Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater, in particular to a high-efficiency membrane treatment device for electroplating wastewater reuse. Background Art

[0002] The treatment and reuse of electroplating wastewater plays a vital role in saving water resources and protecting the environment. The water quality of electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions and cyanide such as chromium, cadmium, nickel, copper, zinc, gold, silver, etc. Some of them are highly toxic substances that are carcinogenic, teratogenic, and mutagenic. Among them, membrane separation technology, such as reverse osmosis and nanofiltration, is used for deep purification of the treated wastewater for reuse or discharge in compliance with standards.

[0003] A Chinese patent application CN202021193247.7 discloses a device for treating and reusing electroplating wastewater. The key points of its technical solution are as follows: The utility model can precipitate most of the metal substances in the wastewater through chemical treatment, and filter them out through a filtering device. Then, the residual metal ions with high activity can be removed through an electrolytic cell. Then, biological treatment in an aeration treatment tank can remove harmful substances in the wastewater to the maximum extent. Finally, the wastewater is thoroughly purified through RO reverse osmosis membrane tubes.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: due to the treatment of wastewater, the electroplating wastewater treatment device will be in a humid environment for a long time, so that water vapor in the air will continuously enter the inside of the control box, causing short circuit failure of the electrical components inside the control box, resulting in the electroplating wastewater treatment device being unable to operate normally; therefore, in view of the above-mentioned problems, an efficient membrane treatment device for electroplating wastewater reuse is proposed.

[0007] The effect achieved by the above-mentioned components is: by setting up a protective device, the interior of the control box is moisture-proofed.

[0008] Preferably, a placement block is fixedly connected to the side wall of the connecting plate, a sliding rod is slidably inserted in the placement block, and one end of the sliding rod is fixedly connected to the limit block.

[0009] The effects achieved by the above components are: preventing the limit block from rotating with the rotation of the screw rod, thereby improving the stability of the device.

[0010] Preferably, one end of the screw rod away from the limiting block is fixedly connected to a handle, and the arc surface of the handle has a plurality of protrusions.

[0011] The effect achieved by the above components is: to facilitate the operation of the staff to quickly rotate the screw to control the position of the limit block.

[0012] Preferably, a sealing gasket is fixedly connected to the surface of the placement bin, and the size of the limiting block is matched with the size of the limiting groove of the mounting plate.

[0013] The effect achieved by the above components is: preventing the powder in the quicklime reaction process in the storage bin from entering the control box through the gap between the fixed bin and the storage bin.

[0017] The effect achieved by the above components is: by setting the adjustment device, the position of the box door is limited, so that the staff can repair the parts in the control box, prevent the box door from shaking during the maintenance process and hinder the operation, thereby improving the stability of the device.

[0018] Preferably, a spring is fixedly connected to one side of the fixing block close to the elliptical plate, and one end of the spring is fixedly connected to one side of the elliptical plate close to the fixing block.

[0020] In summary, the beneficial effects of the utility model are:

[0021] 1. In the utility model, by setting a protective device, the interior of the control box is protected from moisture. Since the electroplating wastewater treatment device treats wastewater in a humid environment for a long time, water vapor in the air will continuously enter the interior of the control box, causing short-circuit failure of electrical components inside the control box, resulting in the electroplating wastewater treatment device being unable to operate normally, thereby improving the practicability of the device.

In the utility model, by setting the adjustment device, the effect of limiting the position of the box door is achieved, so that the staff can repair the parts in the control box and prevent the box door from shaking during the repair process to hinder the operation, thereby improving the stability of the device.

[0028] Reference Figure 1 As shown, the utility model provides a technical solution: a high-efficiency membrane treatment device for electroplating wastewater reuse, comprising an electroplating wastewater treatment device 1, a control box 2 is installed on the surface of the electroplating wastewater treatment device 1, a box door 3 is rotatably connected to the surface of the control box 2, and a protective device 4 is provided on the inner surface of the control box 2. By setting the protective device 4, the interior of the control box 2 is protected from moisture. Since the electroplating wastewater treatment device 1 treats wastewater in a humid environment for a long time, water vapor in the air will continuously enter the interior of the control box 2, resulting in a short circuit failure of the electrical components inside the control box 2, resulting in the electroplating wastewater treatment device 1 being unable to operate normally, thereby improving the practicability of the device. An adjusting device 5 is provided on the surface of the control box 2. By setting the adjusting device 5, the effect of limiting the position of the box door 3 is achieved, so that the staff can repair the parts in the control box 2 body, and prevent the box door 3 from shaking during the repair process to hinder the operation, thereby improving the stability of the device.

