Description

Waste disposal device equipped with a drum for a conveyor belt that enhances the convenience of maintenance}

The present invention relates to a waste treatment apparatus having a drum for a conveyor belt with enhanced maintenance convenience, and more particularly, a drum of a conveyor belt that transports waste from the waste treatment apparatus, in the concept of a drum shaft and a main body. It relates to a waste treatment device equipped with a drum for a conveyor belt, which is designed with a drum shaft and can be replaced conveniently and easily, thereby enhancing the convenience of maintenance.

A waste treatment device is a device that treats building waste such as sludge, household waste such as food waste, and industrial waste such as scrap iron.

Such a waste treatment device may have various purposes and structures depending on the type of waste. For example, drying food waste to reduce odor and volume, dispersing air to remove foreign substances attached to waste, or using a press machine, etc. By compressing waste with a compressor, it can be transformed into a structure that is easy to recycle by reducing its volume.

1 is a conceptual diagram illustrating a schematic structure of a known waste treatment apparatus, and FIG. 2 is a conceptual diagram illustrating a drum installed on a known conveyor belt.

The known waste treatment apparatus may have various structures and functions as mentioned above, but in FIG. 1, the most basic structure is exemplified. Specifically, the waste treatment apparatus includes a hopper 1, a treatment unit 2, and a conveyor belt ( 10) shows the structure.

The hopper 1 provides a function of mixing or pulverizing/drying waste while securing a space for accommodating the waste. At this time, the hopper 1 may have a function of not only mixing wastes but also drying/pulverization, but it has a simple structure and performs only a function of mixing wastes, and a separate unit, that is, for drying/pulverizing/sorting wastes in a separate unit, that is, the processing unit 2 It is also possible to carry out these specific processing tasks with a detailed structure.

The conveyor belt 10 transfers waste from the hopper 1 to the processing unit 2 or transfers the waste from the hopper 1 to the processing unit 2 by placing the waste on the belt 11 and moving it to the hopper 1 or the processing unit 2 It plays a role of discharging/moving the finished waste to the outside.

In other words, the conveyor belt 10 provides a convenient function to automatically move the waste from each unit while reducing the hassle of manually inputting or discharging waste into the hopper by the operator.

Such a conveyor belt 10 generally includes a belt 11 having a length corresponding to the distance through which the waste must travel, a roller 14 positioned between the rolled belt 11 and rotating, and the belt 11 . It consists of a drum 15 installed at at least one end of the , and a motor 12 connected to the drum 15 via a chain 13 to rotate the drum 15 . At this time, it is possible to mount a sprocket to which a chain can be connected to the drum 15 in a state where the drum shaft is provided.

That is, the drum 15 is a central component that drives the belt while being rotated by directly receiving the power of the motor 12. When the conveyor belt 10 is driven for a long time, the drum shaft is bent or deformed. Periodically, it is necessary to replace the drum shaft to balance the drum horizontally or to ensure durability.

However, as can be seen from FIG. 2 , the known drum 15 has a drum shaft integrally coupled with the body, so that even when only the drum shaft needs to be replaced, the hassle and economic loss of replacing the entire drum followed.

It can be said that mounting a conveyor belt in the current waste treatment device is almost essential for automation. Referring to the domestic prior art, the construction waste treatment device using air, which is a domestic patent No. 1427849, also uses a conveyor belt to apply air to waste. It has been disclosed to efficiently remove foreign substances from waste by spraying.

However, in this prior art, there is no description or illustration of whether the drum body of the conveyor belt and the drum shaft are integrally coupled, so there is no particular solution for replacing only the drum shaft.

Therefore, in the conveyor belt that transports waste from the waste treatment device, the drum shaft is separated from the base, which is the body, and then efficiently combined. The reality is that there is a need to develop new and advanced drums that can provide

The present invention has been devised to overcome the problems of the above technology, and the structure of the drum mounted on the conveyor belt of the waste treatment apparatus is separated into a base, which is a body, and a drum shaft assembly that is detachably coupled through fastening of fasteners on the base. Its main purpose is to provide a waste treatment device that can be configured to facilitate convenient replacement of the drum shaft.

