Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical production, and particularly relates to a pharmaceutical forced-air oven. Background Art

[0002] During the pharmaceutical production process, an oven may be required to remove moisture or other solvents to ensure the stability of the medicine and meet the quality standards, and this needs to be completed through a corresponding oven.

[0003] A forced-air oven is an oven with a forced convection heating system. It evenly distributes hot air throughout the working chamber through a built-in fan, thereby achieving a fast and uniform heating effect. The forced-air oven is particularly suitable for application scenarios that require rapid drying, curing, or aging tests, such as material tests in laboratories, drying treatment of electronic components, etc.

[0004] When the existing oven dries medicines, with the continuous operation of the oven, there will be relatively high heat inside. Although the drying objects can be replaced intermittently, the temperature of the placement structure inside the box will increase and exceed the heat-receiving temperature of the medicines. This causes the medicines placed at the bottom to come into contact with the placement structure, resulting in uneven heat reception between the bottom medicines and the top medicines, and it is impossible to better ensure the balance of the placement structure during continuous operation; and when external air enters the box, external dust will enter the interior, resulting in the cleanliness of the box and the medicines not being guaranteed.

[0005] Therefore, this application proposes a pharmaceutical forced-air oven. Content of the Utility Model

[0028] Embodiment 1

[0029] In order to solve the technical problems in the background technology, a pharmaceutical blowing oven is provided as follows:

[0030] Combined with Figures 1 - 6 As shown, a pharmaceutical blowing oven provided by the present invention includes a box body 1, a heating component 4 is fixedly installed at the top inside the box body 1, a cooling type placement component 5 is fixedly installed inside the box body 1, a support component 2 is fixedly installed at the bottom of the box body 1, a blowing component 7 is fixedly installed inside the support component 2, the output end of the blowing component 7 is butt - installed with a filter component 6, and the end of the filter component 6 is installed and connected with the heating component 4. A shunt component 8 is fixedly installed on one side of the box body 1. The input end of the shunt component 8 is communicated with the output path of the blowing component 7, and the output end is installed and connected with the cooling type placement component 5. A recycling component 3 is fixedly installed on the other side of the box body 1;

[0031] During this period, the personnel place the medicines to be dried on the temperature-reducing placement component 5, close the box door for operation, start the heating component 4 and the air-blowing component 7 for drying operation. And while the air-blowing component 7 is guiding the air, it will cooperate with the shunt component 8 for shunting, shunting the air delivered by the air-blowing component 7. Through the mutual cooperation of the shunt component 8 and the temperature-reducing placement component 5, the unheated air can be introduced into the temperature-reducing placement component 5 to cool the placement structure of the medicines, avoiding the situation that the internal placement structure temperature is too high due to the long-term operation of the drying box, reducing the influence on the bottom medicine placement surface during drying, ensuring that the medicines are more balanced during drying. The heat generated during drying can be recovered by using the recovery component 3 to increase the energy-saving effect of the drying box. The air introduced into the box body can be filtered by the filter component 6 to remove particulate dust in the air, ensuring the cleanliness of the introduced air and avoiding affecting the internal medicines.

[0032] The temperature-reducing placement component 5 includes a hollow placement tube 51, an intake main pipe 52, and an exhaust main pipe 57; the shunt component 8 includes a shunt tube 81; the intake main pipe 52 and the exhaust main pipe 57 are fixedly installed inside the box body 1 respectively, and the hollow placement tubes 51 communicating with each other are evenly distributed between the intake main pipe 52 and the exhaust main pipe 57. The output path of the air-blowing component 7 is butt-connected with a shunt tube 81, and the shunt tube 81 is communicated with 52; the heating component 4 includes a gas-guiding cavity 41, a gas-guiding port 42, a resistance heating element 44, and a gas-guiding cylinder 45; the filter component 6 includes a filter cavity 61, a gas-guiding head 62, an air filter element 63, and a screen layer 64. The top of the box body 1 is butt-connected with a gas-guiding cylinder 45 extending into the interior. The bottom of the gas-guiding cylinder 45 is butt-connected with a gas-guiding cavity 41. The gas-guiding ports 42 communicating with each other are evenly distributed on the outer side of the gas-guiding cavity 41. The resistance heating element 44 is fixedly installed inside the gas-guiding cavity 41. The top of the gas-guiding cylinder 45 is butt-connected with a filter cavity 61 through a gas-guiding head 62. The rear end of the filter cavity 61 is communicated with the output end of the air-blowing component 7. The air filter element 63 and the screen layer 64 are fixedly installed inside the filter cavity 61 respectively.

[0033] After the medicines are placed, the air-blowing operation can be carried out, and the resistance heating element 44 is started synchronously to heat the air. And while blowing the air, it is shunted through the shunt tube 81. The shunted air is unheated, and the unheated air enters the hollow placement tube 51. The heated air is first filtered through the air filter element 63 and the screen layer 64 in the filter cavity 61 and then enters the heating area, and finally enters the interior of the box body 1 to realize the drying operation of the medicines. The unheated air continuously cools the hollow placement tube 51, avoiding the situation that the hollow placement tube 51 has too high heat due to the long-term operation of the oven.

[0038] In the present embodiment, the cooling type placement assembly 5 further includes a connector 53, an air guide sub-tube 54, a docking tube 55, and a footrest 56. The bottom of the air outlet main tube 57 and the air inlet main tube 52 are both fixedly installed with footrests 56, and the footrests 56 are fixedly installed on the inner wall of the box body 1.

[0040] During this period, air first enters the interior through the air guide sub-tube 54 at the air inlet main tube 52, and after diversion, it is discharged through the air guide sub-tube 54 on the air outlet main tube 57.

The flow splitting pipe 81 is communicated with the west receiving pipe 82. At that time, part of the air on the path will enter the flow splitting pipe 81 and finally enter the air guiding auxiliary pipe 54 on the corresponding intake main pipe 52 through the flow splitting pipe 81, thereby completing the continuous cooling of the hollow placement pipe 51.
