Abstract
The invention discloses a cooling blade for a wood pulverizer. The blade is in a disc shape with blade teeth, and is fixed to a rotor through a mounting groove in the middle portion; a cooling channel is formed in the rotor, and the mounting groove of the blade is of a rectangular structure; the four side walls of the mounting groove are each perpendicularly provided with at least one cooling groove; and the cooling grooves are of columnar structures, and the diameters of the cooling grooves are smaller than the thickness of the blade. The cooling blade is simple in structure, heat generated by friction of the blade can be emitted out in time, and the mechanical performance of the blade is ensured.
Description
Technical field
The present invention relates to size reduction machinery technical field, particularly relate to a kind of wood grinder heat radiation blade.
Background technology
Wood grinder in use, because the density of timber is relatively large, hardness is also relatively large, in crushing process, the produced heat that rubs between rotor mill and timber is larger, make rotor mill generate heat and temperature is higher, long pulverizing, rotor mill and the timber heat produced that rubs can produce certain impact to rotor mill, long-time pulverizing can have influence on the mechanical performance of rotor mill, rotor mill mechanical performance is caused to decline, therefore need to shut down cooling, have impact on the efficiency of pulverizing to a certain extent, reduce crush efficiency.
In order to solve the problem, people, by being provided with cooling duct at internal rotor, are lowered the temperature to rotor by cooling water, but the blade be connected with rotor is out in the cold, and long high temperature action also can affect the mechanical performance of blade.
Summary of the invention
The object of the invention is to overcome the above-mentioned problems in the prior art, a kind of wood grinder heat radiation blade is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of wood grinder heat radiation blade, this blade is discoid in band cutter tooth, be fixed on rotor by the mounting groove at middle part, cooling duct is provided with in described rotor, the mounting groove of described blade is rectangular configuration, respectively on four sidewalls vertically offer at least one radiating groove, described radiating groove is column construction, and diameter is less than the thickness of blade.
Further, respectively on four sidewalls of described mounting groove two radiating grooves are vertically offered.
The invention has the beneficial effects as follows:
Structure of the present invention is simple, and the heat produced that blade can be rubbed distributes in time, ensure that the mechanical performance of blade.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figure 1, a kind of wood grinder heat radiation blade described in the present embodiment, this blade 1 is discoid in band cutter tooth, be fixed on rotor by the mounting groove 2 at middle part, be provided with cooling duct in described rotor, the mounting groove 2 of described blade 1 is rectangular configuration, respectively on four sidewalls vertically offers two radiating grooves 3, described radiating groove 3 is column construction, and diameter is less than the thickness of blade 1.
For the ease of processing radiating groove 3, mounting groove 2 is set to rectangular configuration, and correspondingly the connecting portion of described rotor is also set to rectangular configuration.In crushing process, rub between blade 1 and timber produced heat, carries out heat loss through convection by the air in radiating groove 3 and the lower rotor of temperature, makes the inner heat radiation in time of blade 1, ensure its mechanical strength.
Claims (2)
1. a wood grinder heat radiation blade, this blade (1) is discoid in band cutter tooth, be fixed on rotor by the mounting groove (2) at middle part, cooling duct is provided with in described rotor, it is characterized in that: the mounting groove (2) of described blade (1) is rectangular configuration, respectively on four sidewalls vertically offer at least one radiating groove (3), described radiating groove (3) is column construction, and diameter is less than the thickness of blade (1).
2. a kind of wood grinder heat radiation blade according to claim 1, is characterized in that: respectively on four sidewalls of described mounting groove (2) vertically offer two radiating grooves (3).
