Description

Technical Field

[0001] This invention relates to a wastewater treatment device, and more particularly to a high-efficiency contact reaction biological rotating disc wastewater treatment device. Background Technology

[0002] A biological rotating disc is a biological treatment structure consisting of a water tank and a rotating disc partially submerged in wastewater. It mainly includes a rotating disc (disc body), a contact reaction tank, a rotating shaft, and a drive device. If necessary, a protective cover can be installed above the oxidation tank to provide shelter from wind and rain and heat preservation. A biofilm for filtration is attached to the disc. The reaction takes place in a reaction tank that matches the disc. The sludge produced after the reaction accumulates at the bottom of the reaction tank and is discharged through a drain outlet at the bottom of the reaction tank.

[0003] Existing biological rotating discs typically use microbial attachment plates perpendicular to the water flow direction. Wastewater can easily pass between adjacent attachment plates, and the flow obstruction is not significant. The wastewater relies on natural flow to impact and adsorb onto the attachment plates. When the distance between two attachment plates is large, the amount of wastewater impacting the plates decreases. Densely packed attachment plates also hinder wastewater flow, thus reducing purification efficiency. Furthermore, wastewater passing through the sedimentation tank still contains silt, which tends to settle at the bottom of the rotating chamber, affecting the plate rotation. High-concentration wastewater also tends to settle at the bottom of the rotating chamber, creating a large gap between the attachment plates and the bottom of the chamber, which is not conducive to intercepting and purifying the high-concentration wastewater at the bottom. The bacterial solution inside the attachment plates needs to be added beforehand, and there is usually no mid-process addition mechanism. Also, different types of bacteria are required depending on the pollutant ions, making it difficult to add different bacterial solutions mid-process for different pollutants. Summary of the Invention

[0004] The purpose of this invention is to provide a highly efficient contact reaction biological rotating disc wastewater treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency contact reaction biological rotating disc wastewater treatment device, comprising a shell, a purification mechanism connected to the shell, the purification mechanism including a rotating cavity, the rotating cavity being located in the middle of the shell, a rotating shaft being rotatably connected to the shell, a plurality of fixed rollers being fixedly connected to one end of the rotating shaft located inside the rotating cavity, the fixed rollers being equipped with concentric mounting rings, a plurality of attachment plates being installed between the fixed rollers and the mounting rings, an adding mechanism being connected to the shell, the adding mechanism including a storage cavity, the storage cavity being located inside the fixed rollers, a plurality of discharge cavities being located on the outer wall of the fixed rollers, a conduit being installed on the fixed rollers for communication between the discharge cavities and the attachment plates, a communication port being located on the inner wall of the fixed rollers for communication between the discharge cavities and the storage cavity, a closing block being slidably connected to the fixed rollers inside the discharge cavities, a spring being installed on the fixed rollers inside the discharge cavities, the spring being used to push the closing block to block the communication port, and a rotating roller being rolled inside the fixed rollers inside the storage cavity for contacting the closing block.

[0006] In a preferred embodiment of the present invention, the attachment plate is a sponge plate, and the attachment plate is fixed at an angle.

[0007] The above technical solution facilitates the attachment of bacteria and also helps to block the flow of sewage.

[0008] As a preferred embodiment of the present invention, the shell is provided with a first sedimentation tank and a second sedimentation tank at both ends, and the shell is provided with a water inlet between the first sedimentation tank and the rotating cavity.

[0009] The above technical solutions facilitate the sedimentation of wastewater and the removal of silt.

[0010] As a preferred embodiment of the present invention, a motor is installed at one end of the housing, and the rotating shaft is installed on the output end of the motor.

[0011] The above technical solution facilitates the rotation of the rotating shaft, thereby driving the attachment plate to move.

[0012] As a preferred embodiment of the present invention, a cleaning mechanism is connected to the housing, the cleaning mechanism includes a spiral rod, the spiral rod is rotatably connected to the bottom end of the housing located in the rotating cavity, a belt is wound between the spiral rod and the rotating shaft, one end of the spiral rod extends into the interior of the first sedimentation tank, and a rubber strip is fixedly connected to the edge of the spiral rod, the rubber strip abutting against the housing.

