Description

Waste warhead treatment device of inert coal {APPARATUS FOR MECHANICALLY PROCESSING WASTE WARHEAD OF INACTIVE BOMB}

The present invention is directed to a device for cutting off waste warheads of inert coal.

At present, the Korean military collects and treats shells (hereinafter referred to as "inactive carbon" or simply "coal") that have reached the sea during the shell development test and acceptance test.

Among the coals collected in this way, high-bombs or unidentifiable coals are commissioned by the explosive disposal unit (EOD), and inert coals are stored in the storage.

In the case of unexploded bombs, for example, 6.25 pounds (2.835 kg) of explosives are installed above and below the coal body, and then the explosives are detonated by a fire wire at a sufficient distance away from the evacuation site to disable the bombs. have.

Typically, when detonating bombs, the evacuation site should be selected for concealment or cover to protect personnel from debris and flames, taking into account the safety and viability of explosives handling personnel.

However, detonation and storage of inert coal have the following problems.

First of all, in the case of treatment of unexploded coal, there is a inconvenience in that a thorough preparation is necessary in advance, such as installing an ignition device in duplicate in case of explosives unexplained.

In addition, even if the explosives are exploded with inert coal, the coal fragments are not completely decomposed but the fragments of the coal fragments remain. Therefore, there is a problem that the fragments of carbon are collected and disposed of.

In addition, for safety reasons, because the coal is handled only in the controlled place, there is a disadvantage that the coal must be transported from the collecting place to the controlled place. This will incur shipping and labor costs.

Therefore, considering both the cost of the explosives installation and the cost of collecting and separately processing the debris generated during the detonation process, it takes a considerable cost to process one shot.

In addition to this, there is an absolute shortage of places where bombs can be detonated, and the amount of treatment continues to accumulate.

For this reason, it is also required to expand the storage for temporarily storing the bullets which could not be processed immediately, but it is very difficult to add a new detonation place or to add more storage.

In addition, environmental pollution due to residues generated during bomb detonation is also concerned, and it is difficult to train and retain professional manpower.

In addition, since the generation of inert coal is increasing year by year, the above-mentioned problems are getting worse and there is no sign of solving them.

Therefore, it is urgent to construct a new treatment method and treatment system that can treat inert coal environmentally, safely and economically.

On the other hand, the inventors have searched for domestic patents / utility models, and as such, the apparatus for mechanically cutting waste warheads of inert coal has not been proposed until now. However, Patent Literature 1 is known in connection with the warhead fixation required when the waste warhead of the inert coal is cut.

Korean Utility Model Publication No. 1998-63658

The object of the present invention is to propose a waste warhead treatment apparatus and a series of treatment processes of inert coal, which can cut / disassemble in an environmentally friendly way instead of detonating inert carbon so that a portion of the coal can be recycled. have.

The present inventors have considered that in consideration of safety, efficiency, environmental impact, etc. in the disposal process of inert carbon, it is preferable to cut and decompose two or more pieces rather than detonating the inert carbon.

In general, inert carbon has different parts and complex structures, so in order to safely cut the inert carbon into two or more pieces, an understanding of the characteristics of the warhead must be preceded.

Here, for the sake of convenience, it is assumed that all the inert coals to be treated are divided into two parts. For example, one of the two parts is the latter part of the inert coal (inactive fuse part), which is composed of aluminum, which is weighted only to replace a mechanical or electrical active fuse.

On the other hand, the other of the two parts is the first half (warhead) of the inert carbon, which is a part in which gypsum is filled in the body.

Next, as a technique for cutting waste warheads of inert carbon, the inventors first considered, laser cutting (oxygen arc cutting), plasma cutting using high heat ( plasma arc cutting) and water-jet cutting techniques.

However, these techniques are inferior in economy and workability to the cutting technique using the lathe proposed in the present invention, and finally, the present inventors adopted the cutting technique using the lathe.

Although it will be more clearly understood from the description of the embodiments based on the accompanying drawings, the present inventors propose that the cutting process of the waste warhead of the inert coal proposed by the present invention by the treatment apparatus partially remodeling a general lathe (1) → The operation is performed in the order of (4).

(1) Fix the shot to the chuck and center rest of the treatment unit using handling equipment.

(2) The maximum feed amount of the cutting tool mounted on the tool post of the processing unit is controlled by the limit switch.

(3) Supply of cutting oil and cutting of warheads.

(4) After the cutting of the warhead, use the handling equipment to remove the bullet into two parts from the treatment unit.

