Description

Technical Field

[0001] This invention belongs to the technical field of sludge treatment equipment, specifically a vertical sludge thickening and processing device. Background Technology

[0002] In sludge treatment processes, centrifugal thickening and pressure filtration dewatering are the core treatment steps to achieve sludge reduction. Centrifugal thickening relies on centrifugal force to accelerate the sedimentation of particles in sludge, achieving preliminary solid-liquid separation and reducing sludge moisture content and volume.

[0003] In centrifugal thickening equipment, cage-type vertical centrifugal thickeners are widely used in small sludge treatment plants and other places due to their advantages such as high efficiency, compactness, and low speed. Their main advantages are that they do not require chemical addition, have a small footprint, and are safe and hygienic to operate. The core principle of the cage-type vertical centrifugal thickener is the dual action of centrifugal force and filtration. It mainly utilizes the density difference and inertia difference between solid particles and liquid (water) in sludge. When the sludge rotates at high speed in the centrifuge, the centrifugal force on the denser solid particles is much greater than the gravity (usually hundreds to thousands of times the gravity), so they are thrown against the cylinder wall or trapped on the filter medium, while the liquid passes through the filter cloth and is discharged, realizing solid-liquid separation and sludge thickening.

[0004] However, in practical applications, it has been found that since the cage-type vertical centrifugal thickener is mainly positioned for thickening, the purpose is to change the sludge from a pumpable dilute state to a still pumpable concentrated state. Therefore, during operation, it is highly dependent on the fluidity of the sludge. When the transported sludge is too viscous or the sludge moisture content changes significantly, the thickening effect can be greatly affected.

[0005] In view of this, the present invention proposes a vertical sludge thickening and processing device to solve the above-mentioned technical problems. Summary of the Invention

[0012] Preferably, each of the closed loops is composed of a spring sheet, a flexible sheet, and a multi-head telescopic rod; The multi-head telescopic rod is fixedly installed at the end of the controllable telescopic rod. A spring plate is fixedly installed at the end of the multi-head telescopic rod away from the controllable telescopic rod. The cross-section of the spring plate is initially arc-shaped. The flexible plate is fixedly installed on the spring plate.

[0013] Preferably, it also includes an airflow assist mechanism, which is used to assist the sludge in moving on the filter drum.

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 8 As shown, the vertical sludge thickening and processing device of the present invention includes a thickening shell 1, a filter drum 2, a drive motor 21 and a feed pipe 14. The concentration shell 1 is a hollow structure, and the filter drum 2 is rotatably installed inside the concentration shell 1. The filter drum 2 divides the inner cavity of the concentration shell 1 into a centrifugation chamber 11, a concentration chamber 12, and a filtrate chamber 13. The drive motor 21 is fixedly installed at the bottom of the concentration shell 1, and the drive motor 21 is connected to the filter drum 2; The feed pipe 14 is fixedly installed on the concentration shell 1, and the feed pipe 14 extends to the center of the inner cavity of the filter drum 2; It also includes a sensing adjustment mechanism, which is installed inside the concentration housing 1. The sensing adjustment mechanism adjusts the filtration height by sensing the weight of the filter drum 2. The sensing adjustment mechanism includes a connecting pipe 22, a weight sensor, a mounting frame 24, and a closed loop; A connecting pipe 22 is fixedly installed at the bottom of the filter drum 2. The output end of the drive motor 21 extends into the connecting pipe 22, and the output end of the drive motor 21 is axially slidably connected to the connecting pipe 22 and circumferentially engaged. A support platform 23 is fixedly installed at the output end of the drive motor 21, and a weight sensor is installed between the support platform 23 and the connecting pipe 22. The mounting frame 24 is mounted on the filter drum 2. The mounting frame 24 is a frame-type structure. Controllable telescopic rods 25 that are evenly distributed are fixedly mounted on the mounting frame 24. The closed ring is fixedly installed on the controllable telescopic rod 25. The closed ring is a ring structure, and the side of the closed ring near the filter drum 2 is made of elastic sealing material.

