Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and energy saving, and in particular to an energy-saving intelligent dust removal device. Background Art

[0002] Intelligent dust removal equipment is a kind of equipment that can effectively remove pollutants from the air. In the field of automobile production, intelligent dust removal equipment is mainly used for dust removal in the welding process on automobile production lines. A large amount of welding smoke and harmful gases will be generated during the automobile welding process. If they are not effectively treated, it will not only harm the health of workers, but also pollute the environment. Intelligent dust removal equipment can effectively capture and filter the smoke and particulate matter generated during the welding process to ensure the cleanliness of indoor air.

[0003] In the prior art, dust removal equipment generally uses a fan and a dust removal station together. The fan draws the generated smoke and harmful gases into the system to capture the smoke and harmful gases at different welding sites. The captured smoke and harmful gases will be processed by the dust removal station. After filtering and purification, the clean air will be released into the atmosphere, and solid particulate matter will be collected at the same time. However, in the above operation, if each single-station equipment is not in production, the personnel cannot close the manual air valve in time, and unmanned welding sites will occupy the air volume of the fan, resulting in a waste of air volume and increasing the energy consumption of the dust removal equipment. Utility Model Content

[0004] In order to solve the above technical problems, the utility model uses the main controller to compare the detected wind pressure signal of the main pipeline with the preset pressure range, and adjusts the frequency of the wind source according to the wind pressure signal. The specific technical solution is as follows:

[0005] An energy-saving intelligent dust removal device includes a dust removal detection component, which includes a dust removal device and a main controller installed on the side wall of the dust removal device; a wind source component, which is connected to the main controller through a wire; and a connecting component, which includes a main pipeline connecting the wind source component with the dust removal device and connecting the dust removal device to a welding station, the inner wall of the main pipeline is installed with a wind pressure detection component that sends a wind pressure signal to the main controller, and the main controller converts the wind pressure signal into a corresponding output frequency of the wind source component.

[0006] Preferably, the dust removal detection member further comprises a water pump connected to the dust removal device through a pipe.

[0007] Preferably, at least one of the wind pressure detection components is installed on the inner wall of the main duct on different sides of the dust removal detection component.

[0008] Preferably, the wind source component includes a fan connected to the dust removal equipment through a main duct.

[0009] Preferably, the welding station comprises a welding platform, welding parts arranged in the welding platform, and a sub-controller installed on a side wall of the welding platform.

[0010] Preferably, the connecting piece further comprises a branch pipe communicated with the main pipe, and the branch pipe is provided with a wind valve and a fire damper connected to the wires of the sub-controller.

[0011] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0012] The main controller is set to receive the signal of the wind pressure detection component, and the main controller is used to compare the detected wind pressure signal of the main pipeline with the preset pressure range. When the wind pressure in the main pipeline is greater than the corresponding preset value, and combined with the sub-controller to start and stop the air valve, the main controller will reduce the frequency of the wind source component to save air volume; when the main pipeline pressure is lower than the preset value, the main controller increases the working frequency of the fan to ensure the dust removal effect of the corresponding welding station.

[0013] One or more wind pressure detection devices are installed on the main ducts on both sides of the dust removal equipment. The main controller can effectively reduce the measurement error by measuring and comparing the data of multiple wind pressure detection devices. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0020] like Figure 1-Figure 3 As shown, an energy-saving intelligent dust removal device includes a dust removal detection component 20, which includes a dust removal device 201 and a main controller 203 installed on the side wall of the dust removal device 201; a wind source component 10, which is connected to the main controller 203 through a wire; and a connecting component 30, which includes a main pipeline 301 that connects the wind source component 10 with the dust removal device 201 and connects the dust removal device 201 to the welding station 40, and the inner wall of the main pipeline 301 is installed with a wind pressure detection component 302 that sends a wind pressure signal to the main controller 203, and the main controller 203 converts the wind pressure signal into a corresponding output frequency of the wind source component 10, wherein the wind source component 10 generates air volume, which passes through the main pipeline 301 exhausts air from each welding station 40, and the smoke gas passes through the main pipeline 301 and the dust removal equipment 201. The dust removal equipment 201 is used to filter and clean the smoke in the gas to ensure the cleanliness of the air, such as using a filter element or a filter bag to filter the smoke in the air. Finally, the cleaned gas is discharged from the wind source component 10 to achieve the dust removal effect for each welding station 40; as the wind source component 10 works, the wind pressure detection component 302 detects the wind pressure in the main pipeline 301, and sends the wind pressure detection signal to the main controller 203 for processing. After processing, the main controller 203 compares it according to the preset threshold value, and the main controller 203 outputs the corresponding frequency to the wind source component 10 according to the comparison result.

