Description

Technical Field

[0001] The present invention relates to the technical field of phosphorus recovery, and particularly to a phosphorus recovery device for phosphorus-containing water. Background Art

[0002] Phosphorus is largely input and used as raw materials for fertilizers, industrial drugs, etc., food, and feed. However, eutrophication of water areas caused by feces, miscellaneous wastewater, industrial wastewater from factories, livestock waste, discharges from cultivated land, etc. has become a problem.

[0003] Known existing phosphorus removal methods are biological phosphorus removal methods, simultaneous coagulation methods, and crystallization dephosphorization methods. The principle of the biological phosphorus removal method is as follows. That is, by not performing aeration in a part of the aeration tank and setting it to an anaerobic state, the amount of phosphorus extracted as excess sludge can be more than that of the usual treatment method. In the prior art, when performing decarbonation treatment on phosphorus-containing water, calcium ions (calcium chloride) are supplied to the phosphorus-containing water or the reaction tank, a dephosphorization material mainly composed of calcium silicate hydrate is filled, or the phosphorus-containing water containing phosphorus is circulated in a reaction tank through which it flows for dephosphorization. When using an existing stirrer to mix the phosphorus-containing water and calcium chloride, there is a problem of low mixing efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose a phosphorus recovery device for phosphorus-containing water.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

A delivery pump is installed on the side of the housing for pumping out the mixed materials in the housing. An upper feeding mechanism for feeding calcium chloride is arranged inside the housing. The upper feeding mechanism includes an upper feeding housing installed on the inner wall of the bottom of the housing. A winding shaft is movably installed at the top inside the upper feeding housing. A connecting rope is wound around the side of the winding shaft. One end of the connecting rope away from the winding shaft is installed with a movable plug. A magnetic component is installed at the bottom of the movable plug. An extension pipe is arranged at the top of the side of the upper feeding housing. It also includes a second driving component for driving the winding shaft to rotate. A lifting sleeve is sleeved on the circumferential outer wall of the upper feeding housing. The position of the lifting sleeve corresponds to the position of the magnetic component. A pressure sensor is installed on the side of the lifting sleeve. A stirring mechanism for stirring the phosphorus-containing water and calcium chloride fed into the housing is arranged inside the housing. The stirring mechanism includes a rotating seat movably installed on the inner wall of the top of the housing. A vertically arranged extension rod is installed at the bottom of the rotating seat. Stirring components are arranged on the side of the extension rod. It also includes a first driving component for driving the rotating seat to rotate. An installation rod is installed on one side of the extension rod close to the upper feeding housing. A sealing mechanism is arranged at one end of the installation rod close to the upper feeding housing. It also includes a feeding pump for feeding calcium chloride into the upper feeding housing after the mixed materials in the upper feeding housing are pumped out by the delivery pump.

[0007] Preferably, a clamping groove is formed on the circumferential inner wall of the lifting sleeve, and a rolling part is clamped inside the clamping groove.

[0008] Preferably, the sealing mechanism includes a groove formed on one side. A sealing component is installed inside the groove through a telescopic component. The outer diameter of the sealing component is adapted to the inner diameter of the extension pipe.

[0009] Preferably, one side of the sealing component close to the extension pipe is of an arc surface structure.

[0010] Preferably, a positioning mechanism is arranged at one end of the installation rod close to the extension pipe for positioning the position of the installation rod when the openings of the groove and the extension pipe need to be aligned.

[0011] Preferably, the positioning mechanism includes positioning wings installed on the outer wall of the installation rod. An electromagnetic movable sleeve is sleeved on the outer wall of the extension pipe. One side of the electromagnetic movable sleeve away from the positioning wings is connected to the outer wall of the upper feeding housing through a spring.

[0012] Preferably, a through hole is formed on the side of the positioning wing.

[0014] The beneficial effects of the present invention are as follows:

