[0004] Although the above patent can extract the propionyl chloride liquid, the above-mentioned chloropropionyl chloride material extraction device still has the following problems: when extracting the propionyl chloride liquid, it is necessary to insert the insertion pipe into the inside of the filling barrel. Then, when pulling out the insertion pipe, the surface of the insertion pipe will be attached with propionyl chloride liquid, and the propionyl chloride liquid cannot be scraped off, resulting in accidental contact by the staff.

[0005] In view of the above problems, for this reason, a material extraction device with high safety is proposed. Content of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a high-safety material extraction device, including a moving base 1, a motor 2 is fixedly installed on the top of the moving base 1, a threaded rod 3 is fixedly installed on the output end of the motor 2, two support plates 7 are fixedly installed on the top of the moving base 1, slideways 8 are opened on both of the two support plates 7, a material extraction box 5 is slidably connected inside the two slideways 8, a moving block 4 is fixedly installed on the surface of the material extraction box 5, the moving block 4 is threadedly connected to the surface of the threaded rod 3, a push rod motor 6 is fixedly installed on the top of the material extraction box 5, the output end of the push rod motor 6 slidably penetrates through the material extraction box 5 and extends into the material extraction box 5, and a piston is fixedly installed on the output end of the push rod motor 6, and the piston is slidably connected inside the material extraction box 5.

[0026] Start the motor 2 to drive the threaded rod 3 to rotate, so that the moving block 4 moves upward, so that the material extraction box 5 moves upward, so that the material extraction box 5 slides inside the two slideways 8, which is convenient for adjusting the height of the material extraction box 5.

[0027] One side of the material extraction box 5 is fixedly installed with an insertion pipe 9. A connection box 13 is fixedly sleeved on the surface of the insertion pipe 9. The connection box 13 is internally communicated with the insertion pipe 9. Two fixing rods 16 are fixedly installed inside the connection box 13. Two moving plates 18 are slidably connected to the two fixing rods 16. A sealing plug 19 is fixedly installed on the two moving plates 18. The sealing plug 19 is located at the connection between the connection box 13 and the insertion pipe 9. Two elastic springs 17 are movably sleeved on the two fixing rods 16. The lower ends of the two elastic springs 17 are respectively fixedly connected to the two moving plates 18, and the upper ends of the two elastic springs 17 are respectively fixedly connected to the two fixing rods 16.

[0028] By adjusting the height of the material extraction box 5, the insertion pipe 9 is inserted into the propionyl chloride filling barrel. Then, the push rod motor 6 is started, and the push rod motor 6 drives the piston to move upward, so that the propionyl chloride is sucked into the interior of the material extraction box 5 through the insertion pipe 9, which is convenient for extracting the propionyl chloride.

[0029] During the suction process, the sealing plug 19 will move upward, so that the two moving plates 18 slide on the two fixing rods 16, squeezing the two elastic springs 17, so that the propionyl chloride enters the interior of the connection box 13 and then enters the interior of the material extraction box 5. When no longer sucking the propionyl chloride, the two moving plates 18 and the sealing plug 19 are reset by the elastic force of the two elastic springs 17, so that the sealing plug 19 seals the connection between the insertion pipe 9 and the connection box 13, realizing the sealing of the connection box 13, preventing external impurities from entering the interior of the material extraction box 5, and at the same time preventing the propionyl chloride inside the material extraction box 5 from flowing back.

[0030] A fixing plate 10 is fixedly sleeved on the insertion pipe 9. Two sliding rods 11 are slidably connected inside the fixing plate 10. A blocking ring 14 is fixedly installed at the lower ends of the two sliding rods 11. Two springs 12 are movably sleeved on the two sliding rods 11. The upper ends of the two springs 12 are respectively fixedly connected to the bottom of the fixing plate 10, and the lower ends of the two springs 12 are fixedly connected to the blocking ring 14. A scraping ring 15 is fixedly installed inside the blocking ring 14.

[0031] When the insertion pipe 9 moves downward, the blocking ring 14 will be blocked by the mouth of the propionyl chloride filling barrel, so that the blocking ring 14 no longer moves downward. As the insertion pipe 9 continues to move downward, the two sliding rods 11 will slide inside the fixing plate 10, squeezing the two springs 12, so that the scraping ring 15 contacts the surface of the insertion pipe 9. When the insertion pipe 9 moves upward, the propionyl chloride on the surface of the insertion pipe 9 is scraped by the scraping ring 15, which is convenient for cleaning the surface of the insertion pipe 9 and preventing residues.

[0032] Working principle:

[0033] Start the motor 2 to drive the threaded rod 3 to rotate, thereby causing the moving block 4 to move upward, thereby causing the material extraction box 5 to move upward, thereby causing the material extraction box 5 to slide inside the two slideways 8, thereby facilitating the height adjustment of the material extraction box 5. When sucking materials, the sealing plug 19 will move upward, thereby causing the two moving plates 18 to slide on the two fixed rods 16, thereby squeezing the two elastic springs 17, so that propionyl chloride enters the inside of the connection box 13 and then enters the inside of the material extraction box 5. When no longer sucking propionyl chloride, the two moving plates 18 and the sealing plug 19 are reset by the elastic force of the two elastic springs 17, so that the sealing plug 19 seals the connection between the extension pipe 9 and the connection box 13.

[0034] When the extension pipe 9 moves downward, the blocking ring 14 will be blocked by the mouth of the propionyl chloride filling barrel, so that the blocking ring 14 no longer moves downward. Then, as the extension pipe 9 continues to move downward, the two sliding rods 11 will slide inside the fixing plate 10, thereby squeezing the two springs 12, so that the scraping ring 15 contacts the surface of the extension pipe 9. When the extension pipe 9 moves upward, the propionyl chloride on the surface of the extension pipe 9 is scraped off by the scraping ring 15.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
