[0038] Combined with Figures 1 to 3 , the embodiment of the present invention provides an absorption tower for spray-type organic waste gas treatment

[0039] Specifically, the absorption tower for spray-type organic waste gas treatment includes

[0040] Tower body 1

[0041] The stuffing box 2 has a receiving cavity 23 for receiving stuffing, which is arranged inside the tower body 1. The stuffing box 2 includes a first half box 21 and a second half box 22 pivotally connected to the tower body 1. When the first half box 21 and the second half box 22 are pivoted to the combined state, the first half box 21 and the second half box 22 form the receiving cavity 23 of the stuffing box 2. When the first half box 21 and the second half box 22 are pivoted to the open state, the receiving cavity 23 forms a blanking opening for discharging materials.

[0042] The driving mechanism 3 is arranged on the outer wall of the tower body 1 and is connected to the first half box 21 and the second half box 22 so that the first half box 21 and the second half box 22 can be switched between the combined state and the open state.

[0043] In this embodiment, first, the tower body 1 is a common structure of a spray absorption tower in the prior art, and it has a space inside. The specific structure will not be elaborated here. Secondly, the driving mechanism 3 arranged outside the tower body 1 can be an electric driving mechanism 3 or a manual driving mechanism 3, as long as it can drive the first half box 21 and the second half box 22 to switch between the combined state and the open state, and no specific limitation is made here. Moreover, the bottom surface of the receiving cavity 23 of the stuffing box 2 has several leakage holes, so that the organic waste gas can enter the lower part of the stuffing box 2 through the leakage holes.

[0044] In this solution, by setting the driving mechanism 3 to drive the first half box 21 and the second half box 22 to pivot, the first half box 21 and the second half box 22 can be switched between the combined state and the open state. Therefore, when replacing or cleaning the stuffing, the driving mechanism 3 on the outer wall of the tower body 1 can be operated to switch the first half box 21 and the second half box 22 to the open state, and the blanking opening of the receiving cavity 23 is opened, and the stuffing can fall to the bottom inside the tower body 1, which is convenient for workers to clean. When it is necessary to load the stuffing, only by operating the driving mechanism 3 on the outer wall of the tower body 1, the first half box 21 and the second half box 22 can be switched to the combined state to re-form the receiving cavity 23.

[0045] In an embodiment, the first half box 21 has a first pivot shaft 211. One end of the first pivot shaft 211 passes through the side wall of the tower body 1 and extends to the outside of the tower body 1 and is pivotally connected to the tower body 1, and the other end is pivotally connected to the tower body 1.

[0046] The second half box 22 has a second pivot shaft 221. One end of the second pivot shaft 221 passes through the side wall of the tower body 1 and extends to the outside of the tower body 1 and is pivotally connected to the tower body 1, and the other end is pivotally connected to the tower body 1.

[0047] In this embodiment, the first pivot shaft 211 and the second pivot shaft 221 can be pivotally connected to the side wall of the tower body 1 through bearings. At the same time, considering the use environment, corresponding mechanical seal structures can be adopted to protect the bearings and prevent the leakage of organic waste gas.

[0048] Further, the driving mechanism 3 includes a first driving component 31, and the first driving component 31 includes:

[0049] A rotating wheel 311 sleeved on the first pivot shaft 211 to enable the first pivot shaft 211 to rotate synchronously with the rotating wheel 311. The rotating wheel 311 further has an annular groove extending along the axial direction of the rotating wheel 311;

[0050] A flexible rope 312, one end of which is fixed to the rotating wheel 311 and can be wound around the annular groove on the rotating wheel 311 as the rotating wheel 311 rotates;

[0051] At least one first gear block 313 fixedly arranged on the outer wall of the tower body 1 and located below the rotating wheel 311. The first gear block 313 has a first gear bayonet 3131;

[0052] An opening degree control member 314 connected to the other end of the flexible rope 312. The opening degree control member 314 is configured to be able to abut against the first gear bayonet 3131 of the first gear block 313, so that the first gear block 313 restricts the upward movement of the opening degree control member 314.

[0053] In this embodiment, the flexible rope 312 can be made of a steel wire rope, and the rotating wheel 311 is driven to rotate by pulling the steel wire rope, and then the first pivot shaft 211 is driven to rotate, so that the first half-frame 21 is switched between the combined state and the opened state. The design of the first gear block 313 and the opening degree control member 314 is such that after the user pulls the steel wire rope, the opening degree control member 314 can be abutted against the first gear block 313 to restrict the rotational freedom of the rotating wheel 311, thereby achieving the purpose of fixing the position of the first half-frame 21, so that the first half-frame 21 maintains the combined state or the opened state.

[0054] In a further embodiment, the first gear bayonet 3131 forms an arc-shaped opening. The upper end of the opening degree control member 314 has a tapered portion 3141. The diameter of the small end of the tapered portion 3141 is smaller than the inner diameter of the arc-shaped opening, and the diameter of the large end of the tapered portion 3141 is larger than the inner diameter of the arc-shaped opening.

[0055] Specifically, the arc-shaped opening is formed by cutting a notch 3132 from a circular opening and penetrating the side wall of the first gear block 313, and the small end of the tapered portion 3141 of the opening degree control member 314 cannot pass through the notch 3132. When the opening degree control member 314 abuts in the arc-shaped opening of the first gear bayonet 3131, the small end of the tapered portion 3141 can be partially located above the arc-shaped opening, and the tapered portion 3141 of the opening degree control member 314 cannot move laterally out of the arc-shaped opening, ensuring the connection stability of the opening degree control member 314.

[0056] To make the opening degree of the first half frame 21 adjustable, the first driving assembly 31 further includes at least one second gear block 315, which is fixedly arranged on the outer wall of the tower body 1 and located between the rotating wheel 311 and the first gear block 313. The second gear block 315 has a second gear bayonet 3151, and the opening degree control member 314 is configured to be abutted against the second gear bayonet 3151 of the second gear block 315, so that the second gear block 315 restricts the upward movement of the opening degree control member 314. At least one second gear block 315 and the first gear block 313 are located on the same vertical line, and at least one second gear block 315 is arranged in sequence at a specific interval starting from the first gear block 313.

[0057] Specifically, the second gear bayonet 3151 also has an arc-shaped opening, and its structure is the same as that of the first gear block 313, which will not be elaborated here. In this embodiment, taking the setting of two second gear blocks 315 as an example, by setting two second gear blocks 315, and making the two second gear blocks 315 and the first gear block 313 on the same vertical line, and the two second gear blocks 315 are arranged in sequence at a specific interval starting from the first gear block 313, that is, the distance between the first second gear block 315 and the first gear block 313 is equal to the distance between the second gear block and the first gear block. With such a setting, the rotation of the rotating wheel 311 is divided into multiple gears, that is, each gear represents the rotation angle of the rotating wheel 311, that is, the opening degree of the first half frame 21, so that the opening degree of the first half frame 21 can be controlled to control the dropping speed of the packing.

[0058] In the present utility model, the driving mechanism 3 further includes a second driving assembly 32 having the same structure as the first driving assembly 31. The second driving assembly 32 is used to drive the second pivot shaft 221 to pivot, that is, the structure of the second driving assembly 32 is the same as that of the above-mentioned first driving assembly 31, but it is used to drive the second half frame 22 to switch between the combined state and the open state. The user can respectively control the first half frame 21 and the second half frame 22 through the first driving assembly 31 and the second driving assembly 32, so that there is more selection space for the opening degree of the feeding port of the packing box 2.

[0059] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the present utility model can easily think of various equivalent modifications or replacements, and these modifications or replacements should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
