| titleOfInvention | Novel feed mechanism is used in production of polyether polyol |
| abstract | The utility model discloses a novel feeding mechanism for polyether polyol production, which comprises a feeding tank, wherein a filter screen is clamped in the feeding tank, movable grooves are formed in the outer walls of two sides of the filter screen, clamping blocks are connected in the movable grooves in a sliding mode, clamping grooves are formed in the inner walls of two sides of the feeding tank, the clamping blocks are clamped in the clamping grooves in a clamping mode, a guide plate is welded on the inner wall of each movable groove, the clamping blocks are sleeved outside the guide plate in a sliding mode, a pull-back spring connected with the clamping blocks is welded on the inner wall of each movable groove, and a pull rod is inserted into the outer wall of the top of the filter screen. According to the utility model, the pull rod is pulled to enable the abutting cone to move upwards so as not to generate thrust on the clamping block, the clamping block is far away from the inside of the clamping groove, the filter screen is convenient to disassemble and replace from the inside of the feeding tank, water passes through the water inlet pipe and the water cavity and then is sprayed on the inner wall of the feeding tank through the spray head, water can be sprayed and cleaned on the inner wall of the feeding tank, the self-cleaning function is realized, and the influence of the residual additive on the next production of polyether polyol is avoided. |
