Background
The treatment machine is widely applied to the field of harmless treatment, and can sterilize, hydrolyze and dry animal carcasses and byproducts to be treated. The chemical processing machine generally takes saturated steam as a heat source, treats animal carcasses and related animal products under the action of high temperature and high pressure by introducing high-temperature saturated steam into a container interlayer, integrates chemical processing and drying, and has the characteristics of large single-batch treatment capacity and safe and thorough sterilization effect. Packing is mostly adopted for sealing in the traditional chemical manufacturing machine, and the packing is a dynamic sealing device which generates pressing force between the packing and a rotor and between the packing and a packing gland through bolt pre-tightening. Because the inside high temperature of change system machine, high pressure and the inside medium contain the complicated operating mode of solid, steam, grease, traditional packing seal often begins to seal well when moving, nevertheless uses a small segment time after let out leakage quantity just constantly increase, the work of adjustment packing gland and change packing condiment is also frequent gradually, if not in time maintaining, causes equipment to reveal easily, sealed effect is unsatisfactory. Meanwhile, the traditional packing sealing device and the bearing device of the forming machine adopt a separated design, and the sealing device and the bearing device are slightly eccentric, so that packing and a rotating shaft are easily worn eccentrically, packing is easily abraded excessively, and the sealing device fails. Meanwhile, the friction between the packing and the rotor causes the reduction of the effective power of the motor, the electric energy consumption is usually 5 to 10 percent, and the waste of the electric energy is caused.

The utility model discloses a realize through following technical scheme: the utility model provides an integration mechanical seal structure for changing system machine pivot, includes the suit at the epaxial axle sleeve of pivot, and the axle sleeve is connected with the pivot transmission, is equipped with bearing assembly and mechanical seal subassembly on the axle sleeve circumference, and mechanical seal subassembly's wear ring passes through the screw and installs on the axle sleeve, and bearing assembly and mechanical seal subassembly's outside cover is equipped with the supporting seat, and supporting seat and axle sleeve fixed connection.
Furthermore, the end part of the shaft sleeve is fixedly provided with a locking disc, the locking disc is provided with a plurality of bolt holes, and the locking disc is fixed with the rotating shaft through bolts.
Furthermore, the supporting seat sequentially comprises a supporting sleeve I, a supporting sleeve II, a supporting sleeve III and a supporting sleeve IV along the axial direction from one end close to the locking disc; the support sleeve I and the shaft sleeve are clamped together through a side plate, the bearing assembly is sleeved between the support sleeve I and the shaft sleeve, and the bearing assembly is axially limited by an inner side journal of the support sleeve I and an inner side journal of the support sleeve II respectively; the mechanical seal assembly I is sleeved between the support sleeve II and the shaft sleeve, the mechanical seal assembly II is sleeved between the support sleeve III and the shaft sleeve, the lip seal is sleeved between the mechanical seal assembly II and the shaft sleeve, the support sleeve IV is sleeved on the outer circumference of the lip seal, and the support sleeve I, the support sleeve II, the support sleeve III and the support sleeve IV are sequentially fixed into a whole through bolts.
The utility model has the advantages that: compare in traditional packing sealing, structure before this application has been simplified has guaranteed to change the inside reliable sealed of system machine, has avoided revealing of harmful substance, keeps changing the outside cleanness of system machine. The design after optimization has the greatest benefits that the frequency of manually compressing packing seasonings and replacing packing materials is reduced, the maintainability of equipment is greatly improved, and meanwhile, the service life of the spindle of the chemical making machine is prolonged due to the fact that the friction between the packing materials and the rotating shaft is reduced.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure, the seal ring comprises a shaft sleeve 1, a shaft sleeve 2, a bearing assembly 3-1, a mechanical seal assembly I, a mechanical seal assembly 3-2, a mechanical seal assembly II, a mechanical seal assembly 4, a support seat 4-1, a support sleeve I, a support sleeve 4-2, a support sleeve II, a support sleeve 4-3, a support sleeve III, a support sleeve 4-4, a support sleeve IV, a support sleeve 5, a locking disc 6 and a lip seal.
Detailed Description
The invention will be further explained below with reference to the drawings and examples.
As shown in fig. 1, an integrated mechanical seal structure for a rotating shaft of a chemical processing machine comprises a shaft sleeve 1 sleeved on the rotating shaft, the shaft sleeve 1 is in transmission connection with the rotating shaft, a bearing assembly 2 and a mechanical seal assembly are arranged on the outer circumference of the shaft sleeve 1, a wear-resistant ring of the mechanical seal assembly is installed on the shaft sleeve 1 through a screw, a support seat 4 is sleeved on the outer sides of the bearing assembly 2 and the mechanical seal assembly, and the support seat 4 is fixedly connected with the shaft sleeve 1. The pivot drives mechanical seal subassembly synchronous rotation, and there is not friction between mechanical seal subassembly and the commentaries on classics pivot almost, and its frictional power only is about 10% with size packing seal, and mechanical seal subassembly and bearing subassembly 2 fasten into the integral type structure through axle sleeve 1 and supporting seat 4 simultaneously, have reduced the installation space greatly, compact structure, because a supporting seat 4 of sharing, space size guarantees that mechanical seal subassembly and bearing subassembly 2 are located same axis, and is sealed more reliable.