[0029] The specific settings and functions of the protective device 4 and the regulating device 5 are described in detail below.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the protective device 4 includes a fixed bin 401, which is fixedly connected to the inner surface of the control box 2, and a slide groove is provided on the inner surface of the control box 2. A slide plate 402 is slidably connected to the inner surface of the slide groove of the control box 2, and a placement bin 403 is fixedly connected to one side of the slide plate 402. A plurality of air holes are provided on the surface of the fixed bin 401, and a connecting plate 404 is fixedly connected to one side of the fixed bin 401. A screw 405 is inserted into the inner thread of the connecting plate 404, and one end of the screw 405 is rotatably connected to a limiting block 406. A mounting plate 407 is fixedly connected to one side of the placement bin 403, and a limiting groove is provided on the surface of the mounting plate 407. A placement block 408 is fixedly connected to the side wall of the connecting plate 404, and a slide rod 409 is slidably inserted into the placement block 408, and one end of the slide rod 409 is fixedly connected to the limiting block 406. The screw rod 405 is rotated in the connecting plate 404, the screw rod 405 drives the limit block 406 to move, and the limit block 406 drives the slide bar 409 to slide in the placement block 408, so as to avoid the limit block 406 rotating with the rotation of the screw rod 405, thereby improving the stability of the device. The end of the screw rod 405 away from the limit block 406 is fixedly connected with a handle 410, and the arc surface of the handle 410 has several convex points. The handle 410 is rotated to drive the screw rod 405 to rotate in the connecting plate 404, and the screw rod 405 drives the limit block 406 to move, so that the staff can quickly rotate the screw 405 to control the position of the limit block 406. The surface of the placement bin 403 is fixedly connected with a sealing pad 411, and the size of the limit block 406 is adapted to the size of the limit groove of the mounting plate 407. Pushing the placement bin 403 drives the slide plate 402 to slide on the inner surface of the slide groove of the fixed bin 401, and the placement bin 403 drives the sealing pad 411 to move, thereby preventing the powder in the quicklime reaction process in the placement bin 403 from entering the control box 2 from the gap between the fixed bin 401 and the placement bin 403. Two alignment plates 412 are fixedly connected to the surface of the fixed bin 401, and the size of the slide plate 402 matches the size of the slide groove of the fixed bin 401. Pushing the placement bin 403 drives the slide plate 402 to slide on the inner surfaces of the two alignment plates 412, so that the staff can quickly install the placement bin 403, thereby improving the convenience of the device.

[0031] Reference Figure 4As shown, specifically, the adjustment device 5 includes an elliptical plate 51, a short rod 52 is slidably inserted in the elliptical plate 51, one end of the short rod 52 is fixedly connected to a fixing block 53, an L-shaped plate 55 is fixedly connected to the surface of the box door 3, one side of the L-shaped plate 55 is fixedly connected to a long plate 54, a slot is provided on the surface of the long plate 54, the size of the slot of the long plate 54 matches the size of the short rod 52, a spring 56 is fixedly connected to the side of the fixing block 53 close to the elliptical plate 51, and one end of the spring 56 is fixedly connected to the side of the elliptical plate 51 close to the fixing block 53. Pulling the box door 3 drives the L-shaped plate 55 to move, and the L-shaped plate 55 drives the long plate 54 to move, and the long plate 54 is squeezed with the short rod 52, at which time the short rod 52 slides in the elliptical plate 51, and the spring 56 is in a stretched state, until the short rod 52 is aligned with the position of the slot of the long plate 54, the elastic force of the spring 56 drives the short rod 52 to slide in the elliptical plate 51 and automatically insert into the slot of the long plate 54, thereby improving the quickness of the device.

[0032] Working principle: when the staff needs to make the interior of the control box 2 moisture-proof, they place quicklime on the inner surface of the movable bin, and then push the placement bin 403 to drive the slide plate 402 to slide on the inner surface of the slide groove of the fixed bin 401. The placement bin 403 drives the sealing gasket 411 to move, and the handle 410 is turned to drive the screw 405 to rotate in the connecting plate 404. The screw 405 drives the limit block 406 to move, so that the staff can quickly turn the screw 405 to control the position of the limit block 406 until the limit block 406 is inserted into the limit groove of the mounting plate 407, thereby achieving the effect of moisture-proofing the interior of the control box 2. Because the electroplating wastewater treatment device 1 treats wastewater in a humid environment for a long time, water vapor in the air will continuously enter the interior of the control box, causing a short circuit failure of the electrical components inside the control box 2, resulting in the normal operation of the electroplating wastewater treatment device 1, thereby improving the practicality of the device.

[0033] When the staff needs to repair the electrical components in the control box 2, they pull the box door 3 to drive the L-shaped plate 55 to move, and the L-shaped plate 55 drives the long plate 54 to move. The long plate 54 is squeezed by the short rod 52, and the short rod 52 slides in the elliptical plate 51. At this time, the spring 56 is in a stretched state. Until the short rod 52 and the long plate 54 slot are aligned, the elastic force of the spring 56 drives the short rod 52 to slide in the elliptical plate 51 and automatically insert into the long plate 54 slot, thereby achieving the effect of limiting the position of the box door 3, so as to facilitate the staff to repair the parts in the control box 2 body, prevent the box door 3 from shaking during the repair process to hinder the operation, and improve the stability of the device.
