TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical equipment, in particular to a reaction kettle dehydration oxygen feeding equipment and feeding method. BACKGROUND

[0002] In modern production, the production scale is continuously improved, and for large-scale and intensive production mode, simple manual operation cannot meet the requirements. In order to enhance the feeding speed of the material and reduce the labor intensity during feeding, the feeding of solid powder is mostly carried out by mechanical equipment.

[0003] When the feeding product is in powder form, a large amount of dust will fly during feeding, which not only pollutes the environment, but also affects the health of the operators, especially in the chemical and pharmaceutical industries, and manual operation is required in the conditions of oxygen-free, inert gas protection or nuclear screen, etc. In these cases, people usually use operation boxes, also known as glove boxes, to create these special environments.

[0004] The existing glove box has low use intensity, poor air tightness, cannot carry out pressure reduction and gas replacement operation, and after negative pressure is extracted, the material powder adsorbed on the filter core after filtration cannot be backflushed, so the material dust filtered out will accumulate on the filter core, and long-term use will reduce the filtering effect of the filter core. SUMMARY

[0005] The present application solves the problems of the prior art, such as low use intensity, poor air tightness, inability to carry out pressure reduction and gas replacement operation, and inability to backflush the material powder adsorbed on the filter core after filtration, which reduces the filtering effect of the filter core after long-term use.

[0007] In the technical scheme, the glove box is made of metal material, and the gaps between adjacent plates are preferably sealed by welding to ensure the use strength and sealing performance. The glove box is further provided with a filtering device. Therefore, when air suction is needed, the external fan can be connected to the air outlet pipe of the filtering device, and then the fan is started to suck the air in the box body, thereby performing the negative pressure suction operation. The filtering device is further provided with a back flushing device. The air bag of the back flushing device is filled with compressed air. After the explosion-proof pulse valve is opened, the compressed air in the air bag enters the filtering device to blow on the filter element, thereby blowing the material dust adsorbed on the filter element back into the glove box, avoiding the accumulation of material dust on the filter element, and solving the problems of low use strength, poor air tightness, inability to perform the negative pressure suction operation, and inability to perform the back flushing operation on the material powder adsorbed on the filter element after filtration, and the reduction of the filtering effect of the filter element after long-term use.

Detailed Implementation

[0018] The following will refer to the appendices in the embodiments of the present invention. Figures 1-11 The technical solutions in the embodiments of the present invention will be described in detail below.

[0019] like Figures 1-3 As shown, a dehydration oxygen feeding device and feeding method for a reactor includes a glove box 1, a measuring component 2, a filtering device 3, a backflushing device 4, and a discharge component 5. The measuring component 2 is located above the glove box 1 and is connected to the top of the glove box 1. When in use, the measuring component 2 can measure the environment inside the glove box 1, thereby ensuring that the environment inside the glove box 1 meets the environmental requirements for unpacking and feeding. The filtering device 3 is located at the top of the glove box 1.

[0020] like Figures 1-3 As shown, when the air inside the box is extracted, the extracted air will be filtered by the filter device 3 before being discharged into the air, thereby preventing the material dust inside the box from being extracted along with the air. The back-blowing device 4 is located on one side of the filter device 3 and is connected to the filter device 3. The material dust in the extracted air will be filtered down by the filter device 3.

[0021] like Figures 1-3 As shown, the dust of the material will be adsorbed inside the filter device 3. At this time, the back-blowing device 4 will blow the compressed air into the filter device 3, thereby blowing the material dust adsorbed inside the filter device 3 back into the glove box 1, so as to avoid the material dust from accumulating in the filter device 3. The discharge component 5 is set at the lower end of the glove box 1 and connected to the discharge port of the glove box 1.

[0022] like Figures 1-3 As shown, after the material is unpacked, it will fall into the glove box 1. At this time, after the discharge assembly 5 is opened, the material in the glove box 1 can fall out of the glove box 1 by its own weight. The lower end of the glove box 1 is also equipped with a pneumatic vibrator 9.

