It asks；Liquid nitrogen, which realizes, to be recycled, and save the cost is more advantageous to, and reduces energy consumption.
Further, powder material finished product, the whirlwind point are mixed into the gaseous nitrogen atmosphere obtained in order to avoid cyclone separator
From bag filter is arranged between device and compressor.It thus can use bag filter to be dusted powder material finished product
Processing.
Further, nitrogen recycling tank is set between the bag filter and compressor.Stop in the deep cooling crush machine
After work, the nitrogen of a large amount of low temperature is also had in the component and pipeline of deep cooling crush machine, if being directly discharged into atmosphere, it will make
At the waste of low temperature nitrogen.This waste includes that separation air obtains the cost of nitrogen and carries out low-temperature treatment to isolated nitrogen
Cost.
Further, pressure sensor is set in the low temperature grinding machine.Pressure sensor can measure material freezing chamber in real time
Interior atmospheric pressure, in this way can be when the volume of nitrogen reaches certain preset value, the information that pressure sensor is reflected,
Controller is fed back, and then controls the open and close of solenoid valve.
Compared with prior art, the invention has the following advantages:
1, the present invention is to treat comminuting matter using liquid nitrogen to cool down and freeze to reach material smashing institute
The brittleness needed, nitrogen are the main components of air, therefore resourceful and convenient for separation, after liquid nitrogen cools down material
Itself become the nontoxic gas of colorless and odorless, avoid the pollution to powder material finished product, in addition nitrogen or a kind of anti-well
Oxidant can prevent powder material finished product to be oxidized and go bad；
2, the connection of compressor, bag filter and associated pipe realizes the recycling of nitrogen, more favorably
In economizing on resources, energy consumption is reduced, reduces cost；
3, nitrogen recycling tank can recycle low temperature nitrogen when the deep cooling crush organ closes, preferably energy saving, drop
Low energy consumption；
4, the application of pressure sensor is so that deep cooling crush machine realizes that liquid nitrogen container unlatching is more intelligent.

In figure: 1, middle roll-over；2, pressure sensor；3, adhere to vibrator；4, low temperature grinding machine；5, liquid nitrogen container, 6, Luo Cifeng
Machine；7, cyclone separator；8, bag filter；9, compressor；10, nitrogen recycling tank；11, powder conveying pumps；12, finished bin.
Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawings of the specification.
Such as Fig. 1, a kind of solid poly carboxylic acid series water reducer cold grinding deep cooling crush machine, comprising: 1, middle roll-over；2, attachment is vibrated
Device；3, low temperature grinding machine；4, pressure sensor；5, liquid nitrogen container, 6, roots blower；7, cyclone separator；8, bag filter；9, it presses
Contracting machine；10, nitrogen recycling tank；11, powder conveying pumps；12, finished bin.
Middle 1 upper feed inlet of roll-over is connected with flaker feed opening, middle roll-over lower ending opening by connecting line with it is low
Warm grinding machine 3 connects, and equipped with attachment vibrator 2, low temperature grinding machine 3 is connect by connecting line with roots blower 6；Roots blower 6
It is connect by connecting line with cyclone separator 7,7 upper end of cyclone separator connects bag filter 8, and bag filter 8 passes through
Connecting line is connected to nitrogen recycling tank 10,8 connect compressor 9 of bag filter, and compressor 9 passes through connecting line and middle roll-over
1 connection, cyclone separator 7 lower end dust outlet connection powder conveying pump 11, powder conveying pump 11 by connecting line at
Product storehouse 12 is connected to.
The best powder for reaching material is cooled down to bulk polymerization solid sheet poly carboxylic acid series water reducer using liquid nitrogen
It is smashed and ground after broken state, realizes and heat sensitive material is smashed and ground, guarantee that the fineness of material meets the requirements；It is right
The sheet material of flaker discharging is directly crushed, and the waste of the cooling capacity is avoided, and reduces energy consumption, is more conducive to grinding and powder
Broken efficiency.Liquid nitrogen, which realizes, to be recycled, and save the cost is more advantageous to, and reduces energy consumption.Compressor, bag filter and
The connection of associated pipe realizes the recycling of nitrogen, is more advantageous to and economizes on resources, and reduces energy consumption, reduces cost.
As Fig. 1 prevents material to be comminuted because of freezing to increase the patency of the blanking to be comminuted after freezing
Or size itself interferes blanking, middle 1 lower part of the roll-over setting attachment vibrator 2.
Such as Fig. 1, nitrogen recycling tank 10 is set between the bag filter 8 and compressor 9.Stop in the deep cooling crush machine
After only working, the nitrogen of a large amount of low temperature is also had in the component and pipeline of deep cooling crush machine, if being directly discharged into atmosphere, it will
Cause the waste of low temperature nitrogen.This waste includes that separation air obtains the cost of nitrogen and carries out at low temperature to isolated nitrogen
The cost of reason.
Such as Fig. 1, the low temperature grinding machine 3 is interior to be arranged pressure sensor 4.Pressure sensor 4 can measure material freezing in real time
Indoor atmospheric pressure can control solenoid valve by controller when the volume of nitrogen reaches certain preset value in this way
Switch.
The technical scheme adopted by the invention to solve the technical problem further include:
As shown in figure 1, a kind of breaking method using above-mentioned solid poly carboxylic acid series water reducer cold grinding deep cooling crush machine:
Step 1: in the case where being added without material to be comminuted, making low temperature grinding machine, roots blower, cyclone separator, cloth bag
The air in deep cooling crush machine is discharged in deduster, liquid nitrogen container and compressor operating；
Step 2: flaker conveyer belt is freezed for chip solid polycarboxylic-acid to be comminuted by the rotary-belt of two-layer platform
Water-reducing agent is sent to middle roll-over, and Open valve, which is sent to low temperature grinding machine, when middle roll-over material stock about 3/4ths carries out deep cooling crush, low temperature
The nitrogen to gasify in grinding machine separately has part warp by roll-over and low temperature grinding machine in the return of compressor compresses rear portion lease making connecting line
Connecting line returns to nitrogen recycling tank；
Step 3: meet the powder material finished product of fineness requirement, under the action of roots blower, into cyclone separator into
The separation of row gaseous nitrogen atmosphere and powder material finished product；
Step 4: powder material finished product is under the action of powder delivery pump, into finished bin.
The material for not meeting size is handled by low temperature grinding machine 3, is continued to grind and be crushed in low temperature grinding machine；Crush symbol
The material for closing size, which is passed through, enters cyclone separator 7 by the negative pressure of roots blower 6, carries out the separation of gaseous nitrogen and powder, separation
Powder from the lower end of cyclone separator 7, punishment is separated out, gaseous nitrogen enters compressor 9 by pipeline and bag filter 8 and compresses
After cooling, middle roll-over 1 is again introduced into material frozen cooling, another part nitrogen enters nitrogen recycling tank 10；Due to from whirlwind
Powder material finished product obtained in separator 7 absorbs the cooling capacity of liquid nitrogen during grinding, therefore its temperature is very low, from
The powder material finished product come out in cyclone separator 7, is sent by powder delivery pump 11 to finished bin 12.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not whole embodiments of the invention, not to limit
The system present invention, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in
Within protection scope of the present invention.