Another object of the present invention is to provide a structure capable of reinforcing the durability of the drum shaft by appropriately distributing the external force acting on the drum shaft in the coupling structure of the drum shaft and the base.

Another object of the present invention is to provide a buffer plate made of an elastic material for preventing the drum shaft or the base from being easily deformed by the pressure acting on the drum shaft.

It is a further object of the present invention to add a functional composition capable of reinforcing durability to the above-mentioned burlap plate.

In order to achieve the above object, a waste treatment apparatus having a drum for a conveyor belt with enhanced maintenance convenience according to the present invention is a belt on which the waste is seated and the belt wound in order to move or discharge the waste to a hopper. In the waste treatment apparatus having a conveyor belt comprising a drum having a drum shaft that receives the rotational power of the motor via a chain, the drum has a cylindrical shape, and has a plurality of first fastening grooves along the circumference at one end. A recessed base and a second fastening groove that is detachably coupled to one end of the base, a plurality of penetrating second fastening grooves at a position corresponding to the first fastening groove at regular intervals along the circumference in a state of taking the shape of a disk It consists of a drum shaft assembly having a base plate provided with a base plate and a drum shaft extending by a predetermined length from the center of the base plate, and fastening fasteners to the first and second fastening grooves so that the drum shaft assembly is detachably attached to the base characterized by binding.

In addition, a coupling hole is recessed in the central portion of the base, and a coupling block having a diameter corresponding to the coupling hole is formed in the central portion of the surface of the base plate facing the base, so that the drum shaft assembly is It is characterized in that the coupling hole and the coupling block are coupled when coupled to the base.

In addition, the drum is made of an elastic material and is positioned between the base and the drum assembly, and has a diameter corresponding to the base plate and a position corresponding to the first and second fastening grooves at regular intervals along the circumference. It characterized in that it comprises a buffer plate through which a plurality of third fastening grooves are formed.

According to the waste treatment apparatus having a drum for a conveyor belt with enhanced maintenance convenience according to the present invention,

1) The drum shaft (drum shaft assembly) can be conveniently separated and replaced from the base, enhancing the convenience and economic feasibility of maintenance;

2) By presenting a detailed structure that assists in the coupling of the drum shaft assembly and the base, the drum shaft assembly can be more firmly coupled to the base,

3) Not only can the external force acting on the drum shaft assembly be appropriately distributed through the auxiliary groove,

4) The pressure applied to the drum shaft assembly through the buffer plate is also appropriately dispersed or absorbed, thereby enhancing the durability of the drum shaft assembly.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing refer to like elements.

Figure 3 is an exploded perspective view showing a basic embodiment of the drum of the present invention, Figure 4 is a perspective view showing a structure in which the base and the drum shaft assembly in Figure 3 are combined.

First of all, the waste treatment apparatus of the present invention provides a function of pulverizing various wastes such as construction/living waste, removing foreign substances, compressing, and drying, and the detailed structure for these functions is the same as the known technology, so a separate description is omitted. And, the conveyor belt 10, which transfers waste to the hopper 1 or discharges / moves from the hopper 1 or the processing unit 2 to the outside, is also limited to a specific structure if the structure is provided with the drum 100 In addition, the detailed structure of the conveyor belt 10 is also the same as or similar to the known technology, so a separate description will be omitted.

As can be seen from FIGS. 3 and 4, the drum 100 of the present invention, which is connected to a motor through a chain on the conveyor belt and transmits rotational force to the belt while rotating, is largely separated into a base 200 and a drum shaft assembly 300. It is based on the composition of

The base 200 is a structure extending in a direction and length corresponding to the width direction and length of the belt 11 made of a cylindrical structure with the exception of the known drum shaft.

A plurality of first fastening grooves 210 are recessed at one end or one surface (the upper surface or lower surface based on the cylindrical structure) of the base 200 at regular intervals along the circumferential direction. Although the first fastening groove 210 will be described later, it provides a space for the fastener F to be inserted together with the second fastening groove 311 and additionally a thread is formed on the inner circumferential surface so that the threaded fastener F is coupled. to ensure the stability of the bond.

