Description

Technical Field

[0001] This utility model relates to the field of auxiliary slag removal technology for high-temperature incinerators, specifically to a rapid slag removal device for high-temperature pyrolysis incinerator slag pools. Background Technology

[0002] With the increasing demand for medical waste treatment, high-temperature pyrolysis incineration technology has been widely used in the field of medical waste disposal due to its high efficiency and harmlessness. In this process, the slag formed after medical waste is dried, pyrolyzed, gasified, burned and cooled is crushed by rotating grate and moved to the slag pool at the bottom of the incinerator, and finally cleaned by the slag discharge machine. However, in actual operation, a large amount of slag, coke and entangled materials (such as iron wire) often accumulate in the slag pool, which can easily lead to malfunctions such as jamming of the slag discharge machine and chain breakage, seriously affecting the continuous and stable operation of the equipment.

[0003] Traditional slag pit cleaning methods mainly rely on manual operation. Workers need to enter the narrow and deep environment of the slag pit (up to 2.5 meters deep and only 0.65 meters wide at the bottom) to scoop out the slag-water mixture bucket by bucket. This method is not only labor-intensive and inefficient, but also poses a high risk to personal safety. At the same time, the cleaning process can easily cause environmental pollution in the workshop, with sewage flowing everywhere and sludge clogging the drainage system, further increasing the difficulty and cost of operation and maintenance. Existing equipment is difficult to meet the actual working conditions in terms of vacuum stability, corrosion resistance, and mobility, so there is room for improvement. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a rapid slag removal device for high-temperature pyrolysis incinerator slag pools.

[0005] The rapid slag removal device for high-temperature pyrolysis incinerator slag pool provided in this application adopts the following technical solution:

[0006] A rapid slag removal device for a high-temperature pyrolysis incinerator slag pool includes a storage tank, a support frame, and a sludge suction pump unit. The storage tank is fixedly installed above the support frame. A slag removal and sludge discharge port is provided on the bottom side of the storage tank for discharging slag. A sludge suction flange interface is provided on one side of the top of the storage tank. The sludge suction flange interface is connected to a sludge suction hose through a flange seal. The end of the sludge suction hose away from the storage tank is the sludge suction inlet. The sludge suction pump unit is located at the bottom of the support frame and is connected to the storage tank through a vacuum connection pipe. The sludge suction pump unit includes a vacuum pump, a motor, and a coupling. The motor is connected to the vacuum pump through the coupling to provide power to the vacuum pump and drive the vacuum pump to generate the required negative pressure. The outlet pipe of the vacuum pump is sealed to a damping tank through the vacuum connection pipe. The damping tank is used to buffer pipeline pressure fluctuations and maintain a continuous and stable vacuum pressure inside the equipment.

[0007] By adopting the above technical solution, the storage tank serves as the core for temporary storage of slag. The slag cleaning and drainage port on the side bottom facilitates the centralized discharge of slag. The suction flange interface on the top is connected to the suction hose through a flange seal, which not only ensures the airtightness of the vacuum environment to maintain the adsorption force, but also allows the suction hose to flexibly reach into various parts of the slag pool, expanding the adsorption range. In the suction pump unit, the motor provides stable power to the vacuum pump through a coupling, enabling it to generate sufficient negative pressure to meet the adsorption requirements. The damping tank connected to the vacuum pump outlet pipeline can effectively buffer pressure fluctuations, ensuring stable vacuum pressure inside the equipment and avoiding the impact of pressure changes on the adsorption effect. The bracket provides stable support for the storage tank and suction pump unit, making all components form an organic whole. The whole achieves efficient adsorption, temporary storage and discharge of slag and slag-water mixture, improving the efficiency, stability and flexibility of slag removal operations.

[0008] Optionally, the top of the storage tank is also provided with an openable and closable manhole, which is used by staff to inspect, maintain and clean the inside of the storage tank.

[0009] By adopting the above technical solution, the internal condition of the tank can be visually inspected through the manhole, allowing for timely detection and handling of problems such as scaling on the inner wall, local blockage, and residue accumulation that may occur due to long-term adsorption of slag and slag-water mixture. This avoids the impact of these hidden dangers on the effective volume of the storage tank, adsorption efficiency, and even the normal operation of the equipment due to the inability to clean them in a timely manner. This maintenance method, which allows direct contact with the inside of the tank, also makes the daily maintenance and component repair of the equipment more efficient and thorough, reducing downtime caused by equipment failure due to inconvenient maintenance and extending the service life of the storage tank and even the entire slag discharge equipment.

[0010] Optionally, an operating lever is provided above the coupling, and the operating lever is linked to the coupling to adjust the operating speed of the vacuum pump.

