Abstract
The utility model relates to a Y-shaped pin used for increasing the contact area of a wear-resistant, refractory and heat-insulating material for fixation, which comprises a pin main body, wherein a U-shaped base perpendicular to the pin main body is arranged at the bottom of the pin main body, and a branch is formed at the top of the pin main body; and the Y-shaped pin is characterized in that round bars are respectively arranged on two forks of the branch. The utility model has the advantages that the structure and the manufacturing process of the Y-shaped pin are simple, and the Y-shaped pin is convenient for manufacture; the contact area between the pin and the wear-resistant, refractory and heat-insulating material is increased, so that the wear-resistant, refractory and heat-insulating material is fixed more effectively; and an expansion clearance is left between the metal pin and the nonmetallic wear-resistant, refractory and heat-insulating material, thereby preventing the wear-resistant, refractory and heat-insulating material from being extruded broken by the pin when being heated during the running process and also ensuring the stability of the wear-resistant, refractory and heat-insulating material.
Description
Technical field
The utility model relates to a kind of Y shape pin, is used for guaranteeing that the abrasion-proof and refractory and the thermal insulating material that apply in cyclone separator, separator import and export flue, material returning device and the feed back leg are not come off by the bed grinding abrasion.
Background technique
Because cyclone separator, separator are covered with abrasion-proof and refractory and thermal insulating material in importing and exporting in flue, material returning device, the feed back leg.Abrasion-proof and refractory and thermal insulating material are the high density non-metal material, suitable load is arranged, and abrasion-proof and refractory and thermal insulating material are different with the expansion coefficient between metal shell, for guaranteeing that abrasion-proof and refractory and thermal insulating material are not come off the metal pin of the fixation of need having burn-on in the inboard of these metal shells by the bed grinding abrasion.
Existing Y shape pin comprises pin body 1 shown in Figure 1A and Figure 1B, be provided with perpendicular U-shaped base 2 in the bottom of pin body 1, is provided with waveform bifurcated 3 at the top of pin body 1.Although waveform bifurcated 3 can increase the area of contact of pin and abrasion-proof and refractory and thermal insulating material to a certain extent, the situation that still often has abrasion-proof and refractory and thermal insulating material to come off in actual motion occurs.
Summary of the invention
The purpose of this utility model provides a kind of Y shape pin of stopping abrasion-proof and refractory and the appearance of thermal insulating material dropping situations.
In order to achieve the above object, the technical solution of the utility model has provided a kind of fixedly Y shape pin of abrasion-proof and refractory and thermal insulating material area that is used to increase, comprise the pin main body, be provided with perpendicular U-shaped base in the bottom of pin main body, top in the pin main body is provided with bifurcated, it is characterized in that, stick at two of bifurcated and be respectively equipped with round steel.
Further, described round steel is all vertical with two forks of described bifurcated.On the termination of described round steel, be with plastic cap.
The utility model is stuck at two of pin and respectively is welded with the segment round steel, increase Y shape pin and abrasion-proof and refractory and thermal insulating material fixed-area.
The utility model has the advantages that: structure and preparation process are simple, are convenient to make; Increased the area of contact between pin and abrasion-proof and refractory and the thermal insulating material, thus more effective fixedly abrasion-proof and refractory and thermal insulating material; Between metal pin and nonmetal abrasion-proof and refractory and thermal insulating material, leave the clearance for expansion, guaranteed abrasion-proof and refractory and thermal insulating material when operation is heated not by the pin squeeze crack, guaranteed the stable of abrasion-proof and refractory and thermal insulating material.

Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
Shown in Fig. 2 A and Fig. 2 B, a kind ofly be used to increase the fixedly Y shape pin of abrasion-proof and refractory and thermal insulating material area for what the utility model provided, comprise pin main body 1, the bottom of pin main body 1 curves U-shaped, and with pin main body 1 vertical formation U-shaped base 2, be used to increase the area of contact of pin and metal shell, increase the grip of pin.Bifurcated 4 is formed on the top in pin main body 1, and the angle of bifurcated 4 is 75 degree according to the performance decision of abrasion-proof and refractory and thermal insulating material in the present embodiment.Stick at two of bifurcated 4 and respectively to weld a bit of round steel 5, round steel 5 is angled with two forks of described bifurcated 4, and effect is to increase to greatest extent the firm area of pin.On the termination of round steel 5, be with plastic cap 6.These plastic caps can burn because running into high temperature in boiler operatiopn and melt, allow the certain space of appearance between pin and abrasion-proof and refractory and the thermal insulating material, guarantee in the boiler running process between the metal pin and abrasion-proof and refractory and thermal insulating material not because of the different generation stress of swell increment the stability of destruction abrasion-proof and refractory and thermal insulating material.
