Description

Device for adding solid calcium hypochlorite disinfectant Technical Field The invention belongs to the field of solid disinfectant feeding, and particularly relates to a device for feeding solid calcium hypochlorite disinfectant. Background The existing common calcium hypochlorite adding modes mainly comprise two kinds of devices, namely, 1, a device for adding granular solid calcium hypochlorite disinfectant by using a metering pump after dissolving the granular solid calcium hypochlorite disinfectant by using a medicine dissolving tank, and 2, a device for adding cake/tablet solid calcium hypochlorite disinfectant by using water flow spraying and sucking a dissolving liquid by using a water jet. The former has the following problems: 1. The problems of the medicine dissolving tank are that the dissolution is uneven, the calcium hypochlorite with high concentration is limited in solubility and easy to sink, the upper layer is clear, the lower layer is thick due to insufficient stirring, the concentration extracted by a metering pump is unstable, meanwhile, the sediment and the hardening seriously insoluble impurities at the bottom of the medicine dissolving tank, calcium carbonate and reaction sediment are accumulated for a long time, the effective volume is reduced, the load of a stirring paddle is increased, the clean tank is particularly dirty and particularly tired, and the more the effective chlorine is mixed, the more the medicine is mixed, the frequent medicine dispensing is needed. 2. The check valve and the pump head are frequently blocked by crystallization, and the crystallization is easy to occur on the valve ball and the valve seat, so that the problems of no dosage, neglected flow, idle running of the pump, no medicine discharge, easy blocking of fine residues and crystallization of the pipeline, the elbow and the filter, and the filter screen is blocked after a few days, and the filter screen must be frequently disassembled and washed. 3. The safety and the operation are problems, and the manual dispensing has strong contact irritation to dust and smell to irritate respiratory tracts, skin and eyes. The chlorine is explained separately, the odor in the tank is more obvious when the pressure and the temperature are high and the concentration is high, and the potential safety hazard exists. The maintenance amount is large, the liquid level is watched every day, the medicine is dispensed frequently, and the pump, the valve, the pipeline and the tank are required to be washed frequently. The latter has the following problems: 1. The dissolution step is to spray the inherent defect of dissolution Insufficient dissolution, large concentration fluctuation, only surface wetting by spraying, indissolvable internal tablets/particles, easy formation of hard cores and low dissolution efficiency. Unstable water flow pressure/flow rate and nozzle blockage, which results in the dissolution quantity being negligent and the adding concentration being fluctuated. Calcium hypochlorite contains insoluble impurities (calcium carbonate and calcium chloride), and residues are accumulated on a tray, a filter screen and a bottom chamber after spraying, and the accumulation is thicker. The residue blocks the spray nozzle, the medicine outlet and the return pipeline, so that the dissolution is interrupted and the dosage is suddenly reduced. The medicine bin and the dissolution cavity are not well isolated in dry and wet, and moisture upwards flows to cause the tablets/granules to absorb moisture, harden and adhere to the wall, so that blanking is intermittent. The blanking port is small, no arch breaking device exists, and the manual poking is frequent. After dissolution, the liquid medicine stays in the cavity/pipeline, the illumination and high Wen Jiasu are used for decomposition, the available chlorine is rapidly reduced, and the adding amount is inaccurate. 2. The adding and metering are insufficient in precision and stability, and the scene with low chlorine demand cannot be used The dissolution amount is indirectly controlled by water flow spraying, a water injector is used for adding, the addition amount cannot be accurately set, and the water injector cannot be used in places where only a small amount of disinfectant is needed, such as secondary water supply chlorine supplementing. The crystals are blocked at the positions of the nozzle, the one-way valve, the medicine outlet pipeline and the elbow, so that medicine cannot be discharged, the flow suddenly drops, and the pressure is suppressed. And after stopping the machine, crystallizing the residual liquid medicine, and stopping the machine next time, wherein the machine is required to be frequently disassembled and washed. 3. Control and automation, poor closed loop capability Relies on external instrument, and has low integration level. The built-in residual chlorine sensor is not needed, a third party instrument is required to be externally connected, th
