Description

Technical Field

[0001] The invention relates to the technical field of anaerobic treatment, in particular to anaerobic reaction equipment for sludge treatment. Background Art

[0002] Anaerobic refers to an organism or cell that can grow in the absence or lack of molecular oxygen; a microorganism that does not require free oxygen to grow, such as Desulfovibrio, Shigella, Clostridium butyricum, etc.

[0003] Anaerobic reaction equipment generally requires stirring, because the fermentation process not only requires these microorganisms to produce metabolites (products), but also requires them to reproduce. Microorganisms have contact inhibition of reproduction, that is, if the microorganisms are too close after binary fission, it will affect the next binary fission. Stirring can make the cells evenly dispersed, so anaerobic fermentation requires stirring;

[0004] The existing technology usually uses stirring blades for stirring, and in order to avoid generating loud noise or suppress splashing, the rotation speed of the stirring blades is usually not fast. Although the stirring effect can be achieved, due to the lack of the impact effect of the stirring blades, some sludge lumps may not be easily crushed into fine powder, affecting the secondary division of microorganisms and affecting the anaerobic reaction. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an anaerobic reaction device for sludge treatment to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0041] Example:

[0042] like Figure 1-4As shown, this embodiment discloses an anaerobic reaction device for sludge treatment, including an anaerobic tank 100 and a filter press 200. The anaerobic tank 100 has:

[0043] The lifting plate 500 divides the interior of the anaerobic tank 100 into an upper cavity 110 and a lower cavity 120. The space above the lifting plate 500 is the upper cavity 110, and the space below the lifting plate 500 is the lower cavity 120.

[0044] The telescopic member 510 drives the lifting plate 500 to move up and down. The telescopic member 510 can be an electric telescopic rod, a hydraulic telescopic rod or a pneumatic rod;

[0045] The communication port 520 is used for allowing the liquid in the anaerobic tank 100 to flow back and forth between the upper cavity 110 and the lower cavity 120 through the communication port 520 when the telescopic member 510 drives the lifting plate 500 to move upward or downward.

[0046] The lifting plate 500 is moved up and down by the telescopic member 510. During this movement, the liquid inside the anaerobic tank 100 can flow from the upper cavity 110 or the lower cavity 120 to the lower cavity 120 or the upper cavity 110, thereby causing the sludge mixture in the upper and lower parts to react up and down, achieving the same effect as stirring.

[0047] As an optimized embodiment, the communication port 520 may also be arranged at an angle, so that when the liquid flows through the communication port 520 into the upper cavity 110 or the lower cavity 120 , the liquid may hit the inner wall of the anaerobic tank 100 ;

[0048] like Figure 2-5 As shown, the above solution can have two modes:

[0049] The first way: from the perspective of the front cross-sectional view, the communicating ports 520 on both sides are in a positive "V" shape. In this case, when the lifting plate 500 is driven by the telescopic member 510 to move downward, the liquid inside the lower cavity 120 is squeezed, so the excess liquid will be squeezed out from the communicating port 520 into the upper cavity 110. Since the communicating port 520 has an inclined shape, the extrusion trajectory of the liquid is also inclined. Therefore, after being squeezed out, the inclined liquid will hit the inner wall of the anaerobic tank 100, so that the mud blocks in the liquid can be broken up and become fine powder. Then the telescopic member 510 drives the lifting plate 500 to move upward. At this time, the liquid inside the upper cavity 110 is squeezed, and the liquid moves from the communicating port 520 into the lower cavity 120. When the liquid moves into the lower cavity 120, the liquid water column of this part will impact the liquid below, so that the sludge below can be washed away, further improving the speed of mud block dispersion.

[0050] The second way: from the perspective of the front cross-sectional view, the connecting ports 520 on both sides are in an inverted "V" shape (not shown in the figure). In this case, when the lifting plate 500 moves upward under the drive of the telescopic member 510, the liquid inside the upper cavity 110 is squeezed, so the excess liquid will be squeezed out from the connecting port 520 into the lower cavity 120. Since the connecting port 520 has an inclined shape, the extrusion trajectory of the liquid is also inclined. Therefore, after being squeezed out, the inclined liquid will hit the inner wall of the anaerobic tank 100, so that the mud blocks in the liquid can be broken up and become fine powder. Then the telescopic member 510 drives the lifting plate 500 to move downward. At this time, the liquid inside the lower cavity 120 is squeezed, and the liquid moves from the connecting port 520 to the upper cavity 110. When the liquid moves into the upper cavity 110, this part of the liquid water column will impact the liquid above (such as Figure 2 As shown by the straight line oblique arrow in the figure), the sludge that has not been completely dispersed above can be further dispersed, further improving the speed and completion of mud block dispersion;

[0051] It should be noted that the above two methods have one thing in common: since the diameter of the communication port 520 can be set to any size, there is a certain probability that water with mud blocks will be broken up when it enters the communication port 520.

