Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a MCHS high-concentration wastewater pretreatment reactor. Background Art

[0002] The MCHS high-concentration wastewater pretreatment reactor is equipped with MCHS electrochemically active bacteria, mainly aerobic bacteria. The basic structure of the reactor is that the bottom of the MCHS reactor is covered with an aeration system. After the wastewater is pumped into the reactor, it is fully mixed with the MCHS bacteria and undergoes redox reactions with oxygen as an electron acceptor, achieving efficient degradation of organic matter. It has a good treatment effect on high-concentration wastewater, so it is widely used.

[0003] A slow-release device for a defoaming agent in a MCHS bioreactor for high-concentration chemical wastewater with application number 202321327832.5 comprises a reactor body, a defoaming slow-release component is arranged inside the reactor body, the defoaming slow-release component comprises a float, a float cavity is arranged at the bottom of the float, a counterweight block is arranged in the float cavity, and a telescopic rod is arranged on the outer side of the top of the float. In the utility model, the staff adjusts the height of the filter frame according to actual conditions. The worker can pull out the pin and then press the filter frame upward or downward to extend or contract the telescopic rod. After adjusting the specified height, the staff inserts the pin into the pin hole to fix the telescopic rod, thereby restricting the filter frame. Then the staff adds solid defoaming agent to the filter frame and puts it into the reactor body. The float will float above the wastewater. When the foam accumulates to a certain thickness, it will contact with the defoaming agent, thereby achieving a defoaming effect with high quality and efficiency of defoaming.

[0004] This technical solution removes foam by contacting the foam with the defoaming agent, but in actual use, the operation of adding the defoaming agent is rather cumbersome. If the reactor compartment cover adopts a quick-release flange, it is better, but the threaded structure must be loosened first and then the compartment cover must be opened to add the defoaming agent inside. If it is an ordinary reactor compartment cover, the operation is even more cumbersome, and it is necessary to loosen multiple bolts to remove the compartment cover and then add the defoaming agent inside. Both types of compartment covers require the compartment cover and the threaded structure to be reset later, which is time-consuming and labor-intensive. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a MCHS high-concentration wastewater pretreatment reactor to solve the technical problem of inconvenience in adding defoaming agent.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a MCHS high-concentration wastewater pretreatment reactor, comprising a reactor body and a bin cover, wherein the reactor body is respectively connected with guide bars and brackets, and a float bag is arranged on the top of the bracket, a holding rack is fixed on the top of the float bag, and rollers are connected on both sides of the holding rack, a sleeve is fixed on the top of the holding rack, and a first through hole is opened on the outer surface of the sleeve, a fixed tube is connected to the bottom of the bin cover, and a second through hole is opened on the outer surface of the fixed tube, and a funnel is connected to the top of the bin cover.

[0007] By adopting the above technical solution, when it is necessary to add defoaming agent, a small amount of defoaming agent is poured into the funnel, and then the defoaming agent passes through the fixed tube, the sleeve and the first through hole in sequence and flows into the holding rack. The defoaming agent can be added without opening the compartment cover. When the holding rack moves up and down, the sleeve slides up and down on the outer ring of the fixed rack following the up and down displacement of the holding rack. Even if the sleeve completely covers the fixed tube, due to the setting of the second through hole, the defoaming agent can pass through the fixed tube, the second through hole and the first through hole in sequence and flow into the holding rack, which is convenient for adding defoaming agent to the holding racks at different heights.

[0008] Furthermore, the containing rack is in abutment with the bracket, and the roller is rollingly connected with the guide bar.

[0009] By adopting the above technical solution, when the liquid is discharged or the liquid level is low, the float bag is supported by the bracket to limit the position of the holding rack, thereby preventing the holding rack from descending too much and causing the sleeve to separate from the fixed pipe.

[0010] Furthermore, the diameter of the sleeve is greater than the diameter of the fixed tube, and the sleeve is slidably connected to the fixed tube.

[0011] By adopting the above technical solution, when the containing rack moves up and down, the sleeve slides up and down on the outer ring of the fixed rack following the up and down displacement of the containing rack, so as to facilitate adding defoaming agent to the containing racks at different heights.

[0012] Furthermore, the floating bladder is made of silica gel material.

[0013] By adopting the above technical solution, when high-concentration wastewater enters or is discharged after treatment, the float bag floats on the water surface due to the buoyancy, and the buoyancy of the float bag causes the holding rack to move up with the rise of the liquid level and move down with the drop of the liquid level.

[0014] Furthermore, the funnel is communicated with the fixed tube.

[0015] By adopting the above technical solution, the staff pulls off the sealing cover, and then pours a small amount of defoaming agent into the funnel, and then the defoaming agent passes through the fixed tube, the sleeve and the first through hole in sequence and flows into the holding rack.

[0016] Further, the first through hole corresponds to the second through hole.

