Description

Washing device for filter cross of belt press type spin dryer}

The present invention relates to a filter cloth cleaning device of a belt press type dehydrator that dewateres sludge generated during wastewater purification treatment and removes water in the sludge. By installing nozzles, the washing water spray nozzles can cross each other to clean the remaining sludge from the filter cloth.

In general, when domestic sewage or industrial wastewater is generated, the generated wastewater is collected by a water treatment plant to purify various harmful substances contained in the wastewater.

When the wastewater is treated as described above, a large amount of sludge is generated. When the sludge is treated, it is important to remove water contained in the sludge.

In order to remove water in the sludge, the sludge is first introduced into the sludge stirring tank together with the polymer flocculant and reacted to form a floc suitable for dehydration. Then, the sludge is uniformly distributed on the sludge transporting lower filter cloth through the dewatering chute. Transfer.

The upper filter cloth is covered on the upper sludge in the process of being placed on the lower filter cloth as described above and the sludge is moisturized in the sludge as the sludge is passed between the lower filter cloth and the upper filter cloth in the state of being located between the lower filter cloth and the upper filter cloth. It will become dehydrated.

The sludge dehydrated from the dehydration part is discharged to the outside of the dehydrator, and the sludge from which the water is removed is incinerated.

In the process of dewatering the sludge as described above, the sludge of the small particles remain in the upper, lower filter cloth, in order to remove this, the washing apparatus is installed on the upper, lower filter cloth transport path.

As described above, the washing apparatus installed on the transport path of the upper and lower filtration cloths has already been conceived in various forms.

For example, a typical washing apparatus is one of which is blocked and the other is connected to the hose to supply the washing water pumped from the water water pump, and a plurality of spray nozzles for spraying the washing water pumped from the water pump to the filter cloth There is a tubular washing device installed side by side.

The washing apparatus as described above requires a high pressure water water pump due to the large number of spray nozzles, and has a disadvantage in that the spray pressure is lowered because the washing water is ejected and discharged through a plurality of spray nozzles, and a large amount of expensive spray nozzles is used. The manufacturing cost increases, and there is a problem that the cleaning efficiency is inferior to the nozzle and the nozzle because the spraying amount of the washing water is small and the spray pressure is weak. It has the disadvantage of generating a lot of injection noise.

In addition, the excessive use of the wash water has a problem that adds an overload to the aeration tank or load tank.

In order to solve the shortcomings of the washing device, a washing device for washing the filter cloth by moving the washing water spray nozzle to the right and left in the orthogonal direction of the filter cloth is filed with Utility Model Registration No. 97-4134, and registered as a utility model. It was registered as No. 155512.

The washing apparatus registered in Utility Model Registration No. 155512 employs two methods of moving the washing water spray nozzle to the operation of a pneumatic cylinder and moving by a screw rod rotated by a motor.

The nozzle movement method is improved compared to using a plurality of nozzles, but the method of moving the nozzle by the pneumatic cylinder, firstly, because the cylinder is expensive, there is a problem that the manufacturing cost of the washing apparatus increases. Rather, there is a manufacturing difficulty in installing an auxiliary device for controlling the operation of the cylinder; Secondly, there is a disadvantage in that the operating cost is increased because of the large amount of electrical energy required to operate the cylinder; Third, because one spray nozzle is used to clean the filter cloth while reciprocating, the nozzle must be moved at a high speed. Therefore, the fatigue phenomenon of the cylinder is promoted, and a separate brush can be used for stable cleaning. Has no drawbacks.

In addition, the injection nozzle movement method using a screw rod has the disadvantages of using a pneumatic cylinder, as well as a problem in that a large capacity motor must be used to rotate a pair of screw rods in which the injection nozzle is moved.

In addition, since the nozzle is moved to the left and right by forward and reverse rotation of the motor, the wear phenomenon of the gear is promoted by the torque phenomenon generated during the forward and reverse rotation, and it is difficult to achieve accurate reciprocation movement due to the wear of the gear. In addition, it has a disadvantage of using a limit switch to detect the left and right movement distance of the nozzle so that the motor can be rotated forward and backward.

The present invention devised in order to solve the problems of the conventional cleaning device as described above is a connector that is guided in the slot hole of the guide plate to a pair of chain or timing belt rotated in one direction by the drive motor to each guide plate having each injection nozzle The pins are fixed to each other so that the jet nozzles can be cleaned while crossing each other according to the rotation of the chain or timing belt. First, the jet nozzle can be moved by using a small drive motor. Minimize the amount of electrical energy required to do so; Second, the spray nozzles are separated by a predetermined distance with respect to the transport direction of the filter cloth, and the washing efficiency of the filter cloth can be improved because the filter cloth is washed while crossing each other; Third, it is not necessary to use a brush as in the prior art to prevent friction wear of the filter cloth by the brush can extend the service life of the filter cloth; Fourth, the filter cloth cleaning device of the belt press type dehydrator can detect the cleaning state of the filter cloth with the sensor to automatically adjust the moving speed of the water spray nozzle and the pumping pressure and flow rate of the water pump. The purpose is to provide.

The above object of the present invention, in the belt press type dehydrator cleaning device, an I-beam having a length corresponding to the width of the filter cloth in the direction orthogonal to the filter cloth in the shower box of the dehydrator is installed, this I- A pair of hexagonal bars are installed side by side with a certain distance outside the upper and lower plates of the beam, and sprockets are wound on both ends of the shaft installed at the left and right ends of the vertical plate in the center, and the sprockets are wound around the shaft. A fixed support member having a sub sprocket connected to the sprocket of the motor and attached thereto; It has a roller that is guided along each hexagon bar installed up and down side by side of the I-beam, up and down, the slot hole for guiding the idler of the connector pinned to the chain is formed in the direction perpendicular to the center The nut-joining U-shaped banding ring includes: a guide plate having a washing water spray nozzle for spraying washing water pumped from the water pump; It is installed on the support rod installed on the guide plate in the direction of the filter cloth and detects the surface of the filter cloth washed by the washing water and if it is muddy than the transparency of the filter cloth set in the controller, it senses this to increase the moving speed of the washing water spray nozzle and increases the speed of the water pump. A sensor for increasing the washing water pumping pressure and flow rate; It is achieved by being composed of a drive motor having a sprocket chained with a subsprocket of a shaft mounted on a longitudinal plate of a fixed support member.

The guide plate having the washing water spray nozzle is spaced apart by a predetermined distance from the front and rear chains with respect to the conveying direction of the upper and lower fossils, and the connector of the guide plate is installed to one side of the upper chain, and the connector of the guide plate is the lower side of the chain. It is installed on the other side and is achieved by spraying the washing water while the spray nozzles cross each other.
