Description

Automatic pressure relief glass furnace crack repair device

Technical field

The invention relates to an automatic pressure relief device for repairing cracks in a glass furnace.

Background technique

The glass furnace is a kind of melting device that the glass manufacturing industry must have. The raw materials of glass products need to be melted in the glass furnace to form the glass products.

However, during the use of the glass furnace, the furnace wall and the cover will have cracks. At present, the refractory repair agent is usually applied to the cracks for repair. However, due to the high temperature of the glass furnace, conventional repairs such as painting are used. In this way, the refractory repairing agent will solidify when it touches the cracks. As a result, the refractory repairing agent can only repair the surface of the crack and cannot repair the deep part of the crack. Therefore, its repair effect is poor and it is easy to crack again.

technical problem

In view of the above-mentioned problems, the present invention provides a device for repairing cracks in a glass furnace with automatic pressure relief, thereby effectively solving the problems pointed out in the background art.

Technical solutions

The technical solution adopted by the present invention is: an automatic pressure relief device for repairing cracks in a glass furnace, which includes a storage bin with a foot at the bottom, a discharging pipe at the middle bottom of the bin, and the discharging pipe The outer end of the pipe is connected with a flexible feeding pipe, the feeding pipe is provided with a feeding valve, the front end of the flexible feeding pipe is connected with a feeding steel pipe, and the rear of the feeding pipe is provided with feeding The front end of the injection steel pipe is a flat discharge port, the top of the storage bin is provided with a feeding pipe, the feeding pipe is provided with a feeding valve, and the top of the storage bin is provided with an air inlet pipe and An exhaust pipe, an intake valve is arranged on the intake pipe, and a pressure relief valve is arranged on the exhaust pipe.

Preferably, the outer end of the feeding tube is provided with a funnel-shaped feeding port.

When the repair material in the storage bin is insufficient, it can be replenished by opening the feeding valve. The feed inlet adopts a funnel-shaped structure to facilitate the quick pour of the repair material.

Preferably, a pressure gauge for monitoring the internal air pressure of the storage bin is installed outside the storage bin.

The pressure in the storage bin is monitored in real time by a pressure gauge, and the pressure in the storage bin should be maintained at 3-5kg.

Preferably, when the air pressure in the storage bin is higher than 5 kg, the pressure relief valve is automatically opened for exhaust.

The pressure relief valve automatically exhausts when the pressure in the storage bin is too high to prevent safety accidents, especially when the operator closes the injection valve after the repair is completed, the air pressure in the storage bin increases significantly due to continuous air intake , The pressure can be automatically relieved through the pressure relief valve.

Preferably, the injection steel pipe is provided with a holding part behind the injection valve.

When repairing cracks, the operator can hold the grip to operate.

Preferably, the holding part is made of heat-insulating silica gel.

Since the injection steel pipe is an iron product, its thermal conductivity is good, and the heat-insulating silica gel can prevent the grip from being overheated and unable to operate.

Preferably, the flexible unloading pipeline is a rubber tube.

Beneficial effect

The invention can send the repairing material in the storage bin to the depth of the crack, thereby improving the repairing effect, and the flat discharge port at the front end of the injection steel pipe can penetrate into the crack, thereby further improving the effect of injecting the repairing material into the depth of the crack.

Description of the drawings

Figure 1 is a schematic diagram of the structure of the present invention.

The best mode of the present invention

The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

As shown in Figure 1, an automatic pressure relief device for repairing cracks in a glass furnace includes a storage bin 1 with feet 2 at the bottom, and a discharge pipe 3 at the middle bottom of the storage bin 1. The outer end of the feed pipe 3 is connected with a flexible feeding pipe 4, the feeding pipe 3 is provided with a feeding valve 4, and the front end of the flexible feeding pipe 4 is connected with a feeding steel pipe 5. The rear part of the steel pipe 5 is provided with an injection valve 6, the front end of the injection steel pipe 5 is a flat discharge port 7, and the top of the storage bin 1 is provided with a feeding pipe 8, and the feeding pipe 8 is provided with Feeding valve 9, the top of the storage bin 1 is provided with an intake pipe 10 and an exhaust pipe 11, the intake pipe 10 is provided with an intake valve 12, and the exhaust pipe 11 is provided with a pressure relief valve 13.

The outer end of the intake pipe 10 is connected with high-pressure gas.

The outer end of the feeding tube 8 is provided with a funnel-shaped feeding port 14.

A pressure gauge 15 for monitoring the internal air pressure of the storage bin 1 is installed outside the storage bin 1.

When the air pressure in the storage bin 1 is higher than 5 kg, the pressure relief valve 13 is automatically opened for exhaust.

The injection steel pipe 5 is provided with a holding part 16 behind the injection valve 6.

The working principle of the present invention: open the feeding valve 9, pour the mixed repair material from the feed port 14 into the storage bin 1, and the poured amount does not exceed 1/2 of the capacity of the storage bin 1, then close the charging valve 9 , Open the feeding valve 4 and the inlet valve 12, and pass the high pressure gas of 3-5kg pressure into the storage bin 1 through the inlet pipe 10. The repair material in the storage bin 1 is discharged from the feeding pipe under the action of the high pressure gas 3 discharge. During the repair operation, the operator holds the grip 16, and then aligns the flat discharge port 7 at the front end of the injection steel pipe 5 to the crack and penetrates into the depth of the crack. Finally, open the injection valve 6 to be able to Inject the repair material into the cracks to complete the repair of the cracks. After one crack is repaired, the injection valve 6 can be closed, the flat discharge port 7 can be moved to another crack, and then the injection valve 6 can be opened for another Repair of a crack.

When the injection valve 6 is closed, due to the design of the pressure relief valve 13, the pressure in the storage bin 1 is kept below 5kg, thereby preventing excessive pressure in the storage bin 1 from damaging the storage bin 1 and even causing safety accidents .
