Description

technical field [0001] The invention relates to the technical field of sodium silicate production, in particular to a filtration device for continuous production of sodium silicate. Background technique [0002] At present, the production process of sodium silicate is a batch production process; a production batch of the batch production process needs to discharge the sodium silicate fluid generated by the reaction in the reactor to the filter tank, and then pass through the plate and frame suction filtration device in the filter tank. However, the existing plate and frame suction filtration device is fixed in the filter tank, and the plate and frame suction filtration device is in the negative pressure filtration, and the incompletely reacted quartz sand in the sodium silicate fluid will adhere to the plate and frame suction filtration. The filter screen of the device blocks the filter holes of the filter screen, which reduces the filtration efficiency of the plate-and-fram...

Problems solved by technology

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses a continuous sodium silicate production filtration device, including a filter tank, a centrifugal filter device, a rotary truss combination, a vacuum suction filter pipe, a solid waste pump, and an annular track; the filter tank It is circular, and it is set below the ground, and the side is provided with a filter tank feed port; the bottom of the filter tank is inclined, and an annular pool edge is arranged above the ground, and a ring track is fixedly installed along the top of the pool; the centrifugal filter device A filter screen is fixedly arranged on the upper part, and a central pipe is fixedly arranged in the center; the centrifugal filter device is installed in the filter pool in rotation; The rotation is arranged on the annular track along the top of the filter pond; the vacuum suction filter pipe is fixedly arranged on the upper part of the center pipe; the solid waste pump is fixedly arranged on the side of the filter pond; the sodium silicate continuous production filter device of the present invention is in the When working, the sodium silicate fluid is output from the reaction kettle to the filter pool, the centrifugal filter rotates at a set speed in the filter pool, and the sodium silicate fluid flows through the outer surface of the filter at a certain speed. Under the action, part of the sodium silicate fluid on the outer surface of the filter screen enters the inner side of the filter screen after being filtered, and is transported to the blending pool by the vacuum suction filter; at the same time, the incompletely reacted quartz sand remaining on the outer surface of the filter screen flows in the sodium silicate fluid Under the action, it is washed to the edge of the filter tank, and falls to the bottom of the filter tank after sedimentation; under the action of the inclined surface at the bottom of the filter tank, it finally collects at the lowest point of the filter tank; the incompletely reacted quartz sand collected at the bottom of the filter tank passes through the solid The waste pump is input to the waste solid recovery device; the sodium silicate continuous production filter device of the present invention solves the problem that the plate and frame suction filter device needs to be cleaned regularly, and the filter tank needs to regularly clean the deposited quartz sand, so the sodium silicate filter is realized. Continuity of production while solving the problem of environmental pollution caused by liquid waste
