Description

Technical Field

[0001] This utility model belongs to the field of container cleaning technology, and more specifically, relates to an acid steam cleaning device. Background Technology

[0002] Currently, when cleaning containers such as pipettes, test tubes, and digestion vessels used in laboratory heavy metal analysis, existing laboratory cleaning methods typically involve immersing the container in a single cylindrical tank filled with an acidic solution, such as nitric acid, for an extended period. This allows residual heavy metals on the container to effectively flow into the acid solution, thus removing them and preventing interference with subsequent analytical experiments. However, directly immersing the container in the acid solution during cleaning can lead to significant acid loss as some of the acid is carried along with the container during removal. Furthermore, direct immersion in acid can result in secondary contamination by heavy metals flowing into the acid solution, necessitating frequent acid replacements to avoid further contamination and causing unnecessary resource waste. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an acid vapor cleaning device. This solves the problem mentioned in the background art where, when containers are directly immersed in an acid solution for cleaning, some acid solution is easily carried along with the containers during the removal process, resulting in a significant loss of acid solution. Furthermore, direct immersion in the acid solution can easily lead to secondary contamination by heavy metals flowing into the acid solution, requiring frequent replacement of the acid solution to avoid contamination and causing unnecessary waste of resources.

[0004] To achieve the above objectives, this utility model provides an acid vapor cleaning device, which includes:

[0005] Heated chassis;

[0006] The cylinder body, the bottom of which is located on top of the heating base;

[0007] A separator plate is disposed inside the cylinder body. A first cavity for placing a container to be cleaned is provided between the separator plate and the top of the cylinder body, and a second cavity for placing an acid solution is provided between the separator plate and the bottom of the cylinder body. Multiple through holes are distributed on the separator plate.

[0008] A support frame assembly is disposed on top of the partition plate and is used to support the container to be cleaned;

[0009] A cover is disposed at the top opening of the cylinder body.

[0010] Preferably, the support frame assembly includes multiple tubes, the sidewalls and tops of which are provided with multiple holes, the bottom end of which is connected to the through hole, and the top end of which is used to be inserted into the container to be cleaned.

[0011] Preferably, the multiple tubes are divided into three parts. The first part of the tube has multiple branch tubes distributed from top to bottom on its side wall. The branch tubes are inclined and are used to insert test tubes or volumetric flasks to be cleaned. The second part of the tube has an annular clamp connected to its side wall. The clamp is used to hold vertically placed pipettes to be cleaned. The third part of the tube has its main body used to insert into a digestion vessel to be cleaned.

[0012] Preferably, the side of the cover that covers the top opening of the cylinder is tapered.

[0013] Preferably, the acid steam cleaning device further includes:

[0014] A temperature sensor, wherein the temperature sensor is disposed inside the cylinder block;

[0015] The control unit is electrically connected to the temperature sensor and the heating chassis. The control unit is set with a temperature threshold. The control unit can adjust the heating chassis according to the temperature data fed back by the temperature sensor to control the temperature inside the cylinder to be maintained at the set temperature threshold.

[0016] Preferably, the temperature threshold is 150°C.

[0017] Preferably, the cover is hinged to the cylinder.

[0018] Preferably, the side wall of the second cavity is provided with a mounting hole, and the acid steam cleaning device further includes an output pipe and a valve, one end of the output pipe passing through the mounting hole, and the valve being disposed on the output pipe.

[0019] Preferably, the acid steam cleaning device includes multiple supports, which are disposed on the inner bottom surface of the cylinder body. The bottom of the partition plate is attached to the multiple supports, and the edge of the partition plate is attached to the inner side of the cylinder body.

