Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin film production technology, and specifically to a hydrophilic film raw material stirring device. Background Technology
[0002] Hydrophilic membranes are a type of ultrafiltration membrane that can filter out some harmful substances in water. These membranes can filter water under very low pressure. Ultrafiltration membranes have a wide range of industrial applications and have become one of the new chemical unit operations, used for the separation, concentration, and purification of biological products, pharmaceutical products, and the food industry.
[0003] When producing hydrophilic membranes, the raw materials need to be mixed in proportion. However, traditional mixing and stirring devices usually pour the raw materials into the mixing tank together for mixing, which results in uneven mixing of the base liquid and other particulate materials. Even if it is to make the mixture uniform, the mixing time will be deliberately extended, which reduces the production efficiency. Utility Model Content

[0022] The following is a description of the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.
[0023] Example 1
[0024] A hydrophilic membrane raw material mixing device includes: a mixing vessel 1, wherein the mixing vessel 1 is provided with a feed pipe 11, a feeding port 12, and a discharge pipe 13 at its upper and lower ends, and a mixing mechanism 2 is provided inside; a feeding mechanism 3 is provided on the side end of the feeding port 12; the mixing mechanism 2 includes a mixing shaft 21 rotatably disposed in the mixing vessel 1, a mixing blade 22 fixedly disposed in the mixing shaft 21, and a drive motor 23 disposed at the lower end of the mixing vessel 1; the lower end of the mixing shaft 21 passes through the lower wall 3 of the mixing vessel 1 and is connected to the output end of the drive motor 23; and the feeding mechanism 3 is provided inside the mixing vessel 1. 3 includes an installation plate 31 inclinedly disposed on the upper end of the mixing vessel 1, a rotating base plate 32 fixedly disposed on the installation plate 31, a feeding cylinder 33 rotatably disposed within the rotating base plate 32, a placement plate 34 fixedly disposed on the installation plate 31, a feeding motor 35 disposed on the placement plate 34, and a feeding pipe 36. The feeding cylinder 33 has a discharge port 331 on the side away from the installation plate 31 and a transmission tooth 332 on its outer side. The output end of the feeding motor 35 is fixedly provided with a drive tooth 351, and the drive tooth 351 meshes with the transmission tooth 332.
[0025] like Figures 1-2 As shown, in practical application, the base liquid is first injected into the mixing tank 1 through the feed pipe 11. Then, the drive motor 23 is started, and the drive motor 23 drives the stirring shaft 21 and stirring blades 22 to rotate, so as to uniformly stir the base liquid and ensure that the base liquid is fully mixed in the mixing tank 1, so as to prepare for the subsequent mixing of additives.
[0026] Simultaneously, granular additives are fed into the feeding cylinder 33 through the feeding pipe 36. The feeding motor 35 drives the feeding cylinder 33 to rotate, causing the granular additives to be intermittently injected into the mixing tank 1 from the discharge port 331 under the action of gravity during the rotation of the feeding cylinder 33. Through the intermittent feeding method, the granular material can be evenly dispersed in the base liquid and fully mixed with the base liquid. This not only makes the granular material and the base liquid more thoroughly mixed, but also reduces the mixing time to a certain extent, improves the efficiency of the entire processing and production, and ensures the uniformity of mixing and the improvement of production efficiency.
[0027] As a further preferred embodiment, a thermostatic tube 41 is arranged around the outside of the stirring vessel 1, and a heat insulation layer 42 is arranged around the outside of the thermostatic tube 41.
[0028] Specifically, the thermostatic tube 41 effectively controls the temperature inside the mixing vessel 1 by circulating cooling or heating medium, ensuring that the base liquid and additives are always kept within the optimal reaction temperature range during the mixing process; the insulation layer 42 further reduces heat loss and energy consumption, while preventing operators from being burned or frostbitten due to contact with the outer wall of the mixing vessel 1, thus improving the safety of the equipment.
[0029] As a further preferred embodiment, a circulation pipe 51 and a circulation pump 52 are provided on the side wall of the stirring vessel 1, and the upper and lower ends of the circulation pipe 51 are respectively connected to the upper and lower pipes on the side wall of the stirring vessel 1.
[0030] Specifically, the liquid in the stirred tank 1 is driven to circulate through the circulation pipe 51 and the circulation pump 52 to ensure that the base liquid and additives are always evenly distributed during the mixing process, thereby further improving the mixing efficiency and quality.
[0031] As a further preferred embodiment, a filter screen 61 is provided at the inlet of the circulation pipe 51 at the lower end. During the circulation process, the filter screen 61 prevents impurities from entering the circulation system, thus avoiding clogging of the circulation pipe 51 or damage to the circulation pump 52.
[0032] As a further preferred embodiment, a baffle 62 is provided at the upper end of the feeding port 12. The baffle 62 is inclined and the inclination direction of the baffle 62 is opposite to the inclination direction of the mounting plate 31. By guiding the flow direction of the granular additive, it ensures that the material can enter the feeding cylinder 33 evenly and reduces the accumulation or overflow of material at the feeding port 12.
[0033] As a further preferred embodiment, the bottom of the mixing vessel 1 is inclined toward the feed pipe 13.
[0034] As a further preferred embodiment, a scraper 63 is fixed in the middle of the stirring shaft 21 and a material distribution plate 64 is provided at the upper end, and the scraper 63 abuts against the inner wall of the stirring vessel 1.
[0035] Specifically, the scraper 63 is in close contact with the inner wall of the mixing vessel 1, and can continuously scrape the inner wall during the mixing process to prevent material adhesion and ensure the cleanliness of the inner wall of the mixing vessel 1; when the granular material enters the mixing vessel 1, it collides with the distribution plate 64, and the distribution plate 64 disperses the granular material into the base liquid to avoid local concentrations that are too high or too low, thereby further improving the uniformity and efficiency of mixing.
[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
