Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an electroplating wastewater treatment system. Background Art

[0002] The water quality of electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver, and cyanide, some of which are highly toxic substances that are carcinogenic, teratogenic, and mutagenic.

[0003] The existing electroplating wastewater needs to be filtered before deep treatment, so the corresponding electroplating wastewater filtering and treatment device needs to be used. In actual use, the existing electroplating wastewater filtering device is prone to clogging of the filter screen after long-term filtration, thereby affecting the filtering effect. The filter screen needs to be cleaned. The existing cleaning process requires disassembling the filter device and then removing the filter screen for cleaning, which is troublesome and affects efficiency. Therefore, we propose an electroplating wastewater treatment system. Utility Model Content

[0004] The purpose of the utility model is to provide an electroplating wastewater treatment system to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plating wastewater treatment system, comprising a box body, support plates are fixed on both sides of the top of the box body, a rotating shaft is rotatably installed between the two support plates, filter screens are fixed on the four sides of the outer wall of the rotating shaft, a servo motor is fixed on the outer wall of one of the support plates, and the transmission shaft of the servo motor passes through the support plate and is fixedly connected to one end of the rotating shaft.

[0006] By adopting the above technical solution, in actual use, one of the filter screens is placed in the inner cavity of the box, and the wastewater flowing inside the box is filtered through the filter screen. When the filter screen is seriously clogged during use, starting the servo motor can drive the shaft to rotate, thereby rotating the other filter screen by ninety degrees to the inner cavity of the box for filtering. At this time, the other filter screen is rotated to be parallel to the box, thereby facilitating the cleaning operation of the clogged filter screen.

[0007] As a preferred embodiment of the utility model, a negative pressure fan and a collecting box are fixedly installed on one side wall of the box body, the outer end of the negative pressure fan is connected to one side of the top of the collecting box, a filter screen is fixed on the upper side of the inner cavity of the collecting box, and a suction hood is provided on the upper side of the box body corresponding to the filter screen plate. The top of the suction hood is connected to a duct through a suction pipe, and the duct passes through the top of the collecting box and the filter screen.

[0008] By adopting the above technical solution, when the filter plate that needs to be cleaned is rotated to be parallel to the top of the box body, starting the negative pressure fan can generate negative pressure in the collection box, so that the impurities blocked on the surface of the filter plate can be sucked out by the suction hood, and the sucked out impurities will be collected in the collection box.

[0009] As a preferred embodiment of the present utility model, slide grooves are provided on both sides of the top of the box body, a screw motor is fixed to one end face of the inner cavity of the slide groove, a screw is fixedly connected to the outer end of the transmission shaft of the screw motor, the outer end of the screw is rotatably connected to the inner wall of the slide groove, the outer wall of the screw is provided with an adaptive screw slider, and one side wall of the screw slider is fixedly connected to the side wall of one end of the dirt suction hood through a connecting rod.

[0010] By adopting the above technical solution, during the rotation of the filter screen, the screw motor can be used to drive the screw to rotate, thereby driving the screw slider to move, so that the suction hood moves to the outside, thereby avoiding obstacles to the rotation of the filter screen. In addition, during the suction process, the suction hood moves back and forth to completely suck out impurities on the surface of the filter screen.

[0011] As a preferred embodiment of the present invention, a box cover is fixed to the front side wall of the collection box by bolts.

[0012] By adopting the above technical solution, the setting of the box cover makes it easy to disassemble, thereby facilitating the cleaning of the collected impurities.

[0013] As a preferred embodiment of the present utility model, an upper side of one end of the box body is fixedly connected to a water inlet pipe, and a lower side of the other end of the box body is fixedly connected to a drain pipe.

[0014] By adopting the above technical solution, the water inlet pipe can guide the waste water into the box, and the drain pipe can discharge the filtered water.

[0015] As a preferred embodiment of the present invention, the two side walls of the filter screen plate are attached to the two side walls of the inner cavity of the box body, and the bottom of the filter screen plate located at the lowermost side is attached to the bottom of the inner cavity of the box body.

[0016] By adopting the above technical solution, it is ensured that the filter screen plate can fully filter the wastewater flowing in the box.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The electroplating wastewater treatment system of the technical solution of the present application can drive the rotating shaft to rotate through the servo motor, thereby driving the filter screen plate to rotate, so that the clogged filter screen plate is rotated to the upper side, and the other filter screen plate is rotated into the box body for filtering. After the clogged filter screen plate is rotated to the upper side, the cleaning operation is convenient, and the continued filtering of the wastewater is not affected, thereby ensuring the efficiency of wastewater treatment;

[0019] The negative pressure fan can generate negative pressure in the collection box, so that the dirt suction hood can be used to suck out the clogged stains on the filter screen to achieve rapid cleaning. At the same time, the screw motor drives the screw slider to move back and forth, so that the dirt suction hood moves back and forth, thereby ensuring that the filter screen is completely cleaned of clogs.

