Description

Technical Field

[0001] The utility model relates to an auxiliary device for disassembling a CEMS sampling probe filter element. Background Art

[0002] A CEMS sampling probe refers to a device that continuously monitors the concentration and total emission of gaseous pollutants and particulate matters emitted from air pollution sources and transmits the information to the competent department in real time. During the operation of the CEMS sampling probe, the filter element may become blocked. In this case, the filter element needs to be disassembled and replaced. Since the temperature during the operation of the filter element reaches more than 150 degrees, the probe is tightened, which increases the difficulty of disassembling the filter element. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and provide an auxiliary device for disassembling a CEMS sampling probe filter element.

[0004] The above purpose is achieved through the following technical solutions:

[0005] An auxiliary device for disassembling a CEMS sampling probe filter element, which comprises an adjusting ring and a buckle ring. The adjusting ring is rotatably connected with the buckle ring. Clamping devices are respectively connected to the four circumferences of the adjusting ring. A cross plate is arranged on the end face of the buckle ring, and a locking bolt is threadedly connected to the cross plate.

[0006] For the auxiliary device for disassembling a CEMS sampling probe filter element, the clamping device comprises an arc-shaped clamping plate and a sliding rod. The sliding rod passes through the adjusting ring and is fixed on the arc-shaped clamping plate. An adjusting bolt passes through a threaded hole of the adjusting ring and is rotatably connected with the arc-shaped clamping plate.

[0007] For the auxiliary device for disassembling a CEMS sampling probe filter element, a rubber pad is fixed on the arc-shaped clamping plate. Beneficial Effects

[0008] 1. When the utility model is used, the outer ring surface of the filter element is clamped by the clamping device, and then the filter element can be disassembled by holding the sliding rod and rotating, ensuring the smooth disassembly of the filter element.

[0009] 2. The utility model has a simple structure and can be applicable to the disassembly of filter elements with different diameters. Description of the Drawings

[0012] Att Figure 3 is a right view of the utility model;

[0013] Appended Figure 4 is a schematic structural diagram when the present utility model is in use;

[0014] In the figure: 1, arc-shaped clamping plate; 2, rubber pad; 3, adjusting bolt; 4, sliding rod; 5, adjusting ring; 6, snap ring; 7, locking bolt; 8, cross plate; 9, filter element; 10, fixed head; 11, annular groove. Specific embodiments

[0015] Referring to Figures 1 - 3 , a CEMS sampling probe filter element disassembly assisting device, which comprises an adjusting ring 5 and a snap ring 6. The adjusting ring is rotatably connected with the snap ring. An annular groove 11 is formed in the annular surface of the snap ring. The end of the adjusting ring is inserted into the annular groove. Clamping devices are respectively connected to the four circumferences of the adjusting ring. The end surface of the snap ring has a cross plate 8, and a locking bolt 7 is threadedly connected to the cross plate.

[0016] For the CEMS sampling probe filter element disassembly assisting device, the clamping device comprises an arc-shaped clamping plate 1 and a sliding rod 4. The sliding rod passes through the adjusting ring and is fixed on the arc-shaped clamping plate. The adjusting bolt 3 passes through the threaded hole of the adjusting ring and is rotatably connected with the arc-shaped clamping plate.

[0017] For the CEMS sampling probe filter element disassembly assisting device, a rubber pad 2 is fixed on the arc-shaped clamping plate.

[0018] Working principle: Referring to Figure 4 , when the filter element 9 needs to be removed, after removing the filter element body of the sampling probe, the device is buckled on the filter element body, and then the snap ring and the fixed head are fixed by bolts. There are four fixed threaded holes on the fixed head, and these fixed threaded holes are self-provided threaded holes for fixing the filter element body. After fixing the device, the adjusting ring is sleeved on the filter element and its adjusting ring is inserted into the annular groove of the snap ring, and then the adjusting bolt is rotated to make the arc-shaped clamping plate slide into contact with the filter element. After adjusting the four clamping devices respectively so that the arc-shaped clamping plates of each clamping device are in contact with the filter element and then stop, at this time, adjust each adjusting bolt again to make the arc-shaped clamping plate move to abut tightly against the filter element. In this way, the four clamping devices realize tight clamping of the filter element. Then, hold the two opposite sliding rods by hand to rotate the adjusting ring. The filter element is threadedly connected to the fixed head, so that the filter element can be loosened. During the screwing process, the adjusting ring can rotate and slide relative to the snap ring until the filter element is unscrewed. Then, rotate the adjusting bolt in the reverse direction to make the arc-shaped clamping plate move away from the filter element, and then take out the filter element.
