It can be seen that this way of discharging materials requires re-weighing to determine the quality of the materials after they are discharged, and then the materials are packaged. This unloading method of the dryer adds an extra packaging process, which reduces the efficiency of packaging materials after the dryer dries the materials. Utility Model Content

[0020] Reference Figure 1-4 A quantitative unloading dryer comprises a base 1 and a dryer body 5, a discharge pipe 6 is fixedly arranged at the bottom of the dryer body 5, and an electric butterfly valve 7 is fixedly arranged at the middle position of the discharge pipe 6; a conveying assembly is connected to the bottom of the discharge pipe 6, and the conveying assembly comprises a conveying pipeline 9, and a connecting pipe 8 is connected to the top of one end of the conveying pipeline 9, and the connecting pipe 8 is slidably sleeved on the outside of the discharge pipe 6, and the length of the discharge pipe 6 inserted into the connecting pipe 8 is greater than three quarters of its total length, and the diameter of the discharge pipe 6 is smaller than the diameter of the connecting pipe 8. A discharge pipe 14 is connected to the bottom of the conveying pipeline 9 away from the discharge pipe 6; a weighing assembly is arranged at the bottom of the conveying assembly, and the weighing assembly is located between the base 1 and the conveying assembly.

[0021] The conveying assembly also includes a fixed frame 10 arranged on the left side of the conveying pipeline 9, and a driving motor 11 is fixedly arranged at the end of the fixed frame 10. The output end of the driving motor (11) passes through the fixed frame (10) and extends into the conveying pipeline (9). The output end of the driving motor 11 is fixedly connected to a conveying screw 12, and the conveying screw 12 is located in the conveying pipeline 9. The driving motor 11 drives the conveying screw 12 to rotate in the conveying pipeline 9, and a spiral blade 13 is fixedly arranged on the surface of the conveying screw 12. The output end of the driving motor 11 drives the conveying screw 12 to rotate, and the spiral blade 13 is driven to rotate by the conveying screw 12, so that the material entering the conveying pipeline 9 is easily transported.

[0022] The weighing assembly includes a support plate 15 arranged at the bottom of the conveying pipe 9, a support column 16 is fixedly arranged at the bottom of the support plate 15, a connecting plate 17 is fixedly arranged at the bottom of the support column 16, a connecting column 18 is fixedly arranged at the bottom of the connecting plate 17, and the weighing assembly also includes a weighing sensor 19, the number of which is four, and the four weighing sensors 19 are centrally symmetrically distributed, the weighing sensor 19 is fixedly mounted on the top of the base 1, and the connecting column 18 is fixedly mounted on the top of the weighing sensor 19. The support plate 15 is fixedly mounted on the surface of the conveying pipe 9, the support column 16 is fixedly mounted on the surface of the support plate 15, the connecting plate 17 is mounted at the bottom of the support column 16, and is mounted on the top of the weighing sensor 19 through the connecting column 18 at the bottom of the connecting plate 17, so as to facilitate the installation of the conveying pipe 9, and facilitate the installation of the conveying pipe 9 on the top of the weighing sensor 19, so as to facilitate the weight of the material entering the conveying pipe 9.

[0023] The support plate 15 is in a semicircular structure and is made of metal. There are two support plates 15 . The semicircular support plate 15 fits more closely with the delivery pipe 9 , making the delivery pipe 9 more stably installed.

[0024] A mounting frame assembly is provided on the top of the base 1, and the mounting frame assembly includes a mounting column 2 provided on the top of the base 1, a mounting plate 3 is fixedly provided on the top of the mounting column 2, a mounting opening 4 is provided through the top of the mounting plate 3, a dryer body 5 is detachably provided at the mounting opening 4, and the dryer body 5 is installed inside the mounting opening 4, the mounting column 2 is fixedly installed on the top of the base 1, and the mounting plate 3 is fixedly installed on the top of the mounting column 2, and the dryer body 5 is fixedly installed inside the mounting opening 4, so as to facilitate the installation of the dryer body 5. The components used in the present application to enable the dryer to have a quantitative unloading function are a conveying component, a weighing component and a mounting frame assembly. Since the dryer body is detachably mounted on the mounting frame assembly, the structure of the quantitative unloading part can also be separated from the dryer body 5. At this time, the dryer body 5 is detached from the mounting opening 4, and the discharge pipe 6 is separated from the connecting pipe 8. The part that realizes quantitative unloading is then connected to other devices (such as a mixing device, etc.) to realize the quantitative unloading process of other devices.

