Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment devices, in particular to a wastewater pretreatment device which is easy to clean. Background Art

[0002] A certain amount of wastewater is often generated in industrial production. In the production process of ammonium molybdate, the acid washing process also produces a certain amount of wastewater containing certain chemical substances. It needs to be treated before it can be discharged in compliance with the standards or used in other processes, so a wastewater pretreatment device is needed.

[0003] Most of the pretreatment devices currently used are used in combination with a treatment box and a stirring device. Wastewater enters the device through a pipe, a neutralizer is added to the device, and then the wastewater is stirred by the stirring device, thereby achieving the purpose of neutralization treatment of the wastewater. In actual use, the stirring mechanism mainly includes a stirring rod and a motor. The stirring rod is connected to the motor. When cleaning the device, the stirring shaft is non-detachably connected to the box cover, which makes it inconvenient to clean it and also blocks the cleaning of the inside of the treatment box. It is inconvenient to use. After the wastewater is neutralized, a certain amount of impurities will be generated in the wastewater. The pretreatment device currently used is not equipped with a corresponding filtering device, which causes the generated impurities to be discharged together with the wastewater, which is very easy to block the drainage pipe. It is also inconvenient to treat and discharge the impurities separately, and the use effect is poor and the practicality is poor. Utility Model Content

[0019] The treatment box 4 is connected with a filter device, which is used to filter impurities in the water; the filter device includes a filter frame 7, a frame door 21 is connected to the front side of the filter frame 7, the filter frame 7 is threadedly connected to the first water outlet pipe 6, the filter frame 7 is connected to two mounting plates 10, the mounting plates 10 are provided with a plurality of groups of through holes 19, the two mounting plates 10 are slidably connected to the filter plate 11, and the bottom of the filter frame 7 is connected to the second water outlet pipe 12. The filter frame 7 is connected to a drive motor 14 and an auxiliary slide bar 20, the filter frame 7 is rotatably connected to a reciprocating screw 8, the output shaft of the drive motor 14 is connected to the reciprocating screw 8, the auxiliary slide bar 20 is arranged parallel to the reciprocating screw 8, the auxiliary slide bar 20 is located at the front side of the reciprocating screw 8, the reciprocating screw 8 is movably connected to a cleaning plate 13, the cleaning plate 13 is slidably connected to the auxiliary slide bar 20, the cleaning plate 13 is in conflict with the filter plate 11, and the left and right sides of the filter frame 7 are respectively slidably connected to a collection net frame 9.

[0020] The specific implementation process is as follows:

[0021] The waste water is discharged into the treatment box 4 through the water inlet pipe, and then the corresponding treatment agent is added through the drug inlet pipe. The servo motor 18 is started to drive the stirring rod 5 to rotate so that the waste water and the treatment agent are completely mixed and reacted. After the treatment is completed, the first water outlet pipe 6 and the driving motor 14 are opened, and the treated waste water and impurities are discharged into the filter frame 7 along the first water outlet pipe 6 and then flow to the filter plate 11. The impurities are filtered by the filter plate 11, and the treated waste water is discharged along the second water outlet pipe 12 through the filter frame 7. The driving motor 14 drives the reciprocating screw 8 to rotate, and the auxiliary sliding rod 20 plays a role of rotation limiting the cleaning plate 13. Therefore, as the reciprocating screw 8 rotates, the cleaning plate 13 moves back and forth along the reciprocating screw 8, and then scrapes the impurities on the filter plate 11 into the collecting net frames 9 on the left and right sides. The collecting net frames 9 can pass through water, and a small amount of water carried by the impurities entering the collecting net frame 9 can pass through the collecting net frame 9 and the through hole 19 along the second water outlet pipe 1212 water inlet and be discharged.

[0022] After use, the frame door 21 can be opened, and the collection net frame 9 can be taken out forward to collect the impurities for centralized treatment. After a period of use, the filter plate 11 can also be pulled out forward to clean the filter plate 11. The reciprocating screw rod 8 and the auxiliary slide rod 20 are respectively located at the rear and front sides below the first water outlet pipe 6, so the wastewater impurity mixture will not directly impact the reciprocating screw rod 8 and the auxiliary slide rod 20, thereby increasing the service life of the two.

[0023] After using it for a period of time, the staff can enter the treatment box 4 through the inlet and outlet hole 2. The treatment box 4 is generally large enough to facilitate the staff to move and clean it. The climbing ladder 3 is convenient for the staff to enter and exit. After entering the treatment box 4, the staff can remove the stirring shaft and send the stirring shaft out of the treatment box 4 for cleaning or concentrate all the stirring shafts in the middle of the treatment box 4 for centralized and separate cleaning so that it does not affect the staff's cleaning of the treatment box 4. The staff can push the scraper 15 to move to remove the auxiliary impurities on the inner wall of the treatment box 4, and then the staff can manually clean the treatment box 4 and the stirring rod 5. The waste water generated by cleaning is discharged from the first outlet pipe 6. After cleaning, the stirring rod 5 is connected and the treatment box 4 can be left through the climbing body and the inlet and outlet hole 2. For the convenience of cleaning, part of the box cover 1 can be made of transparent material.

The structure is simple and the practicality is greatly improved. A filter frame 7 and a filter net are provided to filter the impurities generated by the neutralization reaction to prevent the impurities from being discharged with the wastewater. The servo motor 18 drives the reciprocating screw rod 8 to drive the cleaning plate 13 to move back and forth to scrape the impurities on the filter plate 11, so as to avoid the impurities from being attached to the filter plate 11 for a long time and blocking the filter screen to affect the filtering effect and the discharge of wastewater, improve the treatment and discharge efficiency of the device, and do not need to frequently replace the filter screen, which is also convenient for the subsequent staff to clean the filter screen. A collection net frame 9 is set, and the impurities scraped by the cleaning plate 13 can be collected in the collection net frame 9, which is convenient for the subsequent separate treatment and discharge. The collection net frame 9 is directly placed in the filter frame 7, which can effectively collect impurities while filtering the wastewater frame 7, so that the wastewater can be discharged along the second outlet pipe 12, improve the stability of use, and protect the environment of the workplace. The mounting plate 10 is provided with a through hole 19, which is convenient for the complete discharge of a small amount of wastewater carried by the impurities in the collection net frame 9.
