DETAILED DESCRIPTION

[0018] The following will be further explained in detail with reference to the accompanying drawings. Figures 1-6 The present application is further explained in detail.

[0019] The present application discloses an environment-friendly sewage filtering equipment, which refers to the prior art Figure 1 , Figure 2 and Figure 3, including a circular filter cartridge 1, a water inlet 2 is formed at the top of the filter cartridge 1, a water outlet 3 is formed at the bottom of the filter cartridge 1, a filter screen 4 is installed in the filter cartridge 1, the filter screen 4 is installed between the water inlet 2 and the water outlet 3, the installation position of the filter screen 4 cannot be too close to the water inlet 2, the filter screen 4 is installed at a distance of 30-60CM from the filter port 3, in this embodiment, the installation position of the filter screen 4 is 350CM away from the water outlet 3, the filter screen 4 is slidably arranged in the filter cartridge 1 along the height direction of the filter cartridge 1, a vibration mechanism 5 is arranged between the filter screen 4 and the filter cartridge 1, the vibration mechanism 5 includes a guide ring 51, a guide rod 52 and a vibration spring 53, the guide ring 51 is fixedly arranged on the filter cartridge 1, the guide rod 52 is fixedly arranged on the filter screen 4, the guide rod 52 is slidably inserted into the guide ring 51, the vibration spring 53 is sleeved on the guide rod 52, one end of the vibration spring 53 abuts against the guide ring 51, the other end of the vibration spring 53 abuts against the filter screen 4, in this embodiment, the guide rod 52 is arranged in four positions which are uniformly distributed in the circumferential direction of the guide ring 51, and four vibration springs 53 are arranged corresponding to the filter screen 4, the filter screen 4 is driven to slide by the impact of sewage on the filter screen 4, and then the filter screen 4 is reset by the elastic force of the vibration spring 53, thereby realizing the vibration of the filter screen 4, so that the power mechanism for vibrating the filter screen 4 is not needed, and energy is saved; in order to ensure the impact force of the sewage, the installation position of the filter screen 4 cannot be too close to the water inlet 2; the vibration motor is used to drive the filter screen 4 to vibrate, and the impact force of the sewage will act on the filter screen 4, which is easy to cause damage to the filter screen 4, and when the water flow impacts, the filter screen 4 is in a lifted state, which is more likely to damage the filter screen 4 and even cause damage to the power source, and the vibration spring 53 can also alleviate the impact force of the water flow, convert the impact force into driving force, and reduce the probability of damage to the filter screen 4 caused by the impact of the sewage.

[0020] Referring to Figure 2 and Figure 3 , the filter screen 4 is arranged obliquely in the filter cartridge 1, and a receiving hopper 6 is fixedly arranged on the low side of the filter screen 4, the obliquely arranged filter screen 4 can guide the filtered sundries to accumulate on the low side of the filter screen 4, and the receiving hopper 6 can receive the sundries accumulated on the filter screen 4.

[0021] Referring to Figure 2 and Figure 3The filter cylinder 1 has a discharge port 7, and a baffle 8 is hinged to the discharge port 7. The baffle 8 opens or closes the discharge port 7 by rotation. In this embodiment, a torsion spring is installed between the baffle 8 and the filter cylinder 1. The torsion of the torsion spring drives the baffle 8 to close the discharge port 7 under normal conditions. When there is too much debris in the receiving hopper 6, the discharge port 7 can be opened by rotating the baffle 8 to discharge the debris out of the filter cylinder 1. The receiving hopper 6 has no sidewall facing the discharge port 7, so that the debris can be directly discharged from the receiving hopper 6 to the discharge port 7. A rotating rod 9 is fixed on the baffle 8, and a driving rod 10 is fixed on the receiving hopper 6. The debris in the receiving hopper 6 squeezes the vibration spring 53, causing the driving rod 10 to abut against the rotating rod 9 and drive the baffle 8 to rotate and open the discharge port. 7. When there is too much debris in the receiving hopper 6, the weight of the debris will drive the filter screen 4 to slide and compress the vibration spring 53. The sliding of the filter screen 4 will drive the receiving hopper 6 and the drive rod 10 on the receiving hopper 6. The drive rod 10 will abut against the rotating rod 9 to drive the baffle 8 to rotate and open the discharge port 7, so that the debris in the receiving hopper 6 will be discharged from the discharge port 7 into the filter cylinder 1. In this embodiment, the force required for the sliding of the filter screen 4 can be adjusted by replacing the vibration spring 53, thereby adjusting the weight of debris required for the drive rod 10 to abut against the rotating rod 9 to open. At the same time as replacing the vibration spring 53, a section of pipe can be connected at the inlet 2 to increase the initial height of the sewage entering the filter cylinder 1, thereby ensuring that the impact force of the sewage can drive the filter screen 4 to vibrate.

