Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sewage treatment drug stirring and feeding device. Background Technique

[0002] In the process of sewage treatment, drugs are used for mixing to accelerate the sedimentation of impurities in the sewage or the reaction removal of internal harmful components. Generally, for the mixing of conventional sewage drugs, multiple drugs need to be preliminarily mixed and stirred first, and then directly manually introduced into the sewage by the operator for corresponding pretreatment reactions. However, this step-by-step method of mixing, transporting, introducing, and treating the sewage not only reduces the efficiency of sewage treatment, but also requires the operator to constantly pay attention and continuously input the drugs during the treatment process due to the flow of the sewage, which affects the treatment effect of the drugs mixed by the operator. At the same time, when the drugs are directly put into the sewage, it is difficult to fully contact and react with the sewage, resulting in low mixing efficiency after the drugs enter the sewage, and further affecting the sewage treatment effect. Content of the Utility Model

[0003] The utility model mainly solves the technical problems existing in the prior art, and thus provides a sewage treatment drug stirring and feeding device that is convenient for the mixing and stirring efficiency of drugs, ensures the reaction effect between the sewage and the drugs during the flow of the sewage, and effectively improves the sewage treatment speed.

[0004] The utility model is a sewage treatment drug stirring and feeding device, which includes a drug cylinder, a filter tank arranged on the side of the drug cylinder, and a partition connected below the drug cylinder. A stirring cavity is arranged inside the drug cylinder, and a mixing cavity communicated with the filter tank is arranged below the partition. A feeding port and a feeding cylinder communicated with the stirring cavity are arranged on the outer surface of the drug cylinder. A rotating shaft passing through the partition is movably connected to the center of the drug cylinder. A driving mechanism for driving the rotating shaft to rotate is connected above the drug cylinder. Stirring blades and spiral blades are connected to the outer surface of the rotating shaft in the stirring cavity. The end of the rotating shaft is located in the mixing cavity and is connected with a paddle. A medicine outlet pipe communicating the stirring cavity and the mixing cavity is arranged on the surface of the partition, and an electromagnetic valve is arranged in the center of the medicine outlet pipe. A liquid level gauge electrically connected to the electromagnetic valve is arranged in the center of the drug cylinder. A sewage pipe is communicated above the side of the filter tank. A support net is connected inside the filter tank, and a filtering element is arranged above the support net inside the filter tank. A liquid inlet cavity communicated with the mixing cavity is arranged below the support net inside the filter tank.

[0005] Preferably, the stirring chamber and the mixing chamber are respectively arranged on the upper and lower sides of the partition board. The liquid level detector is located in the center of the stirring chamber, and a baffle connected to the inner surface of the medicine cylinder is arranged inside the stirring chamber. The liquid level detector is used to detect the liquid medicine content inside the medicine cylinder, so as to facilitate timely addition of medicine. The partition board can separate the stirring chamber from the mixing chamber, so as to facilitate rapid stirring of the liquid medicine and full mixing with the sewage. At the same time, the baffle disrupts the stirring of the medicine, so as to improve the uniformity and sufficiency of the medicine stirring process. The liquid level detector can be a differential pressure liquid level detector or a water level sensor.

[0006] Preferably, the stirring blades are connected above the spiral blades, and the distance between the stirring blades and the partition board is less than the distance between the upper surface of the baffle and the partition board. There are more than two baffles. The height of the baffle above the stirring blades completely blocks and disrupts the medicine inside the medicine cylinder. The spiral blades can drive the liquid medicine in the center to rise or fall, and the stirring blades can drive the liquid medicine to mix disorderly. The blocking of the baffle improves the mixing effect of the liquid medicine.

[0007] Preferably, the filter tank is connected to the side of the medicine cylinder. The civil air defense opening is communicated above the filter tank. A ladder is connected to the inner surface of the filter tank. A support net is connected to the center of the filter tank. The filter element is arranged above the support net, so that the user can enter the filter tank through the civil air defense opening and descend to the bottom of the filter tank for maintenance or replacement of the internal components of the filter tank. At the same time, the support net is provided to support the filter element, so that the sewage can enter the filter tank and be filtered by the filter element and the support net after entering the filter tank.

[0008] Preferably, the diameter of the civil air defense opening is greater than 80 cm, and a protective cover is covered above the civil air defense opening. The filter element is filter stones and fine sand arranged above the filter stones, so as to cover the civil air defense opening through the protective cover. The filter stones and fine sand are used to fully filter the sewage. The filter stones and fine sand can also be replaced by other multi-layer filter meshes that can filter the sewage.

