Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a mud-water separation device in sewage treatment. Background Art

[0002] With the rapid development of the global economy and the acceleration of urbanization, the discharge of industrial wastewater and domestic sewage has increased dramatically. If improperly treated sewage is discharged directly into natural water bodies, it will cause serious damage to the ecological environment and threaten human health and ecological balance. Therefore, efficient sewage treatment technology has become a core concern in the field of environmental protection.

[0003] As a common mud-water separation equipment, the decanter centrifuge has been widely used in the field of sewage treatment. It can separate most solid particles from sewage in a relatively short time, which to a certain extent reduces the load of subsequent treatment. However, the decanter centrifuge can only quickly separate most solid particles with larger particle sizes. It cannot effectively remove or treat other pollutants such as dissolved gases and harmful microorganisms in sewage. The mud water that has been initially treated by the decanter centrifuge must be further treated.

The invention separates the residual sewage in the mixed sewage by pressing the material, the movement of the electric push rod drives the movement of the second scissor-type bracket, and the intersection of the first scissor-type bracket and the second scissor-type bracket realizes the lowering of the bottom pressing plate, and the pressing plate is engaged with the trough at the top of the material holding chassis, so that the pressing plate directly enters the interior of the trough, and filters the mixed sewage in the trough by pressure, and presses out the residual water inside by pressure and discharges it through the bottom, thereby achieving a more complete separation of the mixed sewage.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Example 1, as Figure 1-3 As shown, a mud-water separation device for sewage treatment includes an outer shell 1, a separation component 2 is installed inside the outer shell 1, a connecting component 3 is provided on the left side of the outer shell 1, a swing-pushing component 4 is provided on the rear side of the connecting component 3, an aeration component 5 is provided on the right side of the swing-pushing component 4, an adsorption component 6 is provided on the front side of the swing-pushing component 4, an extrusion component 8 is provided on the right side of the aeration component 5, and a cleaning component 7 is provided on the upper side of the separation component 2.

[0022] Therefore, this solution simultaneously processes the water and mud separated by the horizontal screw centrifuge 23 through the cooperation of various components. Among them, the aeration component 5 and the adsorption component 6 are used to comprehensively treat the water surface from the two aspects of aeration and oxygenation and impurity collection, providing the necessary oxygen conditions for the biochemical treatment of sewage, promoting the decomposition of organic matter in sewage, and effectively improving the quality of sewage treatment. The mud is simultaneously squeezed by the squeezing component 8 to reduce its water content, thereby improving the treatment depth of the mud and water of the entire sewage treatment system, making the treated product more in line with environmental protection and subsequent treatment requirements.

[0023] Example 2: Based on Example 1, this example is to achieve the effect of comprehensive treatment of the water surface from two aspects: aeration and oxygenation and impurity collection.

[0024] See Figure 1-9 The outer shell 1 includes a feed port 11, a base 12 is fixedly connected to the lower end of the outer shell 1, a water outlet 13 is provided on the left side of the lower end of the outer shell 1, a discharge port 14 is provided on the right side of the lower end of the outer shell 1, and a partition plate 15 is fixedly connected to the inside of the outer shell 1.

[0025] Specifically, the partition plate 15 can separate the separated mud and water.

[0026] See Figure 3 The separation component 2 includes a support base 21 fixedly connected to the left side of the outer shell 1, a through groove 211 is provided on the outer surface of the support base 21, a motor 22 is fixedly installed on the upper end of the support base 21, and the output end of the motor 22 is fixedly connected to the horizontal screw centrifuge 23, a water outlet 24 is provided on the right side of the lower end of the horizontal screw centrifuge 23, and a material outlet 25 is provided on the left side of the lower end of the horizontal screw centrifuge 23.

