Description

Technical Field

[0001] This utility model belongs to the field of laboratory equipment, and specifically relates to a glass condenser. Background Technology

[0002] Glass condensers are commonly used equipment in laboratories. Their transparency, corrosion resistance, ease of cleaning, and maintenance contribute to their widespread use. The working principle of a laboratory glass condenser primarily involves using cooling water to cool the fluid inside the tubes. The cooling water enters from the bottom of the condenser and exchanges heat with the fluid through the outer wall of the glass tubes, carrying away the heat from the fluid and thus achieving condensation. In addition, glass condensers are also used in experiments for collecting gases, purifying and concentrating liquids.

[0003] Currently, commonly used glass condensers in laboratories are typically either spiked or internal coil type. However, spiked glass condensers have a relatively complex design, requiring high-precision machining equipment and processes, resulting in higher manufacturing costs. Internal coil type glass condensers, due to their complex internal structure (such as the coil design), make cleaning relatively difficult, requiring frequent cleaning and maintenance to maintain normal functionality. Furthermore, liquids adhering to the interior of traditional spiked or internal coil type glass condensers can only be cleaned by prolonged boiling with acid or alkali solutions, which is insufficient and significantly affects product quality. Additionally, both types of glass condensers have the disadvantage of a relatively small heat exchange area. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a novel glass condenser for laboratory use. By filling the condenser with several hollow glass column-shaped packing materials, the heat exchange area of ​​the glass condenser can be significantly increased, thereby effectively improving the condensation efficiency. Furthermore, the glass condenser can be connected to other instruments or components through connecting sleeves, connecting bolts, and nuts, which facilitates the installation, connection, and disassembly of the glass condenser with other instruments. At the same time, it is easy to remove the condenser packing materials inside the glass condenser, making it convenient to clean the inner wall of the glass condenser and the condenser packing materials.

[0005] The present invention discloses a glass condenser, wherein the glass condenser is filled with a plurality of condenser packings, the condenser packings being hollow glass columns, the condenser packings filling the glass condenser, a condenser jacket attached to the outer wall of the glass condenser, a water inlet at the upper end of the condenser jacket, a water outlet at the lower end of the condenser jacket, and polytetrafluoroethylene screen plates at both the upper and lower ends of the glass condenser.

[0006] Furthermore, the condenser packing includes ceramic columns and ceramic rings.

[0007] Furthermore, the hollow glass column has an outer diameter of 5-6 mm, an inner diameter of 3-4 mm, a wall thickness of 1 mm, and a column height of 3-5 mm. The column wall of the hollow glass column is provided with a plurality of evenly spaced first circular holes, the diameter of which is 1-2 mm.

[0008] Furthermore, the polytetrafluoroethylene sieve plate is provided with a plurality of second circular holes arranged at intervals.

[0009] Furthermore, the diameter of the second circular hole is 3-5 mm.

[0010] Furthermore, it also includes a connecting sleeve, connecting bolts, and nuts. The lower end of the glass condenser is fitted with the connecting sleeve, and the connecting sleeve is fixedly installed by the connecting bolts and nuts.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, a glass condenser 1 is filled with a plurality of condenser packings 4, which are hollow glass columns. The condenser packings 4 are filled inside the glass condenser 1. A condenser jacket 3 is attached to the outer wall of the glass condenser 1. The upper end of the condenser jacket 3 is provided with a water inlet 5, and the lower end of the condenser jacket 3 is provided with a water outlet 6. Both the upper and lower ends of the glass condenser 1 are provided with polytetrafluoroethylene screen plates 2.

[0022] In this embodiment, the glass condenser 1 can be used in the laboratory, specifically as a distillation condenser or a distillation column, and also as a reactor for gas-liquid, gas-gas, or liquid-liquid contact. The inlet 5 and outlet water can be used to supply or discharge cooling water to the inside of the glass condenser 1 for cooling, or to introduce heat transfer oil or hot water below 100°C to heat the inside of the glass condenser 1. Polytetrafluoroethylene (PTFE) sieve plates 2 are located at the upper and lower ends of the glass condenser 1 for connection with other components; they can serve as support plates for the packing material or as pads for connection with other components.

[0023] Specifically, by filling the condenser with several hollow glass column-shaped condenser packings 4, the heat exchange area of ​​the glass condenser 1 can be significantly increased, thereby effectively improving the condensation efficiency.

