Description

Technical Field

[0001] The invention belongs to the technical field of laboratory instrument drying, and in particular relates to a drip rack capable of rapid drying with a trace amount of warm air. Background Art

[0002] With the increasing development of scientific experiments, chemical analysis and biological experiments, a large number of laboratory utensils used in laboratories need to be dried quickly and thoroughly after use to ensure the accuracy and safety of the next experiment. If the utensils are not completely dried, there may be residual moisture or chemical reagents. These residual substances will interfere with the experimental results in subsequent experiments, affecting the accuracy and reliability of the experiments. If there is moisture or other solution residue in the utensils, it may dilute or contaminate the reagents used in the subsequent use, affecting the experimental results, and may even cause the experiment to fail. Some chemical reactions are extremely sensitive to moisture. The presence of moisture may change the reaction conditions or results, resulting in incorrect experimental data. Multiple utensils need to be used frequently during the experiment. If the utensils are not dried in time, it may cause a long waiting time, affecting the progress of the overall experiment. The rapid drying of the utensils enables the experimenters to quickly prepare the required utensils and carry out the next experiment, saving the time of repeated cleaning and drying. Undried utensils are prone to breed bacteria and mold in the presence of residual moisture, especially in utensils such as culture dishes and test tubes that come into contact with biological samples. This will not only affect the experimental results, but also pose a threat to the health of the experimenters. Some experimental materials are sensitive to moisture, and undried utensils may cause the materials to deteriorate or other adverse reactions. Long-term residual moisture, especially in metal utensils, may cause rust and corrosion, shortening the service life of the utensils. Mineral components in water (such as calcium, magnesium, etc.) will leave scale on the surface of the utensils, affecting the use and cleaning of the utensils, and may even cause damage to the utensils.

[0003] Traditional drip racks usually rely on natural air flow or ordinary drain racks, but have low drying efficiency and cannot meet the time requirements during the washing operation and the requirements for utensil stocking and recycling. Summary of the invention

[0004] In view of this, the present invention provides a drip rack that can quickly dry with a small amount of warm air, which can solve the problem that traditional drip racks usually rely on natural air flow or ordinary drainage racks, but have low drying efficiency and cannot meet the time requirements during the washing operation and the requirements for utensil stocking and recycling.

[0005] The present invention is achieved in that:

[0006] The present invention provides a drip rack capable of rapid drying with a trace amount of warm air, wherein the drip rack comprises a punching rod, a PP rack cavity, a side drainage pipe, a detachable back plate, a filter rack, an embedded magnetic attraction structure and a breeze heating component, wherein the punching rod comprises a plurality of holes, which are respectively plugged and fixed to the surface of the PP rack cavity; the side of the PP rack cavity away from the punching rod is provided with the side drainage pipe, and the detachable back plate is movably connected to the PP rack cavity; the bottom of the PP rack cavity is provided with an inclined drainage groove on the side corresponding to the punching rod, the side drainage pipe is provided on one side of the inclined drainage groove, and the side drainage pipe The channel is used to discharge the water dripping from the laboratory instrument hanging on the punching rod; the breeze heating component is arranged at the bottom of the pp frame cavity, and its cavity position is connected with the breeze heating component through the breeze heating component, which is used to transfer the hot air generated by the breeze heating component to the cavity of the pp frame cavity, enter the inner wall of the laboratory vessel hanging on the punching rod through the punching rod and dry the laboratory vessel; the breeze heating component is detachably connected to the bottom of the pp frame cavity through the embedded magnetic attraction structure; the filter rack is arranged on the side wall of the breeze heating component;

[0007] The side wall of the punching rod is provided with square holes, and the square holes include a plurality of holes, which are arranged around the punching rod, so that the airflow output from the punching rod to the laboratory vessel surrounds the inner wall of the laboratory vessel to quickly dry each part of the inner wall; the direction of the airflow from the punching rod is at an angle to the normal line of the side wall of the punching rod, and is inclined in a direction away from the corresponding hole.

[0008] On the basis of the above technical solution, the dripping rack capable of rapid drying with a trace amount of warm air of the present invention can also be improved as follows:

[0009] The punching rods include a plurality of punching rods which are inserted on the surface of the PP rack cavity at an angle of 55° and have a hollow structure inside, and are used to allow the wind inside the PP rack cavity to enter the laboratory vessel through the cavity.

