Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment device technology, and in particular to a wastewater electron beam irradiation degradation device with an adjustable irradiation plate angle. Background Technology

[0002] Wastewater treatment is an important field of environmental engineering. Its main purpose is to remove or reduce pollutants in wastewater to acceptable levels so that it can be safely discharged or reused.

[0003] Traditional wastewater treatment methods, such as chemical treatment, biological treatment, adsorption, and photocatalytic oxidation, are no longer sufficient to purify wastewater, especially persistent, biologically active, and bioaccumulative wastewater. In the wastewater treatment process, an electron beam irradiation degradation device is used to remove pollutants from the wastewater. This device includes a sedimentation tank, a guide plate, an irradiation plate fixed below the guide plate, and a collection tank. The guide plate guides the wastewater in the sedimentation tank to the irradiation plate, where it is irradiated to remove pollutants before flowing into the collection tank.

[0004] When treating wastewater of different flow rates or pollution levels, it is necessary to manually adjust the guide plates so that the fixed irradiation plates can treat the corresponding flow rates and pollution levels of wastewater. This reduces the wastewater treatment efficiency while treating the wastewater, and needs to be improved. Utility Model Content

[0005] To improve wastewater treatment efficiency, this invention provides a wastewater electron beam irradiation degradation device with an adjustable irradiation plate angle.

[0006] In a first aspect, this utility model provides a wastewater electron beam irradiation degradation device with an adjustable irradiation plate angle, employing the following technical solution:

[0007] An adjustable irradiation plate angle wastewater electron beam irradiation degradation device includes a sedimentation tank for storing wastewater to be treated, a guide plate disposed on the sedimentation tank for guiding the flow of wastewater, an irradiation plate for removing pollutants from the wastewater, and a collection tank for collecting the irradiated wastewater. The irradiation plate is disposed above the collection tank, and a height adjustment component for adjusting the height and tilt angle of the irradiation plate is disposed between the irradiation plate and the collection tank.

[0008] The height adjustment assembly includes a rotating part, a connecting part rotatably disposed at one end of the rotating part, a fixing part rotatably disposed at the other end of the rotating part and connected to the collection pool, and a fixing member connecting the connecting part and the irradiation plate. When the rotating part rotates, the connecting part moves towards or away from the rotating part.

[0009] By adopting the above technical solution, and by setting a height adjustment component between the collection tank and the irradiation plate, the angle of the irradiation plate can be adjusted, and the irradiation plate at different angles outputs different irradiation powers. Thus, while changing the irradiation area of ​​the irradiation plate, it can irradiate sewage with different flow rates, thereby improving sewage treatment efficiency. Furthermore, by rotating the rotating part, the connecting part and the rotating part can move towards each other or away from each other, which facilitates the operator to adjust the angle of the irradiation plate.

[0010] Optionally, the fixing member includes a spherical fixing block that is snapped onto the irradiation plate and a fixing rod disposed on the spherical fixing block and connected to the connecting part, wherein the irradiation plate is provided with a spherical groove for placing the spherical fixing block;

[0011] The spherical fixing block has a fixing groove for installing the fixing rod, the fixing rod has a fixing ring circumferentially arranged, and the spherical fixing block has an annular fixing groove for installing and fixing the fixing ring.

[0012] By adopting the above technical solution, when the irradiation plate is adjusted in angle, the spherical fixing block on the fixing member is engaged in the spherical groove, thereby enabling the irradiation plate to be connected to the connecting part while allowing the angle between the irradiation plate and the connecting part to change flexibly. The fixing rod is connected to the fixing groove to facilitate the engagement of the spherical fixing block in the spherical groove and to facilitate the connection between the spherical fixing block and the connecting part. The fixing rod is pre-fixed on the spherical fixing block by the one-to-one corresponding fixing ring and the annular fixing groove.

[0013] Optionally, the irradiation plate is provided with an annular component at the opening of the spherical groove for limiting the spherical fixing block. An installation block is provided on the outer side wall of the annular component, and a guide block is provided on the outer side wall of the annular component away from the installation block for facilitating the installation of the annular component. The inner wall of the spherical groove is symmetrically provided with installation grooves for installing the installation block and the guide block. The guide block has an inclined guide surface, and the annular component has a through hole for the fixing rod to pass through.

