Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anemometers, in particular to a ceramic protection type plug-in powder anemometer. Background Art
[0002] In practice, the vortex spectrum anemometer is a specialized application of an insertion vortex flowmeter, based on the Karman vortex phenomenon in fluid mechanics. Insertion vortex flowmeters are commonly used to measure the velocity and flow rate of media such as air, water, and steam. However, when used to measure the velocity of pulverized coal (powdered coal refers to particles less than 0.5 mm in size and traveling at 25 m / s), it wears out within five months. Our technicians, after inspecting and testing the vortex generator, identified wear issues that required improvement. Utility Model Content
[0003] The purpose of the utility model is to provide a ceramic protection type insertion type powder anemometer to address the defects and shortcomings of the existing technology.
[0004] The utility model describes a ceramic protective insertion type powder anemometer, comprising an insertion rod, the rear end of which is connected to a support rod via a small flange and a mounting flange, the rear end of the support rod being equipped with a meter head which is fastened by a locking nut; the front end of the insertion rod being connected to a split wear-resistant meter body; a split wear-resistant vortex generator being installed at the front end of the split wear-resistant meter body, which is fastened by an inner hexagonal screw, and the split wear-resistant vortex generator and the split wear-resistant meter body being designed to be a detachable structure.
[0005] Furthermore, a ceramic protective cover is installed on the insertion rod.
[0006] Furthermore, a ceramic protection tube is installed on the insertion rod, and a retaining ring is installed at the front end of the ceramic protection tube.
[0007] Furthermore, the split wear-resistant surface body is made of high-hardness alloy.
[0008] After adopting the above structure, the beneficial effects of the present invention are as follows: the ceramic protective insertable powder anemometer described in the present invention adopts a split wear-resistant surface body made of cemented carbide. The split wear-resistant vortex generator in the split wear-resistant surface body is installed by an inner hexagonal screw, and forms a pipe passage with the same diameter as the split wear-resistant surface body. The vortex generator at the front end of the split wear-resistant surface body is the first to suffer wear. Depending on the degree of wear during industrial and mining operation, it can be regularly checked during the maintenance period, and the front end vortex generator can be disassembled and replaced, which facilitates maintenance and reduces operating costs, thereby increasing the service life of the overall anemometer.

[0016] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
