Description

Technical Field

[0001] This invention relates to the field of pickling technology, and more particularly to a pickling apparatus for laboratory glassware. Background Technology

[0002] Laboratory test tubes, due to contact with various reagents and samples, are prone to developing stubborn residues on their inner and outer walls. Incomplete cleaning can affect experimental accuracy and lead to cross-contamination. Currently, a common cleaning method is "acid / alkali tank immersion + manual rinsing." The acid / alkali rinsing step after immersion involves manually handling, transferring, rinsing, and brushing test tubes with residual acid / alkali. This requires wearing gloves, goggles, and other protective equipment, and involves personnel in contact with acid / alkali for extended periods. The entire process includes multiple manual steps, from acid / alkali washing and brushing to repeated rinsing, resulting in low efficiency and high labor intensity. Some existing automated cleaning equipment mainly uses cleaning solutions to rinse test tubes, which can easily remove some common residues. However, for some stubborn residues, immersion is necessary for removal. Existing automated cleaning equipment cannot effectively perform immersion operations. Furthermore, in current technologies, drying test tubes requires transferring the cleaned test tubes to drying equipment, which is time-consuming and labor-intensive, making it difficult to guarantee the cleaning quality of large batches of test tubes. Summary of the Invention

[0003] To overcome the disadvantages of test tube immersion acid washing, which requires manual contact with acidic solutions, is inconvenient to clean, and is time-consuming and labor-intensive to dry, this invention provides a laboratory glassware acid washing device.

[0004] The technical solution is as follows: A laboratory glassware acid washing device, comprising a box body and a collection tank installed inside the box body; a cleaning cylinder is installed inside the box body, located above the collection tank; a cover plate is provided on the box body to isolate the cleaning cylinder; a collection pipe is installed inside the box body, connecting the cleaning cylinder and the collection tank; it also includes an air inlet pipe; an airflow plate is installed at the bottom of the cleaning cylinder, connected to the air inlet pipe; several air outlet pipes are installed and connected to each airflow plate; several air holes are provided at the top of each air outlet pipe; an inlet plate is placed on top of the airflow plate, connected to an inlet pipe; an air outlet pipe of equal volume to the air outlet pipe is installed and connected to the inlet plate. The liquid outlet pipe surrounds the surface of the gas outlet pipe; a mounting bracket is detachably connected to the liquid inlet plate, and the mounting bracket has a liquid outlet groove; the mounting bracket has through holes of the same number as the gas outlet pipe, through which the gas outlet pipe passes; the surface of the mounting bracket has elastic sealing rings of the same number as the through holes, and the elastic sealing rings surround the through holes; the mounting bracket has a stop block of the same number as the gas outlet pipe, through which the gas outlet pipe passes, and after the stop block blocks the through holes, it seals the inside of the inverted test tube with the elastic sealing rings; an elastic element is symmetrically installed at the lower part of each stop block, and the other end of the elastic element is connected to the mounting bracket; a plug is installed at the upper part of each liquid outlet pipe.

[0005] Furthermore, a spray plate is installed inside the cleaning tank to rinse the outer surface of the test tubes.

[0006] Furthermore, the elastic sealing rings come in different sizes.

[0007] Furthermore, the mounting bracket has long handles on its surface.

[0008] Furthermore, the pores are micropores.

[0009] Furthermore, the stop block is frustum-shaped.

[0010] Furthermore, the top of the long handle is equipped with an anti-slip pad.

[0011] Furthermore, it also includes limit blocks; a limit block is provided above each plug.

[0012] Furthermore, both the air outlet pipe and the liquid outlet pipe are detachable.

[0013] Furthermore, the elastic sealing ring is made of neoprene rubber, EPDM rubber, or fluororubber.

[0014] The beneficial effects of this invention are as follows: This invention achieves a simultaneous cleaning design of its inner and outer walls (internal acid / alkali immersion and rinsing, external spray cleaning), which greatly improves the cleaning efficiency and effect, ensures no residue, and realizes automated control of the whole process, reducing manual operation steps and labor intensity. At the same time, it separates the test tubes that need to be cleaned, avoiding large-scale accumulation and collision that could damage the test tubes, thus improving the overall efficiency of experimental preparation.

