Nitrogen blowing concentrator rotation-adjusting blowing beam device

Abstract

The invention discloses a nitrogen blowing concentrator rotation-adjusting blowing beam device and belongs to the field of a nitrogen blowing concentrator supporting device. The blowing beam device comprises a left-right adjusting assembly, a front-rear adjusting assembly and a blowing assembly. The two ends of the left-right adjusting assembly are mounted on the inner side of a cover plate of a nitrogen blowing concentrator or on a frame body above the nitrogen blowing concentrator main body; and the front-rear adjusting assembly and the blowing assembly are mounted on the left-right adjusting assembly. The blowing beam device is ingenious in overall design; a blowing needle can realize rotation adjusting in the axial direction; a locking bolt and a knob can ensure the blowing beam deviceto be moved and adjusted on the inner side of the cover plate of the nitrogen blowing concentrator or on the frame body above the nitrogen blowing concentrator main body to ensure that nitrogen blownout of a port of the blowing needle can blow the liquid mixture to be concentrated or purified in a container to form a vortex in the container, thereby facilitating fast concentration or purification of the liquid mixture; and the device is good in overall sealing performance and has no air leakage cases.

Description

technical field [0001] The invention relates to the field of an air blowing beam device for a nitrogen blowing concentrator, in particular to a nitrogen blowing concentrator to rotate and adjust an air blowing beam device. Background technique [0002] In the process of many research tests such as detection test research, material composition analysis research, material composition research and trace element analysis research, it is usually necessary to concentrate or purify some component liquid mixtures to meet the actual requirements of different analysis experiments. When concentrating or purifying related liquid mixtures, it is sometimes necessary to use a nitrogen blowing concentrator. When using the nitrogen blowing concentrator for experimental research, it is often necessary to match the blowing beam device with the container containing the liquid mixture to be concentrated or purified, so as to ensure the normal progress of the research experiment using the nitroge...

AI Technical Summary

Problems solved by technology

The following problems exist in the actual use of the ordinary blowing beam device of the nitrogen blowing concentrator: 1. In order to be able to adjust the blowing needle on the ordinary blowing beam device, it is usually at the part where the blowing needle is connected to the main pipe of the blowing beam device. The soft connection or soft material is used to make the blowing needle. In actual use, the soft connection is easy to be damaged. The actual need for accurate positioning of the air needle port; 2. The ordinary air blowing beam device has no main adjustment pipe, secondary adjustment pipe and supporting ring holder, and the air blowing needle cannot be rotated to adjust, and the air blowing beam device cannot be placed on the top of the nitrogen blowing concentrator. The inner side of the plate, or the upper frame of the main body of the nitrogen blowing concentrator, cannot ensure that the port of the blowing needle maintains the best matching angle and the best matching distance with the port of the container containing the liquid mixture to be concentrated or purified. The nitrogen gas blown out from the port of the blowing needle can blow the liquid mixture to be concentrated or purified in the container, forming a vortex in the container, which is beneficial to the rapid concentration or purification of the liquid mixture; Air leakage is prone to occur at the part where the main pipe of the blowing beam device is connected, as well as the part where the main pipe of the blowing beam device is connected to the blowing needle
