For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0031] Refer toFigure 1 As shown in the drawings, the embodiment provides an innovative rice hull-based ecological fertilizer production equipment, which comprises a base 1, an extrusion mechanism 2, a heating coil 3 and a hopper 4. The base 1 supports the extrusion mechanism 2, and the hopper 4 is arranged above the feeding side of the extrusion mechanism 2. The hopper 4 is used to contain the mixture of rice hulls and livestock manure.
[0032] Specifically, referring to Figure 2 As shown in the drawings, the extrusion mechanism 2 comprises an extrusion cylinder 21 and a spiral pressing rod 22, and the heating coil 3 is arranged around the periphery of the extrusion cylinder 21. The extrusion cylinder 21 is conical, and the imaginary circumscribed cylinder of the spiral pressing rod 22 has the same taper and inclination direction as the extrusion cylinder 21. The extrusion cylinder 21 is coaxially sleeved on the spiral pressing rod 22. The extrusion cylinder 21 is provided with a ventilation hole 211 corresponding to the area where the heating coil 3 is located.
[0033] In the embodiment, the mixture of rice hulls and livestock manure in the extrusion mechanism 2 is heated at high temperature by the heating coil 3, effectively killing the insect eggs contained therein. At the same time, the ventilation hole 212 is arranged at the heating area of the extrusion cylinder 21, which can realize the evaporation and drying of water vapor while killing insect eggs at high temperature, saving the subsequent drying process of solid fertilizer. The mixture of water vapor is directly made into dry solid fertilizer by the pushing and extruding of the spiral pressing rod 22 in the conical extrusion cylinder, improving the production efficiency.
[0034] It should be noted that the imaginary circumscribed cylinder of the spiral pressing rod 22 is equivalent to the outer edge position of the spiral pressing piece on it in the rotating process, which forms an outer connecting barrel in space.
[0035] The diameter of the ventilation hole 211 is selected to ensure that the mixture of rice hulls and livestock manure cannot overflow through the ventilation hole 211. Preferably, the diameter of the ventilation hole 211 is selected to be 3-5mm, and in the embodiment, it is selected to be 5mm. As another embodiment, the feeding side of the extrusion cylinder 21 and the part containing the ventilation hole 211 of the extrusion cylinder 21 can cancel the taper and select a cylindrical cylinder. When feeding, the feeding speed should be controlled, so that the material can be more effectively prevented from overflowing from the ventilation hole 211.
[0036] In the embodiment, the position of the extrusion cylinder 21 on the feeding side has a feeding port 212, and the heating coil 3 surrounds a section of the extrusion cylinder 21 close to the feeding port 212. The reason for setting a section here is mainly that the corresponding part of the extrusion cylinder 21 needs to be provided with a ventilation hole 211. In order to prevent the material from being extruded through the ventilation hole 211, the heating coil 3 needs to be arranged in the front half of the extrusion cylinder 21 where the extrusion effect is smaller.
[0037] Further, the ventilation hole 211 is circular or semi-lunar, or elliptical, and the axis of the ventilation hole 211 has an angle with the material advancing direction, and the angle is obtuse. Here, the material is also prevented from being squeezed out through the ventilation hole 211.
[0038] In the embodiment, the imaginary circumscribed cylinder of the screw press rod 22 has a spacing with the inner wall of the extrusion cylinder 21, and the spacing range is 1-2 mm. If the spacing is too large, the extrusion effect is not good; if the spacing is too small, the material is easily squeezed out.
[0039] Further, the large end surface of the extrusion cylinder 21 is detachably connected with an end cover 23, the end cover 23 is used to block the material on the feeding side, the small end surface is provided with a discharge port 213 for discharging. The screw press rod 22 extends outward from one end of the end cover 23 to form a rotating shaft 221, the rotating shaft 221 is connected with a driving device and a bearing fixing device is arranged therebetween. The driving device is used to provide power to the rotating shaft 221, and the bearing fixing device is used to support the screw press rod 22 and provide axial bearing action.
[0040] Referring to Figure 3 As shown, the bottom of the hopper 4 is provided with an opening corresponding to the feeding port 212, for the mixture of rice husks and human and animal excrement to pass through. A partition plate 41 is arranged in the interior of the hopper 4, for separating the rice husks and the mixture of human and animal excrement. Separate feeding can be achieved, which is convenient for operation.
[0041] As a preferred embodiment, a double-screw mixer can be added to the lower part of the hopper 4.
[0042] Referring to Figure 2 As shown, the embodiment also includes a U-shaped frame 5, the U-shaped frame 5 is provided with a guide port 51 at the top, and the hopper 4 is fixedly connected to the base 1 through the U-shaped frame 5, and the opening 41 and the guide port 51 correspond to each other to form a material passage.
[0043] Preferably, the opening 41 is respectively provided with an adjustable first material blocking piece 43 and a second material blocking piece 44, the first material blocking piece 43 is used to adjust the feeding of the rice husks, and the second material blocking piece 44 is used to adjust the feeding of the mixture of human and animal excrement.
[0044] In the embodiment, preferably, the heating coil 3 adopts a water-cooled electromagnetic induction coil and is configured with a power-adjustable power supply. The heating temperature can be accurately controlled and can be adjusted in real time.
[0045] In summary, the production process of the innovative rice husk-based ecological fertilizer production equipment is as follows:
[0046] First, the mixture of rice husk and human and animal excrement is placed in the hopper 4 and separated by the partition 42. The control power of the heating coil 3 is turned on and adjusted to the appropriate power. The feeding of the mixture of rice husk and human and animal excrement is controlled by adjusting the first baffle 43 and the second baffle 44, and the mixture of rice husk and human and animal excrement enters the guide opening 51 at the top of the U-shaped frame 5 through the opening at the bottom of the hopper 4, and then enters the inside of the extrusion cylinder 21 through the feeding opening 212 at the top of the extrusion cylinder 21.
[0047] Then, the driving device of the extrusion mechanism 2 is started, which drives the rotating shaft 221 to rotate, and the rotating shaft 221 drives the screw rod 22 to rotate, so as to mix and push the mixture of rice husk and human and animal excrement to the discharge opening 213. In this process, the material is heated to release water vapor when passing through the heating coil 3, and the water vapor is volatilized through the air hole 211. The dry solid mixed fertilizer obtained at the discharge opening 213 can enter the next process for crushing operation.
