Description

Technical Field

[0001] The utility model relates to the technical field of viscose fiber production, in particular to an online cleaning system for a degassing device. Background Art

[0002] In viscose production systems, degassing is crucial. Poor degassing can easily lead to the formation of air bubbles, which directly impacts the fiber's strength and quality. Furthermore, the viscose adhering to the walls of the degassing barrel gradually ages during the maturation process, forming a rubber film. This not only threatens the degassing effect but can also be carried into subsequent production steps after the degassing barrel as the process progresses, adversely affecting the spinning process. Therefore, in daily management, to address this issue, it is often necessary to regularly open the bottom valve to drain the rubber film. Furthermore, residual viscose in the pipeline is flushed out of the system by the rubber film in the degassing barrel. This process results in the viscose being directly discharged from the system, posing a potential threat to environmental protection.

[0003] This system not only requires a large amount of produced water for flushing, but also causes the viscose to be directly discharged outside the system, which has certain negative impacts on environmental protection and resource management. Therefore, for the degassing process in the viscose production process, it is necessary to seek more environmentally friendly and efficient solutions to reduce the adverse impact on the environment and improve production efficiency and product quality. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an online cleaning system for a degassing device which reduces the use of a large amount of production water for flushing and recycles the viscose.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: an online cleaning system for a degassing device, comprising a degassing barrel, a viscose feed pipe for injecting viscose connected to the top of the degassing barrel, and a viscose discharge pipe connected to the bottom of the degassing barrel, a discharge pump and a discharge pump outlet valve being provided on the viscose discharge pipe, a recovery pipe being connected between the discharge pump outlet valve and the discharge pump, the recovery pipe being connected to a recovery tank, the discharge pipe being provided with a flushing pipe for injecting alkali solution into the discharge pipe between the outlet end of the degassing barrel and the discharge pump, and an alkali valve being provided on the flushing pipe.

[0006] Furthermore, the recovery tank is connected to an alkali solution feeding pipe.

[0007] Furthermore, the recovery tank is connected to the waste rubber dilution unit through a delivery pipeline, and a delivery valve and a delivery pump are provided on the delivery pipeline.

[0008] Furthermore, the flushing pipe is a flushing pipe into which alkaline solution with a concentration of 22g / L is injected.

[0009] Furthermore, a discharge pump inlet valve is provided between the discharge pump and the flushing pipe.

[0010] In summary, the present invention has the following beneficial effects:

[0011] (1) The viscose discharge pipe at the bottom of the degassing barrel is connected to the flushing pipe. A certain proportion of alkali solution is injected into the viscose discharge pipe through the flushing pipe, and the alkali solution and viscose are input into the recovery tank along the pipeline. Therefore, the viscose in the pipeline can be recycled before flushing the degassing barrel, thereby effectively utilizing the originally discarded viscose and saving costs.

[0012] (2) Flushing the degassing barrel and treating the glue in the pipe separately can avoid using a large amount of water to flush the degassing barrel and the pipe at the same time. Since the glue in the pipe can be collected and used in the waste glue dilution system when it is treated separately, it can save production water and the glue will not be discharged with the flushing water, which can reduce the pressure of environmental protection treatment and reduce the cost of environmental protection treatment.

DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the embodiments.

[0016] The viscose adheres to the wall of the degassing barrel 1 and gradually forms a rubber film over time, which not only threatens the degassing effect, but may also be brought into subsequent production links as the process progresses, causing adverse effects on the spinning process and further aggravating the difficulty and cost pressure of production management.

[0017] In the viscose production system, the degassing device needs to be cleaned to improve the degassing efficiency and effectively utilize the waste viscose, so as to save costs and achieve sustainable utilization of resources. This system includes components such as a degassing barrel 1, a viscose feed pipe 2, a viscose discharge pipe 3, a discharge pump 4, a discharge pump outlet valve 5, a recovery pipe 6, a recovery tank 7, and a flushing pipe 8. Specifically, Figure 1As shown, the top of the degassing barrel 1 is connected to a viscose feed pipe 2 for injecting viscose, and the bottom of the degassing barrel 1 is connected to a viscose discharge pipe 3, a discharge pump 4 and a discharge pump outlet valve 5 are arranged on the viscose discharge pipe 3, a recovery pipe 6 is connected between the discharge pump outlet valve 5 and the discharge pump 4, and the recovery pipe 6 is connected to a recovery tank 7, and a flushing pipe 8 for injecting alkali solution into the discharge pipe is arranged between the outlet end of the degassing barrel 1 and the discharge pump 4, and an alkali valve 9 is provided on the flushing pipe 8.

