Description of the drawings
Fig. 1 is the overall schematic of the polyacrylamide dissolver of the utility model；
Fig. 2 is the overall schematic of feed belt shown in FIG. 1.
Specific implementation mode
In order to keep the object, technical solution and advantage of the polyacrylamide dissolver of the utility model more clear bright
In vain, below in conjunction with specific drawings and the specific embodiments, the present invention will be further described in detail.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
Referring to Fig. 1, the present embodiment provides a kind of polyacrylamide dissolvers comprising tank body 100, feed belt 200,
Water inlet pipe 300 and agitating device 400.
Tank body 100 is usually cylindrical tank, and material can be the materials such as fiberglass, stainless steel.Tank body is dissolving dress
The dissolving of the major part set, polyacrylamide is completed in tank body.The size of tank body can design according to actual needs.
Polyacrylamide adding set and solute adding device are provided on tank body.The solute of the present embodiment is water.In the present embodiment
Water inlet pipe 300 is provided with above tank body, the inside of tank body is preferably stretched into the water outlet of water inlet pipe 300.
Feed belt 200 is for conveying in polyacrylamide to tank body.Since the dosage of polyacrylamide is very big, because
This polyacrylamide is typically to be added at bag.If directly the polyacrylamide of whole bag, which is directly added into tank body, to make
At the incomplete problem of polyacrylamide amine solvent, therefore generally requires and control its addition.Current many chemicals dosing plants are logical
Weighing balance is crossed to control the addition of polyacrylamide, but since the dosage of polyacrylamide is very big, and in sewage disposal
The concentration requirement of polyacrylamide is wider, the problem for having technique cumbersome using weighing balance.The present embodiment is proceeded from the reality, and is used
Feed belt conveys polyacrylamide；Simultaneously in order to control the addition of polyacrylamide, it is arranged in the top of conveyer belt 200
Patter 210, polyacrylamide can only pass through below patter after patter is arranged, and the height of patter can be adjusted, pass through tune
The height of section patter can substantially adjust the addition of polyacrylamide, while can ensure that the uniform of polyacrylamide adds
Enter.Setting weighing balance can not had to using the feed belt with patter of the present embodiment, comparatively can save equipment throwing
Money.
Agitating device 400 is additionally provided in the tank body of the present embodiment, setting agitating device can promote polyacrylamide molten
Solution avoids polyacrylamide from generating bonding.But the rotating speed of agitating device should be limited to 50~100 revs/min.
Please with further reference to Fig. 2, the vertical range h of the patter 210 and the feed belt 200 is 1~6 millimeter.This
The distance between patter in embodiment and feed belt can move.Polyacrylamide can be simply adjusted after setting patter
Addition, while the step of also need not manually smoothing out.
Further, referring to Fig. 1 and Fig. 2, the feed belt 200 in the present embodiment is obliquely installed, the patter 210
Discharge end distance m with the feed belt 200 is 10~30 centimetres.The discharging of patter 210 and the feed belt 200
The distance m at end is 10~30 centimetres of additions that can not only control polyacrylamide, and can be to avoid excessive polypropylene
Before amide is collected at patter.
More preferably, the angle of inclination of the feed belt 200 is less than 20 degree.Setting avoids generating patter larger in this way
Pressure.
Preferably, as another embodiment, referring to Fig. 1, the agitating device 400 in the present embodiment includes
Motor 410, agitating shaft 420 and the blade being arranged on the agitating shaft；The upper end 420 of the agitating shaft and the motor 410
Connection, the lower end of the agitating shaft 420 is fixed on the bottom of the tank body 100.The both ends of agitating shaft in the present embodiment are fixed
Agitating shaft can be avoided to shake.
Preferably, referring to Fig. 1, the blade includes the first blade 430 being arranged in the centre position of the agitating shaft 420
With the second blade 440 in the lower end of the agitating shaft 420 is set.The first blade and the second blade, which is arranged, can avoid polypropylene
Amide bonds in tank body.
More preferably, the diameter of second blade 440 is less than the diameter of first blade 430.Setting is ensureing in this way
The load of motor can be suitably reduced while mixing effect.
As a kind of more preferably embodiment, referring to Fig. 1, the bottom 110 of the tank body 100 in the present embodiment be to
The arc of lower protrusion, protrusion of second blade 430 close to the bottom of the tank body 110.That is the second blade master
If for stirring the polyacrylamide for being deposited on tank base, arc-shaped bottom is arranged in tank body, can be made undissolved
Polyacrylamide concentration is deposited in the protrusion of tank base；And the setting of the second blade can then be promoted into this part at this
The dissolving of polyacrylamide, to improve the utilization rate of polyacrylamide.
Further, the position of the curved bottom on the side wall of the tank body 100 close to the tank body is provided with outlet tube
102.Metering pump can also be set on outlet tube.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be subject to claim.
