Description

Technical Field

[0001] The utility model relates to the technical field of decabromodiphenylethane production, in particular to a wet automatic feeding device for EDTA-2Na in the production process of decabromodiphenylethane. Background Technique

[0002] In the production process of decabromodiphenylethane, EDTA-2Na (disodium ethylenediaminetetraacetate) serves as an important complexing agent and plays a crucial role. EDTA-2Na can effectively form stable complexes with metal ions, thereby preventing the interference of metal ions on the reaction. This complexing agent needs to be added accurately and timely according to the changes in reaction conditions during the production process to ensure the smooth progress of the reaction and the high purity of the final product.

[0003] Traditional manual feeding methods have many problems in industrial production. First of all, this method usually requires operators to perform manual operations at the production site. Not only is the labor intensity high, but the operation process often requires long-term physical labor, which is prone to fatigue. Fatigued operators may have problems such as inattentiveness or non-standard operations, increasing the risk of inaccurate feeding. Secondly, due to factors such as personnel experience, operating environment, and the accuracy of weighing tools, it is difficult to ensure that the amount of materials added each time is exactly the same. This inconsistency will not only lead to incomplete reactions or increased side reactions, but also affect the quality and consistency of the product.

[0004] Therefore, it is necessary to provide a wet automatic feeding device for EDTA-2Na in the production process of decabromodiphenylethane to solve the above technical problems. Content of the Utility Model

[0037] The working principle of the present utility model is as follows: all the electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technologies are not elaborated in the text. The parts not involved in this device are the same as the prior art or can be implemented using the prior art. When in use, first control the first motor 10 to start working. The driving end of the first motor 10 drives the threaded rod 17 to rotate. Through the threaded transmission between the threaded rod 17 and the adjusting block 26, and the sliding relationship between the adjusting block 26 and the slideway 6, the adjusting block 26 moves vertically stably. The movement of the adjusting block 26 drives the mounting plate 8 to move. The movement of the mounting plate 8 drives the electric telescopic rod 7 to move. The movement of the electric telescopic rod 7 drives the feeding box body 13 to move. Therefore, through the drive of the first motor 10, the vertical movement of the feeding box body 13 can be realized. The feeding box body 13 is moved downward to a position where the staff can easily reach. Then, a certain proportion of EDTA-2Na and water are added into the feeding box body 13 through the feeding pipe 11 to form an aqueous solution of EDTA-2Na. Then, control the feeding box body 13 to move up to the specified height, and through the rolling contact of the universal wheels 2 with the ground, move the device to the side of the decabromodiphenylethane production reaction equipment. At the same time, control the electric telescopic rod 7 to start working. The driving end of the electric telescopic rod 7 drives the feeding box body 13 to move horizontally, so that the feeding pipe 16 at the bottom of the feeding box body 13 moves above the feeding end of the reaction equipment. Then, control the vertical movement of the feeding box body 13 to insert the bottom end of the feeding pipe 16 into the inside of the feeding end. Subsequently, control the electric valve 22 and the electronic flowmeter 23 to start working. After the electric valve 22 is opened, the EDTA-2Na aqueous solution inside the feeding box body 13 is added into the reaction equipment through the feeding pipe 16. During the process of the aqueous solution passing through the inside of the feeding pipe 16, the electronic flowmeter 23 will monitor the flow rate of the aqueous solution in real time. When the added amount is reached, the electronic flowmeter 23 will send a signal to the main controller to control the electric valve 22 to close, achieving precise feeding. Throughout the feeding process, it is all automatically completed by this device, avoiding the non-standard operation of manual feeding, improving the feeding efficiency and safety, ensuring the quality and consistency of the product, and through the mobility of the device, as well as the vertical and horizontal movement of the feeding box body 13, enabling the device to be better matched with different reaction equipment, improving the flexibility of the device.

[0038] After adding EDTA-2Na and water into the feeding box body 13 in a certain proportion, the second motor 12 can be controlled to start working. The driving end of the second motor 12 drives the stirring shaft 18 to rotate. The rotation of the stirring shaft 18 drives the stirring roller 19 to rotate. The rotation of the stirring roller 19 stirs the materials inside the feeding box body 13. At the same time, the heating plate 21 is controlled to start working. The heating plate 21 heats the materials inside the feeding box body 13. Cooperating with the temperature sensor 20, the temperature of the solution inside the feeding box body 13 can be monitored in real time, realizing the stirring, heating and temperature monitoring of the materials added into the feeding box body 13, ensuring the complete dissolution of EDTA-2Na and water, and the uniformity of EDTA-2Na during the feeding process, preventing caking, and further improving the quality and consistency of the product.
