Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to intelligent control of bulk clinker dust collection fans. Background Technology

[0002] Cement clinker is a semi-finished product in the cement production process. It is a gray-black granular substance obtained by calcining raw materials at high temperature in a kiln system and then cooling them. Its main chemical components include calcium oxide, silicon dioxide, aluminum oxide, and ferric oxide. A large amount of dust is generated during the bulk loading and transportation of cement clinker, so dust collection fans are needed to collect the dust.

[0003] The bulk production process is characterized by intermittent and irregular vehicle operations, with feeding stopping once the clinker silo is full. As a result, the feed conveyor belt is not continuously running, leading to prolonged ineffective operation of the dust collector fan. This does not align with the concept of green and environmentally friendly development. Furthermore, the dust collector fan operates at industrial frequency, causing the fan equipment to maintain a constant speed. The air pressure at the bulk head and steel silo feed inlet remains constant, resulting in rigid system control and a lack of flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide intelligent control for bulk clinker dust collection fans, which enables more flexible equipment control, real-time adjustment of the fan equipment according to working conditions, and is more environmentally friendly, with better energy-saving and emission-reduction effects.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The dust collector is connected to a connecting duct on the left side, and a fan assembly is connected to the left side of the connecting duct. A PLC control cabinet is installed on the left side of the fan assembly. An electric butterfly valve is installed and connected to the surface of the main duct. A side duct is welded and connected to the top right side of the main duct.

[0008] Preferably, the fan assembly includes a mounting base, and the variable frequency motor and the fan body are respectively bolted to the left and right sides of the top of the mounting base.

[0009] Preferably, a discharge valve is installed at the bottom of the dust collector, and a discharge pipe is connected to the bottom of the discharge valve. The bottom of the discharge pipe is fixedly connected to the main air duct.

[0010] Preferably, the bottom of the side air duct is fixedly connected to the electric valve, and the surface of the unloading pipe is equipped with an unloading valve.

[0011] Preferably, the output terminals of the PLC control cabinet are electrically connected to the fan assembly, the electric butterfly valve, and the electric valve, respectively, and the output terminal of the microwave flow switch is electrically connected to the PLC control cabinet.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The fan component control can change different operating modes according to four different working conditions, making the fan component more intelligent and versatile, and enabling it to operate in a targeted manner according to different working conditions, resulting in better energy saving and emission reduction effects.

[0014] 2. Through flexible control of electric butterfly valves and electric valves, non-dust-generating pipelines can be closed in a timely manner, and the fan assembly can concentrate airflow to collect dust from the material drop point, significantly improving the dust collection effect.

[0018] Please see Figures 1-2 The intelligent control of the bulk clinker dust collector includes a storage bin 1. The top left side of the storage bin 1 is connected to a feeding shell 3. The feeding shell 3 is used in conjunction with an external feeding belt. Since the feeding belt transports clinker into the feeding shell 3, a microwave flow switch 17 is installed through the bottom of the front side of the feeding shell 3.

[0019] An electric valve 16 is installed and connected to the top left side of the feeding shell 3. The bottom of the storage bin 1 is connected to the unloading pipe 4. The left side of the unloading pipe 4 is welded and connected to the main air pipe 5. The side of the main air pipe 5 away from the unloading pipe 4 is connected to the dust collector 13.

[0020] The dust collector 13 is connected to the left side of the connecting air duct 12, the connecting air duct 12 is connected to the left side of the fan assembly 18, the fan assembly 18 is provided with the left side of the PLC control cabinet 10, the surface of the main air duct 5 is installed and connected to the electric butterfly valve 15, and the top right side of the main air duct 5 is welded and connected to the side air duct 14.

[0021] Please see Figure 1 The fan assembly 18 includes a mounting base 9. The top left and right sides of the mounting base 9 are respectively connected to the variable frequency motor 11 and the fan body 8 by bolts. The transmission wheel at the output end of the variable frequency motor 11 is connected to the transmission wheel at the output end of the fan body 8 by a transmission belt.

[0022] Please see Figure 1 The bottom of the dust collector 13 is connected to a discharge valve 7. By setting the discharge valve 7, the opening and closing state of the discharge pipe 6 can be controlled. The bottom of the discharge valve 7 is connected to the discharge pipe 6. By setting the discharge pipe 6, the powdery clinker filtered in the dust collector 13 can be discharged through the main air pipe 5 and the unloading pipe 4 after the discharge valve 7 is opened. The bottom of the discharge pipe 6 is fixedly connected to the main air pipe 5.

[0023] Please see Figure 1 The bottom of the side air duct 14 is fixedly connected to the electric valve 16, and the surface of the unloading pipe 4 is connected to the unloading valve 2.

[0024] Please see Figure 1 and Figure 2 The output terminals of the PLC control cabinet 10 are electrically connected to the fan assembly 18, the electric butterfly valve 15 and the electric valve 16 respectively, and the output terminal of the microwave flow switch 17 is electrically connected to the PLC control cabinet 10.

[0025] When used, bulk clinker production conditions are as follows:

[0026] 1. When clinker enters storage silo 1 through feeding shell 3 and unloading valve 2 is closed and not loaded, microwave flow switch 17 detects that clinker flows into storage silo 1 through feeding shell 3 and transmits the signal to PLC control cabinet 10. At this time, PLC control cabinet 10 controls electric butterfly valve 15 to close, electric valve 16 to open, and sets the frequency of variable frequency motor 11 to 38HZ.

[0027] 2. When the feeding of clinker into storage bin 1 stops, microwave flow switch 17 detects that there is no clinker flow in feeding shell 3 and transmits the signal to PLC control cabinet 10. Then, unloading valve 2 is opened for loading. At this time, PLC control cabinet 10 controls electric butterfly valve 15 to open and electric valve 16 to close, and sets the frequency of variable frequency motor 11 to 45.8HZ.

[0028] 3. When the microwave flow switch 17 detects that the clinker in the feeding shell 3 is being conveyed into the storage hopper 1, and the unloading valve 2 opens to load the material, the PLC control cabinet 10 controls the electric butterfly valve 15 and the electric valve 16 to open, and sets the frequency of the variable frequency motor 11 to 50Hz for full-power operation.

[0029] 4. When the microwave flow switch 17 detects that there is no clinker being conveyed from the feeding shell 3 to the storage bin 1, and at the same time the unloading valve 2 of the loading vehicle is closed, the PLC control cabinet 10 controls the electric butterfly valve 15 and the electric valve 16 to close, and sets the frequency of the variable frequency motor 11 to 12.7HZ, and enters the sleep state.

[0030] Through the above measures, the operation mode of the fan assembly 18 is more intelligent and versatile, and it can operate in a targeted manner according to different working conditions, resulting in better energy saving and emission reduction. At the same time, due to the flexible control of the electric butterfly valve 15 and the electric valve 16, the non-dust-generating pipes are closed, and the fan assembly 18 can concentrate the air volume to collect dust from the material drop point, significantly improving the dust collection effect.

[0031] In summary, the intelligent control of this bulk clinker dust collector, through the coordinated use of the storage silo 1, unloading valve 2, feeding shell 3, main air duct 5, fan body 8, PLC control cabinet 10, variable frequency motor 11, dust collector 13, side air duct 14, electric butterfly valve 15, electric valve 16 and microwave flow switch 17, solves the problems of not conforming to the concept of green and environmentally friendly development, the inability of the fan equipment to adjust its power according to the working conditions, the rigid system control, and the unsatisfactory energy saving and emission reduction effect.
