Description

[0001] Spraying Apparatus [0002]

The present invention relates to an injector capable of injecting a solution in a fan shape. More specifically, in a solution injecting apparatus installed on a road or a structure for installation, cleaning, cooling, landscaping, or the like, mounted on a vehicle or the like, a spray capable of spraying the solution in a fan shape so that the solution can be uniformly sprayed on the road surface or the like ≪ / RTI >

Roads, bridges, buildings, landscaping facilities, etc. require various types of solution spraying for various reasons. For example, the freezing of the road surface caused by snow or rain in the winter season can not only make the vehicle difficult to pass, but also cause a variety of traffic accidents, resulting in enormous loss of life and property. Therefore, spraying a solution of calcium chloride solution or salt solution The spraying solution which sprinkles the snowing solution while the storage tank containing the snowing solution is mounted on the vehicle is sprayed directly to the freezing section of the road surface or the spraying device fixedly installed on the roadside A snow solution spraying system that performs snow removal by spraying snow remover is also used.

In addition, due to the daytime heat of summer and winter, the temperature of facilities and road surfaces of various structures such as various structures are elevated to high temperature, so that the heat of the city is progressed and the nighttime is followed by tropical night phenomenon. Or water on the road surface. Also, it is cleaned by spraying water regularly or irregularly on facilities or roads for hygiene and urban beauty. In order to cool and clean the structures and roads, sprinkler vehicles are used, but in recent years, snow removal spraying systems such as spraying devices installed on the roadside for the purpose of snow removal are also used for cleaning and cooling purposes. In addition, in landscaping facilities, water is sprayed using a sprinkler or the like for the growth of trees.

However, in the case of a conventional solution spraying nozzle, a solution spraying nozzle used for a spraying system, a sprinkler, a sprinkler, etc., since the water stream ejected from the nozzle is sprayed only in a straight line, I have been.

Conventional techniques for uniformly distributing the spraying liquid on a large surface have employed a technique of spraying the spraying solution in several directions simultaneously using a plurality of nozzles or spraying the solution in several directions on the nozzle itself. However, when a plurality of nozzles are used, or when the solution is injected in multiple directions at the injection nozzle, the ejection pressure is insufficient, so that the injected solution can not be far away. In order to go far, And the pump capacity has to be increased. Therefore, in order to uniformly spray a large area over a long distance with a small pressure, a method of sequentially spraying the solution by changing the spraying direction of the solution by changing the angle of emission of the nozzle was used. However, for this purpose, the direction of the solution injection nozzle must be changed manually, or a driving means for automatically changing the spraying direction of the solution injection nozzle must be additionally provided. However, in order to separately provide the driving means for changing the spraying direction of the nozzles, a device has to be added and the nozzle has a complicated structure, so that the manufacturing cost has increased.

According to an aspect of the present invention, there is provided a spray device for spraying a solution in a fan shape, the spray device including an elastic nozzle and a pulsation prevention damper, And is sprayed in a fan shape while reciprocatingly oscillating in the left and right direction so as to spray the solution evenly on the road surface or the like, thereby improving the efficiency of solution spraying.

According to an aspect of the present invention, there is provided an injector capable of injecting a solution in a fan shape, comprising: a pipe coupling part detachably coupled to a solution supply pipe to receive a solution; A cylindrical pulsation prevention damper connected to the pipe coupling portion; A nozzle coupling portion connected to the pulsation prevention damper; A fixed nozzle detachably coupled to the nozzle coupling portion and having a jet opening whose cross section is rectangular or elliptical; And an elastic nozzle which is in the form of a tube of an elastic material and is fitted into the injection port and injects the solution while reciprocatingly oscillating the end portion of the solution when the solution is supplied; And a plurality of pixels.

형상이며, 상기 왕복진동하는 방향과 수직인 종단면은 평행선 또는 사다리 모양인 특징을 더 포함하는 것도 가능하다.In addition to the above-described features, it is also preferable that the inner diameter of the pulsation prevention damper is larger than the inner diameter of the solution supply pipe, and the inner diameter of the nozzle coupling portion is smaller than the inner diameter of the pulsation prevention damper. In addition, in addition to the above-mentioned features, the spraying device capable of spraying the solution according to the present invention in a fan shape has a longitudinal section parallel to the reciprocating direction of the injection port of the fixed nozzle

And the longitudinal section perpendicular to the reciprocating vibration direction may be parallel or ladder-like.

