For example, a stiffing box 116 may be secured to the housing by means of brackets BR by means of fasteners such as bolts and nuts BO. If desired, the drive module 11 may itself have a suitable packing device.

The pump module 12 is a device that is operated by the drive module 11 and allows air to be discharged through the discharge module 13 into the water. The pump module 12 includes an impeller 121 connected to the rotating shaft 117, a connecting shaft 122 connected to the rotating shaft 117, a connecting shaft 122 for closing the connecting portion between the connecting shaft 122 and the case of the impeller 121 And an oil seal 123 and a bearing 124 installed at a connection portion between the rotation shaft 117 of the motor and the oil seal 123. The impeller 121 may have any structure including a plurality of rotating blades, and the present invention is not limited by the structure of the impeller 121.

A stand 14 having an appropriate structure may be provided below the jetter 10 and a cover may be installed on the upper side of the stand 14 to fix the driving module 11 and the pump module 12.

Since the jet leter 10 must be installed inside the processing apparatus, it is necessary to have the elevating means. For example, the fixing ring 115a may be provided on the upper side of the jet lighter 10 and the jet lighter 10 may be installed in the water by the hook 115 coupled to the fixing ring 115a, have. Various lifting means may be provided in the jet lighter 10 and the present invention is not limited to the embodiments shown.

The pump module 12 may be connected to a discharge module 13 for discharging air into the water. The air introduced into the discharge module 13 by the propulsion force of the impeller 121 installed in the pump module 12 flows through the injection unit 131, the guide tube 132, the control tube 133 and the nozzle 134 . The air may be supplied through the pump module 12 without being limited thereto, though it may be supplied through the appropriate position of the exhaust module 13. The injection unit 131 may have a suitable structure for guiding the traveling direction of the air and may be conical in shape, for example, a diameter of which is narrowed.

The guide tube 132 or the adjustment tube 133 may have a suitable structure for adjusting the air flow and further a vortex forming steel wire for forming a vortex may be formed inside the guide tube 132 or the adjustment tube 133 .

Control of airflow includes such things as air velocity, pressure, or exhaust velocity, and vortex formation refers to the progressive air being made into a vortex shape. The adjustment of the air progression determines the distance that the air can escape from the drain module 13 in the water and proceed in the straight forward direction.

The structure of the discharge module 13 for controlling the air flow or forming the eddy current is described below.

Fig. 2 shows an embodiment of a discharge module 13 which can be applied to the jet lighter of Fig.

2, the discharge module 13 includes a connection tube 131a connected to the injection unit 131, a guide tube 132 extending from one end of the connection tube 131a, A control tube 133 extending from the end and a nozzle 134 formed at one end of the control tube 133. The connecting tube 131a, the guide tube 132 and the regulating tube 133 may have a hollow cylindrical shape and the nozzle 134 may have any shape known in the art in which a plurality of through- Lt; / RTI >

The connection tube 131a and the adjustment tube 133 may extend with a certain diameter and the adjustment tube 133 may have a larger diameter than the connection tube 131a. The guide tube 132 may have a different diameter along the longitudinal direction and may be formed to connect the connection tube 131a and the adjustment tube 133. [

The connecting tubes 131a are formed to have different lengths and the adjusting tubes 133 and the guide tubes 132 are appropriately adjusted according to the length of the connecting tubes 131a as shown in the upper side and the lower side of Fig. . Specifically, if the air to be discharged needs to be moved far from the water, the connection tube 131a may be formed long. For example, when a sufficient number of jet lecturers are installed in the processing apparatus, the air can be shortened in travel path. On the other hand, when a small number of jet lecturers are installed in the treatment apparatus to circulate water in the treatment apparatus, it is advantageous that the connection tube 131a is formed long.

The guide tube 132 is provided with a function of preventing a sudden change in pressure or a change in velocity in the traveling direction of the air so that the adjustment tube 133 has a constant diameter in the longitudinal direction, Lt; / RTI >

The inclination angle of the guide tube 132 may be, for example, 3 to 15 degrees, but is not limited thereto. The length D2 of the guide tube 132 may be set to have the suggested inclination angle. On the other hand, the diameter ratio of the connecting tube 131a and the adjusting tube 133 may be the diameter of the connecting tube 131a: the diameter of the adjusting tube 133 = 1: 1.5 to 2.5. The length D3 of the connecting tube 131a: the length D1 of the adjusting tube 133 = 100: 20 to 80, but is not limited thereto.

