[0017] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "Reaction Kettle Feeding Protection System" is provided in conjunction with the accompanying drawings.
[0018] See Figure 1In this embodiment, the reactor feeding protection system includes a feeding trough 100 and a reactor 101 positioned vertically. A first valve 102 is provided between the feeding trough 100 and the reactor 101. The feeding trough 100 and the first valve 102 are connected by a first air inlet flange 103. The first air inlet flange 103 is connected to an inert gas conveying device 105 through a first pipe 104 to prevent air from entering the reactor 101 during feeding. The reactor 101 and the first valve 102 are connected by a second air inlet flange 106. The second air inlet flange 106 is connected to the inert gas conveying device 105 through a second pipe 107 to prevent gas from escaping from the reactor 101 during feeding. Before feeding, inert gas is introduced into the first inlet flange 103 and the second inlet flange 106 through the inert gas conveying device 105. Nitrogen is preferred as the inert gas. The inert gas removes the air between the materials in the feeding tank 100 and suppresses the reaction gas located at the top in the reactor 101. Then, the first valve 102 is opened to feed the materials. In this way, no air will be brought into the reactor 101 during the feeding process, which will affect the reaction and ensure product quality. At the same time, the gas in the reactor 101 will not escape into the feeding tank 100 through the first valve 102 during the feeding process, ensuring the safety of the production site.
[0019] See further Figure 2 In this embodiment, the space between the inner and outer walls of the first inlet flange 103 and the second inlet flange 106 is a hollow area. The first pipe 104 is connected to the hollow area of the first inlet flange 103, and the second pipe 107 is connected to the hollow area of the second inlet flange 106. Both the first inlet flange 103 and the second inlet flange 106 are provided with inlet holes 108. Inert gas enters the hollow areas of the first inlet flange 103 and the second inlet flange 106 through the first pipe 104 and the second pipe 107 respectively, and then enters the feeding tank 100 and the reaction vessel 101 through the inlet holes.
[0020] More specifically, in this embodiment, a plurality of air inlet holes 108 are uniformly and symmetrically arranged on the inner walls of the first air inlet flange 103 and the second air inlet flange 106. In this way, inert gas can uniformly enter the feeding tank 100 and the reactor 101 from the first air inlet flange 103 and the second air inlet flange 106 respectively, thereby improving the efficiency of air removal between materials in the feeding tank 100 and increasing the speed at which the reaction gas located at the top in the reactor 101 is suppressed. At the same time, the multiple uniformly distributed air inlet holes 108 can reduce the probability of the flanges being completely blocked.
[0021] See further Figure 1In this embodiment, a first flow meter 109 is installed on the first pipe 104 and a second flow meter 110 is installed on the second pipe 107. In this way, the first air inlet flange 103 and the second air inlet flange 106 can be determined as to whether they are blocked by checking whether the readings of the first flow meter 109 and the second flow meter 110 are normal.
[0022] More specifically, in this embodiment, the first flow meter 109 and the second flow meter 110 are both electrically connected to the central controller. An alarm 111 is also provided on the reactor 101. The alarm 111 is electrically connected to the central controller to warn of abnormal readings of the first flow meter 109 and / or the second flow meter, thereby prompting the operator to clean the first inlet flange 103 and the second inlet flange 106 in time.
[0023] Furthermore, in this embodiment, a second valve 112 electrically connected to the central controller is also provided on the first pipeline 104 to open and close the first pipeline 104; a third valve 113 electrically connected to the central controller is provided on the second pipeline 107 to open and close the second pipeline 107; the first valve 102 is also electrically connected to the central controller; by setting a program in the central controller, the first valve 102, the second valve 112, the third valve 113, the first flow meter 109, and the second flow meter 110 are associated. When the reading of the first flow meter 109 and / or the second flow meter 110 is abnormal during the feeding process, the first valve 102 will automatically close, and the alarm 111 will sound an alarm to prevent the escape of reaction gas and prevent air from entering the reactor, thus playing the role of automatic early warning and stopping the feeding. Moreover, after the feeding is completed, the second valve 112 and the third valve 113 will also automatically close shortly after the first valve 102 closes, avoiding the waste of inert gas.
