Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dredging vessels, in particular to a water channel silt treatment device. BACKGROUND

[0002] The screw conveyor (auger) drives the screw blade to rotate in a closed or semi-closed groove through a driving device, and uses the axial thrust of the screw blade to continuously push the silt material falling into the bottom of the groove axially upward, and finally discharges from the discharge port located on the water.

[0003] When conveying river silt with high water content, high viscosity or containing sundries through the auger, internal system blockage often occurs. The common blockage detection method in the prior art is to use a pressure sensor. When the material flows normally inside the auger, the pressure values monitored by each sensor will remain within a stable range. When local blockage occurs, the material flow is blocked, the material behind the blockage point accumulates, causing the pressure in this area to rise significantly; the material in front of the blockage point is pulled empty, causing the pressure in this area to abnormally decrease.

[0004] However, the pressure sensor cannot accurately determine the specific location of the blockage. The propagation of the pressure signal has hysteresis and dispersion in a non-ideal fluid, and the pressure change detected by the sensor reflects the state of the region rather than the exact point, making it difficult to accurately locate the specific spiral or narrow section where the blockage occurs. At the same time, the natural fluctuation of the pressure background value caused by the change in the nature of the silt material itself and the fluctuation of the conveying speed will easily produce interference signals, leading to false alarms or missed alarms. Therefore, relying solely on the pressure sensor for blockage positioning, its accuracy and reliability often cannot meet the needs of efficient and automated dredging operations. SUMMARY

[0005] In order to improve the above problems, the present application provides a water channel silt treatment device.

[0006] The water channel silt treatment device provided by the present application adopts the following technical scheme: A water channel silt treatment device, comprising: A rotating drum and a material conveying tower, the rotating drum is arranged at the bottom of the material conveying tower and communicates with the material conveying tower; the rotating drum is used to convey silt into the material conveying tower; An auger is rotatably arranged in the material conveying tower and used to convey silt upward; A connecting rod and a pressure piece, a plurality of groups of connecting rods are arranged vertically in the material conveying tower; the connecting rod is fixedly connected with the pressure piece, and the connecting rod is slidingly connected with the material conveying tower; the pressure piece abuts against the silt in the material conveying tower; A contact switch group is arranged on the contact surface of adjacent connecting rods, and the contact switch group comprises at least two contact switches, and the two contact switches are connected in series; A plurality of discharge windows are arranged vertically on the side of the material conveying tower, and a blocking window is arranged in the discharge window in a sliding manner. A second magnetic sheet is arranged in the discharge window in a fixed manner, and the blocking window is moved by magnetic adsorption of the second magnetic sheet. The contact switch group is electrically connected to the second magnetic sheet.

[0007] Optionally, the rotating drum comprises a barrel frame and a rotating shaft arranged in the barrel frame in a rotating manner, and a plurality of rotating plates are arranged on the side of the rotating shaft in a fixed manner. A cavity is arranged at the bottom of the rotating drum, and the rotating drum is fixedly connected to the bottom end of the material conveying tower and communicates with each other.

[0008] Optionally, a shovel plate is arranged at the end of the rotating plate in a fixed manner.

[0009] Optionally, at least one contact switch is arranged on the top surface and the bottom surface of the connecting rod respectively; one of the contact switches is in contact with the adjacent connecting rod and is turned on, and the other contact switch is turned off after being in contact with the adjacent connecting rod.

[0010] Optionally, the contact switch arranged at the top of the connecting rod is turned on after being in contact with the adjacent connecting rod, and the contact switch arranged at the bottom of the connecting rod is turned off after being in contact with the adjacent connecting rod.

[0011] Optionally, a connecting groove is arranged on the inner wall of the material conveying tower, and the connecting rod is arranged in the connecting groove in a sliding manner; a compression spring is arranged in the connecting groove in a fixed manner and is fixedly connected to the connecting rod; and a first magnetic sheet is arranged in the connecting groove in a fixed manner, and the connecting rod is moved by magnetic adsorption of the first magnetic sheet.

[0012] Optionally, a sliding groove is arranged at the bottom of the discharge window, and the blocking window is arranged in the sliding groove in a sliding manner; a reset spring is arranged in the sliding groove in a fixed manner and is fixedly connected to the blocking window.

[0015] Optionally, a plurality of net bags are arranged on the side of the material conveying tower in a fixed manner, and the net bags are arranged below the discharge window.

[0016] In summary, the present application has at least one of the following beneficial technical effects: 1. When the blockage occurs in the feeding tower, the material above the blockage surface is less, and the material below the blockage surface is more, which causes the displacement distance of the connecting rod above the blockage surface to be greater than that of the connecting rod below the blockage surface. When the adjacent connecting rods have displacement difference, the contact switch of the connecting rod with greater displacement is closed at the same time due to the loss of the pressure of the adjacent rod, and the circuit is turned on.

