Description

Technical Field

[0001] The utility model relates to the technical field of phosphorus-containing water treatment, in particular to an explosion device for reducing material reaction time. Background Art

[0002] Sewage treatment plants typically treat phosphorus-containing water by adding an appropriate amount of lime. After a full reaction, calcium phosphate is produced, reducing or eliminating the phosphorus ion content in the water. The full reaction between the phosphorus-containing water and the lime takes time; under normal circumstances, four hours of stirring are required to eliminate 80% of the phosphorus ions. This long reaction time results in low production efficiency. Utility Model Content

[0003] The utility model provides an aeration device capable of reducing the reaction time of materials, aiming to solve the problem of low efficiency in treating phosphorus-containing wastewater by reacting phosphorus-containing water with lime.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A gas explosion device for reducing the reaction time of materials includes an annular tube arranged in a reaction tank, the annular tube is sealed and connected to an external air source through a vent pipe, a plurality of aeration holes are provided on the annular tube at equal intervals around the axis, and corresponding sealing covers are provided at the aeration holes. The sealing covers are all hinged with the annular tube through a rebound hinge mechanism to form a rebound hinge, and the sealing covers and the corresponding aeration holes form a releasable sealing fit, and a filter plate is provided in the aeration hole.

[0006] Preferably, the sealing cover includes an arc-shaped top cover, which fits the outer wall of the annular tube at the corresponding aeration hole. One side of the arc-shaped top cover forms a rebound hinged fit with the annular tube through a rebound hinge mechanism. A sealing column is provided at the bottom of the arc-shaped top cover, which forms a sealing fit with the corresponding aeration hole.

[0007] As a more preferred embodiment, the arc-shaped top cover is concentric and coaxial with the corresponding aeration hole, and the blocking column is concentric and coaxial with the corresponding arc-shaped top cover.

[0008] Furthermore, a sealing ring is coaxially and concentrically embedded in the aeration hole located at the top of the filter plate, and a blocking column is embedded in the sealing ring to form a blocking fit.

[0009] Furthermore, the bottom of the blocking column does not contact the filter plate.

[0010] Specifically, the rebound hinge mechanism includes an extension block horizontally arranged on one side of the arc-shaped top cover. The extension block is radially parallel to the corresponding aeration hole. Both ends of the extension block are hingedly matched with the annular tube through hinges. The hinges are symmetrically arranged about the extension block. Torsion springs are provided between the two ends of the extension block and the corresponding hinges.

[0011] More specifically, the ventilation pipe is arranged along the radial direction of the annular pipe, and the ventilation pipe and the annular pipe are integrally formed and communicated with each other.

[0012] In detail, the vent pipe is sealed and passes through the reaction pool and is in sealed communication with an external gas source. An air inlet one-way valve and a pressure gauge are sequentially provided on the portion of the vent pipe located outside the reaction pool along the ventilation direction.

[0013] Beneficial effects of the utility model:

[0014] 1. The device sets aeration holes on the annular tube and provides each aeration hole with an elastically openable and closing sealing cover. When compressed air is provided by aeration, the sealing cover is opened, providing aeration conditions for the reaction and accelerating the reaction efficiency. When the reaction stops, the sealing cover automatically closes through the rebound hinge mechanism to complete the sealing. It is easy to install, improves the reaction efficiency, and closes automatically.

[0015] 2. The device uses a filter plate to prevent the calcium phosphate generated by the reaction from entering the aeration device. The calcium phosphate is blocked by the filter plate and temporarily stored in the aeration hole after being blocked. During the next aeration, it is flushed out by compressed air to complete the cleaning, and the cleaning is automatic to prevent blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As follows, embodiments are further described with reference to the accompanying drawings.

[0025] like Figures 1 to 4As shown, as a preferred embodiment 1, an aeration device for reducing the reaction time of materials includes an annular tube 1 arranged in a reaction tank, the annular tube 1 is sealed and connected to an external air source through a vent pipe 7, a plurality of aeration holes 2 are provided on the annular tube 1 at equal intervals around the axis, the aeration holes 2 are all provided with corresponding sealing covers 3, the sealing covers 3 are all formed with the annular tube 1 through a rebound hinge mechanism 4 to form a rebound hinge cooperation, and the sealing covers 3 and the corresponding aeration holes 2 form a releasable sealing cooperation, and a filter plate 6 is provided in the aeration hole 2.

