Description

Technical Field

[0001] This utility model belongs to the technical field of drying devices, specifically relating to a portable sample storage device. Background Technology

[0002] During service, workpieces often fracture due to harsh operating environments. The fracture surface is usually contaminated or contains moisture, which can affect subsequent fracture analysis. For example, the fracture surface of oil and gas pipelines exposed to humid environments for extended periods will develop severe corrosion, impacting data results when analyzing fracture mechanisms. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a portable sample storage device, which is especially suitable for portable and dry storage of metal samples. It has the advantages of simple operation, short time consumption and high test efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable sample storage device, including a rotating handle welded to the top of the box, an observation window installed on the side of the box, an insulation layer installed inside the box, a one-way valve installed on the top of the box, a threaded post welded to the chassis, the inner wall of the box connected to the chassis through the threaded post, a base installed at the bottom of the chassis, a trapezoidal hole provided on the side of the base, a motor installed on the top of the chassis, blades installed on the rotating shaft of the motor, a partition plate installed above the blades, a round hole provided on the partition plate, a large perforated column plate welded to the top of the partition plate, a heating wire provided on the outer side of the large perforated column plate, a small perforated column plate welded to the top of the partition plate, a support rod installed at the center of the top of the partition plate, a cover plate installed on the top of the support rod, the top of the support rod connected to a cross joint, and the top of the cross joint connected to the box through the insulation layer and the one-way valve.

[0005] Both the chassis and the base are provided with fan-shaped holes, and the upper part of the base is provided with a fan-shaped boss. The chassis and the base are connected by a rotating pair. The chassis is installed on the upper part of the base. Before and after drying, the base is rotated so that the fan-shaped holes and the fan-shaped boss of the base can be used to make the inside of the box either sealed or open.

[0006] The lower end of the support rod is welded to the top of the partition, and the upper end of the support rod is connected to the top of the box inside through a cross joint.

[0007] The threaded column is welded to the chassis, and the lower part of the inner wall of the box is threaded. During drying, the inner wall of the box is connected to the chassis through the thread.

[0008] The electric motor is installed below the blades. During drying, the electric motor provides power to the blades, which generate an upward airflow. Under the action of the heating wire, the temperature inside the chamber rises, thus drying the sample.

[0009] The cross-shaped connector has a cross-shaped structure with a threaded top and through holes on the other three ends.

[0010] The aforementioned shield has ventilation holes.

[0011] The beneficial effects of this utility model are:

[0012] The side of the box of this utility model is equipped with an observation window, which can be used to observe the drying process of the sample so as to evaluate the drying effect of the sample.

[0013] The box of this invention has an internal insulation layer, which can be used to keep the temperature inside the box constant during the drying process of the desiccant.

[0014] The top of the chamber of this utility model is equipped with a one-way valve, which is used for one-way discharge of gas during and after the drying process to prevent gas backflow from affecting the drying effect.

[0015] The upper part of the partition of this utility model is welded with a large perforated column plate, and a heating wire is provided on the outer side of the large perforated column plate, which can avoid the sample from directly contacting the heating wire and damaging the sample.

[0016] This invention can be used to dry samples. Since the base of this invention has a fan-shaped hole and the upper part of the base has a fan-shaped protrusion, the base can be rotated after drying to make the fan-shaped hole of the base match the fan-shaped protrusion of the base, so that the inside of the chamber is sealed. After the temperature inside the chamber naturally drops to room temperature, the drying of the sample is completed. It has the advantages of simple operation, short time consumption and high test efficiency. Attached Figure Description

Detailed Implementation

[0026] The structural principle and working principle of this utility model device will be further described in detail below with reference to the accompanying drawings.

[0027] See Figure 1-7 This allows for the drying of the sample.

