Abstract

The utility model discloses a particle material screening machine. The particle material screening machine comprises a rack. A main shaft is mounted on the rack and connected with a screen drum through rotary sleeves and supporting arms in a rotating mode, wherein the two ends of the screen drum are open, and the screen drum is driven by a motor. The front opening of the screen drum is a feed port. The rear opening of the screen drum is a discharge port. The main shaft and the screen drum are obliquely arranged downwards from front to back. The wall of the screen drum is provided with screen holes. The screen drum is divided into a fine screen section, a moderate screen section and a coarse screen section from front to back. The screen holes in the fine screen section are smaller than the screen holes in the moderate screen section. The screen holes in the coarse screen section are larger than the screen holes in the moderate screen section. The bottom of a material box is provided with three material outlets arranged corresponding to the fine screen section, the moderate screen section and the coarse screen section respectively. Sweeping arms extending towards the inner wall of the screen drum are mounted on the main shaft. Each sweeping arm is provided with a sweeping head which can be used for sweeping the screen holes. The particle material screening machine has the advantages of being high in screening efficiency and good in screening effect.

Description

Particulate material screening machine

Technical field

The utility model belongs to chemical fertilizer manufacturing equipment, is specifically related to a kind of particulate material screening machine.

Background technology

Existing composite chemical fertilizer is formulated by various materials.Its manufacturing process is after the many kinds of substance of nitrogenous, phosphorus, potassium is uniformly mixed, and carries out granulation, then dry or dry through comminutor, finally filters out the compound fertilizer granules of the suitable size of particle by screening machine.In the screening process of granule materials, existing screening machine is oscillatory type screening machine, it comprises frame, the top of frame from top to bottom and horizontally disposed two sieve plates, two sieve plates are driven by vibrating motor respectively, sieve aperture is set on sieve plate, sieve aperture on the sieve plate of top is greater than the sieve aperture of bottom sieve plate, while using this screening machine to screen, first material screen larger particle is selected, bottom sieve plate filters out applicable big or small granule materials, the small particles material sifting out through bottom sieve plate and the large granular materials sifting out through top sieve plate are transported to comminutor granulation again again.The shortcoming of this screening mode is, in the time throwing in more granule materials to this screening machine top, screening speed is slow, production efficiency is low, and screening effect is undesirable, easily applicable big or small granule materials is taken away with large granular materials, repeat granulation, increased production cost.

Summary of the invention

The technical problems to be solved in the utility model is for above-mentioned defect, and the particulate material screening machine that a kind of production efficiency is high, screening effect is good is provided.

In order to solve the problems of the technologies described above, the utility model provides a kind of particulate material screening machine with following structure, comprise frame, its design feature is: body feed tank is housed in frame and is connected to the main shaft on body feed tank, main shaft is rotatably connected to the screen drum by electric motor driven and open at both ends by pivoted housing and support arm, the front end of screen drum is uncovered is charging aperture, rear end opening is discharging opening, main shaft and screen drum are from going to rear-inclined to arrange downwards, the barrel of screen drum is provided with sieve aperture, screen drum is divided into dusting cover section after going to, middle sieve section and scalping section, sieve aperture in dusting cover section is less than the sieve aperture of middle sieve section, the sieve aperture of scalping section is greater than the sieve aperture of middle sieve section, body feed tank bottom is provided with respectively and dusting cover section, middle sieve section, corresponding three material outlets that arrange of scalping section, the cleaning arm that stretches to inboard wall of riddle drum is housed on main shaft, the cleaning head that can clean sieve aperture is housed on cleaning arm.

The front end of described frame is equipped with the stock guide tiltedly stretching in dusting cover section.

The rear end of body feed tank is provided with the discharge port of setting corresponding to described discharging opening.

Adopt after said structure, granule materials enters the front end of screen drum from charging aperture, successively through dusting cover section, middle sieve section and scalping section, respectively particle less and larger granularity is discharged through material outlet, enter again comminutor granulation again, middle sieve section is sifted out the granule materials warehouse-in of suitable size, driving screen drum to rotate by Motor Drive sieves, the cleaning arm arranging on main shaft and cleaning head can be cleared up sieve aperture in time, prevent from stopping up, screen drum is obliquely installed, particle just sieves and down sliding in screen drum, thereby screening speed is fast, production efficiency is high, and screening effect is good.In sum, the utlity model has the advantage that screening efficiency is high, screening effect is good.

Brief description of the drawings

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
