Description

Technical Field

[0001] The utility model belongs to the technical field of rectifiers, and in particular relates to a ceramic protection type rectifier for a powder online anemometer. Background Art

[0002] The powder online anemometer is a special application of the insertion vortex flowmeter. Based on the principle of the Karman vortex phenomenon in fluid mechanics, the insertion vortex flowmeter is usually used to measure the flow velocity and flow rate of media such as air, water, and steam.

[0003] Most powder online anemometers use an integrated structure for the part inserted into the pipe, and the insertion rod cannot be disassembled. When the sensor or the insertion rod is damaged, the sensor and the insertion rod need to be replaced together, which has a high replacement cost. At the same time, the sensor and the insertion rod are easily damaged during use, causing economic losses. In view of this, we propose a ceramic protective rectifier for powder online anemometers. Utility Model Content

[0004] The utility model aims to provide a ceramic protection rectifier for a powder online anemometer to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a ceramic protection rectifier for a powder online anemometer, comprising:

[0007] A support rod, the support rod is arranged above the flange 2, and the bottom of the support rod is fixedly installed with the flange 3, the flange 2 and the flange 3 are fixed by a plurality of bolts 2, and the top of the support rod is fixedly installed with a meter head;

[0008] A ceramic protective cover is sleeved on two flanges 1, a ceramic protective tube is sleeved on the top of the ceramic protective cover and located on the insertion rod, a retaining ring is sleeved on the insertion rod and located on the top of the ceramic protective tube, and a plurality of screws 2 are threadedly connected on the retaining ring.

[0009] In the technical solution, the two flanges 1 and the plurality of bolts 1 are effectively protected by the ceramic protection tube and the ceramic protection cover. When the ceramic protection tube and the ceramic protection cover are worn, first use a screwdriver to remove the plurality of screws 2 from the retaining ring. At this time, the retaining ring no longer limits the ceramic protection tube. Then pull the ceramic protection cover upward, and the ceramic protection cover drives the ceramic protection tube and the retaining ring to move upward. Then, personnel use tools to remove the plurality of bolts 2, and then remove the plurality of bolts 1, and then remove the insertion rod, flange 1, flange 2, ceramic protection cover and ceramic protection tube.

[0010] When it is necessary to install a new insertion rod, flange one, flange two, ceramic protective cover and ceramic protective tube, first fix the two flanges one with several bolts one, then fix flange two and flange three with several bolts two, and finally use a screwdriver to tighten several screws two so that the retaining ring can be fixed on the insertion rod. The retaining ring can limit the ceramic protective cover and the ceramic protective tube so that the ceramic protective cover and the ceramic protective tube will not be displaced. The disassembly is simple and easy to operate, which reduces the replacement cost.

[0011] In the above technical solution, further, the inner side wall of the retaining ring is in close contact with the circumferential side wall of the insertion rod.

[0012] In this technical solution, it is ensured that the position of the retaining ring will not shift after the fixing is completed.

[0013] In the above technical solution, further, the inner wall of the ceramic protection tube is in contact with the outer wall of the insertion rod.

[0014] In this technical solution, it is ensured that the two ceramic protection tubes can protect the insertion rod.

[0015] In the above technical solution, further, the bottom of the retaining ring is in close contact with the top of the ceramic protection tube.

[0016] In this technical solution, it is ensured that the retaining ring can limit the position of the ceramic protection tube after the fixing is completed.

[0017] In the above technical solution, further, the lower end of the ceramic protection tube is plugged into the ceramic protection cover, and the inner wall of the ceramic protection cover is in close contact with the rectifier body, the two flanges and the outer wall of the insertion rod.

[0018] In this technical solution, it is ensured that the ceramic protection cover can be inserted into the ceramic protection tube, so as to protect the rectifier body, two flanges and a plurality of bolts.

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

[0020] 1. The ceramic protection rectifier, ceramic tube and ceramic protective cover of the powder online anemometer effectively protect the flange and bolts fixing the vortex sensor, enhance the wear resistance and increase the service life of the anemometer.

[0021] 2. For the ceramic protective rectifier of the powder online anemometer, when the ceramic protective tube and the ceramic protective cover are worn, first use a screwdriver to remove several screws 2 from the retaining ring. At this time, the retaining ring no longer limits the ceramic protective tube. Then pull the ceramic protective cover upward, and the ceramic protective cover drives the ceramic protective tube and the retaining ring to move upward. Then, personnel use tools to remove several bolts 2, and then remove several bolts 1. Then, take out the insertion rod, flange 1, flange 2, ceramic protective cover and ceramic protective tube. The insertion rod, flange 1, flange 2, ceramic protective cover and ceramic protective tube can be replaced as a whole, reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
