Description

Technical Field

[0001] This utility model relates to the field of conveying technology, specifically to a cooling conveying device for piperazine compounds. Background Technology

[0002] Piperazine compounds are a class of compounds containing a piperazine structure in their structure. These compounds are important pharmaceutical intermediates, mainly used in the production of anthelmintic drugs such as piperazine phosphate and piperazine citrate, as well as fluphenazine, diphenhydramine, and rifampin. They are also used in the production of surfactants such as wetting agents, emulsifiers, and dispersants, and in the production of plastic processing aids and rubber additives such as antioxidants, preservatives, and stabilizers. Piperazine is also known as hexahydropyrazine or diethylenediamine. When precipitated from ethanol, it is a white, orthorhombic, foliated crystal with a mild amine odor, a salty taste, and hygroscopic properties.

[0003] A Chinese patent with patent number CN219889973U describes a cooling and conveying device for piperazine compounds. The device includes a housing, a stirring mechanism, and a conveying mechanism. An electric valve is installed at the connection between the conveying mechanism and the housing. The housing wall is hollow, with an inlet and an outlet on the outer wall. Symmetrical connectors are located at the same horizontal level on the inner wall. Nuts are threadedly installed at each connector, and star-shaped connecting pipes are threadedly installed between the nuts at the same horizontal level. This invention, by using nuts and star-shaped connecting pipes, connects the star-shaped connecting pipes to the inner connectors of the housing. This allows the stirring mechanism to maximize the contact area of ​​the material within the housing, enabling rapid, thorough, and uniform cooling by the cooling water.

[0004] However, the aforementioned patent uses a flange connection when replacing and installing the fabric cover. Therefore, during installation, one worker needs to hold the flange ring on the fabric cover and align it with the flange ring on the lower delivery pipe, while another worker uses bolts to fix the two flange rings. This requires two workers to work together, which is quite troublesome. In addition, when replacing the fabric cover, piperazine compounds may fall off, which could cause harm to the workers if inhaled. Utility Model Content

[0005] The purpose of this invention is to provide a cooling and conveying device for piperazine compounds to solve the problems mentioned in the background art.