[0014] By adopting the above technical solution, by setting an annular part at the opening of the spherical groove, the spherical fixing block can be confined within the spherical groove. Furthermore, the annular part can be fixed at the opening of the spherical groove by the mounting block and the mounting groove. The guide block on the annular part facilitates the installation of the annular part, and the through hole on the annular part can limit the spherical fixing block while allowing the angle between the irradiation plate and the connecting part to change.

[0015] Optionally, the fixing rod has a mounting cavity, and a locking rod is rotatably connected within the mounting cavity;

[0016] The spherical fixing block has a placement groove, and the fixing rod has a fixing through groove that extends through the inner and outer surfaces and is used for the end of the locking rod to pass through and be inserted into the placement groove; when the fixing rod and the spherical fixing block are not engaged, the end of the locking rod is located in the mounting cavity.

[0017] By adopting the above technical solution, when the locking rod in the installation cavity passes through and is inserted into the placement groove to fix the through groove, the fixing rod can be snapped and fixed on the spherical fixing block. When the fixing rod and the spherical fixing block are not installed together, the end of the locking rod is located in the installation cavity to facilitate the installation of the fixing rod and the spherical fixing block.

[0018] Optionally, the locking rod includes a fixed end rotatably connected to the mounting cavity and a connecting end integrally connected to the fixed end. The connecting end is provided with a sliding magnet, which is always slidably attracted to the inner wall of the mounting cavity on the side away from the fixed end.

[0019] By adopting the above technical solution, the connecting end is slidably attracted to the inner wall of the mounting cavity away from the fixed end by the sliding magnet, so that the locking rod can always remain tilted in the mounting cavity.

[0020] Optionally, the fixing rod is provided with a driving assembly for driving the locking rod into the spherical fixing block.

[0021] By adopting the above technical solution, the locking rod is driven into the placement groove on the spherical fixing block by the driving component, so as to achieve the fixing rod and the spherical fixing block are fixed together.

[0022] Optionally, the drive assembly includes a rotating rod threadedly connected to the mounting cavity and abutting against the locking rod, a drive rod telescopically disposed on the rotating rod and used to drive the rotating rod to rotate, and a return spring disposed between the rotating rod and the drive rod, wherein the return spring drives the drive rod to always have a tendency to extend out of the rotating rod; the rotating rod is provided with a sliding groove for mounting the return spring and the drive rod.

[0023] By adopting the above technical solution, the rotating drive rod is rotated to drive the rotating rod to rotate, so that the rotating rod moves up and down in the mounting cavity to drive the connecting end of the locking rod to slide in the mounting cavity so that the locking rod passes through the fixed through groove. The return spring provided between the rotating rod and the drive rod can make the drive rod tend to extend out of the rotating rod so that the drive rod can drive the rotating rod to rotate.

[0024] Optionally, the drive rod is provided with a plurality of limiting blocks in the circumferential direction, and the rotating rod is provided with a limiting sliding groove for mounting the limiting blocks.

[0025] By adopting the above technical solution, the limiting block on the drive rod is installed in the limiting sliding groove, so that the limiting block can rotate at the same time when the drive rod rotates, and drive the rotating rod with the limiting sliding groove to rotate.

[0026] Optionally, a sliding groove for mounting the drive rod is provided on the outer side wall of the connecting part away from the collection pool. The groove opening of the sliding groove is provided with a mating slope, and the drive rod has a guide slope that mates with the mating slope to allow the drive rod to retract into the sliding groove.

[0027] By adopting the above technical solution, the sliding groove on the connecting part allows the drive rod to be conveniently set on the connecting part. The sliding groove's inclined surface and the drive rod's guide inclined surface allow the drive rod to retract into the sliding groove, facilitating its installation on the connecting part. Furthermore, the return spring within the sliding groove is compressed to continuously release elastic potential energy, thereby buffering the installation of the irradiation plate when it is mounted on the spherical fixing block. This reduces the downward pressure exerted by the irradiation plate on the height adjustment device, thus improving the service life of the height adjustment device.

