Description
Technical field
The utility model relates to a kind of refrigerant Pre-cooling equipments of freezing crusher.
Background technique
Chinese and Western medicine product, food, condiment, industrial chemicals need to use pulverizer by crushing material, at present when crushing
It is only a kind of that material is crushed using the pulverizer of liquid nitrogen frozen.This pulverizer using liquid nitrogen frozen is due to needing
By the material of room temperature by liquid nitrogen directly cool down after just can be carried out crushing, cause liquid nitrogen usage amount big, crushing it is at high cost, efficiency compared with
It is low, it is not easy to promote.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of reduction liquid nitrogen dosages, improve crushing effect, drop
The refrigerant Pre-cooling equipment of the freezing crusher of low cost.
Purpose of the utility model is realized as follows:
A kind of refrigerant Pre-cooling equipment of freezing crusher, it includes cooling feed bin, the air inlet and whirlpool of the cooling feed bin
Whirlpool air pump connects, and vacuum valve is housed, and be also equipped with suction on cooling feed bin on the pipeline between whirlpool air pump and cooling feed bin
Valve, the bottom of the cooling feed bin control discharging by outlet valve, and the top of cooling feed bin passes through circulating fan and circulation pipe
Road is connected, and the bottom of circulation line is connected at bottom with cooling feed bin, equipped with cooling feed bin heat exchange on circulation line
Device, air inlet valve and exhaust valve, wherein cooling feed bin heat exchanger is used to freeze to cooling feed bin, and again by the wind after cooling
It is passed through in cooling feed bin.
The refrigerant Pre-cooling equipment of the utility model freezing crusher has the advantage that
The refrigerant Pre-cooling equipment of this freezing crusher by before crushing feed bin be added material Pre-cooling equipment, and with pair
Grade semi-hermetic reciprocating refrigeration compressor, using in R507A refrigerant compression agent to heat exchanger, and the wind after cooling recycled logical
Entering in cooling feed bin, material is made to be cooled to subzero 40 DEG C, realizes the pre-cooling of material, material is in brittleness under low-temperature condition,
To make material be easier to crush.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the refrigerant Pre-cooling equipment of the utility model freezing crusher.
In figure: cooling feed bin 1, whirlpool air pump 2, vacuum valve 3, material sucking valve 4, outlet valve 5, circulating fan 6, circulation line 7,
Cooling feed bin heat exchanger 8, air inlet valve 9, exhaust valve 10.
Specific embodiment
Below with reference to the attached drawing in the example of the utility model, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by.Based on the utility model embodiment, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model relates to a kind of refrigerant Pre-cooling equipments of freezing crusher, it includes cooling feed bin 1,
The air inlet of the cooling feed bin 1 is connect with whirlpool air pump 2, and vacuum valve is housed on the pipeline between whirlpool air pump 2 and cooling feed bin 1
3, and it is also equipped with material sucking valve 4 on cooling feed bin 1, after opening whirlpool air pump 2, vacuum valve 3 and material sucking valve 4, material can be in vacuum
It is inhaled under effect in cooling feed bin 1, then supplementing nitrogen to cooling feed bin 1, (nitrogen moisture-free can prevent heat exchanger knot
Dew), so that the pressure of cooling feed bin 1 is reached normal pressure or so.
The bottom of the cooling feed bin 1 controls discharging by outlet valve 5, and the top of cooling feed bin 1 passes through circulating fan 6
It is connected with circulation line 7, the bottom of circulation line 7 is connected at bottom with cooling feed bin 1, equipped with cold on circulation line 7
But feed bin heat exchanger 8, air inlet valve 9 and exhaust valve 10, wherein cooling feed bin heat exchanger 8 is used to make cooling feed bin 1
It is cold, and the wind after cooling is passed through again in cooling feed bin 1, under the action of cooling feed bin heat exchanger 8, realize the pre- of material
Cold, material is cooled to subzero 40 DEG C or so holding regular hours, and material is in brittleness under low-temperature condition, to make material more
It is easy to crush, then by liquid nitrogen dosage can be reduced after being transported to disintegrating apparatus, improves crush efficiency.
After opening whirlpool air pump, vacuum valve and material sucking valve, material can be inhaled under vacuum in cooling feed bin, then
Nitrogen is supplemented to cooling feed bin, the pressure of cooling feed bin is made to reach normal pressure, then opened circulating fan, cooling feed bin heat exchange
Device, air inlet valve, exhaust valve to freeze to cooling feed bin, and the wind circulation after cooling are passed through in cooling feed bin, make object
Material is cooled to subzero 40 DEG C, realizes the pre-cooling of material.
