Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, and in particular to a dome valve control method, device, equipment and medium. Background Art

[0002] As the environmental situation becomes increasingly severe, the stable operation of factory dust removal equipment plays a key role in the dust removal system's continued compliance with emission standards. There is an indispensable device in the dust removal system - the dome valve, which is located at the bottom of the ash bin and realizes periodic ash delivery through the pneumatic actuator switch.

[0003] The prior art is that the PLC controls the extension and retraction of the cylinder by controlling the solenoid valve to realize the opening and closing of the dome valve. When the cylinder is extended, the dome valve opens. At this time, a nut on the robotic arm triggers the mechanical switch to close. The closing of the mechanical switch triggers the mechanical linkage pneumatic valve to control the deflation of the sealing gasket and start dust discharge. When the cylinder is retracted, the dome valve closes. At this time, the nut on the robotic arm triggers the opening of the mechanical switch. The opening of the mechanical switch triggers the mechanical linkage pneumatic valve to control the inflation of the sealing gasket, thereby realizing the sealing of the dome valve by the sealing gasket.

[0004] However, in the prior art, the mechanical switch linked to the pneumatic valve causes the seal to be inflated before the dome valve is completely closed, and the dome valve is opened before the seal is completely deflated, which causes the seal to wear quickly and eventually causes the dome valve to fail. Therefore, how to reduce the wear of the seal is an urgent problem to be solved. Summary of the invention

[0065] The embodiment of the present application provides a dome valve control method to solve the technical problem in the prior art that the action of the mechanical switch linked to the pneumatic valve causes the sealing gasket to be inflated before the dome valve is completely closed, and the dome valve is opened before the sealing gasket is completely deflated, which causes the sealing gasket to wear quickly and eventually causes the dome valve to fail.

[0066] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0067] In the embodiment of the present application, in response to the opening signal of the dome valve, the dome valve is controlled to open to discharge the ash from the ash bin; when the ash discharge operation reaches the preset ash discharge time, a closing signal of the dome valve is generated; in response to the closing signal of the dome valve, the dome valve is controlled to close; after the dome valve is completely closed, the sealing gasket of the dome valve is controlled to start to inflate; after the dome valve is closed for the preset exhaust time, the sealing gasket of the dome valve is controlled to start to exhaust; after the dome valve is closed for the preset waiting time, an opening signal of the dome valve is generated, and the step of responding to the opening signal of the dome valve and controlling the dome valve to open to discharge the ash from the ash bin is returned. It can be seen that in the embodiment of the present application, the sealing gasket is controlled to inflate after the dome valve is completely closed, and the dome valve is controlled to open after the exhaust of the sealing gasket is completed, which can greatly reduce the wear of the sealing gasket and extend the life cycle of the sealing gasket, that is, extend the life cycle of the dome valve, reduce the number of failures of the dome valve, reduce the number of frequent alarms of the dust removal system, and reduce the consumption of equipment costs of enterprises.

[0068] The solution provided in the embodiment of the present application can extend the service life of the dome valve and ensure that the dust removal system can continue to operate stably for a longer period of time; there is no need to replace the more expensive dome valve, which saves both the cost of spare parts and the cost of structural modification; the control system is independent and does not change the original control logic and program, so it is easy to implement and does not require downtime.

[0069] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0070] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0071] As the environmental situation becomes increasingly severe, the stable operation of factory dust removal equipment plays a key role in the dust removal system's continued compliance with emission standards. There is an indispensable device in the dust removal system - the dome valve, which is located at the bottom of the ash bin and realizes periodic ash delivery through the pneumatic actuator switch.

[0072] The ash conveying action is executed according to the set cycle, and it is generally set to continuously convey ash for 4 seconds every 60 seconds. The dome valve operates frequently. There is a certain problem in the coordination between the switching action of the dome valve and the inflation and deflation action of its sealing gasket, that is, when the dome valve is closed, a component on the robot arm will trigger the mechanical limit switch valve to open, and the sealing gasket will be inflated. At the moment the dome valve opens, the mechanical limit switch valve is closed and the sealing gasket is exhausted.

