Description

  The present invention relates to a net cleaning device. More specifically, a cleaning apparatus for cleaning a net and removing deposits on the net, the cleaning apparatus being provided in one or two or more passages through which the net to be cleaned passes, and the passages The present invention relates to a net cleaning device comprising one or two or more high-pressure nozzles for injecting pressurized water into a net from a notch, wherein the passage is formed with a gradually increasing gradient from an inlet to an outlet.

  Conventionally, a glue supplier lifts a glue net installed on the sea surface (about 2 kg per sheet in the state before use, but reaches about 50 to 100 kg including glue and moisture) to the ship, In a state where the ship is covered, the paste is recovered by repeating the operation of cutting the leaf leaves with a rotor mounted on the ship 2 to 15 degrees.

  On the other hand, the size of the glue net varies slightly depending on the region, but it has a rectangular shape of about 1.6 m × 20 m and is quite large. In addition, the glue net is composed of a grid mesh, such as a rhombus, with a side of about 16 cm, for example, which is smaller than the overall size, and the glue is attached to this small grid mesh. There are also some that bite into the twists of the glue net. Therefore, even if it takes a considerable amount of time and effort to clean and remove the glue that adheres to the glue net, the glue is tightly entangled with the fiber of the glue net, so that even the glue that bites into the knot is completely removed. Since the paste cannot be removed and the paste is easily rotted, it is not in a state where it can be reused due to the generation of a strange odor or the generation of pests. For this reason, there is a problem that the glue net is not friendly to the environment because it is collected and discarded by a collection company, or dumped in the sea or in the mountains.

  For example, in a large pulsator type washing machine, there is an attempt to remove the glue adhering to the collected glue net, but the glue adhering to the glue net cannot be completely removed, and the glue once picked up in the washing machine It is difficult to drop the glue, and the net length is about 20m when the net is taken out after washing. There was a problem that there were many.

  In addition, since it takes about 30 minutes to clean the glue net with one large washing machine, there is also a problem that washing of the glue net cannot be performed in a large amount in a short time.

  Therefore, the present inventors have confirmed that the network that has been used only once is discarded after use, and that the resource is reduced, reused, reused, recycled (reduced consumption ( In light of the social needs that have been screamed (reduced, reuse, recycle, also called 3R), the adhering matter attached to the used net The technical problem is to devise a cleaning device that can be completely removed and that can clean a large amount of nets in a short time. In addition, in this invention, a net | network is a concept containing a net | network, an aquaculture net | network, and another net | network.

  Further, in order to completely remove the glue adhering to the glue net, a technical problem is to prevent the redeposition of the glue once removed from the glue net.

  In addition, it is a technical problem to reduce labor and save water used for cleaning by cleaning a large amount of nets at once.

The net cleaning apparatus of the present invention is a cleaning apparatus for cleaning a net and removing deposits on the net, and the cleaning apparatus has one or more cylindrical passages through which the net to be cleaned passes, It consists of a one or more high-pressure nozzles for jetting pressure water to the network from the notch provided in said cylindrical passage, the cutout portion, one or more of which are provided along the traveling direction of the glue network The cylindrical passage is formed of a substantially tubular member, and is characterized in that a gradient that gradually increases from the inlet to the outlet is formed in order to prevent the glue washed from the glue net from reattaching .

  Moreover, it is preferable that the two or more passages are arranged in parallel in the vertical direction.

  Moreover, it is preferable that the said high pressure nozzle injects high pressure water from the left-right direction of the said channel | path.

  The high-pressure nozzle is preferably a rotary nozzle.

Moreover, it is preferable that the water pressure of the high pressure water injected from the said high pressure nozzle is 10-150 kg / cm < ² >.

  Moreover, it is preferable to further have a glue net drawing means.

  Moreover, it is preferable that the angle of the said gradient is 3-30 degrees.

