Description

Technical Field

[0002] Decorative paper is an indispensable raw material in building materials. It is placed under the surface paper in the product structure. It mainly provides decorative patterns and covers the bottom glue to prevent it from seeping through. The production and processing of decorative paper involves the entire process from pulping to paper forming. During this stage, a large amount of sewage will be generated. If papermaking sewage is discharged into rivers without effective treatment, it will cause serious pollution to the water body, affect the survival of aquatic organisms, destroy the ecological balance, and threaten the health of coastal residents. Therefore, sewage treatment is crucial to protecting the environment.

[0003] Common sewage treatment methods are divided into physical, chemical and biological methods. The physical method is mainly to remove suspended solid pollutants in sewage, and the sedimentation tank is a common equipment for sewage treatment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0022] Embodiment 1, a sedimentation tank for treating wastewater from decorative paper processing, such as Figure 1 -picture, Figure 5, including a sedimentation tank body 11, a plurality of connecting blocks 12 are fixedly connected to the inner bottom end of the sedimentation tank body 11, and the connecting blocks 12 are arranged in a horizontal array, and a space gap is provided between two adjacent connecting blocks 12, and the space gap is called a sludge hopper, specifically, the cross-sectional shape of the connecting blocks 12 located on the far left and the far right is a right-angled trapezoid, and the cross-sectional shape of the remaining connecting blocks 12 is an isosceles triangle, and the cross-sectional shape of the sludge hopper is an isosceles trapezoid that is wide at the top and narrow at the bottom. The shape of the sludge hopper is set by using the shape of the connecting blocks 12, so that the sludge hopper can better receive the settled suspended matter, so that the suspended matter can be deposited at the bottom of the sludge hopper, and the number of sludge hoppers is an even number, and the front, A sewage pipe 13 is fixedly connected between the rear walls and is located inside the sludge hopper. The sewage pipe 13 can suck the suspended matter accumulated in the sludge hopper and clean the sludge hopper to ensure that the sludge hopper can be used continuously. An inlet pipe 14 is fixedly connected to the left wall of the sedimentation tank body 11, and sewage can be discharged into the sedimentation tank body 11. An outlet pipe 15 is fixedly connected to the right wall of the sedimentation tank body 11, and the height of the outlet pipe 15 is higher than that of the inlet pipe 14, so that the sewage that has been settled in the sedimentation tank body 11 can be discharged. In summary, the sedimentation tank body 11, the connecting block 12, the sewage pipe 13, the inlet pipe 14 and the outlet pipe 15 constitute a working mechanism 1, which is used to provide a working space for sewage treatment.

[0023] like Figure 1-Figure 2 , Figure 6 A rectifying mechanism 2 is movably connected inside the sedimentation tank body 11 above the sludge hopper, and is used to rectify the flowing sewage to reduce sewage turbulence.

[0024] like Figure 1-Figure 2 , Figure 6-Figure 7 The movable mechanism 3 includes a left partition 31 and a right partition 32, and the left partition 31 is located on the left side of the rectifying mechanism 2, and the right partition 32 is located on the right side of the rectifying mechanism 2. The left partition 31 and the right partition 32 are symmetrically arranged, and the left partition 31 and the right partition 32 are both composed of a rotating component 4 and a fixed component 5, which are used to close the sludge hopper to prevent suspended matter from floating around during cleaning.

[0025] like Figure 2-Figure 4 , Figure 10-12 The rotating assembly 4 includes a rotating rod 41 and a rotating gear 42. The two ends of the rotating rod 41 are movably connected to the front and rear walls of the sedimentation tank body 11 respectively. One end of the rotating rod 41 is fixedly connected to the rotating gear 42, and the rotating gear 42 is located outside the sedimentation tank body 11. The rotating gear 42 can cooperate with the pushing mechanism 6 to drive the rotating rod 41 to rotate, so that the rotating rod 41 drives the fixed assembly 5 to deflect to achieve different functions in different states.