[0020] This invention provides an acid vapor cleaning device with the following advantages: The cylinder of the acid vapor cleaning device is mounted on a heating base. A dividing plate separates the first chamber for placing the container to be cleaned and the second chamber for placing the acid solution. A support frame is mounted on top of the dividing plate to support the container to be cleaned. During the cleaning process, the heating base is controlled to heat the cylinder. As the temperature rises, the acid solution in the second chamber generates acid vapor. The acid vapor enters the first chamber through multiple through holes. At this time, the acid vapor comes into contact with the container to be cleaned, forming an acid solution on the surface of the container. The heavy metals remaining on the container can effectively flow into the acid solution, thereby effectively removing the heavy metals remaining on the container. As the acid vapor is continuously generated, the acid solution on the surface of the container will flow back into the second chamber. This acid vapor cleaning device uses acid vapor to replace the original process of direct immersion in acid solution, preventing secondary contamination of the container by heavy metals flowing into the acid solution, saving acid consumption. Furthermore, when the cleaning is finished, the acid solution on the container can drip back into the second chamber, avoiding the container carrying acid solution when it is removed, thus preventing a large loss of acid solution.

[0031] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0032] like Figure 1 and Figure 2 As shown, this utility model provides an acid vapor cleaning device, which includes:

[0033] Heated chassis 1;

[0034] Cylinder 2, the bottom of cylinder 2 is set on top of heating base 1;

[0035] The separator 3 is located inside the cylinder 2. A first cavity 4 for placing the container to be cleaned is provided between the separator 3 and the top of the cylinder 2. A second cavity 5 for placing the acid solution is provided between the separator 3 and the bottom of the cylinder 2. Multiple through holes 6 are distributed on the separator 4.

[0036] The support frame assembly is located on top of the partition plate 3 and is used to support the container to be cleaned.

[0037] Cover 12 is located at the top opening of cylinder 2.

[0038] Specifically, to address the issues of containers being easily contaminated with acid solution during cleaning by direct immersion in the solution, resulting in significant acid loss and secondary contamination from heavy metals flowing into the solution, necessitating frequent solution replacements and resource waste, this invention provides an acid vapor cleaning device. The device comprises a cylinder 2 mounted on a heating base 1, a dividing plate 3 separating a first chamber 4 for holding the container to be cleaned and a second chamber 5 for holding the acid solution, and a support frame assembly on top of the dividing plate 3 for supporting the container. During the cleaning process, the heating base 1 heats the cylinder 2, and the acid solution in the second chamber 5 is released into the container. As the temperature rises, acid vapor is generated. The acid vapor enters the first chamber 4 through multiple through holes 6. At this time, the acid vapor comes into contact with the container to be cleaned, forming an acid solution on the surface of the container. The heavy metals remaining on the container can effectively flow into the acid solution, thereby effectively removing the heavy metals remaining on the container. During the continuous generation of acid vapor, the acid solution on the surface of the container will flow back into the second chamber 5. This acid vapor cleaning device uses acid vapor to replace the original process of direct immersion in acid solution, preventing the container from being secondary contaminated by heavy metals flowing into the acid solution, saving acid consumption. Furthermore, when the cleaning is finished, the acid solution on the container can drip back into the second chamber 5, which can prevent the container from carrying acid solution when it is removed, avoiding a large loss of acid solution.

[0039] Preferably, the support frame assembly includes multiple tubes 7, with multiple holes 8 distributed on the sidewalls and top of the tubes 7, the bottom end of the tubes 7 being connected to the through hole 6, and the top end of the tubes 7 being used to insert into the container to be cleaned.

[0040] Specifically, to address the problem that existing tanks lack internal lining supports, resulting in disorganized containers such as pipettes, test tubes, and digestion vessels, making it inconvenient to locate the required containers and prone to collision damage, this application designs a support frame assembly inside the tank 2. The support frame assembly includes multiple tubes 7, each with a plug at its bottom end that can be inserted into a through hole 6. Multiple tubes 7 can be arranged inside the tank 2, and containers can be neatly inverted onto the tubes 7 according to their type, making them easy to handle and less prone to collision. At the same time, multiple holes 8 distributed on the tubes 7 can evenly disperse acid vapor, allowing the inside and outside of the containers to quickly come into contact with the acid vapor, thus improving the container cleaning efficiency.

