[0038] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0039] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0040] Please combine Figures 1 to 6 The ferromagnetic impurity recovery device provided by the present invention is now described. The ferromagnetic impurity recovery device is applied to sewage treatment equipment.

[0041] The ferromagnetic impurity recovery device includes a shell 1, a driving motor 2, a transmission component 3, a filter 4, an adsorbent 7 and a collecting component 8. The shell 1 is provided with an opening 11 and a accommodating space 12 connected to the opening 11. The filter 4 and the adsorbent 7 are both placed in the accommodating space 12, and the filter 4 and the adsorbent 7 are both rotatably connected to the wall of the accommodating space 12. The driving motor 2 is connected to the transmission component 3, and the transmission component 3 is transmission-connected to the filter 4 and to the adsorbent 7. The driving motor 2 drives the transmission component 3 to drive the filter 4 and the adsorbent 7 to rotate. The collecting component 8 is installed on the shell 1 and is used to collect ferromagnetic impurities on the adsorbent 7.

[0042] In the process of liquid flowing from the opening 11 to the accommodating space 12, the driving motor 2 can drive the transmission component 3 to drive the filter 4 to rotate, and the adsorption component 7 is stationary. The driving motor 2 can also drive the transmission component 3 to drive the adsorption component 7 to rotate, and the filter 4 is stationary. The filter 4 can recover the ferromagnetic impurities in the liquid on the surface of the filter 4, and the adsorption component 7 can adsorb the ferromagnetic impurities remaining on the surface of the filter 4.

[0043] It can be understood that when the liquid flows in the accommodating space 12, in order to recover the ferromagnetic impurities in the sewage, the driving motor 2 drives the transmission component 3 to drive the filter element 4 to rotate, and the adsorption component 7 is stationary. The driving motor 2 can also drive the transmission component 3 to drive the adsorption component 7 to rotate, and the filter element 4 is stationary. The filter element 4 can recover the ferromagnetic impurities in the liquid on the surface of the filter element 4, and the adsorption component 7 can absorb the ferromagnetic impurities remaining on the surface of the filter element 4 through magnetic force, so that when the ferromagnetic impurities are recovered, the ferromagnetic impurities can be recovered in stages and regions, which can greatly reduce the residual ferromagnetic impurities and improve the recovery efficiency.

[0044] In this embodiment, the transmission assembly 3 includes an active dial 31, two driven sheaves 32 and two mounting shafts 33. The active dial 31 is connected to the output shaft of the driving motor 2. Each mounting shaft 33 is rotatably connected to the housing 1. Each driven sheave 32 is connected to each mounting shaft 33 in a one-to-one correspondence. The active dial 31 is arranged between the two driven sheaves 32. The driven sheaves 32 have radial grooves 36 and concave locking arcs 37. A circular protrusion 34 is provided in the middle of the active dial 31. When the round pin 35 on the active dial 31 enters the radial groove 36 of the driven sheave 32, the corresponding driven sheave 32 is driven by the round pin 35 to rotate, and the circular protrusion 34 cooperates with the concave locking arc 37. The two driven sheaves 32 are respectively connected to the filter element 4 and the adsorbent 7. The active dial 31 always rotates in one direction driven by the drive motor 2. When the round pin 35 of the active dial 31 enters the radial groove 36 of the driven sheave 32 connected to the filter element 4, the driven sheave 32 rotates an angle driven by the round pin 35 and then remains stationary. The round pin 35 continues to rotate into the radial groove 36 of the driven sheave 32 connected to the adsorbent 7, driving the driven sheave 32 to rotate an angle and then stop. The two driven sheaves 32 have the same rotation angle and opposite directions, thereby realizing intermittent recovery in stages and regions.

[0045] Furthermore, the filter element 4 is connected to the corresponding mounting shaft 33, and the surface of the filter element 4 is provided with a filter hole 41 and an inner cavity 42 connected to the filter hole 41. When the ferromagnetic impurities in the sewage flow through the filter element 4, the ferromagnetic impurities stay on the surface of the filter element 4, which is convenient for adsorption by the adsorption element 7, and also facilitates the circulation of water.

[0046] Further, the radial projection shape of the outer surface of the filter element 4 is a polygon. Specifically, the filter element 4 of this embodiment is set to be a hexagon. The adsorbent 7 is connected to the corresponding installation shaft 33, and the shape of the adsorbent 7 is consistent with the number of faces and length of the filter element 4. Make each face of the filter element 4 correspond to each face of the adsorbent 7.