And further comprising a nozzle cover in addition to the features described above, wherein the nozzle cover is of a planar shape and is coupled in parallel with the direction of reciprocating oscillation, wherein the nozzle cover is a fan unit capable of fan- Wherein the nozzle lid includes a pair of stoppers and stopper fixing holes capable of adjusting a reciprocating vibration width of the elastic nozzle, the stopper fixing holes being formed as closed circular arcuate holes parallel to the arc, Wherein the pair of stoppers is inserted into the stopper fixing hole and is movably fixedly coupled along the closed circular hole to limit a reciprocating vibration width of the elastic nozzle on both sides of the elastic nozzle. As shown in Fig.

As described above, according to the present invention, the injector capable of injecting the solution in a fan shape has a structure in which a separate elastic nozzle is inserted into an injection hole of a fixed nozzle, and the elastic nozzle forms a circular arc, Since the solution injected by reciprocating vibration and spraying the solution can spread out in a fan shape, the solution can be sprayed evenly on the surface of the sprayed object, and the sprayed liquid is ejected from one nozzle hole instead of a plurality of nozzle holes Therefore, there is an effect that the solution can be sprayed far away even with a small pressure.

In addition, since the solution supplied through the solution supply pipe is sent to the nozzle through the anti-pulsation damper, it is possible to reduce the fluctuation phenomenon of the water pressure, that is, the pulsation phenomenon that can be generated by the solution supply pump, It is possible to prevent vibration. That is, there is an effect that it is possible to prevent the elastic nozzle from jumping in the vertical direction due to the pulsating motion due to the reciprocating vibration in the left and right direction, or rapidly changing the vibration width.

In addition, since the elastic nozzle is detachably fitted to the injection port of the fixed nozzle, the elastic nozzle deteriorates due to use for a long period of time, and when the elasticity is reduced or damaged, the elastic nozzle can be easily replaced.

형상으로도 할 수 있기 때문에 양쪽 돌출부분의 곡선부로 인하여 발생되는 힘이 탄성노즐에 가해져서 탄성노즐의 왕복진동 폭을 더 크게 할 수 있는 효과를 얻어 낼 수 있게 된다. Further, according to the present invention, the injector capable of spraying the solution in a fan shape has a rectangular or elliptical cross section of the injection port through which the solution is injected in the fixed nozzle, so that the elastic nozzle does not fluctuate in all directions, It is possible to reciprocate and oscillate uniformly, thereby preventing uneven injection of the solution. That is, when the end of the injection nozzle of the fixed nozzle has a circular shape, the end portion of the elastic nozzle fluctuates irregularly in all directions. However, if the injection nozzle of the fixed nozzle is formed into a rectangular shape or an elliptical shape as in the present invention, , The elastic nozzle vibrates to the left and right, and the vibration width thereof is constantly oscillated as long as the water pressure is constant. In addition, a longitudinal section parallel to the reciprocating vibration direction of the elastic nozzle in the injection port of the fixed nozzle

It is possible to obtain the effect that the force generated by the curved portions of the protruding portions is applied to the elastic nozzle so that the reciprocating vibration width of the elastic nozzle can be made larger.

The injection device according to the present invention may further include a fan-shaped nozzle cover having a flat surface, the nozzle cover being coupled in parallel with a direction in which the elastic nozzle oscillates reciprocally. Accordingly, air resistance due to vortex is generated between the elastic nozzle and the nozzle lid which are oscillated by the reciprocating vibration due to the nozzle lid, thereby preventing sudden upward movement of the elastic nozzle. Therefore, even though there is a pulsation-preventing damper for absorbing the pulsation, the sudden and large hydraulic pressure fluctuation is transmitted from the pump or the pipe for various reasons, and even if the pulsation-preventing damper does not prevent the damper from interfering with the reciprocating vibrating elastic nozzle and the nozzle lid It is possible to prevent the elastic nozzle from suddenly jumping upward due to the air resistance, thereby preventing unnecessary solution injection in the upward direction.

Further, according to the present invention, since the injection device capable of spraying the solution in a fan shape includes the stopper capable of adjusting the vibration amplitude of the elastic nozzle, the spray range of the solution sprayed from the nozzle can be easily There is an effect that can be adjusted. That is, when a large area spray is required, the oscillation width of the elastic nozzle can be increased by using the stopper, and when the rapid spraying is required for a narrow area, the oscillation width of the elastic nozzle can be reduced to be concentratedly applied to a narrow area It is effective.

In addition, although the term used in the present invention is selected as a general term that is widely used at present, there are some terms selected arbitrarily by the applicant in a specific case. In this case, since the meaning is described in detail in the description of the relevant invention, It is to be understood that the present invention should be grasped as a meaning of a term that is not a name of the present invention. The terminology used in the description of the embodiments is used only to describe a specific embodiment, and is not intended to limit the embodiments.

