Description

Technical Field

[0002] A kiln head dust collector is a dust removal device used in the kiln head section of an industrial kiln. Currently, kiln head dust collectors have some drawbacks. First, they are insufficient in terms of energy saving, as most lack dedicated energy-saving structures. Because they primarily rely on adjusting the opening degree of baffles or valves to regulate parameters such as gas flow, pressure, and temperature, this adjustment method is relatively crude. This drawback arises because this adjustment method has relatively low technical content, simply changing the size of the gas passage to control flow, etc. During the adjustment process, it is difficult to accurately match the actual operating conditions of the kiln, easily leading to energy waste.

[0003] The conventional approach is to increase the frequency of manual monitoring and adjustment, but this relies on the experience and responsibility of the operators. The drawback is that manual monitoring has time intervals, preventing real-time and precise adjustments. Furthermore, manual operation is prone to errors, and over-reliance on manpower increases labor costs. In cases of human negligence, equipment operating efficiency may decrease, gas conditions may not be effectively controlled, and dust removal and energy utilization efficiency may be affected. Therefore, a new structure is needed to address these technical problems. Utility Model Content

The front side surface and the rear side surface of the fan box 200 are respectively provided with the air duct one 210 and the air duct two 220. The upper side surface of the fan box 200 is provided with a fan one 240 through a mounting piece 230. The dust removal assembly comprises: a fixed frame 300 and a dust collector body 330. The fixed frame 300 is internally provided with the dust collector body 330. The upper side surface of the dust collector body 330 is provided with a fan two 340. The outer side surface of the dust collector body 330 is provided with an air inlet pipe 310 and an air outlet pipe 320. The lower side surface of the dust collector body 330 is provided with a discharge port 350. The air inlet pipe 310 is connected with the air duct two 220. The fan one 240 and the fan two 340 are electrically connected with the fan frequency converter 100 through a cable 110.

[0022] Please refer to Figs. 1 to 3 As a first embodiment of the present application: the air duct one 210 and the air duct two 220 are of the same structure. The diameters of the air duct one 210 and the air duct two 220 are greater than that of the fan box 200. The diameter of the air duct two 220 is greater than that of the air inlet pipe 310. The end of the air duct one 210 away from the fan box 200 is connected with the kiln head.

When the gas enters the fan box 200, the user can start the fan 1 240 on the upper surface of the fan box 200 to increase the air inlet speed of the gas. Since the diameter of the fan box 200 is greater than the diameter of the air duct 2 220 and the air duct 1 210, the pressure and speed of the gas entering and discharging are increased. Since the air duct assembly composed of the air duct 1 210, the fan box 200 and the air duct 2 220 provides an orderly flow channel for the dust-containing gas during use, this design can preliminarily guide and arrange the gas before entering the fan, and reduce the degree of turbulence of the airflow.

[0027] The fan frequency converter 100 is internally provided with a frequency conversion module and an inverter module, and the frequency conversion module and the inverter module are electrically connected to the fan 1 240 and the fan 2 340 through the cable 110;

[0028] In use, when the gas enters into the air inlet pipe 310, at this time the user can open the dust remover body 330 and the fan two 340 on the upper surface of the dust remover body 330, at this time the gas enters into the dust remover body 330 for dust removal (the dust remover body 330 is a cyclone dust collector, and the specific structure, dust removal effect and dust removal steps are prior art, which will not be repeated here), after the dust removal of the dust remover body 330 is completed, the gas is discharged through the gas outlet pipe, and then the dust and impurities in the gas are discharged through the discharge port 350 on the lower surface of the dust remover body 330, when the fan one 240 and the fan two 340 are used, the user can adjust the rotating speed of the fan one 240 and the fan two 340 through the fan frequency converter 100 matched with the inverter module and the frequency conversion module (the type of the inverter module, the frequency conversion module, the fan one 240 and the fan two 340 can be selected from the existing market type, and the specific working principle and structure will not be repeated here), because in use, in the kiln head production process, the generation amount of waste gas is not constant, for example, in the kiln production adjustment, kiln start and stop stage, the waste gas amount will change, the frequency control (fan frequency converter 100) control device can accurately control the air volume by adjusting the rotating speed of the fan one 240 and the fan two 340 according to the actual waste gas generation amount, when the waste gas amount decreases, the rotating speed of the fan is reduced, and the energy consumption of the fan is proportional to the cube of the rotating speed, for example, if the rotating speed of the fan is reduced to 80% of the original, then the energy consumption of the fan will be reduced to about 51.2% (0.83) of the original, so that the energy saving effect is achieved;

[0029] At the same time, the energy saving rate of the fan at different frequencies is different, according to the principle of fluid mechanics, the air volume of the fan is proportional to the rotating speed of the motor, the air pressure of the fan is proportional to the square of the rotating speed of the motor, the shaft power of the fan is equal to the product of the air volume and the air pressure, so the shaft power of the fan is proportional to the square of the rotating speed of the motor (that is, the shaft power of the fan is proportional to the square of the power supply frequency), and it can be known from the above that the rotating speed frequency control can achieve the purpose of energy saving.

[0030] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
