Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition

Abstract

The invention discloses a heat pump type reverse flow drying machine with the exhaust heat utilization and inertial dedusting functions. A draught hood of the drying machine is connected with an induced draft fan. The induced draft fan is connected with an evaporator of a heat pump system through a cyclone dedusting device and an inertial dedusting device for evacuation. The evaporator of the heat pump system is connected with a main machine through a refrigerant pipe. The main machine is connected with a condenser through the refrigerant pipe. The air outflow end of an air blower is connected with an air inflow hood through the condenser. Blades of an impeller of the induced draft fan are arranged symmetrical about the center of an impeller shaft in the radial direction in a radial manner, the dust can be cleared up in time through centrifugal force, and safety accidents are avoided. By the adoption of the heat pump type reverse flow drying machine with the exhaust heat utilization and inertial dedusting functions, drying efficiency is improved, and energy saving and emission reduction are achieved; and more importantly, the disassembly technology of the induced draft fan is improved greatly, so that pressure applied to the shaft shoulder end face of a screw by components similar to a nut component can be eliminated easily when the induced draft fan is disassembled, and the problem that the induced draft fan is locked continuously and automatically and cannot be disassembled easily under the load action due to threaded assembly is solved effectively; and the heat pump type reverse flow drying machine with the exhaust heat utilization and inertial dedusting functions is especially suitable for convenient and fast disassembly of a large-scale fan which is locked in a threaded manner, and the effect is especially remarkable.

Description

technical field [0001] The invention relates to a dryer, in particular to a heat pump type tail heat utilizing inertial dust removal countercurrent dryer which does not accumulate dust in a fan and is easy to disassemble and repair. Background technique [0002] People generally refer to drying with a drying temperature below 60 degrees Celsius as low-temperature drying. Low-temperature drying is widely used in the drying of heat-sensitive materials such as crop seeds, Chinese medicinal materials, and biological products. Due to its mature technology, strong adaptability, low operating cost and high reliability, hot air dryer is still one of the first choice equipment for low temperature drying. Low-temperature drying is less likely to utilize tail heat due to the lower temperature of exhaust gas. If the penetration and countercurrent drying of materials can be realized in the hot-air low-temperature drying process, and the tail heat can be effectively recovered, it will be...
