Description

Technical Field

[0001] This utility model relates to the technical field of kiln supporting devices, specifically a blockage clearing device with rotation and telescopic functions. Background Technology

[0002] When a kiln is in the calcination process, a gas analysis device that can enter and exit the kiln is needed to collect the gas inside the kiln and analyze its composition (O2, CO, SO2, NOx, etc.). This allows for a scientific, effective, and accurate analysis of the combustion state inside the kiln, which in turn controls the amount of coal injected and the amount of air (O2) injected, maintaining their ratio within a reasonable range. This ensures that the kiln achieves a more ideal combustion state, guaranteeing both the calcination efficiency and the energy-saving and emission-reduction effects of the kiln.

[0003] Typically, gas analyzers use a probe as a carrier, driven by a cylinder, to enter and exit the kiln through a pre-embedded pipe fixed to the furnace wall. Because the kiln's interior is a high-temperature, high-dust environment, over a prolonged period, a large amount of dust diffuses into the pre-embedded pipe. External air and moisture also enter the pipe, causing dust to accumulate and clump on the inner wall upon cooling and contact with moisture, resulting in blockage. Therefore, regular cleaning of the pre-embedded pipe is necessary.

[0004] Currently, there are two main methods for clearing blockages. One is manual cleaning, where workers use a long-handled brush to insert into the embedded pipe to remove the clumps of dust. Due to the high temperature and dust environment inside the kiln, this method is dangerous, inefficient, and labor-intensive, and has been gradually abandoned. The other method uses a cylinder-driven cleaning rod to extend into the embedded pipe to remove the clumps of dust. However, because the dust clumps are highly adhesive, this method is also limited in effectiveness. Utility Model Content

[0005] The purpose of this invention is to overcome the defects and deficiencies of the existing technology and provide a cleaning device with rotation and telescopic functions, which can effectively clean the dust that has accumulated on the inner wall of the pre-embedded pipe to achieve a good cleaning effect. At the same time, it can send the cleaned dust back into the kiln to reduce the risk of dust escaping.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A blockage-clearing device with rotation and extension functions includes a cylinder, a motor, and a blockage-clearing rod. The cylinder includes a cylinder barrel, a piston, and a piston rod. The two ends of the piston rod extend from the two ends of the cylinder barrel, respectively.

The front end of the blockage-clearing rod is rotatably mounted on the front end of the piston rod, and the rear end of the blockage-clearing rod is shaft-connected to the output shaft of the motor. The blockage-clearing rod is driven by the cylinder to extend and retract, and is driven by the motor to rotate.

[0008] Furthermore, the front end of the unblocking rod is rotatably mounted to the front end of the piston rod via a bearing.

[0009] Furthermore, a housing is fixedly connected to the rear end of the piston rod, and a mounting base is fixedly installed inside the housing.

[0010] Furthermore, the motor is fixedly installed at the rear end of the mounting base, and the front end of the housing and the interior of the mounting base are both provided with through holes that communicate with each other.

[0019] Figure 2 This is a schematic diagram of the structure of the present invention in use. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1 , 2 A blockage-clearing device with rotation and extension functions includes a cylinder, a motor 1, and a blockage-clearing rod 2. The cylinder includes a cylinder barrel 3, a piston 4, and a piston rod 5. The two ends of the piston rod 5 extend from the two ends of the cylinder barrel 3 respectively. The piston rod 5 is hollow inside. The blockage-clearing rod 2 passes through the interior of the piston rod 5 from front to back, and the front end of the blockage-clearing rod 2 is rotatably mounted on the front end of the piston rod 5. The rear end of the blockage-clearing rod 2 is shaft-connected to the output shaft of the motor 1. The blockage-clearing rod 2 is driven by the cylinder to extend and retract, and is driven by the motor 1 to rotate.

[0022] In this invention, the front end of the unblocking rod 2 is rotatably mounted on the front end of the piston rod 5 via a bearing 6.

[0023] In this utility model, the rear end of the piston rod 5 is fixedly connected to the housing 7, and the housing 7 is fixedly installed with the mounting base 8.

