Description

Technical Field

[0001] This utility model relates to the field of oily sludge treatment technology, specifically to an oily sludge treatment residue sampler. Background Technology

[0002] With the rapid development of the petroleum industry and related chemical industries, oily sludge, an unavoidable solid-liquid mixed waste generated during petroleum refining, storage, transportation, and oilfield development, has become a crucial issue in environmental protection and resource recovery. Oily sludge contains large amounts of petroleum hydrocarbons and harmful impurities; improper treatment can not only cause environmental pollution but also affect subsequent resource utilization efficiency. Therefore, scientific and accurate sampling and analysis of residues from oily sludge treatment processes are essential to ensuring both treatment effectiveness and environmental safety.

[0003] Most existing oily sludge sampling equipment has a simple structure and relatively fixed sampling methods, making it difficult to adapt to the complex and varied sampling needs within different sludge tanks. Traditional sampling devices can usually only sample at limited locations, failing to achieve flexible sampling at different depths and in different areas within the sludge tank, resulting in insufficient sample representativeness and affecting the accuracy of subsequent analysis results. Furthermore, some mechanical structures used for sampling oily sludge from treatment tanks are not safe or convenient enough for sample handling.

[0004] Therefore, this solution proposes a sampler for oily sludge treatment residue to address the aforementioned problems. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a sampler for oily sludge treatment residue.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: an oily sludge treatment residue sampler includes a support, a cantilever frame installed at the front end of the support, a telescopic arm installed at the front end of the cantilever frame, a swing arm drive mechanism installed at the front end of the cantilever frame to drive the front end of the telescopic arm to swing around the rear end in an arc shape, a stepping cylinder installed at the front end of the telescopic arm, and a sampling component installed at the end of the piston rod of the stepping cylinder.

[0007] Preferably, the swing arm drive mechanism includes a geared motor, a drive gear, a transmission gear, a synchronous toothed belt, and a docking shaft. The docking shaft is installed at the front end of the cantilever frame and is connected to the rear end of the telescopic arm. The geared motor is installed inside the front end of the cantilever frame. The drive gear is connected to the output end of the geared motor. The transmission gear is installed at the top of the docking shaft. The synchronous toothed belt is tensioned and sleeved between the drive gear and the transmission gear.

[0008] Preferably, the telescopic boom includes an electric push rod, a mounting base, and a telescopic diagonal brace. The tail end of the electric push rod is connected to the drive end of the swing arm drive mechanism, the mounting base is mounted on the front end of the electric push rod, and the telescopic diagonal brace is mounted between the bottom housing of the electric push rod and the mounting base.

[0009] Preferably, the sampling assembly includes a negative pressure pump, a placement cylinder, and a sampling cylinder. The top of the negative pressure pump is mounted on the end of the piston rod of the stepping cylinder, the placement cylinder is mounted on the bottom of the negative pressure pump and its interior is connected to the air extraction end of the negative pressure pump, and the sampling cylinder is installed inside the placement cylinder.

[0010] Preferably, an end cap is screwed to the bottom of the placement tube, and the end cap has a hole in the center for the sampling end of the bottom of the sampling tube to pass through.

[0011] Preferably, both the top of the sampling tube and the top of the placement tube are provided with a channel that communicates with the suction end of the negative pressure pump, a piston is slidably engaged inside the sampling tube, and a downward protruding sampling nozzle is screwed to the bottom of the sampling tube.

[0012] The beneficial effects of this utility model are reflected in:

[0013] This device, equipped with a telescopic arm and its matching electric push rod and stepping cylinder, enables flexible sampling operations at any location inside the oily sludge treatment tank. The telescopic arm's length can be freely adjusted according to actual needs, and combined with the precise advancement of the stepping cylinder, it allows the sampling components to penetrate deep into different areas of the sludge tank, ensuring the representativeness and accuracy of sample collection, and greatly improving the flexibility and applicability of sampling.

