Description

TECHNICAL FIELD

[0001] The present application relates to the field of sewage treatment equipment, and particularly relates to an environment-friendly domestic sewage treatment equipment. BACKGROUND

[0002] Domestic sewage, as a key source of water pollution, mainly comes from the waste water generated by daily activities of residents such as washing clothes, bathing, cooking and defecating. These waste water will be treated by a special sewage treatment equipment, aiming at removing the pollutants therein until the preliminary environmental emission standard is reached, so as to minimize the negative impact on the environment after discharge, thereby playing an environmental protection role.

[0003] In domestic sewage, due to daily bathing activities, hair is often mixed. When the sewage enters the sewage treatment equipment for treatment, although a part of the hair can be intercepted by the preliminary filtration link, with the passage of time, the hair is easy to entangle on the filter structure, so that the equipment maintenance personnel have to frequently stop the equipment and regularly clean the filter structure, increasing the complexity of sewage treatment.

[0004] To solve the above problems, an environment-friendly domestic sewage treatment equipment is provided in the present application. SUMMARY

[0005] To solve the problem of hair entanglement in the background art which requires regular cleaning of the treatment equipment and increases the complexity, the present application provides an environment-friendly domestic sewage treatment equipment. In order to effectively solve the problem of hair in domestic sewage, the present application introduces a hair cleaning mechanism to collect and capture hair from sewage. After completing the hair capture, the hair is automatically separated to prepare for the next capture operation, and cooperates with the cleaning mechanism to discharge the hair, thereby reducing the need for manual intervention.

[0006] To solve the above problems, the present application provides an environment-friendly domestic sewage treatment equipment, which comprises a semicircular treatment cylinder, a flocculation treatment mechanism and a filter mechanism which treat the sewage in sequence. The inside of the semicircular treatment cylinder is rotatably provided with a rotating cylinder. The middle part of the rotating cylinder is provided with a notched column. The notched column is provided with a notched area along the length direction thereof. One end of the notched column rotatably extends to the outside of the rotating cylinder and is fixedly connected with the semicircular treatment cylinder.

[0007] The rotating cylinder is provided with a hair cleaning mechanism. The hair cleaning mechanism is connected with the outer periphery of the notched column through a self-adapting mechanism. The rotating cylinder is power-connected with a driving piece.

[0008] When the driving member drives the rotating drum to rotate, the hair cleaning mechanism is self-adapted to the change of the outer periphery of the notch column by the self-adapting mechanism, and performs the stretching and shrinking actions to have a first position state and a second position state. When the first position state, the hair cleaning mechanism is unfolded outside the rotating drum to fish the hair. When the second position state, the hair cleaning mechanism is shrunk to the inside of the rotating drum to clean the hair to the outer periphery of the rotating drum.

[0009] The driving member is matched with the scraping mechanism for cleaning the outer periphery of the rotating drum.

[0010] Preferably, the hair cleaning mechanism comprises a sleeve, an inclined block, a hanging rod and a top block. The sleeve is sleeved on the rotating drum. The inclined block is located inside the sleeve. The inclined block is connected with the sleeve through a restoring member, so that the inclined blocks are folded together when the top block is removed from pressing the inclined blocks. One end of the hanging rod is fixedly connected with the inclined block. The other end of the hanging rod is slidably extended outside the sleeve. The inside of the rotating drum is fixedly sleeved with a limiting tube located outside the sleeve.

[0011] Preferably, the restoring member comprises a spring one, a sliding block and a guide rod. One end of the sleeve away from the notch column is provided with a guide groove. The spring one and the sliding block are located inside the guide groove. One end of the spring one is fixedly connected with the guide groove. The other end is connected with the inclined block through the sliding block.

[0012] Preferably, the self-adapting mechanism comprises a notch ring, a connecting rod, a resisting rod, a spring two, an arc-shaped sheet and a spring three. The notch ring is fixedly connected with the notch column through the connecting rod. The plurality of notch rings are distributed at equal intervals. The resisting rod passes through the area between every two adjacent notch rings. The notch ring is formed with a notch, which is correspondingly arranged with the notch area on the notch column. One end of the resisting rod is slidably matched with the outer periphery of the notch column. The other end is slidably extended into the inside of the sleeve and is fixedly connected with the top block. The spring three is movably sleeved on the outer periphery of the resisting rod. One end of the spring three is fixedly connected with the inner wall of the sleeve. The other end is fixedly connected with the top block. The arc-shaped sheet is fixedly sleeved on the sleeve and is slidably matched with the notch ring. The arc-shaped sheet is connected with the inner wall of the rotating drum through the spring two.

