Description

Technical Field

[0001] This utility model relates to the field of plastic granule production technology, specifically a drying device for manufacturing plastic granules. Background Technology

[0002] The drying process in plastic pellet manufacturing is a critical step to ensure that the moisture content of the raw materials meets the standard (usually ≤0.1%). Traditional hot air circulating drying equipment has significant safety hazards and structural defects: the open tank (surface temperature reaches 80-120℃) is prone to causing burns to personnel during operation, especially when operators accidentally touch the drive mechanism (such as drive shaft, coupling), the instantaneous contact injury risk rate is as high as 0.5 times / thousand hours; at the same time, the tank is mostly made of single-layer stainless steel cylinder (wall thickness 3-5mm), under high temperature (150-200℃) and material accumulation pressure (≥5kN / m²), thermal creep deformation (annual deformation >10mm) is prone to occur in the middle section, resulting in sealing failure and decreased thermal efficiency (energy consumption increased by 15%).

[0003] For example, a Chinese patent discloses a drying device for plastic granules (authorization announcement number CN221706034U). This patented technology can solve the problems of plastic granules accumulating inside the drying chamber during use in some current devices, which easily affects the overall drying efficiency, and the difficulty in properly discharging plastic granules after use, leading to material loss. However, the drive mechanism and main body of this device lack protective equipment, resulting in low safety during use. Therefore, this utility model provides a drying device for manufacturing plastic granules to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for manufacturing plastic granules, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drying apparatus for manufacturing plastic granules includes a base plate, a tank body mounted on the upper surface of the base plate, a drive mechanism mounted on the outer end of the tank body, a protective mechanism for shielding and protecting the drive mechanism slidably connected to the outer end of the tank body, a lubrication mechanism for lubricating the drive mechanism installed inside the protective mechanism, and a positioning mechanism for restricting the movement of the protective mechanism installed inside the base plate.

[0007] As a further embodiment of this utility model, the protective mechanism includes four sets of sliders, all of which are slidably connected to the inside of the base plate. An L-shaped connecting plate is installed on the upper surface of the slider. Two sets of arc-shaped protective plates are slidably connected to the outer surface of the tank body, and the two sets of arc-shaped protective plates are respectively installed on the upper surface of the four sets of L-shaped connecting plates.

[0008] As a further embodiment of this utility model, the positioning mechanism includes a fixing rod, which is installed inside the base plate, and the left and right sides of the fixing rod are respectively engaged with the interiors of the two sets of sliders.

[0009] As a further embodiment of this utility model, the lubrication mechanism includes a fixed sleeve, which is slidably connected inside the arc-shaped protective plate, and a sponge is installed inside the fixed sleeve.

[0010] As a further improvement of this utility model, an arc-shaped limiting plate is slidably connected to the top of the arc-shaped protective plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When this utility model is in use, by pushing two sets of arc-shaped protective plates, the two sets of arc-shaped protective plates slide at the outer end of the tank body. During the sliding process, the two sets of arc-shaped protective plates shield the drive mechanism and the tank body, thereby effectively isolating the staff from contact with the moving parts and reducing the risk of mechanical injury, thus improving the safety of the device during use. By installing two sets of fixing rings on the outer surface of the tank body, the two sets of fixing rings support the middle section of the tank body during use, thereby minimizing the bending of the middle section of the tank body when pressed, thus improving the service life of the tank body.

[0013] 2. In use, this utility model involves pushing the fixing sleeve to engage the sponge with the inner wall of the annular groove of the arc-shaped protective plate, bringing the lower surface of the sponge against the outer surface of the teeth of the gear ring. Then, by pouring lubricating oil into the fixing sleeve, the gear ring, during rotation, squeezes the sponge, evenly spreading the accumulated lubricating oil onto the outer surface of the gear ring. This eliminates the need for workers to adjust or move the position of the arc-shaped protective plate during lubrication of the gear ring and gears, reducing labor and time and improving the practicality of the device. Furthermore, the fixing sleeve's sliding connection within the groove of the arc-shaped protective plate allows for adjustment and movement of the fixing sleeve and sponge. It also allows the lubrication mechanism to be disassembled during the rotation of the tank body by the drive mechanism, minimizing damage to the lubrication mechanism during tank operation and extending its service life.

