Description

Technical Field

[0001] The utility model relates to the technical field of dosing equipment, in particular to a quantitative dosing equipment for cooling circulating water. Background Art

[0002] The water system is constantly recycled in the circulation system. Due to the combined effects of various factors such as the increase in water temperature, the change in water flow rate, water evaporation, the concentration of inorganic ions and organic matter, the dust and debris entering from the soft water tank, and the equipment structure and materials, there will be more serious sediment adhesion, equipment corrosion and large-scale breeding of microorganisms than the direct current system, as well as the resulting sludge and dirt blocking the pipeline. For the water quality stabilization treatment of the steam boiler inlet water, if the water quality is controlled by manual dosing, there are disadvantages such as large workload, inaccurate dosing control, and easy loss of control of water quality. In order to improve the internal cleaning efficiency of the cooling circulating water, a quantitative dosing device is needed, but the existing quantitative dosing device still has the following shortcomings:

[0003] For example, the utility model with application number 202122394462.4 discloses a fully automatic dosing device, which achieves the effect of scale removal and prevention by regularly adding corrosion inhibitors and scale inhibitors into the water supply pipeline. As the name suggests, corrosion inhibitors and scale inhibitors are water treatment agents that relieve corrosion and prevent scaling of equipment. They are mostly used in boilers and cooling circulating water equipment, so that their boiler feed water or circulating water is not easy to cause scaling and corrosion of equipment, extend their life, save costs and consumption. When the existing quantitative dosing equipment is used, since most quantitative dosing equipment does not have the function of monitoring the amount of medicine inside the dosing barrel, the demand for liquid medicine cannot be guaranteed, resulting in the problem of reduced practicality and reduced efficiency of quantitative dosing equipment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a quantitative dosing equipment for cooling circulating water is proposed. Utility Model Content

[0005] The utility model aims to provide a cooling circulating water quantitative dosing device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling circulating water quantitative dosing device, comprising a dosing barrel and a dosing component, a support frame is installed at the lower left end of the dosing barrel, a dosing component is arranged outside the dosing barrel, and the dosing component comprises a dosing pipe, a filter, a metering pump, a water supply valve, a liquid level sensor and a water inlet pipe, a filter is connected to the rear end of the dosing pipe, and a metering pump is connected to the front end of the dosing pipe, and a water supply valve is arranged at the front end of the metering pump, a liquid level sensor is arranged on the left side of the dosing barrel, and a water inlet pipe is connected to the upper left side of the dosing barrel, and a mixing component is arranged inside the dosing barrel.

[0007] Furthermore, an intelligent control panel is provided at the upper end of the support frame, and a circulating water pipe is distributed on the right side of the dosing barrel.

[0008] Furthermore, the dosing pipe is embeddedly connected to the dosing barrel, and the dosing pipe is threadedly connected to the filter.

[0009] Furthermore, the outer side of the metering pump is flush with the outer side of the medicine adding barrel, and the metering pump is threadedly connected to the medicine adding barrel.

[0010] Furthermore, the mixing assembly includes a servo motor, a rotating shaft, a support rod and a mixing rod. The front end of the servo motor is connected to the rotating shaft, the front end of the rotating shaft is connected to the support rod, and the front end of the support rod is additionally provided with a mixing rod.

[0011] Furthermore, the mixing assembly also includes a mounting block, a mixing cross bar and a liquid through hole. At the same time, a mounting block is arranged outside the support rod, a mixing cross bar is arranged outside the mounting block, and a liquid through hole is opened inside the mixing cross bar.

[0012] Furthermore, the mixing rod is in an "L" shape, and the mixing rod is symmetrically arranged on both sides of the bottom of the support rod.

[0013] Furthermore, the mixing cross bar and the support rod are distributed vertically, and the mixing cross bar is threadedly connected to the support rod through a mounting block.

[0014] The utility model provides a cooling circulating water quantitative dosing device, which has the following beneficial effects:

[0015] 1. The utility model can, through the arrangement of the dosing component, avoid the problem that most quantitative dosing devices do not have the function of monitoring the amount of medicine inside the dosing barrel when the quantitative dosing device for cooling circulating water is used by utilizing the dosing component arranged outside the dosing barrel, resulting in the problem that the demand for the amount of liquid medicine cannot be guaranteed, causing the problem of reduced practicality of the quantitative dosing device. The liquid level sensor installed on the left side of the dosing barrel monitors the capacity of the medicine inside the dosing barrel. When the capacity is reduced to a certain extent, the liquid level sensor operates and cooperates with the intelligent control panel to add medicine to the inside of the dosing barrel through the water inlet pipe, limits the dosing pipe inside the dosing barrel, and connects the front end of the dosing pipe with the metering pump. The metering pump operates in conjunction with the filter to transport the medicine to the inside of the circulating water pipe through the dosing pipe, so that the equipment can continuously, stably and quantitatively dosing the system. At the same time, the dosing operation is regulated by the water supply valve to improve the flexibility of the quantitative dosing equipment during use.

[0016] 2. The utility model can avoid the situation that most quantitative dosing equipment is difficult to fully mix the medicine when the quantitative dosing equipment for cooling circulating water is used through the setting of the mixing component inside the dosing barrel, so that the dosage of the medicine affects the treatment effect of the water quality, resulting in a decrease in the use efficiency of the quantitative dosing equipment. The servo motor is fixedly installed in the middle of the upper end of the dosing barrel through the fastening bolts, and the output shaft of the servo motor is connected to the rotating shaft through a coupling. The operation of the servo motor drives the rotating shaft to make the support rod connected to the front end of the rotating shaft rotate inside the dosing barrel, and then the mixing rod installed at the bottom of the support rod rotates inside the dosing barrel, so as to fully mix the medicine inside the dosing barrel and avoid the precipitation of the medicine. The mixing cross bar is fixedly installed on both sides of the outside of the support rod through the mounting block and the fastening bolts, and the centrifugal force in the process of mixing the medicine liquid is increased through the liquid through hole opened in the mixing cross bar, thereby increasing the mixing efficiency of the medicine, and further improving the convenience of the quantitative dosing equipment during use.
