Description

Technical Field

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

[0002] Domestic sewage, as a key source of water body pollution, mainly comes from the wastewater generated by residents' daily activities such as washing clothes, taking baths, cooking, and using toilets. These wastewaters will be treated by special sewage treatment equipment to remove the pollutants therein until they initially meet the environmental protection discharge standards, so as to ensure that the negative impact on the environment after discharge is minimized, thus playing an environmental protection role.

[0003] In domestic sewage, due to daily bathing activities, there are often hairs mixed in. When these sewage enter the sewage treatment equipment for treatment, although a part of the hairs can be intercepted in the initial filtration link, over time, the hairs are extremely easy to wind around the filtration structure, forcing the equipment maintenance personnel to frequently stop the equipment and regularly clean the filtration structure, increasing the complexity of sewage treatment.

[0004] To solve the above problems, an environment-friendly domestic sewage treatment equipment is proposed in this application. Summary of the Invention

[0005] To solve the problem in the background art that the hair-winding treatment equipment needs to be regularly cleaned, increasing the complexity, the present invention proposes an environment-friendly domestic sewage treatment equipment. In order to effectively solve the problem of hairs in domestic sewage, a hair cleaning mechanism is introduced to collect and capture hairs from the sewage. After the hairs are captured, they are automatically separated to prepare for the next capture operation, and work together with the cleaning mechanism to discharge the hairs, thereby reducing the need for manual intervention.

[0006] To solve the above problems, the present invention provides an environment-friendly domestic sewage treatment equipment, including a semi-circular treatment cylinder, a flocculation treatment mechanism, and a filtration mechanism for treating sewage in sequence.

One end of the notch column rotates and extends to the outside of the rotating cylinder and is fixedly connected to the semi-circular treatment cylinder; A hair cleaning mechanism is provided on the rotating cylinder. The hair cleaning mechanism is connected to the outer periphery of the notch column through a self-adapting mechanism. The rotating cylinder is power-connected to a driving member; When the driving member drives the rotating cylinder to rotate, the hair cleaning mechanism is affected by the self-adapting mechanism and adapts to the change of the outer periphery of the notch column, and performs stretching and contracting actions, so as to have a first position state and a second position state. In the first position state, when the hair cleaning mechanism is unfolded outside the rotating cylinder, it salvages hair.

The first spring and the slider are located inside the guide groove. One end of the first spring is fixedly connected to the guide groove, and the other end is connected to the inclined block through the slider.

[0009] Preferably, the self-adapting mechanism includes a notch ring, a connecting rod, a resisting rod, a second spring, an arc-shaped piece and a third spring. The notch ring is fixedly connected to the notch column through the connecting rod. A plurality of notch rings are equidistantly distributed. A region through which the resisting rod passes is formed between every two adjacent notch rings. A notch is formed on the notch ring, and the notch is correspondingly arranged with the notch region on the notch column. One end of the resisting rod is slidably matched with the outer periphery of the notch column, and the other end slides into the inside of the sleeve and is fixedly connected to the top block. The third spring is movably sleeved on the outer periphery of the resisting rod. One end of the third spring is fixedly connected to the inner wall of the sleeve, and the other end is fixedly connected to the top block. The arc-shaped piece is fixedly sleeved on the sleeve and is slidably matched with the notch ring, and the arc-shaped piece is connected to the inner wall of the rotating cylinder through the second spring.

[0010] Preferably, a rolling member is provided at one end of the resisting rod close to the notch column, and the rolling member is in rolling connection with the outer periphery of the notch column.

[0011] Preferably, the driving member includes a driving motor, a driving bevel gear and a driven bevel gear. The driven bevel gear is axially connected to the rotating cylinder through a rotating shaft. The driving motor is fixedly installed on the semi-circular processing cylinder, and the driving end of the driving motor is in transmission with the driven bevel gear through the driving bevel gear.

[0012] Preferably, the scraping mechanism comprises a scraper for scraping the outer circumference of the drum, and the scraper has overlapping edges formed on both sides thereof and is arranged to face downward in an inclined manner.

