Description

Technical Field

[0001] The utility model relates to the technical field of viscose fiber production, in particular to an online cleaning and recovery system for KKF filter cavity glue. Background Art

[0002] In viscose production systems, KKF filters are widely used due to their numerous advantages, including high filtration capacity, small footprint, automatic backwashing, and low failure rate. However, during disassembly for cleaning and filter replacement, the original online recovery system failed to completely dilute the viscose in the KKF filter cavity. This process generated a large amount of impurities containing viscose, as well as high-alkali, high-density impurities that were difficult to flow, which adhered to the filter cavity and could not be properly discharged. They had to be flushed away with large amounts of water, causing the viscose to be discharged outside the system along with the diluted glue, and even onto the ground.

[0003] Therefore, some glue or diluted alkali solution will remain in the filter cavity, resulting in incomplete cleaning. Utility Model Content

[0004] In view of the deficiency of the above-mentioned prior art that cleaning the viscose in the filter cavity easily causes environmental pollution, the utility model provides a KKF filter cavity glue online cleaning and recovery system, which can recover the viscose in the filter cavity more thoroughly and has a better cleaning effect.

An air source pipe for flushing compressed air is connected between the flow pipe a and the waste rubber outlet of the KKF filter; during cleaning, the viscose inlet pipe, the viscose outlet pipe and the waste rubber outlet pipe are closed, and the return pipe a and the return pipe b are opened. The alkali liquid in the alkali tank is input into the KKF filter through the alkali inlet pipe under the action of the alkali pump, and the dilution liquid in the KKF filter cavity is returned to the alkali tank through the return pipe a and the return pipe b under the action of compressed air.

[0013] Furthermore, the alkali inlet pipeline is a steel wire hose between the alkali solution feed valve and the online cleaning feed valve.

[0014] In summary, the present invention has the following beneficial effects:

[0015] (1) The filter is connected to the alkali tank through a pipeline, wherein the viscose inlet pipeline of the filter is connected to the alkali pipeline, and the alkali liquid in the alkali tank is transported to the filter to dilute the viscose in the cavity, and the diluted glue is transported to the alkali tank through the reflux pipeline connected to the filter sampling valve and the waste glue outlet pipeline.

[0019] The present invention will be further described in detail below with reference to the embodiments.

[0020] Example 1:

[0021] When implementing: Figure 1As shown, a KKF filter 1 cavity glue online cleaning and recovery system includes a KKF filter 1 and an alkali tank 2, the KKF filter 1 is connected to a waste glue outlet pipe 11, a viscose inlet pipe 5 and a viscose outlet pipe 12, the waste glue outlet pipe 11 is connected to a reflux pipe a3, the filter sampling valve is connected to a reflux pipe b4, the reflux pipe a3 and the reflux pipe b4 are both connected to the alkali tank 2, an alkali inlet pipe 6 is connected between the alkali tank 2 and the viscose inlet pipe 5, the waste glue outlet pipe 11 of the KKF filter 1 is located between the reflux pipe a3 and the waste glue outlet of the KKF filter 1 During cleaning, the viscose inlet pipe 5, the viscose outlet pipe 12 and the waste rubber outlet pipe 11 are closed, and the reflux pipe a3 and the reflux pipe b4 are opened. The alkali solution in the alkali tank 2 is input into the KKF filter 1 through the alkali inlet pipe 6 under the action of the alkali pump 61, and the dilution liquid in the cavity of the KKF filter 1 returns to the alkali tank 2 through the reflux pipe a3 and the reflux pipe b4 under the action of compressed air. The KKF filter 1 and the alkali tank 2 form a circulation path for diluting and cleaning the viscose in the cavity of the KKF filter 1 through the alkali inlet pipe 6, the reflux pipe a3 and the reflux pipe b4.

[0022] Since the alkali liquid in the filter is difficult to be completely recovered, it can only be discharged to the ground after the filter end cover is opened. The alkali liquid in the filter cavity can be completely recovered by compressed air.

[0023] By connecting the pipelines and controlling the valves between the KKF filter 1 and the alkali tank 2, the alkali inlet pipeline 6, the return pipeline a3 and the return pipeline b4 are connected to the original pipelines respectively, and the flow of the alkali solution and the cleaning liquid is controlled to achieve dilution and cleaning of the viscose in the cavity of the KKF filter 1.

[0024] The reflux pipe b4 is connected to the filter sampling valve at the bottom of the KKF filter 1. This area is prone to leaving glue or diluent, so the filter sampling valve connected to the reflux pipe b4 can effectively clean the filter cavity and the glue or diluent in this area of ​​the filter.

[0025] During implementation, the glue inlet pipe 5 is equipped with a glue inlet valve 51, the KKF filter 1 is equipped with a filter outlet sampling valve 121, and the waste glue outlet pipe 11 is equipped with a waste glue valve 111.

The return pipe a3 is located between the waste glue valve 111 and the waste glue outlet of the KKF filter 1. The return pipe b4 is located between the outlet sampling valve of the KKF filter 1. During cleaning, the glue inlet valve 51, glue outlet valves 121, waste glue valve 111, and alkali circulation valve 91 need to be closed to form a circulation line between the alkali tank 2 and the KKF filter 1. This circulates and dilutes the glue in the filter cavity, ensuring a more thorough cleaning of the KKF filter 1 cavity.

[0026] During implementation, the waste rubber outlet pipe 11 of the KKF filter 1 is located between the return pipe a3 and the waste rubber outlet of the KKF filter 1 and is connected to the air source pipe 7 for flushing in compressed air.

After the piston of the KKF filter 1 is moved to the middle position, the filter sampling valve and the compressed air on / off valve 71 (pressure 3.5 kg) are opened.

After the cleaning is completed, the reflux pipe a3, the reflux pipe b4 and the alkali inlet pipe 6 are closed, and the alkali solution switching valve 651 is opened to pump the diluted alkali solution in the alkali tank 2 into the waste glue dilution system 8. After the diluted alkali solution in the alkali tank 2 is completely pumped out, the reflux pipe b4 is opened, and the compressed air switch valve 71 is opened to press the diluted alkali solution in the filter cavity into the alkali tank 2. The alkali solution circulation valve 91 can also be opened to use the reflux pipe b4 to directly press the alkali solution in the cavity into the waste glue dilution system 8.

[0030] During implementation, the alkali inlet pipeline 6 is equipped with an alkali pump 61, an alkali pump outlet valve 62, and an online cleaning feed valve 63 along the delivery direction. The inlet end of the reflux pipeline a3 is equipped with an online cleaning reflux valve a31, and the inlet end of the reflux pipeline b4 is equipped with an online cleaning reflux valve b41. The alkali pump 61, alkali pump outlet valve 62, and online cleaning feed valve 63 are configured to transport and control the inflow and outflow of alkali solution to maintain the cleaning process.
