Description
Technical Field
The utility model belongs to the technical field of powder unloading and transport, concretely relates to venturi type powder unloading and conveyor.
Background
In the industrial fields of chemical industry, pharmacy, food manufacturing and the like, a powder blanking and conveying device is a main device for discharging ash in a feeding, airflow conveying and dust removing device system of powder engineering. But the operating mode of difference has great difference to the unloading of powder and conveyor's requirement, the utility model discloses the unloading of a small amount of likepowder thing and granular material unloading and transport under the atmospheric pressure are applicable to the powder unloading and conveyor that correspond.
The prior art has the following problems:
1) in the existing powder blanking and conveying device, in the blanking process of a powdery material, powder is easy to bridge or accumulate at a funnel, and a blanking device cannot provide large power to enable accumulated particles to fall down, so that the particles cannot fall down automatically, and a system cannot operate normally;
2) the existing powder blanking and conveying device is used in the blanking process of a powder material, when the powder material falls into the blanking and conveying device from a storage bin vertically, the flow direction of the powder material is difficult to change by horizontal conveying airflow, and part of the powder material is always in an accumulation state, so that the system is finally blocked.
SUMMERY OF THE UTILITY MODEL
To solve the problems set forth in the background art described above. The utility model provides a venturi type powder unloading and conveyor has and prevents blockking up and prevent accumulational characteristics.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a venturi type powder unloading and conveyor, by the funnel, the unloading pipeline, the unloading control valve, gas conveying pipeline, venturi conveying section, solid conveying pipeline constitutes. The discharging control valve is arranged below the hopper and is connected with the Venturi conveying section through the discharging pipeline, and the Venturi conveying section comprises a negative pressure cavity, a contraction section, a throat pipe, a diffusion section and a solid conveying pipeline; the negative pressure cavity, the contraction section, the throat pipe and the solid conveying pipeline are connected in a welding mode; the left end of the gas conveying pipeline is horizontally inserted into the Venturi conveying section and passes through the negative pressure cavity to reach the contraction section.
Further, the funnel is connected with the venturi conveying section through the discharging pipeline.
Further, the blanking control valve is arranged on the blanking pipeline.
Further, the gas delivery line is horizontally disposed and enters the venturi delivery section from the center of the negative pressure chamber.
Further, the gas transmission pipeline horizontally extends into the contraction section.
Because the utility model discloses an above technical scheme, the technological effect of its production is obvious:
1) the utility model discloses the design in segment negative pressure chamber is carried to venturi, can effectively realize the stable unloading of low discharge powder. The control of powder unloading volume is realized to the unloading control valve, and the negative pressure that venturi conveying section gas drive produced can destroy the bridging phenomenon that the powder appears, avoids the powder to appear blockking up in funnel or unloading control valve department.
2) The utility model discloses the design of venturi type transport section can effectively realize the high-efficient mixture of gas and solid powder, makes the easy air current of being taken away by high-speed motion of powder, effectively avoids the powder to be because of the accumulational phenomenon that the transition of mobile state caused in the horizontal transport section.
Drawings
Fig. 1 is a schematic view of the overall structure of a venturi-type powder blanking and conveying device.
In the figure: the device comprises a hopper 1, a blanking pipeline 2, a blanking control valve 3, a gas conveying pipeline 4, a negative pressure cavity 5, a solid conveying pipeline 6, a diffusion section 7, a throat 8 and a contraction section 9.
Detailed Description
The present invention will be further explained by the following embodiments with reference to the drawings.
Referring to fig. 1, a venturi-type powder feeding and conveying device is composed of a hopper, a feeding pipeline, a feeding control valve, a gas conveying pipeline and a venturi conveying section. Wherein, the venturi conveying section comprises a negative pressure cavity 5, a solid conveying pipeline 6, a diffusion section 7, a throat 8 and a contraction section 9, and is connected in a welding mode according to the arrangement shown in the figure. The hopper 1 and the negative pressure cavity 5 are connected by the blanking pipeline 2 in a welding mode, and the blanking control valve 3 is arranged on the blanking pipeline 2. The gas transmission line 4 is inserted horizontally into the left end of the negative pressure chamber 5 and reaches the constricted section 9, and is connected to the negative pressure chamber 5 by welding.
In this embodiment: need other equipment to assist when carrying out unloading and carrying the operation, auxiliary device includes compressor, dust collecting equipment, holding tank and electronic scale.
The Venturi type powder blanking and conveying device is connected with the auxiliary device. 1. The gas conveying pipeline of the Venturi type powder blanking and conveying device is connected with the auxiliary compressor. 2. The right end of a solid conveying pipeline of the Venturi type powder blanking and conveying device is connected with the auxiliary collecting tank. 3. The auxiliary collecting tank is connected with the auxiliary dust removing equipment.
After the connection is finished, the implementation is started, and firstly, 30 kilograms of powdery materials are put into a material storage tank; opening the compressor, the pressure value is 200KPa, opening unloading control valve 3 again, make the material fall into negative pressure cavity 5, after a period of time, close the compressor, after making the material deposit, take out the powder in the collecting tank, weigh the powder quality with the electronic scale. Repeating the steps 3 times after the implementation, eliminating the influence of the powder mass adhered to the inner walls of the storage tank and the collecting tank, and weighing the powder masses respectively at 29.5 kg, 29.4 kg and 29.6 kg by using an electronic scale, which indicates that no powder blockage or large-amount accumulation condition occurs in the Venturi type powder blanking and conveying device.