[0013] Preferably, the scraping mechanism also includes a reciprocating screw, a moving platform and a rotating bevel gear, the rotating bevel gear is fixedly connected to the reciprocating screw and transmits power to the driven bevel gear, a mounting block is fixedly installed on the semicircular processing cylinder, the mounting block is rotatably connected to the rotating bevel gear through a rotating rod, the moving platform is threadedly sleeved on the reciprocating screw, a cleaning plate is slidingly provided inside the scraper, the cleaning plate is fixedly connected to a rotating block, the rotating block is rotatably connected to a linkage rod through a rotating rod, a guide block slidingly matched with the scraper is fixedly connected to the linkage rod, a torsion spring is arranged between the linkage rod and the rotating block, the linkage rod is fixedly connected to the moving platform, and a blocking member for one-way flipping of the rotating block is provided on the mounting edge of the scraper.

[0014] Preferably, the blocking member includes a blocking block and a torsion spring shaft, a storage groove is provided in the lap edge of the scraper, and the blocking block is rotatably connected to the storage groove via the torsion spring shaft.

[0016] The above technical solution of the present invention has the following beneficial technical effects: The driving member drives the drum to rotate, and at the same time, the hair cleaning mechanism cooperates with the self-adaptive mechanism to move along the outer circumference of the notched column. When the hair cleaning mechanism is removed from the drum, it is unfolded to capture hair in the sewage. After the capture is completed, the hair cleaning mechanism returns to the inside of the drum along with the rotation of the drum. During this process, the captured hair will automatically separate from the cleaning mechanism to achieve a self-cleaning effect, so that the hair cleaning mechanism can be prepared for the next salvage. At the same time, the hair is separated from the cleaning mechanism to facilitate subsequent processing. This process not only improves the cleaning efficiency, but also reduces manual intervention, making the entire cleaning process more convenient.

[0017] After the hair cleaning mechanism finishes the salvage operation, the captured hair will be detached onto the outer periphery of the rotating drum. At this time, the scraping mechanism intervenes to scrape the hair on the outer periphery of the rotating drum and collect the hair onto the scraping mechanism. The scraping mechanism is also driven by a driving member, which can not only scrape the hair but also perform self-cleaning. By its own movement, the collected hair is detached to enable continuous scraping operation, ensuring the continuous operation of the scraping mechanism. Description of the Drawings

In order to re-treat the sewage discharged from the interior of the treatment tank 21, the filter screen 32 is inclined and installed inside the filtration tank 31 to play a role in filtration.

[0031] In order to enable the liquids inside the semi-circular treatment cylinder 1, the treatment tank 21 and the filtration tank 31 to be discharged, solenoid valves 10 are provided at the bottoms of the semi-circular treatment cylinder 1, the treatment tank 21 and the filtration tank 31.

[0032] Referring to Figure 1 、 Figure 2 and Figure 4 , a rotating cylinder 4 is rotatably arranged inside a semi-circular processing cylinder 1. A notched column 5 is arranged in the middle of the rotating cylinder 4. The notched column 5 is provided with a notched area along its length direction. One end of the notched column 5 rotatably 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 sleeved on the notched column 5, and the turntable 11 is rotatably sleeved with the semi-circular processing cylinder 1; Referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 10 , in order to capture hair, a hair cleaning mechanism 6 is arranged on the rotating cylinder 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 cylinder 4 (when the sleeve 61 enters the rotating cylinder 4, its outer end is adapted to the outer circumferential arc surface of the rotating cylinder 4). The inclined block 62 is located inside the sleeve 61. The inclined block 62 is connected to the sleeve 61 through a restoring member, so that when the top block 64 (the top block 64 is provided with an inclined surface cooperating with the inclined block 62) releases the pressing on the inclined block 62, the inclined blocks 62 close to each other (a plurality of inclined blocks 62 are provided, and the plurality of inclined blocks 62 are evenly distributed in a circular area. 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 outside of the sleeve 61. A limiting tube 68 located outside the sleeve 61 is fixedly sleeved inside the rotating cylinder 4.