It should be understood, however, that the embodiments are not intended to be limited to the particular forms, but are to be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the embodiments.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a plan view of an injection device capable of injecting a solution in a fan shape according to the present invention, and FIG. 2 is a side view thereof. And FIG. 3 is an enlarged perspective view of only the fixed nozzle and the elastic nozzle in the injection device according to the present invention. As shown in FIGS. 1 and 2, an injector 10 for injecting a solution in a fan shape according to the present invention includes a pipe coupling unit 200 detachably coupled to a solution supply pipe 100 to receive a solution, A cylindrical anti-pulsation damper 300 connected to the pipe coupling part 200, a nozzle coupling part 400 connected to the pulsation prevention damper 300, a coupling part 400 detachably coupled to the nozzle coupling part 400, A fixed nozzle 500 having an injection port 550 having a rectangular or elliptical cross section and an elastic nozzle 600. The elastic nozzle is in the form of a tube of elastic material and is fitted into the injection port 550, It is preferable that the supply end portion 650 is caused to reciprocally vibrate while spraying the solution.

Therefore, the solution supplied through the solution supply pipe 100 passes through the pipe coupling part 200, the anti-pulsation damper 300, the nozzle coupling part 400, and the fixed nozzle 500 in order, The elastic nozzle 600 may be made of a material having elasticity such as rubber, silicone, or urethane so that the elastic nozzle 600 is sprayed from the injection port 550 of the fixed nozzle 500 When the force of the jetting pressure is applied in the left-right direction (refer to FIG. 1) of the jetting port 550, the jetting pressure is deflected in one of the directions in which the force is applied, It is preferable to repeat the bending and bending in the opposite direction again. That is, the jet port of the fixed nozzle 500 is positioned so that the solution jet port 650 of the elastic nozzle 600 vibrates in the left-right direction of the jet port 550 on the basis of FIG. 1, It is preferable that the cross section is a rectangle or an ellipse, more preferably both sides are round.

When a solution supply pressure applied by a pump (not shown) or the like is applied through the solution supply pipe 100, a certain pressure is formed in the injection device 10, 550 is sprayed through the solution jetting port 650 of the elastic nozzle 600 and the jetted solution is reacted against the solution jetting port 650. Accordingly, the solution jetting port 650 of the elastic nozzle 600 is pushed backward, and when the force is applied to the solution jetting port 650 to bend the elastic jetting nozzle 600, the elastic jetting nozzle 600 The solution jetting direction of the solution jetting port 650 is changed. When the direction of spraying the solution is changed, the direction of the reaction applied to the solution jetting port 650 is also changed, and the direction in which the elastic nozzle 600 is bent is changed as the direction of the reaction is changed, ) Is changed again, and this situation is repeated. In this case, if the injection nozzle 550 of the fixed nozzle 500 is circular, the elastic nozzle 600, which receives the reaction, is bent in four directions without being predicted. Therefore, do.

3, since the injection port 550 of the fixed nozzle 500 has a rectangular or elliptical cross section, the injection pressure of the solution injected from the injection port 550 is a rectangular shape, The elastic nozzle 600 is bent only in the left-right direction (S-S 'direction in FIG. 1) of the jetting orifice 550 having a rectangular shape or an elliptical shape, So that it oscillates reciprocally with a certain range of width.

As described above, it is preferable that the pulsation prevention damper 300 is included between the pipe coupling part 200 and the nozzle coupling part 400. The inner diameter of the pulsation prevention damper 300, It is more preferable that the inner diameter of the nozzle coupling part 400 is larger than the inner diameter 101 of the solution supply pipe 100 and the inner diameter of the nozzle coupling part 400 is smaller than the inner diameter of the pulsation prevention damper 300. In this case, the pulsation preventing damper 300 serves as a buffer for temporarily storing the solution supplied through the solution supply pipe 100, and the pulsation transmitted from the pump through the piping system is supplied to the solution supply pipe 100, It can be absorbed by the pulsation prevention damper 300. If the pulsation is transmitted to the elastic nozzle 600 without the pulsation prevention damper 300, the elastic nozzle 600 vibrates irregularly due to pulsation, and vibrates not only in the right and left direction but also in the vertical direction Whereby the solution supply can be made nonuniform. Therefore, it is preferable to include the pulsation prevention damper 300 in the spray device capable of spraying the solution according to the present invention in a fan shape.

