Abstract

The present invention is a technique for the removal of contaminants in the sewage treatment plant or wastewater treatment plant.

The purpose of the present invention is to remove the contaminants collected in the rake of the fine screen and to remove them out at the same time. To provide a device.

In order to achieve this purpose, near the upper drive sprocket of the washing machine, a reciprocating oscillation removal plate is installed around the main body of the dust discharge chute installed separately from the main body of the dust removal machine, and the removal plate is pulled in one direction with a spring. When the rake comes up, it moves up and touches it, moves out of the rake, scrapes and removes it, pushes it into the chute chute and drops it to the bottom, and returns it to its original position by the pulling force of the spring. Proximity switches were installed next to the plates, so that while the machine was running, an alarm would sound if the proximity switch did not operate even after one rake rake had progressed.

This design makes it easy to install and repair the device by assembling the discharge chute body, which reliably removes impurities and integrally assembles the necessary accessories separately from the main body of the vibration damper. There is an effect that can be found.

Description

Screening remover of fine bar screen

The present invention is a technique for removing the contaminants to remove the contaminants installed in the sedimentation channel of the sewage treatment plant or wastewater treatment plant.

The debris removal device is divided into the fine screen screen damper installed at the front of the settlement and the fine screen screen damper installed at the rear. There is no strict separation between the two screens. Fine wood screens with intervals of less than 2 to 10 mm are called fine wood screens.

As a device for separating and removing a contaminant from a rake extractor of a conventional fine screen screen vibrator, the end of the chuck rake is forcibly prevented from proceeding so that the rake is inclined so that the scavenger is removed and installed inside the scavenger rake to push the contaminants out The serving was typically used.

However, the device that removes the tip of the rake by forcibly obstructing the progression has a disadvantage in that the rake or lifting chain is easily broken and the device is large because it receives a lot of physical force.

The device that pushes out the contaminants by installing the rake extractor inside the vibration damper is relatively used because it pushes the contaminants with relatively small force and is positioned by gravity, but the device must be installed in the damper main body near the upper drive shaft. It was difficult to check, and it was very difficult to check or repair normally, and it was difficult to know whether it worked correctly.

The technical problem to be achieved by the present invention is to provide a dust removal device having a simple structure, excellent effect of removing impurities, easy installation, inspection and repair, and remotely knowing normal operation.

The fine bar screen 6 with fine spacing between the channel bottom (b) and the upper channel slab (c) was installed to have a tilt angle of about 75 ° at a position corresponding to the rake 5.

Install the discharge chute body 7 on the side near the drive shaft sprocket 2 of the vibration damping main body 1 so that the removed debris is discharged out of the vibration damping body. Contact the corresponding position and tighten the tightening screw (9) to install it firmly. This discharge chute body (7) is to be connected to the vibration damper body (1) after assembling all accessories to be installed here.

The discharge chute body 7 is provided with a bearing unit screw symmetrically mounted on both sides of the discharge chute body 7 with the unit bearing 14 rotated at a predetermined position outside the discharge chute body 7 at a predetermined position. Secure firmly.

The support bearing 13 was inserted into the unit bearing 14, and the support shaft 13 was inserted into the lower hole of the rocking arm 11, which has a connection hole at both ends, so as not to be pulled out.

The debris removing plate 10 is integrally formed therein and inserted into the connecting hole 10-1 formed long in the longitudinal direction to insert the connecting rod 12 inserted into the upper hole of the rocking arm 11 so as to assemble through the key. B or through bolts were fixed so as not to rotate with each other and the tip of the removal plate (10) to maintain the proper angle with the rake (5).

3 is a circuit diagram of the alarm and cutoff device of the present invention.

DC power supply uses two types of 24V and 12V, and electronic circuit uses 12V and 24V power for coil of magnetic contactor.

One terminal of the oscillator movable switch (SW ₁ ) is connected to a 24V DC power supply, the other terminal is connected to one terminal of the electromagnetic contactor coil (X ₁ ) for the oscillator, and the other terminal of the oscillator magnetic contactor coil (X ₁ ) is OV. Connected to.

One terminal of the a contact (SW ₂ ) of the electromagnetic contactor coil (X ₁ ) for the oscillator was connected to 12V and the other terminal was connected to the oscillator to serve as an operating power source of the oscillator.

The output (pulse) of the oscillator is input to the counting circuit and converted into a number to be output so that it becomes one input signal of the coefficient comparator, and the output of the separately set counter is the other input signal of the coefficient comparator. The output signal is the input signal of the transistor (Tr) amplifier.

One of the terminals (SW ₃ ) of the proximity switch 21 was connected to 12V and the other to the operating power supply of the pulse generator, and the output of the pulse generator became a reset signal and connected to the reset terminal of the counting circuit.

