Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an anaerobic granular sludge internal circulation reactor. Background Technology

[0002] The anaerobic granular sludge internal circulation reactor is an internally automated wastewater treatment reactor consisting of two UASB reactors connected in series. However, the existing anaerobic granular sludge internal circulation reactor still has shortcomings. Specifically, the filter equipment installed at the outlet of the existing anaerobic granular sludge internal circulation reactor is generally fixed and inconvenient to disassemble and replace.

[0003] Therefore, an anaerobic granular sludge internal circulation reactor is needed to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an anaerobic granular sludge internal circulation reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anaerobic granular sludge internal circulation reactor includes a reactor body, a filter mechanism is fixedly connected to the outlet of the reactor body, and a drain pipe is installed on the top of the filter mechanism.

[0007] The filtration mechanism includes a fixed sleeve fixedly connected to the outer wall of the reactor body. A mounting frame is slidably connected inside the fixed sleeve. An adsorption plate is fixedly connected inside the mounting frame. A filter screen is fixedly connected inside the mounting frame near the adsorption plate. A drive shaft is rotatably connected inside the mounting frame to the front, back, and sides of the adsorption plate. A locking block is fixedly connected to the outer wall of the drive shaft within the mounting frame. Baffles are fixedly connected to the inner wall of the fixed sleeve above and below the locking block. A sealing gasket is fixedly connected to the outer wall of the baffle near the mounting frame. A spiral spring is fixedly connected to the center of the outer wall of the drive shaft. A transmission gear is fixedly connected to the outer wall of the drive shaft above the locking block. A ring-shaped rack is meshed with the outer wall of the transmission gear within the mounting frame. An adjusting plate is fixedly connected to the top of the ring-shaped rack.

[0008] As a preferred embodiment of this invention, the reactor body is an anaerobic internal circulation reactor.

[0009] As a preferred embodiment of this utility model, the fixing sleeve, mounting frame, baffle, locking block, and adjusting plate are all made of aluminum alloy. The locking block and adjusting plate both penetrate and extend outside the mounting frame. The spiral spring is fixedly connected to the fixing sleeve.

[0010] As a preferred embodiment of this utility model, the adsorption plate is made of activated carbon plate, and multiple sets of filter screen, adsorption plate, baffle and sealing gasket are provided. The connection between the adjustment plate, the annular rack and the mounting frame is a rotatable connection.

[0011] As a preferred embodiment of this utility model, the sealing gasket is made of silicone, and the connection method of the baffle, the mounting frame and the card block is sliding connection.

[0012] As a preferred embodiment of this utility model, the height of the card block is adapted to the distance between adjacent baffles, and the shape of the adsorption plate and the filter screen is adapted to the shape of the mounting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs an anaerobic granular sludge internal circulation reactor. The filtration mechanism within this device filters and treats the outflowing clean water. Wastewater is injected into the reactor body, where it is treated. The resulting clean water flows into a fixed sleeve. Inside the fixed sleeve, the water passes through an adsorption plate and a filter screen before flowing out. The adsorption plate, made of activated carbon, absorbs harmful substances in the clean water, while the filter screen removes impurities. To replace the adsorption plate and filter screen, the fixed sleeve is disassembled, and an adjusting plate is rotated. The adjusting plate drives a transmission gear via a ring rack. The rotating transmission gear drives a locking block to rotate inward via a drive shaft. The inwardly rotating locking block enters the mounting frame, and the block no longer holds the mounting frame. The mounting frame is then pulled out of the fixed sleeve, allowing for the replacement of the adsorption plate and filter screen within the mounting frame. This convenient replacement and disassembly operation solves the problem that existing anaerobic granular sludge internal circulation reactors typically have fixed filtration equipment at the outlet, making disassembly and replacement inconvenient.

[0024] An anaerobic granular sludge internal circulation reactor includes a reactor body 1, a filter mechanism 2 fixedly connected to the outlet of the reactor body 1, and a drain pipe 3 installed on the top of the filter mechanism 2.

[0025] Reactor body 1 is an anaerobic internal circulation reactor;

[0026] In this embodiment, reference Figure 2 and Figure 3The filtration mechanism 2 includes a fixed sleeve 201 fixedly connected to the outer wall of the reactor body 1. A mounting frame 202 is slidably connected inside the fixed sleeve 201. An adsorption plate 203 is fixedly connected inside the mounting frame 202. A filter screen 204 is fixedly connected inside the mounting frame 202 near the adsorption plate 203. A drive shaft 205 is rotatably connected inside the mounting frame 202, to the front, back, and sides of the adsorption plate 203. A locking block 206 is fixedly connected to the outer wall of the drive shaft 205 inside the mounting frame 202. A baffle 207 is fixedly connected to the inner wall of the fixed sleeve 201, above and below the locking block 206. A sealing gasket 208 is fixedly connected to the outer wall of the baffle 207 near the mounting frame 202. A spiral spring 209 is fixedly connected to the center of the outer wall of the drive shaft 205. A transmission gear 210 is fixedly connected to the outer wall of the drive shaft 205 above the locking block 206. A ring rack 211 is meshed with the outer wall of the transmission gear 210 inside the mounting frame 202. An adjusting plate 212 is fixedly connected to the top of the ring rack 211.

[0027] The fixed sleeve 201, mounting frame 202, baffle 207, locking block 206, and adjusting plate 212 are all made of aluminum alloy. The locking block 206 and adjusting plate 212 extend through and beyond the mounting frame 202. The spiral spring 209 is fixedly connected to the fixed sleeve 201. The adsorption plate 203 is made of activated carbon. Multiple sets of the filter screen 204, adsorption plate 203, baffle 207, and sealing gasket 208 are provided. The adjusting plate 212, ring rack 211, and mounting frame 202 are rotatably connected. The sealing gasket 208 is made of silicone. The baffle 207, mounting frame 202, and locking block 206 are slidably connected. The height of the locking block 206... The distance between adjacent baffles 207 is adapted to the shape of the adsorption plate 203 and filter screen 204, which is adapted to the shape of the mounting frame 202.

The clean water entering the fixed sleeve 201 passes through the adsorption plate 203 and the filter screen 204 in sequence before flowing out through the drain pipe 3. The adsorption plate 203, made of activated carbon, can absorb harmful substances in the clean water, and the filter screen 204 can remove impurities from the clean water. When it is necessary to replace the adsorption plate 203 and the filter screen 204, the drain pipe 3 is removed, and the adjusting plate 212 is rotated. The adjusting plate 212 drives the transmission gear 210 to rotate through the ring rack 211. The rotating transmission gear… 210 drives the locking block 206 to rotate inward via the drive shaft 205. The inwardly rotating locking block 206 enters the mounting frame 202 and no longer locks the mounting frame 202. Pull the mounting frame 202 to remove it from the fixed sleeve 201. Replace the adsorption plate 203 and filter screen 204 inside the mounting frame 202. After replacement, put the mounting frame 202 back into the fixed sleeve 201. Loosen the adjusting plate 212. The spiral spring 209 drives the drive shaft 205 to rotate in the opposite direction. The reverse-rotating drive shaft 205 drives the locking block 206 to rotate outward. The locking block 206 inserts between the baffles 207 and locks the mounting frame 202. Reinstall the mounting frame 202 in the fixed sleeve 201.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
