Description

Technical Field

[0001] The invention relates to the technical field of chemical production, and in particular to a detachable sealing structure. Background Art

[0002] In the chemical production process, sometimes it is necessary to react liquid (liquid phase) into a final state of solid (solid phase). The liquid part can be transported through a pipeline, but the solid (solid phase) formed after the liquid (liquid phase) reaction cannot be transported through a pipeline and requires additional operations to remove and transfer.

[0003] This not only increases the production process, but also affects the continuity of production, increases production costs, and reduces production efficiency.

[0004] Moreover, the reaction tank used for the reaction is not convenient to flip over due to the connection relationship, which makes it difficult to remove the solid (solid phase) after the reaction from the reaction tank. If the bottom of the reaction tank is set to a structure that can be opened and closed, it is easy to cause poor liquid penetration and leakage due to insufficient sealing.

[0005] In addition, due to the differences in liquid (liquid phase) raw materials and the differences in the reaction process, the properties of the solid (solid phase) obtained in the end are also different. Some solids are easy to stick to the side walls of the reaction tank, while some solids expand in volume after the reaction, and the solid material and the side walls of the reaction tank squeeze each other, resulting in increased friction. Therefore, even if the bottom of the reaction tank is set to be open, the solid (solid phase) in the reaction tank may not fall smoothly, so it is very troublesome to take out the solid after the reaction. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a detachable sealing structure to solve the sealing problem in the process of liquid reacting to solid and the problem of how to quickly remove the solid after the reaction is completed in the prior art.

[0007] Based on the above purpose, the present invention provides a detachable sealing structure, including a steel trough connected to a rotating device A and a support plate fixedly connected to another rotating device B, wherein the rotating device A is located above the rotating device B, and the sealing structure further includes:

[0008] A guide rail is located above the support plate, and the guide rail is also fixedly connected to the rotary device B. A pressing mechanism is provided on both sides of the steel trough, which is used to press down the steel trough after contacting the guide rail;

[0009] A movable plate movably connected to the support plate is provided with a circle of rubber pads with the same shape as the bottom notch of the steel trough. The steel trough is set to be transparent up and down, the outer edge range of the rubber pads is larger than the bottom notch of the steel trough, and the inner edge range of the rubber pads is smaller than the bottom notch of the steel trough.

[0010] Furthermore, the movable plate is slidably connected to the upper end surface of the support plate, and a telescopic column is fixedly connected to the movable plate. A telescopic groove is provided in the support plate, and the telescopic column is slidably connected in the telescopic groove.

[0011] Furthermore, a telescopic spring is provided in the telescopic slot, and two ends of the telescopic spring are respectively connected to the telescopic column and the inner end of the telescopic slot.

[0012] Furthermore, the movable plate is provided with movable plate strips, and the movable plate is also provided with movable plate grooves, and the movable plate strips are slidably connected in the movable plate grooves.

[0013] Furthermore, an air channel is also provided in the telescopic column, and two ends of the air channel are respectively connected to the movable plate slot and the telescopic spring.

[0014] Furthermore, a strip spring is provided in the movable plate slot, and two ends of the strip spring are respectively connected to the bottom end of the movable strip and the bottom of the movable plate slot.

[0015] Furthermore, groove ears are fixedly connected to both sides of the steel groove, and the pressing mechanism is fixedly connected to the groove ears.

[0016] Furthermore, the downward pressure mechanism includes a fixed part, a movable connecting rod, a wheel axle and a downward pressure spring, the fixed part is fixedly connected to the groove ear, the movable connecting rod is slidably connected to the fixed part, the wheel axle is fixedly connected to the upper end of the movable connecting rod, and the wheel axle is also rotatably connected to a roller, the downward pressure spring is sleeved on the movable connecting rod, and the upper and lower ends of the downward pressure spring are respectively connected to the wheel axle and the fixed part.

[0017] Furthermore, the steel groove is rectangular, circular, trapezoidal or elliptical, and an O-ring groove is also provided on the bottom end surface of the steel groove.