[0041] like Figures 4-6 As shown, preferably, the multiple tubes 7 are divided into three parts. The sidewall of the first part of the tube 7 has multiple branch tubes 71 distributed from top to bottom. The branch tubes 71 are inclined and are used to insert test tubes or volumetric flasks to be cleaned. The sidewall of the second part of the tube 7 is connected to an annular clamp 72, which is used to clamp the vertically arranged pipette to be cleaned. The body of the third part of the tube 7 is used to insert into the digestion vessel to be cleaned.

[0042] Specifically, containers are installed on the first part of the tube 7, the second part of the tube 7, and the third part of the tube 7 according to their manufacturing categories, so as to support different types of containers.

[0043] Preferably, the side of the cover 12 that covers the top opening of the cylinder 2 is a conical surface.

[0044] Specifically, to address the problem that existing caps are flat-bottomed and easily accumulate acid droplets, causing acid droplets to splash out when the cap is opened, posing a safety hazard, this application designs one side of the cap 12 as a conical surface. The conical surface is less likely to form a large number of acid droplets at the opening, ensuring safety when opening the cap.

[0045] Preferably, the acid steam cleaning device further includes:

[0046] Temperature sensor, the temperature sensor is located inside the cylinder block;

[0047] The control unit is electrically connected to the temperature sensor and the heating chassis 1. The control unit is set with a temperature threshold. The control unit can adjust the heating chassis according to the temperature data fed back by the temperature sensor in order to control the temperature inside the cylinder to be maintained at the set temperature threshold.

[0048] Specifically, the temperature threshold is 150℃, and the control program of the control unit is based on existing technology. Through the detection of the temperature sensor and the control of the control unit, the acid evaporation time can be controlled at a constant temperature, and the temperature can reach 150℃, shortening the processing time, achieving precise control, and improving the automation process.

[0049] like Figure 3 As shown, preferably, the cover 12 is hinged to the cylinder 2.

[0050] Specifically, to address the problem that existing covers require inverting to prevent one side from contacting other objects when removed from the top opening of the cylinder, which results in a heavy and cumbersome operation, this application sets the cover 12 and the cylinder 2 to a hinged connection. When the cover 12 is opened, it can be directly flipped to one side, which is very convenient and reduces the steps of picking up and inverting the cover 12.

[0051] Preferably, the side wall of the second cavity 5 is provided with an installation hole, and the acid steam cleaning device also includes an output pipe 10 and a valve. One end of the output pipe 10 passes through the installation hole, and the valve is provided on the output pipe 10.

[0052] Specifically, the output pipe 10 is used to discharge the acid solution.

[0053] Preferably, the acid steam cleaning device includes multiple supports 11, which are disposed on the inner bottom surface of the cylinder 2. The bottom of the partition plate 3 is attached to the multiple supports 11, and the edge of the partition plate 3 is attached to the inner side of the cylinder 2.

[0054] Specifically, support 11 is used to support the divider plate 3.

[0055] In summary, the acid vapor cleaning device of this application, when implemented, first injects the acid solution into the second chamber 5 through the top opening of the cylinder 2, and then neatly inverts the containers according to their type onto multiple tubes 7. During the cleaning process, the heating base 1 is controlled to heat the cylinder 2, and the acid solution in the second chamber 5 will generate acid vapor as the temperature rises. The acid vapor enters the first chamber 4 through multiple through holes 6. At this time, the acid vapor will come into contact with the container to be cleaned, forming an acid solution on the surface of the container. At this time, the heavy metals remaining on the container can effectively flow into the acid solution, thereby effectively removing the heavy metals remaining on the container. During the continuous generation of acid vapor, the acid solution on the surface of the container will flow back into the second chamber 5. This acid vapor cleaning device uses acid vapor to replace the original process of direct immersion in acid solution, preventing the container from being secondary contaminated by heavy metals flowing into the acid solution, saving acid consumption, and when the cleaning is finished, the acid solution on the container can drip back into the second chamber 5, which can avoid the container carrying acid solution when it is taken out, avoiding a large loss of acid solution.

[0056] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
