Description
Technical Field
[0001] This invention relates to the field of hydroxypropyl methylcellulose processing technology, specifically to a hydroxypropyl methylcellulose drying device. Background Technology
[0002] Hydroxypropyl methylcellulose (HMCMC) is a semi-synthetic, inactive, viscoelastic polymer commonly used in ophthalmology as a lubricant, or as an excipient or excipient in oral medications, and is found in a wide variety of products. As a food additive, HMCMC can act as an emulsifier, thickener, suspending agent, and substitute for animal gelatin. In the construction industry, HMCMC is used as a water-retaining agent and retarder in cement mortar, improving its pumpability. In plaster, gypsum, putty, and other building materials, it acts as an adhesive, improving spreadability and extending workability. It is used as a bonding agent for tiles, marble, and plastic decorations, and can also reduce cement usage. HMCMC is widely used in the synthetic resin, petrochemical, ceramics, paper, leather, pharmaceutical, food, and cosmetic industries, resulting in significant demand. Drying is an essential processing step in its production.
[0003] In existing equipment, the hydroxypropyl methylcellulose (HMC) tends to clump together during the production process, which prevents the cellulose from drying completely and results in low efficiency. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides: a hydroxypropyl methylcellulose drying device, including a processing cylinder having a cylindrical structure and an annular positioning plate disposed on the outside of the processing cylinder. A support base is fixedly connected to the bottom of the annular positioning plate, a feed frame is fixedly connected to the top of the processing cylinder, a discharge frame is connected to the bottom of the processing cylinder, a support rod is fixedly connected to the inner side of the annular positioning plate near the top, and an arc-shaped opening is provided on one side of the annular positioning plate.
[0005] A dispersing device for dispersing clumps of cellulose, the dispersing device being located inside the processing cylinder;
[0006] A drying device for drying cellulose, the drying device being disposed outside the processing cylinder.
[0007] Preferably, the support base is provided in two sets and symmetrically distributed on the annular positioning plate, the inner wall of the annular positioning plate is fixedly connected to the bottom of the processing cylinder, and the feed frame and the discharge frame are each provided in two sets.
[0008] Preferably, the dispersing device includes a processing sphere and a rotating column. The processing sphere has symmetrical dispersing openings on its outer side. Both ends of the rotating column are rotatably connected to fixed blocks via an electric rotating seat. An arc-shaped support frame is fixedly connected to the outer side of the rotating column. An arc-shaped extrusion plate is fixedly connected to the end of the arc-shaped support frame away from the rotating column. The cellulose to be processed is poured into the processing sphere from the feed frame. Then, the cellulose entering the processing sphere is dried by a drying device. While the cellulose is drying, the electric rotating seat is turned on, which drives the rotating column to rotate. When the rotating column rotates, it drives the arc-shaped support frame to move. The arc-shaped support frame drives the arc-shaped extrusion plate to slide into the processing sphere from the dispersing opening, continuously tapping the cellulose in the processing sphere. Because the two sets of arc-shaped extrusion plates are staggered, they can squeeze and disperse the cellulose clumps in the processing sphere, preventing the cellulose from sticking together during drying.
[0009] Preferably, the dispersing ports are provided in multiple sets and are staggered. The top of the processing sphere is fixedly connected to the bottom of the support rod. The end of the support rod near the processing sphere passes through the processing cylinder and is fixedly connected to the processing cylinder. The end of the fixing block away from the electric rotating seat is fixedly connected to the inner wall of the processing cylinder.
[0010] Preferably, the rotating columns are arranged in two sets and symmetrically distributed on both sides of the processing sphere shell, the arc-shaped extrusion plates correspond one-to-one with the dispersing ports, the arc-shaped extrusion plates are slidably connected to the inner wall of the dispersing ports, the arc-shaped extrusion plates on both sides of the processing sphere shell are staggered, and one end of the feed frame is connected to the processing sphere shell.
