With the water surface in babinet with lower part outside body；
The drier includes several electrothermal tubes of shell and setting inside housings, the symmetrical two sides of shell point
It is not connected to babinet and cooling body by pipeline；
The cooling body includes cooling tube and around two water-circulating pipes being located on the outside of cooling tube, and the cooling tube is wherein
One end is connect with shell, and the other end is connected to inside the host for attrition process, and the water-circulating pipe uniform close surrounds
Cooling tube is arranged, and wherein one end of two water-circulating pipes is respectively connected to the top and bottom of babinet, is separately positioned on liquid level
Upper and lower both sides.
Compared with the prior art, the present invention has the advantages that：
1, in impurity removal mechanism of the invention in be equipped with the babinet being filled with water, and the air of entrance is first introduced by blast pipe
In water, to remove the dust and other graininess impurity that contain in air by the process of washing, the effect of purification air is played
Fruit avoids introducing impurity in powder product, influences product quality；
2, the present invention is equipped with drier after impurity removal mechanism, including the electrothermal tube being arranged in shell, thus will
To which the air passed through in water is dried, the moisture wherein contained is fully removed, avoids moisture being introduced into powder, cause
Powder water content is exceeded, or leads to line clogging；
3, the present invention is additionally provided with cooling device at drier rear, cooling device be include cooling tube, outside cooling tube
It is arranged with water-circulating pipe, to cool down to internal air by way of water cooling, it is avoided to be caused inside grinder
Ascending air takes away the powder that part does not grind completion, to improve product quality；Two water-circulating pipes difference in the present invention
The top and bottom of babinet are connected to, to circulate the water in babinet as cooling water, improve water resource
Utilization rate has saved cost, improves environment protecting.

Fig. 2 is the schematic diagram of drier of the present invention；
In figure：Babinet 1, shell 2, cooling tube 3, pipeline 4, blast pipe 11, electrothermal tube 21, water-circulating pipe 31.
Specific implementation mode
The technical solution in the present invention is further illustrated with reference to the accompanying drawings and embodiments.
Embodiment：
As shown in Figs. 1-2, the present invention proposes a kind of air-intake device for powder grinding, including sequentially connected removal of impurities
Mechanism, drier and cooling body, the impurity removal mechanism include the babinet 1 for being vertically arranged and being filled with water, the present embodiment raising middle flask
Body 1 is vertical square structure, and 1 top-side of babinet is respectively equipped with two openings, and one of opening passes through pipeline 4 and drying
Mechanism connection, another opening are equipped with air inlet pipe, and in addition to this babinet 1 is sealing structure.The both ends of the air inlet pipe connect respectively
The water surface in 1 outside of babinet and babinet 1 is passed to go back in air inlet pipe to clean outside air importing under water with lower part
Exhaust fan can be set, air inlet effect is improved；In babinet 1 amount of being filled with water be no more than 1 height of babinet 2/3, to avoid air from
It when emerging in water, takes up spray and enters drier, influence other equipment operation.In preferred scheme, the company of being also equipped on babinet 1
It is connected to the water inlet of external water source and the water outlet for draining, it, will be dirty net to carry out changing water to babinet 1 in time
Change is replaced with water, ensures the effect of cleaning dedusting.
