Abstract
The utility model discloses a material flow velocity controller used on screening equipment. The controller comprises a rotary valve, a driving mechanism, a metering mechanism and a control unit, the rotary valve which can rotate is mounted at the feed inlet of the screening equipment, the driving mechanism is used for driving the rotary valve to rotate, the metering mechanism is used for detecting the instant discharge rate of the screening equipment on line, the control unit controls the rotation speed of the rotary valve according to the discharge rate detected by the metering mechanism, and the rotary valve comprises a plurality of rotary blades. The controller can effectively control the discharge speed, the control precision is high, the screening efficiency is increased, and the stability of the operation of the screening equipment is guaranteed.
Description
Technical field
The utility model relates to the material flow control device that a kind of screening plant is used, and it is in control chemical material screening flow velocity.
Background technology
The butterfly valve that present screening plant and similar device are installed by the top is controlled the flow velocity of material, flow is difficult to the certain speed of control, and is many sometimes few sometimes, influences screening effect, can surpass the capacity value of screening and similar devices when flow is excessive, cause the damage of equipment.Otherwise, can influence the operating efficiency and the effect of screening when flow is too small.
Summary of the invention
Technical problem to be solved in the utility model is to overcome deficiency of the prior art, and the material flow of using on a kind of screening plant and similar device control device is provided, and this device control accuracy height can be according to the actual blanking ability control blanking amount of screening plant.
For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of material flow control device that is used on the screening plant, it comprise the charging aperture place that is installed in screening plant the rotary valve that can rotate, be used to drive the driving mechanism that rotary valve rotates, the metering device that is used for the instant blanking amount of online detection screening plant, control the control device of the velocity of rotation of described rotary valve according to the detected blanking amount of metering device, rotary valve comprises rotating shaft and is fixed on a plurality of rotating vanes in the rotating shaft.
According to further embodiment of the present utility model: a plurality of described rotating vanes circumferentially evenly distribute around the rotating shaft of rotary valve.Described driving mechanism comprises variable-frequency motor, by the tooth belt that variable-frequency motor drives, the rotating shaft of described rotary valve is driven by tooth belt and rotates.
Owing to take technique scheme, the utility model compared with prior art has following advantage:
The utility model adopts the rotary valve that includes a plurality of rotating vanes to be connected with screening plant, and the mass flow with rotary valve of this structure changes with its rotary speed.So, the actual blanking amount of the screening plant that records according to metering device can be controlled rotary valve and be in corresponding rotating speed under this blanking amount, guarantees that the blanking amount is consistent with the blanking amount of the actual requirement of screening plant.The utility model can effectively be controlled blanking velocity, control accuracy height, the stability that has improved screening efficiency and guaranteed screening plant work.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the present invention is done and to describe in further detail:
As shown in Figures 1 to 3, comprise the rotary valve 5 that charging aperture 2 places that are installed in screening plant can rotate, be used to drive the driving mechanism that described rotary valve 5 rotates, the metering device (not shown) that is used for the instant blanking amount of online detection screening plant, control the control device of the velocity of rotation of rotary valve 5 according to the detected blanking amount of metering device according to the material flow control device of present embodiment, described rotary valve 5 comprises rotating shaft 50 and is fixed on a plurality of rotating vanes 51 in the rotating shaft 50.A plurality of rotating vanes 51 are around the circumferentially evenly distribution of the rotating shaft 50 of rotary valve 5.The tooth belt 4 that described driving mechanism comprises variable-frequency motor 1, driven by variable-frequency motor 1 and be located at the outer tooth belt cover 3 of tooth belt 4.The rotating shaft 50 of described rotary valve 5 is driven by described tooth belt 4 and rotates.The driving mechanism that is used to drive rotary valve 5 mainly is made of variable-frequency motor 1 and tooth belt 4, pass through the transmission of tooth belt 4 by variable-frequency motor 1 different operating frequency, make rotary valve 5 that different rotating speeds be arranged, calculate actual blanking amount by the metering device of online detection screening plant blanking amount, meanwhile the control device velocity of rotation of controlling rotary valve 5 according to detected blanking amount makes mass flow consistent with the blanking amount of actual requirement.
The utility model can effectively be controlled blanking velocity, in the hope of reaching the purpose of even blanking, and the stability that has improved screening efficiency and guaranteed screening plant work.
More than the utility model has been done detailed description, its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented, and can not limit protection domain of the present utility model with this.All equivalences of doing according to spiritual essence of the present utility model change or modify, and all should be encompassed within the protection domain of the present utility model.