[0011] By adopting the above technical solution, the linkage between the operating lever and the coupling eliminates the need for complicated adjustment procedures. Operators can directly act on the coupling by manipulating the operating lever to quickly adjust the operating speed of the vacuum pump, thereby achieving precise control over the adsorption force of the equipment. This allows the equipment to flexibly cope with the complex and ever-changing working conditions in the slag pool, avoiding the problems of low adsorption efficiency or energy waste caused by a fixed rate. At the same time, it simplifies the operation process and reduces the difficulty of operation for operators.

[0012] Optionally, the inner wall of the storage tank, the inner wall of the sludge suction hose, the surface of the sludge suction pump unit that comes into contact with the slag and sludge-water mixture, and the connection interfaces of each pipeline are all coated with an anti-corrosion layer. The anti-corrosion layer is used to resist the corrosion of the slag and sludge-water mixture and to ensure the sealing performance and service life of the equipment.

[0013] By adopting the above technical solutions, the anti-corrosion layer can directly resist the erosion of the inner wall of the storage tank, the inner wall of the sludge suction hose, the contact surface of the sludge suction pump unit, and the connection interfaces of each pipeline by acidic and alkaline substances and impurities that may be contained in the slag and sludge-water mixture. This avoids problems such as damage, perforation, or sealing failure in these parts due to long-term corrosion. The anti-corrosion protection of core components greatly reduces equipment failures caused by corrosion, reduces maintenance frequency and costs, extends the overall service life of the equipment, and allows the equipment to operate stably for a long time in the complex corrosive environment of the slag and sludge-water mixture.

[0014] Optionally, the anti-corrosion layer is made of silicone anti-corrosion material and is coated on the inner wall of the storage tank, the inner wall of the suction pipe, the surface of the suction pump unit that comes into contact with the sludge-water mixture, and all connection interfaces through a special anti-corrosion process.

[0015] By adopting the above technical solutions, the organosilicon anti-corrosion material itself has excellent chemical corrosion resistance, water resistance and aging resistance. It can specifically resist the corrosion of equipment surface by acid and alkali components, impurities and other substances that may be contained in the slag-water mixture. The special coating process ensures that the anti-corrosion layer is tightly bonded to the inner wall of the storage tank, the inner wall of the suction pipe, the surface of the suction pump unit in contact with the medium and various connection interfaces, forming a continuous, uniform and dense protective film, avoiding local corrosion problems caused by poor coating adhesion and uneven coverage.

[0016] Optionally, the bracket is equipped with swivel casters at the four corners of its bottom, and the swivel casters have a locking function.

[0017] By adopting the above technical solution and installing omnidirectional casters with locking functions at the four corners of the bottom of the support, the mobility and operational stability of the entire slag removal equipment are greatly improved. According to the slag removal needs of different areas in the slag pool, the staff can easily push the equipment to move flexibly in multiple directions and angles within the work site, quickly adjust the adsorption position of the sludge suction inlet, effectively cover all corners of the slag pool, and avoid blind spots in slag removal caused by equipment fixation. The locking function of the omnidirectional casters ensures that after the equipment reaches the designated working position, the locking mechanism can be operated to fix the casters, preventing the equipment from shifting due to vibration or external force during negative pressure adsorption operation, and ensuring the stability of the equipment during operation.

[0018] Optionally, a control device is also included, which is installed on one side of the bracket and adjusts the operating status of the coupling through circuitry to indirectly control the start, stop, and speed of the vacuum pump in the sewage suction pump unit.

[0019] By adopting the above technical solution, a control device is installed on one side of the bracket to indirectly control the vacuum pump by regulating the operating status of the coupling through circuit. The installation position of the control device is convenient for operators to observe and operate at any time. It transmits control commands to the coupling through circuit, which can realize a rapid response to start and stop of the vacuum pump.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. Through the synergistic effect of the suction pump unit and the damping tank, efficient and stable adsorption and transportation of slag and slag-water mixture are achieved, which greatly improves the slag discharge efficiency.

[0022] 2. The use of an organosilicon anti-corrosion layer to fully cover key components significantly enhances the equipment's durability in corrosive environments and extends its service life;

[0023] 3. By using technologies such as vacuum pumps, storage tanks, and control devices, the sludge and residue in the incinerator ash pit can be quickly and completely removed, restoring the incinerator to normal and safe operation. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses a rapid slag removal device for high-temperature pyrolysis incineration slag pools.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A rapid slag removal device for high-temperature pyrolysis incineration slag pools uses a frame-type support 3 as the overall load-bearing foundation. The universal casters 5 installed at the four corners of the bottom of the support 3 can drive the equipment to move flexibly. After reaching the designated working position, the equipment is fixedly positioned by the locking function of the casters to prevent displacement during operation.