[0013] Preferably, the end of the resisting rod close to the notch column is provided with a rolling member, which is rollingly connected with the outer periphery of the notch column.

[0014] Preferably, the driving member comprises a driving motor, a driving bevel gear and a driven bevel gear. The driven bevel gear is connected with the rotating drum shaft through a rotating shaft. The driving motor is fixedly installed on the semicircular processing drum. The driving end of the driving motor is driven through the driving bevel gear and the driven bevel gear.

[0015] Preferably, the scraping mechanism includes a scraper for scraping the outer periphery of the rotating drum, wherein the scraper has an upward-facing overlapping edge on both sides and is inclined downward.

[0016] Preferably, the scraping mechanism further includes a reciprocating screw, a moving table, and a rotating bevel gear. The rotating bevel gear is fixedly connected to the reciprocating screw and drives the driven bevel gear. An mounting block is fixedly installed on the semi-circular processing cylinder. The mounting block is rotatably connected to the rotating bevel gear through a rotating rod. The moving table is threaded onto the reciprocating screw. A cleaning plate is slidably arranged inside the scraper. A rotating block is fixedly connected to the cleaning plate. A linkage rod is rotatably connected to the rotating block through a rotating rod. A guide block that slides with the scraper is fixedly connected to the linkage rod. A torsion spring is provided between the linkage rod and the rotating block. The linkage rod is fixedly connected to the moving table. A blocking member for unidirectional flipping of the rotating block is provided on the overlapping edge of the scraper.

[0017] Preferably, the blocking member includes a stop block and a torsion spring shaft, and a storage groove is provided in the overlapping edge of the scraper. The stop block is rotatably connected to the storage groove through the torsion spring shaft.

[0018] Preferably, the flocculation treatment mechanism includes a treatment tank and a stirring component. The treatment tank is fixedly connected to a semi-circular treatment cylinder, the stirring component is disposed on the treatment tank, and a material outlet is provided on one side of the treatment tank.

[0019] The filtration mechanism includes a filter tank, a filter screen, and an operation window. The filter tank is fixed to the bottom of the treatment tank, the operation window is located on one side of the filter tank, and the filter screen is installed obliquely inside the filter tank.

[0020] The bottom of the semi-circular treatment cylinder, treatment tank, and filtration tank are all equipped with solenoid valves.

[0021] The above-described technical solution of the present invention has the following beneficial technical effects:

[0022] The drive unit rotates the drum, while the hair removal mechanism and the self-adaptive mechanism work together to move along the outer periphery of the notch column. When the hair removal mechanism moves out of the drum, it unfolds to capture hair in the sewage. After capturing the hair, the hair removal mechanism returns to the inside of the drum as it rotates. During this process, the captured hair automatically detaches from the cleaning mechanism, achieving a self-cleaning effect. This allows the hair removal mechanism to be ready for the next retrieval. At the same time, the hair is separated from the cleaning mechanism for easier subsequent processing. This process not only improves cleaning efficiency but also reduces manual intervention, making the entire cleaning process more convenient.

