Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment device for adding chemicals for sewage treatment and a use method thereof. Background Art

[0002] Chemical wastewater treatment is a common physical and chemical treatment method, which is mainly used to remove suspended matter, colloidal substances and dissolved pollutants in wastewater. This method adds specific chemical agents to wastewater to make pollutants react chemically and form floccules that are easy to precipitate or filter, thereby achieving the purpose of purifying water quality.

[0003] In the prior art, most of the dosing sewage treatment devices are composed of a stirring mechanism and a dosing mechanism, which are independent of each other. The designated flocculant is added into the device through the dosing mechanism, and then stirred and mixed by the stirring mechanism to achieve sewage treatment. However, most of these devices only use simple stirring rods and other structures for stirring, and the dosing mechanism mainly puts the flocculant into the sewage from above, which makes it impossible for the flocculant to be quickly and fully mixed with the sewage, affecting the treatment efficiency.

[0004] Of course, with the development of technology, there are gradually emerging medicated sewage treatment devices with multiple mixed modes. However, if the traditional medicated sewage treatment device is directly replaced with a new device, although the treatment efficiency can be improved, the production cost will inevitably increase. At the same time, the direct elimination of old equipment that still has working capacity will also waste resources and is not conducive to the development of the green economy. Therefore, there is a need for a device that can be applied to the original medicated sewage treatment device to further improve its performance on the basis of its original function.

The control module 4 is used to drive the main shaft 2 to rotate and drive the sliding seat 32 to reciprocate along the axial direction of the main shaft 2 synchronously.

[0019] In the embodiment of the present invention, it is necessary to add that Figure 5 In the figure, the circle at the position corresponding to the dosing channel 21 represents a partial cross-section. The method for using the sewage treatment device comprises the following steps: Step 1: first remove the top cover of the original device, then fix the top plate 1 thereon with fasteners, and place the mixing module 3 as a whole inside the device; Step 2: transport the sewage treatment agent (flocculant) to the dosing channel 21 and start the control module 4; Step 3: The main shaft 2 is driven to rotate through the control module 4 and the sliding seat 32 is driven to slide along the axial direction of the main shaft 2 simultaneously. The main shaft 2 can drive the fixed seat 31 to rotate synchronously. The sliding seat 32 can drive the stirring rod 34 to rotate synchronously with the axis of the main shaft 2 as the rotation center through the hinge rod 341; at the same time, the sliding seat 32 can drive each stirring rod 34 to rotate around the hinge point of the hinge rod 341 through the connecting rod 33, so that each stirring rod 34 can swing periodically while rotating; in addition, in the process of the sliding seat 32 sliding up and down, the sewage treatment agent can be periodically injected into the sewage through the discharge hole 22 (directly injecting the agent from the middle of the equipment can make the sewage treatment agent quickly and fully contact with the sewage in the upper, middle and lower parts), so that the sewage can be treated efficiently.

[0020] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the control module 4 includes a connecting ring 42, a sliding ring 44 and a mounting plate 47, the connecting ring 42 and the sliding ring 44 are both slidably mounted on the main shaft 2, the mounting plate 47 is fixedly mounted on the top of the main shaft 2, and the top plate 1 is also provided with a driving unit 6 for driving the mounting plate 47 to rotate; the sliding ring 44 is arranged between the top plate 1 and the mounting plate 47, the connecting ring 42 is arranged between the top plate 1 and the fixing seat 31, and a plurality of reset springs 43 are also arranged between the connecting ring 42 and the fixing seat 31, When not affected by external force, the elastic force of the reset spring 43 will cause the connecting ring 42 to be located at the upper limit position; a transmission rod 41 is installed at the bottom of the connecting ring 42, and the end of the transmission rod 41 away from the connecting ring 42 passes through the fixed seat 31 and is connected to the sliding seat 32; a plurality of pressure rods 441 are arranged at the bottom of the sliding ring 44, and the bottom of the pressure rod 441 is always in contact with the upper surface of the connecting ring 42; an inclined adjustment seat 45 is also arranged below the mounting plate 47, and a top rod 46 in contact with the lower surface of the adjustment seat 45 is installed on the upper surface of the sliding ring 44.

[0021] In the embodiment of the present invention, the transmission rod 41 is passed through the fixed seat 31 along the axial direction of the main shaft 2, so that the sliding seat 32 and the connecting ring 42 can keep synchronous rotation with the fixed seat 31, and there is no need to set a sliding key structure, which can make the structure of the main shaft 2 simpler. When in use, it is only necessary to drive the mounting plate 47 to rotate through the driving unit 6, and the mounting plate 47 can drive the main shaft 2 and the adjustment seat 45 to rotate synchronously. Through the cooperation between the adjustment seat 45 and the push rod 46, and the elastic force provided by the reset spring 43, the sliding ring 44 will reciprocate up and down (the sliding ring 44 does not rotate synchronously with the main shaft 2). The sliding ring 44 can drive the connecting ring 42 to move synchronously through the pressure rod 441, and the connecting ring 42 can drive the sliding seat 32 to move up and down synchronously along the axial direction of the main shaft 2 through the transmission rod 41, thereby driving each stirring rod 34 to swing synchronously.

