Abstract
The utility model relates to a negative-pressure pneumatic conveying device for the material of a spray drying tower, which belongs to the fields of the transport and the production of a dried material, in particular to a device for transporting a powdery material obtained by drying through a spray drying tower. The negative-pressure pneumatic conveying device for the material of the spray drying tower comprises a material receiver, a cyclone, a vibrating sieve and a fan. The negative-pressure pneumatic conveying device for the material of the spray drying tower is characterized in that when the fan runs, the inside of the cyclone is caused to be in a negative-pressure state, and the material in the material receiver is adsorbed by a pipeline to enter the cyclone; and after the material is separated, heavy powder enters the vibrating sieve from an outlet at the bottom end of the cyclone, and fine powder enters the drying tower through the fan. The utility model achieves the aims that the material is pneumatically conveyed, the pollution caused by the contact of the material and air is avoided, the loss of the powder also does not occur, and the wall of the tower is swept.
Description
Technical field
The utility model belongs to dried material and transports production field, is specially the device that transports through the dry granular material that obtains of spray drying tower.
Background technology
Spray drying tower is as material drying device, in the production of enterprises such as food, medicine, be widely used, but in process of production, because the spray drying tower tower body is bigger, and discharging opening is overhead lower, be difficult in the spray drying tower discharging opening and directly carry out material package, and avoid contacting and cause the germ contamination material with air.If the installation kit installing is executed and packed under tower body, then be unfavorable for the cleaning of spray drying tower.Enter material in order to reduce airborne bacterium, and do not influence the cleaning of spray drying tower, need a kind of device that material is transported out from the tower discharging opening, enter desinfection chamber and pack.
The utility model content
The technical problems to be solved in the utility model is: this design avoids material to contact the pollution that causes with air, and fine powder race powder phenomenon, and fan outlet is connected with drying tower, can reach the purpose of cleaning drying tower inwall.
The technical scheme that its technical problem that solves the utility model adopts is: this spray drying tower material negative pressure is offered device as a gift, comprise: spray drying tower, the material receiver that movably has air cleaner, Asta-3746, vibratory sieve, feed bin, blower fan, the spray drying tower discharging opening is connected with the material receiver that movably has air cleaner, can avoid material to contact the secondary pollution that causes material with air like this, the import of Asta-3746 connects the material receiver, the top outlet connects the air inlet of blower fan, the bottom outlet connects vibratory sieve, the air outlet of blower fan is connected the feeding drying tower with tower body, when blower fan turns round, in the Asta-3746 is negative pressure, at this moment the material in the sorption material receiver enters Asta-3746, heavy powder enters vibratory sieve from the bottom outlet after the feed separation, sieve and laggardly go into feed bin and pack, the fine powder that is come out by Asta-3746 enters drying tower by fan outlet, reaches both to avoid fine powder to run powder, the purpose that can clean the drying tower inwall again.
Operation principle is: when blower fan turns round, because making, the exhausting of blower fan forms negative pressure in the Asta-3746, the interior material of material receiver that sorption movably has air cleaner enters Asta-3746, after material separates in Asta-3746, heavy powder enters vibratory sieve from the bottom outlet, then enter feed bin, fine powder is exported out to carry by the blower fan top and enters drying tower.
Description of drawings is installed a material receiver that movably has air cleaner at the spray drying tower material outlet
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment, wherein: 1 spray drying tower, 2 drying tower discharging openings, 3 movably have the material receiver of air cleaner, 4 Asta-3746s, 5 vibratory sieves, 6 feed bins, 7 fans entrances, 8 blower fans, the outlet of 9 blower fans.
The specific embodiment
The utility model is described in further detail in conjunction with Fig. 1:
As scheme shown in Figure 1: the material negative pressure wind send device to be made up of the material receiver 3 that movably has air cleaner, Asta-3746 4, blower fan 8.When blower fan turns round, take out the wind in the Asta-3746, making Asta-3746 interior is negative pressure, enters Asta-3746 4 by the materials in the tube connector sorption material receiver 3, under action of centrifugal force, heavy powder sinks, enter feed bin 6 by vibratory sieve 5, and fine powder enters blower fan 8 by the outlet of Asta-3746 top, enters drying tower again, both reaching, wind send material to avoid fine powder to run powder, the purpose of cleaning the tower wall again.
