Definitions

the invention relates to a pump device with a pulsator as a drive element for a main pump head, which is located in a feed line and the working space is provided on the suction side with a check valve and the pressure side with a pressure valve.
the invention has for its object to provide a pump device of the type mentioned, which can be used for pumping aggressive fluids at high temperature, and yet operates at low cost with high reliability.
This object is achieved in that the working space of the pulsator is directly connected to the working space of the main pump head via a suspension line filled with conveying medium in such a way that the pulsator sucks oscillating conveying medium from the delivery line into the working space of the main pump head or pushes it out of the working space, and that the working space of the pulsator is connected via a vent valve with the suction side of the delivery line.
a basic idea of the invention thus lies in the fact that the pulsator acts on a main pump head, which in principle is designed like a piston pump head, but without a piston being required.
a pump head suitable for high temperatures and pressures standard component can be used, which represents an overall cost-effective alternative to the known solutions by the combination with a standard diaphragm pump, the principle of a "remote head" - pump is maintained.
the wear is further reduced by the fact that any particles present in the pumped medium do not come into contact with the workspace of the pulsator, since the liquid in the pendulum line is moved back and forth only in the scope of the pump stroke, and mixes only slightly with freshly sucked liquid.
the pulsator can be designed in membrane or tubular membrane construction as well as in piston or plunger construction. If the pulsator is a diaphragm pump, particles will not get to the membrane. Since high temperatures in the pumped medium decrease in the course of the transfer line, diaphragm pumps can be used with inexpensive plastic membranes, such as PTFE, even at high pressures and high temperatures in the delivery line. Therefore, pumping devices according to the invention are particularly well suited for the conveyance of biomass in the production of biofuel.
the inlet into the suction-side delivery line is preferably located above the ventilation valve, so that the gases escape from the working space automatically.
a forced ventilation for example with a time and / or pressure-controlled valve, be present.
the pendulum line is provided with a cooling.
the pendulum line is aligned by the diaphragm pump to the main pump head falling down. The particles thus remain in the region of the main pump head and are returned to the delivery line.
the pendulum line is provided with a sink as a receiving space for solid particles in the pumped medium. It is thus provided in the pendulum line, an area which is below the working space of the diaphragm pump, so that the particles accumulate there due to gravity and do not get into the working space of the pulsator.
the working chamber of the pulsator is acted upon by a compensating medium to compensate for leakage fade, so that a flow through the pendulum line and a migration of solid particles to the pulsator can be prevented.
a further advantageous embodiment of the invention is to arrange a separating piston in the pendulum line.
a low drive power is achieved in that a double-acting pulsator and two oppositely driven pump circuits are present, which is particularly advantageous when used in recirculation processes.
a pump device 1 has a diaphragm pump 10 serving as a pulsator, a main pump head 11 and a transfer line 12.
the main pump head 11 has an inlet 13 and an outlet 14 for installation in a delivery line whose pressure side is denoted by 5 and the suction side by 15.
On the inlet side (suction side) is a check valve 16 and the output side (pressure side) a pressure valve 17 is present.
the conveying direction is marked with arrow 6.
the main pump head 11 corresponds constructively to a pump head of a piston pump. However, he has no piston. His working space 18 is rather directly connected via the pendulum line 12 with a working space 20 of the diaphragm pump 10.
the diaphragm pump 10 is provided only with a single connection 7 for the shuttle 12. It has no pump valves. It is only a connection 8 for a vent with a vent valve 9 ( Fig. 2 ) and a connection 4 for a refill reservoir 30 (FIG. Fig. 2 ) available.
the hub causes the diaphragm pump 10 via the liquid column in the transfer line 12, the promotion in the main pump head 11th
the pendulum line 12 is filled with delivery fluid 21. It leads via a control input 22 of the main pump head 11 to the working space 20 of the diaphragm pump 10.
the pendulum line 12 is provided with a cooling, which is formed by a cooling liquid applied to the cooling jacket 23. In this way, a temperature reduction of, for example, about 360 ° C at the main pump head 11, as it typically has to be promoted bio-mass in the bio-fuel production, be made to about 100 ° C at the diaphragm pump 10.
the transfer line 12 contains the delivery liquid 21, which may also have solid particles 24, a portion 25 is present in the transfer line 12, which drops from the diaphragm pump 10 to the main pump head 11, and which opens directly into the working chamber 18 of the main pump head 11. At its lowest point the pendulum line 12 is thus at the level of the working space 18 of the main pump head 11. The solid particles 24 remain due to gravity in the working space 18 of the main pump head 11 and do not reach the working space 20 of the diaphragm pump 10. They are the pressure-side delivery line 5 supplied.
the membrane pump 10 has a membrane 26, which is hydraulically controlled via a diaphragm control chamber 27.
the membrane material is preferably PTFE. Alternatively, elastomers, metallic materials or composite materials can be used.
the diaphragm control chamber 27 is acted upon by a piston 28 which is driven by a motor 29 (FIG. Fig. 2 ) is driven.
a refilling reservoir 30 filled with a compensating medium is present, which is supplied via a controlled valve 31 (FIG. Fig. 2 ) Emits compensation medium in the working space 20 of the diaphragm pump 10.
the feeder is in Fig. 2 denoted by 32.
Fig. 2 illustrated configuration has a double-acting pulsator with two pump devices, as shown in Fig. 1 illustrated up.
the pump devices are connected in parallel in two counteracted branches A, B.
a pumping operation will be described with reference to a branch.
the pendulum line 12 and the working space 18 of the main pump head 11 are completely filled with pumped liquid.
the check valve 16 and the pressure valve 17 are closed.
each main pump head 11 with a single-acting pulsator equal or opposite directions can be controlled.
FIG. 3 is shown as a detail of a second embodiment, a portion of a pendulum line 12 '.
a separating piston 32 mounted longitudinally displaceably according to a double arrow 34 is arranged in the transfer line 12'. Any existing solid particles 24 thereby remain in a region 32 on the side of the main pump head 11 and can not reach a region 33 on the side of the diaphragm pump.
