AI Technical Summary
The existing slicing conveyor in the polymerization workshop is prone to slicing jams, which prevents it from opening properly, resulting in low production efficiency, high maintenance costs, and the inability to achieve continuous conveying.
A combination of electric slide gate valves and electric ball valves, along with a controller, enables continuous feeding. The slice conveying process is controlled by a level gauge and a pressure gauge to prevent jamming, and inflation and deflation valves are used to ensure continuous conveying.
This achieves continuous slice delivery, reduces failure rate and maintenance costs, and improves production efficiency.

[0014] Please refer to Figure 1 And Figure 2 The utility model discloses a kind of continuous slice conveying devices for polymerization workshop, for connecting at least one bunker 101, comprising: daily storage tank 102, first electric plug-in valve 103, first electric ball valve 104, metering tank 105, second electric plug-in valve 106, conveying tank 107, inflation valve 108, exhaust valve 109, electric valve 110 and controller 111;The controller is single-chip microcontroller purchased directly in market;
[0015] The daily storage tank 102 bottom is connected to the metering tank 105 by first electric plug-in valve 103 and first electric ball valve 104, and the metering tank 105 is provided with first liquid level meter 1051;
[0016] The metering tank 105 bottom is connected to the conveying tank 107 by second electric plug-in valve 106, and the conveying tank 107 is provided with inflation port 1071, exhaust port 1072 and pressure gauge 1073;Inflation valve 108 is connected to inflation port 1071;Exhaust valve 109 is connected to exhaust port 1072;Inflation valve 108 is used to be connected with nitrogen inlet pipeline, and exhaust valve 109 is used to be connected with nitrogen recovery pipeline;
[0017] The conveying tank 107 bottom is connected to the bunker 101 by electric valve 110;The controller is electrically connected first electric plug-in valve 103, first electric ball valve 104, first liquid level meter 1051, second electric plug-in valve 106, pressure gauge 1073, inflation valve 108, exhaust valve 109 and electric valve 110 respectively.
[0018] When the slice conveying starts, the daily storage tank 102 is ensured to store a sufficient amount of slices; then the controller opens the first electric ball valve 104, and then opens the first electric plug valve 103, so that the first electric ball valve 104 will not be blocked by the slices; the slices start to be discharged from the daily storage tank 102 to the metering tank 105, when the first liquid level meter 1051 at the top of the metering tank 105 sends a high material level alarm signal, the controller closes the first electric plug valve 103, and then closes the first electric ball valve 104, at this time, even if the slices are stuck on the first electric plug valve 103, there is no problem, because there is no slice between the first electric plug valve 103 and the first electric ball valve 104, then the first electric ball valve 104 is closed to ensure the sealing, and the slices will not be stuck on the first electric ball valve 104. Then the second electric plug valve 106 is opened, and the slices start to be fed into the conveying tank 107, when the pressure of the pressure gauge at the top of the conveying tank 107 approaches zero, it indicates that the slices in the metering tank 105 are completely discharged, the second electric plug valve 106 is closed, the air charging valve 108 is opened, and the electric valve 110 is opened, so that the slices are conveyed to the stock bin 101. When the pressure of the pressure gauge at the top of the conveying tank 107 is 600KPA, the slices in the conveying tank 107 are completely conveyed, the electric valve 110 is closed, the exhaust valve 109 is opened, and the conveying tank starts to exhaust. At the same time, the daily storage tank 102 discharges the slices to the metering tank 105, and the slices can be continuously conveyed in sequence.
