Description
Technical Field
[0001] This utility model relates to the technical field of spray deodorization equipment, and in particular to a spray deodorization equipment. Background Technology
[0002] Spray deodorization equipment is used to remove odorous waste gas generated in industrial production. The equipment consists of a spray tower, an inlet for external waste gas, an outlet for an external fan, a packing layer, nozzles, spray pipes, connecting pipe assemblies, a self-priming pump, a mixing tank, a discharge pipe, and valves. When using the equipment, the worker opens the second cover (connected to the first cover by a hinge), pours the deodorizing agent and water into the mixing tank, mixes them according to the specified ratio, and then starts the self-priming pump. This allows the deodorizing liquid to enter the spray pipes through the first and second connecting pipes, and then be sprayed out from the nozzles. Industrial waste gas enters the spray tower through the inlet, rises, and undergoes a chemical reaction as it passes through the packing layer (using stepped ring packing). The deodorizing liquid sprayed from the nozzles then mixes with the waste gas after passing through the packing layer to remove odors. Finally, the deodorized waste gas is discharged through the outlet of the external fan, and the discharge pipe valve is opened to drain the deodorizing liquid from the bottom of the spray tower.
[0003] In their daily work, the inventors discovered that when using spray deodorization equipment, the deodorizing agent and water are usually mixed in a mixing tank using a stirrer. However, since ordinary stirrers are driven by a motor in one direction, the agitation effect of the stirrer on the mixture decreases as the mixing process continues, which may affect the mixing efficiency. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that in actual use, when deodorizing agents and water are mixed in a mixing tank, a stirrer is usually required for stirring. However, since ordinary stirrers are driven by a motor in one direction, the oscillation effect of the stirrer on the mixed liquid is reduced as stirring and mixing proceeds, which may affect the stirring and mixing efficiency. Therefore, a spray deodorization device is proposed.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a spray deodorization device, comprising a spray tower, wherein an inlet for external waste gas and an outlet pipe are fixedly connected to the arc surface of the spray tower, a valve is installed on the arc surface of the outlet pipe, an outlet for an external fan is fixedly connected to the top of the spray tower, a packing layer and a spray pipe are fixedly connected to the inner wall of the spray tower, a nozzle is fixedly connected to the lower end of the spray pipe, a second connecting pipe is fixedly connected to one end of the spray pipe, and a self-priming pump is installed at the lower end of the second connecting pipe. A first connecting pipe is fixedly connected to the inlet end, and a mixing tank is fixedly connected to the other end of the first connecting pipe. A first cover is fixedly connected to the top of the mixing tank. A second cover is provided on one side of the first cover and is rotatably connected by a hinge. A stirring assembly is provided on the inner wall of the mixing tank. The stirring assembly includes a stirrer and a rotating rod disposed on the inner wall of the mixing tank. An auxiliary mixing blade is fixedly connected to one side of the rotating rod. The stirrer and the auxiliary mixing blade are distributed alternately. A drive mechanism for driving the rotating rod and the stirrer to rotate is provided at the upper end of the first cover.
[0006] The effect achieved by the above components is as follows: by setting up a stirring assembly, when water and deodorant need to be mixed, water and deodorant are poured into a mixing tank, and then the driving mechanism causes the stirrer and rotating rod to rotate. The rotating rod and the stirrer stir in opposite directions, causing the auxiliary mixing blades to rotate, thereby achieving the effect of mixing water and deodorant as much as possible.
[0007] Preferably, the drive mechanism includes a sleeve rotatably connected to a first cover via a first bearing, a first bevel gear fixedly connected to the arcuate surface of the sleeve, and the sleeve and the rotating rod being fixedly connected.
[0008] The effect achieved by the above components is that the rotation of the first bevel gear causes the sleeve to rotate, which in turn causes the rotating rod to rotate.
[0009] Preferably, a second bevel gear is fixedly connected to the arc surface of the stirrer, and a third bevel gear meshes between the first bevel gear and the second bevel gear.
[0010] The effect achieved by the above components is as follows: the rotation of the third bevel gear causes the rotation of the second and first bevel gears, which in turn causes the stirrer to rotate, the sleeve to rotate, and the rotating rod to rotate, so that the stirring direction of the rotating rod and the stirrer is opposite.
[0011] Preferably, a mounting bracket is fixedly connected to the upper end of the first cover, and a motor is mounted on the right end of the mounting bracket.
[0012] The effect achieved by the above components is as follows: the motor on the mounting bracket is started, and the motor is connected to the third bevel gear through the reducer and coupling, so that the third bevel gear rotates.
[0013] Preferably, the motor controls the rotation of the third bevel gear, and a second bearing is provided between the sleeve and the agitator.
[0014] The effect achieved by the above components is to improve the relative rotational stability of the sleeve and the agitator by setting a second bearing.
[0015] Preferably, the outer ring of the second bearing is fixedly connected to the sleeve, and the inner ring of the second bearing is fixed to the agitator.
[0016] The effect achieved by the above components is that, by setting a second bearing, the auxiliary sleeve rotates on the agitator.
[0017] Preferably, a cleaning component is provided on one side of the rotating rod, the cleaning component including a scraper slidably connected to the inner wall of the rotating rod.
[0018] The effect achieved by the above components is that the rotating rod rotates, causing the scraper to rotate, thus cleaning the inner wall of the mixing tank.
[0019] Preferably, a spring is fixedly connected to the right end of the scraper, and the other end of the spring is fixed to the rotating rod.
