Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a heavy metal ion adsorption and removal device for wastewater based on an adsorbent. Background Technology

[0002] In the treatment of heavy metal wastewater, adsorption is a common method. Its principle is to use special materials to adsorb heavy metal ions in the wastewater, thereby achieving the purpose of treating the heavy metals in the water. Commonly used adsorbents include resins, zeolites, diatomaceous earth, chitosan-based adsorbents, and activated carbon.

[0003] In existing heavy metal wastewater treatment methods, the effectiveness of activated carbon or chitosan adsorbents gradually decreases after prolonged use. Once the effectiveness decreases, manual removal and replacement are required, which necessitates shutdown of the system, affecting wastewater treatment efficiency. Furthermore, the process of inserting and removing the adsorbents is inconvenient. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a heavy metal ion adsorption and removal device for wastewater based on an adsorbent, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heavy metal ion adsorption and removal device for wastewater based on an adsorbent, comprising a shell, an adsorption tank one, and an adsorption tank two.

[0006] The inner wall of the outer shell is fitted with a water receiving tank via a support frame three, and the bottom end face of the water receiving tank is respectively embedded and fixed with a liquid outlet pipe one and a liquid outlet pipe two.

[0007] Both adsorption box one and adsorption box two are fitted with frames, and the adsorbent body is installed inside the frames.

[0008] The rear end faces of both adsorption box one and adsorption box two are welded with fixing frames.

[0009] A drive mechanism is installed on the bottom surface of the inner wall of the fixed frame, and a lead screw is provided on the output shaft of the drive mechanism.

[0010] A connecting frame is welded onto the frame;

[0011] The adsorption box one and adsorption box two are respectively installed inside the outer shell via support frame two and support frame one.

[0012] Preferably, both the first and second outlet pipes are connected to the liquid in the receiving tank, and both outlet pipes are equipped with valves via flanges. Wastewater collected from the receiving tank can be discharged by individually opening the valve on either outlet pipe or outlet pipe.

[0013] Preferably, a support block is welded to the bottom surface of the outer casing, and a mounting base is installed on the bottom surface of the support block. The outer casing can be installed and supported by the cooperation of the support block and the mounting base.

[0014] Preferably, a discharge pipe is embedded and fixed at the bottom end face of both adsorption tank one and adsorption tank two, and the discharge pipe is in liquid communication with adsorption tank one and adsorption tank two. The wastewater after adsorption treatment in adsorption tank one and adsorption tank two can be discharged through the discharge pipe.

[0015] Preferably, a drain pipe is embedded and fixed on the side end face of adsorption tank one, and a drain pipe is embedded and fixed on the side end face of adsorption tank two. Wastewater can be guided into adsorption tank one and adsorption tank two through drain pipe one and drain pipe two.

[0016] Preferably, the end of the first drain pipe facing away from the first adsorption tank is installed inside the first outlet pipe, and the end of the second drain pipe facing away from the second adsorption tank is installed inside the second outlet pipe. The first drain pipe and the second drain pipe can be connected to the first outlet pipe and the second outlet pipe respectively, and after connection, the wastewater in the receiving tank can be discharged into the first adsorption tank or the second adsorption tank respectively.

[0017] Preferably, a guide block is welded to one end of the connecting frame away from the main frame. The guide block is slidably sleeved within the fixed frame and is threaded onto the lead screw. The guide block's slidable sleeve within the fixed frame provides a limiting position. When this position is achieved, the guide block's threaded mounting on the lead screw allows a person to open the drive mechanism and rotate the lead screw. The rotation direction of the lead screw causes the guide block and connecting frame to move up and down, thereby moving the main frame up and down within adsorption boxes one and two.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model, by setting up adsorption tank one and adsorption tank two, allows workers to use pumps or other equipment to draw wastewater through pipes and inject it into a receiving tank during the wastewater treatment and adsorption process. After the wastewater is injected into the receiving tank, adsorption tank one and adsorption tank two can be used as backup options. In this way, wastewater can be injected into adsorption tank one or adsorption tank two separately by opening the valves on outlet pipe one and outlet pipe two, through drain pipe one and drain pipe two. During this process, the wastewater passes through the adsorbent in adsorption tank one or adsorption tank two, thereby achieving the adsorption and removal of heavy metal ions. By making adsorption tank one and adsorption tank two backups for each other, downtime due to maintenance or repair of a single treatment tank can be effectively avoided.

