Description

Technical Field

[0001] This utility model relates to the field of cement production quality control technology, specifically to an air-cooled hot raw material sampler. Background Technology

[0002] In the cement production process, the quality of hot raw materials plays a decisive role in the performance of the final cement product. Obtaining hot raw material samples and timely testing their chemical composition, particle size distribution, and other indicators are key steps to ensure stable cement production processes and that product quality meets standards.

[0003] Traditional sampling methods for hot raw materials often involve manual sampling using sampling tools, which is inefficient. Furthermore, sampling personnel must be in close contact with and operate the sampler, and due to the inability to effectively insulate against high temperatures, burns and other safety accidents are very likely to occur. During the sampling process, the sampling cylinder also heats up, which not only threatens the safety of operators but also affects the normal use of equipment. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air-cooled hot raw material sampler, comprising a sampling cylinder fixedly mounted on a rotary kiln, an insulating inner cylinder fixedly connected to the side wall of the inner cavity of the sampling cylinder, forming an insulating cavity between the sampling cylinder and the insulating inner cylinder, a support plate fixedly connected to the bottom of one side of the sampling cylinder, an mounting plate fixedly connected to one side of the top of the support plate, an electric telescopic rod mounted on the side of the mounting plate, a fixing rod fixedly connected to the telescopic end of the electric telescopic rod, one end of the fixing rod penetrating the sampling cylinder and extending into the interior of the insulating inner cylinder, an inner conical sampling hopper fixedly connected to the end of the fixing rod extending into the interior of the insulating inner cylinder, a horizontal plate slidably connected to one side of the bottom of one side of the inner conical sampling hopper through a through-hole, a discharge port for use with the inner conical sampling hopper being opened on one side of the top of the horizontal plate, a push rod fixedly connected to one side of the horizontal plate, one end of the push rod penetrating the sampling cylinder and extending into the outside of the sampling cylinder.

[0006] Preferably, the bottom of the sampling cylinder is fixedly connected to a discharge pipe that works in conjunction with the inner conical sampling hopper through a through groove, and one end of the discharge pipe is connected to the bottom of the heat-insulating inner cylinder.

[0007] Preferably, an abutment block is fixedly connected to one end of the push rod extending outside the sampling cylinder, and a blocking block that cooperates with the abutment block is fixedly connected to the top of the support plate and to one side of the mounting plate.

[0008] Preferably, a limiting block that works in conjunction with the inner conical sampling hopper is fixedly connected to the other side of the horizontal plate.

[0009] Preferably, a fan is installed on the side wall of the rotary kiln below the sampling cylinder via a connector. The air outlet of the fan is connected to an air inlet pipe. One end of the air inlet pipe is connected to one side of the bottom of the sampling cylinder, and one side of the top of the sampling cylinder is connected to an air outlet pipe.

[0010] Preferably, the side wall of the rotary kiln has an opening that cooperates with the heat-insulating inner cylinder.

[0011] This utility model provides an air-cooled hot raw material sampler. It has the following beneficial effects:

[0012] This invention achieves automatic sampling of hot raw materials through the cooperation of an electric telescopic rod, an inner conical sampling hopper, a horizontal plate, a push rod, a blocking block, a contact block, and a limiting block. This improves sampling efficiency and meets the needs of real-time and rapid sampling during the production of hot raw materials. It also avoids direct contact between sampling personnel and the high-temperature rotary kiln and the sampling cylinder.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-3This utility model provides a technical solution: an air-cooled hot raw material sampler, including a sampling cylinder 2 fixedly mounted on a rotary kiln 1, an insulated inner cylinder 3 fixedly connected to the side wall of the inner cavity of the sampling cylinder 2, forming an insulated cavity 4 between the sampling cylinder 2 and the insulated inner cylinder 3, a support plate 5 fixedly connected to the bottom of one side of the sampling cylinder 2, an mounting plate 6 fixedly connected to one side of the top of the support plate 5, and an electric telescopic rod 7 mounted on the side of the mounting plate 6. The electric telescopic rod 7 is powered by an external power source, and the telescopic rod 7 extends and retracts... A fixing rod 8 is fixedly connected to the end of the sampling cylinder 2. One end of the fixing rod 8 passes through the sampling cylinder 2 and extends into the interior of the heat-insulating inner cylinder 3. An inner conical sampling hopper 9 is fixedly connected to the end of the fixing rod 8 that extends into the interior of the heat-insulating inner cylinder 3. A horizontal plate 10 is slidably connected to the bottom of one side of the inner conical sampling hopper 9 through a through opening. A discharge port 11 is opened on one side of the top of the horizontal plate 10 to cooperate with the inner conical sampling hopper 9. A push rod 13 is fixedly connected to one side of the horizontal plate 10. One end of the push rod 13 passes through the sampling cylinder 2 and extends into the outside of the sampling cylinder 2.

