It can be understood that, since the weight assembly is movably connected to the second shaft body 253, the weight assembly always returns to the lowest gravitational potential energy position, i.e., the lowest position of the center of gravity of the weight assembly with respect to the ground, under the action of its own weight, as long as the center of gravity of the weight assembly is not set to coincide with the central axis of the second shaft body 253. That is, the weight assembly functions as a tuned mass damper, so that the rolling roller 250 is stabilized while being passively rotated, preventing an excessive swing amplitude in the drum 200.
The gravitational potential energy of the rolling roller 250 is changed in the rotating process, so that the better rolling effect on the kitchen waste can be achieved by converting the potential energy into the kinetic energy. It is understood that the rolling roller 250 can be used not only for the treatment of kitchen waste, but also for the treatment of pulp or other solid-liquid mixtures.

In order to use the above-mentioned rolling roller 250 in the kitchen waste treatment, referring to fig. 3-6, 21 and 25, the rolling crushing member 200 according to the first embodiment of the present invention is used for crushing solid substances in a crushed solid-liquid mixture, and is characterized in that: the rolling crushing member 200 includes the roller body 220 and the rolling roller 250, wherein, referring to fig. 25, the roller body 220 has a cylindrical second inner cavity 214; the inner diameter of the roller body 220 is greater than the outer diameter of the rolling roller 250; the rolling roller 250 is freely movable in the second inner cavity 214 of the roller body 220 and always moves toward the gravitational potential energy lowest position in the second inner cavity 214 of the roller body 220 by its own weight; the roller body 220 rotates along its own central axis under the action of an external force, the lowest position of gravitational potential energy of the inner wall of the roller body 220 changes along with the rotation, and the rolling roller 250 reciprocates along the arc inner surface of the second inner cavity 214 relative to the roller body 220, so as to crush and crack solid substances in the solid-liquid mixture in the second inner cavity 214.
It will be appreciated that the solid-liquid mixture is, for example, kitchen waste, pulp, or other mixture of solids and liquids. The outer diameter of the laminating roller 250 can be understood as the outer diameter of the second intermediate cylindrical portion 256.
It is understood that the rolling crushing member 200 may be used alone as in the prior art, and only sealing plugs or sealing flanges are required to be installed at both ends of the roller body 220 to form the rolling crushing member 200 or the device. The rolling crushing member 200 may also be used as a component of a kitchen waste pulping apparatus described below, and only the connecting flanges with central openings are mounted at the two end portions of the roller body 220.
To ensure that the rolling roller 250 can move automatically in the roller body 220, the outer diameter of the rolling roller 250 is generally much smaller than the inner diameter of the roller body 220, for example, the outer diameter of the rolling roller 250 is 0.618 times, 0.5 times, 0.4 times, 0.382 times, 0.2 times the inner diameter of the roller body 220. The smaller the outer diameter of the rolling roller 250 is, the smaller the axial flow resistance to the kitchen waste is.
It can be understood that the roller body 220 is generally made of heavy metal such as iron or iron-based alloy, and therefore, the roller body 220 is provided with the second inner cavity 214 to facilitate adjusting the weight thereof according to different diameter dimensions, i.e. adjusting the average density of the roller body 220, so that the roller body 220 has an optimal disintegrating effect on the kitchen waste. The smaller the diameter of the roller body 220, the greater the wall thickness.
It can be understood that, in order to reduce the axial flow resistance to the kitchen waste, the laminating roller 250 with a streamlined design is most reasonable, but the manufacturing cost is too high, and the rotating body with the longitudinal section shape of the shuttle shape or the shuttle shape of the weaving machine is closer to the streamline shape, but the processing cost is lower. In other words, the rolling roller 250 comprises three parts, wherein the middle part is a section of cylinder, and the two ends are truncated cones, and the two truncated cones can be symmetrical bodies with the same size or asymmetrical arrangement.