[0023] In the sludge centrifugal thickening process, the sludge is subjected to centrifugal force in the filter drum 2. As it moves from bottom to top, the moisture content gradually decreases. With the increase of the movement path and the extension of the centrifugation time, the sludge moisture content will gradually decrease. In order to make the sludge thickening effect more stable after centrifugation, the present invention is equipped with a sensing adjustment mechanism. The overall weight change caused by the solid content of the sampled sludge is used to adjust the filtration area of ​​the filter drum 2, thereby adjusting the sludge thickening effect accordingly. When the moisture content of the sampled sludge changes, it plays a role in stabilizing the moisture content of the thickened sludge.

[0024] Specifically, during the centrifugal concentration process, the sludge is transported to the concentration shell 1 through the feed pipe 14, and finally falls to the bottom of the centrifugal chamber 11 formed by the inner cavity of the filter drum 2 under the action of gravity. At this time, the drive motor 21 drives the connecting pipe 22 and the filter drum 2 to rotate centrifugally. Under the action of a stable rotation speed, the sludge in the filter drum 2 is thrown onto the inner wall of the filter drum 2 under the action of centrifugal force, and gradually moves upward along the inner wall of the filter drum 2. During this process, the filter drum 2, which is composed of a cage and filter cloth, continuously filters the sludge. Filtration separation allows the water components in the sludge to enter the filtrate chamber 13 through the pores of the filter drum 2. As the sludge continues to rise, after reaching the top of the filter drum 2, the concentrated sludge enters the thickening chamber 12 from the centrifuge chamber 11. When the moisture content of the feed sludge remains within a small range, the total weight of the filter drum 2 and the sludge inside it remains within a stable range due to the stable feed rate and rotation speed. However, when the moisture content of the feed sludge changes, as the moisture content of the feed sludge decreases... As the density of the sludge increases, the total weight of the same volume of sludge increases. This causes a change in the total weight of the filter drum 2 and the sludge. Under gravity, the weight detected by the weight sensor located between the support platform 23 and the connecting pipe 22 changes significantly. Under the action of the weight sensor, the controllable telescopic rod 25 extends, causing the closed ring to adhere to the outer wall of the filter drum 2. The closed ring blocks the filtration channel of the filter drum 2. Therefore, as the sludge rises along the filter drum 2, its total distance does not change. However, because filtration cannot be performed in some parts of the distance, the total filtration time is shortened, thus reducing the sludge thickening effect. Conversely, when the moisture content of the feed sludge increases, the closed ring disengages from the filter drum 2, thus extending the total filtration time and enhancing the sludge thickening effect. During long-term sludge thickening, especially when the moisture content of the feed sludge changes significantly, it can regulate the thickening effect, thereby reducing the variation in moisture content of the final thickened sludge under the same centrifugal effect.

[0025] This invention, by setting up a sensing adjustment mechanism, detects the total weight of the filter drum 2 and the sludge in real time, and adjusts the filtration time during the sludge movement process based on the detection results, thereby regulating the filtration effect of the water components in the sludge. When the feed sludge concentration is high, the filtration time is shortened; when the feed sludge concentration is low, the filtration time is extended. Therefore, the concentration range of the output concentrated sludge is reduced, and the stability of the concentrated sludge output is enhanced.

[0026] It is important to know that sludge thickening is to change sludge from a pumpable dilute state to a still pumpable concentrated state. Therefore, when the output concentrated sludge concentration is too high, it will reduce its fluidity and be detrimental to subsequent transportation. On the other hand, when the output concentrated sludge concentration is too low, the thickening effect will not be ideal. Therefore, it is necessary to enhance the stability of the output concentrated sludge.

[0027] In a preferred embodiment of the present invention, the weight sensing element includes a hydraulic telescopic cylinder 3, a support spring 31, and a series tube 26; The hydraulic telescopic cylinder 3 is fixedly installed at the bottom of the connecting pipe 22, and the hydraulic telescopic cylinder 3 is connected to the controllable telescopic rod 25 through the series pipe 26. The support spring 31 is fixedly installed inside the hydraulic telescopic cylinder 3.

