Description

Technical Field

[0001] This utility model relates to the field of ductile iron cleaning, and more specifically, to a water removal device for ductile iron pipe sockets. Background Technology

[0002] During the production of ductile iron pipes, a large amount of moisture often accumulates in the socket groove after the water grinding process. Traditional methods of water removal mainly rely on air-blowing components to blow water out of the socket. However, this method has significant drawbacks: as the pipe rotates, the blown water is flung everywhere, failing to achieve effective drainage and instead increasing the humidity of the working environment and the difficulty of cleaning. Therefore, there is an urgent need for a ductile iron pipe socket water removal device that combines both blowing and suction functions, achieving precise removal of water accumulated in the socket groove, improving production efficiency, ensuring the socket is thoroughly cleaned without affecting the zinc spraying of the socket and end faces. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a water removal device for ductile iron pipe sockets. This invention removes a large amount of accumulated water from the socket using a water-absorbing component, thus avoiding the problem of excessive water splashing during air blowing. After removing most of the accumulated water, a water-blowing component is used to effectively and concentratedly remove stubborn residual moisture adhering to grooves and crevices, ensuring that the socket area is thoroughly cleaned. This provides a dry and clean surface for subsequent coating processes, greatly improving the corrosion resistance of the product.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1:

[0027] Please see Figure 1-3A ductile iron pipe socket dewatering device includes a dewatering frame and a drive assembly fixedly installed on the dewatering frame. The ductile iron pipe is located at the dewatering station and abuts against a retaining wheel 3. The retaining wheel 3 is installed at the dewatering station. The drive assembly pushes a bearing assembly to move back and forth along the dewatering frame. A water blowing assembly and a water suction assembly are fixedly installed on the bearing assembly in sequence. The water blowing assembly and the water suction assembly extend into the socket of the ductile iron pipe.

[0028] During operation, the ductile iron pipe is transported to the dewatering station. When the ductile iron pipe is located at the dewatering station, the cast part of the ductile iron pipe abuts against the retaining wheel 3 installed at the dewatering station.

[0029] Preferably, the retaining wheel 3 has a built-in sensor. While the retaining wheel 3 limits the ductile iron pipe, the built-in sensor sends a pipe positioning signal to the drive assembly. The drive assembly starts and pushes the carrying assembly to move along the dewatering frame toward the socket of the ductile iron pipe. The water blowing assembly and the water suction assembly are fixedly installed on the carrying assembly. The carrying assembly advances until the water blowing assembly and the water suction assembly extend into the socket of the ductile iron pipe.

[0030] The water-absorbing component draws in the water flow that accumulates inside the socket, while the water-blowing component sprays a high-speed airflow onto the inner wall of the socket, blowing away and peeling off the water adhering to the socket groove and sealing groove.

[0031] After the water removal is completed, the drive component moves in the opposite direction, removing the support component and its blowing and suction components from the socket and returning to the initial position.

[0032] The device provided by this invention requires no manual intervention throughout the entire dewatering process, perfectly matching the production line rhythm, greatly shortening the processing time for a single pipe, and significantly improving the overall efficiency and production capacity of the production line. This invention first removes a large amount of accumulated water from the socket using a water suction component, thus avoiding the problem of excessive water splashing during air blowing. After removing most of the accumulated water, a water blowing component is used to concentrate and effectively target stubborn residual moisture adhering to the grooves and crevices, ensuring that the moisture in the socket area is thoroughly cleaned, providing a dry and clean surface for subsequent processes.

[0033] The dewatering frame includes a support frame and a column 22. The column 22 supports the support frame, and a track 21 is installed on the support frame. The load-bearing components move back and forth along the track 21.

[0034] Preferably, the column 22 is made of I-beams, and the support is moved by a welded rail 21, which is made of channel steel.

[0035] The drive assembly includes a drive cylinder 41, a drive rod 42, and a base 43. The drive cylinder 41 is mounted on the dewatering frame via the base 43. The drive cylinder 41 pushes the drive rod 42, which in turn pushes the load-bearing assembly to move back and forth.

[0036] Under the push or pull of the drive rod 42, the bearing component, carrying the water blowing component and the water suction component, moves back and forth in a straight line along the track 21, thereby realizing the extension and retraction of the water blowing component and the water suction component.

[0037] The supporting components include a connecting rod 51 and a moving platform 52. The driving component pushes the moving platform 52 to move along the dewatering frame. The moving platform 52 is fixedly connected to the connecting rod 51. The water blowing component and the water suction component are both fixedly connected to the connecting rod 51.

[0038] Preferably, the mobile platform 52 is a mobile trolley, and the rollers of the mobile trolley roll along the track 21.

[0039] When the drive component propels the trolley, the trolley moves back and forth by rolling rollers on the track, which improves the accuracy, smoothness and durability of the motion.

[0040] The water blowing assembly includes a blower pipe 61, with several nozzles 62 installed at one end of the blower pipe 61 that extends into the socket of the ductile iron pipe, and the other end of the blower pipe 61 away from the nozzles 62 connected to an air compressor; the air outlets of the several nozzles 62 are arranged opposite to the socket of the ductile iron pipe.

[0041] During operation, the air compressor starts and high-pressure airflow is transported through the air pipe 61. The air pipe 61 blows the airflow from the air source to the ductile iron pipe socket and impacts the inner wall, groove and sealing groove of the ductile iron pipe socket. The airflow blows away the moisture attached to the metal surface.

[0042] The axis of the blower 61 is on the same straight line as the axis of the ductile iron pipe, and the axis of the nozzles 62 are all installed at an angle to the axis of the ductile iron pipe.

