[0002] PVB resin is a product of the condensation of polyvinyl alcohol and butyraldehyde. It has both adhesive and solubility properties. In the production process of PVB resin, it is most commonly made into resin granules so that the resin can be used later. After the PVB resin granules are produced, they are dried to reduce their internal moisture, thereby reducing the impact on subsequent processing.

[0003] During the drying process of PVB resin, the moisture in the resin particles causes them to stick together, which affects the drying process and the drying effect, resulting in the dried product failing to meet the required specifications. To solve this problem, there is an urgent need for a drying device for PVB resin manufacturing. Utility Model Content

[0004] The purpose of this invention is to solve the problem that during the drying process of PVB resin, the resin particles contain moisture, which causes the resin particles to stick together, thus affecting the drying process and the drying effect, resulting in the dried product not meeting the required standards. Therefore, this invention provides a drying device for PVB resin manufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for manufacturing PVB resin, comprising a drying tank, a cover plate on the top surface of the drying tank, a first wedge block fixedly installed on the bottom surface inside the drying tank, a stirring assembly inside the drying tank, and a ventilation assembly on one side of the drying tank.

[0006] The stirring assembly includes a motor, an installation rod is fixedly mounted on the output shaft of the motor, a stirring rod is fixedly mounted on the outer wall of the installation rod, an air jet disc is slidably mounted on the installation rod through its bottom end, a first connecting sleeve is fixedly mounted on the top surface of the air jet disc, a second wedge is fixedly mounted on the bottom surface of the air jet disc, a second connecting sleeve is fixedly mounted on the bottom surface of the air jet disc, and a spring is fixedly mounted on the top surface of the air jet disc.

[0011] As a further description of the above technical solution:

[0012] The inclined surface of the second wedge is positioned opposite to the inclined surface of the first wedge, and the outer wall of the jet disc is in contact with the inner wall of the drying tank.

[0013] As a further description of the above technical solution:

[0014] The ventilation assembly includes an air pump, one end of which is fixedly mounted with a first delivery pipe, and the other end of which is fixedly mounted with an air collection hood.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, a stirring rod is installed inside. During the drying process of PVB resin particles, the motor is started to drive the mounting rod to rotate and drive the stirring rod to stir. The rotation of the stirring rod knocks apart the clumps of resin particles. At the same time, the airflow sprayed by the jet disk moves the resin particles. The rotation of the mounting rod can drive the jet disk to rotate, and under the action of the first wedge and the second wedge, the jet disk can be raised, causing the spring to compress. As the second wedge separates from the first wedge, the spring drives the jet disk and the second wedge to descend. This design enables the resin particles to be struck by the rotation of the stirring rod during the drying process, thereby quickly separating clumps of resin and ensuring the drying effect of the resin particles. The airflow emitted by the jet plate can also drive the resin particles to flow quickly and reduce the contact time between the resin particles, thus preventing the resin particles from clumping again. At the same time, the jet plate rotates with the rotation of the mounting rod, and the first and second wedges can make the jet plate swing up and down, thereby changing the effect of the jet plate by changing its position.

[0023] 2. In this utility model, by incorporating an air pump, during the drying process, the air pump can be activated to draw gas from the top of the drying tank into the second connecting sleeve and then into the jet plate for ejection. Furthermore, the gas in the first conveying pipe can be purified by a purification module. Through this design, the air pump can drive the airflow inside the drying tank to circulate and eject from the jet plate during the drying process, thereby improving the drying effect. Additionally, the purification module can purify the harmful gases generated in the first conveying pipe due to resin heating, thus preventing harmful gases from harming the environment.

[0030] 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.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a drying device for manufacturing PVB resin, including a drying tank 1, a cover plate 2 on the top surface of the drying tank 1, a first wedge block 5 fixedly installed on the bottom surface inside the drying tank 1, a stirring assembly 3 inside the drying tank 1, and a ventilation assembly 4 on one side of the drying tank 1.

[0032] The stirring assembly 3 includes a motor 31, with a mounting rod 32 fixedly mounted on the output shaft of the motor 31. A stirring rod 33 is fixedly mounted on the outer wall of the mounting rod 32. An air jet disk 36 is slidably mounted on the mounting rod 32 through its bottom end. A first connecting sleeve 35 is fixedly mounted on the top surface of the air jet disk 36. A second wedge block 37 is fixedly mounted on the bottom surface of the air jet disk 36. A second connecting sleeve 38 is fixedly mounted on the bottom surface of the air jet disk 36. A spring 34 is fixedly mounted on the top surface of the air jet disk 36.

