Description

[0002] The wastewater generated during the winemaking process needs to undergo subsequent treatment before it can be discharged or recycled. During the initial treatment of the winemaking wastewater, it needs to be screened through a filter to remove large particles of impurities and residual winemaking raw materials, and then flocculants are added for precipitation. The supernatant is discharged or recycled, and the lower layer of wastewater and flocs are collected and treated. However, the precipitation of flocs itself takes a long time. At the same time, the sugar content of winemaking wastewater is relatively high, which leads to a higher viscosity of the wastewater.

[0019] It also includes a receiving plate 110, a cover plate 111, an elastic cloth 112, a third filter screen 113 and a top plate 114; a sewage pipe is arranged on the front side of the sedimentation tank 2; an openable rotating plate is arranged on the front side of the sedimentation tank 2; the receiving plate 110 is connected to the baffle 104 through a spring; an elastic cloth 112 is fixedly connected between each receiving plate 110 and the baffle 104; two holes are provided on each receiving plate 110; a cover plate 111 is slidably connected to the hole of each receiving plate 110; a third filter screen 113 is detachably connected to the inner side of the sedimentation tank 2, and the third filter screen 113 is located on the lower side of the baffle 104; a number of top plates 114 are fixedly connected to the inner side of the sedimentation tank 2; each top plate 114 is located directly below the adjacent cover plate 111.

[0020] The upper side of each receiving plate 110 is arched.

[0021] The portion of the pressing plate 103 that is in contact with the second filter screen 6 is configured to be in an arc shape that bulges downward.

[0022] A plurality of guide portions 10401 are disposed on the upper side of the baffle 104; each guide portion 10401 is configured to be inclined with a high middle portion and low sides.

[0023] Each first filter screen 5 is configured to be concave downward in the middle.

[0024] The baffle 104 is entirely coated with a hydrophobic coating, which prevents flocs from adhering to the surface of the baffle 104 under the action of the flow of water, thereby preventing the flocs from affecting subsequent wastewater sedimentation.

[0025] Before treating the brewing wastewater, the workers first pour the wastewater into the sedimentation tank 2 through an external conveying pipe, and then add flocculants into the conveying pipe, and pour the flocculants into the wastewater to make it precipitate. After the precipitation, the wastewater forms a supernatant and a lower layer of wastewater. Finally, the workers discharge the supernatant for recycling, and the lower layer of wastewater is discharged after the flocs are cleaned. Since the sugar content of the brewing wastewater is relatively high, the brewing wastewater is viscous as a whole. During the flocculation and sedimentation process, the flocs in the wastewater are affected by the viscous wastewater, resulting in a prolonged sedimentation time of the flocs, which affects the overall treatment efficiency of the wastewater. Therefore, after the flocculant has been added to react for a period of time, the worker starts the first electric push rod 101 to push The movable fixed frame 4, the first filter screen 5 and the second filter screen 6 move downward together and are immersed in the sedimentation tank 2, that is, immersed in the wastewater. Then, under the push of the first electric push rod 101, the first filter screen 5 and the second filter screen 6 continue to move downward, so that the flocculated wastewater can pass through the first filter screen 5 and the second filter screen 6 normally, while the flocs cannot pass through. Then, the first filter screen 5 and the second filter screen 6 in the descending process drive the flocs to move downward together. In this process, the flocs floating in the wastewater are quickly precipitated by actively pressing down the first filter screen 5 and the second filter screen 6, thereby improving the efficiency of the equipment for wastewater treatment. At the same time, the impurities floating in the supernatant are pressed into the lower layer of wastewater together, thereby reducing the subsequent treatment steps for the supernatant.

[0026] In the process of accelerating the sedimentation of flocs by using the first filter screen 5 and the second filter screen 6, considering that the flocculated wastewater permeates the first filter screen 5 and the second filter screen 6 from bottom to top, the flocs are easily pressed on the lower sides of the first filter screen 5 and the second filter screen 6 during the infiltration of the wastewater, resulting in the blockage of the first filter screen 5 and the second filter screen 6, making it difficult for the wastewater to pass through. Therefore, when the wastewater passes through the second filter screen 6, since the second filter screen 6 is made of elastic material, the middle part of the second filter screen 6 is pressed to be concave upward, and then cooperates with the downward concave middle part of the first filter screen 5 to form a wave shape as a whole, so that the flocs are more likely to accumulate in the upward concave area of ​​the second filter screen 6. At the same time, due to the water permeability effect of the second filter screen 6 It is higher than the first filter screen 5, so that the resistance of wastewater passing through the second filter screen 6 is smaller, so that most of the wastewater penetrates from the second filter screen 6, and a small part of the wastewater penetrates from the first filter screen 5, so that a pressure difference is formed between the first filter screen 5 and the second filter screen 6, the flow rate in the second filter screen 6 area is fast and the pressure is small, and the flow rate in the first filter screen 5 area is slow and the pressure is large, so that the flocs flow to the area with smaller pressure, that is, flow to the second filter screen 6, while the first filter screen 5 is normally permeable, without affecting the infiltration of wastewater, avoiding blockage in the process of pressing down the flocs, and at the same time, the flocs can be gathered on the lower side of the second filter screen 6, which is convenient for subsequent centralized cleaning, thereby improving the equipment's wastewater treatment effect.

