Description

Technical Field

[0001] This utility model relates to the field of material drying technology, and more specifically, to a vibration dryer. Background Technology

[0002] Vibratory dryers are widely used in various industries for material drying due to their simple structure and high drying efficiency. During operation, vibratory dryers require the introduction of hot steam to dry the materials, and the equipment operates under negative pressure to accelerate drying. However, after drying is complete, the vibratory dryer needs to be depressurized. Manually opening the bottom valve to discharge the material after depressurization results in low efficiency. If the discharge valve remains slightly negatively pressurized when open, foreign objects can easily be drawn into the dryer. In the lithium battery industry, where strict control of metal foreign objects is crucial, manual depressurization and discharge pose a significant risk due to the potential introduction of foreign objects.

[0003] Therefore, how to provide a vibration dryer that prevents the introduction of foreign objects during the depressurization process has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] See Figure 1 This utility model discloses a vibratory dryer with intelligent pressure relief and material discharge function, which includes a PLC, a dryer body 1, a negative pressure system, a pressure calibration device, a pressure relief device and a material discharge device.

[0032] The dryer body 1 has an inner cavity for drying materials. A filter device is installed on the dryer body 1 and communicates with the inner cavity. The filter device includes a filter canister 6, which filters the gas flowing between the negative pressure device and the pressure relief device and the inner cavity, preventing foreign objects from entering the inner cavity and preventing the material in the inner cavity from overflowing into the environment. The backflushing device 5 includes a backflushing air pipe 4, which is connected to the filter canister 6. Compressed air introduced into the backflushing air pipe 4 backflushes the filter element in the filter canister 6 to clean the filter canister 6.

[0033] The vibratory dryer also includes a first pressure gauge 2 and a second pressure gauge 3 installed on the dryer body 1 for detecting the internal pressure. The first pressure gauge 2 is used to detect the air pressure in the internal cavity, and the second pressure gauge 3 is used to calibrate the air pressure in the internal cavity.

[0034] The negative pressure device is connected to the filter tank 6 and provides negative pressure to the inner cavity through the filter tank 6. Specifically, the negative pressure device includes a negative pressure pipe 10 and a negative pressure valve 9. The negative pressure valve 9 is installed on the negative pressure pipe 10, and the negative pressure pipe 10, the filter tank 6 and the inner cavity are connected in sequence.

[0035] The pressure relief device is connected to the filter canister 6, supplying air to the inner cavity for pressure relief through the filter canister 6. Specifically, the pressure relief device includes a drying air pipe 8 and a replenishing air valve 7, with the replenishing air valve 7 installed on the drying air pipe. The drying air pipe 8, the filter canister 6, and the inner cavity are connected in sequence. The drying air pipe 8 is connected to the negative pressure pipe 10 and is connected between the negative pressure valve 9 and the filter canister 6. Both the negative pressure valve and the replenishing air valve are electrically controlled valves.

[0036] A discharge device, installed on the dryer body, is used to discharge material from the inner cavity. The discharge device includes a discharge valve 11, a connecting rod 12, a cylinder 14, and a solenoid valve 13. The two ends of the connecting rod 12 are connected to the discharge valve 11 and the cylinder 14, respectively. The solenoid valve is electrically connected to the cylinder, and the cylinder 14 drives the discharge valve to open and close. The PLC is connected to the first pressure gauge, the second pressure gauge, and the alarm signal.

[0037] More specifically, the vibratory dryer includes a negative pressure system, a pressure calibration device, a pressure relief device, and a discharge device. The negative pressure system consists of a backflush pipe 4, a backflush device 5, a filter tank 6, a negative pressure valve 9, and a negative pressure pipe 10. When the vibratory dryer is drying materials, the negative pressure valve 9 is opened, and the negative pressure source evacuates the vibratory dryer through the negative pressure pipe 10. The filter tank 6 is used to intercept the materials inside the vibratory dryer. The backflush device 5 uses compressed air introduced into the backflush pipe 4 to backflush the filter element in the filter tank 6, backflushing the materials adsorbed on the filter element into the vibratory dryer. The pressure calibration device consists of two pressure gauges: the first pressure gauge 2 is used to monitor the pressure value inside the vibratory dryer. To ensure the accuracy of the first pressure gauge 2 and avoid pressure measurement errors due to its malfunction, the pressure values ​​of the first pressure gauge 2 and the second pressure gauge 3 are transmitted to the PLC before the vibratory dryer starts operating. When the pressure difference between the first pressure gauge 2 and the second pressure gauge 3 exceeds the set value, the system will issue an alarm, and the pressure relief and discharge device will stop working. It can only be used again after the first pressure gauge 2 and the second pressure gauge 3 have been calibrated and returned to normal. The pressure relief device consists of a gas supply valve 7 and a drying gas pipe 8. After the vibratory dryer finishes drying, the negative pressure valve 9 closes, the gas supply valve 7 opens, and the drying gas enters the vibratory dryer through the drying gas pipe 8, achieving a rapid pressure relief effect. When the pressure value inside the vibratory dryer reaches the set value (the vibratory dryer is under slight positive pressure), the gas supply valve 7 closes. The discharge device consists of a discharge valve 11, a connecting rod 12, a solenoid valve 13, and a cylinder 14. One end of the connecting rod 12 is connected to the discharge valve 11, and the other end is connected to the cylinder 14. After the pressure is released, the signal to close the air supply valve 7 is sent to the solenoid valve 13, and the cylinder 14 is activated to open the discharge valve 11. After the discharge is completed, the operation button on the control cabinet can control the cylinder 14 to close the discharge valve 11.

[0038] In summary, the vibratory dryer provided by this utility model, after the drying process is completed, closes the negative pressure valve 9 to stop vacuuming, and automatically opens the gas supply valve 7 to replenish the vibratory dryer with drying gas. When the pressure inside the vibratory dryer reaches the set value, the gas supply valve 7 closes to stop gas supply, and the discharge valve 11 is automatically opened by the cylinder 14 to discharge the material, thereby realizing intelligent discharge, improving the working efficiency of the vibratory dryer, and effectively preventing the introduction of foreign objects.
