Description

Technical Field

[0001] This utility model belongs to the field of vecuronium bromide production technology, and in particular relates to a drying device for vecuronium bromide production. Background Technology

[0002] Vecuronium bromide, also known as vecuronium bromide, is a white or off-white powder, odorless, bitter in taste, and hygroscopic. It is readily soluble in ethanol, slightly soluble in water, and practically insoluble in ether; it is also readily soluble in dilute hydrochloric acid. Vecuronium bromide is an anesthetic (skeletal muscle relaxant), mainly used clinically in combination with general anesthetics for various surgeries, and can also be used for endotracheal intubation during general anesthesia.

[0003] The synthesis of vecuronium bromide involves sequential steps including crystallization, centrifugation, drying, and packaging. During drying, the crystallized vecuronium bromide is typically added to the drying oven. However, when too much vecuronium bromide is added, the powder clumps together, preventing the inner layers from drying effectively. This results in poor drying efficiency and poor overall drying performance. Therefore, the existing technology still has shortcomings and deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for the production of vecuronium bromide to solve the above-mentioned problems.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A drying apparatus for vecuronium bromide production is provided, comprising a drying chamber with a feed hopper at the top, the feed hopper being connected to the interior of the drying chamber. The feed hopper is funnel-shaped and contains two sets of feeding mechanisms symmetrically arranged. Each feeding mechanism includes a baffle plate and a telescopic rod. One side of the baffle plate is hinged to the inner wall of the feed hopper, and the telescopic rod is located below the baffle plate, with one end hinged to the inner wall of the feed hopper. The piston end of the telescopic rod is connected to the baffle plate. The material plate is hinged, and a motor is also provided on the feeding hopper. The motor is fixedly installed on the outer wall of the feeding hopper. A rotating shaft is fixedly connected to the output shaft of the motor. The rotating shaft is horizontally arranged, and both ends of the rotating shaft pass through the feeding hopper and are rotatably connected to the feeding hopper through bearings. Multiple stirring blades are fixedly connected to the part of the rotating shaft located inside the feeding hopper. Multiple sets of horizontally arranged conveyor belts are arranged inside the drying chamber. The multiple sets of conveyor belts are arranged in the vertical direction, and the conveying directions of two connected conveyor belts are opposite. A material drop plate is fixedly connected to the inner wall of the drying chamber.

[0007] Furthermore, the piston end of the telescopic rod is hinged to the bottom of the baffle plate.

[0008] Furthermore, the material drop plate is inclined and located between two adjacent transmission belts.

[0009] Furthermore, one side of the discharge plate is fixedly connected to the inner wall of the drying chamber, and the other side of the discharge plate is located above the lower conveyor belt. By setting the discharge plate, vecuronium bromide located on the upper conveyor belt can be guided to the lower conveyor belt.

[0010] Furthermore, a discharge pipe is provided on the side wall of the drying chamber, the discharge pipe is connected to the inside of the drying chamber, and the discharge pipe is located near the bottom conveyor belt.

[0011] Furthermore, the drying chamber is also equipped with multiple hot air blowers, each of which is connected to an air outlet pipe. The multiple air outlet pipes are connected by a connecting pipe located inside the drying chamber. The connecting pipe is horizontally positioned and has multiple air outlets, which are evenly distributed at equal intervals along the connecting pipe.

[0012] Furthermore, the telescopic rod is an electric push rod.

[0013] Furthermore, multiple stirring blades are evenly distributed at equal intervals along the rotating shaft.

[0014] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0015] In the drying device for vecuronium bromide production provided by this utility model, the vecuronium bromide material falls into the conveyor belt inside the drying chamber through the feeding mechanism in the feeding hopper. The material is conveyed forward on the conveyor belt, and the subsequently added material will not accumulate on the previously added material, thus avoiding the complete accumulation of vecuronium bromide material. Moreover, by adjusting the gap between the two baffles, the feed rate of vecuronium bromide material can be adjusted to prevent the vecuronium bromide material from accumulating too thickly on the conveyor belt, thereby improving the drying effect of the vecuronium bromide material.

[0021] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a drying device for the production of vecuronium bromide, which is used to dry vecuronium bromide powder during the production process of vecuronium bromide, so as to facilitate the subsequent packaging of vecuronium bromide.

[0023] like Figure 1 and Figure 2 As shown, the drying device for vecuronium bromide production includes a drying chamber 10, and a feed hopper 11 is provided on the top of the drying chamber 10. The feed hopper 11 is connected to the inside of the drying chamber 10. The feed hopper 11 is roughly funnel-shaped. This arrangement facilitates the addition of vecuronium bromide to be dried into the drying chamber 10.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the feeding hopper 11 is further provided with two sets of feeding mechanisms 12. Each feeding mechanism 12 includes a baffle plate 121 and a telescopic rod 122. The two sets of feeding mechanisms 12 are symmetrically arranged. One side of the baffle plate 121 is hinged to the inner wall of the feeding hopper 11. The telescopic rod 122 is located below the baffle plate 121, and one end of the telescopic rod 122 is hinged to the inner wall of the feeding hopper 11. The piston end of the telescopic rod 122 is hinged to the baffle plate 121. Specifically, the piston end of the telescopic rod 122 is hinged to the bottom of the baffle plate 121. In this embodiment, the telescopic rod 122 is an electric push rod. In other embodiments, the telescopic rod 122 can be a cylinder or the like.

