Figure 2 Provided in the embodiments of this application Figure 1Enlarged view at A. The moisture-proof zinc oxide discharging bin 100 includes a storage bin 110, a drying bin 120 and a discharging device 130. In the embodiment of the present application, the storage bin 110 is used to store zinc oxide, the drying bin 120 is used to dry the zinc oxide, and the discharging device 130 is used to discharge the material in the storage bin 110 into a material truck or other storage equipment. Support legs 111 are provided at the bottom of the storage bin 110, and the support legs 111 lift the storage bin 110 to a suspended state to prevent it from contacting the ground and getting wet. The bottom wall of the storage bin 110 is inclined, and the lowest point of the bottom wall of the storage bin 110 is connected to the discharging device 130. The inclined setting can facilitate it to completely discharge the zinc oxide to the discharging device 130. The discharge device 130 includes a discharge pipe 131 connected to the bottom of the storage bin 110, and a discharge valve 131a is provided on the discharge pipe 131. The other end of the discharge pipe 131 is tilted downward and connected to a first connection port 132 and a second connection port 133 respectively through a three-way valve 131b. The three-way valve 131b is used to control the discharge pipe 131 to be connected to the first connection port 132 or the discharge pipe 131 to be connected to the second connection port 133. The first connection port 132 is used to communicate with a container for receiving zinc oxide, and the above container can be a material cart, a storage bag, etc. The above container and the first connection port 132 should have matching and corresponding ports to facilitate the connection between the two. The second connection port 133 is connected to a return pipe 134, and the return pipe 134 is used to return the zinc oxide in the discharge pipe 131 to the drying bin 120 for drying. A negative pressure pump 121 is provided at the top of the drying bin 120, and one end of the return pipe 134 away from the second connection port 133 is connected to the inlet end of the negative pressure pump 121, and the outlet end of the negative pressure pump 121 is connected to the drying bin 120 through a bag filter. During operation, the negative pressure pump 121 can form a negative pressure after being started, and further the zinc oxide in the discharge pipe 131 can be drawn into the drying bin 120 for drying. A drying device 140 is provided in the drying bin 120, and the drying device 140 is a prior art, and can be set with reference to the prior art, and will not be described in detail here. The bottom of the drying bin 120 shrinks to form a reducer 122, and the bottom end of the reducer 122 is connected to the storage bin 110, and a discharge valve 122a is provided on the reducer 122. When the drying is completed in the drying bin 120, the discharge valve 122a can be opened, and the zinc oxide that has been dried in the drying bin 120 can enter the storage cavity through the reducer 122. The discharge pipe 131 is connected to a gas supply device 150 , and the gas supply device 150 is used to introduce high-flow gas into the discharge pipe 131 to blow out the zinc oxide that is not completely discharged and deteriorated in the discharge pipe 131 .

[0021] In the embodiment of the present application, during the specific working process, when it is necessary to discharge the material, the gas supply device 150 is first turned on, and the gas supply device 150 passes gas into the discharge pipe 131 to blow out the deteriorated zinc oxide adhering to the discharge pipe 131 along the first connection port 132. Then, after closing the gas supply device 150, the zinc oxide receiving container is connected to the first connection port 132 and ensures the sealing state, and the unloading valve 131a is opened, and the zinc oxide in the storage bin 110 enters the receiving container through the discharge pipe 131 and the first connection end in turn. After the receiving container completes receiving the material, the three-way valve 131b is controlled to connect the discharge pipe 131 with the second connection port 133. At this time, the material in the storage tank will pass through the second connection port 133 of the discharge pipe 131 in turn under the action of the negative pressure pump 121, and the return pipe 134 enters the interior of the drying bin 120. The zinc oxide that has been dried in the drying bin 120 can enter the storage tank through the reducer 122 to complete storage.

[0022] As can be seen from the above, in the embodiment of the present application, by setting the air supply device 150 and the discharge pipe 131 to be connected, the high-pressure gas in the air supply device 150 can blow out the deteriorated zinc oxide remaining in the discharge pipe 131 and the first connection port 132, so as to prevent the deteriorated zinc oxide from entering the zinc oxide receiving container and reducing the product quality. The present application also provides a three-way valve 131b and the first connection port 132 and the second connection port 133 to more conveniently control the flow direction of the zinc oxide material. On the other hand, by cooperating with the drying bin 120 and the negative pressure pump 121, the present application can dry the zinc oxide stored in the storage bin after unloading, further preventing it from getting damp, and ensuring that the remaining zinc oxide can still remain dry after unloading.

[0023] In some embodiments, the gas supply device 150 includes a gas tank 151, a mounting plate 152 is fixed to the support leg 111, the gas tank 151 is fixed to the mounting plate 152, the gas tank 151 is connected to an exhaust pipe 153, the other end of the exhaust pipe 153 is connected to the discharge pipe 131, and an exhaust valve 153a is provided on the exhaust pipe 153. In the embodiment of the present application, through the above arrangement, during the working process, the exhaust valve 153a is opened, and the gas in the gas tank 151 will enter the discharge pipe 131 through the exhaust pipe 153 to complete the pneumatic flushing operation.

[0024] In some embodiments, the gas tank 151 is a nitrogen storage tank, and nitrogen is stored in the nitrogen storage tank. In the embodiment of the present application, by setting the gas tank 151 as a nitrogen storage tank and flushing nitrogen into the interior thereof, the gas introduced into the discharge pipe 131 by the gas supply device 150 will be nitrogen, and the nitrogen can squeeze out the air in the discharge pipe 131, reduce the oxygen content in the discharge pipe 131, and further effectively prevent the zinc oxide from being oxidized in the discharge pipe 131.

[0025] In some embodiments, an air pressure detection device 160 is included, and the detection end of the air pressure detection device 160 extends into the inner cavity of the discharge pipe 131. In the embodiment of the present application, the air pressure detection device 160 can be set to monitor the air pressure in the discharge hook in real time. During the unloading process, when the receiving container is connected to the first unloading end, the gas supply device 150 can continuously introduce gas into the discharge pipe 131. At this time, it can be judged by observing the reading of the air pressure detection device 160 whether the air tightness of the connection between the receiving container and the present device meets the standard.

[0026] In some embodiments, a feed pipe 112 is provided on the top of the storage bin 110, and a sealing valve is provided on the feed pipe 112. In the embodiment of the present application, zinc oxide can be stored in the storage bin through the feed pipe 112.

[0027] In some embodiments, a vibration motor is provided at the storage bin 110, and the vibration end of the vibration motor abuts against the outer wall of the storage bin 110. In the embodiment of the present application, through the above arrangement, the vibration motor can drive the storage bin 110 to vibrate, thereby facilitating the complete discharge of the zinc oxide material in the storage bin 110.

[0028] In some embodiments, the drying device 140 includes a heating jacket 141 connected to the bottom of the drying chamber 120, and a heating pipe 142 is spirally arranged on the outer wall of the heating jacket 141. The head and tail ends of the heating pipe 142 are respectively connected to a liquid inlet pipe 143 and a liquid outlet pipe 144. In the embodiment of the present application, a heat-conducting medium can be introduced into the heating pipe 142 through the liquid inlet pipe 143. After the heat-conducting medium enters the heating pipe 142, the heating pipe 142 is heated, thereby increasing the temperature in the drying chamber 120, so as to achieve the effect of rapid drying.
