The invention discloses a full-automatic device for nut blank heating. The full-automatic device comprises a vertical lifting system, a material conveying system, a material rotating heating system and a heated blank transmission separation system that are arranged sequentially; after being lifted by the vertical lifting system, blanks are sent into a bearing guide rail of the material conveying system, then are conveyed to a material receiving plate of the material rotating heating system by a feeding plate of the material conveying system; the irregular blanks return to a stock bin through a material receiving disc of the vertical lifting system, and the regular blanks are sent to a material rotating plate of the material rotating heating system, and are pushed into a heating coil to be heated uniformly; the blanks coming out after heating are subjected to temperature detection separation; and the blanks having qualified temperatures enter a forming process. Compared with the prior art, the full-automatic device has the positive effects that with the adoption of the full-automatic device, the product heating continuity is guaranteed, the product temperature stability is ensured, the product quality is improved, the labor intensity is reduced, and the working efficiency is improved to a great extent.

An air-conditioning system and its control method, the air-conditioning system includes a compressor, a four-way valve, an evaporator, a condenser, a first throttling device, the compressor passes through the four-way valve and the condenser, the first throttling device, and the evaporator The compressor forms the first circuit; the compressor forms the second circuit through the fluid control valve, the defrosting heat exchanger, the second throttling device, and the auxiliary heat exchanger; the defrosting heat exchanger can transfer its own heat through heat conduction Give the condenser to defrost the condenser. The present invention adopts a relatively independent defrosting system, which can reduce the frosting probability of the condenser only by slightly modifying the existing models, and can realize continuous heating of the indoor unit during defrosting without shutting down even if frosting occurs.

The invention provides an air conditioning system and a continuous heating control method thereof. The method comprises the steps that when it is determined that the air conditioning system enters a continuous heating mode, the initial rotating speed of an outdoor fan in the air conditioning system is recorded; the rotating speed of the outdoor fan is increased, and after the rotating speed of theoutdoor fan is increased every time, and whether the temperature of an outdoor heat exchanger of the air conditioning system reaches a first temperature threshold value is judged, wherein the first temperature threshold value is larger than or equal to zero DEG C. If the temperature of the outdoor heat exchanger reaches a first temperature threshold value, the rotating speed of the outdoor fan iskept unchanged, so that the possibility of frosting of the outdoor heat exchanger can be reduced under the condition of ensuring the heating capacity, continuous heating is achieved, the indoor environment temperature is prevented from being excessively fluctuated due to defrosting, and the heat comfort of a user is improved.

The invention provides a high-temperature continuous nitrogen heater. The high-temperature continuous nitrogen heater comprises a cylinder, a water cooling positive electrode, a water cooling negative electrode and a heating element; the heating element is mounted on the axis of the cylinder, and one end thereof is connected with the water cooling positive electrode through a slide transfer piece; the water cooling positive electrode is connected with a power supply by penetrating out of a water cooling end surface flange tightly connected to one end of the cylinder; the other end of the heating element penetrates out of a graphite baffle plate at the other end of the closed cylinder; upper and lower two water cooling negative electrodes mounted on the heating element through an electrode transfer disc are connected with the power supply after penetrating out of through holes in the wall of the cylinder; the heating element is a sandwich layer structure consisting of a graphite straight pipe on the outer layer and a graphite straight pipe with a spiral fin on the outer pipe wall on the inner layer; a spiral channel is formed between the outer-layer pipe and the inner-layer pipe through the spiral fin; and a through hole is formed in the slide transfer piece connected to one end of the heating element. The high-temperature continuous nitrogen heater solves the difficulties of thermal expansion of the heating element and high-current electric conduction, and can realize continuous heating of nitrogen currents.
