Description

Technical Field

[0001] This application belongs to the technical field of fire-retardant coating production equipment, specifically a fire-retardant coating disperser. Background Technology

[0002] A disperser is a specialized piece of equipment used in the production of fire-retardant coatings. The disperser has a circular dispersing disc with upper and lower serrations on its outer circumference. The high-speed rotation of the dispersing disc can shear, impact, crush, and disperse materials, enabling slurries of different viscosities to be dispersed, emulsified, and mixed.

[0003] The raw material for fire-retardant coatings is a liquid slurry, typically stored in cylindrical containers. Due to the slurry's viscosity, even with high-speed rotation of the dispersing disc, the agitation effect on the slurry at the edges is poor. Furthermore, for equipment safety, the relative positions of the container and the stirring shaft remain constant during disperser operation. This results in poor actual agitation and dispersion of the slurry at the edges, requiring the disperser to run for an extended period to achieve the desired effect. Utility Model Content

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] Please refer to the following: Figures 1 to 7 The fire-retardant coating disperser provided in the embodiments of this application will be described below.

[0024] The fire-retardant coating disperser provided in this application includes a slurry tank 10, a column 20, a stirring assembly 30, and a scraping assembly 40. The slurry tank 10 has a receiving cavity for storing the slurry, with an opening at the top. The column 20 is vertically disposed on one side of the slurry tank 10, and a cantilever 21 is provided at the top of the column 20, with one end of the cantilever 21 extending horizontally above the slurry tank 10. The stirring assembly 30 includes a stirring mechanism 31 and a stirring drive mechanism 32. The stirring mechanism 31 is disposed on the cantilever 21 and extends downward into the receiving cavity. The stirring drive mechanism 32 drives the stirring mechanism 31 to rotate around a vertical axis. The line is eccentrically positioned relative to the central axis of the receiving cavity; the scraping assembly 40 includes a scraping mechanism 41 and a scraping drive mechanism 42. The scraping mechanism 41 is located on the cantilever 21 and extends downward into the receiving cavity. The scraping mechanism 41 has a first scraping element 417 for abutting against the side wall of the receiving cavity and a second scraping element 418 for abutting against the bottom wall of the receiving cavity. The scraping drive mechanism 42 is used to drive the scraping mechanism 41 to rotate about a vertical axis, and the rotation axis of the scraping mechanism 41 coincides with the central axis of the receiving cavity.

[0025] Compared with the prior art, the beneficial effects of the fire-retardant coating disperser provided in this application embodiment are: The fire-retardant coating disperser provided in this embodiment includes a slurry tank 10, a column 20, a stirring assembly 30, and a scraping assembly 40. The slurry tank 10 stores the slurry. The stirring assembly 30 and the scraping assembly 40 are respectively mounted on the cantilever 21 of the column 20. When the stirring assembly 30 operates, it uses a stirring mechanism 31 to stir the slurry at high speed for dispersion and emulsification. When the scraping assembly 40 operates, the first scraper 417 of the scraping mechanism 41 can scrape off the slurry adhering to the side wall of the receiving cavity, and the second scraper 418 can scrape off the slurry adhering to the bottom wall of the receiving cavity. This arrangement can improve the flowability of the slurry at the edges. The scraping mechanism 41 is coaxially arranged with the receiving cavity, while the stirring mechanism 31 is eccentrically arranged with the receiving cavity. The two operate independently and will not cause motion interference. The scraping mechanism 41 and the stirring mechanism 31 work together to help shorten the operating time of the disperser and improve the dispersion efficiency of the slurry.

[0026] The slurry tank 10 is used to store slurry. The slurry tank 10 is usually cylindrical and can be made of materials such as stainless steel. The slurry tank 10 can be fixed in place or moved around during use.

[0027] When the slurry tank 10 is fixedly installed, a discharge valve 12 can be installed at the bottom of the slurry tank 10 to control the discharge of slurry.

[0028] When the slurry tank 10 needs to be moved, casters can be installed at the bottom of the slurry tank 10, and a clamping mechanism for detachable connection to the slurry tank 10 can be installed on the column 20. The clamping mechanism is used to clamp and fix the slurry tank 10 when the disperser is working, preventing the slurry tank 10 from moving during the operation of the disperser. After the work is completed, the clamping mechanism is released, and the slurry tank 10 can be pushed to the designated position.

[0029] The column 20 is used to support the mixing assembly 30 and the scraping assembly 40. The column 20 can be a fixed metal column or a liftable column. When a liftable structure is used, the column 20 is usually powered by a hydraulic pump and a hydraulic cylinder. Using hydraulic cylinders for lifting the column 20 is a common drive method in the mechanical field. Its specific installation and usage will not be described in detail, but those skilled in the art should be able to understand and implement it.

[0030] The mixing assembly 30 includes a mixing mechanism 31 and a mixing drive mechanism 32. The mixing mechanism 31 can be a commercially available dispersing machine mixing mechanism 31, such as a dispersing disc 312.

