[0002] The sodium silicate powder produced by the crystallization method needs to be dried, usually using a tunnel dryer. During the drying process, some of the powder will clump together. If the dried material is directly bagged, the quality of the powdered sodium silicate product will be reduced.

[0003] At the same time, because the traditional tunnel dryer basically does not turn over the powdered sodium silicate during the drying process, the sodium silicate powder pressed underneath is not easy to dehydrate, which results in a longer drying time for the sodium silicate powder.

By continuously turning over the sodium silicate powder to be dried, the powder can be fully exposed to a heat source, thereby achieving rapid dehydration of the sodium silicate powder. At the same time, by setting a vibrating screen to crush and sieve the sodium silicate powder during the drying process, the sodium silicate powder can be effectively prevented from clumping together during the drying process, thereby improving the quality of the powdered sodium silicate, and effectively solving the problems in the background technology.

[0013] 1. The drying device can improve the quality of powdered sodium silicate products. By constantly turning over the sodium silicate powder to be dried, the powder can be fully exposed to the heat source, thereby achieving rapid dehydration of the sodium silicate powder.

The electric heating wire 12 is started simultaneously, and the electric heating wire 12 heats the sodium silicate powder so that the sodium silicate powder can be dried quickly.

[0035] Specifically, the electric heating wire 12 heats the thermally conductive silica gel, and the thermally conductive silica gel heats the cylindrical thermally conductive inner shell 91, so that the material can be dried quickly. The presence of the thermally conductive silica gel allows the cylindrical thermally conductive inner shell 91 to be heated evenly.

[0036] More specifically, the electric heating wire 12 and the thermally conductive silica gel are only laid on the lower end of the outer side surface of the cylindrical thermally conductive inner shell 91 .

[0037] Furthermore, the vibrating filter screen 14 includes an outer cover 141, which is composed of a cylindrical section and a conical section. The outer cover 141 is connected to a bearing mounting seat 145 through a support rod 144 arranged at the left end of its inner side surface. The bearing mounting seat 145 and the conical section of the outer cover 141 are both rotatably connected to the main shaft 16 through bearings.

[0039] Furthermore, the oscillator 11 includes a mounting frame 111 arranged on the inner side of the conical gradient cylinder 15 and a strong magnet 113 installed on the baffle 146. An electromagnet 114 is provided on the inner side of the mounting frame 111 at one end close to the strong magnet 113, and the outer side of the baffle 146 is connected to the mounting frame 111 through a spring 112 at one end away from the strong magnet 113.

[0040] Specifically, the electromagnet 114 regularly repels the strong magnet 113, so that the strong magnet 113 can drive the outer cover 141 to repeatedly swing back and forth around the main shaft 16 through the baffle 146, and the spring 112 is repeatedly stretched and compressed, which can achieve a good vibration enhancement effect.

[0041] During use: the sodium silicate powder filtered out after crystallization is conveyed to the interior of the wet material box 2 through a screw conveyor, and the wet material enters the interior of the stepped barrel 9 through the discharge port at the bottom of the wet material box 2, and the reduction motor 1 is started. The reduction motor 1 drives the spiral conveying blade to rotate through the main shaft 16, and the spiral conveying blade pushes the wet material along the inner wall of the stepped barrel 9 toward the collecting box 7. At this time, the electric heating wire 12 is energized to heat the wet material. Synchronously, the external vacuum fan is started, and the air heated by the electric heater 13 enters the interior of the stepped barrel 9. While the dry hot air heats the wet material, the water vapor inside the stepped barrel 9 is taken out.

[0042] The powder enters the vibrating filter screen 14 through the end of the fine section cylinder, and the oscillator 11 is started. The oscillator 11 drives the vibrating filter screen 14 to repeatedly rotate forward and reverse at a small angle around the main shaft 16, thereby achieving material crushing and screening. The screened material enters the coarse section cylinder for further drying, and the dried material enters the collection box 7.

[0043] It is worth noting that the input ends of the electromagnet 114, the electric heater 13 and the reduction motor 1 are all electrically connected to the output end of the external power supply through an external control switch.
