Description

Technical Field

[0001] This utility model relates to the field of experimental instrument drying technology, and to an airflow dryer, particularly to an airflow dryer for glass instruments. Background Art

[0002] An airflow dryer, also known as a glassware airflow dryer, is a device specifically designed for laboratory and research environments to rapidly dry glassware such as beakers, test tubes, and petri dishes. It uses a high-temperature airflow to remove moisture from the surface and interior of the equipment, ensuring the accuracy and reliability of experiments.

[0003] Current airflow dryers have some limitations and shortcomings in use. For example, because cleaning fluid remains on the glassware after cleaning, when the glassware is placed on the air outlet pipe of the airflow dryer, the residual cleaning fluid will drip down. When the residual cleaning fluid comes into contact with the top of the airflow dryer, it may cause splashing to varying degrees, thus polluting the environment around the airflow dryer. At the same time, current airflow dryers only have a collection tank. The residual cleaning fluid cannot be discharged after entering the collection tank and can only be dried by the temperature of the airflow dryer itself. After long-term use, scale may form in the collection tank, which is difficult to clean and thus causes pollution of the airflow dryer.

[0004] A glass instrument airflow dryer is disclosed in utility model application number CN202220456661.5 and publication number CN218210355U. The dryer includes a body with multiple drying tubes. A drying mechanism for wiping moisture off glass instruments is located at the center of the top of the body. The drying mechanism includes a drying rod and a drying block. One end of the drying block has a blind hole and is fitted onto the drying rod. During use, residual cleaning fluid inside the glass instruments still drips down, which may cause splashing to varying degrees, thus polluting the environment around the airflow dryer. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention utilizes an annular collecting trough, a liquid outlet, a liquid outlet pipe, and a waste liquid recovery tank to recover residual cleaning fluid after cleaning glassware. Simultaneously, a shielding cover on the outside of the annular collecting trough prevents residual cleaning fluid from splashing into the environment surrounding the airflow dryer when dripping. In practical use, the cleaned glassware is hung on the air outlet duct.

DETAILED DESCRIPTION

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example:

[0033] like Figures 1 to 2 As shown, in order to solve the above problems, this embodiment discloses an airflow dryer, including a dryer body 10 and a disc-shaped top cover 20. The disc-shaped top cover 20 is disposed on the top of the dryer body 10 and is detachably connected to the top of the dryer body 10. The middle part of the disc-shaped top cover 20 is provided with a plurality of mounting inclined surfaces 200 arranged in a circular array around the center of the disc-shaped top cover 20. Each mounting inclined surface 200 is provided with an air outlet pipe 201. One end of the air outlet pipe 201 passes through the disc-shaped top cover 20 and communicates with the dryer body 10.

[0034] The disc-shaped top cover 20 is provided with an annular collecting groove 202, which is located outside a plurality of mounting inclined surfaces 200 and is configured to cooperate with the mounting inclined surfaces 200. The disc-shaped top cover 20 is provided with a shield 203, which is located outside the annular collecting groove 202 and is fixedly connected to the disc-shaped top cover 20.

[0035] One end of the annular collecting tank 202 is provided with a liquid outlet 204, and a waste liquid recovery tank 205 is provided below the liquid outlet 204. The liquid outlet 204 and the waste liquid recovery tank 205 are connected by a liquid outlet pipe 206. The cleaning liquid remaining on the glass instrument can flow into the annular collecting tank 202 through the installation slope 200, and then flow into the waste liquid recovery tank 205 through the liquid outlet 204 and the liquid outlet pipe 206.

[0036] This invention utilizes an annular collecting trough 202, a liquid outlet 204, a liquid outlet pipe 206, and a waste liquid recovery tank 205 to recover residual cleaning fluid after cleaning glassware. Simultaneously, a shield 203 is installed outside the annular collecting trough 202 to prevent residual cleaning fluid from splashing into the surrounding environment of the airflow dryer when dripping. In practical use, the cleaned glassware is hung on the air outlet duct 201. Residual cleaning fluid drips onto the mounting slope 200. The splashed portion of the cleaning fluid is blocked by the shield 203, allowing the cleaning fluid to flow from the mounting slope 200 and the inner wall of the shield 203 into the annular collecting trough 202, and then into the waste liquid recovery tank 205 through the liquid outlet 204 and the liquid outlet pipe 206 for recovery. Compared with traditional airflow dryers, this invention can not only effectively reduce the amount of cleaning liquid on the airflow dryer, but also effectively prevent the cleaning liquid from splashing into the surrounding environment when it drips. This solves the problem that when the cleaning liquid remaining inside the glassware drips during the use of current airflow dryers, it may cause varying degrees of splashing, thus polluting the environment around the airflow dryer.

