Technical Field
[0001] The utility model relates to the technical field of sodium silicate preparation, in particular to a solution impurity removal device for preparing sodium silicate by a melting method. Background Art
[0002] Sodium silicate is an important chemical raw material, widely used in glass, detergent, paper, dye and other industries. Sodium silicate is usually made by melting, mixing sodium silicate with other chemicals such as soda ash (Na2CO3) and quartz sand (SiO2) in a certain proportion, and then melting at high temperature. The high-temperature molten product flows out from the outlet of the kiln, and is pressed into blocks or quenched into particles by the rollers on the mold. If liquid products need to be produced, high-temperature dissolution or high-temperature and high-pressure dissolution is required, and impurities are removed by static precipitation. The upper clear liquid is concentrated to obtain liquid water glass, that is, an aqueous solution of sodium silicate, commonly known as water glass. This liquid water glass has a certain viscosity and can be used as a mineral binder, and has a wide range of uses.
[0003] The existing solution impurity removal equipment for preparing sodium silicate usually uses extraction to discharge the upper clarified liquid after standing and clarifying. The extraction process will cause disturbance and make some precipitated impurities at the bottom float, affecting the purity of the extracted solution. After the upper clarified liquid is discharged, the precipitated impurities at the bottom are not easy to clean up, which is easy to affect the subsequent standing and clarifying and impurity removal work, reducing the impurity removal effect. To this end, we propose a solution impurity removal equipment for preparing sodium silicate by melting method. Utility Model Content

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-4 The utility model provides a technical solution: a solution impurity removal device for preparing sodium silicate by a melting method, comprising a cylindrical impurity removal kettle 1, and a plurality of pillars 2 are evenly arranged on the lower surface of the impurity removal kettle 1 for supporting it.
[0019] A precipitation area 5 for precipitating impurities is provided at the lower part of the impurity removal kettle 1, and a plurality of drain pipes 6 are evenly provided on the outer surface of the impurity removal kettle 1, and the plurality of drain pipes 6 are connected in parallel with the external drainage main pipe. The plurality of drain pipes 6 are arranged at different heights on the side surface of the impurity removal kettle 1, and each drain pipe 6 is provided with a drain pipe valve 7, and the drain pipe valve 7 can be selected as a commonly used solenoid valve. The dissolved solution is put into the impurity removal kettle 1 for static clarification, and the impurities in the solution are precipitated to the precipitation area 5 at the bottom. After the static clarification is completed, the staff opens the drain pipe valve 7 on the drain pipe 6 at a certain height from the precipitated impurities according to the height of the precipitated impurities, and discharges the upper clear liquid into the collection device through the drain pipe 6 and the external drainage main pipe, and then opens the drain pipe valve 7 on the lowest drain pipe 6 closest to the precipitated impurities, and discharges the solution that may be mixed with impurities at the bottom into another collection device, and removes impurities again to improve the purity of the sodium silicate solution, ensure the impurity removal effect and product quality, etc.
[0020] The preferred technical solution is to open an observation window on the side surface of the impurity removal kettle 1, and the observation window extends to the precipitation area, so that the staff can check the height of the precipitated impurities in the impurity removal kettle 1 through the observation window, thereby opening the drain pipe valve 7 at the corresponding height to discharge the upper clear liquid and complete the impurity removal work of the sodium silicate solution.
[0021] Optionally, scale lines can be provided on the observation window, and the staff can judge the height of the precipitated impurities more accurately through the scale lines, thereby quickly judging which drain pipe valve 7 needs to be opened, which is more convenient to use.
[0022] The preferred technical solution is that the drain pipe 6 is evenly arranged on the side surface of the impurity removal kettle 1 in a spiral ascending shape, and the pipe openings of adjacent drain pipes 6 have overlapping parts in height, so as to discharge as much upper clear liquid as possible; at least two groups of drain pipes 6 and drain pipe valves 7 are provided, and at least two groups of drain pipes 6 are evenly arranged on spiral lines parallel to each other. The part occupied by all drain pipes 6 on the outside of the impurity removal kettle 1 is less than a quarter of a circle, preferably one-fifth of a circle or one-sixth of a circle, so as to avoid the ends of each drain pipe 6 being too far apart, resulting in the entire pipeline being too complicated after being connected in parallel to the drain main pipe, and facilitating maintenance and overhaul operations.
