Abstract

The utility model relates to a split-type crucible for burning or reducing fluorescent powder. The technical problem to be solved is that the crucible has the characteristics of lager power volume and convenience for powder emptying; when the crucible is partially damaged, the whole crucible is unnecessary to be changed so as to lower the production cost. The split-type crucible adopts the technical scheme that the split-type crucible comprises a crucible cover and a crucible body; and the split-type crucible is characterized in that the crucible body is cylindrical, and the crucible body is formed by sheathing the tubular crucible body and a crucible base. The crucible base is horizontally arranged; the upper surface of the crucible base is provided with a locating ring which protrudes upwards; and the outer diameter of the locating ring is adapted to the inner diameter of the crucible body.

Description

Split type crucible

Technical field

The utility model relates to a kind of crucible, especially for the split type crucible of fluorescent material calcination or reduction.

Background technology

In the preparation process of fluorescent material, generally adopt the container of crucible as fluorescent material calcination or reduction operation.What adopt usually is conical crucible, comprises crucible cover and conical crucible body; The defective of this type of crucible is: the volume of crucible is less, and promptly the filling amount of crucible is less, can only process less fluorescent material at every turn, and production efficiency has much room for improvement; Secondly, after machining, the sticking powder in crucible middle and lower part is serious, and must use aid to beat the outer wall of crucible body could be clean with powder, and powder is comparatively inconvenient; In addition, breakage anywhere appears in this type of crucible, whole crucible all must be changed, and cost is higher.

The utility model content

The purpose of this utility model is to overcome the problems referred to above that exist in the background technology, a kind of improvement of crucible is provided, this crucible should have filling amount big, fall powder characteristics easily, and when crucible is local when breakage occurring, need not to change whole crucible, to reduce production costs.

The technical scheme that the utility model proposes is:

Split type crucible comprises crucible cover and crucible body; It is characterized in that: described crucible body is a cylindrical shape, and this crucible body is socketed to form at the bottom of by tubulose crucible body and crucible.

Horizontally disposed at the bottom of the described crucible, its upper surface is shaped on the up outstanding locating ring of a circle, and the internal diameter of the external diameter of this locating ring and crucible body adapts.

The beneficial effects of the utility model are: the form of the utility model by making up with the crucible body at the bottom of the crucible, and the powder problem is glued in the bottom of a pan that has solved conventional conical crucible preferably; In the utility model, the crucible body is the bigger cylindrical shape of volume, and the more conical crucible of filling amount has more about 1/3rd, and production efficiency is significantly improved; And when at the bottom of the crucible body of crucible or the crucible when damaged, only need to change damaged part, need not to change whole crucible, saved production cost.In addition, the utility model is simple in structure, and is easy to use, and production cost is lower, makes also more or less freely.

Fig. 1 is a main TV structure schematic diagram of the present utility model.

Fig. 2 is a decomposition texture schematic diagram of the present utility model.

Fig. 3 is the plan structure schematic diagram at the bottom of the crucible in the utility model.

The specific embodiment

Below, the technical solution of the utility model is described further by Figure of description.

As shown in Figure 1 and Figure 2, split type crucible described in the utility model comprises crucible cover 1 and crucible body; Described crucible body is a cylindrical shape, and diameter is according to determining according to the actual production demand, and this crucible body 3 is socketed to form at the bottom of by the crucible of a tubulose crucible body 2 and a circle.

As Fig. 1, shown in Figure 3, described crucible bottom is horizontally disposed, and its upper surface is made the up outstanding locating ring 3-1 (axis normal of locating ring is at the bottom of crucible) of a circle, and the internal diameter of the external diameter of this locating ring and crucible body adapts, crucible body vertical sleeve can be realized the installation of crucible body on this locating ring.

Use principle of the present utility model is:

During production, be enclosed within the crucible body at the bottom of the crucible on (horizontally disposed at the bottom of the crucible), form a cavity that holds fluorescent material, the fluorescent material semi-finished product are packed in this cavity, cover crucible cover, crucible can be pushed then to carry out pyroreaction in the tunnel burner hearth and handle; After reaction is finished, open crucible cover, fluorescent material can be poured out, if crucible bottom is residual fluorescent material arranged, can will pull down at the bottom of the crucible, the powder of bottom can easily be poured out.

Claims

1. split type crucible comprises crucible cover (1) and crucible body (2); It is characterized in that: described crucible body is a cylindrical shape, this crucible body by tubulose crucible body and crucible at the bottom of (3) be socketed to form.

2. split type crucible according to claim 1 is characterized in that: (3) are horizontally disposed at the bottom of the described crucible, and its upper surface is shaped on the up outstanding locating ring (3-1) of a circle, and the internal diameter of the external diameter of this locating ring and crucible body (2) adapts.