[0017] 2.

The blocked material is discharged from the window to the net bag under the extrusion of the auger, and the blocked material is effectively discharged.

[0018] 3. Only when the displacement difference exists continuously, the dredging is triggered, the local pressure fluctuation caused by the temporary gap or loose of the material is effectively filtered, and the false alarm rate is reduced. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0023] The application will be further described below in combination with the accompanying drawings. Figures 1-3 The application will be further described below in combination with the accompanying drawings.

[0024] The embodiment of the application discloses a waterway sludge treatment device. The waterway sludge treatment device comprises a rotating drum 1 and a feeding tower 2.

[0025] The rotary drum 1 comprises a barrel frame 3, a rotating shaft arranged in the barrel frame 3, and a plurality of rotating plates 5 arranged on the rotating shaft. The width of the rotating plate 5 is consistent with the length of the rotary drum 1. The end of the rotating plate 5 away from the rotating shaft is fixedly provided with a shovel plate 4. The rotary drum 1 is fixedly provided with a motor 6 for driving the rotating shaft to rotate. The output end of the motor 6 is coaxially fixedly connected with the rotating shaft. Preferably, the rotary drum 1 is fixedly provided with a barrel body, and the motor 6 is fixedly arranged in the barrel body. The rotary drum 1 is provided with a fan-shaped cavity 7 at the bottom, so that when the rotating plate 5 rotates to the position below the rotary drum 1, the shovel plate 4 is in contact with the silt at the bottom of the water channel. After the rotating plate 5 rotates to the horizontal position, the silt falls onto the surface of the rotating plate 5 by the shovel plate 4.

[0026] The rotary drum 1 is fixedly connected with the bottom end of the material conveying tower 2 and communicates with each other. The bottom of the material conveying tower 2 is provided with an inclined surface at the communication position. After the rotating plate 5 rotates to the vertical upward position, the silt material will fall onto the back of the adjacent rotating plate 5 during the continuous rotation process, and will rotate to the inclined downward position together with the adjacent rotating plate 5. Finally, the silt material slides from the rotating plate 5 to the inclined surface at the bottom of the material conveying tower 2 and enters the material conveying tower 2.

[0027] The auger 8 is vertically arranged in the material conveying tower 2. A plurality of pressing components are arranged in the material conveying tower 2 in the vertical direction. The pressing component comprises two oppositely arranged pressing pieces 9. The cross section of the pressing piece 9 is arc-shaped. The connecting rod 10 is fixedly connected to the side of the pressing piece 9 away from the auger 8. The connecting groove 11 for accommodating the connecting rod 10 is arranged on the inner wall of the material conveying tower 2. The connecting groove 11 is arranged in the vertical direction of the material conveying tower 2. The connecting rod 10 is slidably connected with the connecting groove 11. The horizontal planes of the connecting rods 10 adjacent to each other in the connecting groove 11 are in contact with each other.

[0028] A plurality of compression springs 12 are fixedly arranged in the connecting groove 11. The connecting rod 10 is fixedly connected with the compression spring 12. The compression spring 12 is used to drive the connecting rod 10 to reset to the side close to the auger 8. Preferably, the connecting rod 10 is connected with the inner wall of the connecting groove 11 through dovetail blocks, so that the connecting rod 10 can only slide in the horizontal direction. A plurality of magnetic pieces one are fixedly arranged in the connecting groove 11. The magnetic piece one is an electromagnet. The end face of the connecting rod 10 is provided with a metal piece, so that the magnetic piece one fixes the connecting rod 10 by magnetic adsorption of the metal piece. Specifically, the magnetic piece one is controlled by manual or timer, so that the plurality of magnetic pieces one are de-energized in a unit time and the connecting rod 10 moves to the side close to the auger 8.

[0029] The top surface and the bottom surface of the connecting rod 10 are provided with a contact switch group, which comprises a contact switch one and a contact switch two. The contact switch one comprises a switch groove 14 arranged on the top surface of the connecting rod and a switch piece 15 arranged in the switch groove 14. An elastic piece is arranged in the switch groove 14 and is fixedly connected with the switch piece 15, and is used for driving the switch piece 15 to reset to the outside of the switch groove 14. The contact switch two is arranged on the bottom surface of the connecting rod 10, and the contact switch two has the same structure as the contact switch one, and the contact switch one and the contact switch two are connected in series. The end of the switch piece 15 is a rounded corner, so that the switch piece 15 is received in the switch groove 14 after being pressed by the adjacent connecting rod 10.