[0019] The bottom of the sampling cylinder 2 is fixedly connected to a discharge pipe 12 that works in conjunction with the inner conical sampling hopper 9 through a through groove, and one end of the discharge pipe 12 is connected to the bottom of the heat-insulating inner cylinder 3.

[0020] Furthermore, in order to facilitate the discharge of the inner conical sampling hopper 9, a contact block 14 is fixedly connected to one end of the push rod 13 extending to the outside of the sampling cylinder 2, and a blocking block 15 that cooperates with the contact block 14 is fixedly connected to the top of the support plate 5 and to one side of the mounting plate 6.

[0021] Furthermore, in order to enable the horizontal plate 10 to automatically reset, a limiting block 16 that works in conjunction with the inner conical sampling hopper 9 is fixedly connected to the other side of the horizontal plate 10.

[0022] A blower 17 is installed on the side wall of the rotary kiln 1 and below the sampling cylinder 2 via a connector. The blower 17 is powered by an external power source. The air outlet of the blower 17 is connected to an air inlet pipe 18. One end of the air inlet pipe 18 is connected to one side of the bottom of the sampling cylinder 2, and one side of the top of the sampling cylinder 2 is connected to an air outlet pipe 19.

[0023] The side wall of the rotary kiln 1 has an opening 20 that works in conjunction with the heat-insulating inner cylinder 3.

[0024] During operation, the sampling personnel align the hot raw material sample storage frame with the feeding pipe 12, and simultaneously start the blower 17 and the electric telescopic rod 7. The electric telescopic rod 7, through the fixed rod 8, drives the inner conical sampling hopper 9 through the opening 20 of the rotary kiln 1 into the interior of the rotary kiln 1. After the inner conical sampling hopper 9 moves to the appropriate position, wait for the hot raw material to fill the inner conical sampling hopper 9. After the hot raw material is filled, start the electric telescopic rod 7 again to move the inner conical sampling hopper 9 towards the heat-insulating inner cylinder 3. During the movement of the inner conical sampling hopper 9 towards the heat-insulating inner cylinder 3, the contact block 14 at the end of the push rod 13 will abut against the blocking block 15. At this time, the feeding port 11 on the horizontal plate 10 is exactly aligned with the feeding pipe 12, and the inner conical sampling hopper 9 continues to move. When the inlet 11 overlaps, the hot raw material falls into the discharge pipe 12 under the action of gravity, completing the unloading and thus completing one hot raw material sampling operation. During the sampling process, the blower 17 sends air into the heat insulation cavity 4 between the sampling cylinder 2 and the heat insulation inner cylinder 3 through the air inlet pipe 18. After the air flows in the heat insulation cavity 4, it flows out from the air outlet pipe 19, which takes away the heat transferred to the sampling cylinder 2 during the sampling process in time, reducing the temperature of the sampling cylinder 2 and ensuring the safety of the sampling personnel. After the electric telescopic rod 7 drives the fixed rod 8 and the inner conical sampling bucket 9 to move to the initial position, during the movement, the inner conical sampling bucket 9 is attached and the horizontal plate 10 is moved synchronously through the limit block 16, so that the hot raw material sampling operation can continue.
