A thermocouple is a K-type thermocouple suitable for operating under a condition of a coal-pulverizer internal environment and is introduced from one external end of a protective bushing. When in measurement, a measuring end of the thermocouple is near a measuring point end of the thermocouple. Correlative instruments are connected by an external lead of the thermocouple and measuring-point temperature values are read. The measuring apparatus provided by the utility model can accurately measure the temperature values of the corresponding measuring points of different types of middle-speed coal pulverizers conveniently for a long time based on actual requirements, so that distribution of the internal temperature in the middle-speed coal pulverizer is obtained and is important to research a heat exchange process in the middle-speed coal pulverizer and reasonably optimize and control operation parameters of the coal pulverizer.
Description
Technical field
The utility model belongs to power equipment systems technology field, is a kind of device for medium-speed pulverizer internal temperature field distribution measurement.
Background technology
The medium-speed pulverizer unit pulverized-coal system is to use at present very widely pulverized coal preparation system.The research of medium-speed pulverizer mainly concentrated on coal pulverizer structure and interior flow field aspect thereof at present both at home and abroad, pay close attention to the problems such as coal pulverizer wearing and tearing and flour extraction pipe pulverized coal particle skewness.In order to improve coal pulverizer and genset performance driving economy, can reasonably optimize the operational factor of medium-speed pulverizer.Because there is the heat transfer process of coal and high-temperature hot-air coal pulverizer inside, need to guarantee its Operation safety when optimizing the medium-speed pulverizer operational factor, the temperature field distributes significant for heat transfer process in the research coal pulverizer and reasonably optimizing control coal pulverizer operational factor in the research medium-speed pulverizer.
Summary of the invention
The purpose of this utility model is the deficiency for existing investigative technique and means, and the measurement mechanism of a kind of medium-speed pulverizer internal temperature field distribution is provided.
The technical scheme that its technical matters that solves the utility model adopts is:
The distribution of the medium-speed pulverizer internal temperature field that the utility model device mainly obtains based on numerical simulation and the practical structures of coal pulverizer design, and device comprises protective casing tube bank, thermopair measuring point, tube bank location and disk, annulus flange are installed; The annulus flange matches with the barrel body of medium-speed coal mill flange hole; The protective casing tube bank is that an end is welded with tube bank location and 16 Φ 6 * 1mm stainless steel tube banks that disk is installed, and prevents that thermopair is in the inner too early wearing and tearing of coal pulverizer; Thermopair adopts and to be adapted at the K type thermopair of working under the coal pulverizer interior environmental conditions, and thermopair is introduced by the external end of protective casing tube bank, and the thermocouple measurement end is near the thermopair measuring point end of protective casing tube bank and indentation 1 ~ 2mm slightly during measurement.Outer lead by thermopair is connected to pertinent instruments, reads the measuring point temperature value.
The utility model device is according to the distribution of medium-speed pulverizer internal temperature field, temperature point is arranged in from the mill bowl edge bottom 30 ~ 50mm of coal pulverizer covers crucial heat exchange position on the differing heights layer on the coal pulverizer turning apart from beginning interval 30 ~ 200mm always, mix the initial stage to the Temperature Distribution of the basicly stable whole process of wind powder mixing temperature in order to comparatively comprehensively measure coal pulverizer inside from the wind powder, thereby obtain its heat transfer process.
When the utility model device is installed; it is inner that thermopair is fixed on corresponding protective casing tube bank in advance; protective casing is restrained external end pass from inside to outside coal pulverizer shell flange hole by coal pulverizer inside; the tube bank location of protective casing being restrained external end with welding manner is fixed with disk and annulus flange are installed, and the position of corresponding measuring point is also thereupon fixing.
The beneficial effects of the utility model are as follows: the utility model apparatus structure is simple, can not produce any impact to medium-speed pulverizer structure and the method for operation, can measure accurately for a long time easily the temperature value of corresponding measuring point according to actual needs to the medium-speed pulverizer of different model, and then obtain the distribution of medium-speed pulverizer internal temperature, significant to heat transfer process in the research medium-speed pulverizer and reasonably optimizing control coal pulverizer operational factor.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A schematic cross-section among Fig. 1.
Among the figure: protective casing tube bank 1, thermopair measuring point 2, tube bank location and installation disk 3, annulus flange 4, coal pulverizer 5, coal pulverizer flange hole 6.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the utility model device comprises protective casing tube bank 1, thermopair measuring point 2, tube bank location and disk 3, annulus flange 4 is installed; Protective casing tube bank 1 is made of 16 Φ 6 * 1mm stainless-steel tubes according to point position and coal pulverizer structure; According to 16 thermopair measuring points 2 thermopair is installed in the stainless-steel tube of protective casing tube bank 1, thermocouple terminal is drawn by the other end of protective casing tube bank 1; Tube bank is welded on the tube bank location and installs on the disk 3.
