Description
Technical Field
The invention relates to a powder coating anti-sticking steel belt granulator, and belongs to the field of granulators.
Background
The steel belt granulator uniformly distributes hot melt materials in an upstream procedure on a steel belt moving at a constant speed below the granulator through a distributor of the granulator, and a continuous water spraying and cooling device is arranged below the steel belt to force the materials on the steel belt to be rapidly solidified and cooled in the moving process, so that the aim of granulation and forming is fulfilled. The material distributor forms of the granulator with different principles such as external rotation type, internal rotation type, reciprocating type, gate type and the like can be selected according to physical properties and process requirements. According to physical properties and use requirements, cloth forms such as intermittent dropping, continuous strip discharging, full-width overflow and the like can be selected to respectively produce hemispherical products, strip-shaped products and sheet-shaped products.
In the cooling process, water can absorb a large amount of heat and the temperature rises fast, and heat exchange efficiency reduces, can not play fine cooling effect to the material that part melting point is low, and the material is still in semi-solid state at the discharge end, leads to being stained with material and blanking difficulty to easy adhesion and deformation after the granule falls. The discharge end department usually can set up the scraping plate and be used for scraping the granule, but the scraping plate is usually fixed to the angle is also fixed, can cause very big resistance to the steel band when scraping to certain granule that bonds firmly with the steel band, increases the energy consumption. In addition, the scraper can cause scratches on the steel strip after long-time operation.

According to the defects in the prior art, the technical problems to be solved by the invention are as follows: the utility model provides a dusting anti-sticking material steel band granulator, the granule falls on the powder, and the powder is with granule and steel band separation, avoids the granule to bond on the steel band, and the powder can not fix on the steel band simultaneously, need not the clearance, and the powder can also recycle simultaneously.
The powder-coated anti-sticking material steel belt granulator comprises a rack, wherein a driving roller and a driven roller are respectively arranged on two sides of the rack, an annular steel belt is wound on the driving roller and the driven roller, a powder attaching device and a water mist device are arranged below the steel belt, a powder recovery device is arranged at the discharge end of the steel belt, a sliding material groove is arranged at the discharge end of the steel belt, the feed end of the sliding material groove is positioned below the discharge end of the steel belt, and a granulation device is arranged above the steel belt;
the powder attaching device comprises an inverted cone shell-shaped containing cavity, the containing cavity is fixed on the base through a vertical rod, the upper end of the containing cavity is open, the edge of the upper end of the containing cavity is close to the steel strip, an air faucet is arranged at the bottom of the containing cavity and connected with an air source, and powder is placed in the containing cavity.
The water mist device is arranged in front of the powder attaching device and comprises a water mist generator, a gas collecting hood is arranged above the water mist generator, and the upper edge of the gas collecting hood is close to the steel strip.
The principle and the process are as follows:
when the device works, the driving roll drives the steel belt to rotate. The water mist generator generates water mist, and the water mist is sprayed to the steel belt. The steel belt granulator is provided with a spray cooling system, and the steel belt has a certain temperature, so that water mist can be uniformly attached to the steel belt to form compact micro water drops. The air nozzle blows air into the containing cavity to blow powder, the powder is dispersed in the containing cavity, and the powder is combined with water drops when meeting the small water drops attached to the steel strip. The granule that prilling granulator fell falls on the steel band, because adhere to the one deck powder between granule and the steel band, the granule just can not bond on glossy steel band like this, and the steel band need not clear up, also need not the scraper blade, has avoided the damage of steel band, increase of service life, reduction equipment cost. The particles fall on the chute when moving to the discharge end.
The drying device is arranged in front of the granulating device and located above the steel belt in a horizontal position, the drying device comprises an electric heating tube, the electric heating tube is fixed on the energy-gathering cover, the energy-gathering cover is fixed on the machine frame, the lower surface of the energy-gathering cover reflects light, and the electric heating tube is close to the steel belt.

When powder is needed to be added, the powder can be directly added into the collecting hopper.
The inner wall of the gas pipe is distributed and fixed with small upright posts, and the distribution density of the small upright posts is gradually increased from the gas inlet end to the gas outlet end. Because the powder can take place the phenomenon of hardening with the inevitable meeting of water droplet contact, the powder that hardens can constantly touch little stand and is broken up by little stand at the in-process that is blown by the air current so, and the distribution density of little stand can prevent that the piece that hardens from blockking up at the inlet end from inlet end to giving vent to anger the end gradual increase, and the little stand density of inlet end can make things convenient for the piece that hardens to pass through more to make things convenient for it to break up.
One side of the opening at the lower part of the collecting hopper close to the fan is lower than the opposite side. Like this the air current is by diminishing greatly in one side that collection fill lower part opening is close to the fan, forms the negative pressure, can suck away the powder, avoids the air current to get into to collect to fight and blow up the powder, avoids extravagant and dust pollution, also need not to use the powder pump, saves equipment cost.
And sieve pores are arranged on the chute, and the pore diameter of the sieve pores is smaller than the diameter of the particles. When the particles fall on the sliding chute, the redundant powder attached to the particles due to inertia can be brushed off due to inertia, and falls into the collecting hopper through the sieve holes, so that the waste of the powder is avoided.
Compared with the prior art, the invention has the beneficial effects that:
according to the powder-coated anti-sticking material steel belt granulator, the water mist generator generates water mist, and the water mist is sprayed onto a steel belt.