[0018] Furthermore, a plurality of single grooves are arranged in the steel groove, and adjacent single grooves are separated by partitions, and the partitions are fixedly connected in the steel groove.

[0019] Beneficial effects of the present invention: 1. A steel tank that is transparent from top to bottom is provided as a reaction container, and a support plate that can cooperate with the steel tank is provided. The support plate is movably connected with a movable plate, and the bottom opening of the steel tank can be blocked during the reaction, which provides a prerequisite for the continuous production of high-temperature, violent, small-molecular-weight liquid-to-solid phase reactions. The solid after the reaction is completed can be directly taken out from the bottom opening of the steel tank, which is simple and convenient.

[0020] 2. By connecting the steel trough and the support plate to two rotating devices that can rotate synchronously, the steel trough and the movable plate on the support plate can be combined during the reaction, and a rubber pad with the same shape as the bottom notch of the steel trough is set on the movable plate, and an O-ring groove is also set on the bottom end surface of the steel trough. This ensures that the bottom of the steel trough can maintain sufficient sealing during the reaction to ensure the normal reaction.

[0021] 3. Set the movable plate to be movable. When the steel trough is separated from the support plate after the reaction is completed, the steel trough is pressed on the movable plate, so the steel trough can move the movable plate for a short distance before separating from the movable plate. During this process, the movable plate strips on the movable plate will be affected by the negative pressure in the telescopic groove and then shrink into the movable plate groove, so that negative pressure is generated in the steel trough. Then, after the steel trough is separated from the movable plate, air will quickly enter the steel trough, impacting the solids in the steel trough from the bottom, making the solids loose and easy to fall off.

[0022] 4. Set up a downward pressure mechanism. After the steel trough contacts the support plate, the roller in the downward pressure mechanism enters the guide rail. The roller rolls in the guide rail and begins to press down under the influence of the guide rail. The downward pressure is applied to the steel trough through the downward pressure spring, so that the steel trough is only pressed on the rubber pad on the movable plate to ensure sealing.

[0034] A first aspect of the present invention, as Figure 1 , Figure 2 and Figure 3 As shown, in order to facilitate the easy removal of the solid (solid phase) formed by the liquid (liquid phase) after the reaction from the reaction tank after completion, a steel tank 101 which is transparent from top to bottom is specially designed as the reaction tank, and a plurality of single tanks 103 are arranged in the steel tank 101, and adjacent single tanks 103 are separated by partitions 102, and the partitions 102 are fixedly connected in the steel tank 101. Among them, the steel tank 101 can be set to be rectangular, circular, trapezoidal or elliptical.

[0035] Preferably, the steel trough 101 is configured to be rectangular, and 1 to 50 single grooves 103 are provided in the steel trough 101, each having a length of 20 mm to 400 mm and a width of 20 to 150 mm.

[0036] Grooves 105 are fixedly connected to both sides of the steel groove 101, and the grooves 105 are used to connect the steel groove 101 to the rotating device A. The steel groove 101 can move in a small range on the rotating device A, but cannot be separated. In addition, a support plate 108 is fixedly connected to another rotating device B, and the rotating device A is located above the rotating device B.

[0037] A guide rail 107 is arranged above the support plate 108 , and the guide rail 107 is also fixedly connected to the rotary device B. A pressing mechanism 106 is arranged on both sides of the steel trough 101 for pressing down the steel trough 101 after contacting the guide rail 107 .

[0038] A steel trough 101 which is transparent from top to bottom is provided as a reaction container, and a support plate 108 which can cooperate with the steel trough 101 is provided, a movable plate 109 is movably connected to the support plate 108, and the steel trough 101 and the support plate 108 are respectively connected to two rotating devices which can rotate synchronously, so that the steel trough 101 and the movable plate 109 on the support plate 108 can be combined during the reaction.

[0039] Therefore, the bottom opening of the steel tank 101 can be blocked during the reaction, providing a prerequisite for the continuous production of high-temperature, violent, small-molecular-weight liquid-to-solid phase reactions. The solid after the reaction is completed can be directly taken out from the bottom opening of the steel tank 101, which is simple and convenient.

