Description

Technical Field

[0001] The invention relates to the technical field of plasticizer preparation, in particular to the technical field of a plasticizer mixing device. Background Art

[0002] Plasticizers are polymer material additives widely used in industrial production, also known as plasticizers. Any substance added to polymer materials to increase the plasticity of polymers is called a plasticizer. The use of plasticizers can improve the performance of polymer materials, reduce production costs, and improve production efficiency. It is an important type of chemical product additive. As an additive, it is widely used in plastic products, concrete, mud, cement, gypsum, cosmetics, cleaning agents and other materials.

[0003] Existing plasticizers are usually directly put into the reactor for stirring during mixing, so as to mix the materials. However, in actual operation, since the plasticizer is relatively viscous, the traditional mixing device cannot achieve the purpose of uniform stirring, resulting in insufficient mixing.

[0004] In order to solve the problems raised in the background technology, for example, application number CN201921595338.0 discloses a reaction kettle for uniformly mixing plasticizer solution, comprising a bottom plate, a kettle body and an upper cover, wherein the upper surface of the bottom plate is fixedly connected with a support column, and there are four support columns, which are arranged in a rectangular shape on the upper surface of the bottom plate, and the top of the support column is fixedly connected with the kettle body, and the top of the kettle body is provided with an upper cover, and the top of the kettle body is fixedly connected with a card block, and the bottom of the upper cover is provided with a card slot, and the first motor is started by controlling the switch, and then the first motor drives the stirring paddle to rotate through the rotating shaft, so that the plasticizer solution is mixed more evenly, and by setting a sampling valve, people can use the device to stir the plasticizer. Under the action of the sampling valve, it is convenient to take out the mixed solution and observe the mixing degree of the solution, so that people can use the device to stir the plasticizer more easily, but the structure has the following defects: Although the structure uses a motor to drive the stirring paddle to rotate so that the plasticizer can be mixed more evenly, the stirring paddle cannot contact the inner bottom wall of the mixing tank, so it cannot mix the raw materials accumulated on the bottom side of the mixing tank, and thus cannot fully stir the reaction raw materials, resulting in low mixing efficiency of the raw materials. In addition, since the materials on the bottom side are difficult to stir and mix, it is easy to reduce the quality of the finished product and easily cause blockage of the discharge port.

[0005] In order to solve the problems raised in the above-mentioned technology, for example, application number CN202122948113.2 discloses a raw material mixing device for plasticizer production, including a tank body, a first support cover is fixedly connected to the top of the tank body, an air supply assembly is provided on the outer surface of the tank body and the inner side of the first support cover, a second support cover is fixedly connected to the top of the first support cover, a driving gear is rotatably connected to the inner middle position of the second support cover, a driven gear is evenly meshed and connected to the outer side of the driving gear, and each transmission shaft is driven by a driving motor to rotate simultaneously, so that each mixing assembly cooperates with each other to stir the raw materials on the top side of the tank body, and the mixing assembly bulges the raw materials on the bottom side of the tank body by rotation, so as to promote the mixing of the deposited raw materials, and the discharge port can be prevented from being blocked by avoiding the deposition of the raw materials on the bottom side of the tank body, but the device still has the following defects: 1. The mixing components in the device cannot be moved and can only be stirred at a fixed position in the tank, which results in the raw materials accumulated on one side not being able to be stirred properly; 2. Since the plasticizer is relatively viscous, part of the raw materials will adhere to the inner wall of the tank during the mixing process. However, the structure lacks a scraping component, which makes it impossible to effectively scrape the raw materials on the inner wall of the tank, resulting in a waste of raw materials.
