Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium silicate processing technology, specifically to a sodium silicate addition device with precise concentration control function. Background Technology
[0002] Sodium silicate solution is widely used in various industrial fields due to its adhesive properties, corrosion resistance, and gelling characteristics. However, precise adjustment of its concentration is crucial to meet the performance requirements of different applications. For example, in building construction, when used for waterproofing and leak sealing, a sodium silicate solution of approximately 50 Baume degrees is needed to utilize its rapid gelling properties to instantly seal leaks. When used as a concrete accelerator, it needs to be diluted to 30-40 Baume degrees to avoid excessively high concentrations that would cause the concrete to harden too quickly and become difficult to work with.
[0003] A novel sodium silicate addition device, disclosed in CN220003887U, includes a 40% sodium silicate storage tank, a sodium silicate dissolving tank, a sodium silicate addition metering tank, a primary power wave module, and a secondary power wave module. The sodium silicate dissolving tank and the sodium silicate addition metering tank are connected by pipes to form a loop. The bottom side of the 40% sodium silicate storage tank is connected to the top of the sodium silicate dissolving tank by a pipe, for transferring the solution from the 40% sodium silicate storage tank to the sodium silicate dissolving tank.
[0004] Current technologies have certain shortcomings in terms of the accuracy of concentration control and the uniformity of liquid mixing. This invention aims to provide a sodium silicate addition device with precise concentration control function to overcome the deficiencies of existing technologies. Utility Model Content
[0005] The purpose of this invention is to solve the above-mentioned problems by providing a sodium silicate addition device with precise concentration control function, in order to overcome the defects of the prior art, as detailed below.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] This utility model provides a sodium silicate addition device with precise concentration control function, including an addition tank and a digital display control panel. A central rotating shaft is rotatably arranged inside the addition tank. Several addition turntables with successively smaller outer diameters from top to bottom are arranged on the central rotating shaft. Each addition turntable has a liquid addition cavity and an opening near its outer side.
[0008] The central rotating shaft has liquid passages that are connected to the liquid filling cavities in each of the adding discs.
[0009] The addition tank is equipped with a liquid addition component for communicating with the liquid passage to provide water or sodium silicate liquid;
[0010] The addition tank is equipped with a rotary drive structure for driving the central shaft and the addition turntable to rotate.
[0011] Preferably, each added turntable is arranged on the central axis to form a frustum-shaped outline with the tip pointing downwards.
[0012] Preferably, each liquid filling cavity is provided with several connecting blocks for supporting the liquid filling turntable structure.
[0013] Preferably, the liquid addition assembly includes a main addition pipe disposed at the upper end of the addition tank, the lower end of which extends into the addition tank and is rotatably connected to the end of the central rotating shaft via a sealed rotary joint.
[0014] Preferably, the upper end of the main adding pipe is connected to two branch adding pipes, each of which is equipped with a first solenoid valve, and the output end of the digital display control panel is electrically connected to the input end of the first solenoid valve.
[0015] Preferably, an air pump is provided at the top of the main adding tube, and the output end of the digital display control panel is electrically connected to the input end of the air pump.
[0016] Preferably, the rotary drive structure uses a motor, which is fixedly mounted on the bottom side of the adding tank and its output shaft extends into the adding tank and is connected to the lower end of the central rotating shaft. The output end of the digital display control panel is electrically connected to the input end of the motor.
[0017] Preferably, a drain pipe is connected to one side of the bottom of the addition tank, and a second solenoid valve is installed on the drain pipe. The output end of the digital display control panel is electrically connected to the input end of the second solenoid valve.
[0018] Preferably, the bottom of the addition tank is connected to two or more columns, and the lower ends of the columns are fixedly connected to each other with bases.
[0019] Preferably, a pressure relief valve is provided on the upper side of the addition tank.
[0020] The beneficial effects are:
[0021] 1. By adding turntables arranged in a truncated cone shape with a larger top and a smaller bottom, the centrifugal force during rotation causes the liquid to be thrown out at high speed from the outer openings of different radii, forming a multi-layer radial spray effect that covers the entire cross-section of the tank, expanding the mixing range. The central rotating shaft drives the rotating rod to rotate and stir, which, together with the "atomization" effect of the spray, achieves three-dimensional mixing, greatly shortening the mixing time and significantly improving uniformity.
