Description

Technical Field

[0001] This utility model relates to the field of coal sample testing, specifically a drying module applicable to automated coal sample processing lines. Background Technology

[0002] When testing coal, it needs to be pulverized into powder. However, coal itself contains moisture, and excessive moisture can affect the test results. Current coal powder drying devices directly blow hot air into the drying chamber to remove the moisture from the coal powder through heat. However, the existing hot air is not blown in evenly, often causing some coal powder to clump together while others still contain a lot of moisture, affecting subsequent processing and testing. In addition, the existing drying chamber can only dry one coal sample at a time, resulting in low overall efficiency.

[0003] Currently, a utility model patent with publication number CN205580169U discloses a coal powder mixing and pre-drying device, including a box body, a bypass air inlet, a sieve plate, and vertical plates. The box body is cylindrical, with connecting flanges at its upper and lower ends. A bypass air inlet is located in the middle of the side of the box body, and a sieve plate with evenly spaced perforations is located at the connection between the bypass air inlet and the box body. Multiple vertical plates are arranged inside the box body in a circumferentially square pattern, with gaps between each plate. In this utility model, bypass air enters the inner side of the vertical plates through the gaps between the plates after passing through the sieve plate, ensuring that the coal powder within the vertical plates is mixed with the bypass air throughout the entire circumference, thus achieving thorough drying of the coal powder. This utility model has a simple structure, is easy to adjust and maintain, and saves resources.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN205580169U involves bypass air entering the inner side of the vertical plate through the gap between the two vertical plates after passing through the screen plate, so that the coal powder in the vertical plate is mixed with the bypass air in the entire circumference, thereby making the coal powder fully dry. However, the circumferentially mixed coal powder needs to maintain a relatively fast flow rate, otherwise it will accumulate in the equipment, causing equipment blockage and affecting the drying effect and drying efficiency of the equipment.

Multiple rake spikes are arranged in a straight line at equal intervals on the lower surface of the coal sample leveling rake. A drying box of the drying components is fixedly installed below the coal sample leveling rake. The upper surface of the drying box... The drying chamber has a feed inlet and an exhaust pipe on its upper surface. The feed inlet is equipped with a feed gate controlled by a cylinder or electric cylinder.

The connecting rod on the electronic weighing device passes through the lower shell of the drying chamber and connects to the weighing tray. The lifting end of the tray lifting cylinder passes through the lower shell of the drying chamber and connects to the inlet and outlet lifting tray. The drying tray rotation mechanism drives the drying tray inside the drying chamber. Five or six coal sample trays are evenly spaced on the drying tray. The drying tray has lifting holes and coal sample tray limiting protrusions at the corresponding positions of the coal sample trays. Air supply guide nozzles are installed on the inner side of the drying chamber on both sides of the drying tray. The blower is connected to the air supply guide nozzles through pipelines.

[0007] In addition, the drying module for automated coal sample processing lines proposed in the above embodiments of this utility model may also have the following additional technical features:

[0010] As a further improvement of this utility model, the drying box, air supply guide nozzle, air guide plate, coal sample tray, coal sample tray limiting protrusion and drying plate are all made of stainless steel.

[0011] As a further improvement of this utility model, the drying oven has one or more built-in temperature sensors.

[0012] By means of the above solution, this utility model has at least the following advantages: Compared with conventional drying equipment, by means of a rotating drying disc and air supply guide nozzles that supply air from both sides, and with the air guide plates built into the air supply guide nozzles, heat can be transferred to the coal sample more evenly, and multiple coal samples can be dried evenly and stably continuously, which can effectively improve the coal sample processing efficiency.

[0019] The following description, in conjunction with the accompanying drawings, describes the drying module of this utility model, which is suitable for automated coal sample processing lines.

