Description

Technical Field

[0001] The utility model particularly relates to a high-efficiency foam eliminator for coatings. Background Art

[0002] During the production process of coatings, foam problems are likely to occur. If harmful foam is not processed in a timely manner, it will not only affect the production process, but more importantly, it will affect the use of the coatings, resulting in construction defects such as shrinkage holes and fisheyes. For example, in a defoaming device for coating production disclosed in the authorized publication number CN214634217U, during use, an appropriate amount of coating is poured into the box body. When defoaming is required, the output shaft of the electro-hydraulic push rod extends to drive the U-shaped frame to descend. When the limit slider slides to the bottom of the limit chute, at this time, the support shaft is located inside the box body, and part of the multiple cutting knives is located above the coating, and part is located inside the coating. At this time, the top of the contact block is just slightly lower than the top height of the box body. Then, the output shaft of the motor is rotated to drive the first pulley to rotate. The first pulley drives the second pulley to rotate through belt transmission. The second pulley drives the lead screw to rotate. The lead screw drives the moving block to move. The moving block moves and drives the support shaft to move together. Since the gear on the support shaft meshes with the toothed plate, the support shaft rotates, driving the multiple cutting knives to cut the bubbles. At the same time, the multiple stirring rods at the bottom and the multiple slices on them will stir and mix the coating more fully while the large number of generated bubbles are cut and stirred again. At the same time, some bubbles that are not cut by the slices will rise to the surface of the coating and are broken by the multiple cutting knives again. However, the following problems exist during the use process:

[0003] When the stirring rod is stirring, some bubbles will move to the inner side wall of the box body, and the rotation range of the support shaft driving the cutting knife is fixed. Therefore, it is difficult to eliminate the bubbles near the inner side wall of the box body. If the length of the cutting knife is designed to fit one end on the inner side wall, it will affect the rotation performance and may also scratch the inner side wall of the box body. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a high-efficiency foam eliminator for coatings.

[0023] A high-efficiency foam eliminator for coatings, referring to Figures 1 - 3 , includes an operation table 1, a box body 2 arranged on the operation table 1, and an operation chamber 3 arranged in the box body 2. A connecting rod 4 is connected to the top wall of the operation chamber 3. A cross 5 is arranged at the lower end of the connecting rod 4. A plurality of first stirring teeth 6 are arranged at the lower end of the cross 5. A first driving device 7 connected to the connecting rod 4 is arranged on the box body 2. A stirring frame is connected to the bottom of the operation chamber 3. Auxiliary rods 8 are respectively arranged on both sides of the stirring frame and are inclined upward. A second driving device for driving the stirring frame to rotate is arranged on the operation table 1.

[0024] Further, the stirring frame includes a rotating shaft 91, and cross bars 92 are symmetrically arranged on both sides of the rotating shaft 91. The auxiliary rod 8 is provided at one end of the cross bar 92 away from the rotating shaft 91.

[0025] Further, a plurality of second stirring teeth 921 are arranged along the circumferential side of the cross bar 92.

[0026] Further, the auxiliary rod 8 is detachably connected to the cross bar 92.

[0027] Further, an installation groove 11 is formed on the cross bar 92, and a locking member 12 adapted to the cross bar 92 is arranged on the installation groove 11. One end of the cross bar 92 is inserted into the installation groove 11, and the locking member 12 is used to connect the cross bar 92 and the auxiliary rod 8.

[0028] Further, positioning grooves 81 are symmetrically arranged along the circumferential direction at the end of the auxiliary rod 8, and positioning blocks 111 corresponding to the positioning grooves 81 are arranged in the installation groove 11. The positioning groove 81 defines a first end 811 and a second end 812. When one end of the auxiliary rod 8 is inserted into the installation groove 11 and the positioning block 111 moves from the first end 811 to the second end 812, one end of the locking member 12 can pass through the cross bar 92 and extend into the installation groove 11 to connect the auxiliary rod 8.

