According to a first preferred embodiment of the kitchen waste repulping treatment apparatus of the present invention, referring to fig. 1 to 28, the kitchen waste repulping treatment apparatus comprises a spiral conveying member 100, a rolling crushing member 200 as described herein, and a spiral screening member 300, wherein the kitchen waste is a solid-liquid mixture. The ends of the screw conveying member 100, the rolling crushing member 200, and the spiral screen member 300 are fixedly connected together to form a drum assembly; the spiral conveying member 100 is provided with a first inner cavity 106, the rolling crushing member 200 is provided with a second inner cavity 214, the spiral screening member 300 is provided with a third inner cavity 314, and the three inner cavities are sequentially communicated together; the spiral conveying part 100 can transmit the kitchen waste to the rolling crushing part 200 under pressure; the rolling crushing component 200 can crush and crack solid substances in the kitchen waste; the spiral screening component 300 can screen and separate solid substances and liquid substances in the kitchen waste; the first end of spiral conveying part 100 is provided with feed inlet 105, spiral screening part 300 is provided with the discharge gate, kitchen garbage follows feed inlet 105 gets into among the kitchen garbage fragmentation slurrying treatment facility, through fragmentation, slurrying, solid-liquid separation back, follow the discharge gate is discharged. Advantageously, the outlet ports may be an off-gas collection port, the accept slurry outlet 318, and a solid waste outlet 316.

It can be understood that the three-section design is reasonable, the requirements of the kitchen waste on crushing, slurrying, screening and washing and separation treatment can be basically met, the design of the driving part is simple, and the driving power is reasonable. The length of the whole kitchen waste pulping treatment equipment is about 20 meters, preferably in the range of 10 meters to 20 meters, and the diameter of the whole kitchen waste pulping treatment equipment is 2.4 meters, and can be larger. If a four-stage or five-stage design is adopted, the processing function is more complete, but the driving device is very complex, the power consumption is huge, the requirement on the electronic equipment is higher, and the manufacturing cost is increased.

Referring to fig. 3-6, 24, 25, a first embodiment of a rolled crushing member 200 according to the present invention for crushing solid matter in a crushed solid-liquid mixture is characterized in that: the rolling crushing member 200 includes a roller body 220 and a 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.

Referring to fig. 18, 19, 20 and 21, according to an embodiment of the laminating roller 250 of the present invention, the laminating roller 250 includes a first cylinder 252, a first weight member and a second weight member. Referring to fig. 18, 19 and 20, the first cylinder 252 may have a cylindrical, shuttle-shaped, or elliptical-cylindrical shape, which is capable of rolling back and forth within the cavity of, for example, a cylindrical roller. The second weight member is used for increasing the weight of the rolling roller 250, so that the rolling effect on the kitchen waste is increased. The second weight member may be a plurality of weight spheres, weight cylinders, or weight blocks, freely placed within the barrel, advantageously having the structure and features described below.

Referring to fig. 21, the first cylinder 252 has a closed fourth internal cavity 254, and the second weight member is mounted in the fourth internal cavity 254. It will be appreciated that the first cylinder 252 is sealed at both ends by first and second lamination roller sealing plates 258,259 whereby the interior of the first cylinder 252 defines the fourth internal cavity 254, and that the first and second lamination roller sealing plates 258,259 are advantageously releasably and sealingly connected to the first cylinder 252 for timely installation and maintenance of the second weight member in the fourth internal cavity 254.

The first weight member includes a dumbbell-shaped first weight body (not shown in the drawings), and is fixedly or movably attached to the outer end surface of the first cylinder 252. The first counterweight 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. One end of the dumbbell body of the first weight body may be welded directly to the outer end face of the first cylinder 252 such that the longitudinal axis of the dumbbell body of the first weight body is parallel to the central axis of the first cylinder 252. The dumbbell main body of the first weight body can also be movably connected to the outer end face of the first barrel 252 through a first rod body and a rolling bearing or a sliding bearing, wherein the first end of the first rod body is welded to the middle of the dumbbell main body of the first weight body, and the second end of the first rod body is connected to the outer end face of the first barrel 252, so that the longitudinal axis of the dumbbell main body of the first weight body is parallel to the outer end face of the first barrel 252. Therefore, the first balance weight body is in a cross shape, a triangular shape or a Y shape. The first weight member may be fixedly or movably attached to the outer end surface of the first cylinder 252 along the central axis of the first cylinder 252, or may be attached to the outer end surface of the first cylinder 252 near the central axis of the first cylinder 252. The first weight member may be attached to one of the outer end surfaces of the first cylinder 252, or one first weight member may be attached to each of the two outer end surfaces of the first cylinder 252.

Referring to fig. 20 and 24, the second weight member includes a second shaft 253 and a weight assembly, wherein the second shaft 253 is fixedly or movably connected with the first cylinder 252, and the weight assembly is movably or fixedly connected with the second shaft 253. It is understood that the second shaft 253 and the first cylinder 252 may be fixed together by welding or screwed together. Preferably, as shown in fig. 20, the second shaft 253 and the first cylinder 252 are connected together by a first rolling bearing 265. The weight member is, for example, a weight with a hole, which is movably sleeved on the second shaft 253, and the weight with a hole can also be movably connected with the second shaft 253 through a rolling bearing. Alternatively, in the case that the second shaft 253 is movably connected to the first cylinder 252, the weight with the hole may be fixedly connected to the second shaft 253. Preferably, the weight assembly has the structure and attachment means described below.

Referring to fig. 24, the second weight member is arranged such that: when the rolling roller 250 rotates, the weight assembly can swing or rotate with respect to the second shaft 253, so that the center of gravity of the rolling roller 250 as a whole is maintained at a low position. 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.

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 is welded or screwed to one end or both ends of the rolling roller 250. 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.

The sealing and rotational connection between the feed inlet 105 and the first end of the spiral conveying member 100 can be referred to in patent document CN204644757U, and it is obvious that the connection is preferably a rotational sealing connection because the drum assembly rotates during operation and the feed inlet 105 remains stationary, and such a connection in the prior art can be supported by the prior art solution of the present invention as long as it can be used in the present invention, and in the present embodiment, the connection between the feed inlet 105 and the first end of the spiral conveying member 100 can be a prior art connection or a connection described below. Similarly, the discharge port may be connected to the second end of the spiral screening member 300 in a rotary sealing manner. Since the kitchen waste is subjected to solid-liquid separation, the discharge hole generally refers to a discharge hole for solid materials, while the discharge hole for liquid materials generally refers to a sieve hole, and the collecting device may not be directly connected to the drum assembly, but rather be located at the downstream end of the spiral screening member 300, and the liquid materials directly flow to the collecting device from the spiral screening member 300.
