Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] like figure 1 As shown, a low-temperature crystallization product online sampling device, such as image 3 , Figure 4 As shown, the sampling device consists of two parts: a fixed component and a detachable component; Figure 5As shown, the fixed components include: sub-joint 1, full-bore ball valve 2, sub-joint 2 3, quick-open joint sub-head 4; detachable components include: quick-open joint female head 5, sleeve 6, soft sealing packing 7. Gland 8, sampling rod 9, fixing bolt 10, gasket 11, nipple three 12, sampling valve 13, sampling pipe 14. The fixing component is fixed to the pipeline to be sampled by welding through the short joint one 1, and the other end of the short joint one 1 is welded to the full-bore ball valve 2, the short joint two 3, and the quick-opening sub-joint 4 in sequence. In the detachable assembly, the quick-opening female joint 5 an...

Abstract

The invention discloses an online sampling device for low-temperature crystallized products. The device comprises a fixed assembly and a detachable assembly. The fixing assembly is composed of a full-bore ball valve, a short section and a quick-opening sub-connector, the fixing assembly is fixed to a to-be-sampled pipeline through the short section in a welding mode, and the other end of the short section is sequentially connected with the full-bore ball valve, the short section and the quick-opening sub-connector in a welded mode; the detachable assembly is composed of a sealing gasket, a quick-opening female joint, a sleeve, a soft sealing filler, a soft sealing gland, a short section, a sampling pipe and a sampling rod, the quick-opening female joint in the detachable assembly is detachably fixed with one end of the sleeve through a pipe thread, the other end of the sleeve is provided with a stepped reducing part, and the soft sealing filler is arranged at the stepped reducing part; and the axial displacement of the soft sealing filler is limited through the soft sealing gland, and the soft sealing gland is fixed with the sleeve through a bolt. The device realizes on-line sampling of low-temperature solid crystallization products and solid-liquid mixtures, and solves the problem of low repeated utilization rate of existing sampling.

Description

technical field [0001] The invention belongs to the fields of refinery, food and medicine, and relates to a sampling device, in particular to an online sampling device for low-temperature crystallization products. Background technique [0002] In the petrochemical industry, in order to ensure product quality and monitor product process indicators, it is necessary to set up a number of sampling points in chemical equipment, through the analysis and inspection of regular sampling samples, so as to ensure product quality and guide production. Since most of these devices operate continuously, the design of online sampling devices is critical. However, the existing online sampling technology is mostly suitable for fluid media such as gaseous and liquid states, and is not suitable for online sampling of slurry or semi-solid media such as solid crystallization products and solid-liquid mixtures in low temperature environments, and the existing technology is mostly a sampling One p...
