Description

Technical Field

[0001] The present application relates to the technical field of filling equipment, and in particular to a silica sol filling device. Background Art

[0002] Silica sol (English name: Silica solution) is a colloidal solution, odorless and non-toxic. Silica sol is a dispersion of nano-scale silicon dioxide particles in water or solvent. Silica sol can not only be used as a binder for refractory materials, but also has the advantages of strong bonding ability and high temperature resistance. Silica sol can also be used in coatings, papermaking, textiles and other industries.

[0003] The most commonly used preparation methods for silica sol include ion exchange, one-step hydrolysis of silicon powder, and silane hydrolysis. Foreign companies with more mature technology usually use ion exchange technology to prepare silica sol, while domestic companies usually use one-step hydrolysis of silicon powder. Compared with internationally renowned silica sol brands, the main disadvantages of domestic silica sol are high impurity content, no strict control of particle size, no strict detection of particle specific surface area, and low concentration of silicon dioxide.

[0004] At present, in the preparation process of silica sol, the materials for preparing silica sol are stirred and mixed in a container, and the silica sol is filled from the bottom of the container. For existing technical documents, reference may be made to patent documents such as publication numbers CN208119565U and CN216737563U.

[0005] However, when the production line is under regular maintenance, the denser materials in the mixed materials at the bottom of the silica sol preparation container will naturally settle, making the silica sol materials not mixed evenly, and the stirring device can hardly touch the materials at the bottom of the container. Therefore, when the production line resumes operation, the product quality of the silica sol is poor. How to ensure the product quality of silica sol after regular maintenance of the production line is an urgent problem to be solved in the industry. Utility Model Content

[0029] It should be understood that although the terms "first", "second", "third", etc. may be used in the present application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. In addition, the terms "vertical", "horizontal", "upper", "lower" and similar expressions used in the present application are positional relationships with reference to the accompanying drawings, and do not represent the expression of the only embodiment.

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] Reference Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application discloses a silica sol filling device. A silica sol filling device comprises a preparation container 1, a first stirring device 2 and a second stirring device 3. The preparation container 1 is a rectangular parallelepiped container, and the preparation container 1 is tilted. One end of the preparation container 1 is tilted upward and is a material input end 11, and the material input end 11 of the preparation container 1 is connected to a material input pipe 13. The other end of the preparation container 1 is tilted downward and is a silica sol output end 12, and the silica sol output end 12 of the preparation container 1 is connected to an output pipe 14.

[0032] Reference Figure 3 The first stirring device 2 includes a first rotating shaft 21 and a plurality of first stirring blades 22 connected to the first rotating shaft 21. The first rotating shaft 21 is rotatably connected to the top of the preparation container 1. The top of the preparation container 1 is provided with a first driving assembly 4 for driving the first rotating shaft 21 to rotate. The inclination direction of the first rotating shaft 21 is parallel to the inclination direction of the preparation container 1. The material input pipe 13 is located above the first stirring device 2, so that after the material is input from the material input pipe 13 into the preparation container 1, the first stirring device 2 can fully stir the material.

[0033] Reference Figure 3 The first driving assembly 4 includes a driving motor 41 and a reducer 42 . The output shaft of the driving motor 41 is coaxially fixed with the input shaft of the reducer 42 , and the output shaft of the reducer 42 is coaxially fixed with the first rotating shaft 21 .

[0034] Reference Figure 3The second stirring device 3 is arranged at the bottom of the preparation container 1, and the second stirring device 3 is located below the first stirring device 2. The second stirring device 3 includes a second rotating shaft 31 and a plurality of second stirring blades 32 connected to the second rotating shaft 31, and the second rotating shaft 31 is arranged horizontally, and the second rotating shaft 31 is rotatably connected to the preparation container 1. During the rotation of the second rotating shaft 31, the instantaneous movement direction of the bottom is toward the material input end 11, and the instantaneous movement direction of the top of the second rotating shaft 31 is toward the silica sol output end 12.

[0035] Reference Figure 3 In addition, the output pipe 14 is located above the second stirring device 3. It should be understood that the definition of "above" here includes that the height position of the output pipe 14 is located in the middle and upper position of the second stirring device 3, that is, the height position of the output pipe 14 is higher than the height position of the second rotating shaft 31. Therefore, after the silica sol material with a higher density naturally settles at the bottom of the preparation container 1, the second stirring device 3 can stir the material at the bottom of the preparation container 1 again, and the specific stirring direction can increase the flow path of the settled material from being stirred to being discharged from the output pipe 14, so as to ensure that the silica sol can have a higher mixing effect when it is output from the output pipe 14, thereby improving the molding quality of the silica sol.

