The utility model relates to the technical field of geotextile production, disclose a kind of polyester staple fibre carding machine with feeding mechanism, including machine body, the inside of left side of machine body top is provided with feeding roller, the left side of machine body top is provided for the feeding mechanism of the uniform feeding of polyester staple fibre is fed in upper material.The polyester staple fibre carding machine with feeding mechanism can control servo motor to start driving screw rod rotation during use, the screw rod rotation simultaneously utilizes the threaded sleeve of thread connection to drive movable seat to move back and forth, and can drive feeding box to move back and forth on the top of feeding roller, after polyester fibre material is introduced into the inside of feeding box, it can be driven to make fibre material uniformly exported downward on the top of feeding conveyor belt by the front and back of feeding box, polyester fibre is uniformly fed in upper material, improve carding processing effect, solve the problem that polyester fibre is not conveniently fed in upper material.

The utility model provides a swing type screening device of plastic recycling, including the blanking base, the bottom rotation of blanking base is connected with the rotating base, and the rotating base bottom is equipped with the discharge gate, the eccentric position of rotating base bottom is arranged to the discharge gate, the below of blanking base is equipped with the filter screen frame, is equipped with the filter screen mesh plate on the filter screen frame, the top of filter screen frame is equipped with the material shifting guide plate. The utility model discloses through the work of control motor support, makes the output shaft on motor support so is equipped with the drive gear and the external gear that the rotating base upper end sets is engaged transmission, drives the rotating base to rotate, thereby the rotating change position of the discharge gate that rotating base bottom sets, in the process that material is along the discharge gate guide and falls, makes the falling track of material to rotate swing, thereby effectively even the material is scattered on the filter screen mesh plate top, improves the screening efficiency of filter screen mesh plate.

This application discloses an in-situ preparation method for a catalyst, comprising the following steps: gasifying a nitrogen-containing substance and / or a phosphorus-containing substance to obtain a mixed gas, passing it into a reactor containing a support, and performing heat treatment I and heat treatment II to obtain the catalyst. This method enables the uniform introduction of active components and additives, resulting in a uniform distribution of active sites in the prepared catalyst, which is beneficial for improving the catalyst's activity and selectivity. When used in the reaction of acetate and NH3, the catalyst can suppress side reactions and achieve high acetonitrile selectivity. It avoids corrosiveness to reaction equipment, provides mild reaction conditions, has high atom utilization, and is suitable for continuous, stable, and large-scale production.

The invention discloses a waste heat recovery heat exchanger and a small gas turbine. Comprises: a housing arranged in an annular shape; the multiple heat exchange pipes extend in the axis direction of the shell, and the multiple heat exchange pipes are tightly arranged in the shell; a first channel used for flowing of a low-temperature medium is formed in the heat exchange pipe, an opening of the first channel is formed in the end face of the shell, a second channel used for flowing of a high-temperature medium is formed outside the heat exchange pipe, and an opening of the second channel is formed in the side face of the shell. And the low-temperature medium and the high-temperature medium exchange heat through the pipe wall of the heat exchange pipe. The compact degree and the heat exchange efficiency of the heat exchanger can be improved, and the flow resistance can be reduced.
