Description

Technical Field

[0001] The utility model relates to the technical field of material adding equipment, in particular to a powder material feeding system. Background Art

[0002] In the chemical reaction process, it is necessary to add powder materials into the reaction vessel. During the process of adding powder materials, the powder materials will not immediately contact with the solvent in the reaction vessel after entering the reaction vessel. Dust is often generated during the process of falling into the solvent. These dusts may leak out through the adding port, causing harm to the operators. At the same time, a large amount of dust will adhere to the inner wall of the upper end of the reaction vessel (the part above the solvent liquid level line), and cannot smoothly participate in the reaction system, which is not conducive to the full reaction of the materials and also affects the overall product yield. Therefore, in the actual operation process, in order to avoid dust leakage, the feeding speed of the powder materials is relatively low, but there is still dust adhering to the inner wall of the reaction vessel and cannot smoothly participate in the reaction system. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a powder material feeding system, which solves the problem that dust adheres to the inner wall of the reaction vessel and cannot smoothly participate in the reaction system in the prior art.

[0004] According to an embodiment of the utility model, a powder material feeding system includes:

[0005] An adsorption tank, the adsorption tank is communicated with the reaction vessel through a first connecting pipe, and a first pump body is arranged on the first connecting pipe to pump the solvent in the reaction vessel into the adsorption tank;

[0006] An adsorption pipe, one end of the adsorption pipe is communicated with the adsorption tank, the other end is communicated with the reaction vessel, and the adsorption pipe extends to the inner bottom of the adsorption tank;

[0007] A spray pipe, the spray pipe is fixedly arranged at the upper end inside the reaction vessel, and the spray pipe is communicated with the adsorption tank through a second connecting pipe;

[0008] The adsorption tank is also connected with a vacuum pumping device and a pressurizing device.

[0009] In the above embodiment, the arranged adsorption tank adsorbs the dust into the adsorption tank first, mixes it with the solvent in the adsorption tank first, and then introduces it into the reaction vessel in a spray manner. When spraying, the inner wall of the reaction vessel can be washed, so that the generated dust can return to the reaction vessel to a greater extent and participate in the reaction system, solving the problem that dust adheres to the inner wall of the reaction vessel and cannot smoothly participate in the reaction system in the prior art.

[0010] Further, the spray pipe includes a horseshoe-shaped mounting pipe horizontally arranged at the upper end inside the reaction vessel. A number of spray heads are mounted on the lower wall surface of the mounting pipe, and one end of the second connecting pipe away from the adsorption tank is fixedly connected to the mounting pipe.

[0011] Further, the outlet of the spray head faces outward of the horseshoe shape and inclines downward.

[0012] Further, one end of the adsorption pipe away from the adsorption tank is located above the mounting pipe.

[0013] Further, the adsorption pipe is also connected to a cover cylinder located above the mounting pipe. The cover cylinder is vertically arranged with a larger lower part and a smaller upper part.

[0014] Further, a confluence pipe is fixedly connected to the bottom of the adsorption tank. The first connecting pipe and the second connecting pipe are connected to the confluence pipe through a three-way valve.

[0015] Further, a second pump body is also mounted on the second connecting pipe.

[0016] Further, the adsorption tank is connected to a pressurizing device and a vacuum pumping device through a third connecting pipe and a fourth connecting pipe respectively.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] First, part of the dust is adsorbed by the adsorption tank and mixed into the solvent therein, and then it is introduced into the reaction vessel in a spraying manner. When spraying, the inner wall of the reaction vessel can be washed, so that the generated dust can return to the reaction vessel to a greater extent and participate in the reaction system, solving the problem in the prior art that the dust adheres to the inner wall of the reaction vessel and cannot smoothly participate in the reaction system.

Therefore, it should not be construed as a limitation to the present utility model.

[0025] In an exemplary embodiment, as Figure 1 , 2 shown, this embodiment provides a powder material feeding system, which includes:

[0026] An adsorption tank 1, the adsorption tank 1 is communicated with a reaction vessel 3 through a first connecting pipe 2, and a first pump body 4 is arranged on the first connecting pipe 2 to pump the solvent in the reaction vessel 3 into the adsorption tank 1;

[0027] An adsorption pipe 5, one end of the adsorption pipe 5 is communicated with the adsorption tank 1 and the other end is communicated with the reaction vessel 3, and the adsorption pipe 5 extends to the inner bottom of the adsorption tank 1;

[0028] A spray pipe, the spray pipe is fixedly arranged at the upper end inside the reaction vessel 3, and the spray pipe is communicated with the adsorption tank 1 through a second connecting pipe 6;

[0029] The adsorption tank 1 is also connected with a vacuum pumping device and a pressurizing device, and the adsorption tank 1 is respectively connected with the pressurizing device and the vacuum pumping device through a third connecting pipe 7 and a fourth connecting pipe 8.

