Description

[0001] The present invention relates to a mold cleaning apparatus using an inverter pump,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold cleaning apparatus using an inverter pump, and more particularly, to a mold cleaning apparatus using an inverter pump capable of effectively removing foreign substances and scales in a mold by improving the structure of the mold cleaning apparatus.

As shown in FIG. 1, a pipe cleaning apparatus using a conventional pneumatic shock wave includes a pipe 10 installed in a boiler or a heat exchanger; A supply pipe 61 connected to one end of the pipe 10 to supply a rinse solution and a number of times of connection with the other end of the pipe 10 so that the rinse solution is recovered through the supply pipe 61 and the pipe 10, A drug tank (60) having a tube (62); A supply valve (21) and a shutoff valve (62) provided between the supply pipe (61) and the return pipe (62) for controlling supply and blocking of the rinsing liquid; A pump (50) interposed between the supply pipe (61) and the chemical tank (60) to pump the cleaning liquid contained in the chemical tank (60); A compressor 50 for generating an air pressure shock wave so that the cleaning liquid pumped through the pump 50 shortly impacts the inside of the pipe 10 and the operation of the compressor 50 and the supply valve 21, And a control unit (30) for controlling the opening and closing of the door (22).

As described above, in the pipe cleaning apparatus using the conventional pneumatic shock wave, a compressor for generating air pressure is installed in the supply pipe, and compressed air is injected by the compressor, and scales and foreign substances are removed while moving along the pipe. However, since compressed air of the compressor has a constant pressure, scales and foreign substances are effectively removed at the portion to be sprayed on the inlet side of the piping, but the discharge side of the circulating piping is difficult to remove scales and foreign matter.

In order to periodically spray the compressed air with the compressor, a variety of equipments are required, which is costly.

It is to communicate the point more clearly.

2 and 3, the mold cleaning apparatus using the inverter pump of the present invention includes a mold 100, dispensers 110 and 120 connected to the mold 100, a mixing tank 130 A supply / recovery line (150, 160) installed between the mixing tank (130) and the supply / recovery side distributor (110, 120) An inverter pump 170 installed in the supply line 150, first, second and third connection pipes 180, 190 and 200 connected to the supply line 150 and the recovery line 160, A first valve 210 installed in the supply line 150 and disposed between the first and second connection pipes 180 and 190 and a second valve 230 installed in the pipe 180, A second valve 220 installed in the supply side distributor 110 and disposed between the first and second connection pipes 190 and 200 and a second valve 220 installed in the supply side distributor 110, (100) is configured toward the air injection device 250 for performing residual water removal.

The mold 100 is provided with a plurality of cooling lines 101 therein.

The supply / withdrawal side distributors 110 and 120 are connected to the supply line 150 and the withdrawal line 160, respectively. And the supply / withdrawal side distributors 110 and 120 are individually connected to the cooling line 101 of the mold 100, respectively.

The mixing tank 130 is provided with a heater 131 for heating the water filled therein to a predetermined temperature.

The medicine supply unit 140 is provided with a medicine metering pump 141 for supplying the medicine to the mixing tank 130 at a predetermined ratio.

The inverter pump 170 injects medicine at a predetermined pressure together with the water transferred from the mixing tank 130. For example, low pressure is preferably sprayed at 2 bar for 20-30 minutes, and high pressure spray at 5 bar for 2-5 minutes.

A fourth valve (240) is installed in the discharge side supply line (150) of the inverter pump (170).

A third valve 230 is installed in the first connection pipe 180 to perform a bypass function by the third valve 230.

The first and second valves 210 and 220 are normally open when the water and medicines are fed to the second connection pipe 190. The first and second valves 210 and 220 are connected to the return side distributor 120, 110 to the third connection pipe 200 side.

An air injection device 250 is installed in the supply side distributor 110 to inject compressed air forcibly through the supply side distributor 110 and the mold 100 to induce discharge of water and chemicals remaining in the mold 100. [ .