[0022] 2. The air pump at the top of the main addition pipe injects compressed air into the tank. On the one hand, it pushes the liquid through the liquid passage quickly, avoiding residual liquid in the liquid passage and improving the accuracy of concentration adjustment. On the other hand, it forms bubble disturbance, enhances the turbulence effect, and further accelerates the diffusion of solute. Attached Figure Description

The addition tank 1 is made of double-layer stainless steel. The inner layer is mirror-polished to effectively reduce liquid residue and facilitate cleaning and maintenance. The outer layer is equipped with an insulation layer to maintain a stable liquid temperature inside the tank, making it suitable for temperature-sensitive liquid addition scenarios. A central rotating shaft 14 is rotatably installed inside the addition tank 1. Several addition turntables 15 with progressively smaller outer diameters from top to bottom are installed on the central rotating shaft 14. The addition turntables 15 are made of aluminum alloy and have undergone anodizing treatment, forming a dense oxide film on the surface with a thickness of approximately 10-15 μm. Each adding turntable 15 has a liquid filling cavity 17 with an opening near its outer side; the central rotating shaft 14 has liquid passages that communicate with the liquid filling cavities 17 in each adding turntable 15; the adding tank 1 is provided with a liquid filling assembly for providing water or sodium silicate liquid through communication with the liquid passages; the adding tank 1 is provided with a rotary drive structure for driving the central rotating shaft 14 and the adding turntable 15 to rotate.
[0031] Each adding turntable 15 is arranged on the central rotating shaft 14, forming a frustum-shaped outline with the pointed end facing downwards. In practical applications, in terms of space utilization, the frustum-shaped structure fits the internal spatial structure of the adding tank 1, making full use of the longitudinal space inside the tank.
[0032] Each liquid filling cavity 17 is equipped with several connecting blocks 18 for supporting the structure of the liquid filling turntable 15.
[0033] This invention provides a specific liquid addition assembly, which includes a main addition pipe 3 disposed at the upper end of an addition tank 1. The lower end of the main addition pipe 3 extends into the addition tank 1 and is rotatably connected to the end of a central rotating shaft 14 via a sealed rotary joint 13. Two branch addition pipes 5 are connected to the upper end of the main addition pipe 3, each branch addition pipe 5 being equipped with a first solenoid valve 6. The output of a digital display control panel 10 is electrically connected to the input of the first solenoid valve 6. An air pump 4 is disposed at the top of the main addition pipe 3, and a pressure relief valve 11 is disposed on the upper side of the addition tank 1. During the process of the air pump 4 introducing gas into the addition tank 1, the pressure relief valve 11 can provide safe pressure relief. The output of the digital display control panel 10 is electrically connected to the input of the air pump 4. In practical applications, the liquid addition assembly achieves precise, flexible, and reliable liquid addition functions through the coordinated work of its components. The first solenoid valve 6 controls the liquid flow through different branch addition pipes 5, enabling selective addition and precise metering of various liquids. The air pump 4 provides pneumatic assistance, ensuring the liquid is fully delivered to the addition tank 1 for thorough mixing, and introduces gas into the addition tank 1 for better mixing. The main addition pipe 3 and the sealed rotary joint 13 ensure a stable supply of liquid from the outside to the central rotating shaft 14 inside the addition tank 1, and operate continuously during the rotation of the central rotating shaft 14. The entire liquid addition assembly can adapt to various liquid addition scenarios, efficiently and accurately adjusting the concentration whether it's quantitative addition of a single liquid or proportional mixing of multiple liquids.
[0034] The rotary drive structure uses motor 2, which is fixedly installed on the bottom side of the adding tank 1 and its output shaft extends into the inside of the adding tank 1 and is connected to the lower end of the central rotating shaft 14. The output end of the digital display control panel 10 is electrically connected to the input end of motor 2.

[0036] The bottom of the addition tank 1 is connected to two or more columns 8, and the lower ends of the columns 8 are fixedly connected to each other by a base 9.
[0037] Working principle:
[0038] When adjusting the concentration of the sodium silicate solution in the addition tank 1, one branch addition pipe 5 is used to add water to reduce the concentration of the sodium silicate solution, and the other branch addition pipe 5 is used to add high-concentration sodium silicate solution to increase the concentration. During the addition process, the liquid is added to the addition tank 1 sequentially through the main addition pipe 3, the central rotating shaft 14 (which is located inside the central rotating shaft 14), and the liquid addition cavities 17 of each addition disc 15. The outer diameter of each addition disc 15 is different, which can make the added liquid spray in four places in the addition tank 1. The central rotating shaft 14 drives the rotating rod 16 to rotate for stirring, thereby achieving rapid and thorough mixing of the liquid and uniform mixing. The concentration is controlled and adjusted by the concentration detection instruments set in the addition tank 1, such as a conductivity meter, refractometer, or ultrasonic concentration meter.