[0029] The working principle of the present utility model is:

[0030] When in use, the raw material components of the coating formula are put into the operation chamber 3, and the second driving device is started. The second driving device drives the stirring frame to rotate. When the stirring frame rotates, all the raw material components are evenly stirred; during the preliminary stirring and dissolving process, a small amount of bubbles will appear in the liquid. In this application, the stirring frame is set as the rotating shaft 91, and cross bars 92 are symmetrically arranged on both sides of the rotating shaft 91. Second stirring teeth 921 are arranged on the circumferential side of the cross bar 92. At this time, the second stirring teeth 921 have the effect of defoaming the bubbles located within the liquid level of the liquid; as the stirring continues, the bubbles will increase. At this time, some bubbles will move to the liquid surface. When bubbles are observed on the liquid surface, the first driving device 7 is started. Since the first driving device 7 is connected to the cross 5 through the connecting rod 4, and a plurality of first stirring teeth 6 are arranged at the lower end of the cross 5, the first driving device 7 drives the cross 5 to rotate, thereby driving the first stirring teeth 6 to rotate to defoam the bubbles on the liquid surface; during the rotation of the cross 5, the bubbles on the inner side wall of the box body 2 can be rotated and brought into the position 1-1 near the center of the liquid level. Through experiments, it is proved that there will still be some bubbles staying on the inner side wall of the box body 2. Therefore, in this application, auxiliary rods 8 are respectively arranged on both sides of the stirring frame. When the rotation speed of the second driving device is relatively high (the rotation speed is 100 - 800 revolutions per minute), when the auxiliary rods 8 and the cross 5 rotate simultaneously, at this time, smaller vortex shapes will be formed on the liquid surface. Therefore, the bubbles on the inner side wall of the box body 2 can be rotated and brought into the position 1-1 near the center of the liquid level; at this time, the first stirring teeth 6 on the cross 5 defoam the bubbles. In the prior art, to form a vortex shape on the liquid surface, the rotating shaft 91 needs to be adjusted to a high-speed rotating state (the rotation speed is 2000 - 8000 revolutions per minute). However, high-speed rotation will cause more bubbles to be generated in the coating, which instead increases the difficulty of defoaming in the later stage. As an embodiment, both the above-mentioned first driving device 7 and the second driving device can be selected as rotary motors to achieve.

[0031] On the basis of the above technical solution, considering the use scenario of the box body 2, because some box bodies 2 are only used for cooling or pre-treatment of solvents in the early stage, and the above process does not require defoaming. That is to say, the existence of the auxiliary rods 8 may adhere to the raw material components, causing waste of raw materials and increasing the cleaning work; in this application, the auxiliary rods 8 are set to be detachably connected to the cross bars 92. As Embodiment 1, installation grooves 11 are opened on the cross bars 92, and positioning blocks 111 are symmetrically arranged in the installation grooves 11. When one end of the auxiliary rod 8 is inserted into the installation groove 11, the positioning blocks 111 will move from the first end 811 of the positioning groove 81 to the second end 812. When moving to the second end 812, one end of the locking member 12 passes through the cross bar 92 and extends into the installation groove 11 to lock the auxiliary rod 8, thereby realizing the connection and fixation between the auxiliary rod 8 and the cross bar 92. The locking member 12 can be selected as a screw to achieve.

[0032] In view of the situation that it is difficult to eliminate the bubbles on the inner side wall of the existing box body 2, through the cooperation of structures such as the auxiliary rod 8, the cross 5, the first stirring teeth 6, etc., the bubbles are brought to a position close to the center of the liquid surface, so that the first stirring teeth 6 can eliminate the bubbles, improving the working efficiency.

[0033] Although the present utility model has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made to the present utility model without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of this disclosure is only used to explain, rather than to limit the present utility model, and the scope of protection is defined by the content of the claims.
