Description

[0001] Apparatus for washing sediment sand [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a needle cleaner, and more particularly, to a needle cleaner that cleans a needle cylinder of a needle at a sewage treatment plant and the like.

Generally, in the water treatment at the sewage treatment plant, the sewage is sent to the settlement site to deposit the sand and dirt, and the sewage is sent to the settlement site. However, since the sediment deposited on the gypsum is mixed with contaminants and various pollutants, it is strictly regulated by the law because of the natural environment pollution and the like. Accordingly, the sediment mixture that has been salvaged by the needle-like sheep is sent to the needle washing apparatus, washed, and then taken out.

On the other hand, in the case of an air floating type of needle spinner, the organic matter having a low specific gravity rises together with the air bubbles, and the sand having a high specific gravity and other contaminants are precipitated.

However, the air flotation type desiccant cleaning apparatus is disadvantageous in that the efficiency of desorbing organic matters due to air floating is low, it is impossible to float an organic material mass or foreign matter having a high specific gravity, and the final organic nitrate content and water content are high.

Disclosure of Invention Technical Problem [8] The present invention has been made in view of the above problems, and an object of the present invention is to provide a needle washing apparatus capable of reducing the organic matter content and moisture content of the needle ash and improving the recovery rate of the needle.

To achieve the above object, according to the present invention, there is provided a needle washing apparatus comprising a support, a rotation passage, a mixture for supplying a silk mixture, a washing water supply unit, a rotary rotation driving unit, and a needle exit. A spinneret is formed in a cylindrical shape having a hollow shape and has one end portion higher than the other end portion so as to be rotatably supported on a supporting table in a tilted state and a needle thread outlet for discharging the needle thread is formed at one end portion, And a screw type protrusion extending from one end portion to the other end portion in a spiral direction is formed on the inner circumferential surface. The spinneret feeder feeds the spinneret through the spinneret outlet into the spinneret. The rinse water supply unit supplies the rinse water into the spinneret through the needle outlet. The rotary drive rotates the spinneret to transfer the cleaned needle in the spinneret to the needle outlet. The unloading unit removes the unloading thread discharged through the unloading outlet.

According to the present invention, it is possible to increase the effect of desorbing organic materials and contaminants having low specific gravity from the precipitation mixture, and to separate the contaminants with high specific gravity easily by separating the sediment and the grain. Therefore, the organic matter content and water content of the final discharged settling can be lowered, thereby increasing the recovery rate of the settling.

Fig. 2 is a perspective view showing a state in which the rotor is disassembled in Fig. 1; Fig. Figure 3 is a front view of Figure 1; Fig. 4 is a view for explaining the process of washing the silk mixture in Fig. 1; FIG. 5 is a schematic view for explaining the process of sorting the sediment mixture in FIG.

1 to 5, the needle cleaner 100 includes a support 110, a spinneret 120, a spinneret mixture supply unit 130, a cleaning water supply unit 140, a rotary rotation drive unit 150, and a needle take-off unit 160.

The support base 110 supports the rotary 120, the siliceous mixture supply unit 130, the cleaning water supply unit 140, the rotary rotation drive unit 150, and the silk carry-out unit 160.

The rotor 120 is formed in a cylindrical shape having a hollow shape. The rotator 120 is rotatably supported on the support table 110 in a tilted state with one end positioned higher than the other end. The swirling tube 120 has a needle thread outlet 121 for discharging the needle thread at one end and a contaminant outlet 122 for discharging the contaminant at the other end.

For example, the rotator 120 may be rotatably supported by driving rollers 152 and driven rollers 154 of a rotary rotation driving unit 150 to be described later, and may be rotatably supported by a stopper mechanism 116 in the longitudinal direction So as not to slip down. Here, the drive rollers 152 and driven rollers 154 are rotatably mounted on the support 110 via a drive shaft 153 and a driven shaft 155. [

The stopper mechanism 116 may include a stopper ring 117 and a guide roller 118. The stopper ring 117 is mounted on the outer circumferential surface of the rotator 120. The stopper ring 117 may be fixed to the rotating body 120 through a portion extending from the periphery of the center hole to surround the outer circumferential surface of the rotating body 120.

The guide roller 118 is disposed below the stopper ring 117 and closer to the impurity outlet 122 than the stopper ring 117. The guide roller 118 is mounted on the support table 110 so as to be rotatable about an axis orthogonal to the rotation direction of the rotator 120. When the stopper ring 117 rotates together with the rotator 120, the guide roller 118 can rotate with its rolling surface abutted against the stopper ring 117. [ Therefore, the rotary shaft 120 can smoothly rotate without slipping down in the longitudinal direction.

The rotor 120 has a screw-shaped projection 123 extending from one end to the other end in a spiral direction on the inner peripheral surface. The inner circumferential surface of the rotor 120 has a screw groove between the screw-shaped protrusions 123. The screw-shaped protrusion 123 may have a right triangular cross section. Here, the screw-shaped protrusion 123 has an oblique surface with respect to the inner circumferential surface of the turntable 120 and a portion facing the obturator outlet 122 is perpendicular to the inner circumferential surface of the turntable 120 Respectively.

