Detailed Description

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

As shown in fig. 2-6, to avoid frequent switching of the scraper during dosing. The utility model provides a dosing unit is used in lime slaker feeding, including scraping trigger 3, lime slaker's inlet pipe 1 and connecting 3 unloading ends of scraping trigger and inlet pipe 1's unloading pipe 2, still be provided with feed screw 4 between unloading pipe 2 and the inlet pipe 1 and set up the batching pipe 5 between feed screw 4 unloading end and inlet pipe 1, feed screw 4 passes through the drive of frequency conversion driving piece, it is provided with when the material whereabouts that the inside blade is promoted pivoted detection module to rotate on the 5 inner walls of batching pipe, be provided with in the detection module and carry out the infrared detector 10 that the blade rotated and detected with the ray by the cutting.

Improve on original dosing unit's basis, increase feed screw 4, and regard feed screw 4 as buffer container, through scraping input low sulphate lime in 3 to feed screw 4 of trigger, regard inverter motor 6 as feed screw 4's power supply, and be equipped with reduction gear 7 and increase the moment of torsion, when the low sulphate lime of input is in order to reduce the total sulphur content of the quick lime that gets into in the lime slaker in needs to feed pipe 1, through feed screw 4 through feed screw 5 input low sulphate lime in to feed pipe 1 of batching pipe.

The supplement of the low-sulfate lime in the spiral feeder 4 is realized through the detection assembly, when the low-sulfate lime falls from the batching pipe 5, the blade in the detection assembly is impacted, so that the blade rotates around the mounting shaft of the blade, the infrared detector 10 is cut in the rotating process of the blade, the infrared detector 10 comprises an infrared emitter and an infrared receiver opposite to the infrared emitter, the blade is arranged between the infrared emitter and the infrared receiver, and when the blade rotates and cuts infrared rays, the infrared detector 10 sends a signal to an external control room, namely the fact that the low-sulfate lime in the spiral feeder 4 is sufficient at the moment and works normally is shown; when the infrared detector 10 does not detect the rotation of the blade or detects that the rotation speed of the blade is slow, and the spiral feeder 4 is in an open state, the material in the spiral feeder 4 is used up or insufficient, and the scraper 3 needs to be started at the moment, and the rotation speed of the spiral feeder 4 is increased, so that rapid feeding is realized.

As shown in fig. 4-6, to achieve that the vanes in the sensing assembly are driven to rotate by the low sulphate lime flowing in the batching pipe 5. The detection assembly comprises a mounting box 8 arranged on the side wall of the batching pipe 5, the inside of the mounting box 8 is communicated with the inside of the batching pipe 5, a mounting shaft 11 is rotatably arranged in the mounting box 8, a material blade 12 is arranged on the mounting shaft 11, and the material blade 12 on one side of the mounting shaft 11 is positioned in the batching pipe 5. The low-sulfate lime flowing in the batching pipe 5 can only impact the material blades 12 on one side of the mounting shaft, so that the material blades 12 can be pushed to rotate when the low-sulfate lime flows in the batching pipe 5, and the detection precision of the detection assembly is improved; simultaneously, on the setting of installation box 8 position, installation box 8 is located between unloading pipe 2 and the batching pipe 5, and the low sulphate lime that screw feeder 4 carried flows down on the 5 inside walls of batching pipe that installation box 8 located mostly.

As shown in fig. 4-6, to extend the useful life of the material blades 12. The two ends of the material blade 12 are both fixedly provided with annular reinforcing plates 13, and the reinforcing plates 13 and the mounting shaft 11 are coaxially arranged. Through setting up reinforcing plate 13 for material blade 12 and reinforcing plate 13 form the impeller form entirely, increase material blade 12 and bear the ability of low sulphate lime impact, with this deformation that slows down material blade 12, and then extension material blade 12's life.

As a preferred embodiment of the present invention, lime remains in the installation box 8 for avoiding low-sulphate lime when impacting the material blades 12. The inner bottom surface of the mounting box 8 is an inclined surface, and the bottom end of the inclined surface is connected with the batching pipe 5.

As shown in fig. 4-6, to avoid interference of the infrared detector 10 by dust generated during the blanking of low-sulphate lime. Be provided with on the lateral wall of installing bin 8 communicating box 9, installation axle 11 is located one of communicating box 9 and serves and be provided with around the axis and detect blade 14, infrared detector 10 the sense terminal parallel with install the axis setting of axle 11, just the ray that infrared detector 10 sent can be cut by detecting blade 14. A sealed space, i.e., the inside of the communication box 9, is provided for detection of the rotation of the mounting shaft 11.
