Abstract
The utility model discloses distributing structure in a kind of Raymond machine main frame, comprise the grinding roller mechanism be placed in cover cylinder, grader installed by described cover cylinder, described grinding roller mechanism is installed on main frame main shaft by plum blossom frame, described plum blossom frame coaxially installs batch mixing pan, above described batch mixing pan, feed well is set, described feed well enters in main frame by cover cylinder level, feed well inside is provided with feed screw structure, or feed well enters in main frame by grader is oblique, the discharging opening of feed well corresponds to the middle part of batch mixing pan.The utility model is by increasing batch mixing pan, whole main frame feeding structure is optimized greatly, not only make bull ring circumference thickness of feed layer even, improve in all kinds of operating mode, shock resistance under the condition of especially processing in high fineness, decrease vibrations that each structural member easily occurs, to loosen and parts occur because of vibrations problems of crack, reach and improve the stability of Raymond machine work and the object of reliability.
Description
(1) technical field:
The utility model relates to raymond mill part of appliance, is distributing structure in a kind of Raymond machine main frame specifically.
(2) background technology:
Raymond machine is one of equipment that in milling equipment, application is the widest, its operation principle centrifugal force that to be the horizontal grinding roller of dependence produce in revolution running and on bull ring rotation roll, between grinding roller and the contact surface of bull ring, material (metal or nonmetallic ore) is ground.
And the charging of traditional Raymond machine offers single charging aperture at its cover cylinder one side lower part, material from then on charging aperture enters main frame inside, and then is milled pulverizing.Because the fineness of actual material and water content, viscosity are different, for ensureing Raymond machine normal sustained service, the Raymond machine of different size all has regulation to require to the pan feeding fineness of material before pan feeding and moisture content, single charging aperture pan feeding simultaneously, will certainly cause main frame mill circumferentially material maldistribution, along with the lifting of Raymond machine output and the expansion of processing fineness scope, the vibrations of Raymond machine in milling process, noise are all the more fierce, and other parts happen occasionally because vibrations causing cracking or damaging.
How when other conditions are constant, ensureing the stable operation of equipment, improve the service life of Raymond machine, is the challenge faced by industry those skilled in the art are badly in need of.
(3) utility model content:
For the deficiencies in the prior art, technical problem to be solved in the utility model be propose a kind of raising mill circumferentially material distributing uniformity Raymond machine main frame in distributing structure.
Distributing structure in the Raymond machine main frame that can solve the problems of the technologies described above, its technical scheme comprises the grinding roller mechanism be placed in cover cylinder, grader installed by described cover cylinder, described grinding roller mechanism is installed on main frame main shaft by plum blossom frame, unlike the prior art described plum blossom frame coaxially installs batch mixing pan, above described batch mixing pan, feed well is set, described feed well enters in main frame by cover cylinder, or feed well enters in main frame by grader, the discharging opening of feed well corresponds to the middle part of batch mixing pan.
In said mechanism, feed well is by mass transport on batch mixing pan, and batch mixing pan is followed main frame main shaft (i.e. plum blossom frame) and rotated together, and material is thrown to surrounding in the rotary course of batch mixing pan, material is comparatively evenly distributed in bull ring circumference, makes the amount of milling of each grinding roller even.
Due to the limited height of cover cylinder, the horizontal setting of the feed well entered in main frame by cover cylinder, for carrying out mass transport, feed well inside is provided with feed screw structure.
The feed well entered in main frame by grader is skewed setting (i.e. charging aperture high and discharging opening is low), and material is by the landing voluntarily of oblique feed well.
Further design, described batch mixing pan is located on plum blossom frame by stay pipe.
The beneficial effects of the utility model:
1, in the utility model Raymond machine main frame distributing structure when original grinding roller, bull ring size constancy and other conditions are constant, by increasing batch mixing pan, whole main frame feeding structure is optimized greatly, not only make bull ring circumference thickness of feed layer even, improve in all kinds of operating mode, shock resistance under the condition of especially processing in high fineness, decrease vibrations that each structural member easily occurs, to loosen and parts occur because of vibrations problems of crack, reach and improve the stability of Raymond machine work and the object of reliability.
2, the utility model makes material possess higher oven dry usefulness in the flowing of main frame inside, namely material is fully contacted with air (especially hot-air) by the process left from batch mixing pan, original moisture content obtains certain oven dry evaporation, ensure that water content requirement during mill, improve Raymond machine to the adaptability of high-moisture material, make Raymond machine stable operation and increasing the service life more.
(4) accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
Figure number identifies: 1, grinding roller mechanism; 2, plum blossom frame; 3, main frame main shaft; 4, cover cylinder; 5, grader; 6, batch mixing pan; 7, feed well; 8, stay pipe; 9, motor reducer.
(5) detailed description of the invention:
Below in conjunction with accompanying drawing illustrated embodiment, the technical solution of the utility model is described further.
In the utility model Raymond machine main frame, distributing structure has two kinds of forms, two identical structure be: the grinding roller mechanism 1 of main frame is placed in cover cylinder 4, grader 5 is installed at the top of described cover cylinder 4, described grinding roller mechanism 1 is installed on main frame main shaft 3 by plum blossom frame 2, and motor reducer 9 drives main frame main shaft 3 to rotate by gear drive; Stay pipe 8 is vertically on plum blossom frame 2 and coaxially installs, and batch mixing pan 6, with being located on stay pipe 8, is provided with feed well 7 above described batch mixing pan 6, and the discharging opening of described feed well 7 corresponds to the middle part of batch mixing pan 6, as shown in Figure 1 and Figure 2.
The difference of the first version of the utility model is: described feed well 7 enters main frame inside by the sidewall of cover cylinder 4, and feed well 7 is horizontally disposed with, and the inside of feed well 7 is provided with feed screw structure, as shown in Figure 1.
The difference of the utility model the second version is: described feed well 7 enters main frame inside from the housing sidewall of grader 5 and the top mouth of cover cylinder 4, the oblique setting of feed well 7 (prerequisite does not interfere with the workpiece of grader 5 inside), the charging aperture of feed well 7 is high and discharging opening is low, as shown in Figure 2.
