Description
Technical field
The invention belongs to roll squeezer technical field, particularly a kind of bearing block of roll squeezer.
Background technology
Roll squeezer（High-pressure roller mill）Because the advantage of its efficient energy-saving is widely used in the industries such as cement, mine, metallurgy
Grinding system in.But, roll squeezer usually causes system operation unstable because the temperature of base bearing is too high, influence production effect
Rate.When especially base bearing uses grease lubrication, its temperature is even more easily too high.In addition, temperature is too high to substantially reduce profit
Lubrication prescription bearing capacity, or even make lubrication failure, it can also significantly affect the mechanical performance of bearing material, the original assembling of bearing and close
System, directly affects the service life of bearing.
The too high base bearing temperature of roll squeezer is determined by the Cracking Mechanism to material of roll squeezer.Due to material cake exactly
By the attrition crushing between two rollers, double roller work done has larger part conversion for heat energy, and is transmitted by roller
Base bearing is given, so as to cause base bearing temperature to raise；Further, since the pressure suffered by bearing is very big, cause bearing roller
Very big with bearing internal external circle frictional force, friction produces substantial amounts of frictional heat, and then causes base bearing temperature to raise.So roll squeezer
Heat production is itself inherent characteristics, it is difficult to controlled it.How to solve the above problems becomes art personnel and exerts
The direction of power.
The content of the invention
There is provided a kind of roll-in machine bearing with cooling system aiming at above-mentioned problem of the prior art for the purpose of the present invention
Seat, neither influences the advantage of roll squeezer efficient energy-saving, the too high technical problem of base bearing temperature can be effectively solved again.
The purpose of the present invention is realized by following technical proposals：
A kind of roll squeezer bearing block with cooling system, including bearing block, offer bearing hole, its feature on bearing block
It is：The bearing block lateral surface and medial surface are correspondingly arranged in cooling chamber, cooling chamber close to the position of bearing hole cooling
Water flow passage, and two cooling chambers connect to form circulation loop by interface channel, lateral surface cooling chamber is by feed pipe and returns
Water pipe is connected with cooling water source.
Preferably, the top of the bearing block lateral surface and medial surface, bottom are corresponded to respectively opens up cooling groove, and
Gland is installed so as to form cooling chamber on cooling groove, above-mentioned two pairs of cooling chambers are connected by 2 interface channels, and lateral surface
Two cooling chambers connected by connecting tube, wherein lateral surface bottom cooling chamber connection feed pipe, top cooling chamber connection
Return pipe.
Preferably, the gland inner surface is provided with after some gussets, gland and cooling groove cooperation in cooling groove
Form S-shaped cooling water flow conduits, and two ends of the interface channel in cooling water flow conduits of cooling chamber.
Preferably, opening up seal groove along capping rim, load in seal groove between sealing strip, and sealing strip two ends
Mating surface is inclined-plane.
Preferably, the captured area of whole cooling water flow conduits is consistent.
Preferably, the interface channel is opened in cooling chamber close to the side of bearing hole.
Compared with prior art, the beneficial effects of the present invention are：Cooling water is passed through in cooling chamber and carries out circulating cooling
Can most of heat with bearing running, so as to efficiently control the rise of bearing temperature.In addition, seal groove is arranged on gland
On, convenient processing, it is possible to effectively prevent the seepage of cooling water.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is cross-sectional view of the invention；
Fig. 3 is the partial enlarged drawing at A in Fig. 2；
Fig. 4 is the structural representation of gland of the present invention.
Embodiment
With reference to specific embodiments and the drawings, the present invention is further illustrated.
As shown in Figures 1 to 4, a kind of roll squeezer bearing block with cooling system, including bearing block 1, is opened on bearing block 1
Provided with bearing hole 2, top, the bottom of the lateral surface of bearing block 1 and medial surface correspond to and opened up respectively close to the position of bearing hole 2
Cooling groove 3, and gland 4 is installed so that being formed in 2 pairs of closed cooling chambers, cooling chamber has cooling current on cooling groove 3
Road 5.Above-mentioned two pairs of cooling chambers are connected by 2 interface channels 6, and two cooling chambers of lateral surface are connected by connecting tube 7,
So as to form circulation loop.And the cooling chamber connection feed pipe 8 of lateral surface bottom, the cooling chamber connection return pipe 9 on top, is supplied
Water pipe 8 and return pipe 9 are connected with cooling water source, and the cooling water source in the present embodiment is factory cooling pipe network.
In order to further enhance cooling effect, the interface channel 6 is opened in cooling chamber close to the side of bearing hole 2.
The interface channel 6 of cooling chamber is in the two ends of cooling water flow conduits 5.
The inner surface edge of gland 4 is finished for convenience, high convex of a 2mm is left on the inner surface of gland 4
Platform 10.Some gussets 11 are welded on boss 10, formation S-shaped is cold in cooling groove 3 after gland 4 coordinates with cooling groove 3
But water flow passage 5, and the arrangement of gusset 11 ensures that the captured area of cooling water flow conduits 5 is constant.
The processing of seal groove 12 for convenience, along the edge seal groove 12 of gland 4, loads sealing strip in seal groove 12
13, in order to ensure that the mating surface between the two ends of better seal effect sealing strip 13 is 45 ° of inclined-planes, and in the mating surface of sealing strip 13
And fluid sealant is coated on sealing surface, prevent cooling water seepage.
In order to reduce the resistance that cooling water enters interface channel 6, the port chamfering of interface channel 6.
Need to carry out the water pressure test after the completion of above-mentioned bearing block assembling, the water of 0.6MPa hydraulic pressure is passed through into feed pipe, is protected
The time of holding is not less than 0.5 hour, if ne-leakage situation, i.e., qualified.
When in use, the cooling water in factory cooling pipe network is entered in the cooling chamber of bearing block lateral surface bottom by feed pipe
Bottom, be then divided into two bypass flows：Tie point comes the top of lateral surface bottom cooling chamber by cooling water flow conduits,
And bottom in the cooling chamber of lateral surface top is entered by connecting tube；Second branch road is entered on the inside of bearing block by interface channel
In the cooling chamber of face bottom, interface channel of the cooling water along the portion from it of the cooling water flow conduits in it returns to the cooling chamber of lateral surface
In converge with tie point, and bottom in the cooling chamber of lateral surface top is entered by connecting tube.Side surface upper part inside and outside bearing block
2 cooling chambers in flow of cooling water route and bearing block bottom in lateral surface 2 cooling chambers in flow of cooling water road
Line is consistent.Finally, cooling water is flowed out from the cooling chamber on bearing block lateral surface top, and factory cooling pipe network is flowed back to by return pipe,
And most of heat is taken away, so that the base bearing temperature avoided in bearing hole is too high.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
