Abstract
The utility model relates to an interval sealing structure of a pressure rotary drum filter, which is composed of a substrate, a piston gland, a plunger, a cylinder sealing piece, a pressing bolt, a gas inlet pipe, and a sealing wear-resisting plate, wherein the substrate is arranged on the sealing wear-resisting plate; the piston is arranged inside the substrate; the piston is connected with the piston gland by the pressing bolt, and the cylinder sealing piece is simultaneously pressed to seal the substrate and piston; and the gas inlet pipe is connected with the center of the piston. Compressed air enters by the gas inlet pipe, and the substrate is pushed downwards, so that the sealing wear-resisting plate and the rotary drum partition form required sealing specific pressure. The interval sealing structure has the characteristics that the cylinder structure which is easy to process and can guarantee precision is formed to push the sealing wear-resisting plate to seal the interval.
Description
Technical field
The utility model belongs to a kind of hermetically-sealed construction form of the rotary drum filter plant that pressurizes, and specifically is the circumferential interval hermetically-sealed construction in rotary drum cylindrical upward pressure district and blowback district.
Background technology
At present the pressurization rotary drum filter domestic does not still have successfully make the precedent of using, the rotary drum filter that is to pressurize of tracing it to its cause is in the pressure operation down of 0.3-0.6MPa, causes respectively turn round sliding surface and joint face sealing difficulty, easy leakage can't reach instructions for use.And the rotary drum excircle reinforced to accomplishing in 12 a multiples filtration zone of dividing equally week when equipment moves, filter, washing, dry, discharging and filter cloth washing; Each interval can be moved under different pressures; Wherein discharging and the blowback of filter cloth washing band all the other be the pressure area, need between these zones the sealing.Traditional encapsulating method is provided with rectangle cylinder promotion sealing wearing plate circumferential zones is sealed in the whole zone of sealing.Because the manufacture difficulty of machinery, large-scale square cylinder is difficult to reach sealing effectiveness, makes that sealing effectiveness is poor between the zone.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of improved novel interval hermetically-sealed construction is provided.
The above-mentioned technical problem of the utility model is able to solve through following technical proposals:
A kind of interval hermetically-sealed construction of the rotary drum filter plant that pressurizes is made up of substrate, piston gland, plunger, cylinder seal spare, hold-down bolt, air inlet pipe, sealing wearing plate; On the sealing wearing plate is substrate; Piston is set in the substrate; Piston is connected on the piston gland through hold-down bolt, simultaneously clamping cylinder seal hermetic sealing substrate and piston; Centre connects air inlet pipe.Compressed air promotes the seal pressure that substrate makes sealing wearing plate and rotary drum dividing plate formation needs downwards after through the air inlet pipe air inlet.
Sealing wearing plate, substrate and piston gland remove movable space and fill up compartment.
Isolate in the frame and place substrate on the sealing wearing plate; Several circular counter bore are set on the substrate form several cylinder bodies; The corresponding circle column piston is set on the piston gland; Utilize piston gland to compress cylinder seal spare packed-piston and cylinder body on the plunger circumference, air inlet pipeline is set at the plunger center connects source of the gas through piston gland.
The characteristics of the utility model are: form the air cylinder structure that is prone to processing assurance precision like this and promote between sealing wearing plate seal area.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, do further bright specifically to the technical scheme of the utility model.Embodiment: referring to accompanying drawing 1, the utility model structure is made up of substrate 1, piston gland 2, piston 3, cylinder seal spare 4, hold-down bolt 5, air inlet pipe 6, sealing wearing plate 7; Above-mentioned part is seated in the compartment 8.
On the sealing wearing plate 7 is substrate 1; Piston 3 is set in the substrate 1; Piston 3 is connected on the piston gland 2 through hold-down bolt 5, simultaneously clamping cylinder seal 4 hermetic sealing substrates 1 and piston 3; Piston 3 centers connect air inlet pipe 6.Compressed air promotes the seal pressure that substrate 1 makes sealing wearing plate 7 and rotary drum dividing plate 9 formation needs downwards after through air inlet pipe 6 air inlets.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all should think the protection domain that belongs to the utility model.
