Description

Technical Field

[0001] The utility model relates to the technical field of mixers with rotary stirring devices in fixed containers, and particularly relates to an aqueous paint mixer. Background Art

[0002] As is well known, during the production and manufacturing process of paints, it is necessary to stir the paints to make them more uniform. However, the paint raw materials usually contain solid components, which are generally dispersed by self-impact and crushing through stirring and finally fused together. However, there are always particles that cannot be dissolved at the end of stirring, which affects the use of the paint. In order to separate the solid components in the paint raw materials in advance, a sieve hopper is usually fixedly installed at the feed port at the bottom of the cover plate. After long-term use, the sieve hopper is prone to blockage and needs to be replaced. However, since the sieve hopper is fixedly installed on the cover plate, if it needs to be replaced, the entire cover plate needs to be replaced, thus increasing the cost of replacement and use. Therefore, it is necessary to provide an aqueous paint mixer to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the prior art that it is inconvenient to replace the sieve hopper alone, etc., and thus an aqueous paint mixer is proposed.

A plurality of crushing rods are fixedly arranged on the surface of the rotating rod, a triangular rod is vertically fixedly arranged at the bottom of the rotating rod, and the triangular rod is located inside the triangular groove.

[0006] Further, a sieve hopper is annularly arranged on the outer side of the bottom of the cover plate, a through hole is opened at the center of the bottom of the sieve hopper, the bottom of the rotating rod passes through the through hole, and a plurality of crushing rods are located inside the sieve hopper. A limiting ring is annularly fixedly arranged at the top of the sieve hopper, and an annular groove is annularly opened inside the outer side of the bottom of the cover plate, and the limiting ring is located inside the annular groove.

[0007] Further, clamping plates are vertically and fixedly arranged at both ends of the top of the limit ring, and the top ends of the clamping plates penetrate and extend outside the top of the cover plate. Card slots are formed in the top end faces of the two clamping plates, and the card slots are located on the cover plate. Buckles are fixedly arranged at both ends of the top of the cover plate. L-shaped clamping rods are slidably arranged inside the two buckles. The outer ends of the two L-shaped clamping rods are respectively clamped into the two card slots, and a spring is fixedly connected between the inner ends of the bottoms of the two L-shaped clamping rods.

[0009] The beneficial effects of the utility model are as follows: When it is necessary to replace the screening hopper alone, by pulling the two L-shaped clamping rods to move closer to each other on the cover plate to compress the spring, the two L-shaped clamping rods move closer to each other inside the two buckles and leave the two card slots, and then push the two clamping plates to move downward and leave the cover plate, so as to facilitate the removal of the screening hopper alone from the cover plate. Then, place a new screening hopper at the bottom of the cover plate, so that the limit ring is clamped into the annular groove, and then the two clamping plates move upward to the cover plate. Release the two L-shaped clamping rods, so that the outer ends of the two L-shaped clamping rods move away from each other under the action of the spring rebound force, and then the outer ends of the two L-shaped clamping rods move away from each other and are respectively clamped into the two card slots, so as to facilitate the fixing of the two clamping plates on the cover plate, and then facilitate the fixing of the screening hopper at the bottom of the cover plate, so as to facilitate the replacement of the screening hopper alone, and then there is no need to replace the cover plate as a whole, thus saving the cost of replacement and use.

Then, a new screening hopper 13 is placed at the bottom of the cover plate 4, so that the limiting ring 15 is inserted into the annular groove 16, and then the two clamping plates 17 move upward to the top of the cover plate 4. The two L-shaped clamping rods 20 are released, so that the outer ends of the two L-shaped clamping rods 20 move away from each other under the action of the rebounding force of the spring 21, and then the outer ends of the two L-shaped clamping rods 20 move away from each other on the cover plate 4 and are respectively clamped into the two clamping slots 18, so as to facilitate the fixing of the two clamping plates 17 on the cover plate 4, and further facilitate the fixed installation of the screening hopper 13 at the bottom of the cover plate 4, so as to facilitate the separate replacement of the screening hopper 13, and thus it is not necessary to replace the cover plate 4 as a whole, thereby saving the cost of replacement and use.