[0015] Furthermore, continuous ventilation after cleaning can quickly dry the inner wall of the test tubes, avoiding the impact of water stains. There is no need for manual transfer of the test tubes to be dried to the drying equipment, which is time-consuming and laborious. The whole process is highly automated, effectively shortening the cleaning cycle and thus ensuring the cleaning quality of a large number of test tubes in the laboratory. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example A laboratory glassware acid washing apparatus, such as Figures 1-7 As shown, it includes a box body 1 and a collection tank 2; the collection tank 2 is installed on the box body 1; acidic / alkaline solutions and cleaning water are collected through the collection tank 2; a cleaning cylinder 3 is installed inside the box body 1, and the cleaning cylinder 3 is located above the collection tank 2; a cover plate 4 is provided on the box body 1 to isolate the cleaning cylinder 3; a collection pipe 5 is installed inside the box body 1, and the collection pipe 5 connects the cleaning cylinder 3 and the collection tank 2; It also includes an air inlet pipe 101, an airflow plate 102, an air outlet pipe 103, a mounting bracket 104, a baffle 105, a liquid inlet pipe 201, a liquid inlet plate 202, a liquid outlet pipe 203, and a plug 204; an airflow plate 102 is installed at the bottom of the cleaning tank 3, the airflow plate 102 is connected to the air inlet pipe 101, and each airflow plate 102 is hollow inside; several air outlet pipes 103 are installed and connected to each airflow plate 102; each The top of each vent pipe 103 is provided with several vent holes 10301; an inlet plate 202 is placed on the upper part of the airflow plate 102, and the inlet plate 202 is connected to the inlet pipe 201; an outlet pipe 203 of the same number as the vent pipe 103 is installed and connected on the inlet plate 202, and the outlet pipe 203 surrounds the surface of the vent pipe 103 and is concentrically arranged with the vent pipe 103; each outlet pipe 203 is sleeved on the vent pipe 103, which is beneficial for the test tube 6 The inner wall is soaked, cleaned, and dried. A mounting bracket 104 is detachably connected to the liquid inlet plate 202. The mounting bracket 104 has an outlet groove 10401 for discharging its internal liquid. The mounting bracket 104 has through holes of the same number as the vent pipe 103, through which the vent pipe 103 passes. The surface of the mounting bracket 104 has elastic sealing rings 7 of the same number as the through holes, and the elastic sealing rings 7 surround the through holes. The mounting bracket 104 has a stop block 105 of the same number as the vent pipe 103, through which the vent pipe 103 passes. After the stop block 105 blocks the through holes, it seals the inverted test tube 6 with the elastic sealing rings 7. Each stop block 105 has a symmetrical elastic element 10501 installed at the bottom, and the other end of the elastic element 10501 is connected to the mounting bracket 104. The elastic element 10501 is a spring telescopic rod. Each outlet pipe 203 has a plug 204 installed at the top.

[0020] The cleaning tank 3 is equipped with a spray plate 9 for rinsing the outer surface of the test tube 6, which can also clean the outer wall of the test tube 6, thus improving the cleaning efficiency.

[0021] The elastic sealing rings 7 come in different sizes to achieve a sealing and fixing effect on test tubes 6 of different sizes, thus improving the applicability of the equipment. The mounting bracket 104 is equipped with a long handle 8 on its surface; this allows operators to remove the mounting bracket 104 by pulling on the long handle 8 without having to go deep into the cleaning tank 3, improving safety during use.

[0022] The vent 10301 is a micro-vent 10301 to prevent acid / alkali solutions from entering the vent 10301. The stop block 105 is frustoconical, and its movement involves almost no friction with the mounting bracket 104, making the lifting and lowering of the stop block 105 faster. The top of the long handle 8 is equipped with an anti-slip pad to prevent slippage when picking up or placing the mounting bracket 104, thus preventing damage to the test tube 6. It also includes a limit block 205; a limit block 205 is provided above each plug 204 to prevent the plug 204 from being impacted and detached from the outlet pipe 203 during the liquid injection process.

