Description

Technical Field

[0001] This utility model relates to a cooling tower for the preparation of nitrous oxide, belonging to the field of cooling tower technology. Background Technology

[0002] In the preparation of nitrous oxide, a cooling tower is used to cool the mixed gas produced by the decomposition of ammonium nitrate, so as to facilitate subsequent gas purification and separation processes.

[0003] However, during the preparation of nitrous oxide, the outlet at the top of the cooling tower cannot be completely closed, causing rainwater to seep into the water collection tank through the opening when the cooling tower is not in use. This results in the rainwater mixing with the solution when nitrous oxide needs to be cooled, thus causing a decrease in the purity of the solution.

[0004] Therefore, a new cooling tower for the preparation of nitrous oxide is provided to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cooling tower for the preparation of nitrous oxide in order to solve the above problems. The rainproof closed component can be closed on rainy days to reduce rainwater entering the cooling tower and make the concentration of nitrous oxide purer during cooling.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a cooling tower for the preparation of nitrous oxide, comprising a cooling tower body, supporting legs, a liquid inlet, a valve, a mounting bracket, and a fan, and further comprising a closed rainproof assembly and an auxiliary filter assembly. The supporting legs are fixedly installed on the lower part of the cooling tower body, the liquid inlet is opened on the side wall of the cooling tower body, the valve is fixedly installed on the lower part of the cooling tower body, the mounting bracket is fixedly installed inside the cooling tower body, the fan is rotatably connected to the upper part of the mounting bracket, the closed rainproof assembly is disposed on the upper part of the cooling tower body, and the auxiliary filter assembly is disposed outside the closed rainproof assembly.

[0007] Preferably, the cover plate has ventilation holes, and the rainproof closure assembly includes a mounting block fixedly installed on the side wall of the cooling tower body, a cylinder fixedly installed on the upper part of the mounting block, and a cover plate provided at the port of the cooling tower body.

[0008] Preferably, the rotating rod can drive the cover plate to open and close when it rotates, and an L-shaped fixing frame is fixedly installed on the side wall of the cooling tower body. The side wall of the L-shaped fixing frame has a slot, and a rotating rod is rotatably connected inside the slot. One end of the rotating rod is fixedly connected to the outer surface of the cover plate.

[0009] Preferably, the rotating shaft can drive the rotating rod to rotate when it rotates, and the rotating shaft is rotatably connected between the inner and outer walls of the L-shaped fixing frame, with one end of the rotating rod fixedly connected to the outer surface of the rotating shaft.

[0010] Preferably, the rack moves with the rod, gears are fixedly installed at both ends of the rotating shaft, a support block is fixedly installed on the side wall of the cooling tower, a rod slides on the upper part of the support block, and a rack is fixedly installed on the outer surface of the rod.

[0011] Preferably, the cylinder, after being turned on, drives the connecting rod to move. As the connecting rod moves, the rod body moves, which in turn moves the rack. As the rack moves, the gear rotates. When the gear rotates, the rotating shaft rotates, and as the rotating shaft rotates, the rotating rod rotates. When the rotating rod rotates, the cover plate opens and closes. This prevents rainwater and impurities from entering the cooling tower through the cooling tower opening when the device is not in use, thus avoiding material accumulation. The rack and gear mesh with each other, and the connecting rod is fixedly installed on the movable end of the cylinder. The outer surface of the connecting rod is fixedly connected to one end of the rod body.

[0012] Preferably, the ceramic filter plate can filter the gas escaping from the tower, thereby reducing environmental pollution during gas discharge. The auxiliary filter assembly includes an L-shaped connecting frame fixedly installed on the upper part of the rotating rod, and a circular groove is provided on the upper part of the cover plate, with a ceramic filter plate installed inside the circular groove.

[0013] Preferably, the motor is configured to drive the lead screw to rotate when turned on. As the lead screw rotates, it drives the ceramic filter plate to move upward. As the ceramic filter plate moves upward, the vent holes on the cover plate are exposed, allowing the gas inside the tower to escape. The lead screw is rotatably connected between the inner and outer walls of the L-shaped connecting frame. One end of the lead screw is fixedly connected to the back of the ceramic filter plate. A motor is fixedly installed on the upper part of the L-shaped connecting frame, and the output end of the motor is fixedly connected to one end of the lead screw.

[0014] The beneficial effects of this utility model are:

[0015] 1. The designed closed rainproof component, which closes and opens by rotation, prevents rainwater and debris from falling into the water collection tank through the tower opening when the device is not in use. This avoids the phenomenon that rainwater can seep into the water collection tank through the opening when the cooling tower is not in use, due to the air outlet at the top of the cooling tower not being able to close completely. This also solves the problem of the solution purity decreasing due to the mixing of rainwater and solution.

