Description

Technical Field

[0001] The utility model relates to the technical field of sludge transportation, in particular to an automatic feeding device for sludge processing. Background Art

[0002] Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water content from sludge through infiltration or evaporation, generally referring to the use of self-evaporation facilities such as sludge drying fields (beds). After the sludge is concentrated, physical methods are used to further reduce the water content of the sludge to facilitate the transportation, accumulation, utilization or further treatment of the sludge. There are two types of dehydration (drying): natural evaporation and mechanical dehydration. It is customary to call mechanical dehydration sludge dehydration and natural evaporation sludge drying; although the methods are different, they are all measures to further reduce the water content of sludge. After drying, desulfurization and dust removal, the dried sludge needs to be incinerated inside the rotary kiln.

[0003] Traditionally, the sludge is directly transported through a chain conveyor. However, this existing transportation method cannot quantitatively deliver the dried sludge, and the sludge is prone to accumulation on the surface of the conveyor belt, affecting the normal transportation of the sludge.

[0004] A Chinese patent with publication number CN219637070U has been proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: an automatic feeding device for sludge treatment, comprising a workbench, two groups of relatively distributed vertical plates are fixedly installed on the surface of the workbench, the two groups of the vertical plates are commonly fixedly connected to a feeding hopper, the two groups of the vertical plates are commonly rotatably connected to two groups of relatively distributed rotating rods, conveying rollers are respectively fixedly installed on the surfaces of the rotating rods, the two groups of the conveying rollers are commonly connected to a conveyor belt, one end of one group of the rotating rods extends out of the vertical plate and is connected to a motor, an intermittent feeding mechanism is arranged at the bottom end of the feeding hopper, the intermittent feeding mechanism comprises a sealing plate and a control assembly, the sealing plate is rotatably connected to the inner side wall of the feeding hopper, a spreading mechanism located above the workbench is arranged between the two groups of the vertical plates, the spreading mechanism comprises a cleaning assembly and a driving assembly, the cleaning assembly is located above the conveyor belt and is connected to the driving assembly.

[0005] Although the prior art can accurately control the feeding speed and spread and clean the sludge raw materials on the surface of the conveyor belt, the dried sludge particles are of different sizes. When feeding in the feeding hopper, it is easy to clog the bottom feeding port, affecting the feeding effect and the overall conveying efficiency. Utility Model Content

[0028] The present invention is further described in detail below in conjunction with the embodiments:

[0029] Example 1

[0030] like Figure 1-5 As shown, the utility model provides an automatic feeding device for sludge treatment, including a lower hopper 1, a conveyor belt 2, an anti-blocking dredging component 3 and a crushing device 4. The anti-blocking dredging component 3 is used to dredge the lower opening of the lower hopper 1. The anti-blocking dredging component 3 includes a first reciprocating tooth rack 10 and a second reciprocating tooth rack 18 located at the front and rear sides of the lower opening of the lower hopper 1, and a sector gear 11 meshed with the inner walls of the first reciprocating tooth rack 10 and the second reciprocating tooth rack 18. Both ends of the first reciprocating tooth rack 10 are fixedly connected with a conveying plug rod 12 through a plate frame. The conveying plug rods 12 on both sides of the lower opening of the lower hopper 1 are in an alternate insertion state, so that the two sides of the dried sludge in the blocked area are alternately impacted, thereby improving the dredging efficiency.

[0031] The guide plate frames 15 installed on the upper and lower sides of the first reciprocating tooth rack 10 guide and limit it so that it can move in parallel to ensure the stability of subsequent operation.

[0032] A docking hole is provided on the outer wall of the discharge port of the discharge hopper 1 , and the inner wall of the docking hole is movably connected to the outer wall of the conveying plug rod 12 .

[0033] The crushing device 4 includes a crushing roller 6 rotatably connected to the inner wall of the lower hopper 1 and an auxiliary roller 7 provided on one side of the crushing roller 6 . Both ends of the crushing roller 6 are movable to penetrate the front and rear sides of the lower hopper 1 .

[0034] The crushing roller 6 penetrates through the outer wall of one end of the front side of the lower hopper 1 and is rotatably connected to a pulley 16 through a first transmission belt 13 , and one end of the pulley 16 is fixedly connected to one end of the sector gear 11 .

[0035] Example 2

[0036] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the crushing roller 6 penetrates the outer wall of one end of the back of the lower hopper 1 and is rotatably connected to the outer wall of one end of the second reciprocating tooth rack 18 through the second transmission belt 17. When the first reciprocating tooth rack 10 moves back and forth laterally, the second reciprocating tooth rack 18 also moves synchronously driven by the second transmission belt 17, so that the conveying plug rod 12 can be evenly stressed and the dredging work can be kept running smoothly.

[0037] The crushing roller 6 and the auxiliary roller 7 penetrate through the outer wall of the lower hopper 1 , and are both fixedly connected to the outer wall with a gear 8 . The two sets of gears 8 are meshed with each other. One end of the crushing roller 6 is fixedly connected to a driving motor 9 .

[0038] One end of the sector gear 11 is rotatably connected to the outer wall of the lower hopper 1 , and the upper and lower sides of the first reciprocating tooth rack 10 and the second reciprocating tooth rack 18 are slidably connected to the guide plate rack 15 , and the back side of the guide plate rack 15 is fixedly connected to the outer wall of the lower hopper 1 .

[0039] The material discharge port of the lower hopper 1 is located above the conveyor belt 2 , and a material guide inclined plate 5 is fixedly connected to the inner wall of the lower hopper 1 located above the crushing roller 6 .

[0040] The working principle of the automatic feeding device for sludge treatment is described in detail below.

[0041] like Figure 1-5 As shown, when in use, the dried sludge is put into the lower hopper 1, and the external power supply starts the driving motor 9, so that the driving motor 9 drives the crushing roller 6 to rotate, and the crushing roller 6 drives the auxiliary roller 7 to rotate in the opposite direction through the gear 8 to crush the dried sludge. When the crushed particles are collected at the discharge port of the lower hopper 1 under the action of gravity, the driving motor 9 drives the crushing roller 6 to rotate. The power drives the pulley 16 to rotate through the first transmission belt 13, and the pulley 16 drives the sector gear 11 to rotate. The sector gear 11 rotates, and during the rotation process, it will drive the first reciprocating gear rack 10 to move to one side through the outer wall teeth. Then, after the sector gear 11 flips half a circle, it will drive the first reciprocating gear rack 10 to move to the other side, and so on. When the first reciprocating gear rack 10 repeatedly moves horizontally, the conveying rods 12 at both ends of the first reciprocating gear rack 10 will be driven by it to reciprocate and insert into the discharge port of the discharge hopper 1, so as to clear the dried sludge particles in the discharge port to avoid blockage.

[0042] When the first reciprocating tooth rack 10 moves back and forth laterally, the second reciprocating tooth rack 18 also moves synchronously driven by the second transmission belt 17, so that the delivery rod 12 can be evenly stressed and the dredging work can be kept running smoothly.

[0043] The conveying plug rods 12 on both sides of the discharge port of the discharge hopper 1 are in an alternate insertion state, so that the two sides of the dried sludge in the blocked area are alternately impacted by force, thereby improving the dredging efficiency.

[0044] The guide plate frames 15 installed on the upper and lower sides of the first reciprocating tooth rack 10 guide and limit it so that it can move in parallel to ensure the stability of subsequent operation.

[0045] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