[0073] The prior art is that the PLC controls the extension and retraction of the cylinder by controlling the solenoid valve to realize the opening and closing of the dome valve. When the cylinder is extended, the dome valve opens. At this time, a nut on the robotic arm triggers the mechanical switch to close. The closing of the mechanical switch triggers the mechanical linkage pneumatic valve to control the deflation of the sealing gasket and start dust discharge. When the cylinder is retracted, the dome valve closes. At this time, the nut on the robotic arm triggers the opening of the mechanical switch. The opening of the mechanical switch triggers the mechanical linkage pneumatic valve to control the inflation of the sealing gasket, thereby realizing the sealing of the dome valve by the sealing gasket.

[0074] However, in the prior art, the mechanical switch linked to the pneumatic valve causes the seal to be inflated before the dome valve is completely closed, and the dome valve opens before the seal is completely deflated. This problem causes the seal to wear out quickly, shortening its life cycle and eventually causing the dome valve to fail, which not only causes the dust removal system to frequently sound alarms, but also causes the company to significantly increase its equipment costs. Therefore, how to reduce the wear of the seal is an urgent problem to be solved.

[0075] In order to solve the above problems, the present application provides the following embodiments: Figure 1 A dome valve control method is shown, the method comprising steps S11 to S16.

[0076] Step S11, in response to an opening signal of the dome valve, controlling the dome valve to open to discharge ash from the ash bin;

[0077] Step S12, when the ash discharge operation reaches a preset ash discharge time, a closing signal of the dome valve is generated;

[0078] Step S13, in response to a closing signal of the dome valve, controlling the dome valve to close;

[0079] Step S14, after the dome valve is completely closed, controlling the sealing gasket of the dome valve to start inflating;

[0080] Step S15, after the dome valve is closed for a preset exhaust time, the sealing gasket of the dome valve is controlled to start exhausting;

[0081] Step S16, after the dome valve is closed for a preset waiting time, an opening signal of the dome valve is generated, and the process returns to execute the step of controlling the dome valve to open in response to the opening signal of the dome valve to discharge ash from the ash bin.

[0082] A dome valve control method provided in an embodiment of the present application may be executed by a dome valve controller, or may be executed by a cloud server that communicates with the dome valve controller, and the embodiment of the present application does not impose any limitation on this.

[0083] Before describing a dome valve control method provided in an embodiment of the present application, the control system of the dome valve is described as follows.

[0084] like Figure 2 and Figure 3 As shown, or as Figure 4 and Figure 5 As shown, the dome valve control system includes a solenoid valve, a cylinder, a mechanical arm, a mechanical limit switch, a sealing gasket, an electric push rod, a proximity switch and other components.

[0085] The proximity switch is used to detect whether the robot arm has closed the dome valve in place. The electric push rod is installed in conjunction with the mechanical limit conduction switch. The electric push rod can trigger the mechanical limit conduction switch and change the state of the mechanical limit conduction switch.

[0086] in Figure 2 and Figure 3 Characterize the status of each component of the dome valve when it is in the closed state. Figure 4 and Figure 5 Characterizes the status of each component when the dome valve is in the open state.

[0087] When the solenoid valve is energized, Figure 2 and Figure 3 The dome valve is shown in the closed state. When the solenoid valve is de-energized, Figure 4 and Figure 5 The dome valve is open as shown. When the solenoid valve switches from the energized state to the de-energized state, the components will Figure 2 The state transitions to Figure 4 status, and from Figure 3 The state changes to Figure 5 On the contrary, when the solenoid valve switches from the de-energized state to the energized state, the components will Figure 4 The state transitions to Figure 2 status, and from Figure 5 The state changes to Figure 3 state.

[0088] Now continue combining Figure 6, a dome valve control method provided in an embodiment of the present application is described as follows.

[0089] Regarding step S11 , in response to an opening signal of the dome valve, the dome valve is controlled to open to perform an ash discharge operation on the ash bin.

[0090] In response to the opening signal of the dome valve, the solenoid valve of the mechanical arm controlling the dome valve loses power, so that the mechanical arm controls the dome valve to start switching to an open state and controls the ash discharge timer to start timing.

[0091] Before the ash discharge timer reaches a preset ash discharge time length P (eg, 4 seconds), the dome valve is controlled to remain in an open state to perform ash discharge operations inside the ash bin.