[0027] Furthermore, the through groove 211 facilitates the passage of the pulley drive group 1 31. The above-mentioned decanter centrifuge 23 is a conventional technical means in the prior art, and its specific working principle is as follows: The horizontal screw centrifuge 23 mainly consists of a drum and a screw conveyor. When the equipment is started, the drum rotates at high speed, forming a strong centrifugal force field inside. This centrifugal force can be hundreds or even thousands of times greater than gravity. After the mud-water mixture enters the drum from the feed port 11, under the action of centrifugal force, due to the different densities of the mud solid particles and water, different centrifugal sedimentation rates are generated. The dense mud particles are thrown toward the inner wall of the drum by the centrifugal force, and gradually settle on the inner wall of the drum to form a mud layer; while the water with lower density is inside the mud layer, forming an inner water ring; The screw conveyor rotates in the same direction as the drum but at a different speed. It scrapes the mud off the inner wall of the drum and transports it along the axial direction of the drum to the water outlet 24 at the small end of the drum for discharge. The water in the inner water ring flows out through the discharge port 25 at the large end of the drum, thus achieving the separation of mud and water.

[0028] Furthermore, the motor 22 and the horizontal screw centrifuge 23 pour the mud and water from the feed port 11, and the mud and water enter the horizontal screw centrifuge 23 for separation. The separated mud is discharged from the second water outlet 24, and the water is discharged from the second outlet 25.

[0029] See Figure 4 and Figure 5The connecting component 3 includes a pulley transmission group 31 fixedly connected to the output end of the motor 22, the outer surface of the pulley transmission group 31 is slidably connected to the through groove 211, the end of the pulley transmission group 31 away from the output end of the motor 22 is fixedly connected to the rotating shaft 32, the right end of the rotating shaft 32 is rotatably connected to the outer shell 1, the outer surface of the rotating shaft 32 is fixedly connected to the bevel gear transmission group 33, the end of the bevel gear transmission group 33 away from the rotating shaft 32 is rotatably connected to the connecting plate 34, and the right end of the connecting plate 34 is fixedly connected to the outer shell 1.

[0030] The pulley transmission group 1 31 mentioned above is composed of two pulleys of different diameters and a belt. Among them, the pulley connected to the rotating shaft 1 32 has a larger diameter, which makes the rotation speed of the rotating shaft 1 32 slower. The bevel gear transmission group 33 mentioned above is composed of two bevel gears that mesh with each other to change the direction of rotation.

[0031] The pulley transmission group 1 31 is driven by the output end of the motor 22 to rotate together. When the pulley transmission group 1 31 rotates, it drives the rotating shaft 1 32 to rotate, thereby driving the bevel gear transmission group 33 to rotate.

[0032] See Figure 5 and Figure 6 The swing push assembly 4 includes a connecting rod 1 411 fixedly connected to the rear end of the bevel gear transmission group 33, the end of the connecting rod 1 411 away from the bevel gear transmission group 33 is rotatably connected to the connecting rod 2 41, the outer surface of the connecting rod 1 411 is rotatably connected to the connecting plate 34, the end of the connecting rod 2 41 away from the connecting rod 1 411 is rotatably connected to the fan-shaped tooth 42, the end of the fan-shaped tooth 42 away from the connecting rod 2 41 is fixedly connected to the rotating shaft 2 43, the outer surface of the rotating shaft 2 43 is rotatably connected to the L-shaped support frame 44, and the upper end of the L-shaped support frame 44 is fixedly connected to the lower end of the support seat 1 21.

[0033] Furthermore, the bevel gear transmission group 33 will drive the connecting rod 1 411 to rotate continuously, and the connecting rod 1 411 will drive the connecting rod 2 41 to push up and down, and the right end of the sector tooth 42 is limited by the L-shaped support frame 44, so the connecting rod 2 41 can push the sector tooth 42 to swing back and forth with the rotating shaft 2 43 as the axis during movement.

[0034] Connecting rod 1 411 rotates in a circle along with bevel gear transmission group 33, and drives connecting rod 2 41 to swing during the rotation. Because the other end of connecting rod 2 41 is connected to sector teeth 42, connecting rod 2 41 can only perform reciprocating push-pull movements, thereby pulling sector teeth 42 to swing back and forth with rotating shaft 2 43 as the axis.

[0035] The lower end of the L-shaped support frame 44 is rotatably connected to a fixed shaft 46 near the side of the outer shell 1, the outer surface of the fixed shaft 46 is fixedly connected to gear 1 45, the front side of gear 1 45 is fixedly connected to gear 2 47, the outer surface of the sector tooth 42 is meshed with gear 1 45, the lower end of the L-shaped support frame 44 is slidably connected to a T-shaped limit seat 48, the lower end of the T-shaped limit seat 48 is fixedly connected to a rack 49, the outer surface of the rack 49 is meshed with gear 2 47, and the rack 49 is fixedly connected to a push rod 410 near the side of the outer shell 1.

