Description

Technical Field

[0001] The present invention relates to the technical field of observation windows, and particularly to an observation window for observing the operating conditions of equipment. Background Art

[0002] With the continuous improvement of environmental protection requirements in industrial production, equipment such as energy-saving heat exchange incinerators (TNV / TO) and three-tower regenerative thermal oxidizers (RTO) are widely used in the field of waste gas treatment. These devices are mainly used to treat harmful gases generated during industrial production, and convert harmful substances in the waste gas into harmless substances through high-temperature incineration or oxidation reactions, thereby achieving the purpose of purifying the environment. However, with the continuous progress of long-term high temperature, high pressure and chemical reactions, the heat exchangers inside the equipment are prone to problems due to the accumulation of gums or other impurities. Especially during the heat exchange process, the phenomenon of gum accumulation will affect the heat exchange efficiency and even pose a potential safety hazard of combustion.

[0003] In the design and use of traditional incinerators and regenerative thermal oxidizers, there is often a lack of means for real-time observation of the internal working state of the equipment. During the operation of the equipment, the situation of gum accumulation usually cannot be monitored in time, resulting in the influence of the heat exchange effect of the equipment when the gum accumulation is excessive, thereby reducing the combustion efficiency, increasing energy consumption, and even causing equipment failures or safety accidents. For operators, although they can check the gum accumulation situation by regular shutdown and maintenance, this method not only requires additional labor costs and shutdown time, but also may miss the potential risks brought by gum accumulation, leading to equipment damage and production stagnation.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop an observation window for observing the operating conditions of equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide an observation window for observing the operating conditions of equipment to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A technical solution for an observation window to observe the operating condition of a device, including a device installation area, on which an observation window is installed. The observation window includes a window shell, on the front of which a window inner frame is provided. On the adjacent sides of the window inner frame, a window outer frame is provided. A ceramic fiber belt is arranged between the window inner frame and the window outer frame. A valve switch handle is arranged on the side of the window shell. A main shaft is installed on the valve switch handle. The main shaft is located inside the window shell. Two sets of ribs are arranged outside the main shaft. A lock sleeve is arranged between the two sets of ribs. Lock seats are arranged at both ends of the lock sleeve. The lock seats and the lock sleeve are connected by lock bolts. A valve plate is connected between the two lock seats. The valve plate is located inside the window shell and abuts against the inner wall of the shell.

[0008] As a preferred technical solution, shaft holes are penetratedly arranged on the ribs, and the shaft holes are clamped with the main shaft.

[0009] As a preferred technical solution, packing fixing seats are arranged on both sides of the window shell. Graphite packing is arranged inside the packing fixing seats. The main shaft penetrates through the graphite packing and is rotatably connected with it. Retaining rings are arranged at both ends of the main shaft on the inner side of the window shell. The retaining rings are closely attached to the inner wall of the shell.

[0010] As a preferred technical solution, a two-way stainless steel air pipe is arranged between the window inner frame and the window outer frame.

There are two groups of ribs 37 outside the main shaft, between the two groups of ribs there is a lock sleeve 372, at both ends of the lock sleeve there are lock sleeve seats 381, the lock sleeve seats and the lock sleeve are connected by a lock bolt 39, and between the two groups of lock sleeve seats there is a valve plate 38. The valve plate is located inside the window shell and abuts against the inner wall of the shell.

[0024] There is a shaft hole 371 penetrating through the rib, and the shaft hole is clamped with the main shaft.

[0025] On both sides of the window shell there are packing fixing seats 31, inside the packing fixing seats there is graphite packing 32. The main shaft penetrates through the graphite packing and is rotatably connected thereto. At both ends of the main shaft on the inner side of the window shell there are retaining rings 34, and the retaining rings are closely attached to the inner wall of the shell.

[0026] Between the window inner frame and the window outer frame there is a two-way stainless steel air pipe 25.

[0027] The window outer frame is embedded with an observation glass 41, the observation glass is sealed with sealant, and on the adjacent side of the valve plate there is a sealing ring 42.

[0028] On the valve switch handle there is a handle locking tooth plate 36.

[0029] The observation window of the present invention can effectively observe the operating condition of the device, timely discover and handle problems such as accumulated glue, and improve the stability and safety of the device operation. The settings of structures such as ceramic fiber belt, graphite packing, and sealing ring ensure the sealing performance and high-temperature resistance of the observation window, and avoid problems such as window damage or leakage caused by high temperature, high pressure, and chemical reactions.
