Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically to a sludge hydrolysis acidification anaerobic reactor. Background Technology

[0002] The sludge hydrolysis acidification anaerobic reactor is one of the important pieces of equipment in wastewater treatment. It can decompose and transform the organic matter in sludge to purify water quality. It has the advantages of high treatment efficiency, low energy consumption, low sludge production, high organic load, and strong shock resistance. Therefore, it has been widely used in the field of wastewater treatment.

[0003] In the process of treating wastewater, if the sludge has strong flocculation properties or a certain degree of viscosity, it will cause the sludge to aggregate into clumps, forming larger particles that settle to the bottom. This results in incomplete decomposition and transformation of organic matter in the sludge, further affecting the wastewater treatment effect. Therefore, there is an urgent need for a sludge hydrolysis acidification anaerobic reactor to solve the above problems. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention aims to provide a sludge hydrolysis acidification anaerobic reactor to solve the problem mentioned in the background art that sludge will agglomerate, forming large particles and settling to the bottom.

[0005] To achieve the above objectives, the present invention provides a sludge hydrolysis acidification anaerobic reactor, comprising a tank body, wherein an inlet pipe and an outlet pipe are respectively provided at the upper and lower ends of the tank body, and a crushing mechanism is provided inside the tank body for crushing large particles of sludge that have settled to the bottom.

[0006] Furthermore, the crushing mechanism includes a rotating rod rotatably connected to the tank body. Multiple connecting plates are fixedly connected to one end of the rotating rod located inside the tank body. Each connecting plate is connected to a crushing plate via a telescopic assembly on the side near the bottom of the tank body. The tank body is provided with a drive mechanism for driving each crushing plate.

[0007] Furthermore, each of the connecting plates is fixedly connected to a baffle on the side opposite to the rotation direction of the rotating rod, and the baffle and the crushing plate are provided with multiple through holes.

[0008] Furthermore, the driving mechanism includes a fixed ring fixedly connected to the inner wall of the tank, a plurality of wedge-shaped blocks are arranged downward at the bottom of the fixed ring, and a driving rod is arranged on the crushing plate corresponding to the wedge-shaped blocks, with the upper end of the driving rod passing through the connecting plate and arranged upward.

[0009] Furthermore, the telescopic assembly includes: a drive ring provided on the side wall of the rotating rod corresponding to the crushing plate, two through holes provided on the upper part of the drive ring corresponding to the crushing plate, two T-shaped rods slidably connected in the through holes, and the lower ends of the two T-shaped rods connected to the crushing plate;

[0010] A return spring is fitted on each of the two T-shaped rods on the drive ring.

[0011] Furthermore, a motor is provided at the upper end of the tank, and the rotating rod extends upward through the tank and is connected to the motor for transmission.

[0012] Furthermore, the upper end of the drive rod is wedge-shaped or semi-circular to fit the wedge block.

[0013] Furthermore, the drive rod is a T-shaped rod, and the upper end of the drive rod is a wedge or semi-circle that matches the wedge block; a return spring is sleeved on the rod body between the upper end of the T-shaped rod and the connecting plate.

[0014] Furthermore, the drive ring and the connecting plate are integrally formed.

[0015] Furthermore, the working process of the crushing mechanism includes: in the process of decomposing and transforming the organic matter in the sludge, starting the motor to drive the rotating rod to rotate;

[0016] The rotating rod rotates and synchronously drives the crushing plate on one side of the connecting plate to rotate. During the rotation of the crushing plate, when the driving rod on the crushing plate abuts against the wedge block on the fixed ring, under the interaction force of the inclined plane and the guiding action of the telescopic component, the crushing plate will be pushed closer to the bottom wall of the tank. During the process of the crushing plate approaching the bottom wall of the tank, the large particles of sludge deposited on the bottom of the tank are squeezed and crushed.

[0017] When the drive rod passes the wedge block, under the elastic action of the telescopic component, it drives the crushing plate away from the bottom wall of the tank. With the continuous rotation of the rotating rod, the drive rod reciprocates against the wedge block. Thus, under the interaction force of the inclined plane and the guiding and resetting action of the telescopic component, the crushing plate reciprocates to squeeze and crush the large particles of sludge deposited on the bottom wall of the tank. When the large particles of sludge are not completely crushed, they cannot pass through the through hole and will be reciprocated by the crushing plate 203, thereby making the organic matter in the sludge fully mixed with the reactants. At the same time, the sludge is stirred during the rotation of the crushing plate 203 and the baffle 204.

[0018] This invention, through the setting of a crushing mechanism, drives the crushing plate to reciprocate and crush large particles of sludge deposited on the bottom wall of the tank under the driving action of the drive mechanism, thereby enabling the organic matter in the sludge to be fully mixed with the reactants, further ensuring the treatment effect of decomposition and transformation of organic matter in the sludge.

[0028] Example 1

[0029] Please see Figures 1-5 The sludge hydrolysis acidification anaerobic reactor shown in the figure includes a tank 101, with an inlet pipe 102 and an outlet pipe 103 respectively at the upper and lower ends of the tank 101, and also includes a crushing mechanism installed inside the tank 101 for crushing large particles of sludge that have settled to the bottom.

