Description

Technical Field

[0001] The utility model belongs to the technical field of electronic glass manufacturing equipment, and particularly relates to a protection device for an observation glass of an image type liquid level gauge. Background Art

[0002] In the process of electronic glass production, the control effect and stability of the liquid level in the glass melting furnace are directly related to the melting quality of the glass, raw material consumption, and the output and quality of the finished product. In addition, too large fluctuations in the glass liquid level will exacerbate the erosion of the refractory material on the pool wall of the glass melting furnace, thereby affecting the service life of the furnace and also posing a risk of overflow. Therefore, the monitoring of the glass liquid level is very important in the glass production process.

[0003] At present, in the process of electronic glass production, an image type liquid level gauge is generally used to detect the liquid level. Due to the internal and external pressure difference caused by the working section pressure, the liquid level gauge and the observation glass are severely eroded, resulting in unstable liquid level display data and increasing the frequency of replacing the observation glass, and the liquid level is out of control.

[0004] The traditional observation glass is completely open and is located between the observation hole and the image type liquid level gauge to protect the image type liquid level gauge, but no protection is provided for the observation glass itself, so that the erosion is serious and the collection of liquid level parameters by the liquid level gauge is affected.

[0005] The present utility model is proposed due to the above problems. Utility Model Content

[0006] In order to solve the problems raised in the above background art, the present utility model provides a protection device for an observation glass of an image type liquid level gauge. The purpose of this invention is to reduce the erosion of the working section kiln pressure on the observation glass, reduce the adverse effects on the liquid level gauge, ensure the stable operation of the equipment, and improve the stability of liquid level control.

[0010] Furthermore, it includes an air compression pipe connected to a compressed air source. The air compression pipe is connected to the fixing device through a trachea interface, and the compressed air blown out by the air compression pipe forms a horizontal air curtain wall.

[0011] Further, a shunt compression tube is provided on the air compression tube, and air nozzles are respectively provided on the shunt compression tube. Compressed air blown out from the air nozzles forms a transverse air curtain wall.

[0012] Further, the compressed air forms a transverse air curtain wall that blows towards the observation glass.

[0013] Further, the fixing device further includes a card slot for the observation glass to be inserted into. The card slot has a front cavity in front of the observation glass and a rear cavity behind it.

[0014] Further, the fixing device further includes a liquid level gauge fixing device for fixing the image type liquid level gauge. A front cavity is formed between the image type liquid level gauge and the observation glass.

[0015] Further, the transverse air curtain wall blows towards the rear cavity between the image type liquid level gauge and the observation glass.

[0016] Further, the shunt compression tubes are longitudinally and evenly distributed.

[0017] Further, bolt holes are provided on the liquid level gauge fixing device.

[0018] Further, the card slot is provided with a bayonet, which is located on the opposite side of the transverse air curtain wall.

[0019] The beneficial effects of the present utility model are as follows:

[0029] Reference Figures 1-3 As shown, a specific implementation manner of a protection device for an image type liquid level gauge viewing glass. The device is outside the glass melting furnace and includes a fixing device 100 internally provided with a viewing glass 200 and an image type liquid level gauge 300, which is used to stably fix the viewing glass 200 and the image type liquid level gauge 300. The viewing glass 200 is polluted and corroded by the environment of the melting furnace due to the pressure difference between the inside of the fixing device 100 and the melting furnace; thus, the viewing glass is made of a material with high light transmittance, corrosion resistance and wear resistance.

[0030] Reference Figure 2As shown, the observation glass 200 is fixed by the card slot 120 in the fixing device 100. The card slot 120 has a front cavity 121 in front of the observation glass 200 and a rear cavity 122 behind it. The fixing device 100 further includes a liquid level gauge fixing device 130 for fixing the image type liquid level gauge 300, and an observation port 110 for the image type liquid level gauge 300 to cooperate with the observation glass 200 to observe the glass liquid level in the melting furnace. Thus, the front cavity 121 is located between the image type liquid level gauge 300 and the observation glass 200, and the rear cavity 122 is located between the observation port 110 and the observation glass 200.