[0011] Preferably, the drying device includes an air pump, the air outlet of which is connected to an air outlet pipe. The end of the air outlet pipe away from the air pump is connected to a heating frame, and the end of the heating frame away from the air outlet pipe is connected to an arc-shaped exhaust pipe. An adjustment device is installed at the end of the arc-shaped exhaust pipe away from the heating frame. A connecting frame is fixedly connected to the bottom of the air pump. When the air pump is turned on, external air is drawn into the air outlet pipe and then into the heating frame through the air outlet pipe. The passing gas is heated by the electric heating wire inside the heating frame. The heated gas is discharged from the arc-shaped exhaust pipe through the adjustment device into the processing sphere to dry the cellulose inside. At this time, the air pumping speed can be adjusted. When the air speed is faster, coarser and heavier cellulose can be blown from the dispersing port into the processing cylinder. When the air speed is lower, only fine cellulose can be blown away, which makes it convenient to adjust the air speed according to the required specifications.
[0012] Preferably, an electric heating wire is installed inside the heating frame, the end of the connecting frame away from the air pump is fixedly connected to the outer wall of the processing cylinder, and the arc-shaped exhaust pipe passes through the arc-shaped opening.
[0013] Preferably, the adjusting device includes a first rotating bolt and a second rotating bolt. A first adjusting plate is fixedly connected to the rotating part of the first rotating bolt, and a second adjusting plate is fixedly connected to the fixed part of the first rotating bolt. A third adjusting plate is fixedly connected to the rotating part of the second rotating bolt, and a fourth adjusting plate is fixedly connected to the fixed part of the second rotating bolt. Sealing covers are used between the first and third adjusting plates and between the second and fourth adjusting plates. A first electric push rod and a second electric push rod are rotatably connected to the ends of the first and second adjusting plates away from the first rotating bolt, respectively, via rotating seats. A connecting pipe is passed through and fixedly connected to one side of both the second and fourth adjusting plates. One end of the connecting pipe is connected to an arc-shaped exhaust pipe via an elastic tube. An air inlet is provided on the outer side of the arc-shaped exhaust pipe. The third adjusting plate is passed through and fixedly connected to... An arc-shaped push rod is connected, with a sealing plug fixedly connected to the end of the arc-shaped push rod away from the third adjusting plate. A drying frame is fixedly connected to the fixing parts of the first and second rotating bolts. When the wind speed is high, the first and second electric push rods are activated, causing them to extend continuously. The first electric push rod pushes the first and third adjusting plates, and the second electric push rod pushes the second and fourth adjusting plates, causing the first adjusting plate to rotate around the first rotating bolt and the third adjusting plate to rotate around the second rotating bolt. This continuously expands the sealing cover, gradually increasing the space covered by the sealing cover. The sealing cover expands to a larger space, allowing more air to be contained inside. This ensures that even when the air exits the sealing cover at a faster rate, the air entering the sealing cover still has enough time to fully contact the desiccant filled in the drying frame.
[0014] Preferably, the sealing cover is made of rubber. The end of the first electric push rod away from the first adjusting plate is fixedly connected to the outer side of the heating frame. The end of the second electric push rod away from the second adjusting plate is fixedly connected to the outer wall of the processing cylinder. The end of the arc-shaped push rod near the sealing plug passes through the arc-shaped exhaust pipe and is slidably connected to the arc-shaped exhaust pipe. The sealing plug is slidably connected to the inner wall of the arc-shaped exhaust pipe. When the first electric push rod retracts, it pushes the first adjusting plate and the third adjusting plate to move. The third adjusting plate drives the sealing plug through the arc-shaped push rod to gradually block the air inlet, so that the air inlet can change with the wind speed of the air pump. The lower the wind speed, the smaller the ventilation diameter of the air inlet. When the wind speed is zero, the air inlet is blocked and sealed by the sealing plug. At this time, it can prevent external air from entering the drying frame and reacting with the desiccant when the device is not in use.
