Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a sludge resource crushing, drying, and utilization device. Background Technology

[0002] Sludge drying treatment refers to reducing the water content of sludge through physical, chemical, or biological means, so as to achieve sludge reduction, stabilization, harmlessness, and resource utilization, thereby reducing sludge volume and reducing the cost and environmental impact of subsequent treatment (such as landfill and incineration).

[0003] Chinese Patent Publication No. CN222665674U discloses a dewatering and drying device for sludge treatment, including a drying bed. A conveyor belt is movably installed on the drying bed, and a transfer belt is installed on the bottom right side of the conveyor belt. A drying frame is fixedly installed on the drying bed, and a drive motor is screwed to the surface of the drying frame. The output shaft of the drive motor is fixed to the shaft of a rotating wheel, and the shaft of the rotating wheel is movably connected to a transmission arm. In this dewatering and drying device for sludge treatment, high-temperature hot air enters from the hot air pipe into the interior of three sets of air inlet pipes and enters the interior of the drying frame in three groups. At the same time, the external switch of the drive motor is activated, and the drive plate, transmission arm, rotating wheel, and drive motor drive the sludge to reciprocate laterally. This causes seven sets of sludge-turning feet to turn the sludge, allowing hot air to contact both the inside and outside of the sludge, thus achieving thorough and uniform drying and dewatering of the sludge.

[0004] In the aforementioned prior art, the sludge can be turned over by the set sludge turning feet, and the sludge can be dried by high temperature hot air. However, the sludge is prone to caking during storage, transportation or treatment. The moisture inside the caking sludge is difficult to evaporate, which requires increasing the temperature of the drying equipment, extending the drying time or increasing the ventilation volume, resulting in increased drying energy consumption.

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] Example 1:

[0057] like Figures 1 to 6 As shown, this utility model provides a sludge resource crushing, drying and utilization device, including a processing box 1 arranged inside the processing box 1 for screening out clumps in the sludge.

[0058] The screening structure includes a conical screening cylinder 2 rotatably installed inside the processing box 1, a connecting bracket 201 arranged on the inner wall of the conical screening cylinder 2 and rotatably installed inside the processing box 1, a geared motor 202 arranged on one side of the processing box 1, the output end of the geared motor 202 arranged on the connecting bracket 201, a receiving hopper 203 arranged on the processing box 1 and connected to the processing box 1, and a guide chute 204 opened inside the processing box 1. The conical screening cylinder 2 is located in the guide chute 204. Sludge is continuously added to the receiving hopper 203, and the sludge will fall into the guide chute 204 and be located on the surface of the conical screening cylinder 2. At the same time, the geared motor 202 can be turned on to drive the conical screening cylinder 2 to rotate, which helps to separate the clumps in the sludge.

[0059] Example 2:

[0060] Based on Example 1, in order to remove water from the sludge, a dewatering structure for separating water from the sludge is arranged inside the treatment box 1. The dewatering structure includes a crushing component for crushing sludge clumps and a squeezing component for squeezing the sludge to dewater it.

[0061] The crushing assembly includes two linkage rollers 3 and two linkage shafts 303 rotatably installed inside the processing box 1, several crushing plates 301 evenly arranged on the two linkage rollers 3, two linkage gears 302 respectively arranged at one end of the two linkage rollers 3, the two linkage gears 302 meshing with each other, a second reduction motor 304 arranged on one side of the processing box 1, the output end of the second reduction motor 304 arranged on the corresponding linkage shaft 303, four transmission wheels 305 respectively arranged on the two linkage shafts 303 and the two linkage gears 302, and two transmission belts 306 symmetrically installed on the four transmission wheels 305. By turning on the second reduction motor 304, the linkage shafts 303 can be driven to rotate, so that through the cooperation of the transmission wheels 305, transmission belts 306 and the two linkage gears 302, the two linkage shafts 303 can be driven to rotate simultaneously in a direction closer to each other. The sludge clumps screened out by the conical screening cylinder 2 can slide along the inclined surface of the conical screening cylinder 2 towards the crushing plates 301, so that the circularly moving crushing plates 301 can crush the sludge clumps.

[0062] The crushing assembly also includes a guide chute 307 located inside the processing chamber 1 and corresponding to the conical screening cylinder 2, a discharge port 308 located inside the processing chamber 1, and a guide support 310 arranged inside the discharge port 308. The crushed sludge will slide down from the inclined surface of the guide chute 307 into the conical screening cylinder 2, where the crushed sludge can be screened a second time. The sludge that is not completely crushed will slide out from the discharge port 308 and the guide support 310.

