Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to a sludge-water separation device in sewage treatment. BACKGROUND

[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 untreated sewage is directly discharged 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 the core concern in the field of environmental protection.

[0003] A horizontal screw centrifuge, as a common sludge-water separation device, has been widely used in the field of sewage treatment. It can separate most solid particles from sewage in a short time, to some extent, reducing the load of subsequent treatment. However, the horizontal screw centrifuge can only quickly separate most solid particles with large particle sizes. Other pollutants such as dissolved gases and harmful microorganisms in sewage cannot be effectively removed or treated, and the sludge-water after preliminary treatment by the horizontal screw centrifuge must be further treated.

The device separates residual sewage in mixed sewage by pressing. The movement of the electric push rod pushes the movement of the second scissor support. The intersection of the first and second scissor supports lowers the bottom pressing plate, which is embedded with the material holding groove on the top of the material holding box. Therefore, the pressing plate directly enters the inside of the holding groove, filters the mixed sewage in the holding groove by pressure, and presses out the residual water inside through the bottom, achieving more complete separation of the mixed sewage.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Therefore, this solution, through the cooperation of various components, simultaneously treats the water and sludge separated by the horizontal screw centrifuge 23. Among them, the aeration component 5 and the adsorption component 6 comprehensively treat the water surface from two aspects: aeration and oxygenation, and impurity collection. This provides the necessary oxygen conditions for the biochemical treatment of sewage, promotes the decomposition of organic matter in sewage, and effectively improves the quality of sewage treatment. At the same time, the sludge is compressed by the extrusion component 8 to reduce its water content, thereby increasing the treatment depth of the entire sewage treatment system for sludge and water, making the treated products more in line with environmental protection and subsequent treatment requirements.

[0036] Example 2 is based on Example 1, and aims to achieve a comprehensive treatment of the water surface from two aspects: aeration and oxygenation, and impurity collection.

[0037] SeeFigures 1-9 The outer shell 1 includes a feed inlet 11, and the lower end of the outer shell 1 is fixedly connected with a base 12, the left side of the lower end of the outer shell 1 is provided with a water outlet one 13, the right side of the lower end of the outer shell 1 is provided with a discharge outlet one 14, and the inside of the outer shell 1 is fixedly connected with a partition plate 15.

[0038] Specifically, the partition plate 15 in the above can separate the separated mud and water.

[0039] Referring to Figure 3 The separation assembly 2 includes a support seat one 21 fixedly connected with the left side of the outer shell 1, the outer surface of the support seat one 21 is provided with a through slot 211, the upper end of the support seat one 21 is fixedly installed with a motor 22, the output end of the motor 22 is fixedly connected with a horizontal screw centrifuge 23, the right side of the lower end of the horizontal screw centrifuge 23 is provided with a water outlet two 24, and the left side of the lower end of the horizontal screw centrifuge 23 is provided with a discharge outlet two 25.

[0040] Further, the through slot 211 is convenient for the belt pulley transmission group one 31 to pass through, the horizontal screw centrifuge 23 in the above is a conventional technical means in the prior art, and the specific working principle is that:

[0041] The horizontal screw centrifuge 23 is mainly composed of a rotating drum and a screw conveyor. When the device is started, the rotating drum rotates at high speed, and a strong centrifugal force field is formed inside. The centrifugal force can be hundreds or even thousands of times greater than gravity. After the mud-water mixture enters the rotating drum from the feed inlet 11, different centrifugal sedimentation speeds are generated due to the different densities of mud solid particles and water under the action of the centrifugal force. The mud particles with high density are thrown to the inner wall of the rotating drum under the action of the centrifugal force and gradually settle to form a mud layer on the inner wall of the rotating drum; and the water with relatively small density forms an inner water ring inside the mud layer.