[0040] A movable plate 109 is movably connected to the support plate 108, and a circle of rubber pads 110 with the same shape as the bottom notch of the steel trough 101 is provided on the movable plate 109. The steel trough 101 is set to be transparent from top to bottom, and the outer edge range of the rubber pads 110 is larger than the bottom notch of the steel trough 101, and the inner edge range of the rubber pads 110 is smaller than the bottom notch of the steel trough 101.

[0041] Preferably, an O-ring groove 104 is further provided on the bottom end surface of the steel tank 101. The rubber pad 110 is used to ensure that the bottom of the steel tank 101 can maintain sufficient sealing during the reaction, thereby ensuring that the reaction proceeds normally.

[0042] A second aspect of the present invention, as Figure 1 , Figure 4 and Figure 5 As shown, in order to allow the solid to be easily and quickly taken out after the reaction is completed, to prevent the solid from sticking to the side wall of the reaction tank, or the solid expands in volume after the reaction, the solid material and the side wall of the reaction tank squeeze each other, resulting in increased friction and unable to detach. A movable plate 109 is provided to be slidably connected to the upper end surface of the support plate 108, and a telescopic column 115 is also fixedly connected to the movable plate 109, and a telescopic groove 117 is provided in the support plate 108, and the telescopic column 115 is slidably connected in the telescopic groove 117. In addition, a telescopic spring 118 is also provided in the telescopic groove 117, and the two ends of the telescopic spring 118 are respectively connected to the telescopic column 115 and the inner end of the telescopic groove 117.

[0043] A movable plate strip 111 is provided on the movable plate 109, and a movable plate slot 112 is also provided in the movable plate 109, and the movable plate strip 111 is slidably connected in the movable plate slot 112. A plate strip spring 113 is also provided in the movable plate slot 112, and the two ends of the plate strip spring 113 are respectively connected to the bottom end of the movable plate strip 111 and the bottom of the movable plate slot 112.

[0044] Particularly, an air passage 116 is further provided in the telescopic column 115 , and two ends of the air passage 116 are respectively communicated with the movable plate slot 112 and the telescopic spring 118 .

[0045] The movable plate 109 is set to be movable. When the steel tank 101 is separated from the support plate 108 after the reaction is completed, since the steel tank 101 is pressed on the movable plate 109, the steel tank 101 can move with the movable plate 109 for a short distance before being separated from the movable plate 109. During this process, the movable plate strips 111 on the movable plate 109 will be subjected to the negative pressure in the telescopic groove 117 and then contracted to the movable plate groove 112, so that negative pressure is generated in the steel tank 101. Then, after the steel tank 101 is separated from the movable plate 109, air will quickly enter the steel tank 101, impacting the solid in the steel tank 101 from the bottom, making the solid loose and easy to fall off.

[0046] A third aspect of the present invention is as follows Figure 1 , Figure 4 and Figure 6 As shown, in order to further improve the sealing performance in the steel tank 101 during the reaction, a pressing mechanism 106 is arranged on both sides of the steel tank 101, and the pressing mechanism 106 includes a fixing member 119, a movable connecting rod 120, a wheel shaft 121 and a pressing spring 122, wherein the fixing member 119 is fixedly connected to the groove ear 105, the movable connecting rod 120 is slidably connected to the fixing member 119, the wheel shaft 121 is fixedly connected to the upper end of the movable connecting rod 120, and a roller 123 is rotatably connected to the wheel shaft 121, and the pressing spring 122 is sleeved on the movable connecting rod 120, and the upper and lower ends of the pressing spring 122 are respectively connected to the wheel shaft 121 and the fixing member 119.