[0022] like Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the adjustment seat 45 is an annular structure, one side of which is hinged to the lower surface of the mounting plate 47, and a return torsion spring is provided at the hinge between the adjustment seat 45 and the mounting plate 47, which is used to make the adjustment seat 45 always be subjected to an upward flipping force to ensure that the adjustment seat 45 will not flip downward due to gravity. The mounting plate 47 is also provided with an adjustment unit 5 for adjusting the inclination of the adjustment seat 45.

[0023] In the embodiment of the present invention, the inclination of the mounting plate 47 is adjusted by the adjusting unit 5, so as to adjust the reciprocating motion stroke of the sliding ring 44, and finally after being transmitted to the sliding seat 32, the swing amplitude of the stirring rod 34 can be adjusted.

[0024] like Figure 4 As shown, as a preferred embodiment of the present invention, the adjustment unit 5 includes a telescopic member 51 installed on the mounting plate 47, a pressing block 52 is installed at the telescopic end of the telescopic member 51, and the pressing block 52 abuts against the upper end surface of the non-hinged side of the adjustment seat 45.

[0025] In the embodiment of the present invention, the telescopic member 51 can be an electric telescopic rod or a pneumatic telescopic rod, etc. When in use, it is only necessary to control the telescopic member 51 to extend and retract, and the telescopic member 51 can drive the pressing block 52 to move up and down synchronously. Due to the effect of the reset torsion spring, the upper end surface of the adjustment seat 45 can always abut against the pressing block 52, and the inclination of the adjustment seat 45 can be adjusted by adjusting the position of the pressing block 52.

[0026] like Figure 3 and Figure 4As shown in the figure, as a preferred embodiment of the present invention, the driving unit 6 includes a driving motor 61 installed on the top plate 1, the output end of the driving motor 61 is connected to a driving gear 62, a transmission gear 63 is installed on the mounting plate 47, and the driving gear 62 is meshed with the transmission gear 63. When in use, it is only necessary to start the driving motor 61, and the driving motor 61 can drive the driving gear 62 to rotate synchronously. Through the cooperation of the driving gear 62 and the transmission gear 63, the mounting plate 47 can be driven to rotate, and then the main shaft 2 can be driven to rotate synchronously.

[0027] like Figure 6 As shown in the figure, as a preferred embodiment of the present invention, the dimension of the sliding seat 32 along the axial direction of the main shaft 2 is larger than the dimension of the drug discharge hole 22 along the radial direction of the main shaft 2, so that the sliding seat 32 can always cover the drug discharge hole 22 during the movement within a certain range. This can prevent sewage from flowing back from the drug discharge hole 22 into the drug feeding channel 21 when no drug is added.

[0028] Working principle: When in use, first remove the top cover of the original equipment, then fix the top plate 1 (the top plate 1 can be customized according to the specific size of the equipment) on it through fasteners, and place the mixing module 3 as a whole inside the equipment, thereby completing the modification of the traditional equipment. Then the sewage treatment agent (flocculant) is transported to the dosing channel 21, and the drive motor 61 is started. The drive motor 61 can drive the drive gear 62 to rotate synchronously. Through the cooperation of the drive gear 62 and the transmission gear 63, the mounting plate 47 can be driven to rotate, and the mounting plate 47 can drive the main shaft 2 and the adjustment seat 45 to rotate synchronously. The main shaft 2 can drive the fixed seat 31 to rotate synchronously, and the sliding seat 32 can drive the stirring rod 34 to rotate synchronously with the axis of the main shaft 2 as the rotation center through the hinge rod 341. At the same time, through the cooperation of the adjustment seat 45 and the top rod 46, and the elastic force provided by the reset spring 43, the sliding ring 44 will reciprocate up and down (the sliding ring 44 does not rotate synchronously with the main shaft 2). The sliding ring 44 can drive the connecting ring 42 to move synchronously through the pressure rod 441, and the connecting ring 42 can drive the sliding seat 32 to move up and down synchronously along the axial direction of the main shaft 2 through the transmission rod 41. In the process of the sliding seat 32 sliding up and down, the sewage treatment agent can be periodically put into the sewage through the discharge hole 22. At the same time, the sliding seat 32 can drive each stirring rod 34 to rotate around the hinge point of the hinge rod 341 through the connecting rod 33, so that each stirring rod 34 is periodically swung while rotating, so that the sewage treatment agent quickly contacts the sewage in the upper, middle and lower parts, and realizes efficient treatment of the sewage.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