[0024] The condenser packing 4 can be installed by drilling, gluing, or using a separate clamp. The specific installation methods are existing conventional technologies and will not be described in detail here. The condenser jacket 3 is clamped to the outer wall of the glass condenser 1 by its own clamping action, thereby achieving a fixed connection with the glass condenser 1.

[0025] In one alternative embodiment, the condenser packing 4 includes ceramic columns and ceramic rings.

[0026] Specifically, using hollow glass columns, ceramic columns, and ceramic rings as condenser packing 4 can fully utilize their advantages of high temperature resistance and corrosion resistance, which is conducive to improving the service life of condenser packing 4 and ensuring the stable and reliable conduct of experiments.

[0027] In one alternative implementation, such as Figure 3 As shown, the hollow glass column has an outer diameter of 5-6 mm, an inner diameter of 3-4 mm, a wall thickness of 1 mm, and a column height of 3-5 mm. The column wall 41 of the hollow glass column is provided with a plurality of uniformly spaced first circular holes 42, the diameter of which is 1-2 mm.

[0028] By providing multiple evenly spaced first circular holes 42 on the column wall 41 of the hollow glass column, it is beneficial to increase the air permeability and heat exchange area of ​​the hollow glass column, which serves as the condenser packing 4, thereby further improving the condensation efficiency.

[0029] Specifically, taking a hollow glass column with an outer diameter of 5mm, an inner diameter of 3mm, and a column height of 4mm as an example, the calculation is performed using the formula S1=2π(r 内 +r 外 )H+2π(r 内 -r 外 ) 2 Calculate its surface area:

[0030] We can obtain S1 = 2π(2.5mm + 1.5mm) × 4mm + 2 × π(2.5mm - 1.5mm) 2 =34πmm 2 Its volume is V1=πr 2 H = (2.5mm) 2 ×4mm×π=25πmm 3 .

[0031] Taking a hollow glass condenser 1 with an inner diameter of 60mm and a height of 1000mm as an example, its inner wall area is calculated as S² = 2πrH = 2π × 30 × 1000 = 60000π mm². 2 Its internal volume is V2=πr 2 H=π30 2 ×1000mm 3 .

[0032] The number of hollow glass columns that can be filled in the hollow glass condenser 1 is n1 = V2 / V1 = 36000; the total area of ​​all hollow glass columns is S3 = n1 × S1 = 1224000π mm. 2 ,

[0033] The ratio of the total area of ​​all hollow glass columns to the inner wall area of ​​the hollow glass condenser 1, i.e., the multiple of the heat exchange area, is n2=S3 / S2=20.4.

[0034] It is easy to conclude that the smaller the outer diameter and inner diameter of the condenser packing 4, and the smaller its height, the larger its specific surface area, and the more condenser packing 4 is filled in the hollow glass condenser 1; the larger the inner diameter of the glass condenser 1, the more condenser packing 4 is filled in it, and the greater the multiple of the increased heat exchange area.

[0035] Therefore, in this embodiment, by arranging the hollow glass columns as closely as possible, the more condenser packing 4 there are in the glass condenser 1, the greater the increase in heat exchange area, and the greater the corresponding increase in condensation efficiency.

[0036] In one alternative implementation, such as Figure 2 As shown, multiple second circular holes 9 are arranged at intervals on the polytetrafluoroethylene sieve plate 2.

[0037] The diameter of the second circular hole 9 is preferably 3-5 mm.

[0038] Specifically, by arranging multiple second circular holes 9 at intervals on the PTFE sieve plate 2, it is possible for gas or liquid to enter or exit the interior of the glass condenser 1 through the PTFE sieve plate 2.

[0039] In one optional embodiment, it also includes a connecting sleeve 7, a connecting bolt and a nut 8. The lower end of the glass condenser 1 is fitted with the connecting sleeve 7, and the connecting sleeve 7 is fixedly installed by the connecting bolt and the nut 8.

[0040] Specifically, when there is liquid adhering to the packing inside the condenser, the connecting sleeve 7, connecting bolts and nuts 8, and PTFE screen plate 2 can be removed to remove the condenser packing 4 inside the glass condenser 1. After cleaning and drying the inner wall of the glass condenser 1 and the condenser packing 4 with solvent, they can be reassembled and reused.

[0041] Therefore, this utility model enables the glass condenser 1 to be connected to other instruments or components through the connecting sleeve 7, connecting bolts and nuts 8, thereby facilitating the installation, connection and disassembly of the glass condenser 1 with other instruments. At the same time, it facilitates the removal of the condenser packing 4 inside the glass condenser 1, making it easier to clean the inner wall of the glass condenser 1 and the condenser packing 4.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
