By starting the driving motor 203, the gear ring 202 is driven to rotate, and the rotation of the gear ring 202 drives the hollow transmission gear 204 to rotate. The hollow transmission gear 204 and the threaded rod 103 cooperate to drive the connecting support arm 101 to slide on the 30 storage mechanism 2, and drive the sealing cover plate 114 to slide in the inner storage layer 208, which is used to adjust the volume of the inner storage layer 208 according to the remaining amount of raw materials stored in the inner storage layer 208, while conveniently seeing the remaining amount of raw materials, avoiding external moisture or impurities from entering the inner storage layer 208 to affect the quality of the raw materials, and when discharging the raw materials in the inner storage layer 208, the driving motor 203 is started to drive the sealing cover plate 114 to be lowered in the inner storage layer 208 as the raw material liquid level drops, so as to avoid the generation of negative pressure in the inner storage layer 208 and make the raw material discharge smoother.

[0029] like Figures 1 to 10 As shown, a first transfer port 102 is fixedly installed on the top of the connecting support arm 101, and the first transfer port 102 is connected to the hard pipe at the bottom of the connecting support arm 101. A second transfer port 111 is fixedly installed on the sealing cover plate 114, and the second transfer port 111 and the first transfer port 102 are used to connect with the transfer pipe to store raw materials in the inner storage layer 208.

[0030] like Figures 1 to 10As shown, the inner wall of the pipeline at the top of the sealing cover plate 114 is provided with a plurality of positioning grooves 112, and a conical groove is provided in the center of the sealing cover plate 114. A conical sealing slider 104 is longitudinally slidably installed in the conical groove of the sealing cover plate 114, and a transmission pipeline is fixedly installed on the top of the conical sealing slider 104. A plurality of positioning sliders 113 are fixedly installed on the outer wall of the transmission pipeline at the top of the conical sealing slider 104. The positioning slider 113 slides in cooperation with the positioning groove 112, and a tension spring is fixedly installed between the positioning slider 113 and the top of the positioning groove 112. A plurality of flow grooves 106 are provided in the middle of the conical sealing slider 104, and the flow grooves 106 are connected with the pipeline in the middle of the conical sealing slider 104. When it is necessary to store raw materials in the inner storage layer 208, the sealing cover plate 114 is driven to rise by starting the driving motor 203, and the external transmission pipeline is respectively connected to the second transmission port 111 and the first transmission port 102, and the raw materials are stored in the inner storage layer 208. When the inner storage layer 208 is about to be full, the external transmission pump is turned off and the second transmission port 111 is closed so that the raw materials are no longer transmitted into the inner storage layer 208. At the same time, the pipeline connected to the first transmission port 102 and the second transmission port 111 is disconnected. Then the driving motor 203 continues to drive the sealing cover plate 114 to rise. The negative pressure generated in the inner storage layer 208 when the sealing cover plate 114 rises causes the adsorption conical sealing slider 104 to slide downward at the bottom of the sealing cover plate 114. At the same time, the raw materials remaining in the pipeline between the support arm 101 and the sealing cover plate 114 enter the inner storage layer 208 through the circulation groove 106 until the sealing cover plate 114 completely rises to the top of the inner storage layer 208, so that the pressure in the inner storage layer 208 is the same as that outside, so that the raw materials can flow out evenly when being extracted, and the splashing of raw materials can be prevented. At the same time, the pressure in the inner storage layer 208 can be adjusted as needed.

[0031] like Figures 1 to 10As shown, a pressure relief groove 107 is provided at the bottom center of the conical sealing slider 104, a pressure relief top plate 108 is longitudinally slidably installed in the pressure relief groove 107, a compression spring is fixedly installed between the pressure relief top plate 108 and the top of the pressure relief groove 107, a plurality of arc-shaped baffles 109 are fixedly installed on the pressure relief top plate 108, a hollow groove is provided at the bottom of the arc-shaped baffle 109, the top of the arc-shaped baffle 109 contacts and cooperates with the flow groove 106, and is used to cut off the connection between the flow groove 106 and the transmission pipeline at the top of the conical sealing slider 104, and the pressure relief groove 107 and the conical sealing slider 104 are connected. The pipeline at the top is connected, and a circular baffle 110 is fixedly installed on the top of the pressure relief chute 107 through a supporting short rod. The circular baffle 110 slides with the arc baffle 109. When the pressure in the inner storage layer 208 is too large, the raw material in the inner storage layer 208 pushes the pressure relief top plate 108 to slide upward in the pressure relief chute 107. At the same time, the top of the arc baffle 109 blocks the flow groove 106, so that excess raw material flows into the transmission pipeline on the top of the conical sealing slider 104 through the hollow groove at the bottom of the arc baffle 109, so that the pressure in the inner storage layer 208 is maintained in a safe range.

[0032] Working principle: When it is necessary to store the raw materials, firstly, connect the pipeline to the first transmission port 102 and the second transmission port 111, and transfer the raw materials to the inner storage layer 208 through the liquid pump. During this period, the driving motor 203 is started to drive the sealing cover plate 114 to rise slowly with the storage speed. When the inner storage layer 208 is about to be full, stop transferring the raw materials to the inner storage layer 208. At the same time, the sealing cover plate 114 continues to move upward to discharge the raw materials remaining in the pipeline between the connecting support arm 101 and the sealing cover plate 114 into the inner storage layer 208, so that the pressure in the inner storage layer 208 is the same as that outside, which is convenient for the subsequent control of the internal pressure of the inner storage layer 208.

[0033] During the storage process, the temperature inside the inner storage layer 208 is controlled by starting the temperature control sheet 209, and the temperature loss rate is slowed down by the heat insulation sealing ring 207 and the heat insulation material between the inner storage layer 208 and the outer protective layer 201.

[0034] When taking out the raw materials, by starting the driving motor 203 to drive the sealing cover plate 114 to slide in the inner storage layer 208, the speed of the raw materials flowing out of the discharge port 206 can be controlled so that it can flow out at a uniform speed, and the transmission can be stopped immediately after the taking out is completed to avoid waste of raw materials.