The main body part of the rolling roller 250, that is, the cylindrical middle part of the rolling roller 250 is coated with a high polymer material cladding, so that the difference between the density of the rolling roller 250 and the density of the kitchen waste can be reduced, the disintegrating effect is improved, meanwhile, because the roller body 220 is also made of metal iron or iron-based alloy, the free and unconstrained relative movement of the rolling roller 250 and the roller body 220 is easy to cause direct collision between the two, and therefore, the high polymer material cladding also plays a role in buffer protection. The polymer material also has the advantage of corrosion resistance, and plays a role in corrosion protection for the rolling roller 250 in a severe garbage environment. The cavity design of the rolling roller 250 is also favorable for adjusting the average density of the rolling roller 250, and the rolling roller 250 can be dynamically changed by reconfiguring a plurality of small counter weights in the fourth inner cavity 254, so that the density distribution of the rolling roller 250 is further improved, and the better crushing effect on the kitchen waste is achieved.
The design concept of the end installation counterweight body of the rolling roller 250 is based on the stirring principle, the rolling roller 250 is based on the self weight, the roller body 220 is arranged near the lowest position of gravitational potential energy in the second inner cavity 214 to swing in a reciprocating manner, regular laminar flow of kitchen waste is easily formed, the stirring and crushing effects are not favorably achieved, and the counterweight body with the irregular shape can disturb the flowing of the kitchen waste, form turbulent flow and improve the stirring and crushing effects. Through first counter weight body pass through antifriction bearing with roll-in 250 swing joint just can form first counter weight body with roll-in 250's relative motion, more favourable upset kitchen garbage is in the flow of roll-in crushing part 200. The second shaft 253 extends out of one end or both ends of the rolling roller 250 by welding or screwing. A bearing hole seat is formed in one end of the first counterweight body, an outer ring of the rolling bearing is installed in the bearing hole seat in a tight fit mode, and an inner ring of the rolling bearing is installed on the second shaft body 253 in a tight fit mode.
The lamination roller 250 is freely movable in the second inner cavity 214 of the roller body 220 and always moves toward the gravitational potential energy lowest position in the second inner cavity 214 of the roller body 220 by its own weight. It can be understood that, just because the potential energy of the rolling roller 250 changes during the movement process, the effect of smashing and dropping the heavy object is achieved, and the gravitational potential energy is effectively converted into the effect of disintegrating the kitchen waste.
The roller body 220 rotates along its own central line under the action of external force, the lowest gravitational potential energy position in the second inner cavity 214 of the roller body 220 changes along with the rotation, and the rolling roller 250 reciprocates along the arc inner surface of the second inner cavity 214 relative to the roller body 220, thereby crushing and disintegrating solid substances in the solid-liquid mixture in the second inner cavity 214. It will be appreciated that the roller body 220 is rotated by the motor 206 and a friction or gear drive, and although the coordinates of the lowest point of the second interior cavity 214 of the roller body 220 in the rotational movement, i.e., the lowest potential energy point, with respect to the ground is not changed, the coordinates of the points on the surface of the second interior cavity 214 of the roller body 220 are changed with the rotational movement. Roller body 220 with the relative rotary motion of rolling roller 250 produces kitchen garbage's circumferencial direction's flow, and roller body 220 with the circumference runner between the rolling roller 250 is not even degree of depth, but similar wedge, consequently produces liquid compression in the direction of rotation, reaches fracturing, fragmentation the technical effect of solid matter in the kitchen garbage.
Preferably, as shown in fig. 25, the cross-sectional area of the lamination roller 250 is one-fourth to one-half of the cross-sectional area of the second inner cavity 214 of the roller body 220. The design point is that the flowing cross-sectional area of the kitchen waste in the rolling crushing part 200 cannot be too large, otherwise the treatment efficiency of the waste is affected, and the axial flow is hindered.
Preferably, a plurality of second solid weight bodies are disposed within the fourth interior cavity 254 of the lamination roller 250. It will be appreciated that the volume of each solid weight may be much smaller than the volume of the fourth inner cavity 254, so that the solid weight can roll freely in the fourth inner cavity 254, thereby dynamically changing the density distribution of the crushing roller 250, and the density change will result in the efficiency of converting potential energy into kinetic energy being maximized according to the principle of minimum potential energy, thereby generating better garbage crushing effect.
