Description

Technical Field

[0001] This utility model relates to the field of sludge sampling technology, and in particular to a sludge sampling device. Background Technology

[0002] In fields such as environmental monitoring and wastewater treatment, accurate and efficient collection of sludge samples is crucial, as the results directly impact the assessment of water pollution levels and the optimization of subsequent treatment processes. Currently, traditional sludge sampling devices exhibit numerous problems in practical applications that urgently need to be addressed.

[0003] Most existing sampling devices struggle to guarantee sampling depth and accuracy when dealing with sludge of varying characteristics. When encountering severely compacted sludge, ordinary sampling drills, lacking effective breaking structures, struggle to penetrate deep into the sludge, resulting in only surface-level samples that fail to represent the overall sludge condition. Even when some devices manage to drill, precise control of the sampling location is impossible, leading to unrepresentative samples and severely impacting the accuracy of subsequent analyses. Traditional sludge transport pipe designs also have significant flaws. Their diameter is typically fixed, unable to adapt to the viscosity and particle size of the sludge during pump operation. This results in uneven suction distribution during pumping; thicker sludge may fail to be drawn in due to insufficient suction, while smaller diameter sections are prone to blockage due to sludge accumulation, drastically reducing sampling efficiency and making it difficult to ensure the integrity and purity of the collected sludge samples. Furthermore, the stability and durability of traditional sampling devices are unsatisfactory. The support structure is often simply designed, making it difficult to stably support the sampling components in complex sampling environments. This can easily lead to shaking or displacement, affecting the accuracy of the sampling operation. Meanwhile, sampling components, such as drill bits, experience severe wear when in prolonged contact with sludge containing various impurities. Frequent component replacement not only increases costs but also reduces work efficiency. Furthermore, existing devices suffer from poor coordination between components, making it impossible to flexibly adjust their operating status according to the actual conditions during the sampling process, thus failing to adapt to diverse sampling needs.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below.

