Description
Technical Field
The utility model relates to an inorganic chemical material white carbon black apparatus for producing, concretely relates to sodium silicate joins in marriage alkali tank bottom thick liquid recovery unit.
Background
The main raw materials for producing the white carbon black by the precipitation method are liquid water glass and sulfuric acid. The liquid water glass is prepared into qualified liquid water glass by dissolving solid water glass through steam pressurization and then putting clarified clear liquid obtained after multiple times of precipitation into an alkali preparation tank. At present, in the prior art, bottom slurry and sediment need to be discharged at regular time and washed, and the discharged substances enter a sewage neutralization tank, so that the slurry and slag sludge contain water glass, the raw materials are wasted, and the environmental protection pressure is increased.
Disclosure of Invention
The utility model aims at providing a simple structure, preparation and maintenance cost are low, convenient to use efficient sodium silicate joins in marriage alkali tank bottom thick liquid recovery unit to solve because of joining in marriage alkali tank bottom thick liquid can not recycle and cause raw and other materials liquid sodium silicate's waste, increased the problem of environmental protection processing pressure.
In order to achieve the purpose, the bottom slurry recovery device of the water glass alkali distribution tank comprises a slag washing tank, a filter press with a clear water pipe, a dilute water glass tank, a discharge pump and a pipeline, wherein the upper part of the slag washing tank is provided with a feed liquid inlet, a feed liquid outlet and a stirring device, and the feed liquid inlet at the upper part of the slag washing tank is connected with the bottom of the alkali distribution tank through the pipeline with a valve; the inlet end of the discharge pump enters from a feed liquid outlet at the upper part of the slag washing tank through a pipeline with a valve and is communicated to the near bottom of the slag washing tank, and the outlet end of the discharge pump is connected with an inlet of a filter press; the outlet end of the filter press is connected with the upper inlet of the dilute sodium silicate tank through a filtrate outlet pipe; and a dilute sodium silicate liquid outlet pipe is arranged at the lower part of the dilute sodium silicate groove.
The water glass alkali distribution tank bottom slurry recovery device with the structure adopts dry-wet separation of the filter press through the newly-added slag washing tank, the filter press and the dilute water glass tank device, has the advantages of simple structure, low manufacturing and maintenance cost and convenient and efficient use, can avoid waste of raw material liquid water glass, reduces the pressure of environmental protection treatment, thoroughly solves the problem that alkali distribution tank bottom slurry cannot be recovered, and achieves the purpose of reducing the production cost.

Reference numerals: the device comprises an alkali preparation tank 1, a slag washing tank 2, a stirring device 3, a discharge pump 4, a clear water pipe 5, a box filter press 6, a filtrate outlet pipe 7, a dilute sodium silicate tank 8 and a dilute sodium silicate liquid outlet pipe 9.
Detailed Description
The bottom slurry recycling device of the water glass alkali distribution tank of the present invention will be further described in detail with reference to the following embodiments.
As shown in fig. 1, the bottom slurry recycling device of the sodium silicate distributing tank of the present invention comprises a slag washing tank 2, a filter press 6 with a clean water pipe 5, a dilute sodium silicate tank 8, a discharge pump 5 and a pipeline, wherein the upper part of the slag washing tank 2 is provided with a feed liquid inlet, a feed liquid outlet and a stirring device 3, and the feed liquid inlet at the upper part of the slag washing tank 2 is connected with the bottom of the sodium silicate distributing tank 1 through the pipeline with a valve; the inlet end of the discharge pump 5 enters from a feed liquid outlet at the upper part of the slag washing groove 2 through a pipeline with a valve and is communicated to the near bottom of the slag washing groove 2, and the outlet end is connected with an inlet of a filter press 6; the outlet end of the filter press 6 is connected with the upper inlet of the dilute sodium silicate tank 8 through a filtrate outlet pipe 7, clarified filtrate enters the dilute sodium silicate tank 8 through an alkali pipe, and the slag washing time of the filter press 6 is controlled by measuring the pH value of the filtrate, so that no or little sodium silicate is contained in filter residues; and a dilute sodium silicate liquid outlet pipe 9 is arranged at the lower part of the dilute sodium silicate groove 8.
When the device works, after the upper clear liquid of the alkali distribution tank 1 is completely pumped out, the remaining slurry containing water glass and partial impurities is discharged from the bottom of the alkali distribution tank 1 and enters the slag washing tank 2 through a pipeline, and a small amount of clear water is used for washing after the discharge is completed to ensure that the bottom of the alkali distribution tank 1 is clean and has no precipitate; the slurry entering the slag washing tank 2 is homogenized under the stirring action of a stirring device 3 on the tank, impurities are prevented from being precipitated, the homogenized slurry is pumped into a box type filter press 6 through a discharge pump 4 for filter pressing, filtrate and filter residues are separated, after the pressure is reached, the discharge pump is stopped, clean water is started to wash the filter residues through a clean water pipe 5, the filtered and clarified filtrate enters a dilute sodium silicate tank 8 through a filtrate outlet pipe 7 for storage, the washing is stopped when a specified pH value is reached, the dilute sodium silicate solution is sucked out through a dilute sodium silicate solution outlet pipe 9 for preparing the solution when the solution is required to be used, and the filter residues are transported outside by a forklift regularly.
