Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sodium silicate production equipment, in particular to a water quenching material treatment device for sodium silicate production. Background Art
[0002] Sodium silicate is widely used, almost in every sector of the national economy. Its molecular formula is: Na2O·nSiO2. n is called modulus, which refers to the molar ratio of SiO2 and Na2O. The larger the modulus, the higher the viscosity of water glass and the more difficult it is to dissolve in water. The main use of solid sodium silicate is to make liquid sodium silicate. Liquid sodium silicate is called water glass and solid sodium silicate is called sodium silicate. There are two production processes for sodium silicate, dry process and wet process. Dry process is to produce sodium silicate by mixing soda ash (Na2CO3) and quartz sand (S) with a particle size of 0.180-0.250mm (60-80 mesh) according to the modulus requirements of the required product. iO2) are mixed evenly in proportion and fed into a horseshoe flame kiln to melt at 1450℃-1500℃. The high-temperature molten product flows out of the kiln outlet and directly enters the cooling water. The high-temperature molten liquid is rapidly cooled and exploded, and quenched into particles in water. The color is green or gray. Because sodium silicate is soluble in water and the sodium silicate produced by this method contains water, it has serious agglomeration and is difficult to store for a long time, which will also bring difficulties to the subsequent chemical processing. In addition, the particles formed by natural water quenching and explosion are of different sizes, so further improvements are needed. Utility Model Content

[0011] The utility model will be further described below in conjunction with the accompanying drawings.
[0012] like Figure 1 A water quenching treatment device for sodium silicate production is shown, including an auger 2, one end of which is fixedly connected to a motor 5, which provides power for the auger 2, the outer shell of the auger 2 is a mesh structure, the auger 2 is provided with a feed port 8 above the end where the motor 5 is located, an air drying bin 1 is fixedly connected below the auger 2, a hot air blower 6 is fixedly connected to one side of the air drying bin 1, an air lock 4 is fixedly connected to the bottom of the air drying bin 1, and a second feed pipe 10 is fixedly connected to the lower end of the air lock 4, the other end of the auger 2 is connected to the feed end of the crushing bin 3 through the first feed pipe 9, two crushing rollers 7 are rotatably connected in the crushing bin 3, the discharge end of the crushing bin 3 is connected to the second feed pipe 10 through the third feed pipe 11 and completes the discharge, and the air lock 4 and the crushing rollers 7 are driven by a variable frequency motor.
[0013] It should be noted that the air lock 4 and the hot air blower 6 used in this embodiment are both existing devices, and their specific structures will not be described in detail.
[0014] In order to screen the water-quenched material, the mesh size of the mesh shell of the auger 2 is 15-20 meshes.
[0015] In order to prevent the water-quenched material from entering the hot air blower 6 and causing damage to the hot air blower 6 , a filter screen 12 is provided at the connection between the output end of the hot air blower 6 and the air drying chamber 1 .
[0016] The working process of this embodiment is as follows:
[0017] During operation, the motor 5, the hot air blower 6 and the variable frequency motor are turned on, and the water-quenched sodium silicate is added to the auger 2 through the feed port 8. While conveying the sodium silicate forward, the auger 2 also plays the role of turning and screening. The hot air blower 6 outputs hot air into the air drying bin 1, and finally the hot air is discharged from the mesh shell of the auger 2. The sodium silicate that is constantly turning in the auger 2 can be dried in the middle, and the sodium silicate with smaller particles falls from the shell of the auger 2 into the air drying bin 1, and finally enters the second feed pipe 10 through the air lock 4; the sodium silicate with larger particles is conveyed to the first feed pipe 9 through the auger 2, and then enters the crushing bin 3. After being crushed by the crushing roller 7, it falls into the third feed pipe 11. After the second feed pipe 10 and the third feed pipe 11 are merged, the processed sodium silicate is conveyed to the lower process together, wherein the crushing roller 7 plays the role of crushing and also plays the role of closing the air, so as to ensure that the hot air output by the hot air blower 6 is finally discharged from the mesh shell of the auger 2.
