Description

Technical Field

[0001] This utility model belongs to the field of mineral resource processing technology, specifically relating to an automatic tailings sampling device. Background Technology

[0002] In mineral processing, tailings, as a major component of beneficiation waste, have physicochemical properties that are of significant reference value for subsequent environmental treatment and resource reuse. To accurately determine the composition, particle size distribution, and moisture content of tailings, regular sampling and testing are typically required.

[0003] Currently, most mineral processing plants still use manual sampling, which involves workers manually placing containers under the tailings outlet to collect the tailings during the operation of the tailings discharge equipment.

[0004] This method is not only labor-intensive, but also prone to unstable sampling and poor representativeness due to the high tailings flow rate and short sampling window time, which affects the accuracy of the test results. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic tailings sampling device. This device can flexibly adjust the receiving posture and has a stable timing control function to improve the automation level and sample representativeness of tailings sampling operations, thus meeting the needs of modern mines for efficient detection and intelligent operation and maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic tailings sampling device includes a support frame installed near the tailings outlet. The support frame includes a platform, one end of which is symmetrically and fixedly connected to a support arm. A tie rod is fixedly connected above the support arm, and both the support arm and the tie rod are connected to the tailings discharge equipment.

[0008] A cylinder is connected to the upper end of the platform, and a pin joint is connected to the telescopic end of the cylinder. A pin arm is connected to the pin joint by bolts.

[0009] One end of the pin arm is connected to a receiving assembly for receiving materials.

[0010] Furthermore, a limiting groove is provided at one end of the pin arm;

[0011] The receiving assembly includes a receiving tube, and a pin plate is fixedly connected to the side of the receiving tube;

[0012] The pin plate is connected to the limiting groove by bolts.

[0013] Furthermore, the top end of the receiving tube is configured as an angled opening;

[0014] The receiving pipe is connected to a guide pipe at its tail end, and a storage tray is placed at the bottom of the guide pipe.

[0015] The feed tube extends into the storage tray.

[0016] Furthermore, the upper end face of the platform is symmetrically provided with fixing holes;

[0017] The bottom of the cylinder is equipped with a fixed foot plate, which is bolted to the platform.

[0018] Furthermore, one end of the support arm has a first connecting hole, and one end of the pull rod has a second connecting hole.

[0019] Furthermore, a protective cover is provided on the upper surface of the platform. The cross-section of the protective cover is U-shaped, and connecting plates are fixedly connected to the bottom of both sides of the protective cover. A third connecting hole is provided through the upper surface of the connecting plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The device is equipped with a cylinder on the platform, and the telescopic end of the cylinder is connected to the material receiving component. By replacing manual operation with an automatic drive structure, it solves the problems of low efficiency and limited sampling window of manual sampling, realizes automatic periodic sampling of tailings, and improves the intelligence level and continuity of sampling work.

[0022] The receiving component in this device adopts an adjustable angle design. The top of the receiving pipe is set with an oblique opening and is connected to the pin plate through a limiting groove. The receiving direction can be flexibly adjusted so that the oblique opening of the receiving pipe is always parallel to the tailings discharge direction. This solves the problem that tailings are difficult to stably enter the receiving pipe in the existing technology and effectively improves the representativeness and uniformity of the sample.

[0023] The device is equipped with a guide pipe and a storage tray. The guide pipe guides the tailings to fall smoothly into the storage tray, avoiding tailings spillage and accumulation, ensuring a clean and orderly sampling process. It solves the problem of tailings splashing and affecting the environment in existing equipment, and improves the safety and cleanliness of the sampling site. Attached Figure Description

The upper end of the platform 11 is connected to a cylinder 2, which serves as a driving element. Its telescopic end is linked to the receiving component 3 through a pin connection structure to complete the automatic sampling action. The power control of the cylinder 2 comes from the back-end timing control module, which can realize automatic periodic driving sampling and improve the stability and consistency of sampling. The telescopic end of the cylinder 2 is connected to a pin connector 22, which is connected to a pin receiving arm 23 by bolts. One end of the pin receiving arm 23 is connected to the receiving component 3 for receiving materials.

[0041] See Figure 4The top of the receiving pipe 31 is set with an angled opening; the tail end of the receiving pipe 31 is connected to the guide pipe 32, and the bottom of the guide pipe 32 is placed in the storage tray 33; the guide pipe 32 extends into the storage tray 33; the receiving pipe 31 is made of stainless steel bent pipe, and the angled opening at the top makes its inlet surface parallel to the tailings outlet surface, effectively increasing the feeding area and reducing tailings leakage; the guide pipe 32 is fixedly connected to the tail end of the receiving pipe 31 by a flange to realize the smooth transmission of tailings, and its pipe is equipped with a wear-resistant lining to reduce long-term wear; the bottom end of the guide pipe 32 is inserted into the upper middle area of ​​the storage tray 33 to prevent sample scattering; the storage tray 33 adopts a closed structure, with a sealing cover and a sampling opening, and has the structural performance of dustproof and pollution-proof, which facilitates the subsequent transfer of samples to the detection area by manual or automatic devices.

