Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated rapid separation and denitrification device. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a water body or reuse. In the wastewater treatment process, an integrated rapid separation and nitrogen removal device is required to remove nitrogen from the wastewater.

[0003] Publication No. "CN217921619U" provides an MBBR integrated autotrophic denitrification device, comprising a denitrification box body; a jacking structure, which is fixedly arranged on the lower wall of the denitrification box body and located at the center; an oxygen supply structure, which is fixedly arranged in the denitrification box body and located above the jacking structure; the jacking structure comprises a bearing frame, a limit rod, a spiral rod, a protective box, a motor, a sliding frame and a jacking roller; the utility model relates to the technical field of denitrification equipment, and the MBBR integrated autotrophic denitrification device can realize the wave-like lifting and swinging of the jacking belt by moving the jacking structure left and right, thereby promoting the internal active sludge to drive the medium to fully mix with oxygen in a flowing state, promoting the denitrification reaction, improving the internal denitrification effect, and avoiding incomplete denitrification due to the flow of active sludge;

[0004] However, the above device still has the following problems during implementation:

[0005] Sulfur autotrophic deep denitrification technology is a wastewater denitrification technology based on the principle of sulfur autotrophic denitrification. This technology uses sulfide as an electron donor to convert nitrate nitrogen in wastewater into nitrogen gas, thereby achieving the purpose of denitrification. When in use, a certain amount of sulfur-loaded denitrification balls are put into the integrated rapid separation denitrification device. When the sewage enters the integrated rapid separation denitrification device, the denitrification effect can be achieved. However, the sulfur-loaded denitrification balls themselves have gravity, and they are easily deposited and accumulated in the integrated rapid separation denitrification device, so that they cannot fully contact with the sewage, thereby affecting the denitrification effect. Utility Model Content

[0006] The purpose of the utility model is to provide an integrated rapid separation and denitrification device to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An integrated rapid separation denitrification device comprises a denitrification box body, wherein a toggle mechanism is arranged inside the denitrification box body, and the accumulation of sulfur-carrying denitrification balls can be avoided by toggle;

[0009] The toggling mechanism includes a motor fixedly arranged on one side of the denitrification tank body. The output end of the motor penetrates through the inner wall of the denitrification tank body and is fixedly connected with a reciprocating lead screw. A moving block is drivingly connected to the surface of the reciprocating lead screw. A plurality of toggling rods are fixedly connected to the top and bottom of the moving block;

[0010] A gas collection mechanism is fixedly arranged on one side of the denitrification tank body. When the toggling mechanism operates, the gas collection mechanism will collect gas and spray it into the interior of the denitrification tank body.

[0011] By setting the toggling mechanism, the motor can be started to drive the reciprocating lead screw to rotate. When the reciprocating lead screw rotates, it will drive the moving block. Under the restriction of the guide rail and the guide groove, the moving block will move reciprocally, and the moving block will drive the toggling rods to move reciprocally, thereby dispersing the accumulated sulfur-carrying denitrification balls, making the sulfur-carrying denitrification balls evenly contact with the sewage, and thus improving the denitrification effect.

[0012] Preferably, the gas collection mechanism includes two gas collection boxes fixedly arranged on one side of the denitrification tank body. An air inlet pipe is fixedly communicated with the top of the gas collection box. A pushing block is arranged inside the gas collection box. One side of the pushing block is fixedly connected with a pushing rod. One end of the pushing rod penetrates through the inner wall of the denitrification tank body and is fixedly connected with a pressing block. The pressing block is opposite to the position of the moving block. A tension spring is sleeved on the surface of the pushing rod. One end of the tension spring is fixedly connected with one side of the pushing block, and the other end of the tension spring is fixedly connected with the inner wall of the gas collection box.

[0013] Preferably, the gas collection mechanism further includes a transmission pipe fixedly communicated with one side of the gas collection box. One end of the transmission pipe is fixedly connected with a compression box. One side of the compression box is fixedly connected with one side of the denitrification tank body. A plurality of air injection pipes are fixedly communicated with one side of the compression box through a one-way pressure valve. One end of the air injection pipe penetrates through the inner wall of the denitrification tank body.