[0028] Optionally, a limiting member is provided on the outer side wall of the drive rod, and the connecting part has a limiting groove on the inner wall of the sliding groove for the limiting member to slide and be installed.

[0029] By adopting the above technical solution, the driving rod can be further installed on the connecting part by installing the limiting part on the limiting part through the limiting part on the limiting part.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By installing a height adjustment component between the collection tank and the irradiation plate, the angle of the irradiation plate can be adjusted, and the irradiation plate at different angles outputs different irradiation powers. This allows the irradiation of wastewater with different flow rates to be irradiated while changing the irradiation area of ​​the irradiation plate, thereby improving the wastewater treatment efficiency. Furthermore, the rotation of the rotating part allows the connecting part to move towards or away from the rotating part, making it convenient for the operator to adjust the angle of the irradiation plate.

[0032] 2. When the locking rod in the mounting cavity passes through and is inserted into the fixing slot, the fixing rod can be snapped and fixed on the spherical fixing block. When the fixing rod and the spherical fixing block are not installed together, the end of the locking rod is located in the mounting cavity to facilitate the installation of the fixing rod and the spherical fixing block.

[0033] 3. By rotating the drive rod to drive the rotating rod to rotate, the rotating rod moves up and down in the mounting cavity, thereby causing the connecting end of the locking rod to slide in the mounting cavity so that the locking rod passes through the fixed through groove. The return spring provided between the rotating rod and the drive rod can make the drive rod tend to extend out of the rotating rod so that the drive rod can drive the rotating rod to rotate.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0041] Reference Figure 1This application discloses a wastewater electron beam irradiation degradation device with an adjustable irradiation plate angle, including a sedimentation tank 1 for storing wastewater to be treated, a guide plate 2 disposed on the sedimentation tank 1 for guiding the flow of wastewater, an irradiation plate 3 for removing pollutants from the wastewater, and a collection tank 4 for collecting the irradiated wastewater. The sedimentation tank 1 is connected to the collection tank 4 through the guide plate 2 so that the wastewater in the sedimentation tank 1 flows evenly to the collection tank 4.

[0042] Reference Figure 1 The guide plate 2 is equipped with a catalyst module for discharging catalyst. The catalyst is used in conjunction with the irradiation plate 3 to further catalyze the degradation of pollutants. When sewage flows on the guide plate 2, the catalyst module discharges a corresponding dose of catalyst through the flow rate of the water on the guide plate 2.

[0043] Reference Figure 1 The collection tank 4 is equipped with a cleaning device, which includes a motor, a fixed pulley, a filter screen, and a take-up roller. The motor is connected to the fixed pulley via a rope, and the fixed pulley is connected to the take-up roller via a rope. The filter screen is attached to the take-up roller. The fixed pulley is used to change the direction of the pulling force generated by the motor. The filter screen is used to intercept solid impurities in the sewage. The take-up roller, in conjunction with the motor's power, lifts the bottom of the filter screen collection tank 4, thereby facilitating the cleaning of impurities on the filter screen after it is lifted, and continuing the filtration of sewage.

[0044] Reference Figure 1 The irradiation plate 3 is positioned above the collection pool 4. Between the irradiation plate 3 and the collection pool 4, there is a height adjustment component 5 for adjusting the height and tilt angle of the irradiation plate 3, a fixing component 6 for connecting the height adjustment component 5 and the irradiation plate 3, an annular component 7 for limiting the fixing component 6, and a drive component 8.

[0045] Reference Figure 1 and Figure 2 The height adjustment components 5 are evenly arranged on the collection pool 4, thereby enabling multi-angle adjustment of the irradiation plate 3. The height adjustment components 5 include a rotating part 9, a connecting part 10, and a fixing part 11. The connecting part 10 is threadedly connected to one end of the rotating part 9, and the fixing part 11 is threadedly connected to the other end of the rotating part 9. The threads on the connecting part 10 are opposite to the threads on the fixing part 11, so that when the rotating part 9 rotates, the connecting part 10 and the rotating part 9 can move towards each other or away from each other. The connecting part 10 is threadedly connected to a connecting cover 12 at the end away from the rotating part 9. The connecting cover 12 is used to connect the irradiation plate 3 and the connecting part 10. The fixing part 11 is threadedly connected to a fixing cover 13 at the end away from the rotating part 9. The fixing cover 13 is welded to the collection pool 4 and is used to connect the collection pool 4 and the fixing part 11.

