Description

Technical Field

[0001] This utility model belongs to the field of river dredging technology, and in particular relates to a river dredging sediment and garbage separation device. Background Technology

[0002] River dredging refers to the removal of silt, sand, gravel, and other obstacles from river channels using mechanical or manual means to restore the navigation and flood discharge capacity of the river. During the dredging process, the dredged sediment contains a large amount of gravel and other impurities. To facilitate subsequent processing, separation devices are needed to separate the sediment and debris.

[0003] Currently, commercially available river dredging sediment and waste separation devices still suffer from insufficient or incomplete separation during operation, and the separation speed is relatively slow, resulting in low operating efficiency. Therefore, there is an urgent need to improve existing river dredging sediment and waste separation devices to provide a more efficient one. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a river dredging sediment and garbage separation device that is reasonably designed, simple in structure, provides more thorough separation, faster separation speed, and more efficient operation, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A river dredging sediment and waste separation device includes a support and an outer cylinder. The two ends of the outer cylinder are supported on the tops of two supports respectively. A sludge discharge outlet is opened at the bottom of the left end of the outer cylinder, and a waste discharge outlet is opened at the bottom of the right end of the outer cylinder. A feed pipe is fixed to the upper left of the outer cylinder, and a fixed cylinder is fixed to the inner wall of the left side of the outer cylinder. The upper part of the fixed cylinder is connected to the bottom end of the feed pipe. A separation component is installed on the right side of the fixed cylinder. The separation component includes a horizontal shaft, which is rotatably installed at the center of the outer cylinder and driven to rotate by a motor. A square rod is slidably connected to the right end of the horizontal shaft. A material blocking disc is fixedly connected to the right end of the square rod. The material blocking disc is driven to move by an electric telescopic rod. A separation cylinder with a mesh structure is provided on the outer side of the horizontal shaft. Multiple paddles are fixed in a ring on the inner wall of the separation cylinder. Multiple limiting rods are fixed in a ring on the right end of the separation cylinder. The limiting rods are slidably connected to the material blocking disc.

[0007] Preferably, the left end of the horizontal axis has an eccentrically shaped cavity.

[0008] Preferably, each of the two supports has a through groove inside its top, and a limiting component is provided in the through groove. The two ends of the outer cylinder are respectively connected to the two sets of the limiting components.

[0009] Preferably, the limiting assembly includes a vertical rod, a strong spring, and a movable plate. The two vertical rods are fixed symmetrically in the top through groove of the stand. The two ends of the movable plate are slidably sleeved on the outside of the two vertical rods. The movable plate is slidably located in the top through groove of the stand. Strong springs are provided on the outer sides of both the upper and lower ends of the vertical rods.

[0010] Preferably, the motor is fixedly installed on the outer wall of the middle part of the left movable plate, and the electric telescopic rod is fixedly installed through the middle part of the right movable plate.

[0011] Preferably, the left end of the separating cylinder is rotatably sealed and fitted to the outside of the right end of the fixed cylinder. The separating cylinder and the fixed cylinder are connected by a bearing, and the inner diameters of both are set to increase from left to right.

[0012] Preferably, the material blocking disc is solid and it abuts and seals against the right end opening of the separating cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, when the motor is started to control the rotation of the separation component, multiple paddles fixed at equal angles on the inner wall of the separation cylinder facilitate the high-speed rotation of the bottom sludge. The centrifugal force of the rotation can achieve the initial acceleration of separation. Furthermore, an eccentric cavity is provided inside one end of the horizontal shaft. Due to the uneven force during rotation, the outer cylinder and the two movable plates can reciprocate and rise and fall slightly along the vertical rod, achieving a high-frequency vibration effect, which is beneficial for further accelerating the separation. The bottom sludge and waste are separated at a faster speed, and the device operates more efficiently.

[0015] The separator of this invention has a mesh structure inside. When it rotates and vibrates, the separated bottom sludge can be discharged through the sludge discharge outlet. After complete separation, the electric telescopic rod can be controlled to retract and drive the material blocking disc to move to the right along the limit rod, which opens the right end of the separator. Since the inner diameter of the separator increases from left to right, it is also convenient for the garbage and impurities inside to slide to the right and be discharged through the garbage discharge outlet, which facilitates the discharge and collection of bottom sludge and garbage and is easy to operate.

[0024] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0025] like Figure 1-5 As shown in the figure, the river dredging sediment and garbage separation device of this utility model includes a base 1. A through groove is opened inside the top of the base 1. A limiting component 2 is provided in the through groove. An outer cylinder 5 is provided between two sets of limiting components 2. A feed pipe 6 is fixed on the upper left side of the outer cylinder 5. A fixing cylinder 7 is fixed on the inner wall of the left side of the outer cylinder 5. The bottom end of the feed pipe 6 is connected to the fixing cylinder 7. A separation component 8 is installed on the right side of the fixing cylinder 7. A sludge discharge outlet 9 is opened at the bottom left end of the outer cylinder 5. A garbage discharge outlet 10 is opened at the bottom right end of the outer cylinder 5.

