Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a novel short-range high-efficiency horizontal pipe sedimentation device. Background Art

[0002] In the process of sewage treatment, it is often necessary to use the principle of shallow pool sedimentation to remove the sludge in the sewage. The specific principle of the shallow pool theory is: suppose the length of the inclined tube sedimentation tank is L, the horizontal flow rate in the tank is V, and the particle settling rate is u0. Under ideal conditions, L / H = V / u0. It can be seen that when the L and V values ​​remain unchanged, the shallower the tank body, the smaller the suspended particles that can be removed. If a horizontal partition is used to divide H into 3 layers, each layer is H / 3 deep, and under the condition that u0 and v remain unchanged, only L / 3 is needed to remove u0 particles. That is, the total volume can be reduced to 1 / 3 of the original. If the pool length remains unchanged, since the pool depth is H / 3, the horizontal flow rate can be increased to 3v, and particles with a settling rate of u0 can still be removed, that is, the processing capacity is increased by 3 times. At the same time, dividing the sedimentation tank into n layers can increase the processing capacity by n times. This is the shallow pool theory proposed by Hazen in the early 20th century. The horizontal tube sedimentation separation technology applies Hazen's "shallow pool theory", places the sedimentation tube horizontally, flows horizontally, and the suspended matter settles vertically, which has the sedimentation and separation functions under the best conditions. Among them, the horizontal tube sedimentation device is often used when removing sludge from sewage using the shallow pool sedimentation principle.

[0003] The current horizontal tube sedimentation device is a non-standard part that needs to be produced at a moment's notice. The quality cannot be guaranteed due to the tight deadline. Each product is customized according to the on-site dimensions, which is labor-intensive and material-intensive (especially the installation of inclined mud slides in the rectangular outer frame - 45-60°, and the models of the two top corner inclined plates are too scattered). It is not convenient for the efficient assembly and use of the horizontal tube sedimentation device. At the same time, there is one mud slide in each row, which increases the head loss and makes the sedimentation efficiency of the horizontal tube sedimentation device relatively low.

[0012] Furthermore, the buffer cavity is formed on each of the A-type assembly units, and the buffer cavity is an inclined structure.

[0013] By adopting the above technical solution, the buffer chamber can collect the settled sludge, so that when the sludge reaches a certain amount, the sludge can be easily discharged under the action of its own weight.

[0014] Furthermore, the mud sliding port is connected to the buffer chamber and the inverted V-shaped vertical mud discharge port.

[0015] By adopting the above technical solution, the mud sliding port can ensure that the sludge settled in the buffer chamber is conveniently discharged into the inverted V-shaped vertical mud discharge port.

[0016] Furthermore, the mud discharge channel baffle is bolted to the A-type sedimentation device frame.