[0014] By setting the gas collection mechanism, when the moving block contacts the pressing block during the moving process, it will push the pressing block to move. The pressing block will drive the pushing rod, the pushing block and the piston to move inside the gas collection box, compress the gas in the gas collection box and pass it through the transmission pipe into the compression box. When the moving block moves to a position where it does not contact the pressing block, the pulling force generated by the tension spring will drive the pushing block and the piston to reset. At this time, the gas collection box is in a negative pressure state, and the gas will enter the gas collection box through the air inlet pipe. In this way, the gas is intermittently transported to the compression box in a cycle. When the gas inside the compression box reaches the limit of the one-way pressure valve, the gas is intermittently ejected from the air injection pipe to disperse the sulfur-carrying denitrification balls accumulated on both sides of the denitrification tank body, thereby improving the denitrification effect.

[0015] Preferably, a first one-way valve is fixedly installed on the surface of the air inlet pipe, and a second one-way valve is fixedly installed on the surface of the transmission pipe.

[0016] By setting a first one-way valve and a second one-way valve, the first one-way valve is a valve that can only let air into the air collecting box, and the second one-way valve is a valve that can only let air into the compression box. This can ensure that during the reciprocating movement of the piston, gas will enter the air collecting box through the air intake pipe. At the same time, when the gas in the air collecting box is compressed, the gas can only enter the compression box through the transmission pipe.

[0017] Preferably, one side of the pushing block is fixedly connected with a piston, and the piston is made of rubber.

[0018] By providing a piston, the sealing performance when the push block contacts the gas collecting box can be improved, so that the gas in the gas collecting box can be compressed when the push block moves.

[0019] Preferably, a bearing seat is provided at one end of the reciprocating screw rod, and the reciprocating screw rod is rotatably connected to the inner wall of the denitrification box body through the bearing seat.

[0020] Preferably, guide rails are fixedly connected to both sides of the denitrification box body, and guide grooves for use with the guide rails are provided on both sides of the moving block.

[0021] By setting up the bearing seat, the reciprocating screw can be supported and its stability during rotation can be improved. At the same time, the design of the bearing seat can also make the reciprocating screw rotate more smoothly.

[0022] By providing the guide rail and the guide groove, when the reciprocating screw rod transmits the movement block, the movement block can be restricted to move back and forth only along the track of the guide rail and the guide groove.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] 1. The utility model is provided with a toggle mechanism, which can drive the reciprocating screw to rotate by starting the motor. When the reciprocating screw rotates, it will transmit the moving block, so that the moving block drives the guide rail and the guide groove to move back and forth. The moving block will drive the toggle rod to move back and forth, thereby dispersing the accumulated sulfur-loaded denitrification balls, making the sulfur-loaded denitrification balls evenly contact with the sewage, thereby improving the denitrification effect.

[0025] 2. The utility model is provided with an air collecting mechanism, which can push the pressing block to move when the moving block contacts the pressing block during movement, and the pressing block will drive the pushing rod, the pushing block and the piston to move inside the air collecting box, compressing the gas in the air collecting box through the transmission pipe and entering the compression box. When the moving block moves to a point where it is no longer in contact with the pressing block, the tension generated by the tension spring will drive the pushing block and the piston to reset. At this time, there is a negative pressure in the air collecting box, and the gas will enter the air collecting box through the air intake pipe, thereby cyclically intermittently supplying gas to the compression box. When the gas inside the compression box reaches the limit of the one-way pressure valve, the gas is intermittently ejected from the jet pipe to disperse the sulfur-carrying denitrification balls accumulated on both sides of the denitrification box body, thereby improving the denitrification effect.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 1-5 , the utility model provides a technical solution:

[0034] Embodiment 1:

[0035] An integrated rapid separation denitrification device comprises a denitrification box body 1, wherein a toggle mechanism is arranged inside the denitrification box body 1, and the accumulation of sulfur-carrying denitrification balls can be avoided by toggle;

[0036] One implementation of the first embodiment of the present invention is as follows: the toggle mechanism includes a motor 2 fixedly arranged on one side of the denitrification box body 1, the output end of the motor 2 penetrates the inner wall of the denitrification box body 1, and is fixedly connected to a reciprocating screw 3, the surface of the reciprocating screw 3 is transmission-connected to a moving block 4, and the top and bottom of the moving block 4 are fixedly connected to a plurality of toggle rods 5;

[0037] The gas collecting mechanism is fixedly arranged on one side of the denitrification box body 1 . When the toggle mechanism is in operation, the gas collecting mechanism will collect gas and spray it into the interior of the denitrification box body 1 .

