Definitions

  • the present invention concerns a self-cleaning press filter with an endless screw and with improved efficiency, for separating solids suspended in sewage.
  • press filters with endless screw is well known for separating solids suspended in sewage, in particular in the zootechnical field.
  • the press filters with an endless screw actually in use mainly comprise an outer framework, with an inlet for the sewage to be treated, with an outlet for the separated liquid and with an outlet for the solid, dehydrated material. It further comprises an endless screw for the feed and pressing of the solid, dehydrated material, placed in said outer framework and operated by a motor; a cylindrical sifting container with special filters, coaxially containing the endless screw, supported by the external framework.
  • the endless screw comprises a shaft wrapped by a propeller, and the end of said propeller reaches the inner side of the sifting container.
  • the sewage to be treated will be pumped inside the sifting container, where the endless screw pushes the suspended solid parts towards the outlet, while the liquid part drains through the filters of the sifting container, is collected in the outer framework, housing the container, and is eliminated through the special outlet.
  • the solid material will be made compact by the push exerted by the endless screw and forms a dehydrated bung that will be ejected through the outlet.
  • Document EP 0 367 037 shows a kind of press filter with an endless screw for separating solids suspended in sewage, in which the bung of solid dehydrated material is ejected through an annular, cylindrical fissure existing between the shaft of the endless screw and the sifting container.
  • the bung of solid material has a hollow cylindrical shape, is less compact near the shaft of the endless screw and tends to favour a possibility of escape for the liquid, that may hole the bung and drain from the ejection outlet for the solid material; it is not easy to restrain the shaft of the endless screw at its end projecting from the opening of the outer framework, and therefore it is easily subject to radial bending; furthermore, if the sewage to be treated is poor in solids, the machine will not be able to realize the bung of solids at the start and will request the realization of an artificial bung.
  • said disk is connected with movable counterweights or elastic means which dete ⁇ nine its pressing force onto the bung of solid material coming out from the opening.
  • the sifting container is supported and works inside the framework with its own axis inclined upwards with respect to the sense of feeding of the solid material, so as to favour the draining of the liquid part.
  • the shaft of the endless screw has an end with a polygonal section and is connected with the shaft driven by the motor by means of a tlireaded coupling. Therefore, it is possible to disassemble the machine simply by blocking, with a special key, the end with the polygonal section of the shaft of the endless screw, inverting the direction of rotation of the motor for unscrewing the tlireaded coupling and taking out of the outer framework the endless screw and the sifting container.
  • Such a realization allows to form a bung of solid, homogenous, dehydrated material, without preferential breaking ways, of a nearly perfect cylindrical shape and very compact, even if sewage is treated poor in suspended solids, and without the need of realizing an artificial bung of filtered solid material when starting the machine; furthermore, it allows an effective ejection of the solid material and a high degree of separation of the phases; at last, it allows an easy disassembling of the machine for servicing and internal cleaning.
  • One disadvantage of mentioned solution consists in that the adjusting of the pressing force of said antagonist disk, performed by means of movable weights or elastic elements like e.g. springs, is uncomfortable, requests to put ones hands at the opening of the separator and may be perfo ⁇ ned only with the machine standing still.
  • a further disadvantage consists in that the disassembling of the machine - even if it has been simplified by above-mentioned realization - makes the cleaning operations rather long and expensive.
  • Italian Utility Model No. CR 99000013 of the same applicant a further improvement has been described, mainly consisting of the operating of the antagonist disk by means of a hydraulic or pne natic operating means and of the adoption of a closing plate provided with a hole closed by a removable cap, on the outer framework.
  • the motor that operates the pressing endless screw is - in the known press filters with an endless screw - of electric or oleodynamic kind.
  • the latter is advantageously operated by an oleodynamic central usually comprising a pump, a distributor controlled by a lever with three positions that allows to invert the direction of rotation of the motor and for unscrewing the tlireaded connection between the shaft of the endless screw and the shaft of the motor, and a regulation valve that allows to vary the revolutions of the motor, usually between 0 and 200 per minute.
