Description

Technical Field

[0001] The utility model relates to the technical field of paper production, in particular to a white water precipitation device in paper production. Background Art

[0002] White water sedimentation device is a device designed for treating white water produced in the papermaking process. White water is wastewater containing fibers, fillers, colloids and some soluble organic matter produced in the papermaking process. It needs to be treated by sedimentation device to meet the recycling or discharge standards.

[0003] The process of white water sedimentation includes buffering and separation steps. The buffering step is to slow down the impact of water flow through the white water buffer device before the white water enters the sedimentation tank, making the white water flow more stable and facilitating the sedimentation of suspended matter. The separation step refers to the process in which suspended matter such as fibers and fillers in the white water gradually settle to the bottom of the tank due to gravity, while the clearer water gradually rises.

[0004] In the prior art, during the separation of white water, since the flow rate of the conical barrel installed at the bottom of the sedimentation tank is different from that in the sedimentation tank, the suspended matter will remain in the conical barrel. When white water continues to be added from the outside, the stability of the sedimentation tank will be destroyed, causing the suspended matter at the bottom to rise, resulting in the white water after sedimentation still containing suspended matter. Therefore, the present application provides a white water sedimentation device in paper production to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a white water sedimentation device in paper production to solve the problem that the conical barrel installed at the bottom of the sedimentation tank is different from the flow rate in the sedimentation tank, and the suspended matter will stay in the conical barrel. When the white water is continuously added from the outside, the stability in the sedimentation tank will be destroyed, and the suspended matter at the bottom will rise, so that the white water after sedimentation still contains the suspended matter.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a white water sedimentation device in paper production, comprising: a sedimentation tank body; a buffer part, located in the sedimentation tank body, used to mitigate the impact of water flow on the white water in the sedimentation tank body; an isolation component, installed on the buffer part, used to prevent suspended matter in the sedimentation tank body from floating to the water outlet; a rotating part, located on the sedimentation tank body, and configured to drive the buffer part to rotate so as to adjust the isolation component to be located above or below the buffer part; a driving part, located on the sedimentation tank body, used to drive the rotating part to rotate.

[0007] Preferably, the buffer part includes: two groups of fixed plates, respectively installed on opposite sides of the inner wall of the sedimentation tank body; several groups of buffer components, installed between the two groups of fixed plates and rotatably connected to the two groups of fixed plates; when the several groups of buffer components are all kept in a horizontal state, the buffer components are in contact with each other, and the outermost two groups of buffer components are in contact with the side wall of the sedimentation tank body on the side away from each other.

[0008] Preferably, the buffer assembly includes: two groups of circular grooves, which are respectively opened on a group of fixed plates, and the centers of the two groups of circular grooves are on the same horizontal line; a through groove, which is opened on the sedimentation tank body, and the through groove is connected with a group of circular grooves; a rotating rod, which is installed in the two groups of circular grooves and is rotatably connected with the two groups of circular grooves, and one side of the rotating rod passes through the through groove and extends out of the sedimentation tank body; a buffer plate, which is installed on the rotating rod and is used to mitigate the impact of water flow on white water in the sedimentation tank body.

[0009] Preferably, the isolation assembly includes: an isolation frame, which is installed on the buffer plate and is slidably connected to the buffer plate.

[0010] Preferably, it also includes: two groups of slide grooves, which are respectively opened on the opposite sides of the buffer plate; and a plurality of groups of hole grooves, which are opened on the buffer plate and are used for white water to pass through the buffer plate.

[0011] Preferably, the isolation frame comprises: two groups of slide plates, respectively installed on the buffer plates, and each group of slide plates is slidably connected to a group of slide grooves; a filter screen is installed between the two groups of slide plates to prevent the rising suspended matter from continuing to rise.

[0012] Preferably, the rotating part includes: several groups of auxiliary gears, which are installed on the sedimentation tank body, and each group of auxiliary gears is respectively connected to a group of rotating rods extending out of the sedimentation tank body; two groups of racks, which are installed on the sedimentation tank body and meshed with the several groups of auxiliary gears to drive the several groups of auxiliary gears to rotate.

[0013] Preferably, it also includes: a main gear, which is installed on the sedimentation tank body, located between the two sets of racks, meshed with both sets of racks, and connected to the output end of the driving part, for driving the two sets of racks to make opposite horizontal linear motions.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects: 1. In the above scheme, a rotating part is provided to drive the buffer part to rotate. When the buffer plate in the buffer part is tilted, the water flow at the water inlet is acted upon by the buffer plate, thereby slowing down the impact of the white water in the sedimentation tank body, thereby reducing the rise of suspended matter.

[0015] 2. By setting up the isolation component, when the buffer plate in the buffer part is under the action of the rotating part and the isolation component is located above the buffer plate, even if the water surface balance in the sedimentation tank body is broken, the suspended matter cannot continue to rise due to the obstruction of the isolation component, thereby protecting the separated white water from being contaminated by the suspended matter.

[0027] like Figures 1 to 5 As shown, the buffer part includes: two groups of fixed plates 3, which are respectively installed on opposite sides of the inner wall of the sedimentation tank body 1; several groups of buffer components, which are installed between the two groups of fixed plates 3 and rotatably connected to the two groups of fixed plates 3; when the several groups of buffer components are kept in a horizontal state, the buffer components are in contact with each other, and the outermost two groups of buffer components are in contact with the side wall of the sedimentation tank body 1 on the side away from each other.

[0028] like Figures 1 to 5 As shown, the buffer assembly includes: two groups of circular grooves 4, which are respectively opened on a group of fixed plates 3, and the centers of the two groups of circular grooves 4 are on the same horizontal line; a through groove 5, which is opened on the sedimentation tank body 1, and the through groove 5 is connected with a group of circular grooves 4; a rotating rod 6, which is installed in the two groups of circular grooves 4 and is rotatably connected with the two groups of circular grooves 4, and one side of the rotating rod 6 passes through the through groove 5 and extends out of the sedimentation tank body 1; a buffer plate 14, which is installed on the rotating rod 6 and is used to reduce the impact of water flow on the white water in the sedimentation tank body 1.

[0029] Embodiment 2: Figures 2 to 4 As shown, the isolation assembly includes: an isolation frame, which is installed on the buffer plate 14 and is slidably connected to the buffer plate 14.