[0023] The drainage main pipe may include at least two spiral pipes, and the spiral pipes connect a group of drainage pipes 6 in parallel. All the spiral pipes are then connected in parallel to a unified liquid outlet pipe, which is connected to an external collection device.
[0024] The precipitation zone 5 is a cone with a larger top and a smaller bottom. A drainage pipe 3 is fixedly arranged at the bottom center of the precipitation zone 5. A drainage pipe valve 4 is arranged on the drainage pipe 3. A cleaning device for cleaning the precipitation zone 5 is arranged above the impurity removal kettle 1. After discharging the upper clear liquid, the drainage pipe valve 4 is opened to discharge the precipitated impurities in the precipitation zone 5 through the drainage pipe 3. Then, the cleaning device arranged above the impurity removal kettle 1 is moved to the precipitation zone 5 to clean the precipitated impurities remaining therein, so as to avoid the residual impurities from affecting the subsequent static clarification and impurity removal work, thereby further improving the impurity removal effect of the sodium silicate solution.
[0025] One of the specific technical solutions is that the cleaning device includes a hydraulic cylinder 13 installed on the lower side of the external mounting frame, a driving motor 12 is installed inside the lower side of the movable end of the hydraulic cylinder 13, the output shaft of the driving motor 12 passes through the lower surface of the movable end of the hydraulic cylinder 13 and is fixedly connected to the connecting block 11, the side surface of the connecting block 11 is provided with a cleaning vertical plate 9 corresponding to the impurity discharge pipe 3, the upper surface of the cleaning vertical plate 9 is fixedly provided with a cleaning inclined plate 8 corresponding to the sedimentation area 5, the outer side of the cleaning inclined plate 8 is an arc matching the sedimentation area 5, and the sedimentation area 5 is discharged through the impurity discharge pipe 3. After the precipitated impurities are discharged, the staff operates the external control switch to turn on the hydraulic cylinder 13, and the hydraulic cylinder 13 drives the driving motor 12 and the connecting block 11 to move downward into the sedimentation area 5, so that the cleaning vertical plate 9 is in contact with the impurity discharge pipe 3, and the cleaning inclined plate 8 is in contact with the sedimentation area 5. Then, the driving motor 12 is turned on, and the driving motor 12 drives the cleaning vertical plate 9 and the cleaning inclined plate 8 to rotate through the connecting block 11, so as to clean the precipitated impurities remaining on the inner wall of the impurity discharge pipe 3 and the sedimentation area 5 respectively, so as to avoid the residual impurities from affecting the subsequent static clarification and impurity removal work.
[0026] The connecting block 11 specifically includes an inner ring, an outer ring and a connecting rod. The connecting rod is used to connect the inner ring, the outer ring and the cleaning vertical plate 9 in sequence. The inner ring is fixedly connected to the rotating shaft of the driving motor 12. The outer ring is used to strengthen the connection between the inner ring and the connecting rod. The gap between the inner ring and the outer ring and the gap between the outer ring and the impurity discharge pipe 3 are used to discharge the residual impurities cleaned out.
[0027] The solenoid valve, hydraulic cylinder 13 and drive motor 12 used in the present application are all commonly used electronic components in the prior art. Their specific structures, working principles and circuit connections are all well-known technologies and will not be described in detail here.
[0028] According to a preferred technical solution, scrapers 10 are fixedly provided on both side surfaces of the cleaning inclined plate 8 and the cleaning vertical plate 9. The scrapers 10 are arranged on the outside and are relatively thin, so that the cleaning effect is better.
[0029] A further preferred technical solution is that the number of the cleaning inclined plates 8, cleaning vertical plates 9 and scrapers 10 is not less than five groups, and at least five groups of cleaning inclined plates 8 are evenly arranged on the side around the connecting block 11.