[0026] The device is supplied with compressed air through an external air source. During the reaction, the compressed air enters the annular pipe 1 through the vent pipe 7, and the sealing cover 3 is opened by the air pressure. The compressed air is released from the aeration hole 2 to form aeration in the reaction tank, thereby improving the reaction efficiency of the phosphorus-containing water and lime.

[0027] When the reaction stops, the gas supply is gradually stopped, and the blocking cover 3 is reclosed by the rebound hinge mechanism 4 until no gas is released, forming a blockage with the corresponding aeration hole 2. It stops in time, and the filter plate 6 prevents the calcium phosphate generated by the reaction from entering. The calcium phosphate is blocked by the filter plate 6 and temporarily stored in the aeration hole 2 after blocking. It is flushed out by compressed air during the next aeration to complete the cleaning, and the cleaning is automatic to prevent blockage.

[0028] As a preferred embodiment 2, the sealing cover 3 includes a curved top cover 301, which is fitted with the outer wall of the annular tube 1 at the corresponding aeration hole 2. One side of the curved top cover 301 forms a rebound hinged fit with the annular tube 1 through a rebound hinge mechanism 4. A sealing column 302 is provided at the bottom of the curved top cover 301, which forms a sealing fit with the corresponding aeration hole 2 to ensure the effectiveness of the sealing. The size of the curved top cover 301 is not smaller than the aeration hole 2 and is used to cover the hole opening, while the sealing column 302 is used to seal the hole.

[0029] The arc-shaped top cover 301 is concentric and coaxial with the corresponding aeration hole 2, and the blocking column 302 is concentric and coaxial with the corresponding arc-shaped top cover 301, thereby ensuring the stability of the blocking.

[0030] The bottom of the blocking column 302 does not contact the filter plate 6, so as to avoid conflict between blocking and filtering and prevent them from interfering with each other.

[0031] As a preferred embodiment 3, a sealing ring 5 is coaxially and concentrically embedded in the aeration hole 2 located at the top of the filter plate 6, and the sealing column 302 is embedded in the sealing ring 5 to form a sealing fit, further improving the sealing performance of the sealing.

[0032] As a preferred embodiment 4, the rebound hinge mechanism 4 includes an extension block 401 horizontally arranged on one side of the arc-shaped top cover 301, the extension block 401 is radially parallel to the corresponding aeration hole 2, both ends of the extension block 401 are hingedly matched with the annular tube 1 through the hinge 402, the hinge 402 is symmetrically arranged about the extension block 401, and a torsion spring 403 is provided between the two ends of the extension block 401 and the corresponding hinge 402. The torsion spring 403 is concentrically and coaxially sleeved on the rotating shaft of the hinge 402, one end of the torsion spring 403 is fixed to the extension block 401, and the other end is fixed to the corresponding side hinge 402 to realize the rebound hinge. When the pressure provided by the air pressure is greater than the torsional elastic force, the torsion spring 403 stores energy and the sealing cover 3 opens, and when the pressure provided by the air pressure is less than the torsional elastic force, the torsion spring 403 releases energy and the sealing cover 3 is closed.

[0033] As a preferred embodiment 5, the ventilation pipe 7 is arranged radially along the annular pipe 1, and the ventilation pipe 7 and the annular pipe 1 are integrally formed and connected, which is convenient for arrangement and saves arrangement space.

[0034] The vent pipe 7 is sealed and passes through the reaction pool and is sealed and connected to the external air source. An air intake check valve 9 and a pressure gauge 8 are sequentially provided on the portion of the vent pipe 7 outside the reaction pool along the ventilation direction to ensure air intake safety and prevent backflow.

[0035] As a preferred embodiment 6, the entire device is made of 304DN50 stainless steel, and an aeration hole 2 with a diameter of 1 cm is excavated every 30 cm on the DN50 annular pipe 1. An embedded sealing rubber ring and a sealing cover 3 with a diameter of 1.3 cm are installed at the air outlet with a diameter of 1 cm.

[0036] The working principle of this utility model:

[0037] The utility model provides compressed air through an external air source. During the reaction, the compressed air enters the annular pipe 1 through the vent pipe 7, and the sealing cover 3 is opened by air pressure. The compressed air is released from the aeration hole 2 to form aeration in the reaction tank, thereby improving the reaction efficiency of the phosphorus-containing water and lime.

[0038] When the reaction stops, the gas supply is gradually stopped, and the blocking cover 3 is reclosed by the rebound hinge mechanism 4 until no gas is released, thereby blocking the corresponding aeration hole 2 and stopping in time. The filter plate 6 prevents the calcium phosphate generated by the reaction from entering.
