Description

Technical Field

[0001] The invention relates to the field of foam separators, in particular to a pig manure water foam separation device. Background Art

[0002] Foam separation is one of the new separation technologies developed in the past decade. It is mainly based on the principle of surface adsorption and uses the bubbles formed in the liquid phase by ventilation bubbling as carriers to separate solutes or particles in the liquid phase.

[0003] At present, the method used for foam separation is to set an aeration pipe at the bottom of the tank body, and set a water outlet and a foam outlet at the top of the tank body respectively, and use the characteristics of bubbles with low density and easy floating on the water surface to discharge water and foam through different outlets respectively.

[0004] Although the above foam separation device can separate most of the foam, it is difficult to separate fine foam. For example, most of the foam floating in pig manure water is in the form of small particles. The conventional foam separation device has a poor separation effect, and the existing foam separation device has poor real-time effect when performing foam separation, so the sewage treatment speed is poor.

[0016] In one embodiment, one end of the air flow channel is perpendicular to the end of the foam channel, and the other end of the air flow channel is bent toward the foam outlet and communicated with the middle section of the foam channel.

[0017] In one embodiment, the foam channel includes a foam inlet passage, a foam outlet passage and a curved passage, the foam inlet passage and the foam outlet passage are oriented in the same direction and respectively pass through both sides of the first fixing ring, the curved passage is bent and fits on the upper side of the second fixing ring, and both ends of the curved passage are respectively connected to the foam inlet passage and the foam outlet passage.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Combine the following Figures 1 to 6 The invention discloses a foam separation device for separating pig manure from water.

[0033] like Figure 1 and Figure 2As shown, in one embodiment, a pig manure water foam separation device includes a rectangular pipe 100, an aeration pipe 200, a first fixing ring 310, a foam channel 330 and an air flow channel 340. A water flow channel 110 is arranged inside the rectangular pipe 100, a hemispherical groove 120 is opened at the top of the rectangular pipe 100, and the lower side of the hemispherical groove 120 is located in the water flow channel 110; the aeration pipe 200 is arranged at the bottom of the water flow channel 110, and is used to aerate the water flow and generate foam; the first fixing ring 310 is rotatably arranged at the bottom of the water flow channel 110. The foam channel 330 is arranged in the first fixing ring 310, one end of which passes through one side of the first fixing ring 310 and is connected to the water flow channel 110, and the other end passes through the other side of the first fixing ring 310 and is connected to the outside; the air flow channel 340 is arranged in the first fixing ring 310, one end of which passes through the first fixing ring 310 and is connected to the outside, and the other end passes through the foam channel 330 and faces the end of the foam channel 330 connected to the outside.

[0034] Specifically, when in use, the first fixing ring 310 is rotated to a suitable angle so that one end of the foam channel 330 is tilted downward and opposite to the direction of the water flow. During this process, the aeration pipe 200 is always running, and the aeration hole 210 generates bubbles and takes away the particulate impurities in the pig manure water and floats to the surface of the water flow. At this time, during the flow of water, smaller bubbles will enter the foam channel 330 along the surface of the water flow. At the same time, there is air flow in the air flow channel 340, and the flow direction coincides with the second half of the foam channel 330. Therefore, the foam entering the foam channel 330 will, on the one hand, move toward the end of the foam channel 330 connected to the outside under the action of foam accumulation and water flow. On the other hand, under the influence of air flow and negative pressure adsorption, the foam will also be pushed to the end of the foam channel 330 connected to the outside.

[0035] When the above-mentioned pig manure water foam separation device is in use, the first fixing ring 310 is rotated to a suitable angle so that one end of the foam channel 330 is tilted downward and opposite to the water flow direction. During this process, the aeration pipe 200 is always running, generating bubbles and taking away the particulate impurities in the pig manure water and floating them to the surface of the water flow. At this time, during the flow of water, smaller bubbles will enter the foam channel 330 along the surface of the water flow. At the same time, there is air flow in the air flow channel 340, and the flow direction coincides with the second half of the foam channel 330. Therefore, the foam entering the foam channel 330 will move toward the end of the foam channel 330 connected to the outside under the action of foam accumulation and water flow. On the other hand, under the influence of air flow and negative pressure adsorption, the foam will also be pushed to the end of the foam channel 330 connected to the outside. The separation effect of the separation device is relatively good, and it can be separated in real time during the flow of water, and the sewage treatment effect is better.

[0036] like Figure 3 As shown, in one embodiment, a plurality of first fixing rings 310 are linearly spaced apart, and two ends of the foam channel 330 passing through the first fixing ring 310 are respectively a foam inlet 311 and a foam outlet 312, and an elastic baffle 350 is fixed on the side of the foam inlet 311 away from the water flow direction. In the first state, the elastic baffle 350 is in an arc-shaped extended state, and in the second state, the elastic baffle 350 is in an arc-shaped contracted state.

[0037] Specifically, in the first state, the foam channel 330 remains vertical or inclined and the angle with the vertical direction is less than 45 degrees. At this time, the water flow can just flush the foam inlet 311 and the elastic baffle 350, and the elastic baffle 350 can block the foam on the surface of the water flow. During the accumulation process, the foam will enter the foam channel 330 through the foam inlet 311. In the second state, the foam channel 330 remains inclined and the angle with the vertical direction is greater than 40 degrees and less than 60 degrees. At this time, the water flow will flush to the other side of the elastic baffle 350, and the elastic baffle 350 will bend due to the flushing force of the water flow, thereby preventing the foam blocked on its inner side from being flushed away by the water flow, and the foam separation effect is more stable.

