Description

Anti-spalling net for crucible

Technical Field

The utility model belongs to chemical reagent preparation field relates to an auxiliary device, especially a crucible is with preventing scattered net that splits.

Background

The crucible is a common reaction vessel and is mainly used for experimental processes such as melting and refining metal liquid, solid-liquid heating and the like. The crucible is often in direct contact with an induction cooker or an open flame heat source during heating, and may be cracked during heating or during later movement. For example, in the process of taking out the workpiece after being heated in a high-temperature furnace, the clamping part is subject to uneven stress or strong temperature change, so that the workpiece is easy to fall off and fall off. In addition, because most of the contained high-temperature liquid in the crucible is, in case of spalling, the high-temperature liquid in the crucible can be scattered in all directions, so that operators are easily scalded, and great potential safety hazards exist.

At present, no solution for the above problems exists, which can only optimize the crucible material, and select a crucible of a suitable material for a corresponding experiment, but cannot avoid the above hidden troubles.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide one kind can carry out the cladding with the crucible, does not influence the crucible heating with preventing the spalling net.

The utility model adopts the technical proposal that:

the utility model provides a crucible is with preventing net that splits which characterized in that: the anti-spalling net is of a net bag structure with an upper opening made of alloy wires, and the net bag structure is sleeved at the bottom of the crucible and is heated with the crucible simultaneously in a use state.

And, the string bag structure includes two vertical poles, and two vertical poles are located crucible both sides symmetry each other respectively under the suit state, two down tube that all hinges of both sides tip of two vertical poles be equipped with two down tubes, every down tube all is the obtuse angle with the vertical pole and extends, two down tube tip of homonymy are connected through a connecting ring hinge dress, four down tubes and two vertical poles form the hexagon structure, two go-between that are located the top all make a couple, the upper end of couple is used for along hanging the dress with the crucible outward and fixes, two go-between that are located the below make with the both sides tip of a sill bar is integrative respectively, the sill bar middle part undercut forms "U style of calligraphy", and this sunk part's interval is not less than the external diameter of crucible bottom.

And the end face of the inclined rod on the same side with the crucible forms an arc, and the radian of the arc is matched with the radian of the outer surface of the crucible.

And the upper end part and the lower end part of each longitudinal rod are integrally provided with a closed circular ring, and the circular ring is hinged and fixed with the end part of the inclined rod.

The utility model has the advantages that:

the utility model discloses in, adopt high temperature resistant alloy silk material to make the string bag structure, there is the fretwork region, consequently can not influence the heating of heat source to the crucible. The string bag structure forms the exoskeleton and plays the design effect to the crucible, when the crucible takes place to scatter garrulously, the string bag provides inward holding power to the crucible, guarantee that the outside curved surface shape of crucible is complete, can not scatter garrulous and drop, and then can prevent effectively that the crucible piece from dropping on the heat source, in addition, because the whole shape of crucible can be maintained, therefore, its inside high temperature liquid can not splash suddenly, only can follow the gap outflow that the crucible produced, because the tension effect of liquid itself, most liquid can not leak the outflow, even the condition of taking place the outflow also is according to the slow excessive in gap, operating personnel can effectively avoid with high temperature liquid's contact.

The utility model discloses in, vertical pole and down tube cooperate and are used for restricting the lateral wall position of crucible, and the sill bar is used for supporting the bottom of crucible, and the couple is used for fixing string bag structure and crucible, and vertical pole, down tube, couple and sill bar hinge dress cooperation form one can take place tensile structure, can adjust strong adaptability in certain extent according to the crucible size of co-altitude and diameter.

Detailed Description

The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.

The utility model provides a crucible is with preventing net that splits, the utility model discloses an innovation lies in, prevent that the net that splits adopts the alloy silk to make an upper side open-ended string bag structure, string bag structure suit heats simultaneously bottom the crucible and crucible under the user state.

In this embodiment, the string bag structure includes two vertical poles 4, and two vertical poles are located crucible both sides symmetry each other respectively under the suit state, two down tube 3 are all articulated to the both sides tip of two vertical poles, every down tube all is the obtuse angle with the vertical pole and extends, and two down tube tip of homonymy are connected through a connecting ring hinge dress, and four down tubes and two vertical poles form the hexagon structure, and two go-between that are located the top all make a couple 1 integrally, and the upper end of couple is used for following the dress with the crucible outward and fixes, and two go-between that are located the below make with the both sides tip of a sill bar 5 respectively integrally, the sill bar middle part undercut forms "U style of calligraphy" 6, and this sunk part's interval is not less than the external diameter of crucible bottom.

In this embodiment, the vertical rod, the diagonal rod, the bottom rod and the hook are made of alloy materials, preferably nickel-chromium alloy or iron-chromium alloy.

In this embodiment, the end face of the slanting rod at the same side as the crucible forms an arc shape, and the radian of the arc shape is matched with the radian of the outer surface of the crucible.

In this embodiment, the upper end and the lower end of each longitudinal rod are integrally formed with a closed ring, and the closed ring is hinged and fixed to the end of the diagonal rod.

The utility model discloses a working process is:

the utility model discloses during the use, as shown in fig. 1, put into the string bag structure with the crucible for the sill bar is located crucible bottom surface middle part, later hangs two couples respectively the dress and follows the position outside the crucible, makes vertical pole and down tube all be in tight state can, later can heat it and crucible simultaneously.
