DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1
[0026] This embodiment discloses an energy-saving oil-water separation box, referring to Figure 1 , Figure 2 As shown, it includes a box body 1, which serves to store circulating water. The circulating water is introduced into the box body 1, and after separation treatment in the box body 1, oil stains in the circulating water can be removed, so that the circulating water can be in a relatively clean state.
[0027] In this embodiment, the energy-saving oil-water separation box is mainly used in the waste gas system of the printing and dyeing industry. Since a part of the oil in the dye auxiliaries of printing and dyeing will enter the waste gas, the waste oil in the waste gas will enter the spray water, which will easily cause oil pollution in the spray water. Through the oil-water separation process, the spray water can be recycled.
[0028] Reference Figure 2 As shown, a partition 1 8 and a partition 2 9 are provided in the box body 1, and the inner cavity of the box body 1 is divided into a chamber 1 101, a chamber 2 102 and a chamber 3 103 which are distributed on the left and right respectively by the partition 1 8 and the partition 2 9, and the chamber 2 102 is located in the middle position.
[0029] The partition 1 8 is provided with a through hole 1 81, which is located at the lower side of the partition 1 8, and the partition 2 9 is provided with a through hole 2 91, which is located at the upper side of the partition 2 9, and the through hole 2 91 is higher than the through hole 1 81. When the equipment is working, the circulating water enters from the chamber 1 101, and the oil in the circulating water is at the upper layer of the liquid level. The relatively clean water in the chamber 1 101 can enter the chamber 2 102 from the through hole 1 81. The water in the chamber 2 102 has separated the waste oil, and there will be certain precipitated impurities in the lower part of the chamber 2 102. Relatively clean circulating water is obtained in the upper layer of the chamber 2 102, and the upper layer of circulating water can enter the chamber 3 103 from the through hole 2 91, and then the relatively clean circulating water in the chamber 3 103 is discharged through the outlet pipe 4 to achieve recycling.
[0030] The chamber three 103 is connected with a water outlet pipe 4, and the water outlet pipe 4 is provided with a water outlet valve 41 and a water outlet pump 42, and the water flow output from the water outlet pipe 4 is controlled by the water outlet pump 42 and the water outlet valve 41.
[0031] On the side of the inner wall of the chamber 101 opposite to the partition 8, i.e., on the left side in the figure, there are an oil discharge hole 51 and a slag discharge hole 61. The oil discharge hole 51 is located at the upper part of the chamber 101, close to the liquid level in the chamber 101, and the slag discharge hole 61 is located at the lower part of the chamber 101. The oil discharge hole 51 is connected to the oil discharge pipe 5, and the slag discharge hole 61 is connected to the slag discharge pipe 6. The oil discharge pipe 5 and the slag discharge pipe 6 are both connected to the sewage pipe 7, and the slag discharge pipe 6 is provided with a slag discharge valve 62.
[0032] The chamber 101 is provided with a water inlet pipe 3, through which circulating liquid can be input into the chamber 101. A cover 2 is provided on the upper part of the chamber 101, and the cover 2 can prevent the waste oil on the upper side of the chamber 101 from volatilizing and causing pollution.
[0033] Furthermore, a water pusher 10 and a water pusher 2 11 are provided in the chamber 101. The two water pushers can drive the water flow in the chamber 101 to circulate, and in the process of circulation, the oil pollution in the chamber 101 can be collected, and the oil-water separation treatment of the circulating water can be facilitated.
[0034] The water pusher 10 and the water pusher 2 11 are both located on one side of the chamber 101 near the partition 1 8, and the water pusher 10 is located at the lower part of the water pusher 2 11. The water pusher 10 can push water upward at the bottom of the chamber 101, and the water pusher 2 11 can push water in the direction away from the partition 1 8. Under the action of the water pusher 10 and the water pusher 2 11, the water in the chamber 101 can be driven to circulate in a counterclockwise direction.
