Description

The anti-oil sealing device of a kind of stirring system
Technical field
The utility model relates to Mixing Machine field, especially a kind of stirring shaft seal for stirring system.
Background technique
In the industry such as food, medication chemistry, stirring system is one of equipment the most often used, and the general structure of stirring system is that stirring shaft is vertically arranged in tank body, and tank body is stretched out through cover in the top of stirring shaft, speed reducer is arranged on the top of stirring shaft, and stirring shaft is connected with motor by speed reducer.In stirring system working procedure, if speed reducer breaks down, occur Leakage, now machine oil along stirring shaft to downstream in tank body, can cause the material in tank body to be polluted, has a strong impact on food, medicine health and safety.But along with drug and food is to the strict demand of production process, do not allow that the impurity such as speed reducer machine oil enter material system, so just require to have inside and outside stirring system tank the sealing configuration that is good.
Model utility content
The technical problems to be solved in the utility model is to provide the anti-oil sealing device of simple, the practical stirring system of a kind of structure; for the stirring system favorable sealing property of low pressure, normal pressure container; when speed reducer generation lubricating oil leakage, guarantee that machine oil can not enter tank body, avoid material and pollute.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
The anti-oil sealing device of a kind of stirring system, it comprises the seal tank being fixedly installed on cover end face, described seal tank is set on stirring shaft, the groove of the annular for receiving fluids is offered in the upper-end surface of seal tank, above seal tank, back-off arranges oil blocking cover, described oil blocking cover installs and is fixedly installed on stirring shaft, and the bottom of oil blocking cover is suspended in the groove of seal tank, the top of oil blocking cover and stirring shaft joint is stacking arranges sealer.
Further improvement of the utility model is, the end face of described sealer arranges the low inside and high outside oblique shoulder facilitating the machine oil of speed reducer dirty.
Further improvement of the utility model is, runs through the drain pipe arranged for discharging liquid in groove bottom the outer side wall of described seal tank.
Further improvement of the utility model is, the bottom surface of described seal tank is weldingly fixed on cover end face.
The beneficial effect adopting technique scheme to produce is:
The utility model structure is simple, and easy for installation, favorable sealing property, is applicable to the stirring system in low pressure, normal pressure container.When speed reducer generation lubricating oil leakage, machine oil is along stirring shaft to downstream to sealer place, and machine oil can flow on oil blocking cover along sealer afterwards, is finally flowed in the groove of seal tank by the guiding of oil blocking cover.So just guarantee that machine oil can not enter tank body by stirring shaft, avoid and the material in tank body is polluted, ensure quality of product.
The end face of sealer arranges oblique shoulder, play the guiding role, and facilitates machine oil smoothly to downstream to oil blocking cover.The outer side wall of seal tank runs through and arranges drain pipe, and the liquid in convenient release groove, ensures to produce smoothly.

In figure, each label is expressed as: 1, speed reducer, and 2, stirring shaft, 3, seal arrangement, 3-1, oil blocking cover, 3-2, set screw, 3-3, water sealing liquid, 3-4, seal tank, 3-5, drain pipe, 4, sealer, 5, cover.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The anti-oil sealing device of a kind of stirring system, its mounting point in stirring system as shown in Figure 1, is positioned at the end face of the below of speed reducer 1, cover 5, and is set on stirring shaft 2.
The structure of the anti-oil sealing device of described stirring system as shown in Figure 2, comprises oil blocking cover 3-1, seal tank 3-4 and drain pipe 3-5.The machine oil that described oil blocking cover 3-1 leaks for accepting speed reducer, and machine oil is guided in seal tank 3-4.Described drain pipe 3-5 is used for the liquid in discharge water sealing groove 3-4.
Described seal tank 3-4 center arranges through hole, is set on stirring shaft 2 by through hole, and central through bore and the stirring shaft 2 of seal tank 3-4 can be set to transition fit, when preventing stirring shaft 2 from rotating and seal tank rub.Seal tank 3-4 is arranged on the end face of cover 5 by being welded and fixed, also can be fixed by other Placements such as riveted joint, bolt connections.Offer the groove of an annular downwards in the upper-end surface of seal tank 3-4, the path of groove is greater than the central through bore aperture of seal tank 3-4, and described groove is used for receiving fluids, and described liquid can be water sealing liquid 3-3 or other liquid stream material.
Described oil blocking cover 3-1 is positioned at the top of seal tank 3-4, is equipped with seal tank 3-4 back-off.The sidewall of oil blocking cover 3-1 runs through and is provided with set screw 3-2, by set screw 3-2 and stirring shaft 2 fixedly sleeved, the center hole of oil blocking cover 3-1 and the external diameter of stirring shaft 2 are set to interference fit, prevent machine oil along the slit flow between oil blocking cover 3-1 and stirring shaft 2 in tank body.For blocking the machine oil that speed reducer is revealed smoothly, prevent machine oil from flowing into tank body along stirring shaft, be provided with sealer 4 the end face of oil blocking cover 3-1 is stacking, the end face of described sealer 4 arranges the low inside and high outside oblique shoulder facilitating the machine oil of speed reducer dirty.A blind hole is upwards offered in the bottom surface of oil blocking cover 3-1, and being connected with center hole becomes shoulder hole.The bottom width of oil blocking cover 3-1 is corresponding with the recess width of groove 3-4, and the bottom suspension of oil blocking cover 3-1 is stretched in the groove of seal tank 3-4.
Described drain pipe 3-5 run through be arranged on seal tank 3-4 outer side wall on, be positioned at the bottom of outer side wall, one end of drain pipe 3-5 is connected with the groove of seal tank 3-4, and the other end stretching out seal tank 3-4 arranges valve, facilitates the liquid in control discharge groove.
Working principle of the present utility model is:
When the speed reducer generation lubricating oil leakage of top, with sealant sealing between oil blocking cover and stirring shaft, prevent machine oil along the slit flow between oil blocking cover and stirring shaft in tank body.Oil blocking cover is fixedly connected with by set screw with stirring shaft, with stirring shaft synchronous axial system.Oil blocking cover back-off enters seal tank, in the groove of seal tank, add water sealing liquid, and the bottom of oil blocking cover can seal by the liquid level of water sealing liquid.
Leak once speed reducer generator fry dried food ingredients is raw, machine oil flows to sealer place downwards along stirring shaft, is cut stifled by sealer and oil blocking cover, and in the groove that oil blocking cover flows into seal tank, the material in tank body and external environment condition are separated by the water sealing liquid in groove.After in the groove that machine oil is collected at seal tank, bottom the outer side wall of seal tank, a blowdown valve is installed, by valve by the fluid removal in groove.