[0015] Preferably, the end of the arc-shaped exhaust pipe near the arc-shaped push rod passes through the first adjusting plate, the portion of the arc-shaped exhaust pipe located outside the first adjusting plate is configured as a flexible hose, and the end of the arc-shaped exhaust pipe away from the elastic tube is connected to the processing spherical shell.
[0016] This invention provides a drying device for hydroxypropyl methylcellulose. It has the following beneficial effects:
[0017] 1. This hydroxypropyl methylcellulose drying equipment, through the installation of a dispersing device, pours the cellulose to be processed from the feed frame into the processing sphere shell. Then, the drying device dries the cellulose entering the processing sphere shell. While the cellulose is drying, the electric rotating seat is turned on, which drives the rotating column to rotate. When the rotating column rotates, it drives the arc-shaped support frame to move. The arc-shaped support frame drives the arc-shaped extrusion plate to slide into the processing sphere shell from the dispersing port, continuously tapping the cellulose in the processing sphere shell. Because the two sets of arc-shaped extrusion plates are staggered, they can squeeze and disperse the cellulose that has clumped in the processing sphere shell, preventing the cellulose from sticking together during drying.
[0018] 2. This hydroxypropyl methylcellulose drying equipment, through the installation of the drying device, draws external air into the exhaust pipe by turning on the air pump, and then draws the air into the heating frame through the exhaust pipe. The electric heating wire inside the heating frame heats the passing gas. The heated gas is discharged from the arc-shaped exhaust pipe through the regulating device into the processing sphere to dry the cellulose inside. At this time, the air pump speed can be adjusted. When the air speed is faster, coarser and heavier cellulose can be blown from the dispersing port into the processing cylinder. When the air speed is lower, only fine cellulose can be blown away. It is convenient to adjust the air speed according to the required specifications.
[0019] 3. This hydroxypropyl methylcellulose drying equipment, through the installation of an adjustment device, when the wind speed is high, activates the first and second electric push rods, causing them to continuously extend. The first electric push rod pushes the first and third adjustment plates, and the second electric push rod pushes the second and fourth adjustment plates, causing the first adjustment plate to rotate around the first rotating bolt and the third adjustment plate to rotate around the second rotating bolt, continuously expanding the sealing cover. This gradually increases the space covered by the sealing cover, expanding it to a larger space. At this time, the amount of air that can be contained inside the sealing cover increases, ensuring that even when the air exhaust rate from the sealing cover increases, the air entering the sealing cover still has sufficient time to fully contact the desiccant filled in the drying frame.
[0020] 4. This hydroxypropyl methylcellulose drying equipment, through the setting of an arc-shaped exhaust pipe and a sealing plug, when the first electric push rod retracts, pushes the first adjusting plate and the third adjusting plate to move. The third adjusting plate drives the sealing plug through the arc-shaped push rod to gradually block the air inlet, so that the air inlet can change with the wind speed of the suction pump. The lower the wind speed, the smaller the ventilation diameter of the air inlet. When the wind speed is zero, the air inlet is blocked and sealed by the sealing plug. At this time, it can prevent external air from entering the drying frame and reacting with the desiccant when the device is not in use. Attached Figure Description

Detailed Implementation
[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
[0032] For the first embodiment, please refer to... Figures 1-4 The present invention provides a technical solution: a hydroxypropyl methylcellulose drying device, including a processing cylinder 1, the processing cylinder 1 having a cylindrical structure, and an annular positioning plate 2 disposed on the outside of the processing cylinder 1. A support base 3 is fixedly connected to the bottom of the annular positioning plate 2, a feeding frame 4 is fixedly connected to the top of the processing cylinder 1, a discharge frame 5 is connected to the bottom of the processing cylinder 1, a support rod 6 is fixedly connected to the inner side of the annular positioning plate 2 near the top, and an arc-shaped opening 9 is opened on one side of the annular positioning plate 2.
