Abstract
Description
Technical Field
[0001] The utility model relates to a pipeline system, and more particularly to a material mixing pipeline system with a circulation line. Background Art
[0002] In the production process of LCD screens, a series of mixed agents such as degumming liquid and diluent are needed to complete the corresponding processes. These mixed agents have different application scenarios, different application processes, and different effects, so they generally need to be mixed in a mixing tank in a specific proportion.
[0003] The existing mixing process using a mixing tank requires the use of a feed pipe to transport materials from the finished product tank. The distance from the storage tank area to the mixing tank in the workshop is long, which makes the feed pipeline long. If the weather is hot, the material in the feed pipeline will be mixed with gas, which will easily produce bubbles that affect the mixing quality and cause errors in the mass flow meter measurement during feeding. Moreover, when changing batches, due to the long feed pipe, the material of the previous batch will remain in the feed pipe. When entering the mixing tank again, it will enter the mixing tank together with the material of the previous batch, affecting the mixing quality.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

Each finished product tank 1 module is connected to the mixing tank 2 module through a circulation module. The number of finished product tank 1 modules and finished product filtering modules is consistent and one-to-one corresponding.
[0021] The finished product tank 1 module includes a finished product discharge end and a finished product circulation end, the mixing tank 2 module includes a mixing feed end, and the circulation module includes a feed pipe 3 and a circulation pipe 4. One end of the feed pipe 3 is connected to the finished product discharge end through a pump body, and the other end of the feed pipe 3 is connected to the mixing feed end. One end of the circulation pipe 4 is connected to the finished product circulation end, and the other end of the circulation pipe 4 is connected to the mixing feed end. By setting up the circulation module, when the mixing tank 2 module is discharged after mixing, the circulation module is used to circulate the materials in the pipeline that have not been transported to the mixing tank 2 module to the finished product tank 1 module for recollection. When the mixing tank 2 module is discharged, it is connected again, so that when loading, the finished product in the feed pipe 3 can be in a flowing state all the time, thereby avoiding bubbles mixed in the material in the pipeline, and the previous batch of finished products remaining in the feed pipe 3 and the circulation pipe 4 will be evenly mixed with the new batch of finished products, thereby ensuring the subsequent mixing quality.
[0022] The finished product tank 1 module also includes a finished product tank 1 and a finished product return end arranged on the finished product tank 1. The finished product discharge end and the finished product circulation end are arranged on the finished product tank 1. The mixing feed end is connected to the feed pipe 3 and the circulation pipe 4 respectively through a three-way valve; the finished product return end is connected to the finished product reflux valve, and the finished product reflux valve, one end of the finished product filtration module and the finished product discharge end are connected through a three-way valve T1; the finished product filtration module includes a first-level finished product filter 5 and a second-level finished product filter 6 that are interconnected. By setting up a multi-stage filter, multiple filtrations are performed to ensure the filtration effect. The first-level finished product filter 5 is away from the end of the second-level finished product filter 6 and is connected to the The three-way valve T1 is connected, the feed pipe 3 and the finished product filtration module are connected to the finished product filtration valve through the three-way valve T2, the finished product circulation end is connected to the finished product return pipe, and the finished product return pipe, the end of the circulation pipe 4 away from the mixing tank 2 module and the finished product filtration valve are connected through the three-way valve T3; by setting the finished product filtration module, the material in the finished product tank 1 preferentially passes through the finished product filtration module and then enters the feed pipe 3, and can be preliminarily filtered before entering the mixing tank 2, ensuring that the finished product particles are more uniform. When several kinds of filtered finished product particles enter the mixing tank 2 for mixing, the mixing efficiency can be guaranteed, and the best product quality can be guaranteed.
[0023] The mixing tank 2 module also includes a mixing tank 2, a mixing discharge end arranged on the mixing tank 2, a first mixing return end and a second mixing return end arranged on the mixing tank 2. The mixing feed end is arranged on the mixing tank 2, and the mixing discharge end is connected to the mixing filtration module through a pump body. The mixing filtration module includes a first-level mixing filter 7 and a second-level mixing filter 8 that are connected to each other. By setting a multi-stage filter, multiple filtrations are performed to ensure the filtering effect. The first-level mixing filter 7 is far away from the second-level mixing filter 8. One end is connected to the three-way valve T4, and the first mixing return end is connected to the mixing reflux valve through a pipeline. The mixing reflux valve is connected to the three-way valve T4 through a pipeline. The mixing discharge end is also connected to the pump body and is connected to the three-way valve T4 through a pipeline. By setting the mixing reflux valve and the first mixing return end, the mixed material can be refluxed multiple times before being loaded into the tank truck, thereby ensuring the viscosity of the mixed material. The consistency and mixing degree ensure the mixing efficiency, thereby ensuring the product quality; the secondary mixing filter 8 is connected to a three-way valve T5 at one end away from the primary mixing filter 7, and the remaining two ends of the three-way valve T5 are respectively connected to two one-way valves, one of which can be connected to the tank truck for loading, and the other one-way valve is connected to a mixing reflux pipe and is connected to the second mixing return end to achieve the reflux effect, which can prevent incomplete filtration and can return to the mixing tank 2 through the mixing reflux pipe and then be filtered through the mixing filter module chassis, making the filtration more sufficient and ensuring the product quality; the reflux pipe can also be connected to a three-way valve T6, and the tank truck can also use a one-way valve to connect to the three-way valve T6, which can avoid the tank truck itself from having material residues. The material residues can be squeezed back into the mixing tank 2 for mixing, and then enter the tank truck through the mixing filter module, further ensuring product quality.
[0024] Working principle: Control the three-way valve T1 in each finished product tank 1 module, and let the materials in several finished product tanks 1 pass through the corresponding finished product filtering module, and then transport them to the mixing tank 2 through the corresponding feeding pipe 3. Mixing is carried out in the mixing tank 2. After the mixing is completed, control the three-way valve T4, and the mixed materials pass through the mixing filtering module before being canned. Filtering through multiple groups of filtering modules ensures the uniformity of the materials, thereby ensuring the product quality.
[0025] When the mixed materials are being canned, the three-way valve at the mixing feed end of the mixing tank 2 is controlled to connect the feed pipe 3 with the circulation pipe 4, and the pump body in the finished product tank 1 module is kept running continuously, so that the finished product in the feed pipe 3 can always be in a flowing state during loading, thereby avoiding bubbles in the material in the pipeline, and the finished products of the previous batch remaining in the feed pipe 3 and the circulation pipe 4 will be evenly mixed with the finished products of the new batch, ensuring the mixing quality of the next batch.

These improvements and modifications should also be regarded as within the scope of protection of the present invention.