Preferably, the second shaft 253 traverses the rolling roller 250 and protrudes at both ends of the rolling roller 250, and the weight assembly is mounted on the second shaft 253 at the end of the rolling roller 250. It is understood that the weight assembly may be one or two, and thus the structure and arrangement of the second shaft body 253 are different. The second shaft 253 extends longitudinally through the fourth inner cavity 254 of the laminating roller 250 in a compact arrangement, and is fixed and supported by the sealing flanges at the two ends of the laminating roller 250. Even if the second shaft body 253 protrudes at both end portions of the laminating roller 250, the weight assembly may be mounted only at one end of the second shaft body 253, and the weight assembly may not be mounted at the other end.
Preferably, the weight assemblies are two and are respectively mounted on the second shaft 253 at both ends of the rolling roller 250. It can be understood that, two counterweight assemblies are symmetrically installed at two ends of the rolling roller 250, so that the movement balance of the rolling roller 250 can be ensured, excessive axial movement cannot be generated, and the safe and reliable operation of the equipment can be ensured.
Preferably, a center line of the second shaft body 253 coincides with a center axis of the first cylinder body 252. It is understood that the combined structure with the coincident center lines is the most stable, and the motion uncertainty of the combined structure of the second shaft body 253 and the roller body 220 can be reduced. Optionally, the centerline of the second shaft 253 is parallel to but not coincident with the central axis of the roller body 220, such a configuration may generate more uncertain turbulence of the kitchen waste, which is beneficial to improve the waste disposal effect.
Preferably, the first weight body has a dumbbell shape. It can be understood that the dumbbell shape is relatively complex, so that the regular flow of the kitchen waste is disturbed, and the waste disintegrating efficiency is improved. Optionally, the first counterweight body is in a cross shape, a triangle shape or a Y shape.
Preferably, the polymer material cladding is made of rubber, plastic and carbon fiber. It can be understood that the high polymer materials have better acid or alkali corrosion resistance, and are very suitable for the use environment of kitchen waste treatment. Carbon fibers have excellent strength and wear resistance, but are expensive to produce.
Preferably, a plurality of first convex bodies are distributed on the surface of the high polymer material cladding. It will be appreciated that the first convex hull facilitates disintegration of solid matter of organic matter. Optionally, the first convex body is provided with a knife edge part in the lateral direction, so that solid matters of organic matters in the garbage can be crushed.
Preferably, a plurality of second convex bodies are arranged on an outer surface of the first balance weight body of the weight assembly. It can be appreciated that the second convex body can increase the complexity of the shape of the first counterweight body, increasing the turbulence effect.
Preferably, referring to fig. 25 and 28, both ends of the roller body 220 of the rolling crushing member 200 are provided with a limiting member for limiting the axial movement of the rolling roller 250. It will be appreciated that the spacing member may be in the form of, for example, an annular body, a cross-body or a well-type body. Such a design can prevent the rolling roller 250 from moving or shifting in the axial or longitudinal direction, which may affect the normal operation of other components.
As shown in fig. 25 and 28, the limiting component is a plurality of trapezoidal plate pieces arranged along the inner wall of the roller body 220, wherein the lower bottom edge of each trapezoidal plate piece is fixedly connected with the inner wall of the roller body 220, and at each end of the roller body 220, a first circular channel hole is defined by the upper bottom edges of the trapezoidal plate pieces, and the diameter of the first circular channel hole is larger than the outer diameter of the rolling roller 250. Such trapezoidal sheets facilitate axial or longitudinal flow of the kitchen waste. Optionally, the length of the upper base of the trapezoidal plate is zero, so that the trapezoidal plate is a triangular plate. Preferably, the trapezoidal plate sheets are arranged to intersect the cylindrical busbars of the roller bodies 220 clockwise or counterclockwise at a first determined included angle, which is, for example, 0 ° to 30 °, preferably 5 °, 10 ° or 15 °, and the selection of the first determined included angle clockwise or counterclockwise is related to the rotation direction of the roller bodies 220, and the fundamental technical effect is that the inclination of the trapezoidal plate sheets is beneficial to pushing the waste materials from upstream to downstream.
