Abstract
The invention discloses the atomization protection device that a kind of buried tube type centrifuges coating spray gun, its structure includes spraygun body, protects sleeve rear end, protects the structure such as barrel forward end, sleeve ventilating opening.The present invention devises a kind of atomization protection device of buried tube type centrifugation coating spray gun, the protection sleeve is fully utilized, solve the hardware deficiency and technical deficiency of existing buried tube type centrifugation coating, specific implementation is, the device adds the protection a being relatively large in diameter sleeve in the periphery of atomizer, so, there are enough atomization spaces between spray tip and material, coating solution atomized particle size greatly improves, coating efficiency greatly improves, coating membrane surface is brighter and cleaner, it is closely knit, coating is adhered phenomenon and seldom occurred, improve the continuity and coating quality of coating, the scope of application for being coated centrifugation is wider, relatively fine particle can be coated, enteric coating, slow control formula coating etc., barrel forward end ventilating opening is protected to ensure constant ventilation in sleeve, effectively prevent material suck-back in coating process.
Description
Technical field
The present invention relates to the atomization protection device that a kind of buried tube type centrifuges coating spray gun, more particularly, to buried tube type bag centrifugation coating spray gun, belong to medicine, chemical industry, material, food apparatus field.
Background technology
At present; in fields such as medicine, chemical industry, material, food, often using centrifugal, or dish-style; or the mode of lateral spray type coating is coated to pharmaceutical preparation product, chemical products, material science product, food etc.; and earliest art for coating, carried out using fluid bed bottom spray coating mode, and this coating mode has very high requirement to product; 1. particle size distribution range is narrow; if scope is too wide, fluidized classification is easily formed, causes to be coated heterogeneity；2. intensity requirement is high, if low intensity, under the conditions of high air quantity, high wind speed, it is easy to cause fragmentation, it is scaling-off phenomena such as；And there is also very big hardware deficiency and defective workmanship, 1. in the case where total blast volume is constant, with increasing for coating material, windage is gradually increased this coating mode, is dried air quantity and is necessarily declined, causes drying effect poor；2. in the case where total blast volume is constant, with increasing for coating material, windage is gradually increased, and is dried air quantity and is necessarily declined, cause product mobility to be deteriorated, coating is uneven；3. in the case where total blast volume is constant, as coating material increases, windage is gradually increased, and is dried air quantity and is necessarily declined, and Fluidization wind rate inevitably enlarges, and causes that coating material rate of drying is too fast, and quality of forming film is greatly reduced, and product quality can not reappear.4. coating efficiency is low；5. the production cycle is grown；6. production cost is high；In order to solve these defects of fluidized bed coating, coating form in addition arises at the historic moment, such as centrifugal, either dish-style or lateral spray type coating.
At present, it is centrifugal, or dish-style, or lateral spray type coating is that a kind of coating material utilization rate is high, the coating mode that is of wide application, main cause is that the spray gun for spraying coating material is fully embedded in material to be coated, and substantially increases the utilization rate of coating material.But just because of spray gun is fully embedded in material, the coating material of injection, in the moment for leaving nozzle, material is just touched, has so necessarily been caused：1. coating material atomization space is insufficient；2. coating solution atomized particle size is inadequate；3. the efficiency being coated does not have substantial raising；4. the surface state of coating membrane is not smooth enough；It is obvious that 5. coating is adhered phenomenon；6. less adapt to the coating of relatively fine particle.
In order to solve as above problem, different degrees of modification has all been done to respective spraygun body by equipment manufacturing enterprise, it is difficult to be fully solved the key problem of buried tube type coating.
The content of the invention
The technical problems to be solved by the invention are to overcome the hardware deficiency of existing buried tube type coating, there is provided buried tube type centrifugation coating spray gun atomization protection device a kind of reasonable in design, simple in construction, easy to use.
In order to solve the above technical problems, the present invention proposes technical scheme is：The atomization protection device of buried tube type centrifugation coating spray gun protects sleeve rear end, protection barrel forward end, sleeve ventilating opening etc. part forms by spraygun body.Spraygun body is arranged in atomization protection sleeve.Sleeve diameter 5mm-300mm is protected, the size can be adjusted according to equipment, the actual conditions of spray gun.Barrel forward end ventilating opening is protected to ensure constant ventilation in sleeve.
Compared with prior art, the present invention has advantages below：While effectively solving buried tube type coating hardware deficiency, the device, the protection a being relatively large in diameter sleeve is added in the periphery of atomizer, so, 1. there are enough atomization spaces between spray tip and material；2. coating solution atomized particle size greatly improves；3. the efficiency being coated greatly improves；4. the surface state of coating membrane is brighter and cleaner, closely knit；5. coating is adhered phenomenon and seldom occurred, the continuity and coating quality of coating are improved；6. it is suitable for the coating of relatively fine particle；7. the scope of application of this coating form is wider, such as is more suitable for special enteric coating, slow control formula coating etc..Protect barrel forward end ventilating opening to ensure constant ventilation in sleeve, effectively prevent material suck-back in coating process, can more embody the technical advantage of invention.
