Abstract
The utility model discloses a blanking mechanism for a lime bin, which comprises air inlet pipes, telescopic joints, electromagnetic valves and backwashing pipes. Open holes are distributed on the bin, the telescopic joints are mounted on the open holes, the backwashing pipes mounted on the telescopic joints extend into the bin, the depths of the parts, which extend into the bin, of the backwashing pipes can be adjusted by the aid of the telescopic joints, the electromagnetic valves are mounted on the backwashing pipes, and the backwashing pipes are connected into a high pressure air source by the air inlet pipes. The blanking mechanism can eliminate bridging of lime powder, and solves the problem of preparation concentration of lime emulsion.
Description
Technical field
It is relevant that the utility model relates to the lime feed bin blanking mechanism that water treatment lime prepares in the interpolation process.
Background technology
In giving water treatment, some source hydromining reservoir water, its water quality slant acidity for reaching the PH standard of tap water, needs to add alkali (as calcium hydroxide) and improves PH.The existing lime preparation system that adopts, at first with the lime raw material storage in lime feed bin 1 (as shown in Figure 1), be sent in the lime dissolving vessel by screw then and dissolve, render to each release position after add pump.
This lime preparation system in use because problem such as the ridity of domestic lime powder is not high causes lime powder in the feed bin of storage arch formation to take place, and causes the lime blanking inhomogeneous, thereby influenced the compound concentration of lime slurry.
Therefore, the present invention is directed to this problem the lime feed bin is improved, this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of lime feed bin blanking mechanism that can eliminate the lime powder arch formation, solves the problem of the compound concentration poor stability of lime slurry.
To achieve these goals, the solution that adopts of the present utility model is:
Lime feed bin blanking mechanism comprises inlet pipe, telescopic joint, magnetic valve, recoil tube; On feed bin, lay perforate, telescopic joint is installed in the perforate; Recoil tube is contained in and stretches into feed bin inside on the telescopic joint, can regulate the degree of depth that recoil tube stretches into feed bin inside by telescopic joint, and magnetic valve is installed on the recoil tube, and recoil tube is connected in the high-pressure air source by inlet pipe.
Described perforate quantity is 8, is laid in up and down on two circumference, divides upper and lower two-layerly, and every layer is 4, and adjacent apertures equidistantly distributes.
Described perforate is arranged on the tapered portion of feed bin.
Described all inlet pipe are external on the same high-pressure air source.
Described recoil tube extends the termination sealing of feed bin inside, offers a plurality of pores on all around, generally is advisable with 5～6.
Described magnetic valve connects outside PLC (logic control element), by PLC control keying state.
After adopting the utility model, high-pressure air different depths place in the lime feed bin regularly recoils, and realizes similar churned mechanically effect, reaches to destroy the lime powder arch formation.Each perforate can be installed recoil tube on telescopic joint as the rapping point, and high pressure air feeds the lime feed bin by inlet pipe and solenoid control.The control air intake system structure is reasonable in design, efficiently solves the uneven production difficult problem of feed bin blanking, has guaranteed the compound concentration of lime slurry, both saves time, laborsaving, does not pollute surrounding environment again, guarantees effective control of water quality pH value.In addition, by PLC control magnetic valve, realize remote manual control and control automatically.
Figure of description
Fig. 1 is the structural representation of existing lime feed bin;
Fig. 2 is the structural representation of the utility model preferred embodiment.
Embodiment
In conjunction with Fig. 2, preferred embodiment is described in further details to the utility model.
Lime feed bin blanking mechanism comprises lime feed bin 1, recoil tube 2, telescopic joint 3, magnetic valve 4, inlet pipe 5.
Around the tapered portion 11 of lime feed bin 1, have 8 perforates 12, the position of 8 perforates is laid in up and down on two circumference, form two-layerly up and down, 4 every layer, the perforate 12 between adjacent is equidistantly distribute (only expressing wherein two perforates 12 on same circumference among Fig. 2).Welding steel telescopic joint 3 in perforate 12, at telescopic joint 3 recoil tube 2 is installed, recoil tube 2 stretches in the lime feed bin 1, can regulate by telescopic joint 3 and go deep into recoil tube 2 length in the lime feed bin 1, generally be about 10CM and be advisable, the top seal of recoil tube 2 also leaves a plurality of pores 31.
Recoil tube 2 storehouse outside part are installed magnetic valve 4 backs and inlet pipe 5 is joined, and all inlet pipe 5 also are connected on the same high-pressure air source.Magnetic valve 4 connects outside PLC, controls its keying state by PLC.
The utlity model has remote manual, automatic controlled function.Under the remote manual master mode, middle control watchstander can carry out independence keying operation to any in 8 magnetic valves 4, and a certain zone in the lime feed bin 1 is repeatedly recoiled, stirred; Under automatic control mode, all magnetic valve 4 is all by the PLC time variable control, realize and the interlock of lime compounding system, and open and close in turn in sequence, different sites to lime feed bin 1 carries out the high-pressure air recoil, stirs, finish just until preparation and to stop, destroying the lime arch formation in the feed bin effectively, guarantee that the lime blanking is even.
