The blockage of slag not only leads to a decrease in the boiler operation efficiency but also increases the maintenance cost. More seriously, when the slag discharge port is blocked, it is usually necessary for the staff to manually dredge it, which not only increases the additional labor cost but also poses a great safety hazard when operating in a high-temperature environment. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a simple boiler slag discharging device to solve the problems in the above background art.

[0012] 1. Through the lifting and rotation of the inserting rod, the conically arranged spiral blades can more easily insert into the slag, accelerating the moving speed of the slag, thus significantly improving the slag discharge efficiency.

[0013] 2. An automated control system is adopted. The insertion rod is rotated by a motor, and the sliding plate is controlled by a pushing mechanism to drive the insertion rod to move up and down, greatly reducing the need for manual dredging and lowering the labor cost. There is no need for manual dredging of the blocked slag discharge port, reducing the operation risk in a high-temperature environment and improving the safety of operators.

[0014] 3. The design is simple, easy to maintain and repair, reducing the maintenance frequency and cost caused by slag discharge port blockage.

[0020] As Figures 1 - 2 shown, a simple boiler slag discharge device includes a flap valve 2 installed at the boiler slag discharge port 1. A shunt cylinder 4 is provided below the flap valve 2, and a connecting cylinder 3 is fixedly arranged between the shunt cylinder 4 and the flap valve 2. An insertion rod 5 that moves up and down and rotates is arranged in the shunt cylinder 4, and the insertion rod 5 is coaxially arranged with the connecting cylinder 3;

[0021] A pointed head 502 is fixedly arranged at the end of the insertion rod 5, and a spiral blade 501 is fixedly arranged on the outside. The pointed head 502 and the spiral blade 501 move into the boiler slag discharge port 1 and rotate to accelerate slag discharge. Opening the flap valve 2 enables the slag in the boiler slag discharge port 1 to enter the shunt cylinder 4 from the connecting cylinder 3 and be discharged. The insertion rod 5 in the shunt cylinder 4 can rotate and insert into the boiler slag discharge port 1, and the spiral blade 501 can accelerate the slag feeding at the boiler slag discharge port 1.

[0022] The boiler slag discharge port 1 is the outlet for discharging slag. The slide gate valve 2 is installed on the slag discharge port and controls the slag discharge by opening or closing. The slide gate valve can move horizontally to cover or expose the slag discharge port.

[0023] The connecting cylinder 3 is located below the slide gate valve and is fixedly connected thereto. Its function is to connect the slide gate valve and the shunt cylinder to form a continuous passage for the slag to pass through. The insertion rod 5 is arranged inside the shunt cylinder and can perform lifting and rotating actions. The end of the insertion rod is equipped with a pointed head 502, and a spiral blade 501 is installed on the outside. When the insertion rod rotates, the pointed head can insert into the slag, and the spiral blade helps to push the slag downward.

[0024] The pointed head 502 and the spiral blade 501 can help the insertion rod better insert into the slag, and the spiral blade can push the slag along the direction of the slag discharge port when the insertion rod rotates, thus accelerating the slag discharge process.

[0025] The working principle is as follows:

[0026] When slag discharge is required, the operator opens the slide gate valve 2 so that the slag can flow out from the boiler slag discharge port 1. The insertion rod 5 can make its pointed head 502 enter the slag discharge port 1, and the spiral blade 501 pushes the slag downward as the insertion rod rotates, and enters the shunt cylinder 4 through the connecting cylinder 3. In the shunt cylinder 4, the slag continues to move downward and is finally discharged.

[0027] Preferably, the spiral blade 501 is fixed on the insertion rod 5 in a conical shape from top to bottom. The conical arrangement of the spiral blade 501 enables it to more conveniently enter the coal slag.

[0028] The front end of the cone is sharper, which helps to reduce the resistance when inserting into the coal slag, making the insertion rod 5 easier to penetrate a harder or denser coal slag layer. The conical design can ensure that the spiral blade always maintains a good contact area with the coal slag during the insertion process, thus effectively pushing the coal slag downward. Since the front end is thinner, the possibility of encountering obstacles during insertion is reduced, and the risk of jamming is reduced. Lower insertion resistance means less energy is required to drive the insertion rod, which helps to save energy. The conical design allows the insertion rod 5 to more easily adapt to coal slag with different densities and humidities, thus improving the flexibility of the overall system. The conical front end reduces the contact area with the coal slag, which helps to reduce the wear of the spiral blade.

