[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1:

[0028] Reference Figure 1-5 The veterinary drug spray dryer includes a body 1, a heating chamber 2, a collecting and separating chamber 3, and an air pump 4. The body 1 is connected to a feed port 101, and the outlet end of the heating chamber 2 is connected to an outlet pipe 1, the outlet pipe is connected to the feed port 101, and the air inlet end of the heating chamber 2 is connected to a filter plate 204. The air pump 4 is installed on the body 1, and the outlet end of the air pump 4 is connected to an outlet pipe 2. The feed end and the discharge end of the collecting and separating chamber 3 are respectively connected to a connecting pipe 302 and a discharge port 301. The connecting pipe 302 is connected to the discharge end of the body 1, and the air inlet end of the air pump 4 is connected to the collecting and separating chamber 3. It also includes: an extension pipe 5, connected to the outlet end of the heating chamber 2; a sub-pipe 401, and the sub-pipe 401 is connected to the outlet pipe 2; a preheating pipe 402, connected to It is connected to the air outlet end of the auxiliary pipe 401, and the preheating pipe 402 is located in the extension pipe 5; the knocking component is connected to the air outlet end of the preheating pipe 402, and the knocking component is used to generate vibration to knock off the dust on the filter plate 204. The knocking component includes a tube body 601, a spring part 602, a piston rod 603, and an air release port 604. The tube body 601 is fixedly connected to the preheating pipe 402, and the spring part 602 is fixedly connected in the tube body 601. The piston rod 603 is slidably connected in the tube body 601 and is connected to one end of the spring part 602. The air release port 604 is arranged in the piston rod 603, and an electronic valve is installed in the air release port 604. A knocking rod 605 is fixedly connected to the piston rod 603, and the knocking rod 605 is used to knock the extension pipe 5.

[0029] The air vent 604 in this device is located above the extension tube 5 to prevent the exhausted gas from re-entering the body 1.

[0030] When in use, turn on the air pump 4 and the heating chamber 2, and then put the veterinary medicine into the feed port 101 of the body 1. The centrifugal atomizer in the feed port 101 will turn the veterinary medicine into granular atomized veterinary medicine during rapid rotation. At the same time, the hot air generated by the heating chamber 2 will quickly come into contact with the atomized veterinary medicine, thereby achieving drying. The dried veterinary medicine will enter the collection and separation chamber 3 together with the gas through the connecting pipe 302. At this time, the gas will enter the air pump 4 for discharge, and the veterinary medicine will be discharged through the discharge port 301.

[0031] As the hot gas is discharged, the hot gas will enter the preheating tube 402 through the auxiliary pipe 401, and the preheating tube 402 will gradually be heated. At this time, the gas entering the extension tube 5 will first pass through the preheating tube 402 and be preheated. At the same time, the gas will eventually enter the tube body 601. As the air pressure continues to increase, the piston rod 603 will move in the tube body 601, thereby pulling the spring part 602 to lengthen and making the knocking rod 605 move away from the extension tube 5. Subsequently, as the air pressure increases, the electronic valve detects the pressure change. After reaching the threshold, that is, the displacement limit of the piston rod 603 is about to be reached, the electronic valve opens, the gas is quickly discharged, the spring part 602 will drive the piston rod 603 to reset, and the knocking rod 605 will knock on the extension tube 5, generating vibration, which will be transmitted to the filter plate 204. The impurities on the filter plate 204 will be loosened, and some impurities will fall off, or fall off naturally after shutdown, making it convenient for next use.

[0032] In this way, heat can be more fully utilized, and at the same time, vibration can loosen impurities on the filter plate 204, making it easier for the impurities to fall off naturally, so that the filter plate 204 remains ventilated.

[0033] Example 2:

[0034] Reference Figure 1-5 The veterinary drug spray dryer is basically the same as that in Example 1, and furthermore, a pad 502 is fixedly connected to the extension tube 5.

[0035] The provision of the pad 502 facilitates increasing the service life of the striking position.

[0036] Example 3:

[0037] Reference Figure 1-5 , the veterinary drug spray dryer is basically the same as Example 1, furthermore: a heating tube 201 and an air hole 202 are provided in the heating chamber 2, a mounting plate 203 is fixedly connected to the heating chamber 2, a filter plate 204 is installed on the mounting plate 203, a mounting pressure plate 205 is connected to the filter plate 204, and a mounting bolt 501 is connected to the extension tube 5.

[0038] The arrangement of the mounting plate 203 and the mounting pressure plate 205 facilitates the installation of the filter plate 204 , and the mounting bolts 501 facilitate the installation of the extension tube 5 on the heating chamber 2 .

[0039] The utility model can effectively reuse the exhausted gas and preheat the gas before heating by setting the preheating tube 402 and the knocking component. At the same time, the gas can also vibrate the filter plate 204, which can shake off impurities on the filter plate 204, making it convenient for long-term use.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
