Pneumatic sealing stretching sleeve of baking-casting-material-free automatic material matching system material inlet-outlet

Abstract

The present invention discloses a pneumatic sealing stretching sleeve of baking-casting-material-free automatic material matching system material inlet-outlet. According to the present invention, the gas cylinder transmission mode is more suitable for the work environment of the automatic material matching of the amorphous fire-refractory material, the gas cylinder is fixed on the outer side of the upper connection equipment material outlet and is integrally connected with the outer threads on the head portion of a gas cylinder piston rod through the inner threads of the sealing stretching sleeve, locking is performed by using a gas cylinder locking nut, the sealing ring is fixed on the material outlet flange end surface through a sealing ring connection bolt, the sealing stretching sleeve is sleeved on the outer sides of the upper connection equipment material outlet and the material outlet flange, 60 mm long and inclined chamfers are processes on the inner side at the lower end of the sealing stretching sleeve and the outer side of the material outlet flange, the included angle of the chamfer angle and the axial line is 15 DEG, and the material of the sealing ring selects a wear-resistant silicone rubber to make the 3 mm gap be left after the aligning the sealing ring and the material inlet flange, such that the upper connection equipment does not produce the interference phenomenon with the lower connection equipment during the horizontal movement process, and the sealing property is good, such that the product can be suitable for production processes of various amorphous fire-refractory materials.

Description

technical field [0001] The invention relates to the technical field of refractory material production, in particular to a pneumatically sealed telescopic sleeve for an inlet and outlet of a baking-free castable automatic batching system. Background technique [0002] In my country, refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580 ° C. Its composition is generally composed of quantitative mixing of inorganic non-metallic materials with various components. Different components need to be measured separately during production. This process is called batching. Bake-free castable is a kind of unshaped refractory material. Bake-free castable is developed on the basis of self-flowing castable combined with quick-drying technology to meet the emergency repair of various parts of industrial furnaces, fast heating and long life. The high-performance castable has an oven time of only 24 hours. Compared with conventional castab...

Problems solved by technology

However, with the advancement of science and technology, the demand for no-bake castables from all walks of life is showing a trend of diversification. The products of no-bake castables are developing in the direction of small batches and multiple varieties to meet the different needs of market segments, making no-bake castables Baking castable production enterprises are moving towards the automation of the production process, and adopt the automatic batching production line system for production. The batching process is a complicated process, which requires the coordinated operation of each production device of the batching production line. However, the current in-use equipment has about There are 20 places, all of which have the problem of unreasonable design structure. There is no seal at the inlet and outlet. After the discharge port and the feed port of the downlink equipment are aligned, the thin rubber skin is manually inserted into the feed port of the downlink equipment for batching production, which causes serious environmental pollution and high labor intensity

In addition, my country's refractory industry has repeatedly drawn up the target of the application ratio of unshaped refractory materials ≥ 50%, but due to various reasons such as technology and economy, the target of application ratio ≥ 50% has not yet been achieved, so it should be vigorously promoted. The automation and intelligence level of the production and application of shaped refractory materials, improve the quality and stability of unshaped refractory materials, reduce the production cost of high-quality unshaped refractory materials, accelerate the promotion of increasing the application ratio of unshaped refractory materials, and reach the average level of developed countries. level, further saving energy and reducing consumption
