Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Referring to Figures 1 to 6 As shown, this embodiment provides a high-solid-content reaction liquid sampler with a self-cleaning function, including a cylinder body 1. One end of the cylinder body 1 is an open structure, and the other end of the cylinder body 1 is slidably connected with a piston rod 3. The end of the piston rod 3 located inside the cylinder body 1 is fixedly connected with a piston 302. One end of the piston 302 away from the piston rod 3 is fixedly connected with a conical piston 303. The conical piston 303 is an elastic structure. The open end of the cylinder body 1 is detachably connected with a conical housing 102. A secondary extrusion structure is provided between the inner wall of the conical housing 102 and the outer wall of the conical piston 303. An expansion part is provided inside the conical piston 303. The expansion part cooperates with the secondary extrusion structure to extrude the residual sample inside the sampler. The expansion part is communicated with a gas supply structure.

[0030] The piston 302 is driven by the piston rod 3 to drive the conical piston 303 to move, realizing sampling. When the sample is extruded, the piston rod 3 is pushed to drive the piston 302 and the conical piston 303 to extrude the sample. Then, the air supply structure supplies air to the expansion part. The expansion part expands, pushing the conical piston 303 to deform and discharging the sample remaining between the conical piston 303 and the conical shell 102, reducing the sample residue.

[0031] In addition, by providing a detachable conical shell 102, the conical shell 102 can be removed after sampling is completed, facilitating cleaning and avoiding the contamination of secondary sampling.

[0032] In a further optimized solution, the secondary extrusion structure includes a plurality of first convex ribs 103 fixedly connected to the inner wall of the conical shell 102. The plurality of first convex ribs 103 are arranged at equal intervals along the circumferential direction of the conical shell 102, and the length direction of the first convex ribs 103 is arranged from the large end to the small end of the conical shell 102.

[0033] A plurality of second convex ribs 305 are fixedly connected to the outer side wall of the conical piston 303. The plurality of second convex ribs 305 are arranged at equal intervals along the circumferential direction of the conical piston 303, and the length direction of the second convex ribs 305 is arranged from the large end to the small end of the conical piston 303. The interval between the second convex ribs 305 corresponds to the interval between two first convex ribs 103.

[0034] In a further optimized solution, the side wall of the second convex rib 305 close to the large end of the conical piston 303 is in close fit with the first convex rib 103, and a gap is reserved between the side wall of the second convex rib 305 close to the small end of the conical piston 303 and the first convex rib 103.

[0035] In a further optimized solution, the expansion part includes an airbag cavity 304 opened inside the conical piston 303. The airbag cavity 304 extends into the second convex rib 305, and the airbag cavity 304 is communicated with a gas channel 301. The gas channel 301 is opened inside the piston rod 3 and the piston 302.

[0036] Connect the gas channel 301 to an air compressor. When there is still some residue in the sampler after the high-solid-content liquid is extruded, at this time, the gas is introduced into the gas channel 301. The airbag cavity 304 will expand, pushing the conical piston 303 to expand outward, and also pushing the second convex rib 305 to expand outward. At this time, the sample remaining between the second convex rib 305 and the first convex rib 103 is extruded for the second time, reducing the sample residue in the sampler.

[0037] In a further optimized solution, a stepped hole is opened in the inner wall of one end of the conical shell 102 close to the cylinder body 1, and a step is provided on the outer wall of one end of the cylinder body 1 close to the conical shell 102. The stepped hole and the step are detachably matched by threads, and the inner walls of the cylinder body 1 and the conical shell 102 are adapted to each other.

[0038] A detachable connection is provided between the conical shell 102 and the cylinder 1, which facilitates the removal of the conical shell 102 for cleaning and avoids the contamination of the second sampling.

[0039] In a further optimized solution, a material inlet / outlet 101 is provided at the small end of the conical shell 102.

[0040] In a further optimized solution, a handle 2 is provided at the end of the piston rod 3 located outside the cylinder 1.

[0041] In a further optimized solution, the length of the piston rod 3 is greater than the length of the cylinder 1.

[0042] By setting the length of the piston rod 3 to be greater than the length of the cylinder 1, after the conical shell 102 is removed, the piston rod 3 can be further pushed to expose the piston 302 and the conical piston 303 outside the cylinder 1, which facilitates the cleaning of the piston 302 and the conical piston 303.

Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