[0042] The screw conveyor rotates in the same direction as the rotating drum but has a different rotating speed, scrapes the mud on the inner wall of the rotating drum, and conveys the mud to the water outlet two 24 at the small end of the rotating drum for discharge. The water in the inner water ring flows out through the discharge outlet two 25 at the large end of the rotating drum, so that the separation of mud and water is realized.

[0043] Further, the motor 22 and the horizontal screw centrifuge 23 pour the mud-water from the feed inlet 11, the mud-water enters the horizontal screw centrifuge 23 for separation, the separated mud is discharged from the water outlet two 24, and the water is discharged from the discharge outlet two 25.

[0044] Referring to Figure 4 and Figure 5, the connecting assembly 3 comprises a belt pulley transmission set one 31 fixedly connected with the output end of the motor 22, the outer surface of the belt pulley transmission set one 31 is in sliding connection with the through groove 211, one end of the belt pulley transmission set one 31 away from the output end of the motor 22 is fixedly connected with a rotating shaft one 32, the right end of the rotating shaft one 32 is in rotational connection with the outer shell body 1, the outer surface of the rotating shaft one 32 is fixedly connected with a bevel gear transmission set 33, one end of the bevel gear transmission set 33 away from the rotating shaft one 32 is in rotational connection with a connecting plate 34, the right end of the connecting plate 34 is fixedly connected with the outer shell body 1.

[0045] The belt pulley transmission set one 31 in the above is composed of two belt pulleys with different diameters and a belt, wherein the belt pulley connected with the rotating shaft one 32 has a larger diameter, so that the rotating speed of the rotating shaft one 32 is slower, and the bevel gear transmission set 33 in the above is composed of two bevel gears meshing with each other, which changes the rotating direction.

[0046] The belt pulley transmission set one 31 is driven by the output end of the motor 22 to rotate together, and the belt pulley transmission set one 31 drives the rotating shaft one 32 to rotate when rotating, thereby driving the bevel gear transmission set 33 to rotate.

[0047] Referring to Figure 5 and Figure 6 , the swing pushing assembly 4 comprises a connecting rod one 411 fixedly connected with the rear end of the bevel gear transmission set 33, one end of the connecting rod one 411 away from the bevel gear transmission set 33 is in rotational connection with a connecting rod two 41, the outer surface of the connecting rod one 411 is in rotational connection with the connecting plate 34, one end of the connecting rod two 41 away from the connecting rod one 411 is in rotational connection with a sector tooth 42, one end of the sector tooth 42 away from the connecting rod two 41 is fixedly connected with a rotating shaft two 43, the outer surface of the rotating shaft two 43 is in rotational connection with an L-shaped support frame 44, and the upper end of the L-shaped support frame 44 is fixedly connected with the lower end of the support seat one 21.

[0048] Further, the bevel gear transmission set 33 drives the connecting rod one 411 to rotate continuously, and the connecting rod one 411 drives the connecting rod two 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 that the connecting rod two 41 can push the sector tooth 42 to reciprocating swing with the rotating shaft two 43 as the axis during movement.

[0049] The connecting rod one 411 rotates with the bevel gear transmission set 33, and drives the connecting rod two 41 to swing during the rotating process, and because the other end of the connecting rod two 41 is connected with the sector tooth 42, the connecting rod two 41 can only perform reciprocating pushing and pulling action, thereby pulling the sector tooth 42 to reciprocating swing with the rotating shaft two 43 as the axis.

[0050] The lower end of the L-shaped support frame 44 is rotationally connected with a fixed shaft 46 near one side of the outer shell 1, the outer surface of the fixed shaft 46 is fixedly connected with a gear one 45, the front side of the gear one 45 is fixedly connected with a gear two 47, the outer surface of the sector tooth 42 is meshingly connected with the gear one 45, the lower end of the L-shaped support frame 44 is slidingly connected with a T-shaped limiting seat 48, the lower end of the T-shaped limiting seat 48 is fixedly connected with a rack 49, the outer surface of the rack 49 is meshingly connected with the gear two 47, the rack 49 is fixedly connected with a push rod 410 near one side of the outer shell 1.

