Description
Technical field
The utility model relates to milling equipment technical field, especially relates to a kind of discharge grid plate for screen analysis material.
Background technology
Discharge grid plate is the critical component of milling equipment, mainly contains three and acts on greatly: 1, got rid of by the material of grinding machine inside in time, controls material ball ratio and the residence time of material of grinding machine afterbody; 2, improve the ventilation condition in mill, reduce grinding machine internal temperature, and fine powder can be taken away in time; 3, control material flow, balance head and the tail storehouse milling capacity, improve material ball ratio and prevent the effect of anti-classification.
But in actual production operation work, in often occurring, small ball and broken steel ball are stuck in and comb in seam, block seam phenomenon of combing; Along with equipment enlarging development, grate plate thickness increases thereupon, and the abrasive body using the discharge grid plate of traditional structure can cause sticking into comb seam is more difficult to come off, make ball mill punishment in advance less able, draught capacity diminishes, and directly affects ball mill production capacity, and power consumption also rises thereupon simultaneously.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of discharge grid plate for screen analysis material, to reach the object reducing seam card ball phenomenon of combing.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
This is used for the discharge grid plate of screen analysis material, comprises discharge grid plate body, and described discharge grid plate body is provided with fixing hole and seam of combing, and described one end open of combing seam is greater than other end opening, and the opening small end of seam of combing is provided with chamfering.
Further, described comb seam comprises cone seam section and vertical masonry joint section, and described chamfering is located at the outer end of vertical masonry joint section.
The end of described fixing hole is provided with ramp down angle.
Described discharge grid plate is cast-in-block integrative-structure.
Described discharge grid plate adopts abrasion resistant cast steel.
Described seam of combing is for arranged in parallel one group.
The utility model compared with prior art, has the following advantages:
Seam cross sectional shape of combing is designed to tubaeform, and the design of vertical masonry joint section can ensure that initial screen analysis material efficiencies can not reduce, can constant mill inner ventilation, the design of chamfering can effectively avoid putty phenomenon to occur, ensure the stability of mill working, reach the object of stable yields, there is good economic benefit.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is the utility model discharge grid plate structural representation.
Fig. 2 is along A-A sectional view in Fig. 1.
In figure: 1. discharge grid plate body, 11. fixing holes, 12. comb seams, 1201. cone seam section, 1202. vertical masonry joint sections.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
As depicted in figs. 1 and 2, this is used for the discharge grid plate of screen analysis material, comprise the discharge grid plate body 1 of tabular, discharge grid plate body 1 is provided with fixing hole 11 and comb seam 12, fixing hole 11 is symmetrically arranged two, the end of fixing hole 11 is provided with ramp down angle, be convenient to install, discharge grid plate is fixed on discharging support by bolt through fixing hole 11, and on the inwall of fixing hole, sulfuration has rubber layer, vibration is reduced in use procedure, fixing reliable.
Comb seam 12 is one group of mounting hole, and four are arranged side by side and are positioned at side on discharge grid plate body 1, and other four are arranged side by side and are positioned at opposite side on discharge grid plate body, arranged in parallel between comb seam 12; Wherein, concrete seam is wide can require to design according to the grinding process of different client.
Comb seam 12 cross sectional shape is designed to tubaeform, and the one end open of comb seam 12 is greater than other end opening, and the opening small end of seam of combing is provided with chamfering.Be specially, comb seam 12 comprises cone seam section 1201 and vertical masonry joint section 1202, and chamfering is located at the outer end of vertical masonry joint section.Wherein, the design of vertical masonry joint section can ensure that initial screen analysis material efficiencies can not reduce, can constant mill inner ventilation; The design of chamfering can effectively avoid putty phenomenon to occur, and ensures the stability of mill working.
Discharge grid plate is cast-in-block integrative-structure, and alloy wear-resisting cast steel during discharge grid plate adopts, material trademark selects H4 or H9.This structure of seam of combing can not reduce screen analysis efficiency, putty phenomenon effectively can be avoided to occur, can ensure the stability of mill working, reach the object of stable yields, have good economic benefit within the cycle in service life of grate plate.
Discharge grid plate manufacture craft:
First, according to customer process requirement, discharge grid plate structure is designed, make the main core of corresponding mould and core box;
Then, sand mold, core is manufactured according to main core and core box;
Finally, adopt the melting after proportioning according to a certain percentage of suitable foundry returns, steel scrap and other raw material, pour into a mould again, tapping temperature controls at about 1670 DEG C, pouring temperature controls at about 1620 DEG C, it is specifically intended that the speed that temperature declines in the process of cast will control within 8-10 DEG C/min; After moulding by casting, carry out grinding process, heat treatment (quenching temperature controls 1000 DEG C, tempering heating and temperature control 360 DEG C) and knockout process, do flaw detection qualification, particularly in the position of combing seam, prevent penetrating crack.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present utility model and technical scheme are carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
