Description

Technical Field

[0001] This utility model relates to the field of dredging machine technology, specifically a dredging machine for river treatment. Background Technology

[0002] River dredging generally refers to the management of river channels and is a water conservancy project. It uses mechanical equipment to clean and extract silt deposited on the riverbed, thereby clearing the water. The most commonly used dredging machine is the dredging auger, which is used in conjunction with a boat to extract and clean the silt from the riverbed.

[0003] However, existing dredging augers extract both silt and river water simultaneously, with the river water making up a larger proportion. This results in a lengthy process for separating the silt and water after extraction to achieve solid-liquid separation, which reduces dredging efficiency and prevents the silt from being thoroughly cleaned. Utility Model Content

[0004] The purpose of this invention is to provide a dredging machine for river treatment, in order to solve the problem mentioned in the background art that it simultaneously extracts silt and river water, with the river water accounting for a large proportion, which makes the separation of silt and river water after extraction require a long processing time, thereby reducing the efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dredging machine for river treatment, comprising:

[0006] The material extraction pipe includes a first pipe body, one end of which is connected to a material extraction filter cylinder, and the other end of which is connected to a filter cylinder. The filter cylinder is wrapped with a guide pipe, and the other end of the filter cylinder is connected to a discharge pipe. The other end of the discharge pipe is connected to a support frame.

[0010] Preferably, the first tube body and the material extraction filter cylinder, the material extraction filter cylinder and the filter cylinder, and the filter cylinder and the discharge pipe are all connected by flange sealing.

[0011] Preferably, the discharge pipe has a sewage outlet on its outside, and the guide pipe has a waste liquid outlet on its outside.

[0012] Preferably, the output end of the first motor is fixedly connected to the first main shaft, and the outer wall of the first main shaft is fixedly connected to the first auger. Both ends of the first main shaft are rotatably connected to the material extraction filter cylinder and the support frame through ball bearings, and the first motor is fixedly connected to the outer wall of the support frame.

[0013] Preferably, the output end of the second motor is fixedly connected to a first gear, the outside of the first gear is meshed with a second gear, the center of the second gear is fixedly connected to a second main shaft, and the outer wall of the second main shaft is fixedly connected to a second auger.

The second motor is fixedly connected to the outer wall of the discharge pipe via a bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting a partial cylindrical mesh structure, this utility model can filter and return excess liquid during the auger conveying of sludge.

[0022] 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.

[0023] Please see Figure 1-5 One embodiment of this utility model provides: a dredging machine for river treatment, comprising:

[0024] The material extraction pipe 1 includes a first pipe body 11, one end of which is connected to a material extraction filter cylinder 12, and the other end of which is connected to a filter cylinder 14. The filter cylinder 14 is wrapped with a guide pipe 13, and the other end of the filter cylinder 14 is connected to a discharge pipe 15. The other end of the discharge pipe 15 is connected to a support frame 16. With this structure, the extracted sludge can be filtered through the cooperation of the guide pipe 13 and the filter cylinder 14, so that the extracted water source can be filtered and returned.

[0025] The first auger 4 and the second auger 5 are located inside the first pipe body 11 and the material extraction filter cylinder 12, and the second auger 5 is located inside the filter cylinder 14 and the discharge pipe 15. The first motor 2 and the second motor 3 are used to drive the rotation of the first auger 4 and the second motor 3 to drive the rotation of the second auger 5. By setting the first auger 4 and the second auger 5, under the control of the speed difference, the sludge transported by the first auger 4 is continuously squeezed at the second auger 5, thereby further improving the filtration performance of the sludge through the pressure and effectively removing the internal water source.

[0026] Furthermore, both the material extraction filter cylinder 12 and the filter cylinder 14 have a mesh structure, and the mesh diameter of the material extraction filter cylinder 12 is larger than that of the filter cylinder 14. The material extraction filter cylinder 12 is designed to facilitate the extraction of sludge while preventing large impurities from entering the first tube 11. The filter cylinder 14 is designed to filter the water source while preventing sludge from leaking out.

[0027] Furthermore, the first pipe body 11 and the material extraction filter cylinder 12, the material extraction filter cylinder 12 and the filter cylinder 14, and the filter cylinder 14 and the discharge pipe 15 are all connected by flange sealing, which can ensure the sealing and stability of the connection.

[0028] Furthermore, the discharge pipe 15 has a sewage outlet on its exterior, and the guide pipe 13 has a waste liquid outlet on its exterior, so as to realize the discharge of filtered water and the discharge of extracted sludge, respectively.

[0029] Furthermore, the output end of the first motor 2 is fixedly connected to the first main shaft 21, and the outer wall of the first main shaft 21 is fixedly connected to the first auger 4. Both ends of the first main shaft 21 are rotatably connected to the material extraction filter cylinder 12 and the support frame 16 through ball bearings. The first motor 2 is fixedly connected to the outer wall of the support frame 16. The first motor 2 drives the first main shaft 21 to rotate, which in turn drives the first auger 4 to rotate. Through the rotation of the first auger 4, the sludge is extracted and transported.

[0030] Furthermore, the output end of the second motor 3 is fixedly connected to the first gear 31, the outside of which is meshed with the second gear 32. The center of the second gear 32 is fixedly connected to the second main shaft 33, and the outer wall of the second main shaft 33 is fixedly connected to the second auger 5. The inner wall of the second main shaft 33 is connected to the outer wall of the first main shaft 21 through ball bearings, and the outer wall of the second main shaft 33 is rotatably connected to the discharge pipe 15 through ball bearings. The second motor 3 is fixedly connected to the outer wall of the discharge pipe 15 through a bracket. The second motor 3 drives the first gear 31 to rotate, which in turn drives the second gear 32 to rotate, thereby driving the second auger 5 to rotate through the second main shaft 33. The rotation speed of the second auger 5 is less than that of the first auger 4, so that the conveying speed of the first auger 4 to the sludge is greater than that of the second auger 5. As a result, the sludge conveyed by the first auger 4 to the second auger 5 will be squeezed due to the difference in conveying speed, thereby further improving the solid-liquid separation effect.

[0031] Working Principle: The first motor 2, second motor 3, first auger 4, and second auger 5 used in this application are all commercially available products. Their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be described in detail here. When using this utility model, the end of the material extraction filter cylinder 12 of the device is first placed at the bottom of the river silt. Then, the first motor 2 and the second motor 3 are powered on and started. The rotation of the first motor 2 drives the first main shaft 21 and the first auger 4 to rotate. Through the rotation of the first auger 4, the silt is extracted and transported. At the same time, the drive of the second motor 3 drives the first gear 31 to rotate, and further drives the second main shaft 33 to rotate through the second gear 32, thereby realizing the rotation of the second auger 5. When the first auger 4 continuously transports silt to the second auger 5, and because the conveying speed of the second auger 5 is low, the silt continuously accumulates and is squeezed, further removing the liquid in the silt, so that the solid and liquid can be separated efficiently, improving the convenience of subsequent work after silt extraction.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
