Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 1-4, the problem that the water inlet pipe 2 of the feeding device for spraying is easy to deposit and block is solved. The utility model provides a yellow phosphorus workshop boiler tail gas desulfurization sprays and uses feed arrangement, including connecting in connecting box 1 on circulating pump inlet tube 2's expansion end, the water inlet channel is seted up to connecting box 1's bottom, 1 internal rotation of connecting box is provided with the stirring subassembly of cage form, and the axis of inlet tube 2's axis perpendicular to stirring subassembly, coaxial coupling has eccentric wheel 14 in the stirring subassembly, blade length on the eccentric wheel 14 steadilys decrease towards a direction of rotation, and the expansion end mouth of pipe of inlet tube 2 is located eccentric wheel 14 directly over, 1 outside cover of connecting box is equipped with the filter mantle of taking flexible filter screen.

When the water inlet pipe 2 is opened for water absorption, the lime water flows upwards from the bottom of the connecting box 1, the lime water passes through the eccentric wheel 14, the length of the blade on the eccentric wheel 14 is gradually reduced along the clockwise direction, so that the thrust of the water on one side of the long blade is larger, the eccentric wheel 14 is further rotated, the blade with large stress is rotated to the other side of the eccentric wheel 14 and then is pushed by the lime water to rotate to the other side of the eccentric wheel 14, and the reciprocating swing of the eccentric wheel 14 is realized; the eccentric wheel 14 is fixedly connected to the axis of the stirring component and drives the stirring component to swing, and when the lime water flows through the inside of the connecting box 1, the lime water is stirred by the stirring component, so that the lime water entering the water inlet pipe 2 does not contain agglomerated precipitates, and the water inlet pipe 2 is prevented from being blocked; the eccentric wheel 14 is installed at the position facing the nozzle of the water inlet pipe 2 so that the eccentric wheel 14 can maintain a high-speed swing.

The water inlet of the water inlet pipe 2 and the swing of the stirring component are realized in a linkage manner, namely when spraying desulfurization is not carried out, the stirring component is in a static state; usually, the circulating tank is changed with water to remove the lime milk attached to the inside of the water inlet pipe, the water pump and the spraying feeding device.

The filter mantle that establishes at the outside cover of connecting box 1 can play certain filterable effect to the solid sediment in the lime wash, and the filter mantle can be dismantled, consequently after promoting the filter mantle out the surface of water, can wash flexible filter screen.

As shown in fig. 2-4, to effect rotation of the stirring assembly with the eccentric wheel 14. All be provided with on the relative inner wall of connecting box 1 and be used for rotating the connection the mount pad 11 of the axis of rotation of stirring subassembly, the stirring subassembly includes installation axle 13, sets up in the connection pad 12 at installation axle 13 both ends and around the axis distribution of installation axle 13 and connect in the puddler 15 between two connection pads 12, eccentric wheel 14 is fixed to be set up on installation axle 13.

The axis of rotation of stirring subassembly is installation axle 13 promptly, set up the bearing frame on the lateral wall of mount pad 11, and install the bearing, the both ends of installation axle 13 are connected on two mount pads 11 through the bearing rotation respectively, when eccentric wheel 14 atress drives installation axle 13 swing, installation axle 13 drives the puddler 15 swing through connection pad 12, lime wash flows through from the clearance between two adjacent puddlers 15, in-process that lime wash flowed through, puddler 15 stirs lime wash promptly. Of course, in order to ensure that the stirring rods 15 can sufficiently stir all the lime water entering the water inlet pipe 2, the distance between the opposite stirring rods 15 is equal to the distance between the opposite inner walls of the connecting box 1, and meanwhile, a gap is formed between the connecting disc 12 and the mounting seat 11, so that the lime water entering the water inlet pipe 2 can be sufficiently stirred as a whole.

As the utility model discloses preferred embodiment, the support bearing who is avoiding installation axle 13 is adhered to by more sediment, leads to the bearing to damage. The installation axle 13 is sleeved with a sealing ring for sealing the bearing in the installation seat 11. The sealing washer sets up in the opening part of the bearing frame of mount pad 11 lateral wall, seals the bearing, prolongs the life of bearing.

As shown in fig. 3, to further improve the stirring efficiency. The cross section of the stirring rod 15 is not circular, and the stirring rod 15 is rotatably connected between the two connecting discs 12. Puddler 15 is driven by connection pad 12 and is swung around installation axle 13 for puddler 15 can the rotation, and like this, further improvement the effect to lime wash stirring.

As shown in fig. 1-2, to accelerate the flow rate of the water at the stirring assembly and to direct the lime water flowing through the stirring assembly. The connection box 1 is trapezoidal. After the lime water flows into the connecting box 1, the internal cross-sectional area of the connecting box 1 is continuously reduced, so that the flow speed of the lime water is faster, and the lime water impacts the blade of the eccentric wheel 14, so that the swinging rotating speed of the eccentric wheel 14 is improved.

As shown in fig. 1, to reduce the precipitation entering the inlet pipe 2, the subsequent shower pipes after the circulation pump are blocked. The filter mantle includes the steel skeleton 3 of cube structure and sets up in steel skeleton 3's clearance flexible filter screen, 3 slip caps of steel skeleton are located on the inlet tube 2. When breaking up the sediment of stirring subassembly in to lime aquatic, set up flexible filter screen, can attach to the lime breast of part on flexible filter screen, and filter mantle slidable connects on inlet tube 2, can carry out the surface of water with the filter mantle along inlet tube 2, washes the filter mantle.
