Abstract
Description
Technical Field
[0001] This application relates to the field of slag sampling technology, specifically a slag sampling device for waste-to-energy boilers. Background Technology
[0002] In the process of generating electricity using waste-to-energy boilers, slag sampling devices are required to sample the slag. While existing slag sampling devices for waste-to-energy boilers can meet the basic requirements for slag sampling, some slag often remains on the outer wall of the sampling structure during the sampling process. However, these devices often lack a residue cleaning structure to remove this residue. Consequently, when users move the sampling structure to the outside of the boiler, the slag residue on the outer wall of the sampling structure spills, causing environmental pollution and significant inconvenience to users.
[0003] The authorization announcement number CN222419537U discloses a slag sampling device for waste-to-energy boilers. The device loosens the limiting bolts and releases the fixation of the connection between the connecting cylinder and the connecting rod, and then moves the connecting rod and the cleaning collar away from the handle, so that the cleaning collar scrapes over the outer wall of the sampling tank, thereby scraping and cleaning the slag remaining on the outer wall of the sampling tank.
[0004] However, the connecting rod is inserted into the connecting cylinder and fixed by the limiting bolt. When the cleaning collar is needed, it may take some time to loosen and tighten the limiting bolt. In addition, during the operation, it may be necessary to hold the connecting cylinder with one hand and operate the limiting bolt with the other hand. In the complex environment around the waste-to-energy boiler, the operation is not convenient and efficient.
[0005] Based on this, a slag sampling device for waste-to-energy boilers is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.
[0031] Example 1:
[0032] In one embodiment, such as Figures 1-5 As shown, the slag sampling device for waste-to-energy boilers in this embodiment includes a fixed handle 1 and a sampling rod 2. The front end of the sampling rod 2 is fixedly connected to the rear end of the fixed handle 1, and a sampling groove 3 is provided at the rear end of the sampling rod 2. A sliding handle 4 is sleeved on the surface of the sampling rod 2, and a locking block 5 is fixedly installed on the inner side wall of the sliding handle 4. A groove adapted to the locking block 5 is opened on the periphery of the sampling rod 2. The matching of the locking block 5 and the outer groove of the sampling rod 2 allows the sliding handle 4 to slide along the axis of the sampling rod 2, improving the stability of cleaning. An installation groove adapted to the front side of the sliding handle 4 is opened at the rear end of the fixed handle 1. An installation bolt 7 is fixedly installed in the sampling groove 3. The sampling rod 2 is provided with a threaded hole adapted to the installation bolt 7 (not shown in the figure). An adjusting block 6 is provided on the installation bolt 7. The adjusting block 6 is used to adjust the length of the installation bolt 7 entering the threaded hole to adjust the orientation of the sampling groove 3. A limit component is provided on the inner side of the fixed handle 1, and cleaning components are provided on the left and right sides of the sliding handle 4.
[0033] In this embodiment, the fixed handle 1 is fixedly connected to the front end of the sampling rod 2, providing a gripping base for the operator. The mounting bolt 7 is fixed at the center of the front side of the sampling slot 3 and threadedly connected to the adjusting block 6, thereby installing the sampling slot 3 and the sampling rod 2 together. The sampling slot 3 is used to collect slag samples. The sliding handle 4 is sleeved on the surface of the sampling rod 2 and can slide along the sampling rod 2. The locking block 5 cooperates with the groove on the periphery of the sampling rod 2 to restrict the sliding path of the sliding handle 4 on the sampling rod 2. The mounting groove at the rear end of the fixed handle 1 is adapted to the front side of the sliding handle 4. The sliding handle 4 is embedded in the mounting groove and is limited by the limiting component. When cleaning the sampling slot 3, the limiting component releases the limitation on the sliding handle 4, so that it can only move along a specific trajectory, thereby making the cleaning component more precise in cleaning the sampling slot 3.
[0034] In one embodiment, such as Figure 1 and Figure 5 As shown, the sampling rod 2 has a storage hole at the rear end for the installation bolt 7 to pass through, and the fixed handle 1 and the sliding handle 4 have anti-slip grooves on their surfaces to increase the stability of the sampling device for the staff.
[0035] In one embodiment, such as Figure 2 As shown, the limiting component includes a fixed plate 8, which is fixedly connected to the inner wall of the fixed handle 1. Two sliding rods 9 are provided through the inner side of the fixed plate 8 and are fixedly connected to it. Sliding blocks 10 are slidably connected to the surface of the sliding rods 9 and at the top and bottom of the fixed plate 8. A positioning rod 11 is fixedly installed on the side of the sliding block 10 away from the fixed plate 8. A sliding sleeve 12 is sleeved on the surface of the front sliding rod 9. The side of the sliding sleeve 12 away from the fixed plate 8 passes through the inner side of the fixed handle 1 and is fixedly installed with a pressing block 13. The limiting component can slide the sliding handle 4 into the inner side of the mounting groove to position and fix it, preventing the sliding handle 4 from accidentally sliding during the sampling process and affecting the stability of operation. The extension and retraction of the positioning rod 11 is controlled by the pressing block 13, making the operation simple and convenient.
