Technical Field
The utility model relates to the technical field of wastewater treatment devices, in particular to a device for treating wastewater by hydrolyzing methyl phenyl chlorosilane.
Background
Hydrochloric acid waste water is generated after the hydrolysis of the methyl phenyl chlorosilane, and hydrochloric acid is corrosive, so that the hydrochloric acid can be discharged after neutralization. The neutralizing material is typically a calcium hydroxide solution.
Generally, calcium hydroxide solution is prepared by adding water into calcium oxide, and then is conveyed into a hydrochloric acid bucket to be neutralized with hydrochloric acid. Not only does the reaction to form calcium hydroxide require a large amount of water, but also the dilution of the calcium hydroxide solution to a specific concentration requires a large amount of water. This results in waste of water resources.
Therefore, how to overcome the above-mentioned drawbacks is a problem to be solved by the person skilled in the art.
Disclosure of Invention
In order to solve the technical problems in the background technology, the utility model discloses a device for treating waste water generated by hydrolyzing methyl phenyl chlorosilane.
The utility model provides a methyl phenyl chlorosilane hydrolysis wastewater treatment device which comprises an auger, a storage vat, a weighing assembly and a neutralization vat which are sequentially arranged from top to bottom;
the auger conveys the calcium hydroxide powder into the storage bucket;
the neutralization barrel is used for placing hydrochloric acid wastewater;
a stop valve is arranged at the outlet of the storage barrel;
the weighing assembly controls the cut-off valve to open and close, and quantitative calcium hydroxide powder is input into the neutralization barrel.
Firstly, lifting a ton bag provided with calcium hydroxide powder to an inlet of an auger, then cutting the bottom of the ton bag, enabling the calcium hydroxide powder to fall into the auger, and conveying the calcium hydroxide powder into a storage bucket by the auger; according to the content of hydrogen chloride in the hydrochloric acid wastewater in the neutralization barrel, the weight of the calcium hydroxide powder to be used is calculated, then under the combined action of the stop valve and the weighing assembly, the quantitative calcium hydroxide powder falls onto the weighing assembly, and finally the quantitative calcium hydroxide powder is poured into the neutralization barrel. The calcium hydroxide powder is directly subjected to neutralization reaction with hydrochloric acid, so that a large amount of water can be saved, and water resource waste can be avoided. And the stop valve and the weighing assembly also enable the quantity of the calcium hydroxide powder falling into the neutralization barrel to be more accurate.
The weighing assembly has the specific structure that: the weighing assembly comprises a measuring barrel, a supporting plate is arranged in the measuring barrel, and a weighing sensor is arranged at the lower end of the supporting plate.
After weighing, powder in the measuring barrel is poured into the neutralizing barrel generally manually, and the operation is complicated, so that the problem is further improved and solved, and specifically, two opposite sides of the measuring barrel are provided with rotating shafts, wherein one rotating shaft is driven by a first gear motor. Therefore, the first gear motor drives the barrel to turn over, and powder can be poured into the neutralization barrel.
Because the calcium hydroxide powder falls into the storage vat from the auger, there is powder that wafts out, so further improvement solves this problem, and specifically, the entry of storage vat is flaring form, and the export of auger inserts in the entry of storage vat.
When the calcium hydroxide powder falls into the neutralization barrel, the reaction is slower, so that the problem is further improved and solved, and in particular, a stirring shaft is also arranged in the neutralization barrel, and one end of the stirring shaft is driven to rotate by a second speed reducing motor; the stirring shaft is provided with a stirring paddle.
Further, the stirring paddle is spiral. Thus, the liquid in the neutralization barrel directionally flows, the flow speed is faster, and the reaction is more complete.

Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
Embodiment one:
as shown in fig. 1, the utility model relates to a methyl phenyl chlorosilane hydrolysis wastewater treatment device, which comprises an auger 1, a storage vat 2, a weighing assembly 3 and a neutralization vat 4 which are sequentially arranged from top to bottom. The neutralization barrel 4 is made of plastic material.
Auger 1 is used for carrying calcium hydroxide powder, specifically: and lifting the ton bag provided with the calcium hydroxide powder to the position right above the inlet of the auger 1, then cutting the bottom of the ton bag, enabling the calcium hydroxide powder to fall into the auger 1, and conveying the calcium hydroxide powder into the storage vat 2 by the auger 1.
Hydrochloric acid wastewater generated after the hydrolysis of the methyl phenyl chlorosilane in the reaction kettle is conveyed into the neutralization barrel 4.
The outlet of the storage vat 2 is provided with a stop valve 8 which is an electric ball valve.
The weighing component 3 is used for controlling the opening and closing of the stop valve 8 and inputting quantitative calcium hydroxide powder into the neutralization barrel 4. The method comprises the following steps: as shown in fig. 2, the weighing assembly 3 includes a measuring tub 31 having a support plate 32 provided therein, and a load cell 33 provided at a lower end of the support plate 32. And calculating the weight of the calcium hydroxide powder to be used according to the content of the hydrogen chloride in the hydrochloric acid wastewater in the neutralization barrel 4. And then compared with the upper weighing limit of the load cell 33. If the upper limit of the weight of the load cell 33 is greater than the weight of the required calcium hydroxide powder, the load cell is weighed once; otherwise, the weight is averaged multiple times.
When the weighing sensor 33 weighs the set weight, the stop valve 8 is controlled to be closed, and the powder in the measuring barrel 31 is poured into the neutralizing barrel 4; if multiple weighing is required, the powder is poured into the neutralization tank 4 multiple times.
The calcium hydroxide powder is directly reacted with hydrochloric acid to generate neutralization reaction, so that a large amount of water can be saved, and water resource waste can not be caused. But also the shut-off valve 8 and the weighing assembly 3 make the amount of calcium hydroxide powder falling into the neutralization tank 4 more accurate.
