Technical Field

[0001] The utility model relates to the technical field of sewage filtration, in particular to an environment-friendly sewage solid filtration device which is convenient for discharging. Background Technique

[0002] Sewage is a kind of water resource polluted in production and life.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: Please refer to Figures 1-4 , an environmentally friendly sewage solid filtration device that is convenient for discharging, including an outer shell 1. A filter cylinder 8 is installed inside the outer shell 1. A filter screen 16 is installed inside the filter cylinder 8. A rotating shaft 18 is penetrated through the inside of the filter screen 16. And a second servo motor 15 is installed on one side of the rotating shaft 18. Cleaning rods 17 are fixed at both ends of the rotating shaft 18. A discharge pipe 12 is arranged at the bottom end of the filter screen 16. And control valves 13 are arranged inside the discharge pipe 12. A storage seat 9 is installed at the bottom end of the outer shell 1. An inner cavity 11 is arranged inside the storage seat 9. And a storage box 10 is installed inside the inner cavity 11. A water outlet pipe 14 is installed on one side of the outer shell 1. A delivery pipe 6 is installed on the other side of the outer shell 1. A water inlet pipe 2 is installed at the top end of the delivery pipe 6. Four groups of filter screens 16 are provided and are circularly designed. The four groups of filter screens 16 are equally spaced inside the filter cylinder 8. The cross-section of the storage box 10 matches the cross-section of the storage seat 9. A snap-fit structure is formed between the storage box 10 and the storage seat 9. The design of the snap-fit structure makes the storage box 10 convenient for disassembly and cleaning. Two groups of cleaning rods 17 are provided. The two groups of cleaning rods 17 are symmetrically distributed about the central axis of the filter screen 16. The symmetrically distributed cleaning rods 17 have a better cleaning effect on the filter screen 16 and extend the service life of the cleaning rods 17;

[0023] Specifically, as Figure 1 , Figure 2 and Figure 3As shown, after the sewage is filtered, the control valve 13 is opened, and the second servo motor 15 is started to drive the rotation of the rotating shaft 18. The rotating shaft 18 drives the cleaning rod 17 to scrape and clean on the surface of the filter screen 16, so that the solid matter filtered out on the surface of the filter screen 16 is swept off and then falls into the interior of the storage box 10 through the discharge pipe 12 for collection.

[0024] Embodiment 2: A first servo motor 5 is installed on one side of the conveying pipe 6. A auger 21 is installed on one side of the first servo motor 5. And a scraper 7 is fixed on the outer side wall of the auger 21. There are two groups of scrapers 7. The outer side walls of the two groups of scrapers 7 are closely attached to the inner side wall of the conveying pipe 6, which has a better cleaning effect on the conveying pipe 6.

[0025] Specifically, as Figure 1 and Figure 4 shown, the first servo motor 5 is started to drive the rotation of the auger 21, and the sewage containing solid matter is evenly conveyed into the interior of the housing 1. At the same time of conveying, the scraper 7 on the outer side wall of the auger 21 also rotates together to prevent the adhesion of pollutants to the outer side wall of the conveying pipe 6.

[0026] Embodiment 3: A cooling pipe 20 is evenly wound around the outer side wall of the water inlet pipe 2. One end of the cooling pipe 20 is provided with a hot water outlet pipe 19. And a water pump 3 is installed at one end of the hot water outlet pipe 19. The other end of the cooling pipe 20 is provided with a cold water inlet pipe 4.

[0027] Specifically, as Figure 1 and Figure 3 shown, external cold water is introduced into the interior of the cooling pipe 20 through an external power device and the cold water inlet pipe 4. The cooling pipe 20 cools the pipeline, thereby cooling the sewage passing through the water inlet pipe 2. At the same time, the water pump 3 is started to pump out the hot water that has become hot inside the cooling pipe 20, and a cycle of the cold water inside the water inlet pipe 2 is carried out to enable it to better cool the sewage.

[0028] Working principle: When the utility model is in use, sewage enters the inside of the conveying pipe 6 through the water inlet pipe 2. The first servo motor 5 is started to drive the auger 21 to rotate. The auger 21 evenly conveys the sewage containing solid substances into the filter cylinder 8 inside the housing 1. The filter screen 16 inside the filter cylinder 8 filters the solid substances of the sewage and discharges them through the water outlet pipe 14 on one side. After the sewage is filtered, the second servo motor 15 is started to drive the rotating shaft 18 to rotate. The rotating shaft 18 drives the cleaning rod 17 to scrape and clean on the surface of the filter screen 16, so that the solid substances filtered out on the surface of the filter screen 16 fall through the discharge pipe 12 into the inside of the storage box 10 and are collected. Then, the rotating shaft 18 is pulled out to clean out the solid substances. When encountering high-temperature sewage, external cold water can be introduced into the inside of the cooling pipe 20 through an external power device and the cold water inlet pipe 4. The cooling pipe 20 cools the pipeline, thereby cooling the sewage passing through the water inlet pipe 2, and then the sewage enters the inside of the housing 1 for filtering work after being cooled.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
