Description
Technical field
The utility model relates to technical field of mechanical, is specifically related to a kind of mechanical seal for the production of food machinery.
Background technique
Mechanical seal is that a kind of main elasticity that relies on carries out pretension to sealing pair, makes sealing pair compress and reach the axial end seal arrangement of sealing under medium and the acting in conjunction of elastic element pressure.And for the black box for the production of food machinery, the axial drive fit of black box has axle, the retainer in black box and there is between axle certain gap; Because Environmental Conditions is special, have some gaps to be just easy to cause food residue a little and result in blockage, the phenomenon such as mouldy, rotten, one comes some gaps that these residual food plug mechanical seal device, causes Sealing space to be extruded, affects sealing effect; Two take these food due to mouldy, rotten, have a strong impact on the quality of production of subsequent batches food.
In addition, above-mentioned traditional black box, particularly motive sealing, the rubber seal wherein used easily is subjected to displacement under the action of the spring, will cause sealing effect degradation once be subjected to displacement.
Model utility content
The utility model, for the above-mentioned deficiency of prior art, provides one to prevent food from entering black box gap, effectively ensures the using effect of black box, and also can prevent the mechanical seal for the production of food machinery that mouldy, rotten food is detained.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of mechanical seal for the production of food machinery, comprise the friction tight retainer with axle, one end of retainer is provided with rotating ring, be provided with O shape between described retainer and rotating ring to enclose, coordinated by driving pin transmission between retainer with rotating ring; It is characterized in that: described retainer is provided with L pad away from one end of rotating ring, and L pad and drive fit between retainer and axle.
Adopt said structure, owing to being provided with L pad at retainer away from one end of rotating ring and L pad and retainer and axle drive fit; Thus filled up the gap between retainer and axle, effectively prevent the blocking of food, delay, go bad, thus the quality of the stable and food of available protecting sealing effect.
As preferably, described retainer is provided with radial cavity on the madial wall of L pad one end, and described L pad corresponding position is provided with the projection fitted with cavity; Adopt this structure, can effectively ensure between L pad and black box in conjunction with fastness, effectively prevent L pad from axially coming off or slide, displacement.
As preferably, described rotating ring is provided with V-shaped groove on the outer side wall of L pad one end; Adopt this structure, before the pump housing is not installed, the V-shaped groove herein rotating ring arranged can contact with O shape circle, because O shape circle is for elastic material is as material preparations such as rubber, realize and fully the contacting of V-shaped groove under the extruding of outside retainer, thus increase the surface friction drag of rotating ring axis, sliding axially of effective anti-stop ring; After installing pump, rotating ring is promoted inside, and V-shaped groove and seal ring depart from, and realizes running well.
Accompanying drawing explanation
Fig. 1 the utility model is for the production of the axial sectional view structural representation of mechanical seal of food machinery.
Fig. 2 the utility model is for the production of the mechanical seal A portion partial enlarged drawing of food machinery.
Fig. 3 the utility model is for the production of the mechanical seal B portion partial enlarged drawing of food machinery.
The axial sectional view structural representation of Fig. 4 the utility model L pad.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail, but is not limited only to following examples.
As shown in Figure 1-2: a kind of mechanical seal for the production of food machinery of the present utility model, comprise the friction tight retainer 1 with axle, one end of retainer 1 is provided with rotating ring 2, is provided with O shape and encloses 3 between described retainer 1 and rotating ring 2, is coordinated between retainer with rotating ring by driving pin 4 transmission; It is characterized in that: described retainer is provided with L pad 5 away from one end of rotating ring, and L pad and drive fit between retainer and axle.
Adopt said structure, owing to being provided with L pad at retainer away from one end of rotating ring and L pad and retainer and axle drive fit; Thus filled up the gap between retainer and axle, effectively prevent the blocking of food, delay, go bad, thus the quality of the stable and food of available protecting sealing effect.
Retainer 1 described in this practicality is provided with radial cavity 1.1 on the madial wall of L pad one end, and described L pad corresponding position is provided with the projection 5.1 fitted with cavity; Adopt this structure, can effectively ensure between L pad and black box in conjunction with fastness, effectively prevent L pad from axially coming off or slide, displacement.
Rotating ring 2 described in this practicality is provided with V-shaped groove 2.1 on the outer side wall of L pad one end; Adopt this structure, before the pump housing is not installed, the V-shaped groove herein rotating ring arranged can contact with O shape circle, because O shape circle is for elastic material is as material preparations such as rubber, realize and fully the contacting of V-shaped groove under the extruding of outside retainer, thus increase the surface friction drag of rotating ring axis, sliding axially of effective anti-stop ring; After installing pump, rotating ring is promoted inside, and V-shaped groove and seal ring depart from, and realizes running well.
L pad of the present utility model, because one-sided axial sectional view is L-shaped, turn round and look at and be defined as L pad, its material can be the flexible materials such as rubber, or other has the material of deformation nature.