[0025] like Figure 1 and Figure 2 As shown, a motor 111 is also provided on the feed hopper 11. The motor 111 is fixedly installed on the outer wall of the feed hopper 11. A rotating shaft 112 is fixedly connected to the output shaft of the motor 111. The rotating shaft 112 is horizontally arranged. Both ends of the rotating shaft 112 pass through the feed hopper 11 and are rotatably connected to the feed hopper 11 through bearings. A plurality of stirring blades 113 are fixedly connected to the part of the rotating shaft 112 located inside the feed hopper 11. The plurality of stirring blades 113 are evenly distributed at equal intervals along the rotating shaft 112.

[0026] By setting up a motor 111 and a rotating shaft 112, the motor 111 can drive the rotating shaft 112 to rotate when it is working. The multiple stirring blades 113 on the rotating shaft 112 will rotate accordingly, thereby stirring the material inside the feed hopper 11, preventing the material from accumulating above the baffle plate 121, increasing the fluidity of the material, and making it easier for the material to fall downward into the drying chamber 10.

[0027] like Figure 1 and Figure 2 As shown, the drying chamber 10 is equipped with multiple sets of horizontally arranged conveyor belts 13. These conveyor belts 13 are arranged vertically, and the conveying directions of two connected conveyor belts 13 are opposite. Specifically, in this embodiment, there are three sets of conveyor belts 13, with the uppermost conveyor belt 13 conveying in a clockwise direction.

[0028] like Figure 1 and Figure 2 As shown, a discharge plate 14 is fixedly connected to the inner wall of the drying chamber 10. The discharge plate 14 is inclined and located between two adjacent conveyor belts. One side of the discharge plate 14 is fixedly connected to the inner wall of the drying chamber 10, and the other side of the discharge plate 14 is located above the lower conveyor belt 13. By setting the discharge plate 14, vecuronium bromide located on the upper conveyor belt 13 can be guided to the lower conveyor belt 13.

[0029] like Figure 1 and Figure 2 As shown, a discharge pipe 15 is provided on the side wall of the drying chamber 10. The discharge pipe 15 is connected to the interior of the drying chamber 10 and is located near the bottom conveyor belt 13.

[0030] like Figure 1 and Figure 2As shown, the drying chamber 10 is also equipped with multiple hot air blowers 16, each of which is connected to an air outlet pipe 161. These multiple air outlet pipes 161 are connected by a connecting pipe 162 located inside the drying chamber 10 and horizontally positioned. The connecting pipe 162 has multiple air outlets 163, which are evenly distributed at equal intervals along the connecting pipe 162.

[0031] like Figure 1 and Figure 2 As shown, the bottom of the drying chamber 10 is fixedly connected with support legs 17, which are evenly distributed at the bottom of the drying chamber 10. Specifically, in this embodiment, there are four support legs 17.

[0032] The drying device for vecuronium bromide production provided by this utility model, in use, adds vecuronium bromide to be dried into the drying chamber 10 through the feed hopper 11. The two baffles 121 are initially in a horizontal state, thus sealing the inside of the feed hopper 11. The material added into the feed hopper 11 falls above the baffles 121. During operation, the extension and retraction of the telescopic rod 122 causes the baffles 121 to rotate at a certain angle. As the baffles 121 tilt, the material above the baffles 121 falls into the drying chamber 10 through the gap between the two baffles 121. Moreover, the tilt angle of the baffles 121 can be adjusted by the telescopic rod 122, changing the size of the gap between the two baffles 121, thereby controlling the amount of material fed.

[0033] The vecuronium bromide material entering the drying chamber 10 falls onto the conveyor belt 13 and is conveyed forward, then falls onto the lower conveyor belt 13 through the drop plate 14. The hot air blower 16 blows hot air into the drying chamber 10 through the air outlet 163 to heat and dry the vecuronium bromide material on the conveyor belt 13 inside the drying chamber 10. The dried vecuronium bromide material is finally discharged from the discharge pipe 15.

[0034] In the drying device for vecuronium bromide production provided by this utility model, the vecuronium bromide material falls into the conveyor belt 13 inside the drying chamber 10 through the feeding mechanism 12 in the feeding hopper 11. The material is conveyed forward on the conveyor belt 13, and the material added later will not accumulate on the material added earlier, which can prevent the vecuronium bromide material from piling up together. Moreover, by adjusting the gap between the two baffles 121, the feed rate of the vecuronium bromide material can be adjusted to prevent the vecuronium bromide material from accumulating too thickly on the conveyor belt 13, thereby improving the drying effect of the vecuronium bromide material.
