Description

Waterjet waste water collection device

This creation is about a collection device, especially a water jet waste water collection device that receives the waste water generated after water jet cutting.

Most of the cutting technologies in the industry are often accompanied by thermal stress generated by the interaction between the cut object and the object to be cut during the cutting process, which in turn increases the temperature of the object to be cut and changes its chemical properties. Therefore, the waterjet cutting technology in which the heat generated by the object to be cut is immediately washed away by the high-speed and high-pressure water flow during the cutting process is widely used. However, if the waste water that takes away the heat energy is not properly treated, it will also cause the environment to be messy.

Referring to FIG. 1, one of the current wastewater treatment methods is to set a water basin 92 under the workpiece 91, and use the water basin 92 to receive the free-falling wastewater 93, so as to achieve the effect of receiving the wastewater 93 without overflowing. However, considering that the waste water 93 just cut is still in a high-speed and high-pressure state, if it is directly injected into the water basin 92, it is easy to cause the waste water 93 in the water basin 92 to splash upwards and adhere to the workpiece 91 or parts of the unit. This in turn causes messiness and increases the risk of corrosion, so the treatment method still needs to be improved.

Therefore, the purpose of this creation is to provide a waterjet waste water collection device that receives the waste water generated after waterjet cutting and does not let the waste water splash out.

Therefore, the water jet waste water collection device of this invention is suitable for receiving waste water flowing along a flow path, and includes a containing unit. The accommodating unit includes a bottom wall member arranged downstream of the waste water, a wall member extending upward from the periphery of the bottom wall member, and a wall member covering the wall member and matching with the bottom wall member and the wall member A top wall member defining a liquid containing space, wherein the top wall member has a liquid inlet hole that penetrates the top wall member along the flow path and communicates with the liquid containing space.

The effect of this creation is that with the setting of the liquid inlet, the waste water that is still in a high-speed and high-pressure state after waterjet cutting will continue to enter the liquid-containing space directly along the flow path, and bounce up when it hits the bottom wall. The splashed water droplets will be stopped by the top wall part, which achieves the effect of recycling waste water and effectively preventing corrosion of workpieces and unit parts.

The other features and effects of the present invention will be clearly presented in the embodiment with reference to the drawings, in which: Figure 1 is a schematic diagram illustrating an existing wastewater treatment method; Figure 2 is a three-dimensional exploded view illustrating the present invention An embodiment of a knife waste water collection device; FIG. 3 is a schematic diagram illustrating the mechanism for recycling waste water in this embodiment; and FIG. 4 is a schematic diagram illustrating that a barrier reduces the kinetic energy of the waste water.

2 and 3, an embodiment of the inventive waterjet wastewater collection device is suitable for receiving wastewater W flowing along a flow path C, and this embodiment includes a containing unit 1 arranged on the flow path C , A buffer unit 2 arranged in the accommodating unit 1, and a drainage unit 3 arranged on one side of the accommodating unit 1.

Before further explaining the detailed technical features of the components, it is necessary to explain first that the waste water W is formed by cutting a workpiece I from a water jet nozzle N along the axial flow path C and spraying it downwards. The workpiece I and therefore the waste water W are still at a high speed and high pressure.

The accommodating unit 1 includes a bottom wall member 11 arranged downstream of the waste water W, a wall member 12 extending upward from the periphery of the bottom wall member 11, and a wall member 12 that detachably covers the wall member 12 and is connected to the bottom wall. The wall member 11 and the blocking wall member 12 cooperate to define a top wall member 14 of a liquid containing space 13, wherein the top wall member 14 has a top wall member 14 along the flow path C that penetrates the top wall member 14 and communicates with the liquid containing space 13 of the liquid inlet 141. It should be particularly noted that, in order to effectively receive the waste water W, the accommodating unit 1 preferably moves corresponding to the waterjet nozzle N, so that the liquid inlet 141 is always located on the flow path C.