The slurry mixture in the spinneret 120 is gradually transferred toward the needle outlet 121 in response to the spiral rotation of the screw-shaped protrusion 123, and strikes the screw-shaped protrusion 123, whereby the particle size can be sorted through this process. Therefore, the high specific gravity and the coarse grains are separated from the sediment mixture, and most of the sediment can be transferred to the sediment discharge port 121 and discharged.

The needle outlet 121 may be formed to have the same size as the hollow size of the tubular member 120 at one end of the tubular member 120. The spinneret 120 may include a needle thread discharge guide 124 that is inclined to gradually increase in diameter from the periphery of the needle thread outlet 121 to the outside. The lower portion of the needle thread guide 124 is always downwardly inclined even when the rotator 120 rotates. Therefore, the needle thread transferred to the needle thread outlet 121 can be smoothly discharged along the lower side inclined portion of the needle thread guide 124.

The contaminant discharge port 122 may be formed at a center of the other end of the rotator 120 and opened to a size smaller than the hollow size of the rotator 120. Therefore, among the silt mixture in the spinneret 120, the high specific weight silt is precipitated lower than the impurity outlet 122 and is not discharged through the impurity outlet 122, and the organic matter or impurities having a specific gravity lower than that of the clathrate outlet 122, May be floated by the water in the sump 120 and discharged through the sludge outlet 122 roll.

The rotator 120 may include a contaminant discharge pipe 125 extending outwardly from the periphery of the contaminant discharge port 122. For example, the other end of the rotator 120 is formed to be open to the same size as the hollow size of the rotator 120, and this opening can be covered by the cover plate 126. [ Here, the cover plate 126 is formed with a hole having the same diameter as the inner diameter of the obstacle discharge pipe 125 at the center, and a discharge pipe 125 can be connected to the periphery of the hole.

The slurry mixture supply part 130 supplies the slurry mixture into the spinneret 120 through the slurry outlet 121. For example, the slurry mixture supply unit 130 may include a supply pipe 131. The supply pipe 131 is disposed in parallel with the longitudinal direction of the rotator 120 and is supported on the support 110 while being partially inserted into the center of the rotator 120.

Both ends of the supply pipe 131 are closed. The supply pipe 131 has a plurality of discharge holes 131a on the lower side of the end inserted into the rotor 120. The supply pipe 131 is equipped with a connection pipe 132 connected to a supply source of the siliceous mixture (not shown) on the upper side of the end drawn out from the rotary 120. The supply pipe 131 is disposed lower than the end of the supply pipe 131 that is inserted into the pipe 120 and is lower than the end of the pipe 120 that is connected to the pipe 120. Therefore, So that they can be ejected smoothly.

The rinse water supply unit 140 supplies the rinse water into the rotator 120 through the needle outlet 121. For example, the cleaning water supply unit 140 may include a nozzle pipe 141, and nozzles 142. The nozzle pipe 141 is arranged side by side in the supply pipe 131 and is supported on the support 110 in a state partially inserted into the center of the rotator 120. The nozzle pipe 141 receives the washing water from a washing water supply source (not shown).

The nozzles 142 may be mounted at intervals in the longitudinal direction on the portion of the nozzle pipe 141 inserted in the turning tube 120. The nozzles 142 inject the washing water supplied from the nozzle pipe 141 into the rotator 120. The cleansing water injected from the nozzles 142 acts to float organic matter, impurities and the like having low specific gravity by destroying the organic material mass contained in the siliceous mixture in the spinneret 120.

The rotary rotation drive unit 150 rotates the rotator 120 to transfer the cleaned needle into the needle outlet 121 in the rotary 120. [ When the screw-shaped protrusion 123 is wound in the left screw direction from the impurity outlet 122 to the needle outlet 121, the rotary drive unit 150 rotates the rotor 120 counterclockwise, 120 can be transferred to the needle outlet 121 side. If the screw-shaped protrusion 123 is wound in the right-hand screw direction, the rotary-rotation driving unit 150 can rotate the rotary 120 in the clockwise direction.

For example, the rotary rotation drive unit 150 may include a rotation motor 151, drive rollers 152, driven rollers 154, and rotation transmission means 156. The rotation motor 151 is supported by the support base 110 so that the rotation direction of the drive shaft is the same as the rotation direction of the rotation axis 120.

The driving rollers 152 are arranged in a pair so as to be rotatable in the same direction as the rotation direction of the trolley 120. The drive rollers 152 are arranged in the longitudinal direction of the rotator 120 and are coaxially fixed to the drive shaft 153. The drive shaft 153 is rotatably supported by the support base 110. The driving rollers 152 are arranged such that each rolling surface is in contact with the lower outer peripheral surface of the rotator 120. Thus, the driving rollers 152 are enabled to rotate the rotary 120 when the rotary driving is performed.

