The invention provides a heat preservation type concrete stirring device. The heat preservation type concrete stirring device comprises a stirring cylinder, a central stirrer, a first planetary stirrer, a second planetary stirrer and a driving mechanism; the outer side wall of the stirring cylinder sinks in the radial direction of the stirring cylinder to form an annular groove, a heating coil isarranged in the annular groove, a heat conduction insulating layer is arranged between the heating coil and the groove wall of the annular groove, and the stirring cylinder is further sleeved with aninsulation heat-insulation cylinder; the central stirrer and the stirring cylinder are coaxially arranged, and the central stirrer, the first planetary stirrer and the second planetary stirrer are arranged in parallel and are all connected with the driving mechanism; and the driving mechanism drives the central stirrer to rotate around the axis of the stirring cylinder, and further drives the first planetary stirrer to revolve around the axis of the stirring cylinder and rotate around the rotating axis of the first planetary stirrer. Therefore, the uniformity of final concrete can be effectively ensured, and the temperature equilibrium of the concrete can be ensured.

The invention discloses a fuel cell power supply, comprising n parallel power supply modules, where n is a positive integer greater than 1; each power supply module is composed of an independent fuel cell module and a power battery module in parallel, with a control module and a The controllable switch; the fuel cell module contains the methanol reformer, the burner and the fuel cell stack, and the control module controls the switch for regulating the output of the power module. The present invention also provides an electric vehicle provided with a fuel cell power source. When the vehicle is running, the switch Km of any power supply module can be controlled to adapt to the target power required by the vehicle according to the power requirements of the vehicle. The switches Kf and Kb can also be adjusted according to the state of the battery SOC and the power generation state of the fuel cell module, so as to achieve the power required by the vehicle at the same time. According to the different battery temperature, the switch Kf of any power module can be controlled to heat the battery to keep the temperature of the battery balanced.

The invention relates to a vacuum sintering furnace for manufacturing vacuum glass, which comprises a vacuum set, a high temperature-resistant fan and a vacuum sintering furnace, wherein the vacuum set and the high temperature-resistant fan are arranged outside the vacuum sintering furnace, the vacuum set is communicated with the inner part of the vacuum sintering furnace by a vacuum pipeline, the high temperature-resistant fan is communicated with the inner part of the vacuum sintering furnace by a wind inlet pipe and a wind outlet pipe respectively, in the vacuum sintering furnace, wind inlet rack pipes communicated with the wind inlet pipe of the high temperature-resistant fan are evenly arranged on the inner wall of a furnace body at intervals, wind outlet rack pipes communicated with the wind outlet pipe of the high temperature-resistant fan are evenly arranged on the upper wall or / and the lower wall in the furnace body at intervals, and a furnace internal / external closed cycle is formed by the wind inlet pipe and the wind outlet pipe through the high temperature-resistant fan. The vacuum sintering furnace is low in cost price, a sealing side can be heated under normal pressure, the problem of the air leakage of the sealing side caused by a mass of air bubbles of glass powder caused by heating under a vacuum state in the furnace is solved, the quality of the vacuum glass is effectively improved, the low-pressure vacuumizing and sealing mode is particularly suitable for the manufacture of the plate vacuum glass, and the vacuum sintering furnace is small in volume and low in energy consumption.

The invention relates to the technical field of tire forming, in particular to a curing bladder mechanism and a using method thereof. The curing bladder mechanism comprises a first heating cavity which is jointly formed by a curing bladder, a first fixing plate and a second fixing plate, wherein the first fixing plate and the second fixing plate are used for fixing the curing bladder, the first heating cavity can contain a heat medium, and a temperature sensor is arranged in the first heating cavity; an operation shaft is fixedly connected to the center of the first fixing plate, a first shellis connected to the bottom of the second fixing plate, and a heating mechanism is rotationally arranged above the center of the second fixing plate and is of a closed structure; a first through holeallowing the heat medium to pass through is formed in the bottom of the heating mechanism, and a second through hole communicating with the first heating cavity is formed in the top of the heating mechanism; and a rotatable dispersing mechanism is further arranged on the periphery of the heating mechanism, and a driving mechanism for driving the heating mechanism and the dispersing mechanism to rotate is arranged in the first shell. The curing bladder mechanism is high in heating efficiency and good in temperature balancing effect, the curing quality is improved, the use amount of the heat medium is reduced, and the production cost is reduced.

The invention belongs to the technical field of battery energy and temperature control, and relates to a combined battery temperature control device. Battery heat transfer sheets are produced at front and rear sides of each single battery; heat exchange blind windows are formed at the left and right sides of each single battery; a heat exchange fluid inlet is arranged at the outer side of each heat exchange blind window; a combined battery upper cover board is formed around the outer side of the single battery; a single battery cover is formed at the top side of each single battery; a gap between each single battery cover and the combined battery upper cover board forms a fluid delivery pipe; and the heat exchange blind windows, the battery heat transfer sheets, the combined battery upper cover boards and the single battery covers are added to the single batteries to respectively form the single batteries with heat conducting sheets, and the single batteries with the heat conducting sheets are combined and assembled in series into the combined battery. The combined battery temperature control device is simple in main body structure, flexible in combination mode, safe and reliable in combination principle, and simple to use and operate, and can be used for serial and parallel combination of various rechargeable batteries.

The present invention relates to the technical field of tire building, in particular to a pressure uniformity detection device and a detection method for a reversed capsule, a pressure uniformity detection device for a reversed capsule, comprising a frame, a support cylinder, a fixed assembly for a reversed capsule, a pressure plate assembly, The pressure detection component and the control part. The pressure detection component also includes an outer large air bag and a plurality of small air bags arranged in the large air bag.
