Background technology
The quartz melting first time that stove is mainly used in environmental protection class opticglass and lanthanide optical glass of getting the raw materials ready is got the raw materials ready, and solves the problems such as painted, photosensitiveness fluctuation that opticglass is once changed strip.It uses Si-Mo rod as heating material, working temperature is between 1100 ℃～1500 ℃, use the quartzy crucible of bottom opening as getting the raw materials ready container, crucible bottom outlet during work (leaking the material mouth) need block up, and the raw material melting finishes also and to want can be very convenient must mouthful to emit from leaking material, and movable water plug has been exactly to stop up the effect of leaking the material mouth at the bottom of the quartzy crucible.
At present, be used for the quartzy stove of getting the raw materials ready the leak stopping of leakage material mouth the water plug as shown in Figure 1, the water plug comprises the water plug body 4 of axial hollow, closed at both ends, is arranged on water inlet pipe 6 and rising pipe 5 on these water plug body 4 lower surfaces, the upper surface of water plug body 4 is the plane.Flat water plug is by the snap-in force of spring, make water beyond the Great Wall end face be close to quartzy crucible bottom surface, thereby stop up the leakage material mouth 1 of quartzy crucible 3, finishing when the raw material fusing needs when leaking material mouthful 1 and emit, the water plug is removed, glass metal 2 flows out from leaking material mouthful 1.This flat water plug is a kind of contact with contacting at the bottom of the quartzy crucible, thereby quartzy crucible 3 is had certain cooling performance.When quartzy crucible 3 is worked, the temperature of crucible and glass metal reaches more than 1,000 degree Celsius, and at the bottom of the crucible with flat water plug contact part because the cooling effect of water plug makes its local temperature on the low side, when being subjected to the erosion of high temp glass liquid, often burst, damage quartzy crucible 3, the seepage phenomenon happens occasionally at the bottom of causing crucible, thereby influences production efficiency, increases production cost.
Summary of the invention
Purpose of the present invention is exactly to provide at above-mentioned weak point a kind of and had both satisfied the quartz stove of getting the raw materials ready and produce needs, can effectively protect quartzy crucible again, and the quartzy crucible that can reduce production costs, the enhance productivity stove of getting the raw materials ready leaks material saliva plug.
Technical solution of the present invention is: a kind of quartzy crucible stove of getting the raw materials ready leaks material saliva plug, comprise water plug body and the water inlet pipe and the rising pipe that are arranged on this water plug body lower surface, it is characterized in that: the conical surface that the upper surface of described water plug body is and leakage material mouth cooperates.
The conical surface angle of the upper surface of the water plug body described in the technology of the present invention solution is between 110 °-130 °.
Water plug body described in the technology of the present invention solution adopts heat-resistance stainless steel to make.
This body diameter of water plug described in the technology of the present invention solution is φ 36-φ 45mm, and wall thickness is not less than 3.5mm, and upper surface thickness is not less than 4mm.
Rising pipe upper port described in the technology of the present invention solution is higher than water inlet pipe upper port 8mm-12mm.
The present invention is owing to the upper surface with water plug body is designed to the conical surface, thereby when the quartzy crucible of obstruction is got the raw materials ready stove leakage material mouth, it is the line contact that water plug body upper surface contacts with leakage material mouth, contact area is very little, avoided existing water plug body upper end to contact the deficiency that exists with quartzy crucible baseplane, therefore the heat of the quartzy crucible of taking away by water plug and water coolant is also very little, and reason part (leak at the bottom of the crucible material mouthful) temperature difference is big and burst in the course of the work to make quartzy crucible, prolongs the work-ing life of quartzy crucible greatly.Owing to adopt the taper upper surface, thereby water plug body diameter is reduced, thereby reduce the volume of water plug body, the corresponding cost that reduced.Of the present invention coming into operation not only saved production cost, also reaches the purpose of enhancing productivity because of the maintenance and inspection time indirect that reduces quartzy crucible.The present invention has and both satisfies the quartz stove of getting the raw materials ready and produce needs; can effectively protect quartzy crucible again; and the characteristics that can reduce production costs, enhance productivity, be mainly used in quartzy crucible leaks material mouthful when preparing environmental protection class opticglass or lanthanide optical glass raw material at the bottom of the crucible leak stopping.
