Material feeding container for two-cylinder thick matter pumps
The invention relates to a material feeding container for two-cylinder thick matter pumps. The material feeding container ( 24 ) has a material supply opening ( 30 ) oriented upward, two feed cylinder openings ( 34 ) arranged in the front wall ( 36 ) of the container and a transfer tube having the shape of an S-tube ( 42 ), which is arranged inside the container with its input end ( 48 ) swiveling in an alternating manner in front of the feed cylinder openings ( 34 ) and mounted on the output side in a feed-through opening ( 46 ) of the rear wall ( 38 ) of the container that is arranged above the feed cylinder openings. A pressure pipe ( 40 ) is connected to the outer side of the rear wall ( 38 ) of the container, the output side ( 44 ) of the S-pipe ( 42 ) leading into said pressure pipe. According to the invention, a maintenance opening ( 56 ) is arranged on the rear wall ( 38 ), which is formed by an opening defined by a peripheral edge ( 58 ). The maintenance opening ( 56 ) can be closed with a cover plate ( 60 ), which has a top cover plate part ( 64 ) that is oriented perpendicular to the swiveling axis ( 50 ) of the S-pipe ( 42 ) and includes the feed-through opening ( 46 ) for the S-pipe ( 42 ) and a bottom cover plate part ( 68 ) that forms an inclined bottom part and that is connected to said top part substantially parallel to an S-pipe segment ( 66 ) extending obliquely downward.
1. A material feeding container for two-cylinder thick matter pumps, with an upwardly oriented material input opening ( 30 ), two feed cylinder openings ( 34 ) arranged in the front wall ( 36 ) of the container, and a transfer tube having the shape of an S-tube ( 42 ), which is arranged inside the container with its input end ( 48 ) swiveling in an alternating manner in front of the feed cylinder openings ( 34 ) and mounted on the output side in a feed-through opening ( 46 ) of the rear wall ( 38 ) of the container that is arranged above the feed cylinder openings and in communication with a pressure pipe ( 40 ) is connected to the outer side of the rear wall ( 38 ) of the container, the output side ( 44 ) of the S-pipe ( 42 ) communicating with said pressure pipe, thereby characterized, that a maintenance opening ( 56 ) is arranged on the rear wall ( 38 ), which is formed by an opening defined by a peripheral edge ( 58 ), that the maintenance opening ( 56 ) can be closed with a cover plate ( 60 ), which has a top cover plate part ( 64 ) that is oriented perpendicular to the swiveling axis ( 50 ) of the S-pipe ( 42 ) and includes the feed-through opening ( 46 ) for the S-pipe ( 42 ) and a bottom cover plate part ( 68 ) that forms an inclined bottom part and that is connected to said top part substantially parallel to an S-pipe segment ( 66 ) extending obliquely downward.
2. The material feeding container according to claim 1 , wherein the peripheral edge ( 58 ) of the service opening includes an upper flange part ( 70 ) for flange connecting to the upper cover plate part ( 64 ), which is oriented in a plane perpendicular to the pivot axis ( 50 ) of the S-pipe ( 42 ) and which joins below a lower flange part ( 72 ) for flange connection to the lower cover plate part ( 68 ), which is oriented in a plane substantially parallel to the diagonally extending S-pipe segment ( 66 ).
3. The material feeding container according to claim 1 , wherein on the outer side of the upper cover plate part ( 64 ), towards the side besides the through-feed opening ( 42 ) elements are provided for the releasable attachment of the pressure pipe ( 40 ).
4. The material feeding container according to claim 3 , wherein a part of the securing element is a pivot mount ( 76 ), on which the pressure pipe ( 40 ) is able to pivot relative to the through-feed opening ( 46 ) about a vertical axis.
5. The material feeding container according to claim 4 , wherein one of the securing elements is a screw-hole ( 78 ) or a securing bolt for securing the pressure pipe ( 40 ) when pivoted into place in front of the through-feed opening ( 46 ).
6. The material feeding container according to claim 1 , wherein reinforcing ribs ( 80 ) radiating in the direction of the cover edge are provided on the outside of the lower cover plate ( 68 ).
