Definitions

  • the invention relates to a two-cylinder high-pressure pump, the preferably parallel, axially parallel delivery cylinder of which is built up in a frame, alternately through an inlet valve housing common to them and connecting them to a prefill container or a feed line, sucking in a pasty to pulpy thick matter and pressing it out into a pressure line in the following cycle through an outlet valve housing connected to it , wherein in each valve housing each feed cylinder is assigned a positively controlled valve with a valve drive cylinder and the inlet and outlet valve drive cylinders are each arranged axially parallel to one another.
  • the two-cylinder thick matter pump according to the invention is suitable for conveying a wide variety of thick matter because of its valve system, which excludes a wear-generating short circuit between the suction and pressure chamber due to its four positively controlled valves.
  • This z. B. designed as plunger or disc seat valves and acted upon with a hydraulic pressure medium valves can control large cross-sections through which the medium to be pumped can flow, which can be designed to be aerodynamically suitable.
  • Examples of thick matter which can be pumped with two-cylinder thick matter pumps according to the invention are thermally conditioned digested sludge from sewage treatment plants, filter cakes in the food industry, in particular in the sugar industry, flotation waste in hard coal and ore mining and bentonite-cement mixtures for soil grouting.
  • the invention is based on a two-cylinder high-pressure pump known from a previously published brochure, in which the feed cylinders are arranged horizontally next to one another, so that the thick material to be fed can enter the inlet valve housing from above.
  • the inlet seats lie in a horizontal plane above the feed cylinders, while the vertically arranged inlet valve drive cylinders are arranged below the feed cylinders.
  • the exhaust valve housing is located on the front side of the intake valve housing with the horizontally arranged exhaust valve drive cylinders, which enclose the pipe of the pressure line.
  • the invention has for its object to reduce the overall height of a two-cylinder high-density pump and to improve its ease of repair, particularly in confined spaces, without the functionality of the pump being impaired.
  • this object is achieved in that the feed cylinders and the inlet and outlet valve drive cylinders are arranged one below the other in vertical planes and the prefill container or the feed line is connected laterally to the suction valve housing with a suction manifold.
  • the suction openings on one or the other side of the pump By placing the delivery cylinders on top of each other, one moves the suction openings on one or the other side of the pump; the admission of the thick matter, which is thereby made difficult, is compensated according to the invention by means of the intake manifold, the free opening of which may lie in the original plane of the intake openings of the inlet valve housing. Since the intake valve cylinders are also moved to the intake openings of the intake valve housing and the side of the housing at the same time as the intake openings are being laid, the overall height of the pump given by the upper edge of the prefilling container or the feed line can be considerably reduced.
  • the superimposed arrangement of the inlet valve cylinders and, accordingly, the intake openings controlled by them as well as the outlet valve cylinders and, accordingly, the outlet openings of the outlet valve housing belonging to them also maintain the flow-favorable design of the parts of the valve housing through which the medium flows, so that the overall functionality of the pump is not impaired .
  • the exhaust valve housing can be hinged to the intake valve housing with its hinge axis oriented parallel to the plane containing the exhaust valve drive cylinders. This articulation facilitates the opening of the outlet valve housing, which is necessary in particular to reach the seats and the shutoff bodies of the valves.
  • the intake manifold to a swing arm, the pivot axis of which is parallel to the plane containing the intake valve drive cylinders. Then namely after loosening the corresponding parts, the suction manifold can be swung to the side when carrying out assembly work on the inlet valves.
  • the two-cylinder high-pressure pump optionally to arrange the two-cylinder high-pressure pump so that the suction openings of the inlet valve housing in the conveying direction are to the right or to the left, because this can further reduce the requirements for the clearance of the pump.
  • This is expediently done in such a way that the mounting frame is symmetrical at least to a horizontal plane passing through it. Then you can arrange the pump in the mounting frame rotated by 180 ° in two positions.
  • the assemblies of the two-cylinder high-density pump 1 to be explained in detail below are constructed in a frame which, according to the exemplary embodiment shown, consists of two congruent frame members 2 and 3, which are each composed of parallel vertical sub-members 4 and 5 and, in turn, parallel horizontal sub-members 6 and 7 . These frame sections are mitred and realized with square profiles.
  • the two frame members 2 and 3 are connected to one another by crossbeams 8 and 9, which project with partial lengths 10 and 11 over the level of the front frame member 3 to the front.
  • the crossbeams 8 and 9 are optionally used to attach control and connection housings 12, 13 for the pump drive.
  • This consists of two axially parallel, hydraulically actuated drive cylinders 14, 15, which are connected to the rear of two delivery cylinders 16, 17 of the pump in alignment with the delivery cylinders.
  • the free ends of the delivery cylinders 16 and 17 end in an inlet valve housing 18, the end face of which is provided with a flange 20.
  • This can be connected to the flange 22 of an exhaust valve housing 23.
  • the exhaust valve housing carries an exhaust valve drive cylinder 24 and 25, respectively, and both cylinders 24 and 25 enclose a pipe socket 26, which forms the beginning of a pressure line, not shown.
  • the inlet valve housing 18 in turn has two inlet valve drive cylinders 27 arranged axially parallel.
  • the inlet valve housing 18 is screwed onto the crossbar extension 11 with the aid of a flap 30 formed on its upper side.
  • the inlet openings 32, 33 emerge, each of which is surrounded by four threaded blind holes 34. They can be aligned with corresponding bores 35 in the connecting flange 36 of a housing 37, which essentially comprises a 90 ° suction manifold 38.
  • the free end of the suction manifold has a connecting flange 39 with bores for connecting screws which are seated on a circle and with which a corresponding flange 40 can be fastened, which forms the lower end of a funnel-shaped prefilling container 41.
  • openings 42, 43 in the flanged part 36 of the housing 37 which can be aligned with the corresponding openings 32, 33 of the flow paths formed in the inlet valve housing 18 if, according to the illustration in FIG Flange 36 is screwed to the housing 18.
  • the housing 37 has on its side opposite the flange 36 a molded projection 44 with a fork-shaped bracket 45 for connecting a rocker 46.
  • the rocker has a front, essentially rectangular part 47, an adjoining trapezoidal part 48 and an adjoining widened part rectangular part 49.
  • the parts 47 and 49 are connected with their free ends to the vertical axis of rotation of joints 50 and 51, whose axes of rotation are vertical.
  • the axis of rotation of the joint 51 is held by a fork-shaped bracket 53, which is attached to the vertical frame member 4 of the front frame member 3.
  • the feed cylinders 16, 17 and the inlet and outlet valve drive cylinders 24, 25 and 27 are arranged vertically one above the other. If you want to get access to the seats of the valve body, not shown, you can swing the housing 37 using the rocker 46 after loosening the flange screws, which is shown in Fig.2.
  • the anchor rods 58 and 59 can be removed from their guides 60 and 61 loosen on one side of the connecting flange 22 of the exhaust valve housing 23. Then the exhaust valve housing can be stacked two
  • the described pump can also be mounted in the frame in a position pivoted by 180 ° with respect to the position shown, as a result of which the left-hand arrangement of the openings 32, 33 becomes the right-hand arrangement.
