[0002] During the fertilizer manufacturing process, the feces raw materials will be crushed first, and then the feces particles smaller than 1.5 mm will be considered qualified raw materials and will be transported to the granulator. The disc granulator or new granulator will support the round particles, and the feces particles larger than 1.5 mm will be transported back to the grinder for further crushing.

[0003] Therefore, it is necessary to filter and screen the freshly crushed feces raw materials, and screen out the raw materials larger than 1.5 mm and those smaller than 1.5 mm. At present, large particles are easy to block small particles during screening by screening equipment, and the feces raw materials will stick together, resulting in low screening efficiency. Feces with excessive adhesion are difficult to screen and need to be crushed again. Utility Model Content

[0004] In view of the problem mentioned in the above background technology that the current feces material screening equipment has the problem that the feces materials stick together and the screening efficiency is low, and it is difficult to separate and screen the feces materials with excessive adhesion, a screening equipment for fertilizer manufacturing is provided, which can make the feces materials looser and separate the feces materials with high viscosity.

[0005] The technical implementation scheme of the utility model is: a screening device for fertilizer manufacturing, including a base, four mounting frames are installed on the base, filter barrels are fixedly connected between the four mounting frames, a mounting column is rotatably connected in the middle of the base, and a filtering mechanism for filtering fecal particles is provided on the base and the filter barrel.

[0006] More preferably, the filtering mechanism includes a gear ring frame, the gear ring frame is slidably connected to the base, a motor is fixedly connected to the outer wall of the filter barrel, a column gear is fixedly connected to the output shaft of the motor, the gear ring frame is meshed with the column gear, and eight filter screens are slidably connected between the gear ring frame and the mounting column, and the mesh size of the filter screen is 1.5 mm.

[0007] More preferably, a shaking mechanism is further included, and the shaking mechanism includes a lifting frame, two of the lifting frames are fixedly connected to each of the filter nets, and the inclined block frame is fixedly connected to the inner wall of the filter barrel.

[0008] More preferably, an adjustment mechanism is also included, which includes a threaded column, four of the threaded columns are fixedly connected to the gear ring frame, an adjustment ring is slidably connected between the four threaded columns, a nut is threadedly connected to each of the threaded columns, the bottom of each nut is in contact with the top of the adjustment ring, and a pressure spring is connected between each of the ejector frames and the adjustment ring.

[0009] More preferably, two inclined blocks are arranged on the inclined block frame.

[0010] Compared with the prior art, the utility model has the following advantages: 1. When the gear ring frame rotates to drive the filter screen to rotate, one of the push frames on two symmetrically arranged filter screens will be squeezed by the inclined block frame, thereby driving the two symmetrically arranged filter screens to move upward. When the two push frames are separated from the inclined block frame, the two symmetrically arranged filter screens will instantly drop due to gravity and reciprocate in turn. This can shake the filter screen, making the fecal particles loose, making it easier to screen out fecal particles smaller than 1.5 mm, thereby improving the screening efficiency.

[0011] 2. When the feces are too sticky, the staff can adjust the nut to move the adjustment circle downward, thereby increasing the degree of compression of the pressure spring and then increasing the vibration amplitude of the filter. This can separate the feces particles with greater stickiness, thereby further improving the screening efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1: A screening device for fertilizer manufacturing, such as Figure 1-Figure 2 As shown, it includes a base 1, four mounting frames 2 are installed on the base 1, filter barrels 3 are fixedly connected between the four mounting frames 2, a mounting column 4 is rotatably connected in the middle of the base 1, and a filtering mechanism for filtering fecal particles is provided on the base 1 and the filter barrels 3.

[0018] The filtering mechanism includes a gear ring frame 5, which is slidably connected to the base 1, a motor 6 is fixedly connected to the outer wall of the filter barrel 3, a column gear 7 is fixedly connected to the output shaft of the motor 6, the gear ring frame 5 is meshed with the column gear 7, and eight filter screens 8 are slidably connected between the gear ring frame 5 and the mounting column 4, and the filter screen 8 is used to screen fecal particles entering the filter barrel 3, and the mesh size of the filter screen 8 is 1.5 mm.

[0019] It also includes a shaking mechanism, which includes a lifting frame 9. Two of the lifting frames 9 are fixedly connected to each of the filter screens 8. An inclined block frame 10 is fixedly connected to the inner wall of the filter barrel 3. The inclined block frame 10 is used to squeeze the lifting frame 9, so that the lifting frame 9 drives the filter screen 8 to move upward.

[0020] The staff first pours the feces particles that need to be filtered into the filter barrel 3, and then starts the motor 6. The output shaft of the motor 6 rotates to drive the column gear 7 to rotate, and the column gear 7 rotates to drive the ring gear frame 5 to rotate. The ring gear frame 5 rotates to drive eight filter screens 8 to rotate. The rotation of the filter screen 8 can screen the feces particles in the filter barrel 3 and filter out the feces particles smaller than 1.5 mm.

[0021] When the ring gear frame 5 rotates and drives the filter screen 8 to rotate, one of the push frames 9 on two of the symmetrically arranged filter screens 8 will be squeezed by the inclined block frame 10, thereby driving the two symmetrically arranged filter screens 8 to move upward. When the two push frames 9 are separated from the inclined block frame 10, the two symmetrically arranged filter screens 8 will instantly drop due to gravity and reciprocate in turn, which can shake the filter screen 8, making the feces particles loose, making it easier to screen out feces particles smaller than 1.5 mm, thereby improving the screening efficiency.

[0022] Embodiment 2: Based on embodiment 1, Figure 2-Figure 3As shown, an adjustment mechanism is also included, and the adjustment mechanism includes a threaded column 11. Four threaded columns 11 are fixedly connected to the gear ring frame 5. An adjustment ring 12 is slidably connected between the four threaded columns 11. A nut 13 is threadedly connected to each of the threaded columns 11. The bottom of each nut 13 contacts the top of the adjustment ring 12. A pressure spring 14 is connected between each of the ejector frames 9 and the adjustment ring 12. The nut 13 is used to adjust the height of the ejector frame 9, thereby adjusting the degree of compression of the pressure spring 14.

[0023] The inclined block frame 10 is provided with two inclined blocks.

[0024] When two of the symmetrically arranged filter screens 8 move upward, the pressure spring 14 will be squeezed. After the pushing frame 9 is separated from the inclined block frame 10, the pressure spring 14 will reset and drive the filter screen 8 to reset downward. When the feces are too sticky, the staff can adjust the nut 13 to move the adjustment ring 12 downward, thereby increasing the degree of compression of the pressure spring 14, and then increasing the shaking amplitude of the filter screen 8. In this way, the feces particles with greater adhesion can be separated, thereby further improving the screening efficiency.