[0013] The above technical solution facilitates the discharge of silt from the bottom of the rotating chamber and allows for the recirculation of concentrated wastewater from the bottom of the rotating chamber, thereby increasing the wastewater purification effect.

[0014] As a preferred embodiment of the present invention, the housing is provided with a plurality of partitions inside the rotating cavity. The partitions are in the shape of annulus and are located between two adjacent fixed rollers.

[0015] The above technical solution serves to impede the flow of wastewater, preventing it from passing through the attachment plate too quickly.

[0016] As a preferred embodiment of the present invention, a plug is screwed onto the fixed roller, the storage cavity is connected to the outside through the plug, and the plug is provided with air holes.

[0021] The above technical solution facilitates the opening and closing of the closing block.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention, by setting up an attachment plate and a rotating chamber, facilitates the sedimentation of silt at the bottom of the rotating chamber. The attachment plate is inclined, so that when rotating, it slowly pushes the water flow towards the first sedimentation tank, thereby slowing down the movement of the water flow and allowing the attachment plate to have better impact with the water flow. The attachment plate is pre-inoculated with purifying bacteria, which facilitates the purification of sewage. The attachment plate is used for the reproduction of bacteria.

[0024] 2. This invention, by setting up a rotating roller, a closing block, a conduit, and a spring, allows for the addition of bacterial solution when bacteria need to be replenished. The plug can be unscrewed to add bacterial solution to the inside of the fixed roller. As the fixed roller rotates, the rotating roller inside it rolls, pressing the closing block at the bottom of the fixed roller. The spring is compressed, and the bacterial solution enters the discharge chamber and slowly flows into the attachment plate through the conduit, thus replenishing the bacteria and increasing wastewater purification. Furthermore, it facilitates the timely addition of the corresponding bacterial solution when treating different types of wastewater to meet the purification requirements.

[0025] 3. By setting up a belt, a screw rod, and a rubber strip, the present invention drives the screw rod to rotate during the rotation of the rotating shaft, which in turn drives the rubber strip to rotate. The screw rod can discharge the sludge inside the rotating chamber into the first sedimentation tank. At the same time, it facilitates the backflow of high-concentration sewage at the bottom of the rotating chamber, thereby reducing the purification load on the attachment plate and ensuring the purification effect of the sewage.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-7 This invention provides a technical solution for a highly efficient contact reaction biological rotating disc wastewater treatment device:

[0036] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a high-efficiency contact reaction biological rotating disc wastewater treatment device includes a shell 1, a purification mechanism 2 connected to the shell 1, the purification mechanism 2 including a rotating cavity 29, the rotating cavity 29 is provided in the middle of the shell 1, a rotating shaft 24 is rotatably connected to the shell 1, and a plurality of fixed rollers 25 are fixedly connected to one end of the rotating shaft 24 located inside the rotating cavity 29. The fixed rollers 25 are equipped with concentric mounting rings 28, and a plurality of attachment plates 27 are installed between the fixed rollers 25 and the mounting rings 28.

[0037] Furthermore, the attachment plate 27 is a sponge plate, and the attachment plate 27 is fixed at an angle, which facilitates the reproduction of bacteria. At the same time, the inclined attachment plate 27 can obstruct the flow of sewage when it rotates, increasing the contact between sewage and the attachment plate 27.

[0038] Furthermore, the shell 1 is provided with a first sedimentation tank 21 and a second sedimentation tank 23 at both ends, and the shell 1 is provided with an inlet 22 between the first sedimentation tank 21 and the rotating chamber 29, so as to facilitate the sedimentation of silt in the sewage.

[0039] Furthermore, a motor 26 is installed at one end of the housing 1, and a rotating shaft 24 is installed on the output end of the motor 26, thereby facilitating the movement of the attachment plate 27.

[0040] Furthermore, multiple baffles 4 are installed inside the rotating cavity 29 of the housing 1. The baffles 4 are in the shape of a ring and are located between two adjacent fixed rollers 25. The baffles 4 play a role in blocking the flow and preventing sewage from passing through the attachment plate 27 quickly.