[0023] As Figures 1-3 shown, the pneumatic vibrator 9 (the pneumatic vibrator 9 used is preferably of the turbine type, i.e. eccentric rotor type, which is a product in existence and thus will not be described in detail) is connected to the outer wall of the glove box 1 by mechanical fixation, so that during the process of unloading, if the material is adsorbed on the inner wall of the glove box 1 and cannot fall down, the pneumatic vibrator 9 can be started to vibrate the wall of the glove box 1, so as to shake the material down from the inner wall of the glove box 1.

[0024] As Figures 1-3 shown, the middle section of the glove box 1 is provided with an eyepiece 11 and a glove flange 12, the eyepiece 11 is located above the glove flange 12, and the glove box 1 is provided with a through hole at the eyepiece 11, the eyepiece 11 used is explosion-proof transparent glass, which is fixed on the glove box 1 by mechanical fixation (such as screws or metal pressing strips) and sealing rubber strips.

[0025] As Figures 1-3 shown, so that the material in the glove box 1 can be directly observed through the eyepiece 11 during use, and the glove flange 12 has two and is arranged on both sides of the eyepiece 11 (the glove flange 12 used is a product in existence, such as the glove flange 12 of Suzhou Hongcan Purification Technology Co., Ltd., and thus will not be described in detail), so that after the worker inserts both hands into the inside of the two glove flanges 12, the eyepiece 11 will be located at the middle position of the worker's body.

[0026] As Figures 1-3 shown, the glove box 1 is also provided with through holes at the positions of the two sets of glove flanges 12, and the two sets of glove flanges 12 are connected to the glove box 1 by mechanical fixation, so that after the worker inserts both hands into the inside of the two glove flanges 12, the worker can contact the material package through the glove flanges 12, so as to ensure that the environment in the glove box 1 can not be in contact with the external environment while the material package can be normally unpacked.

[0027] As Figures 1-3 shown, the glove box 1 is also provided with a grid 6, the grid 6 is located below the glove flange 12, and the grid 6 is connected to the inner wall of the glove box 1 by mechanical fixation (such as screws or bolts), after the material package is placed into the inside of the glove box 1, the material package can be placed on the grid 6, so as to facilitate the worker to unpack, and the materials of the grid 6 and the material box are preferably metal materials, to ensure the durability.

[0028] As Figures 1-3 shown, the glove box 1 is arranged on a fixed support 13, and the outer wall of the glove box 1 is connected to the fixed support 13 by welding, so as to avoid displacement of the glove box 1 during use, and one end of the glove box 1 is provided with a manhole cover 14, and the manhole cover 14 is hinged to the glove box 1, so that the manhole cover 14 can be rotated through the hinge point when needed.

[0029] As Figures 1-3 shown, the inner wall of the manhole cover 14 (i.e. the contact surface of the manhole cover 14 and the support of the glove box 1) is provided with a rubber pad, so that after the manhole cover 14 is closed, the gap between the manhole cover 14 and the glove box 1 can be sealed by the rubber pad, thereby avoiding leakage between the manhole cover 14 and the glove box 1 when negative pressure or nitrogen is applied. As Figures 1-3 shown, the glove box 1 is further provided with six threaded rods 8 on the end face at one end of the manhole cover 14, the threaded rods 8 are uniformly distributed with the axis of the manhole cover 14 as the center, and one end of the six threaded rods 8 is provided with a fixed seat 81, the fixed seat 81 is welded on the outer wall of the glove box 1, the end of the threaded rod 8 located in the fixed seat 81 is hinged on the fixed seat 81, and the other end of the six threaded rods 8 is provided with a handle 82.

[0030] As Figures 1-3 shown, the handle 82 is threadedly connected to the threaded rod 8, and the manhole cover 14 is provided with an arc-shaped groove at the positions corresponding to the six handles 82. After the manhole cover 14 is closed, the threaded rod 8 can be rotated clockwise, and after the outer wall of the arm contacts the manhole cover 14, the handle 82 is instantaneously rotated until the handle 82 is pressed on the manhole cover 14 at one end of the manhole cover 14. In this way, the manhole cover 14 at one end of the glove box 1 is pressed by the handle 82.

