Description

Technical Field

[0001] This utility model relates to the field of single cone dryer technology, specifically a single cone dryer with a sampling mechanism. Background Technology

[0002] As is well known, a single cone dryer with a sampling mechanism is a device that integrates sampling function on the basis of a traditional single cone dryer. It is mainly used for drying and sampling analysis of powder materials in the pharmaceutical, chemical and other fields.

[0003] However, existing single-cone dryers with sampling mechanisms usually require stopping the machine first, then separating the cover plate from the machine body before sampling can be performed. This sampling method interrupts the drying process, resulting in reduced equipment efficiency. For example, traditional equipment requires a 15-30 minute shutdown for each sampling, which extends the overall drying cycle by 15%-20%. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a single-cone dryer with a sampling mechanism.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a single-cone dryer with a sampling mechanism, comprising a body, a support frame, a cover plate, and a sampling mechanism. The support frame is disposed on the body, and the cover plate is connected to the body by bolts. The sampling mechanism includes a sampling port, a connecting column, an external thread, a circular plate, an iron plate, an iron ring, and an electromagnet. The sampling port is disposed on one side of the top of the cover plate and communicates with the interior of the body. The external thread is disposed on the outer wall of the connecting column, and the circular plate is threadedly connected to the connecting column through the external thread. One end of the electromagnet is connected to the bottom of the iron plate, and the other end of the electromagnet is attracted to the inner wall of the iron ring. The inner diameter of the iron ring matches the outer diameter of the iron plate.

[0008] To facilitate the limiting of the connecting column, the present invention is improved by including a slide rail, a slider, a threaded rod, and a motor in the sampling mechanism. The slide rail is fixedly connected to the top of the cover plate, one end of the slider extends into the slide rail, the motor is located on one side of the slide rail, the output end of the motor is connected to one end of the threaded rod, the other end of the threaded rod passes through the slider, the threaded rod is located in the slide rail, and the threaded rod is threadedly connected to the slider.

[0009] To facilitate equipment operation, this utility model is improved by providing a controller at the bottom of the support frame, the controller being connected to the motor.

[0010] To facilitate pulling the connecting column, the present invention is improved by providing a handle at the top of the connecting column, and the handle is welded to the top of the connecting column.

[0011] To improve stability, this invention is improved by matching the slider with the slide rail.

[0012] To improve the strength of the support frame, this utility model is improved by using alloy steel as the support frame material.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a single cone dryer with a sampling mechanism, which has the following beneficial effects:

[0015] This single-cone dryer with a sampling mechanism features a design that allows for material sampling without stopping the machine. The sampling mechanism, which uses a detachable connection between an iron ring and an iron plate, allows for quick separation of the iron ring and plate by simply disconnecting the electromagnet's attraction force after sampling, enabling the material to be discharged smoothly. This design effectively avoids the process interruption caused by traditional machine stoppage sampling, reducing the sampling time from 15-30 minutes in the traditional method to less than 2 minutes, significantly improving the machine's working efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A single-cone dryer with a sampling mechanism includes a body 1, a support frame 2, a cover plate 3, and a sampling mechanism 4. The support frame 2 is mounted on the body 1, and the cover plate 3 is connected to the body 1 by bolts. The sampling mechanism 4 includes a sampling port 5, a connecting column 6, an external thread 7, a circular plate 8, an iron plate 9, an iron ring 10, and an electromagnet 11. The sampling port 5 is located on the top side of the cover plate 3 and communicates with the interior of the body 1. The external thread 7 is located on the outer wall of the connecting column 6, and the circular plate 8 is threadedly connected to the connecting column 6 through the external thread 7. One end of the electromagnet 11 is connected to the bottom of the iron plate 9, and the other end of the electromagnet 11 is attracted to the inner wall of the iron ring 10. The inner diameter of the iron ring 10 matches the outer diameter of the iron plate 9.

[0023] Working principle: Place the equipment in the designated position and support it firmly with the support frame 2. Then connect the equipment to the external mains power to complete the power supply connection. Connect the pipes on the equipment to the pipes of the designated external equipment. The machine body 1 is a conventional single cone dryer on the market. Its specific structure will not be described in detail here. The cover plate 3 is equipped with a stirring assembly, which includes a motor 15, a connecting shaft and fan blades, etc. The specific details will not be elaborated here.

[0024] like Figure 1 As shown, the connecting post 6 is inserted into the sampling port 5. When the connecting post 6 extends into the sampling port 5, the circular plate 8 contacts the top of the sampling port 5. At this time, the iron ring 10 and the iron plate 9 cooperate with each other and are aligned with the bottom of the sampling port 5, thereby achieving a seal on the sampling port 5 and effectively preventing material leakage from the sampling port 5. The inner wall of the sampling port 5 is fitted with a 2mm thick high-temperature resistant silicone sealing ring (temperature resistance ≥250℃, Shore hardness 60±5A), which forms an interference fit with the outer wall of the iron ring 10. The sealing pressure can reach 0.1MPa, effectively preventing material leakage. This design can increase the friction between the inner wall of the sampling port 5 and the outer wall of the iron ring 10, thereby preventing the connecting post 6 from being easily pulled out of the sampling port 5.