[0041] according to Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, a high-efficiency contact reaction biological rotating disc wastewater treatment device includes an addition mechanism 5 connected to the shell 1. The addition mechanism 5 includes a storage chamber 53. The storage chamber 53 is located inside a fixed roller 25. The outer wall of the fixed roller 25 is provided with multiple discharge chambers 54. A conduit 57 is installed on the fixed roller 25 to connect the discharge chambers 54 and the attachment plate 27. The inner wall of the fixed roller 25 is provided with a communication port 59 to connect the discharge chambers 54 and the storage chamber 53. A closing block 55 is slidably connected to the fixed roller 25 inside the discharge chamber 54. A spring 56 is installed inside the fixed roller 25 inside the discharge chamber 54. The spring 56 is used to push the closing block 55 to block the communication port 59. A rotating roller 58 is rolled inside the storage chamber 53 of the fixed roller 25 to abut against the closing block 55.

[0042] Furthermore, a plug 52 is screwed onto the fixed roller 25, and the storage cavity 53 is connected to the outside through the plug 52. The plug 52 is provided with air holes 51, which facilitates the addition of bacterial liquid.

[0043] Furthermore, the closing block 55 has a triangular structure and is made of rubber, so that it blocks the discharge chamber 54 when it does not come into contact with the rotating roller 58, thus preventing the rapid discharge of bacterial liquid and its loss with sewage.

[0044] Furthermore, the rotating roller 58 has a cylindrical structure and is made of metal, which facilitates the movement of the closing block 55.

[0045] according to Figure 1 , Figure 3 and Figure 5 As shown, a high-efficiency contact reaction biological rotating disc wastewater treatment device has a cleaning mechanism 3 connected to the shell 1. The cleaning mechanism 3 includes a screw rod 32. The screw rod 32 is rotatably connected to the bottom end of the shell 1 located in the rotating cavity 29. A belt 31 is wound and connected between the screw rod 32 and the rotating shaft 24. One end of the screw rod 32 extends into the interior of the first sedimentation tank 21.

[0046] Furthermore, a rubber strip 33 is fixedly connected to the edge of the spiral rod 32. The rubber strip 33 abuts against the housing 1, thereby facilitating the automatic cleaning of the mud and sand at the bottom of the rotating cavity 29, and at the same time, the high-concentration sewage at the bottom is returned.

[0047] In practical use, wastewater is introduced into the first sedimentation tank 21, where silt settles. The motor 26 drives the rotating shaft 24, which in turn rotates the fixed roller 25, the attachment plate 27, and the mounting ring 28. The clear liquid from the upper layer of the first sedimentation tank 21 enters the rotating chamber 29 through the inlet 22, where it is blocked by the baffle 4. This also facilitates sedimentation at the bottom of the rotating chamber 29. The attachment plate 27 is inclined, which, during rotation, slowly pushes the water flow towards the first sedimentation tank 21, slowing its movement and allowing for better impact between the attachment plate 27 and the water flow. The attachment plate 27 is pre-inoculated with purifying bacteria to facilitate wastewater purification. The attachment plate 27 is used for bacterial reproduction. The purified water slowly overflows into the second sedimentation tank 23 and is then discharged. When bacteria need to be added, the plug can be unscrewed. 52. The air vent 51 is used to balance the air pressure and add bacterial solution to the inside of the fixed roller 25. When the fixed roller 25 rotates, the rotating roller 58 inside the fixed roller 25 will roll. The rotating roller 58 presses the closing block 55 at the bottom of the fixed roller 25, and the spring 56 is compressed. The bacterial solution will enter the discharge chamber 54 and slowly enter the inside of the attachment plate 27 through the conduit 57, thereby completing the replenishment of bacteria and increasing the purification of sewage. At the same time, when treating different types of sewage, it is convenient to add the corresponding bacterial solution in time to meet the purification of sewage. During the rotation of the rotating shaft 24, the screw rod 32 will be driven to rotate through the belt 31, which will drive the rubber strip 33 to rotate. The screw rod 32 can discharge the sludge inside the rotating chamber 29 into the first sedimentation tank 21. At the same time, it is convenient to return the high-concentration sewage at the bottom of the rotating chamber 29, thereby reducing the purification load of the attachment plate 27 and ensuring the purification effect of sewage.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