[0051] The sector tooth 42 in the above can be engaged with the gear one 45 when reciprocating, so as to make the gear one 45 reciprocate, and the gear one 45 will drive the fixed shaft 46 and the gear two 47 to rotate synchronously, so that the gear two 47 is engaged with the rack 49 and drives the rack 49 to move left and right, wherein the T-shaped limiting seat 48 can limit the rack 49, so that the rack 49 stably slides at the lower end of the L-shaped support frame 44.

[0052] The rack 49 will drive the push rod 410 to move together during the left and right movement.

[0053] Referring to Figure 8 and Figure 9 , the aeration assembly 5 includes a moving plate 51 fixedly connected with the right end of the push rod 410, the left side of the partition plate 15 is fixedly connected with a fixed plate 52, the outer surface of the fixed plate 52 is provided with a sliding groove 521, the outer surface of the moving plate 51 is slidingly connected with the sliding groove 521, the left end of the partition plate 15 and the upper side of the fixed plate 52 are fixedly connected with an air bag 53, and the left end of the air bag 53 is fixedly connected with the moving plate 51.

[0054] The lower side of the left end of the moving plate 51 is provided with a plurality of one-way valves 54, the inner surface of the moving plate 51 is provided with an air pipe, the air pipe is fixedly connected with the left end of the air bag 53 through the moving plate 51, and the rear end of the air bag 53 is provided with an air outlet valve and extends to the outer surface of the outer shell 1.

[0055] The moving plate 51 in the above will be driven by the push rod 410 to move left and right, and during the movement, the moving plate 51 will extrude the air bag 53 to become smaller, so that the air in the air bag 53 is discharged from the one-way valve 54 through the air pipe in the moving plate 51, and the moving plate 51 will also drive the one-way valve 54 to move synchronously, so as to increase the dissolved oxygen content in the water from different positions of the water, and the released air will form bubbles in the water, which can absorb and wrap suspended impurities in the sewage during the rising process in the water, so that these impurities float to the water surface together with the bubbles;

[0056] The air outlet valve extends to the outer surface of the outer shell 1. When the push rod 410 drives the moving plate 51 to move to the left side, the air bag 53 is pulled to be larger, the air pressure in the air bag 53 is smaller, the external atmospheric pressure pushes the air into the air bag 53, the fresh air outside is absorbed from the air outlet valve, the air bag 53 is replenished with air in time, the next aeration and oxygenation is prepared, and the continuity and stability of the aeration process are ensured.

[0057] Referring to Figure 4 and Figure 7 The adsorption assembly 6 comprises a support seat two 61 fixedly connected with the lower end of the support seat one 21, a water bag 62 fixedly connected with the lower end of the support seat two 61, an oscillating plate 63 fixedly connected with the outer surface of the front end of the rotating shaft two 43, the upper end of the oscillating plate 63 is fixedly connected with the water bag 62, a water suction pipe 64 fixedly connected with the right end of the water bag 62, a limiting block 65 fixedly connected with the outer surface of the lower end of the water suction pipe 64, and a floating ball 66 fixedly connected with the rear end of the limiting block 65.

[0058] Further, the oscillating plate 63 in the above-mentioned synchronously oscillates with the rotating shaft two 43, and the water bag 62 changes its own air pressure following the oscillation of the oscillating plate 63, so as to perform water suction and drainage movements. The left end of the water bag 62 is provided with a one-way valve, which can discharge the sewage adsorbed in the water bag 62 to the external sewage collecting tank.

[0059] The floating ball 66 in the above-mentioned can automatically adjust the position according to the fluctuation of the water surface, so as to ensure that the water inlet of the water suction pipe 64 connected therewith is always at the highest position of the water surface, thereby facilitating the suction of impurities floating on the water surface through the aeration assembly 5.

