Description

Technical Field

[0001] This utility model relates to the field of sampling mechanism technology, specifically a sampling mechanism for phase analysis of sintered fly ash from waste incineration. Background Technology

[0002] Fly ash primarily originates from the incineration of municipal solid waste. During incineration, organic matter in the waste is mainly emitted as gaseous substances, while inorganic matter mainly forms solid particulate matter. Fly ash sintered body is a solid material obtained by mixing fly ash with other additives, granulating the mixture, and sintering it at a temperature below the melting point of the mixture. Because fly ash sintered body has high compressive strength and density, and heavy metals are effectively fixed, it can be used in the production of building materials such as ceramics, lightweight aggregates, and concrete. Before applying the sintered body, it is necessary to take samples for phase analysis to understand its relevant properties, facilitating subsequent processing and utilization.

[0003] When sampling sintered bodies, a shovel is usually used to scoop up the sample and place it into a sample container. Since the shovel is in direct contact with the sintered body, some sintered body will inevitably adhere to it. When scooping up other batches of sintered bodies, some sintered body from the previous batch will be mixed into the sample being scooped up. Moreover, the sample itself is relatively small in volume, so the residue on the shovel may have a significant impact on the analysis results. In addition, during the process of scooping up and moving the sample, some sintered body particles may be scattered, causing pollution to the sampling environment. Therefore, in order to address the above problems, a sampling mechanism for phase analysis of sintered bodies of waste incineration fly ash is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a sampling mechanism for phase analysis of sintered fly ash from waste incineration. This sampling mechanism moves an automatic reset cylinder frame via a sampling rod, thereby inserting a sampling cylinder mounted on the automatic reset cylinder frame into the sintered body to complete the sampling. After sampling, the sampling cylinder can be directly removed and replaced with a new one to complete the next sampling. This sampling method does not cause contamination between samples, thus improving the accuracy of the analysis results. In addition, this sampling method is less likely to cause the sintered body to scatter. After sampling, the automatic reset cylinder frame can be swung back and forth by pulling a rope to shake off the sample adhering to the outer wall of the sampling cylinder, ensuring that the sintered body does not scatter outside. This solves the technical problems of sample contamination and sample scattering that easily contaminate the sampling environment during sampling in the prior art.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A sampling mechanism for phase analysis of sintered fly ash from waste incineration includes a fork frame with an automatic reset cylinder frame rotatably connected to its fork, and a sampling rod and a sampling cylinder fixedly connected to its end. The sampling cylinder is inserted into the automatic reset cylinder frame for sampling. The sampling cylinder is inserted into the sintered body by operating the sampling rod to complete the sampling. After sampling, the sampling cylinder can be directly removed and replaced with a new sampling cylinder to complete the next sampling. This sampling method does not cause contamination between samples and can improve the accuracy of the analysis results. In addition, a pulling mechanism is provided to pull the automatic reset cylinder frame to rotate. The pulling mechanism includes a connecting lug fixedly installed on the automatic reset cylinder frame and a lead wire block fixedly installed on the sampling rod. A pull rope is connected to the connecting lug, and the end of the pull rope passes through the lead wire block. After sampling, the automatic reset cylinder frame can be swung back and forth by pulling the pull rope to shake off the sample attached to the outer wall of the sampling cylinder, ensuring that the sintered body is not scattered outside.

[0007] In one possible implementation, the fork includes a U-shaped rod with hinged rings fixedly installed at both ends. The automatic reset cylinder includes two hoop rings, which are fixedly connected by a connecting plate. A capped rotating shaft is fixedly connected to the connecting plate, wherein the capped rotating shaft passes through the hinged rings and is rotatably connected to them. The above structure can realize the rotatable connection between the automatic reset cylinder and the fork, providing the necessary structural basis for the automatic reset cylinder to drive the sampling cylinder to swing.

[0008] In one possible implementation, the capped shaft consists of a shaft body and an end cap fixedly connected to the end. A reset torsion spring is sleeved on the shaft body. The two ends of the reset torsion spring are fixedly connected to the end cap and the hinge ring, respectively. When the automatic reset cylinder is pulled and rotated, the reset torsion spring will accumulate elastic potential energy. When the automatic reset cylinder is not under tension, the reset torsion spring will release elastic potential energy and drive the automatic reset cylinder to rotate and reset.