[0027] It is also considered that after the wastewater is precipitated, workers are required to clean the flocs on the second filter screen 6 and the sedimentation tank 2 to prevent the flocs from remaining and affecting the next wastewater precipitation. The conventional cleaning method not only increases labor costs, but also requires the equipment to be stopped, resulting in low efficiency of the entire process. Therefore, when the flocs are completely precipitated, the worker starts the second electric push rod 102 to push the pressure plate 103 downward into the wastewater. It should be noted that after the flocs are completely precipitated, the first filter screen 5 and the second filter screen 6 are never in contact with the upper side of the baffle 104. At the same time, the length and width of the pressure plate 103 are both smaller than the length and width of the sedimentation tank 2. In the process of the pressure plate 103 being immersed in the wastewater, the pressure plate 103 drives the extrusion rod 108 to move downward, so that the pressure plate 103 does not touch the fixed frame 4, the extrusion rod 108 first contacts the upper side of the receiving plate 110, and then pushes the receiving plate 110 to move downward, thereby compressing the spring between the receiving plate 110 and the sedimentation tank 2, and then stretching the elastic cloth 112, so that the space formed by the baffle 104, the receiving plate 110 and the elastic cloth 112 gradually increases, thereby forming a negative pressure between the receiving plate 110 and the elastic cloth 112, and the floccules adhering to the lower side of the second filter screen 6 are drawn toward the receiving plate 110 under the action of the negative pressure, so that the floccules on the second filter screen 6 are separated. At the same time, under the action of the negative pressure, since the pressing plate 103 has not yet contacted the fixing frame 4 at this time, part of the supernatant liquid penetrates downward through the second filter screen 6 under the influence of the negative pressure, and then part of the supernatant liquid is used to recoil the second filter screen 6, further The cleaning effect of the second filter screen 6 is further improved, so that the floccules fall completely on the receiving plate 110 and the baffle 104, and the first filter screen 5 and the second filter screen 6 are cleaned. At the same time, when the pressing plate 103 contacts the fixed frame 4, the part of the pressing plate 103 that is attached to the second filter screen 6 is set to a downwardly convex arc shape, so that the second filter screen 6 is compressed, and the middle part bulges downward and unfolds, so that the adhered floccules are easier to detach. At the same time, the pressing plate 103 cooperates with the fixed frame 4 to separate the sedimentation tank 2 into two layers, the supernatant is located above the fixed frame 4 and the pressing plate 103, and the lower layer of wastewater is located below the fixed frame 4 and the pressing plate 103. At this time, the first electric push rod 101 and the second electric push rod 102 continue to extend downward synchronously, so that the fixed frame 4 and the pressing plate 103 move downward synchronously. , and because the cover plate 111 is tightly closed on the receiving plate 110 under the action of water pressure, when the pressure plate 103 continues to push the receiving plate 110 to move downward, the cover plate 111 contacts the top plate 114 and cannot move downward any further, and is then lifted up by the top plate 114, thereby opening the hole opened on the receiving plate 110, and then the lower layer of wastewater and flocs flow from the hole to the third filter screen 113, and under the action of the third filter screen 113, the wastewater flows into the first collecting tank 3, while the flocs remain on the third filter screen 113, that is, the wastewater and flocs in the sedimentation tank 2 are all discharged, and subsequently the sewage pipe on the front side of the first collecting tank 3 can be opened, and then the wastewater can be discharged as required, and the treatment of the flocs only requires the worker to open the rotating plate on the front side of the sedimentation tank 2 after the work is completed,Then the third filter screen 113 is pulled out, and the flocs on the third filter screen 113 are rinsed without shutting down the equipment for cleaning. At the same time, the flocs remaining on the second filter screen 6 are cleaned to achieve self-cleaning of the equipment. Furthermore, the guide part 10401, in cooperation with the flow of wastewater, guides the flocs remaining in the sedimentation tank 2 to the third filter screen 113 to prevent the flocs remaining in the sedimentation tank 2 from affecting the subsequent wastewater sedimentation.

[0028] Example 2 Based on Example 1, Figure 1 and Figure 6 As shown, it also includes a separation tank 105, a connecting pipe 106, a second collecting tank 107, a sealing plate 109 and a third electric push rod 115; the separation tank 105 is fixedly connected to the outside of the sedimentation tank 2; a plurality of connecting pipes 106 are connected to the lower side of the separation tank 105; two second collecting tanks 107 are fixedly connected to the lower side of the fixed frame 1; a plurality of third electric push rods 115 are fixedly connected to the left and right sides of the sedimentation tank 2; the telescopic ends of the third electric push rods 115 on the same side are commonly fixedly connected to a sealing plate 109; overflow grooves are opened on the left and right sides of the sedimentation tank 2, and each sealing plate 109 blocks the adjacent overflow grooves.

[0029] Two guide parts 10501 are arranged in the separation tank 105 . The guide parts 10501 are arranged to be inclined downward, and the connecting pipe 106 is located at the lowest point of the guide parts 10501 .

[0030] When the discharge of wastewater and flocs is completed, the first electric push rod 101 and the second electric push rod 102 are controlled to reset synchronously, thereby driving the fixed frame 4 and the pressure plate 103 to reset upward, and at the same time starting the contraction of the third outer electric push rod 115, thereby lifting the sealing plate 109, thereby opening the overflow troughs on the left and right sides of the sedimentation tank 2, so that the liquid level of the supernatant gradually rises under the lifting action of the fixed frame 4 and the pressure plate 103, so that the supernatant flows out of the overflow trough and flows to the separation tank 105, and then flows to the connecting pipe 106 under the guidance of the guide part 10501, to prevent the supernatant from remaining in the separation tank 105, and finally the supernatant is collected in the second collecting tank 107, that is, the supernatant is collected during the resetting process of the fixed frame 4 and the pressure plate 103, so that the treatment of wastewater is more efficient.