If the inclination angle of the guide tube 132 is 3 to 6 degrees, D3: D1 = 100: 50 to 70 can be obtained. If the inclination angle of the guide tube 132 is 6 to 15 degrees, D3: D1 = 100: 20 to 30. As described above, the ratio of D3 to D1 according to the inclination angle of the guide tube 132 ensures that the discharge air is linearly moved, while at the same time, the circulation type and mixing level of the water in the treatment apparatus can be increased. A length ratio having various structures can be set and the present invention is not limited to the embodiments shown.

Figure 3 illustrates an embodiment of an interior of the discharge module and a vortex forming structure that may be applied to the jettor of Figure 2;

3 (a) and 3 (b), the discharge module 13 can be composed of the outer rim 31 and the discharge passage 33, and the vortex forming steel wire 32 can be formed on the surface of the discharge passage 33, Can be arranged. The vortex-forming steel wire 32 is for allowing the air to advance while being rotated, for example, in the form of a spiral or a helix. The vortex forming steel wire 32 may be, for example, a two to ten wire steel wire structure. The steel wire can be formed in a structure protruding from the inner surface of the discharge passage and the number of steel wires can be appropriately adjusted according to the discharge length. For example, the longer the discharge length, the smaller the number of steel wires. The vortex forming steel wire 32 may be formed on all or part of the regulating tube, formed on the regulating tube and guide tube, or formed on the entire exhausting module 13. 3 (a) and 3 (b) show the three-piece steel wire and the six-wire steel wire, respectively.

The vortex-forming steel wire can have various structures and can be made, for example, as shown in Fig. 3 (c). Referring to FIG. 3 (C), the vortex-forming steel wire may be formed by an elongated protrusion 34 extending along the surface in a spiral shape with a constant width. The extension protrusion 34 may have a width that is 2 to 20 times larger than the height 34a and the vortex formation steel wire 32 may be formed by the spiral extension groove formed between the extension protrusions 34 have. The width of the extending projection 34 and the vortex forming steel wire 32 can be appropriately adjusted in accordance with the number of steel wires. However, it is preferable that the width of the extending projection 34 is 1/200 to 1/5 of the extending length. If the width of the extension protrusion 34 is smaller than the suggested value, eddy current is hardly formed, and when the width is larger than the suggested value, the linear motion of the air is weakened. On the other hand, the extending projections 34 may extend in different widths depending on the traveling direction depending on the inner diameter.

The extending projections 34 may be formed in a shape having a small cross-sectional area in a direction in which the projecting projections 34 are projected. However, it is preferable that the protruding height be 1/100 to 1/5 of the whole diameter. It is difficult to form the vortex when the value is smaller than the suggested value, and the amount of bubbles increases when the value is larger than the presented value.

Extending grooves 32 or extending projections 34 of various structures can be formed and the present invention is not limited to the embodiments shown.

The reaction tank 40 may have a rectangular cross section or a circular cross section, for example, and the jet leters 10a, 10b, 10c, and 10d may be arranged clockwise or counterclockwise along the circumference. The air discharge direction A of the jet leters 10a, 10b, 10c can be set based on, for example, an angle with which the peripheral wall surface collides. For example, the air discharge direction A is set based on an angle of incidence on the wall surface of the reaction tank 40. For example, if it is necessary to maintain a high temperature in the reaction tank 40, . As described above. The speed or pressure hitting by adjusting the length of the discharge module or the length of the diameter adjusting portion can be adjusted. As used herein, the diameter adjustment portion refers to the adjustment of the length of the adjustment tube or the guide tube, or the adjustment of the length of the adjustment tube relative to the connection tube. On the other hand, the length adjusting part means adjusting the length of the guide tube.

Adjustment of the pressure or speed and adjustment of the angle with respect to the wall surface of the reaction tank 40 enables adjustment of the degree of formation of the vortex B while allowing temperature control inside the reaction tank 40. Thus, the vortex B can be controlled by the air discharge direction A and the vortex forming steel wire.

Each jettor 10a, 10b, 10c, 10d may be connected to an air supply conduit connected to the blower 41. [ As described above, the feed supply conduit may be connected to the exhaust module.