Here, as the cutting bite used for cutting the closed warhead, in consideration of the material and the cutting resistance of the warhead, it is preferable to use the cutting bite as high as possible.

In practice, spent coal (i.e., shots taken after firing) was harder than unused ones and used carbide bites because it was not easy to cut warheads even with high-speed steel bites.

This increase in hardness is considered to be because the warhead heated by the heat (2000 to 4000 K) generated in the shell steel when the shell is fired hardens while being stuck to the cold sea water.

In connection with the configuration of the treatment apparatus, the waste warhead treatment apparatus for inert coal according to the present invention, the headstock is disposed at one end of the bed, the tailstock is disposed at the other end of the bed, it is possible to transfer between the headstock and the tailstock A part of a general-purpose lathe in which a tool post is disposed on the bed so as to be partially modified. A dustproof port that can slide along the bed and is fixed to an arbitrary point on the bed is provided in the bed between the main shaft and the tailstock. The spheres are arranged at equiangular intervals along the circumference of the closed warhead inserted into the inner space of the dustproof outlet, and a plurality of pneumatic cylinders in which the piston rod is spouted toward the closed warhead, and the closed warhead inserted into the inner space of the dustproof opening. And a support roller provided at the distal end of the piston rod of each pneumatic cylinder so as to be rotatably supported. The chuck provided in the chuck is equipped with three jaws machined in the same or similar shape as the rear shape of the closed warhead at 120 ° intervals, and the tool post allows the tool carriage equipped with the cutting bite to move forward and backward toward the closed warhead. It characterized in that it comprises a pneumatic cylinder, and a limit switch or sensor provided at one point of the tool post or bed in the direction in which the tool carrier is advanced.

As mentioned above, the present invention utilizes a treatment device that is partially adapted to a general-purpose lathe instead of detonating inert coal recovered after shooting, thereby cutting waste warheads of inert coal in an environmentally friendly manner. It is aimed at making it possible to recycle some parts, such as coal bodies.

One of the reasons for dismantling the inert charcoal into two parts is to recycle the charcoal and the inert fuse part of economic value after removing the gypsum, sand, paraffin and the like filled in the shell of the waste warhead.

To this end, there is a need for a treatment device of the present invention in which the general-purpose shelf is partially remodeled and a handling device that facilitates handling of inert coal.

Here, examples of the handling equipment include a jib crane provided with a vise capable of catching and lifting the inert coal and a pneumatic mechanism such as a compressor.

In the case of the 155 mm K 307 bullet, the length from the tail to the tip of the bullet is about 65 cm, the weight is about 45 kg, and is generally streamlined.

For this reason, when the rear end of a bullet is grasped and rotated using the short length jaw provided by the plurality of chucks of a general-purpose lathe as it is, slipping will arise between them.

So, in the processing apparatus which concerns on one Embodiment of this invention, as shown in FIG.3 (a), length of the jaw 30 with which the chuck is provided is made larger than the length of the jaw provided with the general purpose shelf, The tail of S) can be firmly gripped.

1, 2, and 3 (b), the center axis of the bullet S is aligned on an imaginary axis connecting the center of the chuck 20 and the tail stock 50. A dustproof opening 40 rotatably supporting the first half of the shot S was installed on the bed 90 between the chuck 20 and the tail stock 50.

In addition, in one embodiment of the present invention, a carbide bite was used to easily cut the coal S having a hard surface. According to the experiments of the present inventors, a 25 mm thick carcass was able to be cut within 15 minutes. .

Hereinafter, an apparatus for treating waste warhead of inactive carbon according to one embodiment of the present invention is described in detail based on the accompanying drawings.

First, as shown in FIGS. 1-3, the waste warhead processing apparatus of the inert carbon of this embodiment is comprised with the structure similar to the general purpose shelf. That is, like the general-purpose lathe, the headstock 10, the chuck 20, the tail stock 50, and the tool rack 60 are disposed on the bed 90.

Moreover, the cutting oil supply pipe 70 is arrange | positioned near the tool stand 60 so that cutting oil which is a coolant can be supplied to the site | part cut by a cemented carbide bite at the time of cutting | disconnection of the shot S.

The headstock 10 is driven by a 5-horsepower motor so that even when the heavy bullet S is set on the chuck 20, it can be smoothly rotated.

