Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical production equipment, and particularly relates to a drying device for norfloxacin materials. Background Art

[0002] Norfloxacin, a broad-spectrum antibiotic. Odorless, slightly bitter taste, grayish-white to pale yellow crystalline powder; can absorb moisture in the air, and the color gradually becomes darker when exposed to light. This product can hinder the DNA gyrase of pathogenic bacteria in the digestive tract, hinder the replication of bacterial DNA, and has an inhibitory effect on bacteria. It is a commonly used drug for treating enteritis and dysentery.

[0003] In the fields of pharmaceutical and fine chemical production, the drying of materials is a crucial step, directly affecting the quality and production efficiency of products. As a widely used antibiotic raw material, the drying process of norfloxacin is particularly critical. It not only requires thorough drying to ensure the stability and purity of drugs, but also needs to ensure mild drying conditions to avoid damaging the chemical structure and biological activity of drugs. Traditional drying methods, such as natural air drying or static hot air drying, often have problems such as uneven drying, low efficiency, high energy consumption, and possible material contamination, and cannot meet the requirements of high-quality standards and large-scale production. Content of the Utility Model

[0004] In view of this, the utility model provides a drying device for norfloxacin materials, which provides sufficient thermal energy for norfloxacin materials through the hot water in the outer box and the third water pipe, enables the materials to be fully dried through bidirectional heat radiation, and scatters the piled-up materials through the rotating shaft to ensure that the materials in the inner box can be fully affected by heat radiation, thereby ensuring the drying work of the materials.

[0005] To solve the above technical problems, the utility model provides a drying device for norfloxacin materials, including an outer box and an inner box. The outer box is provided with a drying mechanism for heating the inner box. The drying mechanism includes a heating component and a circulation component. The inner box is also provided with a stirring mechanism for assisting the drying mechanism to heat. The heating component includes a placement table arranged on the outer box and heating pipes arranged in a circular manner inside the outer box. The circulation component includes a fixing frame arranged on the outer box and a two-way water pump arranged on the fixing frame. The stirring mechanism includes a rotating motor arranged on the top of the inner box and a rotating shaft arranged inside the inner box. By injecting water into the outer box and providing necessary heat for the heating pipes through an electric heater, the heating pipes heat the water in the outer box, which in turn heats the inner box, and then heats the materials in the inner box through heat transfer. In addition, the hollow rotating shaft is used to accommodate the hot water pumped from the outer box by the water pump to realize the heating work of norfloxacin materials in the inner box. The hot water inside the outer box and the rotating shaft realizes the circulating heat supply to norfloxacin materials, enabling norfloxacin materials to be fully affected by heat radiation, achieving sufficient drying, and improving the drying efficiency.

[0006] An electric heater for providing heat source to the heating tube is provided on the placement table. The end of the heating tube penetrates through the box wall of the outer box and is connected to the electric heater. The heat provided by the electric heater to the heating tube heats the water source in the outer box, and heats the materials in the inner box through the heat transfer of water.

[0007] A first water pipe is connected to the bottom of the two-way water pump, and a second water pipe is connected to the top of the two-way water pump. The two-way water pump is used to extract the water source in the outer box, promote the circulation of the liquid in the outer box, and assist in regulating the temperature and improving the drying efficiency.

[0008] The end of the output shaft of the rotating motor is connected with a main gear. The rotating shaft is rotatably arranged on the bottom surface of the inner box through a bearing. A number of stirring rollers are sleeved on the rotating shaft. The rotating motor installed on the top of the inner box is connected to the main gear through the output shaft. The main gear meshes with the sub-gear on the rotating shaft, driving the rotating shaft and the stirring rollers thereon to rotate, which not only promotes the turning of the materials, increases the contact area with the hot air, but also helps to prevent the materials from caking and speeds up the drying speed.

[0009] A rotating joint is connected to the top of the rotating shaft, and a sub-gear is sleeved on the rotating joint. The main gear and the sub-gear mesh with each other. Through the rotating joint, the rotating shaft can still be connected to the second water pipe outside through the third water pipe when rotating, maintaining the water flow circulation and ensuring that the hot water in the rotating shaft provides heat source for the materials.

[0010] A third water pipe is arranged inside the rotating shaft, and the top end of the third water pipe is connected to the tail end of the second water pipe.

[0011] The inner box is sleeved inside the outer box and is located within the annular circle of the heating tube. By positioning the inner box in the annular area formed by the heating tube, on the one hand, it heats the water in the outer box, and on the other hand, it can heat the inner box through the heating tube, effectively utilizing the heat to dry the materials in the inner box.

[0012] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0013] 1. The electric heater provides the necessary heat to the heating tube, which heats the water injected into the outer box by the heating tube, and heats the materials in the inner box through the heat transfer of water, ensuring the uniformity of heat distribution.

[0014] 2. The rotating motor on the top of the inner box is connected to the main gear through the output shaft. The main gear meshes with the sub-gear on the rotating shaft, driving the rotating shaft and the stirring shaft thereon to rotate. The hollow design of the rotating shaft and the stirring rollers enables hot water heated in the outer box to be introduced into their interiors. This not only promotes the turning of the materials, increases the contact area with the hot air, but also helps to prevent the materials from caking and speeds up the drying speed.

[0015] 3. The design of the rotary joint allows the rotating shaft to still be connected to the external second water pipe through the third water pipe during rotation, maintaining the water flow circulation, enabling the third water pipe to inject hot water into the hollow rotating shaft and the inside of the stirring roller, so that the material can be further heat-treated to optimize the drying conditions.

[0026] In an embodiment of the present invention, as Figure 1 shown, a main gear 43 is connected to the end of the output shaft of the rotating motor 41. The rotating shaft 42 is rotatably arranged on the bottom surface of the inner box 2 through bearings. A plurality of stirring rollers 44 are sleeved on the rotating shaft 42.
