Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of medical intermediate production equipment, especially relates to a medical high purity hydrogen chloride organic solution closed sampling device. BACKGROUND
[0002] Hydrogen chloride organic solution is widely used in pharmaceutical industry, can be used for acetal reaction protection aldehyde group, also can be used for anhydrous acid reaction. Since the product index requirement of medical intermediate is extremely high, and hydrogen chloride organic solution is extremely volatile, so the sampling and detection analysis of the product are required higher.
[0003] At present, the enterprise that the product is mass-produced in the domestic is few, does not have perfect hydrogen chloride organic solution product system, and most enterprises production device is relatively simple, and there is no closed sampling device, and the open sampling causes the on-site environment to be bad, seriously affects the health of post personnel. UTILITY MODEL CONTENT
[0004] In view of the above technical problem, the utility model provides a medical high purity hydrogen chloride organic solution closed sampling device.
[0005] In order to realize the above purpose, the technical scheme of the utility model is as follows:
[0006] A medical high purity hydrogen chloride organic solution closed sampling device, comprising:
[0007] Integrated closed sampler, the import end is connected with the material conveying pipeline on the outlet end of the hydrogen chloride organic solution circulating tank of the high purity hydrogen chloride organic solution production system through the closed sampling front hand valve, and the export end is connected with the material conveying pipeline on the outlet end of the hydrogen chloride organic solution circulating pump of the high purity hydrogen chloride organic solution production system through the closed sampling rear hand valve.
[0008] The utility model has the advantages that: the utility model adds a kind of closed sampling device on the basis of the original high purity hydrogen chloride organic solution production device, replaces the extensive operation of open sampling in the guide of the hydrogen chloride organic solution circulating pump previously. BRIEF DESCRIPTION OF DRAWINGS
[0009] The utility model is further illustrated as follows in combination with drawings and embodiments:
[0010] Figure 1 It is the principle diagram of the utility model; DETAILED DESCRIPTION
[0011] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.
[0012] like Figure 1 As shown, a closed sampling device for medical high-purity hydrogen chloride organic solution includes: an integrated closed sampler 4, the inlet end of which is connected to the feed pipe on the outlet end of the hydrogen chloride organic solution circulation tank 1 of the high-purity hydrogen chloride organic solution production system through a closed sampling front hand valve 3, and the outlet end is connected to the feed pipe on the outlet end of the hydrogen chloride organic solution circulation pump 2 of the high-purity hydrogen chloride organic solution production system through a closed sampling rear hand valve 5.
[0013] The present invention connects the bottom of a hydrogen chloride organic solution circulation tank 1 to a hydrogen chloride organic solution circulation pump 2, which is then connected to the top liquid inlet of a falling film absorber 6. The lower liquid outlet of the falling film absorber 6 is connected to the top of the hydrogen chloride organic solution circulation tank 1. The aforementioned device is part of an existing production system for producing high-purity medical hydrogen chloride organic solution. The present invention adds a closed sampling device to the existing device. A new pipeline is added between the hydrogen chloride organic solution circulation tank 1 and the hydrogen chloride organic solution circulation pump 2, and a closed sampling front hand valve 3 is installed. A new pipeline is added before the reflux line of the hydrogen chloride organic solution circulation pump 2 outlet line, and a closed sampling rear hand valve 5 is installed. These two newly added pipelines are connected, and an integrated closed sampler 4 is installed between the closed sampling front hand valve 3 and the closed sampling rear hand valve 5.
[0014] During operation: the valve of the integrated closed sampler 4 itself is similar to a tee, and can be regarded as a pipeline connecting device when closed. In the production process of medical high-purity hydrogen chloride organic solution, except for sampling at the specified time, the closed sampling front hand valve 3, the integrated closed sampler 4 and the closed sampling rear hand valve 5 are kept closed. When sampling at the specified time in the production process of medical high-purity hydrogen chloride organic solution, the closed sampling rear hand valve 5 and the closed sampling front hand valve 3 are opened one by one. After circulating for 1-3 minutes, the integrated closed sampler 4 is opened. When the liquid level in the sampling bottle reaches 2 / 3, the integrated closed sampler 4, the closed sampling front hand valve 3 and the closed sampling rear hand valve 5 are closed one by one.
[0015] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all changes and modifications falling within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