  According to the present invention, it is possible to prevent the reattachment of the glue net, to completely remove the glue adhering to the used glue net, and to wash a large quantity of the glue net at a time. It is possible to provide an environment-friendly gauze cleaning device that achieves reduction, reuse, and recycling.

  In addition, since a large amount of nets can be washed at a time, labor can be reduced and water used for washing can be saved.

  Further, since the cleaning device is provided with a gradient of 3 to 30 °, the paste after cleaning does not adhere to the net again.

  Hereinafter, a net cleaning apparatus of the present invention (hereinafter simply referred to as “cleaning apparatus”) will be described in detail with reference to the accompanying drawings.

The high-pressure water is supplied from a tank (not shown) and is jetted by a high-pressure nozzle 3 through a pipe C from a high-pressure pump P (hereinafter simply referred to as pump P).

  The removed glue is recovered by the recovery mechanism 5, and then applied to a dehydrator (not shown) for reuse. With this collection mechanism 5, after cleaning, the glue removed from the glue net can be used effectively without being discarded, and low consumption, reuse, and recycling of resources are realized. can do. The collected paste can be processed, for example, as feed or food, or as fertilizer.

  When the cleaned glue nets N1 to N3 retreat from the exit of the passage 2, they are distributed by the glue net distributing means 4 in the same manner as the inlet side, and are sent through rollers R2 and R3 which are glue net drawing means. In the present invention, the glue net pulling means is not limited to a roller, and may be human power, and includes known means capable of pulling the glue net. In FIG. 1, the roller R2 is applied with a driving force by the motor M and rotates counterclockwise, and the net in the right direction in FIG. 1 is transferred. The table on which the driven roller R3 is placed is provided with a gas damper D, which can swing vertically according to the thickness of the glue net. Note that the number of rollers is not limited to two, and the number of rollers may be three or more. Further, as the shape of the roller R2 disposed in the upper part and the shape of the roller R3 disposed in the lower part, for example, a cylindrical shape is preferably adopted, but the shape is not limited thereto. For example, a spindle shape or a bowl shape may be employed.

  Furthermore, the rollers R2 and R3 only need to be arranged so as to be in contact with each other, and are not necessarily arranged in parallel with each other (that is, they can be arranged in a twisted state with respect to each other). .

  At least one of the rollers R2 and R3 is rotated by human power (torque is generated by a crank) or power (rotational torque generated by the motor M is transmitted by a belt or a gear (not shown)). Torque can also be applied. The rotation generated by the motor M can be changed by, for example, an inverter, a reduction gear mechanism, or the like in order to adjust the traveling speed of the net.

  Further, the roller R3 disposed in the lower portion is biased by a conventionally known biasing means such as a compression coil spring (or a tension coil spring) or an air spring to press the roller R3 disposed in the lower portion. Pressure can also be applied.

  Further, the apparatus of the present invention can be made movable by known means such as forming a roller at the lower part of the apparatus main body.

  Next, the high-pressure nozzle 3 used in the present invention will be described with reference to FIGS. The glue net N passing through the passage 2 is cleaned by the high pressure water supplied from the pump P through the pipe C being jetted by the high pressure nozzle 3. The high-pressure nozzle 3 in FIG. 2 is a rotary nozzle, rotates around the axis A, and high-pressure water is injected by the injection units 31 and 32 having injection holes provided at both ends of the swivel arm 30. In FIG. 2, a total of four injection units, two at each end, are provided per high pressure nozzle, but the number of injection units is not particularly limited.

  As shown in FIG. 3, the injection units 31 and 32 are deflected in the injection direction by an angle θ (θ = 3 to 25 degrees) in opposite directions with respect to the axis X. Thus, by deflecting by the angle θ, a rotational force can be generated in the high-pressure nozzle 3, and by rotating the rotational speed 50 to 300 per minute, it is possible to inject over a wide range in the cleaning chamber. And it has the advantage that it becomes easy to drop paste.