[0017] By adopting the above technical solution, even if the sleeve completely covers the fixed tube, due to the provision of the second through hole, the defoaming agent can sequentially pass through the fixed tube, the second through hole and the first through hole and flow into the containing rack.

[0018] Furthermore, four rollers and four guide bars are provided, and the four rollers and four guide bars are distributed in a ring array.

[0019] By adopting the above technical solution, firstly, it is prevented that the first through hole cannot correspond to the second through hole due to the rotation of the float bag and the containing rack, and secondly, it is prevented that the containing rack and the float bag can be tilted or deviated.

[0020] Furthermore, the bin cover is connected to the top of the reactor body, an aerator is installed below the inside of the reactor body, and the top of the aerator is connected to an aeration pipe through a one-way valve, an aeration nozzle is fixed on the top of the aeration pipe, and a water inlet and a water outlet are respectively penetrated through the outer surface of the reactor body.

[0021] By adopting the above technical scheme, when the machine is needed to treat high-concentration wastewater, the staff inputs the high-concentration wastewater into the reactor body through the water inlet. After the aerator is started, the high-concentration wastewater in the reactor body is aerated through the aeration pipe, aeration nozzle and one-way valve. At the same time, MCHS bacteria are arranged inside the reactor body to cooperate with the aeration treatment to decompose organic matter in the high-concentration wastewater, so as to achieve the pretreatment effect. When foam is generated in the reactor body, as the foam increases, the foam will contact with the defoaming agent in the holding rack, and the defoaming agent will reduce the surface tension of the foam to cause the foam to break, so as to achieve the purpose of defoaming. After the treatment is completed, the staff will discharge the pretreated high-concentration wastewater through the water outlet to enter the next step.

[0022] Furthermore, a sealing cover is connected to the top of the funnel.

[0023] By adopting the above technical solution, when it is necessary to add defoaming agent, the staff will pull off the sealing cover. After adding the defoaming agent, the staff will insert the sealing cover into the funnel to prevent foreign impurities from falling into the reactor body through the funnel.

[0024] Furthermore, the sealing cover is made of rubber material, and the sealing cover is detachably connected to the funnel.

[0025] By adopting the above technical solution, the sealing cover made of rubber can fit tightly with the inner wall of the funnel, thereby preventing impurities from falling into the reactor body. At the same time, it is a flexible material and is easy to disassemble and assemble.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model is provided with a holding rack, a sleeve, a fixed pipe, a funnel, a first through hole, and a second through hole. When a defoaming agent needs to be added, a small amount of the defoaming agent is poured into the funnel, and then the defoaming agent sequentially passes through the fixed pipe, the sleeve, and the first through hole and flows into the holding rack. The defoaming agent can be added without opening the compartment cover. When the holding rack moves up and down, the sleeve slides up and down on the outer ring of the fixed rack following the up and down displacement of the holding rack. Even if the sleeve completely covers the fixed pipe, due to the provision of the second through hole, the defoaming agent can sequentially pass through the fixed pipe, the second through hole, and the first through hole and flow into the holding rack, which is convenient for adding the defoaming agent to the holding racks at different heights; the defoaming agent can be added without opening the compartment cover;

[0028] 2. The utility model is provided with rollers, guide bars and brackets. When the liquid is discharged or the liquid level is low, the bracket supports the float bag and limits the holding rack to prevent the holding rack from falling too high and causing the sleeve to separate from the fixed tube. At the same time, the rollers and guide bars are used to guide the holding rack and the float bag. First, it is prevented that the float bag and the holding rack rotate and cause the first through hole to be unable to correspond to the second through hole. Second, it is prevented that the holding rack and the float bag tip over or deviate, thereby increasing the stability of the structural operation. BRIEF DESCRIPTION OF THE DRAWINGS

The buoyancy of the float 9 enables the holding rack 10 to move up with the rise of the liquid level and move down with the fall of the liquid level; the holding rack 10 is fixed on the top of the float 9, and rollers 16 are connected to both sides of the holding rack 10, and the rollers 16 are rollingly connected with the guide bar 17, and four rollers 16 and guide bar 17 are arranged, and the four rollers 16 and guide bar 17 are distributed in a ring array, and the holding rack 10 and the float 9 are guided by the rollers 16 and the guide bar 17; a sleeve 11 is fixed on the top of the holding rack 10, and a first passage is provided on the outer surface of the sleeve 11 Hole 14, a fixed tube 12 is connected to the bottom of the bin cover 2, the diameter of the sleeve 11 is larger than the diameter of the fixed tube 12, the sleeve 11 is slidably connected to the fixed tube 12, and the sleeve 11 slides up and down on the outer ring of the fixed frame following the up and down displacement of the holding rack 10, so as to facilitate the addition of defoaming agent to the holding racks 10 at different heights; a second through hole 15 is provided on the outer surface of the fixed tube 12, and the first through hole 14 corresponds to the second through hole 15. Even if the sleeve 11 completely covers the fixed tube 12, due to the setting of the second through hole 15, the defoaming agent can pass through the fixed tube 12, the second through hole 15 and the first through hole 14 in sequence and flow into the holding rack 10; a funnel 13 is connected to the top of the bin cover 2, and the funnel 13 is connected to the fixed tube 12. The staff pours a small amount of defoaming agent into the funnel 13, and then the defoaming agent passes through the fixed tube 12, the sleeve 11 and the first through hole 14 in sequence and flows into the holding rack 10.

