Description

Technical Field

[0001] This utility model relates to the field of fluid feeding equipment technology, specifically a feeding device for fluid sampling and analysis. Background Technology

[0002] Fluid feeding devices are used to transport liquids, slurries, colloids and other fluid materials from storage containers to processing equipment or other designated locations. They are widely used in many industries such as chemical, food, pharmaceutical and beverage.

[0003] Fluid feeding devices mainly utilize the power generated by a power source to overcome the resistance of the fluid and transport the fluid from one location to another. Rotary pumps are one type of fluid feeding device. However, existing fluid feeding devices do not have a convenient sampling structure for operation, making it difficult to conveniently sample and analyze the fluid during use, which is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for fluid sampling and analysis, in order to solve the problem that existing fluid feeding devices do not have a convenient sampling structure, making it difficult to perform fluid sampling and analysis.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for fluid sampling and analysis, comprising: a feeding rotor pump, wherein a sampling tee is fixedly provided at one end of the feeding rotor pump, and a sampling connecting pipe is provided at one end of the sampling tee below.

[0006] As a further embodiment of this utility model: the feeding rotor pump includes a fixed mounting base, a drive servo motor is fixedly installed at one end of the fixed mounting base, a rotor pump body is fixedly installed at the other end of the fixed mounting base, an inlet flange pipe is fixedly connected to one side of the rotor pump body, and an outlet flange pipe is fixedly connected to the other side of the rotor pump body.

[0007] As a further embodiment of this utility model: the sampling tee includes a sampling tee body, and a tee thick-walled tube is fixedly connected to one end of the sampling tee body. A U-shaped adjusting groove is provided on one end of the inner side of the tee thick-walled tube.

[0008] As a further embodiment of this utility model: a three-way inlet flange pipe is fixedly connected to one side of the sampling three-way seat, and a three-way outlet flange pipe is fixedly connected to the other side of the sampling three-way seat; and three sets of U-shaped adjusting grooves are provided.

[0009] As a further embodiment of this utility model: the sampling connecting tube includes a movable sampling tube, a rotating hexagonal seat is fixedly provided at one lower end of the movable sampling tube, an externally threaded connecting tube is fixedly provided at one lower end of the rotating hexagonal seat, and a sampling inlet through hole is provided at one upper outer side of the movable sampling tube. The movable sampling tube, the rotating hexagonal seat, the externally threaded connecting tube and the sampling inlet through hole are interconnected, and three sets of sampling inlet through holes are provided.

[0010] As a further embodiment of this utility model: an upper sealing ring is embedded inside the outer side of the movable sampling tube above the sampling inlet hole, a lower sealing ring is embedded inside the outer side of the movable sampling tube below the sampling inlet hole, and a fan-shaped adjusting slider is fixedly installed at one end of the outer side of the movable sampling tube below the lower sealing ring, and the number of fan-shaped adjusting sliders is set to three.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a sampling bottle or sampling pipeline is connected via an externally threaded connecting pipe. Then, by rotating the hexagonal seat, the sampling connecting pipe is rotated, causing the fan-shaped adjusting slider to move from the lower convex groove of the U-shaped adjusting groove to the longitudinal groove. At this time, the sampling connecting pipe can be pushed upward until the fan-shaped adjusting slider is in contact with the upper part of the U-shaped adjusting groove. Then, the sampling connecting pipe is rotated so that the fan-shaped adjusting slider is embedded in the upper convex groove of the U-shaped adjusting groove for a limit. At this time, the sampling inlet hole and the upper sealing ring are pushed into the sampling tee body, while the lower sealing ring is still located in the tee thick-walled pipe to achieve a seal. Fluid can enter the movable sampling tube through the sampling inlet hole and be discharged through the externally threaded connecting pipe for sampling. This enables the fluid sampling work to be carried out quickly and conveniently. Attached Figure Description
