The solidified trash 8 inserted under pressure is easily removed from the chucking sockets 17 by drawing apart both chucking sockets 7 at the time of the completion of transport.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for transferring solidified waste in pneumatic transportation equipment that transports solidified waste by air force within a transport pipe.

[Conventional technology]

Urban Tomi can be solidified by compressing and heating it in a known device as illustrated in FIG. 17 using the plastic components it contains. In Fig. 17, 1 is a hopper that receives garbage, 2 is a plate that pushes out garbage, and 3 is a hopper that receives garbage.
is a hydraulic cylinder that reciprocates the plate 2, 4Fi
5 is a conical garbage compression unit, 6 is a heating device, 7 is a cutter for cutting the extruded garbage, and 8 is a cylindrical solidified garbage. .

In this device, the hydraulic cylinder 3 is operated to move the cylinder 2t to the right in the figure, and the waste 4 is compressed in the waste compression section 5, and the waste 4 is heated from the outside by the heating device ff16. Plastic components contained therein are melted and then cut with a cutter 7 to produce solidified waste 8.

Conventionally, when the solidified waste 8 is pneumatically transported within a transport pipe, the following method has been adopted.

That is, as shown in FIG. 18, a hole is made in the center of one solidified waste 8, a connecting rod 9e is passed through this hole, a cart 10 with wheels is installed at both ends, and a shaft retainer 11 is tightened with a nut. 1
Attach it in step 2 and transport it pneumatically within the transport pipe.

As shown in Figure 1, a hole 13 is made in the center of the solidified waste 8, and a screw-like protrusion 14 is inserted into the solidified waste 8 to fix it to a cart 10 with wheels, and pneumatically transport it inside the transport pipe.

9. As shown in Figure 20, 7 tsuku 1 is added to 8 garbage assimilates.
5 and connect it to the ring 1 of the cart 16 with wheels.
The solidified material is attached to the 8fIr truck 16 using a 71C hanging trap, and is pneumatically transported within the transport pipe.

[Problem to be solved by the invention]

In the conventional method shown in FIG. 18, there are steps such as opening a hole in the center of the solidified waste 8, passing the connecting rod 9 through it, and assembling and disassembling the connecting rod 9 and the trolley 10. The next problem is that it is difficult to automate. In addition, the length of the solidified waste 8 and the hole in the center cannot be formed accurately, and the gap between the solidified waste 8 and the hole in the connecting rod 9 becomes large. There was a problem in that it collided with the inner surface and rattled when the connecting rod 9 was rotated, causing it to crack and fall apart, making it impossible to transport.

The conventional method shown in FIG. 19 was devised to solve the problems of the method shown in FIG. 18, but like the method shown in FIG. In addition to requiring hole drilling, the problem of the solidified dust 8 being cracked by the force of the screw-shaped protrusion 14 frequently occurred. As can be seen in FIG. 17, the solidified garbage 8 has a strong outer surface that has been compressed and heated, but the center is relatively soft and is supported by the trolley 1 (l) by the force of the screw-like protrusion 14. I met six problems that were difficult to solve.

In the method shown in FIG. 20 above, the hook 1 is attached to the solidified material 8.
Please note that there are 6 drawbacks that it is difficult to install 5.
In the primary transport pipe, after passing through a curved part, the transferred material is sent while causing a rotational movement (rotation movement), but if the object is turned upside down due to this rotation movement, the trapped waste solidifies. There was a problem that the object 8 would come off the ring 17. In addition, although the best option is to incinerate the waste after transport, it is also necessary to remove the 7tsuku 15 before incineration.

The present invention aims to solve the above-mentioned problems in the conventional pneumatic transportation of solidified waste.

(Next Means for Solving the Problems) ``The present invention provides a pneumatic transport facility for transporting solidified waste by air force within a transport pipe, in which one end is opened and the other end is closed, and the above-mentioned opening is performed and the next end is closed. A pair of chucking sockets each having a conical taper portion on the inner surface that decreases from one end toward the other end are arranged with the open ends facing each other at a distance, and the conical shape of the pair of chucking sockets is This invention relates to a transfer device for solidified waste that is compressed to hold the solidified waste using a tapered portion.

(2) In the invention as set forth in (1) above, the non-assimilated waste storage section is provided which is connected to the inner part of the conical taper section in the chucking socket and has an opening that passes through the chucking socket.

A convex taper portion aligned with the concave taper portion was provided on the opposite side of the open end of the other chucking socket.

(5) In the above invention (1), the pair of chucking sockets are connected by a telescopic connecting member having a spring.

[Effect]

In the present invention as described in (1) above, by press-fitting the outer peripheries of both ends of the solidified waste into the opposing conical tapered parts of the pair of chucking sockets, the solidified waste is held by the pair of chucking sockets. be done.

Moreover, since the outer periphery of the solidified waste is strongly solidified as described above, the solidified waste is reliably held by the conical taper part of the chucking socket and is prevented from being destroyed during transportation. can be avoided. The press-fitted solidified waste can be easily removed from the chucking socket by pulling both chucking sockets apart at the end of transportation.

In addition, when pneumatic transportation is performed by a pressure-feeding method, a force acts on the solidified waste in the direction of press-fitting, and the conical taper portion securely holds the solidified waste.

In the present invention described in (2) above, the effect of the invention described in (1) above (in addition, garbage that is difficult to solidify, such as bottles, cans, earth and sand, and rubble, is stored in the chucking socket as non-solidified garbage). The waste will be stored in the department and transported along with the waste assimilate.

<3), (In the present invention of 41, the above (1)
(In addition, the outer tapered portion of the other chucking socket is engaged with the conical tapered portion of one chucking socket, or the concave and convex tapered portions of the pair of chucking sockets are press-fitted into engagement. By matching and separating, the pair of chucking sockets can be fixed to each other.Thus, both of the chucking sockets are firmly fixed, making it easy to return the solidified waste to the transport pipe after transporting it.

(9) According to the present invention (5) above, in addition to the action of the invention (1) above, by the spring force of the connecting member,
To reliably hold solidified waste in a chucking socket even when a transport pipe has many curved parts. In particular, in the case of suction type pneumatic transportation, a pulling force is applied when the chucking socket is busy, but the spring force is applied to this button, so that the solidified waste is reliably supported and transferred by the chucking socket. .