[0023] Both the vent pipe 103 and the liquid outlet pipe 203 are detachable. The length can be changed to match the length of the test tube 6 to be cleaned, so that the top of the vent pipe 103 and the liquid outlet pipe 203 can always contact the inner top of the inverted test tube 6, thereby maximizing the removal of gas from the inside of the test tube 6.

[0024] The elastic sealing ring 7 is made of neoprene rubber, EPDM rubber, or fluororubber.

[0025] In chemistry and biology laboratories, test tubes (6) frequently receive various reagents. Incomplete cleaning can affect the accuracy of subsequent experiments and even cause cross-contamination. Currently, laboratories use a "soaking in acid / alkali tanks + manual rinsing" method to clean test tubes (6). This process involves multiple manual steps, is cumbersome, and cannot be used for cleaning large quantities of test tubes (6). Furthermore, the process requires personnel to remove the test tubes, increasing the risk of injury due to prolonged contact with acid / alkali solutions. Moreover, in chemistry and biology laboratories, the thoroughness of cleaning the inner walls of test tubes (6) and the efficiency of drying after cleaning are crucial for subsequent experiments. Generally, the cleaned test tubes (6) must be manually transferred to drying equipment, which is time-consuming and labor-intensive. The process lacks automation, and operational efficiency and cleaning effectiveness are greatly affected by human factors. Additionally, because each step is independent and time-consuming, the overall cleaning cycle is long, making it difficult to meet the cleaning quality requirements for large quantities of test tubes (6) in laboratories.

[0026] To address the aforementioned issues, test tubes 6 are first placed on mounting bracket 104 outside the housing 1. The elastic sealing rings 7 mounted on mounting bracket 104 are arranged in sections, with different diameters of elastic sealing rings 7 installed in different areas. For test tubes 6 with different diameters, different areas can be used. The test tubes 6 are inverted and inserted into the elastic sealing rings 7. The elastic force of the elastic sealing rings 7 can be used to fix the test tubes 6 and seal them, preventing solution leakage during acid / alkali immersion. Depending on the liquid environment they will be exposed to, the elastic sealing rings 7 can be made of rubber with strong acid and alkali resistance, such as chloroprene rubber, EPDM rubber, or fluororubber.

[0027] Then, by pulling up the long handle 8, the mounting bracket 104 is placed into the cleaning tank 3, allowing the outlet pipes 203 to pass through the holes in the center of each elastic sealing ring 7 on the mounting bracket 104, thus placing the mounting bracket 104 on the inlet plate 202. Then, the cover plate 4 is closed, and the pump is started to introduce acid / alkali solution through the inlet pipe 201. The acid / alkali solution enters the outlet pipe 203 through the inlet plate 202. Then, the plug 204 is lifted, and the acid solution flows into the test tube 6. Simultaneously, the external air pump is started to draw in gas, and the negative pressure is conducted through the air inlet pipe 101 to the airflow plate 102, and then through the air hole 10301 of the outlet pipe 103, such as... Figure 5As shown, air is drawn from the top of the inverted test tube 6, allowing the acid to rise and fill the entire interior of the test tube 6. When the acid level is about to reach a certain position, the air is drawn off, but acid is continued to be injected to fill the remaining space in the test tube 6. At the same time, the external liquid pump is turned on, and distilled water is sprayed through the spray plate 9 to clean the outer wall of the test tube 6. After the test tube 6 has been soaked in acid / alkali solution for a predetermined time, gas is introduced into the vent pipe 103, which increases the pressure inside the test tube 6 and pushes the stop block 105 downward. At this time, the elastic element 10501 will be compressed, and the stop block 105... Moving downwards, the acidic solution flows from the gap into the mounting bracket 104, then flows out through the outlet tank 10401 into the cleaning tank 3, and then collects in the collection tank 2 through the collection pipe 5. At this time, cleaning water is introduced through the inlet pipe 201 to rinse the residual acid / alkali solution on the inner wall of the test tube 6, and then collects in the collection tank 2 as well, thereby achieving the purpose of soaking and cleaning the inner wall of the test tube 6. After cleaning, the gas sprayed from the vent pipe 103 can dry the inner wall of the test tube 6 without moving the test tube 6 to another place, preventing residual water stains from affecting the next experiment.