The drum shaft assembly 300 includes a base plate 310 and a drum shaft 320 .

The base plate 310 is formed in a disk shape, and may have the same diameter as one surface of the base 200 on which the first fastening groove 210 is formed, or may have a smaller diameter.

The base plate 310 also has a plurality of second fastening grooves 311 formed at predetermined intervals along the circumferential direction of the number and at positions corresponding to the first fastening grooves 210 . However, the second fastening groove 311 has a difference in that the first fastening groove 210 is penetratingly formed, unlike the recessed one.

The drum shaft 320 refers to a central portion of the base plate 310 , that is, an axis extending in a direction opposite to the direction toward the base 200 in a state having a predetermined diameter and length from the center.

Although not shown in the drawing, the drum shaft 320 is equipped with a sprocket along the outer peripheral surface, and the chain 13 connected to the motor 12 shown in FIG. 1 is mounted thereto to receive the power of the motor 12. it is possible

The above-described base 200 and the drum shaft assembly 300 can be coupled and separated through a fastener F having a known shape such as a bolt or an anchor, and specifically, the first and second fastening grooves ( 210, 311) can be coupled or separated while making surface contact with each other in a manner of fastening and separating the fasteners (F).

According to this structure, even if the drum shaft 320, on which the external force is concentrated the most, including the power of the motor, is damaged/deformed, only the drum shaft assembly 300 can be separated from the base 200 and replaced, so that the drum 100 And furthermore, it provides a characteristic that the maintenance of the conveyor belt 10 or the waste treatment device is convenient and economic cost reduction can be pursued.

5 is an exploded perspective view illustrating a first modified embodiment of the drum in which a coupling hole and a coupling block are added.

Referring to FIG. 5 , the coupling hole 220 is recessed in the central portion of the base 200 , and correspondingly, the coupling hole 220 is formed in the central portion of the surface facing the base 200 from the base plate 310 . It can be seen that the coupling block 312 of a cylindrical shape having a corresponding diameter is formed.

Through this, when the drum shaft assembly 300 is coupled to the base 200, the coupling hole 220 and the coupling block 312 are unevenly coupled. At this time, threads are formed on each of the inner circumferential surface of the coupling hole 220 and the outer circumferential surface of the coupling block 312 so that the coupling block 312 is screwed into the coupling hole 220 while rotating the base plate 310 while the base 200 ) and the base plate 310 can be tightly coupled.

According to this structure, compared to the structure shown in FIG. 3, that is, the coupling structure between the base plate 310 and the base 200 that are in surface contact, the coupling area is increased to exhibit a more stable coupling force as well as the first and second coupling grooves. It is possible to prevent a phenomenon in which coupling fatigue is concentrated on the fasteners (F) fastened to (210, 311).

6 is a conceptual diagram illustrating a second modified embodiment of the drum to which auxiliary holes are added.

As can be seen from FIG. 6 , an auxiliary groove 313 may be formed on a surface facing the base 200 among two surfaces excluding the side surface of the base plate 310 .

This auxiliary groove 313 can be said to be a hole recessed to a predetermined depth, specifically, it is composed of a slit 313a and a sub-hole 313b.

The slit 313a is an imaginary line on which the second fastening groove 311 is formed, that is, a recessed hole extending in the circumferential direction and recessed between the second fastening grooves 311, and the sub hole 313b is the slit 313a. At both ends of the slit (313a) with a larger diameter than the width can be called a recessed hole formed in a circular shape.

The slit 313a serves to disperse stress and fatigue according to the external force concentrated on the fastener F as wide as the extended length and volume of the slit 313a, and provides a larger area than a simple hole. It is possible to increase the dispersion force against the above-described stress.

The sub-hole 313b has a function of not only strengthening the durability of the base plate 310 on which the slit 313a is formed, but also adding an effective stress dispersing force.

Specifically, when both ends of the slit 313a are thinly and long, they may be torn or stretched unnecessarily by an external force, thereby damaging the overall durability of the drum shaft assembly 300 as well as the base plate 310, which is larger than the slit 313a. By disposing the diameter sub-holes 220 at both ends of the slit 210, the above-described problem can be solved.

