[0002] Polyurea is a high-performance elastomeric material with fast curing, high strength, and high flexibility. It is widely used in waterproofing, anti-corrosion and other fields. During the construction process, in order to ensure the quality of polyurea coating, correct mixing (commonly known as "stirring") is a very critical step.

[0003] Polyurea is usually composed of two components: component A (isocyanate component) and component B (amino compound component). These two components need to be mixed in a specific ratio before spraying.

[0004] Currently, polyurea is generally mixed by mixing the two materials in a mixing tank. After the polyurea is mixed and stirred, the mixing tank needs to be tilted before it can be poured out, which makes it difficult to control the amount of polyurea poured out. In addition, the stirring capacity of the existing mixing tank is insufficient, resulting in a long stirring time for the polyurea mixture.

[0005] Therefore, we need to design a mixing equipment for polyurea production with a fast discharging function to solve these problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] Example 1: Figures 1-4 As shown, a mixing device for polyurea production with a rapid discharging function includes a frame 1, a tank body 4 is rotatably arranged on the frame 1, a positioning plate 6 is provided on one side of the tank body 4, a plurality of positioning holes 9 are provided on the positioning plate 6, a fixing frame 7 is provided on the frame 1 on one side of the positioning plate 6, a positioning pin 8 is penetrated by the fixing frame 7, and the positioning pin 8 matches the positioning hole 9, and a discharging nozzle 11 and a stirring mechanism 5 are also provided on the tank body 4, and the discharging nozzle 11 is communicated with the interior of the tank body 4.

[0030] The stirring mechanism 5 can be detachably mounted on the tank body 4. The stirring mechanism 5 includes a transmission box 53, a drive assembly 51, a transmission assembly and a stirring assembly 52. The drive assembly 51 is fixedly arranged on the transmission box 53, and the stirring assembly 52 is rotatably arranged on the transmission box 53. The transmission assembly is located in the transmission box 53 and is respectively connected to the drive assembly 51 and the stirring assembly 52.

[0031] The transmission box 53 includes a detachably connected box body 502 and a box bottom 501; the driving assembly 51 includes a reducer 507 and a stirring motor 506, the reducer 507 is fixedly set on the box body 502, and the output end of the reducer 507 extends into the box body 502 and is connected to the transmission assembly, the stirring motor 506 is fixedly set on the reducer 507, and the output end is connected to the input end of the reducer 507; the stirring assembly 52 includes a stirring shaft 508, a stirring frame 509 and a cross bar 510, the stirring shaft 508 rotates and is set on the box bottom 501, there are two cross bars 510, and they are respectively fixed on the stirring shaft 508 on one side of the box body 502, the stirring frame 509 is fixed between the two cross bars 510, and the stirring shaft 508 on the other side of the box bottom 501 is connected to the transmission assembly.

[0032] The stirring frame 509 includes two mounting plates 5091 arranged parallel to each other, and a plurality of paddles 5092 are evenly arranged between the two mounting plates 5091. The paddles 5092 are arranged along the axis of the stirring shaft 508, and the angle between the paddles 5092 and the axis of the stirring shaft 508 is not a right angle. The inclined paddles 5092 will drive the flow of the polyurea raw material in the tank body 4 when rotating, which can improve the mixing efficiency.

[0033] A reinforcement rod 512 is also provided between the two cross bars 510. One end of the reinforcement rod 512 is connected to the connection of the rotating shaft 3 of one of the cross bars 510, and the other end of the reinforcement rod 512 is connected to the connection between the other cross bar 510 and the stirring frame 509. The reinforcement rod 512 cooperates with the stirring frame 509 and the stirring shaft 508 to form two triangles between the two cross bars 510. The triangle is stable, so the cross bars 510 and the stirring frame 509 can be reinforced.

[0034] The transmission assembly includes a first coupling 505 and a second coupling 513. The first coupling 505 is connected to the drive mechanism, and the second coupling 513 is connected to the stirring assembly 52. The first coupling 505 and the second coupling 513 match. This arrangement can achieve a direct connection between the reducer 507 and the stirring shaft 508 when there is only one stirring assembly 52.

[0035] The transmission assembly also includes a driving gear 503 and several driven gears 504. The driving gear 503 and several driven gears 504 are all rotatably set on the bottom 501 of the box, and several driven gears 504 are engaged with the driving gear 503. A stirring assembly 52 is fixedly set on each driven gear 504, and adjacent stirring assemblies 52 need to be set at a specific angle. For example, when there are two stirring assemblies 52, the installation positions need to be ninety degrees apart, and when there are three stirring assemblies 52, the angles need to be sixty degrees apart. This ensures that they will interweave with each other during rotation, and the length of the cross bar 510 shall not exceed the distance between two adjacent stirring bars, so as to avoid collision during rotation. Several stirring assemblies 52 are also rotatably connected by a stabilizing bar 511. Connecting multiple stirring shafts 508 through the stabilizing bar 511 can improve the stability of the stirring shaft 508 when driving the stirring frame 509 to rotate.

