Description

Technical Field

[0001] This utility model belongs to the field of injection production technology, and specifically relates to an injection production equipment. Background Technology

[0002] Bumetanib is a derivative of m-aminobenzenesulfonamide and is a potent diuretic. Clinically, its site of action, mechanism of action, and characteristics are similar to those of furosemide and ethacrynic acid. It is mainly used to treat liver disease, heart failure, and kidney disease. Bumetanib injection is prepared by diluting the active pharmaceutical ingredient bumetanib with the excipient sodium chloride.

[0003] Existing injection production equipment, while capable of diluting and mixing various raw materials, typically employs a scraping structure to remove and clean materials to prevent them from adhering to the inner wall of the device and affecting the mixing effect and the thoroughness of the discharge. However, the scraping structure often rotates simultaneously with the mixing structure. Since the basic structure needs to rotate continuously during production, while the scraping structure only needs to rotate when scraping is required, the scraping structure will work ineffectively for extended periods, easily leading to severe wear and tear in a short time, thus affecting its service life and failing to fully meet user needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an injection production equipment that not only meets the basic requirements for diluting and mixing various raw materials, but also allows the scraping structure to rotate only when it is necessary to scrape and clean the material adhering to the inner wall of the equipment, thereby extending the service life of the scraping structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an injection liquid production equipment, including a mixing tank, an installation shaft is rotatably installed through the top of the mixing tank, a scraper frame is installed on the installation shaft, a stirring shaft is rotatably installed at the bottom of the mixing tank, a stirring blade is installed on the stirring shaft, an installation cylinder is rotatably installed at the bottom of the mixing tank and sleeved on the outside of the stirring shaft, a connecting shaft is rotatably installed at the side end of the mixing tank through an installation plate, a fixing bolt for fixing the stirring shaft is installed on the installation cylinder, a threaded fixing cylinder is installed on the stirring shaft and screwed to the fixing bolt, and a through hole is opened on the scraper frame to rotatably connect with the stirring shaft.

[0006] As a further improvement of this utility model, the rotation transmission module includes a second pulley transmission assembly disposed between the connecting shaft and the mounting shaft, and a first pulley transmission assembly disposed between the connecting shaft and the mounting cylinder.

[0007] As a further improvement of this utility model, a drive motor is also provided at the bottom of the mixing tank, and a gear transmission assembly is provided between the output shaft of the drive motor and the stirring shaft.

[0008] As a further improvement of this invention, a transparent observation window is also provided on the mixing tank. The transparent observation window facilitates real-time monitoring of the internal mixing status.

[0009] As a further improvement of this utility model, a feed hopper is provided at the top of the mixing tank, and a discharge pipe is provided at the bottom of the mixing tank, with a control valve installed on the discharge pipe. The feed hopper on the mixing tank facilitates the addition of raw materials; the discharge pipe, in conjunction with the control valve, allows for precise control of the discharge of the finished drug solution.

[0010] As a further improvement of this utility model, the bottom of the mixing tank is also provided with support legs.

[0011] As a further improvement of this utility model, the fixing bolt is a hand-tightening bolt. Installation or disassembly can be completed without tools, improving operational efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the mixing shaft and mixing blades can mix various raw materials in the mixing tank. Secondly, the mounting cylinder, fixing bolts, and threaded fixing cylinder work together to drive the mounting cylinder to rotate only when the scraper needs to be rotated. This, in turn, drives the mounting shaft and scraper frame to rotate with the help of the connecting shaft, the first belt pulley drive assembly, and the second belt pulley drive assembly, thereby reducing unnecessary wear and extending the service life of the scraper structure.

[0014] Secondly, the stirring shaft can be rotated by the combination of the drive motor and the gear transmission assembly. Attached Figure Description

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown in Figure 3, an injection production device includes a mixing tank 101. A mounting shaft 102 is rotatably mounted on the top of the mixing tank 101 through a first bearing 112. A scraper frame 103 is mounted on the mounting shaft 102. A stirring shaft 104 is rotatably mounted on the bottom of the mixing tank 101. A stirring blade 105 is mounted on the stirring shaft 104. A mounting cylinder 106, sleeved on the outside of the stirring shaft 104, is rotatably mounted on the bottom of the mixing tank 101 through a second bearing 113. A mounting plate 119 is fixedly connected to the side end of the mixing tank 101. A connecting shaft 107 is rotatably mounted on the mounting plate 119 through a third bearing 114. A through hole is also provided on the mounting plate 119 for rotatably connecting with the connecting shaft 107. A fixing bolt 110 for fixing the stirring shaft 104 is provided on the mounting cylinder 106. A threaded fixing cylinder 111 is screwed onto the stirring shaft 104 and connected to the fixing bolt 110. A through hole is provided on the scraper frame for rotatably connecting with the stirring shaft 104. The 110 fixing bolt is a hand-tightening bolt. Installation or removal can be completed without tools, improving operational efficiency.

[0022] like Figure 1 As shown, the rotational transmission module includes a second pulley transmission assembly 109 disposed between the connecting shaft 107 and the mounting shaft 102, and a first pulley transmission assembly 108 disposed between the connecting shaft 107 and the mounting cylinder 106.

[0023] like Figure 1As shown, the mixing tank 101 has a feed hopper 115 at the top and a discharge pipe 116 at the bottom, with a control valve 117 installed on the discharge pipe 116. The feed hopper 115 facilitates the addition of raw materials; the discharge pipe 116, in conjunction with the control valve 117, allows for precise control of the discharge of the finished drug solution. The bottom of the mixing tank 101 also has support legs 118.

[0024] like Figure 1 As shown, a drive motor 201 is also provided at the bottom of the mixing tank 101, and a gear transmission assembly 202 is provided between the output shaft of the drive motor 201 and the stirring shaft 104.

[0025] Workers can add the required raw materials into the mixing tank 101 through the feed hopper 115, and then start the drive motor 201. The gear transmission assembly 202 drives the stirring shaft 104 to rotate, and the stirring blades 105 on the stirring shaft 104 fully mix the various raw materials in the mixing tank 101.

[0026] During the mixing process, to prevent material from adhering to the inner wall of the mixing tank 101, the drive motor 201 can be stopped first, causing the stirring shaft 104 to stop and the position of the threaded fixing cylinder 111 to correspond to the fixing bolt 110. Then, the fixing bolt 110 and the threaded fixing cylinder 111 are screwed together. After that, the drive motor 201 can be restarted, driving the connecting shaft 107 to rotate through the second belt pulley transmission assembly 109. This, in turn, drives the mounting shaft 102 and the scraper frame 103 to rotate through the first belt pulley transmission assembly 108, removing the material adhering to the inner wall. After cleaning is completed, the drive motor 201 is stopped, causing the fixing bolt 110 to separate from the threaded fixing cylinder 111, stopping the rotation of the mounting cylinder 106, and the scraper frame 103 stops accordingly, avoiding unnecessary wear.

[0027] After dilution and mixing are completed, simply open control valve 117 to discharge the material through discharge pipe 116.

[0028] In order to ensure thorough discharge, the fixing bolt 110 can be temporarily connected to the threaded fixing cylinder 111 to drive the scraper frame 103 to rotate, thereby preventing the material from adhering to the inner wall of the mixing tank 101 and thus ensuring thorough discharge.

[0029] According to another embodiment of the present invention, such as Figure 1 As shown, a transparent observation window 203 is also provided on the mixing tank 101. Through the transparent observation window 203, workers can easily monitor the internal mixing status in real time.

[0030] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
