Abstract

The utility model provides a novel anti-blockage discharging grate plate, which comprises a grate plate body, a cone profile, a material stopping entity, grate holes, a half cavity and an arc plate, wherein the cone profile is a protruding surface of one third of a cone, is inlaid in a raised surface of the grate plate body and is overlaid with the grate plate body; the arc plate is an expansion end formed by extending the cone profile and is connected with a circular arc of a mill cylinder body to form a triangle with cone sides; the material stopping entity is designed to be opposite to the half cavity on the inner side of the cone profile; and the powder flowing area of grate holes is 2.5 times that of the original grate plate grate holes. The novel anti-blockage discharging grate plate has the advantages that the problem of material blockage is solved, the effective ventilation area is increased, the grinding temperature of a mill is reduced, particle distribution of powder is activated, the product quality of finished products is improved, potential safety hazards of a device are eliminated, the labor intensity of operators is reduced, the grate plate is energy-saving and environment-friendly and the like.

Description

A kind of novel anti-putty discharging comb plate

Technical field

The utility model belongs to the drawing mechanism field of building machinery milling equipment, and the discharging comb plate that relates in particular to the big Super-fine grinder machine of a kind of draw ratio is prone to the drawing mechanism of putty, is the design again to the fan-shaped comb plate of primary plane.

Background technology

The milling equipment that generally uses at present is a Super-fine grinder, and is littler than the space that closed circuit mill is shared, invests less relatively.Because it is big that Super-fine grinder has draw ratio, material grinding is long slightly dead time, and the yield rate advantages of higher is so generally be applied.But test and inspection through parameters; Going out feed bin had the grinding phenomenon, learnt that by tailing over curve grinding machine leaves mill tail comb plate end and has the finished powder of 1/4th length ratios to fail in time to get rid of outside the mill approximately, and temperature continues to raise in the mill; Static by high caused abrasive body of temperature and the generation of discharging comb plate; Make and circulate for a long time to form and overstock in its surface of powder absorption that the discharging ability is poorer.Power consumption and apparatus maintenance expense increase when directly causing the grinding machine grinding.Temperature raises in the mill that causes because of putty simultaneously, and it is overweight load, the transmission line of electricity cabinet is heated burns out, and causes personal and device security hidden danger.It is serious simultaneously also to make product cross the grinding phenomenon.

Summary of the invention

The problem that the utility model will solve provides a kind of product that can make and under good ventilation situation, is in the grinding process in the normal temperature range, has improved the novel anti-putty discharging comb plate of the yield and quality of discharging finished product.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of novel anti-putty discharging comb plate; It is characterized in that: comprise comb plate body, cone section, backgauge entity, comb hole, half range cavity and arc; Described cone section; Be the projecting surface of 1/3rd cone, it is embedded on the face of comb plate body protuberance, overlaps with comb plate body;

Said arc, it links to each other with the circular arc of grinding mill barrel for the bellend part that the cone section extends, and forms a side cone triangle;

Described backgauge entity, its design is on the inboard half range cavity opposite of cone section;

Described comb hole, its powder area of passage has increased by 1.5 times than the powder area of passage of former comb plate comb hole design.

Preferably, described novel anti-putty discharging comb plate is the discharging comb plate of high-chromium alloy wear-resistant white cast iron.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, solved the putty problem, and can also increase the available ventilation area, reduced the grinding temperature of grinding machine, reached the normal temperature of assurance product under good ventilation; Reduce cushioning effect and the again grinding phenomenon of material in mill; Effectively avoid adhere to sticking with paste ball and stop up the comb hole, distribution of particles that can also the activation powder improves the yield and quality of discharging finished product; Increase the service life; Eliminated the potential safety hazard of equipment, maintenance cost reduces, and has reduced labor intensity of operating personnel and has had advantage such as energy-conserving and environment-protective.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of novel anti-putty discharging comb plate of the utility model; Comprise comb plate body 1, cone section 2, backgauge entity 3, comb hole 4, half range cavity 6 and arc 5; Cone section 2 is projecting surfaces of 1/3rd cone, and it is embedded on the face of comb plate body 1 protuberance, overlaps with comb plate body 1 and processes novel discharging comb plate; Arc 5 wherein, promptly the bellend of the extension of cone section 2 part links to each other with the circular arc of grinding mill barrel, forms a side cone triangle; Backgauge entity 3, its design is on half range cavity 6 opposites of cone section 2 inboards; Comb hole 4, its powder area of passage has increased by 1.5 times than the powder area of passage of former comb plate comb hole design.

Wherein, novel anti-putty discharging comb plate is the discharging comb plate of high-chromium alloy wear-resistant white cast iron.

The course of work of this instance:

During work; The 90 degree angles that novel discharging comb plate becomes with the node of grinding mill barrel are kicked up powder; Along with the angle of mill running changes, play the effect of quick screening discharging, eliminate powder and prolong the dead angle that grinding machine becomes circular motion to accumulate with the mill consubstantiality at original comb plate.The interconnective bocca string of novel discharging comb plate and grinding mill barrel inner periphery forms a circle together; When grinding machine rotates; Closing on the powder of waiting to get into the discharging state just stirs once when circumference rotates the arc length positions of a comb plate with abrasive body and material are every; Extrude the technical process that screening becomes the screening of initiatively kicking up by original passive rotation; When the moment of charge level was exposed in novel comb plate rotation, abrasive body rolled to the projection of cone section 2 and the angle of comb plate body 1 with material, and leaves the motion process of minimizing screening gradually along the edge of cone section 2 protrusions; Be provided with the backgauge entity 3 of 1/3rd ratios on cone section 2 inboard half range cavity 6 opposites; With the transitional function of picking-up conveying powder, make the interior micro mist of mill receive the influence of exhausting gravitation to make material screen go out to get into the spiral tube rapidly, discharge the external purpose that reaches quick overcurrent conveying of grinding machine.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