[0020] In Embodiment 1 of this application, as Figures 1 to 5As shown, this drying module (hereinafter referred to as "the present invention") applicable to an automated coal sample processing line includes a control cabinet 1, a drying module mounting frame 2, a coal sample rake slide rail 3, a coal sample rake control cylinder 4, a coal sample rake movable support 5, a coal sample rake drive motor 6, a coal sample leveling rake 7, a drying assembly 8, an exhaust pipe 8-1, an inlet gate 8-2, an inlet 8-3, a drying box 8-4, an air supply guide nozzle 8-41, an air guide plate 8-42, a coal sample tray 8-43, a coal sample tray limiting protrusion 8-44, a drying tray 8-45, an air supply fan 8-5, a weighing device 8-6, a tray lifting cylinder 8-7, and a drying unit. The drying module includes a rotating mechanism 8-8, a drying tray lifting base 8-81, a drying tray lifting seat 8-82, a drying tray drive motor 8-83, and a drying tray connecting plate 8-84. A control cabinet 1 is fixedly installed on the side of the drying module mounting frame 2. A coal sample rake slide rail 3 is fixedly installed on the upper inner side of the drying module mounting frame 2. A coal sample rake control cylinder 4 controls the movable support 5 of the coal sample rake to move back and forth on the coal sample rake slide rail 3. A coal sample rake drive motor 6 is fixedly installed at the lower part of the movable support 5 of the coal sample rake. The coal sample rake drive motor 6 drives the disc-shaped coal sample leveling rake 7 to rotate. Multiple rakes are arranged in a straight line at equal intervals on the lower surface of the coal sample leveling rake 7. A drying box 8-4 is fixedly installed below the rake 7, on which the coal sample is flattened. A feed inlet 8-3 is opened on the upper surface of the drying box 8-4, and an exhaust pipe 8-1 is provided on the upper surface of the drying box 8-4. The feed inlet 8-3 is equipped with a feed gate 8-2 controlled by a cylinder or electric cylinder. A blower 8-5, a weighing device 8-6, a tray lifting cylinder 8-7, and a drying tray rotation mechanism 8-8 are fixedly installed in the drying module mounting frame 2 below the drying box 8-4. The drying tray rotation mechanism 8-8 drives the drying tray 8-45 to rotate and lift. An electronic weighing device is fixedly installed on the bracket of the weighing device 8-6. A connecting rod passes through the lower shell of the drying chamber 8-4 and connects to a weighing tray. The lifting end of the tray lifting cylinder 8-7 passes through the lower shell of the drying chamber 8-4 and connects to the inlet / outlet lifting tray. The drying tray rotation mechanism 8-8 drives the drying tray 8-45 inside the drying chamber 8-4. Five or six coal sample trays 8-43 are evenly spaced on the drying tray 8-45. The drying tray 8-45 has lifting holes and coal sample tray limiting protrusions 8-44 corresponding to the positions of the coal sample trays 8-43. Air supply and guide nozzles 8-41 are installed on the inner sides of the drying chamber 8-4 on both sides of the drying tray 8-45. The air supply fan 8-5 is connected to the air supply and guide nozzles 8-41 through a pipeline. The air supply and guide nozzles 8-41 have built-in air guide plates 8-42 and guide vanes.

[0021] A coal powder mixing and pre-drying device (hereinafter referred to as "the patent") with utility model announcement number CN205580169U describes a bypass airflow entering the inner side of two vertical plates through the gap between them after passing through a screen plate. This allows the coal powder in the vertical plates to mix with the bypass airflow in the entire circumference, thus ensuring thorough drying. However, the circumferentially mixed coal powder needs to maintain a relatively fast flow rate; otherwise, it will accumulate inside the equipment, causing blockages and affecting the drying effect and efficiency. This invention, through a rotatable drying disc 8-45 and air supply guide nozzles 8-41 supplying air from both sides, along with air guide plates 8-42 built into the air supply guide nozzles 8-41, allows heat to be transferred more evenly to the coal sample. This enables uniform and stable continuous drying of multiple coal samples, effectively improving coal sample processing efficiency and effectively preventing coal powder accumulation.

[0022] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 5 As shown, the drying tray rotation mechanism 8-8 includes a drying tray lifting base 8-81 and a drying tray connecting plate 8-84. The drying tray lifting base 8-81 is fixedly installed in the drying module mounting frame 2. The lifting cylinder and slide rail installed on the drying tray lifting base 8-81 control the lifting of the drying tray lifting seat 8-82. The drying tray drive motor 8-83 is fixedly installed on the drying tray lifting seat 8-82. The output shaft of the drying tray drive motor 8-83 passes through the lower shell of the drying box 8-4 and connects to the drying tray connecting plate 8-84. The drying tray connecting plate 8-84 is fixedly connected to the center of the drying tray 8-45.