[0043] The axis of the blower pipe 61 coincides with the axis of the ductile iron pipe, meaning the blower pipe 61 extends along the centerline of the pipe. The axis of the nozzle 62 is installed at an angle so that the high-pressure airflow is ejected obliquely from the blower pipe 61. This allows the airflow to sweep and advance along the inner wall of the socket, ensuring that the entire inner wall surface from the end to the root of the ductile iron socket is effectively covered and cleaned by the airflow. The method of blowing water into the socket by the water blowing assembly is similar to the water blowing device for cast iron pipe sockets disclosed in patent number CN206300431U, and will not be elaborated here.

[0044] The water absorption assembly includes a conduit 71 fixedly connected to the bearing assembly. A hose 73 is installed inside the conduit 71. Both ends of the hose 73 extend out of the conduit 71. A filter nozzle 74 is installed at the end of the hose 73 near the socket of the ductile iron pipe. The end of the hose 73 away from the filter nozzle 74 is connected to a water collector 75 via a water pump 72.

[0045] Driven by the drive assembly, the bearing assembly delivers the entire water suction assembly to the ductile iron pipe socket. The filter nozzle 74 is aligned with the water accumulation at the bottom of the socket. The water suction pump 72 is started, and the water accumulation in the socket is forced into the filter nozzle 74 and flows quickly to the water collector 75 through the hose 73.

[0046] Preferably, the conduit 71 has a rigid structure, which serves to fix and support the water-absorbing hose 73 and prevent it from bending excessively, wearing out, or falling off during frequent movement.

[0047] This invention uses a drive assembly to propel a carrier assembly back and forth along the dewatering frame. A water-blowing assembly and a water-absorbing assembly are sequentially fixed to the carrier assembly. These components extend into the socket of the ductile iron pipe, preventing the water-blowing assembly from scattering water and thus achieving effective drainage, reducing the humidity of the working environment and the difficulty of cleaning. This invention combines the functions of water blowing and water absorption, achieving precise removal of water accumulated in the socket groove, improving production efficiency, ensuring the socket is thoroughly cleaned, and preventing interference with zinc spraying on the socket and end face.

[0048] Example 2:

[0049] Please see Figure 1-7 A ductile iron pipe socket dewatering device, according to embodiment 1, includes a drainage platform installed below the dewatering station. Side drainage channels 121 are provided on both sides of the drainage platform. A filter slag channel 122 and a water collection channel 124 are provided on the side of the drainage platform closest to the dewatering frame. The two side drainage channels 121 are respectively connected to the two ends of the filter slag channel 122. A slag-separating plate is provided between the filter slag channel 122 and the water collection channel 124. Several water inlets 123 are evenly distributed on the slag-separating plate. The filter slag channel 122 is connected to the water collection channel 124 through the several water inlets 123. The lowest point of the several water inlets 123 is higher than the bottom surface of the filter slag channel 122.

[0050] Preferably, the side drainage channel 121 has a slope, and the lowest point is where the side drainage channel 121 connects to the filter residue channel 122. The drainage platform has a slope, and the water flow converges to the side drainage channel 121 and the filter residue channel 122 on both sides through the slope.

[0051] Wastewater removed from the ductile iron pipe socket first drips or splashes onto the drainage platform, collects in the side drainage channels 121 on both sides, and flows along the side drainage channels 121 to the filter residue tank 122.

[0052] Wastewater enters the filter cake tank 122 from both ends, causing the solid particles carried in the wastewater to settle in the filter cake tank 122. Since there are evenly distributed water inlets 123 on the filter cake tank 122 and the water collection tank 124, the water flows through the water inlets 123 by overflow, and the solid particles carried in the wastewater remain in the filter cake tank 122.

[0053] Preferably, after the water suction component and the water blowing component have finished their operations, when the drive component pushes the carrier component back, the filter nozzle 74 of the water suction component is inserted into the water collection tank 124, the water suction pump 72 is started, and the wastewater is collected into the water collector 75.

[0054] This invention effectively isolates solid impurities outside the drainage system through sedimentation in the filter tank 122 and high-level overflow in the water outlet 123, thus preventing blockages. Furthermore, maintenance personnel only need to clean the filter tank 122 periodically, thereby extending the maintenance cycle of the entire drainage system.

[0055] The filter cake tank 122 is connected to both ends of the two side drainage tanks 121, and buffer chambers 125 are opened at both ends. The length of the buffer chamber 125 extends to the inner wall of the drainage platform. The width of the buffer chamber 125 matches the width of the side drainage tank 121. The bottom surface of the buffer chamber 125 is lower than the lowest point of the side drainage tank 121.

[0056] Wastewater from the side drainage channels 121 first flows into the buffer chamber 125, thereby reducing the water flow velocity. Since the bottom of the buffer chamber 125 is lower than the lowest point of the side drainage channels 121, the water flow velocity decreases sharply when wastewater carrying impurities enters the buffer chamber 125, and larger solid particles in the wastewater preferentially settle at the bottom of the buffer chamber 125 due to gravity.

[0057] After the water flow is slowed down and initially settled in the buffer chamber 125, it flows smoothly into the main body of the filter cake tank 122 from the buffer chamber 125, thus avoiding the high-speed water flow from directly impacting the narrow channel of the filter cake tank 122, thereby preventing the water flow from washing away and stirring up the settled impurities.

[0058] The device provided by this utility model drives the water suction component and the water blowing component to enter and exit the socket through the drive component, and thoroughly removes water by high-pressure airflow stripping and negative pressure suction. It also achieves efficient, water stain-free, and clogging-free cleaning through a multi-stage filtration and drainage system, ensuring quality and environmental protection.