[0009] Preferably, a sewage cleaning port communicated with the liquid inlet chamber is arranged at the lower side of the filter tank. A rib plate is connected to the bottom of the filter tank. The liquid inlet chamber is located between the support net and the rib plate, and the horizontal plane of the rib plate is inclined towards the side of the mixing chamber. The inclined arrangement of the rib plate enables the sewage inside the liquid inlet chamber to be automatically introduced into the mixing chamber, and the sewage cleaning port is used to introduce clean water to clean the liquid inlet chamber and the connected mixing chamber.

[0010] Preferably, a discharge pool is provided on the side of the medicine cylinder away from the filter pool. The discharge pool is communicated with the mixing chamber, and flow guiding plates are arranged in the discharge pool in a staggered manner. A discharge pipe is communicated with the lower side of the discharge pool, and a drain pipe is communicated with the upper side of the discharge pipe. Thus, the sewage after the liquid medicine mixing treatment can be introduced into the discharge pool, and the temporary storage time of the sewage and the liquid medicine mixing reaction is increased through the flow guiding plates in the discharge pool, improving the sufficiency of the mixing reaction of the sewage treated by the liquid medicine. At the same time, the treated sewage is discharged through the drain pipe, and the different height differences between the drain pipe and the discharge pipe are used to improve the temporary storage effect of the sewage in the discharge pool. A part of the flow guiding plate is connected to the top surface of the discharge pool and a gap is reserved between the flow guiding plate and the bottom surface of the discharge pool. Another part of the flow guiding plate is connected to the bottom surface of the discharge pool and a gap is reserved between the flow guiding plate and the top surface of the discharge pool, so that the sewage flows sequentially along the gap between the flow guiding plate and the discharge pool after entering the discharge pool.

[0011] Preferably, columns connected to the medicine cylinder are provided between the mixing chamber and the liquid inlet chamber and between the mixing chamber and the discharge pool. The end of the discharge pipe is detachably connected with a valve cover, and a cover plate is hinged above the feeding port. The medicine cylinder can be lifted and supported through the arrangement of the columns, facilitating the sewage to enter the mixing chamber through the liquid inlet chamber for reaction and then be introduced into the discharge pool, so as to improve the connectivity between the mixing chamber, the liquid inlet chamber and the discharge pool. The feeding port is provided to facilitate the operator to input different sewage treatment medicines according to the sewage content, and the safety of the feeding port is increased through the cooperatively connected cover plate thereon. After the valve cover at the end of the discharge pipe is opened, the sewage can be directly discharged through the discharge pipe, improving the cleaning effect inside the discharge pool.

[0012] The beneficial effects of the present utility model are as follows: Since the outer surface of the rotating shaft is connected with stirring blades and spiral blades, and a feeding port and a feeding cylinder are communicated above the medicine cylinder, it is also convenient to separately introduce medicines or liquid medicines through the feeding port and the feeding cylinder, and the medicines can be completely mixed and stirred by the stirring blades and the spiral blades. The spiral blades convey and lift the medicines, and are mixed and stirred by the stirring blades. At the same time, the baffle on the inner surface of the medicine cylinder blocks and disturbs the mixing of the medicines, improving the stirring efficiency and mixing effect of the medicines. The mixing cavity below the medicine cylinder is communicated with the liquid inlet cavity below the filter tank, so that the mixed medicines can be directly introduced into the mixing cavity through the medicine outlet pipe and come into contact and mix with the sewage flowing into the liquid inlet cavity. The mixing effect of the sewage and the liquid medicine is improved by the impeller connected to the lower end of the rotating shaft and located inside the mixing cavity, so that the sewage and the liquid medicine can fully contact, react and mix with each other. The sewage flows into the mixing cavity through the liquid inlet cavity to obtain automatic liquid medicine mixing treatment, and automatically flows into the discharge pool after mixing, effectively improving the mixing effect of the sewage and the medicine, and also improving the convenience of liquid medicine feeding for sewage treatment. At the same time, when the sewage is inside the filter tank, it is first preliminarily filtered through the filter element and the support net, effectively avoiding the reduction of the mixing effect of the sewage and the liquid medicine due to the mixing of impurities in the sewage, ensuring the full contact and reaction of the liquid medicine and the sewage, and improving the medicine treatment effect of the sewage.
