Abstract
A powder cascade type cooling device comprises a receiving hopper, wherein a cooling barrel is connected under the outlet of the receiving hopper, a circulating cooling system is arranged on the wall of the cooling barrel, a group of cooling tubes which are arrayed in a barrier shape is horizontally arranged on the upper part of the cooling barrel, and a quartz glass sleeve is respectively sleeved outside each cooling tube in a sliding mode; and a sudden cooling disc is connected under the cooling barrel, a gas collecting barrel is connected under the sudden cooling disc, the sudden cooling disc is provided with a through hole which is connected with the cooling barrel, and jet flow pores are formed on the wall of the through hole along the tangential direction. High-temperature dried powder continuously falls into the receiving hopper to impact the quartz glass sleeves, is subjected to primary scattering and cooling, is fed into a cooling area in the cooling barrel and is subjected to accelerated cooling through high-velocity air flow after entering the sudden cooling disc; and after three levels of cascade cooling, materials are maintained below 40 DEG C to fall into receiving quartz glass containers. The powder cascade type cooling device is simple in structure, has high cooling velocity and high efficiency and cannot generate secondary pollution.
Description
Technical field
The utility model relates to a kind of high purity quartz material preparation technology, particularly a kind of powder Cascade refrigerating unit.
Background technology
From entering 21 century, the microelectronics industry of China, photovoltaic industry, national defense industry and relevant new high-tech enterprise are flourish, the annual growth rate that has even surpass 50%.And as basic, supportive and guiding high purity quartz material preparation technology are monopolized by the U.S., France and a few countries such as Russian for a long time, and its high-end product is limited import, and the Sustainable development of China's new and high technology is faced with severe challenge.
It is exactly the equipment special scarcity that China explores the key bottleneck that the extraction glass sand runs into from natural vein quartz ore for many years.If natural vein quartz ore is purified, a requisite procedure adopts chemical method exactly, and the chemical method purifying technique be unable to do without the operations such as washing, oven dry and cooling, and oven dry is the highest link of frequency of utilization in the complete processing of glass sand.The technological temperature of glass sand is generally selected between 200 ℃ ~ 1200 ℃, must be cooled to just can detect packing below 40 ℃ according to processing requirement high-temperature material.Traditional way all is to take naturally cooling.Natural cooling is not only time-consuming, and also can roll up secondary pollution in this process, causes quality of products.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, has proposed a kind of powder Cascade refrigerating unit of realizing the pollution-free quick cooling of high-temperature material.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of powder Cascade refrigerating unit, be characterized in: be provided with receiving hopper, below the receiving hopper outlet, be connected with cooling cylinder, the barrel of cooling cylinder is provided with circulating cooling system, is provided with on cooling cylinder top to be horizontally disposed one group of cooling tube of arranging by paliform, and the two ends of cooling tube communicate with water coolant, all be set with quartz glass sleeve outside every cooling tube, quartz glass sleeve and cooling tube are slidingly matched; The below of cooling cylinder and quenching dish join, and quenching dish below is connected with gas cylinder, and described quenching dish is provided with the through hole that joins with cooling cylinder, is provided with the jet pore along the hole tangential direction on the hole wall of through hole.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further described circulating cooling system comprises the circulation chamber on the barrel that is arranged on cooling cylinder that the circulation chamber joins with circulation liquid-inlet pipe, circulation drain pipe respectively.
The technical problems to be solved in the utility model can also come further to realize that described jet pore is provided with two by the following technical programs, along the hole wall of through hole in the same way, be symmetrical arranged.
The technical problems to be solved in the utility model can also be come to realize that further described jet hole diameter is 2 ~ 4mm by the following technical programs.
Powder through high temperature drying falls into receiving hopper continuously, and impact is in the quartz glass sleeve of the state of cooling and slip, powder is through tentatively breaing up cooling, entering cooling zone in the cooling cylinder from the passage between the adjacent quartz glass sleeve again, when powder enters the quenching dish, immediately by at a high speed and be the air-flow that tangent line enters and accelerate cooling.After above-mentioned three sections tandems cooling, the state that material will remain on less than 40 ℃ falls in the quartz container that connects material.The utility model compared with prior art, and is simple in structure, and feeding is easy, with low cost, easy to use, neither needs complicated electric elements control, also need not accurate match mechanism.Cooling range is wide, can be used for any material cooling of 200 ℃ ~ 1200 ℃.Speed of cooling is fast, and efficient is high, and quality is good.Whole process of cooling is less than 1 second, and the cooling uniformity to material is good simultaneously, the process of cooling continuity.Process of cooling does not produce any pollution to material.This device is without abrasion piece, and the operation and maintenance cost is low.