[0063] The extrusion assembly includes two extrusion rollers 309 that are respectively fixedly sleeved on two linkage shafts 303. When the linkage shafts 303 rotate, they can rotate simultaneously in a direction that moves closer to each other, thereby driving the two extrusion rollers 309 to rotate synchronously and extrude and dewater the sludge.

[0064] Example 3:

[0065] Based on Example 1, in order to further improve the dewatering effect of sludge, a conveying and filtering structure for conveying dewatered sludge is arranged inside the treatment tank 1.

[0066] The conveying and filtering structure includes an arc-shaped receiving plate 4 arranged inside the processing box 1, a number of holes 401 evenly opened inside the arc-shaped receiving plate 4, and a water tank 402 opened inside the processing box 1. The water that is removed can flow through the holes 401 on the arc-shaped receiving plate 4 to the water tank 402 and be discharged.

[0067] The conveying and filtering structure also includes a mounting shaft 403 rotatably installed inside the processing box 1, a spiral feeding blade 404 fixedly sleeved on the mounting shaft 403 and in contact with the inner wall of the arc-shaped receiving plate 4, a geared motor 405 arranged on one side of the processing box 1, the output end of the geared motor 405 being arranged on the mounting shaft 403, and a drying component arranged on the arc-shaped receiving plate 4 to assist in drying and dewatering the sludge. Turning on the geared motor 405 can drive the mounting shaft 403 to rotate, which in turn drives the spiral feeding blade 404 to rotate. The rotating spiral feeding blade 404 can move the sludge, which is eventually discharged from the arc-shaped receiving plate 4.

[0068] Specifically, the drying assembly includes a guide hood 406 arranged below the arc-shaped receiving plate 4, and a hot air blower 407 arranged on one side of the guide hood 406. The blowing end of the hot air blower 407 is located inside the guide hood 406. When the hot air blower 407 is turned on, hot air can be blown. The hot air can contact the dewatered sludge through the leakage hole 401 at one end of the arc-shaped receiving plate 4 for drying.

[0069] Working principle: During operation, sludge is continuously added to the receiving hopper 203. The sludge falls into the guide chute 204 and is located on the surface of the conical screening cylinder 2. Simultaneously, the geared motor 202 can be turned on to drive the connecting bracket 201 to rotate, which in turn drives the conical screening cylinder 2 to rotate. The rotation of the conical screening cylinder 2 promotes the movement of sludge on its surface, which helps to separate clumps in the sludge. Sludge of suitable size flows downward through the mesh of the conical screening cylinder 2 into the interior of the conical screening cylinder 2 for secondary screening, and finally falls between the two extrusion rollers 309. Turning on the geared motor 304 drives the linkage shaft 303 to rotate. The linkage shaft 303 drives the linkage gear 302 to rotate through the transmission wheel 305 and the transmission belt 306. Through the meshing of the two linkage gears 302 and another set of transmission wheels 305, The transmission belt 306, in conjunction with the transmission belt 306, enables the two linkage shafts 303 to rotate simultaneously in a direction closer to each other, thereby driving the two extrusion rollers 309 to rotate synchronously, extruding and dewatering the sludge. The dewatered water can flow through the holes 401 on the arc-shaped receiving plate 4 to the water tank 402 and be discharged. The dewatered sludge is received by the arc-shaped receiving plate 4. At this time, the geared motor 3 405 is turned on, which drives the mounting shaft 403 to rotate, causing the mounting shaft 403 to drive the spiral feed plate 404 to rotate. The rotating spiral feed plate 404 can drive the sludge to move, and finally it is discharged from the arc-shaped receiving plate 4. At the same time as the sludge is discharged, the hot air fan 407 can be turned on, which can blow hot air, so that the hot air enters the arc-shaped receiving plate 4 through the holes 401 at one end of the arc-shaped receiving plate 4, and comes into contact with the dewatered sludge to dry it.

[0070] The sludge clumps screened out by the conical screening cylinder 2 can slide along the inclined surface of the conical screening cylinder 2 toward the crushing plate 301. Under the continuous rotation of the linkage roller 3, the crushing plate 301 can move in a circular motion and crush the sludge clumps. The crushed sludge will fall into the guide chute 307, and then slide down the inclined surface of the guide chute 307 into the interior of the conical screening cylinder 2. Under the continuous rotation of the conical screening cylinder 2, the crushed sludge can be screened a second time. Sludge of suitable size will continue to fall through the mesh on the conical screening cylinder 2, while the sludge that is not completely crushed will slide out from the discharge port 308 and the guide tray 310. A material frame can be set below the guide tray 310 to collect it for secondary processing.

[0071] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
