Description

Technical Field

[0001] The invention relates to the technical field of fire safety of drying towers, in particular to monitoring equipment for fire safety of pressure spray drying towers. Background Art

[0002] With the continuous development of industry, pressure spray drying towers have been widely used in many fields. However, there are certain fire safety hazards in the operation of pressure spray drying towers.

[0003] On the one hand, traditional pressure spray drying tower monitoring equipment often suffers from a limited monitoring angle. It is usually fixed at a single location, making it difficult to achieve comprehensive observation and prone to blind spots. This means that abnormalities in key locations may not be discovered in time, delaying the response.

[0004] Furthermore, because pressure spray drying towers typically operate in harsh environments, impurities such as dust and moisture can easily adhere to monitoring equipment, blurring the images and affecting monitoring effectiveness. Existing monitoring equipment often lacks effective self-cleaning features, requiring regular manual cleaning and maintenance. This not only increases labor costs but can also impact normal operation due to untimely cleaning.

[0005] To this end, we propose a monitoring device for fire safety of pressure spray drying tower to solve the above problems. Summary of the Invention

The rotating connecting frame is provided with an engaging hole and a gear cavity. The output end of the gear transmission mechanism extends into the gear cavity and is installed with a synchronous belt transmission mechanism. The output end of the synchronous belt transmission mechanism passes through the rotating connecting frame and is installed with a rotating frame. The rotating frame is sleeved on the outer surface of the monitor. Cleaning brushes are evenly installed on the rotating frame, and the cleaning brushes are against the outer surface of the monitor.

[0013] In the above-mentioned monitoring equipment for fire safety of a pressure spray drying tower, two embedded seats are symmetrically installed on both sides of the mounting portion, and each L-shaped clamping frame is located at the lower end surface of the embedded seat at the corresponding position.

DETAILED DESCRIPTION

[0022] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Example Reference Figure 1-7A monitoring device for fire safety of a pressure spray drying tower includes a pre-buried base 19 and a mounting base 1, and the mounting base 1 is installed on the pre-buried base 19 by a plurality of locking screws 21. The pre-buried base 19 includes a mounting portion 1901, and two L-shaped clamping frames 1903 are symmetrically installed at both ends of the mounting portion 1901. A fixing plate 22 is installed on the mounting base 1, and the fixing plate 22 is clamped between the two L-shaped clamping frames 1903. The upper end surface of the fixing plate 22 contacts the lower end surface of the mounting portion 1901. A plurality of mounting holes 23 are symmetrically opened on the fixing plate 22, and each locking screw 21 is located at The mounting portion 1901 is installed in the corresponding mounting hole 23 and on the corresponding L-shaped clamping frame 1903. Two embedded seats 1902 are symmetrically installed on both sides of the mounting portion 1901, and each L-shaped clamping frame 1903 is located at the lower end surface of the corresponding embedded seat 1902. The lower end surface of each embedded seat 1902 is an inclined surface, and the angle between the lower end surface of the embedded seat 1902 and the vertical surface of the L-shaped clamping frame 1903 is 80°-70°. This inclined surface design can enable the embedded seat to have a larger contact area with the surrounding soil or foundation material and support force in different directions after being buried underground. When the equipment is subjected to forces from different directions, the embedded seat can better disperse the force to the surrounding soil, thereby improving the stability of the entire device. For lateral forces that may exist around the pressure spray drying tower, such as wind force and vibration during equipment operation, the inclined surface design can provide a certain lateral resistance, reducing the displacement risk of the embedded seat and the entire device. The inclined surface at a specific angle can change the stress distribution of the embedded seat when subjected to force, so that the stress is more evenly distributed in various parts of the embedded seat, reducing local stress concentration, thereby improving the structural strength and service life of the embedded seat. A positioning frame 20 is installed on the mounting portion 1901, and the positioning frame 20 is located between the mounting portion 1901 and the L-shaped clamping frame 1903, and the positioning frame 20 is against the outer wall of the fixed plate 22.

[0024] The mounting base 1 is provided with a mounting cavity 2, in which a driving motor 3 is installed. The output shaft of the driving motor 3 passes through the mounting base 1 and is provided with a rotating connecting frame 4, to which a monitor 5 is fixedly connected. A gear transmission mechanism is installed between the mounting seat 1 and the rotating connecting frame 4. The rotating connecting frame 4 is provided with an engagement hole 7 and a gear cavity 8. The gear transmission mechanism includes an incomplete bevel gear ring 6, and the incomplete bevel gear ring 6 is fixedly installed on the lower end surface of the mounting seat 1. A first mounting shaft 9 is installed in the gear cavity 8. One end of the first mounting shaft 9 extends into the engagement hole 7 and is installed with a bevel gear 11, and the bevel gear 11 is engaged with the incomplete bevel gear ring 6.

