The invention discloses an adjustable air inflation flotation column which comprises an adjustable air inflation component. At least three air inflation discs are used in the adjustable air inflation component, so that the adjustable air inflation component has at least three air inflation states. In different air inflation states, air supply amount is changed, the contacting area of the air inflation component and ore pulp is changed along with the air supply amount, and accordingly air inflation capacity can carry out horizontal quick response according to the components of the ore pulp. A steady flow plate is fixed on a first air inflation disc of the adjustable air inflation component through a supporting piece, the height of the steady flow plate changes along with changing of the height of the adjustable air inflation component, and ore particles and air bubbles can have enough time to be combined.

The invention discloses a vehicle tire inflating auxiliary device, and belongs to tools for mounting and dismounting air valves. The vehicle tire inflating auxiliary device comprises a sleeve a, a sleeve b, a hollow inner tube and a valve-core rotating bar. The sleeve a and the sleeve b are sleeved on the outer side of the inner tube, the valve-core rotating bar is inserted into the inner tube through the end of the inner tube. By the improved technology, the vehicle tire inflating auxiliary device has the advantages that before inflation, the valve core is mounted into the device through a valve core inlet port, and inflation and valve core mounting can be finished at one step without air leakage; the valve-core rotating bar can be used as a normal valve core key, the valve core can be mounted rapidly, and operation is facilitated; and a valve core ejector pin of the valve-core rotating bar can be used for opening an air hole of the valve core inside the device so that reinflation can be implemented without secondary operation.

The invention relates to the field of coal slurry mixing and flotation treatment, and specifically relates to swinging-stirring flotation equipment with a self-slurry-mixing function. The swinging-stirring flotation equipment disclosed by the invention at least comprises a flotation cell, wherein a micro-bubble generation bed is arranged in the flotation cell; the micro-bubble generation bed comprises micro-bubble tubes; and a connection arm is arranged at each of the two ends of each micro-bubble tube to fix the co-end part of the micro-bubble tube. The equipment further comprises a gas pipeline, wherein the gas pipeline is communicated with the tube cavity of each micro-bubble tube through a prearranged gas channel in the corresponding connection arm; and micro-bubble generation holes used for ejecting a gas are densely distributed in the tube wall of each micro-bubble tube. The equipment further comprises power arms, wherein the two power arms are provided, and symmetrically arranged at the two sides of the micro-bubble generation bed; and a stirring baffle extends from the bottommost end of each micro-bubble tube, and the surface of each stirring baffle is vertical to the swinging direction of the micro-bubble generation bed. The equipment disclosed by the invention has the advantages of being great in micro-bubble flotation effect, easier in bubble mineralization, free from flotation 'dead areas' in the flotation cell, and more stable in foam layer; and the working efficiency and the flotation effect can both be effectively ensured.

The invention discloses a large-air-volume inflator. The large-air-volume inflator comprises an outer pipe, a middle pipe and an inner pipe. The front end of the outer pipe is fixedly connected with a front cover in a sealed manner. The front end of the inner pipe is fixedly connected with the front cover in a sealed manner. An air outlet assembly is arranged on the front cover. The rear end of the middle pipe extends out of the rear end of the outer pipe and is fixedly connected with a rear cover in a sealed manner. A first one-way seal piston assembly is fixedly arranged at the front end of the middle pipe. A second one-way seal piston assembly is fixedly arranged at the lower end of the inner pipe. The large-air-volume inflator is characterized in that a first ventilation opening is formed in the side wall of the front end of the middle pipe; a second ventilation opening is formed in the side wall of the front end of the inner pipe; a first one-way air inlet valve which can only introduce air into the inner pipe is arranged in the second one-way seal piston assembly; and a second one-way air inlet valve which can only introduce air into the inner pipe or the air outlet assembly is arranged at the position of the second ventilation opening. The large-air-volume inflator has the beneficial effects that compared with a traditional single-cylinder inflator, the single-time inflation volume of the large-air-volume inflator is large, the number of tire inflation times can be halved, the tire inflation time is greatly saved, the inflation efficiency is improved, and meanwhile the effect of saving labor is achieved.

The invention relates to high-altitude rescue costume comprising a rescue costume body, wherein the rescue costume body is provided with an air loading cavity filled with gas to generate buoyancy force; two shoulders of the rescue costume body are also fixedly provided with air bags filled with gas to generate buoyancy force; and the air loading cavity on the rescue costume body and the air bags on the two shoulders of the rescue costume body are provided with air inflating joints. According to the invention, the high-altitude rescue costume has advantages of simple use method, obvious rescue effect and small size.
