[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a crude benzene extraction tank, including an extraction tank body 1, a tank cover 2, a heating chamber 3, a heater 4, a base 5, a handle 6, a feed inlet 7, a one-way valve 8, a guide pipe 9, a connecting pipe 10, a connecting bolt 11, a limiting block 12, a first support frame 13, a connecting seat 14, a second support frame 15, a first connecting block 16, a connecting bolt 17, a second connecting block 18, a support plate 19, a discharge pipe 20, a sealing joint 21, a cooling pipe 22, a cooling chamber 23, a locking bolt 24, a locking block 25, and an exhaust hole 26.

[0029] Specific examples Figure 1 , Figure 2 and Figure 3 As shown, firstly, a connecting seat 14 is connected to the lower side of the can lid 2. The longitudinal section of the connecting seat 14 is trapezoidal. A first support frame 13 is installed on the lower side of the connecting seat 14. The heating chamber 3 is placed horizontally. Limiting blocks 12 are connected to both the left and right sides of the heating chamber 3. The limiting blocks 12 are symmetrically arranged about the center line of the heating chamber 3. The limiting blocks 12 have an "H" shape. The lower side of the limiting block 12 is aligned with the opening of the second support frame 15. The second support frame 15 is pushed, so that friction is generated between the inner side of the second support frame 15 and the outer bottom of the limiting block 12. The limiting block 12 and the second support frame 15 are slidably connected until the limiting block 12 and the second support frame 15 are completely engaged.

[0030] Next, the second support frame 15 is lifted so that the upper side of the limiting block 12 is aligned with the opening of the first support frame 13. The first support frame 13 and the second support frame 15 are oriented in opposite directions. The second support frame 15 is pushed, and friction is generated between the inner side of the first support frame 13 and the upper outer side of the limiting block 12. The limiting block 12 and the first support frame 13 slide together until the limiting block 12 and the first support frame 13 are fully engaged. At this time, the bottom end of the first support frame 13 contacts the upper side of the second support frame 15. The first connecting block 16 is symmetrically arranged about the center line of the first support frame 13. The outer side of the second support frame 15 is provided with a second connecting block 18 symmetrically arranged about the front and back. When the support frame 15 contacts the first support frame 13, the second connecting block 18 contacts the first connecting block 16. A connecting bolt 17 is screwed into the inside of the second connecting block 18 and the first connecting block 16. The connecting bolt 17 has a threaded structure on the outside and passes through the inside of the first connecting block 16 and the second connecting block 18, so that the first connecting block 16 and the second connecting block 18 are tightly connected by the connecting bolt 17. The limiting block 12 is restricted inside the first support frame 13 and the second support frame 15. The heating chamber 3 is installed horizontally as a whole. The connecting pipe 10 on the upper side of the heating chamber 3 is connected to the guide pipe 9 on the lower side of the tank cover 2 to facilitate the stable support of the crude benzene extraction tank for the internal structure.

[0031] Specific examples Figure 1 and Figure 4 As shown, the cooling chamber 23 is placed inside the extraction tank body 1, so that the drain pipe provided at the left end of the cooling chamber 23 extends outward through the through hole at the bottom left side of the extraction tank body 1, pushing the cooling chamber 23, and friction is generated between the bottom end of the cooling chamber 23 and the bottom inside of the extraction tank body 1. At the same time, the cooling chamber 23 and the extraction tank body 1 are slidably connected until the left side of the cooling chamber 23 contacts the left inside of the extraction tank body 1.

[0032] Next, the cooling pipe 22 is placed vertically, positioned below the sealing joint 21, and is U-shaped. A horizontal convex tube is located on the left side of the cooling pipe 22. Pushing the cooling pipe 22 causes it to vertically engage inside the cooling chamber 23. At this point, the left end opening of the cooling pipe 22 is on the same horizontal line as the vent 26 located in the middle left side of the extraction tank body 1. Two sets of U-shaped locking blocks 25 are selected, engaging on the left and right sides of the cooling pipe 22 respectively. When the inner sides of the two sets of locking blocks 25 are aligned with the cooling pipe 22... When the two sets of locking blocks 25 are engaged and their outer sides are in contact with the inner wall of the cooling chamber 23, the locking bolt 24 is manually tightened. The locking bolt 24 has a threaded structure on its outside. When the locking bolt 24 is tightened, the connection gap between the locking block 25 and the cooling chamber 23 is shortened. The locking bolt 24 is symmetrically arranged about the center line of the locking block 25. The locking bolt 24 passes through the interior of the locking block 25 and is threadedly connected to the locking block 25 and the cooling chamber 23, so that the cooling pipe 22 is limited by the locking block 25 in the cooling chamber 23, which facilitates the limiting and protection function of the crude benzene extraction tank.

[0033] Specific examples Figure 1 and Figure 5 As shown, first place the base 5 connected to the lower side of the extraction tank body 1 on the horizontal operating table. The base 5 has a trapezoidal structure, and the bottom end of the base 5 contacts the top end of the horizontal operating table. The base 5 supports the extraction tank body 1, and at this time the extraction tank body 1 is placed horizontally.

[0034] The handle 6 connected to the upper side of the can lid 2 allows the can lid 2 to be aligned with the upper opening of the extraction tank body 1. Pushing the handle 6 causes the can lid 2 to engage inside the extraction tank body 1. At the same time, the discharge pipe 20 connected to the lower side of the heating chamber 3 engages with the sealing joint 21 connected to the upper end of the cooling pipe 22. The diameter of the sealing joint 21 is larger than the diameter of the discharge pipe 20. The sealing joint 21 wraps around the edge of the discharge pipe 20. The connecting bolt 11 is screwed horizontally into the interior of the connection between the can lid 2 and the extraction tank body 1. The connecting bolt 11 has a threaded structure on the outside. When the connecting bolt 11 is screwed, the connection gap between the extraction tank body 1 and the can lid 2 is shortened. The connecting bolt 11 is threadedly connected to both the can lid 2 and the extraction tank body 1.

[0035] The crude benzene to be extracted is poured into the feed port 7 connected to the upper end of the tank cover 2. After the one-way valve 8 is opened, the crude benzene enters the interior of the heating chamber 3 through the guide pipe 9. The inner side of the heating chamber 3 is provided with a support plate 19, and a heater 4 is installed on the upper side of the support plate 19. When the support plate 19 is opened, the support plate 19 heats the bottom of the heating chamber 3. When the crude benzene passes through the heated area of ​​the heating chamber 3, the flue gas generated by heating will enter the interior of the cooling pipe 22 through the discharge pipe 20. The cooling pipe 22 is placed in the cooling chamber 23 filled with water, so that the flue gas entering the interior of the cooling pipe 22 will be cooled inside the cooling pipe 22.

[0036] The substances that can be condensed will remain inside the cooling pipe 22, while the substances that cannot be condensed will be discharged through the vent 26, which facilitates the cooling and separation function of the crude benzene extraction tank. This is how the crude benzene extraction tank is used.
