[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A filter press waste recovery device comprises a collection box 1, a collecting bucket 11 is fixed on the top of the collection box 1, waste discharged from the filter press is received by the collecting bucket 11, and the waste enters the collection box 1, and a support leg 12 is fixed at the bottom of the collection box 1, and the support leg 12 supports the collection box 1 as a whole.

[0028] In this embodiment, Figure 1 , Figure 2 and Figure 3 A push plate 2 is provided inside the material collection box 1, and a sealing plate 3 is provided on the outside of the material collection box 1. The sealing plate 3 is used to seal the inside of the material collection box 1 to prevent waste from leaking out. A support frame 6 is provided on the outside of the upper end of the sealing plate 3, and the support frame 6 is fixed to the material collection box 1. A screw rod 5 is rotatably connected to the inner side of the support frame 6, and the other end of the screw rod 5 is rotatably connected to the material collection box 1, and a driving motor 51 is provided on the side of the outer end of the material collection box 1 away from the sealing plate 3. The output shaft of the driving motor 51 is connected to the screw rod 5. The specific connection method can adopt the existing technology, which can drive the screw rod 5 to rotate when the driving motor 51 is started. At the same time, the sealing plate 3 and the push plate 2 are both threadedly connected to the screw rod 5, which can drive the sealing plate 3 and the push plate 2 to translate at the same time when the screw rod 5 rotates, and the push plate 2 pushes out the waste accumulated in the material collection box 1 during the movement.

[0029] At the same time, the sealing plate 3 is opened and no longer blocks the collecting box 1, so that the waste is discharged from the collecting box 1. A discharge plate 13 is provided on the outer side of the lower end of the sealing plate 3. The discharge plate 13 is fixed to the collecting box 1. The waste discharged from the collecting box 1 is guided by the discharge plate 13, so that the transport vehicle can collect the waste discharged from the filter press in a unified manner.

[0030] Furthermore, a support frame 61 is fixed at the lower end of the support frame 6, and the other end of the support frame 61 is fixed to the support leg 12, so that the support for the support frame 6 is further improved by the support frame 61, and support rods 7 are respectively provided on both sides of the outer end of the aggregate box 1, and the head and tail ends of the support rod 7 are respectively fixed to the support frame 61 and the aggregate box 1, and mounting blocks 31 are respectively provided on both sides of the outer end of the sealing plate 3, wherein the support rod 7 runs through the interior of the mounting block 31, so that during the movement of the sealing plate 3, the sealing plate 3 is supported by the support rod 7, and at the same time, the movement of the sealing plate 3 is limited.

[0031] In a further embodiment, Figure 2 and Figure 4 A scraper is provided at the outer end of the push plate 2, which can drive the scraper to move while the push plate 2 pushes out the waste inside the collection box 1 by translation. The scraper includes a mounting plate 4 and a scraper frame 41. The mounting plate 4 is located on the outer side of the push plate 2, and the scraper frame 41 is fixed to the lower end of the mounting plate 4, and the scraper frame 41 is in contact with the collection box 1. During the movement of the scraper, the waste on the lower side of the collection box 1 can be scraped off by the scraper frame 41 to reduce the residual waste in the collection box 1.

[0032] Furthermore, two docking grooves 21 are provided on the outer side of the push plate 2 close to the mounting plate 4. At the same time, two docking blocks 8 are fixed on the outer side of the mounting plate 4, so that the mounting plate 4 can be clamped with the docking grooves 21 through the docking blocks 8. At the same time, a movable plate 9 is slidably connected to the inside of the push plate 2. A support block 22 runs through the inside of the movable plate 9. The support block 22 is fixed to the inside of the push plate 2, and the sliding of the movable plate 9 is limited by the support block 22. An adjusting rod 92 is threadedly connected to the other end of the movable plate 9. The adjusting rod 92 is rotatably connected to the inside of the push plate 2. The movable plate 9 can be driven to translate by rotating the adjusting rod 92. Two positioning rods 91 are fixed on the outer end of the movable plate 9 close to the mounting plate 4. After the adjusting rod 92 is rotated, the movable plate 9 can be driven to translate, and then the positioning rod 91 is clamped with the docking block 8 to complete the installation and fixation between the scraper and the push plate 2.

[0033] Among them, a fixing plate 921 is fixed to the outer end of the adjusting rod 92, and a cross slot is opened inside the fixing plate 921, so that the staff can connect tools such as screwdrivers with the cross slot of the fixing plate 921, and drive the fixing plate 921 to rotate the adjusting rod 92 by tools such as screwdrivers.

[0034] Working principle: After the waste of the filter press is discharged from the collecting hopper 11 into the collecting box 1, the waste is continuously collected by the collecting box 1. When the waste in the collecting box 1 is close to being full, the driving motor 51 is started to drive the screw 5 to rotate. At this time, the sealing plate 3 and the pushing plate 2 are translated at the same time, and the sealing plate 3 no longer blocks the collecting box 1. The waste is pushed out of the collecting box 1 by the pushing plate 2. The waste is uniformly discharged after being guided by the discharge plate 13. The discharged waste can be uniformly collected by a transport vehicle for transportation.

[0035] When the push plate 2 pushes the waste in the aggregate box 1 out, the scraper scrapes off the waste attached to the bottom of the inner end of the aggregate box 1 through the scraper frame 41, reducing the residual waste in the aggregate box 1. When the scraper needs to be cleaned or replaced, the adjusting rod 92 is reversed. At this time, the movable plate 9 translates horizontally, and the positioning rod 91 gradually moves away from the docking block 8. When the positioning rod 91 is no longer engaged with the docking block 8, the mounting plate 4 is moved upward as a whole, and the scraper can be removed from the push plate 2 as a whole, and the scraper can be replaced or cleaned as needed.
