Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sludge conveying device for water treatment. Background Art

[0002] In modern water treatment systems, treated sludge needs to be efficiently transported to subsequent treatment or disposal facilities to ensure environmental safety and resource utilization efficiency.

[0003] Publication number CN218115246U, a Chinese patent discloses a sludge conveying and drying device for sewage treatment, which includes a drying box, a loading port and a unloading port. A crushing box is fixedly installed on the drying box, and the discharge port of the crushing box is connected to the loading port of the drying box. A breaking mechanism for breaking up agglomerated sludge is provided in the crushing box. The sludge conveying and drying device for sewage treatment can break up agglomerated sludge before loading the sludge, thereby improving drying efficiency and being highly practical.

[0004] Regarding the aforementioned related technologies, this device has some shortcomings. In actual use, the sludge is first broken up inside the breakage box and then enters the drying box through the feed port for drying. However, as the sludge passes through the breakage box, the flow area is relatively large. When the sludge flows through the feed port, the flow area suddenly decreases, which makes it easy for the sludge to clog at the feed port, thus affecting the stable sludge transportation. Therefore, it is necessary to provide a sludge conveying device for water treatment to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a sludge conveying device for water treatment to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] Preferably, a conical platform is fixedly installed on the top of the sealing box.

[0013] Preferably, a guide platform is fixedly installed at the lower part of the crushing box.

[0014] Preferably, a plurality of support rods are fixedly installed between the bottom of the crushing box and the top of the drying box.

When the sludge passes through the feeding pipe, the rotation of the horizontal shaft drives the first bevel gear to rotate. Through the engagement of the first bevel gear and the second bevel gear, the second bevel gear drives the extrusion screw to rotate. The rotation of the extrusion screw orderly and stably outputs the sludge inside the crushing box through the feeding pipe, effectively avoiding the problem of sludge clogging inside the feeding pipe.

[0018] 2. This utility model uses a guide scraper, one side of which slides in contact with the conveyor belt, creating a scraping effect that effectively scrapes the dried sludge directly off the conveyor belt. This design prevents dried sludge from adhering to the conveyor belt, preventing unsmooth sludge discharge and significantly improving the reliability and stability of the device during use.

[0032] An extrusion screw 10 is rotatably installed inside the feeding tube 2, and the top end of the extrusion screw 10 passes through the bottom of the sealing box 16 and extends to the inside of the sealing box 16. The extrusion screw 10 is rotatably connected to the sealed bearing on the inner wall of the sealing box 16. A crushing mechanism is provided above the inside of the crushing box 3. A conduit 5 is fixedly installed and inserted below one side of the outer wall of the feeding tube 2, and the end of the conduit 5 away from the feeding tube 2 passes through the top of the drying box 1 and is connected to the inside of the drying box 1.

[0033] An opening is provided on the other side of the top of the drying box 1 . A guide scraper 7 is fixedly mounted on the drying box 1 through the opening on the other side of the top of the drying box 1 , and one side of the guide scraper 7 is in sliding contact with the conveyor belt 8 .

[0034] In one embodiment, the crushing mechanism includes a horizontal shaft 14, and the horizontal shaft 14 is rotatably installed above the inside of the crushing box 3. The horizontal shaft 14 passes through the sealing box 16 and is rotatably connected to the sealed bearing installed on the inner wall of the sealing box 16. Several cutters 12 are fixedly installed on the outer wall of the horizontal shaft 14. A motor 4 is fixedly installed on one side of the crushing box 3, and the driving end of the motor 4 passes through one side of the crushing box 3 and extends to the inside of the crushing box 3 and is fixedly connected to one end of the horizontal shaft 14. A second bevel gear 18 is fixedly installed on the top of the extrusion screw 10, and a first bevel gear 17 is fixedly installed on the outer wall of the horizontal shaft 14, and the first bevel gear 17 is meshed with the second bevel gear 18, thereby achieving the effect of breaking up the agglomerated sludge, which is beneficial to improving the subsequent drying efficiency of the sludge.

[0035] In one preferred embodiment, a conical platform 13 is fixedly installed on the top of the sealed box 16 to guide the sludge falling on the top of the sealed box 16 and prevent the sludge from remaining on the top of the sealed box 16 .

[0036] In one embodiment, a guide platform 11 is fixedly installed below the inside of the crushing box 3, so that the sludge can be stably transported to the inside of the feeding pipe 2 under the guidance of the guide platform 11, avoiding the formation of sludge residue at the bottom of the crushing box 3.

[0037] In one preferred embodiment, a plurality of support rods 6 are fixedly installed between the bottom of the crushing box 3 and the top of the drying box 1 to improve the stability of the crushing box 3.

[0038] In one embodiment, a tetrafluoroethylene coating is provided on the outer wall of the extrusion screw 10 and the inner wall of the feeding tube 2, which can effectively reduce the adhesion of sludge on the inner surface of the extrusion screw 10 and the feeding tube 2, thereby improving the smoothness of the sludge flow.

[0039] The working principle of the present invention is as follows: the electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing disclosed power connection technology is not described in detail in the text. When in use, the sludge is poured into the crushing box 3 through the top opening. At the same time, the control motor 4 starts to work, and the driving end of the motor 4 drives the horizontal shaft 14 to rotate. The rotation of the horizontal shaft 14 drives the cutter 12 to rotate. The rotation of the cutter 12 will crush the sludge entering the crushing box 3. After being crushed, the sludge flows to the bottom of the crushing box 3 and passes through the feeding pipe 2 and the guide The tube 5 is discharged into the conveyor belt 8 inside the drying box 1. The conveyor belt 8 will continue to transport the discharged sludge, and in the process of transportation, the hot air blower 9 will dry the sludge on the conveyor belt 8. In the process of the sludge passing through the feeding pipe 2, the rotation of the horizontal shaft 14 drives the first bevel gear 17 to rotate. Through the engagement of the first bevel gear 17 and the second bevel gear 18, the second bevel gear 18 drives the extrusion screw 10 to rotate. The rotation of the extrusion screw 10 orderly and stably outputs the sludge inside the crushing box 3 through the feeding pipe 2, effectively avoiding the problem of sludge clogging inside the feeding pipe 2.

[0040] After being transported and dried by conveyor belt 8, the sludge is conveyed to guide scraper 7 and discharged through it. One side of guide scraper 7 slides in contact with conveyor belt 8, creating a scraping effect that effectively scrapes the dried sludge directly off the conveyor belt. This design prevents dried sludge from adhering to conveyor belt 8, preventing problems such as unloading sludge smoothly, thereby significantly improving the reliability and stability of the device during use.