[0037] It should be noted that the end of the annular collecting trough 202 located at the outlet 204 is lower than the end of the annular collecting trough 202 furthest from the outlet 204. That is, there is a height difference between the end of the annular collecting trough 202 located at the outlet 204 and the end of the annular collecting trough 202 furthest from the outlet 204, and the height is a gradually changing structure. The outlet 204 is located at the lowest point, so that the cleaning liquid collected at the end of the annular collecting trough 202 furthest from the outlet 204 can flow from high to low, which facilitates the outflow of the cleaning liquid in the annular collecting trough 202.

[0038] like Figure 2 As shown, in order to facilitate the flow of cleaning fluid on the inner wall of the shield 203 into the annular collection groove 202, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the shield 203 includes a conical section 207 and an annular section 208. The conical section 207 is disposed on the disc-shaped top cover 20 and is fixedly connected to the disc-shaped top cover 20. The annular section 208 is disposed on the top of the conical section 207 and is fixedly connected to the conical section 207.

[0039] It should be noted that the smaller diameter end of the conical segment 207 is mounted on the disc-shaped top cover 20 and is fixedly connected to the disc-shaped top cover 20, while the annular segment 208 is fixedly connected to the larger diameter end of the conical segment 207.

[0040] When in use, the conical section 207 allows the cleaning fluid to flow more easily into the annular collection tank 202.

The end of the air outlet pipe body 209 that passes through the disc-shaped top cover 20 is connected to the dryer body 10. The air outlet head 210 is located at the other end of the air outlet pipe body 209 and is detachably connected to the air outlet pipe body 209 by threads. The air outlet head 210 is provided with several air outlet holes.

The bottom of the disc-shaped top cover 20 is fitted onto the outer side of the top of the upper shell 100 and is detachably connected to the top of the upper shell 100.

[0043] The bottom of the upper housing 100 and the top of the lower housing 101, and the bottom of the disc-shaped top cover 20 and the top of the upper housing 100 can be detachably connected by bolts or threads, or other detachable connection methods that can achieve the function of this utility model can be used in the prior art.

[0044] In use, the disc-shaped top cover 20 is detachably connected to the upper housing 100, which facilitates the assembly and disassembly of the disc-shaped top cover 20 and the upper housing 100, and also facilitates the assembly and disassembly of the heating component 103; the upper housing 100 is detachably connected to the lower housing 101, which facilitates the assembly and disassembly of the upper housing 100 and the lower housing 101, and also facilitates the assembly and disassembly of the air supply component 102; the filter component 104 is detachably connected to the lower housing 101, which facilitates the assembly and disassembly of the filter component 104.

[0045] like Figures 6 to 7 As shown, in order to facilitate heating air, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the heating assembly 103 includes a mounting ring 105 and a plurality of electric heating elements 106 disposed on the mounting ring 105. The mounting ring 105 is provided with a pair of limiting blocks 107. The inner side wall of the top of the upper housing 100 is provided with a limiting slot 108 that cooperates with the pair of limiting blocks 107. The limiting blocks 107 are inserted into the limiting slots 108 and are interference-fitted.

[0046] The electric heating element 106 can be an electric heating rod or an electric heating wire as used in the prior art.

[0047] During use, the air entering the upper housing 100 can be heated by several electric heating elements 106 to form hot air, which facilitates the drying of glass instruments.

[0048] like Figure 8 As shown, to facilitate air filtration, this embodiment is modified from the above embodiment. The difference from the above embodiment is that the filter assembly 104 includes a first filter 109, a second filter 110, and a third filter 111. The bottom of the lower housing 101 is provided with an installation window. The first filter 109 is located at the bottom of the installation window and at the bottom of the lower housing 101. The first filter 109 is detachably connected to the lower housing 101 by bolts. The third filter 111 is located at the top of the installation window and inside the lower housing 101.

Then, it enters the upper housing 100 through the air supply assembly 102. The air is heated by the heating assembly 103, and the heated air enters the glass instrument to be dried through the air outlet duct 209, the air outlet head 210 and the air outlet hole, thereby completing the drying of the glass instrument.

[0053] Working principle of this utility model:

[0054] This invention utilizes an annular collecting trough 202, a liquid outlet 204, a liquid outlet pipe 206, and a waste liquid recovery tank 205 to recover residual cleaning fluid after cleaning glassware. Simultaneously, a shield 203 is installed outside the annular collecting trough 202 to prevent residual cleaning fluid from splashing into the environment surrounding the airflow dryer when dripping. In practical use, the cleaned glassware is hung on the air outlet duct 201. Residual cleaning fluid drips onto the mounting slope 200. The splashed portion of the cleaning fluid is blocked by the shield 203, allowing the cleaning fluid to flow from the mounting slope 200 and the inner wall of the shield 203 into the annular collecting trough 202, and then into the waste liquid recovery tank 205 through the liquid outlet 204 and the liquid outlet pipe 206 for recovery. Compared to traditional airflow dryers, this invention not only effectively reduces the amount of cleaning fluid on the airflow dryer but also effectively prevents cleaning fluid from splashing into the environment surrounding the airflow dryer when dripping.

[0055] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent.
