Abstract
The utility model relates to a blade pulverizer, which mainly comprises a feeding port, a shell, a blade assembly, a belt wheel, a transmission shaft and a screening piece, wherein the blade assembly consists of blades, a spacer, a penetrating strip and a connecting disc; the blades are arranged on the connecting disc; two fixed holes are formed on each blade; the penetrating strip penetrates through the fixed holes to fix the blades; and every two blades are partitioned by the spacer; 3-5 separation chambers are arranged on the pulverizer, are positioned at the upper part of the blade assembly and are partitioned by a partition board. The blades are made of Q235 steels or stainless steels; edge parts of the blades are coated with wear-resistant coating layers; and coatings of the wear-resistant coating layers are cobalt-base alloy X-40. Through structures of the separation chambers, big and small particles are effectively separated in the pulverizer, so that excessive pulverization of the small particle materials can be avoided, and the content of powder in the product is reduced. With the adoption of the blade pulverizer, the thicknesses of the blades of the wear-resistant coating layers are small, the intensity is high, the durability is good and the installation is convenient; and compared with the traditional pulverizer, the finished product ratio of the pulverized product is improved by over 20 percent.
Description
Technical field
The utility model belongs to grain, medical treatment, chemical industry and feed processing technology field, relates to a kind of blade pulverizer, is specifically related to a kind of separation cell-type blade pulverizer.
Background technology
In the modernized big insutry, many product needed are crushed into lump material and do not contain particles of powder shape material, and ordinary circumstance is to utilize screening plant that powder in the comminuting matter is removed.Pulverizer equipment exists overground problem at present, makes the formed product rate of particle low, and powder is many.Though equipment such as ACM impact grinding have been avoided overground phenomenon, because cost is high, and needs blowing system, so range of application is restricted.Particle diameter requires the particle manufacture about 1mm, mainly relies on cheap hammer or blade type pulverizer to realize.
The improvement of hammer and blade type pulverizer in recent years continues to bring out, for example: the utilization of grinding tooth plate, water droplet formula beater grinder etc.But the improvement of these disintegrating apparatus is mainly carried out on enhancing productivity, and less for the improvement of avoiding material excessively to pulverize.The a large amount of powder materials that produce in the production, or need process granulation again and pulverize again, or be wasted as waste product.Concerning production had the pulverizer of grain size product requirement, finished product rate and production efficiency were of equal importance.
Publication number be the Chinese invention patent application of CN102240580A open " a kind of hammer crusher mainly comprises charging aperture (1), hammer leaf (2), rotor (3), epitrochanterian rotating disk (4), blade (5), motor (6), pulverizer discharging opening (7), body (8), sieve sheet (9), door (10), presses screen frame (11), wherein; be added with air blade (5) between rotating disk and the rotating disk, has 2 to become the one linear installation of 180 degree between every grade, and two grades adjacent fan blade is in the right angle; rotating disk (4) is going out out several air vents near rotating shaft, like this, when rotor rotate; wind can be from the pulverizer both sides gap location air intake of axis hole, pass the air vent of rotating disk again, under the agitating of fan blade; the partial material that will remain in the lost motion of rotor center is shifted hammer leaf end place rapidly onto and pulverized by hammer leaf; simultaneously, by fan blade a kind of blast of pulsatile change is provided, the negative pressure outside having destroyed the uniform centrifugal force of material ring in the sieve and having sieved; Thereby improve the uniformity of output and material, improve stifled sieve phenomenon.”。But this patent application does not solve the yield rate problem that milling product was excessively pulverized and improved to pulverizer.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art, the utility model provides a kind of blade pulverizer, and the improvement of carrying out at blade type pulverizer or beater grinder is to improve efficiency of equipment and formed product rate.
The utility model blade pulverizer mainly comprises charging aperture, housing, blade assembly, belt pulley, power transmission shaft and sieve sheet.Blade assembly comprises blade, partition, wears bar and terminal pad.Blade is installed on the terminal pad, and blade is provided with fixing hole, wears bar and passes the fixing hole fixed blade, separates with partition between per two blades.Pulverizer is provided with 3～5 separation chambers, and the separation chamber is positioned at the top of blade assembly, separates with dividing plate between the separation chamber.
The height B of central partition plate is 30-60mm, and the distance H between the dividing plate is 45-100mm, and dividing plate is 5～15 mm to blade end apart from F.Blade is provided with two fixing holes.The material of blade is the Q235 steel or stainless steel, and the thickness of blade is 1～10mm, and the blade of blade scribbles the wear-resistant paint layer, and the coating of wear-resistant paint layer is cobalt-base alloys X-40.The sieve diameter of sieve sheet is 0.5～3 mm, and the thickness of sieve sheet is 0.5～2mm.
The utility model blade type pulverizer has increased separation chamber's structure; Make size particles in the inner effectively separation of pulverizer; Use has the pulverizer of separation chamber's structure, and large granular materials returns the blade Rotary District again and pulverized once more in crushing process, and small particles material no longer gets into the blade Rotary District and pulverizes; Avoid the excessive pulverizing of small particles material, reduce the content of powder in the product.On the installation form and structure of blade, through two fixing hole fixed blades, reducing of blade thickness conveniently installed.Simultaneously, because thickness reduces, the blade assembling is more compact, and the blade assembly group is installed more firm.Through at blade spraying abrasion-proof dope layer, improved the intensity and the durability of blade.The utility model separates the cell-type pulverizer to be compared with conventional knives chip pulverizer, beater disintegrating machine and water droplet formula pulverizer, and the yield rate of milling product improves more than 20%, and through improving the mounting means of blade, yield rate can further improve.
