Excrement solid-liquid separation and drying integrated device

Abstract

The invention discloses an excrement solid-liquid separation and drying integrated device, and relates to the technical field of sewage treatment devices matched with toilets or urinals. The technicaldefect that an existing closestool or urinal needs to be flushed with a large amount of clean water after being used is overcome. The device comprises a threaded sleeve, a threaded rod and a motor. An excrement feeding inlet is formed in the side wall of a feeding end of the thread sleeve, and a dry excrement outlet is formed in the discharging end of the thread sleeve; the threaded rod is arranged in the threaded sleeve, a spiral groove for guiding and squeezing excreta in the excrement feeding inlet and then discharging the excreta from a dry excrement discharging opening is formed in the outer side wall of the threaded rod; and the depth of the spiral groove is gradually decreased in the direction from the excrement feeding inlet to the dry excrement discharging opening; and the motoris fixedly connected with one end of the threaded sleeve, and one end of the threaded rod is in transmission connection with the motor. By means of a squeezing mechanism composed of the threaded sleeve and the threaded rod, solid-liquid separation is rapidly conducted on sewage containing excrement after a closestool or a urinal is flushed, the subsequent purification burden is relieved, the service life of a rear filtering device is prolonged, the maintenance frequency is reduced, and subsequent water resource recycling is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices used in conjunction with toilets or urinals. Background technique [0002] After the existing toilet or urinal enters the toilet, the excrement is generally washed away directly by a large amount of clear water. Although the sewage from flushing the toilet or urinal is discharged into the urban sewage pipe network after being treated in the septic tank, it pollutes the water source. Heavy. [0003] In addition, for some areas where water resources are scarce, temporary toilets, or vehicles, such as: high-speed rail and airplanes, in order to ensure flushing after using the toilet and collect sewage, relatively large clean water storage tanks and sewage storage tanks are required. The water tank occupies a large volume, which increases the carrying burden.