[0023] After the hair removal mechanism completes its retrieval, it detaches the captured hair onto the outer circumference of the rotating drum. At this point, the scraping mechanism intervenes to scrape the hair off the outer circumference of the rotating drum and collects it onto the scraping mechanism. The scraping mechanism is also driven by a drive unit. It can not only scrape the hair but also perform self-cleaning. Through its own movement, it detaches the collected hair to continue the scraping operation, ensuring the continuous operation of the scraping mechanism. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0036] Reference Figure 1 and Figure 6 An environmentally friendly domestic sewage treatment device includes a semi-circular treatment cylinder 1 for sewage treatment, a flocculation treatment mechanism 2, and a filtration mechanism 3. The flocculation treatment mechanism 2 includes a treatment tank 21 and a stirring component 22. In order to perform energy storage treatment on the sewage inside the semi-circular treatment cylinder 1, the treatment tank 21 is fixedly connected to the semi-circular treatment cylinder 1. The stirring component 22 is set on the treatment tank 21. A feed inlet 211 is provided on one side of the treatment tank 21. Flocculant can be added to the inside of the treatment tank 21 through the feed inlet 211 and stirred and mixed by the stirring component 22 to perform flocculation treatment. The filtration mechanism 3 includes a filter tank 31, a filter screen 32, and an operation window 33. The filter tank 31 is fixed to the bottom of the treatment tank 21. The operation window 33 is set on one side of the filter tank 31, so that the inside of the filter tank 31 can be manually intervened. In order to further treat the sewage discharged from the treatment tank 21, the filter screen 32 is installed at an angle inside the filter tank 31 to perform the filtering function.

[0037] In order to allow the liquid inside the semi-circular treatment cylinder 1, treatment tank 21 and filter tank 31 to be discharged, a solenoid valve 10 is provided at the bottom of the semi-circular treatment cylinder 1, treatment tank 21 and filter tank 31.

[0038] Reference Figure 1 , Figure 2 and Figure 4 The semi-circular processing cylinder 1 has a rotating cylinder 4 inside, and a notched column 5 is provided in the middle of the rotating cylinder 4. The notched column 5 has a notched area along its length. One end of the notched column 5 extends to the outside of the rotating cylinder 4 and is fixedly connected to the semi-circular processing cylinder 1. A turntable 11 is fixedly fitted on the notched column 5 and is rotatably connected to the semi-circular processing cylinder 1.

[0039] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 10 To capture hair, a hair cleaning mechanism 6 is provided on the rotating drum 4. The hair cleaning mechanism 6 includes a sleeve 61, an inclined block 62, a hanging rod 63, and a top block 64. The sleeve 61 is slidably sleeved on the rotating drum 4 (when the sleeve 61 enters the rotating drum 4, its outer end is adapted to the outer circumferential arc surface of the rotating drum 4). The inclined block 62 is located inside the sleeve 61. The inclined block 62 is connected to the sleeve 61 through a return member so that when the top block 64 (the top block 64 is provided with an inclined surface that cooperates with the inclined block 62) releases its pressure on the inclined block 62, the inclined blocks 62 close together (multiple inclined blocks 62 are provided, and the multiple inclined blocks 62 are evenly distributed in a circular area, and the number of inclined surfaces of the top block 64 is the same as the number of inclined blocks 62). One end of the hanging rod 63 is fixedly connected to the inclined block 62, and the other end of the hanging rod 63 slides out of the sleeve 61. A limiting tube 68 located outside the sleeve 61 is fixedly installed inside the rotating drum 4.

[0040] Reference Figure 4 and Figure 5 To facilitate the return of the tilted blocks 62 after they separate, the return component includes a spring 65. Figure 5 The sleeve 61 contains spring 65 in its ultimate tension state, slider 66, and guide rod 67. A guide groove 611 is provided at the end of the sleeve 61 away from the notch post 5. Spring 65 and slider 66 are located inside the guide groove 611. One end of spring 65 is fixedly connected to the guide groove 611, and the other end is connected to the inclined block 62 through slider 66. When the top block 64 acts on the inclined block 62, the inclined blocks 62 move away from each other. The movement of the inclined block 62 drives slider 66 to stretch and store energy in spring 65. When the top block 64 releases its pressure on the inclined block 62, spring 65 returns to its original state, so as to drive the inclined blocks 62 to move closer to each other. At this time, the hanging rod 63 enters the interior of the sleeve 61.

