Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a high-efficiency sludge stabilization treatment device. Background Technology
[0002] In today's field of environmental protection and sustainable resource utilization, sludge treatment has become a critical issue. With industrial development and accelerated urbanization, the volume of wastewater treated is constantly increasing, and the resulting large amounts of sludge are putting enormous pressure on the environment.
[0003] Traditional sludge treatment methods lack efficient pre-treatment devices for sludge stabilization, resulting in a continuous influx of sludge into aeration tanks. This leads to excessive sludge settling at the bottom of aeration and sedimentation tanks, hindering the achievement of ideal stabilization. Currently, many sludge treatment methods simply involve stockpiling or landfilling, which not only occupies significant land resources but may also cause secondary pollution to soil and groundwater.
[0004] Furthermore, existing sludge treatment technologies often fail to achieve effective sludge separation. Sludge contains a large amount of water, and if this water cannot be effectively separated, it increases the difficulty and cost of subsequent treatment. Therefore, we designed a device that first filters the sludge, then uses aeration and sedimentation to achieve filtration and discharge, effectively reducing sludge sedimentation in the aeration tank. Utility Model Content
[0005] In view of the technical problems existing in the background art, this utility model provides a high-efficiency sludge stabilization treatment device to solve the problem that in the existing equipment, most of the sludge tends to enter the sedimentation tank and aeration tank during sludge treatment, resulting in a large amount of sedimentation inside the tank and cumbersome cleaning.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0027] like Figures 1-6As shown, a high-efficiency sludge stabilization treatment device includes a tank 1, a conveyor belt 4, and a feeding mechanism 3. The tank 1 is a rectangular cavity structure with an open top, and the tank 1 is provided with a first chamber A, a second chamber B, a third chamber C, a fourth chamber D, a fifth chamber E, and a sixth chamber F. The first chamber A is provided with a conveyor belt 4, and the feeding mechanism 3 is provided on the upper part of the conveyor belt 4. The feeding mechanism 3 includes a support plate 301, a support rod 302, a feed hopper 303, a feed box 304, and a screen 307. The feed box 304 is provided on the upper part of the support plate 301, and the feed... The inside of the box 304 is provided with a screen 307, and the screen 307 and the inner cavity of the feeding box 304 form a cavity structure. The side of the feeding box 304 is provided with a first discharge port 306. The upper part of the feeding box 304 is provided with a feeding hopper 303, and the bottom of the feeding hopper 303 is connected to the side wall of the trough 1 through a support rod 302. The screen 307 is a conical cavity structure with openings at both the top and bottom. The side of the screen 307 is provided with several screening holes 308. The lower part of the screen 307 is provided with a discharge port 309, which is connected to the discharge trough at the bottom of the feeding box 304.
[0028] It should be noted that if sludge is directly introduced into the treatment tank during sludge treatment, it will cause large-scale sludge sedimentation inside the aeration tank and sedimentation tank, making sludge cleaning difficult. Based on this, we designed a device that can filter the sludge to be purified in advance, thereby reducing the sedimentation inside the tank and reducing the need for subsequent cleaning.
[0029] It should be further explained that the first chamber A of the tank 1 is equipped with a conveyor belt 4, which is used to receive the sludge that falls down after screening by the upper feeding mechanism 3, so as to realize automated transportation. The feeding mechanism 3 at the top of the conveyor belt 4 can perform the first screening of the sludge. The sludge enters the feeding box 304 through the feeding trough 303 and is then screened by the screen mesh 307. The screen mesh 307 is a cylindrical cavity structure with open ends. The screen mesh 307 and the feeding box 304 form a cavity. The water stains of the sludge are screened out through the screening holes 308 on the side wall of the screen mesh 307. The screened sludge enters the conveyor belt 4 through the discharge port 309 at the bottom to realize the transfer.
[0030] It should be further explained that after the sludge is screened, it enters the feed box 304 and then enters the second chamber B through the water inlet pipe 305, thus realizing the simultaneous screening and material guiding.
[0031] like Figure 1 , Figure 3 and Figure 4 An aeration device 2 is provided on the side of the tank 1 shown, and the aeration device 2 extends into the first chamber A and the second chamber B through the air guide pipe 12.
[0032] It should be noted that proper aeration can promote the flocculation of fine particles in wastewater. During aeration, the agitation of the water flow and the dispersion of the gas cause colloidal particles and tiny suspended solids in the wastewater to collide with each other. As the number of collisions increases, these particles may combine to form larger flocs.
[0033] like Figures 1-6 As shown, the fourth chamber D is equipped with a feeding mechanism 6. The feeding mechanism 6 includes a sliding bar 601, a screw 602, a feeding trough 603 and a first drive motor 604. The feeding trough 603 is connected to the sliding bar 601 and the screw 602 through the bottom groove and the screw hole, respectively. One end of the screw 602 is connected to the output shaft of the first drive motor 604 through a coupling.
[0034] It should be noted that the feeding mechanism 6 is designed to add flocculant. In order to add flocculant evenly into the fourth chamber D, the feed chute 603 is connected to the sliding bar 601 and the screw 602 through the bottom groove and screw hole, respectively. It is driven by the first drive motor 604 to achieve reciprocating drive. The screw 602 can be replaced by a bidirectional screw. In this way, the flocculant is added reciprocally.
[0035] like Figures 1-6 As shown, the fifth chamber E and the sixth chamber F are located on one side of the fourth chamber D. A water pump 8 and a water pipe 7 are provided at one end of the fifth chamber E. A drain outlet 11 is provided on one side of the sixth chamber F. The drive roller of the conveyor belt 4 is connected to the second drive motor through a connector. The conveyor belt 4 is a stainless steel track belt with several screen holes. A feeder 10 is provided at one end of the first chamber A, and a scraper 9 is provided inside the feeder 10. The first discharge port 306 is connected to the second chamber B through a water inlet pipe 305. The bottom of the first chamber A is connected to the second chamber B.
[0036] It should be noted that the fifth chamber E is a flocculation tank, which treats the wastewater after the addition of flocculant. Through settling and sedimentation, the flocculants in the wastewater are discharged through the water pump 8 and the water pipe 7, while the relatively clean water in the upper part enters the sixth chamber F and is discharged through the drain outlet 11.
[0037] It should be further explained that when the conveyor belt 4 is transporting sludge, the sludge will adhere to its upper part. If it is not removed, it will affect subsequent work. Therefore, we designed a scraper 9, which is closely attached to the surface of the conveyor belt 4 to remove the sludge during the transportation process.
[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