[0025] The output end of the gear transmission mechanism extends into the gear cavity 8 and is installed with a synchronous belt transmission mechanism. The output end of the synchronous belt transmission mechanism passes through the rotating connecting frame 4 and is installed with a rotating frame 15. The synchronous belt transmission mechanism includes a second mounting shaft 10, and the second mounting shaft 10 is installed in the gear cavity 8, and the rotating frame 15 is installed on the second mounting shaft 10. The first mounting shaft 9 and the second mounting shaft 10 are respectively installed with the first synchronous wheel 12 and the second synchronous wheel 13, and the first synchronous wheel 12 and the second synchronous wheel 13 are both located in the gear cavity 8. A synchronous belt 14 is jointly installed on the first synchronous wheel 12 and the second synchronous wheel 13.

[0026] A notch is provided on the rotating frame 15, the size of which is larger than that of the rotating connecting frame 4. During the simultaneous rotation of the rotating frame 15 and the rotating connecting frame 4, the larger notch can ensure that there is no interference between the two. Even if a certain degree of offset or vibration occurs during the rotation process, the smoothness of the rotation can be guaranteed, avoiding the normal operation of the equipment being affected by collision between components.

[0027] The rotating frame 15 is sleeved on the outer surface of the monitor 5 . Cleaning brushes 16 are evenly mounted on the rotating frame 15 , and the cleaning brushes 16 abut against the outer surface of the monitor 5 .

[0028] A smoke sensor 17 and a temperature sensor 18 are installed on the rotating frame 15, and a controller and an alarm are installed in the monitor 5. The output ends of the smoke sensor 17 and the temperature sensor 18 are electrically connected to the input end of the controller, and the input end of the alarm is electrically connected to the output end of the controller.

[0029] During installation, the embedded base 19 is embedded in the installation position to provide a stable basic support for the entire device; the mounting base 1 is installed on the embedded base 19 by multiple locking screws 21, specifically, the fixed plate 22 slides between the two L-shaped clamping frames 1903 and the mounting portion 1901. When the side wall of the fixed plate 22 is against the positioning frame 20, it means that the fixed plate 22 is now in the installation position. At this time, the mounting hole 23 on the fixed plate corresponds to the position of the circular hole opened on the L-shaped clamping frame 1903. Then, the locking screws 21 are passed through the mounting hole 23 on the fixed plate 22 and installed on the L-shaped clamping frame 1903 to ensure the stability of the mounting base 1.

[0030] A drive motor 3 is installed in the mounting cavity 2 within the mounting base 1. When the drive motor 3 is in operation, its output shaft passes through the mounting base 1 and drives the rotating connecting frame 4 to rotate. As the rotating connecting frame 4 rotates, the bevel gear 11 in the gear cavity 8 (mounted on one end of the first mounting shaft 9 and extending into the meshing hole 7) engages with the partially beveled gear ring 6, causing the first mounting shaft 9 to rotate. This first mounting shaft 9 then drives the rotating frame 15 via a synchronous belt drive mechanism. The rotating frame 15, mounted on the second mounting shaft 10, is sleeved onto the outer surface of the monitor 5. A cleaning brush 16 on the rotating frame 15 continuously cleans the outer surface of the monitor 5 as the rotating frame 15 rotates, keeping it clean and ensuring a clear monitoring image. The rotating frame 15 is also equipped with a smoke sensor 17 and a temperature sensor 18. When the smoke concentration or temperature in the surrounding environment changes abnormally, the smoke sensor 17 and the temperature sensor 18 transmit signals to the controller within the monitor 5. The controller processes the signals and, if it detects an abnormality, activates an alarm to alert personnel to promptly address the fire safety issue.

[0031] It is worth noting that when the rotating frame 15 rotates, the smoke sensor 17 and the temperature sensor 18 are driven to move accordingly. The smoke sensor 17 and the temperature sensor 18 can detect at different angles and directions, avoid detection blind spots, and improve the comprehensiveness of monitoring the environment around the pressure spray drying tower. At the same time, by constantly changing positions, smoke and temperature data at more locations can be obtained. After comprehensive analysis, it can be more accurately determined whether there are fire safety hazards. If a fire hazard occurs, the abnormal situation can be detected more quickly during the rotation process, shortening the response time and gaining precious time for timely fire-fighting measures. For the influence of complex airflow or obstacles that may exist around the pressure spray drying tower, the rotation detection can better adapt to different environmental conditions and improve the reliability of detection.

[0032] This monitoring equipment realizes fire safety monitoring of the pressure spray drying tower through the coordinated work of various components. It also has self-cleaning and timely alarm functions, providing guarantees for the safe operation of the pressure spray drying tower.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