[0036] Therefore, the second stirring device 3 serves the purpose of secondary stirring and mixing the silica sol material which is unevenly mixed due to natural sedimentation in the preparation container 1, thereby improving the mixing and molding quality of the silica sol.

[0037] Reference Figure 1 In order to facilitate driving the second stirring device 3 to work, a servo motor 5 for driving the second rotating shaft 31 to rotate is arranged outside the preparation container 1, and the servo motor 5 is fixed to the outside of the preparation container 1 by bolts.

[0038] Reference Figure 1 Since the preparation container 1 is arranged at an angle, in order to improve the stability of the preparation container 1, a support base 6 is arranged at the bottom of the preparation container 1, and the support base 6 includes a support plate 61 and a plurality of legs 62 connected to the bottom of the support plate 61. A positioning groove 611 with a triangular cross section is provided on the upper surface of the support plate 61. The positioning groove 611 has two inclined inner walls, and the two adjacent surfaces of the bottom of the preparation container 1 are respectively attached to the inner walls of the positioning groove 611. It should be understood that when the preparation container 1 is selected in other shapes, the positioning groove 611 can be a shape that matches the preparation container 1, so as to better support the bottom of the preparation container 1.

[0039] Reference Figure 1The upper surface of the support plate 61 is fixedly connected with a support column 63, which is vertically arranged, and the top of the support column 63 is supported on the lower side of the material input end 11 of the preparation container 1. The support plate 61, the support column 63 and the preparation container 1 form a triangular structure to achieve a relatively stable support for the preparation container 1.

[0040] Reference Figure 1 The upper surface of the support plate 61 is provided with a conveying groove 612, which is used for the conveying line of the silica sol bottles to pass through, and one end of the output tube 14 points to the conveying groove 612. Therefore, when the bottles pass through the conveying groove 612, the output tube 14 can fill the bottles in sequence, thereby improving the automation of the production line.

[0041] Reference Figure 1 and Figure 3 Since it is difficult for the second stirring device 3 to stir the naturally settled materials in the preparation container 1 to a high degree, it is necessary to regularly scrape the naturally settled materials to avoid the accumulation of more materials to hinder the rotation of the second stirring device 3. To this end, a scraper rod 7 is slidably provided at the bottom of the preparation container 1, and the scraper rod 7 is attached to the bottom inner wall of the preparation container 1. In this embodiment, the cross section of the scraper rod 7 is triangular, and the scraper rod 7 is attached to two adjacent inner walls of the bottom of the preparation container 1. The scraper rod 7 is located below the second stirring device 3, and a sliding drive member for driving the scraper rod 7 to slide is provided on the preparation container 1. The sliding drive member is a sliding cylinder 8, and the piston rod of the sliding cylinder 8 is fixedly connected to the scraper rod 7. The piston rod of the sliding cylinder 8 is slidably penetrated through the side wall of the preparation container 1. A sediment discharge pipe 15 is provided at the bottom of the preparation container 1, and the sliding direction of the scraper rod 7 points to the sediment discharge pipe 15. The scraper rod 7 is driven to slide by the sliding cylinder 8, so that the settled materials can be scraped regularly.

[0042] Reference Figure 4 and Figure 5 In order to control the opening or closing of the sediment discharge pipe 15, a control cylinder 17 is provided on the outside of the preparation container 1, and a closing plate 16 is fixed to the end of the piston rod of the control cylinder 17. The opening and closing of the sediment discharge pipe 15 is achieved by driving the closing plate 16 to slide.

[0043] The implementation principle of a silica sol filling device in the embodiment of the present application is as follows: the staff transports the material from the material input pipe 13 to the preparation container 1, and then the material is stirred by the first stirring device 2 for the first mixing. When the mixed material flows to the bottom of the preparation container 1, the second stirring device 3 performs secondary stirring, and the silica sol after the secondary stirring is discharged from the output pipe 14. The secondary stirring system consisting of the first stirring device 2 and the second stirring device 3 is provided to improve the degree of sufficient material mixing. In addition, when the production line is regularly maintained, the second stirring device 3 can prevent the silica sol at the bottom of the preparation container 1 from being discharged in the event of sedimentation, so that the second stirring device 3 has the effect of secondary stirring the material that has settled for a long time, which can improve the mixing quality after the silica sol has settled for a long time, thereby improving the product quality of the silica sol.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