[0029] When the insertion rod 5 rotates and moves upward, the conically arranged spiral blades 501 will gradually insert into the cinder. As the insertion rod rotates, the spiral blades push the cinder to move along the direction of the slag discharge port 1. Since the spiral blades are conical and thinner at the front end, they can more easily penetrate the cinder and can be smoothly inserted even when encountering a harder cinder layer. The pointed tip 502 of the insertion rod 5 can help further guide the cinder to flow downward, and at the same time, the conical structure of the spiral blades 501 can effectively push the material through the connecting cylinder 3 into the diversion cylinder 4.

[0030] Preferably, discharge cylinders are provided on both sides of the diversion cylinder 4. The insertion rod 5 is arranged in the fixing seat 6 between the discharge cylinders on both sides. A seal is provided in the fixing seat 6, and the seal abuts against the insertion rod 5. The insertion rod 5 slides and rotates in the fixing seat 6 by abutting against the seal, ensuring its sealing performance.

[0031] Discharge cylinders are provided on both sides of the diversion cylinder 4. The function of these discharge cylinders is to further guide the treated slag to the outside for the collection and treatment of the slag. The insertion rod 5 is arranged in the fixing seat 6 between the discharge cylinders on both sides. The insertion rod 5 is located in the fixing seat 6, and the fixing seat is located between the two discharge cylinders. The insertion rod can freely move up and down and rotate in the fixing seat. Seals are installed inside the fixing seat 6 to prevent the leakage of slag or other substances and ensure good sealing performance when the insertion rod 5 is moving. The seals are in direct contact with the insertion rod 5 to ensure good sealing effect even during the up and down movement and rotation of the insertion rod, preventing the leakage of slag or flue gas. The insertion rod 5 can slide and rotate in the fixing seat 6, and at the same time, through the close cooperation of the seals, the sealing performance during its movement is ensured.

[0032] Preferably, a sliding plate 7 is provided below the diversion cylinder 4. Fixed plates 9 are fixedly provided on both sides of the diversion cylinder 4. The fixed plates 9 are connected to the sliding plate 7 through a pushing mechanism 10. Both ends of the sliding plate 7 are connected to the fixed plates 9 through the pushing mechanism 10, so as to be able to drive the sliding plate 7 to drive the insertion rod 5 to move up and down.

[0033] The sliding plate 7 is located below the diversion cylinder 4 and can slide in the vertical direction. Its function is to drive the insertion rod 5 to move up and down by moving up and down. The fixed plates 9 are fixed on both sides of the diversion cylinder 4 as the fixed support of the pushing mechanism 10. The pushing mechanism 10 is connected between the fixed plates 9 and the sliding plate 7. Through the action of the pushing mechanism 10, the up and down movement of the sliding plate 7 can be realized. The pushing mechanism 10 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod, etc.

[0034] Both ends of the sliding plate 7 are connected to the fixed plates 9 through the pushing mechanism 10. The telescopic movement of the pushing mechanism 10 can drive the sliding plate 7 to move up and down. When the sliding plate 7 moves up and down, it will drive the insertion rod 5 in the fixing seat 6 to move together, thereby realizing the lifting of the insertion rod 5.

[0035] When it is necessary to start the slag discharging process, the operator controls the pushing mechanism 10 to move the sliding plate 7 upward. The upward movement of the sliding plate 7 drives the insertion rod 5 in the fixed seat 6 to rise. At this time, the pointed end 502 and the spiral blade 501 of the insertion rod 5 can be inserted into the slag. Next, the insertion rod 5 can be rotated by the driving device, and the spiral blade 501 will push the slag downward and enter the diversion cylinder 4 through the connecting cylinder 3. After the insertion rod 5 completes the slag discharging task, the operator controls the pushing mechanism 10 again to lower the sliding plate 7, and the insertion rod 5 will also descend, preparing for the next operation.

[0036] Preferably, a motor 8 is fixedly installed in the middle of the sliding plate 7, and the output shaft of the motor 8 is fixedly connected to the end of the insertion rod 5.

[0037] The motor 8 is installed at the middle position of the sliding plate 7, and its function is to provide power to drive the insertion rod 5 to rotate. The output shaft of the motor 8 is fixedly connected to one end of the insertion rod 5. In this way, when the motor is started, the rotation of the output shaft will be directly transmitted to the insertion rod 5, causing the insertion rod 5 to rotate.

[0038] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
