Description

Technical Field

[0001] This invention relates to the field of drying technology for explosive evidence, and in particular to a dryer for extracting key physical evidence from gas explosion sites. Background Technology

[0002] When a gas explosion occurs in a certain place, in order to quickly find the cause of the explosion, it is necessary to dig out and extract key physical evidence information at the scene of the gas explosion. However, there may be impurities in the collected physical evidence or dust adhering to the physical evidence. In this case, it is necessary to clean the physical evidence and dry it quickly.

[0003] The existing patent publication number "CN208983771U" discloses a metal dryer, which has an air inlet pipe, an electric heating pipe and a hot air outlet pipe installed inside the drum. The air inlet pipe, the electric heating pipe and the hot air outlet pipe are all fixedly installed in the bearing seat. During the operation, the oil cylinder always lifts the heat preservation cover. Since the heat preservation cover and the drum are mounted on the drum support, the drum also has an inclined slope. The metal material to be dried is discharged from the discharge port as the drum rolls.

[0004] The above description has the following problems: this metal dryer is large in size, occupies a lot of space, is inconvenient to use, and has a high operating power, making it unable to dry materials quickly. Therefore, in order to solve the existing technical problems, the applicant, together with other units, undertook a National Key Research and Development Program project (Project Name: Research on Key Physical Evidence Information Mining Technology and Extraction Equipment at Gas Explosion Scenes, Project No.: 2023YFC3304103). This application is part of the research results of this key research and development program project. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0042] refer to Figure 1 This utility model provides a drying machine for extracting key physical evidence at gas explosion sites, which is used to quickly dry key physical evidence (such as metal materials) extracted at gas explosion sites after cleaning.

[0043] refer to Figure 1 , Figure 2 and Figure 3Specifically, it includes a material bucket 1, a drive unit 2, a main body 3, a heating tube 4, a control component 6, and a start / stop button 7.

[0044] refer to Figures 2-4 The material bin 1 includes an outer bin 11 and an inner bin 12 disposed inside the outer bin 11. The inner bin 12 is used to hold key evidence after cleaning. Several mesh holes 13 are provided on the wall of the inner bin 12. The bottom of the outer bin 11 is provided with a discharge pipe 14 communicating with its interior. The outlet end of the discharge pipe 14 extends to the outside of the dryer. This material bin 1 can be made of a metal material with good thermal conductivity, and the walls of the outer bin 11 and the inner bin 12 are relatively thin, which can improve the heat conduction speed.

[0045] refer to Figures 2-4 The drive component 2 is used to drive the inner drum 12 to rotate; the drive component 2 is a drive motor. The main body 3 includes a base 31 and a protective shell 32 for accommodating the material drum 1, which is set on the base 31. The main body of the drive component 2 is set on the base 31. The drive shaft of the drive motor extends into the inner drum 11 and is connected to the outer bottom wall of the inner drum. Sealed bearings are provided at the positions where the drive motor passes through the protective shell 32 and the outer drum 11. The sealed bearings ensure that the drive shaft of the drive motor is rotatably connected to the protective shell 32 and the outer drum 11, and at the same time ensure the sealing effect to prevent water leakage from the outer drum 11.

[0046] refer to Figures 2-4 Multiple heating tubes 4 are provided, and these heating tubes 4 are arranged inside the protective shell 32 and evenly distributed along the circumference of the outer barrel 11. The heating tubes 4 are U-shaped heating tubes, which are inverted inside the protective shell 32. The heating tubes 4 can be of the Ruigao brand, model RGUX; the voltage is 12V-440V. By using U-shaped heating tubes 4, the heating efficiency can be improved, and the heat distribution is more uniform, thereby improving the drying efficiency and quality of key materials in the material barrel 1.

[0047] refer to Figures 2-4 The inner wall of the protective shell 32 is provided with a heat insulation layer 5. The heat insulation layer 5 has a good heat insulation effect, which can reduce the temperature of the exposed surface of the protective shell and protect the on-site operators from burns.

[0048] refer to Figure 1 , Figure 2 and Figure 5 The control component 6 is located inside the base 31, and the drive motor and heating tube 4 are both connected to the control component 6 by wires. The start / stop button 7 is located on the base 31 and is connected to the control component 6 by wires. When the start / stop button 7 is pressed, the operation of the heating tube 4 and the drive component 2 is controlled by the control component.

[0049] refer to Figure 2 , Figure 3 and Figure 4 Working principle: After cleaning, the key evidence is placed in the inner barrel 12. Since moisture may remain on the cleaned evidence, it can be initially drained through the inner barrel 12 with mesh 13. The drained water is collected in the outer barrel 11 and discharged from the dryer through the discharge pipe 14. When the start / stop button 7 is pressed to start the dryer, the drive motor drives the inner barrel 12 to rotate. Under the action of centrifugal force, the residual moisture on the metal evidence can be thrown out. At the same time, the heating tube 4 heats the material barrel 1, which can achieve uniform heating of the key evidence and improve drying efficiency. If there are still some fine impurity particles remaining on the metal evidence, they can be thrown off the metal during the rotation drying process and enter the outer barrel 11 through the mesh 13. The thrown-out particles can be discharged from the outer barrel 11 with the drained water.

[0050] refer to Figure 1 The upper surface of the base 31 is inclined, and the bottom of the protective shell 32 is located on the inclined surface of the base 31. By setting the protective shell 32 on the inclined surface of the base 31, the material bucket 1 installed inside the protective shell 32 is also inclined, which facilitates the placement and removal of metal evidence.

[0051] refer to Figure 1 The outer surface of the base 31 is also equipped with a heating timer button 8 and a temperature control knob 9, both of which are wired to the control component 6. The heating timer button 8 and temperature control knob 9 control the heating time and temperature of the heating element, making this drying device more intelligent. A heating indicator light 10 is also provided on the outer surface of the base 31, allowing operators to easily check whether the drying device is in heating mode.

[0052] In summary, the material bin 1, drive unit 2, heating element 4, control component 6, and start / stop button 7 of this dryer are integrated into the main body 3. This dryer is small and lightweight, reducing its footprint and space requirements. It is easy to operate, highly portable, and better enhances the user's quality experience. Moreover, by using the material bin 1 to initially drain the key materials after cleaning, and by using centrifugal force to remove residual water during operation, while heating through the heating element 4, the key materials in the material bin 1 are heated evenly, greatly improving drying efficiency and shortening drying time.
