Abstract

The utility model discloses a high reliability and high efficiency coal ash melting quality measuring instrument, which belongs to the coal quality analysis device. The utility model comprises a machine shell, a camera and an observation box and a corundum pipe which are arranged in the machine shell, an ash cone pallet which is arranged on the porcelain boat of the corundum pipe. The observation box comprises a square or rectangular box which is three surface opening, a semi-reflection and semi-translucent spectroscope which separates the light into two directions is arranged vertically in the box at a certain angle. The ash cone pallet is stepped, the ash cone positioning pits on the low surface in the front rows of the stepped ash cone pallet and the positioning pit on the steps of the back row are staggered. The utility model has the advantages that the difficulty of simultaneously observation in two directions is overcomed, also timely monitoring for each sample during the experiment is convenient.

Description

Coal ash melting property determinator

Technical field

The utility model belongs to the coal analysis testing apparatus, is specifically related to a kind of coal ash melting property determinator.

Background technology

At present, because the needs of experiment, existing advanced ash melting property determinator has all adopted manual observation and microcomputer two functions of identification automatically, but has only a viewport.Therefore, can not accomplish in Intelligent Recognition, to carry out manual observation, can only observe and microcomputer identification switching by artificial, even or manually can monitor whole process, but microcomputer at interval property carry out monitors identified, so just caused free dead angle in experimentation, might cause error in the moment of key.

Though the ash that normal experiment adopts awl supporting plate can be made 7 samples simultaneously, this tends to exist serial problem such as block, and makes troubles to observation, has also influenced the degree of accuracy of experiment simultaneously.Because the ash fusibility determination experiment cycle is longer, so, generally wish to improve the sample number of single experiment for improving conventional efficient.

Summary of the invention

For overcome artificial observe and microcomputer-based intelligent identification handoff procedure in the time dead angle of causing and have the shortcoming of the unfavorable observation that laboratory sample causes for a long time now, the utility model provides a kind of highly reliable and high efficient coal ash melting property determinator.

Concrete technical scheme of the present utility model is: a kind of highly reliable and high efficient coal ash melting property determinator, comprise casing, place camera, observation box, high temperature furnace in the casing, place the ash awl supporting plate on the high temperature furnace porcelain boat, it is characterized in that: described observation box comprises the square or the rectangular box of three perforates, in box, vertically be provided with at a certain angle one with light be divided into two to the half-reflection and half-transmission spectroscope; Described ash awl supporting plate is a step ash awl supporting plate, the setting of staggering of the ash awl positioning pit on the front-seat bottom surface of step ash awl supporting plate and positioning pit on the row's step of back.

Each hole on three faces of box all is in sustained height, and is in sustained height with the viewport of burner hearth.The spectroscope that utilizes a slice half-reflection and half-transmission is divided into two the light of observation panel, thus reach artificial and camera two to observing simultaneously.This makes the people can not influence the automatic identification of microcomputer when wanting to observe, thereby reaches higher measuring accuracy.

In addition, utilize the ash awl supporting plate of a step, draw back time ash discharge and bored the distance that the same ash discharge is bored, promptly reduced the situation such as block between grey awl and the ash awl, simultaneously can make a plurality of samples, promptly guaranteed certain sample size, also drawn the distance of each ash awl bigger, so more helped our experimental observation from horizontal direction.

The utility model has the advantages that: simple in structure, be convenient to observe.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model one-piece construction synoptic diagram;

Fig. 2 is the optical schematic diagram of observation box;

Fig. 3 is the structural representation of observation box;

Fig. 4 is an ash awl support board structure synoptic diagram;

Fig. 5 is the another example structure synoptic diagram of ash awl supporting plate.

Among the figure 1, camera, 2, observation box, 2-1, box, 2-2, half-reflection and half-transmission spectroscope, 2-3. viewport, 2-4, eyes, 2-5, CCD pick-up lens, 2-6, eye-observation hole, 2-7, CCD pick-up lens viewport, 2-8, socket, 2-9, slot, 3, ash awl supporting plate, 3-1, positioning pit, 3-2, positioning pit, 4, porcelain boat, 5, heat-insulation layer, 6, carborunbum tube, 7, alundum tube, 8, casing.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, inject from viewport 2-3 from the light beam that object in the ash melting property determinator emits, by being divided into two a branch of reflected light, a branch of refract light behind the half-reflection and half-transmission spectroscope 2-2.Human eye 2-4 receives reflected light by eye-observation hole 2-6, and CCD pick-up lens 2-5 then receives refract light by pick-up lens viewport 2-7, has so just reached two to uninterrupted observation of while.

As Fig. 2, observation box shown in Figure 32 a lighttight square box 2-1 is arranged, have a bar shaped socket 2-8 at the box end face along diagonal line, the corresponding bar shaped socket of box body inner bottom part has a bar shaped slot 2-9. half-reflection and half-transmission spectroscope 2-2 to be inserted into from bar shaped socket 2-8 in the bar shaped slot 2-9, the spectroscopical size of half-reflection and half-transmission preferably and diagonal plane be equal to.Then in three perforates of level so that light passes through, all the other face seals, and cartridge inner surface carries out not reflective processing.

Example structure synoptic diagram of ash awl supporting plate as shown in Figure 4, supporting plate is a staged, and positioning pit 3-2,3-1, the positioning pit on the table top of the front and back setting of staggering is respectively arranged on the table top of front and back,

Being another example structure synoptic diagram of ash awl supporting plate as shown in Figure 5, is that the latter half at supporting plate is provided with boss, on the first half table top of supporting plate and on the boss face positioning pit 3-2,3-1 is being arranged respectively.

The ash awl supporting plate of said structure, draw back time ash discharge and bored the distance that the same ash discharge is bored, both reduced the situation such as block between grey awl and the ash awl, guaranteed simultaneously certain sample size again, also draw the distance of each ash awl bigger from all directions, so more help the microcomputer-based intelligent identification and the manual observation of image, thereby reduced test error.
