Abstract
The utility model relates to a double-screw structure quantitative feeder for dry powder which is the feed device quantitatively transporting dry power in a non-lever variable way. The utility model is mainly composed of a feed part, a transmission part and a transportation part. The double-screw structure quantitative feeder for dry powder is characterized in that the big screw rod and the small screw rod of the transportation part are in the rigid connection of an axial direction; the outer edge of the vane of the small screw rod is tightly matched with a conveying pipe. A batch feeder transports the dry powder into a dissolving tank driven by a three-phase adjustable speed motor through a speed reducer drives a main shaft and the screw rod to rotate. The utility model is the special machine used in waterworks and chemical plants. The utility model has the advantages of simple structure and easy application.
Description
The utility model relates to a kind of batch charger with quantitative interpolation dry powder of double helix bar structure, belongs to the helix transporting device that is included in a kind of tubular shell, is a kind of special-purpose machinery that use in waterworks, chemical plant.
Through the Searches of Patent Literature, application number is 90204636.5, name is called the utility model of pressed powder auto feed gauging device, this device inlet point and discharging opening are all less, only be suitable for auto feed and metering in various catalyst, ignition promotor and the auxiliary agent course of conveying, its shortcoming is not to be suitable for the bigger situation of pressed powder addition, again can not continuous handling.Application number is 91217526.5, and name is called the utility model of belt-type automatic charging equipment, and its adopts the wheel shaft of the stepping motor direct drive belt charger that turns round, and its shortcoming is the toter of belt as loose unpacked material, and its antiseptic property is relatively poor.
At present, artificial acid, the alkaline powdery depurator of adding all adopted in each big waterworks of China in system water cleaning procedure, and when the workman operated, labour intensity was big, and dust is many, and work situation is poor, and the powdery depurator that adds is difficult to quantitative control.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and design a kind of can quantitatively add have acid, the powdery depurator (being commonly called as dry powder) of alkalescence but the mechanical device of continuous handling.
The utility model is made up of three parts, i.e. feeding section, running part and transport portion.Feeding section is made up of dust collecting fan, feeder and hopper; Running part is made up of buncher, retarder, coupler and main shaft; Transport portion is made up of material chamber, king bolt bar, minor spiral bar and conveying pipeline.Large and small screw rod adopts axial stiffness to connect, and the blade diameter and the pitch of large and small screw rod have nothing in common with each other, and in addition, the blade outer of minor spiral bar and the inwall of conveying pipeline closely cooperate.
The quantitative batch charger of dry powder of double helix bar structure is a kind of charging device of quantitative delivery of dry powder of stepless variable.It drives main shaft and screw rod rotation by drop-gear box, thereby dry powder is transported in the dissolving tank equably by material chamber and delivery pipe under the drive of three-phase buncher.
The utility model compared with prior art has following advantage:
1, dry powder dosage precise control, stepless variable, continuous handling, evenly reliable.
2, under operative condition, can regulate the dosage that motor speed directly changes dry powder by controller.
3, the dry powder that adds is not subjected to the influence of proportion, and can add various corrosive property dry powder.
In a word, the utility model is simple in structure, and is easy to implement.The our factory has manufactured experimently one, and when trying out in factory, the maximum dosage of dry powder is 120 liters/hour, and variable range is at 0~120 liter/hour, and result of use is good.
Accompanying drawing is the scheme drawing of the quantitative batch charger of dry powder of double helix bar structure.
Now be described further in conjunction with the accompanying drawings:
The utility model is made up of feeding section, running part and transport portion.Feeding section is made up of dust collecting fan (1), charge door (2) and hopper (3); Running part is made up of buncher (4), drop-gear box (5), coupler (6) and main shaft (7); Transport portion is made up of material chamber (11), king bolt bar (8), minor spiral bar (9) and conveying pipeline (10).Main shaft (7) and king bolt bar (8) be connected and king bolt bar (8) is that axial stiffness is connected with all adopting the way of screw thread and pin being connected of minor spiral bar (9).The blade diameter of king bolt bar (8) is greater than the blade diameter of minor spiral bar; The pitch of king bolt bar (8) is less than the pitch of minor spiral bar (9), simultaneously, and the interlobate volume ratio minor spiral bar (9) of each pitch of king bolt bar (8) big slightly.In addition, the blade outer of king bolt bar (8) is bigger with the inwall space in material chamber (11), and the inwall of the blade outer of minor spiral bar (9) and conveying pipeline (10) closely cooperates.
King bolt bar (8) can be smash the dry powder that adds pine, smash to pieces, prevents the dry powder caking, simultaneously dry powder is delivered to equably the import of conveying pipeline (10), and dry powder is enriched and does not stop up.
The blade outer of minor spiral bar (9) cooperates closely with conveying pipeline (10) inwall, and therefore the dry powder of carrying can all be pushed in the dissolving tank.Volume between minor spiral bar (9) adjacent blades is certain, thereby whenever revolves and turn around, and the dry powder amount of conveying also is certain, so the rotating speed by buncher adjustable screw bar just can reach the purpose of quantitative delivery of dry powder.
Working process of the present utility model is as follows:
The starting dust collecting fan adds material bin (3) with dry powder by charge door (2), and the dust of kicking up when reinforced is discharged by dust collecting fan (3); Connect the source switch of motor, buncher (4) rotates, slow down through drop-gear box (5), coupler (6) drives main shaft (7) and rotates, at this moment, dry powder falls into material chamber (11) by hopper (3), and main shaft (7) drives king bolt bar (8) and minor spiral bar (9) rotates, the blade of king bolt bar (8) is delivered to conveying pipeline (10) inflow point with dry powder, and the blade by minor spiral bar (9) pushes dry powder in the dissolving tank along conveying pipeline (10) again.
Claims (1)
1, a kind of quantitative batch charger of dry powder of double helix bar structure, it is by feeding section, running part and transport portion are formed, it is characterized in that transport portion is by material chamber (11), king bolt bar (8), minor spiral bar (9) and conveying pipeline (10) are formed, main shaft (7) and king bolt bar (8) be connected and king bolt bar (8) connects with all adopting axial stiffness being connected of minor spiral bar (9), the blade diameter of king bolt bar (8) is greater than the blade diameter of minor spiral bar (9), the interlobate volume ratio minor spiral bar (9) of each pitch of king bolt bar (8) big slightly, the blade outer of minor spiral bar (9) and conveying pipeline (10) closely cooperate.
