This utility model relates to the field of waste plastic recycling equipment, and particularly to a PET bottle flake hot washing pot. It includes a box with an internal cavity, a drive motor mounted on the box, a feed inlet located on the upper part of the box and connected to the cavity, and a discharge auger located at one end on the bottom of the box and connected to the cavity. The cavity has a regular polygonal structure, and a feeding structure is provided on the outer side of the box. The feeding structure includes a feeding channel fixed to the upper part of the box and connected to the cavity, a rotating shaft rotatably connected to the feeding channel, and a rotating paddle fixed to the rotating shaft and matched to the feeding channel. This utility model features minimal structural modifications, effectively preventing alkaline water splashing, reducing potential operational accidents, and improving the cleaning efficiency of PET bottle flakes.

The invention provides a rotary disc aerator with spiral plug flow, which overcomes the tedious structure of an oxidation ditch rotary disc aerator, is reasonable in design and good in aeration effect, and comprises a driving motor, a speed reducer, a mounting frame, a rotating shaft, a main shaft and a rotary disc which are connected in sequence, the main shaft is longitudinally distributed and is driven by a motor, and the core is that the rotating disc aerator and the water impeller are combined into a whole, so that the unification of surface flow pushing and mechanical aeration is realized.

This utility model discloses a purification device for a smokeless hot pot table, including a tabletop, a housing, an oil fume separation device, a negative pressure generating device, a catalytic purification device, a heat dissipation device, and an intelligent control device. The tabletop is located on top of the housing, while the oil fume separation device, negative pressure generating device, and catalytic purification device are all located inside the housing. The heat dissipation device is located on the side wall of the housing. The oil fume separation device, negative pressure generating device, catalytic purification device, and heat dissipation device are all electrically connected to the intelligent control device. This device has a compact overall structure, is integrated into the cooking table, saves space, and has advantages such as high-efficiency purification, energy saving and noise reduction, and convenient maintenance. It can effectively solve the problems of traditional external oil fume treatment equipment, such as large space occupation, incomplete purification, and high energy consumption, and meet the environmental protection and comfort requirements of modern catering.

This utility model relates to the technical field of railway maintenance equipment, and in particular to a common sleeper spiral spike anchoring frame, comprising a positioning sleeve arranged vertically, wherein the positioning sleeve is provided with a magnet for attracting the spike, one side of the positioning sleeve is provided with an opening for easy insertion or removal of the spike from the side, the other side of the positioning sleeve is fixedly connected with a positioning plate for fitting against the side of the sleeper's rail groove, a support rod is provided below the positioning sleeve for abutting against the bottom surface of the sleeper's rail groove, and a positioning rod is provided above the positioning sleeve for positioning the spike height. This utility model has a scientific structure and ingenious design, which can not only control the axis of the spike to be in the vertical direction, thus coaxial with the reserved hole, but also control the height of the spike, providing accurate positioning, simple operation, and convenient use, thereby improving work efficiency.

The invention relates to a pressing mechanism and a sole pressing machine for shoemaking, the pressing mechanism is provided with a supporting seat, a telescopic cavity is arranged on the supporting seat, and a following material is arranged in the telescopic cavity; when the telescopic cavity is contracted, the following material outputs power to drive a profiling block, the profiling block extends to the pressed object and presses the pressed object; the profiling block is arranged on the corresponding side of the telescopic cavity and can extend according to the curvature of the pressed object, so that the front end of the profiling block can be arranged according to the curvature of the pressed object and give appropriate pressing force to the curvature of each region. The profiling block is synchronously stressed, and the pressure is balanced, so that the pressing effect is improved, the pressing is compact, flat and smooth, and the manufacturing and use performance of the sole pressing machine is optimized. The steel ball is pushed by the machine, the profiling block is pushed by the steel ball, the profiling block forms the curvature that matches the shoe when the profiling block meets the concave-convex part of the shoe, the shoe edge can be closely and flatly attached to the shoe edge according to the curvature, seamless pressing is realized, and the manufacturing efficiency and quality are improved.
