[0031] Example 1

[0032] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a sewage deodorization device for a sewage treatment plant. The sewage deodorization device for a sewage treatment plant includes a main body component 100 and a stirring component 200.

[0037] Example 2

[0038] Reference Figure 2 to Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0039] Specifically, the filter element 201 includes a filter box 201a, an activated carbon net 201b, a second water inlet 201c, a second water outlet 201d, a first water pumping pipe 201e and a first metering pump 201f. The filter box 201a is located on one side of the mixing barrel 101, the activated carbon net 201b is movably connected to the filter box 201a, the second water inlet 201c is fixed to the top of the filter box 201a, the second water outlet 201d is fixed to one side of the filter box 201a, one end of the first water pumping pipe 201e is fixed to the end of the second water outlet 201d, and the other end is fixed to the end of the first water inlet 102, and the first metering pump 201f is arranged on the surface of the first water pumping pipe 201e.

[0040] The sewage will come into contact with the activated carbon net 201b through the second water inlet 201c, and the activated carbon net 201b will perform the first round of deodorization. At this time, all the sewage will be stored in the filter box 201a, and then the first metering pump 201f will be started to transfer the sewage to the mixing barrel 101 through the first pumping pipe 201e.

[0041] Specifically, the storage component 202 includes a storage box 202a, a bracket 202b, a third water outlet 202c, a second water pumping pipe 202d and a second metering pump 202e. The storage box 202a is located on one side of the mixing barrel 101, the bracket 202b is fixed to the bottom of the storage box 202a, the third water outlet 202c is fixed to the top of the storage box 202a, one end of the second water pumping pipe 202d is arranged at the end of the third water outlet 202c, and the other end is located at the top of the mixing barrel 101, and the second metering pump 202e is located on the surface of the second water pumping pipe 202d.

[0042] The second metering pump 202e can be started to transfer the deodorant solution stored in the storage box 202a and deliver it to the second rotating shaft 203e. When the second rotating shaft 203e rotates, the deodorant solution will contact the sewage and stir it.

[0043] Specifically, the rotating member 203 includes a motor 203a, a first rotating shaft 203b, a first gear 203c, a second gear 203d, a second rotating shaft 203e and a mixing plate 203f.

[0044] A notch is formed on the mixing plate 203f, and the mixing plate 203f is connected to the second rotating shaft 203e, and one end of the second water pumping pipe 202d is connected to the second rotating shaft 203e.

[0045] The starting motor 203a drives the first rotating shaft 203b to start rotating. When the first rotating shaft 203b rotates, it will also drive the first gear 203c to rotate together. Since the first gear 203c and the second gear 203d are meshed, the rotation of the first gear 203c will also drive the second gear 203d to rotate together. The rotation of the second gear 203d will drive the second rotating shaft 203e to rotate. The mixing plate 203f is fixed on the surface of the second rotating shaft 203e. When the second rotating shaft 203e rotates, it will rotate together and discharge the deodorant solution from the groove opened in the mixing plate 203f to mix with the sewage.

[0046] Specifically, the cleaning piece 204 includes a limit block 204a, a support column 204b, a baffle 204c, a limit pile 204d and a first spring 204e. The limit block 204a is located at the bottom of the second gear 203d, the support column 204b is fixed to the bottom of the limit block 204a, the baffle 204c is fixed to the bottom of the support column 204b, the limit pile 204d is located at the bottom of the baffle 204c, and the first spring 204e is arranged on the outside of the limit pile 204d.

[0047] After the sewage is discharged, the limit on the limit block 204a is released. At this time, the first spring 204e loses its force, and the return spring will lift the baffle 204c, and the baffle 204c will lift the support column 204b. A tooth-shaped groove is provided at the bottom of the second gear 203d, and the limit block 204a is tooth-shaped. When the support column 204b is lifted, the limit block 204a will be lifted and inserted into the groove for fitting.