[0024] In this utility model, the motor 1 is fixedly installed at the rear end of the mounting base 8. The front end of the housing 7 and the interior of the mounting base 8 are provided with through holes 9 that are interconnected. The rear end of the unblocking rod 2 and the output shaft of the motor 1 both extend into the through holes 9 and are connected by a coupling 10.

[0025] Thus, the forward and backward movement of the piston rod 5 drives the unblocking rod 2 to move forward and backward.

[0026] In this utility model, a guide rod 11 is fixedly connected to the front end of the housing 7, and a guide hole 12 is provided at the rear end of the cylinder 3. The guide rod 11 passes forward through the guide hole 12 and slides against the inner wall of the guide hole 12.

[0027] Therefore, as the piston rod 5 moves forward and backward, thereby driving the unblocking rod 2 to move forward and backward, the guide rod 11 moves forward and backward along the guide hole 12, thus playing a guiding role.

[0028] In this utility model, a telescopic sleeve 13 is fixedly connected between the rear end of the cylinder 3 and the front end of the housing 7. The telescopic sleeve 13 is fitted onto the rear end of the piston rod 5 to provide protection.

[0029] Therefore, as the piston rod 5 moves forward and backward, and in turn drives the unblocking rod 2 to move forward and backward, the telescopic sleeve 13 adapts to the movement of the piston rod 5.

[0030] In this utility model, the rear end of the housing 7 is provided with an outlet 14 for the wiring of the motor 1 to be led out.

[0031] In this utility model, the end of the front end of the unblocking rod 2 is fixedly connected to an auger 15.

[0032] In this utility model, both ends of the cylinder 3 are provided with air inlet / outlet ports 16, the outer ring of the piston 4 is slidably fitted with the inner wall of the cylinder 3, and the inner ring of the piston 4 is fixedly fitted to the outside of the piston rod 5 by a shrinking sleeve 17.

[0033] Therefore, air enters through the inlet / outlet port 16 at the rear end of the cylinder 3 and exits through the inlet / outlet port 16 at the front end, pushing the piston 4 forward within the cylinder 3 and causing the piston rod 5 to move forward; air enters through the inlet / outlet port 16 at the front end of the cylinder 3 and exits through the inlet / outlet port 16 at the rear end, pushing the piston 4 backward within the cylinder 3 and causing the piston rod 5 to retract.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] When it is necessary to clear the blockage of the pre-embedded pipe 18, air enters through the air inlet / outlet 16 at the rear end of the cylinder 3 and air exits through the air inlet / outlet 16 at the front end, pushing the piston 4 to move forward inside the cylinder 3, driving the piston rod 5 forward, driving the clearing rod 2 forward, pushing the auger 15 into the pre-embedded pipe 18, and moving forward along the pre-embedded pipe 18.

[0036] At this time, the piston rod 5 drives the housing 7 and the motor 1 inside it to move forward, the guide rod 11 moves forward along the guide hole 12, and the telescopic sleeve 13 is compressed.

[0037] At the same time, motor 1 drives the unblocking rod 2 and auger 15 to rotate, cleaning the dust inside the pre-embedded pipe 17 and the dust clumps on its inner wall, and sending the cleaned dust back into the kiln.

[0038] After cleaning, air enters through the inlet / outlet 16 at the front end of the cylinder 3 and exits through the inlet / outlet 16 at the rear end, pushing the piston 4 to move backward inside the cylinder 3, causing the piston rod 5 to retract, driving the unblocking rod 2 to retract, pulling the auger 15 backward along the pre-embedded pipe 18, and exiting the pre-embedded pipe 18.

[0039] At this time, the piston rod 5 drives the housing 7 and the motor 1 inside it to move backward, the guide rod 11 moves backward along the guide hole 12, and the telescopic sleeve 13 extends.

[0040] In addition, motor 1 stops, and unblocking rod 2 and auger 15 stop rotating to minimize the amount of dust carried out.

[0041] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0042] Therefore, the above are merely preferred embodiments of this application and are not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the claims of this application are within the scope of protection of the claims of this application.
