A dust proof sliding mat for a shifter comprises a main sliding mat, a first auxiliary sliding mat and a second auxiliary sliding mat; a first strip-shaped hole which is in the left-right direction is formed in the main sliding mat 1; the first auxiliary sliding mat is installed under the first strip-shaped hole; a second strip-shaped hole which is in the left-right direction is formed in the auxiliary sliding mat to be corresponding to the first strip-shaped hole; the second auxiliary sliding mat is installed under the first auxiliary sliding mat; a position on the second auxiliary sliding mat, which is corresponding to the second strip-shaped hole, is provided with a rounded hole which is used for assembling a shift rod; the first auxiliary sliding mat and the second sliding mat are installed in a left-right directional sliding hole which is formed in the rear side of the main sliding mat. The dust proof sliding mat for the shifter has the advantages of being attractive in appearance, satisfying requirements for the shifter in function due to the three-layer integrated structure, having a good dust proof effect, improving the structural intensity of the main sliding mat, enabling the service life of the main sliding mat to be prolonged and reducing the fault rate and reducing maintenance costs.

The invention relates to the field of die processing, in particular to an automatic steel tube punching machine. The automatic steel tube punching machine comprises a worktable, as well as a guiding plate and a punching mechanism which are both positioned above the worktable, wherein the punching mechanism comprises an upper punch die doing reciprocating motion and a lower punch die fixed on the worktable; a lifting mechanism is further arranged below the worktable and comprises an inclined support plate, a first connecting rod, a link, a base and a second connecting rod; the support plate is positioned below the discharge opening of the lower punch die; the lower end of the support plate is connected to the upper end of the first connecting rod; the lower end of the first connecting rod is hinged to one end of the link; the other end of the link is hinged to the lower end of the second connecting rod; the middle of the link is hinged to the base; and the upper end of the second connecting rod is propped against the lower end, far away from the punching mechanism, of the guiding plate. The invention aims to provide the automatic steel tube punching machine to solve the problem that in the prior art, as a steel tube is obliquely fed into the punch dies, notches at the two ends of the punched steel tube have high probability of cracking.

The invention relates to the technical field of sewage treatment equipment, and discloses a secondary sedimentation tank suitable for glass processing wastewater treatment, including a tank body, a sludge bucket is provided at the bottom of the tank body, and one side of the sludge bucket is fixed A mud outlet pipe is installed, a central cylinder is fixedly connected to the middle of the sludge hopper, a water inlet pipe is fixedly connected to one side of the bottom of the central cylinder, and a water outlet pipe is fixedly connected to the upper end of the central cylinder. Through the setting of the mud scraping device, when the mud scraping device is installed, the mud scraper will stick to the bottom of the pool under the action of the air bag to prevent the gap between the mud scraper and the bottom of the pool, resulting in incomplete scraping and affecting the separation efficiency. When the mud scraper scrapes the sludge, the air bag has a tendency to compress downward under the static pressure of the water in the pool. When the mud scraper is worn out, the air bag will squeeze the mud scraper so that the mud scraper is always close to the pool To ensure that there will be no gap between the mud scraper and the bottom of the pool, and avoid the problems of incomplete scraping and poor mud scraping effect.

The invention discloses a light-emitting mask comprising a light-emitting component and a mask body and further comprising a framework and ear hooks installed on the framework, wherein the mask body is a light guide board fixed to the framework; the light-emitting component is installed on the framework; the light-emitting component corresponds to the light guide point on the light guide board; the framework comprises an inner frame and an outer frame which are buckled with each other; the light guide board is fixed between the inner frame and the outer frame. The light guide board can cover the whole face, only a strip-shaped framework part of the whole light guide board is shielded, the shielded part of the light guide board is the eye part of the user, and the user experience is good; the light guide board does not make direct contact with the face, frequent cleaning is not required, use is convenient and rapid, and sanitation is achieved; heat is diffused out through cooling holes and cooling fins; the whole outer frame and the light guide board can be better attached to each other through a pressing strip, the sealing performance is better, gaps are avoided, light is not leaked easily, and water or dust does not enter the light-emitting mask easily.

The invention provides a permanent magnet motor rotor capable of resisting to high temperature and a low air pressure environment. The rotor comprises a rotating shaft, a rotor support, magnetic steel, a baffle and a sheath. The rotating shaft is connected with the rotor support through multiple keys, and the baffle is fixed at two sides of the rotor support; the magnetic steel is fixed on the rotor support, and the sheath fixes the magnetic steel through interference fit; when the permanent magnet motor rotor works, when the temperature rises, no gap is arranged between the rotor support andthe rotating shaft, so that heat transfer characteristics are good, and the temperature is brought out in time. Flat keys and the rotor support are integrated into one body to present the structure ofthe inner circular teeth of the rotor support, the phenomenon of gaps due to the connection of the flat keys is avoided, and good heat conduction effect can be kept. The invention provides a structure of connection of the rotating shaft and the rotor support through multiple keys, a plurality of keyways are arranged on the rotating shaft, teeth are arranged on the rotor support so that the rotorsupport is expanded to tighten the key connection and the heat conduction performance is not decreased so as to conduct the temperature of the magnetic steel of the rotor and reduce the risk of the high-temperature demagnetization.

The invention provides a solid waste gasification power generation method, which relates to the technical field of waste power generation. The solid waste gasification power generation method is completed by a solid waste gasification power generation device, thereby realizing solid waste gasification power generation. The invention solves the problems that the existing waste gasification power generation method has poor heat recovery effect when waste is burned, and cannot recover heat in multiple layers and angles.