[0026] like Figure 2-Figure 4 , Figure 10-12The fixing assembly 5 includes a fixing plate 51 and a fixing pad 52. One end of the fixing plate 51 is fixedly connected to the outer wall of the rotating rod 41. When the sludge hopper is opened, the fixing plate 51 is in a vertical state, and the fixing plate 51 is in contact with the rectifying mechanism 2. When the sludge hopper is closed, the fixing plate 51 is in an inclined state, and the fixing plate 51 is in contact with the connecting block 12. The inclination of the fixing plate 51 is the same as that of the connecting block 12, and the two can form the same inclined surface, which is convenient for the suspension to settle in the sludge hopper. In summary, the fixing plate 51 can produce two different effects on the sludge hopper. For the fixing plate 51 that closes the sludge hopper, it can not only prevent the sludge from being sludged, but also prevent the sludge from being sludged. When the bucket is cleaned, the suspended matter floats around, which improves the sewage treatment effect. At this time, it can also push the suspended matter to settle in the adjacent sludge bucket, thereby improving the sewage treatment efficiency. For the fixed plate 51 for opening the sludge bucket, it can not only open the sludge bucket to settle the suspended matter, but also block some of the perforations on the rectifying mechanism 2, so that the sewage movement speed is reduced, and the residence time of the sewage above the sludge bucket is prolonged, so that the suspended matter can be fully settled in the sludge bucket, thereby improving the sewage treatment effect. The other end of the fixed plate 51 is fixedly connected with a fixed pad 52, and the setting of the fixed pad 52 can make the fixed component 5 fully contact with the connecting block 12.

[0027] like Figure 1 and Figure 6 , a pushing mechanism 6 is provided on the front and rear sides of the working mechanism 1, and the pushing mechanism 6 is in contact with the movable mechanism 3 to provide power for the work of the movable mechanism 3. The number of the pushing mechanisms 6 is two, and the pushing mechanisms 6 are located on the front and rear sides of the sedimentation tank body 11. The pushing mechanism 6 includes a pushing pump 61, a pushing plate 62 and a supporting seat 63, as shown in FIG. Fig.13 The push pump 61 is located on the left side of the sedimentation tank body 11, and the push pump 61 is movably connected to one end of the push plate 62. One push mechanism 6 is correspondingly provided with two support seats 63, and one support seat 63 is located below the push pump 61, and the other support seat 63 is movably connected to the other end of the push plate 62. When the push pump 61 is started, the push plate 62 can be pushed to move smoothly along the support seat 63.

[0028] Embodiment 2, based on embodiment 1, as Figure 2-Figure 4 , Figure 10-12The fixing assembly 5 also includes a fixing capsule 53 and a moving member 54. A fixing hole is provided on the wall surface of the fixing plate 51, and the fixing plate 51 is fixedly sleeved with the fixing capsule 53 through the fixing hole. The interior of the fixing capsule 53 is filled with a solution. The solution is moved by an external force to deform the fixing capsule 53 located in the fixing hole, thereby facilitating the cleaning of suspended matter attached to the surface of the fixing plate 51. A card slot is provided on one side of the fixing plate 51, and the fixing plate 51 is movably connected to the moving member 54 through the card slot. The moving member 54 is located on the side of the fixing plate 51 away from the rectifying mechanism 2 when the fixing plate 51 is in a vertical state. Therefore, when the fixing plate 51 is in a vertical state, the moving member 54 is located near the rotating rod 41 due to the action of gravity. When the fixing plate 51 is in an inclined state, the moving member 54 is located near the rotating rod 41 due to the action of gravity. When in the inclined state, the movable member 54 is located near the fixed pad 52 due to the action of gravity, so that when the fixed plate 51 changes its state, the movable member 54 can move along the side wall of the fixed plate 51 to effectively clean the side wall of the fixed plate 51. At the same time, if the fixed plate 51 is in the inclined state, the movable member 54 is located below the fixed plate 51, and one end of the fixed capsule 53 close to the movable member 54 protrudes from the surface of the fixed capsule 53, while the other end of the fixed capsule 53 is level with the surface of the fixed plate 51, thereby facilitating the downward movement of suspended matter along the surface of the fixed plate 51. If the movable member 54 moves subsequently, it will apply an extruding force to one end of the fixed capsule 53, thereby making the other end of the fixed capsule 53 protrude, which is convenient for vibrating the fixed plate 51 to further clean the suspended matter.

