Description

A kind of timber pulverizer

Technical field

The utility model relates to a kind of papermaking equipment, particularly a kind of timber pulverizer.

Background technology

Existing paper mill is mechanization day by day all, reduces manual operation to save the labour and to raise the efficiency in whole production line.Need and form paper pulp with raw material pulverizing when papermaking, this process generally is that timber is pulverized earlier.The process of pulverizing generally comprises: the processing of earlier timber being peeled, to cut into slices then, and slurrying is carried out in the pulverizing of will cutting into slices again again after the pulverizing.

Because the comminution ratio of timber is difficulty, existing crushing process all is to adopt beater grinder, can only the sheet sheet material that obtain after the section is cracked.Because cracked effect extreme difference therefore must be through long boiling, so that wood shavings forms wood pulp.And in the process that cooks, need to add a large amount of NaOH.And the NaOH that gives off contaminated environment greatly, and the process of boiling can highly energy-consuming, therefore makes paper industry become the industry of a high pollution highly energy-consuming.

Therefore how wood powder being broken into powder more in small, broken bits to reduce the boiling flow process time, is the problem that is always perplexing paper-making industry.

The utility model content

In order to solve the problem that timber can't be pulverized in the prior art, the utility model embodiment has proposed a kind of timber pulverizer, and the existing beater grinder of can comparing has better crushing effect.Described technical scheme is as follows:

The utility model embodiment has proposed a kind of timber pulverizer, comprises crushing chamber and pulverization roller, it is characterized in that, described pulverization roller surface is provided with spiral helicine blade, and described blade comprises the body of a V-shape, and described blade body is fixedlyed connected with described pulverization roller.

Preferred as technique scheme, described pulverization roller vertically is provided with.

Preferred as technique scheme, described crushing chamber is provided with feeding mouth, and described feeding mouth is arranged at the top of described crushing chamber, and the internal diameter at described crushing chamber top is greater than the internal diameter of described crushing chamber bottom.

Preferred as technique scheme, described crushing chamber is provided with feeding mouth, described feeding mouth is arranged at the top of described crushing chamber, and the internal diameter at described crushing chamber top equates with the internal diameter of described crushing chamber bottom, and the diameter at described pulverization roller top is less than the diameter of described pulverization roller bottom.

Preferred as technique scheme, the blade tip of described pulverization roller is a zigzag.

Preferred as technique scheme, the spacing of the sawtooth on described pulverization roller top is greater than the spacing of the sawtooth of described pulverization roller bottom.

Preferred as technique scheme, described discharging opening is arranged at the bottom of described crushing chamber.

The beneficial effect of the technical scheme that the utility model embodiment provides is: the utility model embodiment further pulverizes the broken wood chip after pulverizing through beater grinder by pulverization roller.Wood powder can be broken into powder art more in small, broken bits like this, to reduce the boiling flow process time, the saving energy also reduces and pollutes.

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.

Preferred embodiment of the present utility model has proposed a kind of timber pulverizer, its result comprises crushing chamber 1 and pulverization roller 2 as shown in Figure 1, and pulverization roller 2 surfaces are provided with spiral helicine blade 3, blade 3 comprises the body of a V-shape, and described blade body is fixedlyed connected with pulverization roller 2.Wood powder can be broken into powder more in small, broken bits like this, to reduce the boiling flow process time, the saving energy also reduces and pollutes.Simultaneously, the bottom of blade 3 has certain thickness and most advanced and sophisticated sharp-pointed, makes blade 3 form the body of a V-shape, can improve the intensity of blade 3 like this, prevents to cause blade to fracture when long-time the use.

Preferably, as shown in Figure 1, pulverization roller 2 vertically is provided with.

Preferably, as shown in Figure 2, be zigzag at the blade tip of pulverization roller 2, be provided with sawtooth 21.Can further improve crushing effect like this to timber.Wherein, the spacing of the sawtooth 21 on pulverization roller 2 tops is greater than the spacing of the sawtooth 21 of pulverization roller 2 bottoms.This is that the bigger sawtooth of employing spacing can be gone into overdrive, and reduces the wearing and tearing to sawtooth because bigger in the timber measurement on pulverization roller 2 tops.And that the timber in pulverization roller 2 bottoms can compare is less, adopts fine and closely woven sawtooth to pulverize timber thinner.

Preferably, as shown in Figure 1, crushing chamber 1 is provided with feeding mouth 11, and feeding mouth 11 is arranged at the top of crushing chamber 1, and crushing chamber 1 upper part diameter becomes a truncated cone shape greater than the diameter of crushing chamber 1 bottom.

Like this can be so that bigger material can enter in the crushing chamber 1 from feeding mouth 11 very easily, and under the effect of gravity, fall.In dropping process, pulverization roller 2 can constantly be pulverized bigger material gradually, thereby reduces the volume of material when arriving the bottom.

And realize this purpose mode can also for, crushing chamber 1 is arranged to the top and bottom internal diameter equate, and pulverization roller 2 is arranged to up-thin-low-thick form (not shown).Be the diameter of the diameter at pulverization roller 2 tops less than pulverization roller 2 bottoms.Can be processed forr a short time by pulverization roller 2 gradually equally like this so that material falls in the process of pulverizing gradually.

Preferably, also comprise discharging opening 12 in the bottom of crushing chamber 1.

By the foregoing description as can be seen: the utility model embodiment further pulverizes the broken wood chip after pulverizing through beater grinder by pulverization roller.Wood powder can be broken into powder more in small, broken bits like this, to reduce the boiling flow process time, the saving energy also reduces and pollutes.Adopt the blade of V-shape simultaneously, can prevent from when long-time the use, to cause blade to fracture.And in order to improve the effect of pulverizing, the utility model vertically is provided with pulverization roller, and crushing chamber is set to wide at the top and narrow at the bottomly, or pulverization roller is set to up-thin-low-thick.Like this can be so that the bigger material of volume can enter in the crushing chamber smoothly, and crushed between the inwall of pulverization roller and crushing chamber, and constantly fall.In dropping process, be subjected to the extruding of pulverization roller, further crushed.Can make and tear timber in its unity and coherence in writing that gos deep into timber and the blade of blade is arranged to zigzag, to improve crushing effect.And the spacing of the sawtooth on pulverization roller top is greater than the spacing of the sawtooth of pulverization roller bottom.This is that the bigger sawtooth of employing spacing can be gone into overdrive, and reduces the wearing and tearing to sawtooth because bigger in the timber measurement on pulverization roller top.And that the timber in the pulverization roller bottom can compare is less, adopts fine and closely woven sawtooth to pulverize timber thinner.

The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
