The utility model replacing mechanical sealing and flexible sealing has the advantages of simple mechanism, non-contact and wear-free elements, low costs, long service life and no need to change any element, thereby achieving maintenance-free effect except the maintenance of bearings. In addition, all structures of the apparatuses are non-contact type and all elements are free of wear, thereby being safe and reliable.
Description
Technical field
The utility model belongs to emulsifier and pump is used the device field, relates in particular to the no sealing device of a kind of emulsifier and pump.
Background technology
At present, existing emulsifier, pump and Mixing Machine all have mechanical seal or flexible seal device, this device is used for preventing that latex, liquid and gas from leaking from axle joint seal crack, wherein, the dynamic and static ring of mechanical seal is to finish the sealing task by the contact plane of rotation at a high speed, and flexible sealing is to finish sealing by static sealing ring with tight contact of rotating shaft.Because the friction of motion of contact-making surface all easily produces wearing and tearing, heating, leaks, the life-span is limited, all need fully cooling and periodic replacement, particularly for inflammable, explosive chemicals, such as emulsion, these intrinsic defectives are very serious to the potential safety hazard that production brings.Simultaneously, constantly change sealing and also bring obstruction, increase production cost to production.
The utility model content
The purpose of this utility model is to provide a kind of emulsifier and pump with no sealing device, be intended to solve complex structure in machinery and the flexible seal device, component wear seriously, poor stability, problem that cost is high.
The technical scheme that the utility model is adopted for achieving the above object is: provide a kind of emulsifier and pump no sealing device, comprise that cavity and at least one are arranged at the rotor in the described cavity, described cavity is provided with charging aperture and discharging opening, also comprises a back impeller that can rotate with rotor.
Compared with prior art, the beneficial effects of the utility model are: the utility model has replaced mechanical seal and flexible sealing, and mechanism is simple, all parts are noncontact, no wearing terrain, and cost is low, the long-term use need not be changed any part, reaches the freedom from repairs equipment effect except that bearing.Because the structure of this device all is a non-contact type, and is without any wearing terrain, safe and reliable.

Fig. 2 is the structure cutaway view of the embodiment two that provides of the utility model;
Fig. 3 is the structure cutaway view of the embodiment three that provides of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment one:
As shown in Figure 1, the utility model embodiment one comprises a cylindrical cavity 4 and is horizontally placed in the described cavity 4 and is loaded on rotor 1 on the axle 5, charging aperture 8 and discharging opening 6 are arranged on the described cavity 4, in described rotor 1 side, also being provided with can be with the back impeller 2 of described rotor 1 rotation, described back impeller 2 blades can adopt centrifugal spirality back impeller sheet, its blade shape can adopt radially straight leaf, dihedral vane or arc blade, described back impeller 2 blade heights are about 2-20mm by forcing latex or liquid all to calculate from the required back pressure of discharging opening 6 safety outflows, the end play of blade and cavity 4 inwall end faces is 0.5-6mm, and this gap can be that the teflon plate 3 of 1-3mm is regulated by being pasted on thickness on cavity 4 inwalls.Described charging aperture 8 and discharging opening 6 are opened in the sidepiece and the bottom of cavity 4 respectively, and described discharging opening 6 bores are equal to or less than the cavity inner wall diameter, and its opening shape is circle, square opening shape or oblateness; Described charging aperture 8 is looked the difference of medium, can enter water, oils or the silica gel lipid of pressure, also can not enter water or oil.When the motor (not shown) drives axle 5 rotations, rotor 1 rotates and drives back impeller 2 with described axle 5 and rotates with described rotor 1, after described back impeller 2 rotates, can form negative pressure by back impeller 2, the discharging opening cracking pressure is reduced to 0-0.3Mpa, axle envelope place pressure is-0.5-0Mpa that the blade place of wherein said back impeller 2 rotates the buffer brake of end of blade place, back formation more than or equal to the discharging opening cracking pressure, thereby forces latex or liquid to flow out safely on request from discharging opening; After described back impeller 2 rotates, making latex or liquid is zero or negative value at axle envelope place pressure, at the atmospheric pressure in the external world, axle envelope place greater than latex or liquid pressure at axle envelope place, thereby make latex or liquid that can not from axle joint seal crack, leak, reach packingless effect.
Embodiment two:
As shown in Figure 2, in the present embodiment, teflon plate 3 is not drawn, different is with embodiment one, back impeller 2 is designed to independently impeller, be loaded on the axle 5, and with rotor 1 rotation, the two sides blade of impeller all is designed to the centrifugal blade that throws away, the core of described back impeller 2 blades design is that the pressure that place, blade outer is formed is zero or negative value, the pressure that place, described blade outer forms is equal to or less than extraneous atmospheric pressure, thereby makes latex or liquid that can not leak from axle joint seal crack, reaches packingless effect.Simultaneously, discharging opening 6 cracking pressures of back impeller 2 blade outers place's back pressure and cavity 4 reach balance, thereby force latex or liquid to flow out safely on request from discharging opening.
Embodiment three:
As shown in Figure 3, in the present embodiment, teflon plate 3 is not drawn, different is that independently back impeller 2 is two or more impellers, is loaded on the axle 5 with embodiment two, and with rotor 1 rotation, this structure helps to form higher buffer brake at the end of blade place, and sealing effectiveness is better, can be in order to seal some special liquid or gases.
Among three above-mentioned embodiment, according to medium of being sealed up for safekeeping and technological requirement, can add or not add centrifugal pendulum hammer lugs 7 among all embodiment, above-mentioned all embodiment are generally used for vertical emulsifier or horizontal emulsifier and pump equipment.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
