Description

Technical Field

[0001] The utility model relates to the technical field of zero discharge of desulfurized waste water, in particular to a zero discharge treatment device for desulfurized waste water. Background Technique

[0002] A large amount of waste water is often generated during the desulfurization process. This waste water contains various pollutants such as ammonia, sulfates and heavy metals. Traditional treatment methods are difficult to meet the requirements of zero discharge. Therefore, it is necessary to develop more efficient treatment devices to solve the problem of industrial waste water treatment. There are some useful resources in the waste water. The zero discharge treatment device can not only solve the waste water treatment problem, but also realize resource recovery, reduce production costs and improve economic benefits.

[0003] At present, when most of the zero discharge treatment devices for desulfurized waste water on the market are in use, the desulfurized waste water may contain various solid particles, precipitates and chemical substances, which easily cause the filter screen to be blocked. If the zero discharge treatment device for desulfurized waste water does not set up a filter screen cleaning device, it will lead to the phenomenon that the filter screen is blocked due to long-term work, thus reducing the treatment efficiency of the treatment device.

[0026] Referring to Figure 1 - Figure 3 , which is an embodiment of the present utility model, provides a desulfurized wastewater zero-emission treatment device, including a main frame unit 100 and a stirring and cleaning unit 200.

[0027] The main frame unit 100 includes a processing box 101 and a plurality of support seats 102 fixedly connected to the four corners of the bottom of the processing box 101. One upper end of the side wall of the processing box 101 is fixedly communicated with a water inlet pipe 103, and a first water stop valve 104 is fixedly connected to the water inlet pipe 103. One lower end of the side wall of the processing box 101 far from the water inlet pipe 103 is fixedly communicated with a water outlet pipe 105, and a second water stop valve 106 is fixedly installed on the water outlet pipe 105. One upper end of the processing box 101 is fixedly communicated with a medicine inlet pipe 107, and a third water stop valve 108 is fixedly connected to the medicine inlet pipe 107. A controller 109 is fixedly installed on one side wall of the processing box 101;

[0028] The stirring and cleaning unit 200 includes a driving motor 201 fixedly connected to the upper end of the processing box 101. The output shaft of the driving motor 201 penetrates through the upper end of the processing box 101 and is fixedly connected with a rotating rod 202. One end of the rotating rod 202 far from the driving motor 201 is fixedly connected with a fan blade 203. A fixing plate 204 is horizontally and fixedly installed on the inner side wall of the processing box 101. A plurality of uniformly distributed water outlet holes are fixedly opened on the fixing plate 204. One end of the inner side wall of the processing box 101 far from the fixing plate 204 is fixedly connected with a filter screen 205. One side wall of the processing box 101 far from the water outlet pipe 105 is fixedly connected with a support plate 206. A servo motor 207 is fixedly installed on the support plate 206. A threaded rod 208 is fixedly connected to the output shaft of the servo motor 207. A moving block 209 is threadedly connected to the threaded rod 208. A connecting plate 210 is fixedly connected to the lower end of the moving block 209. A brush 211 is fixedly installed at the bottom of the connecting plate 210. The brush 211 abuts against the filter screen 205, and the length of the brush 211 is the same as the width of the filter screen 205;

[0029] A limiting rod 212 is horizontally and fixedly installed on the inner side wall of the processing box 101. The limiting rod 212 penetrates through the side wall of the moving block 209, and the limiting rod 212 is slidably connected with the moving block 209. Hydraulic telescopic rods 213 are symmetrically and fixedly connected to the inner side wall of the processing box 101. A fixing block 214 is fixedly connected to the upper end of the hydraulic telescopic rod 213. A moving plate 215 is fixedly connected to the upper end of the fixing block 214. A plurality of uniformly distributed water outlet holes are fixedly opened on the moving plate 215. The size of each water outlet hole is matched with the water outlet holes fixedly opened on the fixing plate 204. The length of the fixing plate 204 is longer than the length of the moving plate 215. One end of the threaded rod 208 far from the servo motor 207 is slidably connected to one side wall of the processing box 101. The rotating rod 202, the threaded rod 208, the fixing plate 204 and the moving plate 215 are all made of anti-corrosion materials, and the fixing plate 204 is hermetically and slidably connected with the moving plate 215.

[0030] During use, when a zero-discharge treatment device for desulfurized wastewater is working, the wastewater enters the treatment tank 101 through the water inlet pipe 103. Open the third water stop valve 108, and add treatment chemicals into the treatment tank 101 through the chemical inlet pipe 107. Then start the drive motor 201. By the rotation of the output shaft of the drive motor 201, the rotating rod 202 fixedly connected to the output shaft of the drive motor 201 rotates, so that the fan blade 203 fixedly connected to the bottom of the rotating rod 202 rotates. By the rotation of the fan blade 203, the wastewater is stirred, so that the wastewater can fully contact the treatment chemicals. Then start the hydraulic telescopic rod 213. By the telescopic movement of the hydraulic telescopic rod 213, the fixed block 214 fixedly connected to the upper end of the hydraulic telescopic rod 213 moves, so that the moving plate 215 fixedly connected to the upper end of the fixed block 214 moves;

[0031] Thus, the water outlet fixedly opened on the moving plate 215 coincides with the water outlet fixedly opened on the fixed plate 204, so that the wastewater at the upper end of the fixed plate 204 falls on the filter screen 205 through the water outlet. The wastewater is filtered by the filter screen 205. When there are impurities on the filter screen 205, start the servo motor 207. By the rotation of the output shaft of the servo motor 207, the threaded rod 208 fixedly connected to the output shaft of the servo motor 207 rotates, so that the moving block 209 threadedly connected to the threaded rod 208 moves, so that the brush 211 fixedly connected to the bottom of the moving block 209 moves. Since the brush 211 abuts against the upper end of the filter screen 205, the filter screen 205 is cleaned, preventing the occurrence of the phenomenon that the filter screen 205 is blocked due to long-term operation, thereby reducing the treatment efficiency of the treatment device.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
