Description

[0001] A DUST COLLECTOR FOR DIE CASTING [0002]

The present invention relates to a dust collecting apparatus for diecasting, and more particularly, to a dust collecting apparatus for diecasting which is used to prevent molds and castings from sticking to each other during diecasting, and which can easily collect and remove dust, Quot;

In general, die casting casting is a method of injecting molten metal into a mold at a predetermined pressure and solidifying the molten metal in a mold to obtain a product in a desired shape, and aluminum alloy or zinc alloy material having a relatively low melting temperature is used In addition, it is possible to mass-produce a high-precision, thin-walled product and to reduce the processing cost, thus being used in various industrial fields.

In the process of producing a product using die casting as described above, the oxidation scale generated on the inner surface of the mold is removed, and water, a release agent, and an anti-squeezing agent are injected into the mold by the injection device .

In the case of not collecting the releasing agent as described above, the scattered release agent may be restored to the inside of the mold or may be stuck on the peripheral device or article to cause contamination as well as malfunctions. Therefore, .

Conventionally, a large number of dust collecting devices have been developed and used for this purpose. A typical example of the dust collecting device is shown in FIG. 5, which is a technical structure of Patent No. 0863093.

A dust collecting apparatus 1 for a die casting to which the prior art is applied is provided with an injector 10 for injecting a detergent into a mold 2 and an injector 10 disposed above the mold 2, An upper exhaust hood 20 for sucking the noxious gas upward and discharging the noxious gas upward and for discharging the noxious gas upward; And a lower exhaust hood for discharging noxious gas moved downward along the air guide (32) after being vaporized on the surface of the mold (2) and positioned to face the air supplier (30) (40).

The injector 10 includes a plurality of injection nozzles 12 for spraying water, a release agent, and an anti-fouling agent toward the mold 2. The air feeder 30 is disposed above the mold 2, Respectively. The air feeder 30 may include an air tube formed along the left and right sides of the mold 2 and an air nozzle provided in the air tube and configured to inject air.

A plurality of air nozzles are disposed at predetermined intervals in the longitudinal direction of the air tube and are disposed downward from a lower portion of the air tube so as to inject air downward, (4).

The lower exhaust hood 40 is installed on the base 6 of the high-pressure casting machine and is disposed on the upper left and right sides of the base 6, And a lower exhaust pipe portion 44 connected to the lower hood portion 42 and installed inside the base 6. [

Patent Application No. 10-1997 -0023969 Patent No. 10-0863093-0000 Patent No. 10-1111093-0000

The above-described prior art dust collecting apparatus for diecasting collects the release agent discharged from the mold through the upper exhaust hood and the lower exhaust hood installed at the upper and lower portions of the mold, and then discharges them to the outside.

In this prior art, since the mold release agent scattered from the mold is simply sucked from the upper and lower sides of the mold by the suction means and then the collected mold release agent is separated again, the entire equipment is increased and the installation cost is accordingly increased In addition, it takes a lot of time and money to operate and maintain it.

Since the mold release agent scattered from the high-temperature mold is in a high temperature state, when it is simply sucked, it causes damage to the internal parts of the dust collecting apparatus such as suction means and piping in the process of sucking, Despite the fact that the release agent should be collected quickly when needed, it is often impossible to keep the inside of the workplace in a constant state due to the inability to do so.

Since the releasing agent is not only in a high temperature state but also in a state where a large amount of moisture is contained in the releasing agent, it is adsorbed to the inside of the apparatus during the suction and collecting thereof, thereby causing scale generation, It also serves as another problem.

In addition, since the release agent that is scattered is collected, and the moisture and the release agent are separated through a separate device, only the air is released to the atmosphere. However, since a large amount of release agent is contained in the air, .

First of all, since the mold release agent is sucked around the mold, the release agent sucked by the suction means, and the separate separator for separating the moisture and the like from the pure air must be installed separately. Therefore, It is the fact that there are many problems such as the rise, the efficient and the immediate dust collecting is impossible.

In order to solve the above-mentioned problems, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a vacuum cleaner having a hexahedral equipment body, a suction unit installed at a central position of the apparatus body for sucking a release agent to be removed, And a quadratic overhang which separates the release agent separated from the moisture from the air and discharges pure air to the atmosphere.

It is possible to reduce the cost and time required for installation and maintenance by minimizing the volume, and it is possible to efficiently remove the release agent to improve the dust collecting efficiency and to maintain a pleasant indoor environment.

The present invention can reduce the size of the dust collecting device and separate the release agent scattered from the mold quickly and cleanly and separate it into moisture, a releasing agent and pure air to release only pure air, It is possible to maintain a pleasant working environment by maximizing the efficiency, and to provide a high-quality dust collecting device to enhance external competitiveness.

The motor room 118 may be provided with a motor room 118 and a plate-like sound insulation silencer S may be installed to reduce noises generated during the operation of the motor 119 by the motor room 118 and the supporter It will be acceptable.

The inner end of the suction pipe 111 forms a concentrated portion 120 whose diameter is reduced so as to concentrate and supply the sucked release agent to the center of the suction fan 117, (117) to be separated from the mold release agent and water.

The lower end of the suction chamber 116 is formed by a centrifugal separator and a discharge hopper 121 having a narrow upper portion and a wide lower portion so that water can be sent to the upper portion 130.

