Technical Field

[0001] The utility model relates to the technical field of chemical metallurgy, in particular to a high-efficiency slaked lime sampling device. Background Art

[0002] High-efficiency slaked lime, primarily composed of calcium hydroxide, is an important inorganic substance. It typically appears as a white or slightly yellowish fine powder and can be effectively used in environmental protection applications. High-efficiency slaked lime is typically transported in tank trucks. Traditionally, high-efficiency slaked lime sampling is performed manually, requiring personnel to open the tank truck's hatch and reach into the interior with a sampling cup to scoop out a sample. Conventional sampling only captures the surface material, which is not very representative. Furthermore, manual sampling inevitably involves contact with the high-efficiency slaked lime and requires working at height, posing significant safety risks. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the utility model discloses an efficient slaked lime sampling device, the sampling device 100 includes a sampling tube 2, an air-powder separation device 5 and a sample collecting bucket 7, one end of the sampling tube 2 is fixedly connected to the ash unloading pipeline 1, the sampling tube 2 is connected to the ash inlet valve 3 and the ash outlet valve 4, the front end of the sampling tube 2 is connected to the ash unloading pipeline 1 through a sampling head, which can meet the needs of fixed-point and interval sampling of slaked lime in the ash unloading pipeline 1, and can achieve isolation of sampling personnel and materials to ensure the safety of the sampling process. Taking portion samples at fixed intervals during the unloading process can also effectively ensure the representativeness of the sample.

[0024] like Figures 1 and 2 As shown, the air inlet end of the gas-powder separation device 5 is fixedly connected to the other end of the sampling tube 2; the gas-powder separation device 5 includes a cylinder 51 and a cylinder cover 52 fixedly connected to the cylinder 51 by a quick-connect assembly 54. The top of the cylinder cover 52 is provided with an exhaust port 53. The lower end of the cylinder 51 is provided with a conical discharge bin 55 and an ash discharge valve 56 connected to the outlet of the conical discharge bin 55. The sample collecting bucket 7 is correspondingly arranged below the conical discharge bin 55. During operation, positive pressure is generated during the discharge process of the discharge channel, and then the powder is pumped into the sampling tube. The ash discharge pipeline 1 is sampled through the sampling tube 2. The powder sample enters the gas-powder separation device 2 through the sampling tube to achieve gas-material separation. The slaked lime powder sample enters the conical discharge bin for storage under the action of its own gravity, and is discharged into the sample collecting bucket through the ash discharge valve for testing. The gas-powder separation device is mainly used to relieve pressure and separate the high-efficiency slaked lime in the compressed air, so that the sample can enter the sample collecting bucket smoothly.

[0025] In a preferred embodiment, if Figure 2 As shown, a filter screen plate 57 is correspondingly provided at the connection between the cylinder body 51 and the cylinder cover 52. The filter screen plate can filter the gas powder sample so that the slaked lime powder falls into the conical lower hopper.

[0026] In a preferred embodiment, if Figure 3As shown, the quick-connect assembly 54 includes a ferrule 541 with two disconnected ends, a locking block 542 and a locking seat 544, respectively disposed at each end of the ferrule 541. The locking block 542 is centrally provided with a locking slot 543 with an open front end. The front end of the locking seat 544 is hingedly connected to a locking handle 548 via a first pivot 545.

A locking rod 5410 and a locking cap 5411 fixed to the front end of the locking rod 5410 are connected to the sidewall of the sleeve 549. The locking handle 548 rotates via the first pivot 545, driving the locking rod 5410 to either a locked position or a disconnected position. A retaining slot 547 is provided on the rear sidewall of the locking seat 544 for engagement with the second pivot 546. During operation, the locking handle is rotated toward the side of the locking block through the first pivot, and the locking cap of the locking rod is correspondingly engaged in the locking groove. Then the locking handle is rotated away from the locking block through the first pivot to tighten the locking rod, and the second pivot is correspondingly engaged in the limiting groove, thereby locking the quick-connect assembly.

[0027] In a preferred embodiment, the hoop 541 has flange structures protruding inward at the upper and lower ends of the ring wall. The flange structure of the hoop can be correspondingly clamped on the connecting flanges of the cylinder body and the cylinder cover, thereby achieving a sealed and fixed connection between the cylinder body and the cylinder cover.

[0028] The ash inlet valve 3, ash outlet valve 4 and ash discharge valve 56 are manual valves or automatic valves. More preferably, the ash inlet valve 3, ash outlet valve 4 and ash discharge valve 56 are automatic valves to meet the requirements of sample collection and sample quantity control for controlling high-efficiency slaked lime.

[0029] like Figure 4 As shown, the sampling device 100 also includes a support frame 6 corresponding to the gas-powder separation device 5. The support frame 6 includes a frame 61 and a conical seat 62 arranged at the top of the frame 61. A support position groove 63 for the conical discharge bin 55 to be clamped is provided in the conical seat 62.

[0030] It should be noted that the sampling device 100 also includes a control system that uses existing technology to realize its functions. The control system is electrically connected to the ash inlet valve 3, the ash outlet valve 4, the ash unloading valve 56 and the negative pressure fan, thereby realizing the automatic operation of the slaked lime sampling device. Portion samples can be taken at fixed intervals during the unloading process. The sampling interval is entered into the sampling device before sampling. When unloading, automatic sampling begins when the time reaches the set sampling interval. This cycle continues until the unloading of the entire vehicle of high-efficiency slaked lime is completed.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
