Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, and particularly relates to a sampling device for the preparation of p-nitrobenzoic acid. Background Art

[0002] P-nitrobenzoic acid is a strong oxidant and can undergo oxidation reactions with many substances. Under the action of p-nitrobenzoic acid, many organic substances can be oxidized to corresponding aldehydes, ketones or carboxylic acids. In addition, it also has biological activities such as antibacterial, antiviral and anti-inflammatory. Therefore, p-nitrobenzoic acid has important application values in the pharmaceutical field. Besides being used as a pharmaceutical intermediate, p-nitrobenzoic acid can also be used to prepare other drugs and chemicals. At the same time, p-nitrobenzoic acid also has important industrial application values, such as playing an important role in the synthesis of spices, dyes, explosives, etc.

[0003] When implementing this technical solution, there are at least the following defects: when the existing p-nitrobenzoic acid is detected, a sampling cylinder is usually used to sample the powder of p-nitrobenzoic acid. However, it is inconvenient to seal the lower end of the sampling cylinder during the sampling process, resulting in the situation that the powder of p-nitrobenzoic acid drops. Moreover, since the sampling cylinder is inserted into the storage appliance of p-nitrobenzoic acid, the p-nitrobenzoic acid powder is stored in the sampling cylinder under extrusion, resulting in very unsmooth discharge, and improvement is urgently needed. Therefore, we propose a sampling device for the preparation of p-nitrobenzoic acid. Summary of the Utility Model

[0006] By adopting the above technical solutions, the spring can drive the baffle to reset, and the slide bar on the baffle can move along the direction of the chute, thereby closing the left end of the sampling cylinder, avoiding the situation of p-nitrobenzoic acid powder falling during the process of moving the sampling cylinder, and at the same time, it can also push the sleeve to move leftward, driving the dredging rod on the fixed frame to move accordingly, so that the iron ring on the dredging rod can push the p-nitrobenzoic acid powder in the sampling cylinder, facilitating the sampling and discharging of the p-nitrobenzoic acid powder.

[0007] Optionally, the size of the slide bar is adapted to the size of the chute, and the slide bar is slidably connected to the chute.

[0009] Optionally, the other side of the baffle is in contact with one side of the fixed ring, and the baffle is symmetrically arranged.

[0010] By adopting the above technical solutions, through the setting of the baffle, the through port of the fixed ring can be blocked.

[0011] Optionally, the inner cavity radius of the fixed ring is the same as the inner cavity radius of the sampling cylinder.

[0012] By adopting the above technical solutions, it is convenient for the p-nitrobenzoic acid powder in the sampling cylinder to be discharged.

[0013] Optionally, a return spring is fixedly installed in the inner cavity of the chute, and the other end of the return spring is fixedly connected to the slide bar.

[0017] Compared with the prior art, the beneficial effects of the technical solutions of the present application are as follows:

[0018] The technical solution of this application, through the sampling cylinder, fixed ring, return spring, towing rope, sleeve and dredging rod set, can not only make the spring drive the baffle to reset, make the sliding rod on the baffle move along the chute direction, and then can seal the left end of the sampling cylinder, thus avoiding the situation of p-nitrobenzoic acid powder falling during the process of moving the sampling cylinder, but also can push the sleeve to move leftward, make the sleeve drive the dredging rod on the fixed frame to move along, and then make the iron ring on the dredging rod push the p-nitrobenzoic acid powder in the sampling cylinder, thus facilitating the sampling and discharging of the p-nitrobenzoic acid powder.