[0018] The viscose discharge pipe 3 at the bottom of the degassing barrel 1 is connected to the flushing pipe 8. Before cleaning the degassing device, the viscose in the viscose discharge pipe 3 is cleaned first, that is, the viscose discharge pipe 3 section between the outlet end of the degassing barrel 1 and the discharge pump 4 is connected to the flushing pipe 8 at the end of the viscose discharge pipe 3 close to the degassing barrel 1. A certain proportion of alkali solution is injected into the viscose discharge pipe 3 through the flushing pipe 8, and the alkali solution and viscose are input into the recovery tank 7 along the pipeline. Therefore, the viscose in the pipeline can be recycled before flushing the degassing barrel 1, thereby effectively utilizing the originally discarded viscose and saving costs.

[0019] During implementation, the viscose in the recovery tank 7 is diluted. The recovery tank 7 is connected to an alkali solution feeding pipe. Alkali solution is added to the recovery tank 7 in proportion, and alkali solution is added to the recovery tank 7 in a ratio of viscose to alkali solution of 1:6~1:10. Alkali solution is added to the recovery tank 7 in proportion to ensure that the ratio of viscose to alkali solution is within the range of 1:6~1:10 to achieve the best cleaning effect.

[0020] Furthermore, the recovery tank 7 is connected to the waste rubber dilution unit 10 through a delivery pipe 11, and the delivery pipe 11 is provided with a delivery valve 12 and a delivery pump 13 to pump the mixed liquid to the waste rubber dilution system for use.

[0021] Furthermore, the flushing pipe 8 is a flushing pipe into which alkaline solution with a concentration of 22 g / L is injected. That is, when a certain proportion of alkaline solution is injected into the viscose discharge pipe 3 through the flushing pipe 8, the concentration of the alkaline solution is 22 g / L.

[0022] Furthermore, an inlet valve is provided between the discharge pump 4 and the flushing pipe 8 .

[0023] Furthermore, during the alkali solution injection process, the discharge pump 4 outputs the alkali solution and the viscose, and the discharge pump 4 can be turned on at 1 / 4 of the full power to ensure the stability and fluidity of the mixture.

[0024] Through the implementation of this technical solution, the efficiency and cleanliness of the degassing process can be effectively improved, the recycling of waste viscose can be achieved, production costs can be reduced, and the impact on the environment can be minimized.

[0025] After cleaning the discharge pipe, flush the continuous degassing barrel according to the original process. The original specific cleaning method is as follows: stop the feed pump, close the feed pump outlet valve, and wait until the viscose in the continuous degassing barrel is completely discharged. Then stop the discharge pump 4, close the discharge pump inlet valve 14 and the discharge pump outlet valve 5, close the vacuum pump valve, and break the vacuum to exhaust. After the degassing barrel 1 is completely exhausted, open the manhole and flush the rubber on the barrel wall. After rinsing, remove the inlet blind plate of the degassing barrel 1 discharge pump 4, open the degassing barrel 1 discharge pump inlet valve 14, discharge the rubber in the pipe to the ground, and filter the rubber with a basket.

[0026] In this way, the flushing of the degassing barrel 1 and the separate treatment of the viscose in the pipeline can avoid the use of a large amount of water to flush the degassing barrel 1 and the pipeline at the same time. Since the viscose in the pipeline can be collected and used in the waste glue dilution system when it is treated separately, production water can be saved, and the viscose will not be discharged with the flushing water, which can reduce the pressure of environmental protection treatment and reduce the cost of environmental protection treatment.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