[0046] Reference Figure 2 and Figure 3The fixing member 6 is located between the connecting cover 12 and the irradiation plate 3 and is used to connect the irradiation plate 3 and the connecting cover 12. The fixing member 6 includes a spherical fixing block 14 and a fixing rod 15. The irradiation plate 3 has a spherical groove 16 on the side near the collection pool 4 for engaging the spherical fixing block 14. The spherical fixing block 14 is used to flexibly change the angle between the irradiation plate 3 and the connecting cover 12. The fixing rod 15 is used to facilitate the engagement of the spherical fixing block 14 with the spherical groove 16. The spherical fixing block 14 has a fixing groove 17 for installing the fixing rod 15. The fixing rod 15 has several fixing rings 18 along its length. The spherical fixing block 14 has an annular fixing groove 19 for installing and fixing the fixing rings 18. The annular fixing groove 19 and the fixing groove 17 are interconnected, and the annular fixing groove 19 corresponds one-to-one with the fixing rings 18. When the fixing rings 18 are installed in the annular fixing groove 19, the fixing rod 15 is pre-fixed on the spherical fixing block 14. In this embodiment, two fixing rings 18 are provided.

[0047] Reference Figure 3 and Figure 4 The annular part 7 is installed on the irradiation plate 3 at the opening of the spherical groove 16 and is used to limit the spherical fixing block 14. The annular part 7 has a through hole 21 for the fixing rod 15 to pass through. The inner wall of the through hole 21 does not abut against the outer wall of the fixing rod 15, and the diameter of the through hole 21 is always smaller than the diameter of the spherical fixing block 14.

[0048] Reference Figure 4 An mounting block 22 is provided on the outer side wall of the annular part 7. The mounting block 22 is used to fix the annular part 7 to the groove of the spherical groove 16. A guide block 23 is provided on the outer side wall of the annular part 7 away from the mounting block 22 to facilitate the installation of the annular part 7. The inner wall of the spherical groove 16 is symmetrically provided with mounting grooves 24 for inserting the mounting block 22 and the guide block 23. The guide block 23 has an inclined guide surface 25. When the annular part 7 is installed, the inclined guide surface 25 faces the irradiation plate 3, so that the guide block 23 can be easily inserted into the mounting groove 24.

[0049] Reference Figure 3 The fixing rod 15 has a mounting cavity 26, the opening of which faces the connecting cover 12. A locking rod 27 for locking the fixing rod 15 onto the spherical fixing block 14 is rotatably connected inside the mounting cavity 26. The locking rod 27 includes a fixing end 28 rotatably connected to the mounting cavity 26 and a connecting end 29 integrally connected to the fixing end 28. A sliding magnet 30 is integrally provided on the connecting end 29. The sliding magnet 30 is always slidably attracted to the inner side wall of the mounting cavity 26 away from the fixing end 28, so that the locking rod 27 and the mounting cavity 26 are always in an inclined state, thus making it less likely that the locking rod 27 will be perpendicular to the height direction of the mounting cavity 26, which facilitates the locking rod 27 to lock the fixing rod 15 and the spherical fixing block 14.

[0050] Reference Figure 5 The spherical fixing block 14 has a placement groove 31 for inserting the connecting end 29. The fixing rod 15 has a fixing through groove 32 on its side wall near the connecting end 29, which penetrates the inner and outer surfaces and is used for the connecting end 29 to pass through and insert into the placement groove 31. When the fixing rod 15 and the spherical fixing block 14 are not engaged, the connecting end 29 always slides and adheres to the inner side wall of the mounting cavity 26.