[0029] Embodiment 3, based on embodiment 2, Figure 2-Figure 4 , Figure 8-Figure 9The rectifying mechanism 2 includes a rectifying member 21 and a rectifying plate 22. The front and rear walls of the sedimentation tank body 11 are provided with vertical grooves, and the sedimentation tank body 11 is movably connected with the rectifying member 21 through the vertical grooves, so that the rectifying member 21 can be flexibly installed on the sedimentation tank body 11, which is convenient for replacement. The rectifying member 21 is located directly above the sewage pipe 13, and the bottom end of the rectifying member 21 contacts the top end of the sewage pipe 13, so that the rectifying member 21 can fully rectify the sewage inside the sedimentation tank body 11. The side wall of the rectifying member 21 is provided with a transverse groove, and the transverse groove is connected with the rectifying cavity. The rectifying member 2 The horizontal groove is movably connected with the rotating rod 41, so that the rotating rod 41 can be restricted by the rectifying piece 21 when rotating, thereby improving the rotation stability of the rotating rod 41. The wall surface of the rectifying piece 21 is provided with an outer hole, and the outer hole is in the shape of a trumpet with narrow left and wide right. The outer hole of the rectifying piece 21 is located above the horizontal groove of the rectifying piece 21, so that the sewage can only flow away from the top of the rotating rod 41 without affecting the sludge bucket, which is conducive to the sedimentation of suspended matter. The bottom end of the rectifying piece 21 is provided with a rectifying cavity, and the rectifying piece 21 is movably connected with the rectifying plate 22 through the rectifying cavity. The rectifying plate 22 The shape is T-shaped, and the top two sides of the rectifying plate 22 are connected to the inner wall of the rectifying cavity of the rectifying member 21 by springs. The springs can be used to provide elastic force for pushing the rectifying plate 22 to be located in the upper half of the rectifying cavity. The wall surface of the rectifying plate 22 is provided with inner holes, and the inner holes are in the shape of a trumpet with narrow left and wide right. The number of rows of inner holes is one more than the number of rows of outer holes, and the inner holes and the outer holes together constitute a perforation. When the rectifying plate 22 is located in the upper half of the rectifying member 21, except for the inner holes in the top row, the remaining inner holes on the rectifying plate 22 correspond to the outer holes on the rectifying member 21 one by one to form Perforations are provided to rectify sewage. When the rectifying plate 22 is located in the lower half of the rectifying member 21, except for the inner holes in the bottom row, the remaining inner holes on the rectifying plate 22 correspond to the outer holes on the rectifying member 21 one by one to form perforations to rectify sewage. Short-bristle brushes are provided on the left and right walls of the rectifying cavity of the rectifying member 21, and short-bristle brushes are provided on the left and right walls of the rectifying plate 22. When the rectifying plate 22 moves in the rectifying member 21, the rectifying member 21 and the rectifying plate 22 can clean each other to prevent the inner holes and the outer holes from being blocked, thereby improving the durability of the rectifying mechanism 2.

[0030] like Fig.10 , Fig.12 , Fig.13 The rotating assembly 4 also includes a tooth block 43, and the outer wall of the rotating rod 41 located inside the sedimentation tank body 11 is fixedly connected with the tooth block 43, and the tooth block 43 occupies three quarters of the rotation of the rotating rod 41, that is, the tooth block 43 is located on the outer wall of the rotating rod 41 that is not connected to the fixed assembly 5. Figure 8 , Fig. 9The left and right walls of the rectifier plate 22 are both provided with vertical tooth grooves, and the rectifier plate 22 is meshed with the tooth block 43 through the vertical tooth grooves. When the rotating rod 41 rotates, the tooth block 43 rotates synchronously, thereby pushing the rectifier plate 22 to move back and forth in the rectifier cavity of the rectifier 21.

[0031] Embodiment 4, based on embodiment 3, Figure 2 , Figure 6 The movable mechanism 3 is divided into a first movable part 3a and a second movable part 3b, and the first movable part 3a and the second movable part 3b are arranged alternately. One sludge hopper corresponds to one first movable part 3a or second movable part 3b, and the states of the first movable part 3a and the second movable part 3b are opposite, that is, when the first movable part 3a closes the sludge hopper, the second movable part 3b opens the sludge hopper adjacent to the sludge hopper, thereby ensuring that there is always a sludge hopper to settle the suspended matter, and the sludge hoppers work alternately, which can reduce the working pressure and ensure more adequate sewage treatment.