[0015] During use, phosphorus-containing water is fed into the shell through the feeding pipe. As the phosphorus-containing water is fed into the shell, when the pressure sensor detects the pressure of the liquid, the second driving component drives the winding shaft to rotate and wind the connecting rope, driving the movable plug to move upward in the feeding shell, pushing the calcium chloride in the feeding shell to the extension pipe for feeding. And as the movable plug moves upward, the lifting sleeve rises with the rise of the movable plug under the magnetic attraction of the magnetic component until the pressure sensor no longer detects the pressure of the liquid, and the winding shaft stops winding the connecting rope. This process is repeated to achieve feeding the corresponding amount of calcium chloride with the feeding of the phosphorus-containing water, which is convenient and efficient. The rotating seat can be driven by the first driving component to rotate, driving the stirring component and the extension rod to stir and mix the materials in the shell. After the mixing is completed, the materials in the shell are pumped out through the delivery pump. After the materials in the shell are pumped out, the first driving component drives the rotating seat to rotate to align the end of the mounting rod with the opening of the extension pipe, and the sealing mechanism plugs and seals the inside of the extension pipe. Then, calcium chloride is fed into the feeding shell through the feeding pump. Driven by the fed calcium chloride, the movable plug moves down to the bottom of the feeding shell, and at the same time, the lifting sleeve moves down and resets to the bottom of the feeding shell with the magnetic component and the movable plug, which is convenient and efficient to use.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In one embodiment, referring to Figures 1 to 4 , a phosphorus recovery device for phosphorus-containing water includes a housing 1. A feeding pipe 6 is arranged at the top of the housing 1 for feeding phosphorus-containing water; a transfer pump 2 is installed on the side of the housing 1 for pumping out the mixed materials in the housing 1. A feeding mechanism 8 is arranged inside the housing 1 for feeding calcium chloride; the feeding mechanism 8 includes a feeding housing 81 installed on the inner wall of the bottom of the housing 1. A winding shaft 85 is movably installed at the top inside the feeding housing 81. A connecting rope 83 is wound around the side of the winding shaft 85. One end of the connecting rope 83 away from the winding shaft 85 is installed with a movable plug 82, and a magnetic component 7 is installed at the bottom of the movable plug 82; an extension pipe 86 is arranged at the top of the side of the feeding housing 81; it also includes a second driving component 84 for driving the winding shaft 85 to rotate; a lifting sleeve 9 is sleeved on the circumferential outer wall of the feeding housing 81. The position of the lifting sleeve 9 corresponds to the position of the magnetic component 7, and a pressure sensor 5 is installed on the side of the lifting sleeve 9; an agitation mechanism 3 is arranged inside the housing 1 for agitating the phosphorus-containing water and calcium chloride fed into the housing 1; the agitation mechanism 3 includes a rotating seat 33 movably installed on the inner wall of the top of the housing 1. A vertically arranged extension rod 34 is installed at the bottom of the rotating seat 33, and an agitation component 31 is arranged on the side of the extension rod 34; it also includes a first driving component 32 for driving the rotating seat 33 to rotate; a mounting rod 12 is installed on the side of the extension rod 34 close to the feeding housing 81, and a sealing mechanism 10 is arranged at one end of the mounting rod 12 close to the feeding housing 81; it also includes a feeding pump 4 for feeding calcium chloride into the feeding housing 81 after the mixed materials in the feeding housing 81 are pumped out by the transfer pump 2.

[0023] During use, phosphorus-containing water is fed into the housing 1 through the feeding pipe 6. As the phosphorus-containing water is fed into the housing 1, when the pressure sensor 5 detects the pressure of the liquid, the second driving member 84 drives the winding shaft 85 to rotate and wind up the connecting rope 83, driving the movable plug 82 to move upward in the feeding housing 81, pushing the calcium chloride in the feeding housing 81 to the extension pipe 86 for feeding. And as the movable plug 82 moves upward, the lifting sleeve 9 rises with the movable plug 82 under the magnetic attraction of the magnetic member 7 until the pressure sensor 5 no longer detects the pressure of the liquid, at which time the winding shaft 85 stops winding up the connecting rope 83. This process is repeated to achieve feeding of the corresponding amount of calcium chloride along with the feeding of the phosphorus-containing water, which is convenient and efficient. The rotating seat 33 can be driven to rotate by the first driving member 32, driving the stirring member 31 and the extension rod 34 to stir and mix the materials in the housing 1. After the mixing is completed, the materials in the housing 1 are pumped out by the delivery pump 2. After the materials in the housing 1 are pumped out, the first driving member 32 drives the rotating seat 33 to rotate to align the end of the mounting rod 12 with the opening of the extension pipe 86, and the sealing mechanism 10 plugs and seals the inside of the extension pipe 86. Then, calcium chloride is fed into the feeding housing 81 by the feeding pump 4. Driven by the fed calcium chloride, the movable plug 82 moves downward to the bottom of the feeding housing 81, and at the same time, the lifting sleeve 9 moves downward and resets to the bottom of the feeding housing 81 with the magnetic member 7 and the movable plug 82, which is convenient and efficient to use.

[0024] As a preferred embodiment of the present invention, the movable plug 82 is made of materials such as rubber and silica gel. In this embodiment, the preferred movable plug 82 is made of rubber.

[0025] As a preferred embodiment of the present invention, a clamping groove is provided on the inner circumferential wall of the lifting sleeve 9, and a rolling member is clamped inside the clamping groove, which is used to reduce the friction between the inner wall of the lifting sleeve 9 and the outer wall of the feeding housing 81 when the lifting sleeve 9 moves up and down along the outer wall of the feeding housing 81 with the magnetic member 7.

[0026] As a preferred embodiment of the present invention, the rolling member is a ball, a movable roller, etc. In this embodiment, the preferred rolling member is a ball.

[0027] As a preferred embodiment of the present invention, the sealing mechanism 10 includes a groove 103 opened on one side, and a sealing member 102 is installed inside the groove 103 through a telescopic member 101, and the outer diameter of the sealing member 102 is adapted to the inner diameter of the extension pipe 86.

