Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating production technology, specifically to a raw material proportioning device for the production of fireproof coatings for steel structures. Background Technology
[0002] Fire-retardant coatings for steel structures are coatings that, when applied to the surface of steel structures, can improve the fire resistance of the steel, slow down the spread of flames, or prevent combustion for a certain period of time. Fire-retardant coatings are composed of a variety of different raw materials, and the different proportions of these raw materials will affect the fire-retardant performance of the coating. Therefore, it is necessary to use a mixing device to mix and proportion the various raw materials used in the production of fire-retardant coatings.
[0003] Existing raw material proportioning devices for steel structure fireproof coating production mostly weigh and proportion the raw materials, then directly pour them into the mixing tank and continuously stir to achieve a mixing effect. During the material mixing process, some powdery raw materials absorb water too quickly in certain areas, forming an adhesive film on the outside that hinders water penetration into the interior, causing the internal dry powder to clump together. This can have a certain impact on the quality of the coating, potentially requiring secondary mixing, increasing the proportioning time, and reducing processing efficiency. Optimization and improvement are needed. Utility Model Content

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0024] like Figure 1 - Figure 4 As shown, this application provides a raw material proportioning device for the production of fireproof coatings for steel structures, including: a mixing tank 1, a support leg 2 at the bottom of the mixing tank 1, and a feeding box 3 on the outside of the mixing tank 1;
[0025] Specifically, such as Figure 1 As shown, a telescopic cylinder 6 is provided on the inner side of the feeding box 3, and a sealing baffle 7 is connected to the inner side of the telescopic cylinder 6. The sealing baffle 7 is sealed to the side wall of the configuration barrel 1, and the position of the sealing baffle 7 is controlled by the telescopic cylinder 6.
[0026] The feeding adjustment assembly includes a cross support frame 8, which is located at the top of the configuration tank 1. A feeding box 5 is located at the top of the cross support frame 8, and a guide plate 11 is located inside the feeding box 5. The feeding adjustment assembly is used to adjust the feeding amount.
[0027] Specifically, such as Figure 2 As shown, the top of the cross support frame 8 is rotatably connected to the feed turntable 4, and the feed box 5 is installed on the top of the feed turntable 4. Multiple feed boxes 5 are provided to store different powdered raw materials required for coating mixing. The feed turntable 4 drives the feed box 5 to rotate at a uniform speed, and the feeding position of the feed box 5 is also continuously adjusted to make the material fall into the preparation bucket 1 more evenly.
[0028] Specifically, such as Figure 3As shown, the bottom end of the feed plate 4 is connected to the discharge pipe 10, and the guide plate 11 is rotatably connected to the bottom end of the discharge pipe 10. The inner side of the guide plate 11 is connected to the plug 13, and one side of the guide plate 11 is connected to the elastic connector 12. The guide plate 11 and the discharge pipe 10 are rotatably connected. The discharge pipe 10 is elastically squeezed by the elastic connector 12. After the guide plate 11 contacts the cross support frame 8, it can be rotated and adjusted so that the plug 13 on the inner side of the guide plate 11 fits against the bottom of the discharge pipe 10 to seal it. At this time, the discharge pipe 10 stops discharging material, achieving the effect of intermittently controlling the falling of material.
[0029] Specifically, such as Figure 3 As shown, a funnel groove 9 is provided on the inner side of the feed box 5. The shape of the funnel allows the material to fall slowly.
[0030] The bonding and scraping assembly includes a stirring blade 15, which is disposed at the inner bottom of the configuration tank 1. A connecting rod 16 is disposed on the outer side of the stirring blade 15, and a side scraper 20 is disposed on the outer side of the connecting rod 16. The bonding and scraping assembly is used for adjusting the bonding between the side scraper 20 and the inner wall of the configuration tank 1.
[0031] Specifically, such as Figure 2 As shown, a motor 14 is installed at the bottom center of the configuration tank 1. The motor 14 is used to adjust the rotation of the stirring blade 15 and to agitate and mix the internal coating.
[0032] Specifically, such as Figure 4 As shown, a rotating block 17 is rotatably connected to the outer side of the connecting rod 16, and a limiting block 18 is connected to the outer side of the rotating block 17. An elastic connector 21 is connected to the inner side of the connecting rod 16. The connecting rod 16 and the rotating block 17 are rotatably connected. The limiting block 18 restricts the rotation position of the connecting rod 16. The inner side is elastically connected through the elastic connector 21, which has a certain rotation limiting function.
[0033] Specifically, such as Figure 4 As shown, an elastic guide rod 19 is connected to the inner side of the rotating block 17, and a side scraper 20 is connected to the outer side of the elastic guide rod 19. The elastic guide rod 19 extends and retracts inside the rotating block 17 to control the position of the side scraper 20. The elastic force will cause the side scraper 20 to press against the side wall of the configuration barrel 1.
[0034] In this embodiment: a cross support frame 8 and a rotatable feed box 5 are provided at the top of the configuration tank 1, so that the material can be rotated and filled after storage. The guide plate 11 at the bottom will intermittently block the feed pipe 10 after being squeezed, so that the material is filled more evenly. During the mixing and stirring of the coating, the mixing is carried out by the rotation of the stirring blade 15. Then, the side scraper 20 is always in close contact with the side wall of the configuration tank 1 under the connection and adjustment of rotation and extension, which facilitates the full cleaning and transfer of the material.
[0035] The specific steps of this solution are as follows: When processing the raw materials for the production of fireproof coatings for steel structures, the different raw materials required for the proportioning are first weighed and placed inside the feeding box 5. Then, liquid raw materials are poured into the preparation tank 1. At this time, the motor 14 is started, driving the stirring blade 15 to rotate and stir. Then, the raw material at the top flows from the funnel trough 9 into the discharge pipe 10 and falls into the preparation tank 1. Because the guide plate 11 and the discharge pipe 10 are rotatably connected, the discharge pipe 10 is elastically squeezed through the elastic connector 12. After contacting the cross support frame 8, it can be rotated and adjusted to prevent blockage. The head 13 is attached to the bottom of the feed pipe 10 to seal it, controlling the flow rate of the material falling inside the feed box 5, allowing the raw material to be added to the liquid to achieve a uniform mixing effect. Then, the elastic guide rod 19 extends and retracts inside the rotating block 17 to control the position of the side scraper 20. The elastic force will drive the side scraper 20 to press against the side wall of the preparation tank 1, and the rotating block 17 and the connecting rod 16 are connected to a rotation limit, so that the side scraper 20 is tightly attached to the side wall of the preparation tank 1. After mixing, the telescopic cylinder 6 drives the sealing baffle 7 to move, allowing the paint inside the preparation tank 1 to flow out and be collected from the feed box 3.
[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