In addition, when the external force on the base plate 310 continues, the sub-hole 220 efficiently distributes the stress concentrated at the end of the slit 313a by the external force to solve the stress aggregation phenomenon that may be added to the slit 313a. It can serve as a function of additionally dissipating stress.

Furthermore, when the external force is not large, the occlusal force can be sufficiently dispersed with only the slit 313a as described above. Concentrated at both ends, the fatigue level of the area increases, and there may be a risk of fracture from the area, but since the above-described sub-hole 313b can efficiently disperse the stress concentrated on both ends of the slit 313a, use it for a longer period of time. It is also possible to provide a basis for ensuring the stability of the base plate 310 so that fatigue is not relatively increased.

Additionally, the sub-hole 313a has a structure such as a truncated cone that is tapered so that the diameter increases as it extends from the outer portion, which is the introduction portion, to the inner portion, which is the end portion, that is, the outer light inner narrow structure. it is possible

In this structure, the diameter of the inner portion is relatively larger than the diameter of the outer portion in order to secure a physical area capable of accommodating the concentrated or residual stress in the inner portion of the sub-hole 313b.

In addition, the external diameter of the sub-hole 313b is unnecessarily large, thereby preventing the problem of rather cracking, and securing sufficient internal space to efficiently reduce the stress of the surrounding area inside the sub-hole 313b. It can be accommodated and then provide a basis for distributed processing.

7 is an exploded perspective view showing a second modified embodiment of the drum to which a buffer plate is added.

As can be seen from Figure 7, the drum 100 of the present invention is to further dispose the buffer plate 400 between the base 200 and the drum shaft assembly 300 (specifically, the base plate 310). possible.

The buffer plate 400 is a plurality of third fastening at positions corresponding to the first and second fastening grooves 210 and 311 at regular intervals along the circumference of the buffer plate 400 in a state having a diameter corresponding to the base plate 310 . The groove 410 has a disc structure formed through it.

That is, the fastener F coupled to the first and second fastening grooves 210 and 311 passes through the second fastening groove 311 of the base plate 310 and the third fastening groove 410 and finally the base 200 . It is coupled to the first fastening groove 210 of the base plate 310 , the buffer plate 400 , and the base 200 may be mutually bound.

In addition, the buffer plate 400 is based on being made of an elastic material. At this time, the elastic material may be made of rubber, TPU, engineering plastic having elastic force such as PC, or a mixture thereof, and the buffer plate 400 is a kind of packing between the base plate 310 and the base 200 . It serves to prevent unnecessary binding of the base plate 310 and the base 200 or the occurrence of a sliding phenomenon on the coupling surface by acting as a buffer.

Furthermore, referring back to FIG. 7 , it is possible for the compression part 411 to be laminated on the inner circumferential surface of the third fastening groove 410 of the buffer plate 400 . At this time, the diameter of the third fastening groove 410 is formed to be larger than the diameter of the first and second fastening grooves 210 and 311 by the thickness of the compressing part 411, and the third fastening groove 410 is formed by the existence of the compressing part 411. to prevent the problem that the fastener (F) is not smoothly coupled due to the small diameter of the .

The compression part 411 contains graphite as an active ingredient, and when a known oil such as a lubricant is sprayed or supplied into the third fastening groove 410 before the fastener F is coupled, the compression part 411 is provided. While adsorbing this oil, when the fastener (F) is inserted into the third fastening groove 410 and applying pressure to the third fastening groove 410, the oil is discharged with this pressure to serve as a solid lubricant. In addition to preventing the fastener (F) from being unnecessarily bound to the third fastening groove (410), it also serves to absorb some of the pressure generated when the fastener (F) is coupled.
As described so far, the configuration and operation of the waste treatment apparatus having a drum for a conveyor belt with enhanced maintenance convenience according to the present invention is expressed in the above description and drawings, but this is only an example and the spirit of the present invention It is not limited to the above description and drawings, and various changes and modifications are possible without departing from the technical spirit of the present invention.