As described above, it is preferable that the elastic nozzle 600 is detachably fitted to the fixed nozzle 500. By using the elastic force of the elastic nozzle 600 made of an elastic material, 500, or a coupling means such as a separate fastening band may be used. It is preferable that the fixed nozzle 500 is detachable to the nozzle coupling part 400 by screwing or socket coupling. The injection port 550 of the fixed nozzle 500 is rectangular or elliptical, Since it is possible to vibrate the elastic nozzle only in a direction parallel to the elliptical long direction surface, it is important to properly align the direction of the injection port 550 when the fixed nozzle is engaged. Therefore, it is more preferable that the fixing nozzle 500 is coupled to the nozzle coupling part 400 so as to be coupled to the nozzle coupling part 400 with a stopper or a stopper so that the nozzle can be rotated only by a predetermined distance, , And it is more preferable that the fitting position is determined so that the direction of the injection port (550) coincides with the fitting position by the socket coupling. Meanwhile, the fixed nozzle 500 is a nozzle structure capable of ejecting the solution to a sufficiently far distance even when the elastic nozzle 600 is removed. Therefore, even if the elastic nozzle 600 is damaged or lost, I can play a role.

형상 하는 것도 바람직하며, 도 4c에서 보는 바와 같이 일정한 지점에서부터 점점 좁아지다가 상기 분사구(550)에 가까이 와서는 평행하게되는

형상으로 하는 것도 바람직하다. 4A is a cross-sectional view of the injection port 550 seen in the direction of arrow A in a perspective view (FIG. 3) of the fixed nozzle 500, and FIGS. 4B and 4C are cross- FIG. 3 is a vertical cross-sectional view in the BB 'direction of the perspective view (FIG. 3). As shown in FIG. 4A, it is preferable that a cross section of the injection port 550 is a rectangle having both sides rounded. However, it is also possible to make a non-round rectangular shape or an elliptical shape, whichever shape it becomes, it is preferable that the elastic nozzle 600 should not be vibrated wide and the side where vibration should be made narrow. As shown in FIG. 4B, the longitudinal direction of the fixed nozzle 500 in the direction of BB 'is gradually narrowed from a fixed point to a vertical position, as shown in FIG. 4B, since the fixing part 510 of the fixed nozzle has a cylindrical shape and a cylindrical part 520 having a constant length. Losing trapezoidal

And as shown in FIG. 4C, it is preferable to form a plurality of ink droplets that are gradually narrowed from a certain point, become parallel to the ejection port 550,

Shaped.

형태로 하는 것이 바람직하다. 즉, 상기 고정노즐(500)은 상기 노즐결합부(400)와 결합되는 결합부(510)에서 일정길이 만큼의 원통부(520)를 지난 일정지점(530a)부터 좌우로 확대되는 곡선부(530)를 형성시키고, 상기 곡선부(530)가 종료되는 지점(530b)에서 부터 상기 분사구(550)까지 일정구간(540)은 점진적으로 단면적이 좁아지도록 하는 것이 바람직하다. 이렇게 하는 경우 상기 원통부(520)를 통과하던 용액이 상기 곡선부(530)에서 좌우로 확대되는 흐름을 형성하기 때문에 상기 일정구간(540)의 좌우측 벽면을 향하게 되며, 이로 인하여 상기 분사구(550)에서 좌우방향으로 가해지는 분사압력은 더 커지게 되며, 상하부분으로 가해지는 압력은 상대적으로 줄어들게 된다. 따라서 상기 고정노즐(500)의 C-C’ 방향종단면을

형태로 하게되면, C-C’ 방향 종단면을 평행상태로 하는 것보다 상기 탄성노즐(600)의 좌우방향 왕복진동이 더욱 안정적으로 될 뿐만 아니라 진동하는 폭을 더욱 크게 하는 것이 가능해 진다. 즉, 동일한 압력으로 분사하더라도 상기 고정노즐(500)에 상기 곡선부(530)를 형성하는 경우 상기 탄성노즐(600)이 진동 폭이 더 커지게 된다. FIG. 4D is a vertical cross-sectional view in the CC 'direction of the perspective view (FIG. 3) of the fixed nozzle 600. In the injection device 10 according to the present invention, But it is also possible to make them parallel to each other, but as shown in Fig. 4D

Is preferable. That is, the fixed nozzle 500 includes a curved portion 530 extending from a certain point 530a extending from the predetermined point 530a through a cylindrical portion 520 of a predetermined length in the coupling portion 510 coupled with the nozzle coupling portion 400, And a predetermined section 540 from the point 530b where the curved portion 530 ends to the injection port 550 gradually decreases in cross sectional area. In this case, since the solution passing through the cylindrical portion 520 forms a flow expanding to the left and right in the curved portion 530, it faces the right and left wall surfaces of the predetermined section 540, The injection pressure applied in the left-right direction becomes larger, and the pressure applied to the upper and lower portions becomes relatively smaller. Therefore, the vertical cross-section in the C-C 'direction of the fixed nozzle 500

The reciprocating vibration of the elastic nozzle 600 in the lateral direction can be made more stable as well as the oscillation width can be made larger than that in the longitudinal direction vertical direction in the C-C 'direction. That is, even if the nozzle is sprayed with the same pressure, the elastic nozzle 600 has a larger vibration width when the curved portion 530 is formed in the fixed nozzle 500.

