Description

Technical Field

[0001] The utility model relates to the technical field of solid phase reaction devices, in particular to an energy-saving solid phase heating reaction device. Background Art

[0002] Solid phase heating devices transfer heat to the solid phase through different heating methods to achieve functions such as drying, purification and modification of the solid phase. Such devices have been widely used in metallurgy, chemical industry, coal, medicine and industrial production fields.

[0003] Solid phase heating devices are mainly divided into two types of structures: intermittent and continuous. In the intermittent method, the solid phase material or powder is placed in a fixed container, and the solid phase is heated to a certain temperature by external heating, and then poured and cooled. In the continuous production process, the solid phase is transferred horizontally or vertically in a fixed container, and gradually cools down in the subsequent movement after being heated in the heating area. However, both methods have disadvantages. The intermittent production efficiency is low, the temperature distribution is uneven, and the high-temperature solid phase cooling leads to a large amount of energy waste and secondary pollution. The continuous method fails to effectively improve energy utilization, and is prone to cause safety accidents such as blockage and explosion when volatile components are present.

[0004] Since the solid phase has a large specific heat capacity and a low thermal conductivity, and the stacking method has a significant effect on the heat transfer coefficient, the energy consumption of the solid phase heating device is high and the energy utilization rate is low. In addition, due to the uneven temperature distribution in the solid phase stack, it often leads to a decline in product quality and an increase in waste. Although traditional solid phase heating devices are diverse in form, they are generally limited by the characteristics of solid phase reactions and heat transfer, and have the disadvantages of low energy utilization, large heat loss, and easy environmental pollution and safety accidents.

[0007] Furthermore, the protective shell includes a first shell and a second shell; the second shell is arranged inside the first shell, and a sewage outlet is arranged on the top of the first shell, and the sewage outlet is used to discharge exhaust gas; an insulating box body is arranged outside the protective shell, and a chamber is left in the insulating box body.

[0008] Furthermore, the material discharge assembly is arranged at the bottom end of the second shell, and a valve is arranged at the bottom end of the first shell, and the valve is used to control the feeding of the material through the feed port.

[0009] Furthermore, the material discharge assembly is arranged at the bottom end of the first shell, and a valve is arranged at the bottom end of the second shell, and the valve is used to control the feeding of the material through the feed port.

[0010] Furthermore, the unloading assembly includes a discharge pipe and a rotary valve; an external cooling device is provided outside the discharge pipe, and the rotary valve is used to control the discharge of material from the discharge port.

[0012] The beneficial effects of the utility model are:

[0013] 1. After the solid raw material enters the protective shell through the push plate, it continuously exchanges heat with the high-temperature material on the other side of the first shell during its movement to the heating body area. This process allows the raw material to be effectively preheated before heating, and recycles the waste heat of the heated solid phase, thereby avoiding the problems of high energy consumption and low energy utilization in the prior art. By making full use of the low temperature effect of the solid phase feed in the shell, the temperature of the high-temperature solid phase after heating can be quickly reduced, thereby improving the continuous production efficiency of the device.

[0014] 2. The feeding component adopts the valve and push plate drive mode, which can realize the continuous feeding of loose solid phase, effectively reduce the prefabrication cost of raw materials, and is conducive to the rise and discharge of volatile components. Combined with the bottom feeding and top heating mode of this device, it can prevent the solid phase adhesion and blockage caused by the condensation of volatile components. Through the speed and distance of the push plate and the second drive mechanism to push the material, the utility model can accurately control the solid phase chemical reaction process under the stacking state, effectively solving the problem of unstable product quality in the prior art.
