Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a cleaning device for a visual observation window of a reaction vessel. Background Technology

[0002] Currently, reaction vessels are used in chemical production processes. Depending on the working state of the reaction vessel, the internal conditions are also different. For some chemical products being processed in the reaction vessel, it is necessary to observe the internal reaction at all times. Therefore, existing reaction vessels are generally equipped with transparent observation windows on the side of the reaction vessel, so that the staff can observe the internal reaction through the transparent observation windows.

[0003] When the reactor is in operation, the chemical products inside can easily adhere to the observation window, making it difficult for personnel to observe the situation inside the reactor. At the same time, the temperature and humidity inside the reactor are relatively high, while the temperature of the outer wall of the observation window is relatively low, causing water vapor to condense on the inner wall of the observation window and form fog. This phenomenon affects the transparency of the observation window, thereby affecting the observation of the situation inside the reactor. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1-5This is the first embodiment of the present invention, which provides a cleaning device for a visual observation window of a reaction vessel. The device includes a vessel body 1, with an inlet pipe and a outlet pipe connected to one side of the vessel body 1. A sealing cover 2 is provided on the top of the vessel body 1, and the sealing cover 2 is fixed to the vessel body 1 by bolts or other fixing methods. A stirring mechanism 4 is provided on the sealing cover 2. An observation window body 3 is provided on the inner wall of the vessel body 1, and a cleaning mechanism 5 is provided on the inner wall of the vessel body 1. A fixing plate 6 is fixedly connected to one side of the vessel body 1, and the top of the fixing plate 6 is respectively provided with… The demisting mechanism 8 and the dust removal mechanism 9 are included; the cleaning mechanism 5 includes a paddle 51 disposed on the inner wall of the vessel body 1, a fixed rod 52 is fixedly connected to the top of the paddle 51, a first bearing 53 is fixedly connected to the outside of the fixed rod 52, a positioning rod 54 is fixedly connected to the top of the fixed rod 52, and a brush roller 55 is fixedly connected to the outside of the positioning rod 54 by screws; the demisting mechanism 8 includes a first guide groove 81 opened on the inner wall of the vessel body 1, a fan 82 is disposed on the top of the fixed plate 6, and the air outlet of the fan 82 is connected to the inner wall of the first guide groove 81.

[0029] The cleaning mechanism 5 also includes a second guide groove 56 and a guide groove 57 respectively opened on the inner wall of the vessel body 1. The blade 51 is located in the second guide groove 56, and the first bearing 53 slides in the guide groove 57.

[0030] The cleaning mechanism 5 also includes a second bearing 58 disposed at the top of the positioning rod 54, the outer side of the second bearing 58 being slidably connected to the inner wall of the vessel body 1.

[0031] The defogging mechanism 8 also includes a filter box 83 connected to the air intake of the fan 82, and an air intake pipe 84 is connected to one side of the filter box 83.

[0032] A protective shell 7 is provided on the top of the fixing plate 6, and a through hole is provided on one side of the protective shell 7.

[0033] When the stirring mechanism 4 reciprocates to stir the material in the vessel 1, the liquid enters the second guide channel 56 and causes the blade 51 to move and rotate, thereby causing the fixed rod 52 to drive the first bearing 53 to move. The first bearing 53 moves through the guide channel 57 and simultaneously drives the positioning rod 54 and the brush roller 55 to move. The positioning rod 54 can move stably through the second bearing 58, and the brush roller 55 can clean the material adsorbed on the inner wall of the observation window body 3.

[0034] Then, the fan 82 and the dust removal mechanism 9 are started. The dust removal mechanism 9 sprays water to form a water curtain inside the filter box 83. The fan 82 draws outside air into the filter box 83 through the suction pipe. When the air passes through the water curtain, the water molecules in the water curtain collide and adsorb with the dust particles in the air, filtering out the dust and preventing it from entering the fan 82. Under the action of the fan 82, the air is transported to the first guide channel 81 and blown along the first guide channel 81 onto the observation window body 3, thereby removing the water vapor on the surface of the observation window body 3 and reducing the condensation of water vapor on the observation window, thus achieving the defogging effect.