[0010] Furthermore, the size of the holes on the side wall of the punching rod is 1.3mm*9mm, and the number of square holes on the side wall of each punching rod is 4-8; the punching rod is made of PP material; the number of the punching rods installed on the surface of the PP frame cavity is between 25-30.

[0011] Furthermore, a circular hole is provided at the top of the punching rod, which cooperates with the multiple square holes on the side wall to form an arc-shaped airflow between the side wall of the suspended laboratory vessel, so that the inner wall of the laboratory vessel in contact with the top wall of the punching rod can also be dried; the diameter of the circular hole at the top is 1.5 mm.

[0012] Furthermore, the cross-sectional width of the punching rod perpendicular to the axis gradually increases along the axis direction from the top to the bottom inserted into the PP rack cavity, so as to ensure the stability of the suspended laboratory vessels.

[0013] Furthermore, an inclined baffle is provided on the side wall of the punching rod, which is used to limit the airflow direction to a certain extent and increase the pressure generated on the inside of the laboratory vessel when the airflow passes through the square hole.

[0014] Furthermore, the embedded magnetic structure includes a magnetic sheet group arranged at the bottom of the PP frame cavity and a corresponding magnetic sheet group arranged at the top of the breeze heating component, each magnetic sheet group includes three magnetic sheets, which are used to realize a detachable connection between the PP frame cavity and the breeze heating component.

[0015] Furthermore, the breeze heating component includes a fan group, a shell and a heating wire. The fan group is arranged inside the shell and includes 1-3 fans, which are used to suck outside air into the shell and transmit it to the inside of the pp frame cavity; the heating wire is arranged between the top of the shell and the fan group, which is used to heat the airflow output by the fan group to the inside of the pp frame cavity, and the heating temperature is lower than 50°C; the filter rack is arranged on the side wall and bottom wall of the shell, and a replaceable polyurethane filter is arranged inside the filter rack, which is used to filter the airflow sucked into the shell by the fan group.

[0016] Furthermore, the detachable back plate is provided with a hook for hanging the drip rack on the upper part of the sink to dry the cleaned laboratory utensils.

[0017] Furthermore, the angle between the direction of the airflow blowing out of the punching rod and the normal line of the side wall of the punching rod is related to the speed of the airflow reaching the inside of the punching rod.

[0018] Compared with the prior art, the beneficial effect of the drip rack that can be quickly dried with a trace amount of warm air provided by the present invention is that: the punching rods are designed to be multiple, and are connected to the surface of the PP frame cavity in an inclined state. The interior of each punching rod is a hollow structure, which is used to transfer the wind inside the cavity to the suspended laboratory vessel through the punching rod. The multiple square holes on the side wall of the punching rod help to evenly distribute the airflow on the inner wall of the laboratory vessel, forming a surrounding airflow, ensuring that each part of the vessel is quickly and effectively dried. An angle is set between the airflow blowing direction of the punching rod and the normal of the side wall, and it is inclined in the direction away from the hole, so that the airflow can evenly cover the entire vessel. The size of the square hole is 1.3mm*9mm, and each punching rod has 4 to 8 square holes, ensuring that the airflow has sufficient pressure for efficient drying.

[0019] The PP frame cavity provides a structure to accommodate multiple perforated rods, ensuring that the airflow is transferred from the breeze heating component to the perforated rods. The design of the cavity also takes into account the smooth and uniform transmission of airflow.

[0020] The bottom of the chamber is equipped with an inclined drain trough, which can effectively guide the water dripping from the laboratory utensils to the side drainage pipe for drainage, avoid water accumulation, and help keep the drying environment dry. The side drainage pipe is mainly used to remove the water dripping from the laboratory utensils hanging on the punch rod, ensuring the dry environment of the drip rack without affecting the drying effect.

[0021] The back plate is movably connected to the PP rack cavity, which can be easily disassembled for cleaning or maintenance. It can also hang the drip rack on the top of the sink through a hook to dry cleaned laboratory utensils.

[0022] The filter rack is equipped with a replaceable polyurethane filter, which is used to filter impurities in the air to ensure that the air inhaled by the fan is clean, so as not to blow dust or impurities onto the laboratory vessels and avoid affecting the cleanliness of the vessels.

