NIGHT SOIL DISINTEGRATING FORCE-FEEDER

摘要

PURPOSE:To sanitarily wash down the solid material stagnated in the four corners of a storage tank and also to prevent noise and trouble by separately providing both a submergible pump and a water level detection switch and fitting an elbow to the inside of the inflow port of waste water and furthermore forming a still place in the bottom part of a storage tank. CONSTITUTION:Night soil are allowed to flow together with carrier water and introduced into a screen 7 and passed through the meshes thereof and stored in the still place 2a of a storage tank 2. When night soil and carrier water are raised to the preset water level of a water level detection switch 4, a submergible pump 3 starts to be operated and the carrier water is discharged. Simultaneously night soil and toilet paper remaining in the screen 7 are disintegrated with a cutter 8 and fall into the still place 2a and are discharged through a force-feed drainage pipe 10 by the submergible pump 3. Further waste water introduced from the inflow port 5 thereof flows in the direction opposite to the position of the water level detection switch 4 by an elbow 11. Moreover while the solid material stagnated in the corners of the storage tank 2 is washed down, it is collected in the still place 2a and therefore the solid material is not deposited. Further generation of noise is prevented and the service life of the submergible pump is prolonged.