[0028] As a preferred embodiment of the present invention, one side of the sealing member 102 close to the extension pipe 86 is an arc surface structure. When the end position of the mounting rod 12 is aligned with the opening position of the extension pipe 86, the sealing member 102 can be pushed by the telescopic member 101 to the opening at one end of the extension pipe 86 close to the feeding housing 81 to seal the interior of the feeding housing 81. This ensures that when calcium chloride is fed into the feeding housing 81 by the feeding pump 4, the calcium chloride will not overflow from the opening of the extension pipe 86, and it also avoids the situation where part of the calcium chloride remains inside the extension pipe 86.

[0029] As a preferred embodiment of the present invention, the telescopic member 101 is an electric telescopic rod, a hydraulic cylinder, etc. In this embodiment, the preferred telescopic member 101 is an electric telescopic rod.

[0030] As a preferred embodiment of the present invention, a positioning mechanism 13 is provided at one end of the mounting rod 12 close to the extension pipe 86, which is used to position the mounting rod 12 when the opening of the groove 103 needs to be aligned with the opening position of the extension pipe 86.

[0031] As a preferred embodiment of the present invention, the positioning mechanism 13 includes positioning flanks 133 mounted on the outer wall of the mounting rod 12; an electromagnetic movable sleeve 131 is sleeved on the outer wall of the extension pipe 86, and one side of the electromagnetic movable sleeve 131 away from the positioning flanks 133 is connected to the outer wall of the feeding housing 81 through a spring.

[0032] As a preferred embodiment of the present invention, a through hole 132 is formed on the side surface of the positioning flank 133, and a positioning insertion rod 134 is provided on one side of the electromagnetic movable sleeve 131 close to the positioning flank 133. The outer diameter of the positioning insertion rod 134 is adapted to the inner diameter of the opening of the through hole 132. When the end of the mounting rod 12 moves to the opening of the extension pipe 86, the electromagnetic movable sleeve 131 is energized and magnetically attracted to the side surface of the positioning flank 133. At this time, the positioning insertion rod 134 is inserted into the through hole 132 to position the mounting rod 12. When the opening of the extension pipe 86 does not need to be sealed, the spring pushes the electromagnetic movable sleeve 131 to move horizontally along the outer wall of the extension pipe 86 and reset, and at this time, the positioning insertion rod 134 moves out of the opening of the through hole 132.

[0033] As a preferred embodiment of the present invention, a sliding groove is formed on the outer wall of the extension pipe 86, and a sliding block is provided on the inner circumferential wall of the electromagnetic movable sleeve 131. The outer diameter of the sliding block is adapted to the inner diameter of the sliding groove, which is used to guide the horizontal movement of the electromagnetic movable sleeve 131.

[0034] During use, phosphorus-containing water is fed into the housing 1 through the feeding pipe 6. As the phosphorus-containing water is fed into the housing 1, when the pressure sensor 5 detects the pressure of the liquid, the second driving component 84 drives the winding shaft 85 to rotate and wind up the connecting rope 83, driving the movable plug 82 to move upward in the feeding housing 81, pushing the calcium chloride in the feeding housing 81 to the extension pipe 86 for feeding. And as the movable plug 82 moves upward, the lifting sleeve 9 rises with the rise of the movable plug 82 under the magnetic attraction of the magnetic component 7 until the pressure sensor 5 no longer detects the pressure of the liquid, then the winding shaft 85 stops winding up the connecting rope 83. This process is repeated to achieve feeding the corresponding amount of calcium chloride along with the feeding of the phosphorus-containing water, which is convenient and efficient. The rotating seat 33 can be driven by the first driving component 32 to rotate, driving the stirring component 31 and the extension rod 34 to stir and mix the materials in the housing 1. After the mixing is completed, the materials in the housing 1 are pumped out by the delivery pump 2. After the materials in the housing 1 are pumped out, the first driving component 32 drives the rotating seat 33 to rotate to align the end position of the mounting rod 12 with the opening position of the extension pipe 86, and the sealing mechanism 10 plugs and seals the inside of the extension pipe 86. Then, calcium chloride is fed into the feeding housing 81 by the feeding pump 4. Driven by the fed calcium chloride, the movable plug 82 moves downward to the bottom of the feeding housing 81, and at the same time, the lifting sleeve 9 moves downward and resets to the bottom of the feeding housing 81 with the magnetic component 7 and the movable plug 82, which is convenient and efficient to use; when the end position of the mounting rod 12 is aligned with the opening position of the extension pipe 86, the sealing component 102 can be pushed by the telescopic component 101 to the opening at one end of the extension pipe 86 close to the feeding housing 81 to seal the inside of the feeding housing 81, ensuring that when calcium chloride is fed into the feeding housing 81 by the feeding pump 4, the calcium chloride will not overflow from the opening of the extension pipe 86 and also avoiding the situation that part of the calcium chloride remains inside the extension pipe 86; when the end of the mounting rod 12 moves to the opening of the extension pipe 86, the electromagnetic movable sleeve 131 is electrified and magnetically attracted to the side of the positioning flank 133, and at this time, the positioning plug 134 is inserted into the through hole 132 to position the position of the mounting rod 12. When the opening of the extension pipe 86 does not need to be sealed, the spring pushes the electromagnetic movable sleeve 131 to move horizontally along the outer wall of the extension pipe 86 and reset, and at this time, the positioning plug 134 moves out of the opening of the through hole 132.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
