DETAILED DESCRIPTION

[0014] See also Figure 1 , Figure 1 It is a schematic diagram of the overall structure of the lime dosing device with metering function of the present invention.

[0015] The utility model provides a lime dosing device with a metering function, comprising a silo top dust collector 101, a silo 102, a feed port 103, a pressure safety valve 104, a conical vibrating hopper 105, a feed pipe 106, a rubber elastic tube 107, a wide-mouth feed hopper 108, a dosing metering pump 109, a screw conveyor 110, a ladder 111, a plurality of vibrators 112, a material level switch 113, a stirring tank 114 and a stirring assembly, wherein the silo 102 is divided into a high material level line 115 and a low material level line 116, and the stirring assembly comprises a rotating motor 117, a rotating blade 118, a water inlet pipe 119, a water outlet pipe 120 and an automatic metering device 121.

[0016] According to this specific embodiment, the silo top dust collector 101 is connected to the silo 102 and is located above the silo 102. The feed port 103 is connected to the silo 102 and is located above the silo 102. The conical vibrating hopper 105 is connected to the silo 102 and is located below the silo 102. The pressure safety valve 104 is fixedly connected to the silo 102 and is located above the silo 102. The discharge pipe 106 is connected to the conical vibrating hopper 105 and is located above the silo 102. The shaped vibrating hopper 105 is located below the material storage tank 102. The rubber elastic tube 107 is connected to the feed pipe 106 and is located below the feed pipe 106. The wide-mouth feed hopper 108 is connected to the rubber elastic tube 107 and is located below the rubber elastic tube 107. The dosing metering pump 109 is fixedly connected to the wide-mouth feed hopper 108 and is located on the outer side wall of the wide-mouth feed hopper 108. The stirring tank 114 is provided on one side of the silo 102. One end of the screw conveyor 110 is connected to the wide-mouth feed hopper 108. The other end of the screw conveyor 110 is fixedly connected to the stirring pool 114 and is located above the stirring pool 114. The stirring assembly is arranged on the inner wall of the stirring pool 114. The lime is poured into the silo 102 from the feed port 103, and then the air is filtered by the cartridge-type silo top dust collector 101. The lime in the conical vibrating hopper 105 falls from the discharge pipe 106 into the wide-mouthed feed hopper 108 and passes through the dosing meter. The quantitative feed of the metering pump 109 and the screw conveyor 110 is delivered to the stirring tank 114, and then the stirring assembly is used to stir and mix to complete the production of slaked lime. The pressure safety valve 104 balances the pressure inside and outside the silo 102 to prevent the silo 102 and its ancillary equipment from being damaged. After the pressure returns to normal, the pressure relief valve will automatically restore. Through such a structural design, accurate measurement, stable addition and sufficient mixing of lime are achieved, which solves the shortcomings of the existing technology and improves the effect and efficiency of water treatment.

[0017] The working process of the silo top dust collector 101 is as follows: after passing through the front end flame arrester under the action of negative pressure suction of the centrifugal fan, the smoke is collected through the air duct and enters the filter. The gas is pre-treated before entering the filter cartridge area, and the filtered clean gas is discharged from the exhaust port through the inside of the filter cartridge. As the running time increases, a certain amount of dust will accumulate on the surface of the filter cartridge. At this time, the pulse controller controls the solenoid valve to open according to the set pulse period and pulse interval, sprays high-pressure gas, blows it into the inner cavity of the filter cartridge, shakes off the dust on the surface of the filter cartridge, falls into the dust collecting hopper, and is discharged through the dust collecting box.

[0018] Among them, the lime adding device with metering function also includes a material level switch 113, which is fixedly connected to the material bin 102 and is located on the outer wall of the material bin 102. The material bin 102 is divided into a high material level line 115 and a low material level line 116. After the lime enters the material bin 102, the inventory is always maintained between the high material level line 115 and the low material level line 116, and is controlled by the material level switch 113.

[0019] Secondly, the water inlet pipe 119 is connected to the stirring pool 114 and is located on the outer wall of the stirring pool 114. The water outlet pipe 120 is connected to the stirring pool 114 and is located at the bottom of the stirring pool 114. The automatic metering device 121 is connected to the water outlet pipe 120 and is located on the outer wall of the water outlet pipe 120. The rotating motor 117 is fixedly connected to the stirring pool 114 and is located above the stirring pool 114. The rotating blade 118 is fixedly connected to the rotating motor 117 and is located at the output end of the rotating motor 117. The output end of the rotating motor 117 passes through the stirring pool 114, and the water inlet is controlled by the water inlet pipe 119. After the lime enters the stirring pool 114, the rotating motor 117 is started to drive the rotating blade 118 to stir at high speed, forming a uniform stirring flow field to evenly mix the water and lime. The automatic metering device 121 at the bottom of the stirring pool 114 is used to quantitatively output slaked lime, which is finally discharged from the water outlet pipe 120.

[0020] At the same time, the ladder 111 is fixedly connected to the silo 102 and is located on the outer wall of the silo 102. The ladder 111 is convenient for manual inspection of abnormal conditions and construction.

[0021] In addition, the plurality of rappers 112 are fixedly connected to the conical vibrating hopper 105 and are respectively located on the outer side walls of the conical vibrating hopper 105. The electric rappers 112 are used to prevent and eliminate various blockages and arching phenomena caused by internal friction, deliquescence, electrification, component segregation, etc. of the material in the silo 102.

[0022] When using the lime dosing device with metering function of the present invention, the ladder 111 is set on the top of the silo 102 to facilitate manual inspection of abnormal conditions and construction. The pressure safety valve 104 is set to balance the pressure inside and outside the silo 102 to avoid damage to the silo 102 and its ancillary equipment. After the pressure returns to normal, the pressure relief valve will automatically restore. The top of the silo 102 is connected to the silo top dust collector 101. The dust-laden air brought in by the lime after being poured into the silo 102 is filtered through the silo top dust collector 101. The lime material in the silo 102 is filtered and discharged into the atmosphere. The material level switch 113 is used to measure and regulate the lime material in the silo 102 to always reach a safe production level to avoid excessive or insufficient lime accumulation. The lower part of the silo 102 is connected to the conical vibrating hopper 105 with a flexible tube, and the lower part is connected to the rubber elastic tube 107. The outer wall of the conical vibrating hopper 105 is installed with the rapper 112 to prevent the lime from clogging the pipe mouth. The silo 102 below is connected to each device with a flexible interface to avoid the occurrence of leakage during the rapping process. The structure of the silo 102 is now damaged, and the service life is extended. The wide-mouth feed hopper 108 has a 60° inclination angle, which helps the lime to slide smoothly, avoids the formation of an "arch bridge" phenomenon during the feeding process, ensures continuous and stable material flow, and reduces lime dust. The wide-mouth feed hopper 108 is connected to the dosing metering pump 109 and the screw conveyor 110 below to quantitatively transport the material to the stirring tank 114. The bottom of the stirring tank 114 is equipped with the automatic metering device 121 to achieve accurate metering and control of the lime solution and real-time monitoring. The water output is measured and adjusted, and precise control is performed according to actual needs. The rotating motor 117 drives the rotating blades 118 to stir at high speed. The rotating blades 118 are designed according to fluid mechanics to optimize the mixing effect and form a uniform stirring flow field. The water supply is controlled by the water inlet pipe 119. The bottom of the stirring tank 114 is funnel-shaped, and the solution is collected and discharged from the center of the bottom of the tank. Through such a structural design, accurate measurement, stable addition and sufficient mixing of lime are achieved, which solves the shortcomings of the existing technology and improves the effect and efficiency of water treatment.