[0036] A connecting seat 2 is fixedly provided on the frame 1, a rotating shaft 3 is fixedly provided on the tank body 4, the free end of the rotating shaft 3 is driven and inserted into the connecting seat 2, a ball bearing is provided on the connecting seat 2, and the rotating shaft 3 is inserted into the ball bearing and connected to the connecting seat 2, which can reduce friction during rotation.

[0037] A handle 10 is fixedly provided at the free end of one of the rotating shafts 3 after passing through the connecting seat 2. The positioning plate 6 is fixed on the rotating shaft 3 on which the handle 10 is installed. The handle 10 can make it easier to rotate the tank body 4. The position of the tank body 4 after rotation can be fixed by the mutual cooperation between the positioning pin 8 and the positioning hole 9 on the positioning plate 6.

[0038] The working process of this embodiment: First ensure that the tank body 4 is in the following Figure 1 The tank body 4 is in the vertical state shown, and then the pins on the fixing frame 7 are inserted into the corresponding positioning holes 9 on the positioning plate 6. Then the stirring mechanism 5 is removed from the tank body 4, and the raw materials required for mixing polyurea are poured into the tank. Then, the stirring mechanism 5 is covered back on the tank body 4. It is necessary to ensure the sealing of the stirring mechanism 5 after the cover is closed to prevent the raw materials from flowing out from the joint between the stirring mechanism 5 and the tank body 4.

[0039] Then, the stirring motor 506 is started. After the stirring motor 506 is started, it drives the stirring component 52 to rotate through the transmission component.

[0040] After the stirring motor 506 rotates, it drives the reducer 507 to rotate. At this time, if there is only one transmission assembly on the transmission box 53, the output end of the reducer 507 is directly connected to the stirring shaft 508 of the stirring assembly 52 through the transmission shaft. The reducer 507 directly drives the stirring shaft 508 to rotate through the transmission shaft. After the stirring shaft 508 rotates, it drives the two cross bars 510 to rotate. The two stirring frames 509 installed between the two cross bars 510 will rotate around the stirring shaft 508 under the drive of the cross bars 510, thereby stirring and mixing the polyurea raw materials in the tank body 4; if the transmission assembly also includes a gear set consisting of a driving gear 503 and a driven gear 504, the reducer 507 is connected to the driving gear 503 through the transmission shaft. After the driving gear 503 rotates, it drives all meshing driven gears 504 to rotate. After the driven gears 504 rotate, they respectively drive the connected stirring assemblies 52 to rotate, thereby stirring the polyurea raw materials in the tank body 4 in all directions.

[0041] At the same time, in order to improve the stirring efficiency, the tank body 4 can be rotated by the handle 10 after it has been in a vertical state for a period of time. Before rotating the tank body 4 by the handle 10, it is necessary to first remove the positioning pin 8 on the fixing frame 7 that is inserted into the positioning hole 9 on the positioning plate 6. After the tank body 4 is rotated ninety degrees by the handle 10, the tank body 4 will become as shown in the figure. Figure 2 In the state shown, the discharge nozzle 11 is located above the tank body 4, and then the position of the tank body 4 at this time is positioned again through the positioning pin 8 on the fixing frame 7 and the positioning hole 9 on the positioning plate 6. By repeatedly rotating the tank body 4 and cooperating with the stirring assembly 52, the polyurea in the tank body 4 can be stirred more quickly.

[0042] After the polyurea is stirred, the power supply of the stirring motor 506 is cut off to stop the stirring motor 506. After the stirring motor 506 stops rotating, the reducer 507 and the stirring shaft 508 will stop rotating, and the stirring frame 509 will also stop rotating. Then, the positioning pin 8 is pulled out from the positioning hole 9 on the positioning plate 6 again, and then the tank body 4 is rotated by the handle 10 to slowly move the tank body 4 to the position shown in FIG. Figure 3 The tank body 4 rotates in the state shown. During the rotation, the polyurea in the tank body 4 will be poured out from the discharge nozzle 11, and the pouring speed and amount of the polyurea can be easily controlled by the handle 10.

[0043] The above describes an embodiment of the present invention in detail. However, the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