  • Said pump may be operated by an internal combustion engine or by an electric motor, or even directly through the power plug of a farm tractor.
  • the revolution speed will be regulated according to the work load of he machine and to the composition of the sewage to be treated, so as to optimise the efficiency of the press filter and to reduce the stress onto the mechanical means, specially when starting and stopping the machine.
  • the feeding of the sewage to be treated to the inlet of the outer framework takes place through a feeding pipe usually connected by means of a T-shaped link to a overflow pipe, that discharges the excess sewage and sends it back to the raising well.
  • the regulation of the inlet capacity to the press filter and of the capacity discharged from the overflow pipe takes place by means of a valve of known kind, with manual or controlled operating, mounted onto the overflow pipe.
  • the press filters with endless screw of the known kind still show some disadvantages. Due to their one-way preferential direction, the solid particles tend to get stuck between the filtering meshes and to fo ⁇ n encaistations that worsen the filtering efficiency and make servicing and filter cleaning necessary, which requires the disassembling of the endless screw and are therefore long lasting and expensive; ftirthermore, the oleodynamic motor has proved to be little flexible in the regulation of the speed and of the direction of rotation and does not allow an optimisation of the efficiency of the press filter according to the different working conditions; then, the oleodynamic motor has a low efficiency, in particular during the working with a partial load, with a following high energy consumption in relation to the work performed by the machine.
  • a further inconvenience consists in that the pressure of the sewage inside the sifting container may be subject to sudden changes or to sudden increase which detennine a reduction of the efficiency of the machine and high stress rates onto the mechanical parts.
  • a ftirther disadvantage consists in that possible front or back movements of the antagonist disk, placed before the outlet of the solid material - due to variations of the density of the treated material - may cause a variation of the pressure in the hydraulic or pneumatic means for operating the disk. Such effect implies a variation of the pressing force applied by said disk to the solid material to be ejected, with negative effects onto the homogeneity of the solid ejected product and of the global efficiency of the machine. It is the aim of the present invention to eliminate above-mentioned inconveniences.
  • the aims set forth are reached by means of a self-cleaning press filter with an endless screw and with improved efficiency, for separating solids suspended in sewage according to the present invention, of the kind comprising:
  • an outer framework provided with an inlet for the sewage to be treated, with an outlet for the separated liquid and an outlet for the solid dehydrated material;
  • said endless screw comprises a shaft wrapped by a propeller, and the end of said propeller reaches nearly the inside side of the sifting container
  • sad motor means for operating the endless screw comprise an electric engine connected with programmable control means that may be separately operated, and which may invert and restore the direction of rotation of said endless screw during the work of said press filter.
  • Said control means advantageously comprise an inverter device, a potentiometer for regulating the rotation speed and a timer which allows controlling the variation of the direction of rotation of the endless screw at determined time intervals.
  • a counterweight automatic valve with adjustable intervention is mounted onto the overflow pipe.
  • a hydraulic operating means comprising a stem connected to the disk sliding in a cylinder connected to a circuit provided with special compensation means, advantageously consisting of a pressure accumulator, which maintain constant the pressure inside said circuit.
  • the motor means are controlled by a device that varies the motor's speed (inverter), for avoiding absorption peaks of the electric engine at the start and the following stresses on the mechanical means.
  • inverter a device that varies the motor's speed
  • the advantages obtained by means of the present invention are mainly the following: - during the working of the machine, it is possible to periodically and for detemiined time intervals invert the direction of rotation of the endless screw, which thus exerts a scraping and cleaning action of the filters, reducing the encmstations due to the one-way motion of the solid particles;
  • the possibility of preventing sudden pressure changes inside the sifting container and to maintain constant he pressing force of the antagonist disk allows to improve the efficiency of the machine, the production constancy, the filtering efficiency and the homogeneity features of the ejected solid product;
  • Figure 1 shows a lateral view and a partial section of a press filter with an endless screw for separating solids suspended in sewage according to the present invention.
  • Figure 2 shows in detail the working of the automatic counterweight valve with adjustable intervention, mounted onto the overflow pipe of the machine.