[0030] The crushing mechanism includes a rotating rod 201 rotatably connected to the tank body 101. One end of the rotating rod 201 located inside the tank body 101 is fixedly connected to a plurality of connecting plates 202. Each connecting plate 202 is connected to a crushing plate 203 via a telescopic assembly on the side near the bottom of the tank body 101. The tank body 101 is provided with a drive mechanism for driving each crushing plate 203. Each connecting plate 202 is fixedly connected to a baffle 204 on the side opposite to the rotation direction of the rotating rod 201. The baffle 204 and the crushing plate 203 are provided with a plurality of through holes 205.

[0031] It should be noted that: through the setting of the crushing mechanism, under the driving action of the drive mechanism, the crushing plate 203 is driven to reciprocate to squeeze and crush the large particles of sludge deposited on the bottom wall of the tank 101, thereby making the organic matter in the sludge fully mixed with the reactants, and further ensuring the treatment effect of decomposition and transformation of organic matter in the sludge.

[0032] Please see Figures 2-4 The driving mechanism shown in the figure includes a fixed ring 301 fixedly connected to the inner wall of the tank 101. A plurality of wedge blocks 302 are fixedly connected to the side of the fixed ring 301 near the rotating rod 201. Inclined surfaces 303 are provided on opposite sides of each wedge block 302. A driving rod 304 is fixedly connected to the side of the crushing plate 203 near the connecting plate 202. The other end of the driving rod 304 passes through the connecting plate 202 and slides on the side wall of each inclined surface 303.

[0033] It should be noted here that: through the setting of the drive mechanism, when the drive rod 304 on the crushing plate 203 abuts against the wedge block 302 on the fixed ring 301, under the interaction force of the inclined surface 303 and the guiding action of the telescopic component, the crushing plate 203 will be pushed to move closer to the bottom wall of the tank 101.

[0034] Please see Figure 4 The telescopic assembly shown in the figure includes a drive ring 402 connected to the side wall of the rotating rod 201 via multiple fixed plates 401. Two symmetrically arranged T-shaped rods 403 are slidably connected to the side wall of the drive ring 402. One end of the two T-shaped rods 403 is connected to the breaking plate 203. Springs 404 are sleeved on the side wall of the two T-shaped rods 403. The two ends of the two springs 404 are respectively connected to the side wall of the T-shaped rods 403 and the drive ring 402.

[0035] It should be noted here that the telescopic components provide guidance and reset for the movement of the broken plate 203.

[0036] The working principle for crushing large particles of sludge at the bottom is as follows: During the decomposition and transformation of organic matter in the sludge, the motor 5 is started to drive the rotating rod 201 to rotate. During the rotation of the rotating rod 201, the crushing plate 203 on one side of the connecting plate 202 will be rotated synchronously. During the rotation of the crushing plate 203, when the driving rod 304 on the crushing plate 203 abuts against the wedge block 302 on the fixed ring 301, under the interaction force of the inclined plane 303 and the guiding action of the telescopic component, the crushing plate 203 will be pushed closer to the bottom wall of the tank 101. During the process of the crushing plate 203 approaching the bottom wall of the tank 101, the large particles of sludge deposited on the bottom of the tank 101 will be squeezed and crushed.

[0037] When the drive rod 304 passes the wedge block 302, under the elastic action of the telescopic component, it will drive the crushing plate 203 away from the bottom wall of the tank 101. Therefore, as the rotating rod 201 continues to rotate, it will drive the drive rod 304 to reciprocate against the wedge block 302. Under the interaction force of the inclined plane 303 and the guiding and resetting action of the telescopic component, the crushing plate 203 will reciprocate to squeeze and crush the large particles of sludge deposited on the bottom wall of the tank 101. And through the setting of the baffle 204, when the large particles of sludge are not completely crushed, they will not be able to pass through the guide hole 205. At this time, they will still be squeezed and crushed by the reciprocating crushing plate 203, so that the organic matter in the sludge is fully mixed with the reactants, ensuring the treatment effect of decomposition and transformation of organic matter in the sludge. At the same time, during the rotation of the crushing plate 203 and the baffle 204, the sludge will be stirred, which can promote the contact between organic waste and microorganisms and prevent the deposition and accumulation of waste to a certain extent.

[0039] Please see Figure 2 This embodiment further illustrates Example 1. The upper end of the tank 101 in the figure is provided with a motor 5, and the output end of the motor 5 is connected to the rotating rod 201.

[0040] It should be noted here that the motor 5 is designed to facilitate the rotation of the rotating rod 201.

[0041] Example 3

[0042] As a variation of Embodiment 1, the driving rod is a T-shaped rod, and the upper end of the driving rod is a wedge or semi-circular shape adapted to the wedge block; a return spring is sleeved on the rod body between the upper end of the T-shaped rod and the connecting plate.

[0043] Example 4

[0044] As a variation of Embodiment 1, the drive ring and the connecting plate are integrally formed.