[0031] Please see Figure 1 and Figure 4 The stirring mechanism 31 includes a first rotating shaft 311 and a dispersing disc 312. The first rotating shaft 311 is a metal shaft, located at one end of the cantilever 21 above the slurry tank 10, and is rotatably connected to the cantilever 21 through bearings and other fitting parts. The first rotating shaft 311 extends vertically downward into the receiving cavity, and the stirring drive mechanism 32 is connected to the first rotating shaft 311 for transmission. The dispersing disc 312 is coaxially located at the bottom of the first rotating shaft 311. The outer edge of the dispersing disc 312 is provided with a plurality of first dispersing teeth and second dispersing teeth, which are alternately arranged. The first dispersing teeth extend upward and the second dispersing teeth extend downward.

[0032] Please see Figures 1 to 3 ,as well as Figure 7 The stirring drive mechanism 32 includes a first motor 321 and a first transmission component 322. The first motor 321 is located at the end of the cantilever 21 away from the slurry tank 10; the first transmission component 322 is connected to the output shaft of the first motor 321 and the first rotating shaft 311.

[0033] The first motor 321 drives the first rotating shaft 311 and the dispersing disk 312 to rotate at high speed via the first transmission component 322. In order to improve the disturbance effect of the dispersing disk 312 on the slurry, the dispersing disk 312 includes first and second dispersing teeth arranged alternately. There are no specific restrictions on the diameter, rotation speed and other parameters of the dispersing disk 312, and the user can choose and set them according to the actual situation.

[0034] The first transmission component 322 is used to transmit the power output from the first motor 321 to the first rotating shaft 311. The first transmission component 322 can be a common transmission form such as gear transmission, chain transmission, or belt transmission. It should be noted that when using chain transmission or belt transmission, necessary tensioning pulleys and other components should be provided to adjust the tension of the transmission structure and prevent slippage and other problems.

[0035] The scraping assembly 40 includes a scraping mechanism 41 and a scraping drive mechanism 42. The scraping mechanism 41 has a first scraper 417 and a second scraper 418. When the first scraper 417 rotates, it can fit against the side wall of the receiving cavity and scrape off the material adhering to the side wall of the receiving cavity. When the second scraper 418 rotates, it can fit against the bottom wall of the receiving cavity and scrape off the material adhering to the bottom wall of the receiving cavity. The scraping mechanism 41 rotates at a relatively slow speed, which can also play a role in low-speed stirring, promoting the thorough mixing of slurry located in different positions and improving the efficiency of the disperser.

[0036] It should be noted that the scraping mechanism 41 and the stirring mechanism 31 operate independently and do not interfere with each other. The first scraper 417 and the second scraper 418 should not collide or interfere with the dispersing disc 312 during rotation. The rotation directions of the scraping mechanism 41 and the stirring mechanism 31 can be the same or different. The rotational speed of the scraping mechanism 41 is usually lower than that of the stirring mechanism 31; there are no restrictions on the specific rotational parameters, and users can set them according to their actual needs.

[0037] The scraping drive mechanism 42 can be configured in the same way as the stirring drive mechanism 32, and will not be described in detail here.

[0038] Please see Figure 1 , Figure 3 and Figure 7 In some possible embodiments, the cantilever 21 is a hollow component with an internal mounting cavity. The scraping drive mechanism 42, the first transmission component 322, and the output shaft of the first motor 321 are respectively housed within the mounting cavity. The mounting cavity has a maintenance port with a maintenance cover. During normal use, the mounting cavity is closed to prevent external dust and other contaminants from affecting the operation of the transmission system. When maintenance or repair is required, the maintenance cover can be removed to open the mounting cavity.

[0039] To improve the safety of using the device, please refer to Figure 2 , Figure 3 and Figure 7In some possible embodiments, two sets of guide rails 11 are arranged opposite each other on the upper part of the slurry tank 10. One end of the guide rail 11 is connected to the slurry tank 10, and the other end extends horizontally away from the slurry tank 10. The fire retardant coating disperser also includes a protective cover plate 50. There are two protective cover plates 50, which are arranged opposite each other. A connecting plate is provided on the side of the two protective cover plates 50 that are opposite each other. The two protective cover plates 50 are slidably engaged with the two guide rails 11. A first clearance notch 51 for the stirring mechanism 31 to pass through is opened on the side of the opposite of one protective cover plate 50, and a second clearance notch 52 for the scraping mechanism 41 to pass through is opened on the side of the opposite of the other protective cover plate 50.

[0040] In this embodiment, the protective cover 50 serves to prevent objects from entering the receiving cavity during the operation of the disperser. The protective cover 50 can be a solid metal plate or a protective mesh, as long as it provides an isolation function. When a solid plate is used, it can prevent slurry from splashing to the outside. When a protective mesh is used, the operator can see the inside of the receiving cavity through the mesh.

