Abstract
The utility model discloses a diffusion furnace-boat head. The diffusion furnace-boat head comprises a base board and a boat head and is characterized in that the boat head is arranged in the middle of the base board, and the diffusion furnace-boat head further comprises set screws which are symmetrically arranged on the left side of the boat head and the right head of the boat head. Compared with the prior art, the boat head of the diffusion furnace-boat head is additionally provided with the set screws, so that a phenomenon that diffusion furnace paddles which are arranged inside the boat head deviate in a left and right mode is avoided, device production stability is improved, failure frequency is effectively reduced, and device failure time is effectively shortened.
Description
Technical field
The utility model relates to a kind of diffusion furnace-boat head.
Background technology
The boat head of seven-star soft landing diffusion furnace (L4511 II-26/ZM) equipment can not be completely fixed position, the oar left and right sides, in the long-term production process because during loading and unloading quartz boat (diffusion furnace frock) and quartz boat turnover boiler tube to the certain active force of oar generation, because the spindle nose position does not have left and right sides positioner, so the position of oar is offset about taking place often, cause carriage damage, quartz boat to damage and then produce fragment.
The utility model content
The utility model purpose:The purpose of this utility model is exactly at the deficiency in the present technology, and a kind of diffusion furnace-boat head is provided.
Technical scheme:The technical solution of the utility model is as follows:
A kind of diffusion furnace-boat head, it comprises base plate and boat head, it is characterized in that: described boat head is installed on described base plate middle part, and it also comprises fixed screw, and described fixed screw symmetry is installed on the described boat head left and right sides.Increased fixed screw about the boat head, thereby avoided in use, the skew of position, the left and right sides takes place in the diffusion furnace oar that is installed on boat head inside.
The rarest two pairs of described fixed screw.
Described boat head inside is provided with a cuboid hole of running through before and after it.
Operation principle:In the diffusion furnace running, if boat head position does not have left and right sides positioner, skew about the position of oar takes place often so, therefore, the present invention has increased fixed screw about the boat head, thereby has avoided in use, and the skew of position, the left and right sides takes place the diffusion furnace oar that is installed on boat head inside.
Beneficial effect:Adopt the following advantage that the utlity model has of technique scheme: after increasing set screw about the boat head, the positional stability that is installed on the oar of boat head inside improves greatly, the position shift phenomenon reduces greatly, effectively reduce the number of stoppages and equipment fault time, avoided the skew of oar position to cause that carriage damages, quartz boat damages and the problem of the fragment that produces.
Description of drawings
Fig. 1 is the vertical view of the utility model embodiment;
Fig. 2 is the side view of the utility model embodiment;
Fig. 3 is the front view of this practical new embodiment;
Fig. 4 is the stereogram of this practical new embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in drawings, this practical new a kind of diffusion furnace-boat head, it comprises base plate 1 and boat head 2, and is described
In the instrument running, after slurry is installed on boat head 2 inside, because the effect of fixed screw 3, thereby avoided oar that the skew of position, the left and right sides takes place, improve device fabrication stability, effectively reduced the number of stoppages and equipment fault time.
The above only is of the present utility model preferred embodiment a kind of; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection of the present utility model.
Claims (3)
1. one kind spreads the furnace-boat head, it comprises base plate (1) and boat head (2), it is characterized in that: described boat head (2) is installed on described base plate (1) middle part, and it also comprises fixed screw (3), and described fixed screw (3) symmetry is installed on described boat head (2) left and right sides.