[0041] Reference Figure 1 , Figure 3 , Figure 4 and Figure 7The hair removal mechanism 6 is connected to the outer periphery of the notched post 5 via a self-adaptive mechanism 7. The self-adaptive mechanism 7 includes a notched ring 71, a connecting rod 72, a stop rod 73, a second spring 74, an arc-shaped piece 75, and a third spring 76. The notched ring 71 is fixedly connected to the notched post 5 via the connecting rod 72. Several notched rings 71 are evenly spaced, and each pair of adjacent notched rings 71 forms an area through which the stop rod 73 passes. Notches are formed on the notched rings 71, and the notches correspond to the notched areas on the notched post 5. One end of the stop rod 73 slides against the outer periphery of the notched post 5, and the other end slides out. The sleeve 61 is inserted into the sleeve and fixedly connected to the top block 64. The third spring 76 is movably sleeved on the outer periphery of the abutment 73. One end of the third spring 76 is fixedly connected to the inner wall of the sleeve 61 and the other end is fixedly connected to the top block 64. The arc-shaped piece 75 is fixedly sleeved on the sleeve 61 and slides with the notch ring 71. The arc-shaped piece 75 is connected to the inner wall of the rotating cylinder 4 through the second spring 74. When the arc-shaped piece 75 is limited by the notch ring 71, the second spring 74 is in a compressed state. When the arc-shaped piece 75 is not limited by the notch ring 71, the second spring 74 drives the sleeve 61 to retract into the rotating cylinder 4.

[0042] To increase the smoothness of contact between the abutment 73 and the notch ring 71, a rolling element is provided on the end of the abutment 73 near the notch post 5, and the rolling element is in rolling connection with the outer periphery of the notch post 5. The rolling element is a ball or a roller. When a roller is selected, the roller frame is fixedly connected to the abutment 73; when a ball is selected, the ball is rotatably sleeved in the end of the abutment 73 near the notch post 5.

[0043] Reference Figure 1 and Figure 3 The rotating drum 4 is powered by a drive unit 8, which includes a drive motor 81, a driving bevel gear 82, and a driven bevel gear 83. The driven bevel gear 83 is axially connected to the rotating drum 4 via a rotating shaft. The drive motor 81 is fixedly mounted on the semi-circular processing drum 1, and the drive end of the drive motor 81 is driven by the driving bevel gear 82 and the driven bevel gear 83. When the drive unit 8 drives the rotating drum 4 to rotate, the hair cleaning mechanism 6 is affected by the self-adapting mechanism 7 and changes in the outer periphery of the self-adapting notch post 5, so as to have a first position state and a second position state. In the first position state, the hair cleaning mechanism 6 is extended and located outside the rotating drum 4 to retrieve hair. In the second position state, the hair cleaning mechanism 6 is retracted to the inside of the rotating drum 4 to clean the hair to the outer periphery of the rotating drum 4.

[0044] Reference Figure 1 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10The drive unit 8 is connected to a scraping mechanism 9 for cleaning the outer periphery of the rotating drum 4. The scraping mechanism 9 includes a scraper 91 for scraping the outer periphery of the rotating drum 4. The scraper 91 has two upward-facing edges on both sides and is inclined downward. The scraper 91 scrapes the outer periphery of the rotating drum 4 and the end of the sleeve 61.

[0045] Furthermore, the scraping mechanism 9 also includes a reciprocating screw 92, a moving stage 93, and a rotating bevel gear 94. The rotating bevel gear 94 is fixedly connected to the reciprocating screw 92 and drives the driven bevel gear 83. A mounting block 95 is fixedly installed on the semi-circular processing cylinder 1. The mounting block 95 is rotatably connected to the rotating bevel gear 94 through a rotating rod 96. The moving stage 93 is threaded onto the reciprocating screw 92. A cleaning plate 97 is slidably arranged inside the scraper 91. The drive motor 81 drives the reciprocating screw 92 to rotate through the driving bevel gear 82, the driven bevel gear 83, and the rotating bevel gear 94, so that the moving stage 93 drives the cleaning plate 97 to reciprocate along the inclined direction of the scraper 91 to remove hair from the scraper 91. The cleaning plate 97 is fixedly connected to a rotating block 98. The rotating block 98 is rotatably connected to a linkage rod 910 via a rotating rod 99. A guide block 913, which slides with the scraper 91, is fixedly connected to the linkage rod 910. The guide block 913 is a right-angle guide block. A guide groove is provided on the side of the scraper 91 for guiding the movement of the guide block 913. A torsion spring 911 is provided between the linkage rod 910 and the rotating block 98. The linkage rod 910 is fixedly connected to the moving table 93. A blocking member is provided on the overlapping edge of the scraper 91 to prevent the rotating block 98 from flipping in one direction. There are multiple sets of blocking members, and the multiple sets of blocking members are equally spaced. The unidirectional rotation of the rotating block 98 causes the cleaning plate 97 to flip during the process of moving back to the rotating drum 4.