One side of the magnetic contactor coil (X ₂ ) for the alarm is connected to the 24V DC power supply, the other is connected to the input terminal of the amplifier (Tr), and one side of the contact (SW ₄ ) of the magnetic contactor coil (X ₂ ) for the alarm. Is connected to 24V and the other end is connected to the magnetic contactor coil (X ₃ ) for shutting off the alarm and vibration suppressor.

One side of the contact b SW ₄ of the magnetic contactor coil X ₃ for driving power interruption was connected to the driving power supply (AC power supply), and the other was connected to the magnetic contactor coil X ₄ for vibration suppressor operation.

The operation of the present invention as follows.

When the drive shaft sprocket (2) is rotated in the direction of the arrow when the drive shaft is supplied with driving power to start operation, the driven sprocket (3) connected by the lifting chain (4) also rotates at the same speed and is kept taut by both sprockets. When the rake 5 is installed at a right angle to the lifting chain 4 and the rake 5 is reached, the rake 5 is caught on the claw bar screen 6. ) Scrapes up to remove the impurities, and removes the impurities in the detail bar screen (6), and removes the contaminants that are collected in the rakes (5) and continue to come up and contact the removal plate (10). The plate 10 is pushed upward to perform an arc-shaped motion around the unit bearing 14 fixed to the outside of the discharge chute body 7 so that the debris removing plate 10 is applied to the debris rake 5. Because it moves from the inside to the outside in contact with the foreign matter accumulated in the rake (5) is pushed out and removed through the discharge chute and stored in the bottom of the trap (not shown).

As the junk extractor (5) continues to move upwards, the junk extractor (5) continues to be pushed out to the outside of the junk extractor (5), and the junk extractor (5) is driven by gravity and tension spring (17). When the next junk rake (5) is moved to the first position again to remove the junk while continuing the above action, and the rocking arm (11) has a high speed when moving to the original position, but this is a good cushioning support ( The shock is absorbed during contact with 19), and no mechanical force is generated.

If the debris removal plate 10 or related accessories are damaged during use, simply loosen the tightening screw 9 on the connection flange 8 of the discharge chute body 8 to remove the discharge chute body 7 assembly from the vibration damper body 1. Can be removed and repaired at a convenient location, making the work very easy.When reassembling, the connection flange (8) can be tightened with the tightening screw (9) against the vibration damper body (1). Very easy.

As shown in FIG. 3, when the micro-vibrator operation switch SW ₁ is started to operate the machine, at the same time, the contact a of the contactor SW ₂ of the electromagnetic contactor enters through the current through the electromagnetic contactor coil X1 for the oscillator. In contact with the power supply to the oscillator, the oscillator oscillates at a certain frequency. This frequency is input to the counting circuit.

In the coefficient setter, the time required for the dust extractor rake (5) of the vibration damper to be moved by one unit is set slightly larger than the number corresponding to the frequency of the oscillator during that time, and connected to the other input side of the coefficient comparator. If the number from the counter circuit is larger than that, the output of the counter comparator is set to 1 (high voltage), and if it is smaller, the output is set to 0, and the dust extractor 5 is moved so that the dust removing plate 10 moves upward. If it is pushed, the swing arm 11 connected to it is pushed backward. If it is pushed to the end, the a contact (SW ₃ ) of the proximity switch 21 is contacted and outputs one narrow pulse, which is the reset terminal of the counter circuit. When the pulse signal comes in, the number counted in the counting circuit becomes 0 and counting starts again.

However, since the counting circuit is to count the oscillation frequency between the time that the proximity switch 21 operates once again and operates again, when the fine rake 5 normally operates, the swing arm 11 and the proximity switch 21 operate. As the counting circuit is reset and counted again every cycle, the count during this time is always slightly smaller than the number set by the count setter, and the output of the count comparator is always zero.

However, if the dust extractor 5 cannot move due to any cause, the oscillation arm 11 does not move and the proximity switch 21 does not work, so the counting circuit cannot be reset. As a result, it becomes larger than the number set in the coefficient setter, and the output to the coefficient comparator becomes 1 so that the voltage is applied to the amplifier Tr, and a current is applied to the magnetic contactor coil (X ₂ ) for the alarm. ₄ ) When the alarm comes on and power is supplied to the alarm, the alarm operates and you can know the abnormality of the vibration suppressor.

At the same time, a current flows through the magnetic contactor coil (X ₃ ) for shutting off the vibration suppressor, and the contact b (SW ₅ ) of the magnetic contactor is operated to cut off the circuit to supply the operating power to the magnetic contactor coil (X ₄ ) for operating the vibration suppressor. The operation of the damper is automatically stopped by shutting off.

The apparatus for removing fine wood contaminants of the present invention is a device for removing contaminants collected on the rakes, which is integrally assembled to the discharge chute body, which can be assembled into the vibration isolator body after being manufactured as a unit assembly separately from the vibration isolator body. Easy and simple structure can effectively remove impurities, and it is easy to maintain and repair because it can check the machine operation condition from the outside or distant place (for example, monitoring room).
