[0035] Reference below Figure 1-Figure 5 The invention describes a landfill leachate treatment device according to an embodiment of the invention.

[0036] like Figure 1-Figure 5 As shown, the garbage leachate treatment equipment includes a reaction chamber 100, a filter disc 200 and a rotating disc changing mechanism.

[0037] Specifically, the reaction chamber 100 is provided with a steam pipe 110 and a drain pipe 120. The reaction chamber 100 adopts an upper and lower layer structure, the top is connected to the steam pipe 110, the bottom is connected to the drain pipe 120, and the middle part of the reaction chamber 100 is hollowed out. The upper layer of the reaction chamber 100 is also provided with a spare pipe, and different components are installed or connected to different devices according to actual use requirements. The filter disc 200 is detachably arranged at the middle hollow part of the reaction chamber 100. When the filter disc 200 is located at the hollow part of the reaction chamber 100, the upper and lower layers of the reaction chamber 100 are sealed and connected to the top and bottom of the filter disc 200 respectively. At this time, the high-temperature gas introduced into the reaction chamber 100 by the steam pipe 110 fully reacts with the garbage on the filter disc 200, so that the garbage leachate is precipitated and falls into the lower layer of the reaction chamber 100. When the amount of leachate stored in the lower layer of the reaction chamber 100 reaches a certain amount, it is discharged into the liquid storage mechanism through the drain pipe 120 and transferred to the next process.

[0038] The rotating disc changing mechanism is arranged on one side of the reaction chamber 100, and includes a driving component 310 and a rotating component 320. The two ends of the rotating component 320 are respectively connected to the two filter discs 200. The driving component 310 drives the rotating component 320 to drive the two filter discs 200 to switch positions in the reaction chamber 100. Specifically, in this embodiment, the rotating component 320 can drive the two filter discs 200 to rotate at the same time. When one of the filter discs 200 is in the reaction chamber 100, the other filter disc 200 is located outside the reaction chamber 100. The staff can process the filter residue in the filter disc 200 without stopping the processing equipment. The equipment can work continuously and uninterruptedly without stopping the equipment to wait, which greatly improves the working efficiency of the equipment.

[0039] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the rotating assembly 320 includes a rotating shaft 322 and a transposition base 321, the output shaft of the driving assembly 310 protrudes from the middle of the transposition base 321 and is connected to the middle of the rotating shaft 322, and both ends of the rotating shaft 322 are fixedly connected to the filter disc 200 through couplings 327.

[0040] Specifically, the driving assembly 310 is disposed directly below the transposition base 321, and the output shaft vertically extends to the middle of the transposition base 321 and is connected to the rotating shaft 322. The two ends of the rotating shaft 322 are respectively provided with filter discs 200.

[0041] In a further embodiment, Figure 3 As shown, a vertical guide bevel gear 323 is provided on one side of the rotating shaft 322 close to the filter disc 200 , the vertical guide bevel gear 323 is sleeved with the rotating shaft 322 , and the distance from the vertical guide bevel gear 323 to the transposition base 321 is not greater than the radius of the transposition base 321 .

[0042] A guide rack 324 meshing with the vertical guide bevel gear 323 is provided on the periphery of the transposition base 321 . When the filter disc 200 rotates to the position of the guide rack 324 , the vertical guide bevel gear 323 meshes with the guide rack 324 to adjust the vertical position of the filter disc 200 .

[0043] Specifically, the weights of the filter discs 200 on both sides of the rotating shaft 322 are inconsistent after processing, so in order to accurately insert the filter disc 200 into the cavity of the reaction chamber 100, the vertical guide bevel gear 323 is engaged with the guide rack 324, and the position of the filter disc 200 on the corresponding side is calibrated to ensure that it is at a specified height, and then accurately inserted into the middle hollow of the reaction chamber 100.

[0044] In some embodiments of the present invention, Figure 3 As shown, the rotating shaft 322 is provided with an L-shaped balancing rod 325 and a spring 326. One end of the L-shaped balancing rod 325 is connected to the coupling 327, and the other end passes through the rotating shaft 322 and is sleeved with the spring 326. One end of the spring 326 abuts against the rotating shaft 322, and the other end abuts against the end of the L-shaped balancing rod 325.

[0045] Specifically, the filter disc 200 is connected to the filter disc 200 via a coupling 327 . When the vertical guide bevel gear 323 engages with the guide rack 324 , the spring 326 assists the filter disc 200 in adjusting its position through elastic deformation, thereby avoiding wear caused by hard engagement of the vertical guide bevel gear 323 with the guide rack 324 .

[0046] In a further embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the end of the L-shaped balance bar 325 and the spring 326 is spherical. The spherical end is convenient for reducing the contact friction between the end and the transposition base 321.

[0047] In a further embodiment, Figure 3 As shown, a balance platform 328 is provided at a position of the transposition base 321 corresponding to the active track of the L-shaped balance bar 325, and a guide slope 328-1 is provided at one end of the balance platform 328. The spherical end of the L-shaped balance bar 325 slides along the guide slope 328-1 toward the balance platform 328. Specifically, the balance platform 328 is laid on the transposition base 321 along the active track of the spherical end. After the spherical end contacts the guide slope 328-1, it slides toward the end surface of the balance platform 328, assisting the vertical guide bevel gear 323 to calibrate the position of the filter disc 200.

[0048] In some embodiments of the present invention, Figure 5As shown, the filter disc 200 is provided with a detachably connected filter bucket 210, which is installed in the filter disc 200 and enters the reaction chamber 100 along with the filter disc 200. Specifically, the middle part of the filter bucket 210 is a mesh structure, which is provided with a plurality of mesh holes, and the leachate falls into the lower half of the reaction chamber 100 through the mesh holes, and is finally discharged through the drain pipe 120.

[0049] In a further embodiment, Figure 5 As shown, the filter plate 200 is provided with an elastic support member 220, which is arranged around the periphery of the filter plate 200, and the periphery of the filter bucket 210 abuts against the elastic support member 220. Specifically, the elastic support member 220 can adjust the position of the filter bucket 210 according to the weight of the filter bucket 210. When the filter bucket 210 reacts to form filter residue, the weight of the filter bucket 210 decreases, and at this time, the elastic potential energy of the elastic support member 220 is converted into mechanical energy to push the filter bucket 210 up.

[0050] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the upper layer and the lower layer of the reaction chamber 100 adopt a double-layer shell structure, and the upper layer and the lower layer of the reaction chamber 100 are connected by a structural plate 130 .

[0051] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, a control valve 140 is provided between the drain pipe 120 and the reaction chamber 100 .