[0052] There are two situations for setting the lifting plate 500:

[0053] The first case: the outer wall of the lifting plate 500 can contact the inner wall of the anaerobic tank 100;

[0054] In the above solution, the outer wall of the lifting plate 500 is in contact with the inner wall of the anaerobic tank 100 (which can be understood as a nearly sealed state, where liquid is essentially unable to flow through the gap between the lifting plate 500 and the anaerobic tank 100. Of course, it can also be a completely sealed state, where liquid is completely unable to flow through the gap between the lifting plate 500 and the anaerobic tank 100). In this solution, liquid can basically only flow through the communication port 520, thereby increasing the water pressure of the liquid squeezed out of the communication port 520, thereby increasing the impact force.

[0055] The second situation: there may be a gap between the outer wall of the lifting plate 500 and the inner wall of the anaerobic tank 100;

[0056] like Figure 6 As shown, in the above solution, when the lifting plate 500 moves up and down, the liquid can flow through the gap between the lifting plate 500 and the inner wall of the anaerobic tank 100. This method is different from the method in the first case in that in this solution, convection can be formed when the liquid flows in the gap.

[0057] like Figure 1As shown, as an optimized embodiment, the reaction equipment may further include a pump 300. The anaerobic tank 100 and the filter press 200 are connected by a pipe 400. The pump 300 pumps the sludge water into the anaerobic tank 100. The water flowing out of the anaerobic tank 100 is filtered by the filter press 200. The water in the anaerobic tank 100 is then injected into the anaerobic tank 100 through a return pipe 410.

[0058] In the above solution, after the anaerobic work is completed or when the proportion of sludge is too large, the sludge water can be filtered through the filter press 200 and then discharged back into the anaerobic tank 100 to adjust the proportion of sludge and water.

[0059] As an optimized embodiment, a flow-turbulating device is installed inside the anaerobic tank 100. The flow-turbulating device includes at least one flow-turbulating block. The flow-turbulating block is fixed to the inner wall of the anaerobic tank 100. The flow-turbulating block moves inside the anaerobic tank 100 under the drive of the driving device.

[0060] It should be noted that the above-mentioned driving device can be a motor.

[0061] As an optimized embodiment, the spoiler device includes:

[0062] The rotating ring 610 rotates under the drive of the driving device, and the spoiler is installed on the rotating ring 610;

[0063] The driving column 700 is connected to the middle portion of the rotating ring 610 , and the driving column 700 is rotatably connected to the middle portion of the lifting plate 500 via a bearing.

[0064] The spoiler also includes:

[0065] The rotating sleeve 650 is connected to the bottom of the lifting plate 500;

[0066] A rotating post 620 rotatably connected to the interior of the rotating sleeve 650 and extending to the top of the lifting plate 500 ; and

[0067] A pinion 621 is connected to the top of the rotating column 620;

[0068] The drive column 700 has teeth throughout its entire circle, which mesh with the pinion 621;

[0069] The pinion rotates under the drive of the rotating drive member;

[0070] It should be noted that the above-mentioned rotating driving member can be a motor.

[0071] A countersunk hole 630 is provided on the inner wall of the rotating sleeve 650, and a spiral groove 640 is provided on the inner wall of the countersunk hole 630. A plug post 670 is provided inside the countersunk hole 630, and a protrusion 690 is connected to the outer wall of the plug post 670. When the plug post 670 moves up and down, the protrusion 690 slides inside the spiral groove 640.

[0072] The outer wall of the plug post 670 is further connected to a movable sleeve 660, which is sleeved on the outer wall of the rotating sleeve 650. A spring 680 is connected between the inner wall of the movable sleeve 660 and the rotating sleeve 650.

[0073] According to the above solution, when the lifting plate 500 moves linearly and the side on which the movable sleeve 660 is installed approaches the inner wall of the anaerobic tank 100, the movable sleeve 660 and the anaerobic tank 100 are abutted, thereby causing the spring 680 to contract and the plug post 670 to move toward one side of the rotating ring 610. As the plug post 670 moves up and down, the protrusion 690 slides inside the spiral groove 640, thereby causing the rotating post 620 with the spiral groove 640 to rotate. The rotation of the rotating post 620 causes the pinion 621 to rotate synchronously. Since the pinion 621 meshes with the teeth on the rotating ring 610, the rotating ring 610 is also driven to rotate, thereby rotating the spoiler on the rotating ring 610.

[0074] The rotation of the spoiler has two effects:

[0075] 1. It can disturb the liquid and achieve a stirring effect;

[0076] Second, the liquid squeezed out of the communication port 520 can be impacted by the flow-disrupting block, so the sludge can be dispersed, further increasing the speed of dispersing the sludge.

[0077] Although the 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 invention, and that the scope of the invention is defined by the appended claims and their equivalents.
