Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0030] Such as Figures 1 - 7As shown in the figure, a sewage treatment tank proposed by an embodiment of the present application includes: a filtration tank 1, a water inlet pipe 2 and a drain pipe 3 are connected to the filtration tank 1, and a discharge port 4 is penetrated and opened on the outer surface of one side of the filtration tank 1; preferably, the water inlet pipe 2 penetrates and communicates with the top of the filtration tank 1, the drain pipe 3 communicates with the bottom of one side of the filtration tank 1, a ring frame 5 is arranged on the inner wall of the filtration tank 1, which has a horizontal first ring plate 501 and a vertical second ring plate 502, and a waste discharge port 503 communicating with the discharge port 4 is constructed on the first ring plate 501; an annular groove is formed between the first ring plate 501, the second ring plate 502 and the inner wall of the filtration tank 1, the waste discharge port 503 communicates with the groove, a filter screen plate 6 is arranged on the second ring plate 502; a collar 7 is rotatably sleeved on the water inlet pipe 2, and two scraping plates 8 are symmetrically arranged on the collar 7, the scraping plate 8 has a first scraping plate 801 and a second scraping plate 802, the first scraping plate 801 overlaps with the filter screen plate 6, and the second scraping plate 802 overlaps with the first ring plate 501; a hydrodynamic mechanism 9 is arranged on the water inlet pipe 2, which is used to drive the collar 7 to rotate by means of water flow. When filtering sewage in the early stage, pour the sewage into the water inlet pipe 2, the sewage will flow and impact the filter screen plate 6, the water will directly pass through the filter screen plate 6, and the filter screen plate 6 will intercept the impurities in the sewage. The hydrodynamic mechanism 9 drives the collar 7 to rotate, thereby driving the two scraping plates 8 to rotate. When the scraping plate 8 rotates, the first scraping plate 801 rotates and scrapes against the filter screen plate 6, and the second scraping plate 802 rotates and scrapes against the first ring plate 501. Under the rotation and scraping of the first scraping plate 801, the impurities intercepted on the filter screen plate 6 are scraped and dropped onto the first ring plate 501, and the second scraping plate 802 scrapes the impurities dropped onto the first ring plate 501. When the impurities are scraped by the second scraping plate 802 and move along the first ring plate 501, when passing through the waste discharge port 503, the impurities are discharged from the waste discharge port 503 and the discharge port 4. Under the overall structure of the device, when continuously filtering sewage, the intercepted impurities can be automatically removed from the filter screen plate 6 and discharged out of the filtration tank 1 through the discharge port 4, so that no impurity accumulation will occur on the filter screen plate 6, ensuring the smoothness of the filtration of the filter screen plate 6, thereby improving the filtration efficiency of the sewage.

[0031] As Figure 5 and Figure 6As shown, in some embodiments, the hydrodynamic mechanism 9 includes a bevel gear ring 901, a shaft 902, two bevel gears 903 and an impeller 904, wherein: the bevel gear ring 901 is coaxially fixed on the collar 7, the shaft 902 rotates and passes through the water inlet pipe 2, the two bevel gears 903 are respectively fixed on both ends of the shaft 902 and are meshed with the teeth of the bevel gear ring 901, the impeller 904 is fixed on the shaft 902 and is located in the water inlet pipe 2, when the water flows along the water inlet pipe 2, the water will hit the impeller 904, and under the action of the impact force, the shaft 902 is driven to rotate, and when the shaft 902 rotates, the bevel gear 903 is driven to rotate, and the teeth of the bevel gear 903 and the bevel gear ring 901 are meshed, thereby achieving the effect of driving the collar 7 to rotate.

[0032] like Figure 2 and Figure 4 As shown, in some embodiments, the filter mesh plate 6 has a conical structure with the conical tip facing upward. Preferably, the conical tip of the filter mesh plate 6 is opposite to the water inlet pipe 2. By making the filter mesh plate 6 have a conical structure, impurities can slide more smoothly from the filter mesh plate 6 to the first ring plate 501, so as to quickly remove the impurities from the filter tank 1.

[0033] like Figure 4 As shown, in some embodiments, a plurality of seepage holes 10 distributed in a circular array are arranged on the first ring plate 501. Due to the conical structure of the filter mesh plate 6, when impurities fall from the filter mesh plate 6 to the first ring plate 501, they will also carry a small amount of water. Through the opening of the seepage holes 10, a secondary filtration effect is achieved to reduce the outflow of sewage and only remove impurities.

[0034] like Figure 4 and Figure 6 As shown, in some embodiments, a baffle 11 corresponding to the impurity discharge port 503 is provided on the filter screen plate 6, and avoidance grooves 12 corresponding to the baffle 11 are constructed on the two first scrapers 801. Through the setting of the baffle 11, when impurities on the filter screen plate 6 fall, the impurities at the position corresponding to the impurity discharge port 503 will be blocked by the baffle 11, and the avoidance grooves 12 are opened, so that the baffle 11 will not cause obstruction to the scraper and brush plate 8, so that impurities need to be staggered from the position of the impurity discharge port 503 before they can fall onto the first ring plate 501, so as to reduce the phenomenon of water flowing directly out of the impurity discharge port 503.

[0035] like Figure 6As shown, in some embodiments, a number of connecting blocks 13 are arrayed on the inner wall of the second ring plate 502, and a number of insertion rods 14 are arrayed on the filter screen plate 6. The number of insertion rods 14 respectively pass through the number of connecting blocks 13 movably. A spring 15 sleeved on the insertion rods 14 is installed between the filter screen plate 6 and the connecting blocks 13. Two convex blocks 16 are symmetrically arranged on the outer surface of the filter screen plate 6. Preferably, the convex blocks 16 are in an arc structure. When the first scraping plate 801 scrapes along the filter screen plate 6, it will contact the convex blocks 16, thereby driving the filter screen plate 6 to move downward and compress the spring 15. When the first scraping plate 801 passes over the convex blocks 16, under the elastic force of the spring 15, the filter screen plate 6 moves upward to reset. With the rotation and scraping of the scraping plate 8, it will drive the filter screen plate 6 to move up and down intermittently in a reciprocating manner, so that the filter screen plate 6 has a certain vibration force. Under the action of the vibration force, the smoothness of impurities falling from the filter screen plate 6 onto the first ring plate 501 is further improved. At the same time, it also effectively avoids the blockage of the filter screen plate 6 by impurities.

[0036] As Figure 2 and Figure 3 shown, in some embodiments, a receiving box 17 corresponding to the discharge port 4 is detachably installed on the outer surface of the filter tank 1. Preferably, fixing blocks are arranged on both sides of the outer surface of the filter tank 1 and at the position of the discharge port 4. Through holes are respectively formed through the two fixing blocks. Two insertion rods are arranged on the receiving box 17, and the two insertion rods are respectively inserted and matched with the two through holes. Through the arrangement of the receiving box 17, it is used to receive the impurities discharged from the discharge port 4, so as to facilitate the subsequent cleaning of the impurities.

[0037] As Figure 5 shown, in some embodiments, a guide plate 18 is inclinedly arranged above the impeller 904 in the water inlet pipe 2. Through the arrangement of the guide plate 18, it is used to reduce the caliber of the water inlet pipe 2, improve the water pressure impact force of the water flow on the impeller 904, and at the same time, guide the water flow so that the sewage impacts the blade end of the impeller 904, further improving the smoothness of the rotation of the impeller 904.

Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
