The system for producing hydrogen and oxygen mixture gases is disclosed, which comprises an electrode unit which is formed of a plurality of negative electrodes and a plurality of positive electrodes and further includes first and second lines connected with a lower side of the electrolyte storage tank, and a third line for supplying the produced hydrogen and oxygen mixture gases to the electrolyte storage tank; a mixture gas separation filter which is installed in the interior of the electrolyte storage tank for separating the hydrogen and oxygen mixture gases from the electrolyte; a collection part which is formed in an upper side of the mixture gas separation filter for collecting the hydrogen and oxygen mixture gases which are separated by means of the mixture gas separation filter; a first filter unit which stores water for preventing the hydrogen and oxygen mixture gas, which is inputted from the collection part, reverse-flow into the collection part; and a first gas line for connecting the collection part and the first filter unit.

The invention provides a paint removing method and paint removing equipment for a surface of a metal hanging rack. Liquid-nitrogen soaking and metal particles are utilized to perform paint removal treatment on a paint resin coating on the surface of the metal hanging rack, so that the problem that paint removing effect is poor and environmental pollution is caused due to the fact that the metal hanging rack adopts an existing paint removing method is solved. The paint removing method comprises a liquid nitrogen soaking step and a multi-stage variable-frequency particle colliding step; the paint removing equipment comprises a ring-shaped rail, a self-propelling car, a liquid nitrogen slot, a metal particle impact bin and a control system; the ring-shaped rail is horizontally suspended above the liquid nitrogen slot and the metal particle impact bin; liquid nitrogen is contained in the liquid nitrogen slot; the self-propelling car is arranged on the ring-shaped rail, and can move along the ring-shaped rail; and the self-propelling car is equipped with a clamping mechanism used for clamping the metal hanging rack, a hoisting mechanism used for controlling the clamping mechanism to move up and down, and a drive mechanism used for driving the metal hanging rack to rotate along the longitudinal central shaft thereof.

The invention aims at providing an auxiliary frame mounting point structure. The auxiliary frame mounting point structure can realize drop in a collision process and reduce harm on a passenger in a passenger compartment. The auxiliary frame mounting point structure comprises an auxiliary frame provided with a mounting support and a longitudinal beam. The auxiliary frame mounting point structure is characterized inthat an internal screw thread sleeve with the bottom end open is fixed on the longitudinal beam; the mounting support is composed of a tubular support body with the two ends open and a cap body fixedly arranged at the top end of the support body, gaps corresponding in position are formed in the front end of the cap body and the front end of the upper part of the support body, a guide slot connected with the gaps is formed in the cap body, and the guide slot extends along the length direction of an automobile; and the auxiliary frame is fixedly connected with the longitudinal beam by utilizing a bolt which penetrates through the support body and the cap body and is screwed into the internal screw thread sleeve, and an anti-drop part with the diameter larger than the width of the guide slot is arranged at the bottom end of the bolt. The auxiliary frame mounting point structure has the advantages that the auxiliary frame can drop in the collision process and harm done to a passenger can be reduced.

The invention discloses a boiler flue gas waste heat recovery device and a recovery method, which belong to the technical field of flue gas waste heat recovery. A boiler flue gas waste heat recovery device includes a device shell, and a heat exchange tube is arranged inside the device shell. The upper end of the air inlet pipe is fixedly connected with the air intake pipe. In the process of waste heat recovery of the flue gas, the present invention pushes the main cleaning ball and the auxiliary cleaning ball through the flue gas flow, so that the main cleaning ball and the auxiliary cleaning ball circulate continuously in the heat exchange tube. Rolling, in the process of waste heat recovery, the inner wall of the heat exchange tube is continuously and continuously cleaned, and the flue gas particles attached to the inner wall of the heat exchange tube are cleaned, and when the main cleaning ball and the auxiliary cleaning ball complete a cleaning of the heat exchange tube, In the process of returning to the inlet end of the heat exchange tube, the processes of self-cleaning, dehydration and drying are also realized in sequence, and then enter the heat exchange tube again to clean the heat exchange tube, thereby further ensuring the cleaning effect of the heat exchange tube .

The invention relates to the technical field of building bricklaying production, in particular to an energy-saving and environment-friendly building bricklaying production device, comprising a fixed frame; There is a pushing mechanism, the middle part of the front end of the fixed frame is fixedly connected with the forming plate and the holding plate, the forming plate is located at the back side of the holding plate, the four corners of the forming plate are fixedly connected with guide columns, and the upper end of the guide column is slidingly provided with an upper pressing block mechanism, The lower end is slidingly provided with a lower pressing plate mechanism; an upper forming plate and a lower forming plate are provided to facilitate the pressing of multi-style bricklaying, which effectively increases the applicability of the same equipment and reduces the production cost of the manufacturer; the conveying box can communicate with the forming plate on the forming plate. The matching of the holes can effectively improve the utilization rate of raw materials, reduce the waste of raw materials, effectively prevent the raw materials from being scattered on the upper side of the forming plate, and affect the effect of bricklaying and pressing; control the movement of the upper pressing block mechanism and the lower pressing plate mechanism, and effectively make the bricklaying from forming Falling off in the through hole ensures the forming degree of bricklaying.