[0051] Reference Figure 3 and Figure 5 The drive assembly 8 is threadedly connected to the fixed rod 15 and is used to drive the connecting end 29 into the placement groove 31. The drive assembly 8 includes a rotating rod 33 threadedly connected to the mounting cavity 26 and abutting against the locking rod 27, a drive rod 34 telescopically mounted on the rotating rod 33 and used to drive the rotating rod 33 to rotate, and a return spring 35 disposed between the rotating rod 33 and the drive rod 34. The return spring 35 drives the drive rod 34 to always tend to extend out of the rotating rod 33. The rotating rod 33 is provided with a return spring. The spring 35 and the drive rod 34 are mounted in a sliding groove 36. The end of the drive rod 34 away from the rotating rod 33 is provided with several limiting blocks 37 in the circumferential direction. The limiting blocks 37 are used to limit the drive rod 34 within the sliding groove 36. The rotating rod 33 is provided with a limiting sliding groove 38 along the height direction for mounting the limiting blocks 37. The limiting sliding groove 38 is used for the drive rod 34 to slide along the height direction of the rotating rod 33. The limiting sliding groove 38 corresponds one-to-one with the limiting blocks 37 and the limiting sliding groove 38 and the sliding groove 36 are interconnected.

[0052] When the fixing rod 15 is installed in conjunction with the spherical fixing block 14, the driving rod 34 is manually rotated to drive the rotating rod 33 to rotate, so that the rotating rod 33 moves in the mounting cavity along the height direction of the fixing rod 15. When the rotating rod 33 abuts against the locking rod 27, the rotating rod 33 drives the connecting end 29 to slide on the side wall of the mounting cavity 26 until the connecting end 29 passes through the fixing through groove 32 and is inserted into the placement groove 31, thereby locking the fixing rod 15 onto the spherical fixing block 14.

[0053] Reference Figure 3 and Figure 5A sliding groove 39 for mounting the drive rod 34 is provided on the outer wall of the end of the connecting cover 12 away from the collection pool 4. The sliding groove 39 is perpendicular to the height direction of the connecting cover 12, allowing the drive rod 34 to slide laterally within the sliding groove 39. A mating slope 40 is provided at the opening of the sliding groove 39. The end of the drive rod 34 away from the rotating rod 33 has a guide slope 41 that engages with the mating slope 40 to allow the drive rod 34 to retract into the sliding groove 36. The mating slope 40 and the guide slope 41 have the same slope. When the connecting end 29 is inserted into the placement groove 31, the guide slope 41 faces the mating slope 40, and the guide slope 41 and the mating slope 40 abut against each other to drive the drive rod 34 to retract into the sliding groove 36.

[0054] Reference Figure 3 and Figure 4 A limiting member 42 is axially provided on the outer wall of the drive rod 34 away from the rotating rod 33. The connecting cover 12 has a limiting groove 43 on the inner wall of the sliding groove 39 for the limiting member 42 to slide. When the drive rod 34 needs to be installed on the connecting cover 12, when the drive rod 34 retracts to the sliding groove 36, the limiting member 42 corresponds exactly to the limiting groove 43, and the return spring 35 in the sliding groove 36 is compressed to continuously release elastic potential energy. This buffers the installation of the irradiation plate 3 on the spherical fixing block 14, reduces the downward pressure of the irradiation plate 3 on the height adjustment device, and improves the service life of the height adjustment device.

[0055] The installation process of a wastewater electron beam irradiation degradation device with an adjustable irradiation plate angle according to an embodiment of the present invention is as follows:

[0056] 1. One end of the fixing part 11 is threaded to the fixing cover 13, the other end of the fixing part 11 is threaded to one end of the rotating part 9, the other end of the rotating part 9 is threaded to one end of the connecting part 10, and the other end of the connecting part 10 is threaded to the connecting cover 12.

[0057] 2. Insert one end of the fixed rod 15 with the fixed ring 18 into the fixed groove 17 of the spherical fixed block 14, and thread the rotating rod 33 onto the fixed rod 15 until the connecting end 29 is inserted into the placement groove 31. Then, put the ring 7 onto the fixed rod 15, and then slide the driving rod 34 laterally into the sliding mating groove 39.

[0058] 3. When the drive rod 34 is positioned on the connecting cover 12, install the spherical groove 16 on the irradiation plate 3 in a one-to-one correspondence with the spherical fixing block 14, then insert the mounting block 22 on the annular part 7 into the mounting groove 24, and press the position of the guide block 23 on the annular part 7 towards the spherical fixing block 14. When the guide block 23 is inserted into the mounting groove 24, the installation is completed.

[0059] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
