Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire-retardant coating technology, specifically to an anti-sticking stirring device for the production of fire-retardant coatings. Background Technology
[0002] Fire-retardant coatings are special coatings applied to the surface of combustible substrates to reduce the flammability of the coated material, inhibit the rapid spread of fire, and improve the fire resistance limit of the coated material. They are applied to the surface of combustible substrates to change the combustion characteristics of the material surface and inhibit the rapid spread of fire, or applied to building components to improve the fire resistance limit of the components.
[0003] In the production process of fire-retardant coatings, it is necessary to mix a variety of different raw materials. However, existing mixing equipment is generally unidirectional rotating mixing, which can easily lead to the lumps in the raw materials not being broken up during use. Secondly, after the internal stirring equipment in the tank is used, some raw materials will stick to the surface of the stirring bar, resulting in waste and difficulty in cleaning later. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-sticking stirring device for the production of fireproof coatings. It solves the problems of existing mixing equipment, which generally rotates in one direction and mixes, which easily leads to the agglomeration of raw materials that cannot be broken up during use. In addition, after the stirring equipment inside the tank is used, some raw materials will stick to the surface of the stirring bar, causing waste and making it difficult to clean later.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-sticking stirring device for the production of fire-retardant coatings, comprising: a stirring tank and an extension cover, wherein the extension cover is located directly above the stirring tank, and a feeding port for feeding is provided in the middle of the top of the extension cover, the feeding port is fixedly connected to a conveying pipe, and the other end of the conveying pipe is fixedly connected to a conveying pump for transmission function.
[0006] A fixing ring is fixedly connected to the outside of the mixing tank, and several connecting frames are fixedly connected to the surface of the fixing ring. The top of each connecting frame is fixedly connected to the outside of the extension cover. A support leg for support is fixedly connected to the bottom of the mixing tank, and an installation support frame is fixedly connected inside the support leg.
[0007] The top of the support frame is fixedly connected to a transmission mechanism, and the top of the transmission mechanism extends into the interior of the mixing tank and is fixedly connected to an anti-stick stirring mechanism for stirring function.
[0008] Furthermore, the anti-stick stirring mechanism includes a stirring head, a drive bar, stirring strips, connecting strips, and cleaning plates. The stirring head has a frustum-shaped cross-section and a pointed top. Several drive bars are provided and are evenly fixedly connected to the outside of the stirring head. The stirring strips are fixedly connected to the outside of the drive bars in an array. Several connecting strips are provided and are inclined. The cleaning plates are fixedly connected to the inside of the connecting strips in an array.
[0009] Furthermore, the stirring bar is S-shaped, and the width and shape of the cleaning plate are adapted to the spacing and shape of two stirring bars located close to each other in the same vertical section.
[0010] Furthermore, a connecting ring is fixedly connected to the top end of the connecting strip, and an annular slide bar for rotatable connection is fixedly connected to the bottom end of the connecting ring. The connecting ring is located at the top of the mixing tank, and the annular slide bar is slidably connected to the top of the mixing tank.
[0011] Furthermore, the transmission mechanism includes a servo motor, sprockets, a chain, a drive shaft, a gear, and a gear ring. The sprockets are provided in two and are connected by the chain drive. One of the sprockets is fixedly connected to the output end of the servo motor, and the other is fixedly connected to the bottom end of the drive shaft. The gear is fixedly connected to the end of the drive shaft away from the sprockets, and the gear meshes with the gear ring.
[0012] Furthermore, the servo motor is fixedly connected to the bottom of the mixing tank, the output end of the servo motor passes through the mixing tank and is fixedly connected to the bottom of the mixing head, and the connection between the servo motor and the mixing tank is movably connected by a bearing.
[0013] Furthermore, the drive shaft passes through the fixed ring, and the connection between the drive shaft and the fixed ring is movably connected by a bearing. The toothed ring is fixedly connected to the top of the connecting ring, and an annular slide bar II is fixedly connected to the top surface of the toothed ring. The toothed ring is located directly below the extension cover, and the annular slide bar II is slidably connected to the bottom end of the extension cover.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model drives the stirring head to rotate clockwise, which in turn drives the stirring bar to rotate and mix the fire-retardant coating material inside. At the same time, it is driven by the connecting ring to rotate counterclockwise. When the cleaning plate and the stirring bar meet, the cleaning plate passes through the gap between the cleaning plates. This helps to prevent large lumps from getting stuck in the gap between the stirring bars and reducing the mixing effect. In addition, the stirring equipment is equipped with a cleaning function to prevent the fire-retardant coating material from remaining on the surface of the equipment.
[0016] 2. This utility model starts with a servo motor and drives the drive shaft through a sprocket and chain. The gear drives the gear ring to rotate. During this process, the rotation direction of the gear ring is opposite to that of the stirring head. The gear ring drives the fixed ring to rotate on the opposite side of the mixing tank and the extension cover through the annular slide bar one and annular slide bar two. This facilitates simultaneous forward and reverse rotation stirring, ensuring the uniformity of the fireproof coating raw materials. Furthermore, during the stirring process, the opposing stirring force of the stirring equipment effectively breaks up any lumps in the fireproof coating raw materials. Attached Figure Description