[0036] The sector teeth 42 mentioned above can engage with gear 1 45 when swinging back and forth, causing gear 1 45 to rotate back and forth, and gear 1 45 will drive the fixed shaft 46 and gear 2 47 to rotate synchronously, so that gear 2 47 engages with the rack 49 and drives the rack 49 to move left and right, wherein the T-shaped limit seat 48 can limit the rack 49 so that the rack 49 can slide stably at the lower end of the L-shaped support frame 44.

[0037] The rack 49 will drive the push rod 410 to move together during the process of moving left and right.

[0038] See Figure 8 and Figure 9 The aeration assembly 5 includes a movable plate 51 fixedly connected to the right end of the push rod 410, a fixed plate 52 fixedly connected to the left side of the partition plate 15, a sliding groove 521 is provided on the outer surface of the fixed plate 52, and the outer surface of the movable plate 51 is slidably connected to the sliding groove 521. An air bag 53 is fixedly connected to the left end of the partition plate 15 and located on the upper side of the fixed plate 52, and the left end of the air bag 53 is fixedly connected to the movable plate 51.

[0039] Several one-way valves 54 are provided on the lower side of the left end of the movable plate 51. An air pipe is provided on the inner surface of the movable plate 51. The air pipe is fixedly connected to the left end of the airbag 53 through the movable plate 51. An air outlet valve is provided at the rear end of the airbag 53 and extends to the outer surface of the outer shell 1.

[0040] The movable plate 51 is driven by the push rod 410 to move left and right. During the movement, the movable plate 51 squeezes the airbag 53 to make it smaller, so that the air inside the airbag 53 is discharged from the one-way valve 54 through the air pipe inside the movable plate 51. The movable plate 51 also drives the one-way valve 54 to move synchronously, thereby increasing the dissolved oxygen content in the water from different positions. The released air forms bubbles in the water. During the rising process of the water, it can absorb and wrap suspended impurities in the sewage, causing these impurities to float to the water surface along with the bubbles. Among them, the air outlet valve extends to the outer surface of the outer shell 1. When the push rod 410 drives the movable plate 51 to move to the left, it will pull the airbag 53 to become larger, so that the air pressure inside the airbag 53 becomes smaller, and the external atmospheric pressure will push air into the airbag 53, absorbing fresh air from the outside through the air outlet valve, so as to replenish air for the airbag 53 in time and prepare for the next aeration and oxygenation, thereby ensuring the continuity and stability of the aeration process.

[0041] See Figure 4 and Figure 7 The adsorption component 6 includes a support seat 2 61 fixedly connected to the lower end of the support seat 1 21, the lower end of the support seat 2 61 is fixedly connected to a water bag 62, the outer surface of the front end of the rotating shaft 2 43 is fixedly connected to a swing plate 63, the upper end of the swing plate 63 is fixedly connected to the water bag 62, the right end of the water bag 62 is fixedly connected to a water suction pipe 64, the outer surface of the lower end of the water suction pipe 64 is fixedly connected to a limiting block 65, and the rear end of the limiting block 65 is fixedly connected to a float 66.

[0042] Furthermore, the swing plate 63 swings synchronously with the second rotating shaft 43. The water bag 62 changes its own air pressure as it swings, thereby absorbing and discharging water. A one-way valve is provided at the left end of the water bag 62 to discharge the sewage absorbed by the water bag 62 into the external sewage collection tank. The float 66 can automatically adjust its position according to the fluctuation of the water surface, ensuring that the water inlet of the suction pipe 64 connected thereto is always at the highest point of the water surface, so as to facilitate the absorption of impurities floating up from the water through the aeration assembly 5.

