Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a solid-liquid separation filler structure for sewage treatment. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water and is a device for purifying water. A filler layer is set in the sedimentation tank to increase the contact area between the liquid and the solid particles and promote the sedimentation of suspended particles.

[0003] Most of the packings currently used are inclined plate or inclined tube type. In the process of solid-liquid separation, the solid sinks in the opposite direction of the water flow. Under the push of the water flow, the solid sinking speed slows down, the separation speed slows down, and the separation effect is weakened. The utility model proposes a packing structure that provides a separate sinking channel for solid sinking and reduces the influence of water flow impact on solid sinking. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a solid-liquid separation filler structure for sewage treatment.

[0005] The technical solution adopted by the utility model is: a solid-liquid separation filler structure for sewage treatment, comprising a fixed rod and a filler unit, wherein a plurality of groups of filler unit layers are vertically arranged on the fixed rod, and the filler unit layer comprises a plurality of horizontally arranged filler units;

[0006] Specifically, the packing unit includes a sedimentation funnel, a connecting plate and a positioning vertical plate. A connecting plate is provided on one side of the sedimentation funnel, and a hole matching with a fixing rod is opened on the connecting plate. The connecting plate is used to assemble the packing unit on the fixing rod. A plurality of positioning vertical plates are evenly arranged on the outer periphery of the lower part of the sedimentation funnel. The positioning vertical plates are used to connect the upper and lower packing units. The positioning vertical plates are adapted to the inner conical surface of the sedimentation funnel. A limiting block is provided at the lower part of the fixing rod, and the limiting block is used to fix the lowest layer of packing units.

[0007] Furthermore, the inner surface of the sedimentation funnel is provided with a slot that cooperates with the positioning vertical plate, and the slot can make the connection between the upper and lower layers of the filling units more stable;

[0008] Specifically, three positioning vertical plates are provided;

[0009] Optionally, each packing unit layer is provided with two packing units;

[0010] Optionally, each packing unit layer is provided with four packing units.

[0011] The utility model increases the contact area between solid particles and liquid by setting the working surface of the packing unit as a conical inclined surface; the packing unit is set vertically, and the outer side of the sedimentation funnel of the packing unit can block the impact of the liquid on the solid particles located on the inner side of the sedimentation funnel.

[0012] The utility model has the advantages of simple structure and convenient use, reduces the impact of upward water flow on solid particles precipitating downward, accelerates the precipitation speed and improves the precipitation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0019] Example 1

[0020] like Figure 3 As shown, a solid-liquid separation packing structure for sewage treatment includes a fixed rod 10 and a packing unit 20. A plurality of packing unit layers are vertically arranged on the fixed rod 10, and the packing unit layer includes two horizontally arranged packing units 20;

[0021] Example 2

[0022] like Figure 4 As shown, in this embodiment, four packing units 20 are arranged in the packing unit layer.

[0023] like Figure 1-Figure 4As shown, the packing unit 20 of the above two embodiments includes a sedimentation funnel 21, a connecting plate 22 and a positioning vertical plate 23. A connecting plate 22 is provided on one side of the sedimentation funnel 21. A hole that matches the fixing rod 10 is opened on the connecting plate 22. The connecting plate 22 is used to assemble the packing unit 20 on the fixing rod 10. Three positioning vertical plates 23 are evenly arranged on the outer periphery of the middle and lower part of the sedimentation funnel 21. The positioning vertical plates 23 are used to connect the upper and lower packing units 20. The positioning vertical plates 23 are aligned with the inner conical surface of the sedimentation funnel 21. The inner surface of the sedimentation funnel 21 is provided with a slot 24 that cooperates with the positioning vertical plate 23. A limit block 11 is provided at the lower part of the fixing rod 10. The limit block 11 is used to fix the lowest layer of filling units 20. During installation, the fixing rod 10 is vertically fixed to the bottom of the sedimentation tank, and the number of filling units 20 in each layer of the filling unit layer is determined. The hole on the connecting plate 22 of the filling unit 20 to be installed is put on the fixing rod 10, and the upper positioning plate is inserted into the slot 24 of the sedimentation funnel 21 of the lower filling unit 20.

[0024] Working principle: When in use, a packing layer for solid-liquid separation is composed of multiple structures of the utility model. The sewage mixed with solid particles moves upward from the bottom of the packing layer, and then the solid particles fall under the action of gravity. The solid particles fall onto the sedimentation funnel 21 of the packing unit 20 and move downward along the conical inner surface of the sedimentation funnel 21. The sewage moving upward under the sedimentation funnel 21 is shielded by the sedimentation funnel 21, which reduces the impact on the falling solid particles. The solid particles fall from the upper packing unit 20 into the lower packing unit 20, and finally fall to the bottom of the sedimentation tank.

[0025] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