[0033] One end of the motor 31 is fixedly connected to the cover plate 2, the mounting rod 32 is rotatably connected to it through a through hole in the cover plate 2, the other end of the spring 34 is fixedly connected to the mounting rod 32, the spring 34 is located in a groove at the bottom end of the mounting rod 32, the inner wall of the first connecting sleeve 35 is slidably connected to the mounting rod 32, the inclined surface of the second wedge 37 is opposite to the inclined surface of the first wedge 5, and the outer wall of the jet disc 36 is in contact with the inner wall of the drying tank 1.

[0034] The specific implementation method is as follows: During the drying process of PVB resin particles, the resin is put into the drying tank 1 through the feed pipe provided on the top surface of the cover plate 2, and the motor 31 is started, thereby driving the mounting rod 32 to rotate and driving the stirring rod 33 to stir. The rotation of the stirring rod 33 knocks the clumps of resin particles to separate them. At the same time, the air jet 36 sprays air to move the resin particles. The rotation of the mounting rod 32 can drive the air jet 36 to rotate through the notch below the mounting rod 32, and drive the air jet to move. The second wedge 37 below the disk 36 moves. When the second wedge 37 moves to a certain position, the inclined surface of the second wedge 37 contacts the inclined surface of the first wedge 5. As the second wedge 37 continues to move, it gradually rises along the inclined surface of the first wedge 5, causing the jet disk 36 to rise and the spring 34 to be compressed. When the second wedge 37 separates from the first wedge 5, the spring 34 causes the jet disk 36 and the second wedge 37 to fall, and the second wedge 37 re-contacts the ground inside the drying tank 1.

[0035] The ventilation assembly 4 includes an air pump 45. A first delivery pipe 43 is fixedly installed at one end of the air pump 45. A gas collection hood 42 is fixedly installed at one end of the first delivery pipe 43. One side of the gas collection hood 42 is fixedly connected to the drying tank 1. A filter screen 41 is fixedly installed on one side of the gas collection hood 42. A purification module 44 is provided on the outer wall of the first delivery pipe 43. A second delivery pipe 47 is fixedly installed at the other end of the air pump 45. A connecting pipe 46 is fixedly installed at one end of the second delivery pipe 47. The connecting pipe 46 passes through the bottom of the drying tank 1 and is fixedly connected to the drying tank 1. The connecting pipe 46 is rotatably connected to the second connecting sleeve 38.

[0036] The specific implementation method is as follows: During the drying process, the air pump 45 can be started and the gas at the top of the drying tank 1 can be drawn into the second connecting sleeve 38 through the first conveying pipe 43, the second conveying pipe 47 and the connecting pipe 46 and sprayed out into the jet plate 36. At the same time, the filter screen 41 can be used to prevent resin particles from entering the air pump 45 and causing an impact, and the gas in the first conveying pipe 43 can be purified by the purification module 44.

[0037] Working principle: During the drying process of PVB resin particles, the resin is put into the drying tank 1 through the feed pipe on the top surface of the cover plate 2. The motor 31 is started, which drives the mounting rod 32 to rotate and drives the stirring rod 33 to stir. The rotation of the stirring rod 33 knocks the clumps of resin particles to separate them. At the same time, the air pump 45 can be started to draw the gas from the top of the drying tank 1 into the second connecting sleeve 38 through the first conveying pipe 43, the second conveying pipe 47 and the connecting pipe 46 and spray it into the jet plate 36. At the same time, the filter screen 41 can prevent resin particles from entering the air pump 45 and affecting it. The purification module 44 can purify the first conveying pipe 43. The gas inside is purified, and the rotation of the mounting rod 32 can drive the jet disk 36 to rotate through the notch below the mounting rod 32, and drive the second wedge 37 below the jet disk 36 to move. At the same time, when the second wedge 37 moves to a certain position, the inclined surface of the second wedge 37 contacts the inclined surface of the first wedge 5. As the second wedge 37 continues to move, it gradually rises along the inclined surface of the first wedge 5, driving the jet disk 36 to rise, and at the same time, the spring 34 is compressed. When the second wedge 37 separates from the first wedge 5, the spring 34 drives the jet disk 36 and the second wedge 37 to fall, and the second wedge 37 re-contacts the ground inside the drying tank 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