[0047] In one embodiment, the ferromagnetic impurity recovery device further includes a conveying channel 5, which includes a first conveying portion 51 and a second conveying portion 52 connected to the first conveying portion 51. The first conveying portion 51 is arranged in the inner cavity 42, and the second conveying portion 52 is arranged outside the filter element 4. Sewage flows in through the filter element 4, then flows into the first conveying portion 51, then passes through the second conveying portion 52, and is finally conveyed to a corresponding position. The conveying channel 5 is used to collect the filtered sewage.

[0048] Furthermore, the cross section of the first conveying portion 51 is semicircular and the cross section width is close to the inner diameter of the filter element 4, which reduces the splashing of the filtered liquid and makes the filtering efficiency higher. The width of the second conveying portion 52 is smaller than the first conveying portion 51. Under the same flow rate, the narrower conveying portion can increase the flow rate of the liquid, quickly transport the filtered liquid to the corresponding position, and make the sewage recovery efficiency higher.

[0049] In one embodiment, the housing 1 further includes a cavity 13, which is connected to the lower part of the accommodating space 12, and the ferromagnetic impurity recovery device further includes a filter plate 6, which is arranged between the cavity 13 and the accommodating space 12. The filter plate 6 is used to filter the sewage splashed from the water inlet pipe 9 to the conveying channel 5 to ensure the cleanliness of the liquid during the transmission process.

[0050] Furthermore, the shell 1 on both sides of the cavity 13 has a slope, so that the liquid can flow into the cavity 13 better.

[0051] Furthermore, equipment maintenance channels 16 are provided on both sides of the housing 1 for replacing recovery plates and other parts that need to be repaired, and for cleaning some impurities.

[0052] In one embodiment, the ferromagnetic impurity recovery further includes a water inlet pipe 9, a water pump 91 and a pipe 92. The water pump 91 is arranged in the cavity 13 and is connected to the pipe 92. The pipe 92 is exposed from the cavity 13 to the outside of the housing 1 and is connected to the lower end of the water inlet pipe 9. The splashed sewage is filtered by the filter plate 6, first pumped by the water pump 91, then transported through the pipe 92, and finally flows into the accommodating space 12. The recovery efficiency of sewage is improved.

[0053] In one embodiment, the water inlet pipe 9 is arranged above the filter element 4, so that the sewage flows through the filter element 4 under the action of gravity without the need for external force.

[0054] In one embodiment, the ferromagnetic impurity recovery device further includes a collection assembly 8, which includes a scraper 81, a first elastic member 82, a baffle 83 and a second elastic member 84. The housing 1 is further provided with a first fixed plate 14 and two second fixed plates 15. The scraper 81 is provided with a first sliding groove 85. The first fixed plate 14 is arranged in the first sliding groove 85. The first elastic member 82 is elastically connected to the first fixed plate 14 and the groove wall of the first sliding groove 85. A second sliding groove 86 is formed between the two second fixed plates 15. The baffle 83 is arranged in the second sliding groove 86. The second elastic member 84 is elastically connected between the baffle 83 and the groove wall of the second sliding groove 86. Specifically, the first elastic member 82 can be a spring, and the second elastic member 84 can be a spring. The first sliding groove 85 plays a guiding role, and the first elastic member 82 moves in the first sliding groove 85. The elastic force of the first elastic member 82 changes continuously as the adsorbent 7 rotates, so that the scraper 81 always keeps in contact with the adsorbent 7, which facilitates the scraper 81 to scrape off the ferromagnetic impurities. The second sliding groove 86 plays a guiding role. The second elastic member 84 moves in the second sliding groove 86. The elastic force of the second elastic member 84 changes continuously as the adsorption member 7 rotates, so that the baffle 83 always keeps in contact with the adsorption member 7 to prevent unfiltered sewage from splashing to the side of the adsorption member 7.

[0055] The present invention also provides a sewage treatment device, which includes the ferromagnetic impurity recovery device of any one of the above embodiments.

[0056] It can be understood that the sewage treatment equipment of the present invention uses the above-mentioned magnetic impurity recovery device, so that when the liquid flows in the accommodating space 12, in order to recover the ferromagnetic impurities in the sewage, the driving motor 2 drives the transmission component 3 to drive the filter element 4 to rotate, and the adsorption component 7 is stationary. The driving motor 2 can also drive the transmission component 3 to drive the adsorption component 7 to rotate, and the filter element 4 is stationary. The filter element 4 can recover the ferromagnetic impurities in the liquid on the surface of the filter element 4, and the adsorption component 7 can use magnetic force to adsorb the ferromagnetic impurities remaining on the surface of the filter element 4, so that when the ferromagnetic impurities are recovered, the ferromagnetic impurities can be recovered in stages and regions, which can greatly reduce the residual ferromagnetic impurities and improve the recovery efficiency.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
