Description

Technical Field

[0001] This utility model relates to the field of solution specific gravity detection technology, and in particular to a specific gravity detection alarm device for the production of celecoxib. Background Technology

[0002] Celecoxib is a new generation of nonsteroidal anti-inflammatory analgesic that selectively inhibits cyclooxygenase to suppress prostaglandin production, thereby achieving anti-inflammatory and analgesic effects. It is primarily manufactured in hard capsule form. Because the preparation of celecoxib involves a multi-stage reaction, careful attention must be paid to changes in the solution's specific gravity throughout the entire reaction process.

[0003] Currently, the conventional procedure for detecting the specific gravity of a solution during a reaction is to take a sample from the reaction vessel and then measure it using a specific gravity meter. Since the entire reaction process is a multi-stage reaction, it is necessary to take samples and test them repeatedly, which is cumbersome and affects production efficiency.

[0004] To address this issue, we propose a specific gravity detection alarm device for celecoxib production. Utility Model Content

[0005] The purpose of this invention is to provide a specific gravity detection alarm device for celecoxib production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A specific gravity detection alarm device for celecoxib production includes a detection cylinder with a mounting plate fixed on it. An alarm box is mounted on the mounting plate, and a controller and an audible and visual alarm are installed on the alarm box. The detection cylinder contains a float ring and a float cylinder, with the float ring surrounding the float cylinder. A distance sensor is installed on the float ring to detect the distance between the float ring and the float cylinder. The float ring and float cylinder are supported by a bracket, and the edge of the bracket extends out of a groove on the surface of the detection cylinder and is fitted with a sliding sleeve. A screw is threaded through and screwed into the sliding sleeve, and one end of the screw is connected to a motor.

[0008] In a further embodiment, lead pellets are uniformly placed inside the float ring and the float cylinder.

[0009] In a further embodiment, the bracket is fixed with a tray one for supporting the float ring and a tray two for supporting the float cylinder, and the center lines of the tray one and the tray two coincide with each other.

[0010] In a further embodiment, the upper ports of tray one and tray two adopt an outwardly expanding open structure.

[0011] In a further embodiment, both tray one and tray two have several through holes on their surfaces.

[0012] In a further embodiment, there are two sliding sleeves symmetrically distributed about the bracket, and the interior of the other sliding sleeve has a sliding rod parallel to the screw.

[0013] In a further embodiment, the outer wall of the sliding sleeve is provided with a raised edge, and a plug rod is connected to the lower part of the raised edge, and a nut is threadedly screwed onto one end of the plug rod that protrudes from the flange of the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a detection cylinder that can be mounted on a reaction vessel via a mounting plate, allowing the float and buoy to be directly inserted into the reaction vessel for easy specific gravity testing. It utilizes the different buoyancy of the float and buoy in different solutions to measure specific gravity changes, eliminating the need for repeated sampling and testing. Furthermore, the float and buoy can be raised and lowered under the control of the sliding sleeve and screw, allowing them to be raised away from the solution during stirring reactions within the reaction vessel to prevent the solution from overturning them. When testing is required in the next reaction stage, they can be lowered to contact the liquid surface for detection. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 A specific gravity detection alarm device for celecoxib production includes a detection cylinder 1 with an open lower end. A mounting plate 2, a flange, is fixed to the detection cylinder 1 for easy installation at the detection port of the reactor. An alarm box 3 is mounted on the mounting plate 2, and a controller 4 and an audible and visual alarm 5 are installed on the alarm box 3. Inside the detection cylinder 1 are a float ring 6 and a float cylinder 7, with the float ring 6 surrounding the float cylinder 7. A distance sensor 8 is mounted on the float ring 6 to detect the distance between it and the float cylinder 7. When the specific gravity of the solution is within a reasonable range, the distance detected by the distance sensor 8 is also within a safe range. However, when the liquid concentration changes, the buoyancy force on the float ring 6 and the float cylinder 7 also changes. Since the cross-sectional area of ​​the float ring 6 is larger than that of the float cylinder 7, the movement of the float ring 6 is less than that of the float cylinder 7, thus causing a change in the distance detected by the distance sensor 8. When the controller 4 receives the signal change from the distance sensor 8, it controls the audible and visual alarm 5 to issue an alarm, alerting the staff that the specific gravity of the solution has changed.

[0025] Please see Figure 3 To ensure that the float ring 6 and float 7 float more stably on the solution, reduce shaking, and improve detection accuracy, lead pellets 14 are evenly placed on the float ring 6 and float 7 to ensure that the float ring 6 and float 7 float vertically on the liquid surface.

[0026] Please see Figure 1-3 Considering that the synthesis reaction of celecoxib is a multi-stage reaction that requires multiple measurements in actual use, and that multiple solutions need to be stirred during the reaction in the reactor, the float ring 6 and float cylinder 7 are easily overturned by the stirred solution if they remain on the liquid surface, affecting subsequent measurements. Therefore, the float ring 6 and float cylinder 7 are supported by a bracket 9, and the edge of the bracket 9 extends out of the groove on the surface of the detection cylinder 1 and is fitted with a sliding sleeve 10. A screw 11 is threaded through and screwed into the sliding sleeve 10. The screw 11 is parallel to the detection cylinder 1, and both ends of the screw 11 are rotatably connected to the detection cylinder 1. One end of the screw 11 extends out of the mounting plate 2 and is connected to a motor 12. The main body of the motor 12 is fixed on the mounting plate 2. The motor 12 drives the screw 11 to rotate, thereby using the sliding sleeve 10 and the bracket 9 to raise the float ring 6 and float cylinder 7 away from the liquid surface.

[0027] Furthermore, there are two sliding sleeves 10 symmetrically distributed about the bracket 9, and the inner sliding sleeve 10 has a sliding rod 13 parallel to the screw 11. By sliding the sliding sleeve 10 outside the sliding rod 13, the bracket 9 can be limited to ensure the stability of the bracket 9 when it is raised and lowered.

[0028] Please see Figure 2-4 To improve the support effect of the bracket 9, a tray 91 for supporting the float ring 6 and a tray 92 for supporting the float cylinder 7 are fixed on the bracket 9. The center lines of the tray 91 and the tray 92 coincide with each other. The upper ports of the tray 91 and the tray 92 adopt an outwardly expanding open structure to facilitate docking with the float ring 6 and the float cylinder 7. Several through holes 93 are opened on the surface of the tray 91 and the tray 92 to facilitate the flow of solution, thereby reducing the swaying of the float ring 6 and the float cylinder 7 when placed in the liquid.

[0029] Please see Figure 3 To facilitate the maintenance of the float ring 6 and the float 7, a protruding edge 101 is provided on the outer wall of the sliding sleeve 10. A rod 102 is connected to the lower part of the protruding edge 101, and a nut 103 is threaded onto one end of the rod 102 that passes through the flange of the bracket 9, making it easy to disassemble the bracket 9 relative to the sliding sleeve 10. Furthermore, the groove on the surface of the detection cylinder 1 passes through the lower port, allowing the protruding edge 101 to slide out from the lower end of the groove.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