[0028] The enclosure includes a rotating handle 1, which is welded to the top of the housing 2. An observation window 3 is installed on the side of the housing 2. An insulation layer 12 is installed inside the housing 2. A one-way valve 10 is installed on the top of the housing 2. A threaded post 16 is welded to the chassis 4. The inner wall of the housing 2 is connected to the chassis 4 through the threaded post 16. A base 5 is installed at the bottom of the chassis 4. A trapezoidal hole is provided on the side of the base 5. An electric motor 6 is installed on the top of the chassis 4. A blade 7 is installed on the rotating shaft of the electric motor 6. A partition 8 is installed above the blade 7. The partition 8 has a round hole. A large perforated column plate 14 is welded to the top of the partition 8. A heating wire 13 is provided on the outside of the large perforated column plate 14. A small perforated column plate 17 is welded to the top of the partition 8. A support rod 15 is installed at the center of the top of the partition 8. A cover plate 9 is installed on the top of the support rod 15. The top of the support rod 15 is connected to a cross joint 11. The top of the cross joint 11 is connected to the one-way valve 10 through the insulation layer 12 and the housing 2.

[0029] Both the chassis 4 and the base 5 are provided with fan-shaped holes, and the upper part of the base 5 is provided with a fan-shaped boss. The chassis 4 and the base 5 are connected by a rotating pair. The chassis 4 is installed on the upper part of the base 5. Before and after drying, the base 5 is rotated so that the fan-shaped holes and the fan-shaped boss of the base 5 are used to make the inside of the box 2 either sealed or open.

[0030] The lower end of the support rod 15 is welded to the top of the partition plate 8, and the upper end of the support rod 15 is connected to the cross joint 11 and fixed to the top of the inside of the box 2.

[0031] The threaded post 16 is welded to the chassis 4, and the lower part of the side wall of the box 2 is provided with threads. When drying, the side wall of the box 2 is connected to the chassis 4 through the threads.

[0032] The motor 6 is installed below the blade 7. During drying, the motor 6 provides power to the blade 7, which generates an upward airflow. Under the action of the heating wire 13, the temperature inside the chamber 2 rises, thus drying the sample.

[0033] The cross-shaped connector 11 has a cross-shaped structure with a threaded top and through holes on the other three ends.

[0034] The shield 9 has ventilation holes 18.

[0035] The working principle of this utility model is as follows:

[0036] First, place the sample inside the cylindrical space formed by the partition 8, the large perforated column plate 14, and the small perforated column plate 17. Place the shield 9 through the center hole above the support rod 15 on the upper surface of the large perforated column plate 14. Then, place the box 2 above the base 4, ensuring the cross joint 11 on the upper wall of the box 2 is on the same axis as the support rod 15. While fixing the base 4, rotate the handle 1 to tightly engage the threads on the inner wall of the box 2 with the threaded post 16 on the base 4, allowing the upper end of the support rod 15 to pass through the lower end of the cross joint 11. The fan-shaped holes on the base 4 and the base 5 are closed when not overlapping. Rotate the base 5 to align the fan-shaped holes on the base 5 and the base 4 vertically. At this point, the inside of the box 2 is open. Finally... Turn on the power to the heating wire 13 and the motor 6. The motor 6 provides power to the blades 7, which generate an upward airflow. Under the action of the heating wire 13, the internal temperature of the chamber 2 rises, drying the sample. Check the drying status of the sample inside the chamber through the observation window 3 on the chamber 2. When the sample is dry enough to meet the requirements for use in the laboratory, fix the base 4 and rotate the base 5 so that the fan-shaped protrusion of the base 5 and the fan-shaped hole of the base 4 are in the same position in the vertical direction, keeping the inside of the chamber 2 in a closed state to keep the dried sample warm and dry. Turn off the power to the heating wire 13 and the motor 6. After the internal temperature of the chamber 2 cools down to room temperature naturally, rotate the handle 1 to separate the chamber 2 from the base 4. Remove the cover plate 9 and take out the sample, which is then ready for testing.
