Description

Technical Field

[0019] Furthermore, the lifting assembly 18 includes a lifting box 29, which is fixed on the base plate 14, and an oil delivery port 32 is provided on one side of the lifting plate 30. A lifting plate 30 is slidably provided in the lifting box 29, and a spring is provided between the lifting plate 30 and the inner wall of the lifting box 29. A lifting seat 31 is provided on the top of the lifting plate 30, and the lifting seat 31 passes through the top wall of the oil delivery port 32, and the lifting seat 31 abuts against the storage tank 17; the lifting plate 30 is externally connected to a liquid pump and an oil tank through the oil delivery port 32. When the liquid pump pumps hydraulic oil into the lifting box 29, the lifting plate 30 and the lifting seat 31 rise, thereby pushing the storage tank 17 against the discharge port 16. At this time, the spring between the lifting plate 30 and the lifting box 29 is in a stretched state. When the liquid pump extracts the hydraulic oil in the lifting box 29, the lifting plate 30 and the lifting seat 31 move downward under the action of the spring, and the storage tank 17 moves downward accordingly, thereby separating the docking pipe 27 from the discharge port 16.

[0020] Furthermore, a sealing gasket 28 is provided on the butt joint 27 , and the sealing gasket 28 is in contact with the bottom of the discharge port 16 ; when the storage tank 17 is against the discharge port 16 , the sealing gasket 28 is tightly attached to the bottom of the discharge port 16 , thereby enhancing the sealing performance of the connection between the discharge port 16 and the butt joint 27 .

[0021] Furthermore, the control assembly 13 includes a control slider 19 and a cross bar 22, the cross bar 22 is fixed in the discharge tank 11, the control slider 19 is slidably set on the cross bar 22, a closing plate 21 is slidably provided in the receiving port 12, and a connecting rod 20 is connected between the closing plate 21 and the control slider 19; when the closing plate 21 is in the receiving port 12, the closing plate 21 closes the receiving port 12, and when discharging, the control slider 19 is controlled to slide along the cross bar 22 so that the closing plate 21 moves accordingly, and when the closing plate 21 is detached from the receiving port 12, the receiving port 12 is opened, and the material can enter the discharge tank 11 through the receiving port 12, and after the discharging is completed, the control slider 19 is controlled to move and reset, and the closing plate 21 moves accordingly and slides into the receiving port 12, and during the sliding process of the closing plate 21 in the receiving port 12, the residual material in the receiving port 12 can be pushed out to prevent the residual material from blocking the receiving port 12.

[0022] Furthermore, a motor 26 is provided on the inner wall of the discharge tank 11, and a rotating shaft 25 is connected to the output shaft of the motor 26. The rotating shaft 25 is rotatably connected to the inner wall of the discharge tank 11, and a gear 24 is provided on the rotating shaft 25. A rack 23 corresponding to the gear 24 is provided on the top of the control slider 19, and the rack 23 is meshed with the gear 24; starting the motor 26 causes the rotating shaft 25 to rotate, thereby rotating the gear 24, thereby causing the rack 23 to move horizontally, thereby controlling the control slider 19 to move along the cross bar 22.

[0023] The working principle of the utility model is that when the easily oxidizable material is discharged after vacuum drying, the receiving port 12 is connected to the discharge port of the vacuum dryer by a pipeline, the storage tank 17 is placed on the lifting seat 31, the butt joint 27 is aligned with the discharge port 16, and the liquid pump and the oil tank are externally connected at the oil delivery port 32, and the liquid pump is started to pump hydraulic oil into the lifting box 29, so that the lifting plate 30 and the lifting seat 31 rise, thereby pushing the storage tank 17 against the discharge port 16, and the butt joint 27 is inserted into the discharge port 16, and then the solenoid valve in the discharge port 16 is opened, and the motor 26 is started to rotate the shaft 25, so that the gear 24 rotates, so that the rack 23 moves horizontally, so that The control slider 19 is controlled to move along the cross bar 22, and the closing plate 21 moves accordingly and separates from the receiving port 12. The material in the vacuum dryer enters the discharge tank 11 through the receiving port 12, and then falls into the storage tank 17 through the discharge port 16 and the docking pipe 27. When the storage tank 17 is full, the solenoid valve in the discharge port 16 is closed, and the liquid pump is started to extract the hydraulic oil in the lifting box 29. The lifting plate 30 and the lifting seat 31 move downward under the action of the spring, and the storage tank 17 moves downward accordingly, thereby separating the docking pipe 27 from the discharge port 16. Then, the docking pipe 27 is blocked with a rubber plug, the full storage tank 17 is taken away, and then a new storage tank 17 is replaced to continue discharging.