The buffer unit 2 includes a blocking member 21 arranged at intervals on the flow path C and suitable for blocking the flow of the waste water W. It is worth mentioning that in this embodiment, the blocking member 21 is preferably a cylindrical shape extending along an axis 22 and rotatable around the axis 22, and the axis 22 does not intersect with the flow path C due to the containment. The mounting unit 1 and the blocking member 21 need to be exposed to a humid environment for a long time, and need to withstand the impact of the high-speed and high-pressure flowing waste water W. Therefore, they are preferably made of rust-proof, high-strength, high-hardness, and corrosion-resistant materials.

The drainage unit 3 is arranged on the wall blocking member 12 and above the bottom wall member 11, and is suitable for draining the waste water W in a vacuum extraction manner.

Referring to Figures 3 and 4, the implementation of this embodiment will be described in detail below. After the water jet cuts the workpiece I to form the waste water W, it will continue to flow along the aforementioned flow path C because it is still in a high-speed and high-pressure state. In this embodiment, by providing the liquid inlet 141 on the linear flow path C, the high-speed and high-pressure waste water W will enter the liquid containing space 13 along the liquid inlet 141, even if it directly collides with the bottom wall If the piece 11 rebounds upwards, it will also be blocked by the top wall piece 14 located above and not overflow.

Considering that the waste water W rebounding upward may still overflow from the liquid inlet 141, this embodiment provides the following two mechanisms to solve the problem, namely, the buffer unit 2 arranged at intervals in the flow path C, and the waste water W The buffer B accumulated in the liquid containing space 13. Since the axis 22 of the blocking member 21 is not staggered with the flow path C, the waste water W and the blocking member 21 are not substantially on the same extension line. When the waste water W enters the liquid containing space 13 along the flow path C, Instead of hitting the blocking member 21 head-on, it bounces diagonally and departs from the flow path C as shown in FIG. 3. Also, because the liquid inlet 141 is provided on the flow path C, the waste water W sprayed obliquely is more It is easily blocked by the top wall member 14 instead of ejecting from the liquid inlet 141 located on the flow path C.

4, after cutting the workpiece I with higher hardness, the required water jet strength is higher, and the intensity of the waste water W generated will be higher, even if the blocking member 21 cannot withstand the impact of the waste water W and is penetrated or penetrated. Erosion, because the axis 22 is not staggered with the flow path C, the impact force of the wastewater W exerts a moment with respect to the axis 22, so that the stopper 21 starts to surround the axis 22 as shown in FIG. 4 Rotate to advance Steps to absorb the kinetic energy of the waste water W, and reduce its cutting ability. Incidentally, when the blocking member 21 is damaged and cannot be used, it is only necessary to open the top wall member 14 detachably covering the wall blocking member 12 and replace the blocking member 21, which is simple and convenient.

Then, except for the part of the blocking member 21, the remaining high-speed and high-pressure wastewater W will first collide with the buffer B and decelerate, before further colliding with the bottom wall member 11, reducing the rebound speed characteristics, in addition to avoiding the waste water W from The overflow of the liquid inlet 141 can also prevent the waste water W from directly hitting the bottom wall member 11 and causing damage, and the waste water W flowing into the buffer solution B will also accumulate and form a new buffer solution B, which will continue to assist in slowing down the follow-up The impact of the wastewater W entering it.

Since the water level of the buffer B will rise as the cutting operation progresses, with the arrangement of the drainage unit 3, the difference in pressure can be used to vacuum extract the buffer B and perform subsequent processing. In this way, it is possible to achieve a drainage effect without moving the embodiment.

In summary, the water jet waste water collection device of the present invention uses the liquid inlet 141, the buffer unit 2, the top wall member 14, and the buffer solution B to allow the high-speed and high-pressure waste water W to enter from the water jet waste water collection device. After the liquid hole 141 enters the liquid containing space 13, it will first collide with the buffer unit 2 and bounce diagonally to be blocked by the top wall member 14. At this time, most of the kinetic energy of the waste water W has been absorbed by the blocking member 21, and then The buffer B reduces the remaining impact of the waste water W, and cooperates with the drainage unit 3 to achieve the effect of efficiently collecting the waste water W without overflowing, so it can indeed achieve the purpose of cost creation.

However, the above are only examples of the present model, and should not be used to limit the scope of the implementation of the present model. Anything in accordance with the scope of the patent application for the present model and the description of the patent Simple equivalent changes and modifications made to the contents of the book are still within the scope of this new patent.
