Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a sliding sampler of an online laser particle size analyzer. Background Art

[0002] When using a laser particle size analyzer to measure the particle size distribution of a particle sample, the sample being measured must be diluted to an appropriate concentration (expressed as the shading ratio). In-line laser particle size analyzers require that particle samples be removed from the production line and properly dispersed and diluted before measurement. Therefore, an automatic sampling device is a key component in an in-line laser particle size measurement system. Wet grinding is one of the two major categories of powder (slurry) production, and sampling methods typically include gravity flow or pumping. However, the slurry viscosity on some grinding lines (such as sand mills) is very high, making it difficult to reliably and quantitatively extract samples from the production line using the aforementioned two methods. Utility Model Content

[0003] The utility model aims to provide a sliding sampler for an online laser particle size analyzer, which can solve the problem of difficulty in taking out samples stably and quantitatively when sampling from a grinding production line due to the high viscosity of the slurry.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A sliding sampler for an online laser particle size analyzer comprises a production line feed pipe and a barrel mounted on the pipe. A sliding rod is mounted within the barrel, with a sampling chamber located at its lower end. The lower end of the sliding rod extends into the production line feed pipe, allowing the sampling chamber to be immersed in the feed liquid in the production line feed pipe. A lifting device is mounted on the top of the barrel, with its bottom connected to the upper end of the sliding rod, driving the sliding rod in an up-and-down motion.

[0006] Preferably, a dilution channel is provided at the bottom of the barrel, with a dilution liquid inlet and a dilution liquid outlet at either end. The dilution liquid inlet is connected to a dilution liquid tube for inputting the dilution liquid into the dilution channel; the dilution liquid outlet is connected to a dilution liquid tube for discharging the dilution liquid from the dilution channel. When the lifting device drives the sliding rod upward, the sampling cavity is pulled into the dilution channel, and the liquid in the sampling cavity is diluted in the dilution channel.

[0007] Preferably, the sampling cavity is a through hole or groove structure.

[0008] Preferably, the lifting device is a reciprocating cylinder.

[0009] Preferably, a valve is provided on the diluent tube to control the flow of liquid in the diluent tube.

[0010] The utility model obtains liquid through the sampling cavity at the lower end of the sliding rod. This sampling method can also normally sample slurries with high viscosity on the production line, and the sampling amount can be determined reliably. By changing the volume of the sampling cavity, the sampling amount can be easily changed. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0016] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand the advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. Example 1

[0017] The present invention obtains the liquid through the sampling cavity 8 at the lower end of the sliding rod 7. This sampling method can also normally sample the slurry with high viscosity on the production line, and the sampling amount can be determined reliably. By changing the volume of the sampling cavity 8, the sampling amount can be easily changed.

[0018] like Figure 1As shown, a sliding sampler for an online laser particle size analyzer includes a production line feed pipe 9 and a barrel 10 mounted on the production line feed pipe 9. A sliding rod 7 is mounted within the barrel 10, and a sampling cavity 8 is provided at the lower end of the sliding rod 7. The lower end of the sliding rod 7 extends into the production line feed pipe 9, allowing the sampling cavity 8 to be immersed in the feed liquid in the production line feed pipe 9. A lifting device 3 is mounted on the top of the barrel 10. The bottom of the lifting device 3 is connected to the upper end of the sliding rod 7, driving the sliding rod 7 to move back and forth.

[0019] Furthermore, a dilution channel 11 is provided at the bottom of the barrel 10, with a dilution liquid inlet 4 and a dilution liquid outlet 2 at either end. The dilution liquid inlet 4 is connected to a dilution liquid tube 5 for inputting dilution liquid into the dilution channel 11; the dilution liquid outlet 2 is connected to a dilution liquid tube 1 for discharging the dilution liquid from the dilution channel 11. When the lifting device 3 drives the sliding rod 7 upward, the sampling chamber 8 is pulled into the dilution channel 11, where the liquid in the sampling chamber 8 is diluted.

[0020] The dilution channel 11 can be combined with the sampling method to quickly dilute the feed liquid. At the same time, the valve 6 described below can also control the volume of the dilution liquid, thereby controlling the dilution multiple.

[0021] Furthermore, the sampling cavity 8 is a through hole or groove structure. It should be noted that the diameter of the dilution channel 11 is larger than the diameter of the sampling cavity 8 .

[0022] Furthermore, the pulling device 3 is a reciprocating cylinder.

[0023] Furthermore, a valve 6 is provided on the diluent tube 5 to control the flow of liquid in the diluent tube 5 .

[0024] Working principle:

[0025] like Figure 1-2 As shown, the barrel 10 is mounted on the production line material pipe 9. The core components of this sliding sampler are the sliding rod 7 and the sampling cavity 8 provided at the lower end of the sliding rod 7. The sampling cavity 8 can move up and down along with the sliding rod 7 driven by the pulling device 3.

[0026] Figure 1 The sampling cavity 8 is located at the bottom and is completely immersed in the liquid in the production line material pipe 9. The liquid flows from right to left (or in the opposite direction) in the production line material pipe 9, so the sampling cavity 8 will soon be filled with liquid. Figure 2During the process, the lifting device 3 drives the sampling chamber 8, raising it so that its left and right ends are connected to the dilution liquid outlet 2 and dilution liquid inlet 4, respectively. Valve 6 is then opened, allowing dilution liquid to flow from the dilution liquid pipe 5 into the sampling chamber 8, diluting the feed liquid and forming a dilution liquid. This liquid then flows out of the dilution liquid outlet 2 and along the dilution liquid pipe 1 to the particle size measurement unit. The dilution liquid is allowed to flow for a period of time to flush out particles from the sampling chamber 8 and the subsequent pipelines. When needed, the sampling chamber 8 is lowered again for the next sampling.

[0027] In the description of the present invention, it should be understood that the terms "middle", "length", "upper", "lower", "front", "back", "vertical", "horizontal", "inner", "outer", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the present invention, unless otherwise expressly specified or limited, a first feature "on" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. "Multiple" means at least two, such as two or three, unless otherwise expressly specified or limited.

[0029] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