[0026] As a preferred embodiment, based on the above structure, the limiting component 2 further includes a vertical rod 21, a strong spring 22, and a movable plate 23. The two vertical rods 21 are fixed symmetrically in the top through groove of the stand 1. The two ends of the movable plate 23 are respectively slidably sleeved on the outside of the two vertical rods 21. The movable plate 23 is slidably located in the top through groove of the stand 1. Strong springs 22 are provided on the outer sides of both the upper and lower ends of the vertical rods 21.

[0027] As a preferred embodiment, based on the above structure, a motor 3 is fixedly installed on the outer wall of the middle part of the left movable plate 23, and an electric telescopic rod 4 is fixedly installed through the middle part of the right movable plate 23.

[0028] In this embodiment, by setting the limiting component 2, when the starting motor 3 controls the separation component 8 to rotate, it can control the outer cylinder 5 to vibrate at high frequency, which is beneficial to the accelerated separation of bottom mud and the device has higher operating efficiency.

[0029] In a preferred embodiment, based on the above structure, the separation component 8 further includes a horizontal shaft 81, a cavity 82, a square rod 83, a material blocking disc 84, a separation cylinder 85, a paddle 86, and a limiting rod 87. The horizontal shaft 81 is rotatably mounted at the center of the outer cylinder 5. The left end of the horizontal shaft 81 is fixedly connected to the output end of the motor 3. The cavity 82 is eccentrically opened inside the left end of the horizontal shaft 81. The square rod 83 is slidably connected inside the right end of the horizontal shaft 81. The material blocking disc 84 is fixedly connected to the right end of the square rod 83. The material blocking disc 84 is connected to the extension end bearing of the electric telescopic rod 4. The separation cylinder 85 is provided on the outer side of the horizontal shaft 81. Multiple paddles 86 are fixedly fixed in a ring on the inner wall of the separation cylinder 85. Multiple limiting rods 87 are fixedly fixed in a ring on the right end of the separation cylinder 85. The limiting rods 87 are slidably connected to the material blocking disc 84.

[0030] As a preferred embodiment, based on the above structure, the left end of the separating cylinder 85 is rotatably sealed and fitted to the outside of the right end of the fixed cylinder 7. The separating cylinder 85 and the fixed cylinder 7 are rotatably connected by a bearing, and the inner diameters of both are set to increase from left to right. The interior of the separating cylinder 85 has a mesh structure.

[0031] In this embodiment, when the separation cylinder 85 is rotated, multiple paddles 86 arranged at equal angles can be used to drive the bottom mud to rotate at high speed, thereby using the centrifugal force generated by the rotation to accelerate the separation effect.

[0032] As a preferred embodiment, based on the above structure, the material blocking disc 84 is solid and it abuts and seals against the right end opening of the separating cylinder 85.

[0033] In this embodiment, the material blocking disc 84 is used to seal the opening at the right end of the separation cylinder 85, ensuring the complete separation of bottom mud and garbage impurities. Furthermore, the opening at the right end of the separation cylinder 85 can be opened by retracting the electric telescopic rod 4 and moving the material blocking disc 84 to the right along the limiting rod 87, thus facilitating the discharge of the separated garbage impurities.

[0034] The working principle of this utility model is as follows:

[0035] In use, the bottom sludge dredged from the river is first added to the fixed cylinder 7 and the separation cylinder 85 through the feed pipe 6. Then, the motor 3 is turned on to control the entire separation assembly 8 to start rotating at high speed. Multiple paddles 86 fixed at equal angles on the inner wall of the separation cylinder 85 facilitate the high-speed rotation of the bottom sludge. The centrifugal force generated by the rotation helps to achieve the initial acceleration of separation. In addition, a cavity 82 is eccentrically opened at one end of the horizontal shaft 81. Due to the uneven force during rotation, the outer cylinder 5 and the two movable plates 23 can reciprocate and rise and fall slightly along the vertical rod 21, which can achieve a high-frequency vibration effect, which is conducive to further accelerating the separation. The bottom sludge and garbage separation speed is faster, the device operation efficiency is higher, and the separated bottom sludge can be smoothly discharged through the sludge discharge port 9.

[0036] After the bottom mud and garbage impurities are completely separated, the material blocking disc 84 can be moved to the right along the limit rod 87 by the retraction of the electric telescopic rod 4, opening the right end opening of the separation cylinder 85. Since the inner diameter of the separation cylinder 85 increases from left to right, it is also convenient for the garbage impurities inside to slide to the right and be discharged from the device through the garbage discharge outlet 10. The device has a simple structure, faster separation speed, and is easy to operate.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