[0031] As Figures 1-3 shown, the other end of the glove box 1 is provided with a control box 15 (the control box 15 used is an existing product, such as the control box 15 of Suzhou Yunkong Explosion-proof Electrical Co., Ltd., so it is not described in detail), the control box 15 is vertically arranged and connected to the fixed support 13 by screws, and the control box 15 is electrically connected to the measuring assembly 2, so that after the measuring assembly 2 detects that the environment in the glove box 1 reaches the required standard, the indicator light on the control box 15 can display the result.

[0032] As Figures 1-3 shown, the upper part of the glove box 1 is further provided with a water inlet and an air inlet, the first manual valve 16 is arranged at the water inlet, the first manual valve 16 is connected to the glove box 1, and the first manual valve 16 is preferably a manual ball valve. After the feeding is completed, the first manual valve 16 can be opened, and then water can be injected into the glove box 1 through the water inlet, so as to clean the internal space of the glove box 1. The first ball valve 17 is arranged at the air inlet, and the first ball valve 17 used is a pneumatic valve.

[0033] As Figure 4As shown, one side of the first ball valve 17 is also provided with a pressure reducing filter 7, which is vertically arranged above the first ball valve 17 and connected with the first ball valve 17 through a pipeline. After the air in the glove box 1 is extracted, the first ball valve 17 can be opened, and then nitrogen is filled into the interior of the glove box 1 through the gas inlet. When the nitrogen is filled into the interior of the glove box 1, the unstable high-pressure inlet pressure can be adjusted to a constant working pressure through the pressure reducing filter 7, so as to ensure the stable inlet of the air.

[0034] As shown in the drawings, Figure 4 The measuring assembly 2 comprises a pressure transmitter 21, a humidity transmitter 22 and an oxygen concentration transmitter 23. The pressure transmitter 21 is vertically connected to the top end of the glove box 1 through a flange. The glove box 1 is provided with a pressure tapping hole at the position corresponding to the pressure transmitter 21. Therefore, when the negative pressure is extracted or the nitrogen is filled, the pressure in the glove box 1 can be detected through the pressure transmitter 21.

[0035] As shown in the drawings, Figure 4 The humidity transmitter 22 and the oxygen concentration transmitter 23 are both vertically arranged at the top end of the glove box 1 and are both connected to the glove box 1 through screw threads. The glove box 1 is provided with an opening at the position corresponding to the humidity transmitter 22 and the oxygen concentration transmitter 23, so as to facilitate the measurement of the internal environment of the glove box 1 by the humidity transmitter 22 and the oxygen concentration transmitter 23.

[0036] As shown in the drawings, Figures 5-7 The pressure transmitter 21, the humidity transmitter 22 and the oxygen concentration transmitter 23 are all electrically connected to the control box 15. Therefore, when the environment in the glove box 1 reaches the required standard, the corresponding indicator light on the control box 15 will be turned on, so as to remind the staff.

[0037] As shown in the drawings, Figures 5-7 The filtering device 3 comprises a main body 31, a filter core 32, an upper cover 33, an air outlet pipe 34, an air inlet pipe 35, a clamp 36, a second manual valve 37 and a second ball valve 38. The main body 31 is vertically arranged above the glove box 1. The glove box 1 is provided with an air outlet hole at the position corresponding to the main body 31. The lower end of the main body 31 is connected to the glove box 1 through the clamp 36 (the clamp 36 is a product in the prior art, and thus is not described in detail).

[0038] As shown in the drawings, Figures 5-7 The upper cover 33 is arranged at the upper end of the main body 31 and is connected to the main body 31 through the clamp 36. The filter core 32 is arranged in the interior of the main body 31 and is fixed through bolts. The air outlet pipe 34 and the air inlet pipe 35 are arranged at the two sides of the upper cover 33, respectively. The upper cover 33 is provided with an air outlet hole at the position corresponding to the air outlet pipe 34 and the air inlet pipe 35. The air outlet pipe 34 and the air inlet pipe 35 are both connected to the upper cover 33 through the clamp 36.