[0028] An electromagnetic adjusting cylinder 32 is fixedly installed on the hydraulic telescopic cylinder 3. The electromagnetic adjusting cylinder 32 is electrically connected to the hydraulic telescopic cylinder 3 and is used to control the initial height of the controllable telescopic rod 25.

[0029] In this invention, the hydraulic telescopic cylinder 3 is located between the connecting pipe 22 and the support platform 23. When the filter drum 2 maintains a stable rotation speed, the support spring 31 is used to overcome the total weight of the filter drum 2 and its upper structure. At this time, under the control of a pre-set program, the electromagnetic regulating cylinder 32 adjusts its total length according to the rotation speed of the filter drum 2, thereby making the controllable telescopic rod 25 at a pre-set height. When sludge begins to be fed, as the sludge gradually enters the filter drum 2, the weight sensor is gradually compressed. Under the conduction of the series pipe 26, the hydraulic oil in the hydraulic telescopic cylinder 3 enters the controllable telescopic rod 25, causing the closed loop to gradually rise. When the concentration of the fed sludge does not change significantly, the total weight of the filter drum 2 and the sludge inside it quickly reaches a stable value. At this time, according to the change in the degree of compression of the weight sensor before and after the sludge is added, the closed loop partially compresses the filter drum 2. The location is sealed, and when the concentration of the subsequently entering sludge changes significantly, the weight sensor detects and adjusts the sealing area of ​​the closed loop on the filter drum 2 in real time. It should be noted that in this invention, before the equipment is put into use, the staff uses a prepared sludge sample to actively adjust the extension and retraction of the electromagnetic regulating cylinder 32 at different rotation speeds of the filter drum 2, the weight change during the sludge concentration change, and the blocking range of the closed loop on the filter drum 2 during actual experiments. The patterns are summarized and programmed into a pre-set program so that in actual application, the electromagnetic regulating cylinder 32, the hydraulic telescopic cylinder 3, and the controllable telescopic rod 25 work together to adjust the blocking range of the closed loop on the filter drum 2 in real time according to the weight change caused by the sludge concentration change, thereby reducing the concentration range of the final output concentrated sludge and achieving the purpose of stable output of concentrated sludge.

[0030] In a preferred embodiment of the present invention, the controllable telescopic rod 25 and the closed ring are divided into multiple groups, and the multiple groups of controllable telescopic rods 25 are connected in series. The distance between the multiple groups of closed rings and the filter drum 2 gradually decreases from top to bottom.

[0031] When the multiple controllable telescopic rods 25 are fully extended, the multiple closed rings are arranged at equal intervals along the height direction of the filter drum 2.

[0032] Each closed loop is composed of a spring sheet 4, a flexible sheet 41, and a multi-head telescopic rod 42; The multi-head telescopic rod 42 is fixedly installed at the end of the controllable telescopic rod 25. A spring plate 4 is fixedly installed at the end of the multi-head telescopic rod 42 away from the controllable telescopic rod 25. The cross-section of the spring plate 4 is initially arc-shaped. The flexible plate 41 is fixedly installed on the spring plate 4.

[0033] To further enhance the controllability of the closed-loop shielding effect on the filter drum 2, in this invention, when the total weight of the filter drum 2 and the sludge changes, the hydraulic telescopic cylinder 3 and the electromagnetic regulating cylinder 32 work together to cause multiple controllable telescopic rods 25 to extend and retract synchronously, ultimately ensuring that the closed loop is fully attached to the filter drum 2. During this process, as the controllable telescopic rods 25 extend, the spring sheet 4, flexible sheet 41, and multi-head telescopic rod 42 constituting the closed loop first come into contact with the filter drum 2. As the controllable telescopic rods 25 continue to extend, the multi-head telescopic rod 42, under the action of extrusion force, causes the arc-shaped spring sheet 4 to gradually deform and expand. The spring sheet 4 and the flexible sheet 41 unfold and adhere to the filter drum 2. During the unfolding process of the spring sheet 4 and the flexible sheet 41, the blocking area of ​​the closed ring on the filter drum 2 gradually increases. Since multiple closed rings are arranged at equal intervals along the height direction of the filter drum 2, in actual application, multiple closed rings cooperate to achieve flexible adjustment of the blocking area of ​​the filter drum 2. That is to say, when the concentration of the feed sludge reaches the preset concentration of concentrated sludge, the closed ring completely blocks the filter drum 2, while when the concentration of the feed sludge is the initial concentration, the closed ring completely detaches from the filter drum 2.

