Description

Technical Field

[0001] This utility model relates to the technical field of oxytetracycline production equipment, specifically a raw material feeding device for oxytetracycline production. Background Technology

[0002] The preparation of oxytetracycline usually requires fermentation in a fermenter. During the fermentation process, materials are continuously consumed and need to be replenished multiple times. In existing technologies, many materials are replenished by manually opening the feeding pipe. This method is not only inefficient, but the replenished materials fall naturally and are prone to clogging at the feeding port. In addition, the replenished materials include liquid, solid and powder materials, which are prone to agglomeration and insufficient mixing, affecting the subsequent fermentation effect. To solve the above problems, a raw material feeding device for oxytetracycline production is needed.

[0003] An existing raw material feeding device for oxytetracycline production cannot simultaneously feed multiple materials. Frequent feeding leads to uneven feeding, affecting fermentation quality. Inconsistent mixing during feeding causes liquid, solid, and powdered materials to easily clump together, causing blockages. Therefore, there is an urgent need for a raw material feeding device for oxytetracycline production. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a raw material feeding device for oxytetracycline production, so as to solve the problems that existing raw material feeding devices for oxytetracycline production cannot simultaneously feed multiple materials, and frequent feeding will lead to uneven feeding, affecting fermentation quality, uneven mixing during feeding, and easy agglomeration of various materials such as liquids, solids, and powders, causing blockage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material feeding device for oxytetracycline production, comprising a storage tank, a feeding hopper installed on the inner wall of the storage tank, a limiting rod installed on the inner wall of the feeding hopper, a return spring installed on the outer wall of the limiting rod, a plug installed at the bottom of the limiting rod, a fixed bracket installed on the top of the storage tank, a drive motor installed on the top of the fixed bracket, a transmission rod installed at the bottom of the drive motor, a stirring rod installed on the outer wall of the transmission rod, and a spiral rod installed at the bottom of the transmission rod.

[0006] Preferably, the feed hoppers are arranged in a rectangular array with the central axis of the storage tank as the center, and the limiting rods form a telescopic structure with the feed hoppers through a return spring.

[0007] Preferably, the plug is cone-shaped and fits tightly against the inner wall of the feed hopper.

[0008] Preferably, the transmission rod forms a rotating structure with the fixed bracket via a drive motor, and the stirring rods are arranged in a circular array with the central axis of the storage tank as the center.

[0009] Preferably, the stirring rod is in close contact with the inner wall of the storage tank, and the outer diameter of the spiral rod matches the bottom inner diameter of the storage tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes a storage tank, a feeding hopper, a limiting rod, a return spring, and a plug. Materials to be added are placed into the feeding hopper, where the plug is pushed upwards by the return spring, sealing it against the inner wall of the feeding hopper. This allows for temporary storage of the materials. When additional material is needed, pressing the limiting rod causes the plug to move downwards, separating it from the inner wall of the feeding hopper, allowing for simultaneous feeding of the added material. This avoids frequent feeding, improving feeding efficiency and fermentation effect.

[0012] This invention utilizes a drive motor, transmission rod, stirring rod, and screw rod. When additional material is added to the storage tank, the drive motor is activated to rotate the transmission rod. At the same time, the stirring rod evenly mixes the added material, improving the mixing effect. Simultaneously, the screw rod delivers the material in a spiral manner, preventing the added material from accumulating and clogging at the bottom of the storage tank. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Please see Figures 1-4 A raw material feeding device for oxytetracycline production includes a storage tank 1. The device is characterized by: a feeding hopper 2 installed on the inner wall of the storage tank 1; a limiting rod 3 installed on the inner wall of the feeding hopper 2; a return spring 4 installed on the outer wall of the limiting rod 3; and a plug 5 installed at the bottom of the limiting rod 3. The feeding hoppers 2 are arranged in a rectangular array around the central axis of the storage tank 1, and the limiting rod 3 and the feeding hopper 2 form a telescopic structure via the return spring 4. The plug 5 is conical in shape and fits tightly against the inner wall of the feeding hopper 2. The system consists of a storage tank 1, a feeding hopper 2, a limiting rod 3, a return spring 4, and a plug 5. Materials to be added are placed into the feeding hopper 2. The plug 5 is then pushed upwards by the return spring 4, sealing it against the inner wall of the feeding hopper 2, allowing for temporary storage of the added materials. When additional material is needed, pressing the limiting rod 3 causes the plug 5 to move downwards, separating it from the inner wall of the feeding hopper 2, allowing for simultaneous feeding of the added material. This avoids frequent feeding, improving feeding efficiency and fermentation effect.

[0021] Please see Figures 1-4 A raw material feeding device for oxytetracycline production includes a storage tank 1 with a fixed support 6 mounted on top, a drive motor 7 mounted on top of the fixed support 6, a transmission rod 8 mounted on the bottom of the drive motor 7, a stirring rod 9 mounted on the outer wall of the transmission rod 8, and a spiral rod 10 mounted on the bottom of the transmission rod 8. The transmission rod 8 and the fixed support 6 form a rotating structure through the drive motor 7. The stirring rods 9 are arranged in a circular array around the central axis of the storage tank 1, and are in close contact with the inner wall of the storage tank 1. The outer diameter of the spiral rod 10 matches the inner diameter of the bottom of the storage tank 1. When additional material is added to the storage tank 1 via the drive motor 7, transmission rod 8, stirring rod 9, and spiral rod 10, the drive motor 7 is activated to rotate the transmission rod 8. At this time, the stirring rod 9 uniformly stirs the added material, improving the mixing effect. Simultaneously, the spiral rod 10 feeds the material in a spiral manner, preventing the added material from accumulating and clogging at the bottom of the storage tank 1.

[0022] Working principle: In use, the materials to be added are first placed into the feed hopper 2. At this time, the plug 5 is pushed upward by the spring force of the return spring 4, so that the plug 5 is sealed with the inner wall of the feed hopper 2, which can temporarily store the materials to be added. When it is necessary to add materials, the limit rod 3 is pressed, and the plug 5 is moved downward, so that the plug 5 is separated from the inner wall of the feed hopper 2, thereby allowing the added materials to be fed at the same time, avoiding multiple additions, improving the addition efficiency and fermentation effect. Then, when the added materials are added into the storage tank 1, the drive motor 7 is started to drive the transmission rod 8 to rotate. At this time, the stirring rod 9 stirs the added materials evenly, improving the mixing effect. At the same time, the screw rod 10 feeds the mixed materials into the fermentation tank, which can prevent the added materials from accumulating and blocking at the bottom of the storage tank 1. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
