Description

Technical Field

[0001] This utility model relates to the field of energy-saving control technology, and in particular to an energy-saving control device for a circulating fan in a cement plant. Background Technology

[0002] A circulating fan is a device used for air circulation or airflow regulation. It is widely used in ventilation, air conditioning, heating and ventilation systems. Its main function is to push or draw in air or gas by rotating an impeller to achieve air flow and circulation.

[0003] Current fans cannot control the air intake volume according to actual needs, especially in cement plants. If the air volume cannot be controlled, if workers make a mistake while transporting cement powder and it falls to the ground, the excessive air volume will blow the cement powder everywhere, which will greatly increase the subsequent cleanup time.

[0004] To address the aforementioned issues, we propose an energy-saving control device for circulating fans in cement plants. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing an energy-saving control device for circulating fans in cement plants.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving control device for a circulating fan in a cement plant, comprising an air inlet pipe, an electric telescopic rod fixedly connected to the inner wall of the air inlet pipe, a track fixedly connected to the inner wall of the air inlet pipe, a sliding block slidably connected to the inner side of the track, a pushing frame provided inside the air inlet pipe, the outer wall of the pushing frame fixedly connected to the outer wall of the sliding block, the driving end of the electric telescopic rod fixedly connected to the outer wall of the pushing frame, a control frame fixedly connected to the inner wall of the air inlet pipe, a first blocking plate and a second blocking plate rotatably connected to the outer wall of the control frame, a plurality of springs fixedly connected to the outer wall of the control frame, the plurality of springs being respectively fixedly connected to the inner walls of the first blocking plate and the second blocking plate, the control frame having a plurality of through holes, and a plurality of push rods fixedly connected to the outer wall of the pushing frame.

[0007] In the above-mentioned energy-saving control device for a circulating fan in a cement plant, an installation frame is fixedly connected to the outer wall of the air inlet pipe, a fixing frame is provided on the outer wall of the installation frame, the fixing frame is connected to the installation frame by multiple installation screws, and a dust filter screen is provided inside the fixing frame.

[0008] In the above-mentioned energy-saving control device for a circulating fan in a cement plant, the first blocking plate is located above the second blocking plate, and the pushing frame is located to the left of the air control frame.

[0009] In the above-mentioned energy-saving control device for a cement plant circulating fan, a plurality of mounting screws are evenly arranged at the four corners of the fixed frame.

[0010] In the above-mentioned energy-saving control device for a circulating fan in a cement plant, a plurality of springs are evenly arranged on the outside of the air control frame, a plurality of perforations are evenly arranged at the four corners of the air control frame, and a plurality of push rods are evenly arranged at the four corners of the push frame.

[0011] In the aforementioned energy-saving control device for a cement plant circulating fan, the diameter of each of the push rods is smaller than the diameter of the perforation.

[0012] Compared with existing technologies, the advantages of this energy-saving control device for circulating fans in cement plants are as follows:

[0013] When the air intake volume is small, this utility model uses an electric telescopic rod to move the push frame to the right. The push frame moves horizontally to the right along the track due to the sliding block. When the push rod passes through the corresponding hole, it will contact the first and second blocking plates and cause the first and second blocking plates to rotate. This will increase the ventilation area of ​​the air control frame, thus increasing the air intake volume. Then, the electric telescopic rod can use the spring to drive the first and second blocking plates to rotate towards the air control frame, which will reduce the ventilation area and the air intake volume, thereby completing the air volume control.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3An energy-saving control device for a circulating fan in a cement plant includes an air inlet pipe 1. An electric telescopic rod 8 is fixedly connected to the inner wall of the air inlet pipe 1. A track 9 is fixedly connected to the inner wall of the air inlet pipe 1. A sliding block 10 is slidably connected to the inner side of the track 9. A pushing frame 14 is provided inside the air inlet pipe 1. The outer wall of the pushing frame 14 is fixedly connected to the outer wall of the sliding block 10. The driving end of the electric telescopic rod 8 is fixedly connected to the outer wall of the pushing frame 14. A wind control frame is fixedly connected to the inner wall of the air inlet pipe 1. 12. A first blocking plate 3 and a second blocking plate 4 are rotatably connected to the outer wall of the air control frame 12. Multiple springs 15 are fixedly connected to the outer wall of the air control frame 12. The multiple springs 15 are respectively fixedly connected to the inner side walls of the first blocking plate 3 and the second blocking plate 4. The air control frame 12 is provided with multiple through holes 13. Multiple push rods 11 are fixedly connected to the outer wall of the push frame 14. The first blocking plate 3 is located above the second blocking plate 4. The push frame 14 is located on the left side of the air control frame 12. The multiple springs 15 are evenly distributed on the air control frame 12. On the outside, multiple perforations 13 are evenly arranged at the four corners of the air control frame 12, and multiple push rods 11 are evenly arranged at the four corners of the sliding frame 14. The diameter of each push rod 11 is smaller than the diameter of the perforation 13. When the air intake is small, the electric telescopic rod 8 drives the sliding frame 14 to move to the right. The sliding frame 14 will move horizontally to the right along the track 9 due to the sliding block 10. When the push rod 11 passes through the corresponding perforation 13, it will contact the first blockage plate 3 and the second blockage plate 4, and drive the first blockage plate 3 and the second blockage plate 4 to move. When plate 24 rotates, the ventilation area of ​​the air control frame 12 is expanded, thus increasing the airflow. At this time, spring 15 will be stretched. When the airflow is felt to be too large, the electric telescopic rod 8 drives the push frame 14 to move to the left. This causes the push rod 11 to slowly disengage from the perforation 13. Spring 15 will then rotate the blocking plate 13 and blocking plate 24 towards the air control frame 12 through contraction force. This reduces the ventilation area and the airflow, thus completing the airflow control.

[0020] An installation frame 2 is fixedly connected to the outer wall of the air inlet duct 1. The outer wall of the installation frame 2 is provided with a fixing frame 5. The fixing frame 5 is connected to the installation frame 2 by multiple mounting screws 6. A dust filter 7 is provided inside the fixing frame 5. The multiple mounting screws 6 are evenly arranged at the four corners of the fixing frame 5. When the air inlet duct 1 receives airflow, some dirt and dust will be adsorbed into the air inlet duct 1. The dust filter 7 can effectively block most of the dirt and dust. After long-term use, the floating dust accumulated on the surface of the dust filter 7 can be removed by rotating and disassembling the mounting screws 6. In this way, the fixing frame 5 can be removed, the dust filter 7 can be cleaned, and it can be reinstalled for repeated use.

[0021] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