[0028] Example 2
[0029] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 The present invention preferably provides the following technical solution: the anti-stick stirring mechanism 11 includes a stirring head 1101, a drive bar 1102, a stirring bar 1103, a connecting bar 1104, and a cleaning plate 1105. The stirring head 1101 has a frustum-shaped cross section and a pointed top. Several drive bars 1102 are provided and are evenly fixedly connected to the outside of the stirring head 1101. The stirring bars 1103 are fixedly connected to the outside of the drive bars 1102 in an array. Several connecting bars 1104 are provided and are inclined. The cleaning plates 1105 are fixedly connected to the inside of the connecting bars 1104 in an array. The stirring bars 1103 are S-shaped. The width and shape of the cleaning plates 1105 are adapted to the spacing and shape of two stirring bars 1103 located on the same vertical cross section and close to each other.
[0030] By driving the stirring head 1101 to rotate clockwise, the stirring head 1101 drives the stirring bar 1103 to rotate via the driving bar 1102 to mix and stir the fire retardant coating material inside. At the same time, it is driven by the connecting ring 12 to rotate counterclockwise. As the cleaning plate 1105 and the stirring bar 1103 meet, the cleaning plate 1105 passes through the gap between the cleaning plates 1105. This helps to prevent large lumps from getting stuck in the gap between the stirring bars 1103 during stirring, thus reducing the stirring effect. In addition, the stirring equipment is equipped with a cleaning function to prevent the fire retardant coating material from remaining on the surface of the equipment.

[0033] Example 4
[0034] Please see Figure 1 , Figure 2 and Figure 4 The present invention preferably provides the following technical solution: The transmission mechanism 10 includes a servo motor 1001, a sprocket 1002, a chain 1003, a drive shaft 1004, a gear 1005, and a gear ring 1006. Two sprockets 1002 are provided and are connected by the chain 1003. One sprocket 1002 is fixedly connected to the output end of the servo motor 1001, and the other is fixedly connected to the bottom end of the drive shaft 1004. The gear 1005 is fixedly connected to the end of the drive shaft 1004 away from the sprocket 1002, and the gear 1005 meshes with the gear ring 1006. The servo motor 1001 is fixedly connected to the bottom end of the mixing tank 1. The output end of the servo motor 1001 passes through the mixing tank 1 and is fixedly connected to the bottom end of the stirring head 1101. The connection between the servo motor 1001 and the mixing tank 1 is movably connected by a bearing.
[0035] The servo motor 1001 starts the drive shaft 1004 through the sprocket 1002 and chain 1003, thereby driving the gear ring 1006 to rotate through the gear 1005. During this process, the rotation direction of the gear ring 1006 is opposite to that of the stirring head 1101. The gear ring 1006 drives the fixed ring 6 to rotate on the opposite side of the mixing tank 1 and the extension cover 2 through the annular slide bar 13 and the annular slide bar 2.

[0036] Example 5
[0037] Please refer to 3. The preferred technical solution provided by this utility model is as follows: the drive shaft 1004 passes through the fixed ring 6, and the connection between the drive shaft 1004 and the fixed ring 6 is movably connected by a bearing. The toothed ring 1006 is fixedly connected to the top of the connecting ring 12, and an annular slide bar 14 is fixedly connected to the top surface of the toothed ring 1006.

In use, the fire-retardant coating material is injected into the extension shroud 2 through the injection port 3 via the delivery pump 5 and the delivery pipe 4. The fire-retardant coating material then falls into the mixing tank 1 through the extension shroud 2. Simultaneously, the servo motor 1001 is started, driving the stirring head 1101 to rotate clockwise. The stirring head 1101, through the drive bar 1102, drives the stirring bar 1103 to rotate, mixing the fire-retardant coating material inside. The servo motor 1001 starts simultaneously... The drive shaft 1004 is driven by the sprocket 1002 and the chain 1003, which in turn drives the gear ring 1006 to rotate by the gear 1005. During this process, the rotation direction of the gear ring 1006 is opposite to that of the stirring head 1101. The gear ring 1006 drives the fixed ring 6 to rotate on the opposite side of the mixing tank 1 and the extension cover 2 through the annular slide bar 13 and the annular slide bar 2. At this time, it is driven by the connecting ring 12 to rotate counterclockwise. When the cleaning plate 1105 and the stirring bar 1103 meet, the cleaning plate 1105 passes through the gap between the cleaning plates 1105.
