Description

Technical Field

[0001] The present application relates to the technical field of preparing acrylate composite emulsions, and in particular to a defoaming device for preparing acrylate composite emulsions. Background Art

[0002] Acrylate emulsion is an important chemical raw material, characterized by its readily available raw materials, simple processing, long shelf life, ease of use, and strong bonding. It is widely used in adhesives, coatings, plastics, textiles, and other fields. Acrylate emulsions exhibit particularly excellent performance in the composite bonding of paper and plastics. However, during the processing of acrylic emulsions, various factors can cause the formation of numerous bubbles within the emulsion. If these bubbles are not removed promptly, they can seriously affect the quality and performance of the emulsion.

[0003] An existing patent (publication number: CN220003052U) discloses a defoaming device for preparing a water-based acrylic emulsion, which relates to the technical field of emulsion preparation. The defoaming device for preparing a water-based acrylic emulsion comprises a mixing box, a mixing assembly, and a filtering assembly. The top of the mixing box is provided with an opening, and a sealing plate is fixedly mounted on the inner wall of the opening. The defoaming device for preparing a water-based acrylic emulsion can fully fuse the emulsion during the emulsion processing process, thereby increasing the speed of emulsion production. Furthermore, by cooperating with a fixed side plate, a filter hopper, an annular limit plate, and a filter plate, the fused emulsion can be filtered before being discharged. This removes bubbles from the emulsion, preventing excessive bubbles from affecting the quality of the emulsion after processing. This arrangement also facilitates removal and cleaning of the filter plate, preventing clogging of the filter plate by solid matter in the emulsion.

[0004] Although the above-mentioned defoaming device can remove bubbles in the emulsion by filtering through the filter plate, the distance between the filter plate and the lower container is high. When the emulsion drips through the filter holes onto the emulsion in the lower container, bubbles will splash out again, affecting the quality of emulsion preparation. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a defoaming device for preparing an acrylic ester composite emulsion, which has the advantages of reducing the distance between the filter plate and the emulsion below, allowing the filter plate to move upward as the emulsion level rises, maintaining the distance between the filter plate and the emulsion below, and avoiding bubbles from splashing out again when the emulsion drips through the filter holes of the filter plate. This solves the problem that although the filter plate can remove bubbles in the emulsion by filtering, the distance between the filter plate and the container below is high, and bubbles will splash out again when the emulsion drips through the filter holes onto the emulsion in the container below, thereby affecting the quality of the emulsion preparation.

[0006] In order to achieve the above-mentioned purpose of reducing the distance between the filter plate and the emulsion below, allowing the filter plate to move upward as the emulsion level rises, maintaining the distance between the filter plate and the emulsion below, and avoiding bubbles splashing out again when the emulsion drips through the filter holes of the filter plate, the present application provides the following technical solutions: A defoaming device for preparing an acrylate composite emulsion, comprising a mixing mechanism, a collecting barrel being provided below the mixing mechanism, a filter plate being slidingly provided inside the collecting barrel, a plurality of buoyancy rings being provided at the bottom of the filter plate, a mounting seat being provided at the top of the filter plate, a pull rod being installed in the mounting seat by bolts, and a pulling frame being provided at one end of the pull rod.

[0007] Through the above solution, the buoyancy ring is set so that when the emulsion level in the collection barrel rises, the buoyancy ring can drive the filter plate to move upward, fix the height between the filter plate and the emulsion level, and achieve the effect of reducing the distance between the filter plate and the emulsion below. The filter plate can move upward with the rise of the emulsion level, maintain the distance between the filter plate and the emulsion below, and avoid the problem of bubbles splashing again when the emulsion drips through the filter holes of the filter plate.

[0008] Furthermore, there are two pull rods, one end of which is installed on both sides of the top of the filter plate through two mounting seats, the middle outer surfaces of the two pull rods are slidably arranged in the middle inner walls of the two limit plates, and one end of the two limit plates is arranged on both sides of the mixing mechanism.

[0009] Through the above solution, the two pull rods cooperate with the two limit plates to fix the angle of the filter plate during movement, thereby improving the stability of the filter plate during movement.

[0010] Furthermore, a movable base is provided at the bottom of the collection barrel.

[0011] Through the above solution, the movable base provided at the bottom of the collecting barrel can conveniently move the collecting barrel away from the bottom of the mixing mechanism, so as to facilitate the collection barrel to be moved to another position for the next step of processing the emulsion in the collecting barrel.

[0012] Furthermore, two lifting ears are provided on both sides of the collecting bucket through two supporting frames.

[0013] According to the above solution, the collecting bucket can be conveniently lifted by the two lifting ears provided on both sides of the collecting bucket.

[0014] Furthermore, a mounting plate is provided on one side of the mixing mechanism, and one side of the mounting plate is rotatably connected to one end of the threaded rod.

[0015] With the above solution, the position of the threaded rod can be fixed by setting the mounting plate, thereby improving the stability of the threaded rod during rotation.

[0016] Furthermore, the middle outer surface of the threaded rod is threadedly connected to the middle inner wall of the connecting plate, one end of the threaded rod is arranged at one end of the motor, the bottom of the motor is arranged on one side of the mixing mechanism through a fixing frame, and two pushing blocks are arranged at both ends of the connecting plate through a fixing rod.

[0017] Through the above solution, the motor can drive the threaded rod to rotate, so that the threaded rod drives the connecting plate to move, and then the connecting plate drives the pushing block to move.

