Description

Technical Field

[0001] The utility model belongs to the technical field of coal tar density detection, in particular to a coal tar density detection auxiliary device. Background Art

[0002] Coal tar is a black or dark brown, viscous liquid with a pungent odor produced during the dry distillation of coal. It is generally used as a raw material for processing and refining to produce various chemical products. Before manufacturing, the density of coal tar must be tested.

[0003] Testing the density of coal tar helps understand its physical properties, determine whether its quality meets standards, and evaluate its performance in subsequent processing or applications. Coal tar and asphalt samples are viscous, dark, opaque, and highly adhesive, making density determination at room temperature impossible using conventional glass floats. Density measurements typically require heating the sample to a constant temperature to achieve optimal fluidity. The most basic instruments are a graduated cylinder and a glass float.

[0004] However, in the prior art, the auxiliary device for detecting the coal tar density of coal tar has a complex structure and may cause inaccurate detection results due to temperature differences. Utility Model Content

[0005] To address the shortcomings of related technologies, the present invention provides a coal tar density testing auxiliary device. The sample testing chamber, containing the sample, is immersed in a water bath, ensuring that the sample is fully heated and maintained at a constant temperature. The detergent barrel and the thermometer and densitometer it contains are kept at the same temperature as the sample testing chamber. Inserting the densitometer into the sample testing chamber minimizes any significant temperature changes in the sample, thus maintaining test accuracy. Furthermore, the detergent barrel replaces the lid of the hot bath, eliminating the need for a separate opening and lid. This addresses the existing technical issue of inaccurate test results due to temperature differences.

[0006] The utility model provides a coal tar density detection auxiliary device, comprising:

[0007] A hot bath box, wherein a liquid injection hole is opened on the top of the hot bath box;

[0008] a detergent barrel, the detergent barrel being used to be plugged into and sealed in the liquid injection hole;

[0009] a sample detection chamber, the sample detection chamber being located in the heat bath, and the top of the sample detection chamber being connected to the upper surface of the heat bath;

[0010] A sample discharge channel, the top of which is connected to and communicated with the top of the sample detection chamber, and the bottom of which is communicated with the outside world;

[0011] A first valve is provided in the sample discharge channel, and the first valve is used to open or close the corresponding sample discharge channel.

[0012] In this technical solution, the sample testing chamber containing the sample is immersed in a water bath, ensuring that the sample is fully heated and maintained at a constant temperature. The detergent bucket and the thermometer and densitometer it contains are kept at the same temperature as the sample testing chamber. Inserting the densitometer into the sample testing chamber does not significantly change the sample temperature, thus maintaining accuracy. Furthermore, the detergent bucket replaces the lid of the hot bath, eliminating the need for a separate opening and lid.

[0013] In some embodiments, the hot bath includes an outer box and an inner tank; a heating element is provided in the inner tank.

[0014] In the technical solution, this design makes the equipment safer and more durable. The outer box can provide protection from external damage to the inner tank, while the inner tank can directly heat the sample testing chamber to heat the coal tar, ensuring heating efficiency and safety.

[0015] In some embodiments, a temperature control component is provided inside the inner liner of the outer box body, and the temperature control component is electrically connected to the heating element. The temperature control component is used to adjust the heating value of the heating element.

[0016] In the technical solution, the temperature control component can accurately adjust the heating value of the heating element, thereby achieving precise control of the heating temperature of the coal tar, which not only ensures the heating effect but also prevents safety problems that may be caused by overheating.

[0017] In some embodiments, the opening of the detergent barrel is located at the top thereof, and the opening of the detergent barrel is provided with an end cover.

[0018] In the technical solution, it is convenient to add detergent, and the end cover can keep the detergent clean and prevent volatilization and pollution.

[0019] In some embodiments, a drain pipe is provided at the bottom of the outer side wall of the outer box body, the drain pipe is connected to and communicated with the bottom of the inner container, and a second valve is provided on the drain pipe.

[0020] In the technical solution, the drain pipe is connected to the bottom of the inner tank to conveniently drain the water or oil used for heating. The second valve can control the opening and closing of the drain pipe to prevent liquid leakage.

[0021] In some embodiments, a flange is extended upward from an edge of the upper surface of the outer box.

[0022] In the technical solution, the flange design prevents spilled samples from flowing into the sample testing chamber or hot bath, thus avoiding equipment damage or measurement errors.

[0023] In some embodiments, inside the outer box, a sample arrangement area is formed below the inner tank, and the bottom of the sample arrangement channel is located in the sample arrangement area; the side wall of the outer box is provided with an avoidance opening connected to the sample arrangement area.

[0024] In the technical solution, tested samples can be placed in a trash can through the bypass port. After opening the first valve, the sample discharge channel directly discharges the samples in the corresponding sample testing chamber into the trash can. The trash can can be removed through the bypass port, making manual operation convenient.

[0025] In some embodiments, a vertical side wall of the outer box body is provided with a clearance groove for the first valve to pass through, and the first valve passes through the corresponding clearance groove.

[0026] In the technical solution, the first valve can be operated manually from the outside without having to put one's hands into a narrow space for operation, thus facilitating manual operation.

[0027] In some embodiments, the sample detection chambers are arranged in multiple numbers at intervals.

[0028] In the technical solution, the design of multiple sample detection chambers can simultaneously detect multiple coal tar samples, improving detection efficiency. At the same time, the interval setting can also prevent mutual interference between samples, ensuring the accuracy of detection.

[0029] In some embodiments, the heat bath is provided with an electric stirrer to ensure uniform heating of the medium.

[0030] Based on the above technical solution, in an embodiment of the present invention, the sample testing chamber containing the sample is immersed in a water bath, ensuring that the sample is fully heated and maintained at a constant temperature. The detergent bucket and the thermometer and densitometer it contains are exposed to the same temperature as the sample testing chamber. Inserting the densitometer into the sample testing chamber does not significantly change the sample temperature, thus not affecting test accuracy. Furthermore, the detergent bucket replaces the lid of the hot bath, eliminating the need for a separate opening and lid for the hot bath. BRIEF DESCRIPTION OF THE DRAWINGS