[0033] Dispersing device 7, which is used to disperse clumps of cellulose, is located inside the processing cylinder 1.
[0034] Drying device 8, which is used to dry cellulose, is located outside the processing cylinder 1.
[0035] Two sets of support bases 3 are provided and symmetrically distributed on the annular positioning plate 2. The inner wall of the annular positioning plate 2 is fixedly connected to the bottom of the processing cylinder 1. Two sets of feed frames 4 and discharge frames 5 are provided.
[0036] The dispersing device 7 includes a processing spherical shell 71 and a rotating column 73. The processing spherical shell 71 has symmetrical dispersing openings 72 on its outer side. Both ends of the rotating column 73 are rotatably connected to fixed blocks 75 via electric rotating seats 74. An arc-shaped support frame 76 is fixedly connected to the outer side of the rotating column 73. An arc-shaped extrusion plate 77 is fixedly connected to the end of the arc-shaped support frame 76 away from the rotating column 73.
[0037] The dispersing port 72 is provided in multiple sets and is staggered. The top of the processing spherical shell 71 is fixedly connected to the bottom of the support rod 6. The end of the support rod 6 near the processing spherical shell 71 passes through the processing cylinder 1 and is fixedly connected to the processing cylinder 1. The end of the fixing block 75 away from the electric rotating seat 74 is fixedly connected to the inner wall of the processing cylinder 1.
[0038] Two sets of rotating columns 73 are symmetrically distributed on both sides of the processing spherical shell 71. The arc-shaped extrusion plates 77 correspond one-to-one with the dispersing ports 72. The arc-shaped extrusion plates 77 are slidably connected to the inner wall of the dispersing ports 72. The arc-shaped extrusion plates 77 on both sides of the processing spherical shell 71 are staggered. One end of the feed frame 4 is connected to the processing spherical shell 71.
[0039] In use, the cellulose to be processed is poured into the processing shell 71 from the feed frame 4. Then, the cellulose entering the processing shell 71 is dried by the drying device 8. At the same time as the cellulose is dried, the electric rotating seat 74 is turned on, which drives the rotating column 73 to rotate. When the rotating column 73 rotates, it drives the arc support frame 76 to move. The arc support frame 76 drives the arc extrusion plate 77 to slide into the processing shell 71 from the dispersing port 72, and continuously taps the cellulose in the processing shell 71. Since the two sets of arc extrusion plates 77 are staggered, they can squeeze and disperse the cellulose that has clumped in the processing shell 71, preventing the cellulose from sticking together during drying.
[0040] For the second embodiment, please refer to... Figures 1-9 The present invention provides a technical solution: Based on the first embodiment, the drying device 8 includes an air pump 81, the air outlet end of the air pump 81 is connected to an air outlet pipe 82, the end of the air outlet pipe 82 away from the air pump 81 is connected to a heating frame 83, the end of the heating frame 83 away from the air outlet pipe 82 is connected to an arc-shaped exhaust pipe 84, the end of the arc-shaped exhaust pipe 84 away from the heating frame 83 is equipped with an adjustment device 85, and the bottom of the air pump 81 is fixedly connected to a connecting frame 86.
[0041] An electric heating wire is installed inside the heating frame 83. The end of the connecting frame 86 away from the air pump 81 is fixedly connected to the outer wall of the processing cylinder 1. The arc-shaped exhaust pipe 84 passes through the arc-shaped opening 9.
