Problems solved by technology

If the air pressure of back blowing is too low to blow off the dust on the filter element, it will have a series of adverse effects, 1. Waste of air source; 2. The service life of the filter element is greatly reduced; 3. The air flow speed at the dust collector is reduced , leading to a decrease in dust collection efficiency; 4. The air flow velocity in the dust collector is reduced, resulting in an increase in the dust concentration and temperature in the dust collector, which in turn reduces the operating safety of the dust collector

Embodiment 1

[0022] Such as figure 1 As shown, the dust collector includes a dust removal box 1 with a dust removal chamber and a fan 2 with a motor, and a filter element is installed in the dust removal chamber. There are two air inlets on the dust removal box 1, each air inlet is provided with a pneumatic valve 3, and each pneumatic valve 3 is controlled by a first electromagnetic valve D1. An air storage tank 4 is fixed on the outer wall of the dust removal box 1, and a back-blowing air pipe is pierced in the filter element, and the air storage tank 4 and the back-blowing air pipe are connected through a second electromagnetic valve D2.

[0023] Such as figure 2 As shown, the dust collector fan linkage control circuit includes motor comprehensive protector FR, AC contactor KM1, switching power supply and pulse controller.

[0024] The motor comprehensive protector FR is used for the overload and phase failure protection of the motor in the fan 2. The model of motor comprehensive pro...

Embodiment 2

[0041] The structure and principle of this embodiment are basically the same as that of Embodiment 1, and the basic similarities will not be described in detail, only the differences are described. The difference lies in: the fan linkage control circuit of the dust collector also includes The temperature controller T in 5, the temperature detection head of the temperature controller T is installed in the outer area of ​​the filter in the dust removal chamber, and the temperature controller is used for temperature monitoring and alarm in the dust removal chamber. The model of the temperature controller is REXD-C1000. The limit temperature value of the circuit is set in the temperature controller. During the normal operation of the dust collector, the temperature controller monitors the temperature.

[0042] Assume that when the temperature controller T detects that the temperature reaches the set value, the internal switch of the temperature controller T is turned on, the inte...

Embodiment 3

[0044] The structure and principle of this embodiment are basically the same as that of Embodiment 1 and Embodiment 2. The basic similarities will not be described in detail, only the differences will be described. The bottom of the dust removal box 1 is equipped with an ash unloader 6 communicating with the ash outlet. The fan linkage control circuit of the dust collector also includes a proximity switch S arranged on the ash unloader 6 for monitoring whether the ash unloader 6 is running, and the proximity switch S is connected in parallel with the pressure switch P; that is, the result that the ash unloader 6 cannot operate normally The proximity switch S monitors, and then the internal switch of the proximity switch S is turned on, the intermediate relay KA is energized, and then the motor of the fan 2 is also controlled to be powered off, the alarm lamp HR is turned on, and the first solenoid valve D1 is powered off.

Abstract

The invention provides a dust collector fan linkage control circuit, and belongs to the technical field of separation. The problem in the prior art that the dust collector is of low operation safety and the filter thereof has a short service life is solved. The dust collector fan linkage control circuit comprises an AC contactor, a pressure switch and a switching power supply. A start-stop switch is connected in series in a relay power supply circuit which is matched with the AC contactor in use. The AC contactor is connected in series in a power supply circuit of a motor. The pressure switch is electrically connected with the switching power supply, and the probe of the pressure switch is arranged inside an air storage tank. An intermediate relay KA is connected in series to a control line, which is connected with the negative output of the switching power supply, in the pressure switch. The normally closed contact of the intermediate relay is connected in series in the relay power supply circuit which is matched with the AC contactor in use. The dust collector fan linkage control circuit can stop running in time according to the temperature value inside a dust collector, the air pressure difference between the inside and outside of a filter and a fan for controlling the air pressure of compressed air in the air storage tank, so that hidden safety trouble can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of separation, and relates to a dust collector, in particular to a dust collector fan linkage control circuit. Background technique [0002] Dust collector is a device that separates dust from air flow, and it is a common equipment in industrial production such as boilers and polishing machines. [0003] There are many relevant documents about dust collectors, such as the dust collector (authorization announcement number CN201572578U) applied by the applicant before; a dust collector (authorization announcement number CN204193699U); dust collector (application publication number CN105289151A). The fan draws out the air inside the dust removal chamber, and a pressure difference is generated inside and outside the dust removal chamber; the air with dust enters the dust collector through the dust collection hood and the dust suction pipe, and is filtered by filter elements such as filter cartridges or cloth bag...
