An embodiment of the organic waste treatment apparatus according to the present invention will be described with reference to fig. 1 to 5B.

As shown in fig. 1, embodiments of the present invention provide an organic waste management device 10, which organic waste management device 10 may generally include a trommel 12 and at least one hammering member 14. As shown, the hammering member 14 may be located in the screening area S of the trommel 12, and the hammering member 14 is mounted on a screen 16 of the trommel 12, and under the action of the screen, the garbage may be repeatedly swung and hammered as the screen 16 rotates. It should be understood herein that the screening zone S as described above refers to an area inside the trommel 12 where the organic waste material is received and screened.

During use of the organic waste treatment device 10, when the screen 16 is driven to rotate by a driving device such as a motor (described below), the screen 16 drives the hammering member 14 to repeatedly swing and hammer the waste as it rotates. At this time, the organic waste in the trommel 12 is hammered and compressed by the hammering member 14 by the rotation of the screen 16. In this way, the hammering member 14 is enabled to sufficiently crush and dewater the organic waste.

As further shown in fig. 1 in conjunction with fig. 2, in one embodiment of the present invention, organic waste treatment device 10 may include at least one pair of peening members 14. In this embodiment, the peening members 14 and the screen 16 may be connected by connecting rods 18, and each pair of peening members 14 may be connected by a spring 20 therebetween. In one embodiment, the connecting rod 18 may be fixedly connected to the screen 16 by a fastener 182, such as a bolt, rivet, or the like. In another embodiment, the elastic member 20 may be a member such as a spring; it should be understood that other members having the same elastic properties may be used as the elastic member in the present invention.

In this case, the resilient member 20 may exert a force on the hammering member 14, so that the crushing effect is more sufficient. That is, when one of the pair of hammering members 14 contacts the garbage, a force is applied to the elastic member 20, and the elastic member 20 transmits the force to the other hammering member, so that the force is transmitted to the garbage again. This further optimizes the crushing effect of the waste.

In a further alternative embodiment, the organic waste treatment device 10 of the present invention may further comprise a plurality of pairs of hammering members 14, and the plurality of pairs of hammering members 14 may be spirally distributed on the screen 16 along the rotation axis a of the trommel 12 about which the screen 16 of the trommel 12 rotates. By this arrangement, the hammering members 14 distributed spirally over the whole of the inner surface of the screen 16 are distributed, so that the organic waste can be sufficiently crushed over the whole length of the screen 16, and the hammering members 14 located downstream in the conveying direction of the waste material can perform a lifting action on the waste in the upstream direction, so that the crushing is more sufficient.

In the embodiment shown in fig. 2, the exterior of the elastic member 20 as described above may be enclosed by a protective sheath 22. In one embodiment, the protective sleeve 22 fixed on the elastic member 20 may be a rubber protective sleeve with folded corrugations, which can be compressed or extended simultaneously with the compression or extension of the elastic member 20, thereby protecting the elastic member 20.

Referring now to fig. 1, 2 in conjunction with fig. 3, in one embodiment of the present invention, the connecting rod 18 may be hung on the screen 16 by a hanging ring 24. In use, the screen 16 is rotated by the motor, and then the screen 16 moves along the connecting rod 18 mounted on the screen 16 through the hanging ring 24, so that the hammering member 14 mounted on the connecting rod 18 swings repeatedly to perform crushing operation.

In an alternative embodiment, as shown in fig. 3, a limit stop 26 may be installed in the hanging ring 24, and the limit stop 26 may limit the swing stroke of the connecting rod 18. In particular, since the connecting rod 18 is swingably mounted on the eye 24, it will swing with respect to the whole of the eye 24 during use; if the connecting rod 18 swings at an excessive angle, the hammering member 14 connected thereto may be caused to strike the inner surface of the screen cloth 16 excessively, possibly causing abrasion or damage to the screen cloth 16. In this way, a limit stop 26 is mounted in the suspension ring 24, which can be arranged in the pivoting path of the connecting rod 18 as required by the pivoting angle. When the connecting rod 18 swings sideways to a maximum stroke, the connecting rod 18 will abut the limit stop 26, at which point the connecting rod 18 no longer swings further, thus preventing it from hitting the screen 16 too much.

In the embodiment shown in FIG. 3, the retainer stop 26 is provided in a configuration such as a V-shaped plate; in other embodiments, not shown, the limit stop 26 may also be two separate plates disposed at separate and angular positions; or may take the form of a stop protrusion or bump. In other words, the present invention is not limited to a specific embodiment as long as the limit stopper 26 can limit the swing stroke of the connecting rod 18.

Referring now to fig. 1, 2, and in conjunction with fig. 4, in one embodiment, each hammering member 14 may comprise a body 142, a protrusion 144, and a hammer pin 146. Wherein the body 142 is connected to the screen 16 (e.g., via the connecting rods 18), the projections 144 are disposed on the body 142 and the hammer pins 146 are disposed on the projections 144. By this arrangement, the contact area of the organic waste material with the hammering member 14 can be increased, so that the crushing effect is better.

In an alternative embodiment, the bodies 142 of the peening members 14 may be spherical (as shown in fig. 1, 2 and in conjunction with fig. 4), and a plurality of protrusions 144 may be provided on each body 142, and a plurality of hammer pins 146 may further be provided on each protrusion 144. It should of course be understood that the shape of the body 142 of the peening member 14 may be any feasible shape, such as various polyhedrons; further, the number of hammering members 14, the number of protrusions 144, and the number of hammer pins 146 may be set according to a specific use case, and the present invention does not impose any particular limitation on the above shapes and numbers.

