Description

A kind of horizontal comminutor with wear extent compensation function

Technical field

It the utility model is related to the technical field of energy supply for metallurgy environmental protection, more particularly to a kind of horizontal comminutor.

Background technology

In the production process of fertilizer, include the production process of complex fertilizer, organic fertilizer and organic-inorganic complex fertilizer In, often need to carry out the processing of moisture content and fineness to being granulated material, especially pure fertilizer granulation is even more strict；Fertilizer at present Granulation process can be divided into slurry process, granulating method and extrinsion pressing by technique, and the particle situation of complex fertilizer is to weigh fertilizer product One of important indicator of matter.The particularly granulation of organic fertilizer, mainly using disc granulation, due to its initial material species, The factors such as character and granularity so that extensive be granulated of industrialization has many difficulties, is embodied in following weak point ：First, workload is big, working environment is poor；Second, balling ratio is low, production efficiency is difficult to improve, third, poor appearance after balling-up, moisture content It is high.At present only using specification of equipment is increased, using larger product, repeatedly granulation is low to make up balling ratio repeatedly, improves production Amount, extend technological process, increase equipment investment to meet fineness of materials and moisture content requirement.

Patent No. 201420315324.X discloses a kind of horizontal centrifugal organic fertilizer granulator, solves the production of fertilizer The above mentioned problem that journey runs into.But there is following defect for the device simultaneously：Relative position between cylinder and central rotating shaft is solid Fixed, it can not adjust.At the initial stage used, cutter head and cylinder gap value are smaller, do not influence this centrifugal granulation.But with knife For head by the continuous wear down of cylinder, both gap values are increasing, do not adjust gap between the two, and granulation can be caused not complete. Therefore said structure centrifugal comminutor, in the prevalence of the life-span it is too short the problem of.

The content of the invention

The technical problems to be solved by the invention are：For said structure defect existing for horizontal comminutor, one is proposed Kind can adjust the horizontal comminutor of blade and cylinder gap value, ensure centrifugal granulation outcome, extend making for comminutor to realize With the purpose in life-span.

To reach above-mentioned purpose, embodiment of the present utility model adopts the following technical scheme that：

A kind of horizontal comminutor with wear extent compensation function, including cylinder, main shaft, knife bar, cutter head and motor, Left bearing assembly, right bearing assembly；The both ends of the cylinder are in closed, and charging is offered on the upside of the left end of the cylinder Mouthful, offer discharging opening on the downside of its right-hand member；Two axle journals of described main shaft, respectively by left bearing assembly, right bearing assembly branch Hold, the stage casing of main shaft is sleeved in cylinder；Described cutter head is packed in the upper end of knife bar, knife bar row pattern in spiral distribution It is packed in by its lower end on main shaft；The motor is connected by V belt translation with main shaft；Described left bearing assembly, right branch Bearing assembly structure is identical, is formed by bearing block, bearing, jump ring, support column, fulcrum bearing；Described bearing is arranged on bearing block In, its outer ring is fixed by jump ring, and it is connected, separately close to the inner ring end face of cylinder side by the shaft shoulder of sleeve and main shaft The inner ring end face of side, it is connected by axially position nut with main shaft；The outer ring of described bearing block is connected with support column；It is described The lower end of support column be provided with adjusting nut, and by adjusting nut, be sleeved in fulcrum bearing.

Further, it is described to be fixed on row pattern knife bar in spiral distribution on main shaft and be made up of two to five rows.

Further, it is respectively fixed with strengthened connection bar on each row pattern knife bar in spiral distribution.

Further, conveying watt is fixed with the shape of a spiral on the main shaft positioned at charging aperture.

Further, the barrel diameter at the charging aperture is less than 0.3-0.4 meter of the barrel diameter of discharge outlet.

Further, sealing ring is additionally provided between described main shaft and cylinder junction, for sealing between the two.

Further, in institute's rheme support column lower end, also overturn-preventing nut, described overturn-preventing nut is with adjusting spiral shell Parent phase pair, the inside and outside both sides of fulcrum bearing upper surface are separately positioned on, play a part of preventing support column from toppling.

The beneficial effect that the utility model can be reached using above-mentioned technical solution is：

1st, this grain-making machine use built in multi-detector knife bar form, high speed rotation centrifugal action under rubbing into Shape, not only balling ratio is high, and in granulation process, while with 40 degrees Celsius of temperature rise, have to drying for fertiliser granulates There is positive role；2nd, it is less demanding to the raw material granularity of organic fertilizer, it is easy to produce；3rd, a balling ratio height, apparatus for production line Obtain simplifying significantly, reduced the input of complete set of equipments, shortened the technological process of organic fertilizer production, improved production effect Rate, reduce artificial and energy consumption；4th, material granulating and forming completely in cylinder, the environmental sanitation of production has been effectively ensured；5th, enter Barrel diameter at material mouth is less than the barrel diameter of discharge outlet, makes material positive feed more smooth fully, prevents material from making Returned during grain and tell the anomalies such as material or sizing；6th, when cutter head and barrel wear for a period of time after, adjust left and right bearing assembly Helix length, the height of main shaft is adjusted so that cutter head is close to again with cylinder, and the longevity is used so as to reach extension fixture The purpose of life, there is simple, convenient quick feature, while transmission device employs tape handler, adjustment main shaft will not Influence its transmission accuracy and efficiency；7th, after cylinder is galled by cutter head, only need to change cylinder, it is not necessary to changing main-spindle and its His part, and the action of cylinder is changed, it is easier to operate, i.e., only needs to dismantle correspondingly axially position nut, you can realization. So as to further increase the economy of horizontal comminutor, O＆M cost is reduced, meets the principle of recycling.

A kind of horizontal comminutor with wear extent compensation function that the utility model embodiment provides, by setting main shaft Height adjustable device, the compensation of cutter head and barrel wear gap value is realized, so as to extend making for existing horizontal comminutor With the life-span, there is preferably practical value, be easy to existing horizontal comminutor further genralrlization to use.
