Problems solved by technology

The device absorbs the powder in different grooves through the movement of the suction pipe to achieve the purpose of adjusting the dust generation. In the actual operation process, it is easy to cause suction errors, the dust generation accuracy is not high, and the operation is more complicated.
The feeding of the disc groove is manual, and the dust generation capacity is not large enough to meet the needs of dust research

Embodiment Construction

[0027] like figure 1 , figure 2 , The device is composed of ash storage hopper 1, feeding disc 5, motor 7, reducer 6 and powder suction and spraying. The motor 7 is controlled by the control box 12 with a frequency converter, so it is only necessary to open a circular groove 16 with a constant trapezoidal section on the feeding disk 5, the groove 16 is concentric with the disk 5, and the groove 16 is set scraper 15.

[0028] The ash storage hopper 1 is placed on the support frame 8 to load the powder material. Due to the large discharge opening, the problem of powder material blocking is alleviated.

[0029] In order to further solve the bridging and blocking problems of powder materials, a stirring conveyor 3 is installed in the ash storage hopper 1, such as Image 6 , Figure 7 As shown, the central part of the stirring conveyor 3 is a rotating shaft 18, the top of the rotating shaft 18 is provided with a stirring rod 19, the lower end of the rotating shaft 19 is a roun...

Abstract

The constant-volume dry dust distributing apparatus consists of dust storing bin, material supplying disc, driving motor, powder sucking sprayer and other parts. It has motor driving the controlling box with frequency converter via cable, the material supplying disc with one circular groove in trapezoidal cross section, the dust storing bin with an inner stirring conveyer, the controller connected to the dust storing bin and the material supplying disc and with some small hole, the material guide unit set at the small hole and on the groove of the material supplying disc and crushing filler set also on the groove of the material supplying disc. The rotating shafts of the motor, the material supplying disc and the stirring conveyer are connected directly; and the powder sucking sprayer consists of material sucking nozzle, blowing pipe and sucking and blowing fan. The apparatus has features great dust distributing capacity, wide regulation range, etc.

Description

Technical field [0001] The invention belongs to the technical field of powder generation, and in particular relates to a device for dispersing dust generation by volume quantitative dry method. Background technique [0002] Dust generating device refers to a device that disperses solid powder into gas or air according to predetermined requirements to form a dispersed system. It is one of the indispensable means for studying dust problems. The method of redispersing powdered substances with air or other gases is called dry dispersion. [0003] Foreign dry dispersing equipment mainly includes: Wright dust generating device of Adams Company in London, England. The linear scraper is driven by a rotating combined drum. The powder is dispersed into the compressed air flow under low pressure. The air must be clean and dry, and the speed change gear can be adjusted. Drum speed, powder feed rate from micrograms to milligrams per minute. No. 2 dust generating device in New York Stat...
