Abstract
The invention relates to a spindle sealing and sand preventing isolation device for a mixer of a pre-impregnation tower. The spindle sealing and sand preventing isolation device comprises an isolating sand prevention cone (2), a sealing stationary ring (3) and a sealing rotating ring (4), wherein the isolating sand prevention cone (2) is fixed on a bearing chamber (5); the sealing stationary ring (3) is fixed on the isolating sand prevention cone (2); the sealing rotating ring (4) is fixed on a bottom auxiliary mixing blade (6) and rotates along with rotation of the mixing blade; a gap of only 1 mm is formed between the sealing rotating ring and the sealing stationary ring. Under the sealing action of both the stationary ring and the rotating ring, a packing seal (8) of a spindle (7) is isolated from sand, and sand can not enter the sand preventing isolation device, so that damage to sealing, caused by the reason that deposited sand grains enter the packing seal (8), is avoided, and liquid leakage and equipment failures are prevented.
Description
Technical field
The present invention relates to pulping and paper-making preimpregnation tower, be specifically related to a kind of main shaft seal sand control isolation mounting of preimpregnation tower stirrer.
Background technique
The preimpregnation tower is the important digesting apparatus during continuous steaming-boiling technology is produced in the pulping and paper-making production line.Under the wood chip that enters the preimpregnation tower effect of section's High Temperature High Pressure within it, react with cooking liquor, realize predecomposition.
The preimpregnation tower comprises housing, top spiral, top sieve basket, bottom material scraper and hydraulic driving system.The effect of bottom material scraper is that the wood chip that will finish pre-boiling stirs and scrapes, and is delivered to next workshop section.In the prior art, the seal arrangement of material scraper main shaft is packing_seal, shown in accompanying drawing 1, accompanying drawing 2.
Owing to entering impurity such as containing sand grains in the wood chip of preimpregnation tower, the density of sand grains easily is deposited on greatly the bottom of tower, and the height of discharge gate will be higher than the seal arrangement of main shaft, therefore, is deposited at the bottom of the tower around the seal arrangement always and can't discharges with regard to having sand grains.Along with the rotation of main shaft, sand grains is easy to enter the packing_seal device, and main shaft and packing_seal are damaged, and causes revealing.
Summary of the invention
In order to overcome defects, the object of the invention is to, a kind of main shaft seal sand control isolation mounting of preimpregnation tower stirrer is provided, sand is isolated in the packing_seal outside, prevent that sand from entering main shaft and packing_seal, cause to avoid sealing wear revealing.
The present invention is that the technological scheme that its technical problem of solution adopts is:
The main shaft seal sand control isolation mounting of preimpregnation tower stirrer is characterized in that: comprise the anti-abrasive cone, close of isolation
Envelope fixed ring and moving sealing ring three parts; The anti-abrasive cone of isolation is fixed on the bearing chamber, and the sealing fixed ring is fixed on isolation
On the anti-abrasive cone, moving sealing ring is fixed on the secondary mixing blade of bottom, rotates along with the rotation of mixing blade.
Gap between described moving sealing ring and the stationary seal ring only is 1mm; Under the seal action of dynamic and static ring,
Packing_seal and the sand of main shaft are kept apart, and sand can not enter in the sand control isolation mounting, thereby has avoided the sand grains of deposition to enter packing_seal and cause wearing and tearing.
Its beneficial effect provided by the invention is, will cause the impurities such as sand of main shaft and packing seal wearing and tearing externally, and it can not be entered in the sealing, thereby has avoided the sand grains deposition to the gland sealed infringement, has avoided leakage and equipment failure.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is bottom material scraper embryonal structure schematic diagram;
Fig. 2 is sealed structural representation of the present invention;
Fig. 3 is sealing configuration enlarged view of the present invention.
Among the figure: 1. bottom material scraper, the 2. anti-abrasive cone of isolation, 3. stationary seal ring, 4. moving sealing ring, 5. bearing chamber, 6. secondary mixing blade, 7. main shaft, 8. packing_seal.
Embodiment
The anti-abrasive cone 2 of isolation is fixed in bearing chamber 5 upper surfaces, and stationary seal ring 3 is bolted on the anti-abrasive cone 2 of isolation, and moving sealing ring 4 is bolted on the secondary mixing blade 6 of bottom, rotates along with the rotation of secondary mixing blade 6.Gap between moving sealing ring 4 and the stationary seal ring 3 only is 1mm.Under the seal action of dynamic and static ring, the packing_seal 8 of main shaft 7 is kept apart with sand, sand can not enter in the sand cap, and liquid then can enter in the sand control isolation mounting by the gap between moving sealing ring 4 and the stationary seal ring 3, and packing_seal 8 is lubricated.
Claims (2)
1. the main shaft seal sand control isolation mounting of preimpregnation tower stirrer comprises the anti-abrasive cone (2) of isolation, sealing fixed ring (3) and moving sealing ring (4); It is characterized in that: the anti-abrasive cone (2) of isolation is fixed on the bearing chamber (5), sealing fixed ring (3) is fixed on the anti-abrasive cone (2) of isolation, moving sealing ring (4) is fixed on the secondary mixing blade (6) of bottom, rotates along with the rotation of mixing blade.
2. the main shaft seal sand control isolation mounting of preimpregnation tower stirrer according to claim 1, it is characterized in that: the gap between moving sealing ring (4) and the stationary seal ring is 1mm; Under the seal action of dynamic and static ring, packing_seal (8) and the sand of main shaft (7) to be kept apart, sand can not enter in the sand control isolation mounting.
