Description

Technical Field

[0001] The invention relates to the technical field of filtering and separating devices, in particular to a sludge environmentally friendly filtering and separating device. Background Art

[0002] Sludge is the product of sewage treatment. It is an extremely complex inhomogeneous body composed of organic debris, bacterial cells, inorganic particles and colloids. The main characteristics of sludge are high water content (up to more than 99%), high organic content, easy to decompose and stink, fine particles, low specific gravity, and a colloidal liquid state. It is a thick substance between liquid and solid and can be transported by pumps, but it is difficult to separate solids and liquids by sedimentation.

[0003] The existing sludge environmental protection filtering and separation device has a publication number of CN208603987U on the patent website. It only uses centrifugal force to grade and separate the sludge to ensure that the water in the sludge can be completely separated. Through the cooperation of the filter screen and the permeation hole, the water and the sludge can be separated from different directions and the sludge separation effect can be improved. The existing sludge environmental protection filtering and separation device has a slow separation speed when separating the sludge and water, resulting in low work efficiency. When separating the sludge and water, the separation is not thorough enough. The separated sludge needs to be crushed by other equipment in the later stage, resulting in low economic benefits.

[0015] (III) Beneficial effects

[0016] The present invention provides a sludge environmentally friendly filtering and separation device, which has the following beneficial effects:

[0017] (1) This kind of sludge environmentally friendly filtering and separating device is provided with a vibration motor, a mud-water separation filter layer and a leaking filter layer. When the device is running, the sludge added from the feed hopper will enter the separation box. When the sludge falls into the mud-water separation filter layer in the separation box, the vibration motor will vibrate, and the vibration motor will drive the mud-water separation filter layer to vibrate. The sludge will vibrate due to the vibration of the vibration motor, and the sludge and water will be separated. The water will pass through the mud-water separation filter layer due to gravity. At this time, the driving motor drives the mud transport mechanism to bring the sludge into the separation body. When a small amount of water in the sludge passes through the leaking filter layer, it will flow into the lower water tank through the leaking filter layer. In this way, two different mud-water separation methods are used, thereby improving the working efficiency of the device.

[0018] (2) This sludge environmentally friendly filtering and separating device is provided with a hydraulic cylinder, an extrusion plate and a sludge filter layer. When the sludge enters the dewatering barrel through the discharge pipe, the hydraulic cylinder drives the extrusion plate and the sludge filter layer on the extrusion shaft to move forward, and the discharge pipe will be closed by the sealing plate, and the sludge will be pushed up. The pushed sludge will be slowly compressed. The water that is not completely separated in the sludge will pass through the sludge filter layer and flow out from the water outlet on the extrusion plate due to the effect of pressure. In this way, the sludge and water can be separated more thoroughly.

[0019] (3) This type of sludge environmentally friendly filtering and separation device has a disc that is set up. When the sludge is squeezed to a certain extent, the disc will form a gap with a part of the dewatering barrel due to the squeezing force of the hydraulic cylinder. At this time, the sludge will be slowly squeezed out through the gap, and the squeezed sludge will be in the form of small pieces of sludge. In this way, the separated sludge does not need to be crushed by other equipment in the later stage, thereby improving the economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
