Description

Technical Field

[0001] This utility model relates to the technical field of flue gas treatment equipment, and in particular to a cleaning device for an activated carbon injection device. Background Technology

[0002] In existing technologies, mainstream waste incineration processes typically employ a design of incinerator + secondary combustion chamber + waste heat recovery + flue gas purification. During flue gas purification, deacidifying agents are usually used to adsorb harmful substances in the flue gas, ensuring emissions meet standards. Common deacidifying agents include activated carbon. However, existing activated carbon injection devices have the following problems: First, during injection, activated carbon easily mixes with moisture in the flue gas, causing blockage at the hopper outlet, preventing stable and continuous injection of activated carbon into the flue. Second, once activated carbon condenses with moisture and dries at the outlet, the condensed activated carbon becomes difficult to clean. Third, in existing technologies, cleaning the flue typically requires shutdown for maintenance, resulting in high maintenance costs. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a cleaning device for activated carbon spraying equipment that can prevent outlet blockage and automatically and efficiently clean the outlet. The technical solution of this utility model is as follows: A cleaning device for an activated carbon injection device includes a base, an activated carbon hopper connected to the base, a flue connected to the activated carbon hopper, a fixed frame connected to the base, a sliding base slidably connected to the fixed frame, a connecting block fixedly connected to the sliding base, a cleaning brush head fixedly connected to the connecting block, a hydraulic cylinder for driving the sliding base to slide vertically, and a controller. The flue has a connection port, an inlet, and an outlet. One end of the activated carbon hopper is connected to the inlet. The shape and size of the connection port are adapted to the connecting block. The connecting block is slidably connected to the connection port. When the sliding base is in its initial state, the cleaning brush head does not contact the inlet. After the sliding base slides a certain distance, the cleaning brush head can contact the inlet. The cleaning brush head has a certain elasticity, and its width is adapted to the diameter of the inlet. The controller is electrically connected to the hydraulic cylinder.

[0004] Using the above technical solution, when activated carbon condensate blocks the feed inlet of the flue, the controller controls the sliding base to move back and forth vertically. Since the cleaning brush head is fixedly connected to the connecting block, and the connecting block is fixedly connected to the sliding base, the cleaning brush head can repeatedly clean the feed inlet, thereby removing the blockage. Because the width of the cleaning brush head is matched with the diameter of the feed inlet, it can be ensured that the feed inlet is cleaned. The blockage that leaves the feed inlet will slide down the flue into the discharge outlet and leave the flue. After the cleaning work is completed, the controller controls the hydraulic cylinder to drive the sliding base to move vertically downward a certain distance, so that the position of the cleaning brush head does not coincide with the position of the feed inlet, ensuring that it will not affect the activated carbon injection work. The cleaning work can be carried out without stopping the activated carbon injection device for maintenance, which greatly reduces the cleaning cost.

[0005] A further feature of this invention is that a rotating shaft and a first rotary motor for driving the rotating shaft to rotate are provided between the connecting block and the sliding base, and the controller is electrically connected to the first rotary motor.

[0006] Using the above technical solution, when cleaning the feed inlet, firstly, the controller controls the hydraulic cylinder to drive the sliding base to move vertically upward, so that the cleaning brush head corresponds to the feed inlet. Then, the controller controls the first rotary motor to drive the rotating shaft to rotate, thereby improving the cleaning force and cleaning effect of the cleaning brush head on the feed inlet.

[0007] A further feature of this invention is that a sealing gasket is fixedly connected to the connection port, the outer surface shape of the sealing gasket is adapted to the shape and size of the inner wall of the connection port, and the inner wall shape of the sealing gasket is adapted to the shape and size of the outer surface of the connecting block.

[0008] By adopting the above technical solution, since the outer surface shape of the sealing gasket matches the inner wall shape and size of the connection port, and the inner wall shape of the sealing gasket matches the outer surface shape and size of the connecting block, the sealing performance of the connection between the connecting block and the connection port can be greatly improved, preventing activated carbon from leaking from the connection and ensuring that the activated carbon can flow smoothly into the flue.

[0009] Further features of this invention: The flue is also provided with a connecting rod movably connected to the flue, a spiral blade connected to the connecting rod, a cleaning pad connected to the spiral blade, and a second rotary motor for driving the connecting rod to rotate. The central axis of the connecting rod is coaxial with the central axis of the flue. The cleaning pad is in contact with the inner wall of the flue. The connecting rod and the spiral blade do not contact the cleaning brush head. The controller is electrically connected to the second rotary motor.

[0010] By adopting the above technical solution, since the cleaning pad is in contact with the inner wall of the flue, the second rotary motor can be controlled by the controller to drive the connecting rod to rotate, thereby driving the spiral blades to rotate continuously. The spiral blades can drive the cleaning pad to continuously rub against the inner wall of the flue, thereby cleaning the inner wall of the flue, which can further improve the cleaning effect of the device.

