Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and particularly relates to a device for detecting the operation state of ash discharging of a dust collector. Background Art

[0002] At present, the bag dust collector is used in the dust removal system of cigarette factories. It is a dry dust removal device and is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag dust collector, the dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained and the gas is purified. The structure of the bag dust collector mainly consists of an upper box body, a middle box body, a lower box body (ash hopper), a dust cleaning system and an ash discharging mechanism, etc. However, the existing ash discharging mechanism of the bag dust collector is not provided with an operation monitoring device, and there is no way to give a prompt alarm when the ash discharging of the bag dust collector is abnormal. It can only rely on manual inspection for detection and monitoring, resulting in an increase in production costs. Content of the Utility Model

[0003] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a device for detecting the operation state of ash discharging of a dust collector to solve the above problems. The specific technical solutions are as follows:

[0005] An ash discharging operation unit, the ash discharging operation unit includes a signal of the ash discharging operation of the dust collector;

[0006] An ash discharging detection unit, the ash discharging detection unit includes a rotating shaft induction component and a rotating shaft signal acquisition component connected to the rotating shaft induction component. The rotating shaft induction component is installed at the position of the ash discharging rotating shaft and rotates synchronously with the ash discharging rotating shaft. The rotating shaft signal acquisition component is installed on the ash discharging side plate. The rotating shaft signal acquisition component can collect the actual rotation speed signal of the ash discharging rotating shaft through the rotating shaft induction component;

[0007] A signal processing unit, the signal processing unit can compare, analyze and process the signal of the ash discharging operation of the dust collector and the actual rotation speed signal of the ash discharging rotating shaft and output the analyzed and processed information;

[0008] An ash discharging alarm unit, the ash discharging alarm unit receives the information output by the signal processing unit to judge whether a fault occurs in the ash discharging of the dust collector and gives a corresponding prompt alarm.

[0009] Preferably, the rotating shaft signal acquisition component includes an inductive proximity switch, a pin-type wiring plug, and a fixed base. The fixed base is connected to the ash discharge side plate, the inductive proximity switch is connected to the fixed base, the pin-type wiring plug is connected to the inductive proximity switch, and the inductive proximity switch can collect the signal of the rotating shaft induction component.

[0010] Preferably, the fixed base and the rotating shaft induction component are arranged on the same side of the ash discharge rotating shaft. The fixed base is parallel to the ash discharge rotating shaft, and the inductive proximity switch is perpendicularly arranged with respect to the fixed base.

[0011] Preferably, the distance between the inductive proximity switch and the rotating shaft induction component is 3 mm to 5 mm.

[0012] Preferably, the rotating shaft induction component is a protruding metal block.

[0013] Compared with the existing technology, in the present utility model, a rotating shaft induction component is installed on the ash discharge rotating shaft of the ash discharge mechanism of the dust collector, and a rotating shaft signal acquisition component is installed on the ash discharge side plate of the ash discharge mechanism of the dust collector. The actual operating speed of the ash discharge mechanism of the dust collector can be measured in real time by using the rotating shaft induction component and the rotating shaft signal acquisition component. The set ash discharge operation unit includes the rated speed of the ash discharge rotating shaft in the ideal state when the dust collector operates the ash discharge mechanism. The signal processing unit compares the detected actual operating speed with the rated speed. If the difference between the compared data exceeds the allowable error, the ash discharge alarm unit will determine that the ash discharge mechanism of the dust collector has a non-coaxial rotation situation, and then it will be determined as a fault state. In this way, the ash discharge alarm unit will give a prompt alarm to achieve the purpose of detecting the operating state of the ash discharge of the dust collector, and there is no need to detect and monitor the operating condition of the ash discharge mechanism through manual inspection.

[0025] An ash discharging operation unit 1, the ash discharging operation unit 1 includes a dust removal ash discharging operation signal, the dust removal ash discharging operation signal specifically includes the rated speed of the ash discharging rotating shaft 100, the ash discharging operation unit 1 is specifically an information operation unit in the PLC control system, the information operation unit is specifically a register, and the information operation unit contains various state information during the operation of the ash discharging mechanism of the dust collector.

[0026] An ash discharging detection unit 2, the ash discharging detection unit 2 includes a rotating shaft induction component 21 and a rotating shaft signal acquisition component 22 connected to the rotating shaft induction component 21, the rotating shaft induction component 21 is installed at the position of the ash discharging rotating shaft 100 and rotates synchronously with the ash discharging rotating shaft 100, the rotating shaft signal acquisition component 22 is installed on the ash discharging side plate 200, and the rotating shaft signal acquisition component 22 can collect the actual speed signal of the ash discharging rotating shaft 100 through the rotating shaft induction component 21.

[0027] Specifically, the actual speed signal of the ash discharging rotating shaft 100 collected by the rotating shaft signal acquisition component 22 will be transmitted to the signal processing unit in the PLC control system.

[0028] A signal processing unit 3, the signal processing unit 3 can perform comparative analysis processing on the dust removal ash discharging operation signal and the actual speed signal of the ash discharging rotating shaft 100 and output the analyzed and processed information. Specifically, the signal processing unit 3 adopts a PLC control system, and the PLC control system can perform comparative analysis processing on the dust removal ash discharging operation signal and the actual speed signal of the ash discharging rotating shaft 100, and finally output the analysis result.

The pin-type wiring plug 222 is connected to the inductive proximity switch 221. The inductive proximity switch 221 can collect the signal of the shaft induction component 21.

[0031] Specifically, the inductive proximity switch 221 is a non-contact position detection device. It uses the principle of electromagnetic induction to detect the approach or departure of a metal object. When the shaft induction component 21 rotates with the ash discharge shaft 100, the position between the shaft induction component 21 and the inductive proximity switch 221 is constantly changing.

[0034] As a preferred embodiment, the rotating shaft sensing component 21 is a raised metal block. The raised metal block is arranged on the ash discharging rotating shaft 100 and rotates synchronously with the ash discharging rotating shaft 100. When the rotating shaft sensing component 21 is a metal block, the rotating shaft signal acquisition component 22 adopts an inductive proximity switch 221. In some other embodiments, when measuring the number of rotations of the ash discharging rotating shaft 100, an encoder running coaxially can be used to detect and calculate the rotational speed.
