Definitions
- the invention relates to a material feed container for two-cylinder pumps for the pressure delivery of thick matter with a preferably upward-facing material feed opening, with two openings on the end wall, which lead to the delivery cylinders, and one on the end wall against the end wall ⁇
- Above rear wall arranged, leading to a delivery line opening, and with an egg in the inside of the container, alternately pivotable in front of the pump-side openings and connecting them to the delivery line, one that can be pressed under the action of the delivery pressure against the pump-side openings and automatically adjusts pump-side sealing and wear ring-carrying swivel tube.
- two outlet-side openings diametrically opposite each of the pump-side openings are arranged in the rear wall, and that the swivel tube designed as a straight through-tube alternately in front of the two outlet-side openings with a connection being established the diametrically opposite opening on the pump side in each case can be pivoted and carries an automatically adjustable outlet-side sealing and wear ring under the action of the delivery pressure against the outlet-side openings.
- the outlets on the outlet side can optionally be routed to two separate pressure delivery lines or via a downpipe to a common delivery line.
- a swivel pipe 34 designed as a straight through tube, which can be swiveled with its two ends alternately in front of one and the other pair of pumps and outlets on the outlet side via a swivel shaft 36 and two plunger cylinders 38.
- the delivery cylinder connected to the associated pressure port 32 via the swivel tube 34 always works with the delivery of the goods to be conveyed in it Pressure stroke, during which the delivery cylinder 26, which is open to the interior of the material feed container 10, operates in the suction stroke by sucking in conveyed material.
- the invention relates to a material feed container for two-cylinder thick matter pumps with a pipe switch designed as a swivel pipe 34.
- a pipe switch designed as a swivel pipe 34.
- the swivel pipe 34 designed as a straight through pipe is swiveled alternately in front of the two pump-side and outlet-side openings 22, 28 and connects them to one another in pairs.
- the swivel tube is equipped at both ends with a sealing and wear ring 42, which can be pressed against the adjacent openings under the action of the delivery pressure and is automatically adjustable. Furthermore, the swivel tube carries at its outlet end two cover plates 40 which project radially on opposite sides and which cover outlet opening 28, which is open to the interior of the container, which reflux-closing.
