Description

Technical Field

[0001] This utility model relates to the field of waste incineration equipment technology, and in particular to a water-sealed intelligent control device for ash discharge from an incinerator. Background Technology

[0002] After waste incineration, incineration residue is produced, which needs to be discharged. The discharge device usually requires a water seal, the main functions of which are to achieve sealing, cooling, pressure stabilization, and protection of the discharge channel. In actual operation, water is mainly replenished by the sedimentation tank. However, the sedimentation tank water contains a lot of impurities, which can easily cause blockage of the water supply pipeline of the discharge machine. Impurities in the pipeline may not only lead to insufficient water supply to the discharge machine, but may also cause the pneumatic solenoid valve connected to the pipeline to malfunction, making it impossible to shut off and replenish water in time. In addition, the staff needs to constantly monitor the liquid level of the discharge machine, which is a waste of manpower and resources. The combination of these factors can lead to poor water sealing effect. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a smart water-sealing control device for incinerator slag discharge that can replenish water promptly and prevent pipeline blockage.

[0004] The technical solution of this utility model is as follows: A water-sealed intelligent control device for slag discharge from an incinerator includes a sedimentation tank, a water supply pipe connected to the sedimentation tank, a filter screen connected to the sedimentation tank, a slag discharge machine connected to the water supply pipe, a pneumatic solenoid valve connected to the water supply pipe, a float valve connected to the slag discharge machine, and a controller. When the liquid level in the slag discharge machine is lower than the position of the float valve, the pneumatic solenoid valve is in the open state; when the liquid level in the slag discharge machine is higher than the position of the float valve, the pneumatic solenoid valve is in the closed state. The controller is electrically connected to the pneumatic solenoid valve and the float valve respectively.

[0005] Using the above technical solution, firstly, the controller controls the pneumatic solenoid valve to be in the open state, allowing water from the sedimentation tank to flow to the slag discharge machine through the water supply pipe. The water in the sedimentation tank is first filtered through a filter screen, reducing impurities flowing into the water supply pipe and preventing blockages in the water supply pipe or pneumatic solenoid valve during use. Furthermore, since the slag discharge machine is equipped with a float valve, when the liquid level in the slag discharge machine reaches the float valve's level, the water in the slag discharge machine causes the float on the float valve to rise. The float valve sends an electrical signal to the controller, which then controls the pneumatic solenoid valve to open, thus completing the automatic water supply function. Compared to the traditional method of manually monitoring the liquid level in the slag discharge machine, this device, by controlling water supply through a float valve, greatly improves the automation level of the equipment, reduces the accumulation of scum on the float that could lead to equipment malfunction, and ensures timely water supply to the equipment.

[0006] A further feature of this invention is that the water supply pipe is provided with a first air inlet pipe connected to the water supply pipe and a first air cannon connected to the first air inlet pipe. The connection position between the air outlet of the first air inlet pipe and the water supply pipe is located above the connection position between the pneumatic solenoid valve and the water supply pipe. The controller is electrically connected to the first air cannon.

[0007] Using the above technical solution, after the equipment has been running for a period of time, some impurities in the water may cause blockage of the water supply pipe or the pneumatic solenoid valve. At this time, the staff can manually control the first air cannon to work. The first air cannon emits pulsed high-pressure airflow to clean the inside of the water supply pipe and the pneumatic solenoid valve. This can quickly clean and maintain the device without stopping the machine for maintenance, thereby improving the working efficiency of the equipment.

[0008] A further feature of this invention is that the slag discharger is equipped with a second air inlet pipe and a second air cannon connected to the second air inlet pipe. The air outlet of the second air inlet pipe is aligned with the location of the float valve. The controller is electrically connected to the second air cannon.

[0009] With the above technical solution, since the slag discharger is equipped with a second air inlet pipe and a second air cannon connected to the second air inlet pipe, after the equipment has been working for a period of time, the controller will control the second air cannon to start working. The pulsed high-pressure airflow emitted by the second air cannon will clean the scum on the surface of the float valve, thereby avoiding the float valve from malfunctioning and affecting the automatic water replenishment operation.

[0010] A further feature of this invention is that a first electromagnetic ball valve and a second electromagnetic ball valve are respectively provided on the first air intake pipe and the second air intake pipe, and the first electromagnetic ball valve and the second electromagnetic ball valve are electrically connected to the controller.