[0039] AsFigures 5-7 As shown, one end of the air inlet pipe 35 is connected to the top cover 33, and the other end of the air inlet pipe 35 is connected to the back-blowing device 4. Therefore, the high-pressure air blown out by the back-blowing device 4 can directly enter the interior of the main body 31 through the air inlet pipe 35. When it is necessary to extract the air from the glove box 1, the end of the air outlet pipe 34 can be connected to the external vortex fan, and then the vortex fan can be turned on to extract the air from the glove box 1.

[0040] like Figures 5-7 As shown, the second manual valve 37 (the third manual valve 43 used is a manual ball valve) is located at the end of the air outlet pipe 34, and the second ball valve 38 is located in the middle of the air outlet pipe 34 and connected to the air outlet pipe 34. The second ball valve 38 used is a pneumatic valve. The second ball valve 38 is equipped with a wireless communication module, so the second ball valve 38 can be remotely controlled when in use. When the air in the glove box 1 is extracted by a vortex fan or vortex air pump to create negative pressure.

[0041] like Figures 8-10 As shown, the material dust in the air inside the glove box 1 will be filtered and adsorbed onto the filter element 32. Then, the filtered air will be discharged through the air outlet pipe 34. Because the main body 31 and the upper cover 33 are connected together by the clamp 36, and the filter element 32 and the main body 31 are connected by bolts, the upper cover 33 and the main body 31 can be separated when needed, and the filter element 32 can be taken out from the inside of the main body 31 for replacement and cleaning.

[0042] like Figures 8-10 As shown, the backflush device 4 includes an air tank 41, a connecting bracket 42, a third manual valve 43, and an explosion-proof pulse valve 44. The air tank 41 (the air tank 41 used is an existing product, so it will not be described in detail) is located on one side of the main body 31. The connecting bracket 42 is located in the middle of the air tank 41 and the main body 31. One end of the connecting bracket 42 is connected to the outer wall of the air tank 41 by welding, and the other end of the connecting bracket 42 is connected to the main body 31 by bolts.

[0043] like Figures 8-10 As shown, the third manual valve 43 (the third manual valve 43 used is a manual ball valve) is located below the air tank 41 and connected to the air tank 41. After the third manual valve 43 is opened, compressed air can be filled into the air tank 41. The explosion-proof pulse valve 44 (the explosion-proof pulse valve 44 used is an existing product, so it will not be described in detail) is located above the air tank 41, and the air inlet and outlet of the explosion-proof pulse valve 44 are connected to the air tank 41 and the air inlet pipe 35 respectively by mechanical fixing.

[0044] like Figure 11As shown, therefore, when the filter element 32 needs to be back-flushed, the compressed air can be instantaneously released through the explosion-proof pulse valve 44 after receiving a signal, and then the compressed air can enter the inside of the main body 31 through the air inlet pipe 35, thereby back-flushing the filter element 32 inside the main body 31. One side of the air pocket 41 is also vertically provided with the explosion-proof pulse valve 44, which is connected with the air pocket 41. When needed, the unstable inlet air pressure can also be adjusted to a constant working pressure through the explosion-proof pulse valve 44, so as to ensure that the compressed air enters the inside of the air pocket 41 stably.

[0045] As shown in the figure, Figure 11 The discharge assembly 5 includes a third ball valve 51 and a rotary valve 52. The rotary valve 52 is arranged at the discharge port of the glove box 1. The rotary valve 52 is a pneumatic valve. The inlet of the rotary valve 52 is connected to the discharge port of the glove box 1 through a clamp 36. The third ball valve 51 is arranged below the rotary valve 52. The third ball valve 51 is also a pneumatic valve. The third ball valve 51 is connected to the rotary valve 52 in a mechanical fixed manner.

