Description

Technical Field

[0001] This utility model relates to the field of treatment device technology, specifically to a wastewater thallium removal treatment device. Background Technology

[0002] Wastewater generally refers to water that has been polluted to a certain extent, and if left untreated, it will cause environmental pollution. Currently, when treating thallium-containing wastewater, thallium removal agents are added to the wastewater. During the wastewater treatment process, stirring is usually used to mix the wastewater with the thallium removal agent to promote a better mixing effect.

[0003] For example, the wastewater treatment mixer disclosed in patent CN221894734U, although it uses a dosing device to add chemicals into a mixing tank through a chemical tank and a dispensing pipe, and a drive mechanism to drive a rotating shaft and stirring blades to stir the wastewater and chemicals, while the rotating shaft rotates simultaneously, it drives the dosing head to rotate through a transmission assembly, and the chemicals enter the wastewater sequentially through a connecting pipe, a dosing branch pipe, and a dosing nozzle, which facilitates uniform feeding, accelerates the dissolution of chemicals, and ensures thorough mixing; however, in actual use, because the height of the stirring blades in the mixing tank is relatively fixed, it is difficult to ensure that the wastewater and chemicals at different heights are mixed well, resulting in a mediocre mixing effect, and therefore needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater thallium removal treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wastewater thallium removal treatment device includes a base plate, a treatment cylinder on the base plate, a treatment chamber with an opening at the top inside the treatment cylinder, and a detachable top cover at the opening of the treatment chamber. The top cover includes two semi-circular plates that are spliced ​​together.

[0007] The base plate is provided with a support assembly and a stirring assembly. The support assembly includes a fixed frame and an extension plate that can be raised and lowered. The fixed frame is provided with a drive assembly, which is used to drive the extension plate to rise and fall.

[0008] The stirring assembly includes a rotating shaft mounted on an extension plate and rotatable, with multiple sets of stirring blades on the rotating shaft, which can extend into the processing chamber.

[0009] The stirring blades are also equipped with a removable cleaning component, which includes a scraper that can abut against the inner wall of the processing chamber.

[0010] Preferably, the end faces where the semicircular plates are joined are provided with positioning grooves and positioning blocks. The positioning blocks can be inserted into the corresponding positioning grooves. The sides of the semicircular plates are also provided with countersunk screws that extend into the positioning grooves. The countersunk screws are used to fix the positioning blocks.

[0011] Preferably, the driving component includes a movable groove disposed within a fixed frame, one end of an extension plate being movably disposed within the movable groove, and a rotatable rotating rod disposed within the movable groove. The rotating rod is threaded through the extension plate, and its rotation is used to drive the extension plate to rise and fall.

[0012] Preferably, the top of the mounting bracket is provided with a first motor for driving the rotating rod to rotate.

[0013] Preferably, the cleaning assembly includes a first frame detachably mounted on the stirring blade, a bolt fixedly connected to the first frame, a nut threaded onto one end of the bolt, a movable second frame mounted on the bolt, and a scraper located on one side of the second frame.

[0014] Preferably, a spring is fitted onto the bolt, and the spring is used to push the scraper against the inner wall of the processing chamber.

[0015] Preferably, the extension plate is provided with a second motor for driving the rotating shaft to rotate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the setting of a fixed frame, an extension plate, a stirring shaft and stirring blades, enables the stirring blades to rise and fall within the treatment chamber. Compared with the existing technology, when mixing thallium-containing wastewater and thallium removal agent, the stirring blades can rise and fall within the treatment cylinder through the raising and lowering of the extension plate, which can mix at different heights within the treatment chamber, resulting in a better mixing effect.

[0018] 2. This utility model, through the detachable design of the cleaning component, allows the cleaning component to be removed from the stirring blade when mixing thallium-containing wastewater and thallium removal agent. This eliminates the need for the cleaning component to be immersed in the thallium-containing wastewater, thus avoiding affecting its normal use. When the thallium-containing wastewater is discharged from the treatment chamber and the inner wall of the treatment chamber needs to be cleaned, the cleaning component can be installed on the stirring blade, allowing the cleaning component to clean the inner wall of the treatment chamber as the stirring blade rotates, for subsequent use.

[0030] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0031] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0032] Please see Figures 1-3 The wastewater thallium removal treatment device in this embodiment includes a base plate 100, a treatment cylinder 130 on the base plate 100, a treatment chamber 200 with an opening at the upper end inside the treatment cylinder 130, and a detachable upper cover at the opening of the treatment chamber 200. The upper cover includes two semi-circular plates 140 spliced ​​together.