[0031] In the direction towards the glass liquid level of the melting furnace, their installation order is the observation port 110, the observation glass 200, and the image type liquid level gauge 300 in sequence.

[0032] The observation glass 200 is in direct contact with the air pressure in the melting furnace. The melting furnace pressure will cause the observation glass to be contaminated and corroded, reducing the measurement accuracy and the service life of the instrument. To protect the image type liquid level gauge 300 and the observation glass 200, a horizontal air curtain wall 410 is provided on one side in the fixing device 100 to weaken the longitudinal melting furnace working part pressure coming in around the observation glass 200. This device can effectively prevent the observation glass from being contaminated, corroded, and collided, and is also convenient for cleaning and maintenance, improving the measurement accuracy and the service life of the instrument.

[0033] In a further embodiment, the horizontal air curtain wall 410 comes from a compressed air source, and its structure is as shown in Figure 1 、 2 As shown, the blowing direction of the horizontal air curtain wall 410 is from right to left. The air from the compressed air source is conveyed through the air compression pipe 420. The air compression pipe 420 is connected to the fixing device 100 through the air pipe interface 430. The compressed air blown out by the air compression pipe 420 forms the horizontal air curtain wall 410. By using the compressed air to generate a strong horizontal pressure inside it, the erosion brought by the kiln pressure to the observation glass 200 can be offset, and the observation glass 200 can be effectively prevented from being contaminated and corroded, maintaining the cleanliness of the observation glass 200.

[0034] In a further embodiment, the air compression pipe 420 is provided with a shunt compression pipe 421, and air nozzles 422 are respectively arranged on the shunt compression pipe 421. The compressed air blown out by the air nozzles 422 forms the horizontal air curtain wall 410. The horizontal air curtain wall 410 formed by the compressed air blowing towards the observation glass 200 uses the compressed air to generate a strong horizontal pressure inside it, offsetting the erosion brought by the kiln pressure to the observation glass 200.

[0035] In a further embodiment, three shunt compression tubes 421 are longitudinally and uniformly distributed, which are consistent with the longitudinal direction of the observation glass 200. The three shunt compression tubes 421 blow the transverse air curtain wall 410 towards the observation glass 200 through the front cavity 121 in front of the observation glass 200 and the rear cavity 122 behind it, offsetting the longitudinal pressure of the working section of the melting furnace coming in, and can effectively prevent the observation glass 200 from being contaminated and corroded, and maintain the cleanliness of the observation glass 200.

[0036] Among them, the liquid level gauge fixing device 130 of the built-in image type liquid level gauge 300 is fixed through the bolt holes 131 opened.

[0037] And the card slot 120 is provided with a bayonet 121 for the observation glass 200 to be inserted, which is located on the opposite side of the transverse air curtain wall 410. As shown in Figure 1 , 2 , the transverse air curtain wall 410 blows from the right to the left and blows out from the left.

[0038] During the use of this device, by connecting compressed air, the strong transverse pressure is generated inside the protection device by using the compressed air, which offsets the erosion brought by the kiln pressure to the observation glass 200, maintains the cleanliness of the observation glass, thereby prolonging the service life of the observation glass 200 and the stable period of the feedback data of the image type liquid level gauge 300, and at the same time reducing the frequency of manual replacement of the image type liquid level gauge 300 and the cost of the observation glass.

[0039] The fixing device 100 fixes the metal shell of a fixed specification corresponding to the observation glass 200 of the corresponding specification. When replacing, only the old observation glass needs to be drawn out and the new observation glass is inserted along the original path, and the operation is convenient.

[0040] After the protection device for the observation glass of the image type liquid level gauge has been put into production and use for a period of time, after 2 months of testing, the effect is good, which has greatly reduced the erosion brought by the kiln pressure to the observation glass 200, prolonged the service life of the observation glass 200, and reduced the frequency of manual replacement and the cost of the glass.
