Description

Technical Field

[0001] This utility model relates to the field of silica sol equipment technology, specifically to an integrated filtration system for silica sol production. Background Technology

[0002] Silica sol is a colloidal solution formed by amorphous silica particles in water or organic solvents. It is usually a colorless, translucent or milky white viscous liquid. It is chemically stable, solidifies into silica gel when heated, and becomes a viscous substance when cooled below zero degrees Celsius. It has a porous structure, strong hygroscopicity, high temperature resistance, and is not easily deformed. It is widely used in precision casting, electronics industry, coating industry, textile industry, petroleum industry, ceramics industry, papermaking industry and other fields, and is an important inorganic polymer material.

[0003] During the production of silica sol, a filtration system consisting of numerous integrated ultrafilters is used for filtration and concentration. However, precisely because of the large number of ultrafilters, the proper functioning of each ultrafilter is crucial to ensure that the final product concentration meets the standards. If any individual ultrafilter malfunctions, the lack of a monitoring mechanism makes it impossible to detect the filtration effect in a timely manner. This not only results in an insufficient final product concentration, affecting product quality, but also necessitates re-filtration. Due to inconsistent concentrations, re-filtration is more complex, leading to significant time wastage, production delays, and other shortcomings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated filtration system for silica sol production, which solves the problem that existing integrated filtration systems for silica sol production have a large number of ultrafilters and lack a monitoring mechanism, resulting in the inability to detect filtration effects in a timely manner and affecting efficient and qualified production.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An integrated filtration system for silica sol production includes a raw material pipe, a filtrate pipe, and a discharge pipe. Multiple sets of first-stage, second-stage, and third-stage ultrafilters are sequentially connected to the raw material pipe via connecting pipes. The discharge pipe is located at the discharge end of the third-stage ultrafilter. The first-stage, second-stage, and third-stage ultrafilters are all connected to the filtrate pipe via connecting pipes. The multiple sets of first-stage, second-stage, and third-stage ultrafilters are equidistantly arranged along the raw material pipe, filtrate pipe, and discharge pipe, respectively.

[0007] The first-stage ultrafilter, second-stage ultrafilter, and third-stage ultrafilter are respectively equipped with a first-stage filtration detection probe, a second-stage filtration detection probe, and a third-stage filtration detection probe, and are also respectively equipped with a first-stage filtration alarm, a second-stage filtration alarm, and a third-stage filtration alarm.

[0008] The first-order filter detection probe, the second-order filter detection probe, and the third-order filter detection probe are respectively connected to the signals of industrial online conductivity meter one, industrial online conductivity meter two, and industrial online conductivity meter three. Industrial online conductivity meter one, industrial online conductivity meter two, and industrial online conductivity meter three are all connected to the signals of the monitoring computer, and the monitoring computer is also connected to the signals of the first-order filter alarm, the second-order filter alarm, and the third-order filter alarm, respectively.

[0009] Preferably, the first-stage ultrafilter, the second-stage ultrafilter, and the third-stage ultrafilter are all ceramic ultrafiltration membrane filters.

[0010] Preferably, the raw material pipe, filtrate pipe and discharge pipe are all horizontally arranged, and the first-stage ultrafilter, second-stage ultrafilter and third-stage ultrafilter are connected by connecting pipes and installed vertically in an S-shaped distribution.

[0011] Preferably, the first-stage filter alarm, the second-stage filter alarm, and the third-stage filter alarm are all audible and visual alarms, and the industrial online conductivity meter I, the industrial online conductivity meter II, and the industrial online conductivity meter III are respectively installed on both sides of each first-stage ultrafilter, each second-stage ultrafilter, and each third-stage ultrafilter.

[0012] Preferably, each of the first-stage, second-stage, and third-stage ultrafilters has a horizontally mounted connecting pipe on its shell, and the end of the connecting pipe is threaded with a nut. The first-stage filtration detection probe, second-stage filtration detection probe, and third-stage filtration detection probe are respectively inserted and sealed onto the corresponding nut.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention involves installing first-stage, second-stage, and third-stage filtration detection probes on each of the first-stage, second-stage, and third-stage ultrafilters, respectively. The conductivity of these probes is monitored in real-time using corresponding industrial online conductivity meters 1, 2, and 3. The results are received by a monitoring computer. When the conductivity is higher or lower than the normal value, it indicates an filtration abnormality in the corresponding ultrafilter, triggering an alarm via the corresponding first-stage, second-stage, or third-stage filtration alarm. This allows for timely suspension of filtration and repair of the abnormal ultrafilter, preventing the continued production of substandard products, effectively improving production efficiency, and significantly reducing production losses. This invention solves the problem in existing integrated filtration systems for silica sol production where the large number of ultrafilters and lack of monitoring mechanisms prevent timely detection of filtration effectiveness, thus impacting efficient and qualified production.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: an integrated filtration system for silica sol production, including a raw material pipe 1, a filtrate pipe 2, and a discharge pipe 3.

All three ultrafilters are ceramic ultrafiltration membrane filters. The raw material pipe 1, filtrate pipe 2, and discharge pipe 3 are horizontally arranged. The first-stage ultrafilters 5, second-stage ultrafilters 6, and third-stage ultrafilters 7 are connected via connecting pipes 4 and vertically installed in an S-shaped distribution.

[0023] Multiple sets of first-stage ultrafilters 5, second-stage ultrafilters 6 and third-stage ultrafilters 7 are equidistantly arranged along the raw material pipe 1, the filtrate pipe 2 and the discharge pipe 3, respectively. First-stage filtration detection probe 8, second-stage filtration detection probe 9 and third-stage filtration detection probe 10 are correspondingly installed on the shells of the first-stage ultrafilters 5, second-stage ultrafilters 6 and third-stage ultrafilters 7, and first-stage filtration alarm 11, second-stage filtration alarm 12 and third-stage filtration alarm 13 are also correspondingly installed on the first-stage ultrafilters 5, second-stage ultrafilters 6 and third-stage ultrafilters 7.

[0024] The first-stage filter alarm 11, the second-stage filter alarm 12, and the third-stage filter alarm 13 are all audible and visual alarms. The industrial online conductivity meter 14, the industrial online conductivity meter 25, and the industrial online conductivity meter 316 are respectively installed on both sides of each first-stage ultrafilter 5, each second-stage ultrafilter 6, and each third-stage ultrafilter 7.

[0025] A connecting pipe 18 is horizontally installed on the shells of the first-stage ultrafilter 5, the second-stage ultrafilter 6 and the third-stage ultrafilter 7 respectively. The end of the connecting pipe 18 is threaded with a nut 19.

This allows for timely suspension of filtration and repair of the abnormal ultrafilter, preventing the continued production of unqualified products, effectively improving production efficiency, and greatly reducing production losses.
