Description

Technical Field

[0001] The utility model relates to the technical field of sludge fermentation tanks, in particular to an anaerobic sludge fermentation tank. Background Art

[0002] Anaerobic sludge fermentation tanks are equipment used to treat organic wastewater or waste. They convert organic matter into biogas and sludge through biodegradation under anaerobic conditions. Anaerobic tanks feature efficient internal circulation and mass transfer, capable of treating high-concentration organic wastewater. They occupy a small footprint, have a high organic load, and are highly impact-resistant. The operating principle of anaerobic sludge fermentation tanks is based on the anaerobic fermentation process, utilizing an anaerobic or slightly anoxic environment to promote microbial degradation. The equipment uses internal circulation to disperse and break up bubbles, increasing the dissolved oxygen rate and mixing effect, thereby achieving an efficient fermentation process. Anaerobic tanks typically consist of a cylinder, agitator, feed pipe, and discharge pipe. The internal circulation system promotes uniform mixing and fermentation of materials.

[0003] In the existing sludge fermentation anaerobic tank, uneven material addition will lead to uneven distribution of materials in the tank, with material concentrations in some areas being too high and in some areas being too low, thereby affecting the uniformity and efficiency of the entire fermentation process. This may lead to poor fermentation results, incomplete degradation of organic matter, and affect the quality and yield of the final product.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model provides a technical solution: a sludge fermentation anaerobic tank, comprising a fermentation tank 1, a card cover 2 is provided at the upper end of the fermentation tank 1, and a rotating motor 3 is provided at the upper middle end of the card cover 2, a rotating blade 4 is connected to the lower end of the rotating motor 3, and a feeding assembly 5 is provided at the upper end of the card cover 2;

[0031] The feeding assembly 5 includes a feeding frame 501, a closing cover 502 and a drug discharge nozzle 503. The feeding frame 501 is provided at the upper end of the card cover 2, and the closing cover 502 is installed on the outer surface of the feeding frame 501. The drug discharge nozzle 503 is provided at the bottom end of the feeding frame 501;

[0032] The outer surface of the fermentation tank 1 is provided with an insulation component 6; a drain port 7 is provided at the front end of the bottom of the fermentation tank 1, and a diversion component 8 is installed at the front end of the drain port 7. Specifically, the fermentation tank 1 is also called a "sludge fermentation anaerobic tank". The working principle of the fermentation tank 1 is mainly to decompose organic matter into gases such as methane and carbon dioxide and new cell substances through the action of anaerobic microorganisms, and generate energy at the same time. The working principle of the sludge fermentation anaerobic tank can be divided into the following steps: Water inlet stage: The sewage is pumped into the reactor, and the rotating motor 3 is turned on to drive the rotating knife 4 to evenly stir the fermentation tank 1 at the bottom end of the card cover 2. In the bacterial culture stage, the card cover 2 is opened, and an appropriate amount of bacterial strain is added to the reactor of the fermentation tank 1, and photosynthetic Bacteria can be cultured, and photosynthetic bacteria can also be added to the feeding rack 501 through the feeding component 5 at the upper end of the card cover 2, and closed and sealed through the closing cover 502, and evenly discharged into the interior of the fermentation tank 1 by using the discharge nozzle 503 for uniform distribution treatment, which greatly improves the working efficiency of the fermentation tank 1 in uniformly feeding the material, thereby reducing the frequency of the rotating knife 4 stirring the material, and the material is fermented inside the fermentation tank 1. The material inside the fermentation tank 1 can be evenly heated through the heat preservation component 6, which greatly improves the heat preservation of each group of fermentation tanks 1. The heat preservation component 6 is designed as a freely detachable structure, which is convenient for the user to disassemble and install the heating wire plate 603 on the upper end of different fermentation tanks 1. To carry out uniform heating treatment on different fermentation tanks 1, a heating wire plate 603 is connected to the upper end of the snap plate 601 and the slot seat 602, which is engaged with the inside of the slot seat 602 through the snap plate 601, and is penetrated by the fixing screws 604 in the middle of the snap plate 601 and the slot seat 602, so that it is locked on the barrel handles on both sides of the fermentation tank 1 for positioning and locking. A drain port 7 is provided at the bottom end of the fermentation tank 1 to facilitate the discharge of materials. A diversion component 8 is provided to reduce the speed of material discharge, thereby avoiding excessive discharge of materials inside the fermentation tank 1, causing the drain port 7 of the fermentation tank 1 to be affected by pressure, increasing the discharge burden of the drain port 7, thereby reducing the speed of material discharge from the drain port 7, and passing through the front end of the drain port 7. A diversion pipe 801 is provided to reduce the pressure carried by the excessively fast material discharge speed, and the material discharge is slowed down by two sets of drainage pipes 802. This technical solution solves the problem that uneven material addition to the sludge fermentation anaerobic tank will lead to uneven material distribution in the tank, with excessively high material concentration in some areas and too low in some areas, thereby affecting the uniformity and efficiency of the entire fermentation process, which may lead to poor fermentation effect, incomplete degradation of organic matter, and affect the quality and yield of the final product. The fermentation tank 1 is also called the "sludge fermentation anaerobic tank". The working principle of the fermentation tank 1 is mainly to decompose organic matter into gases such as methane and carbon dioxide and new cell substances through the action of anaerobic microorganisms, while generating energy.The working principle of the sludge fermentation anaerobic tank can be divided into the following steps: water inlet stage: sewage is pumped into the reactor, and by turning on the rotary motor 3, the rotary blade 4 is driven to evenly stir the fermentation tank 1 at the bottom of the card cover 2. In the bacterial culture stage, the card cover 2 is opened, and an appropriate amount of bacterial strain is added to the reactor of the fermentation tank 1, and photosynthetic bacteria are added for cultivation. The photosynthetic bacteria can also be added to the feeding rack 501 through the feeding component 5 at the upper end of the card cover 2, and closed and sealed through the closing cover 502. The discharge nozzle 503 is used to evenly discharge the inside of the fermentation tank 1 for uniform distribution, which greatly improves the working efficiency of the fermentation tank 1 in uniformly feeding the material, thereby reducing the frequency of the rotary blade 4 stirring the material, and the material is fermented inside the fermentation tank 1.