The high-pressure nozzle 3 injects about 10 to 150 kg / cm ² of high-pressure water (more preferably, 80 to 120 kg / cm ² of high-pressure water) from the left-right direction of the passage 2 of the glue net N to wash the glue net N. . The number and position of the high-pressure nozzles 3 are not particularly limited, and the number of the high-pressure nozzles 3 can be increased / decreased as appropriate according to the desired cleaning capability. The position of the high-pressure nozzles can also be provided at a position where injection can be performed from above and below. It is also possible to provide at a position where injection can be performed from all directions of the passage 2. By providing a plurality of high-pressure nozzles 3 along the traveling direction of the glue net N, it is possible to appropriately adjust the cleaning ability.

  FIG. 4 is a diagram showing another form of the high-pressure nozzle. In the high-pressure nozzle 5, the rotating part 52 rotates around the axis A2. High pressure water is injected from the injection unit 51 provided in the rotation unit 52, and the injection unit 51 is deflected toward the circumferential direction of the rotation unit 52, and can be injected in a wider range than the outer periphery of the rotation unit 52. is there.

  Next, the passage 2 will be described with reference to FIGS. 5 (a) and 5 (b). The passage 2 is a passage through which the glue net N passes. The shape of the passage 2 is not particularly limited as long as the glue net can pass and can be washed. However, as shown in FIG. A part is notched so as to be exposed. In FIG. 5, a notch 8 is formed between the cylindrical passages 7. In the present invention, the notch portion 8 refers to a portion in which a part of the passage is notched in order to inject high-pressure water from the high-pressure nozzle onto the glue net. For example, only the injection point of the high-pressure nozzle is notched. It is a concept including the part which exists and the space | gap formed between substantially cyclic | annular members like FIG.

  The notch 8 can be provided with a holding means for holding a glue net. In FIG. 5A, a plurality of substantially annular members 6 are continuously arranged on a plane perpendicular to the direction of travel of the glue net N. Thus, the network N is held. The plurality of substantially annular members 6 are fixed to the cylindrical passage 7 by welding or heat-sealing. The fixing means is not particularly limited as long as it is a known fixing means such as screwing with a screw. There is nothing. The substantially annular member 6 and the cylindrical passage 7 are preferably made of metal or synthetic resin, but the material is not particularly limited. Further, the holding means is not limited to the shape of the substantially annular member 6 and may be a substantially rectangular shape or a substantially polygonal shape.

  When the passage 2 includes the substantially annular member 6 as shown in FIG. 5A and the cylindrical passage 7 and the substantially annular member 6 are alternately arranged, the glue net N passes through the cylindrical passage 7. Furthermore, resistance due to the knot of the net can be reduced. Further, as shown in FIG. 5 (b), the substantially annular member 6 and the cylindrical passage 7 are provided with respect to the traveling direction of the glue mesh in order to reduce the resistance to the traveling direction of the glue mesh N due to the knot of the mesh. It is chamfered and rounded.

  Moreover, when a partition plate is provided in the passage 2, there is an advantage that it is possible to prevent scattered glue from adhering to the washed net. Although a partition plate can be provided in the upper part of the channel | path 2, a lower part, between adjacent high pressure nozzles, a high pressure nozzle etc., an installation place in particular is not limited. In addition, a scattering prevention cover for preventing scattering of the glue net can be provided on the upper part of the apparatus of the present invention.

  Next, a gradient formed from the inlet side to the outlet side of the passage 2 will be described with reference to FIGS. FIG. 6A shows the cleaning device 1 itself tilted so that the outlet side of the passage 2 becomes higher, and FIG. 6B shows the gradient by tilting only the passage 2 without tilting the cleaning device 1 itself. Is formed. The method for forming the gradient is not particularly limited, and it is also possible to form the gradient only at the cleaning portion of the glue net. In this way, by providing a gradient in the passage 2, it is possible to prevent the removed glue from adhering to the glue net again. The angle of the gradient is not particularly limited, but is preferably θ = 3 to 30 °, and more preferably 4 to 6 °.