[0038] In this embodiment, considering that the sulfur-carrying denitrification balls themselves have gravity, they are easily accumulated on the bottom when placed in the integrated rapid separation denitrification device, so that they cannot fully contact with the sewage, thereby affecting the denitrification effect. Therefore, by setting a toggle mechanism, the reciprocating screw 3 can be driven to rotate by starting the motor 2. When the reciprocating screw 3 rotates, it will drive the moving block 4, so that the moving block 4 drives the guide rail 19 and the guide groove 20 to move back and forth. The moving block 4 will drive the toggle rod 5 to move back and forth, thereby dispersing the accumulated sulfur-carrying denitrification balls, so that the sulfur-carrying denitrification balls are evenly in contact with the sewage, thereby improving the denitrification effect;

[0039] The problem that the sulfur-carrying denitrification balls have gravity and are easily deposited on the bottom of the integrated rapid denitrification device, which prevents them from fully contacting with the sewage and thus affects the denitrification effect, is solved;

[0040] It should be noted that the distance between the two toggle rods 5 needs to be larger than the diameter of the sulfur-carrying denitrification balls.

[0041] Preferably, a bearing seat 18 is provided at one end of the reciprocating screw rod 3 , and the reciprocating screw rod 3 is rotatably connected to the inner wall of the denitrification box body 1 through the bearing seat 18 .

[0042] In this embodiment, the bearing seat 18 is provided to support the reciprocating screw rod 3 and improve its stability during rotation. At the same time, the design of the bearing seat 18 can also make the reciprocating screw rod 3 rotate more smoothly.

[0043] Preferably, guide rails 19 are fixedly connected to both sides of the denitrification box body 1 , and guide grooves 20 for use with the guide rails 19 are provided on both sides of the moving block 4 .

[0044] In this embodiment, by providing the guide rail 19 and the guide groove 20 , when the reciprocating screw rod 3 transmits the movement block 4 , the movement block 4 can be restricted to reciprocate only along the tracks of the guide rail 19 and the guide groove 20 .

[0045] Embodiment 2:

[0046] On the basis of Example 1, the toggle mechanism in this embodiment can avoid the accumulation of sulfur-loaded denitrification balls by reciprocating the toggle rod 5, thereby improving the denitrification effect of sewage. However, considering that during the toggle mechanism tosses the sulfur-loaded denitrification balls, some of the sulfur-loaded denitrification balls will disperse to both sides and form an accumulation form again, affecting the denitrification effect, in this application, the gas collecting mechanism includes two gas collecting boxes 6 fixedly arranged on one side of the denitrification box body 1, the top of the gas collecting box 6 is fixedly connected to the air intake pipe 7, a push block 8 is arranged inside the gas collecting box 6, one side of the push block 8 is fixedly connected to a push rod 9, one end of the push rod 9 passes through the interior of the denitrification box body 1, and is fixedly connected to a pressing block 10, the pressing block 10 is opposite to the moving block 4, and the surface of the push rod 9 is sleeved with a tension spring 11, one end of the tension spring 11 is fixedly connected to one side of the push block 8, and the other end of the tension spring 11 is fixedly connected to the inner wall of the gas collecting box 6.

[0047] The gas collecting mechanism also includes a transmission pipe 12 fixedly connected to one side of the gas collecting box 6, one end of the transmission pipe 12 is fixedly connected to a compression box 13, one side of the compression box 13 is fixedly connected to one side of the denitrification box body 1, one side of the compression box 13 is fixedly connected to a plurality of injection pipes 14 through a one-way pressure valve, and one end of the injection pipe 14 passes through the interior of the denitrification box body 1.

