Description

Technical Field

[0001] This utility model relates to the technical field of drying devices, specifically a drying device for spray-applied fire extinguishing materials used in coal mines. Background Technology

[0002] In coal mining operations, fire-prevention and extinguishing materials are often sprayed on mine walls and tunnels to prevent fires. These materials are used to protect the mine walls. If the paint is not dried in time after the wall is painted, excess paint will remain on the surface, resulting in uneven coloring after the paint dries. Therefore, it is necessary to dry the painted wall.

[0003] Currently, most existing paint drying equipment uses a hot air blower to dry the paint directly. However, this method is prone to problems such as insufficient dispersion and uniformity of the hot air flow during the drying process, which can easily lead to drying dead spots, or even local overheating or insufficient drying, thus affecting the quality of the paint. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for sprayable fire extinguishing materials used in coal mines, in order to solve the problem mentioned in the background art that most of the existing paint drying devices directly dry the paint by blowing hot air through a hot air blower. However, this method is prone to problems such as insufficient dispersion and uniformity of the hot air flow during the drying process, which can easily lead to drying dead zones, or even local overheating or insufficient drying, thereby affecting the quality of the paint.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A drying device for sprayable fire extinguishing materials used in coal mines includes two support frames, with a drying mechanism installed on the inner side of each support frame. The drying mechanism includes a lifting frame, with a lifting assembly installed on the inner side of each lifting frame. A drying rack is installed at one end of the lifting assembly. Multiple hot air blowers are installed on the inner side of the drying rack. Multiple air guide plates are rotatably connected to the inner side of the drying rack. A rotating shaft is fixedly connected to one end of each air guide plate. A transmission wheel is fixedly connected to the outer side of each rotating shaft. A synchronous belt drives between every two transmission wheels. A first servo motor is installed at one end of one of the rotating shafts. An activated carbon plate is installed on the inner side of the drying rack, and a disassembly mechanism is installed at one end of the activated carbon plate.

[0007] Preferably, the lifting assembly includes a lead screw, a second servo motor is mounted on the top of the lead screw, an mounting block is threaded onto the outside of the lead screw, the lead screw is rotatably connected to the inner side of the lifting frame, one end of the mounting block is fixedly connected to one end of the drying frame, one end of the drying frame is provided with a sliding groove, and one end of the lifting frame is slidably connected to the inner side of the sliding groove.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0009] This invention uses a cylinder to adjust the distance between two lifting frames until the drying racks are close to the wall, allowing simultaneous drying of two walls. Activated carbon plates absorb moisture from the hot air, improving its dryness. The air guide plate then moves up and down, further dispersing and evenly distributing the hot air flow, reducing dead zones and preventing localized overheating or insufficient drying. The installation frame slides into the inside of the drying rack until one end of the disassembly plate is flush with the rack's surface, allowing the locking block to engage and complete the installation of the activated carbon plate. Replacing the activated carbon plate is simple: just pull the disassembly plate out of the rack. Attached Figure Description

[0015] 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.

[0016] This utility model provides the following technical solution:

[0017] Example 1

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A drying device for sprayable fire extinguishing materials used in coal mines includes two support frames 1, and a drying mechanism 2 is provided on the inner side of the two support frames 1.

[0019] The drying mechanism 2 includes a lifting frame 21, a lifting assembly 22 is provided on the inner side of the lifting frame 21, a drying rack 23 is provided at one end of the lifting assembly 22, multiple hot air blowers 24 are provided on the inner side of the drying rack 23, multiple air guide plates 25 are rotatably connected to the inner side of the drying rack 23, a rotating shaft 26 is fixedly connected to one end of each of the multiple air guide plates 25, a transmission wheel 27 is fixedly connected to the outside of each of the multiple rotating shafts 26, a synchronous belt 28 is connected between every two transmission wheels 27, a first servo motor 29 is installed at one end of one of the rotating shafts 26, an activated carbon plate 204 is installed on the inner side of the drying rack 23, and a disassembly mechanism 3 is provided at one end of the activated carbon plate 204.

[0020] Through the above technical solution, the drying device can enter the mine by moving the entire device via the brake wheel 13. Then, according to the width of the frame, the cylinder 12 on the top of the support plate 11 is activated, causing the cylinder 12 to push another support frame 1, thereby separating the two support frames 1. This allows adjustment of the distance between the two lifting frames 21 until the drying rack 23 at the two lifting frames 21 is close to the wall, thus allowing simultaneous drying of two walls. Then, multiple hot air blowers 24 are activated to blow out hot air, which is then filtered by the activated carbon plate 204 to absorb moisture and improve the dryness of the hot air. Then, the first servo motor 29 is activated to drive a rotating shaft 26 to rotate, which in turn drives an external transmission wheel 27 to rotate, thereby driving the synchronous belt 28 to drive another transmission wheel 27 to rotate. Since every two transmission wheels 2 A synchronous belt 28 is installed between 7, so that when one drive wheel 27 rotates, it can drive the other drive wheel 27 to rotate, thereby causing multiple drive wheels 27 to rotate simultaneously. At this time, the air guide plate 25 connected to the drive wheel 27 also rotates. The first servo motor 29 rotates forward and backward, driving the air guide plate 25 to flip up and down, thereby making the hot air flow more dispersed and uniform, reducing dead corners in the drying process, and avoiding local overheating or insufficient drying. Then, the second servo motor 202 drives the lead screw 201 to rotate, thereby driving the mounting block 203 to move up and down, so that the drying rack 23 can also move up and down. The drying rack 23 is slidably connected to the sliding groove at one end of the lifting frame 21, further improving the stability of the lifting, so that the same position can be dried evenly at different heights, thereby completing the drying operation of sprayed fire extinguishing materials.