[0011] Using the above technical solution, when the first or second air cannon is not required to operate, the controller controls the first and second electromagnetic ball valves to be in the closed state, thereby improving the pressure stability inside the water supply pipe and the slag discharge machine, thus ensuring the sealing of the slag discharge machine. When it is necessary to clean the water supply pipe and the pneumatic solenoid valve, the controller controls the first electromagnetic ball valve to be in the open state. When it is necessary to clean the float valve, the controller controls the second electromagnetic ball valve to be in the open state. Attached Figure Description

Detailed Implementation

[0014] like Figure 1 As shown, a water-sealed intelligent control device for slag discharge from an incinerator includes a sedimentation tank 1, a water supply pipe 2 connected to the sedimentation tank 1, a filter screen 3 connected to the sedimentation tank 1, a slag discharge machine 4 connected to the water supply pipe 2, a pneumatic solenoid valve 5 connected to the water supply pipe 2, a float valve 6 connected to the slag discharge machine 4, and a controller 7. When the liquid level in the slag discharge machine 4 is lower than the position of the float valve 6, the pneumatic solenoid valve 5 is in the open state; when the liquid level in the slag discharge machine 4 is higher than the position of the float valve 6, the pneumatic solenoid valve 5 is in the closed state. The controller 7 is electrically connected to the pneumatic solenoid valve 5 and the float valve 6 respectively.

[0015] First, the controller 7 controls the pneumatic solenoid valve 5 to be in the open state, so that the water in the sedimentation tank 1 flows to the slag discharge machine 4 through the water supply pipe 2. The water in the sedimentation tank 1 is first filtered by the filter screen 3, thereby reducing impurities flowing into the water supply pipe 2 and preventing blockage of the water supply pipe 2 or the pneumatic solenoid valve 5 during use. In addition, since the slag discharge machine 4 is equipped with a float valve 6, when the liquid level in the slag discharge machine 4 reaches the liquid level of the float valve 6, the water in the slag discharge machine 4 will cause the float on the float valve 6 to rise. The float valve 6 sends an electrical signal to the controller 7, and the controller 7 controls the pneumatic solenoid valve 5 to open, thereby completing the automatic water replenishment function. Compared with the traditional method of having staff manually monitor the liquid level in the slag discharge machine 4, this device controls the water replenishment through the float valve 6, greatly improving the automation level of the equipment, reducing the accumulation of scum on the float that could lead to equipment failure, and ensuring that the equipment can be replenished with water in a timely manner.

[0016] The water supply pipe 2 is provided with a first air inlet pipe 8 and a first air cannon 9 connected to the first air inlet pipe 8. The connection position between the air outlet of the first air inlet pipe 8 and the water supply pipe 2 is located above the connection position between the pneumatic solenoid valve 5 and the water supply pipe 2. The controller 7 is electrically connected to the first air cannon 9.

[0017] After the equipment has been running for a period of time, some impurities in the water may cause blockage of the water supply pipe 2 or the pneumatic solenoid valve 5. At this time, the staff can control the first air cannon 9 to work through the manual controller 7. The first air cannon 9 emits pulsed high-pressure airflow to clean the inside of the water supply pipe 2 and the pneumatic solenoid valve 5. This allows for quick cleaning and maintenance of the device without downtime, thereby improving the working efficiency of the equipment.

[0018] The slag discharge machine 4 is equipped with a second air inlet pipe 10 and a second air cannon 11 connected to the second air inlet pipe 10. The air outlet of the second air inlet pipe 10 is aligned with the position of the float valve 6. The controller 7 is electrically connected to the second air cannon 11.

[0019] Since the slag discharger 4 is equipped with a second air inlet pipe 10 and a second air cannon 11 connected to the second air inlet pipe 10, after the equipment has been working for a period of time, the controller 7 controls the second air cannon 11 to start working. The pulsed high-pressure airflow emitted by the second air cannon 11 cleans the scum on the surface of the float valve 6, thereby preventing the float valve 6 from malfunctioning and affecting the automatic water replenishment work.

[0020] The first air intake pipe 8 and the second air intake pipe 10 are respectively provided with a first electromagnetic ball valve 12 and a second electromagnetic ball valve 13, and the first electromagnetic ball valve 12 and the second electromagnetic ball valve 13 are electrically connected to the controller 7.

[0021] When the first air cannon 9 or the second air cannon 11 is not required to operate, the controller 7 controls the first solenoid ball valve 12 and the second solenoid ball valve 13 to be in the closed state, thereby improving the pressure stability inside the water supply pipe 2 and the slag discharge machine 4, thus ensuring the sealing of the slag discharge machine 4. When it is necessary to clean the water supply pipe 2 and the pneumatic solenoid valve 5, the controller 7 controls the first solenoid ball valve 12 to be in the open state. When it is necessary to clean the float valve 6, the controller 7 controls the second solenoid ball valve 13 to be in the open state.
