grain cooler

Abstract

The present application relates to a grain cooling machine, which includes a machine body, a condenser and a hot air blower are arranged in the body, and a spraying device, the spraying device includes a spray pipe and a regulating valve, and one end of the spray pipe is closed , the other end of the spray pipe communicates with the water source through a regulating valve, the spray pipe is provided with water spray holes at intervals, the spray pipe is located above the condenser, and the water spray holes face downward, and the control valve includes A valve and an adjustment assembly, the valve includes a valve body and a valve stem, the valve stem is rotatably connected to the valve body, and the adjustment assembly is used to control the rotation of the valve stem to control the opening of the valve. In this application, if the temperature outside the warehouse is high, open the valve, spray water to the side of the condenser, and the water evaporates to absorb heat, so as to meet the heat dissipation requirements of the condenser, without the need for high-speed rotation of the fan, thereby avoiding the use of high-speed fans, so as to achieve dusty conditions. The effect of using a cooling machine in an environment.

Description

technical field [0001] The present application relates to the field of coolers, in particular to a grain cooler. Background technique [0002] Grain coolers are mainly used in granaries, storage warehouses and other places to reduce air temperature. [0003] The grain cooler mainly includes a body and a compressor, a condenser, an expansion valve, an evaporator and a cooling fan placed in the body. [0004] Its working principle is: the medium circulates among the compressor, condenser, expansion valve and evaporator. After being compressed by the compressor, the medium is in a high temperature state, the high temperature medium enters the condenser, and exchanges heat with the air outside the warehouse at the condenser to realize the cooling of the medium; then, the cooled low temperature medium is expanded by the expansion valve. Entering the evaporator, the low-temperature medium exchanges heat with the air sucked by the cooler at the evaporator to absorb a large amount...

Problems solved by technology

[0009] In the high-speed rotating fan, in order to ensure the dynamic balance of the rotating parts such as the fan blade, the production, processing and assembly of the fan have extremely high precision. However, if there is a lot of dust in the use environment, the dust may adhere to On the fan blade, and then destroy the dynamic balance of the fan blade, the high-speed rotation of the fan blade produces eccentric force, which affects the service life of the fan, resulting in the high-speed fan being limited by its use environment, which in turn leads to the limitation of the use of the cooling machine, that is, the cooling machine Unsuitable for dusty environments