[0020] 2. This utility model, by setting up a frame, prevents the adsorbent in adsorption tanks one and two from affecting the removal effect due to prolonged adsorption during the wastewater treatment and adsorption process. At this time, the operator activates the drive mechanism, which in turn rotates the lead screw. According to the rotation direction of the lead screw, the guide block and connecting frame move up and down, thereby moving the frame up and down within adsorption tanks one and two, thus unfolding the adsorbent. This facilitates later maintenance and replacement of the adsorbent, avoiding the inconvenience of needing to enter the adsorption tanks for inspection and replacement. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figures 1-5 As shown, the present invention proposes a heavy metal ion adsorption and removal device for wastewater based on an adsorbent, comprising a shell 4, an adsorption tank 6, and an adsorption tank 12.

[0030] The inner wall of the outer shell 4 is fitted with a water receiving tank 9 via a support frame 3 16, and the bottom end face of the water receiving tank 9 is respectively embedded and fixed with a liquid outlet pipe 1 8 and a liquid outlet pipe 2 10.

[0031] Both adsorption box 6 and adsorption box 12 are fitted with a frame 15, and the adsorbent body 14 is installed inside the frame 15. The adsorbent body 14 can be a chitosan adsorbent or activated carbon to adsorb heavy metal ions in wastewater.

[0032] Both the rear end faces of adsorption box 1 (6) and adsorption box 2 (12) are welded with fixing frames 20;

[0033] A drive mechanism 17 is installed on the bottom surface of the inner wall of the fixed frame 20, and a lead screw 19 is provided on the output shaft of the drive mechanism 17.

[0034] A connecting bracket 18 is welded onto the frame 15;

[0035] Adsorption box 16 and adsorption box 212 are respectively installed inside the outer shell 4 via support frame 23 and support frame 12.

[0036] Both the first outlet pipe 8 and the second outlet pipe 10 are connected to the liquid in the receiving tank 9, and both the first outlet pipe 8 and the second outlet pipe 10 are equipped with valves via flanges. By opening the valve on the first outlet pipe 8 or the second outlet pipe 10 individually, the wastewater collected in the receiving tank 9 can be discharged.

[0037] Both adsorption tank 6 and adsorption tank 12 have a discharge pipe 13 embedded and fixed at their bottom ends. The discharge pipe 13 is in liquid communication with adsorption tank 6 and adsorption tank 12. The wastewater after adsorption treatment in adsorption tank 6 and adsorption tank 12 can be discharged through the discharge pipe 13. During discharge, the wastewater can be discharged into a sedimentation tank or filtration treatment mechanism for further treatment before discharge, thus avoiding direct discharge that may affect the environment.

[0038] A drain pipe 7 is embedded and fixed on the side end face of adsorption box 6, and a drain pipe 11 is embedded and fixed on the side end face of adsorption box 12. Wastewater can be guided into adsorption box 6 and adsorption box 12 through drain pipe 7 and drain pipe 11.

[0039] One end of the drain pipe 7, which is away from the adsorption box 6, is installed inside the outlet pipe 8, and the other end of the drain pipe 11, which is away from the adsorption box 12, is installed inside the outlet pipe 10. The drain pipe 7 and the drain pipe 11 can be connected to the outlet pipe 8 and the outlet pipe 10 respectively. After connection, the wastewater in the water receiving tank 9 can be discharged into the adsorption box 6 or the adsorption box 12 respectively.