[0018] Furthermore, the top of the inner wall of the pulling frame is slidably connected to the top outer surface of the pushing block, and the top outer surface of the pushing block is inclined.

[0019] Through the above scheme, the inclined setting of the top outer surface of the pushing block can make the pushing block move the pulling frame upward when moving inside the pulling frame, so that the pulling frame can drive the filter plate upward through the pull rod, and the pull rod can drive the filter plate and the buoyancy ring upward to above the collecting bucket, so that the collecting bucket can be moved away from under the mixing mechanism, avoiding the movement of the collecting bucket being restricted by the filter plate and the buoyancy ring.

[0020] Furthermore, the inner wall of one side of the middle portion of the connecting plate is slidably arranged on the outer surface of the middle portion of the limiting rod, and one end of the limiting rod is arranged on one side of the mounting plate.

[0021] Through the above scheme, the angle of the connecting plate during movement can be fixed by sliding the inner wall of one side of the middle part of the connecting plate on the outer surface of the middle part of the limiting rod, thereby improving the stability of the connecting plate during movement, so that the connecting plate can smoothly drive the pushing block to be inserted into the pulling frame.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The invention discloses a defoaming device for preparing an acrylic ester composite emulsion. The buoyancy ring is provided so that when the emulsion liquid level in a collection barrel rises, the buoyancy ring can drive a filter plate to move upward, fix the height between the filter plate and the emulsion liquid level, thereby reducing the distance between the filter plate and the emulsion below. The filter plate can move upward as the emulsion liquid level rises, maintains the distance between the filter plate and the emulsion below, and avoids the problem of bubbles splashing out again when the emulsion drips through the filter holes of the filter plate.

[0037] See also Figure 3 and Figure 4 A mounting plate 16 is provided on one side of the mixing mechanism 1, and one side of the mounting plate 16 is rotatably connected to one end of the threaded rod 12. The position of the threaded rod 12 can be fixed by setting the mounting plate 16, thereby improving the stability of the threaded rod 12 during rotation.

[0038] See also Figure 1 、 Figure 3 and Figure 4 The outer surface of the middle part of the threaded rod 12 is threadedly connected to the inner wall of the middle part of the connecting plate 13. One end of the threaded rod 12 is arranged at one end of the motor 11. The bottom of the motor 11 is arranged on one side of the mixing mechanism 1 through a fixed frame. Two pushing blocks 14 are arranged at both ends of the connecting plate 13 through a fixed rod.

The inner wall of one side in the middle of the connecting plate 13 slides on the outer surface of the middle part of the limiting rod 15 to fix the angle of the connecting plate 13 when it moves, thereby improving the stability of the connecting plate 13 when it moves, so that the connecting plate 13 can smoothly drive the pushing block 14 to be inserted into the pulling frame 8.

[0041] In this embodiment, a defoaming device for preparing an acrylic composite emulsion is provided. By setting a buoyancy ring 4, when the emulsion level in the collection barrel 2 rises, the buoyancy ring 4 can drive the filter plate 3 to move upward, fixing the height between the filter plate 3 and the emulsion level, thereby reducing the distance between the filter plate 3 and the emulsion below. The filter plate 3 can move upward as the emulsion level rises, maintaining the distance between the filter plate 3 and the emulsion below, and avoiding the problem of bubbles splashing again when the emulsion drips through the filter holes of the filter plate 3.

[0042] It should be noted that the number and specifications of the buoyancy rings 4 can be set according to the size of the filter plate 3 and the buoyancy required for the filter plate 3 to rise. The filter plate 3 is made of lightweight plastic material.

[0043] The working principle of the above embodiment is as follows: the composite emulsion raw material is put into the mixing mechanism 1 for mixing. When the emulsion is mixed, the emulsion is poured onto the filter plate 3 below through the valve at the bottom of the mixing mechanism 1. The emulsion passes through the filter holes of the filter plate 3, so that the filter plate 3 filters the bubbles in the emulsion. When the emulsion drips downward from the filter holes of the filter plate 3, it enters the collecting bucket 2. The emulsion level in the collecting bucket 2 continues to rise. The rising emulsion level will cause the buoyancy ring 4 to drive the filter plate 3 to move upward, so that the filter plate 3 moves upward with the emulsion level. When the filter plate 3 moves upward, it will drive the pull frame 8 to move upward through the pull rod 6, so that the pull frame 8 moves to the push block 14. At one end, until the collecting bucket 2 completes the collection of the emulsion, the motor 11 works to drive the connecting plate 13 to move toward the mixing mechanism 1, and the connecting plate 13 drives the pushing block 14 to be inserted into the pulling frame 8. The inclined outer surface of the top of the pushing block 14 will cause the pushing block 14 to push the pulling frame 8 upward through the top of the inner wall of the pulling frame 8, so that the pulling frame 8 drives the filter plate 3 upward through the pull rod 6, and the filter plate 3 and the buoyancy ring 4 move upward to above the collecting bucket 2, and the collecting bucket 2 is moved away from the bottom of the mixing mechanism 1 through the movable base 9 at the bottom of the collecting bucket 2. When the filter plate 3 needs to be cleaned, the filter plate 3 is separated from the pull rod 6 by removing the bolts on the mounting seat 5, and the filter plate 3 is disassembled for cleaning.