[0042] See Figures 2-3 The upper end of the platform 11 is symmetrically provided with fixing holes 111; the bottom of the cylinder 2 is provided with fixing feet 21, which are connected to the platform 11 by bolts; there are four fixing holes 111, which are arranged in pairs on both sides of the platform 11, and the installation positions are symmetrically arranged to ensure that the cylinder 2 is subjected to uniform force; the fixing feet 21 are made of thickened steel plate and are mechanically connected to the platform 11 by high-strength bolts at their lower ends, and are provided with anti-loosening nuts to avoid the risk of loosening during long-term operation; after the cylinder 2 is installed, its axis is consistent with the movement trajectory of the receiving component 3 to ensure linear and stable propulsion.

[0043] See Figure 2 One end of the support arm 12 has a first connecting hole 121, and one end of the tie rod 13 has a second connecting hole 131. The first connecting hole 121 and the second connecting hole 131 are circular through holes, which are fixed to the structural frame of the tailings discharge equipment by bolts to achieve the side-mounted installation of the entire device. The support arm 12 and the tie rod 13 are arranged parallel to each other and maintain a 90° angle with the discharge equipment to enhance the overall structural stability and resistance to lateral interference of the device.

The connecting plates 41 are made of aluminum alloy and are symmetrically arranged at both ends for fixing the protective cover 4 to the platform 11 through the third connecting hole 411. Bolts with washers are installed in the third connecting hole 411 to effectively absorb vibration and prevent the cover from loosening or shifting.

Example

[0045] This embodiment adds a timing control module to the above-mentioned automatic tailings sampling device to realize the function of automatic timing sampling of tailings.

[0046] In this embodiment, an electrical control box assembly is fixedly connected to the side of the platform 11. The electrical control box assembly contains a timer controller and a relay. The timer controller is used to set the working cycle of the cylinder 2, and the relay is used to convert the timer signal into a control signal for the cylinder 2. The cylinder 2 and the electrical control box assembly are electrically connected through wires. The timer controller is connected to the solenoid valve circuit of the cylinder 2. By setting the time interval, the extension and retraction rhythm of the cylinder 2 is controlled, so that the receiving assembly 3 automatically approaches the tailings outlet for sampling according to the preset cycle.

[0047] In timed control mode, the operator can set the sampling cycle parameters on the timer controller according to the tailings discharge rhythm and sampling requirements on site. Once the set time is reached, the timer controller sends a signal to the relay, which triggers the cylinder 2 to move, driving the pin joint 22 and pin arm 23 to move the receiving assembly 3 forward, so that the top bevel of the receiving pipe 31 is aligned with the tailings discharge port below. The tailings enter the receiving pipe 31 directly from the discharge port and flow into the storage tray 33 along the guide pipe 32, completing one sampling process. Then, the cylinder 2 retracts and resets, preparing for the next round of timed sampling.

[0048] Through the above structural design, this embodiment can effectively solve the problems of unstable cycle, high workload and poor real-time performance of traditional manual sampling; through the flexible setting of the timer controller, it can meet the automated sampling requirements of different tailings discharge rhythms; at the same time, by isolating the power signal and pneumatic execution signal through relays, the stability and safety of the device control system are improved, ensuring that the device can still operate stably in complex environments such as high dust and humidity.

[0049] The working principle of this utility model is as follows:

[0050] In use, bolts are installed on the first connecting hole 121 and the second connecting hole 131 to fix it to one side of the tailings discharge equipment, and the telescopic end of the cylinder 2 is facing the tailings discharge port.

[0051] Next, adjust the included angle between the pin arm 23 and the pin connector 22 and the included angle between the receiving pipe 31 and the pin arm 23;

[0052] Make the plane of the inclined opening at the top of the receiving pipe 31 parallel to the plane of the tailings outlet; this will increase the feeding area of ​​the tailings when sampling the tailings.

[0053] When it is necessary to sample the tailings, the cylinder 2 pushes the receiving component 3 to move downwards from the tailings outlet, so that the tailings enter the receiving pipe 31 from the top and flow into the storage tray 33 along the guide pipe 32, thereby completing the sampling operation.

[0054] Furthermore, the timing of cylinder 2 can be set so that sampling can be completed automatically.

[0055] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