[0040] Based on Example 1: When treating wastewater, personnel can use a pump or other mechanism to draw the wastewater through a pipeline and inject it into the receiving tank 9. After being injected into the receiving tank 9, personnel can use adsorption tank 1 6 and adsorption tank 2 12 as backups for each other. This allows wastewater to be injected into adsorption tank 1 6 or adsorption tank 2 12 through drain pipe 1 7 and drain pipe 2 11 by opening the valves on drain pipe 1 8 and drain pipe 2 10. The wastewater is then removed by adsorption of heavy metal ions by the adsorbent body 14 in adsorption tank 1 6 or adsorption tank 2 12. Furthermore, by using adsorption tank 1 6 and adsorption tank 2 12 as backups for each other, the downtime caused by the need for maintenance of a single treatment tank is avoided.

[0041] Example 2

[0042] like Figures 1-5 As shown, the present invention proposes a heavy metal ion adsorption and removal device for wastewater based on an adsorbent. Compared with Embodiment 1, this embodiment further includes: a shell 4, an adsorption box 6, and an adsorption box 12.

[0043] The inner wall of the outer shell 4 is fitted with a water receiving tank 9 via a support frame 3 16, and the bottom end face of the water receiving tank 9 is respectively embedded and fixed with a liquid outlet pipe 1 8 and a liquid outlet pipe 2 10.

[0044] Both adsorption box 16 and adsorption box 212 are fitted with frames 15, and the adsorbent body 14 is installed inside the frames 15.

[0045] Both the rear end faces of adsorption box 1 (6) and adsorption box 2 (12) are welded with fixing frames 20;

[0046] A drive mechanism 17 is installed on the bottom surface of the inner wall of the fixed frame 20, and a lead screw 19 is provided on the output shaft of the drive mechanism 17.

[0047] A connecting bracket 18 is welded onto the frame 15;

[0048] Adsorption box 16 and adsorption box 212 are respectively installed inside the outer shell 4 via support frame 23 and support frame 12.

[0049] Furthermore, as is well known to those skilled in the art, the provision of the drive mechanism 17 is commonplace, falling under conventional means or common knowledge. The drive mechanism 17 can be powered and controlled by an external power supply and an external control switch, which will not be elaborated further here. Those skilled in the art can make any selection according to their needs or convenience. The drive mechanism 17 drives the lead screw 19 to rotate forward and in reverse.

[0050] A support block 1 is welded to the bottom surface of the outer shell 4, and a mounting base 5 is installed on the bottom surface of the support block 1. The outer shell 4 can be installed and supported by the cooperation of the support block 1 and the mounting base 5.

[0051] A guide block 21 is welded to one end of the connecting frame 18 away from the frame 15. The guide block 21 is slidably sleeved in the fixed frame 20 and is threaded onto the lead screw 19. The guide block 21 is slidably sleeved in the fixed frame 20 for limiting. When the limit is reached, the guide block 21 is threaded onto the lead screw 19, allowing the operator to open the drive mechanism 17 to rotate the lead screw 19. According to the rotation direction of the lead screw 19, the guide block 21 and the connecting frame 18 can move up and down, thereby causing the frame 15 to move up and down within the adsorption box 6 and the adsorption box 12.

[0052] Based on Example 2: When personnel are treating wastewater by adsorption, in order to avoid the adsorbent body 14 in adsorption box 1 6 and adsorption box 2 12 being adsorbed for a long time and affecting the removal effect, the personnel open the drive mechanism 17 to drive the lead screw 19 to rotate. According to the rotation direction of the lead screw 19, the guide block 21 and the connecting frame 18 can be driven to move up and down, thereby driving the frame 15 to move up and down in adsorption box 1 6 and adsorption box 2 12, thereby unfolding the adsorbent body 14, which is convenient for later maintenance and replacement, and avoids the inconvenience caused by probing for inspection and replacement.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