[0009] In one possible implementation, an L-shaped abutment is fixedly provided on the end cap of the capped shaft, and limit baffles are fixedly provided on both sides of the U-shaped rod. When the automatic reset cylinder rotates to a horizontal state, the L-shaped abutment and the limit baffles fit tightly together. The cooperation between the L-shaped abutment and the limit baffles can limit the maximum angle of rotation of the automatic reset cylinder during the automatic reset process. That is, when the automatic reset cylinder is not under tension, it will remain horizontal under the limiting action of the L-shaped abutment and the limit baffles.

[0010] In one possible implementation, the sampling tube includes a tube body, and a tube cap is provided at the opening of the tube body. The outer diameter of the tube body matches the inner diameter of the hoop. After sampling is completed, the tube cap is placed on the back of the tube body to complete the sample encapsulation.

[0011] In one possible implementation, the cylinder cover is provided with a slot, the size of which matches the opening size of the cylinder body. This snap-fit ​​method can support the inner wall of the opening of the cylinder body, preventing the cylinder cover from falling off due to pressure deformation at the opening of the cylinder body during transportation.

[0012] In one possible implementation, the lead block has a groove with a diameter larger than that of the pull rope along its length. The groove openings at both ends are beveled. This structure can constrain the pull rope and prevent it from tangling. The pull rope end is fixedly connected to a pull ring with a size larger than that of the groove. The pull ring structure can prevent the pull rope end from coming off the lead block.

[0013] In one possible implementation, an end connecting plate is fixedly provided on the hoop, and a magnetic suction plate is fixedly provided in the middle of the hoop. An iron sheet is attached to the corresponding position at the bottom of the sampling tube. The magnetic suction plate can attract and fix the end of the sampling tube, thereby improving the anti-slip ability of the sampling tube.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] The sampling mechanism moves the automatic reset cylinder frame by operating the sampling rod, and then operates the sampling cylinder installed on the automatic reset cylinder frame to insert into the sintered body to complete the sampling. After the sampling is completed, the sampling cylinder can be directly removed and replaced with a new sampling cylinder to complete the next sampling. This sampling method will not cause mixing and contamination between samples and can improve the accuracy of the analysis results.

[0016] In addition, this sampling method directly completes the sample loading work with the sample container, which will not cause the sintered body to scatter during the process of moving and loading into the container. After the sampling is completed, the automatic reset cylinder can be swung back and forth by pulling the rope to shake off the sample attached to the outer wall of the sampling cylinder, ensuring that the sintered body will not scatter outside.

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 , Figure 2 , Figure 5 As shown in the figure, this embodiment provides a sampling mechanism for phase analysis of sintered fly ash from waste incineration. It includes a fork frame 1, with an automatic reset cylinder frame 2 rotatably connected to its fork, and a sampling rod 4 fixedly connected to its end. A sampling cylinder 3 is inserted into the automatic reset cylinder frame 2 for sampling. Sampling is completed by inserting the sampling cylinder 3 into the sintered body using the sampling rod 4. After sampling, the sampling cylinder 3 can be directly removed and replaced with a new one to complete the next sampling. This sampling method avoids mixing and contamination between samples and can... To improve the accuracy of the analysis results, a pulling mechanism 5 is also provided, which is used to pull the automatic reset cylinder 2 to rotate. The pulling mechanism 5 includes a connecting ear 51 fixedly mounted on the automatic reset cylinder 2 and a lead block 52 fixedly mounted on the sampling rod 4. A pull rope 53 is connected to the connecting ear 51, and the end of the pull rope 53 passes through the lead block 52. After sampling, the automatic reset cylinder 2 can be pulled back and forth by the pull rope 53 to shake off the sample attached to the outer wall of the sampling cylinder 3, ensuring that the sintered body will not be scattered outside.

[0026] like Figure 2 — Figure 3 As shown, the fork frame 1 includes a U-shaped rod 11, with hinge rings 12 fixedly installed at both ends of the U-shaped rod 11. The automatic reset cylinder frame 2 includes two hoop rings 21, which are fixedly connected by a connecting plate 22. A capped rotating shaft 23 is fixedly connected to the connecting plate 22. The capped rotating shaft 23 passes through the hinge ring 12 and is rotatably connected to it. The above structure can realize the rotatable connection between the automatic reset cylinder frame 2 and the fork frame 1, providing the necessary structural basis for the automatic reset cylinder frame 2 to drive the sampling cylinder 3 to swing.