[0026] This application discloses a sludge sampling device 100, which includes a sludge storage component 11. The sludge storage component 11 is hollow inside, and a sludge outlet is provided on one side of the sludge storage component 11. A sludge outlet switch 111 is provided on the sludge outlet, and several support legs are provided on the lower side of the sludge storage component 11. A telescopic drainage pipe 12 passes through the sludge storage component 11. The drainage pipe 12 is one of a corrugated pipe, a segmented hose, or a hydraulic telescopic pipe. An adjusting cover 121 is provided at the end of the drainage pipe 12 away from the sludge storage component 11, which can control the opening and closing of the drainage pipe 12. The adjusting cover 121 is one of a ball valve, a gate valve, or a stop valve. The size of the opening of the adjusting cover 121 can be adjusted according to the viscosity and particle size of the sludge, thereby cooperating with the suction pump 14 to adjust the suction force and adapt to the sampling of most types of sludge. The support bracket 13 includes several retractable support rods 131, which are connected to the sludge storage component 11 and fixed to the outside of the drainage pipe 12. A support plate 132 is provided at the end of each support rod 131 away from the sludge storage component 11, and the support plate 132 has a through-hole for the drainage pipe 12 to pass through. A suction pump 14 is mounted on the support bracket 13 near the sludge storage component 11 and connected to the drainage pipe 12. The rotary drill shaft 15 includes a drill bit 151, a rotating shaft 152 located on one side of the drill bit 151, and at least three telescopic rods 153 located on the side of the rotating shaft 152 away from the drill bit 151. The telescopic rods 153 are electrically or hydraulically driven and are connected to the side of the support through hole on the support plate 132 away from the drainage pipe 12. When the sampling device 100 is not in use, the rotary drill shaft 15 abuts against the drainage pipe 12 via the telescopic rods 153. When the sampling device 100 is in use, the rotating shaft 152 of the rotary drill shaft 15 rotates first, thereby driving the drill bit 151 to rotate, which in turn drives the sampling device 100 to move downwards towards the sludge. At this time, the support rods 131 extend and retract, and the drainage pipe 12 moves downwards towards the sludge. When encountering large clumps of sludge, the drill bit 151 directly drills into the sludge. The sampling device 100 is operated by breaking up the sludge. Once the sampling depth is reached, the drill bit 151 stops rotating. At this time, the telescopic rod 153 extends and retracts, moving the drill bit 151 and the rotating shaft 152 away from the drainage pipe 12. The adjusting cover 121 on the drainage pipe 12 opens, and the suction pump 14 begins to draw in sludge, thus moving the deep sludge from the drainage pipe 12 into the sludge storage container 11. After the deep sludge sampling is completed, the suction pump 14 stops, and the adjusting cover automatically closes. The user only needs to remove the sampling device 100 from the sludge. A power supply 16 is located on the upper part of the sludge storage container 11 and is electrically connected to the adjusting cover 121, support rod 131, suction pump 14, telescopic rod 153, and rotating drill shaft 15. A control switch 17 is also located on the upper part of the sludge storage container 11 and is electrically connected to the power supply 16. The sampling device 100 of this application uses an electrically or hydraulically driven telescopic rod 153, which can flexibly control the position of the rotating drill shaft 15.When not in use, the rotary drill shaft 15 can abut against the drainage pipe 12 for easy storage. When in use, the rotary drill shaft 15 rotates to drive the drill bit 151 deeper into the sludge, making operation simple. After sampling, the user only needs to remove the device, simplifying the entire sampling process and reducing operational difficulty. When encountering large pieces of coagulated sludge, the drill bit 151 can directly break them up, enabling the device to handle sludge of different states and improving the success rate and applicability of sampling. After reaching the sampling depth, the telescopic rod 153 drives the drill bit 151 and the rotary shaft 152 away from the drainage pipe 12, opens the adjusting cover 121, and the suction pump 14 starts working, smoothly sucking the deep sludge into the sludge storage unit 11, ensuring the sampling depth and the representativeness of the sample. During the sampling process, the start and stop of the suction pump 14 and the adjusting cover 121 can be automatically controlled, reducing manual intervention and improving sampling efficiency and accuracy. The support bracket connects the sludge storage unit 11 and the drainage pipe 12 through several support rods 131 and is equipped with a support plate 132, providing stable support for the device. The fixed collar connection enhances the fixation of the drainage tube 12, ensuring the device remains stable during sampling.

[0027] In one implementation, the diameter of the drainage pipe 12 gradually increases from the side near the regulating cover 121 to the side away from the regulating cover 121. When the suction pump 14 is working, the diameter of the drainage pipe 12 near the regulating cover 121 is smaller. According to the principles of fluid mechanics, under the same suction force, a smaller pipe diameter can increase the fluid velocity at this point, forming a larger suction force, which is more conducive to quickly attracting sludge from a distance into the drainage pipe 12. As the sludge moves towards the sludge storage device 11, the diameter of the drainage pipe 12 gradually increases, the space for sludge flow increases, the flow resistance decreases, and the sludge can flow more smoothly in the drainage pipe 12, thereby improving the overall suction efficiency of sludge from the sludge source to the sludge storage device 11. When large pieces of sludge enter the small-diameter end of the drainage pipe 12 near the regulating cover 121, the larger suction force at this point can break up and disperse the sludge to a certain extent. As the sludge continues to flow towards the gradually increasing diameter part, the increased space reduces the possibility of sludge being squeezed and accumulated, leading to blockage. Even if relatively large sludge lumps enter the drainage pipe 12, as the pipe diameter increases, there is enough space for them to pass through, reducing the risk of the drainage pipe 12 being blocked and ensuring the continuity and stability of the sampling process.