The primary filtration unit 130 is provided with a primary filtration filter 131 for filtering and filtering the releasing agent centrifugally discharged at the lower part of the discharge hopper 121. The primary filtration filter 131 Is held by a filter support 132 such as a supporter or a sump and the lower end of the discharge hopper 121 and the upper part of the primary filtration filter 131 are maintained in a coupled state so that air, And is allowed to fall downward through the primary filter 131 via the filter 131.

It is preferable that the primary filter 131 is spaced apart from the device body 105 by the filter support 132 so as to form a passageway 133 through which the filtered air can move upward will be.

The passageway 133 may be formed on both sides of the apparatus body 105 or two front and rear side portions. However, the passageway 133 may be spaced apart from the apparatus body 105 to allow smooth movement.

A drain hole 135 is formed in one of the water collecting chamber 134 formed naturally below the primary filtering filter 131 so as to discharge the collected water to the outside, And a lower door 136 capable of exchanging the primary filtration filter 131 is provided on the side of the lower surface of the casing.

The secondary filling section 150 includes a secondary filtration filter 151 for primarily filtering the release agent contained in the air that is primarily filtered at the upper side of the apparatus body 105 and moving upwards to release only pure air to the atmosphere, .

The secondary filter 151 may use various types of filters, but it may be made of a HEPA filter (High Efficiency Particulate Air Filter) or a HEPA filter (ULPA Filter, Ultra-Low Penetration Air Filter) is preferably used.

The secondary filtration filter 151 can be held on the upper part of the device body 105 by the filter holding means 152 and pure air completely removed by the secondary filtration filter 151 can be held by the device body 105 So that it can be discharged into the atmosphere through the discharge port 153 installed at the upper part.

A collecting guide 155 is mounted on the lower side of the secondary filtration filter 151 so as to collect the air that is lifted upward from the primary lowering part 130 by the secondary filtration filter 151 and a secondary filtration filter 151 A discharge guide 156 for guiding pure air having passed through the secondary filtration filter 151 to the discharge port 153 is mounted.

An upper door 160 for exchanging the secondary filter 151 is installed on one side of the apparatus body 105 on which the secondary filter 151 is installed.

The use state of the dust collecting apparatus 100 according to the present invention is as follows.

When the dust collecting apparatus 100 for diecasting is brought close to the die casters and the suction tube 111 is operated in a state where the suction tube 111 is placed at a position where the release agent is dispersed from the mold, the release agent scattered from the mold is sucked Is introduced into the suction chamber (116) through the suction pipe (111) by the suction force of the fan (117).

In this process, foreign particles of large particles which are impregnated with the release agent are firstly removed by the sieve 112 installed in the suction pipe 111, and the temperature is detected by the temperature sensor 113 installed in the suction pipe 111 in real time It is applied to the controller, and when the temperature is higher than the set temperature, it is temporarily stopped or stopped to prevent the entire apparatus from causing an abnormality.

Further, noise generated during the operation of the motor 119 by the sound-insulating silencer S, which is further provided to the outside of the motor chamber 118, is reduced, so that the surroundings of the dust collecting apparatus 100 can be maintained in a pleasant state .

The release agent introduced into the suction chamber 116 is discharged through the discharge hopper 121 to the lower primary discharge section 130 in a state of being centrifuged with the release agent and moisture by the suction fan 117 rotating at high speed.

In a state of being moved to the primary charging section 130, the primary agent is passed through the primary filtration filter 131 installed below the discharge hopper 121, the primary agent is filtered, and the moisture and air are introduced into the primary filtration filter 131 And water is discharged to the outside through the drain hole 135 in a state where the water is collected in the water collecting chamber 134.

The air that has passed through the primary filtration filter 131 and a part of the releasing agent are sucked by the suction force of the suction fan 117 through the passage 133 formed between the primary filtration filter 131 and the apparatus body 105, And moves to the upper side of the body 105.

The air and the part of the releasing agent that have moved upward pass through the primary filtration filter 151 provided below the discharge port 153 to separate the release agent and some foreign substances and only pure air is discharged to the atmosphere through the discharge port 153 .

Particularly, in the case of the secondary filtration filter 151, a HEPA filter (High Efficiency Particulate Air Filter) for filtering particulates or an ULPA Filter (Ultra-Low Penetration Air Filter) is used, so that the mold release agent and the foreign matter can be completely filtered out.

Of course, when the first and second filter filters 131 and 151 are contaminated or damaged in the course of use, the lower door 136 and the upper door 160 are opened to replace the first and second filter filters 131 and 151, It would be natural to make sure that it does not hinder the removal.

When the air and the releasing agent migrate to the primary overflow section 130 and the secondary overflow section 150 through the suction chamber 116, they are moved only to the primary filtration filter 131 in the suction chamber 116 by the discharge hopper 121 And the secondary filter 151 is prevented from flowing out to another place by the collecting guide 155 provided below the secondary filter 151. The air that has passed through the secondary filter 151 It is possible to prevent the release agent and the foreign matter from leaking from the inside of the device body 105 to reduce the dust collecting efficiency by allowing the discharge guide 156 to move only to the discharge port 153 and to be discharged.

As described above, the present invention has the advantages of minimizing the volume and reducing the cost and time required for installation and maintenance, efficiently removing the mold release agent, improving the dust collecting efficiency, and maintaining a pleasant indoor environment.