[0025] There are four mounting columns 2, and the four mounting columns 2 are distributed at the four corners of the top of the base 1. The mounting columns 2 are made of metal. The four mounting columns 2 make the mounting plate 3 more firmly installed, thereby making the dryer body 5 more firmly installed.

[0026] In the quantitative unloading dryer, when the dryer body 5 has finished drying the material, the electric butterfly valve 7 provided on the discharge pipe 6 is opened, and the dried material in the dryer body 5 enters the connecting pipe 8 through the discharge pipe 6, and enters the inside of the conveying pipe 9 through the connecting pipe 8. Since the material has its own weight, the sleeve length of the discharge pipe 6 and the connecting pipe 8 can avoid a large amount of flying material when the material enters the connecting pipe 8 from the discharge pipe 6 to a certain extent, and the additional material splashing from the connection is less, which will not affect the quality of the material entering the conveying pipe 9. When the applicant uses the device, a sealing tape is wound around the connection between the discharge pipe 6 and the connecting pipe 8 for sealing. Since the existing sealing tape is light in weight and there is a surplus of the sealing tape adhering to the discharge pipe 6 and the connecting pipe 8 during winding, the sealing tape wound around the connection will not affect the weight of the material transported by the conveying pipe 9. The material entering the conveying pipe 9 is moved by the conveying component, and at the same time, the conveying pipe 9 applies pressure to the weighing sensor 19 through the weighing component, and the material entering the conveying pipe 9 is weighed by the weighing sensor 19. When the material entering the conveying pipe 9 reaches the weight, the electric butterfly valve 7 is closed, and the material is transported to the discharge pipe 14 through the conveying component, and the dried material is discharged through the discharge pipe 14, thereby achieving the goal of facilitating the quantitative discharge of the material dried by the dryer, avoiding the situation where the material dried by the dryer is discharged at one time and the subsequent need for re-quantification is avoided, thereby making the dryer more convenient to use.

[0027] The electrical components appearing in this article are all electrically connected to an external main controller and factory wires, and the main controller can be a conventional known device such as a computer or PLC for control.

[0028] When in use: after the dryer body 5 has finished drying the material, the electric butterfly valve 7 provided on the discharge pipe 6 is opened. The electric butterfly valve 7 is a common powder conveying valve obtained through purchase. The dried material in the dryer body 5 enters the connecting pipe 8 through the discharge pipe 6, and enters the inside of the conveying pipe 9 through the connecting pipe 8. The output end is driven by the driving motor 11 provided in the conveying assembly to drive the conveying screw 12 to rotate, and the spiral blade 13 is driven by the conveying screw 12 to rotate, so that the material entering the conveying pipe 9 is moved. When the material enters the conveying pipe 9, the weight of the entire conveying pipe increases when the material enters the conveying pipe. The material entering the conveying pipe 9 is weighed by the weighing sensor 19 (the weighing sensor 19 is a common sensor, also obtained through purchase). When the material entering the conveying pipe 9 reaches the weight, the electric butterfly valve 7 is closed, and the output end is driven by the driving motor 11 to drive the conveying screw 12 to rotate. The conveying screw 12 drives the spiral blade 13 to rotate, and the dried material is conveyed to the discharge pipe 14 by the spiral blade 13, and the dried material is discharged through the discharge pipe 14.

[0029] To sum up, in the quantitative unloading dryer, when the dryer body 5 has finished drying the material, the electric butterfly valve 7 provided on the discharge pipe 6 is opened, and the dried material in the dryer body 5 enters the connecting pipe 8 through the discharge pipe 6, and enters the inside of the conveying pipe 9 through the connecting pipe 8, and the material entering the conveying pipe 9 is moved by the conveying component, and at the same time, the conveying pipe 9 applies pressure to the weighing sensor 19 through the weighing sensor 19, and the material entering the conveying pipe 9 is weighed by the weighing sensor 19. When the material entering the conveying pipe 9 reaches the weight, the electric butterfly valve 7 is closed, and the material is conveyed to the discharge pipe 14 through the conveying component, and the dried material is discharged through the discharge pipe 14, thereby achieving the goal of facilitating the quantitative unloading of the material dried by the dryer, avoiding the situation where the material dried by the dryer is discharged at one time and the subsequent need for re-quantification is avoided, thereby making the dryer more convenient to use and being used to solve the problems raised in the above-mentioned background technology.
