Specific implementation manner

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0025] As Figures 1-5 shown, the novel sodium silicate filtering and impurity removing device includes a plurality of vertical plates 1 and a separation barrel 2. A liquid inlet pipe 4 is communicated with the separation barrel 2. A separation mechanism for separating sodium silicate and impurities is arranged in the separation barrel 2. The separation mechanism includes three material guiding hoppers 5 fixedly connected to the inner wall of the separation barrel 2. A first filter screen cylinder 3, a second filter screen cylinder 6 and a third filter screen cylinder 7 are respectively arranged in the three material guiding hoppers 5. Slag discharge pipes 8 are communicated with the lower ends of the first filter screen cylinder 3, the second filter screen cylinder 6 and the third filter screen cylinder 7. The filtering precisions of the first filter screen cylinder 3, the second filter screen cylinder 6 and the third filter screen cylinder 7 gradually increase. A first valve 9 is arranged on the slag discharge pipe 8. A liquid discharge pipe 16 is communicated with the lower end of the lower material guiding hopper 5.

[0026] Sealing mechanisms for sealing the slag discharge pipes 8 are arranged in the first filter screen cylinder 3, the second filter screen cylinder 6 and the third filter screen cylinder 7. The sealing mechanism includes a horizontal plate 12 arranged on the inner wall of the third filter screen cylinder 7. An electric push rod 13 is arranged at the lower end of the horizontal plate 12. A sealing block 11 is fixedly connected to the output end of the electric push rod 13.

[0027] In the present utility model, the cross section of the sealing block 11 is frustum-shaped, and materials can be accumulated on the sealing block 11. The sealing block 11 is made of rubber material.

[0028] In the present utility model, a material guiding plate 14 is fixedly connected to the upper end of the horizontal plate 12. The cross section of the material guiding plate 14 is triangular to prevent materials from accumulating on the horizontal plate 12.

[0029] In the present utility model, a corrugated pipe is arranged at the lower end of the horizontal plate 12. The lower end of the corrugated pipe is connected to the upper end of the sealing block 11, which can prevent liquid from splashing onto the electric push rod 13, thereby improving the rationality of the device design.

[0030] In the present utility model, a plurality of vertical plates 1 are fixedly connected to the upper ends together to form an installation bottom plate 20. A liquid pump 18 is arranged on the upper end of the installation bottom plate 20.

[0031] In the present utility model, a protective cover 10 is fixedly connected to the side wall of the material guiding hopper 5 to prevent the first valve 9 from being damaged by splashing liquid, and a sealing cover 23 is provided on the slag discharge pipe 8.

[0032] In the present utility model, two first observation windows 15 are provided on the side wall of the separation barrel 2, and a second observation window 21 is provided on the separation barrel 2 to facilitate observing the filtration and impurity removal of sodium silicate.

A flow meter 22 is provided on the liquid inlet pipe 4, and a second valve 17 is provided on the liquid discharge pipe 16. Both the first valve 9 and the second valve 17 are solenoid valves.

[0034] In the initial state, the liquid inlet pipe 4 is connected to the sodium silicate input pipeline.

[0035] It should be noted that the present utility model is a new type of liquid sodium silicate filtration and impurity removal device. Sodium silicate enters the separation barrel 2 from the liquid inlet pipe 4. The liquid sodium silicate first enters the first filter mesh cylinder 3, and the impurities in the liquid sodium silicate remain in the first filter mesh cylinder 3. The filtered liquid sodium silicate falls into the second filter mesh cylinder 6 on the first material guiding hopper 5. The second filter mesh cylinder 6 finely filters the liquid sodium silicate, and particles with a smaller diameter are intercepted by the second filter mesh cylinder 6. The filtered liquid sodium silicate falls into the third filter mesh cylinder 7 along the second material guiding hopper 5. The third filter mesh cylinder 7 further finely filters the liquid sodium silicate, and smaller impurities are intercepted. Finally, the liquid sodium silicate is discharged from the liquid discharge pipe 16 below the third material guiding hopper 5. During the process, the liquid sodium silicate can be multi-stage filtered in one device, without the need to use multiple devices for filtration and impurity removal, thus greatly reducing the volume and cost of the device;

[0036] The residues remaining in the first filter mesh cylinder 3, the second filter mesh cylinder 6, and the third filter mesh cylinder 7 can be discharged through the inclined surfaces of the first filter mesh cylinder 3, the second filter mesh cylinder 6, the third filter mesh cylinder 7, and the slag discharge pipe 8 by opening the first valve 9, without the need to disassemble the machine for cleaning.

[0037] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
