Abstract
Description
Technical Field
[0001] The utility model relates to a wastewater treatment device, in particular to an electroplating wastewater treatment device. Background Art
[0002] A sedimentation tank is a process for sedimenting wastewater in electroplating wastewater treatment. After traditional electroplating wastewater is biodegradated, it is discharged into the sedimentation tank and the natural sedimentation method is used for pretreatment of the electroplating wastewater.
[0003] At present, in the electroplating wastewater treatment sedimentation tank used, impurities such as electroplating dregs will precipitate at the bottom of the tank after the wastewater is sedimented. In this way, when the sedimented electroplating wastewater is discharged, it often still contains impurities such as electroplating dregs, which affects the treatment effect of the subsequent electroplating wastewater. Therefore, chemicals can be added to make the impurities in the wastewater precipitate quickly. However, when the chemicals are directly added to the sedimentation tank, it is easy to have a situation where the chemicals and the wastewater cannot be fully contacted, affecting the filtration effect. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an electroplating wastewater treatment device that enables the chemicals and the wastewater to be fully contacted.
[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes a sedimentation tank, a contact chamber, a chemical box, a push rod, a cam, a rotating motor and a return spring. There is a communication port between the contact chamber and the sedimentation tank, and a filter screen is arranged on the communication port. The chemical box is slidably arranged in the contact chamber. One end of the push rod abuts against the chemical box, and the other end abuts against the cam. The rotating motor drives the cam to rotate and constitutes the drive of the push rod on the chemical box. The return spring is arranged between the contact chamber and the chemical box and drives the chemical box to abut against the push rod. It also includes a linkage rod. The cam includes a pushing part and a retracting part. The rotating motor drives the linkage rod to rotate. The other end of the linkage rod relative to the rotating motor is arranged at the center of the cam. The distance from the pushing part to the center of the cam is greater than the distance from the retracting part to the center of the cam.
[0006] By adopting the above technical solution, when in use, the medicament is placed in the medicament box. When the wastewater enters the contact chamber, the motor is rotated to drive the cam to rotate. At this time, the part in contact with the push rod gradually changes from the retraction part to the pushing part, so that the push rod in contact with the cam moves, driving the medicament box to move away from the cam until the cam rotates 90 degrees. Then, as the cam continues to rotate, the part in contact with the push rod gradually changes from the pushing part to the retraction part. At this time, under the action of the return spring, the push rod is always in contact with the cam and pushes the medicament box to reset. Every half turn the cam rotates, that is, the medicament box makes a complete swing, which can shake the medicament in the medicament box, making the medicament in the medicament box fully contact with the wastewater. Finally, it enters the sedimentation tank through the filter screen and then undergoes corresponding treatment. By the action of the medicament box, the contact between the medicament and the wastewater is increased, so that the sedimentation effect of the medicament on the wastewater is good and the impurities in the wastewater are reduced.
[0007] The present utility model is further arranged as: it further includes a sliding rod. A sliding hole for the sliding rod to pass through is provided on the medicament box. One end of the sliding rod is fixed in the contact chamber, and the other end passes through the sliding hole and is located inside the medicament box. A limiting block is provided at the end of the sliding rod relatively far from the contact chamber, and the return spring is sleeved on the sliding rod.
[0008] By adopting the above technical solution, the setting of the sliding rod satisfies the fixation of the sliding track of the medicament box in the contact chamber.
[0009] The present utility model is further arranged as: an arc end is provided on the side of the push rod relatively close to the cam.
[0010] By adopting the above technical solution, the setting of the arc end prevents jamming when the cam rotates and increases the smoothness of movement.
[0011] The present utility model is further arranged as: a plurality of through holes are provided at the bottom of the medicament box.
[0012] The present utility model is further arranged as: it further includes a preliminary filtration chamber. The preliminary filtration chamber is arranged on the top of the contact chamber. A filter plate is arranged between the preliminary filtration chamber and the contact chamber, and a liquid inlet is arranged at the top of the preliminary filtration chamber.
[0013] By adopting the above technical solution, before the wastewater enters the contact chamber, it is first preliminarily filtered by the filter plate to separate out larger impurities.
[0014] The present utility model is further arranged as: it further includes a fixing plate, a buffer cover and a buffer spring. The buffer spring is arranged in the preliminary filtration chamber. The buffer cover is located below the liquid inlet. The buffer spring is arranged between the buffer cover and the fixing plate and drives the buffer cover to move upward.
[0015] By adopting the above technical solution, when the wastewater enters the preliminary filtration chamber, it first contacts the buffer cover, compresses the buffer spring, thereby reducing the impact of the wastewater on the filter plate.
