Description

There is the grater grinding storehouse of automatic blanking function

Technical field

The invention belongs to grater technical field, particularly a kind of grater grinding storehouse with automatic blanking function.

Background technology

In industrial and agricultural production, often need to adopt grinding machine to carry out pulverization process to various material.Grinding machine, according to the difference of milling medium and grinding material, can be divided into: ball mill, column mill, rod mill, tube mill, autogenous tumbling mill, revolve mortar formula roller mill, Vertical Mill, multilayer Vertical Mill, vertical roll grinder, DMC grinding machine etc.Generally intermittent ball mill is adopted in Ceramic production, adopt wet production, its abrasive action can be divided into two parts, one be between abrasive body and abrasive body and simplified between abrasive action, two be abrasive body fall time percussion, will start with from these two aspects to improve grinding efficiency." much broken and lessmill " technology of metallic ore and technique are one and have carried the topic of a lot of years, reduce the mill feed size of ball mill, before ball mill, increase by one section of pre-grinding or ultrafine grinding technique, are the important technology innovations that bargh saves energy and reduce the cost.The research of grinding machine rock processing is one of emphasis in Mineral Processing Engineering technology.Rock processing be utilize energy to extrude ore by grinding machine, roll extrusion, impact and grinding, make valuable mineral monomer cleavage in ore (from), be beneficial to the process that the next stage carries out sorting.

Grinding machine is applicable to pulverize the Mohs' hardness such as barite, calcite, potassic feldspar, talcum, marble, lime stone, gypsum, quartz, atlapulgite, active carbon, bentonite, kaolin, glass, manganese ore, titanium ore, chrome ore, slag and is not more than 7 grades, the nonmetallic mineral that the non-flammable of humidity below 6% is explosive.Grinding machine adopts mill revolution, the rotation of mill axle, spring to adjust cane grinding roller assembly structure, strengthen grinding roller roller skin to express material intensity and shear ability; thus reach the effect of strengthening abrasive dust; have output high, grind the fineness of materials high (powder is careful) come, old-fashioned grinding machine can the continuous powder process of dry method (stream time can not more than 24 hours), because the bearing in old-fashioned grinding roller assembly uses lubricating grease (lubricating grease must be shut down and be annotated once so can not more than 24 hours in 24 hours).But new-type is that the life cycle using lubricating oil (being commonly called as machine oil) can reach whole grinding roller owing to employing the lubricating oil the longest available machine time is shut down once, changes grinding roller and lubricating oil inspection (supplementing some lubricating oil again when needing).

Traditional rotary type grater comprises the cylindrical tube that the axis around basic horizontal rotates.The cylinder rotated is supplied with the such as granule materials such as slurry or powder, and cylinder rotates with 3/1 to four/2nds of " critical speed " (that is, the material at cylinder inner surface place contacts and the minimum speed of advancing around it with grater) simultaneously.The material of traditional grater cannot realize automatic feed and discharging mostly, easily cause material to pile up in feed pipe, and after stopping feed, the material in feed bin all cannot enter in cylinder and grind, need manually to clear up, the low and waste of manpower resource of production efficiency.

Summary of the invention

The object of the invention is to be achieved through the following technical solutions: the grater grinding storehouse with automatic blanking function, comprise grinding warehouse, be positioned at the decompression chamber above grinding warehouse, be positioned at the discharge pipe at decompression chamber top, and be looped around the blast pipe outside grinding warehouse; Discharge pipe inside is provided with pulse dust collector, and blast pipe is provided with multiple air admission hole with the side of grinding warehouse joint;

Described grinding warehouse comprises the feed pipe, feed bin, discharge nozzle and the U-shaped annular groove that are arranged on inside, the charging aperture of feed pipe stretches out the side of grinding warehouse, the discharging opening of feed pipe is connected with the feeding mouth of feed bin, feed bin fixed installation on the rotary shaft, the side of feed bin is provided with at least one feed bin discharge hole, feed bin discharge hole is fixedly connected with discharge nozzle, and the discharging opening of discharge nozzle connects U-shaped annular groove;

Described feed bin is the column construction that top and bottom are regular polygon, each side of feed bin is rectangle, described feed bin discharge hole lays respectively in each rectangle sides of feed bin, feed bin discharge hole is arranged near feed bin bottom surface place on feed bin side, and the under shed of feed bin discharge hole and feed bin bottom surface are with high.

The invention has the beneficial effects as follows:

1, multiple feed bin discharge hole is set in feed bin side, material can be sprinkled upon the multiple places in U-loop groove by discharge nozzle, material is disperseed rapidly in U-loop groove, be laid in U-shaped annular groove, material is more evenly distributed, and improve the operating efficiency of grater, and material can glide voluntarily, without the need to artificial feeding, easy to use;

2, feed bin discharge hole is arranged near feed bin bottom surface place in feed bin rectangle sides, and the under shed of feed bin discharge hole and feed bin bottom surface, with high, can make the material in feed bin all enter U-shaped annular groove, easy to use;
