Abstract

The utility model discloses a composite pyrophyllite pressing block, which is formed by abutting two pieces of pyrophyllite, wherein the pyrophyllite comprises a pyrophyllite mother block and a pyrophyllite sub-block that are buckled with each from the matching ends; for the matching end of the pyrophyllite mother block, the inner diameter is less that the outer diameter; for the pyrophyllite sub-block, the outer diameter is more than the inner diameter; and the size of a through hole formed by buckling the pyrophyllite mother block and the pyrophyllite sub-block is consistent. The pyrophyllite pressing block is formed by abutting and buckling the matching ends of the pyrophyllite mother block and the pyrophyllite sub-block, the matched parts are tightly connected with each other, and the sealing property is good, thereby preventing the internal high-temperature and high-pressure gas and vapor of the composite block from leaking out and effectively protecting an anvil from being damaged by the leaked gas and vapor, so as to greatly prolong the service life of the anvil and lower the production cost. A dolomite pipe is sheathed in the through hole of the pyrophyllite mother block and the pyrophyllite sub-block in a tightly matching way, thereby not only enhancing the pressure transmission property of the composite block, but also further improving the sealing effect of the pyrophyllite pressing block.

Description

A kind of compound pyrophillite briquetting

Technical field

The utility model belongs to the superhard material synthesis technical field, particularly a kind of compound pyrophillite briquetting.

Background technology

In the synthetic field of superhard material, be example to produce diamond, the flow process of its production work is: loose mail is assembled into piece-synthetic-friendship warehouse-purification-type selecting-packing-market.Wherein, loose mail is assembled into piece as first operation, acts on extremely important.At present, Chang Yong pyrophillite piece be by two symmetrically, measure-alike half block constitutes.Because the half block that is two same sizes combines, in the synthetic piece middle that assembles the slit is arranged one, after pressurized, heated, the meetings such as steam that the gas that the foreign gas in the graphite, pyrophillite phase transformation produce and the crystallization water are separated out are leaked from intermediate gap, are injected on the hammer of top.Because the temperature of gas leakage and steam is up to 1500 ℃, will inevitably cause certain burn to the top hammer, promptly hammer the trace that stays the linearly shape of black with the contact site of synthetic piece into shape, along with the increase of synthetic number of times on the top, burn injury increases the weight of gradually, breaks until the top hammer and scraps.

The utility model content

The purpose of this utility model is at above-mentioned deficiency, a kind of good airproof performance is provided, can effectively prevents to push up the compound pyrophillite briquetting that hammer damages.

For achieving the above object, the technical solution of the utility model is: a kind of compound pyrophillite briquetting, form by two pyrophillite piece butt joints, described pyrophillite piece is divided into pyrophillite mother tuber and the sub-piece of pyrophillite that fastens mutually from abutting end, the internal diameter size of pyrophillite mother tuber abutting end is less than outside dimension, the outside dimension of the sub-piece abutting end of pyrophillite is greater than internal diameter size, and the pyrophillite mother tuber is consistent with the clear size of opening that the sub-piece of pyrophillite fastens formation.

Tight fit is arranged with the white clouds madreporic canal in the through hole of described pyrophillite mother tuber and the sub-piece of pyrophillite.

Compared with prior art, the utility model has the advantages that:

1, the pyrophillite briquetting is formed by the abutting end butt joint fastening of pyrophillite mother tuber and the sub-piece of pyrophillite; matching part connects closely; good seal performance; prevent that the gas of HTHP in the synthetic piece and steam are to external leakage; effectively protection top hammer is avoided the infringement of gas leakage and steam; improve the top hammer life-span greatly, reduce production costs.

2, tight fit is arranged with the white clouds madreporic canal in the through hole of pyrophillite mother tuber and the sub-piece of pyrophillite, has both strengthened the pressure transmission performance of synthetic piece, further improves the sealing effectiveness of pyrophillite briquetting again.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and compound pyrophillite briquetting shown in Figure 5, it is formed by two pyrophillite piece butt joints, described pyrophillite piece is divided into from abutting end 5 and abutting end 6 mutual pyrophillite mother tuber 1 and the sub-pieces 2 of pyrophillite that fasten, the internal diameter size of the abutting end of pyrophillite mother tuber 1 is less than its outside dimension, the outside dimension of the abutting end of the sub-piece 2 of pyrophillite is greater than its internal diameter size, and the sub-piece 2 of pyrophillite mother tuber 1 and pyrophillite fastens through hole 3 consistent size that form.Tight fit is arranged with white clouds madreporic canal 4 in the through hole 3 of pyrophillite mother tuber 1 and the sub-piece 2 of pyrophillite, to strengthen pressure transmission and sealing property.

In the utility model, the outward appearance of pyrophillite briquetting can be cube structure, also can be cylindrical structure.

Claims

1. compound pyrophillite briquetting, form by two pyrophillite piece butt joints, it is characterized in that: described pyrophillite piece is divided into pyrophillite mother tuber and the sub-piece of pyrophillite that fastens mutually from abutting end, the internal diameter size of pyrophillite mother tuber abutting end is less than outside dimension, the outside dimension of the sub-piece abutting end of pyrophillite is greater than internal diameter size, and the pyrophillite mother tuber is consistent with the clear size of opening that the sub-piece of pyrophillite fastens formation.

2. compound pyrophillite briquetting as claimed in claim 1 is characterized in that: tight fit is arranged with the white clouds madreporic canal in the through hole of described pyrophillite mother tuber and the sub-piece of pyrophillite.