[0021] The lifting assembly 22 includes a lead screw 201, a second servo motor 202 is mounted on the top of the lead screw 201, and a mounting block 203 is threaded onto the outside of the lead screw 201.

[0022] The above technical solution enables the drying rack 23 to move up and down, thereby uniformly drying different height positions on the wall.

[0023] The lead screw 201 is rotatably connected to the inside of the lifting frame 21, and one end of the mounting block 203 is fixedly connected to one end of the drying rack 23.

[0024] The above technical solution enables the drying rack 23 to move up and down synchronously when the mounting block 203 is raised and lowered.

[0025] One end of the drying rack 23 is provided with a sliding groove, and one end of the lifting frame 21 is slidably connected to the inner side of the sliding groove.

[0026] The above technical solution provides support for both sides of the drying rack 23, improving the stability of lifting.

[0027] There are multiple hot air blowers 24, and the multiple hot air blowers 24 are arranged in a linear array.

[0028] By employing the above technical solution, multiple hot air blowers 24 arranged in a linear array can improve drying efficiency.

[0029] A battery is installed at one end of each of the multiple hot air blowers 24, the first servo motor 29, and the second servo motor 202.

[0030] Through the above technical solution, the battery can supply power to the hot air blower 24, the first servo motor 29 and the second servo motor 202, ensuring the operation of the hot air blower 24, the first servo motor 29 and the second servo motor 202. The battery power supply method is existing technology, and its working principle is well known to those skilled in the art, so it will not be described in detail.

[0031] Multiple air guide plates 25 are arranged in a linear array, with both ends of the air guide plates 25 penetrating through the drying rack 23 and extending to the inner side of the drying rack 23.

[0032] Through the above technical solution, multiple air guide plates 25 can more effectively guide the hot air, so that the hot air is blown out evenly.

[0033] Each of the two support frames 1 has a support plate 11 fixedly connected to one end. A cylinder 12 is fixedly connected to the top of the support plate 11, and a brake wheel 13 is installed at the bottom of the support plate 11.

[0034] The above technical solution allows for easy movement and stopping of the entire drying process via the brake wheel 13, and the cylinder 12 facilitates adjustment of the distance between the two support frames 1.

[0035] The disassembly mechanism 3 includes a mounting frame 31, one end of which is fixedly connected to a disassembly plate 32, and one end of the disassembly plate 32 is fixedly connected to a locking block 33.

[0036] With the above technical solution, the mounting frame 31 slides into the inside of the drying rack 23 until one end of the disassembly plate 32 is in contact with the surface of the drying rack 23, thereby allowing the locking block 33 to be inserted into the interior of the drying rack 23, completing the installation of the activated carbon plate 204. When disassembling and replacing the activated carbon plate 204, simply pull the disassembly plate 32 to pull the activated carbon plate 204 out of the drying rack 23 for replacement, achieving the effect of facilitating the replacement of the activated carbon plate 204.

[0037] One end of the mounting frame 31 is slidably connected to the inside of the drying rack 23, and one end of the locking block 33 is locked to one end of the drying rack 23.

[0038] Through the above technical solution, the sliding connection method facilitates the smooth entry of the installation frame 31 into the drying rack 23, and the snap-fit ​​method of the locking block 33 allows for subsequent disassembly.

[0039] The working principle of this coal mine spray-on fire extinguishing material drying device is as follows:

[0040] The entire unit enters the mine shaft via the moving device using brake wheels 13. Based on the frame width, cylinder 12 is activated to push the support frame 1 apart, adjusting the distance between the two lifting frames 21 so that the drying rack 23 is close to the wall, simultaneously drying both walls. Multiple hot air blowers 24 are activated to blow hot air, which is filtered through activated carbon plates 204 to absorb moisture and improve drying efficiency. The first servo motor 29 drives the air guide plate 25 to rotate, achieving dispersed and uniform hot air flow, reducing dead zones during the drying process, and preventing localized overheating or insufficient drying.

[0041] The second servo motor 202 drives the lead screw 201 to rotate, causing the mounting block 203 to move up and down, which in turn drives the drying rack 23 to move up and down. The drying rack 23 is connected to the sliding groove of the lifting frame 21 to improve the stability of lifting. The lead screw 201 is rotatably connected to the inside of the lifting frame 21, and one end of the mounting block 203 is fixedly connected to one end of the drying rack 23, so that the drying rack 23 lifts and lowers synchronously. Multiple hot air blowers 24, air guide plates 25, and synchronous belts 28 are arranged in a linear array to improve drying efficiency and hot air uniformity. One end of each of the hot air blower 24, the first servo motor 29, and the second servo motor 202 is equipped with a battery to ensure the operation of the device. The installation frame 31 and the locking block 33 enable convenient installation and replacement of the activated carbon plate 204. This coal mine sprayable fire extinguishing material drying device achieves uniform drying of sprayable fire extinguishing materials through technologies such as hot air drying, air guiding and stirring, stable lifting, synchronous lifting, linear array distribution, and activated carbon plate replacement, thereby improving material quality and performance.
