Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a heat recovery ventilator. Background Art

[0002] A ventilator is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Modern ventilators are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling, and in boilers and industrial furnaces for ventilation and draft.

[0003] Existing fans will generate a certain amount of heat when running, especially when ventilated continuously for a long time, but when the heat is generated, natural ventilation and other means are mostly used to directly cool down, which will cause heat waste when cooling down. In addition, after a long time, dust and debris will be attached to the internal blades of the fan, which requires manual cleaning by personnel, causing inconvenience, so it still needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a heat recovery ventilator to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a heat recovery ventilator, comprising a bearing base, an air storage box, a ventilator body and a liquid storage box,

[0006] The top surface of the bearing base is respectively equipped with an air storage box, a ventilator body and a liquid storage box;

[0007] A booster pump is installed on the side end surface of the air storage box;

[0008] A fixed pipe is installed on the top surface of the inner wall of the ventilator body, and a nozzle is arranged in the fixed pipe;

[0009] The rear end surface of the ventilator body is provided with a driving mechanism, and a coil is installed on the driving mechanism;

[0010] A water pump is installed in the liquid storage tank, and the water pump is in liquid communication with the coil through a liquid inlet pipe;

[0011] The coil is in fluid communication with the liquid storage tank via a return pipe.

[0012] Preferably, the booster pump is provided with an air extraction pipe, one end of the air extraction pipe facing away from the booster pump is embedded and fixed in the air storage box, and the air storage box is in gas communication with the booster pump through the air extraction pipe. By providing the air extraction pipe on the booster pump, when the booster pump is turned on, external air can be extracted and discharged into the air storage box through the air extraction pipe.

[0013] Preferably, support blocks are welded to the bottom end face of the bearing base. There are four support blocks in total, and the four support blocks are distributed in a rectangular array relative to the bearing base. The bearing base can be installed and supported by the support blocks.

[0014] Preferably, an air inlet pipe is provided at one end of the ventilator body, and an air outlet pipe is provided at the end of the air inlet pipe away from the ventilator body. When the ventilator body is turned on, the ventilator body intakes air through the air inlet pipe and discharges air through the air outlet pipe.

[0015] Preferably, an exhaust pipe is embedded and fixed on the top end face of the fixed pipe, and the end of the exhaust pipe away from the fixed pipe is embedded and fixed in the gas storage tank. The gas storage tank is in gas communication with the fixed pipe through the exhaust pipe. By embedding and fixing the exhaust pipe on the top end face of the fixed pipe, the gas in the gas storage tank can be injected into the fixed pipe through the exhaust pipe.

[0016] Preferably, a filling pipe is embedded and fixed on the top end face of the liquid storage tank, and the filling pipe is in liquid communication with the liquid storage tank. The water body that can be cooled and recover heat can be injected into the liquid storage tank through the filling pipe for storage.

[0017] Preferably, a drain pipe is embedded and fixed on the rear end face of the liquid storage tank. A valve is installed on the drain pipe through a flange, and the drain pipe is in liquid communication with the liquid storage tank. By opening the valve on the drain pipe, the heat-exchanged water body in the liquid storage tank can be discharged.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. By setting the ventilator body in the present utility model, when a person uses the ventilator body, the person starts the driving mechanism, which can drive the blades inside the ventilator body to start rotating. In this way, the ventilator body can intake air through the air inlet pipe and discharge air through the air outlet pipe. After the processes of discharging and intaking air are completed, in order to prevent dust and debris from adhering to the blades in the ventilator body, the person is equipped with an air extraction pipe on the booster pump. In this way, when the booster pump is turned on, external gas can be extracted and discharged into the gas storage tank through the air extraction pipe. After the injection is completed, since the exhaust pipe is embedded and fixed on the top end face of the fixed pipe, the gas in the gas storage tank can be injected into the fixed pipe through the exhaust pipe. In this way, when the booster pump pressurizes, the discharged gas will be injected into the fixed pipe. Moreover, during the continuous rotation of the blades, the pressurized gas can treat the adhering dust and debris, thus avoiding the problem of inconvenient cleaning of the blades inside the ventilator body after long-term gas extraction, and further achieving the purpose of cleaning and maintenance.

[0020] 2. By setting a driving mechanism in the present utility model, when a person is using the ventilation machine body, if the driving mechanism runs for a long time and generates heat, the person can turn on the water pump in the liquid storage tank. At this time, the water pump will extract the water body for cooling and heat recovery in the liquid storage tank and transport it to the coil through the liquid inlet pipe. As the water body in the coil continuously circulates, it can exchange heat with the driving mechanism to cool down. When cooling, the water body can flow back to the liquid storage tank through the return pipe, forming a reciprocating flow. In this way, after the water body in the liquid storage tank is heated, it can be discharged through the drain pipe. Thus, the heat heats the water body, realizing the recovery and utilization of heat. After the heat of the water body is discharged and recovered, the person can inject the water body for cooling and heat recovery into the liquid storage tank again for cyclic use, thereby meeting the use requirements of heat recovery.

[0034] A water pump 15 is installed in the liquid storage tank 12, and the water pump 15 is in liquid communication with the coil 11 through a liquid inlet pipe 13;

[0035] The coil 11 is in fluid communication with a liquid storage tank 12 via a return pipe 14 .