[0060] Further, when the fan-shaped teeth 42 oscillate upward, the gear one 45 rotates counterclockwise, the fixed shaft 46 and the gear two 47 rotate in the same direction, thereby driving the rack 49 and the push rod 410 to move to the right side, and extruding the moving plate 51 and the air bag 53, so that the one-way valve 54 injects fresh air into the water. Simultaneously, when the fan-shaped teeth 42 oscillate upward, the rotating shaft two 43 and the oscillating plate 63 synchronously oscillate upward, at this time, the oscillating plate 63 extrudes the water bag 62, so that the water bag 62 becomes smaller, and the wastewater in the water bag 62 is discharged from the one-way valve at the left end. When the fan-shaped teeth 42 oscillate downward, the air bag 53 is absorbing fresh air from the outside, at this time, the oscillating plate 63 pulls the water bag 62 downward, so that the water bag 62 becomes larger, the air pressure in the water bag 62 changes, and the water bag 62 absorbs the water at the uppermost end in the outer shell 1 through the water suction pipe 64, and the impurities floating on the water surface are sucked.

[0061] Referring to Figure 9 The extrusion assembly 8 comprises a sliding rod 81 fixedly connected with the upper end of the moving plate 51, and an extrusion plate 82 fixedly connected with the lower end of the sliding rod 81.

[0062] The sliding rod 81 and the extrusion plate 82 move with the moving plate 51, and simultaneously extrude and dewater the sludge, thereby reducing the water content of the sludge, wherein a separate drain valve is arranged at the rear side of the outer shell 1.

[0063] Therefore, the air bag 53 in the aeration assembly 5 reciprocates by the cooperation between the separation assembly 2, the connecting assembly 3 and the pushing assembly 4, fresh air is released into the separated water, the dissolved oxygen content in the water is increased, which helps to decompose and metabolize the organic matter in the sewage, and through the cooperation of the aeration assembly 5 and the adsorption assembly 6, the impurities float up while the aeration assembly 5, and the synergistic effect of the swing plate 63, the water bag 62 and the float ball 66 can timely absorb the impurities on the water surface, which comprehensively treats the water surface from the aspects of aeration and oxygenation and impurity collection, greatly improves the effect of surface treatment of the sewage, ensures the cleanliness of the water surface and the improvement of the water quality, and simultaneously drives the extrusion assembly 8 to extrude the separated sludge, thereby improving the overall working efficiency.

[0064] In example three, the effect of preventing the feeding port 11 from being blocked is achieved on the basis of examples one and two.

[0066] Specifically, the belt wheel transmission group two 72 is composed of two belt wheels with different diameters and a belt, wherein the belt wheel connected with the rotating shaft three 71 rotates at a slower speed, and the belt wheel transmission group two 72 is driven to rotate by the output end of the motor 22, wherein the rotating shaft three 71 can provide support for the belt wheel transmission group two 72, and when the rotating shaft three 71 rotates, the bevel gear one 73 and the bevel gear two 74 are meshed, thereby driving the scraper 75 to continuously rotate along the inner surface of the feeding port 11, and timely scraping off the sludge adhered to the feeding port, effectively preventing the feeding port from being blocked due to the accumulation of sludge, and ensuring that the sewage can continuously and smoothly enter the horizontal screw centrifuge 23 for separation treatment.

[0067] Therefore, the present application can timely scrape the mud and water adhered to the inner surface of the feed inlet 11 by continuously rotating the scraper 75 in the feed inlet 11, effectively prevent the feed inlet 11 from being blocked due to the accumulation of mud and water, ensure that the sewage can continuously and smoothly enter the horizontal screw centrifuge 23 for separation and treatment, guarantee the continuity of the entire sewage treatment process, and reduce the additional pressure and wear caused by poor feeding on the horizontal screw centrifuge 23, which is helpful to prolong the service life of the horizontal screw centrifuge 23 and reduce the equipment maintenance cost.