[0048] In this embodiment, it is considered that during the process of the toggle mechanism to toggle the sulfur-carrying denitrification balls, some of the sulfur-carrying denitrification balls will disperse to both sides and form a pile again, which will affect the denitrification effect. Therefore, by setting a gas collecting mechanism, when the moving block 4 contacts the pressing block 10 during the movement, it will push the pressing block 10 to move, and the pressing block 10 will drive the push rod 9, the push block 8 and the piston 17 to move inside the gas collecting box 6, compressing the gas in the gas collecting box 6 through the transmission pipe 12 and entering the compression box 13. When the moving block 4 moves to no longer contact the pressing block 10, the tension generated by the tension spring 11 will drive the push block 8 and the piston 17 to reset. At this time, there is a negative pressure in the gas collecting box 6, and the gas will enter the gas collecting box 6 through the air intake pipe 7, so as to cyclically and intermittently transport gas to the compression box 13. When the gas inside the compression box 13 reaches the limit of the one-way pressure valve, the gas is intermittently ejected from the jet pipe 14 to disperse the sulfur-carrying denitrification balls accumulated on both sides of the denitrification box body 1, thereby improving the denitrification effect.

[0049] The invention solves the problem that, in the process of the sulfur-carrying denitrification balls being moved by the moving mechanism, some of the sulfur-carrying denitrification balls will be dispersed to both sides and piled up again, thus affecting the denitrification effect.

[0050] Preferably, a first one-way valve 15 is fixedly installed on the surface of the air intake pipe 7 , and a second one-way valve 16 is fixedly installed on the surface of the transmission pipe 12 .

[0051] In this embodiment, a first one-way valve 15 and a second one-way valve 16 are provided. The first one-way valve 15 is a valve that can only let air into the air collecting box 6, and the second one-way valve 16 is a valve that can only let air into the compression box 13. This ensures that during the reciprocating movement of the piston 17, the gas enters the air collecting box 6 through the air intake pipe 7. At the same time, when the gas in the air collecting box 6 is compressed, the gas can only enter the compression box 13 through the transmission pipe 12.

[0052] Preferably, a piston 17 is fixedly connected to one side of the push block 8, and the material of the piston 17 is rubber.

[0053] In this embodiment, by providing the piston 17, the sealing performance when the push block 8 contacts the gas collecting box 6 can be improved, so that the gas in the gas collecting box 6 can be compressed when the push block 8 moves.

[0054] Working principle: The user starts the motor 2 to drive the reciprocating screw 3 to rotate. When the reciprocating screw 3 rotates, it will drive the moving block 4, so that the moving block 4 drives the guide rail 19 and the guide groove 20 to move back and forth. The moving block 4 will drive the toggle rod 5 to move back and forth, thereby dispersing the accumulated sulfur-carrying denitrification balls, so that the sulfur-carrying denitrification balls are evenly in contact with the sewage, thereby improving the denitrification effect;

[0055] When the moving block 4 contacts the pressing block 10 during movement, it will push the pressing block 10 to move, and the pressing block 10 will drive the push rod 9, the push block 8 and the piston 17 to move inside the gas collecting box 6, compressing the gas in the gas collecting box 6 through the transmission pipe 12 and entering the compression box 13. When the moving block 4 moves to a point where it is no longer in contact with the pressing block 10, the tension generated by the tension spring 11 will drive the push block 8 and the piston 17 to reset. At this time, there is a negative pressure in the gas collecting box 6, and the gas will enter the gas collecting box 6 through the air intake pipe 7, thereby intermittently supplying gas to the compression box 13 in a cycle. When the gas inside the compression box 13 reaches the limit of the one-way pressure valve, the gas is intermittently ejected from the jet pipe 14 to disperse the sulfur-carrying denitrification balls accumulated on both sides of the denitrification box body 1, thereby improving the denitrification effect.

[0056] It should be noted that the motor 2 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the motor 2 are clear to those skilled in the art, so they are not described in detail.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