[0025] After completing the above operations, put the material into the machine body 1 and start processing the material. When sampling is required, first pull the connecting column 6 out of the sampling port 5, and then twist the circular plate 8. Since the circular plate 8 is threadedly connected to the connecting column 6 through the external thread 7, after twisting, the circular plate 8 will move upward along the thread on the connecting column 6 until it reaches the top of the external thread 7 on the connecting column 6. Then, insert the connecting column 6 into the sampling port 5 again. At this time, because the circular plate 8 has risen, when the circular plate 8 contacts the top of the sampling port 5, the iron ring 10 and the iron plate 9 have penetrated into the machine body 1, and the material will enter the iron ring 10. Then, pull the connecting column 6 out of the sampling port 5 to separate it from the sampling port 5. This completes the material sampling.

[0026] A waterproof control button (IP65 protection rating) is embedded at the top of the connecting column 6. The electromagnet 11 is powered by a built-in 3.7V lithium battery. Pressing the button cuts off the circuit, demagnetizing the electromagnet 11 and releasing it from its attraction to the iron ring 10. During sampling, personnel must wear heat-resistant protective gloves (≥200℃), hold the iron ring 10 with one hand, and operate the control button with the other to turn off the electromagnet 11. After the electromagnetic attraction disappears, push the connecting column 6 to separate the iron plate 9 from the iron ring 10. At this time, the material in the sampling chamber flows in under gravity. Material receiving equipment (such as graduated glass collection bottles) is provided for subsequent testing and analysis. It should be noted that the stirring component on the cover plate 3 and the sampling mechanism 4 maintain a safe distance in space. Through 3D modeling verification, the minimum distance between the stirring paddle and the sampling mechanism 4 is 80mm. There is no risk of interference during the movement, ensuring that the sampling operation does not affect the normal operation of the stirring function. In addition, the electromagnet 11 is selected as a Class H high-temperature electromagnet with a temperature resistance of ≥200℃. Its insulation system can withstand the long-term high-temperature environment inside the dryer, ensuring the continuous and stable operation of the equipment.

[0027] In this embodiment, the sampling mechanism 4 further includes a slide rail 12, a slider 13, a threaded rod 14, and a motor 15. The slide rail 12 is fixedly connected to the top of the cover plate 3. One end of the slider 13 is embedded in the slide groove of the slide rail 12 and can slide along it. The motor 15 is installed on one side of the slide rail 12, and its output end is coaxially connected to the threaded rod 14. The other end of the threaded rod 14 passes through the slider 13 and is placed entirely in the guide groove of the slide rail 12, forming a threaded transmission engagement with the slider 13. When the connecting post 6 is inserted into the sampling port 5 and the circular plate 8 is pressed against the top of the sampling port 5, the motor 15 is started to drive the threaded rod 14 to rotate. Under the action of the threaded pair, the slider 13 moves smoothly along the axial direction of the slide rail 12 until its lower end face is pressed tightly against the upper surface of the circular plate 8. The position of the connecting post 6 is locked by mechanical limiting, effectively preventing it from detaching from the sampling port 5 due to vibration or airflow impact during the drying process.

[0028] To facilitate automated operation of the equipment, in this embodiment, a controller 16 is fixedly installed at the bottom of the support frame 2. The controller 16 is electrically connected to the motor 15 via a data cable, and can receive the operating status data of the motor 15 in real time, and send control commands such as start / stop and speed adjustment to the motor 15, so as to realize remote control and intelligent management of the motor 15 in the sampling mechanism.

[0029] To facilitate the operation of the connecting column 6, in this embodiment, a handle 17 is vertically welded to the top of the connecting column 6. The handle 17 adopts an arc-shaped structure design and has a knurled surface to increase friction. Its two ends are fixedly connected to the top of the connecting column 6 by a full welding process. The weld height is not less than 2mm to ensure the connection strength and can withstand a tensile force of not less than 50N, meeting the usage requirements of frequent insertion and removal operations during sampling.

[0030] To improve the stability of the sampling mechanism, in this embodiment, the slider 13 and the slide rail 12 are designed with a precision fit. The cross-sectional profile of the slider 13 is completely matched with the groove shape of the slide rail 12, and the fit gap is controlled within the range of 0.05-0.1mm. This ensures that the slider 13 can slide smoothly in the slide rail 12, and effectively avoids shaking caused by excessive gap. It also ensures the limiting accuracy of the connecting column 6, making the entire sampling process stable and reliable.

[0031] In order to improve the structural strength and load-bearing capacity of the support frame 2, in this embodiment, the support frame 2 is made of high-strength alloy steel. The yield strength of the alloy steel is not less than 650MPa and the tensile strength is 850-1000MPa. Through the quenching and tempering process, its internal structure is uniform, and it has good fatigue resistance and compressive deformation resistance. It can stably support the weight of the machine body 1 and internal components and meet the strength requirements of long-term operation of the equipment.

[0032] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