[0019] 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.

[0020] Please see Figures 1-4In this embodiment of the utility model, a drying device for manufacturing plastic granules includes a base plate 1, a tank body 2 mounted on the upper surface of the base plate 1, a drive mechanism 3 mounted on the outer end of the tank body 2, a protective mechanism 4 slidably connected to the outer end of the tank body 2 to shield and protect the drive mechanism 3, a lubrication mechanism 5 for lubricating the drive mechanism 3 installed inside the protective mechanism 4, and a positioning mechanism 6 for limiting the movement of the protective mechanism 4 installed inside the base plate 1. The drive mechanism 3 includes a gear 301 and a gear ring 302. Specifically, by mounting the protective mechanism 4 on the outer end of the tank body 2 and then mounting the bottom of the protective mechanism 4 inside the base plate 1, the protective mechanism 4 supports the middle section of the tank body 2 while shielding and protecting it. This minimizes the risk of injury to workers from contact with the drive mechanism 3 and the outer surface of the tank body 2 during the operation of the device, and also prevents the middle section of the tank body 2 from bending when impacted or pressed. This dual design improves the safety and service life of the device during use.

[0021] The protective mechanism 4 includes four sets of sliders 403, all of which are slidably connected to the inside of the base plate 1. An L-shaped connecting plate 401 is installed on the upper surface of the sliders 403. Two sets of arc-shaped protective plates 402 are slidably connected to the outer surface of the tank body 2. The two sets of arc-shaped protective plates 402 are respectively installed on the upper surface of the four sets of L-shaped connecting plates 401. A fixing ring 404 is installed on the inner wall of each of the two sets of arc-shaped protective plates 402. The two sets of fixing rings 404 are slidably connected to the outer surface of the tank body 2. Two sets of slots are opened on the upper surface of the base plate 1. The four sets of sliders 403 are slidably connected to the inside of the two sets of slots of the base plate 1.

[0022] Specifically, by pushing the two sets of arc-shaped protective plates 402, the two sets of arc-shaped protective plates 402 slide at the outer end of the tank body 2, so that the two sets of arc-shaped protective plates 402 shield the drive mechanism 3 and the tank body 2 during the sliding process, thereby effectively isolating the staff from contact with the moving parts, reducing the risk of mechanical injury, and thus improving the safety of the device during use; by installing two sets of fixing rings 404 on the outer surface of the tank body 2, the two sets of fixing rings 404 support the middle section of the tank body 2 during use, thereby minimizing the bending of the middle section of the tank body 2 when pressed, thus improving the service life of the tank body 2.

[0023] The positioning mechanism 6 includes a fixing rod 601, which is installed inside the base plate 1. The left and right sides of the fixing rod 601 are respectively engaged with the interiors of two sets of sliders 403. The fixing rod 601 is installed inside a slot in the base plate 1. A slot is provided on the side of the slider 403 closest to the midpoint of the base plate 1. Connecting blocks 602 are installed on both sides of the fixing rod 601. The positions of the connecting blocks 602 are located on the moving path of the slots inside the sliders 403. The positions of the left and right sides of the fixing rod 601 are respectively close to the two sets of toothed rings 302 near the fixing rod 601. One side remains parallel; specifically, by pushing the two sets of arc-shaped protective plates 402, the internal slots of the two sets of sliders 403 are engaged with the outer end of the connecting block 602, so that the positioning mechanism 6 restricts the movement of the two sets of arc-shaped protective plates 402 and the two sets of fixed rings 404, thereby minimizing the impact between the arc-shaped protective plates 402 and the toothed rings 302 and gears 301 during the process of pushing the arc-shaped protective plates 402 to move, which would cause damage to the toothed rings 302 or gears 301, thus improving the service life of the drive mechanism 3.