[0038] See also Figure 1 and Figure 2 In the above embodiment, the bin cover 2 is connected to the top of the reactor body 1, an aerator 5 is installed at the lower part of the reactor body 1, the top of the aerator 5 is connected to the aeration pipe 6 through the one-way valve 19, and the top of the aeration pipe 6 is fixed with an aeration nozzle 7. After the aerator 5 is started, the high-concentration wastewater in the reactor body 1 is aerated through the aeration pipe 6, the aeration nozzle 7 and the one-way valve 19; the outer surface of the reactor body 1 is respectively penetrated with a water inlet 3 and a water outlet 4, and the high-concentration wastewater is input into the reactor body 1 through the water inlet 3, and after the treatment is completed, the pre-treated high-concentration wastewater is discharged through the water outlet 4 to enter the next step.

[0039] Embodiment 2:

[0040] On the basis of the above-mentioned embodiment 1, although the defoaming agent can be added without opening the chamber cover 2 by providing the holding rack 10, the sleeve 11, the fixed tube 12, the funnel 13, the first through hole 14 and the second through hole 15; however, external impurities may fall into the reactor body 1 through the funnel 13, or fall into the fixed tube 12 and the sleeve 11 to cause pipeline blockage; now, by providing the sealing cover 8, the funnel 13 can be blocked to prevent impurities from entering.

[0041] See also Figure 1 and Figure 2 In the above embodiment, a sealing cover 8 is connected to the top of the funnel 13. The sealing cover 8 is made of rubber material. The sealing cover 8 is detachably connected to the funnel 13. After adding the defoaming agent, the staff inserts the sealing cover 8 into the funnel 13 to prevent external impurities from falling into the reactor body 1 through the funnel 13.

[0042] The implementation principle of the utility model is as follows: first, when it is necessary to add defoaming agent, the staff will pull off the sealing cover 8, and then the staff will pour a small amount of defoaming agent into the funnel 13 to prevent the defoaming agent from overflowing from the top of the holding rack 10, and then the defoaming agent will flow into the holding rack 10 through the fixed tube 12, the sleeve 11 and the first through hole 14 in sequence, and the defoaming agent can be added without opening the compartment cover 2. After the defoaming agent is added, the staff will insert the sealing cover 8 into the funnel 13 to prevent foreign impurities from falling into the reactor body 1 through the funnel 13;

[0043] When the machine is needed to treat the high-concentration wastewater, the staff inputs the high-concentration wastewater into the reactor body 1 through the water inlet 3. After the aerator 5 is started, the high-concentration wastewater in the reactor body 1 is aerated through the aeration pipe 6, the aeration nozzle 7 and the one-way valve 19. At the same time, the reactor body 1 is provided with MCHS bacteria, which cooperates with the aeration treatment to decompose the organic matter in the high-concentration wastewater, so as to achieve the pretreatment effect. When foam is generated in the reactor body, as the foam increases, the foam will contact the defoamer in the holding rack 10, and the defoamer reduces the surface tension of the foam so that the foam breaks, so as to achieve the purpose of defoaming. After the treatment is completed, the staff discharges the pretreated high-concentration wastewater through the water outlet 4 to enter the next step;

[0044] When high-concentration wastewater enters or is discharged after treatment, the float 9 floats on the water surface due to the buoyancy. The buoyancy of the float 9 causes the holding rack 10 to move up with the rise of the liquid level and move down with the drop of the liquid level. When the holding rack 10 moves up and down, the sleeve 11 slides up and down on the outer ring of the fixed rack following the up and down displacement of the holding rack 10. Even if the sleeve 11 completely covers the fixed pipe 12, due to the setting of the second through hole 15, the defoaming agent can sequentially pass through the fixed pipe 12, the second through hole 15 and the first through hole 14 and flow into the holding rack 10, so that the defoaming agent can be added to the holding racks 10 at different heights.

[0045] When the liquid is discharged or the liquid level is low, the bracket 18 is used to support the float 9 to limit the holding rack 10 to prevent the holding rack 10 from descending too much and causing the sleeve 11 to separate from the fixed tube 12. At the same time, the roller 16 and the guide bar 17 are used to guide the holding rack 10 and the float 9. Firstly, it is prevented that the float 9 and the holding rack 10 rotate so that the first through hole 14 cannot correspond to the second through hole 15, and secondly, it is prevented that the holding rack 10 and the float 9 can be tilted or offset.

[0046] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