[0048] Specifically, the cleaning component 204 also includes a first rotating column 204f, a first supporting plate 204g, a fixed column 204h, a cleaning plate 204i, a second rotating column 204l and a second supporting plate 204m. The first rotating column 204f is located at the bottom of the limiting pile 204d, the first supporting plate 204g is fixed to the surface of the first rotating column 204f, the fixed column 204h is fixed to the bottom of the first supporting plate 204g, the cleaning plate 204i is fixed to the bottom of the fixed column 204h, the second rotating column 204l is located on the surface of the second rotating shaft 203e, one end of the second supporting plate 204m is fixed to the surface of the second rotating column 204l, and the other end is fixed to one side of the cleaning plate 204i.

[0049] When the limit block 204a is fitted with the groove, the limit block 204a will rotate together with the second gear 203d, and the limit block 204a will drive the support column 204b to rotate, and the support column 204b will drive the baffle 204c to rotate, and the limit pile 204d will rotate together with the baffle 204c. At this time, the limit pile 204d will drive the first rotating column 204f to rotate. Since the first support plate 204g is fixed to the surface of the first rotating column 204f, it will also rotate together. The first support plate 204g drives the fixed column 204h to move. Since the cleaning plate 204i is fixed to the bottom of the fixed column 204h, it will also move along. The second rotating column 204l and the second support plate 204m play a stabilizing role. When the cleaning plate 204i rotates, it will also drive the second rotating column 204l and the second support plate 204m to rotate together, and clean the mixing barrel 101.

[0050] Example 3

[0051] Reference Figures 5 to 8 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0052] Specifically, the assembly 205 includes an adjusting frame 205a, a lower pressure column 205b, a swing block 205c, a fixed pile 205d and a support rod 205e. The adjusting frame 205a is located on the surface of the support column 204b, the lower pressure column 205b is arranged on the inner wall of the adjusting frame 205a, the swing block 205c is fixed to one side of the adjusting frame 205a, the fixed pile 205d is located on the side of the swing block 205c, the end of the support rod 205e is fixed to one side of the fixed pile 205d, and the swing block 205c is movably connected to the support rod 205e.

[0053] The adjusting frame 205a is located on the surface of the supporting column 204b, and one end of the pressing column 205b contacts the surface of the supporting column 204b, and the pressing column 205b is at the top of the baffle 204c. When the swing block 205c and the fixed end of the adjusting frame 205a move downward, the adjusting frame 205a will drive the pressing column 205b to move downward, and the pressing column 205b will press the baffle 204c downward. As the baffle 204c moves downward under the force, the limit block 204a and the supporting column 204b will move downward and release the merger with the groove.

[0054] Specifically, the assembly 205 further includes a connecting rod 205f and a handle 205g. The connecting rod 205f is fixed to one side of the swing block 205c, and the handle 205g is fixed to one end of the connecting rod 205f.

[0055] By lifting the handle 205g, the connecting rod 205f will be lifted. At this time, one end of the swing block 205c will be lifted and the other end will be pressed down. Since one side of the adjustment frame 205a is fixed to the swing block 205c, when one end of the swing block 205c is pressed down, the adjustment frame 205a will be pressed down together and drive the pressing column 205b to press down the baffle 204c. Since the baffle 204c is forced to move downward, the limit block 204a and the support column 204b will be forced to move downward, and the limit block 204a will also be separated from the groove and merged with the second gear 203d.

[0056] Specifically, the limiting member 207 includes a positioning block 207a, a second spring 207b, a moving block 207c, a limiting block 207d and a toggle plate 207e. The positioning block 207a is fixed to one side of the protective cover 206. One end of the second spring 207b is fixed to the inner wall of the positioning block 207a, and the other end is fixed to the inner wall of the moving block 207c. A slide groove M is provided on one side of the protective cover 206. The moving block 207c is slidably connected to the slide groove M. The limiting block 207d is fixed to the bottom of the moving block 207c, and the toggle plate 207e is fixed to the side of the moving block 207c.

[0057] The positioning block 207a is fixed to the side of the protective cover 206, one end of the second spring 207b is fixed in the positioning block 207a, and the other end is fixed in the moving block 207c. The moving block 207c can slide in the slide groove M. When the connecting rod 205f is lifted by the handle 205g, it will touch the inclined surface of the limiting block 207d. At this time, the limiting block 207d will move to one side, and the limiting block 207d will drive the moving block 207c to move to one side. The second spring 207b will be deformed by force, and the connecting rod After 205f is separated from the limiting block 207d, the reset elastic force of the second spring 207b will reset the moving block 207c. When the moving block 207c is reset, it will also drive the limiting block 207d to reset and limit the connecting rod 205f. When the limit is to be released, the toggle plate 207e is moved to one side to drive the moving block 207c to move to one side, and the limiting block 207d will also move with it, thereby releasing the limit on the connecting rod 205f and the connecting rod 205f can move downward.

