Description

Technical Field

[0001] This utility model belongs to the field of chemical extraction technology, and in particular relates to an extraction device for o-chlorobenzyl cyanide after reaction. Background Technology

[0002] o-chlorobenzyl cyanide is an organic compound that is widely used as a raw material in the production of agricultural herbicides and pharmaceutical raw materials. After the reaction, it needs to be extracted from the reaction solution to obtain o-chlorobenzyl cyanide and remove other solutions. The extraction method for o-chlorobenzyl cyanide is called extraction. The extraction of o-chlorobenzyl cyanide is carried out in an extraction tank. The reaction solution and extractant are fed into the extraction tank. After adjusting the extraction temperature, the required o-chlorobenzyl cyanide can be released from the outlet of the extraction tank under the action of centrifugal force.

[0003] A Chinese patent application (or patent) with publication number CN221771584U discloses a chemical extraction and separation device, specifically relating to the field of extraction and separation equipment. This utility model includes a support frame, with an extraction tank fixedly connected to the inner wall of the support frame. A support base is fixedly connected to the bottom of the support frame. One side of the extraction tank has a heavy phase outlet and a light phase inlet, and the other side has a heavy phase inlet and a light phase outlet. By incorporating an anti-adhesion and anti-clogging device, the rotating rod can drive the connecting plate and brush bristles to rotate, thereby cleaning the inner wall of the extraction tank and preventing the extractant from adhering. The rotating plate and the upper curved plate, in conjunction with the brush plate, can clean the bottom of the extraction tank. The curved plate allows the sliding rod to slide on the inner wall at the bottom of the rotating rod, which, in conjunction with the return spring, can reset, thereby driving the hammer block to move up and down, thus clearing blockages at the sealing port.

[0004] The aforementioned chemical extraction and separation equipment is equipped with an anti-movement support device, which includes a support rod. One end of the support rod is connected to the ground via a base, while the other end is connected to a support frame via a U-shaped frame and a connecting block. In actual use, the support rod is first fixed to the support frame, and then the base is pulled to find a suitable position for fixation. However, because the support rod is a rigid object with a non-adjustable length, and the connection between the base and the ground requires drilling and the assembly of impact bolts, it is difficult to find a suitable support position for balance on the ground. Furthermore, although the anti-movement support device is used to position the support frame and the extraction tank within it, thereby preventing displacement caused by the vibration of the extraction tank during operation, the vibration of the extraction tank is not completely eliminated. Part of this vibration is transferred to the connection point between the base and the ground through the support rod and the base, which can easily cause the base to loosen. To address these issues, we provide an extraction device for o-chlorobenzyl cyanide after reaction, which solves the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an extraction device for o-chlorobenzyl cyanide after reaction. By using a damper, the vibration generated during the operation of the extraction tank can be alleviated, and the vibration transmitted from the extraction tank to the base can also be reduced. By using a fixing component that can change the fixed position and its own length, the fixing frame and the extraction tank inside it can be fixed to the base or other positions in the production workshop, thus solving the problems of the above-mentioned chemical extraction and separation equipment.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Meanwhile, the base frame is locked to the base by a fixed component with an interchangeable traction length, thereby improving the stability of the fixed frame. Furthermore, the traction belt in the fixed component can not only be fixed to the base but also to other traction and fixing positions in the production workshop, thus achieving multi-directional positioning of the fixed frame and securing the extraction tank inside the fixed frame.

Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0027] Please see Figure 1-3 This utility model is an extraction device for o-chlorobenzyl cyanide after reaction, including an extraction tank 1, a drive assembly 2 and a damper 6. By using the damper 6, the vibration generated by the extraction tank 1 during operation can be effectively reduced, thereby avoiding the occurrence of severe vibration in the extraction tank 1.

[0028] Specifically, the top of the extraction tank 1 is covered with a tank cover 101, and the drive assembly 2 includes a motor frame 202 mounted on the tank cover 101. The motor frame 202 also houses a drive motor 201, which is connected to the rotating rod 102 via a coupling. A stirring plate 103 is also mounted on the outer wall of the rotating rod 102.

[0029] Furthermore, the rotating rod 102 and the stirring plate 103 are both located inside the extraction tank 1, and the rotating rod 102 is located at the axis of the extraction tank 1. A damper 6 is also installed at the bottom of the extraction tank 1.

[0030] The operation process of this embodiment is as follows: When in use, open the can lid 101 and put the reacted o-chlorobenzyl cyanide solution and extractant into the extraction tank 1. Then close the can lid 101 and start the drive motor 201. The drive motor 201 drives the rotating rod 102 to rotate. The stirring plate 103 on the outer wall of the rotating rod 102 also rotates, so that the reacted o-chlorobenzyl cyanide and extractant in the extraction tank 1 come into full contact, that is, the extraction work is carried out. At the same time, the body of the extraction tank 1 will also vibrate. This vibration is transmitted from the body of the extraction tank 1 to the damper 6 at the bottom and is buffered by the damper 6. Example 2

[0031] Please see Figure 4-5 Based on embodiment 1, a fixing frame 3, a base 4, and a fixing component 5 are also provided. The fixing frame 3 can stabilize the extraction tank 1, and the fixing frame 3 is connected to the base 4 through the fixing component 5, thereby improving the stability of the fixing frame 3 and thus improving the stability of the extraction tank 1 inside the fixing frame 3.

[0032] Specifically, the fixing frame 3 includes a base frame 301 set at the bottom of the extraction tank 1, and a support plate 301a welded to the top side wall of the base frame 301. A top frame 302 is detachably fixed to the top of the support plate 301a. A base 4 is also set below the fixing frame 3. The base 4 contacts the bottom side wall of the extraction tank 1 through a damper 6. The base 4 is also connected to the fixing frame 3 through a fixing component 5. The fixing component 5 includes positioning rods 502 fixed to the base frame 301 and the base 4. The two positioning rods 502 are fixed together by a traction belt 501.

[0033] Furthermore, the top frame 302 is arranged in a ring structure, and an abutment block 302a is also adhered to the inner bottom side wall of the top frame 302. The top frame 302 contacts the top outer wall of the extraction tank 1 through the abutment block 302a. The support plate 301a contacts the outer wall of the extraction tank 1. The base 4 is provided with a side groove 401 for installing the positioning rod 502, and a counterweight block 402 is also placed on the base 4. A total of four fixing components 5 are provided, and the four fixing components 5 are respectively arranged on the four sides of the base 4. The positioning rod 502 includes a round rod 502c embedded in the inner wall of the side groove 401, and the other end of the round rod 502c is slidably inserted into the rod sleeve 502a. A spring 502b is also provided in the rod sleeve 502a.

[0034] The operation process of this embodiment is as follows: When in use, hold the sleeve 502a and squeeze the round rods 502a at both ends, so that the end of the round rod 502c is compressed into the inside of the sleeve 502a. Align the round rod 502c with the side groove 401 and then release the round rod 502c. At this time, under the push of the spring 502b, the end of the round rod 502c passes into the round hole on the inner wall of the side groove 401. In this way, the other sleeve 502a and the round rod 502c are assembled into the round hole on the bottom side wall between the two support plates 301a. Then, the traction belt 501 is wrapped between the two and tightened. Finally, it is locked by the buckle 501a, which completes the assembly between the base 4 and the fixed frame 3.