[0030] In the above embodiment, the adsorption tank 1 is used to first adsorb the dust into the adsorption tank 1, mix it with the solvent in the adsorption tank 1, and then introduce it into the reaction container 3 in a spraying manner. The inner wall of the reaction container 3 can be flushed during the spraying, so that the generated dust can be returned to the reaction container 3 to a greater extent to participate in the reaction system, which solves the problem in the prior art that the dust adheres to the inner wall of the reaction container 3 and cannot smoothly participate in the reaction system; at the same time, the feeding speed of the powder material in this scheme can also be appropriately increased, and the specific operation When the adsorption tank 1 is charged, part of the solvent is first pumped into the adsorption tank 1 through the first pump body 4, so that the liquid level of the solvent is close to the end of the adsorption tube 5 located in the adsorption tank 1, and then the feeding is started. The setting of the feeding port is similar to that in the prior art, which is set at the top of the reaction vessel 3. While feeding, the vacuum device is started to generate negative pressure in the adsorption tank 1, so that the generated dust can enter the adsorption tube 5 and then be sucked into the adsorption tank 1. The distance between the end of the adsorption tube 5 and the solvent is very close, and the dust can quickly contact with the solvent and mix into the solvent. After the feeding is completed, the vacuum device is closed. The vacuum device is closed, and the pressurizing device is started. The solvent mixed with dust is pressed into the second connecting pipe 6 by pressurizing, and then enters the spray pipe and is introduced into the reaction container 3 in a spraying manner. Specifically, the spray pipe includes a horseshoe-shaped mounting pipe 9 horizontally arranged at the upper end of the reaction container 3, and a plurality of spray heads 10 are installed on the lower wall of the mounting pipe 9. The end of the second connecting pipe 6 away from the adsorption tank 1 is fixedly connected to the mounting pipe 9. These spray heads 10 are installed on the mounting pipe 9, and the outlet can also be oriented outside the horseshoe and tilted downward, so that more alignment can be achieved. The inner wall of the reaction container 3 is flushed during spraying. More specifically, the end of the adsorption tube 5 facing away from the adsorption tank 1 is located above the mounting tube 9, or it can be located below the mounting tube 9. However, it is best to be away from the feeding port and located below the feeding port to avoid directly sucking in the powder material. In particular, the horseshoe-shaped mounting tube 9 can also be appropriately away from the feeding port to avoid the powder material falling directly onto the mounting tube 9 during feeding. A spray head 10 can also be added to the upper wall of the mounting tube 9 to flush the inner top surface of the reaction container 3.

[0031] In further detail, the adsorption tube 5 is also connected to a cover tube 11 located above the mounting tube 9. The cover tube 11 is vertically arranged and is larger at the bottom and smaller at the top, so that the generated dust can be better captured; further, a second pump body 12 can be arranged on the second connecting tube 6, specifically a booster pump, which can assist the pressurizing equipment to make the solvent mixed with dust more smoothly introduced into the spray head 10 and then introduced into the reaction container 3 in a spraying manner.

[0032] In a further exemplary embodiment, Figure 1 , 2As shown in the figure, a confluence pipe 13 is fixedly connected to the bottom of the adsorption tank 1. The first connecting pipe 2 and the second connecting pipe 6 are connected to the confluence pipe 13 through a three-way valve 14. The on-off of the first connecting pipe 2 and the second connecting pipe 6 is controlled by the three-way valve 14. When the first pump body 4 operates, the first connecting pipe 2 is communicated with the confluence pipe 13. When the second pump body 12 operates, the second connecting pipe 6 is communicated with the confluence pipe 13. In this solution, a transparent viewing window 15 can also be arranged on the adsorption tank 1. After the feeding is completed, it can be observed whether there is dust adhering to the inner wall of the adsorption tank 1. If so, more solvent can be first pumped into the adsorption tank 1 through the first pump body 4. The solvent in the reaction vessel 3 is much more than the volume of the adsorption tank 1. Therefore, the adsorption tank 1 can be filled with solvent, so that the dust can be mixed first, and then the solvent mixed with the dust can be returned to the reaction vessel 3 in a spraying manner.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
