top to bottom, and a plurality of through holes 311 connecting the buffer chamber 13 and the static chamber 14 are evenly distributed on the circumference of the bottom plate 31.

[0025] The above-mentioned diverter plate 3 is slidably arranged in the degassing chamber, and can slide up and down driven by the lifting device. Specifically, the lifting device includes two slide bars 4 (in practice, the number of slide bars 4 can also be 3 or more, designed according to the size of the diverter plate 3), and the slide bars 4 are slidably penetrated on the tank cover 2, and a through hole 22 cooperating with the slide bar 4 is provided on the tank cover 2, and a sealing ring is embedded in the inner periphery of the through hole 22, so that the slide bar 4 and the through hole 22 are sealed and slidably matched. One end of the above-mentioned slide bar 4 extending into the tank body 1 is fixedly connected to the bottom plate 31. In this embodiment, the slide bar 4 is welded to the bottom plate 31.

[0026] Furthermore, a reset member 5 is sleeved on the outer periphery of the slide rod 4, and the reset member 5 is specifically a compression spring. The end of the slide rod 4 away from the tank cover 2 is threadedly connected to the limit head 41, and the two ends of the reset member 5 are respectively in contact with the tank cover 2 and the limit head 41. When the reset member 5 is in a free state, the diverter plate 3 is close to the tank cover 2. At this time, the distance between the limit head 41 and the tank cover 2 is smaller than the distance between the diverter plate 3 and the bottom wall of the degassing chamber.

[0027] In this embodiment, the spinning liquid flows into the buffer chamber from the feed port of the tank cover 2 and falls on the diverter plate 3. A plurality of through holes 311 are arranged on the diverter plate 3. The spinning liquid flows into the static chamber 14 through the through holes 311 under the action of gravity. After passing through the diverter plate 3, the spinning liquid is diverted into multiple streams, which increases its surface area, enables the bubbles in the spinning liquid to escape quickly, and improves the degassing effect. Since the inner diameter of the through hole 311 is much smaller than the inner diameter of the feed port 21, the speed at which the spinning liquid passes through the diverter plate 3 is lower than the speed at which the spinning liquid passes through the feed port 21, so that the spinning liquid gathers on the diverter plate 3. At this time, the spinning liquid on the diverter plate 3 applies pressure to the diverter plate 3, and the slide bar 4 slides downward under the action of the pressure, and the reset member 5 is compressed and accumulated, thereby increasing the distance between the diverter plate 3 and the tank cover 2 so as not to affect the normal feeding of the spinning liquid; as the spinning liquid flows downward, the pressure on the diverter plate 3 decreases. At this time, the diverter plate 3 can be reset upward driven by the reset member 5 to avoid contact with the spinning liquid in the static chamber 14 below.

[0028] Furthermore, the upper surface of the side plate 32 is gradually inclined downward in the direction away from the side wall of the degassing chamber, so as to guide the spinning liquid in the buffer chamber 13 to the bottom plate 31 to prevent the spinning liquid from gathering on the upper surface of the side plate 32. The setting of the side plate 32 can slide with the side wall of the degassing chamber and improve the strength of the diverter plate 3.

[0029] In addition, it should be noted that the tank body 1 of the present embodiment has a hollow interlayer, so that a heat-conducting medium can be introduced into the interlayer to heat the spinning solution in the degassing cavity and improve the degassing efficiency.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