[0033] Referring to Figure 4 and Figure 5 , in order to facilitate the restoration of the inclined blocks 62 after separation from each other, the restoring member includes a first spring 65 ( Figure 5 the state of the first spring 65 in

[0034] Referring to Figure 1 、 Figure 3 、 Figure 4 and Figure 7The hair cleaning mechanism 6 is connected to the outer periphery of the notched column 5 through the self-adaptive mechanism 7. The self-adaptive mechanism 7 includes a notched ring 71, a connecting rod 72, a push rod 73, a second spring 74, an arc piece 75 and a third spring 76. The notched ring 71 is fixedly connected to the notched column 5 through the connecting rod 72. A plurality of notched rings 71 are evenly spaced. A plurality of notched rings 71 are adjacent to each other to form an area through which the push rod 73 passes. A notch is formed on the notched ring 71, and the notch is corresponding to the notch area on the notched column 5. One end of the push rod 73 is slidably matched with the outer periphery of the notched column 5, and the other end is slidably extended. The arc piece 75 is inserted into the interior of the sleeve 61 and is fixedly connected to the top block 64. The spring three 76 is movably sleeved on the outer periphery of the push rod 73. One end of the spring three 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 piece 75 is fixedly sleeved on the sleeve 61 and slidably fits with the notch ring 71, and the arc piece 75 is connected to the inner wall of the rotating drum 4 through the spring two 74. When the arc piece 75 is limited by the notch ring 71, the spring two 74 is in a compressed state, so that when the arc piece 75 is not limited by the notch ring 71, the spring two 74 drives the sleeve 61 to be retracted into the inside of the rotating drum 4.

[0035] In order to increase the smoothness of the contact between the support rod 73 and the notch ring 71, a rolling member is provided on the end of the support rod 73 close to the notch column 5, and the rolling member is rollingly connected to the outer periphery of the notch column 5. The rolling member is a ball or a roller. When a roller is selected, the roller frame is fixedly connected to the support rod 73; when a ball is selected, the ball is rotatably sleeved in the end of the support rod 73 close to the notch column 5.

[0036] Reference Figure 1 and Figure 3 The rotary drum 4 is connected to a driving member 8, which includes a driving motor 81, an active bevel gear 82 and a driven bevel gear 83. The driven bevel gear 83 is axially connected to the rotary drum 4 through a rotating shaft. The driving motor 81 is fixedly mounted on the semicircular processing drum 1, and the driving end of the driving motor 81 is transmitted through the active bevel gear 82 and the driven bevel gear 83. When the driving member 8 drives the rotary drum 4 to rotate, the hair cleaning mechanism 6 is self-adapted to the changes in the outer periphery of the notched column 5 by the self-adaptive mechanism 7, and performs extension and contraction actions to have a first position state and a second position state. In the first position state, the hair cleaning mechanism 6 is unfolded and located outside the rotary drum 4 to salvage hair. In the second position state, the hair cleaning mechanism 6 is retracted to the inside of the rotary drum 4 to clean the hair to the outer periphery of the rotary drum 4.

[0037] Reference Figure 1 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10, a scraping mechanism 9 for the outer periphery of the cleaning rotating cylinder 4 is cooperatively connected to the driving member 8. The scraping mechanism 9 includes a scraping plate 91 for scraping the outer periphery of the rotating cylinder 4. The two sides of the scraping plate 91 form a placing edge upwards and are arranged obliquely downwards. The scraping plate 91 serves to scrape the outer periphery of the rotating cylinder 4 and the end of the sleeve 61.

[0038] Furthermore, the scraping mechanism 9 further includes a reciprocating lead screw 92, a moving table 93 and a rotating bevel gear 94. The rotating bevel gear 94 is fixedly connected to the reciprocating lead screw 92 and is in transmission with the driven bevel gear 83. An installation block 95 is fixedly installed on the semi-circular processing cylinder 1. The installation block 95 is rotatably connected to the rotating bevel gear 94 through a rotating rod 96. The moving table 93 is threadedly sleeved on the reciprocating lead screw 92. A cleaning plate 97 is slidably arranged inside the scraping plate 91. The driving motor 81 is in transmission through the driving bevel gear 82, the driven bevel gear 83 and the rotating bevel gear 94 to drive the reciprocating lead screw 92 to rotate, so that the moving table 93 drives the cleaning plate 97 to reciprocate along the inclined direction of the scraping plate 91 to clean the hair on the scraping plate 91. The cleaning plate 97 is fixedly connected with a rotating block 98. The rotating block 98 is rotatably connected with a linkage rod 910 through a rotating rod 99. A guide block 913 slidably matched with the scraping plate 91 is fixedly connected to the linkage rod 910. The guide block 913 is a right-angle guide block. A guide groove for the guiding movement of the guide block 913 is provided on the side of the scraping plate 91. A torsion spring 911 is arranged 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 for one-way flipping of the rotating block 98 is arranged on the placing edge of the scraping plate 91. The number of the blocking members is multiple groups, and the multiple groups of blocking members are arranged at equal intervals. The one-way rotation of the rotating block 98 causes the cleaning plate 97 to flip during the process of the cleaning plate 97 moving back to the rotating cylinder 4.

