Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silica brick detection, especially to a detection mechanism of refractory silica brick. BACKGROUND

[0002] Silica brick is acid-resistant refractory material, has good acid slag erosion resistance, the load softening temperature is as high as 1640~1670 DEG C, and the volume is relatively stable during long-term use at high temperature.

[0003] A high-density silica brick high-temperature air permeability tester is disclosed in Chinese patent CN218956007U. The high-density silica brick high-temperature air permeability tester has a heating box that maintains the internal temperature, a fan, and a gas leakage detector that can detect the air permeability of high-density silica brick. The temperature sensor can detect the temperature of high-density silica brick through the heat plate, which brings convenience to the work of the staff. However, the high-density silica brick high-temperature air permeability tester has the following defects while solving the problem:

[0004] The fan blows the airflow from above to the silica brick, and then the gas leakage detector below the silica brick detects the air permeability. This method has limited airflow pressure because the fan directly blows the airflow to the silica brick. Therefore, when the airflow is blown to the silica brick, it may disperse in all directions and then be discharged upward, which prevents the gas leakage detector from detecting the air permeability of the silica brick. SUMMARY

[0005] The present utility model aims to solve at least one of the technical defects in the background art.

[0006] Therefore, the present utility model aims to provide a detection mechanism of refractory silica brick to solve the problem of insufficient air pressure of the high-density silica brick high-temperature air permeability tester, which may prevent the gas leakage detector from detecting the air permeability of the silica brick.

[0007] To achieve the above-mentioned purpose, the embodiment of the present utility model provides a detection mechanism of refractory silica brick, which includes a bottom plate and an air pump. The top of the bottom plate is installed with a gantry. The top of the gantry is screw-connected with a screw rod. The top end of the screw rod is fixedly connected with a handle. The bottom of the screw rod is fixedly installed with a gas cover. The bottom of the gas cover is fixedly connected with a sealing gasket. The outer surface of the gas cover is provided with an air inlet pipe and a detection pipe. The end of the detection pipe is fixedly installed with an air pressure gauge.

[0008] The beneficial effect is that the refractory silica brick to be detected is placed above the bottom plate, the air cover is pressed on the top surface of the refractory silica brick by being lowered, then air is sent into the air cover by the air charging pump, when the air pressure in the air cover reaches a certain value, the air charging pump stops charging, at this time, the air pressure drop value in a certain time is measured by timing observation of the air pressure gauge, so that the air permeability of the refractory silica brick is judged, and the air emission direction is limited, the air pressure gauge can reflect the air pressure in the air cover in real time, so that the air permeability of the refractory silica brick is accurately judged.

[0009] Preferably, the top of the air cover is fixedly connected with a sleeve, the bottom end of the screw rod is fixedly connected with a ball head, and the ball head is movably inserted into the inside of the sleeve.

[0010] The beneficial effect is that when the top surface of the refractory silica brick is not horizontal with the bottom plate, the air cover can move when the air cover presses the refractory silica brick downward, so that the bottom of the air cover can be closely attached to the top surface of the refractory silica brick, and air leakage is avoided, so that the device can be normally used.

[0011] Preferably, the portal frame is slidably connected to the two sides of the bottom plate, and the screw rod is slidably connected to the top of the portal frame.

[0012] The beneficial effect is that when multiple points on the refractory silica brick need to be detected, the screw rod can be loosened, then the portal frame and the screw rod are slid, the air cover is adjusted to the corresponding detection point on the refractory silica brick, and then the air cover is lowered for detection, so that multiple point detection is facilitated.