[0046] As shown in the figure, Figure 11 Therefore, after the rotary valve 52 is opened, the material can enter the inside of the third ball valve 51. After the third ball valve 51 is opened, the material can flow out of the third ball valve 51. The rotary valve 52 and the third ball valve 51 are both equipped with a wireless communication module. Therefore, during use, the rotary valve 52 and the third ball valve 51 can be remotely controlled and started or stopped through the wireless communication module.

[0047] As shown in the figure, ​ The feed pipe of the reaction kettle is connected to the discharge port of the third ball valve 51. Therefore, after the third ball valve 51 is opened, the material inside the glove box 1 can flow into the inside of the reaction kettle. After the material bag is opened, the material can be accumulated inside the glove box 1. Therefore, when the material flows out of the glove box 1, the flow rate of the material per unit time can be adjusted through the rotary valve 52. After the material feeding is completed, the rotary valve 52 and the third ball valve 51 can be closed, so as to avoid leakage.

[0048] The present application relates to a kind of reaction kettle dehydration oxygen feeding equipment and feeding method, comprising the following steps: Step one, equipment start-up: open equipment power, gas source and detect parameter setting whether correct; The control box 15 is provided with a display screen, and the control box 15 is connected with the measuring assembly 2. Therefore, after the power and the gas source are turned on, the control box 15 and the measuring assembly 2 are started. At this time, the gas pressure, humidity and other parameters in the glove box 1 can be observed through the display screen on the control box 15.

[0049] Step two, put the material: after the manhole cover 14 is opened, the material package can be put into the glove box 1 and placed on the grid 6, and then the manhole cover 14 is closed; After the end of the handle 82 is out of contact with the manhole cover 14, the threaded rod 8 can be rotated counterclockwise, and the six sets of threaded rods 8 and handles 82 are not in contact with the manhole cover 14, and the threaded rods 8 and handles 82 will not hinder the rotation of the manhole cover 14, so that the manhole cover 14 can be rotated and opened, and then the material package is put into the glove box 1, and after the material package is placed on the grid 6, the manhole cover 14 is closed. Rotate the threaded rod 8 clockwise, and when the outer wall of the handle 82 is in contact with the manhole cover 14, rotate the handle 82 clockwise until the end of the handle 82 is in contact with the manhole cover 14 and the handle 82 cannot be rotated, so as to ensure that the handle 82 presses the manhole cover 14.

[0050] Step three, replace the air: open the second manual valve 37 and the second ball valve 38, and exhaust the air in the glove box 1 through the air outlet pipe 34. In this process, the pressure transmitter 21 measures the pressure in the glove box 1. When the pressure in the glove box 1 reaches the standard, open the first ball valve 17 to fill nitrogen into the glove box 1. After opening the second manual valve 37 and the second ball valve 38, the inlet of the vortex fan (or vortex air pump) can be connected to the port of the air outlet pipe through the pipeline. Then open the vortex fan to exhaust the air in the glove box 1. When the air in the glove box 1 is exhausted, the exhausted air is first filtered by the filter element 32 before being discharged into the air. During the process of exhausting the air in the glove box 1, the pressure transmitter 21 (range set to ±1.5Kpa) continuously measures the gas pressure in the glove box 1. When the pressure in the glove box 1 reaches -1.5Kpa, the second ball valve 38 is closed and the first ball valve 17 is opened to fill nitrogen into the glove box 1. When the pressure in the glove box 1 reaches +1.5Kpa, the humidity transmitter 22 and the oxygen concentration transmitter 23 measure whether the humidity and oxygen concentration in the glove box 1 reach the index. If not, open the vortex fan and the second ball valve 38 again to exhaust the gas in the glove box 1 again until the pressure in the glove box 1 reaches -1.5Kpa again. Then close the second ball valve 38 and open the first ball valve 17 to fill nitrogen into the glove box 1. Again, the pressure in the glove box 1 is filled to +1.5Kpa. Replace the nitrogen in this way until the humidity transmitter 22 and the oxygen concentration transmitter 23 detect that the environment in the glove box 1 reaches the set index, and stop replacing.