[0032] like Figure 2 , Figure 6 , Fig.13 , the left partition 31 located in the first movable part 3a and the right partition 32 located in the second movable part 3b are controlled by the same pushing mechanism 6, and the right partition 32 located in the first movable part 3a and the left partition 31 located in the second movable part 3b are controlled by the same pushing mechanism 6, and the two pushing mechanisms 6 have opposite actions, that is, one pushing pump 61 pushes the pushing plate 62 to extend, and the other pushing pump 61 pushes the pushing plate 62 to retract, thereby controlling the two pushing plates 62 to move in opposite directions, and a plurality of groups of transverse tooth grooves are provided at the top of the pushing plate 62, and the pushing plate 62 is meshed with the rotating gear 42 through the transverse tooth grooves, so that the pushing plate 62 can drive the rotating gear 42 and its components to rotate when moving horizontally, thereby realizing the deflection of the fixed component 5. In summary, when the two pushing mechanisms 6 are started, the first movable part 3a and the second movable part 3b can be controlled to rotate, so that the sludge bucket in the sedimentation tank body 11 is alternately opened and closed.

[0033] The working principle of the method of the present invention is as follows: When the working mechanism 1 performs sewage treatment, the sewage is first discharged into the sedimentation tank body 11 through the water inlet pipe 14, and then the sewage moves from left to right in the sedimentation tank body 11. In this process, the sewage passes through the perforations of the rectifying mechanism 2 for rectification, and the suspended matter in the sewage is continuously settled into the sludge hopper of the sedimentation tank body 11 by gravity, and finally the treated sewage is discharged through the outlet pipe 15. When there are too many suspended matters accumulated in a sludge hopper, the two push pumps 61 are started to make the two push plates 62 move horizontally in opposite directions, thereby driving the rotating component 4 to rotate, and then driving the fixed component 5 to deflect downward, so that the two fixed components 5 are at an angle. shape, and contacts with the wall surface of the connecting block 12, that is, the top of the sludge hopper to be cleaned is closed, and the sewage discharge pipe 13 in the sludge hopper can be started at this time to suction and clean the suspended matter in the sludge hopper. It should be noted that since the first movable member 3a and the second movable member 3b are alternately arranged, and the states of the first movable member 3a and the second movable member 3b are opposite, the top of the sludge hopper adjacent to this sludge hopper is opened. Therefore, the coordinated use of the two fixing components 5 and the two connecting blocks 12 can not only effectively prevent the suspended matter from floating around when the sludge hopper is cleaned, thereby improving the sewage treatment effect, but also effectively promote the suspended matter to settle in the adjacent sludge hopper, thereby improving the sewage treatment efficiency.

[0034] When the sludge hopper needs to be opened to receive suspended matter, the two push pumps 61 are started so that the two push plates 62 push the rotating assembly 4 to rotate in the opposite direction, thereby driving the fixed assembly 5 to deflect upward, so that the two fixed assemblies 5 are in a vertical state and fit with the wall surface of the rectifying mechanism 2, that is, the top of the sludge hopper is opened, and the settled suspended matter can be fully collected. When the fixed assembly 5 remains in a vertical state, the fixed assembly 5 will block some of the perforations on the rectifying mechanism 2, so that the sewage movement speed is reduced, the residence time of the sewage above the sludge hopper is prolonged, and the suspended matter is fully settled in the sludge hopper, thereby improving the sewage treatment effect.

[0035] During the rotation of the rotating component 4, due to the engagement of the tooth block 43 with the vertical tooth groove of the rectifier plate 22, the rotating component 4 pushes the rectifier plate 22 to move up and down in the rectifier 21, thereby fully cleaning the perforations on the rectifier mechanism 2, preventing the perforations from being blocked, enhancing the continuous rectification ability of the rectifier mechanism 2, and effectively reducing the turbulence during sewage movement to reduce the impact on the sedimentation of suspended matter. At the same time, due to the deflection of the fixed component 5, the moving part 54 will move on the fixed plate 51 to clean one side of the wall of the fixed plate 51. At the same time, the moving part 54 will produce an extrusion effect on the fixed capsule 53, so that the fixed capsule 53 is deformed and continuously vibrated, thereby cleaning the other side of the wall of the fixed plate 51, thereby cleaning the suspended matter on the fixed component 5, and preventing the timely cleaning of the suspended matter in the sedimentation tank body 11 from being affected.

[0036] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