[0027] The capped rotating shaft 23 consists of a shaft body and an end cap fixedly connected to the end. A reset torsion spring 24 is provided on the outer sleeve of the shaft body. The two ends of the reset torsion spring 24 are fixedly connected to the end cap and the hinge ring 12, respectively. When the automatic reset cylinder 2 is pulled and rotated, the reset torsion spring 24 will accumulate elastic potential energy. When the automatic reset cylinder 2 is not under tension, the reset torsion spring 24 will release elastic potential energy and drive the automatic reset cylinder 2 to rotate and reset.

[0028] To prevent the automatic reset cylinder 2 from rotating excessively during the reset process of the reset torsion spring 24 and affecting normal use, an L-shaped abutment plate 25 is fixedly installed on the end cap of the capped rotating shaft 23, and limit baffles 13 are fixedly installed on both sides of the U-shaped rod 11. When the automatic reset cylinder 2 rotates to a horizontal state, the L-shaped abutment plate 25 and the limit baffles 13 fit tightly together. The cooperation between the L-shaped abutment plate 25 and the limit baffles 13 can limit the maximum angle of rotation of the automatic reset cylinder 2 during the automatic reset process. That is, when the automatic reset cylinder 2 is not under tension, it will remain horizontal under the limiting action of the L-shaped abutment plate 25 and the limit baffles 13.

[0029] like Figure 4 As shown, the sampling cylinder 3 includes a cylinder body 31, and a cylinder cover 32 is provided at the opening of the cylinder body 31. The outer diameter of the cylinder body 31 matches the inner diameter of the hoop 21. After sampling is completed, the cylinder cover 32 is added to the cylinder body 31 to complete the sample sealing. The cylinder cover 32 has a slot 33, the size of which matches the opening size of the cylinder body 31. This snap-fit ​​method can support the inner wall of the opening of the cylinder body 31 and prevent the cylinder cover 32 from falling off due to pressure deformation at the opening of the cylinder body 31 during transportation.

[0030] like Figure 5 As shown, a groove 54 with a diameter larger than that of the pull rope 53 is provided in the middle of the lead block 52 along its length. The groove openings at both ends of the groove 54 are beveled. This structure can constrain the pull rope 53 and prevent it from tangling. A pull ring with a size larger than that of the groove 54 is fixedly connected to the end of the pull rope 53. The pull ring structure can prevent the end of the pull rope 53 from coming out of the lead block 52.

[0031] like Figure 4 As shown, an end connecting plate 26 is fixedly installed on the hoop 21, and a magnetic suction plate 27 is fixedly installed in the middle. An iron sheet is attached to the corresponding position at the bottom of the sampling cylinder 3. The magnetic suction plate 27 can adsorb and fix the end of the sampling cylinder 3, thereby improving the anti-slip ability of the sampling cylinder 3.

[0032] The working principle and usage process of this utility model:

[0033] The sampling mechanism moves the automatic reset cylinder frame 2 by operating the sampling rod 4, and then operates the sampling cylinder 3 installed on the automatic reset cylinder frame 2 to insert into the sintered body to complete the sampling. After the sampling is completed, the sampling cylinder 3 can be directly removed and replaced with a new sampling cylinder 3 to complete the next sampling. This sampling method will not cause mixing and contamination between samples and can improve the accuracy of the analysis results. Among them, the hoop 21 is fixedly provided with an end connecting plate 26, and a magnetic suction plate 27 is fixedly provided in the middle. The corresponding position of the bottom of the sampling cylinder 3 is attached with an iron plate, which can use the magnetic suction plate 27 to adsorb and fix the end of the sampling cylinder 3, thereby improving the anti-slip ability of the sampling cylinder 3.

[0034] In addition, this sampling method directly completes the sample loading work with the sample container, which will not cause the sintered body to scatter during the process of moving and loading into the container. After the sampling is completed, the automatic reset cylinder frame 2 can be pulled back and forth by the pull rope 53 to shake off the sample attached to the outer wall of the sampling cylinder 3, ensuring that the sintered body will not scatter outside.

[0035] During the aforementioned swinging process, when the automatic reset cylinder 2 is pulled and rotated, the reset torsion spring 24 will accumulate elastic potential energy. When the automatic reset cylinder 2 is not under tension, the reset torsion spring 24 will release elastic potential energy, driving the automatic reset cylinder 2 to rotate and reset. Furthermore, the cooperation between the L-shaped abutment 25 and the limiting baffle 13 can limit the maximum angle of rotation of the automatic reset cylinder 2 during the automatic reset process. That is, when the automatic reset cylinder 2 is not under tension, it will remain horizontal under the limiting action of the L-shaped abutment 25 and the limiting baffle 13.

[0036] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