[0035] Example 2:

[0036] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the stirring mechanism 4 includes a housing 41 disposed on the top of the sealing cover 2, a positive and negative motor 42 disposed on one side of the housing 41, a drive wheel 43 fixedly connected to the output end of the positive and negative motor 42, and a driven wheel 44 meshing with the outer side of the drive wheel 43.

[0038] Specifically, the stirring mechanism 4 also includes a connecting shaft 45 fixed to the inner ring of the driven wheel 44. The top of the connecting shaft 45 is rotatably connected to the top of the inner cavity of the housing 41 through a bearing seat, and the bottom end of the connecting shaft 45 passes through the bottom of the sealing cover 2 and is fixedly connected to the stirring blade 46.

[0039] Specifically, the stirring mechanism 4 also includes a connecting rod 47 fixed to the outside of the connecting shaft 45, and a scraper 48 is fixedly connected to the inner wall of the connecting rod 47 by screws.

[0040] The forward and reverse motor 42 on one side of the outer casing 41 is started to rotate, thereby driving the drive wheel 43 to rotate forward and reverse. When the drive wheel 43 rotates forward and reverse, it can drive the driven wheel 44 to drive the connecting shaft 45 to rotate forward and reverse, thereby causing the stirring blade 46 to reciprocate to stir the material inside the vessel 1, improving the stirring efficiency. The rotation of the stirring blade 46 will generate a specific liquid flow pattern in the vessel 1, forming a pressure difference, which will guide some liquid into the second guide channel 56. The liquid entering the second guide channel 56 impacts the blade 51. During this process, the connecting rod 47 drives the scraper 48 to rotate synchronously with the connecting shaft 45. The scraper 48 can prevent the material from adhering to the inner wall of the vessel 1.

[0041] Example 3:

[0042] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, the dust removal mechanism 9 includes a water tank 91 located on the top of the fixed plate 6, a filter box 83 whose bottom is fixedly connected to the top of the water tank 91, a water pump 92 located on the top of the filter box 83, the pumping end of the water pump 92 being connected to the top of the water tank 91 via a connecting pipe, and the draining end of the water pump 92 being connected to a diversion pipe 93 via a delivery pipe, with several nozzles 94 located on the outside of the diversion pipe 93.

[0044] Specifically, the dust removal mechanism 9 also includes a return hole 95 opened on the inner wall of the filter box 83 and the water tank 91, and a filter screen 96 is snapped onto the inner wall of the water tank 91.

[0045] The water pump 92 is started to draw water from the water tank 91 and deliver it to the diversion pipe 93. Finally, the water is sprayed out from several nozzles 94 to form a water curtain. The water in the filter box 83 flows back to the water tank 91 through the return hole 95, and is filtered by the filter screen 96 before being drawn out by the water pump 92 again, thereby achieving the purpose of circulating spraying.

[0046] When in use, the reciprocating liquid enters the second guide groove 56 and drives the paddle 51 to move and rotate the fixed rod 52. At this time, the first bearing 53 moves through the guide groove 57 and synchronously drives the positioning rod 54 and the brush roller 55 to move. The brush roller 55 cleans the material adsorbed on the inner wall of the observation window body 3.

[0047] Next, the blower 82 and the dust removal mechanism 9 are started. The dust removal mechanism 9 sprays water to form a water curtain inside the filter box 83. The blower 82 draws outside air into the filter box 83 through the air intake pipe 84. The air passes through the water curtain to achieve the purpose of filtration, preventing dust from entering the blower 82. The filtered air is delivered by the blower 82 to the first guide channel 81 and blown onto the observation window body 3, thereby achieving the defogging effect and making it easier for personnel to observe the situation inside the vessel.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
