[0034] like Figures 1 to 4As shown, this embodiment proposes a separator for a leachate disposal system, including a tank body 1, which is provided with a liquid inlet 11 and a sewage outlet 12 at the bottom of the tank body 1; the tank body 1 is also provided with a grid 2, a partition 3, and a blade assembly 4, the grid 2 can filter the filtrate flowing into the liquid inlet 11, the partition 3 is arranged below the grid 2, the partition 3 can be used to receive the leachate filtered by the grid 2, the blade assembly 4 is arranged between the grid 2 and the partition 3, the blade assembly 4 can be used to stir and cut the leachate filtered by the grid 2, and in addition, a through hole 31 is opened on the partition 3, and the through hole 31 allows the leachate to flow to the bottom of the tank body 1. In this way, through the grid 2 in the tank body 1, the large-particle impurities in the leachate can be transferred to the grid 2, thereby preventing the large-particle impurities from subsequently clogging the sewage outlet 12, saving the cost of manual cleaning; by setting the partition 3 and the blade assembly 4, and placing the partition 3 below the grid 2, the partition 3 receives the leachate filtered through the grid 2, and cooperates with the blade assembly 4 to stir and cut the leachate through the blade assembly 4, cutting the large-particle impurities (such as sludge blocks, etc.) in the leachate into fine particles, further preventing the large-particle impurities from subsequently clogging the sewage outlet 12; thereby, the through holes 31 of the partition 3 allow the small-particle impurities to seep out and fall into the bottom of the tank body 1, and finally be discharged through the sewage outlet 12. Through the multi-layer filtration treatment of the present application, it is effectively avoided that the impurities in the leachate clog the sewage outlet and affect the sewage discharge effect, the operation is convenient, and labor is saved.

[0035] In this application, the filtering principle of the separator is as follows:

[0036] First, the leachate flows into the tank body 1 through the liquid inlet 11 of the tank body 1, and is filtered through the grid 2 in advance, filtering the large particles of impurities in the leachate onto the grid 1 to achieve the first filtration; then, the leachate is stirred and cut by the blade assembly 4 to cut it into fine particles, such as cutting sludge blocks or other garbage blocks into fine particles to prevent larger particles of impurities from clogging the sewage outlet; finally, the fine-particle impurities seep out through the through hole 1 on the partition 3, effectively preventing impurities from clogging the sewage outlet.

[0037] Preferably, the particle size of the through hole 31 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc. By controlling the particle size of the through hole 31, on the one hand, the flow rate of the leachate flowing to the bottom of the tank body 1 can be controlled. On the other hand, the appropriate particle size can be selected according to actual conditions to control impurities of different sizes to flow to the bottom of the tank body 1 through the partition 3.

[0038] Further, see Figure 1As shown, the blade assembly 4 comprises a support 41, a telescopic rod 42, and a connecting base 43. The support 41 is mounted on the tank body 1, the telescopic rod 42 is mounted on the support 41, and the connecting base 43 is mounted on the telescopic rod 42. Furthermore, the connecting base 43 is equipped with a rotary motor 44. The movable end of the rotary motor 44 is equipped with a rotating shaft 45. The rotating shaft 45 is equipped with a blade 46. The blade 46 is configured to stir the leachate. The blade 46 is positioned between the grid 2 and the partition 3. Thus, the telescopic rod 42 extends and retracts to drive the connecting base 43 upward and downward, which in turn drives the rotating motor 44 upward and downward. The rotating motor 44, via the rotating shaft 45, drives the blade 46 up and down, thereby adjusting the position of the blade 46 within the tank body 1. The height of the blade 46 can be adjusted accordingly, and the rotation of the blade 46 by the rotating motor 44 ensures that impurities in the leachate are fully stirred and cut, effectively ensuring the stirring and cutting efficiency.

[0039] Preferably, in the application, the telescopic rod 42 is connected to the connecting base 43 via a connecting plate 48. The provision of the connecting plate 48 increases the distance between the connecting base 43 and the telescopic rod 42, preventing interference between the various components during the lifting process. Preferably, the telescopic rod 42 and the connecting plate 48 are integrally formed, which reduces subsequent machining and production costs.

[0040] Further, see Figure 3 As shown, the grid 2 is provided with a stopper 5, which defines a passage 51. Through the passage 51, one end of the rotating shaft 45 can pass through and connect with the blade 46. By providing the stopper 5, the movement direction of the rotating shaft 45 can be limited, allowing the rotating shaft 45 to move in its designated direction.

[0041] Preferably, see Figure 4 As shown, the blade 46 is provided with a filter hole 47 coated with a deodorant. The deodorant can be used to remove the odor of the leachate. Alternatively, an active agent can be applied to the filter hole 47 to activate the leachate and decompose the pollutants therein. Depending on actual conditions and specific needs, the filter hole 47 can also be coated with other treatment agents, which are not intended to be exclusive here.

[0042] Preferably, a driving cylinder (not shown in the drawings) is provided on the support 41. By driving the cylinder, the telescopic rod 42 can be driven to extend and retract, thereby realizing automated processing. Of course, in the present application, the telescopic rod 42 can also be adjusted manually, which is not the only limitation here.

[0043] Preferably, see Figure 4As shown, the partition plate 3 is arranged in an inverted cone shape. By arranging the inverted cone shape, it is convenient to receive the leachate, and provides a guarantee for the blade assembly 4 to perform better stirring and cutting.

[0044] Further, see Figure 2 As shown, the tank 1 comprises a housing 13, a sealing cover 14, and support legs 15. The sealing cover 14 is mounted on the top of the housing 13, and the support legs 15 are installed on the bottom of the housing 13. Thus, the support legs 15 support the housing 13, facilitating the discharge of sewage through the sewage outlet 12. The sealing cover 14 also seals the housing 1, preventing the leachate from emitting odor during the separation process.

[0045] Preferably, the number of the supporting legs 15 is three, and the angle between two adjacent supporting legs 15 is 120°. Through the triangular distribution, effective support for the tank body 1 is achieved. Of course, in this application, the number of the supporting legs 15 can also be set to four or other multiples, and this is not a sole limitation.

[0046] Further, see Figure 3 As shown, an observation window 6 is provided on the housing 13 at a position corresponding to the grid 2. In this way, the filtering condition of the grid 2 can be observed through the observation window 6, so as to judge whether the grid 2 needs to be cleaned, which is simple and efficient.

[0047] Preferably, see Figure 2 As shown, the sealing cover 6 is provided with a lifting ring 7. By providing the lifting ring 7, when the entire separator needs to be moved, the entire separator can be lifted and moved by hooking the lifting ring 7 with a crane, which is fast and convenient and meets the various needs of users.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
