The utility model has the characteristics of simple structure, preparation and maintenance cost are low, use reliable safety, reach the concentrated sulfuric acid of prevention and spatter outward and cause the personal injury occurence of failure and can collect the purpose that the waste liquid has avoided environmental pollution.
Description
Technical Field
The utility model relates to an inorganic chemical material white carbon black apparatus for producing, concretely relates to sulphuric acid pipeline flange leaks safety protection and shelters from ring device.
Background
Concentrated sulfuric acid is one of main raw materials for producing precipitated white carbon black, and is pumped to a 20-meter overhead tank by a pump through a pipeline for reaction in the actual production process. The pipelines for conveying the sulfuric acid are generally connected by flanges and acid-resistant gaskets are used; because the pressure is higher, the condition of leakage and splashing can occur at the flange part due to corrosion or gasket aging in practical use, and the sulfuric acid has extremely high corrosivity, can cause damages such as burning, even carbonization and the like of a human body, and causes pollution to the surrounding environment. Therefore, in the prior art, the steel plate hoops are commonly used and fastened by bolts, and the problems that after the time is long, the corrosion is serious, the overhaul is inconvenient, the bolts need to be cut off, the problems cannot be fundamentally solved, and materials and manpower are wasted are solved.
Disclosure of Invention
The utility model aims at providing a simple structure, preparation and maintenance cost are low, use reliable sulphuric acid pipeline flange to reveal safety protection and shelter from ring device, solve among the sulphuric acid pipeline of one of the main raw materials of sediment white carbon black production flange junction and leak the problem that the splash caused personal safety and polluted environment.
In order to realize the purpose, the safety protection blocking ring device for the flange leakage of the sulfuric acid pipeline comprises an annular blocking ring and an iron wire; the annular shielding ring is a section of plastic pipe, the inner diameter of the annular shielding ring is matched with the outer diameter of the flange, the length of the annular shielding ring is larger than the thickness of two connecting flanges, an opening seam is arranged along the longitudinal direction of the annular shielding ring to form an annular shielding ring which can be manually opened and closed, the annular shielding ring is sleeved in the pipeline and moved to the flange when being installed, the opening seam faces downwards, and the annular shielding ring is tightly hooped on the flange by utilizing the original shape restoring elasticity; the iron wire is used for bundling and fixing the annular shielding ring.
The width of the longitudinal opening seam of the annular shielding ring is 8-12 mm.
The sulfuric acid pipeline flange of above-mentioned structure leaks safety protection and shields ring device, shields ring device through installing safety protection additional, has simple structure, and preparation and maintenance cost are low, use reliable safe characteristics, reach the concentrated sulfuric acid of prevention and spatter outward and cause the personal injury occurence of failure and can collect the waste liquid and avoid environmental pollution's purpose.

Fig. 2 is a left sectional structural diagram of the safety protection blocking ring device for flange leakage of sulfuric acid pipeline of the utility model.
Reference numerals: pipeline 1, flange shield ring 2, iron wire 3, flange 4.
Detailed Description
The following description will be made in detail with reference to the specific embodiments of the shielding ring device for flange leakage safety protection of sulfuric acid pipeline of the present invention.
As shown in fig. 1 and 2, the safety protection shielding ring device for flange leakage of sulfuric acid pipeline of the present invention comprises an annular shielding ring 2 and an iron wire 3; the annular shielding ring 2 is a section of PVC water supply pipe, the inner diameter of the annular shielding ring is matched with the outer diameter of the flange 4, the length of the annular shielding ring is larger than the thickness of two connecting flanges, an opening seam with the seam width of 10mm is arranged along the longitudinal direction of the annular shielding ring to form an annular shielding ring which can be manually opened and closed, the annular shielding ring is sleeved on the flange 4 from the pipeline 1 and moves to the position with the opening seam facing downwards during installation, and the annular shielding ring is tightly hooped on the flange 4 by utilizing the original shape restoring elasticity; the iron wire 3 is used for bundling and fixing the annular shielding ring 2.
When the device works, sulfuric acid flows in the pipeline 1 and has certain pressure, when the device passes through the connecting flange 4, the phenomenon of sulfuric acid leakage can occur due to the possibility of aging, corrosion of a flange body and corrosion of a bolt of a gasket, the flange shielding ring 2 is manually broken from an opening seam of the annular shielding ring and sleeved into the pipeline and then moved to the flange, the flange is tightly clamped on the flange by using the original shape restoring elasticity, and then the flange is bundled and fixed by using the iron wire 3; if sulfuric acid leaks, it will splash onto the flange shield ring 2 and drip down along the ring wall from the bottom opening seam, and be collected by the container. Because the flange shielding ring 2 is bundled and fixed by the iron wire 3, the flange shielding ring 2 can be moved to the pipeline 1 only by cutting off the iron wire 3 during maintenance, the manufacturing and maintenance cost is low, the material is easy to obtain and is not easy to corrode, and the manufacturing, installation, operation, use and maintenance are convenient.