[0033] The base plate 100 is provided with a support assembly and a stirring assembly. The support assembly includes a fixed frame 110 and an extension plate 120 that can be lifted and lowered thereon. The fixed frame 110 is provided with a drive assembly, which is used to drive the extension plate 120 to lift and lower.

[0034] The stirring assembly includes a rotating shaft 122 that is mounted on the extension plate 120 and is rotatable. The rotating shaft 122 is provided with multiple sets of stirring blades 400, which can extend into the processing chamber 200.

[0035] The stirring blade 400 is also equipped with a removable cleaning component, which includes a scraper 430 that can abut against the inner wall of the processing chamber 200.

[0036] In this embodiment, a feeding pipe 141 is provided on the semi-circular plate 140, and a discharge pipe 201 is provided at the bottom of the treatment chamber 200. A valve is provided on the discharge pipe 201. When treating thallium-containing wastewater, firstly, the valve on the discharge pipe 201 is closed, and the thallium-containing wastewater and thallium removal agent (such as cationic polymer, aluminum sulfate, ferric chloride) are added to the treatment chamber 200 through the corresponding feeding pipes 141. Then, the rotating shaft 122 drives the stirring blade 400 to rotate, and the thallium-containing wastewater and thallium removal agent are stirred to mix them. After they are mixed evenly, the valve in the discharge pipe 201 is opened to discharge the thallium-containing wastewater and thallium removal agent from the treatment chamber 200, so that they can enter the sedimentation tank for sedimentation treatment.

[0037] The bottom surface of the base plate 100 is provided with multiple support legs 101. The support legs 101 can support the base plate 100 and raise the discharge pipe 201 so that the external pipe can be connected to the discharge pipe 201 so that the mixed thallium-containing wastewater can be discharged.

[0038] In this embodiment, the fixed frame 110, extension plate 120, rotating shaft 122 and stirring blade 400 are arranged so that the stirring blade 400 can be raised and lowered within the treatment chamber 200. Compared with the existing method, in this embodiment, when mixing thallium-containing wastewater and thallium removal agent, the raising and lowering of the extension plate 120 can make the stirring blade 400 rise and fall within the treatment cylinder 130, which can mix different heights within the treatment chamber 200, resulting in a better mixing effect.

[0039] The detachable design of the cleaning component allows it to be removed from the stirring blade 400 during the mixing of thallium-containing wastewater and thallium removal agent, eliminating the need for the cleaning component to be immersed in the thallium-containing wastewater and thus ensuring its normal operation. When the thallium-containing wastewater is discharged from the treatment chamber 200 and the inner wall of the treatment chamber 200 needs to be cleaned, the cleaning component can be installed on the stirring blade 400, allowing it to rotate with the stirring blade 400 to clean the inner wall of the treatment chamber 200 for subsequent use.

[0040] Specifically, the scraper 430 can also rise and fall together with the stirring blade 400, thereby enabling the scraper 430 to clean different heights of the processing chamber 200, making the cleaning effect of the scraper 430 better.

[0041] The interlocking arrangement of the semicircular plates 140 allows the top cover to be removed from the top of the processing cylinder 130 when a cleaning component needs to be installed on the mixing blade 400. Then, the semicircular plates 140 are separated so that the mixing blade 400 can extend from the upper opening of the processing chamber 200. This facilitates the installation of the cleaning component on the mixing blade 400.

[0042] like Figures 1-3 As shown, in this embodiment, the end faces of the semicircular plates 140 that are spliced ​​together are provided with positioning grooves 300 and positioning blocks 301. The positioning blocks 301 can be inserted into the corresponding positioning grooves 300. The side of the semicircular plates 140 is also provided with countersunk screws 302 that extend into the positioning grooves 300. The countersunk screws 302 are used to fix the positioning blocks 301.

[0043] In this embodiment, when splicing the semicircular plates 140 together, the positioning block 301 of one semicircular plate 140 is aligned with the positioning groove 300 of the other semicircular plate 140 and inserted. Then, the positioning block 301 is fixed in the positioning groove 300 using countersunk screws 302. Thus, the two semicircular plates 140 are combined to form a top cover. The top cover can seal the upper opening of the processing chamber 200, minimizing the possibility of thallium-containing wastewater splashing out of the processing chamber 200 during stirring.

[0044] like Figure 3 As shown, a connecting part is formed on the side wall of the semicircular plate 140. The connecting part is connected to the outer side wall of the processing cylinder 130 by threads. A notch is provided in the middle of the semicircular plate 140 for the rotating shaft 122 to pass through, so that the semicircular plate 140 will not affect the rotation of the rotating shaft 122.