Detailed Implementation

[0013] like Figure 1 As shown, a cleaning device for an activated carbon injection apparatus includes a base 1, an activated carbon hopper 2 connected to the base 1, a flue 3 connected to the activated carbon hopper 2, a fixed frame 4 connected to the base 1, a sliding base 5 slidably connected to the fixed frame 4, a connecting block 6 fixedly connected to the sliding base 5, a cleaning brush head 7 fixedly connected to the connecting block 6, a hydraulic cylinder 8 for driving the sliding base 5 to slide vertically, and a controller 9. The flue 3 is provided with a connection port 10, an inlet 11, and an outlet 12. The feed inlet 12 is connected to the feed port 11 at one end of the activated carbon hopper. The shape and size of the connecting port 10 are adapted to the connecting block 6. The connecting block 6 is slidably connected to the connecting port 10. When the sliding base 5 is in the initial state, the cleaning brush head 7 does not contact the feed port 11. After the sliding base 5 slides a certain distance, the cleaning brush head 7 can contact the feed port 11. The cleaning brush head 7 has a certain elasticity. The width of the cleaning brush head 7 is adapted to the diameter of the feed port 11. The controller 9 is electrically connected to the hydraulic cylinder 8.

[0014] When activated carbon condensate blocks the feed inlet 11 of flue 3, the controller 9 controls the sliding base 5 to move back and forth vertically. Since the cleaning brush head 7 is fixedly connected to the connecting block 6 and the connecting block 6 is fixedly connected to the sliding base 5, the cleaning brush head 7 can repeatedly clean the feed inlet 11 to remove the blockage. Because the width of the cleaning brush head 7 is matched with the diameter of the feed inlet 11, it can be ensured that the feed inlet 11 is cleaned. The blockage that leaves the feed inlet 11 will slide down the flue 3 into the discharge outlet 12 and leave the flue 3. After the cleaning work is completed, the controller 9 controls the hydraulic cylinder 8 to drive the sliding base 5 to move vertically downward a certain distance so that the position of the cleaning brush head 7 does not coincide with the position of the feed inlet 11, ensuring that it will not affect the activated carbon injection work. The cleaning work can be carried out without stopping the activated carbon injection device for maintenance, which greatly reduces the cleaning cost.

[0015] A rotating shaft 13 and a first rotary motor 14 for driving the rotating shaft 13 to rotate are provided between the connecting block 6 and the sliding base 5. The controller 9 is electrically connected to the first rotary motor 14. When cleaning the feed inlet 11, firstly, the controller 9 controls the hydraulic cylinder 8 to drive the sliding base 5 to move vertically upward, so that the cleaning brush head 7 corresponds to the position of the feed inlet 11. Then, the controller 9 controls the first rotary motor 14 to drive the rotating shaft 13 to rotate, thereby improving the cleaning force and cleaning effect of the cleaning brush head 7 on the feed inlet 11.

[0016] A sealing gasket 15 is fixedly connected to the connection port 10. The outer surface shape of the sealing gasket 15 is adapted to the inner wall shape and size of the connection port 10, and the inner wall shape of the sealing gasket 15 is adapted to the outer surface shape and size of the connecting block 6.

[0017] Since the outer surface shape of the sealing gasket 15 is adapted to the inner wall shape and size of the connection port 10, and the inner wall shape of the sealing gasket 15 is adapted to the outer surface shape and size of the connecting block 6, the sealing performance of the connection between the connecting block 6 and the connection port 10 can be greatly improved, preventing activated carbon from leaking from the connection and ensuring that the activated carbon can flow smoothly into the flue 3.

[0018] The flue 3 is also provided with a connecting rod 16 movably connected to the flue 3, a spiral blade 17 connected to the connecting rod 16, a cleaning pad 18 connected to the spiral blade 17, and a second rotary motor 19 for driving the connecting rod 16 to rotate. The central axis of the connecting rod 16 is coaxial with the central axis of the flue 3. The cleaning pad 18 is in contact with the inner wall of the flue 3. The connecting rod 16 and the spiral blade 17 do not contact the cleaning brush head 7. The controller 9 is electrically connected to the second rotary motor 19.

[0019] Since the cleaning pad 18 is in contact with the inner wall of the flue 3, the second rotary motor 19 can be controlled by the controller 9 to drive the connecting rod 16 to rotate, thereby driving the spiral blade 17 to rotate continuously. The spiral blade 17 can drive the cleaning pad 18 to continuously rub against the inner wall of the flue 3, thereby cleaning the inner wall of the flue 3, which can further improve the cleaning effect of the device.
