Abstract
The invention relates to a multi-spiral high-precision quantitative feeding device, which comprises a base, wherein a motor is sequentially connected with a gearcase on the base through a speed reducer; and one end of a spiral feeding mechanism arranged at the lower part of a feeding case is connected with a driving shaft in the gearcase, and the other end of the spiral feeding mechanism extends into a discharging mechanism. The multi-spiral high-precision quantitative feeding device is characterized in that at least three spiral rods are arranged in the spiral feeding mechanism in parallel, spiral blades of the spiral rods are consistent in spiral angle and diameter, and every two adjacent spiral rods are different in rotating direction and are embedded to each other. According to the invention, five spiral rods are arranged in the spiral feeding mechanism in parallel. The multi-spiral high-precision quantitative feeding device has the beneficial effects that a dry powder agent with unchanged dosage is conveyed after being distributed to a plurality of spiral rods, so that the powder agent in a storage bin can be prevented from being crosslinked and the problems of uneven feeding, even no feeding and the like are solved, and therefore high-precision quantitative feeding of the dry powder agent is achieved.
Description
Technical field
The present invention's design relates to a kind of powder or particulate material load transfer device.
Background technology
Configure and add as the important means of water technology with various dry powder, very consequence is arranged in whole water treatment procedure.Be widely used in municipal water supply and sewage disposal, be applicable to simultaneously the industries such as oil, chemical industry, papermaking, electric power, coal, pharmacy, food.Dry powder pharmaceutical adds the common technology method at present two kinds; A kind of is that wet method adds, and is about to dry powder pharmaceutical and is configured to the finite concentration slurries, is added to the use point by measuring pump; Another kind is that dry method adds, be about to dry powder pharmaceutical by the discharging of dosing equipment to water sprayer, by water sprayer with the dry powder pharmaceutical dissolving and be transported to the place to use.
These two kinds of processes all need to use dosing system to carry out powder medicine quantitatively to carry.Commonly used dosing system mainly forms quantitative transfer member by one or two screw rods in the prior art.When one or two screw rods rotate in feed bin, because the screw rod circular movement, dry powder pharmaceutical easily occurs and put up a bridge to stop up and form feed bin cavity situation, this phenomenon also is " frame canopy ", thereby causes occurring that blanking is inhomogeneous, the problem such as blanking not even.Because it is inaccurate to throw in the quantity of dry powder pharmaceutical, can have a strong impact on the quality of water treatment.
Summary of the invention
In order to overcome the technological deficiency of above-mentioned existing dosing system, the present invention proposes following technical scheme: a kind of many spirals high-precision quantitative charging gear, comprise base, and motor through retarder at the base gear case that is linked in sequence.The imput shaft that is arranged in an end and the gear case of spiral feeding mechanism of feeder lower box part is connected, and the other end stretches in the discharging mechanism.Its feature is: in the spiral feeding mechanism parallel installation screw rod quantity be at least 3, the helicallobe spiral angle of this screw rod and blade diameter is consistent, the rotation direction of adjacent spiral opposite and mutually embed.In the spiral feeding mechanism of the present invention parallel installation screw rod quantity be 5.Described motor is variable-frequency motor.Be provided with gear, bearing and sealing arrangement in the gear case.
Adopt the beneficial effect of many spirals high-precision quantitative charging gear of above technical scheme to be: in the constant situation of dry powder pharmaceutical dosage, dosage is assigned at least 3 screw rods to be carried, can avoid the feed bin powder medicine to occur putting up a bridge, avoid that blanking is inhomogeneous, the problem such as blanking not even, thereby realize the high-precision quantitative input of dry powder pharmaceutical.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
Fig. 1 shows the situation that is made of quantitative transfer member one or two screw rods.One or two screw rods 6 are when the 5 interior rotation of feed cabinet, because screw rod 6 in the course of the work self cleaning is bonded at powder on the flight, the dry powder pharmaceutical bridging easily occurs and form feed bin cavity 11, this phenomenon also is " frame canopy ", thereby causes occurring that blanking is inhomogeneous, the problem such as blanking not even.Because it is inaccurate to throw in the quantity of dry powder pharmaceutical, can have a strong impact on the quality of water treatment.
Fig. 2 is for being many spirals of the present invention high-precision quantitative charging gear schematic diagram, the rotation direction of the helicallobe spiral angle of this spiral feeding mechanism and consistent, the adjacent screw rod 6 of blade diameter is opposite and mutually embed a part, and self cleaning is bonded at the powder on the flight in the course of the work.Dry powder pharmaceutical is evenly distributed on the many pressure feeding spirals 6 pushed.
Can find out from Fig. 3 and Fig. 4, dry powder pharmaceutical enters dosing system by feed cabinet 5, under the drive of pressure feeding spiral bar 6 by the main shaft in the variable-frequency motor 2, retarder 3 and the gear case 4 that are arranged on the base 1, does circular-rotation.In gear case 4, be provided with gear 8, bearing 9, sealing arrangement 10.Powder medicine can be realized quantitatively being transported to feed box 7 under the drive of pressure feeding spiral 6, is added to specify to use point.And because many spirals turn round simultaneously, because the helicallobe of pressure feeding spiral 6 is through calculating, and angle and size are fixing, adjacent rotary orientation is opposite and embed mutually a part, self cleaning is bonded at the powder on the flight in the course of the work, effectively avoids the interior powder medicine put up a bridge " frame canopy " that occurs of feed cabinet 5.Thereby realize the high-precision quantitative input of dry powder pharmaceutical.