[0045] like Figures 1-2 As shown, in this embodiment, the driving component includes a movable groove 111 disposed in the fixed frame 110, one end of the extension plate 120 is movably disposed in the movable groove 111, and a rotatable rotating rod 112 is also disposed in the movable groove 111. The rotating rod 112 is threaded through the extension plate 120, and the rotation of the rotating rod 112 is used to drive the extension plate 120 to rise and fall.

[0046] In this embodiment, since the extension plate 120 is restricted by the moving groove 111 and the rotating rod 112 is threaded through the extension plate 120, when the rotating rod 112 rotates, the extension plate 120 will move along the axial direction of the rotating rod 112, causing the rotating shaft 122 and the stirring blade 400 located thereon to rise and fall within the processing chamber 200, mixing the thallium-containing wastewater and the thallium removal agent, or causing the stirring blade 400 to extend out of the processing chamber 200 so as to allow the cleaning components to be disassembled and assembled on the stirring blade 400;

[0047] Specifically, the top of the fixed frame 110 is provided with a first motor 113 for driving the rotating rod 112 to rotate;

[0048] The extension plate 120 is equipped with a second motor 121 for driving the rotating shaft 122 to rotate. The second motor 121 enables the rotating shaft 122 and the stirring blade 400 to rotate.

[0049] like Figures 4-5 As shown, in this embodiment, the cleaning component includes a first frame 410 detachably mounted on the stirring blade 400, a bolt 500 fixedly connected to the first frame 410, a nut 502 threadedly connected to one end of the bolt 500, a movable second frame 420 mounted on the bolt 500, and a scraper 430 mounted on one side of the second frame 420.

[0050] In this embodiment, as Figure 5 As shown, the first frame 410 is mounted on the stirring blade 400 on the same side by screws, that is, the first frame 410 is mounted vertically. When it is necessary to connect the two, the top cover can be removed from the upper opening of the processing chamber 200 and the stirring blade 400 can be extended out of the processing chamber 200. At this time, it is convenient to connect the stirring blade 400 and the first frame 410.

[0051] Specifically, a spring 501 is fitted on the bolt 500. The spring 501 is used to push the second frame 420 away from the stirring blade 400, so that the scraper 430 presses against the inner wall of the processing chamber 200, and can clean the inner wall of the processing chamber 200 when it rotates with the stirring blade 400.

[0052] The scraper 430 is made of rubber, which prevents damage to the inner wall of the treatment chamber 200 during cleaning. When the scraper 430 wears down due to rotation, the spring 501 can push the second frame 420 to move, so that the scraper 430 always fits against the inner wall of the treatment chamber 200. When the scraper 430 needs to be worn down too much, the nut 502 can be turned off the bolt 500. At this time, the second frame 420 can be moved to remove it from the bolt 500 to replace the worn scraper 430.

[0053] Specifically, the scraper 430 is installed on the side wall of the second frame 420 by adhesive. When the cleaning component is installed on the stirring blade 400, the stirring blade 400 at the bottom is still located in the processing chamber 200. At this time, under the pushing force of the spring 501, the scraper 430 can adhere to the inner wall of the processing chamber 200. As the scraper 430 moves down with the stirring blade 400, the remaining part of the scraper 430 can also adhere to the processing chamber 200, which is convenient for installation and use.

[0054] In this embodiment, when thallium-containing wastewater needs to be treated, firstly, the valve in the discharge pipe 201 is closed, and the thallium-containing wastewater and thallium removal agent are added to the treatment chamber 200 through the feeding pipe 141. The second motor 121 is started to rotate the rotating shaft 122, which drives the stirring blade 400 to rotate, thus mixing the thallium-containing wastewater and thallium removal agent. The first motor 113 is started to drive the extension plate 120 to rise and fall, so that the stirring blade 400 can stir the thallium-containing wastewater and thallium removal agent at different heights. After they are evenly mixed, the discharge pipe is opened. The valve inside the feed pipe 201 discharges the thallium-containing wastewater and thallium removal agent from the treatment chamber 200, allowing it to enter the sedimentation tank for sedimentation treatment. The top cover is removed from the top of the treatment cylinder 130, and then the semi-circular plates 140 are separated from each other so that the stirring blade 400 can extend from the upper opening of the treatment chamber 200. At this time, the cleaning component is installed on the stirring blade 400, and the stirring blade 400 is lowered into the treatment chamber 200, so that the scraper 430 rotates with the stirring blade 400 to clean the side wall of the treatment chamber 200.

[0055] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