FIG. 5 is a view showing a case where the fan spraying is made parallel to the object surface in the spraying apparatus according to the present invention, and FIG. 6 is a view showing a state in which, in the spraying apparatus according to the present invention, As shown in FIG. 5, when the injector 10 is installed to be vibrated in a direction parallel to the ground surface, that is, when the long side of the jetting port 550 of the fixed nozzle 500 is parallel to the ground surface E The elastic nozzle 600 vibrates in parallel with the ground surface E (S-S ') so that the spray of the solution is sprayed in a fan shape in parallel with the surface E as shown in FIG. 5 do. 6, when the injector 10 is installed so as to be vibrated in a direction perpendicular to the ground surface E, that is, when the long side of the injection port 550 of the fixed nozzle 500 is longer than the long side 5, the elastic nozzle 600 vibrates in a direction perpendicular to the ground surface E (T-T '), so that the spraying of the solution is performed on the surface E In this case, it is advantageous in that the solution can be sprayed evenly from the near side to the far side of the injector 10 among the surface E of the surface.

Meanwhile, FIG. 7 is a plan view showing another embodiment of a spraying device capable of spraying a solution in a fan shape according to the present invention, and FIG. 8 is a side view thereof showing a case where the spraying device is installed on a road. 7 and 8, the spray device 10 capable of spraying the solution in a fan shape according to the present invention includes the pipe coupling part 200, the pulsation prevention damper 300, the nozzle coupling part 400 ), A nozzle cover 700 in addition to the fixed nozzle 500 and the elastic nozzle 600. As shown in FIG. 7, the nozzle lid 700 has a flat fan-shaped cross section and is fixed to a bracket 800 for fixing the injector 10 by a coupling means 710 as shown in FIGS. 7 and 8 It is preferable to make the elastic nozzle 600 parallel to the direction (S-S ') in which the elastic nozzle 600 oscillates reciprocally. When the nozzle lid 700 is included, air resistance is generated between the elastic nozzle 600 oscillating and reciprocating and the nozzle lid 700 due to vortex generated during vibration, So that it can prevent sudden upward movement of the elastic nozzle 600. Therefore, even if there is a pulsation-preventing damper for absorbing the pulsation, sudden and large hydraulic pressure fluctuations are transmitted from the pump or pipe for various reasons, and even if the pulsation-preventing damper does not prevent the damper from interfering with the pulsation- It is possible to prevent the elastic nozzle from suddenly jumping upward due to the resistance, thereby preventing the unnecessary solution injection in the upward direction.

And FIG. 9 is a plan view showing another embodiment of a spray device capable of spraying a solution in a sector according to the present invention, and FIG. 10 is a side view thereof. As shown in FIGS. 9 and 10, according to another embodiment of the present invention, an injection device capable of injecting a solution in a fan shape can adjust the reciprocating vibration width of the elastic nozzle 600 to the nozzle lid 700 It is preferable to include the stopper 720 and the stopper fixing hole 730, which are provided in the stopper 720. Here, the stopper fixing hole 730 is formed as a circular arc-shaped hole on the nozzle lid 700 in parallel with the arc drawn by the solution jetting port 650 when the elastic nozzle 600 oscillates reciprocally The pair of stoppers 720 are inserted into the stopper fixing holes 730 and movably fixed along the stopper fixing holes 730 so that the elastic nozzles 600 on both sides of the elastic nozzles 600 And the oscillation width of the reciprocating oscillation of the oscillator is limited.

That is, when intensive jetting to a narrow area is required, each of the pair of stoppers 720 is moved toward and fixed to the elastic nozzle 600, so that the vibration width of the elastic nozzle 600 is The reciprocating vibration width of the elastic nozzle 600 can be narrowed because the vibration occurs only up to the point where the pair of stoppers 720 are fixed. On the other hand, when a large area is required to be sprayed, the pair of stoppers 720 are respectively moved and fixed away from the elastic nozzle 100, so that the vibration width of the elastic nozzle 100 is large . Therefore, it is possible to easily adjust the spraying range of the solution of the fan-shaped sprayed from the nozzle according to the conditions of the road or facilities.