[0029] In actual use, one of the filter screen plates 15 is placed in the inner cavity of the box body 1, and the waste water flowing inside the box body 1 is filtered through the filter screen plate 15. When the filter screen plate 15 is seriously blocked during use, the servo motor 16 is started to drive the rotating shaft 14 to rotate, so that the other filter screen plate 15 is rotated 90 degrees to the inner cavity of the box body 1 for filtering. At this time, the other filter screen plate 15 is rotated to be parallel to the box body 1, so that the blocked filter screen plate 15 can be cleaned conveniently;

[0030] Furthermore, the two side walls of the filter screen plate 15 are attached to the two side walls of the inner cavity of the box body 1, and the bottom of the filter screen plate 15 located at the bottom is attached to the bottom of the inner cavity of the box body 1, thereby ensuring that the filter screen plate 15 fully filters the wastewater flowing in the box body 1;

[0031] Furthermore, an inlet pipe 11 is fixedly connected to the upper side of one end of the box body 1, and a drain pipe 12 is fixedly connected to the lower side of the other end of the box body 1. The inlet pipe 11 can introduce waste water into the box body 1, and the drain pipe 12 can discharge filtered water;

[0032] like Figure 1 and 2 , 3; a negative pressure fan 33 and a collection box 31 are fixedly installed on one side wall of the box body 1, the outer end of the negative pressure fan 33 is connected to one side of the top of the collection box 31, a filter screen 34 is fixed on the upper side of the inner cavity of the collection box 31, a dirt suction hood 3 is provided at the upper side of the box body 1 corresponding to the filter screen plate 15, and the top of the dirt suction hood 3 is connected to a conduit 32 through a dirt suction pipe, and the conduit 32 runs through the top of the collection box 31 and the filter screen 34;

[0033] When the filter screen plate 15 to be cleaned rotates to be parallel to the top of the box body 1, the negative pressure fan 33 is started to generate negative pressure in the collection box 31, so that the impurities blocked on the surface of the filter screen plate 15 can be sucked out by the dirt suction hood 3, and the sucked out impurities will be collected in the collection box 31;

[0034] Furthermore, both sides of the top of the box body 1 are provided with a slide groove, a screw motor 2 is fixed to one end face of the inner cavity of the slide groove, a screw 21 is fixedly connected to the outer end of the transmission shaft of the screw motor 2, the outer end of the screw 21 is rotatably connected to the inner wall of the slide groove, an outer wall of the screw 21 is sleeved with an adapted screw slider 22, and one side wall of the screw slider 22 is fixedly connected to one end side wall of the dirt suction cover 3 through a connecting rod;

[0035] During the rotation of the filter screen 15, the screw motor 2 can drive the screw 21 to rotate, thereby driving the screw slider 22 to move, so that the dirt suction cover 3 moves to the outside, thereby avoiding the rotation obstacle of the filter screen 15. In addition, during the dirt suction process, the dirt suction cover 3 moves back and forth so that the impurities on the surface of the filter screen 15 can be completely sucked out;

[0037] The implementation principle of the electroplating wastewater treatment system of the present application is as follows: in actual use, one of the filter screen plates 15 is placed in the inner cavity of the box body 1, and the wastewater flowing inside the box body 1 is filtered through the filter screen plate 15. When the filter screen plate 15 is seriously blocked during use, the servo motor 16 is started to drive the rotating shaft 14 to rotate, so that the other filter screen plate 15 is rotated ninety degrees to the inner cavity of the box body 1 for filtering. At this time, the other filter screen plate 15 is rotated to be parallel to the box body 1. During the rotation of the filter screen plate 15, the screw motor 2 can be used to drive the screw 21 to rotate, thereby driving the filter screen plate 15 to rotate. The movable screw slider 22 moves, so that the dirt suction hood 3 moves to the outside, thereby avoiding obstruction to the rotation of the filter screen 15. When the filter screen 15 that needs to be cleaned rotates to be parallel to the top of the box body 1, starting the negative pressure fan 33 at this time can make the collection box 31 generate negative pressure, so that the dirt suction hood 3 can be used to suck out impurities blocked on the surface of the filter screen 15, and the sucked impurities will be collected in the collection box 31. In the process of sucking dirt, the screw motor 2 is used to drive the dirt suction hood 3 to move back and forth, so that the dirt suction hood 3 moves back and forth so that the impurities on the surface of the filter screen 15 can be sucked out completely.
