Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device. Background Technology

Wastewater treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, catering, and many other fields. Modern wastewater treatment technologies, classified by treatment level, can be divided into primary, secondary, and tertiary treatment.

[0003] Publication number CN215876486U discloses a sewage treatment device. This patent has a reasonable design, simple structure, and convenient operation. It enables the filter screen to vibrate up and down, allowing solid impurities to enter the collection frame through the connecting holes for collection, thereby preventing filter screen clogging. However, this patent still has the following problems in actual use:

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This sewage treatment equipment has a filter assembly installed inside the primary sedimentation tank, which allows the filter plates to be cleared during sewage filtration, preventing blockage of the holes on the filter plates and avoiding affecting the normal filtration of sewage, ensuring the normal operation of sewage treatment, and improving practicality. The specific details are as follows:

[0020] 1. A filtration assembly is installed inside the primary sedimentation tank. During wastewater filtration, wastewater enters the primary sedimentation tank through the inlet pipe and is filtered by the filter plates. Impurities pass through the filter plates and channels to one side of the primary sedimentation tank and are subsequently discharged through the drain pipe. Simultaneously with wastewater filtration, a drive motor rotates a cam. The cam's rotation moves a mounting plate, which then slides on a support rod, stretching a telescopic spring. After one revolution of the cam, the spring returns to its original shape, resetting the mounting plate. This, in turn, causes the filter plates to reciprocate left and right. This reciprocating movement of the filter plates simultaneously transports the filtered impurities. The vertical movement of the filter plates... The filter plate moves left and right to better screen impurities, making it easier for them to leave the filter plate. The reciprocating movement of the filter plate also drives the movable plate to move back and forth. This movement of the movable plate causes the movable rod to rotate, which in turn pushes the movable plate upwards. Once upwards, the movable plate slides on the limit rod and stretches the return spring, allowing the insert rod on the movable plate to insert into the holes in the filter plate. This clears the filter plate and removes impurities. The removed impurities leave the filter plate during its left and right movement. This filtration assembly ensures that the filter plate is clear during wastewater filtration, preventing blockages in the holes and ensuring proper wastewater treatment, thus improving practicality.

[0021] 2. Impurities can be discharged through the drain pipe. If the impurities are large and difficult to discharge, the movable sleeve can be pulled to slide on the rotating rod and compress the spring, allowing the positioning block to disengage from the positioning groove. Then, rotating the rotating rod will displace the mounting block from the rotating plate, allowing the rotating plate to be opened for cleaning of impurities. After cleaning, the rotating plate can be closed, and the cleaning groove can be sealed with a sealing plug. Moving the movable sleeve and rotating the rotating rod will align the positioning block with the positioning groove. Releasing the movable sleeve will cause the positioning block to engage with the positioning groove under the action of the compression spring, thus positioning the rotating plate and facilitating the cleaning of impurities inside the primary sedimentation tank, improving practicality.

[0032] Two sets of fixing blocks 217 are symmetrically installed on one side of the bottom of the filter plate 202, and two guide rods 218 are fixedly installed between the two sets of fixing blocks 217. A fixing sleeve 219 is fitted around the guide rod 218, and the fixing sleeve 219 is fixedly connected to the through groove 214 to support and limit the movement of the filter plate 202. A cleaning groove 220 is provided through one side of the primary sedimentation tank 1 above the sewage pipe 106. A rotating plate 221 is hinged to the outside of the primary sedimentation tank 1 on one side of the cleaning groove 220, and a sealing plug 222 is fixedly installed on one side of the rotating plate 221.

[0033] Working principle: Before using this type of wastewater treatment equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, a filter assembly 2 is installed inside the primary sedimentation tank 1. During wastewater filtration, the wastewater enters the primary sedimentation tank 1 through the inlet pipe 105 and is filtered by the filter plate 202. Impurities can pass through the filter plate 202 and the through channel 214 into one side of the primary sedimentation tank 1, and are subsequently discharged through the drain pipe 106. Simultaneously with wastewater filtration, the drive motor 210 is activated to rotate the cam 211. The rotation of the cam 211 pushes the mounting plate 206 to move. After the mounting plate 206 moves, it slides on the support rod 207 and stretches the telescopic spring 208. After the cam 211 rotates one revolution, the telescopic spring 208 returns to its original shape, allowing the mounting plate 206 to reset. The mounting plate 206 then drives the filter plate 202 to move back and forth. Simultaneously, the filter plate 202 transports the filtered impurities. The up-and-down and left-and-right movement allows for better screening of impurities, facilitating their removal from the filter plate 202. The reciprocating movement of the filter plate 202 also drives the reciprocating movement of the movable plate 203. This movement of the movable plate 203 causes the movable rod 213 to rotate, which in turn pushes the movable plate 203 upwards. After moving upwards, the movable plate 203 slides on the limiting rod 215 and stretches the return spring 216, allowing the insertion rod 204 on the movable plate 203 to insert into the holes in the filter plate 202. This clears the filter plate 202, removing impurities. These impurities then leave the filter plate 202 during its left-and-right movement. The filter assembly 2 ensures that the filter plate 202 is cleared during wastewater filtration, preventing blockages in the holes and ensuring proper wastewater treatment. This enhances the filter's practicality.

[0034] Impurities can be discharged through the drain pipe 106. If the impurities are large and difficult to discharge, the movable sleeve 225 can be pulled to slide on the rotating rod 223 and compress the compression spring 224, so that the positioning block 227 can be disengaged from the positioning groove 228. Then, the rotating rod 223 is rotated to displace the mounting block 226 from the rotating plate 221, so that the rotating plate 221 can be opened to clean the impurities. After cleaning, the rotating plate 221 can be closed, and the cleaning groove 220 is sealed by the sealing plug 222. The movable sleeve 225 is moved and the rotating rod 223 is rotated to align the positioning block 227 with the positioning groove 228. The movable sleeve 225 is released, and the positioning block 227 is engaged with the positioning groove 228 under the action of the compression spring 224, so that the rotating plate 221 is positioned, thereby facilitating the cleaning of impurities inside the primary sedimentation tank 1 and improving practicality.