[0028] In one implementation, drill bit 151 employs a helical sawtooth structure with a wear-resistant alloy coating on the sawtooth surface. The diameter of drill bit 151 gradually increases from the tip to the root, and the helix angle of drill bit 151 is 30°-45°. The helical sawtooth structure of drill bit 151 allows the sawtooth to act like multiple cutting edges to break up the sludge as the drill bit 151 rotates. Compared to a conventional flat drill bit 151, the helical distribution increases the contact area and cutting points with the sludge, enabling faster breaking of large sludge pieces into smaller ones, reducing drilling resistance, and increasing drilling speed. The helical shape also guides the broken sludge upwards along the helical grooves, preventing sludge accumulation at the front end of drill bit 151 and affecting drilling efficiency. The helix angle between 30° and 45° is an optimized choice that comprehensively considers drilling efficiency and chip removal capacity. When the helix angle is within this range, drill bit 151 can generate sufficient axial force during rotation to ensure smooth downward drilling while also guaranteeing the smooth discharge of broken sludge along the helical grooves. If the helix angle is too small, chip removal will be impeded, easily causing blockages; if the helix angle is too large, the axial force will be insufficient, reducing drilling efficiency. Sludge may contain various hard particles and impurities, causing severe wear on the saw teeth surface during drilling. Coating with a wear-resistant alloy layer can significantly improve the hardness and wear resistance of the saw teeth, extending the service life of drill bit 151. This means that drill bit 151 does not need frequent replacement during multiple sampling operations, reducing operating costs and maintenance workload.

[0029] In one embodiment, the support bracket 13 includes several fixing rings that can fix the drainage tube 12. When the sampling device 100 is operating, the rotation of the rotary drill shaft 15 and the operation of the suction pump 14 generate vibrations and forces. The fixing rings securely fix the drainage tube 12 to the support bracket 13, preventing the drainage tube 12 from shaking or displacing due to these external forces. This ensures the structural stability of the entire sampling device 100, keeping the relative positions of the components constant, thereby ensuring the normal operation of the sampling work. Multiple fixing rings are distributed along the length of the drainage tube 12, working together to maintain the straight or specific shape of the drainage tube 12.

[0030] In one implementation, several fixed collars are connected together. When the sampling device 100 is operating, the drainage pipe 12 is subjected to various forces, including the suction force of the suction pump 14, sludge resistance, and the vibration of the device itself. When the fixed collars are connected to each other, these forces can be distributed and transmitted among the collars, preventing individual collars from bearing excessive force and being damaged, thereby enhancing the stability of the drainage pipe 12. When the suction pump 14 is vigorously pumping sludge, if the collars are independent, one collar may loosen due to concentrated force. However, the connected collars can share this force, making the drainage pipe 12 more firmly fixed. The connected fixed collars form a relatively rigid integral structure, which helps resist external deformation forces. When the device moves or is subjected to accidental collisions, the rigid structure can reduce the relative displacement between the collars, preventing the drainage pipe 12 from shaking or bending due to collar displacement, ensuring the integrity and stability of the entire sampling device 100 structure.

[0031] As one implementation, a fixing pad is provided on the side of the rotating shaft 152 near the drainage tube 12. During rotation, the rotating shaft 152 inevitably comes into contact with and rubs against the drainage tube 12. The fixing pad, acting as a buffer layer, effectively separates the rotating shaft 152 from the drainage tube 12, preventing direct contact between the rotating shaft 152 and the surface of the drainage tube 12, thus avoiding wear on the drainage tube 12. Especially during long-term sampling operations, this protective effect significantly extends the service life of the drainage tube 12 and reduces the probability of leakage or blockage caused by wear. The fixing pad increases the friction between the rotating shaft 152 and the drainage tube 12, making the drainage tube 12 more stably fixed in its position during device operation. When the sampling device 100 performs drilling, suction, or other operations, the drainage tube 12 will not easily shift or shake due to vibration or other external forces, helping to ensure the accuracy and stability of the sampling. The rotating shaft 152 generates vibrations when it rotates, which are transmitted to the drainage tube 12, affecting the flow of sludge and the sampling effect. The fixing pad has a certain degree of elasticity, which can absorb and buffer the vibrations generated by the rotating shaft 152, reduce the impact of vibrations on the drainage tube 12, and allow the sludge in the drainage tube 12 to flow more smoothly, thereby improving the sampling quality.
