This invention discloses a welding machine displacement device and method for welding containers. It includes two sets of spaced-apart support components, each comprising a vertically arranged support plate with a screw fixed around its circumference. An adjusting rod is threaded onto the external thread of the screw, and the other end of the adjusting rod is rotatably connected to an abutment plate via a connecting rod, for abutting against the inner wall of the container. A locking nut is provided on the screw to secure the adjusting rod. A horizontal rack is fixed between the two support plates via a connecting plate. A displacement mechanism includes a mounting base with a rotary power mechanism and a gear meshing with the rack. The mounting base has a through hole, an internal connecting rod, and a telescopic power mechanism at the top to drive a lifting rod. The bottom end of the lifting rod is fixed to a support platform for supporting the welding machine. This device can be placed inside the container and adaptively tightens the inner wall, providing a stable working platform for the welding machine.

The utility model relates to the field of exhaust cleaning, in particular to a vibration cleaning mechanism and a coal slide speed reducer deflation plug protective cover, which comprise a switching component, a first air inlet, a second air outlet and a second air outlet are arranged on the shell, a rotatable switching valve body is arranged in the cavity, and the first air outlet and the second air outlet are communicated with the switching valve body. The switching valve body can rotate under the action of airflow so that the inner channel can alternately communicate with the first air outlet and the second air outlet. And the filter screen is located at the air outlet tail ends of the first air outlet and the second air outlet and is used for generating periodic vibration under the action of alternate exhaust of the two air outlets, so that the filter screen is cleaned. A traditional deflation plug single-hole structure is prone to being blocked by pulverized coal, through the collaborative design of a vibration cleaning mechanism and a filter screen, an elastic pressing head is driven by airflow to periodically impact the filter screen, automatic cleaning is achieved, the filter screen blocking risk is remarkably reduced, and the problems of internal pressure rise, sealing damage and oil leakage caused by blocking are solved.

The invention discloses a detachable filtering system for magnetic suspension fan corridor air taking and a working method of the detachable filtering system. The filtering system comprises a box body, a drawing type filter element bracket and a filter element, the drawing type filter element bracket is arranged on the box body in a sliding manner and is provided with a pressure back-flushing self-locking mechanism; the pressure recoil self-locking mechanism comprises a first pressure guiding pipe communicated with the gallery pressure cavity and a locking component driven by air pressure in the first pressure guiding pipe. A maintenance opening is formed in the box body, and an annular air curtain generating device is arranged on the edge of the inner side of the maintenance opening; when transient positive pressure is monitored, the mechanism can instantly and automatically lock the filter element bracket in a pure mechanical mode, so that the risk that the bracket is rushed out by accidental airflow is fundamentally prevented. The safety mechanism is high in response speed, does not depend on an external power supply or complex electric control, and provides reliable physical insurance for maintenance operation.

The invention provides a photoelectric co-packaging chip preparation method for improving bottom filling creeping glue. The method comprises the following steps: step S1, providing a semiconductor substrate for reserving an optical port for mounting an optical chip; s2, manufacturing a stop block at a side position of an optical port reserved on the semiconductor substrate and used for mounting an optical chip; s3, an optical chip is attached to the semiconductor substrate according to the reserved design; and S4, carrying out glue dispensing operation on the semiconductor substrate in a manner that the bottom filling glue of the photoelectric co-packaging chip does not pollute the optical port through the blocking of the baffle block. According to the invention, the stop block is used as a physical barrier, and can effectively stop the bottom filling colloid from flowing through during the subsequent dispensing operation, so that the cleanliness of the optical port is protected, and the product yield is improved.