[0016] 2. The configured auxiliary filtration components are adjusted via a screw rotation mechanism to ensure the release of gas within the tower. Simultaneously, the installed ceramic filter plates effectively filter gases such as ammonium nitrate generated during the preparation process, making the cooling process more environmentally friendly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, a cooling tower for the preparation of nitrous oxide includes a cooling tower body 1, support legs 4, liquid inlet 5, valve 6, mounting bracket 7, and fan 8. It also includes a rainproof enclosure 2 and an auxiliary filter assembly 3. The support legs 4 are fixedly installed at the lower part of the cooling tower body 1. The liquid inlet 5 is opened on the side wall of the cooling tower body 1. The valve 6 is fixedly installed at the lower part of the cooling tower body 1. The mounting bracket 7 is fixedly installed inside the cooling tower body 1. The fan 8 is rotatably connected to the upper part of the mounting bracket 7. The rainproof enclosure 2 is located at the upper part of the cooling tower body 1. The auxiliary filter assembly 3 is located outside the rainproof enclosure 2. The rainproof enclosure 2 can be closed on rainy days to reduce rainwater entering the cooling tower body 1, thereby making the concentration of nitrous oxide purer during cooling.

[0025] like Figures 1-4As shown, the closed rainproof assembly 2 includes a mounting block 201 fixedly installed on the side wall of the cooling tower body 1. A cylinder 202 is fixedly installed on the upper part of the mounting block 201. A cover plate 203 is provided at the port of the cooling tower body 1. An L-shaped fixing bracket 204 is fixedly installed on the side wall of the cooling tower body 1. A slot is opened on the side wall of the L-shaped fixing bracket 204. A rotating rod 205 is rotatably connected inside the slot. One end of the rotating rod 205 is fixedly connected to the outer surface of the cover plate 203. A rotating shaft 206 is rotatably connected between the inner and outer walls of the L-shaped fixing bracket 204. One end of the rotating rod 205 is fixedly connected to the outer surface of the rotating shaft 206. Gears 207 are fixedly installed at both ends of the rotating shaft 206. A support block is fixedly installed on the side wall of the cooling tower body 1. A rod 208 slides on the upper part of the support block. A rack 209 is fixedly installed on the outer surface of the rod 208. The rack 209 meshes with the gear 207. A connecting rod 210 is fixedly installed at the movable end of 202. The outer surface of the connecting rod 210 is fixedly connected to one end of the rod body 208. When rainy weather is needed, the cylinder 202 is opened. As the cylinder 202 is opened, the connecting rod 210 can be moved. As the connecting rod 210 moves, the rod body 208 moves. As the rod body 208 moves, the rack 209 moves. As the rack 209 moves, the gear 207 rotates. When the gear 207 rotates, the rotating shaft 206 rotates. As the rotating shaft 206 rotates, the rotating rod 205 rotates. When the rotating rod 205 rotates, the cover plate 203 rotates and closes on the cooling tower body 1. This prevents rainwater and debris from falling into the water collection pool through the tower opening when the device is not in use. This avoids the problem that rainwater will seep into the water collection pool through the opening when the cooling tower is not in use because the air outlet at the top of the cooling tower cannot be completely closed.

[0026] like Figures 1-5 As shown, the auxiliary filter assembly 3 includes an L-shaped connecting frame 301 fixedly installed on the upper part of the rotating rod 205. A circular groove is opened on the upper part of the cover plate 203, and a ceramic filter plate 302 is arranged inside the circular groove. A lead screw 303 is rotatably connected between the inner and outer walls of the L-shaped connecting frame 301. One end of the lead screw 303 is fixedly connected to the back of the ceramic filter plate 302. A motor 304 is fixedly installed on the upper part of the L-shaped connecting frame 301. The output end of the motor 304 is fixedly connected to one end of the lead screw 303. When the cover plate 203 is closed at the port of the cooling tower body 1, it is necessary to prepare and process liquids such as nitrous oxide. At this time, the motor 304 is turned on to drive the lead screw 303 to rotate. As the lead screw 303 rotates, it can drive the ceramic filter plate 302 to move upward. As the ceramic filter plate 302 moves upward, the vent holes on the cover plate 203 are exposed, allowing the gas in the tower body to escape. At the same time, the ceramic filter plate 302 can filter the ammonium nitrate and other gases generated during the preparation, making the gases generated during the cooling preparation more environmentally friendly.
