Description

Crucible support for determining coarse ash content of feed

Technical Field

The utility model belongs to the technical field of the formula feed detects, concretely relates to a crucible holds in palm piece for fodder coarse ash content survey.

Background

The coarse ash is an index for controlling the quality of the feed and refers to the residue left after all organic substances are oxidized in a high-temperature furnace at the temperature of 550-600 ℃. Mainly inorganic substances such as mineral oxides or salts and the like, and sometimes a small amount of silt is contained, and the feed quality is poor due to the fact that the coarse ash content is too high. In laboratory measurement, generally, carbonization is carried out to no smoke, then the dried fruits are transferred to a high-temperature furnace for burning, a small opening needs to be opened on a dried fruit cover in the carbonization and burning processes, so that the air can be conveniently and fully contacted with a sample in a crucible, and the ashing and the burning are completely guaranteed.

Crucible tongs live time among the prior art is one long, and the department dislocation is serious to middle circular clamp, and easy landing when pressing from both sides with well choir, so the clamp of crucible is got and is adopted crucible tongs to stretch into crucible tongs in the gap that the crucible lid was opened more and get, but crucible tongs stretch into crucible tongs and get and take the sample sometimes out because at the ashing in-process, the sample of tiny granule can the adhesion around the crucible wall, discovery accidental error is great in the experiment of comparing with standard sample.

And the crucible tongs that use in the high temperature furnace are mostly big and long crucible tongs, and careless a little in actual field operation, overturn the crucible easily, cause this experiment failure on the one hand, and unrestrained sample dregs clearance on the other hand is loaded down with trivial details, in case the clearance is unclean, will glue in the crucible bottom, causes the crucible not constant weight, brings great error for the experiment, and the crucible value difficulty of not constant weight easily leads to the experiment failure.

In the prior art, a crucible supporting piece is also provided, the supporting piece type crucible tongs disclosed by the utility model CN201420452577.1 has the advantages that in the actual operation, the arc-shaped tongs are ensured to support the crucible, so the closing-in of the crucible tongs cannot be too large, otherwise the crucible can fall off, but the closing-in of the front end of the arc-shaped tongs is narrow, the arc-shaped tongs need to support the crucible for operation at a far end after extending into a high-temperature furnace operating room, the flexibility during manual control is poor, after the high-temperature furnace is opened, an experimenter stands at the front end of the high-temperature furnace, the sight is influenced during heat emission, the narrow arc-shaped tongs are difficult to accurately support the crucible, and the crucible is knocked down; the crucible turnover means that the test fails and a large amount of subsequent hearth cleaning work is troublesome. On the other hand, the high temperature furnace is daily placed on the laboratory bench of about one meter two, or lower, when getting the crucible, the arc forceps holder of operating personnel handheld often can form the contained angle with furnace, and difficult exemption produces the scraping to the refractory material in the furnace, and the smoothness of flame retardant coating is also great to the influence of constant weight class experiment, and when the flame retardant coating had scraping and powder to drop, very easy bonding was in the crucible bottom, caused the crucible not constant weight.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a crucible holds in palm piece for fodder coarse ash content survey to crucible tongs presss from both sides and gets the problem of easily overturning, easily gluing the appearance in solving the ash content survey.

In order to solve the above problems, the utility model discloses technical scheme does:

the utility model provides a crucible holds in palm piece for fodder coarse ash survey, includes die-pin, arc portion, handle, and arc portion and handle are established respectively at the both ends of die-pin, and the both ends opening part symmetry of arc portion is equipped with the location extension, and the contained angle between location extension and the arc portion is 75 ≤ alpha ≤ 115, and the perk that makes progress of location extension, and the contained angle between the plane that two location extensions are constituteed and the arc portion plane is 5 ≤ beta ≤ 15.

Furthermore, the front end of the handle is provided with soft heat insulation cloth.

Further, the support rod is fixedly connected with the arc-shaped part through an anchor bolt.

Furthermore, arc portion and location extension be integrated structure, adopt high carbon steel wire to make.

The utility model has the advantages as follows:

(1) the utility model symmetrically arranges the positioning extension parts at the openings at the two ends of the arc part, the positioning extension parts and the arc part form an outward-extended positioning area, so that the crucible can enter the arc part through the positioning area when the remote end is operated conveniently, the influence factor that the crucible is easy to overturn due to the narrow opening of the arc part is eliminated, and the failure probability of the experiment is greatly reduced; the included angle between the arc-shaped part and the positioning extension part is defined for convenience of operation, when the included angle is small, the folded angle at the joint between the arc-shaped part and the positioning extension part is obvious, when the crucible is held up, the folded angle can knock over the crucible carelessly, when the included angle is large, the expansion of the positioning area is not obvious, the function of the positioning extension part can be ignored, and the setting significance of the positioning extension part can be lost; the upward tilting of the positioning extension part is based on the fact that the high-temperature furnace is placed lower in actual operation, the furnace bottom fireproof part is easy to scratch, when the positioning extension part tilts upward, the end part of a crucible supporting piece extending into a hearth of the high-temperature furnace can be prevented from directly colliding with the furnace bottom fireproof part to scratch, meanwhile, the deformation of the positioning extension part and the arc-shaped part is avoided, and the service life of the positioning extension part is prolonged; repeated practice shows that the beta angle is limited, the angle is too large, the steel plate is easy to flatten when being placed in normal times when upwarping is obvious, and the scraping prevention effect cannot be generated when the upwarping angle is too small;

(2) the arrangement of the soft heat insulation cloth is different from the hard heat insulation board in the prior art, and the soft heat insulation cloth covers the hands of an operator holding the handle in actual operation, does not block the sight and is more practical;

(3) the support rod is fixedly connected with the arc-shaped part through an anchor nail, the mode is simplest and most convenient and light, and the operation flexibility and controllability are better as the support rod is a light part;

(4) the arc-shaped part and the positioning extension part are of an integrated structure and are made of high-carbon steel wires, so that the strength and the hardness are high, the cold plastic deformation capability is poor, underground deformation is difficult at normal temperature and low temperature, and the service life is longer;

(5) the utility model discloses a reasonable improvement, the experimental operation flow who fits reality more, simple structure, preparation convenience, low cost, it is light and handy durable, seem slight change and improve the success rate of experiment greatly.