[0014] Furthermore, the swing arm drive mechanism, through a reduction motor driving the drive gear, synchronous toothed belt, and docking shaft, enables the front end of the telescopic arm to move along an arc, realizing the swing function of the sampling device. This design not only allows the sampling component to be safely and conveniently swung to the shore after sampling, making it easy for operators to directly retrieve the sampling tube, but also effectively avoids personnel entering dangerous areas, improving operational safety and efficiency.

[0015] The negative pressure pump and piston inside the sampling assembly work together to ensure efficient and sealed sampling of oily sludge residue, preventing sample contamination and leakage, and meeting the quality requirements of subsequent testing. The design of the placement cylinder and swivelable end cap further simplifies the replacement and maintenance process of the sampling cylinder, improving the practicality and ease of operation of the equipment.

[0016] In summary, this oily sludge treatment residue sampler achieves a technological breakthrough in multi-point, deep sampling within sludge ponds through optimized mechanical structure design. Combined with a swingable robotic arm, it significantly improves the safety and ease of operation during the sampling process. This equipment not only meets the demands for efficient and accurate sampling but also greatly reduces the labor intensity and safety risks of on-site operations. It is suitable for diverse sampling and testing tasks in the field of oily sludge treatment and has broad application value and promising market prospects. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0032] It should be noted that if the utility model embodiment involves directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.

[0034] Please refer to the instruction manual appendix. Figures 1-6 This utility model provides a sampler for oily sludge treatment residue. The sampler is based on a support 1, which provides support for the overall frame and ensures the stability of the equipment. A cantilever 2 is provided at the front end of the support 1, which extends forward to support the subsequent mechanical parts.

[0035] The cantilever frame 2 is equipped with a telescopic support arm 4 at its front end. The support arm consists of an electric push rod 41, a mounting base 42, and a telescopic diagonal brace 43. The electric push rod 41 is connected to the swing arm drive mechanism 3 through its tail end. The front end is equipped with a mounting base 42 for fixing the sampling component and supporting the telescopic diagonal brace 43, which provides support stability. The front end of the mounting base 42 is equipped with a stepping cylinder 5 that drives the sampling component 6 to descend into the oily sludge treatment tank. In conjunction with the electric push rod 41, the length of the entire support arm can be telescopically adjusted, allowing the front end to be freely adjusted in distance, thereby enabling the downward sampling operation at any position inside the oily sludge treatment tank.

[0036] The swing arm drive mechanism 3 includes a reduction motor 31, a drive gear 32, a transmission gear 33, a synchronous toothed belt 34, and a docking shaft 35. By starting the reduction motor 31, the drive gear 32 is driven to rotate, which in turn drives the transmission gear 33 and the docking shaft 35 to rotate through the synchronous toothed belt 33. This causes the front end of the telescopic support arm 4 to move along an arc, thereby driving the sampling device to sample at the target oil sludge residue location. At the same time, after the sampling operation is completed, it can be swung to the shore to facilitate the operation of the operator to remove the internal sample.

[0037] The sampling assembly 6 consists of a negative pressure pump 61, a placement cylinder 62, and a sampling cylinder 63. The negative pressure pump 61 is installed at the end of the piston rod of the stepping cylinder 5. It uses the negative pressure generated to draw oily sludge residue into the sampling cylinder 63 inside the placement cylinder 62. The placement cylinder 62 is fixed to the bottom of the negative pressure pump 61 and its interior is connected to the suction end of the negative pressure pump 61. An end cap 621 is screwed onto the bottom end. The end cap has a hole in the center to facilitate the bottom end of the sampling cylinder 63 to pass through for sampling. At the same time, the end cap 621 can be unscrewed so that the sampling cylinder 63, after sampling, can be taken out for subsequent testing operations.

[0038] The sampling cylinder 63 is located inside the placement cylinder 62, and both its top and the top of the placement cylinder 62 have channels that connect to the suction end of the negative pressure pump 61. A piston 632 is slidably mounted inside the sampling cylinder 63, and a sampling nozzle 631 is mounted at the bottom. When the negative pressure pump 61 is started, a negative pressure is formed in the space above the piston 632 inside the sampling cylinder 63, which in turn drives the piston 632 to slide upward, thereby realizing the sampling operation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
