Problems solved by technology

The current domestic liquid sodium silicate compounding device generally adopts a vertical chemical compounding kettle, which has disadvantages such as low production efficiency, low output, difficult operation, high energy consumption, and high maintenance cost, as follows:
[0004] 1. The construction and use costs of vertical chemical tanks are high
The vertical chemical material tank needs to be built with a corresponding height steel structure escalator outside; if the vertical chemical material tank is built outdoors, the heat dissipation of the tank body is fast, which increases the insulation cost and energy consumption of the tank body, and if it is built in an indoor factory building, the height will be increased accordingly. Increased supporting construction costs
[0005] 2. Low production efficiency: the vertical chemical kettle has only one solid sodium silicate feeding port on the upper part, and the height of the feeding port on the top of the kettle is about 5 meters. It is necessary to transport the solid sodium silicate block to the kettle with equipment such as bucket lifts or belts. top, and then added to the vertical chemical tank, greatly increasing the feeding time
The bottom area of ​​the vertical chemical tank is small, only one discharge pipe can be installed, and the discharge speed is slow
[0006] 3. The operator of the vertical chemical kettle is at high risk: after feeding, the operator needs to go up to the top of the 5-meter-high kettle along the spiral staircase outside the vertical chemical kettle, and install it on the small working surface on the top of the vertical chemical kettle. Filling port sealing cap
[0007] 4. High steam consumption: There are few steam pipes inside the vertical chemical tank, and the amount of steam introduced per unit time is small. In order to completely dissolve the solid sodium silicate, multiple steam pressure and pressure relief operations are required, which increases the material time and steam consumption
[0008] 5. High maintenance cost: There is a discharge port under the grate at the bottom of the vertical chemical tank, and the grate can block undissolved solid sodium silicate when discharging
The grate in the vertical chemical tank is easy to collapse, which leads to the blockage of the discharge port, and the serious problem that the liquid product has a layer and cannot be discharged, resulting in a decline in product quality and equipment failure.

Embodiment 1

[0043] Such as figure 1 As shown, this embodiment introduces a chemical material device for the production of liquid sodium silicate, which is used for static chemical material, and includes a cylinder 1 whose axis extends horizontally. That is, the cylinder body 1 is a horizontal cylinder body.

[0044]The chemical material device of the present invention is essentially a horizontal chemical material tank. The horizontal chemical material tank has low cost and takes up little space. The horizontal chemical material tank can be installed in the workshop, and liquid The sodium silicate filter platform makes full use of space advantages; it reduces the cost of installing insulation on the outer wall of the kettle. The horizontal feed tank of the present invention is only about 3 meters away from the ground at the feeding port 4, which reduces the transport distance of the solid sodium silicate block, accelerates the feeding speed, and reduces the feeding time. The grate 7 of t...

Embodiment 2

[0048] Such as Figure 1-3 As shown, the difference between this embodiment and Embodiment 1 is that there is at least one feeding port 4 on the top of the cylinder body 1, and the cylinder body 1 on the side of the feeding port 4 is provided with a water filling port 2, a pressure gauge 15, an emptying port 5, and a safety valve. A valve 19, a manhole 3 and at least one sampling port 6 are provided on the side of the cylinder body 1, and at least one drain port 11 is provided at the bottom of the cylinder body 1. Manhole 3 is arranged higher than grate 7.

[0049] Specifically, the feeding port 4, the water feeding port 2, the pressure gauge 15, the emptying port 5, the safety valve 19, the cleaning port 11 and the manhole 3 are all arranged on the straight cylinder, and the sampling port 6 is arranged on the cover.

[0050] Preferably, a feeding port 4 is respectively provided on both sides of the top of the cylinder body 1 .

[0051] The horizontal chemical feed kettle of...

Embodiment 3

[0056] Such as Figure 1-5 As shown, the difference between this embodiment and Embodiments 1 to 2 is that a horizontally arranged grate 7 and a steam pipe 10 arranged below the grate 7 are arranged inside the cylinder body 1, and the steam pipe 10 is arranged parallel to the grate 7. A plurality of steam outlet holes 20 are distributed on the pipe wall.

[0057] The steam pipeline 10 of the above structure is convenient for laying, which reduces the difficulty of implementation, and the horizontal chemical tank of the present invention can install more steam pipelines 10 inside. It needs 2 pressurization and 1 depressurization to complete the solid sodium silicate material, thus reducing the steam consumption.

[0058] A steam inlet 17 arranged lower than the grate 7 is provided on the side of the cylinder body 1 , and the steam inlet end of the steam pipe 10 protrudes from the steam inlet 17 to the outside of the cylinder body 1 . The steam inlet 17 is located on the cover...

Abstract

The invention relates to a dissolving device for production of liquid sodium silicate. The dissolving device is used for static dissolving and comprises a barrel body, and the axis of the barrel bodyhorizontally extends; the dissolving device is essentially a horizontal-type dissolving kettle, the horizontal-type dissolving kettle is low in cost and small in occupied space, and can be mounted ina workshop, and a liquid sodium silicate filter platform can be built above the dissolving kettle, so that the space advantage is fully utilized; the distance between charging openings of the horizontal-type dissolving kettle and the ground is only about 3 meters, thus the conveying distance of solid sodium silicate blocks is decreased, and the charging time is shortened; a grate of the horizontal-type dissolving kettle is large in area and can bear a large amount of sodium solid silicate, and thus the production efficiency is improved; and according to the horizontal-type reaction kettle, thevolume of the reaction kettle is increased, the single-kettle yield is increased, as for an existing sodium silicate vertical-type static reaction kettle, the maximum volume is 25 m3, the maximum capacity of the single-kettle liquid sodium silicate is 18 tons, as for the horizontal-type reaction kettle, the volume is 56.6 m3, and the yield of the single-kettle liquid sodium silicate is 42 tons.