[0039] The blocking member includes a stopper 912 and a torsion spring rotating shaft 914. A storage groove 901 is formed in the placing edge of the scraping plate 91. The stopper 912 is rotatably connected to the storage groove 901 through the torsion spring rotating shaft 914 (the torsion spring rotating shaft 914 includes a rotating shaft and a torsion spring sleeved on the outer periphery of the rotating shaft. The stopper 912 is rotatably connected to the storage groove 901 through the rotating shaft, the torsion spring is movably sleeved on the outer periphery of the rotating 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 stopper 912). Under the action of the torsion spring rotating shaft 914 (the torsion force of the torsion spring rotating shaft 914 is less than the torsion force of the torsion spring 911), when the rotating block 98 moves away from the rotating cylinder 4, the rotating block 98 acts on the stopper 912 to enter the inside of the storage groove 901, and the cleaning plate 97 scrapes out the hair inside the scraping plate 91. When the rotating block 98 and the cleaning plate 97 return to the position of the rotating cylinder 4, the stopper 912 is in an inclined blocking state under the action of the torsion spring rotating shaft 914. Then, when the stopper 912 is blocked by the storage groove 901 and cannot rotate anymore, the cleaning plate 97 continuously contacts the stopper 912. Under the action of the torsion spring 911, the cleaning plate 97 flips, so that the cleaning plate 97 cannot act on the scraping inside the scraping plate 91 and returns to the position of the rotating cylinder 4, thus achieving the function of one-way scraping.

[0040] Working principle: The driving member 8 drives the rotating cylinder 4 to rotate, driving the hair cleaning mechanism 6 and the self-adapting mechanism 7 to rotate along the outer edge of the notch column 5. The abutting rod 73 will respond to the change of the outer edge of the notch column 5 and generate an action by contacting and pressing the inclined block 62. Due to the existence of the limiting tube 68 and the rotating cylinder 4, they limit the moving position of the hanging rod 63 in the length direction. At the same time, under the pressing action of the abutting rod 73, the sleeve 61 will be 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 cylinder 4. Then, the abutting rod 73 causes the inclined block 62 to expand through the action of the top block 64, and further drives 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 action of the rotating cylinder 4 to capture the hair inside the semi-circular processing cylinder 1, thus realizing the cleaning of the hair inside the semi-circular processing cylinder 1.

[0041] When the hair cleaning 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 abutting rod 73 will automatically adapt to the changes in the outer circumference of the notch column 5. When the abutting rod 73 moves to the concave area of the notch column 5, since the notch ring 71 restricts the position of the sleeve 61, at this time, the abutting rod 73 will be subjected to the restoring force of the second spring 74, thereby driving the top block 64 to release the pressure on the inclined block 62 in advance, causing the various parts of the inclined block 62 to gradually approach each other, and thus driving the hanging rod 63 to be retracted into the sleeve 61. During this process, the hair grasped by the hanging rod 63 will be separated. As the abutting rod 73 continues to move along the outer circumference of the notch column 5, when the notch ring 71 releases the limit on the sleeve 61, the restoring force of the second spring 74 will act again, driving the sleeve 61 to be retracted into the inner part of the rotating cylinder 4. In this way, the remaining hair on the sleeve 61 will be cleaned onto the outer circumference of the rotating cylinder 4. At this time, by cooperating with the scraping mechanism 9, it can scrape and clean the outer circumference of the rotating cylinder 4 and the end of the sleeve 61, thereby effectively reducing the entanglement of hair on the processing equipment, reducing the need for manual intervention, and increasing the convenience of the whole process.

Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