[0020] The effect achieved by the above components is as follows: by setting a spring, the scraper contacts the inner wall of the mixing tank, the spring is compressed, and its reverse force pushes the scraper to fully contact the inner wall of the mixing tank.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting up a stirring assembly, when water and deodorant need to be mixed, water and deodorant are poured into a mixing tank. Then, through a drive mechanism, the stirrer and rotating rod rotate. The rotating rod and the stirrer stir in opposite directions, causing the auxiliary mixing blades to rotate, thereby maximizing the mixing effect of water and deodorant. This solves the problem that mixing deodorant and water in a mixing tank usually requires a stirrer, but ordinary stirrers are driven by a motor in one direction, and as mixing progresses, the agitation effect of the stirrer on the mixture decreases, which may affect the mixing efficiency.

[0029] Reference Figure 3 and Figure 4As shown, in this embodiment: the stirring assembly 2 includes a stirrer 21 and a rotating rod 22 disposed on the inner wall of the mixing tank 8. An auxiliary mixing blade 23 is fixedly connected to one side of the rotating rod 22. The stirrer 21 and the auxiliary mixing blade 23 are staggered. The upper end of the first cover 14 is provided with a driving mechanism 24 for driving the rotating rod 22 and the stirrer 21 to rotate. By setting the stirring assembly 2, when water and deodorant need to be mixed, water and deodorant are poured into the mixing tank 8, and then the driving mechanism 24 causes the stirrer 21 and the rotating rod 22 to rotate. The rotating rod 22 and the stirrer 21 rotate in opposite directions, causing the auxiliary mixing blade 23 to rotate, thereby maximizing the mixing of water and deodorant. The drive mechanism 24 includes a sleeve 246 rotatably connected to the first cover 14 via a first bearing. A first bevel gear 245 is fixedly connected to the arc surface of the sleeve 246. The sleeve 246 and the rotating rod 22 are fixedly connected. Rotation of the first bevel gear 245 causes rotation of the sleeve 246, which in turn causes rotation of the rotating rod 22. A second bevel gear 244 is fixedly connected to the arc surface of the stirrer 21. A third bevel gear 243 meshes between the first bevel gear 245 and the second bevel gear 244. Rotation of the third bevel gear 243 causes the second bevel gear 244 and the first bevel gear 245 to rotate, which in turn causes the stirrer 21 to rotate, the sleeve 246 to rotate, and the rotating rod 22 to rotate. Thus, the rotating rod 22 and the stirrer 21 stir in opposite directions. A mounting bracket 241 is fixedly connected to the upper end of the first cover 14. A motor 242 is mounted on the right end of the mounting bracket 241. Starting the motor 242 on the mounting bracket 241 activates the motor. The reducer and coupling are connected to the third bevel gear 243, causing the third bevel gear 243 to rotate. The motor 242 controls the rotation of the third bevel gear 243. A second bearing 247 is provided between the sleeve 246 and the agitator 21. By providing the second bearing 247, the relative rotational stability between the sleeve 246 and the agitator 21 is improved. The outer ring of the second bearing 247 is fixedly connected to the sleeve 246, and the inner ring of the second bearing 247 is fixed to the agitator 21. By providing the second bearing 247, the sleeve 246 is assisted to rotate on the agitator 21.

The cleaning assembly 3 includes a scraper 31 that is slidably connected to the inner wall of the rotating rod 22. When the rotating rod 22 rotates, the scraper 31 rotates, so that the scraper 31 cleans the inner wall of the mixing tank 8. A spring 32 is fixedly connected to the right end of the scraper 31. The other end of the spring 32 is fixed to the rotating rod 22. By setting the spring 32, the scraper 31 contacts the inner wall of the mixing tank 8. The spring 32 is compressed, and its reverse force pushes the scraper 31 to fully contact the inner wall of the mixing tank 8.
[0031] Working principle:
[0032] When using the spray deodorization equipment, the worker opens the second cover 16, which is connected to the first cover 14 via hinge 15, and pours the deodorizing agent and water into the mixing tank 8 for mixing. Then, the self-priming pump 6 is started, allowing the deodorizing liquid to enter the spray pipe 12 through the first connecting pipe 7 and the second connecting pipe 5, and then sprayed out from the nozzle 13. Industrial waste gas enters the spray tower 1 through the air inlet 4, rises, and undergoes a chemical reaction after passing through the packing layer 11 (stepped ring packing is used). Then, the deodorizing liquid sprayed from the nozzle 13 comes into contact with and mixes with the waste gas after passing through the packing layer 11 to remove odors. Then, the deodorized waste gas is discharged from the air outlet of the external fan. The valve 10 of the discharge pipe 9 is opened to discharge the deodorizing liquid at the bottom of the spray tower 1. When it is necessary to mix water and deodorizing agent, water and deodorizing agent are poured into the mixing tank 8, and then the motor 242 on the mounting bracket 241 is started. 2. The reducer and coupling are connected to the third bevel gear 243, causing the third bevel gear 243 to rotate, which in turn causes the second bevel gear 244 and the first bevel gear 245 to rotate, which in turn causes the agitator 21 to rotate, the sleeve 246 to rotate, and the rotating rod 22 to rotate. Thus, the rotating rod 22 and the agitator 21 stir in opposite directions, causing the auxiliary mixing blade 23 to rotate, thereby achieving the effect of mixing water and deodorant as much as possible. By setting the second bearing 247, the relative rotational stability of the sleeve 246 and the agitator 21 is improved. The rotation of the rotating rod 22 causes the scraper 31 to rotate, which cleans the inner wall of the mixing tank 8. By setting the spring 32, the scraper 31 contacts the inner wall of the mixing tank 8. The spring 32 is compressed, and its reverse force pushes the scraper 31 to fully contact the inner wall of the mixing tank 8. The rotating rod 22 is removed by removing the bolt 26 on the mounting block 25.