[0033] A step further, such as Figure 1 、 Figure 3 and Figure 4 As shown: it also includes an insulation component 6 including a snap plate 601, a slot seat 602, a heating wire plate 603 and a fixing screw 604. The snap plate 601 is provided on the right side of the fermentation tank 1, and the slot seat 602 is provided on the left side of the fermentation tank 1. The upper ends of the snap plate 601 and the slot seat 602 are connected with the heating wire plate 603. The middle of the snap plate 601 and the slot seat 602 is penetrated with a fixing screw 604. The advantage of this technical solution is that the material inside the fermentation tank 1 can be evenly heated by the insulation component 6, which greatly improves the heat preservation of each group of fermentation tanks 1. The warming component 6 is designed as a freely detachable structure, which is convenient for the user to disassemble and install the heating wire plate 603 on the upper end of different fermentation tanks 1, so as to carry out targeted and uniform heating treatment on different fermentation tanks 1. The heating wire plate 603 is connected to the upper end of the snap plate 601 and the slot seat 602, and is engaged with the inside of the slot seat 602 through the snap plate 601. The fixing screws 604 are passed through the middle of the snap plate 601 and the slot seat 602 to lock it on the barrel handles on both sides of the fermentation tank 1 for positioning and locking. A drain port 7 is provided at the bottom end of the fermentation tank 1 to facilitate the discharge of materials.

[0034] The above solutions also have the problem of not being able to quickly discharge the discharge port. Figure 1 As shown in the figure: In this solution, the diverter assembly 8 includes a diverter pipe 801 and a drain pipe 802. The diverter pipe 801 is installed at the front end of the drain port 7, and the drain pipes 802 are connected to both sides of the front end of the diverter pipe 801. By providing the diverter assembly 8, the speed of material discharge is reduced, and the material inside the fermenter 1 is prevented from being discharged too quickly, which would cause the drain port 7 of the fermenter 1 to be affected by pressure, increase the discharge burden of the drain port 7, and thus reduce the speed of material discharge from the drain port 7. By providing the diverter pipe 801 at the front end of the drain port 7, the pressure caused by the excessive discharge speed of the material is reduced, and the material discharge is slowed down by the two sets of drain pipes 802.

[0035] Working principle:

[0036] like Figure 1-4 As shown:

[0037] The fermentation tank 1 is also called a "sludge fermentation anaerobic tank". The working principle of the fermentation tank 1 is mainly to decompose organic matter into gases such as methane, carbon dioxide and new cell substances through the action of anaerobic microorganisms, and generate energy at the same time. The working principle of the sludge fermentation anaerobic tank can be divided into the following steps: water inlet stage: sewage is pumped into the reactor by a pump, and the rotating motor 3 is turned on to drive the rotating knife 4 to evenly stir the fermentation tank 1 at the bottom of the card cover 2. In the bacterial culture stage, the card cover 2 is opened, and an appropriate amount of bacterial strain is added to the reactor of the fermentation tank 1, and photosynthetic bacteria are added for cultivation. The photosynthetic bacteria can also be added to the feeding rack 501 through the feeding component 5 at the upper end of the card cover 2, and closed and sealed by the closing cover 502. The drug discharge nozzle 503 is evenly discharged into the interior of the fermentation tank 1 for even distribution, which greatly improves the working efficiency of the fermentation tank 1 for evenly feeding materials, thereby reducing the frequency of stirring of the material by the rotating knife 4. The material is fermented inside the fermentation tank 1, and the material inside the fermentation tank 1 can be evenly heated by the insulation component 6. The heat preservation of each group of fermentation tanks 1 is greatly improved. The heat preservation component 6 is designed as a freely detachable structure, which is convenient for the user to remove and install the heating wire plate 603 on the upper end of different fermentation tanks 1, and to carry out uniform heating treatment on different fermentation tanks 1 in a targeted manner. The upper end of the snap plate 601 and the slot seat 602 are connected with the heating wire plate 603. The snap plate 601 is snapped into the inside of the slot seat 602, and the fixing screws 604 are passed through the middle of the snap plate 601 and the slot seat 602 to lock it on the barrel handles on both sides of the fermentation tank 1 for fixed heating. The fermentation tank 1 is locked in position, and a drain outlet 7 is provided at the bottom end thereof to facilitate the discharge of materials. A diverter component 8 is provided to reduce the speed of material discharge, and to avoid excessive discharge of materials inside the fermentation tank 1, which causes the drain outlet 7 of the fermentation tank 1 to be affected by pressure, and the discharge burden of the drain outlet 7 to increase, thereby reducing the speed of material discharge from the drain outlet 7. A diverter pipe 801 is provided at the front end of the drain outlet 7 to reduce the pressure carried by excessive material discharge, and the material discharge is slowed down by two sets of drain pipes 802.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
