Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection, and in particular to a material level gauge electrode protection mechanism and a dust removal ash material level detection device. Background Technology
[0002] In ultra-low dust removal systems in industries such as chemical engineering, environmental protection, and water treatment, admittance level switches are frequently used to detect the material level in ash silos.
[0003] Because of the unique characteristics of dust collector dust (it is typically corrosive, highly adhesive, and has small particles), its detection is challenging. Currently, radar waves, ultrasonic waves, and rotary paddle switches are commonly used for detection. While radar waves can be installed in warehousing systems, they are often affected by dust dispersion, making installation difficult in bucket storage systems. Therefore, admittance level switches and rotary paddle level switches are commonly used for level detection in bucket storage systems. Rotary paddle level switches are a mechanical detection method that is stable and effective, but has a relatively short lifespan.
[0004] In practical applications, admittance level switches and tuning fork level switches are commonly used to detect material levels. Both admittance level switches and tuning fork level switches are electronic detection devices, which are efficient and easy to install. However, they often cause false detections due to dust adhering to the electrodes and not being cleaned in time, requiring frequent cleaning and resulting in a large workload for maintenance. To address these issues, a new design has been made for the installation and sampling device of the level gauge, which can conveniently and promptly clean the dust adhering to the electrodes, or automatically perform timed cleaning to ensure the continuity of production. Utility Model Content
[0005] This utility model provides a level gauge electrode protection mechanism and a dust removal ash level detection device that can reduce dust accumulation on the level gauge electrode and enable timely cleaning.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A level gauge electrode protection mechanism includes a mounting sleeve, a protective layer, and a purge port. The mounting sleeve is used to install the level gauge electrode, the protective layer is installed above the level gauge electrode to reduce dust falling from above, and the purge port is installed on the mounting sleeve for connecting compressed air to purge the level gauge electrode.
[0008] Preferably, the protective layer is made of angle steel or sheet metal folded into a roof shape.
[0009] Preferably, the compressed air connected to the purging port is purged periodically by a solenoid valve.
[0010] Preferably, the electrode of the level gauge is the electrode of an admittance level switch or a tuning fork level switch.
[0011] Preferably, it is used in a dust removal ash level detection device.
[0012] A dust removal ash level detection device includes a storage mechanism and a dust removal ash level detection device installed on the storage mechanism for detecting the dust removal ash level, wherein the dust removal ash level detection device is the dust removal ash level detection device as described above.
[0013] Preferably, there are multiple dust removal ash level detection devices, which are installed at different heights in the storage mechanism.
[0014] The beneficial effects of this utility model are: the electrode protection mechanism of the level gauge and the dust removal ash level detection device of this utility model have a protective layer above the level gauge electrode to reduce the amount of ash falling on the electrode and avoid false alarms caused by ash accumulation; a blowing interface is added to the mounting sleeve to connect compressed air, so as to blow away the ash accumulated on the electrode in time and eliminate false alarms caused by ash accumulation. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the dust removal ash level detection device according to an embodiment of the present invention. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and examples.
[0017] In this embodiment, as Figure 1 As shown, the dust removal ash level detection device includes a storage mechanism (such as a silo, tank, or hopper) and a dust removal ash level detection device installed on the storage mechanism for detecting the dust removal ash level. There can be multiple dust removal ash level detection devices (two in this embodiment), each installed at different heights within the storage mechanism.
[0018] The level gauge electrode protection mechanism includes a mounting sleeve 1, a protective layer 2, and a purge interface 3. The mounting sleeve 1 is used to mount the level gauge electrode 4. The protective layer 2 is installed above the level gauge electrode 4 to reduce dust falling from above. The purge interface 3 is installed on the mounting sleeve 1 and is used to connect compressed air to purge the level gauge electrode 4. It can be used in conjunction with a solenoid valve for timed automatic purging.
[0019] In this embodiment, the mounting sleeve 1 can be connected by thread or flange (flange 5 is used in this embodiment). The protective layer 2 is made of angle steel or plate and is roof-shaped. The compressed air connected to the purging port 3 is controlled by a solenoid valve and incorporated into the automatic control of the host computer for timed purging. Of course, a manual valve can also be used for manual timed purging. The level gauge electrode 4 is the electrode of an admittance level switch or a tuning fork level switch, or it can be the electrode of other level detection elements.
[0020] In this embodiment, the electrode protection mechanism of the level gauge is used in the dust removal ash level detection device. Of course, it can also be applied to other devices in other embodiments.
[0021] This embodiment can accurately reflect the true material level value of the tested silo, tank, and hopper during the detection process, while protecting the electrodes from damage, extending their service life, and playing a beneficial role in the continuity of production.