[0031] The storage tank 2, fixedly installed above the support 3, is made of Q235 carbon steel. It measures 1.6 meters long, 1.45 meters wide, and 1.05 meters high, with a thickness of approximately 6 millimeters and a volume of 2 cubic meters, sufficient for temporary storage during a single slag removal. A 220mm slag discharge port 20 is located on the bottom side of the storage tank 2 for centralized discharge of temporarily stored slag. A DN100mm suction flange interface 21 is welded to one side of the top of the storage tank 2, which is sealed to a 10-meter-long suction hose 22 via the flange and sealing gasket. The end of the suction hose 22 furthest from the storage tank 2 is the suction inlet. Utilizing the flexibility of the suction hose 22, this inlet can easily reach into every corner of the slag pool, expanding the suction range. The top of the storage tank 2 also features an openable and closable manhole 23, allowing staff to inspect, maintain, and clean the interior of the tank, promptly addressing issues such as scaling and blockages on the inner wall.

[0032] A sludge suction pump unit 1 is installed at the bottom of the support frame 3. The sludge suction pump unit 1 includes a vacuum pump 10, a motor 11, and a coupling 12. The motor 11 is connected to the vacuum pump 10 through the coupling 12, providing stable power for the operation of the vacuum pump 10 and generating a negative pressure greater than 0.09MPa. The vacuum pump 10 is sealed and connected to the storage tank 2 through a vacuum connection pipe 14, forming a complete adsorption channel. An operating rod 13 is installed above the coupling 12, and the two are linked. The operator can directly adjust the operating speed of the vacuum pump 10 by operating the operating rod 13. A control device 6 is also installed on one side of the support frame 3. It controls the operating status of the coupling 12 through circuit, and indirectly realizes precise control of the start and stop and speed of the vacuum pump 10. It can flexibly adjust parameters according to the slag accumulation and slag water concentration in the slag pool.

[0033] The outlet pipe of the vacuum pump 10 is sealed to a damping tank 4 via a vacuum connection pipe 14, which effectively buffers pressure fluctuations in the pipe and maintains a stable vacuum pressure inside the equipment, ensuring the adsorption effect. At the same time, the inner wall of the storage tank 2, the inner wall of the sludge suction hose 22, the surface of the sludge suction pump unit 1 that comes into contact with slag and sludge-water mixture, and the connection interfaces of each pipe are all coated with an anti-corrosion layer using an organosilicon anti-corrosion material through a special process, which can resist the corrosion of acid and alkali substances in the sludge-water mixture, ensuring the sealing performance and service life of the equipment.

[0034] Before operating the equipment, check the sealing of all connections to ensure reliable vacuum connection. Push the equipment to the slag pool, lock the casters 5, align the suction inlet of the suction hose 22 with the slag accumulation area, and start the control device 6. The motor 11 drives the vacuum pump 10 through the coupling 12. The negative pressure generated by the vacuum pump 10 is transmitted to the storage tank 2 and the suction hose 22 through the vacuum connection pipe 14. Under the action of negative pressure, the suction inlet draws the slag and slag-water mixture into the suction hose 22, and then enters the storage tank 2 for temporary storage through the suction flange interface 21. During operation, the speed of the vacuum pump 10 can be adjusted by the operating lever 13. The damping tank 4 buffers pressure fluctuations in real time to ensure stable adsorption. When the storage tank 2 is close to full or after slag removal is completed, turn off the motor 11 and the vacuum pump 10, open the slag removal and drainage port 20 to discharge the slag, and complete one slag removal operation.

[0035] The implementation principle of the rapid slag removal device for high-temperature pyrolysis incinerator slag pool in this application embodiment is as follows:

[0036] The motor 11 drives the vacuum pump 10 through the coupling 12 to generate negative pressure, which forms a closed adsorption passage through the vacuum connection pipe 14. The slag and slag-water mixture in the slag pool is sucked into the storage tank 2 through the sludge suction hose 22 for temporary storage. The damping tank 4 maintains the vacuum pressure in real time. The control device 6 and the operating lever 13 work together to adjust the equipment operation status to adapt to different working conditions. The anti-corrosion layer provides durable protection for the core components. The temporarily stored slag is finally discharged through the slag cleaning and sewage discharge port 20, forming an efficient cycle of "adsorption-temporary storage-sludge discharge". This quickly solves the jamming problem of traditional slag discharge machines, shortens the sludge cleaning time, and reduces the frequency of equipment failure and maintenance.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