[0034] This invention adjusts the structure of the closed ring to make the shielding effect of the closed ring on the area of ​​the filter drum 2 more adjustable. Therefore, during the sludge thickening process, it can further enhance the control over the final discharged thickened sludge. In practical applications, it can effectively enhance the intervention effect of the sensing and regulating mechanism on sludge thickening.

[0035] As a preferred embodiment of the present invention, it also includes an airflow assist mechanism, which is used to assist the sludge in moving on the filter drum 2. The airflow assist mechanism includes an air compressor 5, an air supply pipe 51 and an injection pipe 54. The air compressor 5 is installed on the condenser shell 1. The air compressor 5 is used to supply compressed air. The air delivery pipe 51 is fixedly installed at the output end of the air compressor 5. The mounting frame 24 has a rotating groove 52, and a ring plate 53 is rotatably and sealed inside the rotating groove 52. The gas supply pipe 51 is fixedly installed on the ring plate 53 and extends into the rotating groove 52. The spray pipe 54 is fixedly installed on the mounting frame 24, and the spray pipe 54 is electrically connected to the rotating groove 52.

[0036] The flexible sheet 41 has uniformly distributed air jet grooves 43, and the jet pipe 54 extends into the air jet grooves 43.

[0037] The jet grooves 43 are evenly arranged along the circumference of the closed ring, and all jet grooves 43 on a single closed ring are electrically connected.

[0038] The mounting frame 24 is fitted onto the filter drum 2, and an arc-shaped electromagnetic telescopic rod 6 is fixedly installed on the filter drum 2. The mounting frame 24 is fixedly installed on the output end of the electromagnetic telescopic rod 6.

[0039] During sludge thickening, as the concentration of the feed sludge approaches that of the thickened sludge, its fluidity decreases. To enhance the movement of the sludge on the filter drum 2, an airflow assist mechanism is incorporated in this invention. When the closed loop adheres to the filter drum 2, the air compressor 5 is activated according to a pre-set program. The air compressor 5 pumps compressed air to the air delivery pipe 51 and the rotating trough 52, ultimately flowing into the air jet trough 43 through the jet pipe 54. The air jet trough 43 acts on the outside of the filter drum 2, and the airflow impacts the sludge adhering to the inner wall of the filter drum 2 through the pores. This pushing action is opposite to the centrifugal force, thus reducing the difficulty of sludge flow on the filter drum 2 and assisting in sludge flow. Simultaneously, during the airflow impact... During the process, as the airflow passes through the pores of the filter drum 2, it also pushes out the sludge that is blocked in the pores of the filter drum 2, thereby clearing the filter drum 2 and extending the maintenance interval of the filter drum 2. During long-term operation, the electromagnetic telescopic rod 6 is periodically adjusted in length, thereby changing the relative position of the closed ring and the filter drum 2, so that the impact position of the airflow on the filter drum 2 changes, thus achieving a comprehensive cleaning of the filter drum 2. At the same time, during use, the operator can also pre-set the cleaning program, and control the electromagnetic regulating cylinder 32 to retract at certain intervals, so that the closed ring completely seals the filter drum 2. Combined with the continuous extension and retraction of the electromagnetic telescopic rod 6, the filter drum 2 can be cleaned regularly and comprehensively, thereby extending the maintenance interval of the filter drum 2.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
