Abstract
A quantitative filling control device for powdery solid, which comprises a container (1) which is provided with a feeding hole [6] and a discharge hole (4), and a spiral conveying mechanism, wherein an interlayer (3) is arranged between the feeding inlet (6) and the discharge port (4), and a through hole (8) is arranged on the interlayer (3); the screw rod (5) of the spiral conveying mechanism is matched with the through hole (8). The utility model has the advantages of simple and convenient operation and high accuracy, and is suitable for the filling of powdery solid in industrial production, and especially for micro quantitative filling.
Description
Technical field
The utility model relates to a kind of quantitative filling apparatus, is a kind of pulverulent solids control device of quantitatively annotating specifically.
Background technology
Quantitatively the device of filling aspect is a lot of at present, as Chinese patent 200420056224.6,200720072607.6 or the like.Their quantitative filling all is under the effect of hydraulic pressure or air pressure mechanism, liquid quantitative is injected, so these devices uses when only being fit to filling liquid.
In industrial production, particularly in Chemical Manufacture, according to the condition of production, whenever necessary, will annotate the at regular time and quantity additive of pulverulent solids or catalyst etc., because addition is fewer, common way is that the charge pipe of additive or catalyst is installed on pipeline or equipment, sealing mechanism is installed on the mouth of pipe, opens sealing mechanism during use again by manually additive or catalyst quantitatively being added.
For some devices that need under air-proof condition, move, as the polypropylene process units, adopt this method to inject, air can be sneaked in it when operation, to all influences to some extent of quality of security in the production process and product.And this method troublesome poeration, not high for an accuracy of slightly quantitatively annotating, the needs of incompatibility modern enterprise production development.
Summary of the invention
The purpose of this utility model provides a kind of pulverulent solids easy to operate, accurate measurement of annotating control device of quantitatively annotating, and helps guaranteeing the security of production process and the quality of product.
To achieve the above object, the technical solution adopted in the utility model is:
A kind of pulverulent solids control device of quantitatively annotating comprises a container and a screw conveyer structure that charging aperture, discharging opening are installed, between charging aperture and discharging opening interlayer is arranged, and has through hole on the interlayer, and the screw rod of screw conveyer structure cooperates with through hole.
The material guide mechanism that cooperates with the screw conveyer structure is arranged in the described container.
Described material guide mechanism is one to be sleeved on the cone of screw rod outside, and the big end of cone is connected with container in the above, and the small end of cone is connected with the interlayer upper surface below.
Termination electric control driving device on the screw rod of described screw conveyer structure, electric control driving device is installed in the container upper end face.
Like this, discharging opening in the utility model can be connected with the charge pipe of installation additive on pipeline or the equipment or catalyst, by electric control driving device control screw speed, realize quantitatively filling, because this filling can guarantee to carry out under air-proof condition, avoid air to sneak into, help improving the security in the production process and the quality of product.The utility model is simple to operation, the accuracy height.It is suitable for pulverulent solids filling in the industrial production, particularly little quantitative filling.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the A part enlarged drawing of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of pulverulent solids control device of quantitatively annotating, comprise a container 1 and a screw conveyer structure that charging aperture 6, discharging opening 4 are installed, the main body of container 1 is a vertical and cylindrical, and charging aperture 6 is connected on the cover plate above the container 1, and discharging opening 4 is connected on below the container 1, between charging aperture 6 and discharging opening 4, interlayer 3 is arranged, interlayer has through hole 8 on 3 middle parts, and the screw rod 5 of screw conveyer structure cooperates with through hole 8, sees Fig. 2.
For the pulverulent solids that makes 1 li in container in use, but automatic stream through hole 8 places, described container has the material guide mechanism that cooperates with the screw conveyer structure for 1 li, material guide mechanism is one to be sleeved on the cone 2 of screw rod outside, the big end of cone 2 is connected with container 1 inwall in the above, the small end of cone 2 is connected with interlayer 3 upper surfaces below, and the portlet of cone 2 is more bigger than through hole 8 apertures.
Termination electric control driving device 7 on the screw rod 5 of described screw conveyer structure, electric control driving device 7 are installed in container 1 upper surface.
The filling control device that the utility model adopts following technical parameter to make is on probation, respond well through the polypropylene process units at 5000 tons/year.
Container diameter is selected 260mm, container 1 body height 800mm (being between interlayer 3 and container 1 upper end), and it is 18mm that screw mandrel is selected diameter for use, and pitch is 10mm, and electric control driving device 7 is selected the single phase ac torque motor for use, controls by control circuit.During use, when electric control driving device 7 rotated, the output shaft that screw rod is followed electric control driving device 7 rotated together, and screw rod 5 axle center are motionless, and screw rod is brought the solid powder substance of the inside in the container 1 into by through hole 8 and screw rod 5 inside grooves like this.Screw rod 5 inside grooves are made semicircle, guarantee that blanking is even, and interior groove radius is 5mm.
