[0003] Therefore, in actual production, it is necessary to sample and detect the sludge discharged from the sludge dewatering equipment; for the existing centrifugal sludge dewatering machine, considering factors such as plant floor area during installation and layout, the sludge dewatering machine is often installed on the building floor slab, and its discharged sludge drops into the sludge bin below the building floor slab through the sludge discharge channel, while the sampling operation is carried out through the observation and sampling port arranged above the detection floor slab; in the previous sampling operation, the operator holds a trough-shaped sampler for sampling. On the one hand, under the impact force of the falling sludge, the sampler is prone to situations such as the fracture of the welding part, and the fractured sampler drops into the sludge bin below, affecting the operation safety of the subsequent equipment; on the other hand, after the operator extracts the sample, a shovel or directly grabs the sludge by hand into the sampling bag, which is not only inefficient but also unsafe and unhygienic, bringing inconvenience to use.

[0004] Therefore, a sampling device that is stable in use and can effectively avoid the operator from grabbing the sludge by hand and improve the sampling efficiency is a problem that needs to be solved currently. Summary of the Utility Model

[0007] Further, a front baffle is arranged at the front end of the sampling groove part.

[0008] Further, the diameter of the scraping plate is the same as the inner diameter of the cylinder part.

[0009] Further, a discharge port is arranged below the cylinder part.

[0010] Furthermore, a first support plate and a second support plate are sequentially arranged behind the discharge opening of the cylindrical body part, and the pull rod sequentially slides through the first support plate and the second support plate.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0026] Embodiment of the present invention:

[0027] As Figure 2-5 shown, in the sampling device 4 of this embodiment, a sampling cylinder 41 is provided. The sampling cylinder 41 includes a cylinder part 411 at the rear end and a sampling groove part 412 with a horizontal slot at the front end above. A front baffle 414 is provided at the front end of the sampling groove part 412, a discharge port 413 is provided below the cylinder part 411, and a first support plate 415 and a second support plate 416 are sequentially provided behind the discharge port 413.

[0028] A mud scraping device 42 is slidably connected through the first support plate 415 and the second support plate 416. Among them, a mud scraping plate 421 is provided in the mud scraping device 42. The diameter of the mud scraping plate 421 is the same as the inner diameter of the sampling cylinder 41. The mud scraping plate 421 is fixedly welded to the front end of the pull rod 422. The rear side of the pull rod 422 sequentially passes through the first support plate 415 and the second support plate 416 and is slidably connected with the first support plate 415 and the second support plate 416. The rear end of the pull rod 422 is connected to the handrail 423.

[0029] The lower part outside the rear end of the sampling cylinder 41 is connected to the roller device 43. Among them, a connecting plate 431 is provided in the roller device 43. First connecting rods 432 are respectively welded on both sides of the connecting plate 431, and the two sides of the first connecting rods 432 are fixedly connected to both sides of the sampling cylinder 41 by welding; a second connecting rod 433 is welded below the connecting plate 431, and a mounting plate 434 is welded through the second connecting rod 433. There are two mounting plates 434 and they are symmetrically arranged on both sides below the connecting plate 431. Universal wheels 435 are rotatably installed through the mounting plates 434.

[0030] The principle of the present utility model is as follows:

[0031] As Figure 1 shown, when the present utility model is in use, sampling is carried out through the observation and sampling port 13 on the sludge discharge channel 1 of the existing sludge dewatering machine. The sludge dewatering machine involved in the present utility model is a centrifugal sludge dewatering machine, etc. During actual installation, it is generally installed vertically. The sludge dewatering machine is installed above the building floor slab 2, and its discharged sludge enters the sludge discharge channel 1 through the sludge inlet 11, and then falls into the sludge bin 3 below the building floor slab 2 through the sludge outlet 12, thereby achieving the saving of the factory building space.

[0032] The present utility model is arranged based on the existing observation and sampling port 13 on the sludge discharge channel 1. During sampling, the observation window (existing, not shown in the attached drawings of the specification) on the observation and sampling port 13 is opened, and at this time, the sampling device 4 of the present utility model is pushed and inserted into the observation and sampling port 13.

[0033] During the sampling process, the scraping plate 421 is located at the front baffle 414, and the sludge dehydrated by the sludge dewatering machine falls from top to bottom into the sampling tank part 412 to complete the sampling. After sampling, the sampling device 4 is pulled out, and then the scraping plate 421 is pulled, and the collected sample can be discharged through the discharge port 413, thereby completing the sampling process. There is no need to grab with hands during the process, which is cleaner and more hygienic; after sampling, the sampling device 4 is cleaned and placed on one side, and then the observation window on the observation and sampling port 13 is closed.

[0034] The whole of the present utility model is made of stainless steel, and each component can be fixedly connected by welding or other means, which is more firm and durable; in addition, for the connecting plate 431, a thicker plate can be used to ensure the weight at the rear of the whole device, playing a role in counterweight, so as to ensure the balance and stability of the device during the moving process.