[0043] Furthermore, when the sector tooth 42 swings upward, gear 1 45 will rotate counterclockwise, causing the fixed shaft 46 and gear 2 47 to rotate in the same direction, thereby driving the rack 49 and the push rod 410 to move to the right, squeezing the movable plate 51 and the air bag 53, so that the one-way valve 54 injects fresh air into the water. Synchronously, when the sector tooth 42 swings upward, the rotating shaft 2 43 and the swing plate 63 swing upward synchronously. At this time, the swing plate 63 will squeeze the water bag 62, making the water bag 62 smaller, so that the waste water in the water bag 62 is discharged from the one-way valve at its left end. When the sector tooth 42 swings downward, the air bag 53 is absorbing fresh air from the outside. At this time, the swing plate 63 pulls the water bag 62 downward, making the water bag 62 larger, and the air pressure inside the water bag 62 changes, so that the water bag 62 absorbs the water at the top of the outer shell 1 through the suction pipe 64, and absorbs impurities floating on the water surface.

[0044] See Figure 9 The extrusion assembly 8 includes a sliding rod 81 fixedly connected to the upper end of the movable plate 51 , and the lower end of the sliding rod 81 is fixedly connected to the extrusion plate 82 .

[0045] The sliding rod 81 and the squeezing plate 82 move together with the moving plate 51 to simultaneously squeeze and dehydrate the mud to reduce the moisture content of the mud. A separate drain valve is provided on the rear side of the outer shell 1.

[0046] Therefore, this solution promotes the reciprocating motion of the air bag 53 in the aeration component 5 through the cooperation between the separation component 2, the connection component 3 and the swing push component 4, thereby releasing fresh air into the separated water, increasing the dissolved oxygen content in the water, and helping it to decompose and metabolize organic matter in the sewage. In addition, through the cooperation between the aeration component 5 and the adsorption component 6, the aeration component 5 causes the impurities to float, while the synergistic effect of the swing plate 63, the water bag 62 and the float 66 enables it to absorb impurities on the water surface in a timely manner, and comprehensively treats the water surface from two aspects: aeration and oxygenation and impurity collection, greatly improving the effect of sewage surface treatment, ensuring the cleanliness of the water surface and improvement of water quality, and simultaneously driving the extrusion component 8 to extrude the separated mud, thereby improving overall work efficiency.

[0047] Embodiment 3: Based on Embodiments 1 and 2, this embodiment aims to prevent the feed port 11 from being blocked.

[0048] See Figure 1 、 Figure 2 、 Figure 3 and Figure 10 The cleaning component 7 includes a pulley transmission group 2 72 fixedly connected to the output end of the motor 22, and the end of the pulley transmission group 2 72 away from the output end of the motor 22 is fixedly connected to a rotating shaft 3 71, the left end of the rotating shaft 3 71 is rotatably connected to the motor 22, and the right end of the rotating shaft 3 71 is fixedly connected to a bevel gear 1 73, the outer surface of the bevel gear 1 73 is meshed with a bevel gear 2 74, the inner surface of the bevel gear 2 74 is fixedly connected to a scraper 75, and the outer surface of the scraper 75 is rotatably connected to the feed port 11.

[0049] Specifically, the above-mentioned pulley transmission group 2 72 is composed of two pulleys and belts of different diameters, wherein the pulley connected to the rotating shaft 3 71 rotates more slowly, and the pulley transmission group 2 72 is driven to rotate by the output end of the motor 22, wherein the rotating shaft 3 71 can provide support for the pulley transmission group 2 72, and the rotating shaft 3 71 will drive the bevel gear 1 73 and the bevel gear 2 74 to engage when rotating, thereby driving the scraper 75 to rotate continuously along the inner surface of the feed port 11, scraping off the mud and water adhering to the feed port in time, effectively preventing the feed port from being blocked due to the accumulation of mud and water, and ensuring that the sewage can continuously and smoothly enter the horizontal screw centrifuge 23 for separation and treatment.

[0050] Therefore, this solution can timely scrape off the mud and water adhering to the inner surface of the feed port 11 by continuously rotating the scraper 75 in the feed port 11, effectively preventing the feed port 11 from being blocked due to the accumulation of mud and water, ensuring that the sewage can continuously and smoothly enter the decanter centrifuge 23 for separation and treatment, ensuring the continuity of the entire sewage treatment process, and reducing the additional pressure and wear on the decanter centrifuge 23 caused by poor feeding, which helps to extend the service life of the decanter centrifuge 23 and reduce equipment maintenance costs.

[0051] It should be noted that the specific installation method, circuit connection method and control method of the motor 22 and the decanter centrifuge 23 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