The tool post 60 is comprised so that 1 stroke operation may be performed automatically by a pneumatic cylinder rather than manual. For example, the tool carriage 60 is mounted on the tool carriage 60 so as to be able to move forward and backward in the cutting bite feeding direction (the direction in which the piston rod of the pneumatic cylinder is drawn out). In addition, a limit switch or a sensor is provided at one point in the direction in which the tool carriage moves in. When the tool carriage reaches the position where the limit switch or the like is installed, the tool carriage is retracted to the initial position or the headstock 10 It stops the rotation of all the work is configured to complete.

The chuck 20 is processed into the same or similar shape as the tail shape of the bullet S so that the bullet S can be smoothly mounted. In addition, three chucks 30 having a holding length (or area) more than twice larger than conventional general-purpose lathes are mounted at 120 ° intervals so that the tail of the shot can be gripped firmly. have.

Moreover, on the bed 90 between the headstock 10 and the tool stand 60, the dustproof opening 40 in which three pneumatic cylinders 41 are arrange | positioned at 120 degree space | interval is provided. Although shown also in FIG.3 (b), in each pneumatic cylinder 41, the support roller 42 is rotatably attached to the front-end | tip of a piston rod. In addition, the dustproof opening is, for example, a butterfly bolt along the lengthwise direction of the bed, i.e. when the slide is reached at an appropriate position while sliding on the bed 90 between the headstock 10 and the tool rest 60. By using a conventional fastening means such as, it is configured to be fixed to the position.

The process of cutting a waste warhead with the waste warhead processing apparatus of the inert carbon of this embodiment comprised as mentioned above is as follows.

First, as illustrated in FIG. 2, a single coal S is picked up by a handling equipment (eg, a crane) equipped with a vise 80 and transferred to an upper portion of a waste warhead treatment device of inactive coal, and then a coal S is used. ) Is lowered so that the center axis of the bullet (S) is aligned on an imaginary axis connecting the center of the chuck 20 and the tail stock 50.

Thereafter, the rear end of the bullet is positioned between the three jaws 30 provided in the chuck, and the three jaws 30 are closed again to firmly grip the tail of the bullet.

Subsequently, the ring-shaped dustproof opening 40 is moved on the bed 90 so that the tip portion of the bullet S passes through the inner space of the dustproof opening 40, as shown in FIG.

In this way, in the state in which the tip portion of the bullet S passes through the inner space of the dustproof port, the pneumatic cylinder 41 provided in the dustproof port is operated individually or simultaneously, and the support mounted on the piston rod of the pneumatic cylinder is supported. The rollers 42 support the front ends of the shots.

Then, as in the general-purpose lathe, the position of the tool post 60 on which the cutting bite is mounted is adjusted. At this time, the position of the limit switch, which determines the maximum feed amount of the cutting bite, can also be adjusted, such that the position adjustment of the limit switch may be performed by removing the limit switch from one point and attaching it to another point, for example, by moving and positioning the limit switch. This can be achieved by installing a limit switch on a block that can be fixed.

When the above settings are completed, the cutting operation is started through the cutting oil supply pipe 70 while supplying cutting oil to the cutting position of the shot S, for example, the boundary between the inactive fuse portion and the warhead.

Then, in the course of the cutting operation, if the limit switch is operated, all the work is finished.

When all the work is completed, as shown in Fig. 4, after confirming that the coal is completely separated into two parts, the non-cutting warhead processing apparatus of the inert coal of the present embodiment is cut into two parts by using the handling equipment. Remove activated carbon.

Here, the waste warhead treatment apparatus for inert coal according to the present invention is, for safety reasons, even if a barrier is installed between the waste warhead treatment apparatus for inert coal and an operator, the operator across the barrier is a control unit. By using, it is preferable to be configured to control the power supply or the rotational drive of the main shaft. For example, if a wire is connected between each part of an inert coal waste warhead treatment device and a button or a switch placed in a control unit for controlling these parts, an operator may be able to push the button or switch even across the firewall. It is possible to control each part of the waste warhead treatment apparatus of inert coal by operating.

In addition, in the case of cutting the shot, in order to ensure smooth work and safety, all clamping and connecting parts and tightening state of the cutting bite must be checked, and the coolant supply must also be checked.

In addition, the setting of the maximum feed amount of the cutting bite made through adjustment of a limit switch should be made in consideration of the thickness of a cutting part.

The coal divided into two parts through the above process is introduced into the melting facility and melted, for example, the filling material such as gypsum is removed from the coal body, and the melt discharged from the melting facility is solidified and disposed of in an ingot form for handling. .