[0022] Reference Figure 2 An adsorption mechanism 11 is provided between the outlet 3 and the filter screen 4 in the filter cylinder 1. The adsorption mechanism 11 is used to adsorb chemical substances in the sewage. The adsorption mechanism 11 includes an adsorption cylinder 111 and an adsorbent 112. The adsorption cylinder 111 is installed inside the filter cylinder 1. Water permeable holes 21 are opened at both ends of the filter cylinder 1 along its length. The adsorbent 112 fills the filter cylinder 1. The adsorbent 112 includes an activated carbon layer 1121, a sand and gravel layer 1122, and a gravel layer 1123. The activated carbon layer 1121 is located at the bottom of the adsorption cylinder 111, and the sand and gravel layer 1122 is laid on top of the activated carbon layer inside the adsorption cylinder 111. On layer 1121, the gravel layer 1123 is laid on top of the sand and gravel layer 1122 inside the adsorption cylinder 111. When there is too much debris in the receiving hopper 6, the weight of the debris will drive the filter screen 4 to slide and compress the vibration spring 53. Both the sand and gravel layer 1122 and the gravel layer 1123 can be used to adsorb small insoluble impurities in the water. The activated carbon layer 1121 can effectively adsorb pigments, odors and some soluble impurities in the water. The adsorption mechanism 11 can adsorb fine particles that the filter screen 4 cannot filter in the sewage, and can also adsorb some chemical substances dissolved in the water, thereby improving the sewage filtration effect.

[0023] Reference Figure 2 and Figure 4The adsorption cylinder 111 is detachably installed on the filter cylinder 1, the sidewall of the filter cylinder 1 is provided with an installation hole 12, the adsorption cylinder 111 is installed on the filter cylinder 1 by sliding insertion, the installation rod 13 is fixed on the adsorption cylinder 111, the installation groove 14 is provided on the filter cylinder 1 corresponding to the installation rod 13, the installation groove 14 comprises an insertion groove 141 and an annular groove 142, the installation rod 13 is inserted into the insertion groove 141 and then rotates into the annular groove 142 through the adsorption cylinder 111, so that the installation and fixation of the adsorption cylinder 111 are completed, the detachable adsorption cylinder 111 can facilitate the replacement of the adsorbent 112 after the adsorbent 112 adsorbs too many impurities, and the installation rod 13 cooperates with the installation groove 14 to facilitate the disassembly and assembly of the adsorption cylinder 111, and also reduces the probability that the adsorption cylinder 111 is separated after installation.

[0024] Referring to Figure 1 , Figure 4 , Figure 5 and Figure 6, the filter cartridge 1 is provided with a plurality of partition plates 15 on the side of the filter screen 4 facing the water inlet 2. In this embodiment, five partition plates 15 are provided, which can open or close the water inlet 2 by rotating. The partition plates 15 can be closed by rotating the water inlet 2, thereby reducing the probability of sewage passing through when replacing the adsorption mechanism 11, thereby reducing the probability of sewage leaking or directly leaving the filter cartridge 1 without being filtered; the filter cartridge 1 is provided with a rotating ring 16, which is rotatably arranged on the filter cartridge 1. The rotating ring 16 is provided with a driving groove 17 corresponding to the partition plate 15, and the partition plate 15 is provided with a driving rod 18. The rotating ring 16 connects all partition plates 15 through the driving groove 17 and the driving rod 18, and the rotation of the rotating ring 16 can drive all partition plates 15 to rotate synchronously, so that the partition plates 15 rotate synchronously to open or close the water inlet 2. The rotating ring 16 can conveniently drive all partition plates 15 to rotate synchronously, thereby conveniently controlling the opening and closing of the water inlet 2; the rotating ring 16 is fixedly provided with a linkage rod 19, which includes a driving part 191 and a connecting part 192. The driving part 191 is slidably arranged in the annular groove 142, and the connecting part 192 connects the driving part 191 and the rotating ring 16. A return spring 20 is arranged between the driving part 191 and the bottom of the annular groove 142. The elastic force of the return spring 20 drives the driving part 191 to slide away from the bottom of the annular groove 142. When the mounting rod 13 enters the annular groove 142, the mounting rod 13 slides in the annular groove 142 to drive the driving part 191 to slide synchronously until the return spring 20 is compressed to the elastic force equal to the force required for the adsorption cylinder 111 to rotate. At this time, the rotating ring 16 drives all partition plates 15 to open the water inlet 2. When the adsorption cylinder 111 is rotated to separate the mounting rod 13 from the annular groove 142, the driving part 191 slides away from the bottom of the annular groove 142 under the action of the elastic force of the return spring 20. At this time, the rotating ring 16 drives all partition plates 15 to rotate and close the water inlet 2. The linkage rod 19 and the return spring 20 can drive the partition plates 15 to open the water inlet 2 synchronously when the adsorption cylinder 111 is installed and used normally, and can also make the partition plates 15 close the water inlet 2 synchronously when the adsorption cylinder 111 is disassembled.
