Abstract

The utility model relates to a crushing disposal device, in particular to a vertical rotar cutter plastic disintegrator. The utility model comprises a mainshaft, a movable cutter, a fixed cutter, and a crushing bin. The utility model is characterized in that a rotatable mainshaft is vertically arranged in the crushing bin; the upper part of the mainshaft is fixed with a material pulling device; the mainshaft on the lower part of the material pulling device is fixed with one or more movable cutters; the internal wall of the crushing bin is fixed with a fixed cutter matched with the movable cutter; the bin wall at the lower part of the material bin is provided with a hole; the exterior of the bin wall with the hole is fixed with a material receiving bin. As the utility model changes the original horizontal crushing into vertical crushing and correspondingly improves the structure of the device, the tool has the advantages of being difficult to block the cutter, high crushing efficiency, small noise, being easy to adjust the crushing grain diameter, and being extremely suitable for the plastic processing enterprises with large crushing quantity.

Description

Vertical rotating cutter plastic crusher

Technical field

The utility model relates to pulverization process equipment, particularly vertical rotating cutter plastic crusher.

Background technology

Present normally used plastic crusher, what mainly adopt is horizontal pulverizing, it is the main shaft horizontal positioned, moving knife is installed on the main shaft, stationary knife is fixed between screen cloth and the feed bin, when moving knife rotates at a high speed, by the shear action between moving knife and the stationary knife, plastics are pulverized, and the particle that reaches certain particle size after the pulverizing falls by screen cloth.Can't continue by the particle of screen cloth in pulverizing chamber, to pulverize.The major defect of horizontal pulverizer has: 1. easy swaging clamp in the crushing process.Because being level, the moving knife of this machine, stationary knife install, when pulverizing, the material that will need to pulverize by moving knife sweeps, when material excessive when material or that sweep is too much, because material does not have activity space between moving knife and stationary knife, moving knife is stuck, as handles untimely, will produce motor and be burnt, whole the phenomenon that equipment can't use; 2. efficient is lower.In order to prevent the generation of stuck phenomenon, to limit for each inlet amount, can not continuous feed, the granular size to charging also will have corresponding requirement simultaneously, and so, the efficient of crushing process will reduce; 3. noise is bigger, because action of centrifugal force, material directly impinges upon feed bin sidewall and top, produces very big noise.

Summary of the invention

Because the utility model changes original horizontal pulverizing into vertical pulverizing, simultaneously structure has been carried out corresponding improvement, thereby these facility has following characteristics: 1. be difficult for swaging clamp.When too big or too many, because moving knife has an angle with stationary knife, material can move up automatically, is extruded the shear zone as material, and analysis can not produce the swaging clamp phenomenon theoretically; 2. crush efficiency height.Because solved the problem of swaging clamp from structure, but continuous feed, and to the essentially no restriction of material size, thereby can continuous charging and discharging continuously, improved crush efficiency effectively; 3. because material is along bin wall rotation all the time, thus little to the impact of bin wall, and noise is also little.4. the powder particle diameter adjustment is easy, according to the requirement of powder particle diameter, installs the variation that corresponding hole pattern just can be realized particle diameter additional on the bulkhead with holes of pulverizing storehouse.

The technical solution of the utility model is: a kind of vertical rotating cutter plastic crusher, comprise main shaft, moving knife, stationary knife, pulverizing storehouse, it is characterized in that in pulverizing the storehouse, being vertically installed with a rotatable shaft, be fixed with on main shaft top and pull out glassware, on the main shaft that pulls out the glassware bottom, be fixed with one or one above moving knife, be fixed with the stationary knife that matches with moving knife at the inwall of pulverizing the storehouse; Have the hole on the bulkhead of feed bin bottom, outside the bulkhead of perforate, be fixed with the storehouse that connects material.

Stationary knife and horizontal plane have an angle, and like this when pulverizing plastics, the shear surface between moving, the stationary knife reduces, and has both put contact, can prevent the generation of swaging clamp phenomenon effectively.

Be fixed with striker plate on the top bulkhead in pulverizing storehouse, striker plate can prevent material in crushing process, outside the feed bin that flies out.

Be fixed with arc deflector between the inwall in stationary knife and pulverizing storehouse, the effect of arc deflector mainly is when moving knife is scraped material, prevents the accumulation of material, makes material enter the shear zone in an orderly manner.

Accompanying drawing 2 is the vertical view of the utility model structural representation.

The specific embodiment

As shown in Figure 1, 2, this pulverizer is vertically installed with a rotatable shaft in pulverizing storehouse 1, be fixed with on main shaft top and pull out glassware 3, is fixed with three moving knife 5 on the main shaft that pulls out the glassware bottom, is fixed with the stationary knife 6 that matches with moving knife at the inwall of pulverizing the storehouse; Have hole 4 on the bulkhead of feed bin bottom, form screen cloth, be fixed with the storehouse 8 that connects material outside the bulkhead of perforate, a side lower part in the storehouse that connects material has a discharging opening; One angle is arranged between stationary knife and the main shaft, and like this when pulverizing plastics, the shear surface between moving, the stationary knife reduces, and has both put contact, can prevent the generation of swaging clamp phenomenon effectively.Be fixed with striker plate 2 on the top bulkhead in pulverizing storehouse, striker plate can prevent material in crushing process, outside the feed bin that flies out.Be fixed with arc deflector 9 between the inwall in stationary knife and pulverizing storehouse, the effect of arc deflector mainly is when moving knife is scraped material, prevents the accumulation of material, makes material enter the shear zone in an orderly manner.The flywheel 7 that main shaft is installed by the lower end makes main axis rotation.When needs are adjusted powder particle diameter,, on the bulkhead with holes of pulverizing storehouse, install the variation that corresponding hole pattern just can be realized particle diameter additional according to the requirement of powder particle diameter.Material after the pulverizing falls into the storehouse that connects material through screen cloth, and a discharging opening of the side lower part by the storehouse that connects material flows out.