[0042] The adjusting device 85 includes a first rotating bolt 851 and a second rotating bolt 852. A first adjusting plate 853 is fixedly connected to the rotating part of the first rotating bolt 851, and a second adjusting plate 854 is fixedly connected to the fixed part of the first rotating bolt 851. A third adjusting plate 855 is fixedly connected to the rotating part of the second rotating bolt 852, and a fourth adjusting plate 856 is fixedly connected to the fixed part of the second rotating bolt 852. Sealing covers 857 are used between the first adjusting plate 853 and the third adjusting plate 855, and between the second adjusting plate 854 and the fourth adjusting plate 856. The ends of the first adjusting plate 853 and the second adjusting plate 854 furthest from the first rotating bolt 851 are respectively connected via… The rotating seat is rotatably connected to the first electric push rod 858 and the second electric push rod 859. One side of the second adjusting plate 854 and the fourth adjusting plate 856 are both connected to a connecting pipe 8510. One end of the connecting pipe 8510 is connected to an arc-shaped air outlet pipe 8512 through an elastic pipe 8511. An air inlet 8513 is opened on the outer side of the arc-shaped exhaust pipe 84. An arc-shaped push rod 8514 is connected to the third adjusting plate 855. The end of the arc-shaped push rod 8514 away from the third adjusting plate 855 is fixedly connected to a sealing plug 8515. The fixing parts of the first rotating bolt 851 and the second rotating bolt 852 are both fixedly connected to a drying frame 8516.
[0043] The sealing cover 857 is made of rubber. The end of the first electric push rod 858 away from the first adjusting plate 853 is fixedly connected to the outside of the heating frame 83. The end of the second electric push rod 859 away from the second adjusting plate 854 is fixedly connected to the outer wall of the processing cylinder 1. The end of the arc-shaped push rod 8514 near the sealing plug 8515 passes through the arc-shaped exhaust pipe 84 and is slidably connected to the arc-shaped exhaust pipe 84. The sealing plug 8515 is slidably connected to the inner wall of the arc-shaped exhaust pipe 84.
[0044] The end of the arc-shaped exhaust pipe 84 near the arc-shaped push rod 8514 passes through the first adjusting plate 853. The part of the arc-shaped exhaust pipe 84 located outside the first adjusting plate 853 is set as a flexible hose. The end of the arc-shaped exhaust pipe 8512 away from the elastic tube 8511 is connected to the processing spherical shell 71.
[0045] In use, the air pump 81 is turned on to draw outside air into the air outlet 82, and then the air is drawn into the heating frame 83 through the air outlet 82. The electric heating wire inside the heating frame 83 heats the passing gas. The heated gas is discharged from the arc-shaped exhaust pipe 84 through the regulating device 85 into the processing sphere shell 71 to dry the cellulose inside. At this time, the air pumping speed of the air pump 81 can be adjusted. When the air speed is faster, coarser and heavier cellulose can be blown from the dispersing port 72 into the processing cylinder 1. When the air speed is lower, only fine cellulose can be blown away. It is convenient to adjust the air speed according to the required specifications.
[0046] When the wind speed is high, the first electric push rod 858 and the second electric push rod 859 are activated, causing them to extend continuously. The first electric push rod 858 pushes the first adjusting plate 853 and the third adjusting plate 855, while the second electric push rod 859 pushes the second adjusting plate 854 and the fourth adjusting plate 856. This causes the first adjusting plate 853 to rotate around the first rotating bolt 851, and the third adjusting plate 855 to rotate around the second rotating bolt 852, continuously expanding the sealing cover 857. As a result, the space covered by the sealing cover 857 gradually increases, and the sealing cover 857 expands to a larger space. At this time, the amount of air that the sealing cover 857 can hold increases, so that even if the air in the sealing cover 857 is discharged faster, the air entering the sealing cover 857 still has enough time to fully contact the desiccant filled in the drying frame 8516.
[0047] When the first electric push rod 858 retracts, it pushes the first adjusting plate 853 and the third adjusting plate 855 to move. The third adjusting plate 855 drives the sealing plug 8515 through the arc-shaped push rod 8514 to gradually block the air inlet 8513, so that the air inlet 8513 can change with the wind speed of the air pump 81. The lower the wind speed, the smaller the ventilation diameter of the air inlet 8513. When the wind speed is zero, the air inlet 8513 is blocked and sealed by the sealing plug 8515. At this time, it can prevent external air from entering the drying frame 8516 and reacting with the desiccant when the device is not in use.
[0048] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