[0041] like Figure 3 and Figure 7 As shown, two protective covers 50 are provided, and the two protective covers 50 are slidably fitted onto two guide rails 11 respectively. The two protective covers 50 can be aligned to form a circle. The two protective covers 50 can have the same shape and size or different shapes.

[0042] Considering that both the first rotating shaft 311 and the second rotating shaft 411 (described below) need to pass through the protective cover plate 50, the two protective cover plates 50 are respectively provided with a first clearance notch 51 and a second clearance notch 52. Connecting plates are respectively provided on the adjacent sides of the two protective cover plates 50, allowing them to be connected and fixed during the operation of the disperser. The two protective cover plates 50 can only be separated after the disperser is stopped. The connecting plates can be detachable using magnetic fixing, bolt connection, or other detachable connection methods.

[0043] To facilitate real-time observation of the material inside the slurry tank 10 by operators, at least one protective cover 50 is provided with an observation window, through which the flow of the internal material, the degree of slurry mixing and dispersion, and the liquid level can be observed.

[0044] The observation window can be open, or it can be covered with transparent glass to prevent objects from falling in, as long as it allows outsiders to see the inside of the slurry tank 10.

[0045] Specifically, such as Figure 3As shown, the two protective covers 50 are of different sizes. One protective cover 50 is larger and the other is smaller. The smaller protective cover 50 is made of metal mesh, and the operator can see the inside of the receiving cavity through the metal mesh.

[0046] For instructions on adding slurry into the cavity, please refer to [link / reference]. Figure 3 and Figure 7 At least one protective cover plate 50 has a feeding port, which is connected to a feeding pipe 53, and the feeding pipe 53 is connected to the slurry conveying mechanism.

[0047] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 In some possible embodiments, the scraping mechanism 41 further includes a second rotating shaft 411 and a support rod 412. The second rotating shaft 411 is located at one end of the cantilever 21 above the slurry tank 10 and is rotatably engaged with the cantilever 21. The second rotating shaft 411 extends vertically downward into the receiving cavity and is coaxially arranged with the receiving cavity. The scraping drive mechanism 42 is connected to the second rotating shaft 411 in a transmission manner. At least two support rods 412 are respectively arranged in the receiving cavity along the radial and axial directions and are connected to the second rotating shaft 411. The second scraper 418 is arranged on the support rod 412 extending radially along the receiving cavity, and the first scraper 417 is arranged on the support rod 412 extending axially along the receiving cavity.

[0048] The first scraper 417 and the second scraper 418 can be metal or plastic parts, and can be fixed to the corresponding support rod 412 by welding, snap-fitting, bolting or other methods, as long as they can achieve the scraping function.

[0049] Please see Figures 4 to 6 The support rod 412 has two mounting plates 413 spaced apart along its length, and the two mounting plates 413 form a clamping space for accommodating the corresponding first scraper 417 or second scraper 418. The mounting plate 413 has a first mounting hole and a limiting hole that penetrate its own thickness. Each mounting plate 413 has at least two limiting holes, which are respectively located on both sides of the corresponding first scraper 417 or second scraper 418.

[0050] Considering that the first scraper 417 and the second scraper 418 may wear out and may need to be replaced after a period of use, this embodiment designs the first scraper 417 and the second scraper 418 to be detachable. Specifically, the first scraper 417 and the second scraper 418 each have a second mounting hole that coaxially communicates with the first mounting hole. The scraping mechanism 41 also includes a connecting rod 414 and an anti-rotation rod 416. The connecting rod 414 corresponds one-to-one with the support rod 412. The connecting rod 414 passes through the first mounting hole and the second mounting hole, and each end is threaded with a locking nut 415. The locking nut 415 abuts against the opposite side of the two mounting plates 413. Multiple anti-rotation rods 416 are respectively passed through the corresponding limiting holes. The anti-rotation rods 416 are used to limit the rotation of the first scraper 417 or the second scraper 418. After tightening the locking nut 415, the anti-rotation rod 416 is inserted into the limiting hole, which can prevent the first scraper 417 or the second scraper 418 from rotating.

[0051] The anti-rotation rod 416 can be connected to the limiting hole in a detachable manner, such as by a threaded connection. The anti-rotation rod 416 has external threads, and the limiting hole has internal threads. When replacement is required, first remove the anti-rotation rod 416, unscrew the locking nuts 415 at both ends of the connecting rod 414, pull out the connecting rod 414, and replace it with a new first scraper 417 or a new second scraper 418.

[0052] Multiple support rods 412 extending radially along the cavity are spaced apart along the circumference of the cavity. When the length of the second scraper 418 is short, the multiple second scrapers 418 correspond to different positions on the bottom wall of the cavity. Similarly, multiple support rods 412 extending axially along the cavity are spaced apart along the circumference of the cavity. When the length of the first scraper 417 is short, the multiple first scrapers 417 correspond to different height positions on the side wall of the cavity.

[0053] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