[0023] The breeze heating component is connected to the PP frame cavity through an embedded magnetic structure. This detachable design makes the breeze heating component easy to disassemble or maintain. The magnetic sheet group consists of multiple magnetic sheets, which can firmly connect the components to prevent loosening or falling off.

[0024] The breeze heating assembly includes a fan unit, a housing and a heating wire. The fan unit is responsible for sucking outside air into the housing and heating the air through the heating wire to ensure that the air flow temperature remains below 50°C, which is suitable for drying laboratory utensils. The heated air flow is transferred to the utensils through the perforated rod to ensure efficient drying. The heating temperature of the breeze heating assembly is controlled below 50°C to avoid overheating and damage to laboratory utensils. At the same time, the fan unit continuously provides warm air to make the drying process faster and more uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] 1. Heat conduction and heat convection

[0046] Heat conduction: When hot air (mild air) blows onto the surface of the vessel, the heat is transferred through the contact between the air and the surface of the vessel, raising the temperature of the surface of the vessel. When the temperature rises, the moisture on the surface of the vessel begins to absorb heat and turns into water vapor.

[0047] Thermal convection: At the same time, the flow of hot air causes the cold air near the surface to be replaced by hot air, driving the water to evaporate faster. The flow between hot air and water vapor accelerates the removal of moisture, especially at higher temperatures and larger airflows, the evaporation rate will increase significantly.

[0048] 2. Water evaporation

[0049] The core principle of this drying device is to remove moisture from objects through the evaporation process. Evaporation refers to the process in which liquid molecules gain enough energy on the surface and break through the surface tension to enter the air. Since the evaporation of water requires heat, the hot air will transfer heat to the surface of the vessel, causing the moisture to evaporate into water vapor.

[0050] By heating and blowing air, water vapor is removed from the surface of the object, gradually reducing the moisture content on the surface and inside the object.

[0051] 3. The role of airflow

[0052] Enhanced evaporation rate: Airflow (a small amount of warm air) plays a vital role by accelerating the evaporation process. The airflow continuously removes the water vapor produced by evaporation, avoiding the saturation of water vapor during the evaporation process. This can speed up the removal of water and make the drying process more efficient.

[0053] Promote the discharge of water vapor: The strong airflow will discharge the evaporated water vapor out of the system in time, preventing the water vapor from accumulating around the surface of the vessel and causing slow evaporation.

[0054] 4. Temperature control

[0055] Effect of temperature on evaporation: The evaporation rate is closely related to temperature. Higher temperatures will accelerate the movement of water molecules, making them easier to evaporate. Warm air heating equipment controls the temperature and provides warm air to accelerate the evaporation of water on the container.

[0056] Avoid damaging utensils due to excessive temperature: Generally speaking, the temperature control system of the trace warm air drying drip rack will ensure that the temperature does not exceed a safe range, usually around 50°C, to ensure that the heating process is both efficient and does not damage the utensils.

[0057] 5. Moisture emission and air circulation

[0058] Moisture removal is an important part of the drying process. When using warm air, moisture will be carried away and discharged through the drainage system or exhaust duct, which helps to keep the drying environment dry and avoid moisture retention in the equipment, thereby ensuring drying efficiency.

[0059] Air circulation also helps maintain an even temperature inside the unit, ensuring that all moisture on the dishes is effectively evaporated by even airflow.

[0060] Furthermore, in the above technical solution, the angle between the direction of the airflow blowing out of the punching rod 10 and the normal line of the side wall of the punching rod 10 is related to the speed of the airflow reaching the inside of the punching rod 10 .

[0061] In a preferred embodiment of the present invention, the research team combined the Venturi equation and the Helmholtz equation to finally obtain a relationship that is used to define the relationship between the angle between the direction of the airflow of the punching rod 10 and the normal line of the side wall of the punching rod 10 and the airflow velocity, and is mainly used to determine the optimal angle of the air hole according to the gas flow velocity relationship:

[0062] The difference between the angle α between the direction of the airflow of the punch rod 10 and the normal line of the side wall of the punch rod 10 and the angle θ between the fluid output direction and the x-axis is 55°; the direction of the fluid can be determined by the ratio of the velocity components u and v.

[0063] At the same time, under ideal conditions,

[0064]

[0065] This means that ideally, the angle θ between the fluid direction and the x-axis is 45°.