[0024] The lubrication mechanism 5 includes a fixed sleeve 501, which is slidably connected to the inside of the arc-shaped protective plate 402. A sponge 503 is installed inside the fixed sleeve 501, and the lower surface of the sponge 503 abuts against the outer end of the toothed ring 302. A groove is provided on the outer surface of the arc-shaped protective plate 402, and the fixed sleeve 501 is slidably connected to the inside of the groove of the arc-shaped protective plate 402. A positioning ring 502 is installed on the outer surface of the fixed sleeve 501, and an annular groove is provided on the inner wall of the groove of the arc-shaped protective plate 402. The position of the annular groove of the arc-shaped protective plate 402 is located on the moving path of the positioning ring 502.

[0025] Specifically, by pushing the fixed sleeve 501, the sponge 503 is engaged with the inner wall of the annular groove of the arc-shaped protective plate 402, and the lower surface of the sponge 503 abuts against the outer surface of the teeth of the gear ring 302. Then, by pouring lubricating oil into the fixed sleeve 501, the gear ring 302, during rotation, squeezes the sponge 503, evenly spreading the accumulated lubricating oil from inside the sponge 503 onto the outer surface of the gear ring 302. This eliminates the need for operators to adjust or move the position of the arc-shaped protective plate 402 during lubrication of the gear ring 302 and gear 301, thereby reducing... This reduces the labor and time required for workers to lubricate gears 301 and gear rings 302, thus improving the practicality of the device. By sliding the fixed sleeve 501 inside the groove of the arc-shaped protective plate 402, the positions of the fixed sleeve 501 and the sponge 503 can be adjusted and moved. This also allows the lubrication mechanism 5 to be disassembled during the rotation of the tank body 2 when the drive mechanism 3 is started, thereby minimizing the risk of damage to the lubrication mechanism 5 during the start-up and use of the tank body 2, and thus extending the service life of the lubrication mechanism 5.

[0026] An arc-shaped limiting plate 7 is slidably connected to the top of the arc-shaped protective plate 402. A groove is provided on the upper surface of the arc-shaped protective plate 402, and the arc-shaped limiting plate 7 is slidably connected inside the groove of the arc-shaped protective plate 402. Specifically, by pushing the arc-shaped limiting plate 7, the lower surface of the arc-shaped limiting plate 7 abuts against the upper surface of the fixed sleeve 501, so that the arc-shaped limiting plate 7 restricts the upward sliding position of the fixed sleeve 501 inside the groove of the arc-shaped protective plate 402, thereby minimizing the upward movement of the sponge 503 during the lubrication of the toothed ring 302, thus improving the stability of the lubrication mechanism 5 during use.

[0027] The working principle of this utility model is as follows:

[0028] When this utility model is in use, by pushing the two sets of arc-shaped protective plates 402, the two sets of arc-shaped protective plates 402 slide at the outer end of the tank body 2, so that the two sets of arc-shaped protective plates 402 shield the drive mechanism 3 and the tank body 2 during the sliding process, thereby effectively isolating the staff from contact with the moving parts and reducing the risk of mechanical injury; by installing two sets of fixing rings 404 on the outer surface of the tank body 2, the two sets of fixing rings 404 support the middle section of the tank body 2 during use, thereby minimizing the bending of the middle section of the tank body 2 when pressed.

[0029] Meanwhile, by pushing the fixed sleeve 501, the sponge 503 is engaged with the inner wall of the annular groove of the arc-shaped protective plate 402, and the lower surface of the sponge 503 is pressed against the outer surface of the teeth of the gear ring 302. Then, by pouring lubricating oil into the inside of the fixed sleeve 501, the gear ring 302 squeezes the sponge 503 during rotation, and the lubricating oil accumulated inside the sponge 503 is evenly applied to the outer surface of the gear ring 302. Thus, the operator does not need to adjust or move the position of the arc-shaped protective plate 402 during the lubrication of the gear ring 302 and the gear 301.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
