Description

Technical Field

[0001] The utility model relates to the technical field of biological fertilizer processing, in particular to a multi-stage filtering device for biological fertilizer production. Background Art

[0002] The physical filtration of biofertilizer mainly removes large particles of impurities and suspended matter in the fertilizer through screens, sand filtration, etc. Screens with different mesh sizes are required for different screening requirements.

[0003] In the related art, a scheme of a biofertilizer screening device (Announcement No. CN219816956U) was found through searching, in which a motor drives a first sieve drum, a second sieve drum, and a third sieve drum to rotate synchronously, and the biofertilizer can be screened in multiple stages through the first sieve drum, the second sieve drum, and the third sieve drum.

[0004] However, in the above scheme, when the bio-fertilizer is screened, since the screening device is arranged at an angle, when the first sieve drum, the second sieve drum and the third sieve drum are rotating, the bio-fertilizer will be discharged before being screened and filtered. Moreover, this problem becomes more serious as more bio-fertilizer is added, and the bio-fertilizer needs to be circulated and filtered. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-stage filtering device for bio-fertilizer production to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a multi-stage filtering device for bio-fertilizer production, comprising a base, a bracket rotatably connected to the surface of the base, a support shaft rotatably connected to the bracket, a first filter cartridge installed on the surface of the support shaft, a second filter cartridge installed on the surface of the first filter cartridge, and a third filter cartridge installed on the surface of the second filter cartridge;

[0007] A motor is mounted on the surface of the bracket and is in driving connection with the support shaft to control the rotation of the first filter cartridge, the second filter cartridge, and the third filter cartridge. The first filter cartridge, the second filter cartridge, and the third filter cartridge can be rotated to filter the batch of biofertilizer three times to achieve multiple filtering.

[0008] An electric cylinder, the lower end of the piston rod of the electric cylinder is rotatably connected to the base, the outer shell of the electric cylinder is rotatably connected to the bracket, the first filter cartridge, the second filter cartridge, and the third filter cartridge are respectively provided with a first discharge pipe, a second discharge pipe, and a third discharge pipe on their surfaces, the first discharge pipe penetrates the second filter cartridge and the third filter cartridge, the second discharge pipe penetrates the third filter cartridge, the electric cylinder can lift the bracket, and thereby the first filter cartridge, the second filter cartridge, and the third filter cartridge can discharge some residual bio-fertilizer.

[0009] Furthermore, a first articulated seat is provided on the right side of the base surface, the lower end of the piston rod of the electric cylinder is connected to the first articulated seat, a second articulated seat is provided on the right side of the bracket, and the outer shell of the electric cylinder is connected to the second articulated seat, ensuring that the electric cylinder can smoothly control the tilt of the bracket to avoid jamming problems.

[0010] Furthermore, a plurality of fixing rods are provided on the surface of the support shaft, and the fixing rods are connected to the first filter cartridge, the second filter cartridge, and the third filter cartridge, thereby improving the structural strength of the first filter cartridge, the second filter cartridge, and the third filter cartridge, and preventing them from shaking when rotating.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The electric cylinder controls whether the first filter cartridge, the second filter cartridge, and the third filter cartridge are in a tilted state. When filtering a large amount of bio-fertilizer, it can ensure that the bio-fertilizer is fully filtered. When some residual bio-fertilizer needs to be discharged, the electric cylinder controls the first filter cartridge, the second filter cartridge, and the third filter cartridge to tilt and discharge the bio-fertilizer smoothly. This can ensure the single filtering effect without affecting the discharge of the residual bio-fertilizer, and is more convenient to use.

[0013] (2) Both ends of the first filter cartridge, the second filter cartridge, and the third filter cartridge are conical, which can prevent the biofertilizer from falling out during filtration, and is also convenient for adding biofertilizer and continuously filtering biofertilizer.
