Abstract

The invention discloses an automatic discharging system of a bowl mill unit. The system comprises several bowl mills, each of which includes a frame, a grinding cylinder and rotating shafts located at two ends of the grinding cylinder. At least one rotating shaft of one end is provided with a discharging hole inside, and the inner end of the discharging hole is communicated with the inner space of the grinding cylinder, while the outer end of the discharging hole is connected to a discharging branch pipe through a synchronizer. The discharging branch pipes of each bowl mill are communicated by a discharging main pipe in order, and one end of the discharging main pipe is provided with a draught fan. The system of the invention not only has simple structure, convenient operation, and the functions of mitigating dust dispersion during processing, improving the operational environment as well as reducing raw material loss, but also can realize the unified discharging of multiple bowl mills in the bowl mill unit, thus improving the operation efficiency substantially.

Description

The automatic discharge system of ball milling unit

Technical field

The invention belongs to the material fine crushing equipment, relate in particular to the automatic discharge system of ball milling unit.

Background technology

Carbon molecular sieve is as a kind of new adsorbent product, it mainly acts on is separation of air enrichment nitrogen (or oxygen), is widely used in aspects such as chemical industry, industrial gas oil, electronics industry, food industry, coal industry, medical industry, cable industry, metal heat treatmet, transportation and storage.The carbon molecular sieve raw material also needs the broken requirement that could satisfy following process of fine powder through ball mill after will passing through the coarse crushing of disintegrating machine.Ball mill is after material is broken, the key equipment of pulverizing again, be widely used in cement, silicate product, New Building Materials, refractory material, chemical fertilizer, black and production industries such as non-ferrous metal ore and glass ceramics carry out dry type or wet type grinding to various ores and other grindability material.

The structure of existing ball mill as shown in Figure 1, have frame 01, abrasive roller 02, have dumping pit 03 on abrasive roller 02 barrel, there is following shortcoming in above-mentioned ball mill in actual production: in discharge process, tiny powdered material also is in flow regime, under the drive of grinding cylinder, go out to dumping pit, and tube (bag) 04 that connect material that is placed on below the dumping pit can not receive all powders fully, some powder disperse is to the workshop, not only cause the raw material loss, also can cause harmful effect surrounding enviroment and operator's health; In addition, general enterprises all is equipped with many table grinders, if all dischargings in the above described manner of every table grinder, with the operating efficiency of influence integral body greatly, production cost can not get effective control.

Summary of the invention

Problem to be solved by this invention just provides simple in structure, the easy to operate automatic discharge system of ball milling unit, can not only alleviate the situation of dust disperse in the process, improves operating environment, reduces the raw material loss; Can also realize the unified discharging of many table grinders, operating efficiency significantly improves.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: the automatic discharge system of ball milling unit, comprise some table grinders, described ball mill comprises frame, sand cylinder and the rotating shaft of being located at the sand cylinder two ends, it is characterized in that: be provided with discharge opening in the rotating shaft of at least one end on the sand cylinder, the inner sand cylinder inner space that is communicated with of discharge opening, the discharge opening outer end is connected with the discharging arm by synchronized, the discharging arm of each table grinder is responsible for successively by a discharging and is communicated with, and discharging is responsible for an end and is provided with air-introduced machine.

Further, also be provided with the manhole that passes through for personnel on the described sand cylinder barrel.Manhole can also use as charging aperture except passing in and out for the maintenance personal.

Further, the inner of described discharge opening also is provided with grate plate, has the comb hole of some apertures less than mill ball diameter in the sand cylinder on grate plate.

Further, described discharging also is provided with sack cleaner on being responsible for.

Beneficial effect of the present invention: as can be known by technique scheme, the present invention changes the independent discharging of traditional many table grinders, shuts down the working method of discharging: material is finished refinement in ball mill after, enter the discharge opening in the rotating shaft, effect by air-introduced machine enters the discharging arm again, by the discharging person in charge powder in each discharging arm is unified to collect, introduce sack cleaner by air-introduced machine again and filter dirt, need not manually-operated during this, reduced the infringement of dust human body; Operating efficiency significantly improves; Also alleviated the situation of dust disperse in the process simultaneously, improved operating environment, the raw material loss is little, has effectively controlled production cost.

Description of drawings

The present invention is described further below in conjunction with accompanying drawing:

Fig. 1 is the discharging schematic diagram of existing ball mill;

Fig. 2 is the discharging schematic diagram of ball mill of the present invention;

Fig. 3 is the discharging schematic diagram of ball milling unit of the present invention.

The specific embodiment

With reference to Fig. 2,3, the automatic discharge system of ball milling unit of the present invention, comprise three table grinders, the rotating shaft 22 that ball mill has frame 1, sand cylinder 2 and is located at sand cylinder 2 two ends, be provided with discharge opening 221 in the rotating shaft 22 of right-hand member on the sand cylinder 2, discharge opening 221 inner sand cylinder 2 inner spaces that are communicated with, discharge opening 221 outer ends are connected with discharging arm 4 by synchronized 3, the discharging arm 4 of three table grinders is responsible for 6 by a discharging and is communicated with successively, and discharging is responsible for 6 one ends and is provided with air-introduced machine 7, sack cleaner 8; Also be provided with the manhole 21 that passes through for personnel on sand cylinder 2 barrels; Discharge opening 221 the inners also are provided with grate plate 222, have the comb hole of some apertures less than mill ball diameter in the sand cylinder 2 on grate plate 222.

The course of work: raw material enters in the sand cylinder 2 from manhole, motor rotates by the synchronizing wheel 5 that belt pulley drives in the sand cylinder 2 left end rotating shafts 22, in the ball mill course of work, constantly entered discharging arm 4 by the powder of refinement from discharge opening 221, under the effect of air-introduced machine 7, the powder that discharging is responsible in 6 pairs of each discharging arms 4 is unified to collect, and enters sack cleaner 8 filter dirt again; Need not manually-operated during this time; Reduced the infringement of dust to human body; Operating efficiency significantly improves; Also alleviated the situation of dust disperse in the process simultaneously, improved operating environment, the raw material loss is little, has effectively controlled production cost.
