Description

Technical Field

[0001] The present invention relates to the technical fields of detection and sewage discharge in boiler equipment, and in particular to an automatic sewage discharge mechanism for a boiler. Background Art

[0002] In the prior art, if the boiler boils water for too long, a lot of dirt will form inside the boiler over time. The method to remove this dirt is to add chemicals into the boiler and remove all the dirt on the boiler body through a series of chemical reactions.

[0003] For example, the patent document with publication (announcement) number: CN 215446416 U discloses "an automatic sewage discharge system for a steam boiler". In this technical solution, a transmission mechanism and an annular scraper structure are installed inside the boiler body. The annular scraper is used to scrape off scale on the inner wall of the boiler, thereby cleaning the boiler.

[0004] The above technical solution only uses a mechanical mechanism to remove the dirt on the inner wall of the boiler. The above technical solution cannot timely know the condition of the water inside the boiler, nor can it realize the automatic sewage discharge of the boiler, and cannot discharge the sewage inside the boiler in time.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a boiler automatic sewage discharge mechanism with reasonable structure and easy use. Summary of the Invention

[0006] The purpose of the present invention is to provide a boiler automatic blowdown mechanism to address the deficiencies in the prior art. The technical solution is as follows:

[0007] A boiler automatic sewage discharge mechanism comprises a boiler body, an inlet pipe is installed at the upper end of the boiler body, a funnel-shaped bottom is provided at the lower end of the boiler body, a water outlet pipe is installed at the lower end of the funnel-shaped bottom, and an electric control valve is installed on the water outlet pipe;

[0008] The slope of the funnel-shaped bottom is also equipped with evenly spaced support frames, which are fixedly supported by a detection chamber. The detection chamber is suspended and fixed in the boiler body. The detection chamber is located above the funnel-shaped bottom, and a plurality of internal detectors are horizontally installed in the detection chamber. External detectors corresponding to the positions of the internal detectors are provided on the side walls of the boiler body. The internal and external detectors are used in conjunction to detect data of the water body between the internal and external detectors.

[0009] The device also includes a controller, which is connected to the internal detector and the external detector and can correspondingly control the opening and closing of the electric control valve on the water outlet pipe.

[0010] Furthermore, a stirring motor is installed at the upper end of the boiler body. The main shaft of the stirring motor extends downward into the boiler body, and a plurality of stirring rods evenly spaced up and down are installed on the main shaft.

[0011] Furthermore, a sensor is installed on the side wall of the boiler body. The sensor is correspondingly installed between the upper and lower adjacent stirring rods, and the sensor is correspondingly connected to the controller.

[0012] Furthermore, the internal detector and the external detector are both configured as turbidity detectors; the principle of the turbidity detector is that the internal detector corresponds to the emission signal, while the external detector corresponds to the reception signal. If the water body is very turbid, the emitted signal will be refracted by the particles in the water body, and the amount of signal received by the external detector will be reduced, thereby judging the turbidity in the detection chamber, and the structure is reasonable.

[0013] Furthermore, the lower end of the main shaft of the stirring motor is installed on the upper end of the detection chamber through a bearing seat, and the main shaft and stirring rod above are correspondingly supported by the detection chamber.

[0014] Furthermore, the sensor is a probe-type sensor that can detect the temperature, pH value, dissolved oxygen content, hardness and total alkali content of the water in the boiler.

[0015] Furthermore, there are three internal detectors in the detection chamber that are evenly spaced, and there are three external detectors on the boiler body that are correspondingly evenly spaced.

[0016] Furthermore, the funnel-shaped bottom is provided with three corresponding support frames; the number and position of the support frames are reasonably set, so that the stirring mechanism can be supported and fixed more stably, and the structure is reasonable.

[0017] Beneficial effects: The present invention has the following beneficial effects:

[0018] 1) This device mainly sets up a suspended detection chamber inside the boiler, installs an internal detector in the detection chamber, and installs an external detector compatible with the internal detector on the side wall of the boiler body. The detection chamber is located inside the boiler body. When cleaning and draining, it is necessary to place the cleaning medicine into the boiler body. After the dirt on the side wall of the boiler body is cleaned, the internal water body will gradually become turbid. The internal and external detectors are set as turbidity detectors, which can judge the turbidity of the water body by the loss degree of the transmitted and received signals. When the water body is very turbid, the internal and external detectors can control the electric control valve to open through the controller accordingly, and the cleaned sewage is directly discharged to the outside, thereby realizing the automatic drainage function of the boiler cleaning;

[0019] 2) When the boiler body of the device is being cleaned, the cleaning efficiency, quality and effect can be improved by means of the stirring motor provided. The detection chamber of the device not only has the function of installing the internal detector, but also serves as a mounting seat for the main shaft of the stirring motor. The main shaft of the stirring motor is installed correspondingly through the bearing seat, which is more reasonable in structure and can improve the cleaning efficiency and quality.

[0020] 3) In this device, not only is a detection chamber set up inside the boiler body for detecting turbidity, but sensors are also installed to detect data such as temperature and pH value inside the boiler body. The structure is very reasonable, and the positions and numbers of sensors and detectors are set accordingly, making the measurement data more accurate and reliable, and convenient and safe to use.
