Description
Technical field
The utility model relates to a kind of leakage-proof device, particularly a kind of high-pressure roller mill leakage-proof device.
Background technology
High-pressure roller mill is a kind of disintegrating apparatus being widely used in cement industry, and its operation principle is the rotation by two high pressure roller, carries out fragmentation to material; High-pressure roller mill takes up an area the advantages such as little, energy-conservation, particle size after cracking is thin and treating capacity is large because it has, and is also widely used in more and more in recent years in the industries such as mine, chemical industry, building materials.
When high-pressure roller mill works, the material fallen into from feeding mouth can be subject to the extruding of two high pressure roller, thus be broken, and after material is broken, probably disperse everywhere, the material dropping on edge, two high pressure roller rear and front ends is then easy to eject from high pressure roller rear and front end, thus drops in high-pressure roller mill, affect the work of whole machine, and reduce the handling rate of material.
Common high-pressure roller mill inner space is compact, almost do not add the space of new construction again, if design a kind of baroque leakage-proof device, then probably install less than in high-pressure roller mill, and, usual enterprise deisgn product all will consider manufacturing cost, therefore, designs that a kind of structure is simple, low cost of manufacture, can the device of anti-leak-stopping material to be necessary very much.
Utility model content
The purpose of this utility model be overcome prior art above-mentioned deficiency and provide that a kind of structure is simple, low cost of manufacture, can the high-pressure roller mill leakage-proof device of anti-leak-stopping material.
The technical solution of the utility model is: a kind of high-pressure roller mill leakage-proof device, and comprise two pieces of material baffles, two pieces of material baffles are installed on the rear and front end of secondary breaker roll respectively.
Further, offer the first hole in the middle of described material baffle, the two ends up and down of material baffle offer the second hole respectively.
Further, described first hole is through hole, and the second hole is shoulder hole or clear opening, but is not limited to shoulder hole or clear opening.
Further, the quantity in described second hole is 4 ~ 8, but is not limited to 4 ~ 8.
Further, described material baffle is mounted by means of bolts on secondary breaker roll.
Further, material baffle, by the second hole on material baffle, is fixedly mounted on secondary breaker roll by described bolt.
Further, the end face of described material baffle is circular.
Further, the diameter of material baffle end face is 1.1 ~ 1.2 times of secondary breaker roll diameter; Its reason is: 1, the diameter of material baffle end face determines primarily of the gap between main breaker roll and secondary breaker roll, and the gap between usual main breaker roll and secondary breaker roll is changing value, its interval range is between 0.05 ~ 0.15 times of secondary breaker roll diameter, if the diameter of material baffle end face is less than 1.1 times of secondary breaker roll diameter, then also can there is certain gap between the end face of material baffle and the end face of main breaker roll, material can spill from this gap; When the diameter of material baffle end face is greater than 1.1 times of secondary breaker roll diameter, material baffle is mainly used in preventing material from spilling from the front-end and back-end of two breaker rolls, the end face of its end face and main breaker roll interlocks, like this, even if material is also dispersed everywhere by two breaker rolls fragmentations, also can be blocked by material baffle and get back between two breaker rolls, continue broken; 2, the diameter of material baffle end face directly affects the manufacturing cost of material baffle, therefore this diameter can not be excessive, otherwise manufacturing cost is too high, therefore, draw after every data statistics, the diameter of material baffle end face is preferably 1.1 ~ 1.2 times of secondary breaker roll.
The utility model compared with prior art has following features: 1, structure is simple; 2, low cost of manufacture, material baffle and secondary breaker roll are easy component of machine, and manufacture method is ripe, and only needs hold-down screw to complete assembling; 3, can anti-leak-stopping material, improve the handling rate of material; The end face of material baffle should interlock with the end face of main breaker roll, even if material is also dispersed everywhere by two breaker rolls fragmentations, also can be blocked by material baffle and get back between two breaker rolls, continue broken, fundamentally stop the generation of leaking material, improve the handling rate of material.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.

Detailed description of the invention
embodiment 1
As depicted in figs. 1 and 2: a kind of high-pressure roller mill leakage-proof device, the rear and front end that two pieces of material baffles, 1, two pieces of material baffles 1 are installed on secondary breaker roll 2 is respectively comprised.
The end face of material baffle 1 is circular, and as preferably, in the present embodiment, the diameter of material baffle 1 end face is 1.14 times of secondary breaker roll 2.
Offer the first hole 12 in the middle of material baffle 1, the two ends up and down of material baffle 1 offer the second hole 11 respectively.
As preferably, in the present embodiment, the quantity in the second hole is 4.
Material baffle 1, by the second hole 11 on material baffle 1, is fixedly mounted on secondary breaker roll 2 by bolt 3.
As shown in Figure 3, be installed to by the utility model in high-pressure roller mill 300, the position of secondary breaker roll 2, main breaker roll 301 and position consistency when not installing the utility model, just installed material baffle 1 in the rear and front end of secondary breaker roll 2.
Principle of the present utility model and using method are: after material enters into high-pressure roller mill 300, can directly drop in the gap between main breaker roll 301 and secondary breaker roll 2, because main breaker roll 301 constantly rotates with secondary breaker roll 2, thus fragmentation is carried out to material; The material dropped near two former and later two end faces of breaker roll then can disperse to its shearing force because being subject to breaker roll everywhere, and attempt to eject from the end face of two breaker rolls, now, the material baffle 1 be arranged on secondary breaker roll 2 can block the material particle wanting to eject, in the gap allowing material particle come back between main breaker roll 301 and secondary breaker roll 2, be again broken.
By embodiment 1, demonstrate the handling rate that the utility model can improve material: before not installing the utility model, the handling rate of material is 90%, and after having installed the utility model, the handling rate of material is 97%.
embodiment 2
Embodiment 2 is roughly the same with the embodiment of embodiment 1, and their difference is: the diameter of material baffle 1 end face is 1.17 times of secondary breaker roll 2, and the quantity in the second hole is 8.
By embodiment 2, demonstrate the handling rate that the utility model can improve material: before not installing the utility model, the handling rate of material is 90%, and after having installed the utility model, the handling rate of material is 99%.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