[0066] However, in actual situations, the velocity components u and v of the fluid will be affected by factors such as the rotation and deformation of the fluid particles. According to the Helmholtz velocity decomposition theorem, the velocity of the fluid particles can be decomposed into three parts: translation, rotation and deformation. In two-dimensional plane flow, the velocity components u and v can be expressed as:

[0067]

[0068] u(M0) and v(M0) are the velocity components at the reference point M0;

[0069] and is the linear strain rate of velocity;

[0070] and Related to rotation and angular deformation rates;

[0071] Therefore, the more general form is:

[0072]

[0073] At the same time, according to the principle of the Venturi flowmeter, when the fluid flows through the pipeline, the relationship between the flow rate and the pressure difference can be derived through the Bernoulli equation and the continuity equation.

[0074]

[0075] in:

[0076] P1 and P2 are the pressures at the pipe inlet and throat, respectively;

[0077] v1 and v2 are the flow velocities at the corresponding positions;

[0078] ρ is the fluid density.

[0079] Through the continuity equation:

[0080]

[0081] Where A1 and A2 are the cross-sectional areas of the pipe inlet and throat.

[0082] Combining the above formula, the flow velocity v2 at the throat can be solved:

[0083]

[0084] Where ΔP=P1-P2, is the pressure difference

[0085] Combining the fluid direction and velocity, we can get the comprehensive relationship between the fluid outlet direction, angle and airflow size:

[0086]

[0087] θ is the angle between the fluid direction and the x-axis;

[0088] v is the fluid velocity;

[0089] ΔP is the pressure difference;

[0090] ρ is the fluid density;

[0091] A1 and A2 are the cross-sectional areas of the pipe inlet and throat.

[0092] After calculation, when the flow rate is 5-8m 3 / H, the optimal opening angle is 25-45°.

[0093] Secondly, an inclined baffle is provided on the side wall of the punching rod 10 to produce a Venturi effect. When the restricted flow passes through the reduced flow section, the fluid velocity increases, and the velocity is inversely proportional to the flow section. When the fluid filling the pipeline flows through the throttling device in the pipeline, the fluid will form a local contraction at the throat of the Venturi tube. The velocity of the fluid is increased, and the static pressure is reduced, so that the wind blows downward. Due to the change in the width of the punching rod 10, the distance between it and the inner wall of the laboratory vessel changes. The distance at the bottom is small, resulting in a small wind pressure. Blowing downward makes the punching rod 10 have a more uniform drying effect on the laboratory vessel.

[0094] Specifically, the principle of the present invention is: when using, before using the drip rack, ensure that the laboratory utensils have been cleaned and are in a semi-dry state. There should not be too much water on the surface of the utensils to dry more efficiently. Install the drip rack in an appropriate place, usually near the sink. As needed, the back plate is installed on the PP rack cavity through a movable connection. The drip rack can be hung above the sink with a hook to ensure that the drip rack is stable and not easy to tilt. Ensure that the PP rack cavity is at a reasonable angle so that the sink of the drip rack can effectively guide water into the drainage pipe to avoid water accumulation affecting the drying effect. Ensure that the breeze heating component is properly connected to the power supply. Most of these devices need to be connected to a standard power socket to ensure that the device can work properly. Adjust the wind speed and heating temperature of the breeze heating component. Most drip racks have a temperature control function, usually keeping the temperature below 50°C to ensure that the high temperature causes accelerated aging damage to the PP punch rod itself. Hang the cleaned laboratory utensils on the drip rack. Directly contact the bottom or side of the utensils with the airflow emitted by the punch rod. Make sure the vessel remains stable on the perforated rod to avoid unnecessary tilting due to excessive weight or uneven hanging. Turn on the breeze heating assembly, and warm air will blow out from the perforated rod and pass through the inner and outer surfaces of the vessel. Make sure that every area on the vessel is evenly exposed to the airflow. Observe the drying process and adjust the intensity of the warm air as needed until the vessel is completely dry. Depending on the specifications and shape of the laboratory vessels, the operator can set different drying times and wind speeds during multiple drying processes, and automatically cut off the power after a certain period of time; ensure that they are dry and have no residual moisture. Remove the dried vessels and ensure that they are completely dry and have no residual moisture.

[0095] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
