Description

Technical Field

[0001] This utility model belongs to the field of cleaning technology for mixing tanks, and specifically relates to a cleaning system for epoxy resin dynamic mixing tanks. Background Technology

[0002] In the electrical engineering industry, epoxy resin is increasingly used as an insulating material. However, once the two main components, A and B, are mixed, a polymerization reaction occurs until curing. This reaction process can only be delayed, not reversed. Although the current static mixing method can greatly reduce or avoid waste caused by the inability to control the reaction process, solid resin systems, due to their many advantages, are widely used in production using dynamic mixing methods.

[0003] Because components A and B have a shelf life after mixing, the entire mixture must be used in the product within this period, and any remaining mixture must be discharged from the mixing container (called the final mixing tank). To ensure that the final mixing tank produces a mixture with the same lifespan and effectiveness for subsequent mixing, the tank must be cleaned before reuse. A common cleaning method is to add a cleaning solution to the final mixing tank, stir thoroughly, and then drain the cleaning solution. Previously, the cleaning results of this method were: 1) It was impossible to clean the top of the tank and the middle agitator shaft itself in a short time, resulting in residual mixture at the junction of the tank cover and the edge of the tank and the upper part of the agitator shaft. After a certain period of time, these residual mixtures solidified into solid impurities and fell into the tank, affecting the quality of the product and production; 2) The cleaning liquid could not be drained in a short time, leaving residue on the pipe wall or agitator, affecting the quality of subsequent products.

[0025] Example 2, please refer to Figure 1 and Figure 2 This utility model provides a cleaning system for an epoxy resin dynamic mixing tank, comprising: A cleaning system for an epoxy resin dynamic mixing tank includes: a cleaning fluid supply unit, a compressed air supply unit, a mixing tank, a drying device, and a recovery unit; the cleaning fluid supply unit is connected to the mixing tank, the drying device is installed on the mixing tank, the compressed air supply unit is connected to the drying device, and the bottom of the mixing tank is connected to the recovery unit.

[0026] The drying device includes an inner ring nozzle 1 and an outer ring nozzle 2, both of which are mounted on the end cap of the mixing tank.

[0027] The inner ring nozzle 1 and the outer ring nozzle 2 are arranged in a ring on the end cover of the mixing tank. The inner ring nozzle 1 faces the stirring shaft, and the outer ring nozzle 2 faces the tank wall of the mixing tank.

[0028] The inner ring nozzles are distributed in a circle around the central axis, with a quantity of at least 3. The nozzles can be fan-shaped nozzles or rotating nozzles. The outer ring nozzles are distributed in a circle around the central axis, with a quantity of at least 3. They are different from the inner ring nozzles by a certain phase angle. The outer ring nozzles can be fan-shaped nozzles or rotating nozzles.

[0029] The inner ring nozzle sprays cleaning agent onto the circumferential wall of the final mixing tank to clean the tank body and top cover. The outer nozzles spray cleaning agent onto the central mixing shaft of the final mixing tank to clean the mixing shaft and the top cover.

[0030] The cleaning fluid supply unit includes a compressed air tank, a first solenoid valve 3, and a second solenoid valve 4. The compressed air tank is connected to the inner ring nozzle 1 and the outer ring nozzle 2 through pipelines, and the first solenoid valve 3 and the second solenoid valve 4 are respectively installed on the pipelines.

[0031] The cleaning fluid supply unit includes a raw material tank 5 and a first diaphragm pump 6. The raw material tank 5 is connected to a mixing tank through a pipeline, and the first diaphragm pump 6 is installed on the pipeline. The raw material tank 5 contains cleaning fluid.

[0032] A cleaning fluid filter 7 is also installed on the pipeline on the side of the first diaphragm pump 6; an electric two-way valve 8 is installed near the mixing tank on the pipeline.

[0033] The recycling unit includes a funnel 10, a second diaphragm pump 9, and a sedimentation tank 11. The funnel 10 is located at the bottom outlet of the mixing tank, and the bottom of the funnel 10 is connected to the sedimentation tank 11 through a pipeline. The second diaphragm pump 9 is installed on the pipeline.

[0034] A first electro-hydraulic three-way valve 13 and a second electro-hydraulic three-way valve 14 are respectively installed on the pipelines on both sides of the second diaphragm pump 9. One end of the first electro-hydraulic three-way valve 13 is connected to the raw material tank, one end is connected to the second diaphragm pump 9, and the other end is connected to the sedimentation tank. One end of the second electro-hydraulic three-way valve 14 is connected to the funnel, one end is connected to the second diaphragm pump 9, and the other end is connected to the sedimentation tank.

[0035] A pouring valve 12 is installed at the bottom outlet of the mixing tank.

[0036] Working principle: Once the pouring process is complete, immediately close the pouring valve below the final mixing tank, manually rotate the cleaning fluid funnel to below the pouring nozzle, and then start the cleaning program.

[0037] 1. Pump the cleaning solution in the raw material tank into the final mixing tank through the first diaphragm pump 6 (after passing through the cleaning solution filter 7); 2. Start the agitator to allow the cleaning solution to thoroughly clean the pipe wall and the agitator itself during agitation; 3. After stirring for 5-10 minutes (depending on the size of the tank), open pouring valve 12 to drain the cleaning solution; 4. By alternately opening the compressed air intake valves, compressed air is forced to dry the residual cleaning liquid on the pipe wall / top cover and top cover / stirring shaft through the inner / outer ring nozzles, shortening the dripping time; 5. After blowing for 3-5 minutes (depending on the tank structure), stop blowing and confirm that there is no residual cleaning fluid in the tank, then close the pouring valve 12.

[0038] The cleaning process is complete. However, the treatment of the cleaning fluid outside the tank continues. The second diaphragm pump 9 outside the tank, along with the first electro-pneumatic three-way valve 13 and the second electro-pneumatic three-way valve 14, work together to control the liquid levels in the sedimentation tank and the raw material tank.

[0039] When the cleaning fluid flows out through the funnel, a diaphragm pump is used to force it out in order to accelerate the flow rate. That is, the cleaning fluid flows along passage 1. When the cleaning fluid is discharged into the sedimentation tank, if the liquid level in the sedimentation tank reaches the high level, the second diaphragm pump 9 is also started. The first electro-pneumatic three-way valve 13 and the second electro-pneumatic three-way valve 14 are activated to pump the cleaning fluid from the sedimentation tank into the raw material tank along passage 2 until the liquid level probe of the raw material tank alarms and the discharge stops.

[0040] The entire cleaning process can be automated with a single click, improving production efficiency and avoiding the dangers of high temperatures during operation.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
