Abstract
The utility model relates to a semi-balance seal structure of a pressure drum filter, which is characterized by comprising a pressure cover connecting pipe, a piston plate connecting pipe, a flexible connecting pipe, hoops, a pressure cover, a piston plate and an abrasion-resisting seal plate. Sealed through holes are additionally arranged on the pressure cover and the piston plate, and through holes are additionally arranged at corresponding positions on the abrasion-resisting seal plate. The piston plate connecting pipe is connected to the piston plate. The flexible connecting pipe is fixed on the piston plate connecting pipe through one hoop. The pressure cover connecting pipe is connected to the pressure cover. The flexible connecting pipe is then fixed on the pressure cover connecting pipe through another hoop, and a pneumatic pipeline is connected to the abrasion-resisting seal plate. The semi-balance seal structure of a pressure drum filter has the advantages that the additional pneumatic passage leads compressed air into a sealed drum filtering area, value of the compressed air is half of a pressure difference between a front area and a rear area, and accordingly sealing effect can be achieved only by halving contact pressure of the abrasion-resisting seal plate, and sealing conditions are improved.
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; Wherein discharging and the blowback of filter cloth washing band all the other be the pressure area; Sealing between these zones is maximum with the pressure reduction in pressure area and blowback district, is prone to cause leakage.Traditional encapsulating method adopts cylinder to promote the sealing wearing plate circumferential zones is sealed.Because the contact pressure that the bigger needs of pressure reduction of sealing provide the sealing wearing plate to be higher than pressure reduction reaches the effect of sealing, makes the sealing wearing plate stressed fast than galling.
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 half balance 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 half balance hermetically-sealed construction of the rotary drum filter that pressurizes; It is characterized in that: comprise gland adapter, piston plate adapter, hose connector, anchor ear, gland, piston plate, sealing wearing plate; On gland and piston plate, increase the sealing thread through hole, increase through hole in sealing wearing plate relevant position; The piston plate adapter is connected on the piston plate; With anchor ear hose connector being fixed on piston plate takes over; The gland adapter is connected on the gland; With anchor ear hose connector is fixed on gland again and takes over, be to seal wearing plate and connected pneumatic circuit.
The advantage of utility model is: increase by one road pressure channel toward being fed compressed air by in the rotary drum filtration zone that seals; Its compressed air value is 1/2nd of zone, a front and back pressure reduction; Can make sealing wearing plate contact pressure drop by half can reach sealing effectiveness like this, improve air-proof condition.
Description of drawings
Accompanying drawing 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, the utility model structure is made up of gland adapter 1, piston plate adapter 2, hose connector 3, anchor ear 4.
On gland 5 and piston plate 6, increase the sealing thread through hole, increase through hole in sealing wearing plate 7 relevant positions; Piston plate is taken over 2 to be connected on the piston plate 6; With anchor ear 4 hose connector 3 being fixed on piston plate takes on 2; Gland is taken over 1 to be connected on the gland 5; With anchor ear 4 hose connector 3 being fixed on gland again takes on 1.
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.
