The present invention belongs to the technical field of film blowing machines, and specifically is a particle filtering device for film blowing machines, comprising a film blowing machine body, wherein a feed port is provided at the top of the film blowing machine body; a screening mechanism for filtering plastic particles is arranged inside the film blowing machine body; the screening mechanism comprises two rectangular grooves and a slide groove symmetrically arranged inside the film blowing machine body, an electric push rod is fixedly installed inside the rectangular groove, and a first filter frame and a second filter frame are arranged inside the film blowing machine body; the present invention allows the electric push rod to move the first filter frame up and down, so that the first filter frame can block larger plastic particles to prevent them from continuing to fall, while plastic particles smaller than the through holes of the first filter frame can pass smoothly and continue to fall into the film blowing machine body.

This utility model discloses a coffee grinder that facilitates cleaning of the grinding chamber. It includes a grinder body with a grinding chamber installed inside. A powder outlet is located on the side wall of the grinding chamber, and a powder outlet tube is connected to the outlet. An electrostatic detector is installed on the inner wall of the grinder body, and the detector also includes an electrostatic detection plate installed on the outer wall of the grinding chamber. An ion generator is also installed on the inner wall of the grinder body, and the ion generator includes an emitting component for emitting negative ions, installed between the grinding chamber and the powder outlet tube. By installing an electrostatic detector and an ion generator inside the grinder body, this utility model can monitor the static electricity in the grinding chamber in real time and neutralize the static electricity by emitting negative ions. This effectively reduces the electrostatic adsorption of coffee powder on the inner walls of the grinding chamber and the powder outlet tube, thereby preventing clogging and residue of coffee powder, improving the cleanliness of the equipment, and facilitating the cleaning of the grinding chamber.

The invention discloses a multi-layer colorful ceramic and a preparation method thereof, and belongs to the field of building material preparation. Pyrrolidone modified lignin sulfonate and 2-(dimethylamino) ethyl methacrylate are compounded and added, so that an adhesion ligand can be provided for a ceramic pigment, the dispersion stability of the ceramic pigment is obviously improved, and antimony doped tin dioxide is combined, so that the multi-layer colorful ceramic is prepared. According to the present invention, the electrostatic adsorption can be effectively reduced, the stability of the system can be further promoted, the adhesion stability with the dry particles can be increased by adding the fatty alcohol-polyoxyethylene ether and the sodium phosphate, and the uniform adhesion of the dry particles can be further promoted under the appropriate surface tension under the action of the surfactant so as to form the uniformly dispersed dry particle layer; besides, the dry particle layer is preferably selected from transparent frit dry particles and zircon sand dry particles, so that the wear resistance of the ceramic can be improved, the ceramic appearance with a multilayer colorful effect can be formed, and the apparent quality of the ceramic is excellent.