  Next, the net distribution means 4 will be described with reference to FIG. The glue network distributing means 4 is a means for guiding a plurality of glue nets N so that the glue nets N introduced into the path 2 and leaving the path 2 are not entangled. In FIG. 7, it has a ladder-like shape, and a gluing net is introduced into and exited from each opening so that the gluing net N enters and exits from a separate entrance and exit, so that the entrance side and exit of the passage There will be no tangling or entanglement of glue nets on the side. In FIG. 7, a ladder-like shape is presented, but the shape of the glue net distributing means 4 is not particularly limited.

As shown in FIG. 1 and FIG. 8, the paste was cleaned at three locations using a cleaning device 1 provided with three passages 2 in the vertical direction and three high-pressure nozzles on the left and right. ^Two high-pressure nozzles 3 (with a length of the swivel arm of 170 mm) for injecting 80 kg / cm ² of high-pressure water are provided at two locations on the inlet side, and 50 kg is provided on the outlet-side cleaning location. High pressure nozzles 5 for injecting high-pressure water of / cm ² were provided on the left and right. In the passage 2, a stainless steel cylindrical passage 7 having a diameter of 70 mm and a substantially annular member 6 having a diameter of 50 mm were alternately provided, and the length of the three cleaning portions was 250 mm. In addition, a cleaning device having a gradient at an angle of 20 ° so as to increase the outlet side was used. The size of the glue net N to be washed was 1.6 m × 20 m for one sheet, and the weight of the glue net before washing was 60 kg per sheet. The ends of this glue net were connected to each other, 10 glue nets were connected in a row, and each passage was passed through. Accordingly, since there are three passages, a total of 30 glue nets were washed. Hereinafter, the cleaning method will be described.

(1) First, a wire with a hook is passed from the outlet side of the passage 2 to the inlet side, and hooks are hooked on yarns extended from the four corners of the glue net to be cleaned. The three nets were made washable through the passage 2, the outlet side net distribution means, and the rollers R2 and R3.

(2) The motor M was driven, the roller R2 was rotated and the glue net N was advanced, and at the same time, high-pressure water from the pump P was jetted by the high-pressure nozzle 3 and the high-pressure nozzle 5. The high-pressure nozzles 3 and 5 inject high-pressure water from both the left and right sides into the glue net, so that the glue net N can be washed, and the glue net N can be prevented from protruding from the substantially annular member. Could be transferred.

(3) The nets N1 to N3 passing through the passage 2 were first subjected to rough cleaning in the first cleaning section. In the rough cleaning, when the high pressure nozzle 3 rotates, high pressure water can be sprayed onto all of the nets N1 to N3 that pass through the substantially annular member, and the glue on the surface is removed.

(4) After the rough cleaning, the intermediate cleaning was performed in the second cleaning section through the cylindrical passage. In the intermediate cleaning, as in the rough cleaning, the high-pressure nozzle 3 is rotated so that high-pressure water is sprayed on all of the nets N1 to N3 that pass through the substantially annular member 6 to remove the paste.

(5) After intermediate cleaning, rinsing was performed in the third cleaning section through the cylindrical passage 7. Rinse washing was performed by the high pressure nozzle 5 to wash the glue nets N1 to N3.

  As a result, it was possible to clean 30 glue nets in 30 minutes and 1 minute per sheet. Furthermore, most of the glue adhering to the glue net before washing remained on the glue net after washing, and the weight per piece after washing was 2.6 kg. No glue remained even at the glued line of the glue net, the glue could be completely removed, and the smell of the glue disappeared.

  Furthermore, the amount of water used was 150 L / min for the high-pressure nozzle (total of six high-pressure nozzles), and 4500 L of water was consumed to wash 30 glue nets. In washing with a washing machine, 420 L / min of water is consumed to wash a single net, and it takes 30 minutes per sheet. Therefore, 420 × 30 × 30 is required to wash 30 nets. = 378000 L of water is required. It has been found that using the apparatus of the present invention saves significant water.