[0030] Specifically, after the magnetic sheet one is closed, the compression spring 12 drives the connecting rod 10 and the pressing piece 9 to move towards the direction of the adjacent auger 8. When the material tower 2 is in a smooth state, the material is uniformly distributed in the material tower 2; after the pressing piece 9 moves and contacts the material, the movement of the pressing piece 9 stops. When the material tower is in a blocked state, there is less material above the blocking surface and more material below the blocking surface; the displacement distance of the connecting rod 10 above the blocking surface is greater than that of the connecting rod 10 below the blocking surface. When the displacement distance of the connecting rod 10 is greater than that of the adjacent two connecting rods 10, the switch pieces 15 of the contact switch one and the contact switch two on the connecting rod 10 are extended out of the switch groove 14 under the action of the elastic piece; otherwise, when the displacement distance of the adjacent two connecting rods 10 is similar, the switch piece 15 is received in the switch groove 14 under the pressing action of the adjacent connecting rod 10.

[0031] Specifically, for the contact switch one, when the switch piece 15 is received in the switch groove 14, the contact switch one is in a closed state, otherwise it is in an open state. For the contact switch two, when the switch piece 15 is received in the switch groove 14, the contact switch one is in an open state, otherwise it is in a closed state. Specifically, the two connecting rods 10 located at the position of the blocking surface are in a misaligned state, and the displacement distance of the connecting rod one above the blocking surface is greater than that of the connecting rod two below the blocking surface. The contact switch one on the top surface of the connecting rod one is in a closed state under the pressing action of the adjacent connecting rod three above, and the contact switch two on the bottom surface of the connecting rod one is in a closed state without the pressing action of the connecting rod two. When the contact switch one and the contact switch two are both closed, the circuit is conducted.

[0032] Specifically, when there is no blocking in the material tower 2, the connecting rod 10 at the corresponding position moves towards the direction of the adjacent auger 8 due to the softness or gap of the material in the local area, so that the single connecting rod 10 protrudes from the whole pressing assembly. The switch piece 15 in the contact switch group on the corresponding connecting rod 10 is extended out of the switch groove 14, so that the contact switch one on the top is open and the contact switch two on the bottom is in a closed state, and the circuit is not conducted. The switch pieces 15 on the adjacent two connecting rods 10 are all received in the switch groove 14, and the state of the circuit remains unchanged.

[0033] The material conveying tower 2 is provided with a plurality of groups of material discharging mechanisms on the periphery. The material discharging mechanism comprises two material discharging windows 16 which are oppositely provided on the same plane and are arranged adjacent to the connecting groove 11. The material discharging windows 16 of the plurality of groups of material discharging mechanisms are uniformly distributed along the vertical direction on the periphery of the material conveying tower 2, and the plurality of connecting rods 10 are located in the horizontal height interval of the material discharging windows 16. The top surface of the material discharging window 16 is provided with a sliding groove 17, and the sliding groove 17 is vertically slidably provided with a blocking window 18. The sliding groove 17 is fixedly provided with a reset spring 13 which is fixedly connected with the blocking window 18, and the reset spring 13 is used to drive the blocking window 18 to move downward, so that the material discharging mechanism is in a closed state. The top surface of the sliding groove 17 is fixedly provided with a second magnetic sheet, which is an electromagnet. The top surface of the blocking window 18 is fixedly provided with a metal sheet which can be magnetically attached to the second magnetic sheet; after the second magnetic sheet is electrified, the metal sheet is magnetically attached to the second magnetic sheet, so that the blocking window 18 moves upward, and the material discharging mechanism is in an open state.

[0034] A plurality of contact switch groups located in the horizontal height interval of the material discharging mechanism are connected in parallel and then connected with the second magnetic sheet through a timer and a relay. Specifically, the plurality of contact switch groups are connected in parallel and then connected to the input end of the timer, the output end of the timer is connected to the coil of the relay, and the second magnetic sheet is connected to the normally open contact of the relay. After a single contact switch group is turned on, the timer starts timing and outputs a high level to the relay, and the relay controls the second magnetic sheet to be electrified; after the timer finishes timing, the relay outputs a low level to the second magnetic sheet, and the second magnetic sheet is turned off.

[0035] Specifically, after the abutting piece 9 detects the blocking surface by abutting against the material, the corresponding contact switch group is turned on, the second magnetic sheet located in the height interval is electrified and magnetically attached to the blocking window 18 to rise, and the blocking material is discharged from the material discharging window 16 under the extrusion of the auger 8. After the timer finishes timing, the second magnetic sheet is turned off, the blocking window 18 moves and covers the material discharging window 16 under the action of the reset spring 13, and the material discharging mechanism returns to the closed state.

[0036] Further, a plurality of annular net bags 19 are fixedly arranged on the periphery of the material conveying tower 2, and each material discharging window 16 is provided below the net bag 19. The material discharged from the material discharging window 16 falls onto the net bag 19 and is recycled when the material conveying tower 2 is recycled.

[0037] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
