Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-3 , the present invention provides a technical solution: a solid-liquid separation mechanism for sewage treatment, including a filtration box 1; a filtration cylinder 2 is inclined and rotatably installed in the filtration box 1; a feed hopper 3 is arranged on the side wall of the filtration box 1 and extends into the filtration cylinder 2; a drive assembly 4 is arranged on the filtration box 1 for driving the filtration cylinder 2 to rotate; a cleaning assembly 5 is arranged in the filtration cylinder 2 for cleaning the inner wall of the filtration cylinder 2; an extrusion assembly 6 is arranged at the discharge end of the filtration cylinder 2 for secondarily extruding the filtered impurities; a collection port 7 is arranged on the side wall of the filtration box 1 and is located below the extrusion assembly 6; a collection box 8 is arranged at the discharge end of the extrusion assembly 6. The sewage is filtered by the rotating filtration cylinder 2, and the filtration cylinder 2 is cleaned by the cleaning assembly 5, realizing that the filtration separation device can continuously separate the solid and liquid in the sewage, avoiding the need for manual intermittent cleaning of the solid debris on the surface of the filter screen that plays a filtering role. At the same time, for the solid residues in the sewage, they are extruded and dehydrated by the extrusion assembly 6, ensuring the sewage treatment effect.

[0025] Specifically, the drive assembly 4 includes a drive motor 4-1 arranged on the filtration box 1. A first gear 4-2 is provided at the drive end of the drive motor 4-1. An external gear ring 4-3 meshingly connected with the first gear 4-2 is provided on the side wall of the filtration cylinder 2. During use, by starting the drive motor 4-1 to drive the first gear 4-2 to rotate, the first gear 4-2 drives the external gear ring 4-3 and the filtration cylinder 2 to rotate, realizing that the drive assembly 4 drives the filtration cylinder 2 to rotate.

[0026] Specifically, the cleaning component 5 includes fixing plates 5-1 arranged at both ends of the filter tank 1. A rotating rod 5-2 is arranged between the two fixing plates 5-1. A scraping plate 5-3 is arranged on the side wall of the rotating rod 5-2. An internal gear ring 5-4 is arranged on the inner wall of the end of the filter cylinder 2. A second gear 5-5 meshed with the internal gear ring 5-4 is arranged on the side wall of the rotating rod 5-2. During use, when the filter cylinder 2 rotates, it drives the internal gear ring 5-4 to rotate. The internal gear ring 5-4 drives the second gear 5-5, the rotating rod 5-2 and the scraping plate 5-3 to rotate, realizing the cleaning of the inner wall of the filter cylinder 2, enabling the filter separation device to continuously carry out solid-liquid separation of sewage, and avoiding the need for manual intermittent cleaning of the solid debris on the surface of the filter screen that plays a filtering role.

[0027] Specifically, the extrusion component 6 includes two conveyor belt components 6-1 arranged oppositely at the discharge end of the filter cylinder 2. The conveyor belt component 6-1 located below is longer than the conveyor belt component 6-1 located above. A number of evenly distributed extrusion rollers 6-2 are arranged inside the conveyor belt component 6-1. The conveyor belt component 6-1 located below is fixedly arranged above the collection port 7. An electric cylinder 6-3 is arranged on the filter tank 1. An installation seat 6-4 is arranged at the output end of the electric cylinder 6-3. The conveyor belt component 6-1 located above is installed on the installation seat 6-4. During use, by starting the electric cylinder 6-3, it drives the installation seat 6-4 and the conveyor belt component 6-1 located above to move up and down, controlling the pressure between the two conveyor belt components 6-4. After the solid residues in the sewage pass through the filter and fall onto the conveyor belt component 6-1 located below, they are conveyed by the conveyor belt component 6-1 located below and enter between the two conveyor belt components 6-1 for extrusion. The sewage after extrusion of the solid residues falls into the collection port 7 and then returns to the inside of the filter tank 1. The solid residues after extrusion enter the inside of the collection box 8 for collection. Through the extrusion dehydration treatment by the extrusion component 6, the treatment effect of the sewage is ensured.

[0028] Specifically, a number of guide rods 6-5 penetrate through the installation seat 6-4. The number of guide rods 6-5 is divided into two groups, which are respectively located at the front and rear ends of the installation seat 6-4. A connecting seat 6-6 for installing the extrusion roller 6-2 is arranged at the bottom of the guide rod 6-5. A spring 6-7 is arranged outside the guide rod 6-5 and between the installation seat 6-4 and the connecting seat 6-6. When there are relatively large impurities in the solid residues, the extrusion roller 6-2 drives the guide rod 6-5 to move upward under force, compressing the spring 6-7, effectively avoiding the problem that relatively large impurities in the sewage cannot pass through the two conveyor belt components 6-1, and ensuring the stability of the operation of the extrusion component 6.

[0029] Working principle: During the use of the utility model, the driving component 4 is first started to drive the filter cylinder 2 to rotate. After adding sewage into the filter cylinder 2 for filtration, the cleaning component 5 is driven to clean the inner wall of the filter cylinder 2 during the rotation of the filter cylinder 2. The solid residues filtered out are extruded by the extrusion component 6, and the sewage extruded out returns to the inside of the filter tank 1 through the collection port 7. The solid residues after extrusion enter the collection box 8 for collection, thus improving the sewage treatment effect.