[0038] In one embodiment, a plurality of partitions 130 are linearly spaced apart at the top of the water flow channel 110. The partitions 130 are arranged along the top of the rectangular pipe 100 and the lower side of the hemispherical groove 120. There is a set interval between the bottom end of the partition 130 and the top of the rectangular pipe 100 and the lower side of the hemispherical groove 120. A diversion channel 140 is formed between two adjacent partitions 130, and the hemispherical groove 120 and the diversion channel 140 are connected via a connecting port 150.

[0039] Specifically, by arranging a plurality of diversion channels 140 side by side at the top of the water flow channel 110, a plurality of first fixed rings 310, foam channels 330 and air flow channels 340 are correspondingly arranged, and the first fixed ring 310 can be rotated and the angle adjusted individually according to the foam separation state in the water flow, so that each foam channel 330 and the elastic baffle 350 can correspond to the foam separation state in different diversion channels 140, and the practicality is relatively good.

[0040] like Figure 4 As shown, in one embodiment, a plurality of hemispherical grooves 120 are linearly spaced apart at the top of a rectangular pipe 100, an aeration pipe 200 is disposed between two adjacent hemispherical grooves 120, a fixing plate 160 is disposed at both ends of the hemispherical groove 120, a rotating rod 170 is rotatably installed between the two fixing plates 160, a driver 400 is disposed on the outside of the fixing plate 160, and the driver 400 is used to drive the rotating rod 170 to rotate.

[0041] Specifically, the driver 400 is used to uniformly drive the plurality of first fixing rings 310 to change the use state of the device, such as changing the device in the first state to the device in the second state. By arranging the aeration tube 200 between two adjacent hemispherical grooves 120, the foam will flow with the water flow during the foam separation, and the foam will not be washed away by the water flow during the rising process, but can accurately enter the bottom of the adjacent hemispherical grooves 120.

[0042] like Figure 5 As shown, in one embodiment, a second fixing ring 320 is coaxially disposed inside the first fixing ring 310 , both ends of the foam channel 330 are disposed along the diameter of the first fixing ring 310 , and the middle section of the foam channel 330 is attached to the second fixing ring 320 .

[0043] Specifically, by providing a curved portion in the foam channel 330 , the foam can be stably located at the current position when being pushed to a certain distance in the foam channel 330 , and the problem of foam sliding down due to a small amount of subsequent foam will not occur.

[0044] In one embodiment, one end of the airflow channel 340 is perpendicular to the end of the foam channel 330 , and the other end of the airflow channel 340 is bent toward the foam outlet 312 and communicated with the middle section of the foam channel 330 .

[0045] Specifically, by connecting one end of the airflow channel 340 to the curved middle section of the foam channel 330, the foam entering the middle section of the foam channel 330 can continue to move to the foam outlet 312 under the push of the airflow, thereby ensuring the stability and efficiency of the foam separation process.

[0046] In one embodiment, the foam channel 330 includes a foam inlet passage 331, a foam outlet passage 333 and a curved passage 332. The foam inlet passage 331 and the foam outlet passage 333 are oriented in the same direction and respectively pass through both sides of the first fixing ring 310. The curved passage 332 is bent and fits on the upper side of the second fixing ring 320, and both ends of the curved passage 332 are respectively connected to the foam inlet passage 331 and the foam outlet passage 333.

[0047] The airflow channel 340 includes an air inlet passage 341, an air outlet passage 343 and a detour passage 342. The air inlet passage 341 is perpendicular to the foam inlet passage 331 or the foam outlet passage 333 and passes through the first fixing ring 310. The air outlet passage 343 is parallel to the foam inlet passage 331 or the foam outlet passage 333 and passes through the middle section of the curved passage 332. The ends of the air inlet passage 341 and the air outlet passage 343 are connected through the detour passage 342.

[0048] Specifically, through the above-mentioned structural arrangement, the foam inlet passage 331, the foam outlet passage 333 and the air inlet passage 341 are respectively located at one side of the surface of the first fixed ring 310, and the angle between them is 90 degrees, so that after the first fixed ring 310 is rotated and the angle is adjusted, the air supply equipment connected to the air inlet passage 341 will not interfere and affect the rotation of the first fixed ring 310, and the arrangement of the detour passage 342 makes it possible for the air flow flowing in the air flow channel 340 not to affect the foam inlet passage 331, but instead will cause the foam inlet passage 331 to guide the foam to the foam outlet passage 333 due to the influence of negative pressure.

[0049] In one embodiment, the elastic baffle 350 includes a fixed portion 351, an arc-shaped portion 352 and a limiting portion 353. The fixed portion 351 is fixed to the side of the foam inlet 311 away from the water flow direction. One end of the arc-shaped plate is connected to the fixed portion 351, and the other end is bent to form an arc with the arc opening facing the water flow direction. The two ends of the limiting portion 353 are respectively connected to the fixed portion 351 and the end of the arc-shaped portion 352 away from the fixed portion 351, so as to limit the arc-shaped portion 352. A water-permeable hole 354 is opened on the arc-shaped portion 352.

[0050] like Figure 6 As shown, in the first state, the water flow direction is facing the inner surface of the arc portion 352, and the foam in the water flow is blocked in the arc mouth of the arc portion 352. In the second state, the water flow direction is facing the outer surface of the arc portion 352, and the foam in the water flow is pushed into the foam channel 330.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
