NIGHT SOIL DISINTEGRATING FORCE-FEEDER

摘要

PURPOSE:To prevent spallation fragments from being stagnated in the corner of a storage tank by providing a recessed part on the bottom face thereof and installing a submergible pump and a water level detection switch therein and providing a gradient toward the recessed part from the four corners of the bottom face. CONSTITUTION:Night soil is allowed to flow together with carrier water from a water closet and introduced into the inside of a screen 7. This carrier water passes through the meshes of a screen 7 and falls into a storage tank 2 and the water level thereof is raised. When the water level is raised higher than the set water level of a water level detection switch 4, a submergible pump 3 is operated and the carrier water starts to be discharged. Simultaneously night soil and toilet paper remaining in a screen 7 are disintegrated with a cutter 8. When these are made smaller than the mesh of the screen 7, these fall into the storage tank 2 together with the carrier water and are force-fed into a force-feed drainage pipe 10 by the submergible pump 3. Herein the spallation fragments of night soil and toilet paper fall into a storage tank 2 and are dispersed into the carrier water. This carrier water dispersed therewith descends on a gradient face 2c and a sharp slope 2b and collects in a recess 2a and is sucked by the submergible pump 3 and discharged. Therefore the spallation fragments do not remain in the corners of the storage tank 2.
