Description

Anti-caking PAM assists dissolver

Technical field

This utility model relates to a kind of anti-caking PAM and assists dissolver, belongs to paper making equipment field。

Background technology

PAM is domestic conventional non-ionic high polymer coagulant, molecular weight 1,500,000-2,000 ten thousand, and the PAM used in paper production is white granular。In production process, PAM is dissolved in fixing container to carry out, because of its relatively indissoluble solution agitator must be used to make it be uniformly dispersed, but often occurring PAM to dissolve misoperation in course of dissolution causes bigger flocculate and caking to produce, agitator also stirs not open, PAM molecule can be damaged again by the frequency increasing agitator, causes its production and application process to have adverse effect on。

Traditional dissolving method:

1, the agitator in fixing container it is first turned on。

2, in fixing container, 1/3～1/2 clear water is put。

3, after clear water arrives 1/3～1/2 liquid level, by the 1/4～1/3 of Clean water valve pass to standard-sized sheet slowly to water filling in fixing container。

4, adding in fixing container slowly by prior load weighted packed PAM (700g/ bag) manual type, injected clear water limit, limit adds PAM。

5, after PAM has added, standard-sized sheet Clean water valve, after water level arrives the liquid level of process stipulation, close Clean water valve。

6, after agitator waits liquid level arrival process stipulation liquid level, 10min cuts off automatically。

Traditional dissolving step 4, the flow of pouring into of Artificial Control PAM is relatively difficult to apply, and pours the excessive flocculate that necessarily has of flow into and produces with caking；Pour flow into less, cause that production efficiency is low。

Utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provides a kind of anti-caking PAM to assist dissolver, it is prevented that PAM particle flocculation and caking, improves production efficiency。

Anti-caking PAM described in the utility model assists dissolver, including fixing container, setting agitator in fixing container, fixing container upper end sets funnelform trough, fixing connection guide pipe below trough, the fixing container of guide pipe connection, setting gate valve between guide pipe and trough, guide pipe side sets the valve of flat, and valve connects high pressure gas pipeline by ball valve, the guide pipe part near fixing container axis is spigot surface, and spigot surface is obliquely installed。

Operation principle and process:

During work, start agitator, pour PAM granule into trough, open ball valve, valve ejection high velocity air, open gate valve, PAM granule falls in guide pipe and is dispelled by air-flow, making PAM granule uniformly be scattered in fixing container, such agitator can stir evenly when stirring, improves rate of dissolution。

Rotating shaft of stirrer is uniformly fixed and smashes bar, smash and bar sets decorative pattern, the PAM of caking can be broken up when the stirrer is rotated so that it is be easier to dissolve。

Guide pipe inclined downward arranges guide plate, guide plate is comb shape, normal PAM granule can be blown to fixing container opposite side along guide plate by valve, and the PAM granule of bigger caking then from falling between the comb of guide plate and broken bar is smashed, can make PAM granule be scattered evenly。

This utility model is compared with prior art had the beneficial effect that

Anti-caking PAM described in the utility model assists dissolver, uses high pressure gas to dispel PAM granule, improves dissolved efficiency, smash bar and guide plate can be assisted and be broken up by the PAM granule lumpd, and make it be scattered evenly, it is prevented that PAM particle flocculation and caking, improve production efficiency。

Accompanying drawing explanation

Fig. 1 is this utility model embodiment schematic diagram；

Fig. 2 is embodiment illustrated in fig. 1 guide plate schematic diagram。

In figure: 1, agitator；2, fixing container；3, trough；4, gate valve；5, high pressure gas pipeline；6, ball valve；7, PAM granule；8, valve；9, guide plate；10, guide pipe；11, bar is smashed。

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

As depicted in figs. 1 and 2, anti-caking PAM described in the utility model assists dissolver, including fixing container 2, agitator 1 is set in fixing container 2, fixing container 2 upper end sets funnelform trough 3, fixing connection guide pipe 10 below trough 3, the fixing container 2 of guide pipe 10 connection, gate valve 4 is set between guide pipe 10 and trough 3, guide pipe 10 side sets the valve 8 of flat, valve 8 connects high pressure gas pipeline 5 by ball valve 6, and the guide pipe 10 part near fixing container 2 axis is spigot surface, and spigot surface is obliquely installed。

Operation principle and process:

During work, start agitator 1, pour PAM granule 7 into trough 3, opening ball valve 6, valve 8 sprays high velocity air, opens gate valve 4, PAM granule 7 falls in guide pipe 10 and is dispelled by air-flow, making PAM granule 7 uniformly be scattered in fixing container 2, such agitator 1 can stir evenly when stirring, improves rate of dissolution。

Agitator 1 rotating shaft is uniformly fixed and smashes bar 11, smash and bar 11 sets decorative pattern, the PAM of caking can be broken up when agitator 1 rotates so that it is be easier to dissolve。

Guide pipe 10 inclined downward arranges guide plate 9, guide plate 9 is in comb shape, normal PAM granule 7 can be blown to fixing container 2 opposite side along guide plate 9 by valve 8, the PAM granule 7 of bigger caking then from falling between the comb of guide plate 9 and broken bar 11 is smashed, can make PAM granule 7 be scattered evenly。
