[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to specific embodiments and the accompanying drawings.

[0031] It should be noted that in all the descriptions of the embodiments of the present utility model using "first" and "second", the purpose is to distinguish two entities or parameters with the same name but different, so "first" and "second" are only for the convenience of expression and should not be construed as a limitation to the embodiments of the present utility model. This will not be further explained in the subsequent embodiments.

[0032] In the present utility model, the term "integral structure" means that the main body of the feeding main pipe is a complete pipe, rather than a spliced pipe.

[0033] As Figure 1 shown, the present utility model provides a feeding device for an airflow pulverizer, including an airflow pulverizer 5 and a feeding pipe;

[0034] The feeding pipe includes a feeding main pipe and at least one feeding branch pipe with one end connected to the feeding main pipe;

[0035] The feed main pipe includes a feed main pipe body 1. One end of the feed main pipe body 1 is connected to the air jet mill 5, and the other end is connected to the first feed unit for receiving the material 6 or communicating with the atmosphere. An opening for connecting the feed branch pipe is provided on the feed main pipe body 1;

[0036] The feed branch pipe includes: a feed branch pipe body 2 connected to the opening, a constant flow pump 3, an atomizer 4 provided on the feed branch pipe body 2, and a second feed unit;

[0037] The second feed unit is arranged at the other end of the feed branch pipe body 2 opposite to the end connected with the opening;

[0038] The constant flow pump 3 is arranged downstream of the second feed unit, and the atomizer 4 is arranged downstream of the constant flow pump 3.

[0039] The feed device of the air jet mill provided by the present utility model can enable the material 6 to be vapor pulverized (generally titanium dioxide or other powdery materials to be vapor pulverized) to enter the feed main pipe through the first feed unit, and the organic reagent 7 to enter the feed branch pipe through the second feed unit. The flow rate is adjusted by the constant flow pump 3. Then, after the organic reagent 7 is atomized by the atomizer 4 of the branch pipe, it enters the feed main pipe and enters the inside of the vapor pulverizer together with the material 6. Thus, the steps of feeding and adding the organic reagent 7 are directly completed during the feeding process, and the operation is simple. It is easier to feed the material 6 for vapor pulverization operation. At the same time, the function of accurately adding organic solvents is provided at the air jet mill 5, which simplifies the operation and improves the operation efficiency.

[0040] In addition, in the present utility model, the feed main pipe can be connected to one, two or more feed branch pipes. In some embodiments of the present utility model, the feed main pipe is only connected to one feed branch pipe.

[0041] In some embodiments, the feed branch pipe is made of a leak-proof inert material. For example, it can be a leak-proof stainless steel material. In the present utility model, the organic reagent 7 flows into the feed main pipe through the feed branch pipe and mixes with the material 6 (generally titanium dioxide). Therefore, the material of the feed branch pipe is a leak-proof inert material that does not react with the organic reagent 7, such as a leak-proof rubber material or a leak-proof plastic material.

[0042] In some embodiments, the feed main pipe body 1 is a flexible pipe or a rigid pipe;

[0043] The feed branch pipe body 2 is a flexible pipe or a rigid pipe;

[0044] The feed main pipe body 1 is made of a transparent or opaque material;

[0045] The main body 2 of the feed branch pipe is made of transparent or opaque material.

[0046] In the present utility model, if during the laboratory work, steam pulverization operation is carried out on the material, then the main body 1 of the feed main pipe is a flexible pipe, and at the same time, the main body 2 of the feed branch pipe is a flexible pipe. For example, it can be a rubber pipe. If during the actual production process, steam pulverization operation is carried out on the titanium dioxide experimental material 6, then the main body 1 of the feed main pipe is a rigid pipe, and at the same time, the main body 2 of the feed branch pipe is a rigid pipe, such as a stainless steel pipe.

[0047] In some embodiments, the main body 1 of the feed main pipe is an integral structure. That is, the feed main pipe and the feed branch pipe are of an integral structure. Specifically, the feed main pipe and the feed branch pipe are of a Y-shaped tee structure and are integrally formed.

[0048] In some embodiments, one end of the main body 1 of the feed main pipe is provided with a first connector with threads, and the air jet mill 5 is provided with a first connection port with threads that is connected and adapted to the first connector, and the first connector is threadedly connected to the first connection port.

[0049] In the present utility model, by threadedly connecting one end of the main body 1 of the feed main pipe to the air jet mill 5, it is possible to prevent the material 6 (titanium dioxide) from escaping.

[0050] In some embodiments, the main body 1 of the feed main pipe is a detachable segmented structure, including the first section of the feed main pipe, the first connector, the second section of the feed main pipe, the second connector, the third section of the feed main pipe, and the third connector;

[0051] One end of the first section of the feed main pipe is connected to one end of the air jet mill 5, and the other end is detachably connected to one end of the second section of the feed main pipe through the first connector;

[0052] An opening for connecting the feed branch pipe is provided on the second section of the feed main pipe. The other end of the second section of the feed main pipe is detachably connected to one end of the third section of the feed main pipe through the second connector, and the other end of the third section of the feed main pipe is detachably connected to the first feed unit through the third connector;

[0053] The detachable connection is a threaded connection or a socket connection.

[0054] In the present utility model, by dividing the feed main pipe into three detachable sections, it is convenient to directly replace the damaged section when the main body 1 of the feed main pipe is damaged, rather than replacing the entire feed main pipe, which can reduce the maintenance cost.

[0055] In some embodiments, one end of the feed branch pipe is provided with a second connector with threads, and the second connection port is provided with a threaded structure adapted to the second connector, and the second connector is threadedly connected to the second connection port.

[0056] In some embodiments, along the flow direction of the material 6, the included angle between the main feed pipe and the branch feed pipe is an acute angle (i.e., an angle less than 90 degrees).

[0057] In some embodiments, along the flow direction of the material 6, the angle between the main feed pipe and the branch feed pipe is less than or equal to 80 degrees.

[0058] In some embodiments, the device further includes a main switch (not shown in the figure), and the main switch is electrically connected to the air jet mill 5, the constant flow pump 3, and the atomizer 4 respectively through wires.

[0059] The utility model is provided with a main switch, aiming to turn off the feeding device simultaneously when any one of the air jet mill 5, the constant flow pump 3, and the atomizer 4 fails, so as to avoid the equipment running idly and reduce the service life of the feeding device.

[0060] The use process of the device of the utility model is as follows:

[0061] As Figure 1 shown, start the air jet mill 5. The air jet mill automatically sucks materials by the negative pressure inside the air jet mill 5, creating a negative pressure inside both the main feed pipe and the branch feed pipe. Under the action of the negative pressure, the main feed pipe sucks the material 6. At the same time, start the constant flow pump 3, set an appropriate flow rate, and suck the organic reagent 7. Then, the organic reagent 7 enters the atomizer 4 through the constant flow pump 3 for atomization. The atomized liquid droplets of the organic reagent converge with the material 6 in the main feed pipe and enter the inside of the air jet mill 5 under the action of the negative pressure for further grinding.

[0062] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above-described embodiments only represent several implementation manners of the utility model, and their descriptions are relatively specific and detailed. However, it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