[0036] In one embodiment, such as Figure 2 As shown, springs 14 are provided at the top and bottom of the fixed plate 8 and on the surface of the sliding rod 9 to drive the sliding block 10 to slide outward. Lifting grooves 15 are provided at the rear end of the fixed handle 1 where it is connected to the sampling rod 2, allowing the sliding block 10 to slide up and down. When the pressing block 13 is pressed, the sliding sleeve 12 is moved towards the fixed plate 8, compressing the spring 14. The sliding block 10 and the positioning rod 11 then move inward. The positioning rod 11 falls out of the positioning hole 16, thereby releasing the positioning of the sliding handle 4.
[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, the inner side of the sliding handle 4 is provided with a positioning hole 16 that is compatible with the positioning rod 11, and the inner side of the sampling rod 2 is provided with a connecting hole through which the positioning rod 11 can pass. Under the action of the spring 14, the positioning rod 11 passes through the connecting hole and is inserted into the inner side of the positioning hole 16 to achieve positioning of the sliding handle 4.
[0038] In one embodiment, such as Figure 3 and Figure 4As shown, the cleaning assembly includes a cleaning sleeve 17. Connecting rods 18 are fixedly installed on the front side of the cleaning sleeve 17 near the left and right sides. Connecting blocks are fixedly installed at the front ends of the connecting rods 18. Fixing brackets 19 are fixedly installed on the left and right sides of the sliding handle 4. A threaded rod 20 is threaded through the inner side of the fixing bracket 19 and is threadedly connected to it. A limiting block 21 is fixedly installed at the end of the threaded rod 20 near the sampling rod 2. When the cleaning sleeve 17 needs to be installed, the connecting block is inserted into the installation port of the sliding handle 4, and then the threaded rod 20 is rotated so that the limiting block 21 is engaged in the limiting groove 22 of the connecting block, thus fixing the cleaning sleeve 17.
[0039] In one embodiment, such as Figure 3 and Figure 4 As shown, the sliding handle 4 has mounting openings on both the left and right sides that are compatible with the connecting block. The connecting block has a limiting groove 22 on the side away from the sliding handle 4 that is compatible with the limiting block 21. The top and bottom of the limiting block 21 are slidably connected to the inner wall of the fixing frame 19. The cleaning sleeve 17 is fixed by the cooperation of the threaded rod 20 and the limiting block 21. The installation is firm and easy to adjust, which improves the practicality and maintenance convenience of the device.
[0040] In one embodiment, such as Figure 3 and Figure 4 As shown, the cleaning sleeve 17 has a cleaning port on its inner side that is compatible with the sampling tank 3, so that the slag remaining on the outer wall of the sampling tank 3 can be scraped and cleaned through the cleaning port.
[0041] Example 2:
[0042] Please see Figure 6 To facilitate material collection, the sampling groove 3 is provided with a pointed structure at its end, which helps the sampling groove 3 to collect samples smoothly.
[0043] Example 3:
[0044] Please see Figure 7 In order to match the cleaning sleeve 17 with the sampling groove 3, the outer side of the sampling rod 2 is symmetrically provided with guide rings 23. The guide rings 23 are slidably arranged with the sampling rod 2, which can guide the cleaning sleeve 17 to be stably connected with the sampling groove 3 and avoid interference during cleaning.
[0045] The above embodiment discloses a slag sampling device for waste-to-energy boilers, wherein the fixed handle 1 is fixedly connected to the front end of the sampling rod 2 to form the main gripping part of the device, and the sampling slot 3 is threadedly connected to the adjusting block 6 rotatably connected to the rear end of the sampling rod 2 through the mounting bolt 7 at the center of its front side, thus completing the installation of the sampling slot 3. The sliding handle 4 is fitted onto the surface of the sampling rod 2. The inner wall of the handle 4 engages with the groove around the sampling rod 2 to limit the sliding path. The cleaning sleeve 17 is installed through the connecting rod 18 and the connecting block, and is engaged with the threaded rod 20 and the limiting block 21 on the left and right fixed brackets 19 of the sliding handle 4. The operator holds the fixed handle 1 and takes a sample through the sampling slot 3. After the sample is taken, the operator presses the pressing block 13 on the inner side of the fixed handle 1, which moves the sliding sleeve 12 toward the fixed plate 8 and compresses the spring 14, causing the sliding block 10 and the positioning rod 11 to move inward. The positioning rod 11 disengages from the positioning hole 16, releasing the positioning of the sliding handle 4. At this time, the sliding handle 4 can move along a specific trajectory. During the movement, the cleaning port on the inner side of the cleaning sleeve 17, which is adapted to the sampling slot 3, scrapes and cleans the slag remaining on the outer wall of the sampling slot 3. After cleaning, the operator presses the pressing block 13 again, and the device returns to its initial state for the next use.
[0046] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
