Description

Secondary reflecting plate device of secondary sedimentation tank

Technical Field

The utility model belongs to the sewage treatment field relates to the sedimentation tank, especially a two heavy pond two-stage reflecting plate device.

Background

The sedimentation tank is a structure for removing suspended matters in water by using sedimentation. Sedimentation tanks are widely used in wastewater treatment. The type of the device is various, and the device can be divided into a horizontal flow type, a vertical flow type and a radial flow type according to the water flow direction in the pool. The sedimentation tank is generally a structure for separating sludge and water before or after biochemistry, and most of the sedimentation tank is sludge with finer separated particles. The sedimentation tank before the biochemical treatment is called a primary sedimentation tank, and the sedimentation tank after the biochemical treatment is generally called a secondary sedimentation tank. The secondary sedimentation tank is used for separating mud and water, clarifying the mixed solution, concentrating the sludge and returning the separated sludge to the biological treatment section. The quality of the effect directly influences the quality of the effluent and the concentration of the return sludge. The traditional secondary sedimentation tank only has a primary reflection plate, and a water inlet is directly extended into a central cylinder, so that the flow rate of wastewater is not fully buffered, and if the flow of wastewater fluctuates, sedimentation and concentration effects are not good, activated sludge suspended matters can be added into effluent, so that the BOD (biochemical oxygen demand) mass concentration of the effluent is increased; meanwhile, the concentration of the returned sludge is reduced, so that the concentration of mixed liquid in the aeration tank is reduced, and the purification effect is influenced.

The utility model provides a technical scheme that technical problem adopted is:

a secondary reflecting plate device of a secondary sedimentation tank comprises a center barrel, a conical barrel, a primary reflecting plate and a secondary reflecting plate, wherein the top of the center barrel is fixedly arranged on the inner wall of the top surface of the secondary sedimentation tank, the bottom of the center barrel is coaxially welded with the small end of the conical barrel, a plurality of primary suspension parts are radially and symmetrically welded at the large end of the conical barrel, the lower end of each primary suspension part is fixedly connected with the primary reflecting plate, a water inlet pipe penetrates into the center barrel, a plurality of secondary suspension parts are radially and symmetrically welded on the outer wall of the pipe orifice of the water inlet pipe in the center barrel, and the upper end of each secondary suspension part is fixedly connected with the secondary reflecting plate.

Moreover, the first-stage reflecting plate is of a conical structure, and the second-stage reflecting plate is of an inverted conical structure.

Moreover, the first-stage suspension piece is an angle iron, and the second-stage suspension piece is a flat iron.

And the upper end and the lower end of the first-level suspension piece are both made into beveled edges, the upper end of the first-level suspension piece is fully welded with the cone, and the lower end of the first-level suspension piece is fully welded with the first-level reflecting plate.

And, the second grade suspends the piece upper end and the lower extreme and all makes the bevel connection, and the second grade suspends the upper end of piece and second grade reflecting plate full weld, and second grade suspends the piece lower extreme and inlet tube mouth of pipe full weld.

The utility model has the advantages that:

the utility model discloses a two-stage reflecting plate effectively subducts the kinetic energy of intaking, and the rivers impact that gets into two heavy ponds that subduct that can be more make two heavy pond interior muddy water flow more tend to steadily, improve the mud-water separation effect, satisfy the flow and strike the operating mode, guarantee the effect of going out water simultaneously.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

A secondary reflecting plate device of a secondary sedimentation tank comprises a central cylinder 2, a conical cylinder 11, a primary reflecting plate 8 and a secondary reflecting plate 4, wherein a mud scraper 3 is fixedly arranged at the center of the top 1 of the secondary sedimentation tank, a mud scraper shaft 10 sequentially penetrates through the central cylinder, the conical cylinder and the primary reflecting plate and then fixedly arranged with a mud scraper 9 at the bottom of the secondary sedimentation tank, the top of the central cylinder is fixedly arranged on the inner wall of the top surface of the secondary sedimentation tank, the bottom of the central cylinder is coaxially welded with the small-mouth end of the conical cylinder, a plurality of primary suspension pieces 7 are radially and symmetrically welded at the large-mouth end of the conical cylinder, and the lower end of each primary suspension piece is fixedly connected with the primary reflecting plate. The water inlet pipe 6 penetrates into the central cylinder, a plurality of secondary suspension pieces 5 are symmetrically welded on the outer wall of the pipe orifice of the water inlet pipe in the central cylinder in the radial direction, and the upper ends of the secondary suspension pieces are fixedly connected with the secondary reflecting plate.

The first-level reflecting plate is of a conical structure, and the second-level reflecting plate is of an inverted conical structure.

The first-stage suspension piece is made of angle iron, and the second-stage suspension piece is made of flat iron.

The upper end and the lower extreme of one-level piece of suspending are all made the bevel connection, and the upper end and the awl section of thick bamboo full weld of one-level piece of suspending are suspended in midair, and one-level piece lower extreme and one-level reflecting plate full weld are suspended in midair.