[0016] The present utility model is further configured such that: the buffer cover is frustum-shaped, and the radius of the upper base of the buffer cover is smaller than the radius of the lower base. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Such as Figures 1-4As shown in the figure, the utility model discloses an electroplating wastewater treatment device, which includes a sedimentation tank 1, a contact chamber 2, a medicine box 3, a push rod 4, a cam 5, a rotating motor 6 and a return spring 7. There is a communication port 11 between the contact chamber 2 and the sedimentation tank 1, and a filter screen 12 is arranged on the communication port 11. The medicine box 3 is slidably arranged in the contact chamber 2. One end of the push rod 4 abuts against the medicine box 3, and the other end abuts against the cam 5. The rotating motor 6 drives the cam 5 to rotate and constitutes the driving of the push rod 4 on the medicine box 3. The return spring 7 is arranged between the contact chamber 2 and the medicine box 3 and drives the medicine box 3 to abut against the push rod 4. It also includes a linkage rod 61. The cam 5 includes a pushing part 51 and a retracting part 52. The rotating motor 6 drives the linkage rod 61 to rotate. The other end of the linkage rod 61 relative to the rotating motor 6 is arranged at the center of the cam 5. The distance between the pushing part 51 and the center of the cam 5 is greater than the distance between the retracting part 52 and the center of the cam 5. When in use, put the medicine into the medicine box 3. When the wastewater enters the contact chamber 2, the rotating motor 6 drives the cam 5 to rotate. At this time, the part abutting against the push rod 4 gradually changes from the retracting part 52 to the pushing part 51, so that the push rod 4 abutting against the cam 5 moves, driving the medicine box 3 to move away from the cam 5 until the cam 5 rotates 90 degrees. Then, as the cam 5 continues to rotate, the part abutting against the push rod 4 gradually changes from the pushing part 51 to the retracting part 52. At this time, under the action of the return spring 7, the push rod 4 always abuts against the cam 5 and pushes the medicine box 3 to reset. Every half turn of the cam 5, that is, the medicine box 3 makes a complete swing, which can shake the medicine in the medicine box 3, make the medicine in the medicine box 3 fully contact with the wastewater, and finally enter the sedimentation tank 1 through the filter screen 12 for corresponding treatment. Through the action of the medicine box 3, the contact between the medicine and the wastewater is increased, so that the sedimentation effect of the medicine on the wastewater is good and the impurities in the wastewater are reduced.
[0025] It also includes a sliding rod 71. The medicine box 3 is provided with a sliding hole 72 for the sliding rod 71 to pass through. One end of the sliding rod 71 is fixed in the contact chamber 2, and the other end passes through the sliding hole 72 and is located in the medicine box 3. A limiting block 73 is arranged at the end of the sliding rod 71 relatively far from the contact chamber 2. The return spring 7 is sleeved on the sliding rod 71. The arrangement of the sliding rod 71 satisfies the fixation of the sliding track of the medicine box 3 in the contact chamber 2.
[0026] An arc end 41 is arranged on the side of the push rod 4 relatively close to the cam 5. The arrangement of the arc end 41 can prevent jamming when the cam 5 rotates and increase the smoothness of movement.
[0027] A plurality of through ports 31 are arranged at the bottom of the medicine box 3.
[0028] It further includes a preliminary filtration chamber 8, which is arranged at the top of the contact chamber 2. A filter plate 81 is provided between the preliminary filtration chamber 8 and the contact chamber 2. A liquid inlet 82 is provided at the top of the preliminary filtration chamber 8. Before the wastewater enters the contact chamber 2, it is preliminarily filtered by the filter plate 81 to separate out larger impurities first.
[0029] It further includes a fixing plate 83, a buffer cover 84 and a buffer spring 85. The buffer spring 85 is arranged inside the preliminary filtration chamber 8. The buffer cover 84 is located below the liquid inlet 82. The buffer spring 85 is arranged between the buffer cover 84 and the fixing plate 83 and drives the buffer cover 84 to move upward. When the wastewater enters the preliminary filtration chamber 8, it first contacts the buffer cover 84 and compresses the buffer spring 85, thereby reducing the impact of the wastewater on the filter plate 81.
[0030] The buffer cover 84 is frustum-shaped, and the radius of the upper bottom of the buffer cover 84 is smaller than the radius of the lower bottom.
[0031] Working process: When the wastewater enters the preliminary filtration chamber 8, it first contacts the buffer cover 84 and compresses the buffer spring 85, thereby reducing the impact of the wastewater on the filter plate 81. Then the wastewater passes through the filter plate 81 and enters the contact chamber 2. The rotating motor 6 drives the cam 5 to rotate. At this time, the part in contact with the push rod 4 gradually changes from the retraction part 52 to the pushing part 51, so that the push rod 4 in contact with the cam 5 moves, driving the medicine box 3 to move away from the cam 5 until the cam 5 rotates 90 degrees. Then as the cam 5 continues to rotate, the part in contact with the push rod 4 gradually changes from the pushing part 51 to the retraction part 52. At this time, under the action of the return spring 7, the push rod 4 always contacts the cam 5 and pushes the medicine box 3 to reset. Every time the cam 5 rotates half a circle, that is, the medicine box 3 swings once completely, the medicine in the medicine box 3 can be shaken, so that the medicine in the medicine box 3 is fully contacted with the wastewater, and finally it enters the sedimentation tank 1 through the filter net 12 and corresponding treatment is carried out.
