This utility model provides a polyester resin filter, relating to the field of unsaturated polyester resin filtration technology. The utility model includes elongated grooves formed on the inner walls of both sides of a heating chamber. A U-shaped frame is slidably connected inside the elongated grooves. A first motor is fixedly mounted on the horizontal surface of the bottom of the U-shaped frame. A fan is fixedly mounted on the output end of the first motor via a coupling. Heaters are fixedly mounted on the inner walls of both sides of the heating chamber. This utility model uses a heating device to heat the space inside the heating chamber, while the fan blows the heat generated by the heaters onto the unsaturated polyester resin solution inside the heating chamber, heating it and increasing its fluidity. This facilitates the unsaturated polyester resin solution to pass through the filter screen more quickly, thereby improving filtration efficiency.

The application discloses a pressure swing adsorption oxygen generator and relates to the technical field of oxygen generators. The pressure swing adsorption oxygen generator comprises an oxygen generator body. An air outlet assembly is arranged on the side wall of the oxygen generator body. A second buffer assembly is arranged in the air outlet assembly. A protection assembly is arranged on the end surface of the air outlet assembly on the outer side of the second buffer assembly. A control assembly is arranged on the inner side of the second buffer assembly. A first buffer assembly is arranged on the other end of the second buffer assembly in the air outlet assembly. The first buffer assembly and the second buffer assembly are arranged to weaken the kinetic energy of the gas multiple times, so that the high-quality noise reduction of the gas is realized, and the noise during air outlet is controlled at a low decibel.

The utility model discloses a kind of quick filtering device in paper towel processing, it is related to paper towel production technical field, including collection frame, the center top of the collection frame is provided with disc type filter box, the bottom of the disc type filter box is provided with filter hole, the inside of the disc type filter box is provided with scraping strip, and the filter hole and scraping strip are used to remove mixed paper pulp internal fiber bundle, not completely decomposed lignin fragment and resin precipitate.This utility model passes through filter hole and disc type filter box, delicate paper pulp will pass through filter hole and fall to the inside of collection frame, and the lignin fragment and resin precipitate possibly remaining in paper pulp inside will be left in the top of filter hole. Thus it will reach the filtering effect to paper pulp internal lignin fragment and resin precipitate. Scattering paper pulp helps to promote the separation of small fiber and impurity, so that delicate paper pulp is more easily passed through filter hole, and larger impurity is intercepted above filter hole.

This utility model relates to a valve with a filtering function, belonging to the field of valve technology. It includes a valve body and a connecting pipe fixedly connected to one end of the valve body. A filter pipe is provided at the end of the connecting pipe away from the valve body. The filter pipe contains a detachable filter structure, which includes a filter plate slidably connected inside the filter pipe. This valve with a filtering function, by setting the filter plate and a positioning block, can position and install the filter plate inside the filter pipe. A flexible locking rod can then lock and fix the positioning block. A return spring and a movable baffle allow the flexible locking rod to elastically displace, generating pressure on the positioning block. This also facilitates the pulling of the flexible locking rod by the operator, making it easy to install and remove the filter plate, thus improving installation efficiency.

The utility model discloses a ground horizontal type dust collector which comprises a main machine shell, driving wheels are arranged on the bottom face of the main machine shell, and an installation opening is formed in the front end of the main machine shell. The dust collection bin is detachably installed at the front end of the main machine shell, an air inlet pipeline is arranged in the dust collection bin, the front end of the air inlet pipeline is connected with the installation opening, the dust collection bin is provided with a vertical pipe, a suction pipeline is arranged at the lower end of the vertical pipe, the air inlet pipeline is communicated with the vertical pipe, and a turbulent flow filter cap is installed at the top of the vertical pipe; and the dust suction pump is installed at the tail end of the main machine shell, a filter screen is installed between the dust suction pump and the dust suction bin, and the end face of the suction pipeline makes contact with the filter screen. The dust collector has the advantages that the air inlet pipeline, the vertical pipe and the suction pipeline which are arranged in the dust collection bin are communicated, the structure can prolong the retention time of dust in the dust collection bin, the separation effect of the dust collector can be improved, and the using effect of the dust collector is improved.