[0058] Specifically, one end of the limiting block 207d is a bevel angle, and the bevel angle is forty-five degrees.

[0059] Forty-five degrees can more effectively contact the connecting rod 205f and push the limiting block 207d to one side.

[0060] When in use, the sewage is first transferred into the filter box 201a through the second water inlet 201c, and the sewage will come into contact with the activated carbon net 201b, and the activated carbon net 201b will perform the first round of deodorization. At this time, all the sewage will be stored in the filter box 201a, and then the first metering pump 201f is started to transfer the sewage to the mixing barrel 101 through the first pumping pipe 201e, according to the amount of sewage transferred by the first metering pump 201f.

[0061] The second metering pump 202e is started to deliver an equal proportion of deodorant solution, and the deodorant solution is delivered to the second rotating shaft 203e through the second metering pump 202e.

[0062] The starting motor 203a drives the first rotating shaft 203b to start rotating. When the first rotating shaft 203b rotates, it will also drive the first gear 203c to rotate together. Since the first gear 203c and the second gear 203d are meshed, the rotation of the first gear 203c will also drive the second gear 203d to rotate together. Then the rotation of the second gear 203d will drive the second rotating shaft 203e to rotate. Since the mixing plate 203f is fixed on the surface of the second rotating shaft 203e, when the second rotating shaft 203e rotates, the mixing plate 203f will rotate along with it and discharge the deodorant solution from the slot opened in the mixing plate 203f to mix with the sewage.

[0063] When the sewage is stirred, the sewage can be discharged from the first water outlet 103 into the sewage storage tank. Then, the toggle plate 207e is moved to one side to drive the moving block 207c to move to one side, and the limiting block 207d will also move with it, releasing the limit on the connecting rod 205f, and the connecting rod 205f can move downward.

[0064] Since the limit is released, the first spring 204e loses its force, and the return elastic force will lift the baffle 204c, the baffle 204c will lift the support column 204b, and the limit block 204a will be inserted into the groove for fitting.

[0065] After the limit block 204a fits with the groove, the limit block 204a will rotate together with the second gear 203d, the limit block 204a will drive the support column 204b to rotate, the support column 204b will drive the baffle 204c to rotate, the limit pile 204d will rotate together with the baffle 204c, and at this time the limit pile 204d will drive the first rotating column 204f to rotate.

[0066] Since the first support plate 204g is fixed on the surface of the first rotating column 204f, it will rotate together. The first support plate 204g drives the fixed column 204h to move. Since the cleaning plate 204i is fixed at the bottom of the fixed column 204h, it will also move and clean the mixing barrel 101.

[0067] After cleaning is completed, the connecting rod 205f will be lifted by the handle 205g. At this time, one end of the swing block 205c will be lifted and the other end will be pressed down. Since one side of the adjustment frame 205a is fixed to the swing block 205c, when one end of the swing block 205c is pressed down, the adjustment frame 205a will be pressed down together and drive the pressing column 205b to press down the baffle 204c. Since the baffle 204c is forced to move downward, the limit block 204a and the support column 204b will be forced to move downward, and then the limit block 204a will also be separated from the groove and merged with the second gear 203d.

[0068] When the connecting rod 205f is lifted up, it will touch the inclined surface of the limiting block 207d. At this time, the limiting block 207d will move to one side, and the limiting block 207d will drive the moving block 207c to move to one side. Then the second spring 207b will be deformed by the force. When the connecting rod 205f is separated from the limiting block 207d, the reset elastic force of the second spring 207b will reset the moving block 207c. When the moving block 207c is reset, it will also drive the limiting block 207d to reset together. At this time, the limiting block 207d will press the connecting rod 205f to limit it, and the sewage deodorization and cleaning work will be completed.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