[0023] To further optimize the working efficiency of this application and reduce the difficulty of cleaning, the drying chamber 8-4, the air supply and guide nozzle 8-41, the air guide plate 8-42, the coal sample tray 8-43, the coal sample tray limiting protrusion 8-44, and the drying tray 8-45 are all made of stainless steel. To better sense the temperature inside the drying chamber 8-4, the drying chamber 8-4 is equipped with one or more temperature sensors.

[0024] When in use, install the drying module suitable for the automated coal sample processing line into the corresponding position on the automated coal sample processing line and adapt it to the robotic arm, and the equipment can be put into use.

[0025] When this utility model is used, its specific operation is as follows:

[0026] In operation, the robotic arm of the automated coal sample processing line places the coal sample tray 8-43 directly above the feed inlet 8-3. The feed inlet gate 8-2 opens under the control of an electric or pneumatic cylinder. The tray lifting cylinder 8-7 raises the lifting tray to the feed inlet 8-3. The robotic arm then places the coal sample tray 8-43 onto the lifting tray on the tray lifting cylinder 8-7. Next, the coal sample rake control cylinder 4 pushes the movable support 5 of the coal sample rake along the coal sample rake slide rail 3, bringing the coal sample flattening rake 7 directly above the coal sample tray 8-43 at the feed inlet 8-3. The tray lifting cylinder 8-7 rises again, lifting the coal sample tray 8-43 and inserting the coal sample flattening rake 7 into the coal sample. The rake drive motor 6 drives the disc-shaped coal sample leveling rake 7 to rotate. Multiple rake spikes arranged at equal intervals on the lower surface of the rake 7 simultaneously spread and flatten the coal sample. Then, the tray lifting cylinder 8-7 retracts, lowering the coal sample tray 8-43 onto the drying tray 8-45. At this point, the conical coal sample tray limiting protrusion 8-44 provides guidance and positioning for the coal sample tray 8-43. The coal sample leveling rake 7 resets under the control of the coal sample rake control cylinder 4, the feed inlet gate 8-2 closes the feed inlet 8-3, and the tray lifting cylinder 8-7 lowers below the drying tray 8-45 without obstructing its rotation. At this time, the motor of the drying tray drive motor 8-83, driven by a reducer... The rotating shaft drives the drying tray connecting plate 8-84, which in turn rotates the drying tray 8-45, bringing the newly arrived coal sample tray 8-43 directly above the weighing device 8-6. The cylinder on the drying tray lifting base 8-81 retracts, causing the drying tray lifting seat 8-82 to descend along the slide rail. The descending drying tray lifting seat 8-82 simultaneously lowers the drying tray connecting plate 8-84 and the drying tray 8-45, allowing the top of the weighing device 8-6 to pass through the pre-drilled holes in the drying tray 8-45 and support the coal sample tray 8-43, thus completing the weighing process. Afterwards, the drying tray 8-45 returns to its original position, and the motor of the drying tray drive 8-83, through a reducer and rotating shaft, drives the drying tray connecting plate 8-84, which in turn rotates the drying tray 8-45. 5. The blower rotates at a constant speed, and the blower 8-5 delivers the internally electrically heated hot air through the pipeline to the air supply guide nozzle 8-41. With the assistance of the resistance wire in the pipeline or the air supply guide nozzle 8-41, the temperature is kept ≤50℃. The air supply guide nozzle 8-41 allows the airflow to enter the drying chamber 8-4 evenly and stably. After drying, the coal sample is discharged from the equipment through the exhaust pipe 8-1. After drying for a period of time, the equipment weighs the sample again to determine the weight of the dried coal sample. Finally, the feed gate 8-2 is opened under the control of the electric cylinder or the pneumatic cylinder. The pallet lifting cylinder 8-7 pushes the coal sample pallet 8-43 out of the feed port 8-3, and the robot can then transfer the coal sample pallet 8-43 to the next process.

[0027] In summary, the drying module of this utility model embodiment, applicable to automated coal sample processing lines, uses a rotatable drying tray 8-45 and air supply guide nozzles 8-41 that supply air from both sides, along with the air guide plates 8-42 built into the air supply guide nozzles 8-41, to allow heat to be transferred more evenly to the coal sample. This enables the uniform and stable continuous drying of multiple coal samples, effectively improving coal sample processing efficiency.
