Abstract
The utility model relates to a grinder bearing dustproof device. The grinder bearing dustproof device comprises a grinder material-grinding bin, a grinder feeding pipeline and a grinder spindle cavity, wherein a supporting bearing which is used for supporting a spindle is arranged in the grinder spindle cavity; a sealing component is arranged between the grinder spindle cavity and the grinder material-grinding bin; and the grinder spindle cavity is full of lubricating oil. The grinder bearing dustproof device is characterized by also comprising a pressure balance device which is used for balancing pressure between the grinder spindle cavity and the grinder material-grinding bin. Compared with the existing grinder, the grinder bearing dustproof device has the advantages that the pressure balance device is additionally arranged and is used for inputting the pressure, so that the pressure between the grinder material-grinding bin and the grinder spindle cavity tends to be balanced or tends to be slightly greater than the internal pressure of the grinder material-grinding bin, dust cannot enter the grinder spindle cavity, the purity of the lubricating oil in the grinder spindle cavity is improved, and the replacement time of the lubricating oil is prolonged. The grinder bearing dustproof device also has an auxiliary oil leakage function; residue in the grinder spindle cavity can be blown away; the operational environment of the supporting bearing is further improved.
Description
Technical field
The utility model belongs to pulverizer manufacturing technology field, particularly relates to a kind of pulverizer bearing dust guard.
Background technology
Pulverizer originally is widely used in industrial production, its structure is comparative maturity substantially also, a kind of FFc-37 pulverizer that for example is used for feed processing, pulverizing the storehouse in the feed crushing process pulverizes material, the pulverizer fluted disc rotates at a high speed in crushing process as everyone knows, thereby cause pulverizer to pulverize end pressure rising in the storehouse, because material is low weight, the powder of pulverizing passes the black box of pulverizing between storehouse and the main shaft chamber easily and enters in the main shaft chamber under the situation of high pressure, enter the wearing and tearing that just are easy to cause bearing behind the main shaft chamber, and lubricating oil need often be changed the normal operation of the equipment that could guarantee.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to install, improve bearing service life and equipment work running efficiency, save and safeguard and the pulverizer bearing dust guard of use cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of pulverizer bearing dust guard, comprise pulverizer filler bin, pulverizer feed pipe, the pulverizer main shaft chamber, the spring bearing of supports main shaft wherein is installed in the main shaft chamber, be provided with black box between main shaft chamber and the pulverizer filler bin, described main shaft is full of lubricating oil in the chamber, it is characterized in that: described this dust guard also includes the pressure equaliser of pressure between balance pulverizer main shaft chamber and the pulverizer filler bin.
The utility model can also adopt following technical measures:
Described pressure equaliser mainly comprises the suction nozzle that is installed on the pulverizer main shaft chamber, and described suction nozzle is communicated with the pulverizer main shaft chamber, and described suction nozzle connects source of the gas by air inlet pipe.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, namely set up a cover pressure equaliser in original main shaft chamber, by the pressure equaliser input pressure, the pressure that makes pulverizer pulverize between storehouse and the pulverizer main shaft chamber tends to balance, perhaps be slightly larger than the pressure in the pulverizer pulverizing storehouse, dust just can not fled in the pulverizer main shaft chamber like this, thereby improved the purity of lubricating oil in the pulverizer main shaft chamber, prolonged the replacing time of lubricating oil.In addition, when needs carry out more oil change, lubricating oil in the existing pulverizer main shaft chamber is put unclean, always have residual, above-mentioned pressure equaliser can also be assisted draining, and lubricating oil in the pulverizer main shaft chamber can be gushed fully, but also can blow away the residue that remains in the main shaft chamber, thereby further improve the running environment of spring bearing, improve its service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, pulverizer filler bin; 2, pulverizer feed pipe; 3, pulverizer main shaft chamber; 4, pressure equaliser; 4-1, suction nozzle; 4-2, air inlet pipe.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of pulverizer bearing dust guard, comprise pulverizer filler bin 1, pulverizer feed pipe 2, pulverizer main shaft chamber 3, the spring bearing of supports main shaft wherein is installed in the pulverizer main shaft chamber 3, be provided with black box between main shaft chamber and the pulverizer filler bin, described main shaft is full of lubricating oil in the chamber, and described this dust guard also includes the pressure equaliser 4 of pressure between balance pulverizer main shaft chamber 3 and the pulverizer filler bin.
In the said structure, described pressure equaliser 4 mainly comprises the suction nozzle 4-1 that is installed on the pulverizer main shaft chamber, described suction nozzle is communicated with pulverizer main shaft chamber 3, described suction nozzle connects source of the gas by air inlet pipe 4-2, source of the gas can regularly be controlled unlatching by relay, also can control it by pressure sensor and open and close automatically.
The utility model is compared with existing pulverizer and is set up a cover pressure equaliser, by the pressure equaliser input pressure, the pressure that makes pulverizer pulverize between storehouse and the pulverizer main shaft chamber tends to balance, perhaps be slightly larger than the pressure in the pulverizer pulverizing storehouse, dust just can not fled in the pulverizer main shaft chamber like this, thereby improved the purity of lubricating oil in the pulverizer main shaft chamber, prolonged the replacing time of lubricating oil.
The utility model also has the function of auxiliary draining, namely when needs carry out more oil change, lubricating oil in the existing pulverizer main shaft chamber is put unclean, always have residual, above-mentioned pressure equaliser can also be assisted draining, and lubricating oil in the pulverizer main shaft chamber can be gushed fully, but also can blow away the residue that remains in the main shaft chamber, thereby further improve the running environment of spring bearing, improve its service life.
The above only is to preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any simple modification that every foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all belong in the scope of technical solutions of the utility model.