[0092] Regarding step S12, when the ash discharge operation reaches a preset ash discharge time, a closing signal of the dome valve is generated.

[0093] When the ash discharge timer reaches a preset ash discharge time length P (eg, 4 seconds), a closing signal for the dome valve is generated.

[0094] Regarding step S13, in response to the closing signal of the dome valve, the dome valve is controlled to close.

[0095] In response to the closing signal, the solenoid valve of the mechanical arm controlling the dome valve is energized, so that the mechanical arm controls the dome valve to start switching to a closed state.

[0096] Regarding step S14, after the dome valve is completely closed, the sealing gasket of the dome valve is controlled to start inflating.

[0097] A trigger signal generated after the proximity switch is triggered by the mechanical arm of the dome valve is received, wherein the trigger signal indicates that the dome valve is completely closed; after the dome valve is completely closed, the sealing pad of the dome valve is controlled to start inflating.

[0098] Specifically, after the dome valve is completely closed, the process of controlling the sealing gasket of the dome valve to start inflating includes:

[0099] After the dome valve is fully closed, the control wait timer starts timing;

[0100] When the waiting timer reaches the preset inflation start time N (for example, 10 seconds), the electric push rod is controlled to extend until the electric push rod triggers the mechanical limit conduction switch to turn on, triggering the sealing gasket of the dome valve to start inflation.

[0101] Regarding step S15, after the dome valve is closed for a preset exhaust time, the sealing gasket of the dome valve is controlled to start exhausting.

[0102] When the waiting timer reaches the preset exhaust time M (for example, 49 seconds), the electric push rod is controlled to retract until the electric push rod leaves the mechanical limit switch, so that the mechanical limit switch is closed to trigger the sealing gasket of the dome valve to start exhausting.

[0103] Regarding step S16, after the dome valve is closed for a preset waiting time, an opening signal of the dome valve is generated, and the process returns to execute the step of controlling the dome valve to open in response to the opening signal of the dome valve to discharge ash from the ash bin.

[0104] After the dome valve is closed for a preset waiting time K (for example, 1 second, K=TMN, T is, for example, 60 seconds), an opening signal for the dome valve is generated, and the process returns to execute the step of responding to the opening signal of the dome valve and controlling the dome valve to open to discharge ash from the ash bin, that is, returns to execute step S11 to start the next round of ash discharge cycle.

[0105] In addition, when the electric push rod does not return an inflation or exhaust success signal after being extended or retracted, an alarm is sounded and the alarm information is recorded.

[0106] In summary, in the embodiment of the present application, in response to the opening signal of the dome valve, the dome valve is controlled to open to discharge the ash from the ash bin; when the ash discharge operation reaches the preset ash discharge time, a closing signal of the dome valve is generated; in response to the closing signal of the dome valve, the dome valve is controlled to close; after the dome valve is completely closed, the sealing gasket of the dome valve is controlled to start to inflate; after the dome valve is closed for the preset exhaust time, the sealing gasket of the dome valve is controlled to start exhausting; after the dome valve is closed for the preset waiting time, an opening signal of the dome valve is generated, and the step of responding to the opening signal of the dome valve and controlling the dome valve to open to discharge the ash from the ash bin is returned. It can be seen that in the embodiment of the present application, the sealing gasket is controlled to inflate after the dome valve is completely closed, and the dome valve is controlled to open after the exhaust of the sealing gasket is completed, which can greatly reduce the wear of the sealing gasket and extend the life cycle of the sealing gasket, that is, extend the life cycle of the dome valve, reduce the number of failures of the dome valve, reduce the number of frequent alarms of the dust removal system, and reduce the consumption of equipment costs of enterprises.

[0107] The solution provided in the embodiment of the present application can extend the service life of the dome valve and ensure that the dust removal system can continue to operate stably for a longer period of time; there is no need to replace the more expensive dome valve, which saves both the cost of spare parts and the cost of structural modification; the control system is independent and does not change the original control logic and program, so it is easy to implement and does not require downtime.

[0108] Now combined Figure 6 The following is an overall description of a dome valve control method provided in an embodiment of the present application.