[0046] The blocking component includes a stop block 912 and a torsion spring shaft 914. A storage groove 901 is provided inside the overlapping edge of the scraper 91. The stop block 912 is rotatably connected to the storage groove 901 via the torsion spring shaft 914 (the torsion spring shaft 914 consists of a shaft and a torsion spring sleeved on the outer circumference of the shaft; the stop block 912 is rotatably connected to the storage groove 901 via the shaft; the torsion spring is movably sleeved on the outer circumference of the shaft; one end of the torsion spring is fixedly connected to the inner wall of the storage groove 901; and the other end of the torsion spring is fixedly connected to the stop block 912). Under the action of the torsion spring shaft 914 (the torque of the torsion spring shaft 914 is less than the torque of the torsion spring 911), the rotating block 98 is moved away from the torsion spring shaft 914. When the rotating block 98 moves away from the rotating drum 4, the rotating block 98 enters the storage tank 901 through the stop block 912. The cleaning plate 97 scrapes the hair out of the scraper 91. When the rotating block 98 and the cleaning plate 97 return to the rotating drum 4, the stop block 912 is tilted and blocked by the torsion spring shaft 914. When the stop block 912 is blocked by the storage tank 901 and can no longer rotate, the cleaning plate 97 continues to contact the stop block 912. Under the action of the torsion spring 911, the cleaning plate 97 flips over, so that the cleaning plate 97 can no longer scrape the hair inside the scraper 91 and returns to the rotating drum 4, thus achieving the effect of one-way scraping.

[0047] Working principle: The driving component 8 drives the rotating drum 4 to rotate, which in turn drives the hair cleaning mechanism 6 and the self-adaptive mechanism 7 to rotate along the outer edge of the notched post 5. The abutment rod 73 responds to the change in the outer edge of the notched post 5 by contacting and pressing the inclined block 62 to generate action. Due to the presence of the limiting tube 68 and the rotating drum 4, they restrict the movement of the hanging rod 63 in the length direction. At the same time, with the pressing action of the abutment rod 73, the sleeve 61 is pushed out of its original position in advance, so that the hanging rod 63 leaves the blocking area formed by the limiting tube 68 and the rotating drum 4. Then, the abutment rod 73 causes the inclined block 62 to expand through the action of the top block 64, thereby driving the hanging rod 63 to extend out of the sleeve 61 to reach a fully extended state. In this extended state, the hanging rod 63 will cooperate with the rotation of the rotating drum 4 to capture the hair inside the semi-circular processing cylinder 1, thereby achieving the cleaning of the hair inside the semi-circular processing cylinder 1.

[0048] When the hair removal mechanism 6 successfully captures the hair inside the semi-circular processing cylinder 1 and rotates with the continuous rotation of the semi-circular processing cylinder 1, the abutment rod 73 automatically adapts to the changes in the outer periphery of the notched post 5. When the abutment rod 73 moves to the concave area of ​​the notched post 5, the notched ring 71 restricts the position of the sleeve 61. At this time, the abutment rod 73 will be subjected to the restoring force of the spring 74, which will cause the top block 64 to release the pressure on the inclined block 62 in advance, so that the various parts of the inclined block 62 gradually move closer together, thereby causing the hanging rod 63 to be retracted into the inside of the sleeve 61. During this process, the hanging rod 6... The hair grabbed by the rod 73 will be separated. As the rod 73 continues to move along the outer periphery of the notch post 5, when the notch ring 71 releases the limit on the sleeve 61, the restoring force of the spring 74 will come into play again, causing the sleeve 61 to be retracted into the inside of the rotating drum 4. In this way, the hair remaining on the sleeve 61 will be cleaned onto the outer periphery of the rotating drum 4. At this time, in conjunction with the scraping mechanism 9, it can scrape and clean the outer periphery of the rotating drum 4 and the end of the sleeve 61, thereby effectively reducing the hair entanglement on the processing equipment, reducing the need for manual intervention, and increasing the convenience of the whole process.
