Abstract
The utility model provides a powdery material flow control device, is equipped with the casing of a vertical setting, and the upper portion of casing is the pan feeding mouth, and the lower part of casing is the discharge gate, is located the inside fixed unloading ring of casing of pan feeding mouth department, and the below of unloading ring is equipped with and the spherical or conical restriction piece of unloading ring complex, and a micro motor is equipped with to the lower part of restriction piece to meet with the interval adjustment mechanism who establishes in the casing. The micro motor is a vibration motor or a rotating motor. The material enters from the feeding port, falls freely by the gravity of the material, passes through the gap between the blanking ring and the flow limiting block and flows out from the discharging port. The flow rate of the material passing through the gap is controlled by adjusting the change of the gap between the blanking circular ring and the flow limiting block, thereby realizing the aim of flow control. The material flow balancing device can meet the requirements of materials with different properties, can effectively overcome the arching and bridging of the materials by means of the rotation or the vibration of the flow limiting block, and keeps the flow balance of the materials.
Description
Technical field
The utility model relates to the mass flow control in a kind of fine chemistry industry production run, particularly a kind of granular material volume control device.
Background technology
The flow of control granular material, various informative in every profession and trade.Mainly contain: feeder trough, feeder, butterfly valve, slide valve etc.Its objective is the flow of effectively controlling material by these mechanisms, and keep flow even, stable.Owing to be subjected to the influence of material properties and environment for use, there are material knot arch, bridging, latch up phenomenon in process of production, cause the mass flow instability, influence product quality.In fine chemistry industry was produced, stablizing of control mass flow was even more important, and the secondary pollution problem of avoiding the material contact to cause also is to need the key problem in technology that solves in producing.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the granular material volume control device of the stable control of a kind of energy granular material flow.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of granular material volume control device, be characterized in: be provided with a vertical housing that is provided with, the top of housing is feeding mouth, lower part of frame is a discharging opening, the enclosure interior that is positioned at the feeding mouth place is fixed a blanking annulus, the below of blanking annulus is provided with the spherical or conical current limliting piece that cooperates with the blanking annulus, a micromachine is equipped with in the bottom of current limliting piece, and joins with the distance regulating mechanism that is located in the housing.
The technical problems to be solved in the utility model can also come to realize that further described micromachine is vibrating motor or electric rotating machine by the following technical programs.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, described distance regulating mechanism comprises the rotating shaft that is horizontally installed in the housing, adjustment cam is equipped with at the middle part of rotating shaft, top over against adjustment cam is provided with the adjusting slide bar, regulating one of slide bar suit supports in the sliding sleeve, support sliding sleeve and fixedly connected with housing by the cross-brace muscle, the lower end of described adjusting slide bar cooperates with adjustment cam, fixedlys connected with the shell of micromachine in the upper end of regulating slide bar.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the above-mentioned rotating shaft control hand wheel outer with being located at housing is connected.
Material enters from feeding mouth, relies on the gravity free-falling of material self, through the gap between blanking annulus and the current limliting piece, is flowed out by discharging opening.Change by the gap of regulating between blanking annulus and the current limliting piece, the mass flow by the gap just is under control, thereby has realized the purpose of flow control.The utility model compared with prior art applicable to material requirement of different nature, relies on the rotation of current limliting piece or knot arch, the bridging that vibrations can effectively overcome material, keeps the flow equalization of material.