[0047] After the steel groove 101 contacts the support plate 108, the roller 123 in the pressing mechanism 106 enters the guide rail 107, and the roller 123 rolls in the guide rail 107 and starts to press down under the influence of the guide rail 107, and applies the downward force to the steel groove 101 through the pressing spring 122, so that the steel groove 101 is only pressed on the rubber pad 110 on the movable plate 109 to ensure the sealing. Specific embodiment:

[0049] The rotating device A and the rotating device B cooperate synchronously, and the steel trough 101 on the rotating device A is combined with the support plate 108 on the rotating device B within a certain period of time, and after the combination, they can rotate synchronously at the same speed within the period of time.

[0050] When the steel trough 101 is combined with the support plate 108, the roller 123 in the pressing mechanism 106 first enters the guide rail 107, and the roller 123 rolls in the guide rail 107 and begins to press down under the influence of the guide rail 107, and applies the downward pressure to the steel trough 101 through the pressing spring 122, so that the steel trough 101 is only pressed on the rubber pad 110 on the movable plate 109, thereby ensuring the sealing of the steel trough 101 during the reaction process.

[0051] Then, liquid is injected into the single tank 103 in the steel tank 101 and the reaction is completed. After the liquid (liquid phase) reacts and becomes solid (solid phase), the rotating device A and the rotating device B manipulate the steel tank 101 to separate from the support plate 108.

[0052] At this time, since the steel trough 101 is still pressed on the movable plate 109, the steel trough 101 can move the movable plate 109 for a short distance before separating from the movable plate 109. During this process, the movable plate strips 111 on the movable plate 109 will be subjected to the negative pressure in the telescopic grooves 117 and then contracted into the movable plate grooves 112, so that negative pressure is generated in the steel trough 101.

[0053] When the roller 123 in the last pressing mechanism 106 leaves the guide rail 107, the pressing spring 122 no longer applies pressure to the steel trough 101, so the steel trough 101 automatically bounces up, so that the steel trough 101 is separated from the movable plate 109.

[0054] The air will quickly enter the steel trough 101 and impact the solid in the steel trough 101 from the bottom, making the solid loose. Finally, under the action of its own gravity, the solid can automatically fall off from the steel trough 101.

[0055] In summary, the present invention sets a steel tank 101 which is transparent from top to bottom as a reaction vessel, and sets a support plate 108 which can cooperate with the steel tank 101. The support plate 108 is movably connected with a movable plate 109, which can block the bottom opening of the steel tank 101 during the reaction, providing a prerequisite for the continuous production of high-temperature, violent, small-molecular-weight liquid-to-solid phase reactions. The solid after the reaction is completed can be directly taken out from the bottom opening of the steel tank 101, which is simple and convenient. The steel tank 101 and the support plate 108 are respectively connected to two rotating devices that can rotate synchronously, so that the steel tank 101 and the movable plate 109 on the support plate 108 can be combined during the reaction, and a rubber pad 110 with the same shape as the bottom notch of the steel tank 101 is set on the movable plate 109, and an O-ring groove 104 is also provided on the bottom end surface of the steel tank 101. The bottom of the steel tank 101 can maintain sufficient sealing during the reaction to ensure that the reaction proceeds normally. The movable plate 109 is set to be movable. When the steel tank 101 is separated from the support plate 108 after the reaction is completed, since the steel tank 101 is pressed on the movable plate 109, the steel tank 101 can move with the movable plate 109 for a short distance before being separated from the movable plate 109. During this process, the movable plate strips 111 on the movable plate 109 will be subjected to the negative pressure in the telescopic groove 117 and then contracted to the movable plate groove 112, so that negative pressure is generated in the steel tank 101. Then, after the steel tank 101 is separated from the movable plate 109, air will quickly enter the steel tank 101, impacting the solid in the steel tank 101 from the bottom, making the solid loose and easy to fall off. A pressing mechanism 106 is provided. After the steel groove 101 contacts the support plate 108, the roller 123 in the pressing mechanism 106 enters the guide rail 107. The roller 123 rolls in the guide rail 107 and starts to press down under the influence of the guide rail 107. The pressing spring 122 applies the downward force to the steel groove 101, so that the steel groove 101 is only pressed on the rubber pad 110 on the movable plate 109 to ensure the sealing.
