Description

An automatic energy-saving control system for a dust collector

【Technical field】

The utility model relates to the technical field of industrial machinery and equipment, in particular to an automatic energy-saving control system for dust collectors.

【Background technique】

The dust collector is one of the equipments for purifying the dusty gas. Its function is to intercept the dust in the dusty gas before it is discharged, and discharge the purified gas into the atmosphere. In the existing industrial dust collector, when opening or closing several air outlets, the power of the air motor cannot be automatically changed according to the number of actual air outlets. Waste is not conducive to realizing the concept of energy saving and environmental protection.

【Content of invention】

The purpose of the utility model is to overcome the shortcomings of the prior art and provide an automatic energy-saving control system for dust collectors with reasonable structure, high degree of automation, energy saving and environmental protection.

In order to solve the problems of the technologies described above, the utility model adopts the following technical solutions:

An automatic energy-saving control system for a dust remover, including a power processor, a pressure sensor, a controller, a converter, a frequency converter, a dust remover with multiple air outlets, and a man-machine dialogue machine that can set parameters. There are one or more exhaust motors in the device, and the power processor provides power for the entire system. The pressure sensor is connected to the controller and the detected signal is fed back to the controller. The controller receives the signal from the pressure sensor and controls the exhaust. The operating frequency of the motor, a converter and a frequency converter are sequentially connected between the controller and the exhaust motor, and the man-machine dialogue is connected to the controller.

Preferably, the pressure sensor is arranged at the air inlet of the fan motor.

Preferably, the controller is a PLC controller.

Compared with the prior art, in the automatic energy-saving control system for the dust remover described in the utility model, when closing or opening several air outlets, the pressure in the air duct changes, the pressure sensor sends a signal to the controller, and the controller adjusts The working power of the exhaust motor realizes the purpose of automatic energy saving.

【Description of drawings】

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model embodiment;

In the figure, 1-power processor, 2-pressure sensor, 3-controller, 4-converter, 5-inverter, 6-exhaust motor, 7-man-machine dialogue.

[Specific examples]

As shown in Figure 1, an automatic energy-saving control system for a dust collector includes a power processor 1, a pressure sensor 2, a controller 3, a converter 4, a frequency converter 5, a dust removal device with multiple air outlets, and a A human-machine dialogue machine 7 for setting parameters, one or more exhaust motors 6 are arranged in the dust removal device, the power processor 1 provides power for the whole system, the pressure sensor 2 is connected to the controller 3 and the detected signal Feedback to the controller 3, the controller 3 receives the signal of the pressure sensor 2 and controls the working frequency of the fan motor 6, the converter 4 and the frequency converter 5 are connected in sequence between the controller 3 and the fan motor 6, man-machine dialogue The machine 7 is connected to the controller 3.

In the present embodiment, the pressure sensor 2 is arranged at the air inlet of the exhaust motor 6, and the controller 3 is a PLC controller.

Using the automatic energy-saving control system for the dust remover described in the utility model, when the pressure in the exhaust pipe changes due to closing or opening several air outlets, the pressure sensor 2 sends a signal to the controller 3, and the controller 3 adjusts the work of the exhaust motor 6 Power, to achieve the purpose of automatic energy saving.

For example, on the operation interface of the man-machine dialogue machine 7, the pressure of a single air exhaust port is set to be 2KPa, and the air exhaust motor 6 is provided with ten air exhaust ports. The total pressure of the air exhaust motor 6 is a stable value. The area of the air outlet becomes smaller, the pressure in the air duct increases, the signal detected by the pressure sensor 2 is fed back to the controller 3, and the controller 3 reduces the operating frequency of the air motor 6 after receiving the signal from the pressure sensor 2, and the air is exhausted during operation. The motor 6 does not need to run at full load throughout the whole process, and the operating frequency of the exhaust motor 6 is automatically adjusted according to the actual situation to save electric energy, which is conducive to realizing the concept of energy saving and environmental protection.

The utility model has the advantages of reasonable structure, high degree of automation, energy saving and environmental protection, and is suitable for wide popularization.

Although the present utility model has been described in detail with reference to the above embodiments, it is apparent to those skilled in the art through this disclosure that the present utility model can be modified without departing from the principle and spirit scope of the present utility model defined by the claims. New models make various changes or modifications. Therefore, the detailed description of the embodiments of the present disclosure is only for explaining, not for limiting the utility model, but the scope of protection is defined by the content of the claims.
