[0045] In some embodiments, the feeding mechanism includes a feeding port 3, a feeding valve 4 and a feeding pipe 5. The feeding port is funnel-shaped, and the upper opening is arranged opposite to the raw material outlet; the feeding valve is connected to the lower opening of the feeding port; one end of the feeding pipe is connected to the feeding valve 4, and the other end is connected to the inlet of the storage tank 1.

[0047] In some embodiments, the pressure control mechanism further includes a pressure gauge 8, which is disposed on the storage tank and located at the upper end of the boost valve.

[0048] In some embodiments, the discharging mechanism includes a three-way pipe 9, a booster unit and a discharging unit, the first end of the three-way pipe is connected to the outlet of the storage tank; the booster unit is connected to the second end of the three-way pipe; and the discharging unit is connected to the third end of the three-way pipe.

[0049] In some embodiments, the boost unit includes a boost valve 10 and a boost pipe 11, the first end of the boost valve is connected to the second end of the three-way pipe; one end of the boost pipe is connected to the second end of the boost valve, and the other end is connected to an external boosting device.

[0050] In some embodiments, the discharge unit includes a discharge valve 12 and a discharge pipe 13, the first end of the discharge valve is connected to the third end of the three-way pipe; one end of the discharge pipe is connected to the second end of the discharge valve, and the other end is connected to the material conveying pipe 14.

[0051] In some embodiments, the base is supported by a tripod.

[0052] When using the injection molding device for repairing refractory materials provided in the embodiment of the present application, the first step is to select an appropriate storage tank according to the site requirements. The storage tank is selected with a volume V controlled at 1m 3 ≥V≥0.6m 3 , to ensure that the material pressed in does not exceed 1 / 3 of the tank volume;

[0053] The second step is to open an inlet on the upper part of the storage tank to connect to the feed pipe, the inlet diameter is controlled at 30cm-50cm, the wall thickness is 6mm-8mm, and a feed valve (ball valve) is provided to connect to the feed port;

[0054] The third step is to open an outlet at the bottom of the storage tank to connect to the first end of the "T" type three-way pipe. The outlet diameter is controlled at 50mm-60mm. The "T" type three-way pipe and the lower outlet of the storage tank are connected to the discharge pipe direction using seamless steel pipes. The inner diameter is controlled at 50mm-60mm, and the wall thickness is controlled at 5mm-8mm. The uniform wall thickness of the seamless steel pipe is conducive to the flow of refractory materials inside it. At the same time, the thicker wall thickness is conducive to resisting the wear of large-particle aggregates in the refractory materials, and withstand the pressure of 0.8Mpa-1.5Mpa compressed air; the boost side of the "T" type three-way pipe uses seamless steel pipes, with an inner diameter of 15mm-20mm and a wall thickness of 3mm-5mm. The air intake is controlled by a booster ball valve. The air source pressure is 0.8Mpa-1.5Mpa.

[0055] The fourth step is to install a boost valve (ball valve) on one side of the upper part of the storage tank. The boost valve is connected to the external boost equipment through a boost pipe, which can be an air compressor or a compressed air pipe on site. The boost pipe is made of seamless steel pipe with an inner diameter of 40mm-50mm and a wall thickness of 6mm-8mm. The air intake is controlled by the boost ball valve. The boost air source pressure is controlled at 0.8Mpa-1.5Mpa.

[0056] The fifth step is to connect the second end of the three-way pipe to the booster valve, which is connected to the external booster equipment through the booster pipe, which can be an air compressor or a compressed air pipeline on site. The third end of the three-way pipe is connected to the discharge valve, which is connected to the material conveying pipeline through the discharge pipeline.

[0057] When using the injection device for refractory repair to inject refractory materials, first open the feed gate to add materials into the storage tank (<1 / 3 of the storage tank volume), and close the feed gate (ball valve) after the materials are filled. Open the booster valve to press into the storage tank. The punching pressure ≥0.6Mpa supports the refractory material head to reach 20m-30m. After checking the pressure on the pressure gauge to reach the specified value, open the discharge valve and adjust the booster valve opening according to the discharge situation. Control the opening at 0-70% to prevent excessive air intake, which will cause material ejection from the discharge pipe, affect the construction quality of refractory materials, and improve the feeding capacity. After the injection of materials is completed, first close the booster valve and the discharge valve, and then close the booster valve to complete the refractory repair injection operation.