[0035] In this embodiment, water pusher 10 and water pusher 2 11 refer to devices that can drive water to move, which can be facilitated by aeration to drive water flow movement by bubbling, or by using propeller blades to drive water flow movement, so as to push the water flow.
[0036] Specifically, the water pusher 10 is an aeration device, which has an upward aeration hole, and can spray bubbles toward the upper side. The bubbles can drive the water flow upward during the floating process. The water pusher 2 11 is a paddle driven by a motor. When the paddle rotates, it can move toward (such as Figure 2 The water in the chamber 101 is pushed in the left direction to realize the liquid circulation in the chamber 101. During the circulation process, the water flow in the chamber 101 can drive the upper layer of oil to converge toward the oil discharge hole 51, which can facilitate the convergence of oil pollution on the upper layer of sewage.
[0037] Reference Figure 2 As shown, a water baffle 82 is provided on the outer side of the through hole 1 81 in the chamber 101. The water baffle 82 can block the outer side of the through hole 1 81, and a certain gap is formed between the water baffle 82 and the through hole 1 81, which can play a role of slowing down the flow on the outer side of the through hole 1 81, thereby preventing the sedimentation of the lower layer of sewage from directly entering the chamber 2 102.
[0038] The lower edge of the water baffle 82 is lower than the through hole 1 81, and an inclined plate 83 is connected to the upper side of the water baffle 82, and the inclined plate 83 is inclined toward the partition 1 8. The inclined inclined plate 83 can guide the water flow, thereby making the water flow process smoother.
[0039] The water retaining plate 82 is located between the water pusher 10 and the partition 8 to prevent the water pusher 10 from directly bringing the oil impurities in the sewage into the through hole 81 during the water pushing process. The water pusher 11 is located above the inclined plate 83, so that the circulating water can be more smoothly in the circulation process.
[0040] Embodiment 2
[0041] This embodiment discloses an energy-saving oil-water separation box. Figure 3 , Figure 4 Provide detailed explanation.
[0042] A liquid guide 12 is provided inside the chamber 101. The liquid guide 12 is located on the upper layer of the liquid surface and can adjust the height. The liquid guide 12 is provided with a plurality of liquid guide channels 120, which are open toward the water pusher 2 11 and the oil drain hole 51. The liquid guide channels 120 in the liquid guide 12 can guide the oil in the upper layer, thereby making the movement of the oil in the upper layer smooth and stable.
[0043] In addition, the liquid guide 12 has a certain volume, and the liquid guide 12 can be adjusted up and down to adjust its volume immersed below the liquid surface, thereby adjusting the liquid level of the liquid surface. When the liquid level is too low, the liquid guide 12 can be adjusted downward so that more of the liquid guide 12 is immersed below the liquid surface, thereby driving the liquid surface to rise; when the liquid level is too high, the liquid guide 12 can be adjusted upward so that less of the liquid guide 12 is immersed below the liquid surface, and the liquid surface will drop. By adjusting the height position of the liquid surface, the height of the oil on the upper side of the liquid surface can be adapted to the position of the oil drain port, so that the oil can be discharged smoothly.
[0044] Specifically, the liquid guide 12 can adopt a structure of multiple pipes, including multiple pipes, each of which is made of floating materials, and each pipe is fixed as a whole by a bracket. A liquid guide channel 120 is formed inside the pipe to guide the upper oil. In addition, there is a gap between the pipes, which also allows the oil floating in the middle position of the chamber 101 to the upper layer of the chamber 101.
[0045] A plurality of pull ropes 121 are connected to the lower part of the liquid guide 12. A plurality of reel wheels 122 are installed at the bottom of the chamber 101. The reel wheels 122 correspond to the pull ropes 121 one by one. The pull ropes 121 are reeled by the reel wheels 122. The height of the liquid guide 12 can be adjusted and controlled by adjusting the reeling of the pull ropes 121.
[0046] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