Referring now to FIG. 1 in conjunction with FIG. 2, in one embodiment of the present invention, the organic waste management device 10 further may include a cleaning brush 28 mounted on the trommel 12. Specifically, the bristles of the washing brush 28 are in contact with the outer surface of the mesh 16 and rotate together with the mesh 16. In other words, the washing brush 28 may be arranged parallel to the rotation axis a of the drum screen 12, and the bristles contact the mesh screen 16 to brush the mesh screen 16. The screen 16 can be cleaned using the washing brush 28 in such a manner as to prevent the dirt from clogging the mesh of the screen 16 by mounting the washing brush 28 on the trommel 12 such that the bristles of the washing brush 28 are brought into contact with the outer surface of the screen 16 and rotated together.

In an alternative embodiment, the cleaning brush 28 may be a wire brush; it should be understood, of course, that other materials for the cleaning brush 28 are possible and the present invention is not limited thereto. Alternatively, the bristles of the washing brush 28 may rest against the outer surface of the mesh 16 and a portion of the bristles may extend into the mesh 16 such that the bristles are in sufficient contact with the mesh 16 to facilitate adequate cleaning.

referring now to FIG. 2, in one embodiment of the present invention, the organic waste management device 10 may further include a cleaning device 30. In the illustrated embodiment, the washing device 30 may include a washing liquid pipe 32 and a nozzle 34 provided at one end of the washing liquid pipe 32, and the nozzle 34 may be disposed toward the washing brush 28. During use, the nozzle 34 of the cleaning device 30 may spray cleaning fluid (e.g., water or any other feasible cleaning fluid) toward the cleaning brush 28. In this way, the cleaning device 30 can not only wash the surface of the screen after cleaning the cleaning brush 28 so that the surface is free from adhesion of garbage, but also perform operations of dewatering and deoiling and salting on the garbage inside.

According to the above description, the treatment device of the present invention can also realize multiple functions, namely, the organic waste is broken by the hammering component, the waste on the surface of the screen is cleaned by the cleaning brush, the cleaning device is used for washing the surface of the screen after the cleaning brush is cleaned, so that the surface is not sticky, and the internal waste is dewatered and deoiled to form salt, thereby effectively shortening the treatment process of the organic waste and reducing the investment and treatment cost of a treatment plant.

With continued reference to fig. 2, in one embodiment of the present invention, the organic waste management device 10 may further include a cover 36 disposed outside the trommel 12 and surrounding the trommel 12. As shown, the top of the housing 36 may be provided with an opening partially receiving the washing brush 28 so that the bristles of the washing brush 28 contact the outer surface of the mesh 16, and the bottom of the housing 36 may be connected with a sump tank 38 to collect separated water and oil salt. It is understood that the header tank 38 may be formed as part of the cover 36, i.e., the cover 36 and header tank 38 are integrally formed; or the sump tank 38 may be a separate component separately disposed below the housing 36. This may be the case, and the present invention is not limited thereto.

With continued reference to fig. 2, in the illustrated embodiment, the organic waste treatment device 10 may further include a material raising plate 40 mounted on an inner surface of the screen 16. When the screen 16 rotates, the organic garbage materials move along with the cylinder in the same direction, the organic garbage materials roll under the action of the material raising plate 40, and the rolled organic garbage materials are looser, so that the organic garbage materials are beneficial to crushing and dewatering.

referring now to fig. 5A and 5B in conjunction with fig. 1, in one embodiment of the present invention, the organic waste management device 10 may further include a motor 42 coupled to the screen 16 to rotate the screen 16. Further, the motor 42 may also be coupled to the washing brush 28 through a linkage to drive the washing brush 28 to rotate.

In the embodiment shown, the linkage may include a pair of friction wheels 422, 424 connected directly to the spindle of the motor 42 and another pair of friction wheels 426, 428 connected to the washing brush 28. The two pairs of friction wheels may be drivingly connected to each other by any feasible means (e.g., a belt) to effect rotation of the screen 16 and the washing brush 28 by the motor 42. In this way, it is possible to simultaneously and synchronously rotate the screen 16 and the washing brush 28 by using only one motor 42, thereby saving the cost of the equipment.

In alternative embodiments, the linkage may also include any other possible structure, such as a linkage, a chain mechanism, etc. In other words, it is sufficient that the rotation of the screen 16 and the washing brush 28 can be simultaneously and synchronously realized, which depends on the specific use case, and the present invention is not limited to any particular case.

In a particular use of the invention, the trommel 12 is inclined and positioned on a fixed support with the feed port 44 being higher than the discharge port 46. In addition, access ports 50 may be provided in the trommel 12 for access or maintenance to the interior of the trommel 12. The organic waste material is fed into the processing apparatus through the feed inlet 44 and is screened by rotation of the screen 16, while the organic waste material is hammered and crushed by the hammering member 14 in the screen 16. At the same time, the operations of dehydration and desalting are performed by the combined action of the washing brush 28 and the washing device 30, and the collected water, oil salt, and the like flow into the header tank 38 to be collected. The treated organic waste can be discharged to a belt conveyor 48 through a discharge port 46 and directly enter a subsequent aerobic drying treatment system through transportation. Therefore, the treatment device of the invention effectively shortens the treatment process of the organic garbage and reduces the investment and treatment cost of treatment plants.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