[0021] Specifically, if the main controller 203 determines through the wind pressure detection component 302 that the wind pressure in the main pipeline 301 is greater than the corresponding preset value, the main controller 203 determines that at least one welding station 40 has stopped working, and the main controller 203 will reduce the frequency of the wind source component 10 to save air volume. Otherwise, the frequency of the wind source component 10 will be increased to ensure the dust removal effect of each welding station 40.

[0022] The wind pressure detection element 302 can be of multiple types, such as one or more combinations of pressure sensors, wind speed sensors, wind direction sensors and piezoelectric sensors, wherein the pressure sensor can measure the pressure of gas or liquid, and determine the wind pressure by measuring the change in wind pressure; the wind speed sensor can measure the speed of the wind, and the wind pressure can be calculated by combining the area of ​​the wind; the wind direction sensor can measure the direction of the wind, and the wind pressure can be calculated by combining the wind speed and area; the piezoelectric sensor can convert the change in wind pressure into an electrical signal, and determine the wind pressure by measuring the change in the electrical signal.

[0023] like Figure 1 and Figure 2 As shown, the dust removal detection component 20 also includes a water pump 202 connected to the dust removal equipment 201 through a pipe. The water pump 202 provides sufficient water source for the dust removal equipment 201, uses water mist or water curtain to capture and clean smoke and exhaust gas, effectively prevents sparks from flying, and reduces the risk of fire.

[0024] At least one wind pressure detection component 302 is installed on the inner wall of the main duct 301 on different sides of the dust removal detection component 20. Regarding the installation of the above-mentioned wind pressure detection component 302, one or more wind pressure detection components 302 can be installed on the main duct 301 on both sides of the dust removal equipment 201 as needed. The main controller 203 can effectively reduce the measurement error by measuring and comparing the data of multiple wind pressure detection components 302.

[0025] like Figure 1 and Figure 4 As shown, the wind source component 10 includes a fan 102 connected to the dust removal equipment 201 through the main pipeline 301; the wind source component 10 also includes a mounting frame 101 installed on the outside of the fan 102 and an air outlet pipe 103 connected to the air outlet of the fan 102 and fixed to the mounting frame 101; wherein, the mounting frame 101 is used to fix the fan 102, and the air outlet pipe 103 is used to adjust the exhaust direction of the fan 102.

[0026] like Figure 1 and Figure 3 As shown, the welding station 40 includes a welding platform 401, a welding part 402 arranged in the welding platform 401, and a sub-controller 403 installed on the side wall of the welding platform 401. The connecting part 30 also includes a sub-pipeline 303 connected to the main pipeline 301. The sub-pipeline 303 is provided with a wind valve 305 and a fire damper 304 connected to the sub-controller 403 by wires. The welding part 402 includes but is not limited to a clamp, a welding head and a robot. For welding of workpieces, the sub-controller 403 is used to monitor and start and stop the fire damper 304 and the wind valve 305 in addition to controlling and monitoring the welding part 402.

[0027] When used specifically, the steps are as follows:

[0028] ① The air valve 305 of each welding station 401 is associated with the power signal. When the welding station 401 robot moves, the welding station 401 automatically opens the air valve 305 of the current welding station 401 according to the sub-controller 403.

[0029] ② For the wind pressure detection member 302 of the main pipeline 301 , the main controller 203 presets a pressure value to meet the normal working requirements of the fan 102 .

[0030] ③ When the pressure of the main pipeline 301 is lower than the preset value, the main controller 203 increases the operating frequency of the fan 102. After the pressure of the main pipeline 301 reaches the preset value, it starts to stabilize within the range, and the pressure value fed back by the wind pressure detection element 302 is always kept at the preset pressure value.

[0031] ④ When the robot at the welding station 401 does not move for several minutes, the sub-controller 403 automatically closes the air valve 305, the pressure of the main pipeline 301 will rise, and the signal will be fed back to the main controller 203. The main controller 203 gradually reduces the frequency of the fan 102 to achieve energy saving effect.

[0032] The fire damper 304 can detect whether a fire occurs at the corresponding welding station 401. If a fire occurs at a single welding station 401, the sub-controller 403 receives a signal from the fire damper 304 and closes the fire damper 304, so that the sub-pipe 303 corresponding to the welding station 401 is closed, and the fire damper 304 corresponding to the welding station 401 sends a signal to the main controller 203, and the main controller 203 turns off the fan 102. The main controller 203 can issue an alarm to notify the staff to handle it.

[0033] The main controller 203 and sub-controller 403 mentioned above are preferably Siemens 1200 series PLC, and the main controller 203 can be equipped with an additional frequency converter to adjust the frequency of the fan 102. The frequency converter can be ACS-510-75 produced by ABB.

[0034] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
