Embodiment 1
[0029] Taking the laboratory dust removal equipment experiment as an example, when the dust removal equipment is tested for efficiency, such as figure 2 shown, including the following steps:
[0030] Step 1) Install the vertical micro-feeding device on the air inlet pipe 7-1 of the dust removal equipment 7, and put the powdery material into the funnel 3;
[0031] Step 2) Start the stepping motor switch button to drive the screw 2 to rotate, and the material is taken out of the funnel 3 under the driving action of the screw 2;
[0032] Step 3) The material falls and enters the air inlet pipe 7-1. Under the action of the material dispersing device 5, the material gathered together due to the pressure between the screw 2 and the screw sleeve 4 is dispersed, so that it can be fed evenly and dispersedly. ;
[0033] Step 4) Use the frequency conversion speed control device of the stepping motor to adjust the motor speed and change the rotation speed of the screw 2 to control the ...

Abstract
The invention relates to a vertical micro feeding device and method. The vertical micro feeding device comprises a speed changing device, a bracket, a material dispersing device, a screw sleeve, a funnel and a screw, the funnel is arranged under the speed changing device, and the speed changing device and the funnel are both fixedly installed at a gas flow inlet of dust removing equipment throughthe bracket; an output shaft of the speed changing device is connected with the screw, the bottom end of the screw penetrates through a discharging port of the funnel to enter a gas flow inlet pipeline, and the material dispersing device is connected to the bottom end of the screw; and the screw sleeve is embedded into the discharging port of the funnel and located on the exterior of the screw, and the appropriate space allowance is reserved between the screw and the screw sleeve. The speed changing device adjusts the rotation speed of a stepping motor to drive the screw to supply the stable driving force; the screw, the screw sleeve and the material dispersing device are cooperatively used, and materials can be dispersedly, uniformly and continuously fed; the funnel ensures surplus material feeding, and then material feeding can not be disconnected; and the bracket ensures that the screw, the screw sleeve and an outlet of the funnel are aligned and located on the same straight line, and finally dispersed, uniform, stable and continuous feeding is achieved.
Description
technical field [0001] The invention relates to a device and method for dispersing, uniform, trace and continuous feeding in an industrial or laboratory application process, in particular to a vertical trace feeding device and method. Background technique [0002] Dust feeding device is relatively common in dust removal efficiency tests of various dust removal equipment. Its characteristic is that it needs to strictly control the amount of dust feeding, and it can disperse, evenly and continuously carry out micro-dosing of materials. Now there are usually three types of micro-feeding equipment: screw type, wheel-type and roller-type. For the feeding amount of tens of grams or hundreds of grams per hour, the dust produced by these devices is easy to stick, and the feeding is not continuous. The dust is easy to stick to the pipe wall and the feeding speed is low, which causes the dust at the discharge port to form larger particles, discontinuous and uneven blanking, and unstab...
