Definitions

  • the invention relates to a feed pump which is driven by a motor and especially used with a wet grist in beer production can.
  • a feed pump that is driven by a motor and for transmission the driving force uses a bevel gear, for example from the GB 1,065,194 A known.
  • the pump also has a shaft-driven one Pump mechanism on, with a first bevel gear around the same axis rotates as the shaft and is driven by a first transmission means and a second bevel gear driven by a second transmission means from the engine becomes.
  • the material to be shot is mixed with water and fed to the grinder of a wet grist mill.
  • the grinder of a wet grist mill There is the thing to be crushed Good e.g. grind between two rollers.
  • the crushed good is below the grinder with the help of a feed pump.
  • the crushed material is extracted using an eccentric screw pump, arranged at the outlet end of the wet grist mill and serves as a feed pump.
  • an eccentric screw pump shows a high due to the abrasive behavior of the mash Wear and is therefore maintenance-intensive.
  • feed pump which is at the outlet end of a wet grist mill can be attached, closes below the suction port, the e.g. can be flanged to the wet grist mill, a pump housing in to which an impeller pumps the material to be pumped from above onto the impeller Transport through a pressure port presses.
  • the impeller is at the top End of a driven shaft attached.
  • the shaft of the feed pump is by means of a employed bearing stored in a bearing block, which is attached to the pump housing from below is attached.
  • the lower end of the shaft protrudes downwards from the bearing housing out.
  • a pulley is attached to this lower end of the shaft, which is driven by an electric motor to the shaft and a belt to set the pump impeller in rotation.
  • the height is essentially due to the length of the Bearing blocks for the vertical shaft with the one at the lower end Pulley determined. If you use commercially available bearings, So those that can be mass-produced have bearings use with a certain minimum length, which is the overall height of the entire Pump unit would enlarge. In order to get a lower overall height therefore specially designed bearings are used, which are relatively expensive.
  • the object of the invention is to provide a Specify feed pump, which is manufactured more cheaply despite the low overall height can be used as well-known feed pumps and in particular for use with a Wet grist mill is suitable.
  • the feed pump according to the invention has the drive transmission from the engine Feed pump on a bevel gear.
  • a bevel gear is also inexpensive and robust and is also subject to much less wear and tear than a belt drive.
  • the feed pump comprises a pump impeller with an essentially vertical, driven shaft that is rotatably mounted.
  • a pump impeller enables a robust and failure-prone construction. This can be done simply be provided that a first bevel gear of the bevel gear by the same
  • the axis is rotatable like the shaft and the shaft via a first transmission means drives and a second bevel gear of the bevel gear via a second transmission means is driven by the engine.
  • the first transmission means for transmitting the Driving force on the shaft is a hollow shaft which is connected to the first bevel gear and rotated by it, the shaft with a collar on the top End face of the hollow shaft rests. At the other end of the shaft, you can use the shaft be attached to a shaft nut. This is a safe and precise storage the shaft is guaranteed by the axial forces that occur during pump operation occur optimally.
  • the bevel gears are advantageously with axes perpendicular to one another arranged. Such an arrangement enables an optimal reduction in Height of the feed pump, since the motor can be mounted essentially horizontally can.
  • first transmission means for transmitting the driving force to the shaft an element includes the driving force of the hollow shaft by positive locking on the shaft wearing.
  • Such an arrangement is very simple and can be easily, e.g. for cleaning purposes, disassemble and reassemble.
  • positive locking transmission is robust and not susceptible to interference.
  • the element for transmitting the driving force is on the shaft a key.
  • the second transmission means comprises Transmission of the driving force from the motor to the second bevel gear of the bevel gear a drive shaft with a detachable connection. This way easily disconnect the bevel gear from the engine. In addition, such a releasable Connection easy replacement of the bevel gear.
  • the motor for driving the bevel gear is simply an electric motor, which is connected to the bevel gear housing via a flange connection.
  • a wet grist mill with which the feed pump according to the invention is advantageously used can be comprises a grinder, which consists of two rollers 31, 32 which in a container 30 are arranged.
  • the container 30 has a shot feed 34.
  • the pump housing closes at the suction nozzle 17 1 in which the pump impeller 2 rotates.
  • the pump impeller 2 is on one Shaft 9 mounted, which is arranged vertically. 16 denotes the pressure port, through which the impeller removes the crushed material.
  • the pump housing 1 is from completed below with a pump base plate 13, which is made using a flange 3 is attached to the pump housing 1.
  • the pump room is with the help of a shaft seal 5 on the implementation of the shaft the pump base plate is sealed off from the space in the spacer lantern 4.
  • the shaft 9 has a shaft collar 24 which a hollow shaft 18 rests.
  • the pump shaft extends below the shaft collar 24 9 in this hollow shaft 18 and is via a key 7 with the hollow shaft in Positive engagement.
  • a first bevel gear 20 with the same axis as the shaft 9 or the hollow shaft 18 is attached to the outer periphery of the hollow shaft 18.
  • the first bevel gear 20 is located in the upper area of the hollow shaft near the adapter flange 6.
  • a second bevel gear 19 is in engagement with the first bevel gear 20, which has a horizontal axis.
  • the second bevel gear 19 is on an axis 22 driven by an electric motor 12.
  • the axis 22 is detachable at a point 21 designed. Junction 21 may e.g. be a plug lock.
  • the electric motor 12 is with the help of a flange 15 on a flange 14 of the bevel gear attached and supported by brackets 23.
  • Both the bevel gear 8 and the shaft 9 can be mass-produced, commercially available components.
  • the bevel gear 8 is easily replaceable.
  • the electric motor 12 can be started remove the flange connections 14, 15 so that the bevel gear only is still attached to the spacer bracket 4 by the adapter flange 6. Doing so the shaft 22 is released at the connection 21. Allows loosening this adapter flange a simple pulling off the bevel gear down, because between the Shaft 9 and the hollow shaft 18 of the bevel gear only connect over the key 7 is made. In the operating state, the shaft 9 is not at all or only slightly down over the bevel gear. By the lying electric motor, the The bevel gear enables a low overall height.
  • the modular structure with a robust bevel gear represents an economical one Possibility to drive the shaft of the feed pump according to the invention.
