AI Technical Summary
The existing skimmer cannot effectively deal with the floating garbage behind the skimmer pipe, resulting in a dead zone for processing and causing garbage accumulation.
By adding an SLC off stroke switch to the motor's transmission assembly control circuit, the reverse operation of the screw is achieved, and the first and second extended sections are added to the screw, expanding the range of movement of the scallop pipe so that it can be reversed Spin to collect garbage in the dead zone.
The reverse rotation movement of the skimming pipe is realized, which can effectively collect garbage in the dead zone, reduce garbage accumulation, improve the cleanliness of the pool, and reduce water pollution and manual cleaning costs.

Abstract
Description
Technical Field
[0001] The utility model relates to sewage treatment equipment, and more specifically to a slag skimmer used in a secondary sedimentation tank. Background Art
[0002] The skimmer is a garbage disposal device installed on the water surface. The device mainly uses a skimmer pipe, such as Figure 1 As shown, the skimmer includes main components such as a motor 1, a reduction gear set, a screw 2, and a skimmer pipe 3. The skimmer pipe 3 is a pipe that spans the entire pool and is flush with the water body. A horizontal opening 4 is opened on the skimmer pipe 3 to form a skimmer bucket. When the skimmer pipe 3 rotates, the horizontal opening 4 is lower than the surface of the water body to collect floating objects.
[0003] The existing skimming pipe 3 relies on the forward and reverse rotation of the motor 1 to drive the screw rod 2 to move up and down, so as to adjust the opening angle of the skimming pipe 3.
[0004] like Figure 2 As shown, in the transmission component control circuit of the motor 1, the SLO travel switch and the SLC travel switch (in the virtual frame) can only perform the start and stop control of the motor 1 and the working stroke protection of the skimming pipe 3 in the area of 0° to 60°, and can only perform forward skimming, and cannot process the floating garbage behind the skimming pipe 3, thus forming a processing dead zone and causing garbage accumulation. Utility Model Content
[0005] In view of the defects existing in the prior art, the purpose of the utility model is to provide a skimmer for a secondary sedimentation tank, which can process floating garbage in the skimming dead zone by improving the skimmer pipe.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A skimmer for a secondary sedimentation tank comprises a motor, a screw rod and a skimmer pipe:
[0008] An SLC travel switch is provided in the transmission assembly control circuit of the motor to replace the original 0° stop position and realize the reverse operation of the screw rod;
[0009] The screw rod is provided with a first extension section;
[0010] The rear end of the screw rod is connected to the output side of the motor, and the front end is connected to the skimming pipe through a connecting ear plate;
[0011] The connecting ear plate is provided with a second extension section.
[0012] Preferably, the length of the first extension section is 200±1 mm.
[0013] Preferably, the length of the second extension section is 50±0.5 mm.
[0014] Preferably, the SLC open travel switch in the transmission assembly control circuit of the motor is set to a -60° stop position.
[0015] The utility model provides a skimmer for a secondary sedimentation tank, which utilizes the original equipment for transformation and upgrading, with low transformation cost and quick effect. After the transformation, the floating garbage behind the skimmer pipe can be greatly reduced, the cleanliness of the tank can be increased, water pollution can be reduced, and the cost of manual cleaning can be reduced.
