Abstract
The utility model discloses a mechanical sealing device of an absorption tower blender and belongs to the field of machinery. The mechanical sealing device of the absorption tower blender aims to guide a line of purified water into a mechanical sealed chamber, and enables the absorption tower blender machinery to work in the environment that the machinery is sealed well. A blender mechanical sealed movable ring is sleeved on an absorption tower blender shaft in the water-purifying cavity of the absorption tower. A blender mechanical seal clean ring is inserted into the outer edge of the water-purifying cavity of the absorption tower, and a water-washing hole communicated with the water-purifying cavity is arranged on the blender mechanical seal clean ring. A seal board is arranged on the inner edge of the water-purifying cavity, and the seal board is sleeved on the absorption tower blender shaft. The mechanical sealing device of the absorption tower blender is simple in structure and convenient to use, and reduces abrasions and corrosions of the mechanical sealed movable ring and the mechanical stationery ring, keeps the durable performance of a circular spring, and prolongs the mechanical sealing service life of absorption tower blender equipment.
Description
Technical field
The utility model belongs to mechanical field, and what relate to is the seal arrangement of absorption tower stirrer.
Background technique
Existing absorption tower stirrer mechanical seal device moves in acid slurries, seals by two Sealings that cooperatively interact.The shortcoming of this device is: 1, work in the existing acid slurries of Sealing about PH=5.6, make the Sealing corrosion.2, Sealing is worked in the slurries of absorption tower, and owing to relative sliding between two Sealings, Sealing weares and teares.3, stirrer is in operation always axial float, this just require a Sealing under the effect of spring along with another Sealing moves, reach sealing effect to guarantee that two Sealings are close to, in a short time fouling, corrosion can occur at acid slurries medi-spring, and elasticity weakens mechanical seal is sewed.
Summary of the invention
The purpose of this utility model is that one tunnel source of purified water is caused in the mechanical seal chamber, the absorption tower stirrer mechanical seal device that mechanical seal is worked under good environment.
The absorption tower stirrer shaft cover of the utility model in the water-purifying cavity on absorption tower has the stirrer mechanical sealing linkage ring; The water-purifying cavity outer on absorption tower is inserted stirrer mechanical seal and is only encircled, and at the clean ring of stirrer mechanical seal the flushing water hole that communicates with water-purifying cavity is arranged; The edge is equipped with sealing plate in the water-purifying cavity on absorption tower, and sealing plate is enclosed within on the stirrer shaft of absorption tower.
The utility model sealing plate material adopts teflon.
The utility model sealing plate is 0.2mm with the gap of absorption tower stirrer shaft.
The utility model is made a sealing water in the work chamber of mechanical seal, draw so far chamber of a pure water route, and mixing plant mechanical seal is being worked in the environment preferably.And install sealing plate (polyfluortetraethylene plate) additional at the absorption tower wall, and keeping the 0.20mm gap with stirrer shaft, hydraulic pressure is little greater than the tower internal pressure.The utility model is simple in structure, and is easy to use.Reduce the wearing and tearing of mechanical seal dynamic and static ring, corrosion, kept the permanent performance of rotating ring spring, prolonged the working life of absorption tower mixing plant mechanical seal.

Embodiment
Absorption tower stirrer shaft 1 cover of the utility model in the water-purifying cavity 7 on absorption tower 4 has stirrer mechanical sealing linkage ring 5; The clean ring 2 of stirrer mechanical seal is inserted in water-purifying cavity 7 outers on absorption tower 4, at the clean ring 2 of stirrer mechanical seal the flushing water hole 3 that communicates with water-purifying cavity 7 is arranged; The water-purifying cavity 7 interior edges on absorption tower 4 are equipped with sealing plate 6, and sealing plate 6 is enclosed within on the absorption tower stirrer shaft 1.
The utility model sealing plate 6 materials adopt teflon.
The utility model sealing plate 6 is 0.2mm with the gap of absorption tower stirrer shaft 1.Guarantee that in the mechanical seal bin be pure process water.
Process water is introduced in the flushing water hole, and the little absorption tower internal pressure that is higher than of hydraulic pressure is worked mechanical seal in good environment.