The driven rollers 154 are paired and arranged rotatably in the same direction as the rotating direction. The driven rollers 154 are disposed at intervals in the radial direction between the driving rollers 152 and the rotator 120. The driven rollers 154 are arranged in the longitudinal direction of the rotator 120 and coaxially fixed to the driven shaft 155. The driven shaft 155 is rotatably supported on the support 110. The driven rollers (154) are arranged so that each rolling surface abuts the lower outer peripheral surface of the rotator (120). The follower rollers 154 are rotatable when the rotator 120 rotates, and rotatably support the rotator 120 as the rotator rotates.

The rotation transmitting means 156 may include a driving sprocket 156a, a driven sprocket 156b, and a chain 156c. The drive sprocket 156a is coaxially fixed to the drive shaft of the rotation motor 151 and rotated by the rotation motor 151. [ The driven sprocket 156b is coaxially fixed to the drive shaft 156a. The chain 156c spans the drive sprocket 156a and the driven sprocket 156b to transmit the rotation of the drive sprocket 156a to the driven sprocket 156b. As another example, although not shown, the rotation transmitting means may be configured to include a drive pulley, a driven pulley, and a belt.

The needle thread take-off unit 160 takes out the needle thread discharged through the needle thread outlet 121 to the outside. For example, the needle thread take-out unit 160 may include a needle pick-up member 161 and an take-out tube 162. The needle receiving member 161 may have an arc-shaped passage and may have an upward curved shape. The needle receiving member (161) has an inner diameter larger than the outer diameter of the rotator (120). The turntable receiving member 161 is mounted on the supporting table 110 so as to partially insert the lower side portion of the turntable discharging guide 124 at a distance in the radial direction of the turntable 120. [ The needle bed receiving member 161 has a discharge hole 161a formed in the center bottom surface thereof. The needle receiving member 161 receives the needle thread discharged from the needle thread discharging guide 124 and discharges the needle thread through the discharging hole 161a.

The take-out pipe 162 receives the needle thread from the pick-up member 161 and takes it out. The take-out pipe 162 may have a rectangular passageway and may have an upper portion and a lower portion. One end of the take-out pipe (162) is connected to the discharge hole (161a) of the pick and place receiving member (161). The take-out pipe 162 moves the needle thread supplied through the opening at one end from the needle receiving member 161 along the passage, and then takes it out through the opening at the other end. The take-out pipe 162 may be disposed on the lower side of the rotator 120 in parallel with the longitudinal direction of the rotator 120 and supported on the support 110. Since the take-out tube 162 is disposed in an inclined manner like the rotating body 120, the needle thread supplied into the take-out tube 162 can be smoothly moved along the path of the take-out tube 162 and can be taken out.

6, the support table 110 can be vertically pivotally mounted on the pedestal 101 so that the inclination angle of the rotator 120 can be adjusted. The inclination angle adjuster 170 adjusts the inclination angle of the rotator 120 by pivoting the support table 110 in the vertical direction. Therefore, the inclination angle of the spinneret 120 is controlled according to the specific gravity and particle size of the needle thread, the impurities, and the like contained in the silk mixture, so that the grain size can be effectively sorted.

For example, the tilt angle adjuster 170 may include a cylinder. The cylinder is structured such that the cylinder rod 171 is operated to pivot with respect to the cylinder body 172 by pneumatic or hydraulic pressure. The cylinder body 172 is hinged to the pedestal 101 and the cylinder rod 171 is hinged to the pedestal 110 so that the pedestal 110 can be pivoted as the cylinder rod 171 is stretched and contracted .

An example of the operation of the above-described needle cleaner 100 will be described below.

The rotating body 120 is rotated by the rotating rotational driving unit 150 and the washing water is supplied from the spinning bath 120 to the rotating body 120 while the washing water is supplied from the washing water supplying unit 140 to the rotating body 120, The mixture is supplied. Then, the washing water supplied into the spinneret 120 destroys the organic material mass contained in the spinneret 120 in the spinneret 120. Organic matter and impurities with low specific gravity are suspended by the water of the washing water and the siliceous mixture and discharged through the contaminant outlet 122 together with the washing water flowing into the contaminant outlet 122 and the water of the silk mixture.

In addition, the siliceous mixture in the spinneret 120 is gradually transferred toward the spinneret outlet 121 in accordance with the spiral rotation of the spinneret 123, and strikes the screw-shaped protrusion 123. In this process, The sediments and coarse particles are separated and the granules are selected. Most of the needle thread is transferred to the needle thread outlet by the spiral rotation of the screw-like projection 123, and then is taken out through the needle thread take- Coarse contaminants and the like move toward the contaminant outlet port 122 together with the washing water flowing into the contaminant outlet port 122 and the water of the silent mixture and then floated by the centrifugal force of the rotary tub 120 and discharged through the contaminant outlet port 122 .

As described above, the cleansing treatment of the cleansing mixture can increase the effect of desorbing the organic substances and the impurities having low specific gravity from the cleansing mixture, and can easily separate and discharge the contaminants with high specific gravity. As a result, it is possible to reduce the organic matter content and water content of the final discharged silt, thereby increasing the recovery rate of the silt.

It will be possible. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
